Abstract: Performing UCI multiplexing includes generating PUCCH resources Z at an L1 HP procedure and an L1 LP procedure. The L1 HP procedure and the L1 LP procedure results in a plurality of HP PUCCHs and LP PUCCHs, respectively. A modified procedure for Set Q to resources Z is performed with the plurality of HP PUCCHs and LP PUCCHs as inputs. The plurality of HP PUCCHs according to starting symbols is scanned to identify an earliest starting HP PUCCH. A PUCCH from the plurality of LP PUCCHs or HP PUCCHS that overlaps with the earliest starting HP PUCCH is collected. Inter-L1 priority multiplexing is performed on the earliest starting HP PUCCH and the collected PUCCH, which may result in a new HP PUCCH. The new HP PUCCH is inserted into the Set Q. The modified procedure is repeated until there is no overlap among the HP PUCCHs and the LP PUCCHs.

Abstract: Certain aspects of the present disclosure provide techniques for uplink preemption indication. A method for wireless communication by a user equipment (UE) includes receiving at least one ULPI from a base station (BS) indicating, for each of a plurality of sets of uplink resources, a power level the UE can use for one or more uplink transmissions. The UE can determine one or more power levels indicated by the ULPI for resources allocated for the UE for uplink transmission. The allocated resources may include multiple of the sets of uplink resources. The UE can select the power level to use for uplink transmission using the allocated resources based, at least in part, on the determination. The UE sends or drops the one or more uplink transmissions according to the ULPI. A time duration of the plurality of sets of uplink resources can be longer than a configured ULPI monitoring periodicity.

Abstract: Provided is a method for a user equipment (UE), comprising: obtaining one or more indications associated with uplink transmission scheduled by one or more uplink (UL) grants, the one or more UL grants including a UL grant for a physical uplink share channel (PUSCH) with uplink control information (UCI), selecting a UL grant for transmission from the one or more UL grants based at least in part upon the one or more indications, such that the UL grant for the PUSCH with UCI is prioritized for selection, and causing a PUSCH corresponding to the selected UL grant to be transmitted.

Abstract: Certain aspects of the present disclosure relate to uplink preemption in certain systems, such as new radio (NR) systems, supporting carrier aggregation (CA) and/or multi-connectivity modes. A method for wireless communication, that can be performed by a user equipment (UE), generally includes receiving a resource assignment scheduling the UE for uplink transmission. The UE receives an indication to preempt uplink transmission on a portion of the assigned resources and determines whether to transmit on the remaining assigned resources. A method that can be performed by a base station (BS) generally includes receiving an indication from one or more UEs indicating, for each of a plurality of band combinations, a capability of the UE to transmit on a band when transmission on another band in the band combination is preempted and scheduling the one or more UEs for uplink transmission based on the indication.

Abstract: The present disclosure relates to transmitting and receiving a beam report at a UE and a base station. The base station can configure a cDRX cycle with the UE. Also, the UE can wake up during an off period of the cDRX cycle. The UE can also compare a first metric of at least one of a plurality of candidate beams and a second metric of a current beam for communication with the base station. Additionally, the UE can transmit a beam report to the base station, during the off period, based on the comparison of the first metric of the at least one of the plurality of candidate beams and the second metric of the current beam. The UE can also select, during the off period of the cDRX cycle, the at least one of the plurality of candidate beams for communication with the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a first set of grants for performing uplink transmissions between the UE and a first group of cells associated with a first radio access technology (RAT) and a second set of grants for performing uplink communication between the UE and a second group of cells associated with a second RAT. The UE may determine that a combined transmit power exceeds a total power limit or that there may be a potential of the combined power exceeding the total power limit. The UE may further perform the uplink communication with the first group of cells using the first RAT and the second group of cells using the second RAT.

Abstract: This disclosure relates to random access channel (RACH) enhancements for new radio unlicensed (NR-U) communications. Specifically, the present aspects include determining whether a gap length between a two-step random access channel (RACH) preamble transmission and a physical uplink shared channel (PUSCH) transmission satisfies a gap condition. The present aspects further include selecting a transmission procedure associated with the determined gap length for the PUSCH transmission. The present aspects further include performing the PUSCH transmission in accordance with the selected transmission procedure.

Abstract: Methods, systems, and devices are described for handling transmissions or channels in wireless communications that collide with one another. The described techniques relate to handling the collision between multiple overlapping channels (e.g., two or more channels of the same priority). For example, a collision resolution configuration may include resolving the collisions among the channels of the same priority first (e.g., feedback information transmissions first, and then control information), among the channels of the same service type first (e.g., normal channels first, and then low latency channel(s)), or across all of the channels of all priorities at once.

Abstract: Methods, systems, and devices for wireless communications are described for handling uplink grants that have associated uplink transmission that may exceed exposure limits. Exposure limits may be based on maximum permissible exposure (MPE) limits of millimeter wave transmissions and may be determined at a user equipment (UE) and provided to a base station. If the UE receives an uplink grant for a transmission in which an associated uplink transmission would exceed the exposure limits, the UE may drop the uplink transmission prior to forming a transport block, transmit control signaling to the base station to indicate the exposure limits at the UE, or combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may interrupt a user equipment (UE) during transport block (TB) encoding. The UE may cancel transmission (e.g., suppress processing) of a TB based on the interruption, such that a first subset of code blocks is encoded and a second subset is unencoded. In some cases, the UE may receive a re-transmission request for a code block including cyclic redundancy check (CRC) bits for the TB, where the CRC bits are not prepared. In one example, the UE may modify the CRC bits (e.g., set them to a common value, drop them, etc.) to reduce processing time. In another example, the base station may request re-transmission of all preempted code blocks, supporting TB CRC calculation. In another example, the base station or UE may extend a processing timeline for the re-transmission to support TB CRC calculation.

Abstract: This disclosure relates to techniques for performing wireless communications including exchanging information related to capability of processing reference signals. A user equipment device may provide capability information to a network. The capability information may indicate a number of reference signal resources that the user equipment device can process in a slot or other defined period of time. The user equipment device and the network may share a common set of definitions, counting rules, and approaches for interpreting the capability information. The network may configure reference signals for the user equipment device.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Techniques are described herein for performing out-of-order processing. The UE may receive a first downlink channel at a first time and a second downlink channel at a second time. The UE may determine that a priority of the second downlink channel is different (e.g., higher) than a priority of the first downlink channel. The UE may determine that a first uplink transmission associated with the first downlink channel is to be transmitted after a second uplink transmission associated with the second channel based on the different priorities. The UE may set one or more operations based on these determinations. In some cases, the UE may suspend processing the of the first downlink channel to process the second downlink channel.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may wake up from a sleep mode of a discontinuous reception (DRX) cycle based on receipt of uplink data. The UE may determine if an elapsed time between a prior receipt of one or more reference signals and an uplink transmission to the base station after waking up from the sleep mode is less than a threshold time value. If the elapsed time is less than the threshold time value, the UE may transmit an uplink transmission associated with the received uplink data prior to receiving one or more reference signals that may be used to update transmission parameters for uplink transmissions. If the elapsed time is at or above the threshold value, the UE may wait to receive the one or more reference signals and update the transmission parameters prior to the uplink transmission.

Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides techniques for determining timing conditions for uplink control information (UCI) processing by a user equipment (UE).

Abstract: Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may refrain from transmitting channel state information (CSI) if the CSI is configured to be transmitted during an inactive discontinuous reception (DRX) duration. The UE may determine that the CSI is configured to be transmitted during the inactive DRX duration based on determining that some or all of the configured time slot for transmitting the CSI occurs while the UE is operating in the inactive DRX duration. The UE may transmit feedback information, such as an acknowledgement (ACK), whether or not the UE drops the CSI.

Abstract: A user equipment (UE) may be configured to receive configuration information from a base station, and the configuration information may indicate at least two different random access channel (RACH) request configuration parameters that each is associated with a respective radio resource control (RRC) state. The UE may be further configured to generate a first message associated with a two-step RACH procedure including a preamble and a payload, the payload including data on an uplink data channel and at least one reference signal. The UE may be further configured to transmit the first message to the base station using at least one of the at least two different RACH request configuration parameters that corresponds to an RRC state of the UE. The preamble may be transmitted on a first set of resources associated with a RACH occasion, and the payload may be transmitted on a second set of resources.

Abstract: A user equipment (UE) may report physical uplink control channel (PUCCH) group capabilities to a network. The UE receives a request from a network for radio access capability information and reports whether a single PUCCH group having a plurality of component carriers (CC) using more than two numerologies across the CCs is supported. The UE may also receive a request from a network for radio access capability information and report whether a PUCCH group having a plurality of CC across multiple frequency bands is supported, wherein the report is configured per band combination (BC). The UE may also receive a request from a network for radio access capability information and report support for a PUCCH location configuration for a PUCCH group having a plurality of CC across multiple frequency bands, the PUCCH location configuration indicating which bands in a band combination (BC) may be used for the PUCCH.

Abstract: Systems and methods are provided for controlling behavior for overriding grants for channel state information (CSI) feedback. A user equipment (UE) may control override of a first grant of a first radio resource by a second grant of a second radio resource. The UE determines that the second radio resource at least partially overlaps with the first radio resource. The UE also determines a physical layer priority of the first grant of the first radio resource and the second grant of the second radio resource. The physical layer priority is based on at least one of the first grant of the first radio resource and the second grant of the second radio resource being configured for transmitting CSI feedback over a physical uplink shared channel (PUSCH) to a base station. The UE then generates a transmission according to the physical layer priority.

Abstract: Certain aspects of the present disclosure provide techniques for sending uplink control information. A method that may be performed by a user equipment (UE) includes receiving an uplink grant for transmission on a plurality of physical uplink shared channels (PUSCHs), the plurality of PUSCHs being located on different component carriers (CCs); identifying one or more PUSCHs of the plurality of PUSCHs on which uplink control information (UCI) can be transmitted in a slot; assigning PUSCH data to the one or more identified PUSCHs on which the UCI can be transmitted before assigning PUSCH data to remaining PUSCHs of the plurality of PUSCHs; and transmitting the UCI and the PUSCH data in the slot on the assigned PUSCHs.
