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: Methods, systems, and devices for wireless communications are described. The described techniques provide for selecting a PRACH occasion (RO) based on downlink quality, access congestion, latency (e.g., time to next available RO), beam correspondence, random access in previous transmissions, or combinations of these factors. The user equipment (UE) may detect access congestion of synchronization signal blocks (SSBs) and select the less congested SSB in the RO selection. The UE may detect the access congestion by receiving a back-off indicator from the base station, detecting a contention resolution failure, or the number or media access control (MAC) subheaders in a random access response. In some cases, the ROs associated with different SSBs have different latencies and the UE may select the earliest available RO.

Abstract: A configurable new radio (NR) RACH procedure that may be executed by a UE and a base station is disclosed. A configuration to determine, by a user equipment, a random access procedure timeline, from multiple random access procedure timelines that each define a different duration between one or more messages that are communicated in a random access procedure can be determined or transmitted. A random access preamble can be received from the UE based on the random access procedure timeline, and a response to the random access preamble can be determined or transmitted based on the random access procedure timeline.

Abstract: Certain aspects of the present disclosure provide techniques for time division duplex configuration override. A method that may be performed by a user equipment (UE) includes detecting a period during which a configuration of a first radio access technology (RAT) conflicts with a configuration of a second RAT for a frequency band; and overriding the configuration of the second RAT with the configuration of the first RAT for the period.

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: 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a collision is to occur between a physical uplink control channel (PUCCH) transmission that includes a scheduling request (SR), and multiple physical uplink shared channel (PUSCH) transmissions in a slot. The UE may transmit, to a base station (BS), the PUCCH transmission or the multiple PUSCH transmissions based at least in part on determining whether the collision is to occur in the slot. Numerous other aspects are provided.

Abstract: Systems and methods for modularized design for inter-physical layer priority uplink control information (UCI) multiplexing are disclosed herein. A user equipment (UE) may determine a first code rate for a first portion of UCI and a second code rate for a second portion of UCI. Different code rates may be used to encode different portions of UCI (e.g., hybrid automatic repeat request acknowledgement (HARQ-ACK) bits, channel state information (CSI) reporting bits, scheduling request (SR) bits, cyclic redundancy check (CRC) bits, etc.). Further, a UE may select a group of bets offset sets based on a physical layer priority type and a UCI multiplexing type.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first serving cell for a set of transmission time intervals (TTIs) including a first TTI and receive a second slot format configuration for the first serving cell for the first TTI which is different from the first slot format configuration.

The UE may identify, for a second serving cell for the first TTI, a second communication direction indicated by one or more slot format configurations for the second serving cell. The UE may determine whether to communicate on the second serving cell for the first TTI according to the one or more slot format configurations for the second serving cell.

Abstract: Certain aspects of the present disclosure provide techniques for avoiding out of order uplink data reception upon data radio bearer (DRB) release or quality of service (QoS) flow addition. An exemplary method that may be performed by a user equipment (UE), includes receiving an indication from a base station (B S) that multiplexing of hybrid automatic retransmission request (HARQ) information and channel state information (CSI) is enabled in all physical uplink control channel (PUCCH) resources, generating a first CSI report regarding a first downlink (DL) channel from the BS, multiplexing a HARQ response to a transmission from the BS and the first CSI report in a PUCCH, and transmitting the PUCCH to the BS via one of the PUCCH resources.

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.
