Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an uplink payload in a wireless communications system. The UE may identify a set of sequences configured for conveying a payload including a set of bits, where each sequence of the set of sequences is orthogonal to each other sequence of the set of sequences. The UE may select a first sequence from the set of sequences based on a mapping between the set of sequences and payload values corresponding to the set of bits. The UE may transmit the payload including the set of bits using the first sequence.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a group-common physical downlink shared channel (PDSCH), where the group-common PDSCH is repeated for a number of repetitions. Accordingly, the UE may determine this number of repetitions and then monitor for the group-common PDSCH based on the number of repetitions. In some implementations, the group-common PDSCH may include a semi-static repetition scheme, where the number of repetitions is indicated via a group aggregation factor. Additionally or alternatively, the group-common PDSCH may include a dynamic repetition scheme, where the number of repetitions is indicated via a group repetition number. Additionally, the techniques described herein may enable the configuration for the repeated group-common PDSCH to include gaps between each repetition of the group-common PDSCH and for the UE to transmit acknowledgment feedback for the repetitions of the group-common PDSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select an uplink transmission power sharing configuration to use for transmission of one or more uplink messages. The uplink transmission power sharing configuration may be based on a first uplink transmission power capability of a first radio frequency (RF) chain of the UE and on a second uplink transmission power capability of a second RF chain of the UE. The UE may transmit the one or more uplink messages to a network entity in accordance with the uplink transmission power sharing configuration. Specifically, the UE may transmit the one or more uplink messages via the first RF chain using a first transmission power, and may transmit the one or more uplink messages via the second RF chain using a second transmission power that is different from the first transmission power.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device (such as a user equipment (UE)) may receive from a transmitting device (such as a base station), a configuration of full duplex communication resources for a set of slots. The receiving device may receive a pre-emption indication identifying that at least a portion of the full duplex communication resources in one or more slots of the set of slots is unavailable for communication, and may determine a remaining portion of the full duplex communication resources in the one or more slots based on the received pre-emption indication. The receiving device may then communicate with the transmitting device using the remaining portion of the full duplex communication resources.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmitting a channel state information (CSI) report from a user equipment (UE). The CSI report may be a UE initiated CSI report or may be based on a downlink grant. The UE may determine to transmit the CSI report based on measurement using a physical downlink control channel (PDSCH) and/or a demodulation reference signal (DMRS). The UE may determine a reference resource for CSI feedback. The UE may calculate a channel quality indicator (CQI) based on the reference resource. The UE may transmit the CQI in the CSI report on an uplink resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive a communication from a second UE. The UE may transmit, to the second UE, sidelink hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a sidelink component carrier based at least in part on the communication received from the second UE, wherein the sidelink component carrier is associated with conveying the sidelink HARQ-ACK feedback when sidelink carrier aggregation is configured for a group of UEs that includes the first UE and the second UE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may determine that a power threshold for the first device is satisfied. The first device may transition from a first type of channel state feedback processing to a second type of channel state feedback processing based at least in part on determining that the power threshold for the first device is satisfied.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify multiple regions within a subframe, such as one or more uplink regions, one or more downlink regions, and a guard region. The wireless device may identify and communicate during each region based on a timing relationship between the downlink region and the uplink region. For example, the device may expect hybrid automated repeat request (HARQ) feedback for one downlink region in the same subframe based on the proximity to the next uplink region. Another downlink region may not have HARQ feedback in the same subframe. Similarly, uplink regions may or may not be scheduled within the same subframe.

Abstract: Quasi-colocation (QCL) indication is discussed after downlink transmission. In the management of multiple transmission-reception point (TRP) downlink transmissions, a second indication of a QCL assumption for a particular downlink transmission may be transmitted to receiving user equipment (UEs) after transmission of the downlink transmission. Once a TRP passes a listen before talk (LBT) procedure in a first time interval, it may send a first downlink control information (DCI) with indication of a first QCL assumption for the transmission in the first time interval. The TRP then transmits the downlink transmission intended for part of the multi-TRP downlink transmission. Upon receiving an indication that another of the TRPs was unsuccessful in its part of the multi-TRP transmission, the TRP may transmit a second DCI in a subsequent time interval with adjustments to the QCL assumption for the UEs to use in processing the downlink transmission from the first time interval.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may be configured to transmit two or more consecutive transmissions that may be used for demodulation reference signal (DMRS) bundling. If criteria for DMRS bundling are not satisfied, the UE may generate dummy data to transmit during the skipped configured grant occasion, and may maintain phase continuity across the skipped configured grant occasion and any other PUSCHs in a set of uplink transmissions. In some examples, the UE may deprioritize DMRS bundling for sets of PUSCHs during which a PUSCH is to be skipped. If criteria for DMRS bundling are not satisfied, the UE may not maintain phase continuity across the set of PUSCHs, and may refrain from transmitting any data during the CG-PUSCH occasion.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via a first cell, downlink control information for physical downlink control channel ordered contention-free random access, wherein the downlink control information indicates a timing advance group of a second cell and one or more parameters associated with a random access message to be transmitted by the UE via the second cell, wherein the first cell and the second cell belong to different timing advance groups. The UE may transmit the random access message via the second cell according to the one or more parameters and a timing advance value determined based at least in part on the timing advance group of the second cell. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine separate uplink (UL) power limitations for multiple transmission time interval (TTI) durations based on distinct power control parameters. In some cases, an adjustment factor or a power backoff may be applied to communications using one TTI duration to ensure that total transmit power does not exceed a threshold. The UE and the serving base station may also identify one or more demodulation reference signal (DMRS) windows. UL data transmissions may be demodulated based on a DMRS sent during the same window. Transmit power control (TPC) commands may be applied at the beginning of each window. However, if an UL transmission is scheduled at the beginning of the window, the UE may wait until a DMRS transmission or until no more transmissions are scheduled for the window before applying the TPC adjustment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, in a first paging occasion, paging information that identifies a data transmission in a second paging occasion subsequent to the first paging occasion; and receive the data transmission during the second paging occasion. Numerous other aspects are provided.

Abstract: Bits for acknowledgement (ACK) and/or negative acknowledgement (NAK) may be allocated based on whether a special subframe configuration in a TDD configuration permits downlink transmission. For carrier aggregation, ACK/NAK bits may be allocated only to special subframes in component carriers (CCs) which permit downlink transmission. Also, for example, ACK/NAK bits may be allocated to all CC special subframes if a single CC is configured to allow downlink transmission on one of its special subframes. ACK/NAK bits may also be allocated to all special subframes.

Abstract: Wireless communications systems and methods related to hybrid automatic repeat request (HARQ) history feedbacks are provided. A user equipment (UE) receives one or more data blocks of a plurality of data blocks, each of the one or more data blocks received in one of a plurality of transmission occasions. The UE transmits an individual feedback for each of the one or more data blocks indicating whether the data block is received successfully. The UE transmits a feedback history report for one or more transmission occasions of the plurality of transmission occasions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate using demodulation reference signal enhancements for control channel repetitions. The UE and the base station may identify a configuration to use to receive or transmit a set of repetitions of control information on a downlink control channel, each repetition of the set of repetitions including one or more symbol periods for an instance of the repeated control information. The base station may transmit, and the UE may receive, a first set of demodulation reference signals in accordance with a first set of parameter values, a second set of demodulation reference signals in accordance with a second set of parameter values, and instances of the control information during the set of repetitions. The UE may decode the control information based on the received signals and configuration.

Abstract: A victim user equipment (UE) may experience cross-link interference (CLI) from a physical uplink shared channel (PUSCH) transmission from an aggressor UE or self-interference (SI) from a PUSCH transmission from a transmitter of the victim UE. The present disclosure provides for configuration of measurement resources and a CLI report for mitigation of CLI. A base station may transmit a configuration of the measurement resources including channel state information interference measurement (CSI-IM) resources and a configuration of a CLI report. The CSI-IM resources match PUSCH symbols or demodulation reference signal (DMRS) symbols of an aggressor UE. The victim UE measures a CLI or a SI on the CSI-IM resources. The victim UE reports the CLI or the SI to the base station according to the configuration of the CLI report. The base station may schedule transmissions to mitigate the CLI or the SI.
