Abstract: Aspects for enhanced logical channel prioritization mapping procedures and restrictions are disclosed. In one aspect, a method of wireless communication includes receiving, by a user equipment (UE), a logical channel prioritization (LCP) restriction configuration for a logical channel indicating a set of SRS configurations associated with the logical channel; receiving, by the UE, an uplink grant indicating an uplink grant instance and an SRS configuration for the uplink grant instance; and selecting, by the UE, the logical channel to use resources of the uplink grant instance based in part on the set of SRS configurations and the SRS configuration for the uplink grant instance. Additional aspects are described.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communications and more specifically for handling hybrid automatic repeat request (HARQ) processes with discontinuous reception (DRX) operations. In some implementations, a user equipment (UE) may use a timer to maintain an ON duration in a DRX cycle based on receiving a downlink control information (DCI) message with a data-to-feedback timing indicator (for example, a K1 value) indicating a non-numeric value for a data message. For example, the UE may receive a DCI message with feedback timing for the data message based on maintaining the ON duration. In some other implementations, a UE may use a timer to maintain an ON duration following a feedback opportunity to support dynamic group-based HARQ messaging. For example, the UE may receive a DCI message requesting a retransmission of feedback information based on maintaining the ON duration.

Abstract: The present disclosure generally relates to techniques to increase reliability of communications within a network during a low reliability period. The network may include a user equipment (UE) communicatively coupled with one or more transmit/receive points (TRPs), with the communications between the UE and the one more TRPs requiring a reliability above a first reliability threshold. A processor of a network entity may identify a low reliability period which occurs when the reliability of the communications is determined to be below a second reliability threshold. The processor may cause the network to perform one or more remedial actions to increase the reliability during the low reliability period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink data communication. The UE may determine a processing time for the downlink data communication based at least in part on at least one of: whether the downlink data communication was scheduled via preconfigured scheduling or via a downlink grant received in a downlink control channel, or whether the downlink data communication is an initial transmission or a retransmission. The UE may transmit acknowledgement or negative acknowledgement (ACK/NACK) feedback, corresponding to the downlink data communication, using a timing indicated by the processing time. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that support group-based acknowledgment feedback techniques. Two or more different groups of downlink transmissions may each have an associated transport block (TB) level or code block group (CBG) level group-based acknowledgment feedback, and a base station may transmit downlink control information to a UE that indicates one or more parameters that are used to determine which downlink transmissions are to be reported in the group-based feedback at a TB level, CBG level, or combinations thereof. Based on the parameters in the downlink control information, the UE may determine the feedback to be reported, and a timing for when to transmit the feedback to the base station.

Abstract: In one aspect, a method of wireless communication includes receiving, by a mobile communication device during a first cycle, a periodic grant via a first carrier of a plurality of carriers, monitoring, by the mobile communication device during a next cycle after the first cycle, for configured grants (CGs) for multiple carriers of the plurality of carriers based on the periodic grant, and receiving, by the mobile communication device during the next cycle after the first cycle, a first transmission in a first CG of the CGs via a second carrier of the plurality of carriers and a second transmission in a second CG of the CGs via a third carrier of the plurality of carriers. Other aspects and features are also claimed and described.

Abstract: Cross-carrier operation control is disclosed. In a particular implementation, a method of wireless communication includes receiving, by a user equipment (UE), a channel via each entity of a plurality of entities. The method also includes combining, for the UE, the channel across the plurality of entities to generate a combined signal for decoding.

Abstract: Hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback codebook enhancements are disclosed. A size of feedback codebook may be reduced explicitly or implicitly. For example, an indicator may be identified by a corresponding field of a downlink control message. In some aspects, the indicator may indicate that multiple Physical Downlink or Uplink Shared Channels (PDSCHs/PUSCHs) are actually scheduled during one or more slots of a window corresponding to the feedback codebook. Responsive to receiving the indicator, a device may refrain from reducing the size of the feedback codebook to exclude acknowledgement feedback for additional possible PDSCH/PUSCH occasions of the slots of the window. In some aspects, a device identifies possible PDSCH/PUSCH occasions that occur outside of one or more Channel Occupancy Times (COTs) of a window. The device may generate a reduced size feedback codebook by excluding the possible PDSCH/PUSCH occasions that occur outside of the COTs of the window.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may communicate with a set of transceiver nodes (e.g., transmission reception points (TRPs)) in a first transceiver node operation mode (e.g., a multi-TRP mode). A first transceiver node of the set of transceiver nodes may receive, from a second of the set of transceiver nodes, an indication to switch between rate matching states. The first transceiver node may switch from a first rate matching state to a second rate matching state and may transmit a downlink shared channel based on a resource configuration associated with the second rate matching state. The UE may receive the shared channel based on an antenna port configuration determined by the UE based on the first transceiver node operation and rate matching information. The rate matching information may be provided by the first transceiver node.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently monitoring for wake-up signaling from one or more transmission and reception points (TRPs), the wake-up signaling indicating the presence of data or control information in an on-duration state of a discontinuous reception (DRX) cycle. In particular, select TRPs may be used to transmit wake-up signaling to a user equipment (UE), and the UE may be configured to monitor for wake-up signaling from the select TRPs. Once the UE receives wake-up signaling prior to an on-duration state of a DRX cycle from any of the select TRPs, the UE may then determine the TRPs scheduled to transmit data or control information in the on-duration state (e.g., based on the WUS or based on further control signaling), and the UE may receive the data or control information from the TRPs in the on-duration state.
