Abstract: This disclosure relates to transferring data segments, and includes a method and apparatus for performing a random access channel (RACH) procedure with a network entity for transferring a first portion of a plurality of data segments from a user equipment (UE) to the network entity during a radio resource control (RRC) inactive state, wherein the RACH procedure comprises receiving a physical downlink control channel (PDCCH) configuration from the network entity, the PDCCH configuration including an identified search space; and monitoring a PDCCH for PDCCH candidates addressed by a UE-specific network identifier in the identified search space for dynamic scheduling information that schedules a second portion of the plurality of data segments.

Abstract: Aspects relate to sending a transmission control indicator (TCI) state activation in a multiple transmission and reception point (multi-TRP) transmission system having multiple component carriers. A component carrier (CC) list of component carrier identifiers (IDs) may be configured to either exclude or include a select CC ID prior to sending a transmission configuration indicator (TCI) state activation within control signaling to at least one user equipment (UE) in the RAN. Depending on whether the CC ID is excluded or included in the CC list, the receiving UEs in the system may be configured to apply a TCI state activation for the CC ID either included or excluded in the CC list, or not apply any TCI state to any CC ID by ignoring the control signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may encode, at a layer two (L2) layer of the transmitting device, a set of service data units (SDUs) according to a set of network coding parameters to obtain a first set of protocol data units (PDUs). The transmitting device may transmit, to one or more receiving devices, the first set of PDUs. The transmitting device may receive, from a receiving device of the one or more receiving devices, a report indicating an SDU of the set of SDUs that was unsuccessfully received at the receiving device. The transmitting device may transmit, to the one or more receiving devices, based at least in part on the received report, a second set of one or more PDUs corresponding to at least the SDU of the set of SDUs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, in an inactive state, that uplink data is to be transmitted. The UE may determine whether a timing advance of the UE is valid. The UE may, if the timing advance is not valid, determine whether the uplink data satisfies a transport block size (TB S) threshold. The UE may, based at least in part on whether the uplink data satisfies the TB S threshold, selectively transmit the uplink data via an uplink random access channel (RACH) message or a configured uplink resource, or establish a radio resource control (RRC) connection for the uplink data. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for quasi-colocation (QCL) assumptions, such as QCL assumptions for combined single-DCI (downlink control information) and multi-DCI mTRP (multiple transmission reception point) scenarios. A method that may be performed by a user equipment (UE) includes receiving signaling configuring the UE with a first index value associated with a first plurality of control resource sets (CORESETS) and a second index value associated with a second plurality of CORESETS. The UE may receive at least one medium access control (MAC) control element (CE) that activates a set of transmission configuration indicator (TCI) states, indicates one of the first or second index values, and that maps at least one TCI codepoint in downlink control information (DCI) to two TCI states. The UE may determine one or more TCI states to use for receiving one or more transmissions based, at least in part, on the mapping.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, configuration information related to a random access procedure. For example, in some aspects, the configuration information may include a physical random access channel mask configuration based at least in part on a random access occasion density in a time and frequency domain in a cell served by the base station, a random access response configuration based at least in part on an indication transmitted from the UE to the base station, and/or the like. Accordingly, the UE may perform the random access procedure based at least in part on the configuration information, which may be indicated to the UE in system information, radio resource control signaling, and/or the like. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability report to a base station indicating a triggering offset. The base station may configure the UE with one or more channel state information (CSI) measurement resources and send downlink control information (DCI) that triggers an aperiodic CSI report for some of the CSI measurement resources. The UE may report CSI by measuring the CSI resources after the triggering offset. In some cases, CSI reporting related to the different codebook types (e. g., Type I, Type II) may be modified, where after identifying a type of codebook and determining which type of codebook to process (e. g., based on a number of CSI processing units), the UE may identify a priority associated with different CSI reports. The UE may be configured with various parameters that relax or modify the processing of Type II CSI reports.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may detect a trigger to initiate determination of a performance parameter for a packet data convergence protocol (PDCP) duplication procedure associated with a PDCP instance. The wireless communication device may receive packets of the PDCP instance via multiple radio link control (RLC) entities according to the PDCP duplication procedure. The wireless communication device may determine the performance parameter based at least in part on whether packets of the PDCP instance are successfully received via one or more RLC entities of the multiple RLC entities. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a report for one or more two-step random access channel (RACH) procedures between the UE and a base station (BS), wherein the RACH report includes at least one of an indication of a quantity of message A (MsgA) payloads transmitted during the one or more two-step RACH procedures on each beam of one or more beams associated with the BS, an indication of one or more parameters associated with each MsgA communication transmitted during the one or more two-step RACH procedures, or an indication of whether a respective signal strength for each beam, associated with the one or more two-step RACH procedures, satisfies a signal strength threshold. The UE may transmit the report to the BS. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may configure a physical downlink control channel (PDCCH) component of a message B (msgB) communication to include a first portion of the signaling information for physical uplink control channel (PUCCH) for hybrid automatic repeat request (HARQ) feedback associated with the msgB communication and the signaling information for HARQ combining of msgB. The BS may configure a physical downlink shared channel (PDSCH) component of the msgB communication to include a second portion of the signaling information for PUCCH and msgB HARQ combining. The distributed mapping for the signaling information to the PDCCH and PDSCH components of msgB can be indicated by system information, RRC signaling, or hard coded in specifications. The BS may transmit the msgB communication to one or more UEs. Numerous other aspects are provided.
