Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration message that indicates a radio resource allocation and a transmission scheme for one or more first configured grant-small data transfer (CG-SDT) occasions and one or more second CG-SDT occasions. The one or more second CG-SDT occasions are at least partially nested, in time, frequency, or a combination thereof, within the one or more first CG-SDT occasions. The UE may therefore transmit, to the base station, an uplink communication within the one or more first CG-SDT occasions or the one or more second CG-SDT occasions, using the radio resource allocation and the transmission scheme. Numerous other aspects are provided.

Abstract: A wireless device can flexibly switch between different frequency-division duplexing (FDD) modes including one or more half-duplex (HD) FDD modes and a full-duplex (FD) FDD mode in wireless communication. The wireless device can intelligently switch between the FDD modes to meeting different requirements of power consumption, traffic latency, and/or coverage enhancement.

Abstract: Apparatus, methods, and computer-readable media for managing HARQ-ACK processes in wireless user equipment (UEs) allow selective compression of HARQ-ACK information within HARQ-ACK codebooks. A wireless base station may transmit control information including scheduling information for K downlink transport blocks for a UE, and may signal bundling rules for selectively compressing an original HARQ-ACK codebook of size K into a constrained HARQ-ACK codebook of size N

Abstract: The present disclosure relates to procedures for random access channel (RACH) type selection and random access response (RAR) monitoring. Specifically, the present disclosure may configure a user equipment (UE) and network entity to perform RACH type selections, determine mapping ratios, perform mapping procedures for orphan PRACH resources, monitor one or multiple RAR messages within an extended RAR window, and facilitate RAR type differentiation.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling and bandwidth part (BWP) adaptation for extended reality (XR). A method that may be performed by a user equipment (UE) includes obtaining an indication to change at least one of a minimum control-channel-to-data-channel delay or a bandwidth for receiving a first transmission on a BWP; changing the at least one of the minimum control-channel-to-data-channel delay to a new minimum control-channel-to-data-channel delay or the bandwidth on the BWP to a new bandwidth; and receiving the first transmission on the BWP using the at least one of the new minimum control-channel-to-data-channel delay or the new bandwidth of the BWP.

Abstract: Methods, systems, and devices for wireless communications are described. One or more multiple access-capable user equipments (UEs) may be grouped together for transmitting uplink multiple access communications to a base station, where the UEs may be assigned to the group based on similar capabilities or service requirements. The UE may receive configuration information based at least in part on the group to which the UE has been assigned. When assigned to a group, the UEs may also receive a group-specific scrambling code for the uplink multiple access communications, a group-specific power control for the uplink multiple access communications, time and frequency resources to be used for the uplink multiple access communications specific to the group, or a combination thereof. Additionally, the specific time and frequency resources may be defined by multiple access resource units.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of scheduling information for dedicated on-demand system information (SI) corresponding to a specified UE category, wherein the indication is carried in at least one of: a minimum system information (MSI) communication, a radio resource control (RRC) message, a response message of a two-step random access channel (RACH) procedure, a random access response (RAR) message of a four-step RACH procedure, a contention resolution message of a four-step RACH procedure, a message type flag indicating the transmission of the dedicated on-demand SI, or a combination thereof; transmit, to the base station, an on-demand SI request based at least in part on the scheduling information and the UE category; and receive one or more on-demand system information blocks. Numerous other aspects are provided.

Abstract: Aspects described herein relate to physical downlink control channel (PDCCH) limits for multiple cells scheduling one cell in fifth generation new radio (5G NR). In an example, the aspects may include determining a PDCCH limit corresponding to at least one of a number of blind detections (BDs) and a number of control channel elements (CCEs) used for decoding PDCCH candidates for a first cell that schedules a second cell, and at least a third cell that schedules the second cell, wherein the third cell is the same cell as the second cell or the third cell is different from the second cell; and receiving one or more PDCCH transmissions from the first cell and the third cell based on the PDCCH limit.

Abstract: The present disclosure relates to methods and devices for wireless communication of an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may receive, from a base station, at least one SSB. The apparatus may also determine a RSRP of the at least one SSB. Additionally, the apparatus may transmit, to the base station if the RSRP of all of the at least one SSB is less than a threshold, an indication of a reduced UE capability of the UE during a RACH procedure. The apparatus may also transmit, to the base station if the RSRP of one of the at least one SSB is greater than or equal to the threshold, the indication of the reduced UE capability of the UE after entering into a RRC connected state upon completion of the RACH procedure.
