Abstract: A new radio (NR) bit prioritization procedure that may be executed by a UE and a base station is disclosed, resulting in transmission and reception of modulation symbols having prioritized bits. For example, a transmitter may encode a code block using low-density parity-check code to generate a stream of encoded bits. The transmitter may arrange the encoded bits in one or more modulation symbols according to a relative priority of the encoded bits. The highest priority bits may be located in the most significant bits of the modulation symbol, and therefore be less likely to experience errors. A receiver may receive the modulation symbols and reorder the encoded bits according to the coding scheme based on the relative priority prior to decoding the encoded bits. The prioritization of the bits within the modulation symbols may provide improved block error rates over sequential mapping of encoded bits to symbols.

Abstract: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability information message indicating a timeline prior to a physical uplink shared channel (PUSCH) occasion that the UE may be capable of transmitting a PUSCH skipping indication. The PUSCH skipping indication may indicate that the UE may skip uplink transmission in at least one PUSCH occasion. In some cases, the UE may receive signaling indicating that the UE is scheduled with one or more PUSCH occasions. The UE may transmit, at least at the indicated timeline to a first PUSCH occasion, a control message including the PUSCH skipping indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Various aspects relate generally to anchor cell management for a synchronization signal block (SSB)-less secondary cell (SCell). In some aspects, an anchor cell in a different frequency band from an SSB-less SCell may be used for downlink beam management of the SSB-less SCell. A UE may report, to a network node, reference signal received power (RSRP) measurements for a plurality of downlink reference signals transmitted via the anchor cell, and the network node may determine a downlink beam for the SSB-less SCell based at least in part on the RSRP measurements. The UE may receive a configuration of the SSB-less SCell, and the configuration may indicate the anchor cell associated with the SSB-less SCell. The UE may receive an activation indication that activates the SSB-less SCell for the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A UE capability for a multiple physical downlink shared channel (PDSCH) scheduling may be signaled from a UE to a network entity. A UE capability signaling may indicate whether the UE supports a multiple PDSCH scheduling being associated with a same time domain resource allocation (TDRA) and/or a same frequency domain resource allocation (FDRA). The network node may schedule the multiple PDSCHs, via a multiple user multiple-input multiple-output (MU-MIMO) PDSCH scheduling or a multiple downlink control information (multi-DCI) multiple transmission reception point (mTRP) PDSCH scheduling, based at least in part on the UE capability signaling. The network entity may guarantee that co-scheduled PDSCHs have the same TDRA and/or the same FDRA, which may be based at least in part on the UE capability signaling.

In some aspects, a user equipment (UE) may transmit, to a network node and via a buffer status report (BSR) or scheduling request (SR), a request indicating one or more parameters associated with sidelink communications in an unlicensed spectrum. The UE may receive, from the network node, a sidelink resource allocation indicating one or more resource block (RB) sets associated with the unlicensed spectrum. The UE may transmit, to a sidelink UE and based at least in part on the sidelink resource allocation and on a result of performing listen-before-talk (LBT), a sidelink communication. Numerous other aspects are described.
