Abstract: Information is communicated via a plurality of communication opportunities of a semi-persistent scheduling (SPS) occasion. A base station may transmit first information via a first communication opportunity of an SPS occasion and transmit second information via a second communication opportunity of that same SPS occasion. A wireless communication device may monitor all communication opportunities of an SPS occasion to decode the information sent in two or more of the communication opportunities of the SPS occasion.

Abstract: This disclosure provides systems, methods and apparatus for cellular communications. In one aspect, a UE determines an FFP of a cell signal for the UE in a frame based equipment mode, determines one or more SSB positions in the cell signal based on the FFP, and performs radio management of the UE based at least in part on the one or more invalid SSB candidate positions. Performing radio management may include using one or more SSB positions in the FFP exclusive of the one or more invalid SSB candidate positions. Radio management may include PDSCH rate matching, radio link monitoring or measurement, or radio resource management. In some implementations, the one or more SSB positions are SSB positions after a first eight SSB positions in an FFP. In some other implementations, the one or more SSB positions are SSB positions that at least partially overlap an idle period between FFPs.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include receiving, from a base station (BS), a resource pool (RP) configuration that indicates resources in a licensed frequency band reserved for sidelink control information (SCI), transmitting, to a second sidelink UE, the SCI in the reserved resources, wherein the SCI includes a starting position of channel occupancy time (COT) resources in an unlicensed frequency band, and transmitting, to the second sidelink UE, a physical sidelink shared channel (PSSCH) via the COT resources in the unlicensed frequency band.

Abstract: A method for wireless communications is presented. The method may be performed by a user equipment (UE) and includes receiving a multi-user physical (MUP) downlink shared channel (PDSCH) communication (MUPC) comprising a number of payloads. The method also includes transmitting an acknowledgement (ACK) in response to decoding the MUPC. The method further includes receiving a message requesting retransmission of at least one payload of the number of payloads. The method still further includes transmitting the at least one payload in response to the message.

Abstract: Aspects of the disclosure relate to transport block (TB) scaling in the physical uplink shared channel (PUSCH) and physical downlink shared channel (PDSCH) for select frequency bands, such as new radio unlicensed (NR-U) bands where the allowed power spectral density may be lower.

Abstract: Certain aspects of the present disclosure provide techniques for determining which of two or more invalid symbol patterns to apply to at least one physical uplink shared channels (PUSCHs) with repetition, such as in a multi-transmit-receive-point (multi-TRP) situation where two or more invalid symbol patterns may be used to schedule respective PUSCHs. For example, a pattern may indicate one or more invalid symbols for PUSCH repetition Type B transmission. In a multi-TRP case, each TRP may have a separate pattern indicating different unavailable symbols. One invalid symbol pattern may not be enough for PUSCH transmissions to multi-TRPs. The present disclosure provides techniques for determining and applying one or more of at least two patterns to PUSCH transmissions with repetition.

Abstract: A communication configuration is selected based on the bandwidth used by a wireless communication device during a random access procedure (e.g., on an unlicensed band). In some scenarios, the maximum transmit power that the wireless communication device can use may be significantly restricted (e.g., by a regulation). In some cases (e.g., when the wireless communication device is near a center of a cell), the wireless communication device may transmit the random access information using a default bandwidth. In other cases (e.g., when the wireless communication device is near a cell edge), the wireless communication device may transmit the random access information using a wider bandwidth (e.g., to increase the coverage of the transmission). In some aspects, the maximum bandwidth used for the random access procedure may be used to select at least one communication configuration that is used for a subsequent communication (e.g., data or control signaling).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may encode, for a first set of resource elements (REs), a first layer for sidelink control information. The UE may encode, for a second set of REs, a second layer for sidelink data, wherein the first set of REs and the second set of REs are associated with a same one or more symbols. The UE may transmit, to another UE and based at least in part on applying superposition coded modulation (SCM) to the first layer and the second layer, the sidelink control information using the first set of REs and the sidelink data using the second set of REs. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, on a physical uplink channel, repetitions without a demodulation reference signal (DMRS). The UE may maintain continuity for joint channel estimation of the repetitions without a DMRS during a first time domain window that is based at least in part on a second time domain window associated with joint channel estimation for repetitions with a DMRS. Numerous other aspects are described.
