Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of resource parameters for performing sounding reference signal transmissions during a slot comprising at least one subband full-duplex symbol and at least one non-subband full-duplex symbol. The UE may perform multi-symbol sounding reference signal transmissions during the slot according to a transmission scheme associated with the resource parameters, the transmission scheme defining a transmit or drop rule based on a first subset of sounding reference signal transmissions being scheduled in the at least one subband full-duplex symbol of the slot and a second subset of sounding reference signal transmissions being scheduled in the at least one non-subband full-duplex symbol of the slot.

Abstract: Aspects presented herein may enable a base station to perform demodulation reference signal (DMRS)-based channel sounding for a channel between the base station and a UE, such that the base station may configure a more suitable precoding for coherent UL multiple input multiple output (MIMO) transmission(s) of the UE without increasing communication overhead significantly or at all. In one aspect, a base station performs channel sounding for a channel based on a set of physical uplink shared channel (PUSCH) DMRS received from a UE via the channel. The base station selects a precoding to be used by the UE for a subsequent PUSCH transmission via the channel based on the channel sounding. The base station transmits, for the UE via a physical downlink control channel (PDCCH), a transmit precoder matrix indicator (TPMI) indicating the selected precoding, where the PDCCH schedules the subsequent PUSCH transmission for the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a set of repetitions of a preamble message, wherein the preamble message is a portion of a first random access channel (RACH) message of a RACH procedure. The UE may receive a random access channel response (RAR) message in an RAR window of the RACH procedure, wherein the RAR window is included in a set of RAR windows for monitoring for the RAR message, and wherein at least one RAR window, of the set of RAR windows, starts after transmission of a first repetition, of the set of repetitions, and before transmission of a last repetition of the set of repetitions. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein support transmission of a transport block over multiple slots (TBoMS) with subband full duplex (SBFD) operation. For example, if a time domain resource allocation for a TBoMS includes both uplink slots and downlink slots configured with an uplink subband, a user equipment (UE) may determine which slots to use in accordance with a scheme for selecting available slots for the TBoMS from indicated candidate slots, and the UE may determine the transport block size based on the selected slots. In some examples, the UE may first determine the quantity of resource elements available in each of the different slot types, and then may determine the transport block size based on the quantity of resource elements available in each of the different slot types and the quantity of each of the different slot types.

Abstract: A user equipment (UE) receives a configuration of a first plurality of subbands having different sizes for channel state information (CSI) reporting. The configuration is for a bandwidth part configured for subband full duplexing with an uplink subband. A size of the subbands in the first plurality of subbands decreases closer in frequency to the uplink subband. The UE transmit a reduced CSI report payload including a plurality of CSI values, the reduced CSI report payload having fewer bits than a size of an absolute CSI value times a number of subbands in the first plurality of subbands. The UE may reduce the number of bits in the CSI report payload using differential CSI values instead of absolute CSI values, reporting CSI values for only a subset of the subbands, or using a fallback subband configuration with equal sized subbands.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of one or more sidelink resources, and the UE may identify wake-up signal occasions associated with the resources. The UE may monitor for wake-up signals during the wake-up signal occasions, and the UE may further monitor the associated set of one or more resources based on receiving a wake-up signal. In some examples, respective sets of one or more sidelink resources may be associated with a number of multiple-input multiple-output layers used for sidelink communications, or may indicate respective bandwidth parts used for monitoring sidelink transmissions.
