Abstract: Wireless communication devices, systems, and methods related to handling wake-up behavior for power saving, including during discontinuous reception (DRX) operation are provided. For example, a method of wireless communication includes transmitting, by a base station (BS) to a user equipment (UE), a default wake-up configuration associated with a discontinuous reception (DRX) operation; determining, by the BS, whether to transmit a wake-up signal (WUS) to the UE during a WUS occasion based on a traffic load; and transmitting, by the BS, a physical downlink control channel (PDCCH) signal during a duration associated with the WUS occasion.

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, configuration information for a physical downlink control channel (PDCCH) associated with single frequency network (SFN) transmissions and PDCCH repetitions, wherein the configuration information indicates a first control resource set (CORESET) and a second CORESET, wherein the first CORESET is associated with a first transmission configuration indicator (TCI) state and the second CORESET is associated with a second TCI state. The UE may receive, from the base station and based at least in part on the reception of the configuration information, at least one of one or more SFN PDCCH messages or one or more PDCCH repetitions. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described to support determination of an uplink beam for uplink transmissions. A base station may configure a user equipment (UE) with multiple sets of sounding reference signal (SRS) resources that may be used for uplink transmissions from the UE. In some cases, each set of SRS resources may be configured with one associated channel state information reference signal (CSI-RS) resource, and each CSI-RS resource may correspond to an uplink beam. The base station may transmit a downlink control message to the UE, indicating one or more selected SRS resource sets and one or more selected SRS resources within each of the one or more selected SRS resource sets. The UE may transmit an uplink transmission with a beam associated with the indicated SRS resource set.

Abstract: Wireless communications systems and methods related to wireless communications in a system are provided. A user equipment (UE) may receive from a base station (BS), an uplink (UL) scheduling grant indicating subband precoding information and a resource allocation spanning a plurality of subbands. The UE may determine a plurality of subband precoders based on the subband precoding information. Each precoder of the plurality of subband precoders may be associated with a subband of the plurality of subbands. The UE may transmit to the BS, an UL communication signal in the resource allocation using the plurality of subband precoders.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a first configuration for a first sounding reference signal (SRS) set and a second configuration for a second SRS set, the first SRS set to be transmitted using a first group of antennas of the UE and the second SRS set to be transmitted using a second group of antennas of the UE; determine a size of a downlink control information (DCI) field to be included in an uplink DCI communication scheduling a physical uplink shared channel (PUSCH) transmission, the DCI field to indicate a selected SRS set; receive the uplink DCI communication scheduling the PUSCH transmission; and identify the selected SRS set based at least in part on the determined size of the DCI field and information carried in the DCI field. Numerous other aspects are provided.

Abstract: An UE transmits at least one UE configuration parameter to a base station comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The UE then receives a configuration from the base station based, at least in part, on the at least one UE configuration parameter transmitted to the base station. Additionally, a base station receives the at least one UE configuration parameter from a UE comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The base station then configures the UE using the at least one UE configuration parameter received from the UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines a configuration of a common PUCCH resource set that is based on a frequency hopping pattern and includes a first set of resource blocks (RBs) of a bandwidth part (BWP) in a first group of symbols and a second set of RBs of the BWP in a second group of symbols. In some designs, the second set of RBs is offset in frequency from the first set of RBs by a fixed hopping distance. In other designs, the BWP is further associated with a second PUCCH resource set that includes a third set of RBs of the BWP that overlaps in part with the first set of RBs of the BWP in the first group of symbols, a fourth set of RBs of the BWP that overlaps in part with the second set of RBs of the BWP in the second group of symbols, or a combination thereof.
