Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a wakeup signal search space (WUS-SS) set for a physical downlink shared channel (PDCCH) wakeup signal (WUS). The UE may detect the PDCCH WUS in the WUS-SS set based at least in part on monitoring the WUS-SS set. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include transmitting a first signal instructing a user equipment (UE) to transition a state of a secondary cell associated with the UE; determining an allocation of resources for the UE to communicate with the secondary cell; and transmitting a second signal including an indication of an active bandwidth part (BWP) used for the allocation of resources based on the determining. The active BWP and the first signal may indicate the transition of the state of the secondary cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a mapping between synchronization signal blocks (SSBs) and a random access message of a two-step random access procedure based on an indication in system information signaling or radio resource control (RRC) signaling. The random access message may include a random access preamble and a random access payload. The UE may determine, based on the mapping, an association between one or more beams carrying the SSBs and one or more additional beams carrying the random access preamble and the random access payload of the random access message. As a result, the UE may perform the two-step random access procedure with a base station according to the beam association, and coexist with a four-step random access procedure in a more reliable and efficient manner.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support two different modes of operation (e.g., a normal transmission efficiency mode, a high transmission efficiency mode, etc.) either controlled by a network or the UE. The UE may transmit an indication of a capability of supporting the different modes of operation, where the network or the UE determine to use which mode of operation to use based on the transmitted capability. For example, the network may transmit an explicit indication of which mode of operation for the UE to use and/or may transmit an indication of the modes of operation, where the UE determines which mode of operation to use after receiving the indication. Additionally, the UE may determine which mode of operation to use based on being scheduled within or outside of a restricted bandwidth allocated to a mode of operation.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for efficient support of connected discontinuous reception (C-DRX) by using a wireless device (e.g., a user equipment (UE)) with a second receiver. A wireless device with two receivers may place one receiver in a low power mode and take the receiver out of the low power mode in response to a signal received from a serving base station (BS) of the wireless device. A BS may direct a wireless device to enter a low power DRX (LP-DRX) mode or enhanced DRX mode having longer low power cycles than a non-enhanced DRX mode, and the wireless device may place a primary receiver in a low power mode in response to the directive from the BS. Other aspects, embodiments, and features are also claimed and disclosed.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may monitor, in a first bandwidth part, of a plurality of bandwidth parts, associated with a first monitoring periodicity and in a downlink control channel, for a downlink control information (DCI) message. The user equipment may selectively transition, based at least in part on the DCI message, from the first bandwidth part to a second bandwidth part, of the plurality of bandwidth parts, associated with a second monitoring periodicity that is less than the first monitoring periodicity. Numerous other aspects are provided.

Abstract: Wake-up signal (WUS) downlink control information (DCI) may be configured to convey a wake-up indication as well as UE wake-up behavior configuration information. For example, WUS DCI may include one or more wake-up indications for one or more UEs via wake-up indication bits (e.g., wake-up indication bits may be conveyed in locations of the WUS DCI associated with monitoring indices of the one or more UEs to be activated). For example, WUS DCI may be encoded to include a wake-up indication and an indication of behavior configuration information for a group of one or more UEs. UE wake-up behavior configuration information may indicate some BWP to activate, may trigger a CSI report, etc. A UE may decode the wake-up indication and the wake-up behavior configuration information based on a monitoring index and the WUS configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish communications with a first base station and a second base station in accordance with a dual connectivity configuration. The UE may determine a second uplink timing gap for communications with the second base station and determine, based on being in the dual connectivity configuration, a first uplink timing gap for communications with the first base station. The first uplink timing gap may be determined to be greater than the second uplink timing gap. The UE may communicate with the first base station based on the first uplink timing gap. The UE may also prioritize uplink transmit power determinations for the first base station over uplink transmit power determinations for the second base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an uplink grant that includes multiple total downlink assignment indexes (DAIs) corresponding to multiple DAI groups associated with the UE, wherein each of the multiple DAI groups is associated with a different set of component carriers used by the UE for carrier aggregation; and transmit (ACK/NACK) feedback for the multiple DAI groups based at least in part on the multiple total DAIs included in the uplink grant. In some aspects, a base station may determine multiple total DAIs corresponding to multiple DAI groups associated with a UE, wherein each of the multiple DAI groups is associated with a different set of component carriers used by the UE for carrier aggregation; and transmit the multiple total DAIs to the UE in an uplink grant. Numerous other aspects are provided.
