Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a cell wake-up signal (WUS) indicating that a cell is to switch from operating according to a first mode to operating according to a second mode, the cell WUS including an indication of one or more communications to be transmitted by a network node associated with the cell during operation of the cell in the second mode.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may accumulate a number of hybrid automatic repeat request (HARQ) bits as a result of one or more resource conflicts and may store the number of HARQ bits for a later transmission opportunity. The UE may transmit a scheduling request that requests resources for a transmission of the number of HARQ bits that are stored at the UE as a result of the number of HARQ bits satisfying a triggering condition. For example, the UE may transmit the scheduling request if a quantity of the number of HARQ bits satisfies a threshold quantity. Additionally or alternatively, the UE may transmit the scheduling request if the number of HARQ bits include triggering content. For example, the UE may transmit the scheduling request if any HARQ bit stored at the UE conveys a negative acknowledgement (NACK).

Abstract: A UE may receive, from a base station, at least one downlink packet or at least one downlink packet retransmission. The UE may determine that a transmission of a HARQ feedback associated with the at least one downlink packet or the at least one downlink packet retransmission corresponds to a PUCCH collision. The UE may determine, based on the determination that the transmission of the HARQ feedback corresponds to a PUCCH collision, whether to delay the transmission of the HARQ feedback associated with the at least one downlink packet or the at least one downlink packet retransmission to a first available PUCCH occasion. The UE may cancel or delay the transmission of the HARQ feedback to the base station based on the determination whether to delay the transmission of the HARQ feedback.

Abstract: A user equipment (UE) may transmit, to a primary cell, an indication of a capability to synchronize with a secondary cell based on measurements of the primary cell. A UE may estimate a propagation delay (tp) and an angle of arrival (AoA) of the secondary cell based on a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) transmitted by the primary cell. A UE may perform automatic gain control (AGC), fine timing synchronization, and fine frequency synchronization of the secondary cell based on a temporary aperiodic tracking reference signal (A-TRS) transmitted by the secondary cell. A UE may perform a receive beam sweep on a burst of a CSI-RS transmitted by the secondary cell, wherein a range of the receive beam sweep is based on the estimated AoA.

Abstract: Aspects of the present disclosure allow a UE to request, in an anchor carrier on one frequency band, a base station to configure and transmit A-TRS in an SSB-less secondary carrier on a different frequency band. The UE transmits, in a first cell served by the anchor carrier, a request for A-TRS. Based on the request, the UE receives, in a second cell lacking SSB transmissions served by the secondary carrier, the A-TRS based on the request. The base station may also control transmission of the A-TRS in the SSB-less secondary cell based on a timer derived from the request. Using the A-TRS, the UE may apply AGC and time/frequency tracking loop operations prior to receiving a PDSCH in the SSB-less secondary cell, thereby improving reception performance of downlink data transmissions in the secondary carrier. Thus, network energy savings provided by SSB-less secondary carriers may be obtained in inter-band CA.

Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for performing and reporting suitable measurements, at a first user equipment (UE), on reference signals from relay UEs to determine which relay UEs to activate or deactivate for relaying communications for the first UE. The first UE may be configured to perform measurements on deactivated relay UEs, and the first UE may report these measurements (or other measurements) when one or more events are triggered. The events may depend on the measurements performed on the deactivated relay UEs. Once the events are triggered, the first UE may report the measurements, and a second UE or a network entity may use the measurements to efficiently determine which relay UEs to activate or deactivate for relaying communications for the first UE.
