Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a first slot for a semi persistent scheduled (SPS) transmission on a first serving cell of multiple serving cells in a physical uplink control channel (PUCCH) group. The UE may be configured to transmit feedback information for the SPS transmission in a target slot. The UE may select either the target slot or a subsequent second slot for transmission of the feedback information based on an availability of uplink resources on the multiple serving cells in the target slot. The UE may transmit the feedback information to a base station in the target slot or the subsequent second slot based on the selection. The described techniques may enable the UE to transmit the feedback information with reduced latency, among other benefits.

Abstract: A method of wireless communication, by a user equipment (UE), includes receiving, from a network device, a trigger command initiating a hash-based random access procedure. The trigger command includes a target hash value and one or more rules for selecting preambles. The method also includes selecting, based on the trigger command, one or more random access channel (RACH) occasions (RO) for potential preamble transmission. The method further includes calculating at least one hash value in response to the trigger command based on computational resources of the UE. The method also includes transmitting a preamble on the at least one selected RO based on the at least one hash value and the target hash value.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity (e.g., a base station or reader) may transmit an initial access trigger message (e.g., modulating a continuous wave transmission using amplitude shift keying (ASK)), and the trigger message may include an indication of a type of passive user equipment (PUE) or a PUE use case (e.g., high priority/latency-critical PUEs or low priority/latency non-critical PUEs). A receiving PUE may harvest energy from the initial access trigger message for transmitting an initial access response message including an identifier for the receiving PUE. The receiving PUE may transmit the initial access response message (e.g., on one or more initial access resources) using the harvested energy if the trigger message indicates the PUE's type of PUE or PUE use case. In some examples, the receiving PUE may ignore triggers for different types of PUEs or PUE use cases.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, a downlink message associated with a first random access channel (RACH) procedure between the network entity and the UE, the downlink message including an accessibility indicator of a first cell supported by the network entity, the accessibility indicator indicating whether the first cell is inactive at a future time period. The UE may perform one of the first RACH procedure for the first cell based at least in part on the accessibility indicator indicating that the first cell supported by the network entity is active at the future time period or a second RACH procedure for a second cell based at least in part on the accessibility indicator indicating that the first cell supported by the network entity is inactive at the future time period.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may transmit feedback, such as hybrid automatic repeat request (HARQ) feedback for groups of code blocks rather than for an entire transport block or individual code blocks. The wireless device may transmit an acknowledgement (ACK) or negative-acknowledgement (NACK) to provide feedback for each code block group of a set of code block groups. An ACK may indicate that code blocks in a code block group were successfully decoded, and a NACK may indicate that at least one code block in a code block group was not successfully decoded. Wireless devices may support several techniques for grouping code blocks for feedback reporting to allow for efficient retransmissions and limited overhead. Different grouping schemes may be employed depending on system constraints, device capability, link conditions, or the like.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating cell discontinuous reception (DRX) or discontinuous transmission (DTX) cycles for multiple transmission reception points (TRPs). The cell DRX or DTX cycles may indicate inactive times and active times for the multiple TRPs. The UE may communicate with one or more TRPs, of the multiple TRPs, in accordance with the cell DRX or DTX cycles. Numerous other aspects are described.

A network entity may identify at a first cell of the network entity, an energy savings configuration for a set of cells associated with the network entity. The energy savings configuration may include a respective discontinuous transmission (DTX) activation state for one or more cells of the set of cells, a discontinuous reception (DRX) activation state for the one more cells of the set of cells, or both. The network entity may transmit, to a set of user equipments (UEs), control signaling that indicates an energy savings activation state for the one or more cells of the set of cells based on the energy savings configuration. The network entity may communicate, via the set of cells, with one or more UEs of the set of UEs in accordance with the energy savings activation state.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a control message indicating a channel state information (CSI) reporting configuration for a subband full-duplex (SBFD) slot. The CSI reporting configuration may indicate that the UE is to report CSI for entire bandwidths of respective downlink subbands of the SBFD slot. That is, the CSI reporting configuration may configure the UE for per-downlink subband CSI reporting. The UE may receive CSI reference signals via the downlink subbands, and measure CSI for the reference signals. The UE may transmit, according to the CSI reporting configuration, a CSI report indicating the CSI for the downlink subbands. In some examples, the CSI may include some combination of channel quality indicators (CQIs) and precoding matrix indicators (PMIs).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) switch between carriers of a group of a carriers during uplink communications in accordance with a mapping. For example, the UE may report its capability to a base station for switching between carriers of the group, where the group includes a supplementary uplink (SUL) carrier and two or more normal uplink (NUL) carriers that are each associated with a different radio frequency band. The base station may indicate for the UE to switch to a subset of carriers of the group corresponding to a combination of radio frequency bands for transmission of an uplink message. The UE may switch to at least one carrier of the subset of carriers in accordance with a mapping that is based on the reported capability and may transmit the uplink message on the at least one carrier.

Abstract: Mechanisms for cross-carrier scheduling from a first cell to a second cell in a wireless networking scheme are provided. In one aspect, a method includes receiving, from a base station (BS), a first configuration for scheduling in a first cell having a first subcarrier spacing (SCS), wherein the first configuration is associated with a first search space in the first cell. The method further includes receiving, from the BS, a second configuration for scheduling in the first cell, wherein the second configuration is associated with a second search space in a second cell, and wherein the second cell is associated with a different second SCS. The method further includes determining a number of blind detections (BDs) based on at least one of the first SCS or the second SCS, and monitoring, based on the number of BDs, for downlink control information (DCI) in the first and second search spaces.
