Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit UE assistance information including UE capability report and measurement report to a base station, and the base station may determine a physical downlink control channel (PDCCH) monitoring configuration for reduced-capability UEs based at least in part on the UE assistance information. The UE may determine whether a group common PDCCH (GC-PDCCH) communication indicates that the zone identifier is activated for an associated monitoring period. The UE may selectively perform one or more PDCCH blind decodes in one or more search space sets associated with the zone identifier during the monitoring period based at least in part on determining whether the GC-PDCCH communication indicates that the zone identifier is activated for the monitoring period. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate an uplink control information (UCI) message including a first UCI bit multiplexed with a second UCI bit, the first UCI bit having a first sequence applied and the second UCI bit having a second sequence, that is orthogonal to the first sequence, applied. The UE may transmit the UCI message. Numerous other aspects are described.

Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals are provided. In one aspect, a method of wireless communication performed by a user equipment (UE), includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell, and receiving, from the BS via the second cell during an activation period, a first reference signal different from a synchronization signal block (SSB). The method further includes performing a measurement of the first reference signal, and operating in the second cell based on the measurement. In some aspects, using reference signals different from SSBs may reduce the delay associated with activating the secondary cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive information indicating a reservation or allocation of a resource for transmission of a first signal by another network node, wherein the information identifies whether the network node is to use the resource for transmission of a second signal concurrently with the first signal. The network node may transmit the second signal in the resource based at least in part on the information identifying whether the network node is to use the resource for transmission of the second signal. Numerous other aspects are described.

Abstract: Aspects of the disclosure relate to obtaining a duplex mode of a scheduled entity, selecting a downlink-uplink (DU) slot interpretation to be applied by the scheduled entity to a slot including a DU symbol based on the duplex mode of the scheduled entity, and transmitting the DU slot interpretation to the scheduled entity. The DU symbol may be configured to include a downlink transmission and an uplink transmission within a same carrier bandwidth. Other aspects relate to receiving a message, indicating that the slot is formatted with a DU symbol, selecting a DU slot interpretation to be applied to the slot including the DU symbol based on a duplex mode of the scheduled entity, and applying the DU slot interpretation to the slot. Other aspects, examples, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication of whether the UE is capable of using a virtual port to transmit uplink communications using a maximum transmit power according to a power class of the UE. The virtual port may be a combination of one or more antenna ports. The indication may be based at least in part on an operating mode of the UE. The UE may receive, from the base station, a sounding reference signal configuration based at least in part on the indication. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may perform channel state information (CSI) estimation on multiple links (e.g., a Uu link and a sidelink) without excessive power expenditures. The UE may report a CSI processing unit (CPU) capability to a network device. The CPU capability information may include separate CPU capabilities for separate links, or a single CPU capability for multiple links. The network device, the UE, or both, may trigger CSI estimation procedures that do not exceed the reported CPU capability, or may otherwise prioritize CSI estimation procedures based on the CPU capability. The UE may then perform CSI estimation procedures according to one or more rules associated with the CPU capabilities. In some examples, such rules may be explicitly signaled to the UE, or may be included in one or more standard documents.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive at least one control message from a base station, the at least one message jointly scheduling the UE for access network communications between the UE and the base station and for sidelink communications between the UE and another UE, such as another UE in a group of UEs. The UE may determine network control information based on the at least one control message. The UE may also determine sidelink control information based on the at least one control message. The UE may communicate with the base station and the other UE in accordance with the network control information and the sidelink control information, respectively.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may dynamically and reliably indicate that pending transmissions are part of a full duplex operation via downlink control information (DCI) designs described herein. For example, a base station may transmit, to a user equipment (UE) a DCI including no more than one downlink grant and no more than one uplink grant for a full duplex operation. In some examples, the base station may transmit a first-stage DCI including partial information, and second-stage DCIs including full uplink and downlink grants for a full duplex operation. In some examples, the base station may configure periodic or semi-periodic uplink and downlink resources that may overlap in time, and may dynamically indicate, to the UE, whether the overlapping uplink and downlink resources are scheduled for a full duplex operation.

Abstract: Certain aspects of the present disclosure provide techniques for reducing a size of semistatic codebooks for HARQ feedback. A method that may be performed by a user equipment (UE) includes determining a number (M) of candidate downlink transmission occasions for a time period, determining a maximum number (k) of simultaneous downlink transmissions the UE can receive during the time period, receiving one or more downlink transmissions during the time period from a base station, and determining a type of encoding for the HARQ feedback based on: (i) a number of the one or more downlink transmissions received, (ii) the number (M) of candidate downlink transmission occasions for the time period, and/or (iii) the maximum number (k) of simultaneous downlink transmissions.
