Abstract: Techniques providing opportunistic frequency switching for frame based equipment (FBE), such as may be configured to minimize opportunistic frequency switching delay in FBE new radio (NR) unlicensed (NR-U) networks and/or to provide frequency diversity FBE access based on offset sequences of medium sensing occasions for the carrier frequencies are disclosed. Within the FBE mode network, a base station may configure a pattern of sensing locations in each frame for each frequency transmission unit of the plurality of frequency transmission units, wherein an inter-unit delay of sensing locations between a first frequency transmission unit and a next adjacent frequency transmission unit and between a last frequency transmission unit and the first frequency transmission unit is a fixed duration. Opportunistic frequency switching of embodiments may utilize the medium sensing locations for opportunistically switching between a sequence of the frequency transmission units for implementing frequency diversity FBE access.

Abstract: This disclosure provides systems, methods and apparatus for aperiodic sounding reference signal (SRS) transmissions. In some aspects, a user equipment (UE) or a network entity may determine one or more time intervals for sounding reference signal (SRS) transmissions from a type of link, such as a link with another UE or a link with the network entity, used to communicate control signaling that triggers the SRS transmissions for the UE. A time interval in which the UE may not expect to transmit SRSs after receiving the control signaling, a time interval between the control signaling and the associated SRSs, a time interval between the control signaling and reception of one or more channel state information reference signals (CSI-RSs) used for precoding the SRSs, or any combination thereof, may be increased by an additional offset when the control signaling triggering the SRSs is received via the cooperative link.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to indicate to a base station a distribution of transmit antennas and receive antennas across a set of antenna panels, and the base station may configure resource sets for reference signal transmissions from the antenna panels based on the indicated distribution. In a first example, the UE may be configured to indicate a respective number of transmit antennas and receive antennas at each antenna panel. In a second example, the UE may be configured to indicate a sum of transmit antennas and a sum of receive antennas across all antenna panels, along with information on how the transmit antennas and receive antennas are distributed. Based on the indication, the base station may configure resource sets for reference signal transmission on sets of ports in resources of the resource sets.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. A user equipment (UE) may acquire a triggering synchronization signal block (SSB), which enables the UE to monitor for a floating Type-2 physical downlink control channel (PDCCH) and to determine a subset of paging occasions (POs) to monitor. Or, the UE may monitor for a fixed Type-2 PDCCH, where the UE does not require a triggering signal to monitors POs. In another aspect, the UE may monitor for a paging transmission during a monitoring period. The UE may determine the monitoring period based on received signaling. The UE may receive the signaling, during the monitoring period, indicating that the monitoring period is to be ended before a scheduled end of the monitoring period. In this way, the UE may support a continuity requirement associated with downlink reference signaling (DRS) and may support reception of paging in a shared channel.

Abstract: Control information may be transmitted for different TTI lengths. Different control information for the different TTIs may be transmitted using control channel resources that are established for communication of control information, such as a physical downlink control channel (PDCCH), for example. Control information for a first TTI may be located in a first set of resources, and control information for a second TTI may be located in a second set of resources. The first set of resources may be located within a first search space that may be searched by a user equipment (UE) to identify the first control information. The second set of resources may be located within a second search space that may be searched by the UE to identify the second control information.

Abstract: This disclosure provides systems, methods and apparatuses for a transmission, from a user equipment (UE) to a first distributed unit (DU), of one or more measurement reports including channel measurements of a set of cells associated with a second DU of a same central unit (CU) as the first DU. The UE may transmit the one or more measurement reports according to various reporting format options, including via separate reports for activated and deactivated cells of the second DU, a joint report for activated and deactivated cells of the second DU, or a joint report across a set of DUs including the first DU. The measurement reports may include one or more metrics associated with each cell of a configured cell set and the UE and the DUs of the same CU may activate or deactivate one or more cells for communication with the UE based on the measurement reports.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may cooperate with a second device to form a virtual device configured to communicate with a radio access network. The virtual device may appear as a single device from the perspective of the radio access network. Subsequently, a third device may be identified for replacing the second device within the virtual device. Based on the third device being identified, procedures for handing over communications from the second device to the third device may be executed. The procedures may include a beam management procedure, a random-access procedure, a mobility management procedure, or any combination thereof.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support separate hybrid automatic receipt request (HARQ) acknowledgement by member user equipments (UEs) cooperating as a virtual UE for downlink transmissions. In a first aspect, a virtual UE may detect a downlink transmission, wherein the virtual UE includes two or more member UEs in communication with each other and configured to cooperate in communications with the serving base station. The virtual UE may generate one or more acknowledgement codebooks configured to indicate an acknowledgement status by the virtual UE. The virtual UE may attempt to decode the downlink transmission and report an acknowledgment indicator that reflects the result of the decoding. The acknowledgment indicator includes an acknowledgement state selected from an acknowledgement codebook associated with the member UE. Other aspects and features are also claimed and described.
