Abstract: Wireless communication systems and methods related to random access in a wireless communication network are provided. A user equipment (UE) receives a configuration indicating a random access preamble for a random access associated with multiple random access occasions (ROs). The UE transmits the random access preamble in one or more of the multiple ROs. The UE determines one or more random access-radio network temporary identifiers (RA-RNTIs) for the multiple ROs. The UE monitors for a random access response (RAR) message based on the one or more determined RA-RNTIs in a RAR window associated with the multiple ROs.

Abstract: Methods, apparatuses, and computer-readable storage medium for conditional handover (CHO) are provided. An example method at a UE may include receiving, from a first base station, a CHO configuration comprising one or more CHO candidate cell configurations associated with a second base station and one or more execution conditions associated with the first base station and including one or more CHO measurements, the one or more CHO measurements comprising one or more L1 beam or cell specific measurements or one or more L3 beam specific measurements. The example method may further include detaching from a first cell associated with the first base station and synchronizing with a second cell associated with the second base station based on the one or more CHO measurements satisfying the one or more execution conditions, the second cell being one cell associated with the one or more CHO candidate cell configurations.

Abstract: A communication configuration is selected based on the bandwidth used by a wireless communication device during a random access procedure (e.g., on an unlicensed band). In some scenarios, the maximum transmit power that the wireless communication device can use may be significantly restricted (e.g., by a regulation). In some cases (e.g., when the wireless communication device is near a center of a cell), the wireless communication device may transmit the random access information using a default bandwidth. In other cases (e.g., when the wireless communication device is near a cell edge), the wireless communication device may transmit the random access information using a wider bandwidth (e.g., to increase the coverage of the transmission). In some aspects, the maximum bandwidth used for the random access procedure may be used to select at least one communication configuration that is used for a subsequent communication (e.g., data or control signaling).

Abstract: A network access node including a transceiver coupled to a sidelink receiver user equipment (UE) (or to a sidelink transmitter UE) is disclosed. The network access node may obtain a network access interface discontinuous reception (DRX) slot offset value (or a sidelink interface DRX slot offset value) corresponding to a shift in a network access interface DRX Active state start time (or a sidelink interface DRX Active state start time) of the receiver UE. The shift may configure an alignment of a sidelink interface DRX Active state start time (or the network access interface DRX Active state start time) with the network access interface DRX Active state start time (or the sidelink interface DRX Active state start time). The network access interface DRX (or sidelink interface DRX) slot offset value may be transmitted to the receiver UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may detect that an antenna of a second wireless communication device is to perform a channel sensing procedure on a channel during a time occasion. The first wireless communication device may transmit, during the time occasion in one or more directions other than a direction of the antenna of the second wireless communication device, a signal that satisfies an energy detection threshold. Numerous other aspects are described.

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: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for dynamically updating a set of cells activated to serve a user equipment (UE) and synchronizing with the cells activated to serve the UE. An example method generally includes receiving, from a network entity, signaling indicating a set of cells supported by one or more distributed units (DUs) under a common central unit (CU) and one or more timing advance groups (TAGs) for the set of cells; identifying a subset of the set of cells activated to serve the UE; receiving physical (PHY) layer or medium access control (MAC) layer mobility signaling; updating the subset of activated cells based on the mobility signaling; and communicating with the subset of activated cells based on a timing advance associated with the one or more TAGs in which the updated subset of activated cells belong.
