Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit (RU) may receive, from a distributed unit (DU), a control plane message associated with a section type that is dedicated for information that applies to all resource blocks and spatial layers in a group of carriers or band sectors, wherein the control plane message includes information that applies to all resource blocks and spatial layers in an indicated group of carriers or band sectors. The RU may perform beamforming for one or more communications with a user equipment (UE) based at least in part on the information included in the control plane message. Numerous other aspects are described.

A method of operating a network node (120) of a communications network (100) comprises obtaining (1101) one or more positioning conditions of a wireless communication device (130), and selecting (1102) a positioning reference signal resource allocation for positioning reference signals (150) from a set of positioning reference signal resource allocations based on the one or more positioning conditions of the wireless communication device (130).

A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of a physical random access channel (PRACH) over physical resource blocks (PRBs) that are interlaced in an unlicensed band in an NR unlicensed (NR-U) communication. The PRBs in the PRACH can be based on an occupied channel bandwidth (OCB) of the unlicensed band in the NR-U communication. A random access channel transmission in the PRACH can then be generated by interlacing the PRBs defining the PRACH.

The disclosure relates to a 5.sup.th Generation (5G) or 6.sup.th Generation (6G) communication system for supporting a higher data transmission rate. A method of operating an Integrated Access and Backhaul (IAB) donor node in a wireless communication system is provided. The method includes transmitting Frequency Division Multiplexing (FDM)-related information or Spatial Division Multiplexing (SDM)-related information to an IAB node, receiving necessary information from the IAB node, and transmitting or receiving backhaul data with respect to the IAB node by applying the FDM or the SMD, based on the FDM-related information or the SMD-related information.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a synchronization signal block (SSB) including a physical layer cell identifier (PCI), where one or more resource elements carrying the SSB overlap with resource elements carrying a downlink shared channel associated with another PCI. The PCIs may be for a serving cell or another cell, such as a non-serving cell. The UE may also receive one or more demodulation reference signals (DMRSs) in the one or more resource elements in the downlink shared channel. The UE may determine whether overlap is permitted between the resource elements by comparing the PCIs of the SSB and the downlink shared channel. In some examples, once the UE determines whether resource element overlap is permitted, the UE may process the DMRSs.

The present disclosure provides a method and device for determining an uplink-downlink switching point. The method is used in a base station. The method includes: setting configuration information for determining an uplink-downlink switching point; and sending the configuration information to the terminal, so that the terminal determines the uplink-downlink switching point according to the configuration information. Therefore, the present disclosure can prevent the terminal from performing invalid detection on an unlicensed carrier, and can also improve the speed and accuracy of determining the uplink-downlink switching point by the terminal.

A method and apparatus for performing autonomous transmission for performing collision mitigation and complexity reduction for non-orthogonal multiple access (NOMA) transmissions are disclosed. A wireless transmit/receive unit (WTRU) may receive a configuration with multiple SRs and associated preamble subsets, randomly select a preamble subset and select a SR configuration according to the randomly selected preamble subset based on the received configuration. The WTRU may transmit an SR associated with the selected preamble subset. Next the WTRU may select a preamble from the selected preamble subset, and transmit the selected preamble with a data transmission. Each SR associated with preamble subsets may be distinguished by time and frequency resources, sequence index value, or PUCCH index value.

Systems and methods are provided for determining which part or operation of one or more Secondary Cell (SCell) activation process (es) to defer or restart when an attempt to simultaneously perform multiple operations of the one or more SCell activation processes would cause interference. For example, radio frequency (RF) tuning and/or automatic gain control (AGC) settling for an SCell activation may be deferred until after a Hybrid Automatic Repeat Request (HARQ) for the SCell activation is sent by a UE to the SCell. In another example, RF tuning and/or AGC settling corresponding to the activation of a first SCell may be deferred until after RF tuning and/or AGC settling corresponding to the activation of a second SCell is complete.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE measures a first set of reference signals to determine a first channel state of a first channel between a first TRP and the UE. The UE measures interference received at the UE. The UE sends a first CSI report generated corresponding to the first channel state. The UE sends a second CSI report generated corresponding to the interference.

Certain aspects of the present disclosure provide techniques for power savings for reduced capability devices. A method that may be performed by a user equipment (UE) includes receiving a shared bandwidth part (BWP) configuration and a group common BWP configuration. The group common BWP configuration indicates a group common BWP shared by a group of UEs, including the UE, having one or more common capabilities or a common UE type. The method includes communicating using the group common BWP based on the group common BWP configuration.
