Radio communication device and radio communication method

Provided is a radio communication device capable of reducing interference, caused by non-SR transmission, with a basic service set (BSS) performing spatial reuse (SR) transmission. An SR transmission resource control unit (107) of the radio communication device (SR initiator) (100) determines transmission resources for an SR signal to be transmitted by means of SR to a second BSS other than a first BSS to which the radio communication device (100) belongs on the basis of radio quality information transmitted from other radio communication devices (SR responders) in the first BSS. A radio transmission/reception unit (101) transmits the SR signal by using the determined transmission resources.

11611417 · 2023-03-21 · ·

A data unit comprising bits to transmit over one or more frequency segments in a frequency range is obtained. An effective bandwidth in each frequency segment of the frequency range is determined, where the effective bandwidth excludes bandwidth of one or more punctured subchannels in a respective frequency segment. Bits are encoded based on the effective bandwidth of each frequency segment followed by parsing the encoded bits to one or more streams and parsing the encoded bits of a stream to the one or more frequency segments. The parsing of the encoded bits of the stream comprises allocating a first number of consecutive encoded bits to a first frequency segment and allocating a second number of consecutive encoded bits to a second frequency segment, wherein the first number and the second number are based on the effective bandwidth of the first frequency segment and the second frequency segment. The encoded bits are modulated and mapped to subcarriers for transmission.

The base station may update a configuration for CSI or for CSI-RS based on the request. For example, the base station may update a periodicity for the periodic CSI-RS configuration based on the requested periodicity.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a resource for measuring cross link interference (CLI). The UE may determine that the resource overlaps with (e.g., at least partially overlaps) one or more symbols or a transmission occasion. The UE may determine, according to what the resource overlaps with, whether to measure CLI over the resource. For example, if one or more of the symbols is uplink or if the resource verlaps a transmission occasion, the UE may not measure CLI. If one or more of the symbols are downlink, the UE may measure CLI. If one or more of the symbols is flexible or has an unknown type, the UE may determine whether to measure CLI based on a type of the control signaling.
