Apparatus and method for managing resource of radio unit of base station in wireless communication system
The disclosure relates to a pre 5th generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th generation (4G) communication system such as long term evolution (LTE). A method for operating a radio unit (RU) of a base station is provided. The method includes transmitting, to a digital unit (DU), a first message comprising a value indicating the maximum number of masks for one resource area, and receiving, from the DU, a second message generated based on the value, wherein the mask may indicate resources to which the same beam is applied within the resource area.

Provided are a method, device and storage medium for configuring a starting symbol position of an uplink data channel. The method includes: determining a configuration value of a first type parameter set, where the first type parameter set is a set of uplink data parameters; determining a configuration range of a starting symbol position of an uplink data channel according to the configuration value of the first type parameter set; and selecting a starting symbol position of the uplink data channel from the configuration range of the starting symbol position of the uplink data channel, and notifying a receiving end of the selected starting symbol position of the uplink data channel.
Coordination for partial reciprocity estimation
Methods, systems, and devices for wireless communications are described. A first device may receive a first reference signal from a second device and may generate a channel status feedback message based on the first reference signal. The first device may bundle the second reference signal and the channel status feedback message and may transmit the second reference signal and the channel status feedback to the second device. The first device may initiate a data transfer with the second device based on transmitting the second reference signal and the channel status feedback message.
Contention window adjustment for group channel occupancy time sharing
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an adjusted contention window size for a listen-before-talk (LBT) procedure that increases channel access time fairness between a plurality of different groups of UEs. The UE may determine, via the LBT procedure, that a channel is idle based at least in part on the adjusted contention window size. The UE may transmit, to other UEs in a group of UEs that includes the UE, control information that enables a group channel occupancy time (COT) associated with the channel to be shared with the other UEs in the group of UEs. Numerous other aspects are described.
Techniques to enhance user equipment (UE) beam scan
A wireless communication device can expedite beam scans for beam management. The wireless communication device can perform a beam scan using a first beam reference signal of a synchronization signal block (SSB) and a second beam reference signal associated with a physical broadcast control channel (PBCH) of the SSB. For each synchronization signal block (SSB) index (e.g., transmit beam) monitored by the wireless communication device, the wireless communication device can obtain a respective beam quality metric on each of two or more respective receive beams using at least the first and second beam reference signals. Other aspects, features, and embodiments are also claimed and described.
Radio link monitoring across multiple frequencies in wireless communications
Methods, systems, and devices for wireless communications are described in which a narrowband device may communicate in a wireless communications network according to frequency hopping techniques. Devices using narrowband communications and frequency hopping techniques may maintain separate radio link monitoring (RLM) processes, beam failure detection (BFD) processes, beam failure recovery (BFR) processes, or combinations thereof, for multiple bandwidth parts (BWPs) or hop regions of a full channel bandwidth. Such separate processes may provide for enhanced estimates of beam failures per BWP or hop region, which may be used to enhance communications reliability.

A method, wireless device and network node for CSI feed-back with multiple interference hypotheses are disclosed. According to one aspect, a method implemented in a wireless device (WD) includes receiving a configuration for Channel State Information (CSI) measurement including a first Non-Zero Power Channel State Information-Reference Signal (NZP CSI-RS) resource set for channel measurement and a second NZP CSI-RS resource set for interference measurement, the first NZP CSI-RS resource set having only one NZP CSI-RS resource. The method also includes measuring CSI based on the first and the second NZP CSI-RS resource sets.
