Certain aspects of the present disclosure provide techniques for channel access using an intelligent reflecting surface (IRS). A method that may be performed by a network entity includes monitoring candidate paths for channel access, wherein the candidate paths include one or more paths through an intelligent reflecting surface; determining at least one path among the candidate paths for communications with a first wireless node based at least in part on one or more criteria associated with the candidate paths and obtained from monitoring the candidate paths; and communicating with the first wireless node via the at least one path.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a buffer status report (BSR) in response to a data radio bearer (DRB) for a secondary cell group (SCG) being a split DRB, the SCG being deactivated, and a buffer size satisfying a threshold for transmitting the BSR to activate the SCG. The UE may transmit the BSR. The UE may communicate on the SCG after activation of the SCG. Numerous other aspects are described.

A device comprises a processor. The processor may be configured to: receive information about an existing cell site; and generate a distance histogram for the existing cell site based on the received information. Additionally, the processor may be configured to at least one of: calculate, using the generated distance histogram, a first value that indicates an amount of traffic to be offloaded from the existing cell site to a new cell site, or calculate, using the generated distance histogram, a second value that indicates an amount of traffic to be offloaded from operating bands of the existing cell site as a result of an upgrade at the existing cell site.

Disclosed is a fifth generation (5G) or sixth generation (6G) communication system for supporting higher data transmission rate. A method for providing an ultra-reliable and low-latency communication (URLLC) service in an ultra-reliable and low-latency communication function (URLLCF) of a mobile communication system is provided. The method includes receiving an end-to-end latency request message from an application function (AF) device, the latency request message including a latency requirement and at least one of generic public subscription identifier (GPSI) information of a specific user equipment (UE), data network name (DNN), or single-network slice selection assistance (S-NSSAI), performing a subscription procedure of URLLC service condition with a unified data management (UDM)/user data repository (UDR) device, obtaining location information of the UE, identifying whether the location information conforms to a range required by the URLLC service, configuring a policy and association satisfying a latency for the URLLC service to the UE, and providing a URLLC service notification to the AF based on the configuration.

Systems, devices, methods, and computer-readable storage media of channel switching. One device for channel switching includes a memory and at least one processor. The at least one processor is configured to communicatively couple with one or more client devices, using one of a primary bandwidth channel or a secondary bandwidth channel and transmit a first trigger on at least the primary bandwidth channel to at least a first client device of the one or more client devices based on at least one of (i) a bandwidth availability (ii) a quality of service parameter, or (iii) a secondary bandwidth switching capability, wherein the first client device switches from the primary bandwidth channel to the secondary bandwidth channel in response to the first trigger.

A base station device includes: a storage that stores a group indicating unit data subject to retransmission out of predetermined number of unit data included in transmission data to be transmitted to a terminal device, and identification information to identify the group, in an associated manner; a receiver that receives, from the terminal device, identification information corresponding to transmission data transmitted to the terminal device; a communication controller that refers to the storage based on the received identification information, and that determines retransmission of unit data included in a group corresponding to the received identification information out of the transmission data; and a transmitter that transmits unit data included in the group determined to be retransmitted by the communication controller, to the terminal device.

An information processing method, an apparatus, and a communication device are provided. The information processing method includes: triggering a pre-emptive BSR; and canceling the pre-emptive BSR according to a first status in a process from triggering of the pre-emptive BSR to generation of the pre-emptive BSR, where the first status includes at least one of the following: a reception status of uplink data; and a triggering status of a target BSR, where the target BSR is at least one of a regular BSR and a periodic BSR.

This disclosure provides a time synchronization packet processing method and apparatus. The method includes: A terminal device receives first indication information, where the first indication information indicates the terminal device to enter an activation state of time synchronization for a first clock source, or the first indication information indicates the terminal device to enter a deactivation state of time synchronization; and processes a time synchronization packet of the first clock source based on the first indication information.

A device may include one or more processors configured to determine a first traffic identifier of a first wireless traffic stream, from a plurality of traffic identifiers.
