Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Disclosed is a bandwidth part (BWP) switching method, a terminal, and a storage medium. The method includes: receiving target downlink control information (DCI) from a network device; wherein the target DCI comprises a first BWP, and the target DCI is configured to trigger the terminal to perform a BWP switching; de-enabling a timer-based BWP switching function according to the target DCI; wherein the timer-based BWP switching function indicates triggering the terminal to perform the BWP switching in response to no data transmission existing between the terminal and the network device within a timer duration of a timer; and switching a current BWP to the first BWP.

A wireless device receives configuration parameters associated with a cell. The wireless device receives an activation command indicating activation of a transmission configuration indicator (TCI) state having a downlink reference signal, the command indicating activation of the TCI state for a control resource set (coreset). The wireless device receives downlink control information (DCI) indicating uplink resources of a time slot of an active uplink bandwidth part of the cell, where a sounding reference signal resource indicator field is absent in the DCI. The wireless device transmits, via the uplink resources, an uplink signal with a transmission power determined based on the reference signal, the transmitting being in response to a parameter enabling a default pathloss reference signal determination and the uplink resources occurring after a predetermined number of measurement samples of the downlink reference signal is obtained.

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.

A first node transmits a first signal; receives a second signal; and transmits a third signal on a target time-frequency resource block; the second signal is used to indicate a first time-frequency resource block, the first time-frequency resource block is used to determine a target time-frequency resource set, and the first time-frequency resource block is one of the multiple time-frequency resource blocks comprised in the target time-frequency resource set; the target time-frequency resource block is one of the multiple time-frequency resource blocks comprised in the target time-frequency resource set, and whether the third signal carries a first-type information block is used to determine the target time-frequency resource block out of the target time-frequency resource set; the first-type information block comprises control-plane information. The present application transmits a Message 3 through additional time-frequency resources to reduce the conflict of random access to mainstream services.

Embodiments of this application provide a communication method, a communication apparatus, and a readable storage medium. One example method includes: A network device sends a configuration information set to a terminal device, receives assistance information from the terminal device, and determines target frequency domain information from frequency domain information based on the assistance information.

Provided a method for configuring an unlink signal. The method includes: indicating, by a first communication node through signaling, a resource or a frequency hopping manner used by a second communication node for transmitting the uplink signal, or predefining, by the first communication node and the second communication node, the resource or the frequency hopping manner used by the second communication node for transmitting the uplink signal. Further provided are an apparatus for configuring an uplink signal, a method and apparatus for determining an uplink signal, a base station, a terminal and a storage medium.

A first receiver receives first information; and a first transmitter transmits a first signal in a first time-frequency resource block, the first signal carrying a second bit block; herein, a first bit block is used for generating the second bit block; the first bit block comprises a first bit sub-block and a second bit sub-block, the priority corresponding to the first bit sub-block being higher than that corresponding to the second bit sub-block; the number of REs in the first time-frequency resource block used for transmitting the second bit block is no greater than a first value, and the number of bits comprised in the first bit sub-block is used to determine the first value; the number of bits comprised in the first bit sub-block and the first information are used together to determine a second value.

This application provides a reference signal transmission method. The method includes: A transmit end determines a time-frequency resource occupied by a reference signal, where the time-frequency resource includes M symbols in time domain and N subcarriers corresponding to each of the M symbols in frequency domain, M is an integer greater than or equal to 2, and N is an integer greater than 1; the transmit end generates a reference signal sequence with a length of M×N, and maps the reference signal sequence to the time-frequency resource for sending; and accordingly, a receive end receives the reference signal on the time-frequency resource.

A resource determining method and device are provided. The method may be performed by a terminal device, including: determining a remaining frequency domain resource in a resource pool according to a sub-channel size; and using the remaining frequency domain resource as a first sub-channel independently, or containing the remaining frequency domain resource in the resource pool within a second sub-channel.
