The present disclosure provides a random access method and a terminal. The method of the present disclosure includes: when non-contention random access is initiated and current uplink and downlink Band Width Parts BWPs are inconsistent with uplink and downlink BWPs configured by a base station for non-contention random access, setting, by the terminal, active BWPs as an uplink BWP and a downlink BWP having the same number, and performing contention random access on the active BWPs; or setting, by the terminal, the active BWPs as the uplink BWP and the downlink BWP configured by the base station for non-contention random access, and performing the non-contention random access on the active BWPs.

A communication system for performing non-DRX-aware channel resource allocation is described. The communication system includes a plurality of radio points (RPs), each configured to exchange radio frequency (RF) signals with a plurality of user equipment (UEs) at a site. The communication system also includes a baseband controller communicatively coupled to the plurality of radio points. The baseband controller is configured to determine, for each RP communicating with a UE, available channel resources in each of a plurality of subframes. The baseband controller is also configured to determine a least-loaded subframe that has the most available channel resources. The baseband controller is also configured to assign an available channel resource in the least-loaded subframe to the UE.

Embodiments described herein relate to methods and apparatuses for configuring communication between abase station and at least one wireless device, the base station using an antenna array, wherein antenna ports in the antenna array are coupled to radio frequency branches. The method comprises determining a first radio frequency bandwidth for a first radio frequency branch based on one or more factors associated with traffic served by a plurality of radio frequency bandwidth parts, and configuring the first radio frequency branch to serve frequencies within the first radio frequency bandwidth.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a subset of time resources in a wake up signal (WUS) pool, wherein the WUS pool includes contiguous candidate time resources for receiving a WUS. The UE may detect the WUS based at least in part on monitoring the subset of time resources. Numerous other aspects are provided.

An operating method of a first terminal in a wireless communication system may include: receiving at least one configuration information about at least one reference signal transmitted by a second terminal; selecting at least one piece of the at least one configuration information when an uplink bandwidth part of the second terminal and a downlink bandwidth part of the first terminal are different from each other; measuring cross-link interference (CU) through the reference signal based on the selected configuration information; and reporting a result of the measuring, to the base station.

This application provides example positioning methods and example apparatuses. One example method includes sending, by a positioning management network element, a positioning measurement request to a positioning measurement network element. The positioning measurement request is used to request the positioning measurement network element to feed back channel state information of a terminal device. Then, the positioning management network element receives a positioning measurement response from the positioning measurement network element. The positioning measurement response includes the channel state information of the terminal device. Then, the positioning management network element determines a location of the terminal device based on the channel state information of the terminal device.

This disclosure provides methods, devices and systems for wireless communications over a 320 MHz bandwidth. Some implementations more specifically relate to signaling techniques for indicating the bandwidth of a physical layer convergence protocol (PLCP) protocol data unit (PPDU) transmitted in a secondary 160 MHz channel of the 320 MHz bandwidth. In some implementations, an access point (AP) may transmit an aggregated PPDU (A-PPDU) that includes a first sub-PPDU transmitted within a primary 160 MHz channel and a second sub-PPDU transmitted within a secondary 160 MHz channel. In such implementations, the first sub-PPDU may carry bandwidth information indicating the bandwidth of the first sub-PPDU within the primary 160 MHz channel and the second sub-PPDU may carry bandwidth information indicating the 320 MHz bandwidth.

A mechanism is presented for attributing users to one or more of a plurality of sub-bands in a multiple access communications system, wherein in an initial assignment phase, a first user is selected for a sub band, for example on the basis of a user priority. Users having complementary channel gains to that of the first user are identified, and then a second sub-band user maximizing a performance metric reflecting the achieved throughput, and/or fairness across users, is selected to accompany the first user on that sub-band. The initial assignment phase may terminate once all users have been assigned to a sub-band once. After the first phase is complete, the first user for each sub-band may be the user whose achieved total throughput is furthest from a target throughput defined for that user, wherein each user is assigned to the remaining sub-band to which no first user is currently attributed offering the highest channel gain for that user. Mechanisms for determining user priority, making provisional and definitive power allocations, and performance metrics are proposed.

A data transmission method, an apparatus, and a communications device include sending, by a first device, first information using a first carrier, where the first information indicates that the first device uses N carriers in M carriers to send data, where N is an integer greater than or equal to 2, and N is less than or equal to M, sending, by the first device, the data using the N carriers.

Example communication methods and a communications apparatus are described. One example method includes receiving first information by a terminal device, where the first information indicates an identifier of a first frequency domain resource, and the first frequency domain resource is contiguous in frequency domain. When a status of the terminal device is a first state, the terminal device with a network device on a second frequency domain resource based on the first information, where the second frequency domain resource includes a plurality of segments of contiguous frequency domain resources, and the first frequency domain resource is one segment of the plurality of segments of contiguous frequency domain resources. According to the foregoing method, the terminal device may communicate, based on the received first information, with the network device on the second frequency domain resource when the status of the terminal device is the first state.
