A communication method, a terminal, and a network side device are provided. The method includes: receiving first configuration information transmitted by a network side device, where the first configuration information is used for configuring a working area for signal transmission, and the working area is used for performing functions of a cell; and performing signal transmission in the working area according to the first configuration information.

This application discloses an SN synchronization method and apparatus for multicast broadcast service, a device, and a readable storage medium. The method includes: obtaining a first radio interface SN of a first multicast broadcast service received in a first cell and a second radio interface SN of the first multicast broadcast service received in a second cell; and sorting data packets of the first multicast broadcast service according to the first radio interface SN and the second radio interface SN; where the first radio interface SN and the second radio interface SN are in a same SN set, and the first radio interface SN and the second radio interface SN are at least partially different.

A first base station receives a second base station addition request. The second base station addition request indicates for each packet flow of packet flows of a wireless device: whether each packet flow is for at least one vehicle-to-everything (V2X) service; and a quality-of-service indicator of each packet flow. An indication of an acceptance or rejection of each packet flow, of the packet flows, is sent based on whether each packet flow is for the at least one V2X service.

Disclosed in embodiments of this application are a data processing method and apparatus, a terminal device, and a non-transitory computer-readable storage medium. When the terminal device determines that a delay is less than a standard index, estimation of a load situation of a base station is triggered. Based on an obtained load value, a QoS service request can be initiated by the terminal device in a accordance with a determination that the base station is heavily-loaded, thereby effectively avoiding ineffective calling of a QoS service by the terminal device and improving effectiveness of service calling.

A method and wireless device for determining a time interval, T2, for selecting a time-frequency resource are disclosed. According to one aspect, a method includes determining the time interval based on at least one parameter serving as a proxy indicative of a likelihood of collision. In some embodiments, at least one of the at least one parameter is a priority level indication, such that a higher priority transmission results in a lower value of T2.

An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to perform determining, per a communication service to which resources are to be allocated, a metric value using a first predefined set of rules, determining, per a sensing service to which resources are to be allocated, a metric value using a second predefined set of rules, sorting communication services to which resources are to be allocated and sensing services to which resources are to be allocated based on the metric values to a sorted order using a third rule, and allocating resources for the communication services and the sensing services based on the sorted order.

A first base station receives an aggregate maximum bit rate of a wireless device; and an indication of packet data convergence protocol (PDCP) duplication for a bearer. Duplicated PDCP packets of the bearer are received from a PDCP layer of a second base station. The duplicated PDCP packets are transmitted to the wireless device via the bearer. An aggregate bit rate between the wireless device and the first base station is limited based on the aggregate maximum bit rate. The aggregate bit rate is determined while ignoring the duplicated PDCP packets.
