Problems solved by technology

However, when there are too many UEs simultaneously sending data packets in the resource pool in the same area, the sending of data packets in the resource pool cannot be performed normally, that is, congestion of the resource pool is caused.
At present, the terminal equipment carried by pedestrians cannot understand the congestion of the resource pool due to reasons such as reducing power consumption

Abstract

Embodiments of the present disclosure relate to methods and devices for congestion control. Specifically, the embodiments of the present disclosure relate to methods implemented at network devices and terminal devices, and corresponding network devices and terminal devices. For example, a method implemented at a network device includes receiving a first congestion level report from a first terminal device located in an area of ​​a cell of the network device, the first congestion level report indicating that the first a first estimated congestion level of a resource pool assigned by the network device to the area as determined by the terminal device; determining a congestion level of the resource pool based at least in part on the first estimated congestion level; and broadcasting an indication of the The congestion level information of the congestion level is provided for the second terminal device located in the area to receive, wherein the second terminal device cannot directly estimate the congestion level of the resource pool.

Description

technical field [0001] Embodiments of the present disclosure generally relate to communication technologies, and more particularly, to methods and devices for congestion control. Background technique [0002] Currently, for the 3rd Generation Partnership Project (3GPP), research on long-term evolution (LTE)-based "vehicle-to-external" (V2X) services is being continuously conducted in order to explore a widely-deployed LTE network for The "connected car" (ie, connected cars) opportunity for the transportation industry. LTE-based V2X consists of three parts: vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P) (and corresponding pedestrian-to-vehicle (P2V)), and vehicle-to-infrastructure / network (V2I / N) . V2P communication is expected to improve road safety for pedestrians. [0003] In order to realize V2P (or P2V) communication, vehicles (for example, automobiles) terminal devices and pedestrian terminal devices in such as a cell or a part of a cell (also referred to as a...
