Description

Relay method, user equipment and base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a relay method, a user equipment, and a base station.

Background

Currently, mobile communication seeks not only to maximize capacity, but also to have a wider coverage, i.e., a coverage of mobile communication regardless of where a User Equipment (UE) moves. For this reason, the us bell laboratory proposes a cellular networking concept. It divides a mobile communication service area into a number of coverage areas, called cells, with a regular hexagonal basic geometry. A lower power transmitter serves a cell and a significant number of UEs are located within a smaller area.

In fact, the mobile communication network cannot fully guarantee the comprehensive seamless coverage of the network at the time of deployment. At present, for a user equipment which is outside a network coverage area and cannot receive a network signal or a user equipment with a poor network signal in the network coverage area, the user equipment with the good network signal in the network coverage area can be searched as a relay user equipment to establish connection with a network, as shown in fig. 1. When UE B is out of network coverage, it may establish a connection with the network through UE a within network coverage. The UE a is called Relay user equipment (Relay UE) or a Relay terminal, that is, a user equipment or a terminal providing a Relay service; UE B is called a user equipment to be relayed (Remote UE) or a terminal to be relayed.

In the prior art, a user equipment to be relayed selects an available relay user equipment according to relay history information broadcasted by the user equipment with relay capability started and information on whether the user equipment to be relayed is currently connected, and sends a relay request to the available relay user equipment so as to establish connection with a network through the relay user equipment. However, in the prior art, the communication quality (including the signal strength and/or the signal quality between the relay user equipment and the base station) between the available relay user equipment and the base station selected according to the above method is not guaranteed, that is, the communication quality between the relay user equipment and the base station may be poor, so that the relay user equipment is difficult to establish a stable and effective connection with the network through the relay user equipment.
