Embodiment Construction

[0046] It should be understood that the term "and / or" used herein is only an association relationship describing associated objects, which means that there may be three relationships, for example, A and / or B, which may mean that A exists alone, and A and B exist simultaneously. B, there are three situations of B alone.

[0047] In the prior art, the connection between the remote UE and the relay UE is established through the following process:

[0048] 1) A process in which the remote UE discovers the relay UE. The discovery process includes two models:

[0049] The first model: the relay UE sends a UE-to-Network Relay Discovery Announcement (UE-to-Network Relay Discovery Announcement) message; the remote UE receives the UE-to-Network Relay Discovery Announcement message, thereby discovering the relay UE.

[0050] The second model: the remote UE sends a UE-to-Network Relay Discovery Solicitation (UE-to-Network Relay Discovery Solicitation) message; the relay UE receives the ...

Abstract

The present application provides a signal processing method and device. In this application, the first user equipment determines the first resource used by the second user equipment to send the second message according to the first message, and detects and / or receives the second message on the first resource, so as to prevent the first user equipment from The power consumption caused by detecting and / or receiving the second message on more resources is too high, and the power consumption of the first user equipment is reduced.

Description

technical field [0001] The present application relates to wireless communication technologies, and in particular to a signal processing method and device. Background technique [0002] Device-to-Device (D2D) communication based on cellular network, or Proximity Service (ProSe), is a kind of communication under the control of the system that allows devices to directly communicate with each other by reusing cell resources. New technology of communication. D2D communication can increase the spectrum efficiency of the cellular communication system, and solve the problem of lack of spectrum resources in the wireless communication system to a certain extent. [0003] D2D communication includes a relay operation from a user equipment (User Equipment, UE) to a network, that is, a remote UE can connect to the network through the relay UE. The remote UE can discover the relay UE through a side link discovery message. The remote UE can also establish a connection with the relay UE. ...
