Embodiment 1

[0028]In this embodiment, the RNUE is instructed by the DeNB through configuration signaling or determined by the UE itself. The RNUE broadcasts RRQ physical resource configuration information through the RBC, where the resource pool for sending RRQ is the same as the resource pool for sending RBC. Detect the RRQ from the UU, and further feed back the RRP for the received RRQ on the corresponding RRP physical resource. The UU obtains RRQ resource configuration information by receiving RBC signaling. When the UU generates a relay demand or detects the paging information for the UU in the RBC, it sends RRQ on the physical resource, and further in the corresponding RRP physical Check RRP on the resource. Such as image 3 As shown, the specific implementation steps are as follows:

[0029] Step 310: the RNUE sends the RBC message on the corresponding physical resource.

[0030] In this embodiment, the RBC message is sent through the D2D broadcast communication method defined in...

Embodiment 2

[0053] In this embodiment, the RNUE is instructed by the DeNB through configuration signaling or determined by the UE itself, and the RNUE sends the RBC message in the corresponding resource pool. In this embodiment, the resource pool for sending the RBC is different from the resource pool for sending the RRQ, but the two There is a binding relationship between them, the binding relationship is configured by the DeNB, or defined by the standard, or written into the UE (including RNUE and UU) in a pre-configured way, and the RNUE further detects in the RRQ resource pool the information from the UU RRQ, and further feed back the RRP for the accepted RRQ on the corresponding RRP physical resource. The UU receives RBC signaling and determines the RRQ transmission resources. When the UU generates a relay demand or detects paging information for the UU in the RBC, it sends RRQ on the physical resources, and further transmits RRQ on the corresponding RRP physical resources. Check the...

Embodiment 3

[0077] In this embodiment, the RNUE is instructed by the DeNB through configuration signaling or determined by the UE itself, and the RNUE sends an RBC message in the corresponding resource pool. In this embodiment, the RBC message only includes the paging message sending window configuration, and the RNUE is in The paging message for one or more UUs is sent within the SA period of the paging message sending window. In this embodiment, the RRQ resource pool may be determined by using the method in Embodiment 1 or Embodiment 2. The RNUE detects the RRQ from the UU in the RRQ resource pool, and further feeds back the RRP for the received RRQ on the corresponding RRP physical resource. The UU receives the RBC signaling, determines the configuration of the sending window of the paging message, and determines the sending resource of the RRQ according to the method in Embodiment 1 or Embodiment 2. The UU shall detect a paging message during the paging message sending window. When ...

Abstract

This application proposes a method of establishing a relay connection based on a relay network based on device -to -device D2D broadcast communications, including: RNUE sends RBC messages according to Denb instructions, provides UU with the required information for the selection of relay nodes, and further corresponds to the corresponding correspondenceDetecting the RRQ message from UU on the resource. For accepting relay requests, RNUE confirms the relay connection between the RRP message and the corresponding UU.UU determines the sending resources of the RRQ message according to the receiving RBC message, the standard definition or pre -configuration, so as to establish a connection with the RNUE.Through the method made by this application, the establishment of RNUE and UU can be changed with smaller standards.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular, the present application relates to a method and device for selecting a relay node in a relay network based on D2D broadcast communication. Background technique [0002] At present, the device-to-device (D2D) communication technology has been accepted by the 3GPP standard due to its great potential value in the field of public safety and ordinary civilian communication, and some functions have been standardized in 3GPP Rel-12 , including the mutual discovery of D2D terminals in the cell coverage scenario and the D2D terminals in the cell coverage (In Coverage, IC) scenario, the cell partial coverage (Partial Coverage, PC) scenario and the no cell coverage (Out of Coverage, OC) scenario broadcast communication between. [0003] Currently, the 3GPP Rel-12 standard defines two modes of D2D broadcast communication, referred to as Mode 1 (Mode 1) and Mode 2 (M...
