Embodiment 1
[0123] In this example, the implementation description of the link establishment process will be carried out.
[0124] Figure 5 Implement a flow diagram for the path configuration process, as shown in the figure, which may include:
[0125] Step 501, DgNB sends path configuration command to RN8 via RN7;
[0126] Step 502, RN8 returns a path configuration response to DgNB via RN7.
[0127] The specific process can be as follows:
[0128] 1: RN8 accesses the network as a UE after it is turned on, and selects RN7 to access the network according to the cell selection criteria (standard) during the network access process.
[0129] 2: Since RN7 does not have an RRC (Radio Resource Control, radio resource control) function, the RRC of the DgNB configures measurement for RN8, and RN8 performs measurement reporting to RN7 and RN2. , that is: during implementation, on the DgNB side, the DgNB may configure the measurement of the second RN and the third RN for the first RN through th...
Embodiment 2
[0134] In this example, the implementation of the link restoration process will be described.
[0135] As described in Embodiment 1, currently RN8->RN2->DgNB is an active link, and RN8->RN7->DgNB is a standby link.
[0136] Method 1:
[0137] It is assumed that the RN8->RN2 link is interrupted, and RN8 initiates the activation of the backup link, and activates the link deletion process.
[0138] That is, during implementation, when the active relay link path is interrupted, it may further include:
[0139] activate an alternate trunk link path; and / or,
[0141] Image 6 It is a schematic diagram of the implementation process of mode 1 in the case of link interruption, as shown in the figure, which may include:
[0142] Step 601, RN8 sends a request for activating a backup path to DgNB via RN7;
[0143] In step 602, the DgNB returns an acknowledgment of activating the standby path to RN8 via RN7.
[0144] In an implementation, ...
Embodiment 3
[0174] In this embodiment, the UE has multiple active links at the same time, and the UE can freely select any link for transmission. That is, it is implemented when there are multiple active relay link paths and multiple backup relay link paths. In this case:
[0175] On the DgNB side, when there are at least two activated relay link paths, further include:
[0176] discarding excess data when the same data is transmitted on each active relay link path; and / or,
[0177] When the data transmitted on different activated relay link paths are different, the different data are combined and then restored.
[0178] On the access RN side, when there are at least two activated relay link paths, further include:
[0179] transmit the same data on each active trunk link path; and / or,
[0180] After the data is divided into different parts, it is transmitted on different active relay link paths.
[0181] Specifically, the RN can perform two types of sending on multiple links:
[0182...

Abstract
The invention discloses a multi-hop relay configuration method, equipment and device, including: when a first RN accesses a network through a second RN, the DgNB configures the second RN and measures the third RN for the first RN; After receiving the measurement report of the first RN, the activated relay of the first RN is determined according to the channel quality between the first RN and the second RN and the third RN, as well as the load of the second RN and the load of the third RN link path, and use other relay link paths as backup relay link paths; notify the first RN of the relay link path configuration result. When the first RN accesses the network through the second RN, the measurement is performed according to the configuration of the DgNB; the first RN receives the configuration result of the relay link path sent by the DgNB, activates the relay link path according to the configuration, and activates the relay link path according to the configuration. The link path serves as an alternate trunk link path. By adopting the present invention, a feasible technical solution for the multi-hop relay configuration process is proposed.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a multi-hop relay configuration method, equipment and device. Background technique [0002] In the 5G system, in order to expand network coverage, relay base stations are introduced into 5G. To further extend network coverage, multi-hop relays are also allowed. Then in the multi-hop relay system, in order to select a low-latency, high-QoS (Quality of Service, quality of service) path to access the Donor gNB (donor base station; gNB: next generation NodeB, next-generation base station), the Donor gNB needs The path is configured, and the RN (Relaynode, relay node) needs to be reconfigured when the path is interrupted. [0003] However, the disadvantage of the prior art is that there is no technical solution for the multi-hop relay configuration process. Contents of the invention [0004] The present invention provides a multi-hop relay configuration met...
