Embodiment 1
[0052] In this embodiment, the eNB uniformly configures the R-PUCCH resources and indicates that the resources allocated for the R-PUCCH use non-PUCCH resources. The specific process is: the eNB configures and instructs the RN about the resource configuration parameters of the R-PUCCH, and configures them for the R-PUCCH The resources use resources other than the direct transmission link PUCCH. In this embodiment, the base station allocates resources in units of RB pairs. On two slots (slots) of a subframe, each slot allocates one RB, and the RB pair hops or does not hop between slots.
[0053] In this embodiment, the eNB may configure the resource location for the R-PUCCH to be adjacent to the direct link PUCCH resource location in the frequency domain.
[0054] When the eNB configures and indicates the corresponding R-PUCCH resource configuration parameters of the RN, the resource configuration parameters can be configured by the eNB to indicate the RN through high-level sig...
example 1
[0058] This example provides a resource allocation method for the uplink control channel of the backhaul link. In this method, the eNB indicates the corresponding R-PUCCH resource index number n of the RN through high-layer signaling configuration. R-PUCCH and parameter N R-PUCCH init , where N R-PUCCH init Indicates the initial position of the physical resource RB pair of R-PUCCH. In this example, the resource index number n R-PUCCH = 7 and As an example to illustrate;
[0059] When the eNB configuration instructs the RN to report uplink control information in subframe n, the RN uses the resource index number n indicated by the eNB to R-PUCCH and parameter N R-PUCCH init Obtain the position of the physical resource RB pair of the R-PUCCH allocated;
[0060] In this example, the RN uses the resource index number n indicated by the eNB R-PUCCH = 7 and Obtain the location of the allocated R-PUCCH physical resource RB pair, the specific process is as follows:

example 2
[0071] This example provides a resource allocation method for the uplink control channel of the backhaul link. In this method, the eNB indicates the relative resource index number N of the corresponding R-PUCCH to the RN through high-level signaling configuration. R-PUCCH and parameter N R-PUCCH init ,Δ shift R-PUCCH ; among them, Δ shift R-PUCCH Extend the index interval in the frequency domain for uplink control information processing in the backhaul link; in this embodiment, the relative resource index number N R-PUCCH = 5, As an example to illustrate;
[0072] When the eNB configuration instructs the RN to report uplink control information in subframe n, the RN R-PUCCH and parameter N R-PUCCH init ,Δ shift R-PUCCH, and the first control information element (Control Channel Element, CCE) sequence number n where the backhaul link downlink control information is located CCE R , obtaining the position of the allocated R-PUCCH resource RB pair;
