  • the Un DL/UL subframe configuration ratio is 2:1, and the RN needs to be on an Un UL subframe.
  • the generated ACK/NACK feedback information is processed by the PUCCH format lb of the channel selection method, and the two antennas are respectively mapped to the UnPUCCH resource corresponding to the allocated corresponding UnPUCCH index according to the channel selection rule, and are uplinked to the eNB.
  • the high layer signaling in this embodiment mainly refers to RRC signaling.
  • the present invention further provides a configuration control entity, which is configured to implement a backhaul link physical uplink control channel (UnPUCCH) resource allocation.
  • the configuration control entity includes a configuration module, where:
  • the configuration module is configured to: configure, according to a radio resource control message, a corresponding n UnPUCCH resource indexes by using a radio resource control message according to an Un PUCCH transmission mode configured for the relay station and a PUCCH format used by the relay station, where n is greater than or equal to An integer of 1.
  • the foregoing configuration control entity further includes: any one or more of a base station, a higher-level relay station, a cell cooperation entity, a gateway, a mobility management, an evolved universal terrestrial radio access network, an operation management, and a maintenance manager. The combination.
  • the radio resource control message is a radio resource control connection relay station reconfiguration message.
  • the foregoing technical solution provides a method and system for UnPUCCH resource allocation, to configure Un PUCCH resources by using RRC signaling.
  • the network side passes RRC signaling
  • the RN configures one or more backhaul link uplink control channel Un PUCCH resource indexes, and indicates the Un PUCCH resources allocated by the RN.

Abstract

La présente invention concerne un procédé et un système pour l'allocation de ressources de canal de commande de liaison montante physique (PUCCH) de liaison terrestre. Le procédé comprend l'étape suivante: un côté réseau configure un nombre n d'index de ressources de canal PUCCH de liaison montante pour un nœud relais via une information de commande de ressources radio selon le mode de transmission du canal PUCCH de liaison montante utilisé pour configurer le nœud relais et le mode de canal PUCCH utilisé par le nœud relais, n étant un nombre entier égal ou supérieur à 1. Grâce au procédé et système, des ressources de canal PUCCH de liaison montante peuvent être allouées par des signaux de commande de ressources radio (RCC).
