Definitions

  • PUCCH is allocated to an RB pair in a subframe. RBs belonging to the RB pair occupy different subcarriers in each of the first slot and the second slot.
  • the latter is a reference signal sent together with a corresponding radio resource when the base station transmits a signal in downlink, and the terminal can perform channel measurement by receiving the reference signal, and thus can demodulate data.
  • This reference signal should be transmitted in the area where data is transmitted.
  • the base station transmits a contention resolution message to the terminal (S105). If there is no contention, the TC-RNTI becomes a C-RNTI, and then the UE detects and receives a PDCCH addressed with the C-RNTI.
  • FIG. 10 shows an example of setting CRS transmission bands and setting of PDCCH and E-PDCCH in NCT.
  • the M2 reception timing of the UE can be adjusted as follows.
  • a cell specific offset value (let N (e1) PUCCH, q ) for determining an implicit PUCCH resource may be provided by the base station. Then, the implicit PUCCH resource may be determined based on the lowest ECCE index (n ECCE, q ) of the UL grant transmitted in the E-PDCCH and the N (e1) PUCCH, q .
  • the N (e1) PUCCH, q may be a field value to which the N (1) PUCCH is transmitted or the same value may be used.
  • Processors 110 and 210 may include application-specific integrated circuits (ASICs), other chipsets, logic circuits, and / or data processing devices.
  • the memory 120, 220 may include read-only memory (ROM), random access memory (RAM), flash memory, memory card, storage medium, and / or other storage device.
  • the RF unit 130 and 230 may include a baseband circuit for processing a radio signal.
  • the above-described technique may be implemented as a module (process, function, etc.) for performing the above-described function.
  • the module may be stored in the memories 120 and 220 and executed by the processors 110 and 210.
  • the memories 120 and 220 may be inside or outside the processors 110 and 210, and may be connected to the processors 110 and 210 by various well-known means.

Abstract

La présente invention concerne un procédé et un appareil pour la recherche d'informations de commande d'un terminal dans un système de communication sans fil. Le procédé consiste à : rechercher dans un premier espace de recherche commun (CSS) des informations système de premier type transmises par une station de base ; recevoir un message de commande de ressource radio (RRC) par l'établissement d'une connexion RRC avec la station de base sur la base des informations système de premier type ; et rechercher dans un second espace de recherche commun des informations système de second type à condition que le second espace de recherche commun ait été configuré par le message RRC.
