  • the C-RNTI (16-bit long) is an identifier of the UE allocated by the base station to the connected state.
  • the base station uniquely identifies the UE in a cell by using the C-RNTI, and simultaneously schedules the terminal in the cell by using the C-RNTI.
  • the corresponding base station allocates a C-RNTI to it, and when the UE switches to another cell due to mobility or other reasons, the base station of the new cell reassigns the C-RNTI to it, that is, The C-RNTI is only valid in the current cell.

  • CA Carrier Aggregation
  • UE User Equipment
  • Carrier aggregation enables the UE to simultaneously use multiple component carriers (CC, Component Carrier) for uplink and downlink communication, thereby supporting high-speed data transmission.
  • CC Component Carrier
  • some component carriers can be released, and only one resident carrier is reserved, and the released transmission resources can be used by other UEs, thereby achieving flexible and dynamic purposes.
  • the carrier aggregation of the Long Term Evolution (LTE) system can be divided into intra-base station cell aggregation and inter-base station cell aggregation.
  • the cell aggregation in the base station means that multiple CCs used by the UE are controlled by the same base station. In the current protocol, only cell aggregation within the base station is supported.
  • Inter-base station cell aggregation means that multiple CCs used by the UE at the same time may be controlled by different base stations.
  • the UE needs to pass two at the same time - Two or more cells and base stations transmit data and signaling, and correspondingly, two or more C-RNTIs are also required, but in the prior art, since the cells participating in the aggregation are co-located, The UE is implemented by the UE, and the base station can ensure that the same C-RNTI is used to transmit data with the UE in the two cells. Therefore, the existing protocol specifies that the UE uses only one C-RNTI when the cell is aggregated within the base station. However, how to configure the C-RNTI of cell aggregation between base stations remains to be solved.

Abstract

La présente invention concerne un équipement d'utilisateur (UE), une station et un procédé d'attribution d'un identifiant temporaire RNTI pour un réseau sans fil, comprenant les étapes suivantes : une première station utilise un premier RNTI pour communiquer avec le premier UE, l'intersection entre un premier ensemble RNTI conservé ou utilisé par la première station et un second ensemble RNTI conservé ou utilisé par une seconde station étant un ensemble vide, et le premier RNTI appartenant au premier ensemble RNTI ; la première station transmet les premières informations à la seconde station, les premières informations étant utilisées pour demander à la seconde station d'utiliser le premier RNTI en vue de communiquer avec le premier UE. Lorsqu'un UE communique avec de multiples stations, un mode de réalisation de la présente invention peut attribuer différents RNTI à l'UE, de sorte que l'UE peut utiliser différents RNTI pour communiquer avec de multiples stations, ce qui résout ainsi le problème d'attribution de RNTI lorsque l'UE communique avec de multiples stations.
