Embodiment
In following detailed description for execution mode, with reference to the accompanying drawing that consists of this paper part.The mode that illustrates by example shows the execution mode that can put into practice the present invention therein.Can be in the situation that do not depart from scope of the present invention and utilize other execution mode and make on structure or change in logic.Therefore, the following detailed description is not construed as limiting the claimed scope of the application.
Be expressed as according to the mode that helps to understand embodiment of the present invention a plurality of discrete operation of carrying out successively with reference to the described various operating processes of flow chart in specification.Yet, flow sequence described here should be interpreted as these operations and must depend on described order.Those skilled in the art can adopt other flow sequence to realize embodiments of the present invention in the situation that do not depart from the scope of the invention, and for example, parallel some process step of execution, merge some process step, segment some process step, etc.
Use hereinafter term " PDCCH of enhancing " to represent any technical scheme for strengthening PDCCH capacity and performance.The term relative with term " PDCCH of enhancing " is " existing PDCCH ", and expression does not have the capacity of enhancing and the existing technical scheme of performance.Term " UE of enhancing " expression has the functional UE of PDCCH of enhancing.The term relative with term " UE of enhancing " is " existing UE ", and expression does not have the functional existing UE of PDCCH of enhancing.
Just as described in the background art, when wireless communication system can support that the PDCCH that strengthens serves for the UE of enhancing with corresponding function, wireless communication system also needed to continue to support that existing PDCCH serves for existing UE.And, being in the consideration of saving Radio Resource, the UE that wireless communication system can also according to circumstances be chosen as specific enhancing adopts the PDCCH that strengthens or does not adopt the PDCCH of enhancing.Therefore, need to provide a kind of technical scheme of controlling the physical downlink control channel of activation/deactivation enhancing in wireless communication system.
A kind of direct solution is, uses Radio Resource to control (Radio Resource Control, RRC) signaling such as the base station of the base station (eNB) of evolution and comes the necessary parameter of PDCCH configuration that strengthens to the UE configuration that strengthens.In case the UE that strengthens receives this RRC signaling, this UE will begin in a minute and detects the PDCCH that strengthens.But this mode has obvious shortcoming: the transmission delay that is caused by the RRC signaling is sizable, may be more than 10ms, and also eNB can not know that the UE of enhancing detects the definite timing of RRC signaling.Therefore, eNB can not determine the timing that begins to distribute for the UE that strengthens the PDCCH that strengthens.If eNB just distributed to it PDCCH that strengthens before the UE that strengthens begins to detect the RRC signaling, will cause the wasting of resources, because the UE that strengthen this moment may not receive the PDCCH of this enhancing.Similarly, if eNB wishes to discharge the PDCCH of enhancing, use the RRC signaling also may cause similar asynchronous problem.
Embodiments of the present invention propose a kind of technical scheme for dispatching the physical downlink control channel that strengthens, make wireless communication system can support activation and/or deexcitation to the physical downlink control channel that strengthens, and can carry out more neatly resource management.

For example can obtain the ability that can subscriber equipment support the PDCCH that strengthens by current RRC signaling procedure (UE capability inquiry) such as the base station of eNB, judge namely also whether particular UE is the UE that strengthens.In one implementation, the eNB physical downlink control channel parameter that can strengthen to its configuration by the RRC signaling when knowing the PDCCH that special user equipment can be supported to strengthen.ENB can reconfigure the parameter that message comes to send to UE the physical downlink control channel that strengthens with the connection of the RRC in current RRC signaling.
Subscriber equipment can be configured according to the physical downlink control channel parameter of this enhancing in order to monitor the physical downlink control channel of this enhancing.In one implementation, the physical downlink control channel parameter of this enhancing comprises at least: the sub-band information of the physical downlink control channel of enhancing.Alternatively, the physical downlink control channel parameter of this enhancing can also comprise following at least one: the physical downlink control channel format information of enhancing; And the physical downlink control channel radio network temporary identifier (RNTI) that is used for enhancing.Wherein, RNTI can be used for making UE identify whether the resource of distributing is the physical downlink control channel resource of distributing to the enhancing of oneself.
In step S120, in response to determining, subscriber equipment is used the physical downlink control channel that strengthens, activate with the first independent order the physical downlink control channel that strengthens to this notification of user equipment.Here, the UE of enhancing will be dispatched with the PDCCH that strengthens in term " activation " expression base station, and this UE will detect one's own physical down link control signal on the PDCCH that strengthens.
According to system's needs, eNB can determine whether and need to activate the PDCCH that strengthens for the UE that strengthens by predetermined standard.For example, whether the eNB capacity that can detect the existing PDCCH of current employing reaches its limit.When reaching the limit of, in order to dispatch more UE (UE and the existing UE that comprise enhancing), can activate the PDCCH that strengthens for UE whole in system or that some of them strengthen.Certainly those skilled in the art's understanding also exists other various situations to determine whether to need to activate as standard the PDCCH that strengthens, and these standards do not limit the applicable of embodiment of the present invention.
