Description

A kind of distribution method of physical layer control channel resource and device
Technical field
The present invention relates to the resource allocation techniques in Long Term Evolution (LTE) system, relate in particular to a kind of distribution method and device of physical layer control channel resource.
Background technology
In wireless communication system, the definition ubiquity of control channel, its effect generally comprises transmitting broadcast information, Signalling exchange information and to auxiliary control information of business information etc.Wherein, to the auxiliary control information of business information as: in service data scheduling control information, mixed automatic retransfer request (HARQ, Hybrid Automatic Repeat Request) technology to the confirmation of traffic channel transmission data/non-confirmation (ACK/NACK) feedback message etc.
3G (Third Generation) Moblie Long Term Evolution (LTE, Long Term Evolution) in system, control channel still exists, and be defined as Physical Downlink Control Channel (PDCCH in physical layer, Physical Downlink Control Channel), Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel).PDCCH mainly completes scheduling controlling, the power of up-downgoing business datum and controls adjustment etc.; PUCCH mainly completes dispatch request (SR, Scheduling Request) ascending resource request, ACK/NACK feedback and channel quality indication (CQI, Channel Quality Indicator)/pre-coding matrix indication (PMI, Precoding Matrix Indicator)/grade is indicated the feedback of (RI, Rank Indication) information etc.Wherein, for the PUCCH resource of SR and CQI/PMI/RI information feedback, distribute, be defined as by Radio Resource control (RRC, Radio Resource Control) high level and distribute unitedly in LTE system, the mode that the resource of PUCCH retains in advance completes; And for ACK/NACK feedback, consider its dynamic characteristic, PUCCH resource need be carried out dynamic assignment.
Current agreement regulation, under above-mentioned ACK/NACK feedback, the distribution of PUCCH resource dynamic is adopted with the following method: consider that the up-downgoing of ACK/NACK feedback has certain corresponding characteristic, dynamically the ACK/NACK of downlink service data feedback all needs a corresponding PDCCH downlink service data scheduling to trigger each time; Therefore, regulation is carried out first control channel unit (CCE that the PUCCH resource of ACK/NACK feedback need to be shared according to the descending dynamic dispatching PDCCH of its correspondence, Control Channel Element) resource index is determined, wherein, descending dynamic dispatching PDCCH and all the other type PDCCH are unified in the indicated CCE resource of Physical Control Format Indicator Channel (PCFICH, Physical Control Format Indication Channel) and distribute.
Consider the particularity that only has the shared CCE resource index of descending dynamic dispatching PDCCH to distribute for the PUCCH resource of uplink ACK/NACK feedback, if according to the current method of agreement by descending dynamic dispatching PDCCH and all the other type PDCCH mixed allocation in unified CCE resource, its deficiency is: all the other type PDCCH(are as uplink service channel dispatch PDCCH type etc.) also can take corresponding CCE resource index, and it does not need PUCCH feeding back ACK/NACK.Therefore, along with all the other type PDCCH are to the taking of CCE resource, can phase strain large for the PUCCH resource span of uplink ACK/NACK feedback, thus cause the wasting of resources of PUCCH resource in distributing.
Thus, be necessary to propose a kind of scheme of distributing based on LTE physical layer control channel resource that can effectively avoid PUCCH resource to distribute waste.
