Description

A kind of uplink and downlink federated resource distribution method
Technical field
This application involves mobile communication technology field more particularly to a kind of uplink and downlink federated resource distribution methods.
Background technology
In wireless communication system, in order to accurately and efficiently be communicated between base station and user equipment (UE), UE needs anti-to base station Present ascending control information (Uplink Control Information, UCI).Ascending control information includes：Scheduling request indicates (Scheduling Request Indicator, SR)；Confirm/deny response (Acknowledgement/Negative- Acknowledgement, ACK/NACK)；Channel quality indicates (Channel Quality Indicator, CQI), order instruction (Rank Indicator, RI) and pre-coding matrix instruction (PrecodingMatrix Indicator, PMI).Wherein, SR is used In UE to base station requests ascending resource, ACK/NACK is used for UE to base station indicating downlink data receiver correctness, the information such as CQI The down channel quality measured to base station instruction for UE.
In LTE system, base station is that UE is assigned with special Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH) resource is used for transmission tri- kinds of above-mentioned SR, ACK/NACK and CQI/RI/PMI control information.It presses According to the regulation of current LTE protocol, the resource index that CQI resource indexes, semi-static ACK/NACK and SR are occupied passes through RRC information half Static configuration, the resource index that dynamic ACK/NACK is occupied need to be according to its corresponding downlink dynamic dispatching PDCCH occupied the One control unit (CCE, Control Channel Element) resource index is calculated, i.e., PUCCH indexes are equal to CCE Index adds certain offset, and this implicit correspondence saves the expense of additional signaling.
Meanwhile agreement it further provides that ACK/NACK feedback in addition to occupy by the corresponding dynamic PUCCH resource of CCE indexes other than, when ACK/NACK and CQI/PMI or SR message reports simultaneously, can be reported by the resource location of CQI/PMI or SR；When UE is at certain When sub-frame of uplink there are PUSCH resources, then all information carried are needed all to pass through PUSCH on not simultaneous transmission PUCCH, PUCCH Resource carrying reports.
LTE protocol also defines the mapping method that PUCCH resource indexes Physical Resource Block (PRB).As shown in Figure 1, being The schematic diagram that PUCCH resource block to physical resource block maps in one subframe has reserved 4 resource blocks in the figure for PUCCH, point Not Wei m=0,1,2,3, one of PUCCH resource block is located at available in the PRB resources of two time slots of a subframe The both ends of frequency spectrum resource.PUCCH is placed on to the both ends of available resources, is used for intermediate monoblock frequency spectrum resource to transmit PUSCH, both It effectively can utilize frequency spectrum resource that can keep the single-carrier property of uplink again, while can preferably obtain PUCCH differences Frequency diversity gain between time slot.
It will be seen from figure 1 that keeping for the resource size of PUCCH to have a great impact the performance of LTE system, if in advance It stays too much, system spectral resources can be wasted, cause PUSCH resources less, influence throughput of system；If reserved very little, can make At user resource limit, causes user that cannot report CQI information or transmission SR requests etc. in time, influence system performance.
There are mainly two types of existing LTE system PUCCH resource allocation plans：
Scheme one：The priority processing downlink business resource allocation in a scheduling subframe, completes all downlinks of this subframe After scheduling, then uplink service resource allocation is carried out, and the ACK/NACK according to the user of downlink actual schedule in sub-frame of uplink Resource quantity is occupied, determines the available resources of PUSCH；When uplink and downlink are dispatched, it is based respectively on the subscriber channel of respective link direction The factors such as quality, portfolio, transmission rate select user to carry out resource allocation；
Scheme two：Semi-static planning and reserved method are carried out for PUCCH resource, plans that a part of resource is used in advance CQI/RI/PMI, SR and the ACK/NACK of PUCCH is reported, and is counted in a period of time, when reserved resource utilization is too low Or when excessively high, then reserved resource quantity is adjusted.
There are the following problems for existing LTE system PUCCH resource allocation plan：
In scheme one, PUCCH resource quantity is by preconfigured CQI/RI/PMI and SR periods and downlink transfer Maximum CCE indexes corresponding to the PDCCH symbolic numbers of subframe determine, it is difficult to the characteristics of making full use of PUCCH periodic resources, with And PUSCH carries the characteristics of ACK/NACK is fed back with road, and the ACK/NACK testing results of downlink traffic transmission can be caused to report and accounted for With more PUCCH resource, PUSCH available resources quantity is made to reduce, is reduced so as to cause uplink throughput；
In scheme two, certain resource quantity is reserved by semi-static mode, after a period of time according to service efficiency into Row adjustment, can not be flexibly adapted to the change of user and business demand in system, if resource quantity is reserved and more can be caused PUCCH resource wastes, it is reserved less and can cause the ACK/NACK of certain user report position and PUSCH resource contentions or certain The problem of a little users are unable to get scheduling.
Invention content
This application provides a kind of uplink and downlink federated resource distribution methods, can reduce and pass through to the full extent The ACK/NACK quantity that PUCCH dynamic resources carry occupies resource quantity to reduce PUCCH, and money can be used by increasing PUSCH Source amount brings uplink throughput to be promoted.
