Description
Technical field
The present invention relates to wireless communication technology field, more particularly to it is a kind of according to QoS distribute PUCCH resource method and
System.
Background technique
In existing LTE communication system, cell is to UE (User Equipment, user equipment) points in connection status
With PUCCH (Physical Uplink Control CHannel, physical uplink control channel) resource, for feeding back UE
CQI (Channel Quality Indicator, channel quality instruction), PMI (the Precoding Matrix of downlink measurement
Indicator, pre-coding matrix instruction), the ACK/ of SR (Scheduling Request, scheduling request) and descending scheduling
The feedback of nack message.The PUCCH resource agreement of LTE communication system has specific regulation, and the quantity of PUCCH resource is no more than
The 25% of uplink total resources number, therefore on-line UE counts up to the quantity for being limited by PUCCH resource entirely.
PUCCH resource distribution was carried out according to the period, and the period is shorter, and UE is more accurate to the measurement for channel of eating dishes without rice or wine, the UE institute
The PUCCH resource needed is also more；Otherwise the period is longer, and PUCCH resource required for the UE is fewer, the down channel of measurement
Quality does not have real-time more yet.
The strategy of existing PUCCH resource distribution is, according to a series of thresholding of on-line UE number setting in cell, and
The assignment period of PUCCH resource is associated with these thresholdings.In brief, the assignment period of PUCCH resource, with online in cell
The increase of UE number and increase, in this way realize UE downlink measurement cell specification between balance.But it will lead to industry in this way
Service type needs downlink measurement that can not obtain enough PUCCH resources than more frequently UE, and type of service needs downlink to survey
It measures fewer UE and but obtains extra PUCCH resource.
