Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that the resources reserved for semi-static ACK / NACK, SRI and CQI cannot be rationally configured in the prior art, but the resource size reserved for semi-static ACK / NACK, SRI and CQI It has a great influence on the performance of LTE communication system
If too few resources are reserved, resources will be limited, causing the system to frequently send messages to users that the resources of the communication system are limited
If too many resources are reserved, PUCCH resources will be wasted

Embodiment Construction

[0026] The LTE communication system supports configuring the number of channels reserved for semi-static ACK / NACK and SRI and the number of resource blocks (Resource Block, RB for short) reserved for CQI under different system bandwidths. Such as figure 1 As shown in , it is a schematic diagram of the arrangement of PUCCH resources. according to figure 1 In the prior art, when dynamic ACK, semi-static ACK / NACK, SRI and CQI resources are allocated on the PUCCH, fixed resource blocks (Resource Blocks, hereinafter referred to as: RB) at both ends of the PUCCH bandwidth are reserved for CQI, such as figure 1 Shown in 101 and 102. Then a fixed number of subchannels are reserved for semi-static ACK / NACK and SRI adjacent to the RB allocated to CQI, as shown in Figures 103 and 106 . figure 1 104 and 105 represent resources allocated to dynamic ACK / NACK, and 107 represents a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH for short).

Abstract

One embodiment of the invention discloses a method and a device for configuring a physical uplink control channel resource, and a base station. The method comprises: when ACK / NACK and SRI and unused resource amount in the resource reserved for CQI are bigger than the sum of a first preset value and a first amount, respectively reducing the first amount and a second amount for the semi-static ACK / NACK and the SRI and the resource reserved for the CQI; and when occupancy factor of the resource reserved for the semi-static ACK / NACK and the SRI is bigger than a second preset value, or the amount of the unused resource amount in the resource reserved for the CQI is smaller than or equal to a third preset value, increasing a third amount for the resource reserved for the semi-static ACK / NACK and the SRI, and increasing a fourth amount for the resource reserved for the CQI. The embodiment of the invention can reasonably configure the resource reserved for the semi-static ACK / NACK and the SRI and the CQI in PUCCH, so as to improve performance of a communication system.

Description

technical field [0001] The present invention relates to communication technology, in particular to a physical uplink control channel (Physical Uplink Control Channel, hereinafter referred to as: PUCCH) resource configuration method and device, and a base station. Background technique [0002] In the Long Term Evolution (hereinafter referred to as: LTE) communication system, the uplink control signaling sent by the user terminal to the base station on the PUCCH includes an acknowledgment / no acknowledgment (hereinafter referred to as: ACK / NACK) message, Scheduling Request Indicator (Scheduling Request Indicator, hereinafter referred to as: SRI) and channel quality information (Channel Quality Information, hereinafter referred to as: CQI). Among them, ACK / NACK is used to feed back the reception result of Hybrid Automatic Repeat Request (HARQ) to the base station; SRI is used to request uplink resource scheduling to the base station; CQI is used to feed back the downlink channel...
