Embodiment 1

[0054] Assume that in an LTE uplink system, the index number of PUCCH resources reserved for transmission of SRI is N PUCCH，SRI , the repetition periods of the PUCCH resources used to transmit the SRI in this system are 1 ms, 2 ms, 5 ms, 10 ms, 20 ms and 40 ms.

[0055] First establish a PUCCH resource table set for transmitting SRI, and each PUCCH resource in the PUCCH resource table uses a time-frequency domain index combination Identify and determine the frequency domain index n according to the number of PUCCH resources reserved for transmitting SRI PUCCH，SRIThe value range is 0~N PUCCH，SRI -1; determine the time domain index I according to the PUCCH resource repetition period used to transmit SRI in the system PUCCH，SRI The maximum value of is the least common multiple of 40 of the various repetition periods of the PUCCH resources used to transmit SRI in this system, so I PUCCH，SRI The value range is 0-39.

Abstract

The invention discloses an uplink control channel resource distribution method and device. The method comprises the following steps of: establishing a physical uplink control channel (PUCCH) resource table corresponding to uplink control information, wherein a time domain index of a PUCCH resource is set to be the minimum common multiples of various PUCCH repeated cycles supported by the PUCCH resource for transmitting the corresponding uplink control information; and during distribution of the PUCCH resource, finding out an available resource according to the resource table and the PUCCH repeated cycle of a current terminal, finding out an available resource within a range according to the resource table and a smaller PUCCH repeated cycle, and distributing the PUCCH resource to the current terminal according to the search results. Therefore, when the PUCCH resource is distributed to the terminal, the PUCCH repeated cycle of the terminal is considered, and the smaller PUCCH repeated cycle is also considered; under the condition that the uplink control channel resources in different cycles coexist, the transmission requirement of the current terminal can be met and the utilization rate of the uplink control channel resources is increased; and meanwhile, the resources can be selected according to the resource table designed by the embodiment of the invention, so the technology implementation is simplified.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for allocating uplink control channel resources. Background technique [0002] In order to support the normal operation of the uplink and downlink shared channel, UE (User Equipment, terminal) needs to send some control information related to uplink and downlink data transmission to the base station, that is, uplink control information (Uplink Control Information, UCI). In the LTE (Long Term Evolution, Long Term Evolution) system, the base station fully controls the behavior of the UE. The UE needs to receive the scheduling information sent by the base station, send and receive uplink and downlink data according to the instructions of the scheduling information, and feed back related control information. . [0003] The LTE system uses PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) to transmit uplink control information. ...
