Abstract

The invention discloses a PUCCH resource allocation method and device for solving the problem of resource waste or service failure easily caused by bad flexibility of the PUCCH resource allocation method in the prior art. The method comprises the following steps: a base station selects second terminal equipment with allocated PUCCH format 3 resource when determining that the accessed first terminal equipment is the first kind of terminal equipment or the second kind of terminal equipment and determines that the resource quantity of the to-be-allocated PUCCH format 3 resource is zero, and allocates the released PUCCH format 3 resource to the first terminal equipment after releasing the PUCCH format 3 resource of the second terminal equipment.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a physical uplink control channel (PhysicalUplink Control Channel, PUCCH) resource allocation method and device. Background technique [0002] PUCCH is used to transmit uplink control information, such as SRI (Scheduling Request Information, scheduling request information), CSI (Channel State Information, channel state information), and HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat request) ACK (Acknowledgment , confirmation response) / NACK (Nacknowledge, non-confirmation response) feedback information, etc. In a Long Term Evolution (LTE) network supporting carrier aggregation (Carrier Aggregation, CA), the base station needs to allocate PUCCH format 3 (format 3) resources or PUCCH format 1b (format 1b with channel selection, 1b-cs) resources with channel selection, to ensure the HARQ ACK / NACK feedback of the terminal equipment. Among them, ...
