Embodiment Construction

[0097] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings. For clarity of description, PUCCH format 3 will be used to describe the solution in the following, but the solution of the present invention is not limited to the simultaneous transmission of multiple uplink control channel formats being PUCCH format 3, and other PUCCH formats may also be used.

[0098] figure 1 It is a flowchart of a method for determining an uplink control channel resource according to an embodiment of the present invention, such as figure 1 As shown, the method for determining uplink control channel resources in the embodiment of the present invention includes the following steps:

[0099] Step 101, the network side sends a control instruction to the UE.

[0100] When the UE uses N uplink control channel format resource...

Abstract

The embodiment of the present invention discloses a method and device for determining uplink control channel resources. The method includes: when the UE uses N uplink control channel format resources in the same subframe to perform uplink control channel feedback, acquire a single uplink control channel format resource Index, method 1: carrying N uplink control channel format resources in the same PRB pair indicated by a single uplink control channel format resource index; method 2: carrying N uplink control channel format resources in a single uplink control channel format resource In different PRB pairs of the PRB pair indicated by the resource index; Method 3: Part of the uplink control channel format resources among the N uplink control channel format resources are carried in the same PRB pair indicated by a single uplink control channel format resource index , the remaining uplink control channel format resources are borne in other PRB pairs; way 4: N uplink control channel format resources are borne in the PRB pair indicated by multiple resource indexes starting with a single uplink control channel format resource index.

Description

technical field [0001] The present invention relates to uplink control information transmission technology, in particular to a method and device for determining uplink control channel resources. Background technique [0002] In the Long Term Evolution (LTE, Long Term Evolution) system, if the terminal is not allocated uplink resources for UL-SCH transmission, L1 / L2 layer control information such as channel status report, hybrid automatic repeat request (HARQ, Hybrid Automatic Repeat reQuest) feedback, scheduling requests, etc. will be transmitted on the uplink resource specially used to transmit uplink layer 1 / layer 2 (L1 / L2) control information located on the PUCCH. These resources are located at the edge of the total cell available bandwidth. Each such resource contains 12 subcarriers in each slot (slot), ie one resource block (RB). In order to provide frequency diversity gain, these frequency resources perform frequency hopping at the edge of the slot. That is: when th...
