Problems solved by technology

Therefore, as the number of SCCs increases, the PUCCH resource consumption of the PCC increases linearly. In addition, the PUCCH resources themselves are not used for data transmission. In this way, with the linear increase of the PUCCH resource consumption, the uplink throughput supported by the PCC will increase. Decrease sharply, degrading system performance

Embodiment 1

[0221] Embodiment 1: A resource allocation method, which is used for PUCCH resource allocation in a CA scenario. In this CA scenario, one PCC is aggregated with at least two SCCs, and the feedback information of the downlink transport block sent by each SCC is passed through the The PUCCH of the PCC performs feedback, and the method includes:

[0222] Configuring PUCCH resources for the PCC, the PUCCH resources include multiple code channel groups, and each code channel group includes multiple code channel pairs;

[0223] Assign the same code channel group in the above PUCCH resources to two or more SCCs;

[0224] Assigning code channel pairs in the same code channel group to the two or more SCCs, wherein the code channel pairs assigned to the two or more SCCs do not overlap;

[0225] Notify the two or more SCCs of the code channel groups and code channel pairs allocated to them.

Embodiment 2

[0226] Embodiment 2: The method as described in Embodiment 1, said assigning the same code channel group in the above PUCCH resources for two or more SCCs, including:

[0227] When the number of SCCs aggregated with the PCC is greater than the number of code channel groups in the PUCCH resources, the same code channel group in the above PUCCH resources is allocated to two or more SCCs.

Embodiment 3

[0228] Embodiment 3: The method as described in Embodiment 2, the allocation of the same code channel group in the above PUCCH resources for two or more SCCs includes:

[0229] When the number of SCCs aggregated with the PCC is greater than the number of code channel groups in the PUCCH resource and less than twice the number of code channel groups in the PUCCH resource, allocate the same code channel group in the above PUCCH resources for the two SCCs.

Abstract

The invention discloses a method and device for allocating physical uplink control channel resources, including: configuring PUCCH resources for PCC, the PUCCH resources include at least two PUCCH code channel groups, and each PUCCH code channel group includes at least two PUCCH code channels Yes, determine the PUCCH resource allocated to the SCC, at least two SCCs are allocated the same code channel group in the PUCCH resource, and determine the code channel used by the SCC allocated to the same code channel group in the PUCCH resource Yes, so that the code channel pairs used by any two SCCs in the SCCs assigned to the same code channel group in the PUCCH resources do not overlap, so that multiple SCCs can reuse the same PUCCH resources, reducing the number of PUCCH resources. consumption, which improves the utilization rate of PUCCH resources and also improves the system uplink throughput rate.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for allocating physical uplink control channel resources. Background technique [0002] In the development of communication technology, in order to improve the utilization of spectrum resources, CA (English: Carrier Aggregation; Chinese: Carrier Aggregation) technology is introduced in the LTE (English: Long Term Evolution; Chinese: Long Term Evolution) communication system. [0003] The CA technology is a technology for obtaining greater bandwidth by aggregating multiple continuous or discontinuous CCs (English: Component Carrier; Chinese: Component Carrier). The aggregated multiple CCs include one PCC (English: Primary Component Carrier; Chinese: Primary Component Carrier) and at least one SCC (English: Secondary Component Carrier; Chinese: Secondary Component Carrier). Wherein, the carrier initially accessed by the UE is the PCC, and...
