Abstract

The embodiment of the invention provides a method and a device for allocating downlink control channel resources. The method comprises steps: PDCCH resources in a carrier aggregation cluster are allocated, and a first uplink PDCCH resource for each uplink carrier and a downlink PDCCH resource for a downlink carrier are acquired; according to an acquired user equipment priority order, uplink scheduling is carried out on the first uplink PDCCH resource for the uplink carrier or downlink scheduling is carried out on the downlink PDCCH resource for the downlink carrier until the uplink scheduling or the downlink scheduling is completed. The carrier aggregation cluster comprises one downlink carrier and at least two uplink carriers. Aggregation of one downlink carrier and multiple uplink carriers realizes scheduling on a large amount of uplink service, and an application scene with a large amount of uplink service requirements can be met.

Description

technical field [0001] Embodiments of the present invention relate to signal processing technologies, and in particular to a method and device for allocating downlink control channel resources. Background technique [0002] In the current Long Term Evolution (English: Long Term Evolution, LTE for short) system, a single carrier supports a maximum system bandwidth of 20M. If a larger bandwidth needs to be supported, a carrier aggregation technology is required. [0003] In the existing 3rd Generation Partnership Project (English: 3rdGenerationPartnershipProject, referred to as: 3GPP) protocol, the aggregation of a maximum of 5 carriers can be realized, and the number of downlink carriers is required to be greater than or equal to the number of uplink carriers. Carrier aggregation In terms of technology, each carrier aggregation cluster includes one uplink carrier and more than or equal to two downlink carriers. Aggregation provides greater downlink bandwidth, which effectivel...
