Embodiment Construction

[0106] In the embodiment of the present invention, for a terminal that needs to be scheduled within the current TTI (Transmission Time Interval, sending time interval), according to the DCI of the terminal, determine the CCE aggregation degree corresponding to the terminal; according to the preset CQI and coding rate Correspondence, determine the coding rate corresponding to the CQI of the specific subband of the terminal, where the specific subband is a subband selected from all subbands corresponding to all subband CQIs reported by the terminal; according to the determined The coding rate of the terminal adjusts the CCE aggregation degree corresponding to the terminal; after adjusting the CCE aggregation degree corresponding to each terminal that needs to be scheduled in the current TTI, according to the adjusted The CCE aggregation degree corresponding to the terminal, and the control channel resource is configured for each terminal. After the embodiment of the present inve...

Abstract

The invention discloses a method and a device for configuring control channel resources, for solving the problem that in the prior art a base station determines a CCE aggregation degree of each piece of DCI according to a broadband CQI reported by a terminal, and thus the determined CCE aggregation degree is imprecise. The method provided by the invention comprises the steps of determining the CCE aggregation degree corresponding to the terminal according to the DCI of the terminal aiming at the terminal needing to be scheduled in a current TTI; according to a preset correspondence between the CQI and a coding rate, determining the coding rate corresponding to the CQI of a specific sub-band of the terminal; according to the determined coding rate of the terminal, adjusting the CCE aggregation degree corresponding to the terminal; and after adjusting the CCE aggregation degree corresponding to each terminal needing to be scheduled in the current TTI, configuring control channel resources for each terminal according to the adjusted CCE aggregation degree corresponding to each terminal. By using the method provided by the invention, the adjusted CCE aggregation degree is more precise.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and equipment for configuring control channel resources. Background technique [0002] At present, for the configuration of the PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) symbol number of the base station, it is globally configured according to a unified template when the station is opened. The configuration of all base stations is consistent, or only by urban area, In the suburban area, base stations are simply distinguished, and different numbers of PDCCH symbols are configured for the distinguished base stations. [0003] When the terminals under the base station need to be scheduled, the base station determines the CCE (Control Channel Element, control channel unit) aggregation degree, wherein the CCE aggregation degree includes: 1, 2, 4, and 8, and the base station configures control channel resources for the...
