Title:
SENDING AND RECEIVING METHOD AND APPARATUS FOR DOWNLINK COMMON CHANNEL
Document Type and Number:
WIPO Patent Application WO/2016/141845
Kind Code:
A1
Abstract:
Disclosed are a sending and receiving method and apparatus for a downlink common channel, which are used for decreasing interference with a downlink common channel with a frequency-domain sending position fixed at a full bandwidth stationary position. The method comprises: a network side obtains, according to a network side interference measurement value and terminal side interference level indication information, an average interference level difference value of a user equipment; judge whether the average interference level difference value is greater than a set first threshold value or not; if so, group pre-set frequency-domain candidate positions, and send the downlink common channel successively on each group of candidate positions at a sending moment by adopting a frequency hopping way; and otherwise, select N candidate positions from the pre-set frequency-domain candidate positions, and send the downlink common channel on the N candidate positions at the sending moment. Therefore, the interference problem of other communication systems on a same frequency band and the manmade malicious interference problem are solved, thereby effectively decreasing the interference on the channel with a frequency-domain resource mapping position fixed at a full bandwidth stationary position.
