Embodiment Construction

[0032] In view of the above situation where the terminal feedback information confirmation is ambiguous, the embodiment of the present invention provides a feedback information confirmation method and device, which makes full use of the subframe correlation, increases the useful information of the subframe decision, and reduces the uncertain factors that confuse the decision as much as possible. It avoids the impact of completely aggressive and completely conservative algorithms on network performance and user experience, thereby solving the problem that the base station in the prior art cannot effectively confirm whether the feedback information fed back by the terminal is ACK or NACK, and improves carrier aggregation. system performance.

[0033] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the describe...

Abstract

The invention discloses a method and device for confirming feedback information, and the method comprises the steps: receiving ACK / NACK feedback information transmitted by a terminal; determining a reference subframe of a first downlink subframe if the feedback information of the first downlink subframe of M downlink subframes cannot be judged to be ACK or NACK according to the feedback information; and determining whether the feedback information of the first downlink subframe is ACK or NACK based on the statistical probability of ACK in the ACK / NACK feedback information received in a statistical period according to the ACK / NACK feedback information of the reference subframe of the first downlink subframe, mixed automatic retransmission request HARQ information of the first downlink subframe and the reference subframe of the first downlink subframe. The method makes the most of subframe correlation, increases the useful information of subframe feedback judgment, solves a problem that a base station cannot effectively determine whether the feedback information is ACK or NACK in prior art, and improves the performance of carrier aggregation.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for confirming feedback information. Background technique [0002] The enhanced Long Term Evolution-Advanced (LTE-A) system is an evolved version of the Long Term Evolution (LTE). The LTE system performs data transmission based on Hybrid Automatic Repeat reQuest (HARQ), that is, according to the received data The data receiver will correspondingly send the reception status feedback information of correct response (Acknowledged, ACK) or incorrect response (Non-acknowledged, NACK). [0003] In the LTE-A system, in order to support a higher transmission rate, a carrier aggregation (CarrierAggregation, CA) technology is adopted, that is, a larger working bandwidth is obtained by aggregating and transmitting more than two component carriers (ComponentCarrier, CC). Based on CA, the base station sends downlink data to the same terminal on two or more CCs, and...
