Embodiment Construction

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] The HARQ number calculation method and device provided in this embodiment are mainly aimed at the uncertainty of unscheduled subframes in an RTT when the time slot ratio is 0, which will make it difficult to calculate the HARQ number under TTIBundling, and due to the The technical limitations of the HARQ number acquisition method in the pri...

Abstract

Embodiments of the invention provide an HARQ number computing method and device. The method comprises the following steps: obtaining a current system frame number and a sub-frame number of a current sub-frame, obtaining a remaining HARQ number, and calculating HARQ numbers corresponding to the current system frame number and the sub-frame number of the current sub-frame according to the current system frame number, the current sub-frame number and the remaining HARQ number. The HARQ number computing method and device provided by the embodiments of the invention can be used for well solving the problems of computation of the HARQ number under TTI Bundling when time slot allocation is 0, and ACK processing and virtual ACK processing of a GAP area.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ for short) number calculation method and device. Background technique [0002] In order to enhance the coverage of uplink small-rate services and reduce the delay caused by normal HARQ retransmission, the 3rd Generation Partnership Project (the 3rd Generation Partnership Project, referred to as: 3GPP) introduced the Transmission Time Interval (Transmission Time Interval, referred to as: TTI) bundling (Bundling) The solution of TTIBundling is to bind multiple subframes into one transport block (TransportBlock, referred to as: TB), and send the same TB multiple times on multiple consecutive subframes without waiting for acknowledgment (Acknowledgment, referred to as: ACK) / Negative Acknowledgment (NACK for short): Different redundant versions corresponding to the same TB ...
