Embodiment Construction

[0031] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principles of the present invention.

[0032] first combined with figure 1 with 2 The method described in the embodiment of the present invention is described in detail.

[0033] The method described in the embodiment of the present invention mainly includes: after completing the downlink or uplink scheduling, the sending end of the ARQ status report judges whether there is remaining air interface bandwidth, and when it is determined that there is and is greater than the first predetermined bandwidth value, constructs an ARQ status report; judges whether there is remaining air interface bandwidth Whether the bandwidth satisfies the requirement for sending the ARQ status report, and if so, ...

Abstract

The invention discloses a method and device for triggering and constructing an ARQ status report for an automatic retransmission request, wherein the method includes: after completing downlink or uplink scheduling, the sender of the ARQ status report judges whether there is remaining air interface bandwidth, and when it is determined that there is and is greater than the first When a predetermined bandwidth value is reached, trigger the construction of an ARQ status report; judge whether the remaining air interface bandwidth meets the sending requirements of the ARQ status report, if satisfied, then send the ARQ status report, otherwise cancel sending the ARQ status report; Based on this, the timeliness of the ARQ status report is further improved, and the retransmission delay of the ARQ is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for triggering and constructing an automatic repeat request status report. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, for reliable data transmission, the ARQ (Automatic Repeat-Request, automatic repeat request) function is introduced. The ARQ function is divided into a sending end and a receiving end. Send the ARQ status report of data reception under certain conditions to the sending end, which includes information about which data is received normally and which data is not received, and the sending end (ie, the receiving end of the ARQ status report) sends The status report sent by the terminal) is used for data retransmission, so as to achieve the purpose of reliable transmission. Since the ARQ status report will directly affect the ARQ data retransmission time, and further affect the delay and jitter...
