Embodiment Construction

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] The sending timing method of the uplink authorization signaling proposed by the present invention is especially used in the uplink TTI bundling working mode. The proposed uplink authorization signaling should ensure a balanced distribution in each downlink subframe, and at the same time, in order to ensure the accuracy of the base station rate prediction, The uplink grant signaling should be as close as possible to its scheduled bonded subframe.

Abstract

The invention provides a method for the timed sending of uplink authorization signaling, which comprises the following steps: acquiring a first uplink subframe from the subframes bound together as a subframe k; setting the uplink authorization signaling into a downlink control channel of the closest subframe before a subframe B, wherein the closest subframe has a downlink time slot, the subframe B is positioned at a subframe position of k-binding size-1, and the binding size refers to the number of the subframes bound together with the subframe k. The invention also provides a device for the timed sending of the uplink authorization signaling. The invention discloses a sending method of the uplink authorization signaling in an uplink TTI bundling transmission mode, and the feedback efficiency of a TDD system is effectively improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for sending timing of uplink authorization signaling. Background technique [0002] Such as figure 1 Shown is the frame structure of the TDD (Time Division Duplex) mode of the LTE (Long Term Evolution, long-term evolution) system. In this frame structure, a 10ms radio frame (wireless frame) is divided into two half Frame (half frame), each half frame is divided into 10 time slots with a length of 0.5ms, two time slots form a subframe with a length of 1ms, and a half frame contains 5 subframes. In this frame structure, the configuration characteristics of the subframe are: [0003] (1) Subframe 0 is fixed for downlink; [0004] (2) Subframe 1 (hereinafter referred to as the special time slot subframe) contains 3 special time slots, which are DwPTS (Downlink Pilot Time Slot, downlink pilot time slot), GP (GuardPeriod, guard interval) and UpPTS (Uplink Pilo...
