Embodiment Construction

[0055] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0056] figure 2 A flow chart showing a method for expressing confirmation information for detecting DTX according to an embodiment of the present invention, including the following steps:

[0057] Step S10, the UE feeds back ACK / NACK confirmation information for each downlink subframe from the base station, and performs an AND operation on the ACK / NACK confirmation information to obtain AND confirmation information;

[0058] Step S20, the UE maps the number of downlink subframes to corresponding positions according to the rules;

[0059] Step S30, the UE constructs an uplink subframe, and sets the confirmation information in the PUCCH corresponding to the uplink subframe;

[0060] In step S40, the UE feeds back the uplink subframe to the base station, so as to inform the base station whether there is an error in receiving the down...

Abstract

The present invention provides a confirmation information presenting method which is used for detecting DTX. The method comprises the following procedures: feeding back an ACK / NACK confirmation information by an UE aiming at each descending sub-frame from the base station, and executing and-operation to these ACK / NACK confirmation information to obtain the and-confirmation information; mapping the number of the descending sub-frame to a corresponding direction by the UE according to a regulation; constructing an ascending sub-frame by the UE and setting the and-confirmation information in the PUCCH of the corresponding position of the ascending sub-frame; and feeding back the ascending sub-frame by the UE to the base station to inform whether an error exists in the receiving of the descending sub-frame to the base station through the corresponding position of PUCCH and the value of the confirmation information. The invention also provides an UE and a base station. The invention guarantees the whole and effective transmission of the descending data.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for expressing confirmation information for detecting DTX, a UE and a base station. Background technique [0002] figure 1 Shows the frame structure of the LTE (Long Term Evolution, long-term evolution) system TDD (Time Division Duplex, time division duplex) mode, in this frame structure, a 10ms radio frame (wireless frame) is divided into two half frames (half frame), each half frame is divided into 10 time slots with a length of 0.5 ms, and two adjacent time slots form a subframe with a length of 1 ms. One field contains 5 subframes. For Normal CP (Normal Cyclic Prefix, standard cyclic prefix), a slot contains 7 symbols with a length of 66.7μs, of which the CP length of the first symbol is 5.21μs, and the CP length of the remaining 6 symbols is 4.69μs; for Extended (Extended, extended) CP, one time slot includes 6 symbols, and the CP length of all symbols is 16.67 ...
