Embodiment Construction

[0073] By adopting the technical scheme of the invention, the problem of inaccurate DTX judgment results caused by the traditional DTX judging method in the prior art can be effectively avoided.

[0074] An embodiment of the present invention provides a method for judging DTX of an uplink control channel, and preferred implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0075] refer to figure 1 As shown, the specific processing flow of a DTX judgment method for an uplink control channel provided by an embodiment of the present invention includes:

[0076] Step 101: Determine the number of ACK / NACKs or the number of SRs fed back by the current user in the current uplink subframe.

[0077] In the uplink subframe, ACK / NACK or SR can be fed back, or ACK / NACK and SR can be fed back at the same time.

[0078] Specifically, the number of ACK / NACKs fed back by the current user in the current uplink subframe...

Abstract

The invention discloses a DTX judging method and device of an uplink control channel, which are used to solve the problem in the prior art that the traditional DTX judging method leads to inaccurate DTX judging results. The method is: determining the number of ACK / NACKs or the number of SRs fed back by the current user in the current uplink subframe; Describe the SINR value of the current user, and determine the DTX judgment threshold value, and determine the DTX judgment response result of the current user according to the SINR value and the DTX judgment threshold value. In this way, the DTX judgment is adjusted based on the load of the cell, the SINR value of the current user and the DTX judgment threshold value can be calculated more accurately, and finally the DTX judgment result can be obtained accurately.

Description

technical field [0001] The present invention relates to the communication field, in particular to a DTX judging method and device of an uplink control channel. Background technique [0002] Currently, in the Long Term Evolution (LTE) system, when the user terminal has no data to send on the Physical Uplink Shared Channel (PUSCH), the physical uplink control channel (Physical Uplink Control Channel, PUCCH) is used to send Transmit uplink control information. Wherein, each user terminal occupies a resource index in a resource block (Resource Block, RB) on a PUCCH domain, and an RB in the PUCCH domain occupies 12 subcarriers, which are distributed on two time slots in a subframe, and The positions of the subcarriers occupied by each time slot are different. Different user terminals in the same cell can occupy different resource indexes of the same RB, through the orthogonal code n oc and cyclic shift n in the code cs for multiplexing. [0003] Ideally, all user terminals i...
