Embodiment Construction

[0074] The DTX judgment method, device and base station of the physical uplink control channel provided by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0075] The embodiment of the present invention provides a DTX judgment method for discontinuous transmission of a physical uplink control channel, such as figure 1 Shown, including:

[0076] Step 101: The base station receives the uplink signal in the physical uplink control channel PUCCH resource block of the target UE at the first moment.

[0077] Specifically, the base station receives the uplink signals of all UEs at the first moment, and extracts the uplink signals carried in the PUCCH resource block of the target UE from the uplink signals of all UEs. The uplink signal carried in the PUCCH resource block of the target UE may include PUCCH signal and noise, or may only include noise.

[0078] Step 102: When it is determined that the physical uplink sha...

Abstract

The present invention provides a DTX judging method, device and base station of a physical uplink control channel. The method includes: the base station receives the uplink signal in the PUCCH resource block of the target UE at the first moment; determines that the PUSCH sent by the target UE is received at the second moment signal, perform channel estimation on the uplink signal according to the preset algorithm to obtain the channel estimation frequency domain result sequence HPUCCH, and perform channel estimation on the PUSCH signal according to the preset algorithm to obtain the channel estimation frequency domain result sequence HPUSCH, and the second moment is before the first moment ; Determine the DTX judgment result of the target UE at the first moment according to the HPUCCH sequence, the HPUSCH sequence and the preset DTX threshold. The present invention improves the accuracy of DTX judgment of the PUCCH channel to a certain extent, and can more accurately judge the DTX state of the target UE even in an environment with severe interference.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a DTX judgment method, device and base station of a physical uplink control channel. Background technique [0002] At present, in the Long Term Evolution (LTE) system, when the user terminal has no data to transmit on the Physical Uplink Shared Channel (PUSCH), it uses the Physical Uplink Control Channel (PUCCH) to send data. Transmission of uplink control information. Among them, each user terminal occupies multiple resource indexes on the PUCCH domain, and one RB (Resource Block) in the PUCCH domain occupies 12 subcarriers, which are distributed on two time slots in a subframe, and each time slot The positions of the occupied subcarriers are different. Different user terminals in the same cell can occupy different resource indexes of the same RB, through orthogonal code n oc And cyclic shift within code n cs Reuse. [0003] In an ideal situation, all user termin...
