Problems solved by technology

[0005] In the prior art, when performing channel detection on PUCCH, it is necessary to detect the data of both time slots, and the amount of data to be processed is large. In the case of a large number of users, if the processing resources are limited, it is difficult to obtain detection on time. result

Embodiment Construction

[0017] In view of the defects in the above-mentioned prior art, the embodiment of the present invention provides a technical solution for PUCCH channel detection. The base station judges whether the current channel quality satisfies the preset condition according to the data of time slot 0, and when the judgment is yes, according to The data in slot 0 of the PUCCH channel is used to detect the PUCCH channel. Through the present invention, the time of PUCCH channel detection can be reduced, and the efficiency of PUCCH channel detection can be improved.

[0018] Since the data mapping of the two time slots (time slot 0 and time slot 1) of the format1\1a\1b PUCCH channel has the same content, when detecting the format1\1a\1b PUCCH, if the channel quality meets certain conditions, the channel In the case of better quality, only the data of time slot 0 can be used for detection, so as to reduce the amount of data to be processed, and the detection result can be obtained one time sl...

Abstract

The invention discloses a method and equipment for detecting a PUCCH (physical uplink control channel). The method comprises the steps: time slot zero data of the PUCCH is received by a base station, and when the base station determines that the quality of a current channel satisfies a preset condition according to the received data, the base station detects the PUCCH only according to the time slot zero data of the PUCCH. The efficiency of detecting the PUCCH can be improved by adopting the invention.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a PUCCH channel detection method and equipment. Background technique [0002] In the LTE (Long-Term Evolution, long-term evolution) system, it is necessary to perform periodic SR (Source Request, resource request) detection for all access users; perform downlink ACK / NACK detection for users with downlink services. Therefore, there are many users that need to perform PUCCH (Physical Uplink Control Channel, physical uplink control channel) processing in one uplink subframe, reaching dozens in some scenarios. However, the eNB (evolved Node B, base station) side requires a limited time to complete the detection. If the detection is completed too late, it will cause a delay in the user's uplink scheduling, and problems such as downlink dissatisfaction. [0003] In the existing technology, when the base station detects the PUCCH channel, it needs to detect and combine t...
