Abstract

The invention discloses a method and a device for resolving a control message of a physical uplink shared channel. The method comprises the following steps of: performing primary acquiring, namely acquiring a rank indication (RI) message of each control message in multiple control messages of the physical uplink shared channel and storing; determining, namely determining channel quality information (CQI) length of each control message by using the RI message; performing secondary acquiring, namely performing CQI de-interleaving and resolution on the control message with the determined CQI message length, and acquiring the CQI message of the control message; and combining, namely combining the acquired CQI message of the control message and the stored RI message of the control message again, wherein the primary acquiring step and the determining step are performed concurrently and the secondary acquiring step and the combining step are performed concurrently. By the method and the device, the performance of resolving the control message of the physical uplink shared channel by a system can be enhanced, the resolution delay of the control message can be reduced and the whole processing performance can be improved.

Description

technical field

[0001] The present invention relates to the communication field, in particular, to a 3GPP (3 rd Generation partnership project, third generation mobile communication partnership project) PUSCH (Physical Uplink Shared Channel, uplink traffic channel) control information (hereinafter referred to as control information) analysis method and device in LTE (Long Term Evolution, long-term evolution) system. Background technique

[0002] The LTE protocol stipulates that in the aperiodic reporting mode, the information encoding method and process of the control information of the user equipment transmitter are: channel encoding is performed on the RI (Rank Indication, matrix rank indication) of the current user, and at the same time, it is performed according to the value of the RI before encoding. The CQI (Channel Quality Information, Channel Quality Indication) original information length is selected, based on which the CQI information is encoded, and finally the e...

Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] The inventor found through research that, in the process of analyzing the RI information in the received uplink traffic channel control information (including RI information and CQI information) at the receiving end, whether it is de-interleaving, demodulation, descrambling or de-channel coding, They are not interfered by other processing results of the user terminal, and have good independence. The following embodiments take advantage of this independence to perform parallel processing on the RI information deinterleaving and analysis of multiple uplink traffic channel control information of multiple user terminals and the determination of the length of CQI information, and then perform multi...
