Problems solved by technology

[0006] While defining channels and signals, the protocol also stipulates related constraints. For example, PUSCH and PUCCH cannot exist at the same time. If control information needs to be transmitted, and the UE (User Equipment, user equipment) within TTI (Transmission Time Interval, transmission time interval) If there is no PUSCH, the control information is transmitted by PUCCH, otherwise it is transmitted on PUSCH; when PUCCH and PUSCH are processed, if there is SRS, the resources of SRS should be reserved. Under these constraints, there is no better way to realize it. Uplink receiving efficiency is the highest

Embodiment Construction

[0073] This embodiment starts from the uplink reception of the entire LTE physical layer, and designs an efficient parallel reception system, which can effectively resolve the conflicts generated during multi-channel configuration, and realize the conflict arbitration and separation mechanism. In the specific processing process of each channel In , you don't need to care about the channels that conflict with it. This method improves the efficiency of each channel processing, and also facilitates the separation of each channel and the realization of parallel processing of subsystems. At the same time, for the processing of the more complicated PUCCH in the uplink, since there are conflicts and multiplexing problems of various control information inside it, the optimization scheme of this embodiment reduces the detour of its internal monitoring, and can improve the detection efficiency and processing capacity of PUCCH .

[0074] In addition, this embodiment not only solves the p...

Abstract

The invention discloses an uplink receiving method and device. The uplink receiving method includes the steps of enabling channel processing subsystems and signal processing subsystems to be in the ready state after an uplink receiver receives wireless interface data, respectively sending channel tasks and / or signal tasks to the corresponding channel processing subsystems and / or signal processing subsystems for demodulation processing, and enabling the channel processing subsystems and the signal processing subsystems to process the received tasks in a parallel mode. According to the uplink receiving method, uplink efficient parallel receiving can be achieved, the association degree of channels in an LTE uplink receiving system and association of the channels in a PUCCH are reduced, the system complexity is reduced, and the uplink receiving processing efficiency is improved.

Description

technical field [0001] The present invention relates to LTE (Long Term Evolution, long term evolution), in particular to an uplink receiving method and device. Background technique [0002] In the LTE system, uplink physical channels / signals include SRS (Sounding Reference Signal, sounding reference signal), PUSCH (Physical Uplink Shared Channel, physical uplink shared channel), PUCCH (Physical Uplink Control channel, uplink control channel), etc. [0003] The PUCCH channel is responsible for the periodic reporting of uplink control information. The control information includes HARQ-ACK (Hybrid Automatic Repeat request-Acknowledgment, hybrid automatic repeat request-acknowledgement), SR (Scheduling Request, scheduling request), CQI (Channel Quality Indication, channel Quality Indication), PMI (Precoding Matrix Index, Precoding Matrix Indication), RI (Rank Indication, Rank Indication), etc. [0004] The PUSCH is responsible for carrying service information and also carrying ...
