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 with the uplink reception of the entire LTE physical layer, and designs an efficient parallel reception system, which can effectively resolve conflicts generated during multi-channel configuration, and implement conflict arbitration and separation mechanisms. In the specific processing process of each channel In this way, you don't need to care about the conflicting channel, which improves the processing efficiency of each channel, 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 relatively complicated PUCCH in the uplink, since there are conflicts and multiplexing problems of various control information, the optimization scheme of this embodiment reduces the detour of the internal monitoring, which can improve the detection efficiency and processing capability of the PUCCH. .

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

Abstract

The invention discloses an uplink receiving method and device, comprising: after the uplink receiver receives air interface data, each channel processing subsystem and signal processing subsystem is in a ready state, and the channel tasks and / or signal tasks are respectively sent to The corresponding channel processing subsystem and / or signal processing subsystem performs demodulation processing; the channel processing subsystem and signal processing subsystem process the received tasks in parallel. The uplink receiving method of the present invention can realize high-efficiency parallel uplink reception, reduce the correlation degree of each channel in the LTE uplink receiving system and the correlation of each channel in the PUCCH, reduce system complexity, and improve uplink reception processing efficiency.

Description

technical field [0001] The present invention relates to LTE (Long Term Evolution, long term evolution), and 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) and the like. [0003] The PUCCH channel is responsible for the periodic reporting of uplink control information. The control information includes HARQ-ACK (HybridAutomatic Repeat request-Acknowledgement), SR (SchedulingRequest, scheduling request), and CQI (Channel Quality Indication, channel quality indication). ), PMI (PrecodingMatrix Index, precoding matrix indication), RI (Rank Indication, rank indication) and the like. [0004] PUSCH is responsible for carrying service information and also carrying control information. [00...
