Problems solved by technology

[0004] For the timing processing of UE terminals, the usual technical solutions are only applicable to single-processor architecture, and one TPU (Time Processing Unit, time control unit) can only serve one processor; and the interrupt granularity only supports the time slot level, and the accuracy is not high. High; it can only passively respond to the switching interruption of other mode basebands, and cannot actively obtain the MRTR (Mobile Radio timing Reference, mobile radio clock reference) time of other mode basebands, and has application limitations in multi-mode expansion

Abstract

The invention discloses a timing processing device and method, applied to a terminal physical layer system of a long-term evolution system. The device comprises an interrupt configuring module for configuring interrupt events in an interrupt event list and a time control module, wherein the time control module comprises an interrupt list unit for generating the interrupt event list and combining interrupt events within the same symbol of the interrupt event list and an interrupt generating unit for generating symbol-level interrupt signals according to the configured information and the aligned local mobile radio time reference (MRTR) and providing network time for the interrupt events. The technical scheme provided by the invention solves the problems in the prior art that the interrupt event processing efficiency and the interrupt granularity are relatively low, thereby improving the interrupt event processing efficiency and the interrupt event timing precision.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a timing processing device and method. Background technique [0002] LTE (Long Term Evolution) system is a new generation of wireless communication system based on OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple-Input Multiple-Out-put) technologies , and the LTE terminal chip is a very important part of the development of the LTE industry chain. [0003] In the LTE UE (User Equipment, user equipment, that is, the terminal) physical layer (Physical Layer) system, when the UE camps on a certain cell, the UE needs to generate a time reference synchronized with the camped cell to accurately control the uplink The transmission of the link and the reception of the downlink facilitate the control of various timing relationships specified in the protocol, such as RACH (Random Access Channel, random access channel) access slot, SIB (System Information Block, system...
