Abstract

The invention relates to a method, device and terminal for coordinating LTE (Long Term Evolution) system random access and pilot frequency measurement conflict. The method comprises the following steps: a physical layer MC (Main Control) software module receives and forwards a random access request transmitted by a high layer to a UL-RAPC (Uplink-Random Access Control) module and receives and forwards a pilot frequency measurement request transmitted by the high layer to a CSR-GAPC (Cell Search Pilot Frequency) measuring module; and the UL-RAPC and the CSR-GAPC respectively control an RF (Radio Frequency) module to work respectively according to the random access request and the pilot frequency measurement request by combining with a pilot frequency measurement identification at the reference time provided by a TPU (Time Control Module). The invention realizes the aim that corresponding tasks are carried out according to a certain sequence and priority on the premise of not completely suspending any work, effectively solves the problem of conflict between random access and pilot frequency measurement; and has the advantages of simple device maintenance and clear method flow.

Description

technical field [0001] The present invention relates to the field of wireless communication technologies, and in particular to a method, device and terminal for coordinating random access and inter-frequency measurement conflicts of an LTE (Long Term Evolution, Long Term Evolution) system. Background technique [0002] The LTE system is a new generation wireless communication system based on OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple-Input Multiple-Out-put) technologies. In the physical layer of the LTE system, random access is used to achieve uplink synchronization between the UE (terminal) and the network side, and to obtain UE identification; inter-frequency measurement is used to measure the channel quality of inter-frequency cells when the channel quality is not ideal , which are widely used in multimode systems. [0003] Both random access and inter-frequency measurement are very important physical layer processes, however, in some occasions,...
