Title:
METHOD AND DEVICE FOR FAST RECEIVING AND TRANSMITTING UL DATA AND DL DATA
Document Type and Number:
WIPO Patent Application WO/2015/105378
Kind Code:
A1
Abstract:
A method for fast receiving and transmitting Downlink (DL) and Uplink (UL) data includes: processing, by a User Equipment (UE), DL synchronization according to a Discovery Signal (DiS), or according to the DiS and a Cell-specific Reference Signal (CRS) after a cell X is opened; measuring, by the UE, Reference Signal Receiving Power (RSRP)/Reference Signal Receiving Quality (RSRQ) and/or Channel State Information (CSI) information of the cell X based on the DiS and reporting the RSRP/RSRQ and/or CSI information to a serving cell, which is currently working; receiving, by the UE, a Physical Downlink Control Channel (PDCCH) and Physical Downlink Shared Channel (PDSCH) on the cell X, detecting trigger information of a random access process on the cell X, executing the random access process, measuring and reporting, by the UE, the CSI information to the cell X. With the method and terminal device in the present disclosure, a UL synchronization process of the UE and a process for the UE to measure and feed back the CSI may be speeded up, the transition from the opening of the cell to a moment that the UL and DL data of the UE may be actually received and transmitted may be reduced, the ON/OFF operation of the cell may be effectively supported and the performance of the system may be enhanced.
