Method for UL data transmission in wireless communication system

摘要

The present invention provides a UL data transmission method in a wireless communication system, including determining, by the UE, UL virtual resources allocated to the UE by the eNB according to Downlink Control Information (DCI) used for scheduling UL physical resources sent from the eNB to the UE; determining, by the UE, the UL physical resources used for transmitting the UL data after frequency hopping processing in a preset frequency domain when determining that the UL data needs to be processed with frequency hopping processing according to the DCI, if the UL virtual resources allocated to the UE locate at UL sub-frames in a non-aggregation K of any wireless frame, and locate at the preset frequency domain; bearing, by the UE, the UL data and feeding the UL data back to the eNB utilizing the determined UL physical resources which are processed with the frequency hopping processing and used for transmitting the UL data. With the present invention, the PUSCH channel resource collision may be avoided, the frequency diversity gain may be maximized, and the PUSCH performances may be enhanced.

1. A method for uplink (UL) data transmission in a wireless communication system, the method comprising:
determining, by a User Equipment (UE), UL virtual resources allocated to the UE by an Evolved Node B (eNB) according to Downlink Control Information (DCI) used for scheduling UL physical resources sent from the eNB to the UE, wherein at least two Component Carriers (CC)s having different frame structure configurations are present in CCs configured for the UE; determining, by the UE, the UL physical resources used for transmitting UL data after frequency hopping processing in a preset frequency domain when determining that the UL data is to be processed with frequency hopping processing according to the DCI, if the UL virtual resources allocated to the UE are located at UL sub-frames in a non-aggregation K of any wireless frame and located at the preset frequency domain; transmitting, by the UE, the UL data to the eNB utilizing the determined UL physical resources which are processed with the frequency hopping processing and used for transmitting the UL data; wherein an aggregation K is an aggregation of UL sub-frames which are determined according to configured and different CC frame structure configurations and used for feeding back Acknowledgment/Negative Acknowledgement (ACK/NACK) information, and wherein the preset frequency domain is an overlapping area of a Physical Uplink Control Channel (PUCCH) area of UL sub-frames in the aggregation K and a Physical Uplink Shared Channel (PUSCH) area of sub-frames in the non-aggregation K.
