METHOD AND APPARATUS FOR REDUCING LATENCY OF LTE UPLINK TRANSMISSIONS

摘要

A method and apparatus reduce latency of Long Term Evolution (LTE) uplink transmissions. An indication can be acquired, where the indication can indicate a set of frequency domain resource blocks for possible Physical Uplink Shared Channel (PUSCH) transmission in an uplink subframe. A subset of resource blocks can be selected from the set of frequency domain resource blocks for possible PUSCH transmission based on a selection criterion. The selection criterion can use at least a resource set size acquired from the indication, can use a modulo function, and can use an identifier associated with the User Equipment (UE). The PUSCH can be transmitted in the selected subset of resource blocks in the uplink subframe.

1. A method in a user equipment, the method comprising:
acquiring an indication that indicates a set of frequency domain resource blocks for possible physical uplink shared channel transmission in an uplink subframe; selecting a subset of resource blocks from the set of frequency domain resource blocks for possible physical uplink shared channel transmission based on a selection criterion, wherein the selection criterion uses at least a resource set size acquired from the indication, a modulo function, and an identifier associated with the user equipment; and transmitting a physical uplink shared channel in the selected subset of resource blocks in the uplink subframe.
