Title:
SYSTEM AND METHOD FOR IMPROVING SPECTRAL EFFICIENCY AND COVERAGE FOR USER EQUIPMENTS
Document Type and Number:
WIPO Patent Application WO/2016/053026
Kind Code:
A1
Abstract:
Methods and apparatus are provided to improve spectral efficiency, coverage, and data rates for communication between a base station and user equipments (UEs). In a first case, mechanisms to reduce a size of a random access response message are provided. In a second case, mechanisms to support UE-group scheduling are provided. In a third case, control signaling designs according to a coverage requirement for a UE are provided. In a fourth case, designs for allocation of downlink (DL) subframes and uplink (UL) subframes in order to adjust a data rate and minimize switching between DL and UL for a half-duplex FDD UE are provided.
