Patent ID: 10111066

Abstract:
Methods to support measurements for LTE user equipments are proposed. Due to reduced bandwidth design for cost reduction, resources for UEs are limited to contiguous six physical resource block (PRB) pairs (1.4 MHz). Six or less contiguous PRBs per narrow sub-band located in the whole channel bandwidth is allocated for transmission and reception for UEs. Novel control channel and data channel designs are proposed to make UEs be able to camp on LTE cells. Methods for intra-frequency measurement, for received signal time difference (RSTD) measurement, and for channel quality assessment for UEs are also provided. In one embodiment, UE is allocated with a measurement gap for intra-frequency measurements and RSTD measurements. In another embodiment, UE is configured with a frequency-hopping pattern and receives a PRB pair starting index per subframe for CSI measurement.
