Abstract
Wireless communication methods and devices are provided. The wireless communication method includes transmitting a reference signal and a data signal in a Physical Resource Block (PRB) with a coverage enhancement level, wherein the number of resource elements transmitting the reference signal in the PRB is determined by the coverage enhancement level, the channel type and/or the coding rate of the data signal.
Claims16
A wireless communication method comprising:
- receiving a reference signal and a data signal in a Physical Resource Block (PRB), based on a coverage enhancement level represented by a number of transmission repetitions;
- and
- processing the received reference signal and the received data signal,
- wherein a number of the resource elements used to transmit the reference signal in the PRB is determined by one or more of the coverage enhancement level, a channel type, and a coding rate of the data signal, and
- the data signal is used to transmit a Physical Downlink Control Channel (PDCCH) or an Enhanced PDCCH (EPDCCH), usage of the resource elements used to transmit the reference signal in the PRB is indicated by a System Information Block (SIB) or is specified, and the reference signal is a Cell-specific Reference Signal (CRS) or a Demodulation Reference Signal (DMRS).
