Method for configuring physical channel, base station and user equipment
The present disclosure provides a method performed by a User Equipment (UE). The method comprises: monitoring a physical channel that is transmitted repetitively at a repetition level; and receiving configuration information for reconfiguring the repetition level. The initial repetition level is determined during a random access procedure. The present disclosure also provides a method performed by a base station, as well as a base station and a UE. With the present disclosure, it is possible to improve resource utilization and spectrum/energy efficiency of MTC UEs supported by the LTE and reduce inter-cell time/frequency resource collisions.
1. A User Equipment (UE), comprising:
a processor, and
non-transitory memory in electronic communication with the processor, wherein instructions stored in the memory are executable by the processor to:
determine a repetition level of a Physical Downlink Control Channel (PDCCH) for Random Access Response (RAR) based on a coverage enhancement level for a Physical Random Access Channel (PRACH),
determine a starting subframe for the PDCCH based on the coverage enhancement level, and
monitor the PDCCH based on the repetition level and the starting subframe,
wherein the repetition level is determined initially during a random access procedure.
2. A Base Station (BS) apparatus, comprising:
a processor, and
non-transitory memory in electronic communication with the processor, wherein instructions stored in the memory are executable by the processor to:
determine a repetition level of a Physical Downlink Control Channel (PDCCH) for Random Access Response (RAR) based on a coverage enhancement level for a Physical Random Access Channel (PRACH),
determine a starting subframe for the PDCCH based on the coverage enhancement level, and
transmit the PDCCH based on the repetition level and the starting subframe,
wherein the repetition level is determined initially during a random access procedure.
