Abstract
Various embodiments herein relate to techniques that may improve coverage for a physical random access channel (PRACH). Additionally, some embodiments may relate to techniques for repetition of a channel state information (CSI) report on a physical uplink shared channel (PUSCH) for coverage enhancement. Other embodiments may be described and/or claimed.
Claims20
One or more non-transitory computer-readable media (NTCRM) comprising instructions that, upon execution of the instructions by one or more processors of a user equipment (UE), are to cause the UE to:
- transmit a plurality of physical random access channel (PRACH) transmissions from the UE to a base station;
- identify a last PRACH transmission of the plurality of PRACH transmissions;
- identify, based on the last PRACH transmission, a first symbol of a random access response (RAR) window;
- and
- monitor, in the RAR window from the base station, a RAR transmission that is responsive to at least one PRACH transmission of the plurality of PRACH transmissions.
An apparatus for use in a user equipment (UE), wherein the apparatus comprises:
- memory to store an indication of a plurality of physical random access channel (PRACH) transmissions from the UE to a base station;
- and
- one or more processors configured to:
- identify a last PRACH transmission of the plurality of PRACH transmissions;
- identify, based on the last PRACH transmission, a first symbol of a random access response (RAR) window;
- and
- monitor, in the RAR window from the base station, for a RAR transmission that is responsive to at least one PRACH transmission of the plurality of PRACH transmissions.
One or more non-transitory computer-readable media (NTCRM) comprising instructions that, upon execution of the instructions by one or more processors of a cellular base station, are to cause the base station to:
- identify a plurality of physical random access channel (PRACH) transmissions from a user equipment (UE) to the base station;
- identify a last PRACH transmission of the plurality of PRACH transmissions;
- identify, based on the last PRACH transmission, a first symbol of a random access response (RAR) window;
- and
- transmit, in the RAR window responsive to at least one PRACH transmission of the plurality of PRACH transmissions, a RAR transmission to the UE.
