US 12,193,044 B2 · Resource selection for 5G NR V2X communications

Abstract

One example embodiment provides one or more of: measuring, via a user equipment (UE), sidelink received signal strength indicator (SL-RSSI) values and sidelink reference signal power received (SL-RSRP) values from a current window of a communication channel shared among a plurality of UEs, measuring, via the UE, the SL-RSRP values from a frequency-domain and a time-domain of a current window of a communication channel shared among the plurality of UEs, excluding a first subset of communication resources from a next window of the communication channel based on the RSSI values in the current window, excluding a first subset of communication resources from a next window of the communication channel based on the SL-RSRP values from a time-domain, excluding a second subset of communication resources from the next window of the communication channel based on the RSRP values, excluding a second subset of communication resources from the next window of the communication channel based on the SL-RSRP values from a frequency-domain, and selecting and reserving resource(s) remaining in the next window of the communication channel after exclusion of the first and second subsets of communication resources from the next window.

A method comprising:

measuring, via a user equipment (UE), sidelink reference received signal power (SL-RSRP) values from a frequency domain and a time domain of a current window of a communication channel shared among a plurality of UEs;
excluding time slots from a next window of the communication channel based on the SL-RSRP values from the time domain;
excluding sub-channels corresponding to remaining non-excluded time slots a from the next window of the communication channel based on the SL-RSRP values from the frequency domain;
and
selecting and reserving a resource remaining in the next window of the communication channel after the excluding the time slots and the sub-channels.

3 more elements

A non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to perform:

measuring, via a user equipment (UE), sidelink reference received signal power (SL-RSRP) values from a frequency domain and a time domain of a current window of a communication channel shared among a plurality of UEs;
excluding time slots from a next window of the communication channel based on the SL-RSRP values from the time domain;
excluding sub-channels corresponding to remaining non-excluded time slots from the next window of the communication channel based on the SL-RSRP values from the frequency domain;
and
selecting and reserving a resource remaining in the next window of the communication channel after the excluding the time slots and the sub-channels.
