Abstract

Apparatuses, systems, and techniques to detect whether fifth-generation new radio (5G-NR) devices are transmitting data. In at least one embodiment, a receiver detects whether 5G-NR devices are transmitting 5G-NR signals based on a number of 5G-NR devices sharing a same time and frequency.

Claims (23)

1 . A system, comprising: one or more processors to:

determine a threshold based, at least in part, on information from a plurality of devices multiplexed on a same time and frequency allocation and one or more scaling factors, the one or more scaling factors based on a number of antennas at one or more base stations; and

detect whether one or more devices of the plurality of devices are transmitting data on one or more fifth-generation new radio (5G-NR) signals, based, at least in part, on a symbol energy being less than the threshold.

2 . The system of claim 1 , wherein the data is transmitted via a physical uplink control channel.

3 . The system of claim 1 , wherein the one or more devices share a physical resource block corresponding to the same time and frequency.

4 . The system of claim 1 , wherein detection of the one or more devices not transmitting the data is based, at least in part, on an algorithm, wherein input to the algorithm includes a strength of a received 5G-NR signal and the number of devices sharing the same time and frequency.

5 . The system of claim 1 , wherein the one or more processors determine the threshold value which is indicative of whether a device is transmitting based, at least in part, on the number of receiver antennas at a base station.

6 . The system of claim 1 , wherein detection of whether the one or more devices are transmitting data is based, at least in part, on a total symbol energy of a data transmission of the one or more devices being greater than a threshold value.

7 . One or more processors, comprising: circuitry to:

determine a threshold based, at least in part, on information from a plurality of devices multiplexed on a same time and frequency allocation and one or more scaling factors, the one or more scaling factors based on a number of antennas at one or more base stations; and

detect whether one or more devices of the plurality of devices are transmitting data on one or more fifth-generation new radio (5G-NR) signals, based, at least in part, on a symbol energy being less than the threshold.

8 . The one or more processors of claim 7 , wherein the data is transmitted via a physical uplink control channel.

9 . The one or more processors of claim 7 , wherein the one or more devices share a physical resource block corresponding to the same time and frequency.

10 . The one or more processors of claim 7 , wherein the circuitry is to determine the threshold value which is indicative of whether a device is transmitting based, at least in part, on the number of receiver antennas at a base station.

11 . The one or more processors of claim 7 , wherein detection of whether the one or more devices are transmitting data is based, at least in part, on a total symbol energy of a data transmission of the one or more devices being greater than a threshold value.

12 . A method, comprising:

determining a threshold based, at least in part, on information from a plurality of devices multiplexed on a same time and frequency allocation and one or more scaling factors, the one or more scaling factors based on a number of antennas at one or more base stations; and

detecting whether one or more devices of the plurality of devices are transmitting data on one or more fifth-generation new radio (5G-NR) signals, based, at least in part, on a symbol energy being less than the threshold.

13 . The method of claim 12 , wherein the data is transmitted via a physical uplink control channel.

14 . The method of claim 12 , wherein the devices share a physical resource block corresponding to the unit of time and frequency.

15 . The method of claim 12 , further comprising: determining the threshold value which is indicative of whether a device is transmitting based, at least in part, on the number of receiver antennas at a base station.

16 . The method of claim 12 , wherein detection of whether the one or more devices are transmitting data is based, at least in part, on a total symbol energy of a data transmission of the one or more devices being greater than a threshold value.

17 . The method of claim 12 , wherein detection of the one or more devices not transmitting the data is based, at least in part, on a strength of a received 5G-NR signal and the number of devices sharing the same time and frequency.
