Enhancing detection in wireless communication systems
Methods, systems, and computer program products are provided for enhancing detection in wireless communication systems. In some implementations, a signal received by one or more antennas on a communication channel can be processed. The signal can include a frame having a plurality of symbols, and the plurality of symbols can include one or more symbol groups. A signal to interference noise power ratio (SINR) associated with the received signal can be determined using a signal power determined based on subcarrier resource allocation and noise power determined based on one or more reserved subcarrier allocation associated with the received signal.
1. A computer-implemented method, comprising:
processing, using at least one processor, a signal received by one or more antennas, the signal including a frame having a plurality of symbols, on a communication channel, the plurality of symbols including one or more symbol groups; and
determining, using the at least one processor, a signal to interference noise power ratio associated with the received signal using a signal power determined based on subcarrier resource allocation and noise power determined based on one or more reserved subcarrier allocation associated with the received signal.
2. The method according to claim 1 , wherein determining of the signal power is based on a correlation of subcarrier resource allocations associated with one or more adjacent symbol groups and one or more non-adjacent symbol groups in the one or more symbol groups.
3. The method according to claim 1 , wherein the noise power is determined based on the one or more reserved subcarrier allocation associated with a narrowband internet of things (NB-IoT) region of the received signal.
4. The method according to claim 1 , wherein the noise power is determined based on the one or more reserved subcarrier allocation being adjacent to a narrowband internet of things (NB-IoT) region of the received signal.
5. The method according to claim 1 , wherein the determining is based on at least one of a carrier frequency offset and a timing advance offset associated with the received signal.
6. The method according to claim 1 , wherein the signal includes one or more narrowband internet of things (NB-IoT) physical random access channel (NPRACH) signals.
7. The method according to claim 6 , further comprising repeating the determining of the signal to interference noise power ratio in accordance with the received one or more NPRACH signals.
8. The method according to claim 7 , further comprising detecting one or more preambles associated with the received signal in accordance with the repeating.
9. The method according to claim 8 , wherein the one or more preambles are detected in accordance with one or more hopping sequences associated with the one or more symbol groups.
10. The method according to claim 8 , wherein the detecting is based on a comparison of the determined signal to interference noise power ratio to one or more signal to interference noise power ratio thresholds.
11. The method according to claim 1 , wherein the signal does not include any narrowband internet of things (NB-IoT) physical random access channel (NPRACH) signals.
12. The method according to claim 11 , further comprising repeating the determining of the signal to interference noise power ratio in accordance with the received signal without any NPRACH signals.
13. The method according to claim 12 , wherein no preambles associated with the received signal are detected based on the repeating.
14. The method according to claim 1 , wherein the signal is received from at least one of the following: a user equipment, a base station, and any combination thereof.
15. The method according to claim 1 , wherein at least one of the processing, and the determining is performed by a base station having at least one processor communicatively coupled to at least one memory, the base station further including a radio transmitter and a radio receiver.
16. The method according to claim 15 , wherein the base station includes at least one of the following: an eNodeB base station, a gNodeB base station, and any combination thereof.
17. The method according to claim 16 , wherein the communication channel includes an uplink communication channel.
18. The method according to claim 17 , wherein the uplink communication channel is established with the base station.
19. An apparatus, comprising:
at least one processor; and
at least one non-transitory storage media storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
processing a signal received by one or more antennas, the signal including a frame having a plurality of symbols, on a communication channel, the plurality of symbols including one or more symbol groups; and
determining a signal to interference noise power ratio associated with the received signal using a signal power determined based on subcarrier resource allocation and noise power determined based on one or more reserved subcarrier allocation associated with the received signal.
20. At least one non-transitory storage media storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:
