Abstract

A method, system and non-transitory computer-readable medium are provided. The method includes determining that a user equipment (UE) is camped on a new radio (NR) cell and to a long term evolution (LTE) cell, determining a reference signal received power (RSRP) of the LTE cell, determining an RSRP of the NR cell, and assigning an uplink data flow configuration for the UE based on the RSRP of the LTE cell and the RSRP of the NR cell.

Claims (40)

1 . A method, comprising:

determining that a user equipment (UE) is camped on a new radio (NR) cell and to a long term evolution (LTE) cell;

determining a reference signal received power (RSRP) of the LTE cell;

determining an RSRP of the NR cell;

assigning an uplink data flow configuration for the UE based on threshold determinations with respect to the RSRP of the LTE cell and the RSRP of the NR cell,

wherein the threshold determinations are based on at least one RSRP threshold value of at least one of the LTE cell and the NR cell, and

wherein the method further comprises adjusting dynamically the at least one RSRP threshold value in response to an obtained block error rate (BLER) value being not equal to an error threshold percentage.

2 . The method of claim 1 , wherein the uplink data flow configuration for the UE causes the UE to be allowed to transmit uplink data on the NR cell when the RSRP of the NR cell is greater than or equal to an NR RSRP threshold.

3 . The method of claim 2 , further comprising adjusting the NR RSRP threshold based on a block error rate (BLER) of the NR cell.

4 . The method of claim 1 , wherein the uplink data flow configuration for the UE causes the UE to be blocked from transmitting uplink data on the NR cell when the RSRP of the NR cell is less than an NR RSRP threshold.

5 . The method of claim 1 , wherein the uplink data flow configuration for the UE causes the UE to be allowed to transmit uplink data on the LTE cell when the RSRP of the LTE cell is greater than or equal to an LTE RSRP threshold.

6 . The method of claim 5 , further comprising adjusting the LTE RSRP threshold based on a block error rate (BLER) of the LTE cell.

7 . The method of claim 1 , wherein the uplink data flow configuration for the UE causes the UE to be blocked from transmitting uplink data on the LTE cell when the RSRP of the LTE cell is less than an LTE RSRP threshold.

8 . A system, comprising:

a memory configured to store instructions; and

one or more processors configured to execute the instructions to:

determine that a user equipment (UE) is camped on a new radio (NR) cell and to a long term evolution (LTE) cell;

determine a reference signal received power (RSRP) of the LTE cell;

determine an RSRP of the NR cell;

assign an uplink data flow configuration for the UE based on threshold determinations with respect to the RSRP of the LTE cell and the RSRP of the NR cell,

wherein the threshold determinations are based on at least one RSRP threshold value of at least one of the LTE cell and the NR cell, and

wherein the one or more processors are further configured to adjust dynamically the at least one RSRP threshold value in response to an obtained block error rate (BLER) value being not equal to an error threshold percentage.

9 . The system of claim 8 , wherein the uplink data flow configuration for the UE causes the UE to be allowed to transmit uplink data on the NR cell when the RSRP of the NR cell is greater than or equal to an NR RSRP threshold.

10 . The system of claim 9 , wherein the one or more processors are further configured to execute the instructions to adjust the NR RSRP threshold based on a block error rate (BLER) of the NR cell.

11 . The system of claim 8 , wherein the uplink data flow configuration for the UE causes the UE to be blocked from transmitting uplink data on the NR cell when the RSRP of the NR cell is less than an NR RSRP threshold.

12 . The system of claim 8 , wherein the uplink data flow configuration for the UE causes the UE to be allowed to transmit uplink data on the LTE cell when the RSRP of the LTE cell is greater than or equal to an LTE RSRP threshold.

13 . The system of claim 12 , wherein the one or more processors are further configured to execute the instructions to adjust the LTE RSRP threshold based on a block error rate (BLER) of the LTE cell.

14 . The system of claim 8 , wherein the uplink data flow configuration for the UE causes the UE to be blocked from transmitting uplink data on the LTE cell when the RSRP of the LTE cell is less than an LTE RSRP threshold.

15 . A non-transitory computer-readable medium storing instructions, the instructions comprising: one or more instructions that, when executed by one or more processors of a wireless communication system, cause the one or more processors to:

determine that a user equipment (UE) is camped on a new radio (NR) cell and to a long term evolution (LTE) cell;

determine a reference signal received power (RSRP) of the LTE cell;

determine an RSRP of the NR cell;

assign an uplink data flow configuration for the UE based on threshold determinations with respect to the RSRP of the LTE cell and the RSRP of the NR cell,

wherein the threshold determinations are based on at least one RSRP threshold value of the LTE cell and the NR cell, and

wherein the method further comprises adjusting dynamically the at least one RSRP threshold value in response to an obtained block error rate (BLER) value being not equal to an error threshold percentage.

16 . The non-transitory computer-readable medium of claim 15 , wherein the uplink data flow configuration for the UE causes the UE to be allowed to transmit uplink data on the NR cell when the RSRP of the NR cell is greater than or equal to an NR RSRP threshold.

17 . The non-transitory computer-readable medium of claim 16 , wherein the instructions, when executed, further cause the one or more processors to adjust the NR RSRP threshold based on a block error rate (BLER) of the NR cell.

18 . The non-transitory computer-readable medium of claim 15 , wherein the uplink data flow configuration for the UE causes the UE to be blocked from transmitting uplink data on the NR cell when the RSRP of the NR cell is less than an NR RSRP threshold.

19 . The non-transitory computer-readable medium of claim 15 , wherein the uplink data flow configuration for the UE causes the UE to be allowed to transmit uplink data on the LTE cell when the RSRP of the LTE cell is greater than or equal to an LTE RSRP threshold.

20 . The non-transitory computer-readable medium of claim 19 , wherein the instructions, when executed, further cause the one or more processors to adjust the LTE RSRP threshold based on a block error rate (BLER) of the LTE cell.
