Time-division multiplexing for cellular dual connectivity

A cellular communication system, comprising:

• a Long-Term Evolution (LTE) base station that receives LTE scheduling requests from a cellular communication device, wherein the LTE scheduling requests are for an LTE uplink;
• a New Radio (NR) base station that receives NR scheduling requests from the cellular communication device, wherein the NR scheduling requests are for an NR uplink;
• and
• scheduling logic configured to determine that concurrent transmission by the cellular communication device of an LTE uplink signal and an NR uplink signal will cause a transmit power of the cellular communication device to exceed a power threshold and in response to (a) grant the LTE scheduling requests to allow LTE uplink transmissions to occur during respective first time intervals, and (b) grant the NR scheduling requests to allow NR uplink transmissions to occur during respective second time intervals, wherein the second time intervals are interleaved with the first time intervals.

A system, comprising:

• one or more processors;
• one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform actions comprising:
• receiving information that identifies timing of Long-Term Evolution (LTE) uplink transmissions by a cellular communication device;
• receiving, from the cellular communication device, New Radio (NR) scheduling requests for an NR uplink;
• determining that concurrent LTE and NR uplink transmissions by the cellular communication device will cause the cellular communication device to exceed a power threshold;
• and
• in response to determining that the concurrent LTE and NR uplink transmissions will cause the cellular communication device to exceed the power threshold, granting the NR scheduling requests to allow NR uplink transmissions of the cellular communication device to be multiplexed among the LTE uplink transmissions of the cellular communication device.
