Abstract
The spectrum sharing dynamic mode switch in TDMA may allow for the transmission of only one radio mode per transmission time interval (TTI). Such system may address radio interference or retransmission (reTX) failures, among other things.
Claims20
A method comprising:
- receiving a first message from a user equipment, wherein the first message comprises:
- an indication of a location of the user equipment, wherein the location is within bounds of a cell area of a first base station, and
- an indication of one or more radio modes of the user equipment, wherein the one or more radio modes of the user equipment is new radio (NR) or long-term evolution (LTE);
- receiving information about a buffer size of a radio of the user equipment;
- determining a transmission time interval (TTI) for the one or more radio modes of the user equipment, wherein the determining the TTI comprises determining a number of time slots assigned to the user equipment for transmitting to the user equipment based on the buffer size of the radio of the user equipment, wherein transmitting to the user equipment comprises transmitting a first number of continuous alternating time slots for an NR mode or transmitting a second number of continuous alternating time slots for an LTE mode, wherein the first number of continuous alternating time slots and the second number of continuous alternating time slots are equal and are selected based on the buffer size of the radio of the user equipment, and wherein transmitting to the user equipment comprises transmitting with no frequency sharing among the NR mode and the LTE mode in frequency domain to reduce interference;
- and
- sending, to the user equipment, a second message, wherein the second message comprises an indication of the TTI for the one or more radio modes.

A system comprising:
- one or more processors;
- and
- memory coupled with the one or more processors, the memory storing executable instructions that when executed by the one or more processors cause the one or more processors to effectuate operations comprising:
- receiving a first message from a user equipment, wherein the first message comprises:
- an indication of a location of the user equipment, wherein the location is within bounds of a cell area of a first base station, and
- an indication of one or more radio modes of the user equipment, wherein the one or more radio modes of the user equipment is new radio (NR) or long-term evolution (LTE);
- receiving information about a buffer size of a radio of the user equipment;
- determining, based on the first message and the information about the buffer size of the radio of the user equipment, a transmission time interval (TTI) for the one or more radio modes of the user equipment, wherein the determining the TTI comprises determining a number of time slots assigned to the user equipment for transmitting to the user equipment based on the buffer size of the radio of the user equipment, wherein transmitting to the user equipment comprises transmitting a first number of continuous alternating time slots for an NR mode or transmitting a second number of continuous alternating time slots for an LTE mode, wherein the first number of continuous alternating time slots and the second number of continuous alternating time slots are equal and are selected based on the buffer size of the radio of the user equipment, and wherein transmitting to the user equipment comprises transmitting with no frequency sharing among the NR mode and the LTE mode in frequency domain to reduce interference;
- and
- sending, to the user equipment, a second message, wherein the second message comprises an indication of the TTI for the one or more radio modes.

A non-transitory computer readable storage medium storing computer executable instructions that when executed by a computing device cause said computing device to effectuate operations comprising:
- receiving a first message from a user equipment, wherein the first message comprises:
- an indication of a location of the user equipment, wherein the location is within bounds of a cell area of a first base station, and
- an indication of one or more radio modes of the user equipment, wherein the one or more radio modes of the user equipment is new radio (NR) or long-term evolution (LTE);
- receiving information about a buffer size of a radio of the user equipment;
- determining, based on the first message and the information about the buffer size of the radio of the user equipment, a transmission time interval (TTI) for the one or more radio modes of the user equipment, wherein the determining the TTI comprises determining a number of time slots assigned to the user equipment for transmitting to the user equipment based on the buffer size of the radio of the user equipment, wherein transmitting to the user equipment comprises transmitting a first number of continuous alternating time slots for an NR mode or transmitting a second number of continuous alternating time slots for an LTE mode, wherein the first number of continuous alternating time slots and the second number of continuous alternating time slots are equal and are selected based on the buffer size of the radio of the user equipment, and wherein transmitting to the user equipment comprises transmitting with no frequency sharing among the NR mode and the LTE mode in frequency domain to reduce interference;
- and
- sending, to the user equipment, a second message, wherein the second message comprises an indication of the TTI for the one or more radio modes.
