Abstract
Embodiments described herein relate to methods and apparatuses for a New Radio base station that is spectrum sharing with a Long Term Evolution base station. A method in a first scheduler for use in a New Radio base station includes determining that one or more NR messages are to be scheduled for transmission during a time period, wherein the one or more NR messages cannot perform LTE Cell Specific Reference Signal, CRS, rate matching; and responsive to the determination, transmitting a first indication that there are one or more NR messages that cannot perform LTE CRS rate matching to be transmitted during the time period to a shared resource allocator configured to allocate resources to the NR base station and the LTE base station.
Claims24
A method in first scheduler for use in a New Radio base station that is spectrum sharing with a Long Term Evolution, LTE, base station, the method comprising:
- determining that one or more NR messages are to be scheduled for transmission during a time period, the one or more NR messages cannot perform LTE Cell Specific Reference Signal, CRS, rate matching;
- and
- responsive to the determination, transmitting a first indication that there are one or more NR messages that cannot perform LTE CRS rate matching to be transmitted during the time period to a shared resource allocator configured to allocate resources to the NR base station and the LTE base station.
A method in a second scheduler for use in a Long Term Evolution base station that is spectrum sharing with a New Radio, NR, base station, the method comprising:
- receiving a first indication that there are one or more NR messages to be transmitted by the NR base station during a time period that cannot perform LTE Cell Specific Reference Signal, CRS, rate matching;
- and
- responsive to receiving the indication, instructing a DL transmitter in the LTE base station to mute CRS on one or more resources during the time period.
(canceled)
The method as claimed in claim 72 further comprising:
- wherein the one or more resources comprise one or more resources allocated to the one or more messages, and wherein the method further comprises:
- receiving a second indication of the one or more resources.
(canceled)
A method in a shared resource allocator configured to allocate shared resources to a Long Term Evolution base station and a New Radio, NR, base station that are spectrum sharing, the method comprising:
- receiving a first indication, from the NR base station, that one or more NR messages to be scheduled for transmission during a time period cannot perform LTE CRS rate matching;
- and
- responsive to receiving the first indication from the NR base station, transmitting a second indication, to the LTE base station, that there are one or more NR messages to be scheduled for transmission during the time period that cannot perform LTE CRS rate matching.
The method as claimed in claim 132 wherein the time period comprises a transmission time interval.
A first scheduler for use in a New Radio base station that is spectrum sharing with a Long Term Evolution, LTE, base station, the first scheduler comprising processing circuitry configured to:
- determine that one or more NR messages are to be scheduled for transmission during a time period, the one or more NR messages cannot perform LTE Cell Specific Reference Signal, CRS, rate matching;
- and
- responsive to the determination, transmit a first indication that there are one or more NR messages that cannot perform LTE CRS rate matching to be transmitted during the time period to a shared resource allocator configured to allocate resources to the NR base station and the LTE base station.
A second scheduler for use in a Long Term Evolution base station that is spectrum sharing with a New Radio, NR, base station, the second scheduler comprising processing circuitry configured to:
- receive a first indication that there are one or more NR messages to be transmitted by the NR base station during a time period that cannot perform LTE Cell Specific Reference Signal, CRS, rate matching;
- and
- responsive to receiving the indication, instruct a DL transmitter in the LTE base station to mute CRS on one or more resources during the time period.
(canceled)
A shared resource allocator configured to allocate shared resources to a Long Term Evolution base station and a New Radio, NR, base station that are spectrum sharing, the shared resource allocator comprising processing circuitry configured to:
- receive a first indication, from the NR base station, that one or more NR messages to be scheduled for transmission during a time period cannot perform LTE CRS rate matching;
- and
- responsive to receiving the first indication from the NR base station, transmit a second indication, to the LTE base station, that there are one or more NR messages to be scheduled for transmission during the time period that cannot perform LTE CRS rate matching.
