Abstract
Aspects of the present disclosure provide various devices, methods, and systems for dynamic spectrum sharing of a spectrum between different radio access technologies and multiple frequency division duplexing modes. Dynamic spectrum sharing (DSS) is a technology that allows wireless network operators to share a spectrum between different radio access technologies (RATs). DSS allows an operator to dynamically allocate some existing 4G spectrum to 5G use to deliver 5G services using a shared spectrum.
Claims28
A method for spectrum sharing in wireless communication at a first scheduling entity, the method comprising:
- exchanging scheduling information with a second scheduling entity, the scheduling information identifying a resource usage of a first radio access technology (RAT) in a resource pool for wireless communication, the second scheduling entity associated with the first RAT;
- determining a scheduling constraint imposed by the resource usage of the first RAT for sharing the resource pool for wireless communication using a second RAT, the first scheduling entity associated with the second RAT;
- allocating, based on the scheduling constraint, a resource of the resource pool for wireless communication using the second RAT, the resource comprising a plurality of time-frequency-space resources that are grouped in one or more mini-slots based on a numerology of the second RAT, each mini-slot spanning a time interval corresponding to one or more time domain symbols based on a numerology of the first RAT or the second RAT;
- and
- communicating with a user equipment (UE) using the resource allocated to the second RAT.
A first scheduling entity for wireless communication, comprising:
- a communication interface configured for wireless communication using spectrum sharing between a first radio access technology (RAT) and a second RAT;
- a memory;
- and
- a processor coupled with the communication interface and the memory,
- the processor and the memory being configured to:
- exchange scheduling information with a second scheduling entity, the scheduling information identifying a resource usage of the first RAT in a resource pool for wireless communication, the second scheduling entity associated with the first RAT;
- determine a scheduling constraint imposed by the resource usage of the first RAT for sharing the resource pool for wireless communication using the second RAT, the first scheduling entity associated with the second RAT;
- allocate, based on the scheduling constraint, a resource of the resource pool for wireless communication using the second RAT, the resource comprising a plurality of time-frequency-space resources that are grouped in one or more mini-slots based on a numerology of the second RAT, each mini-slot spanning a time interval corresponding to one or more time domain symbols based on a numerology of the first RAT or the second RAT;
- and
- communicate with a user equipment (UE) using the resource allocated to the second RAT.
A first scheduling entity for wireless communication using spectrum sharing, comprising:
- means for exchanging scheduling information with a second scheduling entity, the scheduling information identifying a resource usage of a first radio access technology (RAT) in a resource pool for wireless communication, the second scheduling entity associated with the first RAT;
- means for determining a scheduling constraint imposed by the resource usage of the first RAT for sharing the resource pool for wireless communication using a second RAT, the first scheduling entity associated with the second RAT;
- means for allocating, based on the scheduling constraint, a resource of the resource pool for wireless communication using the second RAT, the resource comprising a plurality of time-frequency-space resources that are grouped in one or more mini-slots based on a numerology of the second RAT, each mini-slot spanning a time interval corresponding to one or more time domain symbols based on a numerology of the first RAT or the second RAT;
- and
- means for communicating with a user equipment (UE) using the resource allocated to the second RAT.
A non-transitory computer-readable medium storing computer-executable code at a first scheduling entity for wireless communication using dynamic spectrum sharing, comprising code for causing a processor to:
- exchange scheduling information with a second scheduling entity, the scheduling information identifying a resource usage of a first radio access technology (RAT) in a resource pool for wireless communication, the second scheduling entity associated with the first RAT;
- determine a scheduling constraint imposed by the resource usage of the first RAT for sharing the resource pool for wireless communication using a second RAT, the first scheduling entity associated with the second RAT;
- allocate, based on the scheduling constraint, a resource of the resource pool for wireless communication using the second RAT, the resource comprising a plurality of time-frequency-space resources that are grouped in one or more mini-slots based on a numerology of the second RAT, each mini-slot spanning a time interval corresponding to one or more time domain symbols based on a numerology of the first RAT or the second RAT;
- and
- communicate with a user equipment (UE) using the resource allocated to the second RAT.
