Abstract
The method for air interface resource allocation, including allocating a first air interface resource to a first service with a first latency sensitivity, allocating, to a second service with a second latency sensitivity that is greater than the first latency sensitivity, a second air interface resource on subcarriers of all frequency bands within a current transmission time interval (TTI); and preempting, for the second service, the first air interface resource allocated to the first service, wherein the second service has a higher priority for obtaining the first air interface resource than the first service.
Claims20
An air interface resource allocation method, comprising:
- allocating a first air interface resource to a first service with a first latency sensitivity;
- allocating, to a second service with a second latency sensitivity that is greater than the first latency sensitivity, a second air interface resource on subcarriers of all frequency bands within a current transmission time interval (TTI);
- and
- preempting, for the second service, the first air interface resource allocated to the first service, wherein the second service has a higher priority for obtaining the first air interface resource than the first service.
A network device, comprising:
- a transmitter;
- a processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
- allocate a first air interface resource to a first service with a first latency sensitivity;
- allocate, to a second service with a second latency sensitivity that is greater than the first latency sensitivity, a second air interface resource on subcarriers of all frequency bands within a current transmission time interval (TTI);
- preempt, for the second service, the first air interface resource allocated to the first service, wherein the second service has a higher priority for obtaining the first air interface resource than the first service;
- and
- cause the transmitter to send, based on the allocated first air interface resource, at least one of data or control information to at least one of a terminal corresponding to the second service or a terminal corresponding to the first service.
The network device according to claim it, wherein the instructions to preempt, for the second service, the first air interface resource comprise instructions to:
- preempt, for the second service, in a time domain, the first air interface resource already allocated to the first service.
A network device, comprising:
- a transmitter;
- a processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
- allocate, to a second service with a second latency sensitivity, a second air interface resource on subcarriers of all frequency bands within a current transmission time interval (TTI);
- preempt, for the second service, a first air interface resource allocated to a first service with a first latency sensitivity that is less than the second latency sensitivity and with a lower priority for obtaining the first air interface resource than a priority of the second service;
- and
- cause the transmitter to send, using allocated first air interface resource, at least one of data or control information to a terminal corresponding to the second service.
