Communication resource allocation method, allocation device, base station and terminal

A communication resource allocation method, comprising:

• receiving a first signaling and a second signaling transmitted by a base station;
• acquiring, according to the first signaling, granularity information of time-frequency resource and a frequency domain resource range determined by the base station according to the service type of the current service, and acquiring, according to the second signaling, frequency domain resource selected and allocated by the base station in the frequency domain resource range;
• determining resource block information allocated by the base station and used for processing the current service, according to the granularity information of the time-frequency and the frequency domain resource;
• and
• processing the current service based on the resource block information.

A base station, comprising:

• a processor;
• and
• a memory storing a plurality of instructions, which when executed by the processor, causes the processor to:
• determine a service type of a current service when a service bearer is established;
• determine granularity information of time-frequency resource and a frequency domain resource range corresponding to the service type according to the service type of the current service;
• and
• transmit the granularity information of the time-frequency resource and the frequency domain resource range corresponding to the service type to a terminal that requests to establish the service bearer.
