Apparatus and method for radio resource management for high reliability and low latency traffic

A network entity for managing wireless transmissions from multiple transmitters, the network entity comprising:

• at least one processor coupled to a memory;
• and
• a non-transitory computer readable storage medium storing programming for execution by the at least one processor, the programming including instructions to:
• send a first grant to a first device associated with a first service, the first grant assigning a first resource for data transmissions associated with the first service and a second resource for data retransmissions associated with the first service, the first resource being a contention-based resource;
• send a second grant to a second device associated with a second service, the second grant assigning the first resource for data transmissions associated with the second service and a third resource for data retransmissions associated with the second service;
• and
• send a third grant to a third device associated with a third service, the third grant assigning the first resource for data transmissions associated with the third service without assigning any resources for data retransmissions associated with the third service, wherein the first service and the second service have higher transmission reliability requirements than the third service.
