Patent ID: 10638503

Abstract:
A method is disclosed of a network node adapted to operate in association with first and second wireless communication devices associated with first and second latency requirements, respectively, wherein a latency of the second latency requirement is lower than a latency of the first latency requirement. The method comprises receiving a first scheduling request for uplink transmission by the first wireless communication device, and transmitting a first scheduling grant indicating an allocated first communication resource for the uplink transmission by the first wireless communication device. The method also comprises receiving (simultaneously with or after transmitting the first scheduling grant) a second scheduling request for uplink transmission by the second wireless communication device, determining whether the first communication resource and an allocated second communication resource for the uplink transmission by the second wireless communication device at least partly overlap, and transmitting a second scheduling grant indicating the second communication resource. The method further comprises (if it is determined that the first and second communication resources at least partly overlap) transmitting (to the first wireless communication device) a scheduling grant annulment instruction for preventing the uplink transmission by the first wireless communication device using the first communication resource. Corresponding method of the first network node is also disclosed, along with corresponding computer program product, arrangements, network node and first wireless communication device.
