摘要

A method of operating a communication device to transmit data to a wireless communication network includes a grant free of a physical uplink shared channel of a wireless access interface provided by a wireless communication network to form one or more transport blocks of uplink data for transmission. processing uplink data for transmission on the resources. The grant free resources provide communication resources of a physical shared uplink channel in each of a plurality of time-divided units of a wireless access interface for transmitting uplink data. The method includes selecting one of a plurality of configurations for transmitting uplink data on the grant free resources, and transmitting the uplink data on the grant free resources according to the selected configuration. Each of the plurality of configurations includes one of grant-free resources, a transmission period during which each of the encoded data units is transmitted on the grant-free resources, and time-divided units of the radio access interface for transmitting uplink data on the grant-free resources. a temporal start position of the transmission period in one, wherein the temporal start position and the transmission period are independent for each of the plurality of configurations. Independent configurations may provide different temporal starting positions and transmission periods, which may better match the time at which the uplink data is generated, as a result of which the uplink data is transferred with lower latency in grant-free resources. can be sent.
