Abstract:
A method in a wireless communication system for inserting, into a data stream, data for a near-real-time transmission having a duration and requiring low latency, the data stream also serving a plurality of store-and-forward transmissions which do not require low latency, without disrupting the data stream for longer than said duration, the method comprising the steps of:queuing the plurality of store-and-forward transmissions in a corresponding plurality of blocks of data having a predetermined length; sending the plurality of blocks of data to a transmitter; storing the plurality of blocks of data in the transmitter in preparation for transmission; determining a need to transmit the data for the near-real-time transmission; and replacing, at the transmitter, a block of the plurality of blocks of data that has been received but has not yet been transmitted with the data for the near-real-time transmission and modifying an error detection portion of the data in a manner that prevents use of the error detection portion, in response to the determining step.
