In one embodiment, a method can be performed by a network controller of the wireless communication system. The method includes classifying each available channel in the wireless communication system into one of multiple channel categories according to performance and usability characteristics of each available channel. The method also includes ranking the channels per each category and assigning, according to the channels as ranked, at least one of the channels to each of the end-nodes. The method includes providing, in a channel list and to the end-nodes, information of which at least one channel has been assigned to each end-node.

Channel assignment in a wireless communication system

A packet transmitter in a wireless communication system can perform a method for preparing transmission of physical layer protocol data units (PDUs). The method includes detecting a need to transmit a second stream of symbols having higher priority than a first stream of symbols currently being transmitted from the packet transmitter to a packet receiver. The first and second streams of symbols are each part of a respective physical layer PDU. A dedicated tag is inserted after a recent-most transmitted symbol of the first stream of symbols. The dedicated tag indicates that the first stream of symbols is subjected to pre-emption at the physical layer. Symbols of the second stream of symbols are inserted following the dedicated tag for transmission of the second stream of symbols to the packet receiver.
