摘要:
A radio communication system comprises an access station that is adapted and configured to transmit a rateless encoded multicast message to a plurality of radio terminals. Each of the radio terminals transmits a reply message to the access station upon successful reception of the multicast message, wherein the transmit resources are selected from a predefined set of agreed transmit resources, where the selection is influenced by certain characteristics of the reception of the multicast message.
摘要:
A radio communication method and a corresponding system are described. Time frequency resources are divided into a grid of resources. For communicating with a plurality of non-synchronized terminals the timing offset of each terminal is measured and a joint message is asynchronously transmitted to a subset of terminals, wherein the subset comprises at least two terminals.

摘要:
A communication method for a mobile communication system is described. Available radio resources, i.e. an available frequency band, are divided into a plurality of comparatively small radio resource units. The mobile communication system uses a first communication protocol for communicating with mobile stations compatible with the mobile communication system. For communicating with an autonomous terminal at least one radio resource unit is allocated, in which a second communication protocol incompatible with the first communication protocol is used for communicating with the terminal.
