Abstract: A control network communication arrangement includes a second protocol embedded into a first protocol in a way that modules supporting the second protocol may be aware of and utilize the first protocol whereas modules supporting only the first protocol may not be aware of the second protocol. Operation of modules using the second protocol does not disturb operation of the modules not configured to use or understand the second protocol. By one approach, the messages sent using the second protocol will be seen as messages sent using the first protocol but not having a message necessary to understand or as needing a particular response. In another approach, modules using the second protocol can be configured to send messages within a CAN message frame without being compatible with CAN.

Abstract: Each of terminal devices 3 belongs to one of groups, starts up at a startup time, and performs terminal processing within a communication time after an offset time is lapsed. A control device 2 uses a sum of the communication times of the terminal devices 3 belonging to the same group as the communication time of the group. The offset time is calculated for terminal devices 3 belonging to another group which performs the terminal processing subsequently to the terminal devices 3 belonging to the previous group, based on the communication time of the previous group. A next startup time for each terminal device 3 is determined based on the communication time and the offset time, and it is set to the terminal device 3.

Abstract: A group-based PDCCH capability in LTE. Information common to a group of UEs, such as those common to a virtual carrier, may be signalled in a group search space within the PDCCH. This common information may include the location of a further control region embedded in the virtual carrier which contains UE-specific information for access the resources of the virtual carrier. Additional methods assign UEs a group identity by implicit signalling, and determine the aggregation level of the group-based PDCCH search space.

Abstract: Provided is a method for communicating performed by a terminal in a wireless communication system. The method comprises receiving from a first access network a second access network search configuration for searching a second access network, and receiving traffic routing criteria from the first access network.

Abstract: A method apparatus and system for efficiently transmitting and receiving channels are provided in a wireless communication system based on Orthogonal Frequency Division Multiplexing (OFDM). A multiplexing scheme differs according to a channel when a transmitter transmits a packet data channel, a common control channel and a control channel designated for a particular user. Uncoded 1-bit information is broadly dispersed in frequency and time domains using multiplexing technology for maximizing diversity in a channel for transmitting information of at least one bit to a particular user like an acknowledgement (ACK) channel. The transmitter converts a sequence obtained by multiplexing multiple bits to be transmitted to a plurality of users to parallel signals, and broadly disperses the parallel signals in the time and frequency domains.

Abstract: A method for scheduling radio resource allocation among active flows within a wireless communication network. The method includes, at each working period of the scheduling method; for each active flow, checking presence of priority data to be transmitted within the current working period. Each active flow having priority data to be transmitted within the current working period is classified as a priority active flow. The remaining active flows are classified as non-priority active flows, the non-priority active flows having non-priority data that need not to be transmitted within the current working period. Radio resources are allocated among the priority active flows, and corresponding priority data are transmitted over the respective allocated resources. After completing priority data transmission, the radio resources are allocated among the non-priority active flows and corresponding non-priority data are transmitted over the respective allocated radio resources until the end of the current working period.
