    Abstract: A base station uses a common link layer controller corresponding to multiple physical attachment points, facilitating multiple concurrent wireless connections between different base station sector physical attachment points and the same wireless terminal using the same link layer link. A wireless terminal maintains multiple simultaneous wireless connections for the same link layer link. A packet of user data is fragmented into a plurality of grouping of MAC frames, thus a packet portion can be communicated over a connection. A single packet is sometimes communicated with different portion s conveyed over different wireless connections. Automatic repeat request, implemented using the common link layer controller, allows for retransmissio n of a packet portion over a different connection than it was initially transmitted over. A wireless terminal sends connection request messages including lists of link layer identifiers associated with the wireless terminal. A base station sends response messages including an indication of whether logical link state was already present.

    IPC: H04B7/26

    Abstract: A multi-mode base station includes a transmit standby mode and an active mode. Transmit standby mode of base station operation is a low power/low interference level of operation as compared to active mode. In transmit standby mode at least some of the synchronization signaling such as pilot tone signaling is reduced in power level and/or rate with respect to the active mode. In transmit standby mode, the base station has no active state registered wireless terminals being serviced but may have some sleep state registered wireless terminals being serviced. Mode transitions from active to transmit standby may be in response to: a detected period of inactivity, scheduling information, base station mode change signals, and/or detected wireless terminal state transition. Mode transitions from transmit standby to active may be in response to: scheduling information, access signals, wake-up signals, hand-off signals, wireless terminal state change signals, and/or base station mode change signals.

    Abstract: A wireless terminal for communicating with a base station which supports a reduced synchronization signaling mode of operation and a full on synchronization mode of operation is described, the wireless terminal comprising: means for transmitting signals; means for determining if said base station is operating in said reduced synchronization signaling mode of operation; and means for controlling said means for transmitting to transmit a signal used to trigger the base station to transition into a more active synchronization signaling mode of operation when said means for determining that said base station is operating in said reduced synchronization mode of operation.
