摘要： In a wireless communication system, there is a method of transmitting over a reverse link, where a medium access control layer multiplexes data from upper level layers onto transport channels that are used based on whether the user is in a scheduled transmission mode or an autonomous transmission mode. The transport channels may be mapped to one or more physical channels associated with a particular transport channel, based on whether the transport channel is dedicated for use in the scheduled or autonomous mode.

摘要： Rather than transmitting a large full Broadcast-Multicast Services (BCMC) Parameters Message (BSPM) containing a full set of BSPM parameters pertaining to all active BCMC flows within a sector on an infrequent basis, smaller-sized differential or partial BSPMs are instead transmitted. Differential BSPMs contain updated information for existing flows or information for new flows, and because of their smaller size, can be transmitted more frequently than full BSPMs. A mobile terminal receiving a differential BSPM updates the flows with the information contained within the differential BSPM or adds the information contained within the differential BSPM for a new flow. Partial BSPMs divide the flow information contained in a large full BSPM over a plurality of smaller-sized partial BSPMs, which are separately and sequentially transmitted at different times. A mobile terminal receiving these partial BSPMs then reconstructs the full BSPM from a collection of received partial BSPMs.

摘要： In an ad hoc wireless network, for purposes of neighbor discovery, a transmitting node transmits a beacon within a timeslot and at a frequency that varies from timeslot-to-timeslot according to one or more associated and known pseudo-random or cyclical frequency hopping sequences. When, during a timeslot, the frequency hopping sequence would select a beacon frequency that if transmitted would violate spectrum policy that is in place during that timeslot, then, during that timeslot, a beacon is not transmitted during that timeslot. During each timeslot, a neighbor receiving node attempts to detect and decode a transmitted beacon at a frequency specified by the frequency hopping sequence that it expects a transmitting node to be using. When a receiving node successfully detects and decodes a beacon transmitted by a transmitting node, neighbor discovery between the transmitting and receiving nodes is achieved.

摘要： In a method of tracking a user in a communication network supporting a broadcast-multicast service, the network classifies groups of users into tracking areas. Movement of a user may be tracked as the user crosses a boundary between two tracking areas in the network. The method may enable a balance to be achieved between use of uplink overhead and the level or granularity of tracking desired, so as to conserve radio resources.

摘要： Methods for signaling information to a group of users in a communication network supporting a broadcast-multicast service are described, in which one or more indicator bits of a sequence may be assigned to indicate transmission of signaling information that is related to the group. The sequence may be transmitted to the group on a first channel, with the signaling information related to the group being transmitted on a second channel.
