Abstract: Transmission techniques are provided that improve service continuity and reduce interruptions in delivery of content that can be caused by transitions that occur when the User Equipment (UE) moves from one cell to the other, or when the delivery of content changes from a Point-to-Point (PTP) connection to a Point-to-Multipoint (PTM) connection in the same serving cell, and vice-versa. Such transmission techniques enable seamless delivery of content across cell borders and/or between different transmission schemes such as Point-to-Multipoint (PTM) and Point-to-Point (PTP). Mechanisms for adjusting different streams and for recovering content from each data block during such transitions are also provided so that data is not lost during a transition. In addition, mechanisms for realigning data during decoding at a receiving terminal are also provided.

Abstract: A method and apparatus manages resources in a wireless communication system by transmitting a multi-carrier switch command message to an access terminal instructing the access terminal to switch between a diversity mode where each antenna module of a plurality antenna modules receives a single carrier signal transmitted at a single carrier frequency and a multi-carrier mode where a first antenna module of the plurality antenna modules receives a first multi-carrier signal transmitted at a first carrier frequency and a second antenna module receives a second multi-carrier signals transmitted at a second carrier frequency.

Abstract: A method and an apparatus for secure registration for a multicast-broadcast-multimedia system (MBMS) are disclosed. A random number is generated by a broadcast-multicast-service center (BM-SC) and broadcast to user equipment in the coverage area of a radio access network (RAN). A memory module or smart card (UICC) in the user equipment generates a radio access network key (RAK) which is a function of the random number and a key selected from the group consisting of a public land mobile network key (PK) and a broadcast access key (BAK), and then generates a temporary registration key (RGK) as a function of the RAK, a service identification number and a user identification number, for example, P-TMSI, which may be extracted by the RAN to authenticate the registration as legitimate.

Abstract: Methods and apparatus are disclosed herein for providing incremental redundancy in a wireless communication system to aid in error recovery. One or more redundancy versions are sent on different carriers than the primary version of information to be transmitted. At the receiver end the redundancy versions may be combined using hard or soft combining techniques, including selection combining, selective soft combining or soft combining.

Abstract: A remote station for a wireless communication system including a base station is disclosed. The remote station includes a front end structure configured to receive packet data in parallel on a subset of carrier frequencies. Each packet data is preceded by a header field for identifying the remote station as the recipient of the packet data and the subset of carrier frequencies is based on a set of a corresponding number of multiple carrier frequencies.

Abstract: Method for segmented message transmission wherein each message is first divided into segments and the segments are fragmented. A segment parameter is applied to each segment, and a segment identifier to each fragment. The fragments are provided to a lower level for preparation into frames for transmission. One embodiment is applied to the transmission of short duration messages, such as control messages. On receipt of a frame within a segment, a timer is initiated having an expiration period. Receipt of a next frame in the segment stops the timer. Expiration of the expiration period for a timer indicates that a next sequential frame is lost.

Abstract: In a communication system (100), a method and apparatus provide for efficient control of call requests from mobile stations (102-104) to base station (101). Mobile station (102-104) receives an initial call request block probability from base station (101), determines an elapsed time from an effective time of the initial call request block probability, and adjusts the initial call request block probability based on an elapsed time. Mobile station (102-104) uses the adjusted initial call request to block call request.

Abstract: An apparatus for providing a Time Division Multiplexing (TDM) scheme for link adaptation including use of channel estimation and Channel Quality Indicator (CQI) measurements by bundling several timeslots of a frame within the existing GSM/GPRS/EDGE system. An algorithm for providing rotation of MS users such that each one will benefit from measuring all timeslots of the frame resulting in more reliable and accurate transmission of information.
