    摘要: Techniques for reliable transmission of higher priority data within a frame are disclosed. In one aspect, an inner code is applied to one or more partial segments of a transmitted data frame in addition to any outer code applied to the entire frame. In another aspect, inner coded segments of a received frame are decoded when decoding of the outer code indicates one or more errors within the frame. The inner coded segment is retained when the inner decoding decodes without error. Various other aspects are also disclosed. These aspects have the benefits of reducing the number of retransmissions of higher priority data, as well as reducing delay for time-sensitive segments of the frame. The result is more efficient use of bandwidth, more responsiveness to higher priority segments, such as signaling traffic, and capacity, power, and other efficiencies associated therewith.

    摘要: Systems and methodologies are described that facilitate inter-system handover in a wireless communication system. Various aspects described herein provide for handover techniques that enable a target system to be prepared by a mobile device via a source system in order to minimize specific changes required to source system and/or target system. Techniques are described herein in which the radio link of a source system can be utilized to tunnel signaling messages which are in a format understood by a destination node in a target system. Further, fast inter-access handover can be facilitated by establishing a simple generic transmission tunnel between respective network nodes in source and target systems that handle intra-system mobility and providing a Layer 2 (L2) tunneling mechanism over the radio interface of each involved system technology.

    摘要: Systems and methodologies are described that facilitate enabling multiple address access between two or more networks. A home agent can update a binding cache with a particular proxy binding update (PBU) to include two or more network gateway IP addresses associated with a user equipment (UE) within two or more networks or systems. When the UE in idle mode moves between networks or systems to which registration has occurred, an attachment procedure is not performed since the home agent includes the network gateway IP addresses related to such UE. Thus, inter-system idle mode mobility is enabled without having to perform a full attachment, re-registration, or de-registration based on the network location of the UE.

    摘要: Techniques for transmitting data and training sequence efficiently using new slot and block formats are described. A transmitter processes (e.g., encodes, interleaves, and partitions) a data block to obtain multiple output blocks. For each output block, the transmitter generates multiple bursts having a training sequence that is shared by these bursts. The transmitter sends the multiple bursts for each output block in multiple time slots, e.g., consecutive time slots in one frame. The multiple bursts for each output block may (1) include one or more short training sequences, (2) omit guard periods between adjacent bursts, (3) include a first tail bit field at the start of the first burst and a second tail bit field at the end of the last burst, (4) include at least one stealing flag field, or (5) have any combination of the above.

    摘要: Techniques for supporting policy control and charging (PCC) functions in a wireless communication network are described. In one design, a Policy Control and Charging Rules Function (PCRF) may receive a request from a first network entity (e.g., a home agent) to establish a PCC session for a user equipment (UE) accessing the first network entity using a mobility protocol (e.g., Mobile IP). The PCRF may determine the mobility protocol used by the UE based on an IP-CAN Type parameter included in the request. The PCRF may determine PCC rules for the PCC session based on the mobility protocol and may send the PCC rules to the first network entity. The first network entity may apply the PCC rules on packets for the PCC session and may count each packet for charging. A second network entity may forward the packets but would not count these packets for charging.

    摘要: A control scheme using packet headers allows GSM EDGE Radio Access Network (GERAN) systems to increase spectral efficiency through multiplexing techniques, such as superposition coding, multi-user packet transmission, joint detection, and/or joint decoding. A fast feedback scheme for GERAN allows Voice over Internet Protocol (VoIP) frames to be transmitted over GERAN air interfaces without excessive feedback latency. As a result, Hybrid Automatic Repeat-reQuest (H-ARM) acknowledgements may be timely provided for end-to-end VoIP calls that traverse GERAN air interfaces. Additionally, Incremental Redundancy H-ARQ and link quality feedback latencies are decreased.

    摘要: A method and apparatus resolves conflicts and ambiguities of GSM standards arising in DTM by monitoring only selected downlink timeslots for uplink status flags (USFs). Downlink timeslots with a packet data channel (PDCH) are monitored for a USF from a lowest numbered time slot, B(0), to a maximum time slot B(MAX) where B(MAX) is equal to the lowest transmission uplink timeslot, B(x), in the corresponding TDMA uplink frame if the second lowest transmission uplink timeslot B(x)+1, is a circuit switched timeslot and where B(MAX) is equal to the second lowest transmission timeslot in the corresponding TDMA frame, B(x)+1, otherwise.
