摘要:
The present patent application comprises a method and apparatus for multiplexing reverse link feedback channels on a single reverse link frequency supporting multiple forward link frequencies for forward link channels, comprising assigning the reverse link frequency to a mobile station, assigning one or more of the forward link frequencies to the reverse link frequency, and code division multiplexing a plurality of the reverse link feedback channels on the reverse link frequency

Methods and apparatus related to management of active connections between an access terminal and access points are described. An access terminal maintains and manages active set information. The active set information identifies a set of access points with which the access terminal has an active connection. In some embodiments, the active set information includes allocated resources assigned to the access terminal corresponding to the different access points in the active set. Layer 2 Transport Tunneling is used, in various embodiments, to communicate connection request and/or connection response information, between access points. In some embodiments, the access terminal optionally assists in coordinating MAC resources allocated to the access terminal by different access points.

Embodiments disclosed herein relate to a new set of radio link protocols (RLPs) configured to provide for efficient data transmission in a multi-link communication system. In an embodiment, an upper-layer packet is segmented into link-layer packets to be transmitted over a plurality of communication links, each including a first sequence number in accordance with a predetermined order. A second sequence number is further added to each link-layer packet to be transmitted for the first time. The second sequence number is configured to be in a sequence space associated with a particular communication link, and may be used for detection of missing packets.
摘要:
A method and apparatus for efficiently transmitting location assistance information to a mobile communication device over a control channel with a minimal impact on the capacity of the control channel. A position location server provides a difference between satellite locations which have been computed using Almanac data and then Ephemeris data. Sending only the difference between the locations and satellite clock corrections computed using the two different data types, the total amount of information to be transmitted to a mobile communication device is significantly reduced. Furthermore, by providing rate of change information, the method and apparatus allows the location assistance information to remain valid for a relatively long time after it is has been received by the mobile communication device.
摘要:
A method for improving link efficiency in multicast transmissions is described. A data packet is sent to a multicast server. The data packet is processed. A copy of the data packet is transmitted from the multicast server to a multicast internet protocol (IP) address associated with one or more access terminals. The copy of the data packet is multicast to each of the one or more access terminals using a channel dedicated for multicast traffic that is associated with each of the one or more access terminals.
摘要:
A high data rate system capable of inter-frequency handoffs with little or no interruption in data service. The access network sends data from the first sector to the access terminal at the first frequency. The access terminal measures a parameter of a signal received at the access terminal from the second sector at the second frequency, wherein a pre-active set of the access terminal includes the second sector, and wherein an active set of the access terminal consists of one or more sectors operating in the first frequency. The access terminal then sends a data source control message corresponding to the second sector to the access network, after which the access terminal switches the pre-active set and the active set.
摘要:
Methods and systems to enhance local repair in robust header compression (ROHC) decompressors (110, 114), which may improve network transmission efficiency and quality. One method uses lower layer information to enhance local repair at the decompressor (110, 114). Another method uses a User Datagram Protocol (UDP) checksum to enhance local repair at the decompressor (110, 114).
摘要:
An access terminal an a wireless multiple-access network monitors multiple broadcast soft handoff groups simultaneously in order to select the best logical broadcast channels to decode based upon broadcast contents selected by a user of the access terminal. When in a traffic state the access terminal is able to decode one or more broadcast channels by decoding a unicast channel from a traffic server during one time slot and then decoding a broadcast channel from a broadcast server during another time slot.
