摘要： A method and apparatus for extending the sequence numbering range for a selective repeat transmission protocol is described. In accordance with one embodiment of the invention, data frames are transmitted including an eight-bit sequence number and a one-bit retransmit flag. The one bit retransmit flag indicates whether the frame is newly transmitted or retransmitted due to a failed first transmission. The transmit and receive systems each maintain a twelve-bit sequence number referred to as a "long sequence numbers" comprised of the eight-bit sequence number transmitted with each frame and a four-bit extension. The long sequence number is transmitted within control frames and the eight-bit sequence number is transmitted within the data frames.

摘要： Embodiments disclosed herein relate to carrier allocation and management in multi-carrier communication systems. In some embodiments, the number of carriers assigned to an access terminal on a forward link may be determined by an access network, and the number of carriers assigned to the access terminal on a reverse link may be based on a cooperative process between the access terminal and the access network. In other embodiments, the number of carriers assigned to the access terminal on the reverse link may also be determined by the access network, e.g., in relation to the scheduling information received from the access terminal.

摘要： Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. Information to be transmitted is provided to a systematic portion of a plurality of transmit buffers and encoded by an outer decoder communicatively coupled to the transmit buffer. The resulting redundant bits are provided to a parity portion of each transmit buffer. The content of the transmit buffers, is multiplexed and encoded by an inner decoder to improve protection by adding redundancy. The receiving station recovers the transmitted information by an inverse process. Because a decoding complexity depends on the size of a systematic portion of the transmit buffer, reasoned compromise between a systematic portion size and number of transmit buffers yields decreased decoding complexity.

摘要： Techniques to support handover of a terminal from a source base station to a target base station are described. In one design, a determination is made whether a change in personality is requested by the terminal. If the answer is ‘Yes’, then the personality of the terminal may be switched by sending one or more appropriate messages. The connection and RLP for the terminal may be reset due to the change in personality. A buffer of data reported by the source base station as being served to the terminal (e.g., no NAK was sent) may be saved by a BSC/PCF. The buffer of data may be sent to the target base station when handover occurs. New data may thereafter be sent to the target base station. This buffer of duplicate data may avoid both loss of data and retransmission timeout by TCP during the handover.

摘要： Techniques for dynamically varying coverage in a multi-carrier communication system are described. A sector may operate on multiple carriers. The sector may vary coverage on a given carrier k based on its load, so that less interference may be caused to other sectors when the sector load is light. In one design, the sector may communicate on a first carrier at a first transmit power level and on a second carrier at a second transmit power level equal to or lower than the first transmit power level. The sector may vary the second transmit power level based on its load to vary the coverage of the second carrier. The sector may reduce the second transmit power level to zero or a low level if the sector load is light. The sector may also vary the second transmit power level based on a function of sector load or a switching pattern.

摘要： A cryptosync design comprising (1) a channel identifier indicative of a particular channel via which a data packet is sent, (2) an extended time stamp indicative of a time value associated with the data packet, and (3) a counter indicative of a packet count associated with the data packet. The lengths of the extended time stamp and counter fields and the time unit for the extended time stamp are parameters that may be configured for each channel. At the sender, the extended time stamp for the cryptosync may be obtained from the System Time maintained by the sender. The counter value for the cryptosync may be provided by a counter that is maintained for the channel by the sender. The sender may include a time stamp and/or the counter value, if they are needed to derive the cryptosync at the receiver, in a header of the data packet.

摘要： Techniques for efficient storage and retrieval of Preferred Roaming Lists are disclosed. In one aspect, PRL entries are stored in two tables. One table contains records that are common to two or more PRL entries. Another table stores any information that is unique to a PRL entry, as well as an indicator of which common record is associated with it. The common record is concatenated with the unique information to generate the uncompressed PRL entry. Various other aspects of the invention are also presented. These aspects have the benefit of reducing the memory requirements for storing a PRL. In addition, time required to download the compressed PRL is reduced.

摘要： Embodiments disclosed herein relate to methods and systems for grouping pilot signals and using such grouping for pilot strength reporting and set management in multi-carrier communication systems. In one embodiment, an access network may assign a group identifier (or “group ID”) to each of the pilot signals associated with the sector, e.g., based on the coverage areas of the pilot signals, and transmit the pilot signals with the corresponding group IDs. PN offset may be used as the group ID. An access terminal may group the pilot signals received into one or more pilot groups in accordance with their group IDs, and select a representative pilot signals from each pilot group for pilot strength reporting. The access terminal may also use the pilot grouping to perform effective set management.
