Abstract: Interference that occurs during wireless communication may be managed by subframe time reuse. A method, apparatus amend medium of communication determines interfering subframe gating sequences. The transmission gating in a home access point is adjusted by determining a first gating sequence from a first unplanned access point. A second gating sequence is selected based on the first gating sequence, wherein the first and second gating sequences are non-interfering. Signals are transmitted according to the second gating sequence from a second unplanned access point to an associated access terminal.

Abstract: Method and apparatus for encrypting transmission traffic at separate protocol layers L1, L2, and L3 so that separate encryption elements can be assigned to separate types of transmission traffic, which allows the implementation of different levels of encryption according to service requirements. Encryption elements use variable value inputs, called crypto-syncs, along with semi-permanent encryption keys to protect from replay attacks from rogue mobile stations. Since crypto-sync values vary, a method for synchronizing crypto-syncs at the mobile station and base station is also presented.

Abstract: Method and Apparatus for Processing Shared Sub-packets in a Communication System are disclosed. A communication system providing both voice and data services allows for a plurality of subscriber station to share a data sent in a unit of a forward traffic channel. To provide information required by the subscriber stations to determine that a unit of the forward traffic channel is shared, and to correctly decode the data, different control channel structures are described. Additionally, the control channel structures provides for more efficient signaling of code channel assignment.

Abstract: A dynamic shared forward link channel (or “data” channel) is used to send multicast data to a group of wireless devices, e.g., using a common long code mask for the data channel. Reference power control (PC) bits are also sent on the data channel and used for signal quality estimation. A shared forward link control channel is used to send user-specific signaling to individual wireless devices, e.g., using time division multiplexing (TDM) and a unique long code mask for each wireless device. A shared forward link indicator channel is used to send reverse link (RL) PC bits to the wireless devices, e.g., using TDM. The data channel is jointly power controlled by all wireless devices receiving the data channel. The control and indicator channels are individually power controlled by each wireless device such that the signaling and RL PC bits sent on these channels for the wireless device are reliably received.

Abstract: Techniques for efficient allocation of channelization codes are disclosed. In one aspect, a dedicated data channel is partitioned into a primary channel and a secondary channel.

Various other aspects are also presented. These aspects have the benefit of efficient code resource allocation, resulting in increased support for users/and or channels, as well as increased system capacity.

Abstract: An apparatus and method provides for controlling communications from multiple base stations to a mobile station in a communication system. A mobile station transmitter transmits from the mobile station channel quality indicator data of a first base station. The data is covered with Walsh code assigned to the first base station. A base station receiver receives the transmission of the channel quality indicator data of the first base station.

Abstract: A method for coherent estimation of the traffic-to-pilot energy ratio is presented. A received preamble is decoded, and then re-encoded. The received preamble is then multiplied by the re-encoded preamble. The results are summed, squared, and then divided by a pilot energy value. In another method, a message carrying energy information can be inserted between a subpacket preamble and a subpacket.

Abstract: Embodiments disclosed herein address the need in the art for reduced overhead control with the ability to adjust transmission rates as necessary. In one aspect, a first signal indicates an acknowledgement of a decoded subpacket and whether or not a rate control command is generated, and a second signal conditionally indicates the rate control command when one is generated. In another aspect, a grant may be generated concurrently with the acknowledgement. In yet another aspect, a mobile station monitors the first signal, conditionally monitors the second signal as indicated by the first signal, and may monitor a third signal comprising a grant. In yet another aspect, one or more base stations transmit one or more of the various signals. Various other aspects are also presented. These aspects have the benefit of providing the flexibility of grant-based control while utilizing lower overhead when rate control commands are used, thus increasing system utilization, increasing capacity and throughput.

Abstract: An encoder receives an input bit stream and generates, based on the input bit stream, a first output bit stream based on at least a first polynomial and a second output bit stream based on at least a second polynomial. The first and second polynomials are each different from each other. The encoder forms a first packet of code symbols, having a first code rate, based on bits from the first output bit stream. A transmitter transmits the first packet. A receiver receives a first negative acknowledgment indicating unsuccessful decoding of the first packet after transmitting of the first packet. The encoder punctures bits from the second output bit stream and forms a second packet of code symbols having a second code rate. The second code rate is different from the first code rate. The transmitter transmits the second packet in response to the receiver receiving the first negative acknowledgment.

The adjusted threshold may be one of, or any combination of, a pilot signal search threshold, a lock/unlock threshold, and a combine/un-combine threshold. The number of available fingers (110) may change after the threshold is adjusted.

Abstract: A method and apparatus for controlling the transmission of signals from one or more of a plurality of mobile stations to a base station on a plurality of M multiple access channels is described. A power control information packet formed from a plurality of power control bits is transmitted from the base station to the one or more mobile stations. Each of the power control bits in the power control information packet has a position that is mapped to a selected access channel and to a time offset within the selected access channel. The power control information packet is received at a first mobile station. A message is then transmitted from the first mobile station to the base station on a first access channel and at a first time offset associated with the first access channel.

Abstract: In a communication system capable of variable rate transmission, scheduling of high speed data transmission improves utilization of the forward link and decreases the transmission delay in data communication. Each remote station is assigned one primary code channel for the duration of the communication with a cell. Secondary code channels of various types and transmission capabilities can be assigned by a channel scheduler for scheduled transmission of data traffic at high rates. Secondary code channels are assigned in accordance with a set of system goals, a list of parameters, and collected information on the status of the communication network. Secondary code channels can be grouped into sets of secondary code channels. Data is partitioned in data frames and transmitted over the primary and secondary code channels which have been assigned to the scheduled user.
