摘要： Systems and methodologies are described that facilitate recovering from error due to false detection of completion signals at an access terminal. An access terminal specific request signal can be sent to a target base station to initiate handoff or semi-connected state exit. A completion signal can be transferred in response to the access terminal specific request signal. To mitigate errors stemming from false detection of the completion signal at the access terminal, forward link and reverse link confirmation signals can be transferred to confirm successful handoff or connected state re-entry completion. For example, the access terminal can determine handoff or re-entry to be successful when a forward link confirmation signal is detected prior to expiration of a timer. Moreover, the forward link and reverse link confirmation signals can each include more CRC bits as compared to a number of CRC bits included in the completion signal.

摘要： Techniques for transmitting pilot and traffic data are described. In one aspect, a terminal may scramble its pilot with a scrambling sequence generated based on a set of static and dynamic parameters. The static parameter(s) have fixed value for an entire communication session for the terminal. The dynamic parameter(s) have variable value during the communication session. The terminal may generate a scrambling sequence by hashing the set of parameters to obtain a seed and initializing a PN generator with the seed. The terminal may then generate the pilot based on the scrambling sequence. In another aspect, the terminal may use different scrambling sequences for pilot and traffic data. A first scrambling sequence may be generated based on a first set of parameters and used to generate the pilot. A second scrambling sequence may be generated based on a second set of parameters and used to scramble traffic data.

摘要： Systems and methodologies are described that facilitate indicating a dominant interferer to a target serving base station in a wireless communication environment. A mobile device can detect presence or absence of a dominant interferer. Further, an access probe that includes information related to the presence or absence of the dominant interferer can be generated. For example, the information can be included in a payload of the access probe as an explicit flag, an explicit indication of an interference level, a Channel Quality Indicator (CQI) value (e.g., reserved versus non-reserved,...), etc. Moreover, the access probe can be transmitted to the target serving base station to initiate an access procedure. The target serving base station can select a time-frequency resource to be utilized for a responsive downlink transmission (e.g., access grant signal, subsequent access related message,...) as a function of the information included in the access probe.

摘要： Techniques for transmitting null pilots to support interference estimation in a wireless network are described. A null pilot is non-transmission on designated time-frequency resources by a cell or a cluster of cells supporting cooperative transmission to a UE. The received power of the null pilot from the cell or cluster of cells may be indicative of interference from other cells. In one design, a cell in the cluster may determine resources for sending a null pilot by the cell. The cell may transmit the null pilot (i.e., send no transmissions) on the resources to allow UEs to estimate out-of-cluster interference. Some or all cells in the cluster may transmit null pilots on the same resources. The cell may receive interference and channel information from the UE and may send data transmission to the UE based on the interference and/or channel information. Remaining cells in the cluster may reduce interference to the UE.

摘要： Techniques for managing interference in a wireless network are described. In an aspect, reduce interference requests and interference indicators may be used for interference management to enable operation in scenarios with dominant interferers. In one design, a terminal may receive a reduce interference request from a first base station requesting lower interference on specified time-frequency resources. The terminal may also receive an interference indicator conveying the interference observed by a second base station. The terminal may determine its transmit power based on the reduce interference request and the interference indicator. For example, the terminal may determine an initial transmit power based on the reduce interference request (or the interference indicator) and may adjust the initial transmit power based on the interference indicator (or the reduce interference request) to obtain its transmit power. The terminal may transmit data to a serving base station at the determined transmit power.

摘要： Systems and methodologies are described that provide techniques for performing adjustments for delta-based power control and interference management in a wireless communication system. A terminal can utilize one or more delta-based power control techniques described herein upon engaging in a reverse link transmission after a predetermined period of silence or after receiving indications of interference from neighboring access points. A delta value can be computed through open-loop projection, based on which transmission resources such as bandwidth and/or transmit power can be increased or decreased to manage interference caused by the terminal. A delta value, other feedback from the terminal, and/or indications of interference caused by the terminal can also be communicated as feedback to a serving access point to allow the access point to assign transmission resources for the terminal.

摘要： Systems and methodologies are described that facilitate mitigation of interference in a wireless communication environment. Terminals can utilize interference information provided by neighboring sectors to adjust transmit power and reduce interference. Access points can provide two sets or types of interference information. The first type can be transmitted over a large coverage area, requiring significant overhead and limiting the transmission rate. Access points can also provide a second set or type of interference information directed at smaller coverage area, such as an area proximate to the edge of the supported sector. This second type of interference information can be utilized by terminals that include the access point within their active set. The second set of interference information can be provided at a higher rate than the first set due to decreased overhead requirements. Terminals can utilize both sets of interference information to adjust transmit power.

摘要： Systems and methodologies are described that facilitate soft handoff and enhanced performance in a wireless communication environment. In multiple access systems, access points assign certain resources (e.g., time, frequency, code) to each terminal. This assignment information can also be provided to neighboring sectors, allowing such sectors to receive and decode terminal transmissions. The information can be provided via backhaul signaling. Decoding by sectors within the active set of the terminal facilitates smooth transition as terminals move between sectors during soft handoff. In addition, sectors can signal successful receipt and decoding of transmissions, avoiding redundant processing.

摘要： Providing for improved access communication for wireless systems is described herein. By way of example, wireless devices can employ wireless resource re-use in selecting a subset of access communication resources, to mitigate interference on uplink access requests. Re-use can be based on current network conditions, or on a type of base station facilitating the wireless communication. In some aspects, planned resource re-use can be facilitated by an access terminal. The access terminal requests neighboring or interfering network access points to reserve a set of resources for a serving access point. Reserved resources can be conveyed to the serving access point with an uplink access probe, to further mitigate interference.

摘要： Systems and methodologies are described herein that facilitate interference control and resource management in a wireless communication system. As described herein, a base station, terminal, and/or other entity in a wireless communication system that observes interference from one or more other network entities can construct and communicate resource utilization messages (RUMs) in order to request the interfering network entities to conduct power backoff on designated resources. Parameters constructed as a function of quality of service (QoS) and/or priority metrics (such as head-of-line delays, queue lengths, burst sizes, delay targets, average rates, or the like) can be included within the RUM, such that an entity receiving the RUM can compute QoS changes associated with various power backoff levels in order to select a power backoff level that maximizes overall system QoS performance.
