摘要： Systems and methodologies are described that facilitate grouping pilot identifies to indicate type and/or classification information regarding one or more access points. The access points can select or be assigned pilot identifiers from the group indicating a type or classification related to the access points. Thus, identifiers can be grouped into macrocell and/or femtocell groups or ranges such that an access point can indicate, and mobile devices can efficiently determine, whether the access point provides macrocell or femtocell coverage based on a range from which its pilot identifier is selected or assigned. In addition, the pilot identifiers can be utilized to indicate restricted association information regarding the access points.

摘要： Systems and methodologies are described that facilitate transmitting access point types and/or restricted association parameters using broadcast signals, such as beacons, pilot signals, etc. The type or restricted association information can be indicated by one or more intrinsic aspects of the signal, such as specified parameters. In addition, the type or information can be indicated by one or more extrinsic signal aspects, such as frequency, interval, periodicity, etc. Using this information, a mobile device can determine whether an access point implements restricted association. If so, the mobile device can request an access point or related group identifier before determining whether to establish connection therewith. The identifier can be verified against a list of accessible access points and/or groups to make the determination.

摘要： Systems and methodologies are described that facilitate silence interval specification and utilization in wireless communications. In particular, a silence interval can be defined such that communications cease during the interval, defined by an interval period, offset within the interval period, and duration; the communication can be that of mobile devices to base stations in a wireless communication network. In this regard, base stations can measure thermal noise during the silence to set a interference over thermal (IoT) level in one example. Additionally, other systems and networks can use the silence intervals to transmit, such as public safety devices and/or peer-to-peer communication. The wireless mobile devices can receive the silence interval information and appropriately blank out communications during the defined period.

摘要： Systems and methodologies are described that facilitate multiplexing control data values over a single physical control channel at least in part by dividing the control channel into one or more logical channels. The physical control channel can have a corresponding Walsh space for transmitting a number of bits, or representations thereof, and the Walsh space can be divided among the logical control channels. Additionally, the logical control channels and/or physical channel can be scrambled according to an identifier of a mobile device (such as MAC ID) to differentiate the data on the channel. Furthermore, a sector identifier can be used to scramble the data where the sector is ascertainable.

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.
