摘要： Systems and methodologies are described that provide efficient channel assignment and communication for a wireless communication network. System resources can be allocated for a traffic channel for communication between a base station and a terminal in a physical layer frame, a portion of which can be made available for an acknowledgement channel. Resources for the acknowledgement channel can then be allocated such that the resources allocated for the acknowledgement channel occupy only a portion of the resources available for the acknowledgement channel within the resources allocated for the traffic channel. By scheduling the acknowledgement channel such that it occupies only a portion of the resources available to it, traffic data and acknowledgements can be communicated in the wireless communication system on their respective channels more efficiently.

摘要： Softer handoff groups are provided utilizing fractional frequency reuse set, which can be managed by a single master sector that is part of the group. The group can based on handoff rules that can include a group indication by an access point or a group request by an access terminal. A terminal is provided functionality to select a softer handoff group, which can be indicated by an active set update. An access point can discontinue serving terminals by groups by reducing an active set size to one. Diversity can be provided such that if a transmission from one sector fades, the other sector can provide the transmission, mitigating loss of data. Thus, robustness against inadequate channel conditions can be obtained.

摘要： System(s) and method(s) are provided to facilitate generating and processing acquisition pilots in wireless communications. Acquisition pilots that convey timing and frequency synchronization information, wireless system acquisition and system determination information are modulated with pseudorandom sequences. The R bits of information carried by the acquisition pilot that conveys system determination information are augmented with T bits that convey a counter index associated with the system timing of superframes transmitted from an access point. The processing overhead resulting from the addition of the T bits is offset by the advantages afforded to a wireless communication. Salient advantages include: (i) processing gain at a receiver for communication in a specific sector during asynchronous operation, (ii) packet boundary determination through the counter field values, and (iii) initialization of various pseudorandom registers employed for communication.

摘要： Systems and methodologies are described that facilitate establishing a forward link acknowledgement channel and transmitting acknowledgment signals thereupon. In particular, the signals can be spread within contiguous channel clusters in a tile where the signals in the cluster are mutually orthogonal to one another. Additionally, the signals can be multiplexed over a plurality of frequency regions. In this regard, the acknowledgment signals are diverse with respect to frequency and interference; moreover, the signals can be received and decoded even where one of the channels experiences high interference. Furthermore, the acknowledgement signals can also communicate a channel deassignment value, which allows devices to utilize persistent channels in communicating data to one another

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 generate pilots for signal acquisition in a wireless communication system based on time domain sequences. The pilots may be generated by a base station and transmitted in a pilot field to one or more access terminals to aid in signal acquisition at each of the access terminals. One of the pilots may be common to all access points in the wireless communication system, thereby allowing an access terminal to obtain a timing estimate for the system while minimizing the effects of interference variations between base stations. Further, one or more generated pilots may be unique to each access point in order to allow each respective access point to be identified by its generated pilots.

摘要： Techniques for allocating and mapping resources in a wireless communication system are described. The system may use hop-ports to facilitate allocation and use of subcarriers. In one aspect, the hop-ports may be partitioned into multiple subzones, with each subzone including a configurable number of hop-ports. The hop-ports within each subzone may be permuted or shuffled based on a permutation function. After permutation, the hop-ports in all subzones may be mapped to the subcarriers based on local or global hopping. In another aspect, a set of hop-ports may be mapped to a set of subcarriers. A hop-port may be mapped to an unavailable subcarrier and may then be remapped to another available subcarrier. In yet another aspect, a set of hop-ports may be mapped to a set of subcarriers distributed (e.g., evenly) across all subcarriers but avoiding subcarriers in a reserved zone.
