摘要： Techniques for selecting a serving base station for a terminal in a wireless communication network are described. In one design, multiple candidate base stations for the terminal may be identified, with each candidate base station being a candidate for selection as the serving base station for the terminal. The multiple candidate base stations may include base stations with different transmit power levels and/or may support interference mitigation. One of the multiple candidate base stations may be selected as the serving base station. In one design, the serving base station may be selected based on at least one metric for each candidate base station. The at least one metrics may be for pathloss, effective transmit power, effective geometry, projected data rate, control channel reliability, network utility, etc. The selected candidate base station may have a lower SINR than a highest SINR among the multiple candidate base stations.

摘要： An access point is configured based on acquired information. An access point may be configured based on the configuration(s) of at least one other access point. An identifier to be transmitted by an access point may be selected based on the identifier(s) transmitted by at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to a configuration server and the configuration server may respond with a list of neighboring access points for that access point. A configuration server may provide configuration information to an access point based on the location of the access point. A configuration server also may direct an access point to a different configuration server.

摘要： Providing for management of wireless communications in a heterogeneous wireless access point (AP) environment is described herein. By way of example, system data of an over-the-air message can be configured to include information identifying a distinct type of transmitting base station. In some aspects, the information can include an access type of the base station and/or a sector ID for distinguishing the base station among large numbers of other base stations. According to other aspects, the information can include wireless channel resources designated for a particular type of base station, or blanked by the transmitting base station, to facilitate interference reduction on such resources. By employing aspects of wireless communication management disclosed herein, efficient and reliable communication can be affected in large heterogeneous AP networks.

摘要： Techniques for encoding and decoding data are described. In an aspect, multiple code rates for a forward error correction (FEC) code may be supported, and a suitable code rate may be selected based on packet size. A transmitter may obtain at least one threshold to use for code rate selection, determine a packet size to use for data transmission, and select a code rate from among the multiple code rates based on the packet size and the at least one threshold. In another aspect, multiple FEC codes of different types (e.g., Turbo, LDPC, and convolutional codes) may be supported, and a suitable FEC code may be selected based on packet size. The transmitter may obtain at least one threshold to use for FEC code selection and may select an FEC code from among the multiple FEC codes based on the packet size and the at least one threshold.

摘要： Beacon symbols are sent periodically from the base stations in an OFDM system. The entire power of the base station, or a large portion of it is concentrated in these symbols, thus they are very easily recognized by the mobile stations. The frequencies upon which these symbols are transmitted and the time at which they are transmitted communicates information such as the base station/sector identity and the preferred carrier of the given base station/sector to the mobile station. In order to avoid collision between the beacon symbols of different base stations and sectors, the beacon symbols from different base stations/sectors are transmitted at different symbols times and on different subcarriers.

摘要： Techniques for using wireless devices to implement sensor networks are described. For cognitive radio, a wireless device obtains measurements for a first system (e.g., a broadcast system) with which the wireless device is not in communication. The wireless device sends the measurements and associated location information and/or timestamps via a second system (e.g., a cellular system). A server receives measurements from a number of wireless devices and determines the coverage of the first system based on the measurements. For other applications, a wireless device obtains sensor information from at least one sensor at the wireless device and sends the sensor information and associated location information and/or timestamps via a wireless system. A server receives the sensor information and associated information from a number of wireless devices, aggregates the sensor information, and constructs a map. The wireless device may develop a user profile based on the sensor information and associated information.

摘要： Techniques for increased finger demodulation capability in a hardware efficient manner are disclosed. In one aspect, I and Q samples are shifted into a parallel-accessible shift register. A plurality of chip samples are accessed from the shift register and operated on in parallel to produce a multi-chip result for a channel each cycle. These multi-chip results can be accumulated and output to a symbol-rate processor on symbol boundaries. The scheduling of shift register access, computation, and accumulation can be scheduled such that the hardware is time-shared to support a large number of channels. In another aspect, time-tracking of a large number of channels can be accommodated through channel-specific indexing of the contents of the shift register file. These aspects, along with various others also presented, provide for hardware efficient chip rate processing capability for a large number of channels, with a high degree of flexibility in deployment of those channels.

摘要： Systems and methods are described that facilitate controlling transmission/ reception time slots in a wireless multi-hop ad hoc network. A node, such as an access terminal or an access point, may select an identifier that corresponds to specific time slots during which nodes with that particular identifier may transmit and/or receive. Nodes that are one hop away from each other may select different identifiers in order to ensure that neighboring nodes do not transmit and/or receive during the same time slots. In this manner, interference caused and/or experienced by a given node may be reduced.

摘要： Systems and methodologies are described that facilitate reducing rank (e.g., of a user device) as a number of transmissions there from increases. Such rank step-down can improve interference resistance and facilitate maintaining code rate despite transmission propagation. Additionally, rank step-down information can be encoded along with CQI information to generate a 5-bit CQI signal that can facilitate updating a user's rank upon each CQI transmission (e.g., approximately every 5 ms). The described systems and/or methods can be employed in a single code word (SCW) wireless communication environment with a hybrid automatic request (HARQ) protocol.
