摘要： For interference control, a sector m estimates interference observed from terminals in neighbor sectors and obtains an interference estimate. Sector m may generate an over-the-air (OTA) other-sector interference (OSI) report and/or an inter-sector (IS) OSI report based on the interference estimate. Sector m may broadcast the OTA OSI report to the terminals in the neighbor sectors. These terminals may adjust their transmit powers based on the OTA OSI report. Sector m may send the IS OSI report to the neighbor sectors, receive IS OSI reports from the neighbor sectors, and regulate data transmissions for terminals in sector m based on the received IS OSI reports. Sector m may control admission of terminals to sector m, de-assign admitted terminals, schedule terminals in sector m in a manner to reduce interference to the neighbor sectors, and/or assign the terminals in sector m with traffic channels that cause less interference to the neighbor sectors.

摘要： For Quality of Service (QoS) implementation in a multiple-access communication system, a base station processes data transmissions from terminals for all QoS classes supported by the system and obtains status information for the data transmissions. The status information may indicate whether each packet is decoded correctly or in error and the delay for each packet. For each QoS class, the base station derives one or more metrics based on the status information for data transmissions from disadvantaged terminals and updates the QoS parameter based on the metrics and requirements for the QoS class. The QoS parameter for each QoS class determines the transmit powers for the data transmissions sent for that QoS class. The base station broadcasts the QoS parameters for all QoS classes. Each terminal uses the QoS parameter for an applicable QoS class for power control of the data transmission sent to the base station.

摘要： A channel structure has at least two channel sets. Each channel set contains multiple channels and is associated with a specific mapping of the channels to the system resources available for data transmission. Each channel set may be defined based on a channel tree having a hierarchical structure. To achieve intra-cell interference diversity, the channel-to-resource mapping for each channel set is pseudo-random with respect to the mapping for each remaining channel set. In each scheduling interval, terminals are scheduled for transmission on the forward and/or reverse link. The scheduled terminals are assigned channels from the channel sets. Multiple terminals may use the same system resources and their overlapping transmissions may be separated in the spatial domain. For example, beamforming may be performed to send multiple overlapping transmissions on the forward link, and receiver spatial processing may be performed to separate out multiple overlapping transmissions received on the reverse link.

摘要： Techniques are provided to support multi-carrier code division multiple access (MC-CDMA) in an orthogonal uplink of a wireless communication system. A method of wireless multi-carrier communications comprises dividing sub-carriers on an uplink into non-overlapping groups, allocating a time-frequency block including a hopping duration and a non-overlapped group, respectively, assigning a different set of orthogonal codes to each user, spreading data (or pilot) symbols of each user over the allocated time-frequency block, wherein the data (or pilot) symbols of each user are spread using the different set of orthogonal codes assigned to each user, mapping each data (or pilot) symbol to a modulation symbol in the time-frequency block, generating an orthogonal waveform based on the mapped symbols, and transmitting the orthogonal waveform.

摘要： Systems and methodologies are described that facilitate providing time-division duplexed beam-forming support in traditionally non-time-division duplexed wireless systems, such as an OFDMA system, a WCDMA system, etc. According to an aspect, a base station can analyze pilot information, such as a portion of bandwidth over which a user device is transmitting, and can transmit on the downlink using pre-hopped portion of bandwidth utilized by the user device on the preceding reverse link time slot. The base station can additionally transmit bandwidth segment reassignments to the user device to facilitate bandwidth segment hopping between user devices served by the base station. Additionally, the base station can instruct the user device to provide on-demand pilot information to resolve ambiguity related thereto.
