摘要： Techniques to enhance the performance in a wireless communication system using CQI feedback optimized to support different scenarios. According to one aspect, an access terminal may select a CQI feedback table based on the access terminals capability. According to another aspect, an access point may select a CQI feedback table based on an access terminals capability, system loading and the type of service provided by the access point. An access point which provides services that require high data rates may select a larger CQI feedback table to support the high data rates for access terminals which support the larger CQI feedback table. The same access point may select a smaller CQI feedback table for access terminals which do not have the capability or need for the high data rate services.

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 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.

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, recieve 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： Method and apparatus for transmission of information in multiple access communication system is described. Information from a plurality of access terminals is received. Alternatively, an access terminal determines what information needs to be sent to the access point. A determination is made as to whether sufficient resources, such as time, power level, or channels, are available to send an indication of acknowledgment. If sufficient resources are not available at the given time, the transmission of an indication of acknowledgment is delayed until sufficient resources are available.

摘要： To transmit signaling, a base station obtains signaling (e.g., ACKs) for a group of channels used for data transmission and selected from a set of channels having constraints on usage. The base station compresses the signaling based on the channel constraints and obtains at least one message. If multiple messages are to be sent, then the assigned channels are partitioned into multiple subgroups, and the signaling for the channels in each subgroup is compressed to obtain a message for that subgroup. Each message is encoded at a spectral efficiency and transmitted at a power level selected for the message. A CRC value is appended to the message(s) for error detection. To receive the signaling, a terminal checks a received message with the appended CRC, decodes the message if the CRC passes, decompresses the decoded message based on the channel constraints, and extracts the signaling for an assigned channel.

摘要： Techniques for adjusting transmit power to mitigate both intra-sector interference to a serving base station and inter-sector interference to neighbor base stations are described. The amount of inter-sector interference that a terminal may cause may be roughly estimated based on the total interference observed by each neighbor base station, channel gains for the serving and neighbor base stations, and the current transmit power level. The transmit power may be decreased if high interference is observed by a neighbor base station and increased otherwise. The transmit power may be adjusted by a larger amount and/or more frequently if the terminal is located closer to the neighbor base station observing high interference and/or if the current transmit power level is higher, and vice versa. The intra-sector interference is maintained within an acceptable level by limiting a received SNR for the terminal to be within a range of allowable SNRs.
