Abstract: 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.

Abstract: An apparatus may receive, from a scheduling entity, sidelink grant information in a downlink control channel. After receiving the grant information in the downlink control channel, the apparatus may transmit a request-to-send (RTS) signal comprising an indication of a requested duration of time to reserve a sidelink channel for sidelink data. If the sidelink channel is available for the requested duration of time, the apparatus may receive a clear-to-send (CTS) signal configured to indicate an availability of the sidelink channel for the requested duration of time. Subsequently, the apparatus may communicate, with another apparatus different from the scheduling entity, the sidelink data using the sidelink channel during the requested duration of time. Afterwards, the apparatus may communicate acknowledgment information corresponding to the communication of the sidelink signal with the other apparatus. Various additional and alternative aspects are described herein.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to utilize a shared spectrum between two or more network operators. Coexistence between the different network operators on the shared spectrum may be provided by reserving resources for exclusive use by each of the network operators within a period of time that is variable based on the number of network operators. Non-exclusive use of resources may further be granted to one or more network operators in accordance with network operator priorities.

Abstract: In a communication system wherein a CDMA segment at each access point consists of multiple sub-segments a three frame transmission time interval (TTI) with eight retransmissions is utilized for data transmission. The access point not only specifies the interlaces to be utilized for data transmission it also assigns packet start interlaces for particular access terminals. An auxiliary pilot channel R-AuxPICH is transmitted by an access terminal along with CDMA data on reverse link. The ratio of R-AuxPICH to R-PICH is varied based on ACK/NACK feedback. A reverse link activity bit (RAB) which can be used as an emergency load-control mechanism for non-QoS flows is also disclosed.

Abstract: Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a serving base station may send a message to a terminal to trigger short-term interference mitigation. In response, the terminal may send a message to request at least one interfering base station to reduce interference on at least one resource. Each interfering base station may determine a transmit power level to be used for the at least one resource and may send a pilot at this transmit power level. The terminal may estimate the channel quality of the at least one resource based on at least one pilot received from the at least one interfering base station. The terminal may send information indicative of the estimated channel quality to the serving base station. The serving base station may send a data transmission on the at least one resource to the terminal.
