Abstract: A station makes a unidirectional announcement (that is, an indication, notification or advertisement) of types of services that are available to devices in or via a wireless network, for example, a wireless local area network (WLAN). The announcement is receivable by mobile devices within radio communication range of the wireless network that are in the pre-associated state, because the announcement is conveyed using low-level layer 2 frames. A mobile device that receives such a layer 2 frame may determine the announced service type or types from the received layer 2 frame. The mobile device may determine whether it can make use of any of the announced service type or types. The mobile device may provide results of the determination to a network selection algorithm implemented at the mobile device.

Abstract: A technique for providing per station control of multiple stations in a wireless network across multiple access points. A look-up table that assigns a station connected to the access point and at least one communication parameter to each of a plurality of persistent, uniquely-assigned BSSIDs (Basic Service Set Identifiers) is stored. An access point responds to messages addressed one of the plurality of persistent, uniquely-assigned BSSIDs and ignores messages addressed to other BSSIDs. Persistence of the BSSID allows the controller to maintain individual control over each station after moving to a second access point of the plurality of access points. A frame comprising the plurality of BSSIDs corresponding to each connected station aggregated into the frame is generated. The frame is transmitted to the plurality of stations.

The method includes: performing real-time estimation according to time domain information of M downlink transmit signals, to obtain a first intermodulation interference signal; and cancelling, according to the first intermodulation interference signal, intermodulation interference generated by the M downlink transmit signals in an uplink receive signal, where M is an integer greater than or equal to 2, and the M downlink transmit signals are baseband signals that are transmitted on M carriers and that are not combined. Based on the foregoing solutions, the actually generated intermodulation interference can be effectively cancelled, thereby reducing intermodulation interference and improving system performance.

Abstract: A technique for measuring Reference Signal Received Power (RSRP) is provided. The RSRP is measured based on Cell-specific Reference Signals (CRSs) provided by cells (102, 104) of a mobile telecommunications network (100). The CRSs of at least two of the cells overlap in time and frequency. As to a method aspect of the technique, a time offset for sub-frames received from the at least two cells is determined. The overlapping CRSs are received for a group of sub-carriers.

The phase-shifted CRSs of different sub-carriers in the group include a phase-shift that corresponds to the determined time offset. The RSRP is measured for each of the at least two cells based on the estimated coarse channel state.

Abstract: Systems and methods are described for improving capacity of voice services for data packet transmission through a wireless network. Application requirements including a data rate for a wireless device may be determined. An access node may determine available resources to transmit data as indicated by the application requirements.
