Abstract: Technologies that, among other things, provide resource allocation in multi-hop wireless networks with relay stations and can be used to supply information to link data packets with a respective resource allocation.

Abstract: Technologies for wireless communications can include communicating connection information that specifies one or more parameters of a connection between a base station and a wireless device. The connection information can be indicative of one or more of: a station identifier, whether data packets associated with the connection include a cyclic redundancy check, and whether data packets associated with the connection include encrypted information. These technologies can include constructing, based on the connection information, a media access control (MAC) protocol data unit (PDU) that includes a header at a beginning portion of the MAC PDU. The header can include one or more of: a first flag that indicates a header type, a second flag that indicates whether there is a subheader inclusion following the header in the MAC PDU, a flow identifier that, together with the station identifier, identifies the connection, and a length value.

Abstract: Wireless communication techniques for cellular deployment of wireless communication systems with transmitters in each cell to have partially overlapped transmission patterns between two adjacent transmitters. Implementations of the described techniques can provide transmit diversity with intentional partial beam pattern overlays to improve cell sectorization or frequency re-use factor, at the same time, reduce intra-cell and inter-cell interference. Various modulations may be used in the described systems, including FDMA, TDMA, and OFDMA modulation schemes.

Abstract: Techniques for acknowledging message reception in a wireless OFDM/OFDMA system in clue receiving an unsolicited MAC management message at a subscriber station, operating the subscriber station to generate an acknowledgement (ACK) signal when the subscriber station receives the message from a base station, providing a pre-allocated uplink resource for the subscriber station to transmit the ACK signal to the base station without making a request to the base station for sending the ACK signal and sending the ACK signal consisting of a MAC header transmitted at the pre-allocated uplink source.

Abstract: Techniques and system designs are described for providing mobile communication systems with negotiation mechanisms to select data integrity schemes based on quality of service (QoS) schemes to enhance system performance during mobile handover processes. In one aspect, a method for providing data integrity in a wireless communication network includes providing a quality of service (QoS) profile for a service flow for a mobile station to include information of one or more QoS requirements of the service flow and a data integrity indicator to indicate information of data integrity for the service flow during a handover of the mobile station from one base station to another base station; and using the data integrity indicator to assist selection of a data integrity scheme from one or more data integrity schemes available to the service flow during the handover of the mobile station.

Abstract: Techniques and systems for acknowledging management message reception in a wireless communication system can include operating a first radio station to generate a management message that contains a sequence number unique to the management message and to direct the management message to a second radio station; and operating the second radio station, after receiving the management message from the transmitter, to generate and transmit, before decoding the content of the received the management message, an acknowledgement to the transmitter identifying the received manage message by the sequence number unique to the management message.

Abstract: Techniques of selective demodulation of downlink frames using a subscriber description segment or activity descriptor to identify one or more subscriber stations to which at least a portion of data placed in the downlink frame is addressed in wireless communication systems such as frame-based point-to-multipoint wireless communication systems. The described techniques can be used to reduce power consumption at each subscriber station and to elongate the battery time of mobile devices, especially in the bursty Internet data transmission. The subscriber station can use information in the subscriber description segment or activity descriptor to decide whether to turn off receiver power for the remainder of a received downlink frame.

Abstract: Systems and techniques for grouping channels, such as pilots, are described. In one aspect, a method includes receiving transmissions of two or more pilot signals at an access terminal of a wireless communications network that includes an access node, based on characteristics of the transmissions of the two or more pilot signals from the access node to the access terminal, determining whether the two or more pilot signals are suitable for grouping and indicating of the suitability of the two or more pilot signals for grouping by sending a pilot information report for the pilot group to the access node.
