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.

Techniques for providing efficient transmit diversity and bandwidth segmentation in a wireless communication system

Devices, systems and techniques to monitor signal fading based on a cluster of subcarriers at a receiver and feedback monitored signal fading to a transmitter in wireless communication systems such as OFDM and OFDMA systems.

Subcarrier cluster-based power control in wireless communications

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.

Efficient acknowledgement messaging in wireless communications

Efficient uplink feedback mechanisms from subscriber stations to a base station involved in a multicast/broadcast service (MBS) to report channel conditions at the subscriber stations to the base stations in order to select a suitable burst profile in transmitting MBS data by the base station in OFDM and OFDMA wireless communication systems.

Feedback mechanisms for multicast/broadcast service in wireless communication networks

Methods and systems for implementing trunking techniques in WCDMA systems for handling group calls and push-to-talk services.

Trunking and push-to-talk mechanisms for WCDMA wireless communications

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.

Methods and systems for implementing trunking techniques in CDMA systems for handling group calls and push-to-talk services.

Trunking system for CDMA wireless communication

Interconnection and integration of a WWAN and a WLAN to provide continuous packet data services to mobile users where each mobile access terminal is configured to support both air links with the WWAN and WLAN. The WWAN may be a CDMA2000 system and the WLAN may be an IEEE 802.11 system.

Interworking mechanism between wireless wide area network and wireless local area network

Efficient hand over mechanisms for OFDM and OFDMA wireless communication systems to operate a mobile subscriber station to transmit and receive a frame with only one base station while monitoring communications with adjacent base stations.

Virtual soft hand over in OFDM and OFDMA wireless communication network

Methods and systems for implementing trunking techniques in CDMA systems for handling group calls and push-to-talk services and roaming of group calls.

Global open trunking system for CDMA wireless communication

Error correction techniques based on a modified chase combining (MCC) in data retransmission in communication systems such as wired and wireless communication systems. The described MCC may be implemented in wireless communication systems that use hybrid automatic repeat request (H-ARQ) in data transmission. In wireless systems, the mobile communications devices and base stations may be designed with the present MCC.
