Patent number: 8494593Abstract: Devices and methods are provided for providing wireless coverage redundancy in case, for example, the backhaul of an access point (AP) base station is not available. In one embodiment, the method involves monitoring the backhaul, and in response to the backhaul being available, facilitating communication between an access terminal (AT) and the macro network via the backhaul. In addition, or in the alternative (e.g., when the backhaul is not available), a communication signal between the AT and a macro base station (or another AP base station) may be boosted.Type: GrantFiled: January 23, 2009Date of Patent: July 23, 2013Assignee: QUALCOMM IncorporatedInventors: Peter J. Black, Matthew S. Grob

Patent number: 8472322Abstract: Adaptive delay management means and method for allocating resources having different Quality of Service (QoS) requirements. A Forward Link (FL) scheduler prepares transmission instances by treating pending data queues according to a priority class, such as Best Effort (BE) and Expedited Forwarding (EF). Data bits from multiple queues are stuffed into a transmission instance. Various metrics are used to generate a set of candidates for transmission and then select and build a next transmission instance from the set of candidates.Type: GrantFiled: May 5, 2005Date of Patent: June 25, 2013Assignee: QUALCOMM IncorporatedInventors: Peter J. Black, Mehmet I. Gurelli, Mehmet Yavuz, Naga Bhushan

Patent number: 8411594Abstract: A system and method for providing group communication services is disclosed. Each of a plurality of group communication devices converts media, such as video, audio, image and/or data into data packets suitable for transmission over a data network, such as the Internet. The data packets are selectively transmitted through the data network to a communications manager. The communications manager acts as a configurable switch, allowing communications from any communication device to be selectively routed to the plurality of communication devices based on the types of the communication devices and/or the requests received from the corresponding users. The communications manager further allows users of other communication systems and devices to participate in group communications with each other.Type: GrantFiled: September 20, 2002Date of Patent: April 2, 2013Assignee: QUALCOMM IncorporatedInventor: Peter J.

Patent number: 8363697Abstract: Synchronized broadcast transmits a same broadcast content using a same waveform from multiple transmitters. Transmitters each apply a same spreading code for broadcast transmissions. In a spread-spectrum communication system having a time division multiplexed forward link, a synchronized broadcast transmission is inserted into a broadcast slot. One embodiment employs an Orthogonal Frequency Divisional Multiplex (OFDM) waveform for the synchronized broadcast. An OFDM receiver is then used to process the received synchronized broadcast transmission. An alternate embodiment implements a broadcast Pseudo-random Noise (PN) code for use by multiple transmitters. An equalizer is then employed to estimate the synchronized broadcast transmission.Type: GrantFiled: January 20, 2005Date of Patent: January 29, 2013Assignee: Qualcomm IncorporatedInventors: Matthew S. Grob, Peter J. Black, Srikant Jayaraman, Paul E. Jacobs

Patent number: 8351372Abstract: In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.Type: GrantFiled: September 29, 2006Date of Patent: January 8, 2013Assignee: QUALCOMM IncorporatedInventors: Roberto Padovani, Paul E. Bender, Peter J. Black, Matthew S. Grob, Jurg K. Hinderling, Nagabhushana T. Sindhushayana, Charles E. Wheatley, III

Patent number: 8213390Abstract: Upon successful decoding of a first set of slots of a first data packet, an Access Network (AN) can send an acknowledge message (ACK) to an Access Terminal (AT) to indicate that the AN has successfully decoded the data received in the first set of slots of the first data packet. Upon unsuccessful decoding of the first set of slots of the first data packet, the AN can send a negative acknowledge message (NAK) to the AT to indicate that the AN has not successfully decoded the data received in the first set of slots of a first data packet. Based upon receipt of the NAK, the AT can resend the data by sending a second set of slots of the first data packet containing redundant data. Based upon receipt of the ACK, the AT can send a first set of slots of another packet.Type: GrantFiled: October 24, 2002Date of Patent: July 3, 2012Assignee: QUALCOMM IncorporatedInventors: Peter J.

Publication number: 20120026939Abstract: In a transmission scheme wherein multi-slot packet transmissions to a remote station can be terminated by an acknowledgment signal from the remote station, code symbols can be efficiently packed over the multi-slot packet so that the remote station can easily decode the data payload of the multi-slot packet by decoding only a portion of the multi-slot packet. Hence, the remote station can signal for the early termination of the multi-slot packet transmission, which thereby increases the data throughput of the system.Type: ApplicationFiled: January 25, 2011Publication date: February 2, 2012Applicant: QUALCOMM INCORPORATEDInventors: Nagabhushana Sindhushayana, Peter J.
