  • Patent number: 9832664
    Abstract: An apparatus for receiving reverse link signals from a plurality of subscriber units in a multi-path environment is described. The apparatus includes a receiver in a base station that receives a first plurality of reverse link signals and a second plurality of reverse link signals in a time interval. Each reverse link signal of the first plurality of reverse link signals is derived from at least a common pseudo noise (PN) sequence and unique orthogonal sequence and each reverse link signal of the second plurality of reverse link signals is derived from a unique pseudo noise (PN) sequence. The apparatus also includes a a processor that determines a timing offset associated with at least one reverse link signal to align a timing of the at least one reverse link signal with reverse link signals from other subscriber units.

  • Patent number: 9781626
    Abstract: A system and method are provided for allocating wireless channels in a base station processor to messages sent between a subscriber and the base station processor in a wireless network. A latency period is determined corresponding to a return message to be received from a responsive node in response to an outgoing message sent from a sender via the base station processor. A latency manager in the base station processor computes the latency period and stores the latency period in an allocation table. A scheduler schedules a channel to be available at the end of the latency period indicated in the allocation table. At the end of the latency period, the return message is received and the scheduler allocates a channel as defined in the allocation table. The scheduled channel is used to transmit the message to or from the corresponding subscriber.

  • Publication number: 20170215150
    Abstract: In a wireless communication system, there are several wireless channels used for communication between users and a base station. Channel characteristics may be defined by whether a channel is carrying traffic data and the timing of the channel transmissions with respect to channels not carrying traffic data. Different power levels between channels carrying traffic data or not may be defined and individual power levels of each channel may be amended based on individual power level command responses.

  • Patent number: 9686713
    Abstract: A packet data system such as a TCP/IP network transmits packets containing a variety of data types along links in the network. Packets are transmitted in a stream between nodes interconnected by the links connections, which conform to a transport layer protocol such as TCP, UDP, and RSTP, and include wireless links, which transmit packets using a radio frequency (RF) medium. By examining the data in a packet, performance characteristics such as a port number are determined. The performance characteristics indicate the application type, and therefore, the data type, of the packets carried on the connection. Since certain data types, such as streaming audio and video, are more loss tolerant, determination of the data type is used to compute link control parameters for the wireless link which that are optimal to the type of data being transmitted over the link.

  • Publication number: 20170156139
    Abstract: A control channel supporting traffic control in epochs is divided into two control subchannels each being less than or equal to about a half epoch in duration and occurring serially in time. Slot allocation data may be transmitted and received independently over the subchannels. One subchannel may be used for transmitting forward slot allocation data and the other subchannel may be used for transmitting reverse slot allocation data. The channel split into two subchannels may be a paging channel. The forward and reverse slot allocation data may be transmitted between a base station processor and field unit. Forward and reverse traffic data may be staggered by at least about half an epoch. Transmission of traffic data happens within about two epochs after the assignments.

  • Patent number: 9661583
    Abstract: In an illustrative embodiment of the present invention, a reference signal including pilot information is transmitted from a base station to one or multiple field units over a pilot channel. A message is also sent to the field units over a paging channel to indicate an effective radiated power level at which the reference signal is transmitted on the pilot channel. Based on a received power level of the reference signal at a field unit and the effective radiated power level of the reference signal, a forward path loss is estimated at the field unit for the forward link between the base station and field unit. Assuming the path loss in the reverse link is approximately the same as the estimated forward link path loss, the field unit can transmit, a reply message in the reverse link so that the base station generally receives a message at-a desired power level.

  • Publication number: 20170142714
    Abstract: A downlink communication is transmitted/received in at least one downlink time slot. In response to the received downlink communication, an acknowledgement message is received/transmitted in an uplink time slot a fixed integer number of uplink time slots after transmission/reception of the received downlink communication.

  • Publication number: 20160366630
    Abstract: Method and apparatus for base stations and subscriber units may allow for soft handoff of a CDMA reverse link utilizing an orthogonal channel structure. Subscriber units may transmit an orthogonally coded signal over a reverse link to the base stations. A given base station provides timing control of the timing offset of the reverse link signal. The timing offset may be an absolute timing offset or a differential timing offset. The absolute timing offset may be signaled using more bits than the differential timing offset. Subscriber units may receive power control commands from one or more base stations.

  • Publication number: 20160353508
    Abstract: A technique for communication with a local area network (LAN) via a wireless connection determines whether a first short-range, high-speed, wireless communication path is available and connects to the LAN using a longer range, lower speed wireless communication path if the short-range, high-speed wireless communication path is not available. The low-range, high-speed wireless communication path is a wireless communication path is a wireless LAN connection such as an IEE 802.11-compliant wireless LAN and the long-range, low-sped wireless communication mode is a cellular CDMA-type connection. Determining whether the first IEEE 802.11 mode is available can be done by detecting a beacon signal, or transmitting a probe request message and detecting a probe response message in response to the probe request, indicating the presence or availability of the short-range, high-speed wireless communication path.
