  • Patent number: 11849421
    Abstract: Methods, systems, and devices for wireless communications are described. Some user equipment (UE) may be equipped with multiple subscriber identity modules (SIMs). A multi-SIM UE may receive a control message at a first SIM which indicates a set of sounding reference signal (SRS) resources for receiving SRS according to a first periodicity. The UE may also receive a registration message at a second SIM which includes a first parameter indicating a first set of paging occasions for receiving paging messages in accordance with a second periodicity. The UE may identify a collision in time between the one or more SRS resources and paging resources, and may transmit a registration request message to a base station. The UE may then receive a second registration message which includes a second parameter for calculating a second set of paging occasions that have a third periodicity that are non-overlapping with the SRS resources.

    Abstract: The present invention herein provides apparatus and method, allowing a user to acquire a target location wherever the target is with a target mobile locator. The target mobile locator includes a RF receiver, a transmitter, a GPS locator and a circuit. After receiving “wake-up” signal from the user, GPS locator and/or transmitter can be activated and the target location is sent back to the user. Prior to receiving the wakeup signal, at least one of the GPS locator and the transmitter are either energy reduced state or off state such that the consumption of the energy is minimized in the locator. Therefore, the locator is active for long periods of time. Optionally, a battery can be recharged using, for example, a solar cell under the sun.

  • Patent number: 10749737
    Abstract: Disclosed is an interoperability gateway system that provides backup connection between a dispatch center and a Land Mobile Radio (LMR) system in the event the dispatch center is disconnected from the LMR system. In general, this may be accomplished by providing an RF link between the disconnected site and the interoperability gateway via a controller, or interoperability site network interface (ISNI), that is activated when the dispatch center is disconnected from the LMR system. The interoperability gateway provides the backup connection by allocating a control station for each channel available at the disconnected LMR system. When compared to conventional dispatch console backup schemes, the disclosed interoperability gateway system greatly reduces the equipment needed to provide dispatch console backup, thereby decreasing equipment and operation costs, and simplifying operation by providing a solution that is virtually transparent to the dispatcher.

    Abstract: Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters. The transmitter then stores these communication parameters and when transmitting to that particular receiver, the transmitter utilizes the stored parameters in an effort to maximize the data rate to that receiver. Likewise, when the receiver receives packets from that particular transmitter, the receiver can utilize the stored communication parameters for reception.

The method for communicating with a relay station comprises transmitting resource allocation information of downlink traffic and uplink traffic from a base station to the relay; and transmitting the downlink traffic to the relay by encapsulating the downlink traffic in accordance with the resource allocation information and receiving encapsulated uplink traffic from the relay in accordance with the resource allocation information. It is possible to enable efficient communication through a relay using a minimum interface without deterioration of throughput even in the case that a base station does not know detailed attributes of a relay existing in a system. Also, it is possible to coordinate collision through a master relay in case of a system supporting multi-hop relays.

  • Publication number: 20140162548
    Abstract: The objective of the present invention is to provide a relay apparatus capable of performing normal relay transmission for broadcast waves by preventing effects caused by wraparound in a relay apparatus. For broadcast waves received by a relay apparatus (2), the same broadcast data are placed in each of a defined segment (f0) and a first segment (f1) other than the defined segment, whereupon the relay apparatus removes broadcast data for the defined segment (f0) from the received broadcast waves, and transmits broadcast waves in which the broadcast data for the first segment (f1) have been exchanged with each of the defined segment (f0) and a second segment (f2) other than the defined segment and the first segment. As a result, the defined segment (f0) which imparts wraparound effects to the received broadcast waves is removed, and therefore, it is possible to perform normal relay transmission of the broadcast waves.

  • Patent number: 8743769
    Abstract: Disclosed is a radio communication device capable of improving the usage efficiency of resources in multi-stage relay to reduce the amount of delay of a relay signal and improving the reception quality of signals by a relay station or a base station. A transmission determining unit 16 determines whether to transmit the relay signal and whether to transmit ACK/NACK on the basis of whether there is an error in the relay signal, and on the basis of ACK/NACK received from a one-hop-downstream radio communication device. An MCS determining unit 17 provided in the transmission determining unit 16 determines an MCS for the relay signal. A transmission instruction generated by the transmission determining unit 16 is output to a buffer 11 and an ACK/NACK generating unit 19. The determined MCS is output to an error correction coding unit 12 and a modulation unit 13. The ACK/NACK generating unit 19 generates ACK when there is no error in the relay signal, and generates NACK when there is an error in the relay signal.

  • Patent number: 8681685
    Abstract: According to a detailed embodiment of the invention, the RS implements the following operations by using each of M shift parameter groups: Based on M shift parameters in the group, shifting respectively M decoded bit streams and merge the M shifted bit steams to get a check bit stream. Consequently M check bit streams are obtained by using M shift parameter groups. Then the RS transmits M check bit streams to the BS. The BS has received the M uplink signals from mobile terminals before and makes the M check bit streams as the check information of those uplink signals in order to check them better and reduce error rate. By adopting the method and device proposed by the invention, it is ensured in the low SNR regime error user rate or error block rate is more ideal in multi-user detection in the BS.
