  • Patent number: 9467268
    Abstract: An apparatus and method are provided for feeding back channel quality information and performing scheduling using the fed-back channel quality information in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). In the OFDMA wireless communication system, forward performance degradation due to a decrease in an amount of reverse channel quality information is reduced, and also an increase in the reverse load due to channel quality information feedback is suppressed. A base station controls power of a physical channel using information fed back from a mobile station. In a method for feeding back channel quality information from the mobile station, sub-band-by-sub-band channel quality information is measured and channel-by-channel quality information of a number of channels is transmitted in order of sub-bands of better channel quality information. Average channel quality information for a total band is measured and transmitted.

  • Patent number: 9444587
    Abstract: Techniques for relaying transmissions in a wireless communication network are described. In one design, a relay may receive at least one assignment for a packet, which may be sent to the relay or intercepted by the relay. The relay may receive at least one transmission of a packet sent from a transmitter to a receiver. The relay may process the at least one transmission to decode the packet and may generate at least one additional transmission of the packet after correctly decoding the packet. The relay may send the at least one additional transmission of the packet to the receiver. The transmission(s) and the additional transmission(s) may be HARQ transmissions with different redundancy information for the packet. The transmitter may send transmissions until an acknowledgement (ACK) is received from the receiver or the relay. The relay may send additional transmissions until an ACK is received from the receiver.

  • Patent number: 9391850
    Abstract: The disclosed method and apparatus provides systems, methods, and apparatuses for implementing a PQoS flow between two or more nodes located in different network segments of a multi-segment network, when some nodes involved in the flow lack support for high layer QoS management protocols. Specifically, some embodiments are directed toward implementing a PQoS flow involving some nodes that lack network layers higher than a Data Link Layer (layer 2). For example, some embodiments of the current disclosed method and apparatus can create a parameterized QoS flow between a source node and a destination node when at least one of the nodes participating in the flow (i.e. the source node, one or multiple bridge nodes that the QoS flow passes, and the destination node) lacks UPnP QoS Device Services (i.e., a higher layer QoS management protocol).

  • Patent number: 9374749
    Abstract: Certain embodiments of the present disclosure provide a method for switching radio frequency (RF) carriers that serve communication between a base station (BS) and a mobile station (MS). The switching of carriers can be viewed as a handoff procedure between two different RF carriers within the same BS. A simplified handoff procedure for switching of RF carriers can be applied when the MS switches its physical connection from a primary RF carrier to a secondary RF carrier, as well as in the case when the BS decides to move the MS from one primary RF carrier to another primary RF carrier.
