  • Patent number: 8848729
    Abstract: The present invention discloses a method for configuring a Physical Downlink Control Channel (PDCCH), a base station and a UE, wherein the base station configures a component carrier or component carriers for monitoring the PDCCH for the UE and notifies the UE about information on the configured component carrier or component carriers so that the UE monitors the PDCCH only over the configured component carrier or component carriers. Stated otherwise, in this way, the UE will operate only over a necessary component carrier or component carriers without monitoring respective component carriers in an LTE-A system to thereby reduce the number of concurrently monitored component carriers, and in the case of nonconsecutive component carriers, also reduce the number of consequently enabled receivers and consequently the amount of consumed power of the UE for monitoring the PDCCH.

The factorisation involves a combined variable representing possible transmitted symbols and CPM states of each user for each symbol time interval, so as to make the iterative process convergent. Non exponential complexity is enabled by disregarding multiple access interference (MAI) from at least some of the other users.

  • Patent number: 8792369
    Abstract: The invention concerns a method and an apparatus implementing the method. In the method is determined in a mobile node whether the mobile node supports mobile node specific cyclic prefixes. The mobile node transmits to a base station node an indication whether the mobile node supports mobile node specific cyclic prefixes. The base station node measures a delay spread of a radio resource transmitted by the mobile node. The mobile node receives an indication of an uplink direction cyclic prefix length from the base station node. The mobile node forms a cyclic prefix of the uplink direction cyclic prefix length selected from a useful symbol, adds the cyclic prefix in front of the useful symbol and transmits a signal comprising the cyclic prefix and the useful symbol to the base station.

  • Patent number: 8787187
    Abstract: A communication device transmits a plurality of measurement packets for identifying an available bandwidth to another communication device connected via a network, using bandwidths in the measurement bandwidth range. The communication device then determines whether the available bandwidth is included in the measurement bandwidth range. In a case where the available bandwidth is not included in the measurement bandwidth range, the communication device determines whether the available bandwidth is located on a narrowband side or on a wideband side with respect to the measurement bandwidth range, and determines a bandwidth shift amount based on an amount of change. The communication device updates the measurement bandwidth range by shifting one of the lower bandwidth and the upper bandwidth based on the bandwidth shift amount.

  • Patent number: 8787291
    Abstract: A wireless communication base station apparatus wherein when a frequency scheduling transmission and a frequency diversity transmission are performed in a multicarrier communication at the same time, the adaptive control of a channel for performing the frequency scheduling transmission can be prevented from being complicated. In this apparatus, a modulating part modulates an encoded Dch data to generate Dch data symbols. A modulating part modulates an encoded Lch data to generate Lch data symbols. An assigning part assigns the Dch and Lch data symbols to subcarriers constituting OFDM symbols and outputs them to a multiplexing part. At this moment, the assigning part assigns a set of Dch and Lch data symbols to each subcarrier for a respective subband.

  • Patent number: 8780876
    Abstract: Briefly, in accordance with one or more embodiments, user equipment receives unicast services from a first carrier of a primary serving cell and determines if Multimedia Broadcast and Multicast services (MBMS) services are available on a second carrier based at least in part on information in a broadcast carrier channel that indicates the second carrier or an identification (ID) of the second carrier. If MBMS services are available on the second carrier, the user equipment at least temporarily switches to the second carrier to receive the MBMS services. The user equipment may provide feedback to the network or the primary serving cell when it starts and stops receiving MBMS services, and then may switch back to the primary serving cell when MBMS services have ended or the user equipment no longer desires to receive MBMS services.

  • Patent number: 8774067
    Abstract: There are first and second antennas proximally disposed and configured to resonate within respective first and second frequency bands, which may overlap. An impedance stabilization circuitry is coupled to ground. There is a selective coupler (for example, diplexer, directional coupler, switch) interfacing the second antenna selectively with the impedance stabilization circuitry and with radio circuitry. The selective coupler comprises a first port coupled to the second antenna, a second port coupled to the impedance stabilization circuitry, and a third port configured to couple with radio circuitry that is configured to operate in the second frequency band. The selective coupler provides a predetermined impedance to signals within the first frequency band and a low insertion loss to signals within the second frequency band, thus providing a stable impedance for the first antenna's view of the second antenna.
