  • Patent number: 10117234
    Abstract: A system and method for mapping a combined frequency division duplexing (FDD) Time Division Multiplexing (TDM)/Time Division Multiple Access (TDMA) downlink subframe for use with half-duplex and full-duplex terminals in a communication system. Embodiments of the downlink subframe vary Forward Error Correction (FEC) types for a given modulation scheme as well as support the implementation of a smart antenna at a base station in the communication system. Embodiments of the system are also used in a TDD communication system to support the implementation of smart antennae. A scheduling algorithm allows TDM and TDMA portions of a downlink to efficiently co-exist in the same downlink subframe and simultaneously support full and half-duplex terminals.

  • Patent number: 9980284
    Abstract: In a wireless (e.g., machine-to-machine) network, items of user equipment compete for wireless communication resource slots (“resources”). In a contention period, an item of user equipment (a UE) sends a first signal to a base station using a first resource. The first resource is mapped to a second resource in a data transmission period. If the base station successfully receives the first signal, it sends a second signal to the UE to confirm that the UE has been awarded the second resource and can transmit data in the data transmission period.

  • Patent number: 9973959
    Abstract: According to one aspect of the teachings herein, a wireless device operating in a wireless communication network determines the difference in signal arrival times with respect to first and second cells, and the device and/or the involved wireless communication network uses the difference to control one or more aspects of Carrier Aggregation, CA, operation for the wireless device. For example, there may be a maximum timing difference defined for the wireless device, e.g., as a function of its inherent capabilities, and the wireless device may evaluate the timing difference of a second cell that is a candidate of aggregation into its CA configuration, or that may be a candidate for activation as a serving cell within a CA configuration, with respect to a first cell that is already in use as a serving cell for the wireless device.

  • Patent number: 9936503
    Abstract: This disclosure provides a method and for determining WLAN channel in a base station which supports both WLAN access and cellular network access, and a first WLAN channel is allocated for its WLAN access. According to this disclosure, if frequency space between the first WLAN channel and frequency range occupied by the cellular network access is not larger than a threshold, the base station detects available WLAN channels which are not occupied by surrounding WLANs. If the frequency space between the available WLAN channels and the frequency range occupied by the cellular network is not larger than the threshold, the base station changes its WLAN channel from the first WLAN channel to a second WLAN channel occupied by one of the surrounding WLANs. The frequency space between the second WLAN channel and the frequency range occupied by the cellular network access is larger than the threshold, thus interference between the cellular network and the WLAN is reduced or eliminated.

  • Patent number: 9913294
    Abstract: A radio communication system includes a radio base station and a terminal device. The radio base station and the terminal device share correspondence information about subsets of preamble sequences obtained by segmenting preamble sequences available in the radio communication systems into groups, each of the subsets being associated with a received signal level at the terminal device and a number of repetitions for transmitting the preamble sequences of each of the subsets. Based upon a receive level of a signal transmitted from the radio base station, the terminal device selects a subset corresponding to the receive level by referring to the correspondence information and transmits a preamble sequence included in the selected subset at the number of repetitions associated with the selected subset.

  • Patent number: 9893842
    Abstract: A technique of processing an Automatic Repeat Request (ARQ) transmission is disclosed. As to a method aspect of the technique, the method comprises the steps of requesting a retransmission of a transport block; receiving the retransmission of the transport block; and detecting modulation symbols. The retransmission is requested in response to an error-detecting code indicating an error in the transport block as received in at least one previous transmission. The modulation symbols are detected based on at least a part of the received retransmission and information from the at least one previous transmission. At least in some embodiments, a detection rate is thus improved.

  • Patent number: 9876691
    Abstract: Methods, systems, and computer readable media may be operable to facilitate client device band steering based upon deep packet inspection information. An access point may be configured to steer one or more client devices from a low frequency band to a high frequency band, and vice versa, based on the status of the low frequency band and/or high frequency band and the client devices associated with the bands. The access point may perform a deep packet inspection of data packet traffic associated with each associated client device, and may classify each client device as either a device associated with a media session or a device that is not associated with a media session based upon information retrieved from the deep packet inspection. The access point may choose one or more client devices to disassociate from a frequency band based upon the media session classification of the client devices.
