  • Patent number: 11153875
    Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 11153815
    Abstract: in the context of “operator-controlled Wi-Fi” as in 3GPP TR 37,834 v12,0,0 “Study on Wireless Local Area Network (WLAN)”, both in solution2 and solution3, WLAN identifiers need to be communicated between the radio access network, RAN, and the UE. However, WLAN identifiers (e. g., SSIDs, BSSIDs, ESSIDs, HESSIDs, Realm identifiers, NAIs, PLMN identifiers, Domain Name lists, . . . ) are large (e. g., SSID may be up to 32 bytes) and cause a large overhead in the wireless interface. This problem is solved by providing an indexed listing of WLAN Identifiers and by only exchanging the indices across the wireless interface; Preferably, some WLANs may have several indices, and each index may also be used to convey the action to take by the UE.

  • Patent number: 11134403
    Abstract: An interface circuit in an electronic device may provide rate feedback. During operation the interface circuit may transmit one or more packets or frames associated with a data stream that are intended for the recipient electronic device, where the data stream is associated with a video encoder. Then, the interface circuit may estimate a communication performance metric associated with at least the transmissions. For example, the estimated communication performance metric comprises an effective capacity associated with a wireless link between the electronic device and the recipient electronic device. Moreover, the effective capacity may be estimated based at least in part on an efficiency of the wireless link. Next, the interface circuit may provide the rate feedback intended for the video encoder based at least in part on the estimated communication performance metric. In some embodiments, when beamforming occurs, the rate feedback may be reset.

  • Patent number: 11089588
    Abstract: A radio communication system includes a first base station that manages a first cell (110), a second base station (12) that manages a second cell (120), and a radio terminal (2). The radio terminal (2) supports dual connectivity involving a bearer split in which a first network bearer between the radio terminal (2) and a core network (3) is split over the first base station (11) and the second base station (12). The first base station (11) receives, from the second base station (12), bearer split status information about communication of the first network bearer in the second base station (12), and performs control of an access stratum related to the first network bearer. It is thus possible to contribute, for example, to an improvement in control of an access stratum when dual connectivity involving a bearer split is performed.

  • Patent number: 11083017
    Abstract: According to some embodiments, a method for use in a user equipment (UE) of managing a listen-before-talk (LBT) contention window size comprises receiving scheduling for a current burst of contiguous uplink subframes. For each subframe the scheduling comprises an associated hybrid automatic repeat request (HARQ) process identifier and a new data indicator (NDI). The method determines a reference subframe based on a previously-scheduled burst of contiguous uplink subframes. The reference subframe is associated with a reference HARQ process identifier. When the UE determines the HARQ process identifier associated with a subframe of the current scheduled burst of contiguous uplink subframes matches the reference HARQ process identifier and the NDI indicates new data, the method resets the LBT contention window. When the reference HARQ process identifier matches, but the associated NDI indicates a retransmission, or the HARQ process identifier does not match, the method increments the LBT contention window.
