Abstract: A wireless device receives configuration parameters indicating a linkage between a first search space (SS), of a scheduled cell, and a second SS, of a first bandwidth part (BWP) of a scheduling cell, and that a third SS, of the scheduled cell, is not linked to any SSs of a second BWP of the scheduling cell. In response to the linkage and the first BWP being active, the second SS is monitored for receiving a scheduling indication for the scheduled cell. The wireless device switches from the first BWP to the second BWP as an active BWP of the scheduling cell. In response to the switching and the third SS not being linked to the any SSs of the second BWP, the third SS is monitored for receiving DCI for the scheduled cell. The DCI is received via the third SS and for transmission on the scheduled cell.

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.

Abstract: Aspects are provided which enhance Mode 2 multi-TRP operation by allowing a UE to recover and reconfigure a failed PDCCH beam of a first TRP in a serving cell by using a second TRP which still has a working PDCCH in the same serving cell. If the first TRP undergoes beam failure but the second TRP in the same cell has an operational beam, the UE may send a beam failure indication indicating a new beam for the PDCCH of the first TRP. The base station comprising the second TRP may then reconfigure the PDCCH serving beams of the first TRP based on the beam failure indication. The reliability of a serving cell may thus be increased.

Then, the first node and the second node separately mixes the packets received correctly in the first transmission attempt to generate the shared secret.

Abstract: In one embodiment, an issue analysis service obtains telemetry data from a plurality of devices in a network across a plurality of time intervals. The service detects a failure event in which a device in the network is in a failure state. The service clusters the telemetry data obtained prior to the failure event into rounds according to time intervals in which the telemetry data was collected. Each round corresponds to a particular time interval. The service applies a machine learning-based classifier to each one of the rounds of clustered telemetry data to identify one or more common traits appearing in the telemetry data for each round. The service generates a trait change report indicating a change in the one or more common traits appearing in the telemetry data across the rounds leading up to the failure event.

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.

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.
