    Abstract: This disclosure relates to carrier aggregation using separate RLC entities for different component carriers. According to one embodiment, a base station and a wireless device may establish a primary component carrier and at least one secondary component carrier according to a first radio access technology. Separate radio link control entities may be established for the primary component carrier and the secondary component carrier. Data communicated between the base station and the wireless device may be routed by way of the primary component or the secondary component carrier based on differing characteristics of the component carriers, and the RLC entities may treat downlink data differently on the primary component carrier and the secondary component carrier based on the differing characteristics of the component carriers.

    Abstract: A device and method generates a hopping scheme for mobile stations of a wireless network. The method includes receiving a number of channels N of the wireless network. The method includes generating a shuffling matrix as a function of the number of channels N, each row of the shuffling matrix being indicative of a respective one of the mobile stations, each column of the shuffling matrix being indicative of a respective broadcast time of a discovery signal in a hopping scheme. The method includes generating the hopping scheme for the mobile stations in the channels as a function of the shuffling matrix. The hopping scheme maximizes an interval between two consecutive broadcast times that any two of the mobile stations are assigned to transmit discovery signals on adjacent channels.

    Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: receiving first signaling information from a first base station (BS), where the first signaling information indicates that a user equipment (UE) device is to determine an index of a first synchronization signal block (SSB) transmitted by a second BS to the UE device on a second component carrier, based on timing information regarding a first component carrier associated with the first BS; determining a first measurement window for measuring one or more characteristics of the first SSB, where the first measurement window is determined based on a first time offset value Δt1 and an expected length of the first SSB and measuring the one or more characteristics of the first SSB on the second carrier during the first measurement window.

    Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to select N≥2 radio frequency carriers for UL transmission from M>N available radio frequency carriers and subsequently send UL transmissions to a cellular wireless network based on the configuration. The M available radio frequency carriers are divided into distinct TAGs, each TAG having a distinct timing advance value, and the N radio frequency carriers belong to a single TAG. The wireless device is further configured to switch to a second set of N UL radio frequency carriers, after an uplink switching gap time period, based on a TAG medium access control (MAC) control element (CE), received the cellular wireless network, which specifies a second TAG from which to select the second set of N UL radio frequency carriers.

    Abstract: A network may transmit either beam deployment information or beam number information to a user equipment (UE) carried on a train and configured for operation in the millimeter wave band. The deployment information may include deployment related distance parameters or azimuth angle spread parameters. The beam number information may indicate a number of network beams associated with a current cell. The UE may determine a number of UE receive beams based on deployment information or the network-indicated number of network beams. The UE may transmit feedback to the network, indicating the number of UE receive beams. Alternatively, the network may send a configuration message indicating a first number of UE receive beams to the UE, which the UE may treat as an upper bound or lower bound in its determination of a desired number of UE receive beams. The UE may transmit the desired number to the network.

    Abstract: This disclosure relates to techniques for a wireless device to initiate channel occupancy in unlicensed spectrum in a wireless communication system. The wireless device may establish a wireless link with a cellular base station. The wireless device may determine to perform an uplink transmission to the cellular base station on an unlicensed frequency channel. The wireless device may determine whether the cellular base station has channel occupancy of the unlicensed frequency channel. The wireless device may determine whether to initiate channel occupancy of the unlicensed frequency channel. The decision whether to initiate channel occupancy may be based at least in part on whether the cellular base station has channel occupancy of the unlicensed frequency channel.
