Abstract: A base station (300), a wireless device (302) and methods thereinfor supporting radio communication, wherein the base station (300) employs carrier aggregation with multiple carriers serving a primary cell, PCell, and at least one secondary cell, SCell. The base station (300) signals (3:3) an SCell status to the wireless device (302), the SCell status indicating whether the at least one SCell will be in active state where the base station (300) transmits downlink signals on a carrier serving the at least one SCell, or in inactive state where the base station (300) does not transmit downlink signals on the carrier serving the at least one SCell. Thereby, the wireless device (302) can adapt its behaviour depending on the signalled SCell status, e.g. by turning off its receiver and not perform any signal measurements when the SCell is in inactive state.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently facilitating acknowledgment (ACK) or negative acknowledgment (NACK) feedback from a user equipment (UE) for a set of transport blocks in one or more multicast transmissions from a base station. The UE may determine control channel resources for transmitting the ACK/NACK feedback, and each respective control channel resource may correspond to a distinct subset of the set of transport blocks. Once the UE determines a subset of transport blocks that the UE failed to decode (such as at least one transport block), the UE may determine a respective control channel resource that corresponds to the at least one transport block that the UE failed to decode. The UE may transmit ACK/NACK feedback on the respective control channel resource, which, in some examples, may indicate that the UE failed to decode the subset of transport blocks.

The feedback report includes an identification of the second UE in the wireless network and a measurement result of the sidelink connection from the second UE.

Abstract: The present disclosure relates to a communication scheme and system for converging a 5th generation (5G) communication system and a 4th generation (4G) system. A UE performs a random access on a supplementary uplink (SUL) frequency, and transmits a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) on the SUL frequency. A Next Generation NodeB (gNB) determines to use a New Radio (NR) uplink (UL) frequency for PUSCH transmissions, and transmits PUSCH configuration information for the NR UL to the UE. The UE transmits a PUSCH on the NR UL but still transmits the PUCCH on the SUL frequency.

Abstract: Aspects of the technology described herein are directed towards using generic control information in a three-party wireless communication system to schedule a data transmission and reception of the data transmission. A scheduler node transmits the generic control information, comprising identification information that identifies a user equipment device as a transmitter node, and scheduling information that schedules a data transmission. For unicast data transmissions, the generic control information further identifies a receiver node, and can schedule transmission of an ACK/NACK from the receiver node corresponding to receiving the data transmission. A control procedure can be configured in a user equipment device by linking a channel configuration dataset to a resource configuration dataset, which in turn is linked to a channel transmit and receive configuration dataset. Reconfiguration is achieved by changing the linking(s) between one or more different available datasets.

Abstract: A method for managing a managed forwarding element (MFE) that forwards data in a network. A network controller publishes, to the MFE, a first set of data for configuring the MFE to perform a set of forwarding operations. The network controller collects, from the MFE, a second set of data regarding current operational state of the MFE. The network controller identifies a difference between a desired operational state of the MFE maintained by the network controller and the collected current operational state of the MFE. Based on the identified difference, the network controller publishes a new third set of data for configuring the MFE to adjust the current operational state of the MFE to the desired state.

Abstract: Systems and methods for aligning timing of an inroute transmission of a terminal with a gateway are disclosed. A system may include a processor and a memory storing instructions, which when executed by the processor, may cause the processor to perform a random estimation of location pertaining to a time-division multiple access (TDMA) frame boundary of a gateway.

The system may receive a feedback from the gateway, in response to the precise timing feedback request. The processor may determine an adjustment for aligning timing of an inroute transmission of the terminal with respect to the TDMA frame boundary of the gateway. The system may apply the adjustment to synchronize the timing of the inroute transmission of the terminal with the gateway.
