In one aspect, a wireless device receives a scheduling grant and a grant confirmation signal indicating that a network node has performed a CCA on a carrier and is releasing the carrier for the wireless device. An uplink message is transmitted on the carrier without performing a CCA on the carrier. In another aspect, a wireless device is connected to a first cell and a second cell configured on a carrier requiring an LBT protocol. The wireless device receives configuration messages indicating that downlink transmissions on the second cell are to be scheduled. This can mean self-scheduling for downlink on the second cell and cross-carrier scheduling for uplink on the first cell. The wireless device receives a scheduling grant in the first cell and performs a CCA in the second cell. The wireless device then transmits an uplink message responsive to success of the CCA.

Scheduling in license assisted access

According to certain embodiments, a method by a wireless device is provided for transmitting uplink control information (UCI) on a serving cell on the unlicensed spectrum. The method includes formatting the UCI as a shortened control signalling transmission and transmitting the UCI formatted as the shortened control signalling transmission to a network node. The shortened control signalling transmission is transmitted during a transmission opportunity on the serving cell on the unlicensed spectrum without performing channel sensing.

Systems and methods for uplink control information signaling design

A method for use in a User Equipment configured to operate according to the New Radio (5G) standard, said method comprising: monitoring a control region for mini-slots for a transmission; detecting a start of the transmission; monitoring a control region of said transmission for regular slots; detecting that the transmission has ended; and in response thereto monitoring the control region for mini-slots again.

Control channel monitoring

Methods of operation of a wireless device are provided. In particular, Media Access Control (MAC) protocol aspects are disclosed relating to Licensed Assisted Access (LAA) cells and, more generally, to cells of a cellular communications network operating in an unlicensed frequency spectrum. According to one aspect, a method of operation of a wireless device comprises transmitting an Uplink (UL) transmission on a cell for a corresponding UL Hybrid Automatic Repeat Request (HARQ) process, the cell operating in an unlicensed frequency spectrum, and setting a locally maintained status for the UL HARQ process to Acknowledgement (ACK) based on an assumption that the UL transmission was successful.

Uplink MAC protocol aspects

A method for operating a network node of a wireless communication network is disclosed. The method comprises determining and/or adjusting a HARQ signaling format for a terminal configured for carrier aggregation based on a number of DL carriers and/or a number of HARQ bits configured for the terminal.

Implementation of HARQ on PUSCH for multiple carriers

Disclosed are a method and apparatus for transmitting an initial access signal, thus solving the existing problem wherein transmitting and detecting of synchronization signals cannot be applied to large-scale network coverage of a future communication system. The method comprises: determining at least one to-be-transmitted identification information of a synchronization block, the synchronization block comprising at least two components for transmitting an initial access signal, and different components occupying different time-frequency resources of the synchronization block; determining an initial access signal transmitted by each component in the synchronization block according to the identification information; and determining a time-frequency resource occupied by each component in the synchronization block and transmitting the initial access signal of the component on the time-frequency resource occupied by each component.

An embodiment of an adaptive video encoder may include technology to determine headset-related information including at least one of focus-related information and motion-related information, and determine one or more video encode parameters based on the headset-related information. Other embodiments are disclosed and claimed.

Adaptive foveated encoder and global motion predictor

A method of operating a wireless communication device comprises identifying a first start position for performing uplink (UL) transmission in unlicensed spectrum during a first transmission time interval, performing UL transmission in the first transmission time interval (TTI) according to the first start position, identifying a second start position for performing UL transmission in unlicensed spectrum during a second TTI, wherein the first and second start positions correspond to different symbol offsets within the respective first and second TTIs, and performing UL transmission in the second TTI according to the second start position.

Multiple starting and ending positions for scheduled or autonomous uplink transmission in unlicensed spectrum

Systems and methods are disclosed herein that relate to multiple candidate starting points for a transmit burst in unlicensed spectrum. In some embodiments, a method of operation of a radio access node for performing a transmit burst in an unlicensed spectrum comprises transmitting a transmit burst in an unlicensed spectrum, wherein the transmit burst spans multiple subframes/slots and the transmitting of the transmit burst starts at one of a plurality of candidate starting points defined in at least a first subframe/slot of the transmit burst that occurs after successful completion of a Listen-Before-Talk (LBT) procedure for the transmit burst. In this manner, a radio access node (e.g., an enhanced or evolved Node B (eNB) in Long Term Evolution (LTE)) has flexibility to transmit a downlink transmit burst starting at different starting positions based on LBT outcome.

Multiple starting and ending positions for scheduled downlink transmission on unlicensed spectrum

Channel state determination is performed at a user equipment (UE) of a mobile network. The UE determines one or a plurality of time intervals that may be used for channel measurements, performs a plurality of signal power measurements associated each to one of the time intervals to be used for channel measurement and generates a channel state information as a function of the plurality of the signal power measurements. Information comprising an indication of a plurality of time intervals that may be used for received signal power measurements is generated and sent from an access node (eNB) to the UE. The eNB evaluates a measurement report, received from the UE, that comprises received signal power measurements associated each to one of the time intervals.

Methods, user equipment and network node for performing channel state measurements
