Network initiated re-authorization for coverage enhancement It is provided a method, comprising checking if a device is authorized for initiating an access in an extended coverage; inhibiting the device to initiate the access while the device camps in the extended coverage and the device is not authorized for the initiating of the access in the extended coverage; monitoring if a paging message for the device is received while the device camps in the extended coverage, wherein the paging message is to initiate a signaling access in the extended coverage for a signaling procedure to get the latest status of coverage authorization; allowing the device to initiate the signaling access while the device camps in the extended coverage if the paging message is received.

According to some embodiments, a method performed by a network node for updating system information (SI) in unlicensed spectrum includes determining to perform a SI update at a SI modification time, and for each SI update period of a plurality of SI update periods remaining before the SI modification time, transmitting a SI update notification to a wireless device. The SI update notification includes an indication of a SI modification time for when the UE should acquire updated SI. In some embodiments, the method further includes determining that the SI modification time has passed and that the SI update notification was not sent successfully for at least one SI update period of the plurality of SI update periods and transmitting a SI update notification to a wireless device including an indication that the wireless device should acquire updated SI immediately.

Methods for uplink feedback information transmission, a terminal device, and a network device. A method includes the following. A terminal device receives first downlink data and second downlink data, where a first ACK/NACK resource corresponding to first ACK/NACK information of the first downlink data and a second ACK/NACK resource corresponding to second ACK/NACK information of the second downlink data occupy the same time-domain resource. The terminal device transmits the first ACK/NACK information and/or the second ACK/NACK information on the time-domain resource.

An integrated circuit includes a first through fourth devices positioned over a substrate, the first device including first through third transceivers, the second device including a fourth transceiver, the third device including a fifth transceiver, and the fourth device including a sixth transceiver. A first radio frequency interconnect (RFI) includes the first transceiver coupled to the fourth transceiver through a first guided transmission medium, a second RFI includes the second transceiver coupled to the fifth transceiver through a second guided transmission medium, and a third RFI includes the third transceiver coupled to the sixth transceiver by the second guided transmission medium.

An information transmission method, a base station and a network management entity are provided. The information transmission method includes: transmitting and/or receiving, by the base station, a reference signal in accordance with a configuration of reference frame structure, and/or determining, by the base station, an uplink and/or downlink time-domain transmission resource configuration in accordance with the configuration of reference frame structure. The uplink and/or downlink time-domain transmission resource configuration is used when the base station communicates with a UE served by the base station, and the configuration of reference frame structure includes a period of a reference frame, and at least one of a first reference point and a second reference point in the period of the reference frame.

Data transmission methods and devices are provided. A data sender determines a target sending position based on channel detection results of available sending positions within a set time window. The length of the set time window is associated with a type of data to be transmitted. The data to be transmitted includes signaling or a signal that is periodically sent. The length of the set time window does not exceed a transmission period of the data to be transmitted. The data sender may further transmit the data at the target sending position.

Systems, and method and computer readable media that store instructions for slowing or stopping a progress, towards a target, of a drone controlled by a remote control unit.

The disclosure relates to a communication technique for convergence of a 5.sup.th Generation (5G) communication system for supporting a higher data transmission rate beyond a 4.sup.th Generation (4G) system with an IoT technology, and a system therefor. The disclosure may be applied to intelligent services based on a 5G communication technology and an IoT-related technology. A method of a terminal in a wireless communication system is provided. The method includes receiving, from a base station, physical uplink control channel (PUCCH) configuration information including a number of slots for repetition of a PUCCH transmission and a length of a subslot for a PUCCH, receiving, from the base station, downlink control information (DCI), receiving, from the base station, data on a physical downlink shared channel (PDSCH) based on the DCI, and transmitting uplink control information (UCI) on the PUCCH repeatedly based on the number of slots and the length of the subslot.

A method and an apparatus for configuring transmission time interval (TTI), including a processor configured to execute instructions to: transmit to a user equipment (UE) configuration information about data radio bearers (DRBs), the configuration information about DRBs indicating TTI length to which each DRB configured by the eNB for the UE is applicable, wherein the DRBs are configured by radio resource control (RRC), and notify a target eNB of the TTI length to which each DRB of the UE is applicable when the UE needs to be handed over.

Certain aspects of the present disclosure provide techniques for indicating capability of a user equipment (UE) to support multiple sounding reference signals (SRSs) with a single subframe, with at least one of frequency hopping, different bandwidths, or antenna switching for the multiple SRSs in the same subframe.
