A method and apparatus for operating a satellite system including different satellites that may belong to different types of satellite constellations. In some implementations, the satellite system may include a LEO satellite constellation and one or more non-LEO satellite constellations that can be used to increase the forward link capacity of the LEO satellite constellation, for example, by allowing an LEO satellite to offload at least some of its forward link traffic to one of the non-LEO satellites. The user terminals can dynamically switch forward link communications between a LEO satellite and a non-LEO satellite while maintaining a return link connection with the LEO satellite.

The present disclosure provides a method and a device in a User Equipment (UE) and a base station used for wireless communication. The UE transmits K bit blocks, wherein if the number of idle bits on a first physical layer channel is not less than Q before the K bit blocks are placed on the first physical layer channel, the K bit blocks are transmitted on the first physical layer channel; otherwise, the K bit blocks are transmitted on K physical layer channels respectively; the K physical layer channels belong to K serving cells respectively, or, the K physical layer channels belong to one serving cell and time-domain resources occupied by any two of the K physical layer channels are orthogonal; the K bit blocks together are used for determining first information.

An integrated circuit such as, for example a graphics processing unit (GPU), having an on-chip analog to digital converter (ADC) for use in overcurrent protection of the chip is described, where the overcurrent protection response times are substantially faster than techniques with external ADC. A system-on-chip (SoC) includes the integrated circuit and a multiplexer arranged externally to the chip having the ADC, where the multiplexer provides the ADC with a data stream of sampling information from a plurality of power sources. Methods for overcurrent protection using an on-chip ADC are also described.

Methods, systems, and devices for wireless communication are described. A first device may receive a channel reservation request from a second device, over a shared or unlicensed radio frequency spectrum band, the channel reservation request including a first expected response time duration to receive a channel reservation response in response to the channel reservation request. The first wireless device may transmit a channel reservation response in response, and receive a directional transmission according to the channel reservation request. The second device may transmit a directional channel reservation request on a transmit beam, the directional channel reservation request including a first expected response time duration to receive a channel reservation response the first device in response to the directional channel reservation request. The second device may receive the channel reservation response during the first expected response time duration and transmit a directional transmission according to the directional channel reservation request.

The present disclosure relates to methods and devices for a handover procedure which may include a user equipment (UE), first base station, and a second base station. In one aspect, the UE can receive an indication to handover from the first base station to the second base station. The UE may then establish a connection with the second base station. In another aspect, the UE can maintain a connection with the first base station over a period of time during the handover. The UE can also communicate with the first base station and the second base station during the period of time based on a time division multiplexing (TDM) pattern. The TDM pattern can comprise a pattern of subframes for communicating with the first and second base station. In another aspect, the UE can release the connection with the first base station at the end of the period of time.

A transmission stream is generated. In the transmission stream, a first transmission packet where transmission media is included in a payload and a second transmission packet where information relating to the transmission media is included in the payload are time division multiplexed. The transmission stream is transmitted to a receiving side through a predetermined transmission path. If the transmission media included in the payload of the first transmission packet is file data configuring the predetermined contents, information relating to the predetermined contents is inserted into a header thereof. At the receiving side, the first transmission packet including the file data configuring the predetermined contents can be acquired easily and accurately based on the information.

The present invention relates to a method in a UE served by a network node, a method in the network node, the UE, and the network node. The network node is applying dynamic TDD with flexible subframes. The method comprises receiving a first configuration message from the network node indicating a TDD reference configuration, and determining in which subframe to signal HARQ information based on the TDD reference configuration. The method further comprises receiving a second configuration message from the network node indicating a set of DL subframes that may comprise explicit signaling messages, monitoring the indicated set of DL subframes, and receiving an explicit signaling message in response to monitoring. The explicit signaling message designates a subframe in which the UE shall receive a DL signal. The method also comprises preparing to receive the DL signal in the designated subframe.
