Systems and methods are provided for electronically distributing messages over communication channels. In accordance with one implementation, a system is provided that comprises at least one database for storing instructions for operating an input field and transmitting messages over a plurality of different communication channels, and at least one processing system configured to execute the instructions, to perform a method. The method may include displaying to a user, over a network, an input field for entering messages and receiving from the user, over the network and by entry into the input field, a message, an identification of one or more recipients, and a selection of at least one communication channel. The method may also include determining whether an identifier is stored in relation to each recipient for the selected communication channel and electronically sending, to each recipient with a stored identifier, the message via the selected communication channel.

Methods and devices for selectively presenting a user interface in a dual screen device. More particularly, the method includes providing a gallery for the dual screen device. The gallery can present one or more images in a user interface. The gallery user interface can adapt to changes in the device configuration. Further, the gallery can display images or videos in the various configurations.

The present disclosure relates to a user device, a base station, a method for data transmission/reception by a user device, and a method for data reception/transmission by a base station. The user device comprises circuitry which, in operation, receives a parameter defining a rule for assigning to ports respective resources for carrying reference signals, generates, based on a mapping known to the user device and the base station, a set of layer-to-port mapping combinations, and receives, from the base station, control information indicating one of the set of layer-to-port mapping combinations which is to be applied for data transmission and/or reception.

A device, system and method for dynamically adjusting a queue structure and message sequencing is provided. A device receives, from one or more edge devices receiving outbound signaling messages on one or more control channels, rankings of previously transmitted outbound signaling messages. The device adjusts (and/or causes adjusting of) one or more of a queue structure and a message sequence of the outbound signaling messages based on the rankings. The device transmits (and/or causes transmission), to the one or more edge devices, the outbound signaling messages according to one or more of the queue structure and the message sequence, as adjusted.

A first electronic device comprises a communication circuitry, and a memory configured to store instructions, and at least one processor coupled with the communication circuitry; wherein the at least one processor is configured to receive, from a second electronic device that is an upper node of the first electronic device, information regarding a specified waveform; while detecting that a vehicle associated with the first electronic device is not in an emergency state after receiving the information, transmit, to the second electronic device, a signal based on resources allocated from the second electronic device; and in response to detecting that the vehicle is in the emergency state alter receiving the information, transmit, to the second electronic device, a signal with the specified waveform independently from the allocated resources, wherein the signal with the specified waveform includes information for notifying that the vehicle is in the emergency state.

A resource configuration method, a terminal and a base station are provided. The resource configuration method applied to a terminal includes: receiving an activation state configuration command of a preconfigured bandwidth part (BWP) resource transmitted by a base station; configuring the resource of the BWP according to the activation state configuration command.

Proposed is a method for performing wireless communication by a first device. The method may comprise a step of receiving a channel state information reference signal (CSI-RS) through a physical sidelink shared channel (PSSCH) from a second device, measuring a channel state through the CSI-RS on the basis of a reference type associated with the PSSCH, and transmitting information about the channel state to the second device. For example, the reference type associated with the PSSCH may be determined on the basis of whether a slot including a resource associated with the PSSCH includes a resource associated with a physical sidelink feedback channel (PSFCH).

Embodiments of the present application provide a BWP switching method and a terminal device. The method includes: measuring, by a terminal device, a plurality of downlink reference signals corresponding to a plurality of downlink BWPs; and determining, by the terminal device, whether to switch from a first downlink BWP to a second downlink BWP according to measurement results of the plurality of downlink reference signals corresponding to the plurality of downlink BWPs. The first downlink BWP is an active BWP, and the first downlink BWP and the second downlink BWP belong to the plurality of downlink BWPs.

Certain aspects of the present disclosure provide techniques for resource allocation and hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback for multi-cell scheduling. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a configuration for a plurality of carriers, receiving, from the BS, control information indicating whether resources for a data channel are allocated in a concatenated pair of carriers of the plurality of carriers, and communicating on the data channel with the BS based on the control information.

Provided is a method and device for determining a codebook subset and a user equipment. In the method, a UE receives first indication information from a network device, the first indication information is used to indicate a first sounding reference signal (SRS) resource in an SRS resource set; the UE receives first configuration information from the network device, the first configuration information is used to configure codebook subsets; and the UE determines a codebook subset for uplink transmission based on the first indication information and the first configuration information.
