Systems, apparatuses, and methods are described for wireless communications. A wireless device may have different capabilities for preemption. A base station may use a signaling format to indicate a transmission power command and a preemption indicator. A wireless device may receive the signaling format and may determine, based on the transmission power command and the preemption indicator, whether to stop a transmission or to reduce a transmission power.

For scheduling transmissions of data channels, control channels, or random access channels using downlink control information (DCI) formats, a DCI format can configure a transmission of one or multiple data channels over respective one or multiple transmission time intervals. A first DCI format can configure the parameters for a channel transmission and a second DCI format can trigger the channel transmission and indicate respective one or more transmission time intervals.

A method and apparatus for transmitting a power headroom report (PHR) in a wireless communication system is provided. A user equipment (UE) transmits a first PHR for a first carrier group, which is configured by a first eNodeB (eNB), to a second eNB; and transmits ing a second PHR for a second carrier group, which is configured by the second eNB, to the first eNB. The first PHR and the second PHR include a PHR for a physical uplink control channel (PUCCH) regardless of whether simultaneous transmission of the PUCCH and a physical uplink shared channel (PUSCH) is configured or not.

A method of includes receiving hotspot identification data from the first device, where the identification data identifies a plurality of WiFi hotspots that are in proximity to the first device; determining that the second device is associated with the first device; sending the hotspot identification data to the second device, where the first device and second device are mobile devices; receiving an indication of proximity from the second device; and notifying the first device of the indication of proximity.

Systems, methods, and apparatuses are described for wireless communications. A wireless device may transmit an uplink signal via a cell of a cell group. Transmission timing of the uplink signal may be based on a cell of the cell group and a timing adjustment associated with a different cell group.

Disclosed are a V2X (vehicle-to-everything) transmission resource selecting method implemented by a terminal in a wireless communication system and a terminal using the method. The method is characterized by: receiving type information for indicating the type of a resource pool; and executing a resource selection, on the basis of partial sensing, and/or a random selection from the resource pool on the basis of the type information.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a cancellation indication associated with an uplink transmission on a shared radio frequency spectrum band, the shared radio frequency spectrum band having a listen-before-talk channel access mechanism to access the shared radio frequency spectrum band; determine, based at least in part on the reception of the cancellation indication associated with the uplink transmission on the shared radio frequency spectrum band, whether the uplink transmission is to be cancelled or transmitted at a reduced transmit power; and when the uplink transmission is to be transmitted at the reduced transmit power, transmitting the uplink transmission at the reduced transmit power. Numerous other aspects are provided.

Various implementations include approaches for establishing a Bluetooth (BT) connection between devices. One example approach includes: in response to a trigger at a first Bluetooth (BT) device, attempting to determine a received signal strength indicator (RSSI) from each of a set of additional Bluetooth (BT) devices paired to the first BT device, in response to determining the RSSI for a first additional BT device and a second additional BT device in the set of additional BT devices, determining if the RSSI of each of the first additional BT device and the second additional BT device satisfies a threshold, and in response to determining that the RSSI of both the first additional BT device and the second additional BT device satisfy the threshold, selecting either the first additional BT device or the second additional BT device for connection with the first BT device.

A user equipment detects that an aggregate of calculated uplink transmit power of the UE exceeds a threshold. In response to the detecting, a power of at least one of a plurality of frequency-division multiplexing (FDM)-based uplink transmissions of the UE over corresponding wireless connections with respective wireless access network nodes is adjusted.

The present disclosure relates to a communication method and system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for internet of things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure discloses a transmission method and device. According to an aspect of the present disclosure, a method performed by a user equipment (UE) in a communication system is provided. The method includes: receiving, by the UE, configuration information from a base station, and determining a first number of connections scheduled by the base station based on the configuration information; determining a second number of connections that UE can establish simultaneously based on a first rule; selecting a second number of connections from the first number of connections based on a second rule.
