Methods and systems for easily establishing or switching between wireless connections by sending a Bluetooth Low-Energy (BLE) command from a first BLE enabled device to a second BLE enabled device, where the BLE command causes the second BLE enabled device to attempt to establish a Bluetooth Classic connection with one or more source devices from a list of source devices that have previously been paired with the second BLE device. The first BLE device is configured to obtain or receive the list from the second BLE device, and in response to one or more triggers, send the BLE command. The list of previously paired source devices may be presented to a user via a display screen with touch-screen functionality, and in some examples, may utilize one or more algorithms to intelligently order the available source devices based on a variety of factors.

Processes, methods, systems, and devices are disclosed for pairing a target device with a source device and pairing the target device with a partner device. A user may choose between using the target device and the partner device without actively connecting the partner device to the source device. The target device and the partner device may each be a specialized device providing certain functions. For example, the source device may be a computing device, such as a smart phone or a tablet computer. The target device may be a sound bar dedicated for playing high definition surround sound that outperforms internal speakers of the source device. And the partner device may be a noise-canceling headset. The user may want to seamlessly switch between playing sounds on the sound bard and the headset from time to time under different circumstances, without needing to manually pair the headset to the computing device.

An operation method of a first terminal in a communication system is provided. The method includes transmitting first SCI to a second terminal, the first SCI including one or more information elements among information indicating time resource(s) for sidelink communication, information indicating frequency resource(s) for the sidelink communication, information indicating a periodicity of physical resources for the sidelink communication, and information indicating an MCS for the sidelink communication. Second SCI is transmitted to the second terminal, the second SCI including information for an HARQ feedback operation and information indicating an NDI. The method further includes performing the sidelink communication with the second terminal based on the first SCI and the second SCI associated with the first SCI.

Embodiments of a User Equipment (UE) and methods for communication are generally described herein. The UE may be configured for carrier aggregation using a primary component carrier (CC) and a secondary CC. The UE may attempt to detect a sidelink synchronization signal (SLSS) from another UE on the primary CC. The UE may, if the SLSS from the other UE is detected: determine, based on the detected SLSS, a common time synchronization for the primary CC and the secondary CC for vehicle-to-vehicle (V2V) sidelink transmissions in accordance with the carrier aggregation. The UE may, if the SLSS from the other UE is not detected: transmit an SLSS to enable determination of the common time synchronization for the primary CC and the secondary CC by the other UE. The SLSS may be transmitted on the primary CC.

The same or similar physical signals can be used for both user equipment (UE) and an integrated access backhaul (IAB) node. Different configurations of resources and/or transmission periods of the signals can be used for initial access for access UEs and IAB nodes. In addition, since the UE functionality for IAB nodes is not fully identical with access UEs, the network can identify which UEs performing initial access are normal access UEs or are IAB nodes with UE functionality. Furthermore, the parameters for configuring radio resource management operation at the IAB node gNode B function can consider a half-duplex constraint imposed by the UE function and can also analyze hop order and other topology/route management functionalities.

There is provided a performed by a first node for use in connecting a remote user equipment (UE) to a cellular network. An identity of the remote UE is acquired (102). A cryptographic function is applied (104) to the identity of the remote UE to generate a string identity for the remote UE. The string identity for the remote UE is stored (106) in a memory with the identity of the remote UE for use in connecting the remote UE to the cellular network via a relay UE connected to the cellular network.

A method is provided to support remote UE transmitting recommended bit rate query to the base station via the processing of relay UE. In one novel aspect, a new sidelink MAC CE is introduced to indicate the desired bit rate for a specific sidelink logical channel or for a specific Uu/SL radio bearer. In one novel aspect, after receiving the recommended bit rate query MAC CE, the relay UE forwards the MAC CE of this remote UE to the base station over Uu interface after adding information related to remote UE identity. In one novel aspect, the recommended bit rate query MAC CE, when received by the relay UE, is mapped to a specific uplink logical channel priority value or a specific uplink logical channel priority level, which can be used to compare priority with other UL data or UL MAC CE.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, an indication of a first sidelink grant associated with a first set of resources. The UE may receive, from the network entity, an indication of a second sidelink grant associated with a second set of resources, wherein the first set of resources at least partially overlaps in a time domain with the second set of resources. The UE may perform an action based at least in part on the first set of resources at least partially overlapping in the time domain with the second set of resources. The UE may transmit one or more sidelink messages using at least one of the first sidelink grant or the second sidelink grant based at least in part on performing the action. Numerous other aspects are described.

Techniques for establishing communication channels between user devices experiencing network connectivity issues and remote communication systems are described herein. The techniques include the use of a secondary device to act as a proxy, or a “middle man,” to facilitate the communications with the user device. A user device may detect lack of network connectivity, and begin broadcasting advertisement messages that indicate the lack of connectivity. A secondary device may detect the advertisement message, and send a discovery message to a connectivity system indicating that it detected the advertisement message. The connectivity system can provide this information to a remote communication system, and the remote communication system can establish a connection with the secondary device and instruct the secondary device to establish a connection with the user device. The remote communication system then has a communication channel with the user device, using the secondary device, to troubleshoot the user device.
