Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method includes receiving broadcast information from a base station that identifies types of resources for vehicle-based sidelink communications that are supported by the base station and transmitting a request to the base station for resource scheduling information to perform a vehicle-based sidelink communication based on the broadcast information. In some cases, the request includes an indication of a type of resources for the vehicle-based sidelink communication supported by the base station and a quality of service (QoS) metric associated with the vehicle-based sidelink communication. In some cases, the method further includes receiving, in response to the request, a response from the base station that comprises the resource scheduling information to perform the vehicle-based sidelink communication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify first set of metrics associated with a radio link monitoring procedure on a radio link and identify a second set metrics associated with a procedure for monitoring whether communications of a first service type or having a first quality of service requirement are supportable. The UE may monitor the radio link based on the first set of metrics to assess for radio link failure and monitor at least a portion of the radio link based on the second set of metrics. The UE may determine that a component of the radio link fails to satisfy the second set of metrics, and the UE may transmit an indication of the determination to the base station. The UE and the base station may update the radio link without declaring radio link failure.

The method includes receiving media access control (MAC) address information of a terminal from the terminal through an external device, registering the received MAC address information, and determining whether the registered MAC address information corresponding to MAC address information registered to another AP device. In response to the registered MAC address information corresponding to the MAC address information registered to the other AP device, an AP device managing the registered MAC address information is determined among the AP device and the other AP device. A connection request is received from the terminal, and the terminal is connected to the AP device based on whether MAC address information of the connection request is corresponding to the registered MAC address information.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with a carrier aggregation (CA) configuration, which may include a large number of component carriers (CCs). Some of the CCs may be designated as basis CCs, and may have a flexible control channel configuration, while other CCs may be designated as supplemental CCs with a restricted control channel configuration. The restricted control channels may have a reduced number of decoding candidates, which may reduce the complexity and increase the likelihood of successfully decoding the control channels. For example, the restricted control channels may be limited to a subset of aggregation levels, a reduced control region, or other restrictions. In some cases, the CCs may be grouped into basis CCs and supplemental CCs based on physical uplink control channel (PUCCH) groups or based on CCs that utilize enhanced physical downlink control channels (ePDCCH).

Abstract: In a case that a large number of terminal apparatuses accommodated in a contention based radio communication technology share a frequency resource, the number of data signals of the terminal apparatuses which are non-orthogonally multiplexed in the spatial domain increases. Therefore, in a case that the number of non-orthogonally multiplexed data signals of the terminals is considerably large, residual interference after removing interference in the reception processing degrades transmission performance.

Abstract: In some examples, a user equipment (UE) is registered with a fifth generation (5G) core network. In response to an emergency indication, the UE selects a first domain intended for a call responsive to the emergency indication.

In response to attempting the combined registration, the UE receives a further indication that the UE is registered for packet switched services but not circuit switched services. In response to the further indication, the UE selects an access network connected to a third core network to perform the call.
