Abstract: An access node may provide synchronization information to a UE. The access node may further provide one or more information blocks, which may include basic network configuration information. Based on the synchronization information and/or the information block(s), the UE may transmit a message to the access node that includes a random access preamble, an identifier of the UE, and/or a buffer status report. Based on the message from the UE, the access node may determine that the UE should remain active and, therefore, may transmit a response to the first message to the UE indicating that the UE should remain active. Thereafter, the UE may receive a connection setup or connection reconfiguration message. The connection setup or reconfiguration message may be received from the same or different access node from which the UE received the synchronization information and/or the one or more information blocks.

Abstract: Methods, systems, and devices for wireless communications are described that provide for configuration of channel bandwidth that may be specific to a particular user equipment (UE). A UE may be configured with a channel bandwidth that is less than or equal to a channel bandwidth of the serving base station, and may also be different than a channel bandwidth of one or more other UEs that are served by the base station. The base station may signal the UE-specific channel bandwidth in UE-specific signaling, such as UE-specific radio resource control (RRC) signaling.

Abstract: A wireless network may provide system information by either a fixed periodic broadcast or broad-beam transmission or in response to a request by a user equipment (UE). The wireless network may broadcast (or broad-beam transmit) a signal that indicates to the UEs within a cell or zone coverage area that system information is to be transmitted on a fixed periodic schedule or in response to a request sent by one or more UEs.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying, while the UE is in a connected mode with a network, a radio resource configuration of the UE, selecting a dedicated set of resources for the UE or a common set of resources for a plurality of UEs based at least in part on the identified radio resource configuration, and transmitting a pilot signal to the network using the selected set of resources. Methods for wireless communication at a network access device and a network access device controller are also described.

Abstract: Aspects of the present disclosure provide methods and apparatus for transmitting an uplink reference signal, receiving a keep alive (KA) command based, at least in part, on the uplink reference signal, and taking one or more actions to perform a handover to a non-serving base station (BS) in accordance with the KA command. Additionally, aspects provide methods and apparatus for receiving an uplink reference signal from a user equipment (UE), measuring the uplink reference signal, and transmitting a KA command to the UE based, at least in part, on the measured uplink reference signal. The KA command may be scrambled by an identifier associated with the UE. Additionally or alternatively, a cyclic prefix (CP) of the uplink reference signal may be longer than a CP of another type of reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may transmit and a user equipment (UE) may receive cloned bandwidth part configuration information. In some aspects, the UE may determine a linkage between a primary bandwidth part and the cloned bandwidth part. In some aspects, the BS may transmit and the UE may receive a downlink control information message identifying the primary bandwidth part to signal a bandwidth part switch for the primary bandwidth part and a first bandwidth part or identifying the cloned bandwidth part to signal the bandwidth part switch for the primary bandwidth part and a second bandwidth part. In some aspects, the UE may perform the bandwidth part switch based at least in part on the downlink control information message. Numerous other aspects are provided.

Abstract: Methods and apparatuses of wireless communications are provided to dynamically determine capability information such that potential configuration and/or resource conflicts may be mitigated among multiple connections while one or more of on-going connections are not interrupted. A user equipment (UE) establishes one or more connections with a network. The UE allocates, in a first resource allocation, one or more resources of the UE to the one or more connections. The UE dynamically determines an instantaneous UE capability information (IUCI) of the UE in response to a change from the first resource allocation to a second resource allocation, the IUCI indicative of the capability of the UE during a predetermined time period. The UE transmits the IUCI to the network to mitigate potential resource allocation conflict among the one or more connections while maintaining at least one of the connections.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to operate in dual connectivity (DC) and with split radio bearers, such that one or more split radio bearers are associated with a first cell group and one or more split radio bearers are associated with a second cell group. In some cases, a cell group failure may occur. Accordingly, the UE may autonomously update one or more radio bearer configurations of the split radio bearers to determine a processing scheme for the cell group failure. Additionally or alternatively, as a result of the cell group failure, an amount of unacknowledged data in a radio link control (RLC) buffer for the second cell group may get stuck such that the network cannot access it. Accordingly, the UE may perform a PDCP data recovery (e.g., user plane handling) to access the unacknowledged data.
