Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. A user equipment (UE) may acquire a triggering synchronization signal block (SSB), which enables the UE to monitor for a floating Type-2 physical downlink control channel (PDCCH) and to determine a subset of paging occasions (POs) to monitor. Or, the UE may monitor for a fixed Type-2 PDCCH, where the UE does not require a triggering signal to monitors POs. In another aspect, the UE may monitor for a paging transmission during a monitoring period. The UE may determine the monitoring period based on received signaling. The UE may receive the signaling, during the monitoring period, indicating that the monitoring period is to be ended before a scheduled end of the monitoring period. In this way, the UE may support a continuity requirement associated with downlink reference signaling (DRS) and may support reception of paging in a shared channel.

Abstract: Wireless communications systems and methods related to DL control message monitoring are provided. A first wireless communication device monitors for a downlink control message from a base station during a first monitoring duration. Additionally, the first wireless communication device monitors for a network activity indication signal from the base station during the first monitoring duration. The first wireless communication device detects the network activity indication signal based on the monitoring of the network activity indication signal. The first wireless communication device switches from the first monitoring duration to a second monitoring duration for the monitoring of the downlink control message in response to detecting the network activity indication signal.

Abstract: A configuration to enable a UE to obtain access to an unlicensed frequency channel of the unlicensed frequency spectrum in the event of channel access failures. The apparatus performs a radio link monitoring (RLM) for a first unlicensed frequency channel of an unlicensed frequency spectrum for a transmission from a first base station. The apparatus determines that the first unlicensed frequency channel is unavailable for the transmission based on a comparison of one or more of a reference signal received power (RSRP), a reference signal received quality (RSRQ), a received signal strength indicator (RSSI), a signal to interference plus noise ratio (SINR), a signal to noise ratio (SNR), or a channel occupancy or interference metric to a corresponding threshold. The apparatus sends a report to the first base station indicating a failure of the transmission upon determining that the first unlicensed frequency channel is unavailable for the transmission.

Abstract: A UE determines to send a transmission to a first base station on a first unlicensed frequency channel. The UE determines, for one or more attempts of a listen before talk (LBT) protocol, whether each attempt is a failed attempt or a successful attempt. The UE determines that the first unlicensed frequency channel is one of unavailable based on the LBT protocol failing due to a number of failed attempts exceeding for a first threshold number of failed attempts or a duration of failed attempts exceeding a first threshold duration, or available based on the LBT protocol being successful. The UE sends a report to the first base station indicating whether the first unlicensed frequency channel is unavailable or available through a unicast radio resource control (RRC) message or a medium access control (MAC) control element (CE).

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may select at least one target node for a radio resource control connection, wherein the user equipment is in a particular radio resource control communication state when the at least one target node is selected, and wherein the user equipment is configured to communicate using dual-connectivity, wherein context information associated with the user equipment is stored by the user equipment, a master node associated with the user equipment, and a secondary node associated with the user equipment based at least in part on the user equipment being in the particular radio resource control communication state; and/or transmit information to the at least one target node or the master node to cause the context information to be provided to the at least one target node. Numerous other aspects are provided.

Abstract: Uplink signaling in unlicensed or shared spectrum may be subject to listen before talk procedures resulting in failed signaling transmissions. A user equipment (UE) may perform uplink signaling using a configuration based on whether a base station has entered a channel occupancy time (COT) shared with the UE. A UE may determine that the UE has an uplink transmission for a base station. A UE may determine whether the base station has entered a channel occupancy time that is shared with the UE. A UE may determine configured random access or scheduling request transmission resources based on the channel occupancy time, wherein a density of transmission opportunities is greater outside of the shared channel occupancy time than within the shared channel occupancy time. A UE may transmit a random access message or the scheduling request on selected configured resources.

Abstract: Aspects presented herein provide for dual connectivity with a standalone service provider in the unlicensed spectrum. A first base station may receive, from a UE, an indication of a capability for standalone operation in a first RAT that utilizes an unlicensed frequency spectrum and a dual connectivity capability involving the first RAT and a second RAT that utilizes a licensed frequency spectrum, wherein dual connectivity comprises the UE being connected to a master base station on a first frequency and a secondary base station on a second frequency at a same time. The first base station may signal a first set of procedures for dual connectivity when the level of support at the first base station is at higher layers of the first RAT and may signal a second set of procedures when the level of support at the first base station extends to lower layers of the first RAT.

Abstract: Certain aspects of the present disclosure provide techniques for minimizing interruption for UL and/or DL transmission via a secondary link during a handover on a primary link. In response to a handover indication, a UE, source BS and target BS may take one or more actions to maintain an existing connection between the UE and a secondary link. For example, the UE, source BS, and target BS may take one or more actions to maintain a connection between the UE and a WLAN AP.

Abstract: Certain aspects of the present disclosure relate to techniques for aggregating data from a wireless wide area network (WWAN) and wireless local area network (WLAN). In some aspects, a packet convergence entity (e.g., PDCP layer entity) communicates with first and second radio access technology (RAT) links. The packet convergence entity may determine from which of the first and second RAT links a data packet is received and may monitor a sequence number value of each of the received data packets. The packet convergence entity may perform one or more actions based on a determination that one or more packets are missing based on the monitored sequence number values. The packet convergence entity may send a status report in response to one or more events on one or both of the first RAT link and the second RAT link.
