Abstract: In some wireless communications systems, devices may support minimization of drive test (MDT) reporting, quality of service (QoS) reporting, and quality of experience (QoE) measurements. A user equipment (UE) and the serving base station may obtain measurements in accordance with a measurement configuration that indicates various triggering events or reporting adjustment factors associated with the measurements. The measurement configuration may indicate a triggering event such as the start of an application or service at the UE, and the UE may obtain MDT or QoE measurements based on identifying the application or service. Additionally, the serving base station may obtain MDT and QoE measurements based on identifying the application and service or a notification from the UE. The UE and the serving base station may identify reporting adjustment factors based on network slicing, area configurations and times of the day affecting the reporting interval and reporting amount for the measurement report.

Abstract: Methods, systems, and devices for wireless communications are described. A communication link between the UE and a serving base station may be established. The UE may measure, at an application layer of the UE, a set of quality of experience variables associated with different service types. The UE may measure, at an access stratum of the UE, a set of radio resource management variables associated with the communication link between the UE and the serving base station and a communication link between the UE and a corresponding set of one or more neighboring base stations associated with the communication links. The UE may transmit a measurement report to the serving base station indicating information associated with the quality of experience variables and the radio resource management variables in a multi-layer readable format.

Abstract: Methods for performing a handover in wireless communications for a user plane function (UPF) are disclosed. In an aspect, the method includes establishing a tunnel between the UPF and a target base station based on information in a path switch preparation request for a make before break handover of a user equipment (UE) from a source base station to the target base station, the path switch preparation request being received in response to a request originating by the target base station. The method further includes bi-casting a downlink data packet unit (PDU) to a source base station and to the target base station with a same sequence number (SN) in a tunnel protocol, receiving PDUs from the source base station and the target base station with corresponding PDUs having the same SNs in the tunnel protocol and discarding received duplicate PDUs based on the SNs in the tunnel protocol.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) may monitor a pre-wakeup window during an inactive duration of a multicast discontinuous reception (DRX) cycle that includes multiple active durations and multiple inactive durations. The UE may receive, in the pre-wakeup window, a wakeup signal that indicates a quantity of the active durations in the multicast DRX cycle that the UE is to monitor and the UE may monitor the indicated quantity of active durations for multicast signals for the UE.

Abstract: The disclosure relates to methods, devices, and systems for wireless communications. In some wireless communications systems, a base station may transmit a multicast message to a group of user equipment (UEs), and the UEs may provide feedback for the multicast message. In some implementations, the base station may configure the UEs to transmit feedback for multicast messages. In some example, the UEs may transmit group-negative acknowledgment (NACK) feedback information for multicast messages that are not successfully received at the UEs. In some other examples, each UE may be configured with UE-specific uplink control channel resources for transmitting hybrid automatic repeat request (HARQ) feedback for a multicast message. In some implementations, a UE may support feedback for both unicast and multicast messages. The semi-static codebook for unicast, multicast, or both may account for whether the UE is capable of concurrently receiving unicast and multicast messages in a slot.

Abstract: Wireless communications systems and methods related to on-demand ultra-reliable, low-latency communication (URLLC) are provided. In one embodiment, a base station (BS) receives, from a user equipment (UE) in a first cell frequency, a request for a protocol data unit (PDU) session over a network slice. The BS receives, from a core network entity, a resource configuration request for the PDU session over the network slice. The BS transmits, to the core network entity, a resource configuration response indicating a cause for rejecting the resource configuration request. In one embodiment, a UE transmits, in a first cell frequency of a network, a network registration request message requesting a network slice of the network that is not provided by the first cell frequency. The UE receives a network registration response message indicating the network slice is allowed based on a second cell frequency of the network providing the network slice requested.

Abstract: Methods, systems, and devices for wireless communication are described that provide for sharing or isolating network resources between multiple cells in a system. Resources are allocated to multiple cells and multiplexed according to a time division multiplexing (TDM) scheme where a portion of a component carrier is shared between multiple cells. The allocation of resources also includes splitting or sharing a portion of the time resources between two or more cells such that a subframe is allocated as a subframe shared between multiple cells or as a subframe dedicated for use by only a single cell.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a service through an MBMS session. The apparatus receives a first notification of an upcoming suspension of the MBMS session. The apparatus requests establishment of a unicast bearer prior to the upcoming suspension of the MBMS session upon receiving the first notification. The apparatus receives a corresponding unicast version of the service of the MBMS session via unicast when the unicast bearer is established. In an aspect, the first notification may be received during a first MCCH modification period, the corresponding unicast version of the service is received via unicast during a second MCCH modification period. In an aspect, the apparatus may further receive a second notification that the MBMS session is suspended during the second MCCH modification period.

Abstract: Systems and techniques are disclosed to reduce workload on base stations in a mobile network when content delivery networks cache content inside the network. A user equipment sets a flag only with those packets on the uplink which include requests that should be routed to the cache server inside the mobile network. The base stations perform deep packet inspection of those packets where flags have been set and forward other packets on to the rest of the relevant backhaul of the mobile network. After deep packet inspection, the base stations either route the packet to the cache server via an established connection or propagate the flag in an extension header to another network node for routing to the cache server. The resulting content is returned to the UE with the source address of the originally intended destination instead of the cache server, rendering the process transparent to the end user.
