Abstract: A method of collecting and providing traffic statistics in a cellular network in accordance is proposed. A UE establishes an RRC connection with a base station. The UE starts to collect traffic statistics that comprises a CDF curve or a PDF diagram for packet inter-arrival time. The UE may receive a measurement configuration from the base station for the traffic statistics collection. The UE then reports a representation of the traffic statistics to the base station for RRC reconfiguration. The UE may also receive a reporting request from the base station that specifies a representation format. The representation format includes one or more probability values at corresponding inter-arrival time points, at least one slope of the CDF, one or more steep events in the CDF, or a PDF range.

Abstract: Various methods for wireless communication in a device with co-existed/co-located radios are provided. Multiple communication radio transceivers are coexisted/co-located in a user equipment (UE) having in-device coexistence (IDC) capability, which may result in IDC interference. For example, the UE is equipped with both LTE radio and some ISM band applications such as WiFi and Bluetooth modules. In a first method, the network identifies IDC capability by UE identification (e.g., UE ID). In a second method, the UE intentionally performs cell selection or reselection to cells in non-ISM frequency bands. In a third method, the UE signals the existence of ISM band applications via capability negotiation. In a fourth method, the UE signals the activation of ISM band applications by signaling messages (e.g., RRC message or MAC CE). Under the various methods, the UE and its serving eNB can apply FDM or TDM solutions to mitigate the IDC interference.

Abstract: A method and apparatus for active location acquisition. An active location acquisition controller is included in a device. The active location acquisition controller can be a circuit or code running on a processor included in the device. A measurement collection request is communicated to the device. The device then determines if and how a location information is to be acquired. If the device determines that the location information is to be acquired, the device enables a location acquisition system to acquire the location information and the device then acquires the requested measurement and stores the requested measurement and the location information in the measurement log. If the device determines that the location information is not to be acquired, the device disables a location acquisition system and does not acquire the location information and the device then acquires the requested measurement and stores the requested measurement in the measurement log.

Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. In one embodiment, the access information comprises mapping information between the TMGI and the communication group ID.

Abstract: A method of reporting UE measurement state information in RLF report is provided. A UE performs radio measurements of a serving cell and neighbor cells in a mobile communication network. The UE evaluates a measurement reporting criteria and attempts to access the network to deliver a measurement report if the criteria is met. The UE then detects a radio link failure or a handover failure event and reconnects to the network by performing RRC reestablishment or RRC establishment. Finally, the UE transmits a failure event report to the network. The failure event report comprises UE measurement state information corresponds to the failure event. The UE measurement state information helps the network to determine whether to apply corrective actions to mitigate the failure.

Abstract: An enhanced connection recovery upon lost RRC connection due to radio link failure (RLF) or handover failure (HOF) is proposed. A UE first establishes an RRC connection in a source cell in a mobile communication network. Later on, the UE detects a failure event and starts an RRC reestablishment procedure in a target cell to restore the RRC connection. In a first novel aspect, a fast NAS recovery process is applied to reduce the outage time in the target cell. In a second novel aspect, context fetching is used to reduce the outage time in the target cell. In a third novel aspect, a loss-less reestablishment procedure is proposed to reduce data loss during the connection recovery.

In one embodiment, the UE-assisted tethering report includes one or more elements comprising one bit to inform the activation of tethering mode, latency of packet transmission, and other side-information related to tethering path. In one embodiment, the UE-assisted procedure is inserting a measurement timestamp or recording timing of a predefined transport block (TB) of the packet. In another novel aspect, the UE performs a jitter measurement for an extended reality (XR) traffic, sends a UE-assisted information report for an end-to-end path of the XR traffic based on the jitter measurements, wherein the UE-assisted information includes one or more elements comprising jitter information and burst arrival time.

Abstract: A method to speed up uplink data access during a radio resource control (RRC) reconfiguration procedure is proposed. UE first sends an RRC request, and in response receives an RRC reconfiguration message from BS. UE then decodes the RRC reconfiguration message and performs reconfiguration. UE also waits for UL grant for transmitting RRC reconfiguration complete with UL data if available. In one embodiment, BS provides the UL grant in a common search space while UE is performing the reconfiguration, and UE does not need to wait the UL grant until after the reconfiguration is done. In other words, the reconfiguration and the UL grant occurs in parallel, which reduces access delay for UL data. In an alternative embodiment, BS provides UL grant in RRC reconfiguration message, so that UE does not have to receive UL grant while performing the reconfiguration.

The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. In one embodiment, The UE requests to switch the DL multicast traffic from the multicast MBMS bearer to the unicast bearer upon detecting that the UE is approaching an MBMS coverage boundary. In another embodiment, the UE transmits an indication of preferred target cells to the network before performing a handover and thereby maintaining multicast service continuity of the group communication.

Abstract: A method can include receiving measurement configurations for measuring serving/neighboring cells at a user equipment (UE) in a wireless communication system. The measurement configurations can indicate multiple measurement objects (MOs) each with a SSB measurement timing configuration (SMTC) specifying a sequence of SMTC window durations (i.e. SMTC occasions), and a sequence of gap occasions. The MOs can be measured within the SMTC occasions that overlap the gap occasions. The method can further include determining a carrier-specific scaling factor for a target MO in the multiple MOs based on candidate MOs to be measured in each of the gap occasions.
