Provided are a method for a terminal to perform frequency measurement on the basis of a cell specific priority in a wireless communication system, and an apparatus for supporting the same. The terminal may be configured to: receive the cell specific priority and a frequency specific priority from a network; compare a cell specific priority of a first cell and a frequency specific priority of the frequency to which the first cell belongs; determine whether to apply the cell specific priority of the first cell to the frequency to which the first cell belongs; and perform frequency measurement on the basis of the determined priority. The first cell is a cell for which a cell specific priority is set, and the cell specific priority may be set to be the same for each frequency.

The present disclosure describes methods, devices, and systems for signal strength measurement. An example method includes: broadcasting, by a first relay device, a first message, wherein the first message is used by a first remote device to discover the first relay device; establishing, by the first relay device, a connection to the first remote device; and sending, by the first relay device, a second message, wherein the second message is used by the first remote device to measure signal strength of a link between the first remote device and the first relay device.

Systems and methods are disclosed for communicating enhanced user equipment (UE) assistance information between nodes in wireless communication systems. The UE achieves power savings and latency requirements more effectively by communicating its preferences, constraints and/or requirements to an evolved Node B (eNodeB) in the form of UE assistance information. The UE assistance information may include, for example, an indication of a preferred set of discontinuous reception (DRX) settings, current data traffic conditions, expected data traffic conditions, power or performance preferences, and/or an indication of the UE's mobility between cells.

Aspects of the subject disclosure may include, for example, determining a demand for real-time services to a first mobile device, by way of a base station of an LTE system. In response, utilization of a first wireless channel of a first radio of the base station is evaluated. The first radio supports a first wireless service that includes the real-time service and a non-real-time service to a second mobile device within the same cellular region. A handover of the second mobile device to a second radio of the base station is facilitated in response to the utilization. The second radio is configured to support a second wireless service that excludes the real-time service within the same cellular region. Responsive to the handover, the second radio supports the non-real-time service over the second wireless channel to the second mobile device within the cellular region. Other embodiments are disclosed.

In an aspect of the disclosure, an apparatus is provided. The apparatus receives a downlink data packet and determines a service data flow associated with the downlink data packet. The apparatus extracts, from the downlink data packet, a Non-Access Stratum (NAS) Reflective QoS Indication (RQI) indicator that instructs the UE to map a service data flow to the QoS flow. The apparatus further extracts, from the downlink data packet, a Quality of Service (QoS) flow identifier identifying a QoS flow. The apparatus generates a first NAS mapping that maps the service data flow to the QoS flow, in response to a determination that the service data flow is not mapped to the QoS flow at the apparatus. The apparatus further transmits, in accordance with the first NAS mapping, an uplink data packet associated with the service data flow through the QoS flow.

Apparatuses, methods, and systems are disclosed for indicating data status to a target base unit. One apparatus includes a transceiver that communicates with a remote unit and a processor. The processor determines to handover the remote unit to a target base unit. The processor forwards data for the remote unit to the target base unit and transmits the forwarded data to the remote unit. The processor also sends a status message to the target base unit, the status message indicating that forwarded data was successfully transmitted to the remote unit.

Disclosed in the present disclosure is a mobility optimization method. The method includes that a User Equipment (UE) having a small data feature performs, when determining that a cell supporting an optimized small data processing capability exists in candidate cells during execution of cell reselection, the cell reselection according to information of a small data priority cell reselection principle. Also disclosed is another mobility optimization method, including that a network side provides cell reselection information to a UE having a small data feature and normally residing in a cell; the cell reselection information includes information of a reselection principle including a small data processing capability factor and/or capability information indicating whether a network supports optimized small data processing or not; during execution of switching, a target Evolved Node B (eNB) having an optimized small data processing capability and satisfying a switching condition is selected preferentially for the UE having the small data feature, and a switching request message is sent to the selected target eNB. Also disclosed are a UE and an access network device.

A device obtains uplink information associated with a base station and obtains downlink information associated with a mobile device in communication with the base station. The device determines observed network performance information based on the uplink information and the downlink information and determines a predictive model, based on the uplink information and the downlink information, to predict network performance information. The device also changes network configuration data, associated with the base station, to generate changed network configuration data and determines predicted network performance information for the changed network configuration data based on the predictive model. The device further selectively transmits the changed network configuration data, to the base station, based on comparing the predicted network performance information and the observed network performance information.

A reception unit receives from a wireless relay device, a handover response indicating possibility of degradation in communication quality during wireless communication with the wireless relay device. A search unit searches whether or not a wireless relay device to which handover can be performed is present other than the wireless relay device. When the wireless relay device to which handover can be performed other than the wireless relay device is present as a result of search by the search unit, a transmission unit transmits a handover request to the wireless relay device found by the search unit.
