Apparatus and method for wireless communications that include RLM or BFD procedures. The apparatus measures one or more reference signals for an RLM procedure or a BFD procedure. The apparatus reduces a rate of the measuring the one or more reference signals for the RLM procedure or the BFD procedure based at least in part on at least one measurement of the one or more reference signals meeting a relaxation criteria.

A method and apparatus are disclosed. A base station configured to communicate with a user equipment is provided. The base station is configured to indicate a plurality of measurement reporting configurations associated with a measurement object configuration, and transmit control information to activate at least one of the plurality of measurement reporting configurations. The UE is configured to receive an indication of a plurality of measurement reporting configurations associated with a measurement object configuration, receive control information activating at least one of the plurality of measurement reporting configurations and report at least one measurement based at least in part on the activated at least one of the plurality of measurement reporting configurations.

A telecommunication network associated with a wireless telecommunication provider can be configured to dynamically switch the primary cell (PCell) used by user equipment (UE) for carrier aggregation (CA) in 5G cellular networks. Instead of remaining anchored to an initially selected PCell, a different PCell may be dynamically selected based on different network conditions. The network conditions may include network congestion, network capacity, uplink speed, location of the UE, an activity of the UE (e.g., is the UE uploading or planning to upload data), and the like. As an example, the PCell may be selected from an n41 (2.5 GHz) cell and an n71 (600 MHz) cell. When the UE is close to the n41 cell, the n41 cell may be selected. When the UE is moving away from the cell center and toward the cell edge, the PCell may be switched from the n41 cell to the n71 cell.

An embodiment of the present disclosure may provide an inter-MeNB handover method in a small cell system, including: making, by a source MeNB and/or target MeNB, a determination as to whether to maintain a SeNB when handover is performed; and triggering different handover processes according to a result of the determination as to whether to maintain the SeNB. Another embodiment of the present disclosure may further provide an inter-MeNB handover device in a small cell system. With the inter-MeNB handover method and device in a small cell system provided by the present disclosure, unnecessary deletion and re-establishment of the bearers at the SeNB for the UE may be reduced. False bearer deletion may be avoided and data forwarding may be reduced. Furthermore, the SeNB may be maintained according to network deployment and SGW re-selection may be supported. Therefore, system capacity and transmission speed of the data may be improved.

In a wireless User Equipment (UE), a serving radio wirelessly exchanges data with a serving cell over a serving radio band. The wireless UE wirelessly receives serving signaling that indicates serving uplink interference for the serving radio band at the serving cell. A neighbor radio in the UE wirelessly receives neighbor signaling. UE circuitry determines serving signal strength and the serving uplink interference for the serving cell. The UE circuitry determines neighbor signal strength for the neighbor cell. The UE circuitry compares the serving uplink interference and the serving signal strength to the neighbor signal strength, and in response, generates a handover request for the neighbor cell. The serving radio wirelessly transfers the handover request to the serving cell, and in response, the neighbor radio wirelessly exchanges additional data with the neighbor cell over the neighbor radio band.

A method for transmitting a channel state by a terminal in a communication system, according to one embodiment, comprises the steps of: receiving discontinuous reception (DRX) configuration information from a base station; determining whether the terminal is set to transmit channel state information only in onDuration according to a DRX operation; determining whether an arbitrary subframe to be received is a subframe included in onDuration if the terminal is set to transmit the channel state information only in onDuration according to the configuration; and not transmitting the channel state information on the arbitrary subframe if the arbitrary subframe is not a subframe included in onDuration. According to the embodiment, the terminal can efficiently report channel state information.

There is provided a method comprising: upon detecting that a first condition is met, causing a transmission of a measurement report to a wireless network; acquiring a conditional handover command from the wireless network; upon detecting that a second condition, associated with the conditional handover command, is met, starting a handover execution timer for triggering execution of a handover from a source cell to a target cell; detecting that a radio link failure condition is met before the execution of the handover is triggered; and on the basis of the detecting, signaling, to the wireless network, information indicative of a cause of a conditional handover failure to be either misconfigured first condition or misconfigured second condition.

A first beam is implemented, from a set of vehicle-based antennas, for current or future communication with a ground-based or satellite-based network via an external antenna (e.g., of a base station or satellite). A second beam may be implemented to detect or determine a better pointing angle for the first beam, thereby “fine tuning” the pointing angle for the first beam. Specifically, the second beam may be “swept” through a range of pointing angles while a signal parameter representing signal quality or strength is measured, detected, or calculated at each pointing angle. The values for the signal parameter may be evaluated to identify a desired value and the pointing angle at which the desired value was obtained. The first beam may be reoriented or repointed at the desired pointing angle, and one or more nodes of vehicle-based communication system may communicate with an external network via the first beam.

A method and apparatus for predicting measurements in a wireless communication system is provided. A wireless device receives, from a network, a measurement configuration including (i) a measurement object, and (ii) a reporting condition. A wireless device derives (i) at least one predictive measurement result for the measurement object and (ii) a prediction time at which the at least one predictive measurement result being satisfied the reporting condition. A wireless device transmits (i) information on the at least one predictive measurement result and (ii) information on the prediction time.

Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform to perform cell detection and measurement, e.g., in new radio (NR) unlicensed (NR-U). The UE may determine that a threshold condition related to missed reference signal opportunities is reached. In response, the UE may modify reference signal monitoring and/or measurement.
