APPARATUS CONFIGURED TO APPROXIMATE A POWER COEFFICIENT IN A CELL-FREE MASSIVE MIMO WIRELESS SYSTEM AND METHOD OF PERFORMING SAME
A central node may include a processor configured to empirically compute an approximation of power coefficients based on estimates of the channel coefficients such that a same one of the approximation of the power coefficient is assigned to each of a plurality of access terminals (ATs), and transmit components of a signal vector to associated access points (APs), the signal vector being based on at least the approximation of the power coefficient.
USER EQUIPMENT AND NETWORK NODE FOR CONFIGURING MEASUREMENTS OF CELLS AND BEAMS IN A WIRELESS COMMUNICATION SYSTEM
Configuration of measurement requirements on cells and beams in NR is made more efficient by, in a user equipment, UE, recieving, information from a network node, which information indicates: a first number K of beams to be measured by the UE, and a second number L of cells in which the UE is required to measure the first number K of beams. The UE then carries out measurements using the received information; and performs at least one operational task based on a result of the measurements.
CELL MEASUREMENT METHOD, MEASUREMENT APPARATUS, TERMINAL DEVICE, CHIP, AND STORAGE MEDIUM
A cell measurement method. According to the method, a terminal device determines that a first cell as a camped cell of the terminal device; and then determines that the terminal device is in a target environment. The terminal device further obtains a signal strength of the first cell and performs a measurement on a second cell when the signal strength of the first cell is less than a first threshold and greater than a second threshold. The second cell determined by the terminal device based on the target environment. The terminal device switches the camped cell of the terminal device from the first cell to the second cell when a measurement result of the second cell meets a handover condition.
MEASUREMENT CONFIGURATION METHOD, TERMINAL, AND NETWORK SIDE DEVICE
A measurement configuration method, a terminal, and a network side device are provided. The measurement configuration method is performed by the terminal and includes: receiving indication information transmitted by a first network side device, where the indication information is used to indicate a signal that changes in a target cell; and performing measurement or synchronization based on the signal that changes, where the target cell includes a serving cell or a neighboring cell, and the signal that changes includes at least one of a reference signal or a synchronization signal.
Multi-stage handover
Systems and methods for enabling a handover decision are disclosed. In one embodiment, a method is disclosed comprising configuring a UE with a first offset and a second offset, the second offset greater than the first offset; instructing the UE to enter a handover decision state upon receiving a first measurement report from a UE indicating that a neighbor cell has a better received signal strength than the serving cell by the first offset; instructing the UE to send periodic measurement reports with signal strength of the serving cell and the neighbor cell; delaying handover decision by remaining in the handover decision state until receiving a second measurement report from the UE; and instructing the UE to hand over to the neighbor cell when the neighbor cell has a better received signal strength than the serving cell than the second offset.
Measurement report triggering method and apparatus
Embodiments of the application provide a communications method and apparatus. A target cell is determined based on measurement results of N measured cells and a preset value when there is a first cell satisfying a report trigger condition. A measurement result of the target cell is sent to a base station. A terminal may not only send the measurement result of the cell satisfying the trigger condition to the base station, but also send a measurement result of another cell to the base station. In this way, a quantity of cells that can be selected during determining of handover can be increased, to help the base station select a suitable cell for the terminal.
TECHNIQUES FOR MAINTAINING MULTICAST AND/OR BROADCAST SERVICE WIRELESS COMMUNICATIONS
Aspects described herein relate to communicating with one or more cells for receiving a multicast and/or broadcast service (MBS), and providing MBS continuity in device mobility scenarios. In an aspect, one or more cells for reselection from a current cell can be detected, where the current cell supports a UE interested MBS. The one or more cells can be evaluated for reselection based at least in part on whether the one or more cells support the UE interested MBS to determine a target cell for reselection. Cell reselection can be performed to the target cell.
INFORMATION SENDING METHOD, BASE STATION SWITCHING METHOD, INFORMATION RECEPTION METHOD AND APPARATUS
The present disclosure provides an information sending method, including in response to determining that a second SIM card in a connected state satisfies a handover condition for handing over the second SIM card from a first base station to a second base station, sending context information of a first SIM card to the first base station through the second SIM card, wherein the first SIM card is in an inactive state. According to the technical solutions of the present disclosure, the first SIM card does not need to send the context information to the second base station separately, nor temporarily adjust its state, thus the times of communication between the terminal and the base station are reduced, the communication progress is simplified and the communication resources are saved.
Reconfiguration Procedure in a Wireless Communication Network
A network node (1700) configured to operate as a source network node (32) of a reconfiguration procedure transmits signaling to a target network node (34) of the reconfiguration procedure. The signaling indicates (i) whether or not the target network node (34) is to provide feedback information (44) to the source network node (32) and/or (ii) which one or more types of feedback information (44) the target network node (34) is to provide to the source network node (32). Based on the received feedback information (44), the network node may train a model to predict predicted information, predict the predicted information using the model, and make a decision based on the predicted information.
UE FALLBACK FROM DUAL-ACTIVE PROTOCOL STACK TO CONDITIONAL HANDOVER
A method and apparatus may include receiving, by a user equipment from a source cell, a first configuration configured for conditional handover and dual active protocol stack handover with a reduced target cell configuration, and a second configuration configured for conditional handover only. The method may further include determining, by the user equipment, the availability of at least one radio link associated with the source cell. The method may further include performing, by the user equipment, a conditional handover procedure according to at least one of the received configurations based upon the determination.
