A method for performing a wideband short-range wireless communication which may use a directional antenna in a millimeter wave band, and the method for wideband short-range wireless communication according to an embodiment may determine a change of a relay operation type based on a link quality between a source node and a relay node, a link quality between the relay node and the destination node, and a link quality between the source node and the destination node, transmit a relay operation change (ROC) request message in response to a determination of the change of the relay operation type, and receive an ROC response message corresponding to the ROC request message.

A method of processing state information relating to user equipment in a communications system comprising a radio access network, the method comprising: maintaining current state information relating to the user equipment; and on the basis of a change of connection of the user equipment from a first cell to a second cell: transmitting a current value associated with a given state information part to the target radio access node in response to detecting at least one of one or more predetermined triggers that indicate that the target radio access node may not have received the current value from the source radio access node; or relying on the target radio access node having received the current value from the source radio access node if said at least one of said one or more predetermined triggers is not detected.

Aspects of the disclosure provide a handoff procedure for a satellite communication system such as a broadband low-Earth orbit (LEO) satellite communication system. A gateway and a user terminal (UT) coordinate and schedule a satellite-to-satellite handoff in such a way that there are no messaging round-trip delays between the last return service link (RSL) packet transmitted from the user terminal to the source satellite and the first RSL packet transmitted from the user terminal to the target satellite. Therefore, an outage on the return link (from the user terminal to the gateway) can be limited to the actual time for moving the antenna feed from the source satellite to the target satellite. Furthermore, an outage on the forward link (from the gateway to the user terminal) can be limited to a single round-trip delay in addition to the time for moving the antenna feed.

The application provides a handover processing method and a base station. The method includes: receiving a handover request message sent by a source base station or a core network node; sending a first message, according to the handover request message, to a second target base station to notify the second target base station that a handover of part or all of a service of a user equipment to the second target base station is to be performed; and sending a handover request acknowledge message to the source base station or the core network node to notify the source base station or the core network node to hand over the user equipment to at least one target cell of the first target base station and/or at least one target cell of the second target base station. The present application realizes a multi-cell handover.

Provided are a communication method and an apparatus for a multimedia broadcast multicast service (MBMS) in a wireless communication system. A wireless device determines, from among a plurality of subframes, a shared multimedia broadcast multicast service single frequency network (MBSFN) subframe utilized in a plurality of MBSFN regions, and receives a shared MBSFN reference signal (RS) from within the shared MBSFN subframe.

A wireless device and a method therein for assisting in precoder selection for wireless communication with a Radio Node (RN), and a RN for performing precoder selection for wireless communication with a wireless device. The wireless device is configured with a set of precoders. The wireless device determines a subset of precoders out of the set of precoders; and transmits, to the RN, at least one Sounding Reference Signal (SRS) precoded with a respective at least one precoder comprised in the subset. The RN receives, from the wireless device, at least one SRS precoded with a respective at least one precoder comprised in a subset of precoders; and transmits, to the wireless device, a signal indicative of a selected precoder to be used for a transmission to the RN, wherein the selected precoder is indirectly selected based on the received at least one SRS.

The present subject matter describes performing radio resource management (RRM) measurements by a WTRU in a 3GPP networks. The method comprise defining at-least one of: a) a channel condition threshold, b) a WTRU mobility threshold, and c) a measurement-reliability threshold. A first sub-set of reference-signal samples are measured out of a set of reference-signal samples based on sensing at least one of current channel conditions and mobility-conditions. A reliability-parameter associated with the first sub-set of measured samples is checked. Finally, network-measurement operation is concluded in case of the reliability-parameter being in accordance with the pre-defined reliability-thresholds.

A method for a user equipment (UE) is provided. The method includes the UE maintaining a Radio Resource Control (RRC) connection with a first base station (BS) of a first network while receiving transmissions from a second BS of a second network during at least one time period specified in a switch gap configuration. The UE receives an RRC reconfiguration message from the first BS that includes a first command and a second command. The first command instructs the UE to begin a handover procedure from the first BS to a third BS. The second command controls usage of the switch gap configuration by the UE following a failure of the handover procedure. The UE initiates the handover procedure according to the first command. The UE may suspend reception of transmissions from the second BS following reestablishment of the RRC connection after the handover failure based on the second command.

A method for time synchronization determination and related products are provided. The method includes the following. A terminal device receives a handover command from a first device, where the first device is a device currently accessed by the terminal device, and the handover command indicates that the terminal device hands over from the first device to a second device. The terminal device obtains and determines time synchronization information of the second device.
