A target node includes an S1 interface which includes an interface between the target node and a gateway, an X2 interface which includes an interface between a source node and the target node, and a transceiver which receives data from the S1 interface and data from the X2 interface. The transceiver sends the data from the X2 interface before sending the data from the S1 interface to a mobile device after the mobile device completes a handover from the source node to the target node.

A first base station receives from a second base station, a handover request message for a wireless device. The handover request message comprises: one or more temporary mobile group identities (TMGIs) of one or more multimedia broadcast multicast service (MBMS) services that the wireless device is receiving or interested to receive; and at least one bearer identifier of at least one bearer for the wireless device. The first base station sends to the second base station, a handover request acknowledge message in response to the handover request message. The handover request acknowledge message indicates accepting at least one of the at least one bearer. The first base station transmits transport blocks comprising: MBMS transport blocks providing at least one of the one or more MBMS services to the wireless device; and data transport blocks of the at least one of the at least one bearer.

A method and a terrestrial base station for receiving an uplink signal. The terrestrial base station is configured to: receive a preamble corresponding to an orthogonal pseudo-noise (PN) sequence of a plurality of the orthogonal PN sequences from an onboard base station in a train; recognize identification (ID) of the onboard base station from the preamble, and allocate a temporary network ID and an uplink grant (UL grant) to the onboard base station; and receive the uplink signal transmitted based on the temporary network ID and the UL grant.

The present disclosure provides a handover method for grant-free transmission, a terminal device, and a network device. The handover method includes: sending, by a first network device, a handover request message to a second network device to request to hand over a terminal device from the first network device to the second network device to perform grant-free transmission; receiving, by the first network device, a handover request acknowledgement message sent by the second network device to acknowledge handing over the terminal device from the first network device to the second network device to perform grant-free transmission; and sending, by the first network device, a handover instruction message to the terminal device to instruct the terminal device to transmit a signal to the second network device on a CTU resource in a grant-free transmission mode.

A first base station receives a UE assistance information message from a wireless device. The UE assistance information message comprises traffic pattern parameters for SPS traffic of the wireless device. The traffic pattern parameters comprise: a first traffic periodicity of a first traffic of the one or more SPS traffic; a first timing offset of the first traffic; and a first message size of the first traffic. The first base station sends, to a second base station, a request message for a handover of the wireless device. The request message comprises the traffic pattern parameters. The first base station receives from the second base station, a handover request acknowledge message indicating SPS configuration parameter(s) for SPS radio resources determined based at least on the traffic pattern parameters. The first base station transmits to the wireless device, a handover command message indicating the SPS configuration parameter(s).

In one aspect, a method of wireless communication by a first wireless device includes detecting a near field communication (NFC) read of the first wireless device. The NFC read may be a read initiated by a second wireless device via an NFC interaction between the first wireless device and the second wireless device. The method also includes adjusting at least one Bluetooth paging scan parameter of the first wireless device in response to detecting the NFC read.

Methods and systems are presented for accepting inputs into a vehicle or other conveyance to control functions of the conveyance. A vehicle control system can receive gestures and other inputs. The vehicle control system can also obtain information about the user of the vehicle control system and information about the environment in which the conveyance is operating. Based on the input and the other information, the vehicle control system can modify or improve the performance or execution of user interface and functions of the conveyance. The changes make the user interfaces and/or functions user-friendly and intuitive.

A network node, a network control node and methods therein for achieving load based signaling. The method performed by the network node includes determining a load level out of a set of predefined load levels based on a current load of the network node, where each load level corresponds to an estimated capability of the network node to handle signaling from at least one network control node. The method further includes indicating the determined load level to at least one network control node, thus enabling the at least one network control node to apply a signaling handling scheme towards the network node based on the indicated load level.

An information processing method and a communication node are disclosed. The method configured in a first Device-to-Device (D2D) User Equipment (UE) includes: receiving bearer control information sent by a first evolved Node B (eNB); and changing to a second access node according to the bearer control information for communication data transmission, wherein the first eNB is a first access node or the second access node, and the second access node is the first eNB or a D2D relay node. Also disclosed is a computer storage medium.

A data transmission control method, apparatus and system are provided. A radio communication node receives a data packet sent by a base station, where the data packet is generated by using a Packet Data Convergence Protocol protocol data unit PDCP PDU of the base station. The radio communication node acquires the PDCP PDU, which is used as a Radio Link Control service data unit RLC SDU, in the data packet. The radio communication node sends data generated by using the RLC SDU to a user equipment, where a user plane connection is established between the radio communication node and the user equipment, and a control plane connection is established between the base station and the user equipment.
