According to one aspect of the present invention, a user terminal includes a receiving section that receives a plurality of synchronization signal blocks, transmitted in each of a plurality of frequency bands in a specific frequency band, and a control section that controls transmission and/or receipt to use the specific frequency band, based on at least one of the plurality of synchronization signal blocks.

Abstract: Methods for transporting a media call between an IMS server and a User Equipment (UE) and of handing over the media call between a cellular network and a WLAN are provided. In an embodiment, the media call data and signaling are split such that the data is transported over the WLAN and the signaling is transported over the cellular network. In another embodiment, handover latency is reduced by using a dual registration process that registers the UE with an IMS server using both a WLAN-based contact and a cellular network-based contact. The media call can then be carried over the WLAN and/or the cellular network and can be handed over seamlessly from one to the other within minimal signaling.

Abstract: A user equipment (UE) is provided. The UE supports D2D wireless communication and includes a communication module configured to communicate with at least one different UE, a non-transitory computer readable memory storage configured to store instructions, and at least one processor electrically connected to the communication module and the memory storage. The instructions, when executed by the UE, cause the processor to check whether an available first synchronization signal is detected, determine whether to operate as a first synchronization reference UE based on whether the first synchronization signal is detected, and transmit first system information comprising an intensity of transmission power and a second synchronization signal comprising a first synchronization identifier if the UE is determined to operate as the first synchronization reference UE.

Abstract: Source and target service nodes and methods are described for transferring a service session for a wireless device from the source node to the target node when a service application is executed in the source node for the wireless device by the service session. In particular, the amount of application data to be transferred from the source node to the target node for a wireless device that is handed over from a first base station to a second base station can be reduced by truncating the application data by an amount corresponding to the data pending in a downlink buffer at the first base station. Thereby, the target node is able to recreate the complete application buffer from the truncated application data and data from the downlink buffer, the latter data being transferred from the first base station (206) to the second base station (208), according to a handover procedure.

Abstract: Provided are a communication method using a frequency band of a base station in a wireless communication system, and a device using the method. The method divides an entire frequency band so as to determine a plurality of subbands and transmits a transport block in at least one subband among the plurality of subbands, wherein the size of the transport block has a maximum value set so as to correspond to the entire frequency band size or the subband size.

Abstract: A controller receives an access request message of a to-be-served flow that is sent by a network device. The access request message includes an identifier of the to-be-served flow and an identifier of a terminal that sends the to-be-served flow. The controller determines service level information of the to-be-served flow based on the identifier of the terminal and the identifier of the to-be-served flow. The controller determines a transmission path of the to-be-served flow and a transmission path of a being-served flow based on the service level information of the to-be-served flow and service level information of the being-served flow. The controller publishes the transmission path of the to-be-served flow and the transmission path of the being-served flow to the network device.

Abstract: In one embodiment, a copy of an original packet of a traffic flow is created at an ingress leaf node of a cloud switch. The ingress leaf node forwards the original packet along a less-specific path through the cloud switch, the less-specific path based on a domain index of an egress domain for the original packet. The copy of the original packet is modified to create a more specific path learn request packet. The ingress leaf node forwards the more specific path learn request packet along the less-specific path through the cloud switch. The ingress leaf node received back a more specific path learn request reply packet that includes an indication of a fabric system port. The ingress leaf node then programs a forwarding table based on the indication of the fabric system port, to have subsequent packets of the traffic flow forwarded along a more-specific path.

The method includes: calculating a first duration based on at least one to-be-sent data flow and a first time interval, where the first time interval is a preset value, and different data flows in the at least one to-be-sent data flow have different 5-tuples; and sending a first data flow, where the first data flow belongs to the at least one to-be-sent data flow; where a first set of packets of the first data flow are sent in a first time period, a second set of packets of the first data flow are sent in a second time period following a second time interval, a duration of the first time period and a duration of the second time period are equal to the first duration, and the second time interval is greater than or equal to the first time interval.

Abstract: A relay node supporting mobile terminal (MT) functionality and distributed unit (DU) functionality may receive a timing advance (TA) value for uplink synchronization associated with a timing alignment timer from a parent node. In some cases, the timing alignment timer may expire prior to the relay node receiving a next TA value. Upon expiration of the timing alignment timer, the relay node may initiate a second timer (e.g., a transition timer) associated with the transitioning of a DU entity of the relay node to a DU transition state. The DU transition state is associated with certain DU behavior for serving child nodes while the transition timer is active. Configuration of the DU transition state may be identified by the relay node, or received from a parent node. In cases where the transition timer expires prior to receiving a next TA value, the DU may declare a loss of uplink synchronization.

Abstract: Disclosed in the present invention are a method and a device for allocating a continuous scheduling resource and transmitting data using the continuous scheduling resource, comprising: generating a continuous scheduling resource allocation table for a terminal, wherein the continuous scheduling resource allocation table includes mapping relationships between each continuous scheduling resource and a transmission time interval length and/or a channel condition; sending the continuous scheduling resource allocation table to the terminal. When transmitting data by using continuous scheduling resources, determining the continuous scheduling resource allocation table; after the transmission time interval length and/or channel condition at the time of transmission is determined, determining the continuous scheduling resource according to the mapping relationships in the continuous scheduling resource allocation table; transmitting data using the continuous scheduling resource.

Abstract: Multi-band Wake-up (MWU) signal transmission and detection is disclosed. A transmitter determines a MWU signal that indicates availability of one or more sub-bands to a first user in a serving cell, and transmits the MWU signal for the one or more sub-bands in the serving cell. A clear channel assessment (CCA) status on the one or more sub-bands that are available to the first user is carried by the payload of MWU signals. The MWU signal includes a first user identifier that identifies the first user as a targeted receiver of the MWU signal. The first user has priority over a second user to utilize the one or more sub-bands. Correspondingly, a receiver receives a MWU signal for one or more sub-bands in the serving cell, decodes a payload of the MWU signal, and determines availability of the one or more sub-bands to the first user based on the payload of the MWU signal.

Abstract: Connection control circuitry is provided for a User Equipment (UE) configurable to offload communication of packet data from a cellular radio-access network comprising a Trusted Wireless Local Access Network (TWLAN) and a Trusted Wireless Access Gateway (TWAG) with IP Address preservation. The connection control circuitry has a connection requesting module configured to send a distinguishable-connection establishment message to the TWAG, requesting setup of a TWAG-routed data connection comprising at least one of a Packet Data Network (PDN) connection and a Non-Seamless Wireless Offload (NSWO) connection. A unique virtual gateway interface address is used to identify a point-to-point link between the UE and the TWAG. This allows the TWAG to distinguish between multiple substantially simultaneous point-to-point links which support multiple substantially simultaneous packet data connections. Other embodiments may be described and claimed.

Abstract: A system described herein may provide a technique for selecting and configuring a capture component and a filtering and analysis component for traffic capture in a manner that suitably accounts for Service Level Agreements (“SLAs”) of traffic to be captured. A traffic capture request may indicate one or more SLAs and/or other attributes, and an orchestration system may identify a network function (such as a User Plane Function (“UPF”) of a wireless network) that handles traffic that includes the requested traffic and instantiate the capture component at a node that implements the network function. The orchestration system may select a node, from a cluster of nodes, that is able to filter and analyze the traffic in an expedient manner in accordance with SLA(s) associated with the requested traffic, and install the filtering and analysis component at the selected node.

Abstract: The described technology is generally directed towards lossless delivery of data when there are route changes, e.g., in an integrated access and backhaul (IAB) multi-hop relay network. When a route changes is to occur, the last unchanged node in a multiple hop route preserves the data (e.g., copies unacknowledged and unsent PDCP PDUs from the protocol stack corresponding to the radio link control layer of the failed relay hop, and populates a replacement protocol stack for the node in the new route with the preserved data. Also described is pre-emptive detection of link failure, which triggers a route change based on monitoring retransmissions to detect a deteriorating link, which can occur before complete link communication failure.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include identifying a reference number of tones for an overhead channel of a transport block and segmenting the transport block into a code block based at least in part on the reference number of tones for the overhead channel. In some examples, a code block indicator or the reference number of tones may be transmitted on a control channel. Another method may include receiving a code block size indicator associated with a code block of a transport block, decoding the code block based at least in part on the code block size indicator and assembling the transport block based at least in part on the decoded code block. In some examples, the code block size indicator may be received using a control channel.

Abstract: This disclosure generally relates to downlink transmission scheduling for D2D UE based on subframe pattern. In one embodiment, the D2D UE may provide the BS with information on a pattern of the D2D reception subframes that indicates the usage of at least some of the D2D reception subframes. From the pattern, the BS may determine one or more D2D reception subframes in which the UE wants to monitor the D2D reception and/or the cellular reception. Then the BS may avoid scheduling the downlink transmission in the subframes in which the UE monitors the D2D reception. In the other D2D reception subframes, the downlink transmission can be scheduled. In this way, the UE can properly switch between the D2D reception and cellular reception, without any conflicts or downlink resource waste.

Abstract: A terminal device, for example a 3GPP Proximity Services (ProSe)-enabled user equipment, obtains imprecise location information relating to a location of the terminal device, and transmits a proximity service discovery message, wherein the discovery message includes the imprecise location information. A second terminal device, again for example a 3GPP Proximity Services (ProSe)-enabled user equipment, receives a proximity service discovery message containing location information. The second terminal device obtains location information relating to its location, and calculates a distance from the location indicated by the location information in the received discovery message to its location. The second terminal device acts on the received discovery message only if the calculated distance is less than a predetermined distance.

Abstract: transmissions outside a transmission opportunity (TxOP) is disclosed. The UE can process an uplink (UL) opportunity received from an eNodeB during a defined transmission opportunity (TxOP). The UL opportunity can schedule UL information to be transmitted from the UE on one or more UL subframes that are outside the defined TxOP. The UE can initiate a listen-before-talk (LBT) procedure to be performed before the UL information is transmitted from the UE on the one or more UL subframes that are outside the defined TxOP. The UE can process the UL information for transmission to the eNodeB on the one or more UL subframes located outside the defined TxOP.
