Apparatus and methods are provided for path switch with service continuity for the UE from the indirect relay link to direct cell link or vice versa. In one novel aspect, the UE is configured with measurement report configuration, which includes triggering event for sending the measurement report. The network sends path switch command to the UE to initiate the path switch based on the measurement report. The UE path switch includes intra-gNB and inter-gNB path switch between the indirect relay link and the direct cellular link. The triggering events are a measurement of the target direct Uu link is an offset better than a measurement of the serving sidelink for a indirect link to direct link switch and a measurement of the PC5 link is better than a predefined threshold for direct link to indirect link switch.

Methods and apparatus of path switch based service continuity for ue-to- network relay

Apparatus and methods are provided for sidelink relay-based UE-to-network communication. The disclosure describes the relay UE performing delayed relay forwarding upon determining the remote UE is in the DRX cycle based on the PC5 configuration. The relay UE buffers the relay traffic and/or sends a suspending indication to the base station to request the base station to suspend the relay traffic to the remote UE. The disclosure describes the relay UE monitoring paging occasions configured for itself and receives paging message from the network intended for the remote UE in one non-connected RRC state. The relay UE sends a PC5 paging message to the remote UE that is in the non-connected RRC state through the established SL based on the received paging message. The disclosure describes the network storing the SL association between the relay UE and the remote UE to the network.

Methods and apparatus of sidelink relay based data communication

Apparatus and methods are provided for L2-based sidelink relay for packet routing. In novel aspect, the L2-based sidelink relay for packet routing is configured based on interest indications from one or more candidate UEs and corresponding UE report from candidate UEs. In one embodiment, the UE report is received from an Uu interface RRC message or an RRC message forwarded through an Xn interface from a serving gNB. The L2 relay configuration includes one or more elements comprising an adaptation layer address of nodes in the relay path, and a packet routing table. The adaption layer is between an RRC layer and a PDCP layer. The packet routing table includes one or more elements including adaptation layer addresses, a relay path ID, and a next hop address. In one embodiment, the relay path includes one or more relay hops.

Packet routing for layer-2-based sidelink relay

A data packet, that is to be transmitted in a dual connectivity (DC) or carrier aggregation (CA) based communications system, may include an indication to indicate whether the data packet is configured to be transmitted in a first frequency of a first carrier or a second frequency of a second carrier, and be transmitted, by a communication device, in the first frequency or the second frequency based on the indication. A data packet in the communications system may also be transmitted first in a first frequency higher than a second frequency, and then be retransmitted in the second frequency upon transmission failure of the data packet in the first frequency.

Method and apparatus for service continuity across LF and mmWave

A method for operating a user equipment (UE) includes detecting an occurrence of an overheating condition in the UE, and based thereon, determining a first set of operating capabilities of the UE from a second set of operating capabilities of the UE, where the first and second set of operating capabilities are associated with a connection between the UE and a network entity, and where the first set of operating capabilities is a reduction in operating capability of the UE when compared to the second set of operating capabilities, triggering a transfer of UE capability information associated with the first set of operating capabilities, and applying, by the UE, the first set of operating capabilities to the connection.

System and method for updating user equipment capability

A method of a relay user equipment (UE) can include receiving, at the relay UE, from a first neighbor UE, a communication request message for establishing a connection between an initiating UE and a target UE, the communication request message including first security-establishment-related information originating from the initiating UE for establishing a security association between the initiating UE and the target UE; modifying the communication request message to add second security-establishment-related information for establishing a security association between the relay UE and a second neighbor UE; and transmitting to the second neighbor UE the modified communication request message that includes the first security-establishment-related information originating from the initiating UE for establishing the security association between the initiating UE and the target UE, and the second security-establishment-related information added by the relay UE for establishing the security association between the relay UE and the second neighbor UE.

Security mechanism for connection establishment over multi-hop sidelinks

A method of connection establishment through a relay UE for a remote UE is proposed. The remote and relay UEs first perform discovery and establish a PC5 radio resource control (PC5-RRC) connection. Upon receiving a request from the remote UE, the relay UE and a serving gNB perform a relaying procedure for establishment of the remote UE's signalling radio bearer 1 (SRB1). The relay UE configures PC5 RLC channels for relaying of SRB1 towards the remote UE. The remote UE then enters an RRC_CONNECTED state. The remote UE and gNB establish security. The gNB configures additional data radio bearers (DRBs) for relaying. The relay UE configures PC5 RLC channels for relaying of the additional DRBs towards the remote UE. The DRBs can then be used for exchange of data between the remote UE and the gNB.

Connection establishment for layer 2 UE-to-network relay

A method and a base station for obtaining a data radio bearer identifier are disclosed. The method includes: the first base station sends a first message to a second base station; receives a second message sent by the second base station; and sends first information to user equipment, where the first message is used to request to add a data radio bearer (DRB), the second message is used to indicate an identifier of at least one DRB, and the first information comprises DRB configuration information including the identifier of the at least one DRB. In this way, the first base station can add the DRB based on a radio resource management policy and a network condition, to reconfigure a mapping relationship between a QoS flow and the DRB, so that setting of the DRB is more flexible and effective.

Method for setting up data radio bearer between base stations in carrier aggregation

The present invention provides a data transmission method, a device, and a system, and relates to the field of communications technologies, to resolve a problem that a base station cannot well identify specific remote UE from which data sent by relay UE comes. The method may include: receiving, by relay UE, data of remote UE, where the data includes a first identifier of the remote UE; determining, by the relay UE, a second identifier of the remote UE based on the first identifier; and sending the data of the remote UE and the second identifier of the remote UE to a base station.

Data transmission method, device, and system

A method executed by a relay UE is provided. The relay UE receives an incoming SideLink (SL) transmission from the first remote UE on the first RLC channel, wherein the first RLC channel is associated with an SL Radio Bearer (SLRB) ID, in which the incoming SL transmission includes the first identifier, which includes the SLRB ID and a first UE ID. The relay UE sends an outgoing SL transmission to a second remote UE on a second RLC channel according to the SLRB ID and the first UE ID.

Apparatuses and methods for SideLink (SL) communication in a User Equipment (UE)-to-UE relaying architecture

Aspects of this disclosure provide techniques for detecting and recovering from beam-failure events. In some embodiments, motion sensor information generated by motion sensors on a UE is used to detect, predict, and/or recover from a beam failure event that results, or would otherwise result, from movement of the UE. The motion sensor information may be used to adjust a current beam direction used by the UE to transmit or receive a signal, or to determine a recommendation for adjusting a current beam direction of the base station. The motion sensor information may be generated by any sensor that detects a movement of the UE, such as a gyroscope, an accelerometer, a magnetometer, a global positioning system (GPS) sensor, a global navigation satellite system (GNSS) sensor, or any other device that detects a change in position/orientation of the UE.

Device/UE-oriented beam recovery and maintenance mechanisms

A method of positioning in a wireless communication system is described. The method can include transmitting from a user equipment (UE) a first message of a communication protocol carried with a first transport protocol, receiving by the UE a second message of the communication protocol carried with a second transport protocol different from the first transport protocol, and transmitting by the UE a third message of the communication protocol using the second transport protocol.

Transport protocol selection between a user equipment and a distributed location function

Mechanism of relay UE discovery and relay UE selection and reselection for remote UE data transmission with a serving base station via relay UE is proposed. A method operable for relay UE selection and reselection of remote UE is provided. The UE considers additional criteria such as relay load other than purely radio signal quality (e.g., RSRP) criteria. The relay load can serve different purpose for relay UE and remote UE. The relay load can be the criteria for UE to become a relay UE or not. It can be the criteria for a remote UE to select another UE as its relay UE.

Relay selection and reselection

Aspects of the disclosure provide a method for observed time difference of arrival (OTDOA) positioning. The method can include receiving from a serving cell of a first network assistance data for measuring time difference of arrival of positioning reference signals (PRSs) received from a plurality of neighboring cells of a second network, receiving from the serving cell a gap pattern for decoding a master information block (MIB) of a first neighboring cell of the plurality of neighboring cells, or a system frame number (SFN) offset of the first neighboring cell, and determining an SFN timing of the first neighboring cell based on the gap pattern for decoding the MIB of the first neighboring cell or the SFN offset of the first neighboring cell.

An apparatus includes transmitting circuitry for transmitting radio signals, receiving circuitry for receiving radio signals and processing circuitry. The processing circuitry is configured to generate data to be transmitted to another apparatus via a first radio link without passing through a base station. The first radio link has a first direction from the apparatus to the other apparatus. Then, the processing circuitry determines a first monitoring configuration associated with the first radio link in the first direction. Then, the transmitting circuitry transmits the data to the other apparatus via the first radio link in the first direction with the first radio link being monitored based on the first monitoring configuration.
