Apparatus and methods are provided for cooperative communication for sidelink relay. In one embodiment, a plurality of sidelink relay paths are configured for an end-to-end communication path between two end nodes, a source node and a destination node, with one or more relay UEs. The source node or one or more intermediate relay node(s) within the sidelink relay path performs packet, segment, or radio bearer based cooperative communication at one protocol layer. The cooperative communication includes data duplication and data split depending on one or more factors. In one embodiment, the cooperative communication is supported by the weigh value transmission from the sender to the receiver node within the sidelink relay network. The weight value is statically configured or dynamically carried by an ACP control PDU. In one embodiment, the cooperative communication is supported by the redundant packets or segments removal at the intermediate relay node(s), and/or destination node.

Methods, systems, and devices for sidelink wireless communications are described in which multiple resource pools are available for sidelink communications. Each resource pool may include a set of frequency domain resources, a set of time domain resources, and one or more subsets of available spatial resources. A transmitting user equipment (UE) may select a first spatial resource of a first resource pool for the sidelink communication, and determine a demodulation reference signal (DMRS) pattern for the sidelink communications based on the selected first spatial resource of the first resource pool. The transmitting UE may then transmit the sidelink communication and DMRS to a receiving UE using the first spatial resource of the first resource pool. The receiving UE may identify the DMRS and use the DMRS to demodulate the sidelink communication of the transmitting UE.

Facilitating sidelink-based relaying and multi-connectivity in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can comprise facilitating, by a first communications device comprising a memory and a processor, an establishment of multiple-connectivity for communication links between a second communications device and a third communications device. Facilitating the establishment of the multiple-connectivity for the communication links can comprise facilitating establishing a communication link between the second communications device and the third communications device. Facilitating the establishment of the multiple-connectivity for the communication links also can comprise facilitating establishing a first communication relay link between the second communications device and the first communications device and a second communication relay link between the first communications device and the third communications device.

A method by a first base station comprises receiving a message including information related to a sum of traffic loads of user equipment and information related to a location of a second base station from second base stations, identifying a sum of traffic loads transmitted from the second base stations, to the UEs, identifying whether the identified sum of the traffic loads is larger than a sum of data rates for the corresponding UEs of the corresponding second base stations located in the specific first area, when the identified sum of the traffic loads is larger than the sum of the data rates, identifying a specific UE to be operated as a second base station among the corresponding UEs located in the specific first area, and transmitting information indicating that the specific UE is to operate as the second base station to the specific UE.

Techniques described herein improve direct communication channel reliability in a vehicle-to-everything (V2X) communication. The techniques include a (wireless communication) device that uses a first licensed band to perform a cellular network communication through a first interface (e.g., Uu), and further uses a shared spectrum to perform a V2X communication through a direct communication channel interface. The device then monitors and compares a bandwidth requirement of the V2X communication with a bandwidth of the shared spectrum. In response to the bandwidth that is less than the bandwidth requirement, the device selects a second licensed band that includes a bandwidth that is at least equal to the bandwidth requirement. Further, the selected second licensed band is different from the first licensed band to avoid channel interference. In other embodiments, the device uses the licensed band to directly establish the V2X communication.

An industrial wireless instruments network connects a plurality of industrial wireless instruments to a monitoring and control application. The network employs wireless relay nodes that operate as dedicated proxies for the wireless instruments to which they are connected in the network. In some embodiments, the wireless relay nodes are Bluetooth Low Energy (BLE) devices that are capable of implementing Bluetooth version 4.0 or higher. In some embodiments, the relay nodes are deployed in a multi-hop arrangement to extend the range between the wireless instruments and the monitoring and control application. In some embodiments, the relay nodes are deployed in parallel so as to provide easy scale out, redundancy, and load-balancing. Such an arrangement has several advantages over conventional solutions like mesh networks.

Disclosed are a data transmission method and apparatus, a non-transitory computer readable storage medium, and a computing device. The data transmission method is executed by a computing device, and includes: receiving first packets transmitted by a first device over multiple data channels; parsing the first packets to obtain address information of the first device, and performing aggregation on the first packets according to headers of the first packets, to obtain second packets, the designated address information comprising a virtual port assigned to the first device and associated with the address information of the first device; replacing source address information of the second packets with designated address information, to obtain third packets; and transmitting the third packets to a second device, the second device being a device that the first device needs to access.

Methods and apparatuses for handling invalid Radio Resource Control (RRC) message for sidelink communication in a wireless communication system are disclosed herein. In one method, the first User Equipment (UE) establishes a PC5 unicast link or a PC5-RRC connection with a second UE, wherein the PC5 unicast link or the PC5-RRC connection is associated with a destination identity of the second UE. The first UE transmits a Sidelink User Equipment (UE) Information message to a network node to request a sidelink configuration for a sidelink Quality of Service (QoS) flow, wherein the Sidelink UE Information message includes the destination identity of the second UE and an identity of the sidelink QoS flow. The first UE receives a RRC Reconfiguration message from the network node, wherein the RRC Reconfiguration message includes the sidelink configuration. The first UE transmits a RRC message to the network node to indicate a configuration failure if the first UE is unable to comply with the sidelink configuration included in the RRC Reconfiguration message.

Methods, systems, and devices for wireless communications are described. A first user equipment (UE), such as a pedestrian UE, may perform a discovery procedure with a second UE in a vehicle-to-everything (V2X) wireless communications environment that includes multiple other UEs in addition to the first UE and the second UE. The second UE may, for example, be a roadside UE configured to aggregate V2X messages for the first UE. The first UE may determine, based on performing the discovery procedure, a schedule for the first UE to use to receive bundled V2X messages from the second UE. The first UE may receive, from the second UE based on the determined schedule, a message indicating bundled information from multiple V2X messages received at the second UE from the multiple UEs.

The method includes: obtaining first network status information of a first network device; obtaining information indicating a network status of a second network device; obtaining a to-be-effective first mobility load balancing MLB policy based on the first network status information and the information indicating a network status of the second network device; and sending the first MLB policy to the second network device.
