A method of a Bluetooth controller device includes: providing multiple Bluetooth controllers to use a same configuration setting of a link control protocol sent from the host device to respectively control the multiple Bluetooth radio circuits to transmit and receive Bluetooth packets, clocks of the multiple Bluetooth controllers being synchronized with each other; and configuring the multiple Bluetooth controllers as central roles respectively to negotiate with corresponding peer Bluetooth controllers, to be used as peripheral roles associated with the central roles, by respectively ignoring or rejecting at least request from the corresponding peer Bluetooth controllers, to make a packet transmission time of a first Bluetooth radio circuit in the multiple Bluetooth radio circuits be separated from a packet reception time of a second Bluetooth radio circuit in the multiple Bluetooth radio circuits.

The present disclosure generally relates to an asymmetric radio link control (RLC) protocol. One aspect of the present disclosure relates to a method that includes: receiving control signaling that configures at least one uplink RLC transmission parameter and at least one downlink RLC reception parameter for the asymmetric RLC protocol; transmitting an uplink packet using the at least one uplink RLC transmission parameter configured for the asymmetric RLC protocol; and receiving a downlink packet using the at least one downlink RLC reception parameter configured for the asymmetric RLC protocol.

A computer-implemented method method, performed by a transmitting node (111) operating in a wireless communications network (100). The transmitting node (111) sends (207), to a receiving node (112) operating in the wireless communication network (100), an RLC Control PDU comprising one or more of: a) a PDCP Control PDU and first information indicating that the one or more data units have been discarded by a PDCP entity (122) of the transmitting node (111) and b) second information indicating that one or more data units have been discarded by an RLC entity (121) of the transmitting node (111).

The present invention discloses a Bluetooth controller device and a method thereof, the method comprising: providing a plurality of Bluetooth controllers to respectively control a plurality of Bluetooth radio circuits to transmit and receive Bluetooth packets using the same configuration setting of a link control protocol transmitted from a host device, the clocks of the plurality of Bluetooth controllers being synchronized with each other; and respectively configuring the plurality of Bluetooth controllers as a central role, negotiating with a corresponding peer-to-peer Bluetooth controller as a peripheral role associated with the central role, and providing a plurality of Bluetooth controllers to the corresponding peer-to-peer Bluetooth controller by respectively ignoring or rejecting at least a request from the corresponding peer-to-peer Bluetooth controller as a peripheral role associated with the central role. A packet transmission time of a first Bluetooth radio circuit of the plurality of Bluetooth radio circuits is separated from a packet reception time of a second Bluetooth radio circuit of the plurality of Bluetooth radio circuits.

The invention provides a configuration-free fault-tolerant reconstruction and fault recording method for a synchronous distributed collaborative network, which comprises the following steps: determining whether an overtime event occurs or not according to a period timeout number and synchronous distributed collaborative network data, and generating an autonomous fault-tolerant reconstruction signal when the overtime event occurs; responding to the autonomous fault-tolerant reconstruction signal, controlling to open all physical ports and send a link control protocol frame to the network, and starting autonomous fault-tolerant reconstruction; according to the returned link control protocol frame, the state of an equipment port is configured, the autonomous fault-tolerant reconstruction process is completed, and the autonomous fault-tolerant reconstruction process is realized based on the FPGA; and a link control protocol frame generated in the autonomous fault-tolerant reconstruction process is received and analyzed, the content of the protocol frame is extracted, the network level is restored according to the content of the protocol frame, the network topology is reconstructed, and a log file is generated. And when the working state of the port is abnormal, the reconstruction of the equipment port is easy to realize through network reconstruction, and the port reconstruction does not need manual configuration, so that the development workload can be greatly reduced.

In one embodiment, a method is provided performed by a first distributed unit (DU) providing a primary cell (PCell). The method may include: receiving a request message for downlink data from a second DU via a communication interface between the first DU and a second DU providing a secondary cell (SCell); and sending a response message to the second DU via the communication interface as a response to the request message. The request message may include a user equipment (UE) identifier (ID), a bearer ID, information about the amount of downlink data, and information about the data type. The response message may include a UE ID, a bearer ID, an index indicating the SCell, and the downlink data. The data type may indicate one of several types, including a first type for Radio Link Control (RLC) Protocol Data Units (PDUs) and a second type for Media Access Control (MAC) PDUs.

A method performed by a processing system including at least one processor includes identifying a service that is to transmit data to a user endpoint device over a radio access network, determining a length for a radio link control sequence number of a radio link control protocol data unit associated with the service, where the length is determined based on at least one of: a number of component carriers of a carrier aggregation scheme assigned to the user endpoint device, a radio condition of the user endpoint device, or a configuration of the radio access network, and configuring the radio link control protocol data unit with the length for the radio link control sequence number that is determined.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a radio link control (RLC) protocol data unit (PDU) within a receive window. Additionally, the UE may receive an uplink grant indicating a set of resources. Based on the set of resources, the UE may transmit a STATUS PDU including a single field indicating a sequence number (SN) of a first PDU received by the UE within a receive window but not successfully decoded. Alternatively, the UE may transmit the STATUS PDU segment based on which PDUs the UE receives and the number of resources in the uplink grant. In some cases, a UE may transmit a STATUS PDU that includes a first field indicating an SN of a first PDU received by the UE within a receive window but not successfully decoded, and one or more offset fields indicating an SN of a corresponding PDU following the first PDU.
