A method performed by a network node for transmission of a Packet Data Convergence Protocol, PDCP, Protocol Data Unit, PDU, to a wireless communications device is provided. The network node and the wireless communications device operate in a wireless communications network. The network node arranges (505) a number of PDCP PDUs in a numerical order based on their respective PDCP Sequence Number, SN. The number of PDCP PDUs is taken from a first set of PDCP PDUs comprising one or more first time transmitted PDCP PDUs and from a second set of PDCP PDUs comprising one or more retransmitted PDCP PDUs. The one or more first time transmitted PDCP PDUs and the one or more retransmitted PDCP PDUs are received from a controlling node. The network node transmits (506) the number of the PDCP PDUs in the numerical order to the wireless communications device 120.

Aspects relate to measurement and event reporting from a distributed unit (DU) of a disaggregated base station to a central unit (CU) of the disaggregated base station. The CU can configure the DU with a measurement configuration associated with at least one value to be obtained by the DU and a reporting configuration for reporting the at least one value to the CU. The measurement reports can be sent by DU periodically or the measurement reports can be event-triggered based on the reporting configuration. In addition, the measurement reports can be UE-specific or DU/cell-specific. The measurement reports may include random access channel (RACH) reports, uplink measurement reports, radio link protocol (RLC) reports, medium access control (MAC) protocol reports, and other types of measurement or event-based reports.

Mechanisms and methods are provided for improving wireless audio transmission and synchronization for multi-channel Bluetooth® Low Energy (BLE) systems. In various embodiments, mechanisms and methods may include generating transmissions having a plurality of Protocol Data Units (PDUs) to BLE-compliant slave devices. The plurality of PDUs may be stored in a buffer. When an error is determined to have occurred in transmitting one of the PDUs, a re-transmission to the slave device may be generated, which may include the PDU in error and any subsequent PDUs of the plurality of PDUs.

A platform for facilitating development of intelligence in an Industrial Internet of Things (IIoT) system generally includes a plurality of distinct data-handling layers having an industrial monitoring systems layer that collects data from or about a plurality of industrial entities in an industrial environment; an industrial entity-oriented data storage systems layer that stores the data collected by the industrial monitoring systems layer; and an adaptive intelligent systems layer that facilitates the coordinated development and deployment of intelligent systems in the IIoT system; wherein the adaptive intelligent systems layer includes an adaptive edge compute management system that adaptively manages edge computation, storage, and processing in the IIoT system.

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.

The method is used for detection and/or removal of errors in transmission systems which comprise a transmitter unit and at least one receiver unit. The transmitter unit transmits to the receiver unit on a semi-persistent transmission resource which provides an adjustable frequency range and an adjustable time period. Furthermore, the self-repeating, semi-persistent transmission resource repeating with the period T.sub.SPS is rigidly assigned to the receiver unit. Following this, at least one but not all of the HARQ process numbers available for the self-repeating, semi-persistent transmission resource are reserved for the latter.

System and method for improving channel efficiency in a wireless link between an access-point transceiver and a first transceiver. The first transceiver may have a first data throughput rate that is lower than the maximum possible data throughput rate of the wireless link. The first transceiver may include a first receive buffer. An indication of the first data throughput rate and a size of the first receive buffer may be received and stored by the access-point transceiver. A first size of a first data packet for transmission to the first transceiver may be determined by the access-point transceiver based on one or more of the first data throughput rate and/or the size of the first receive buffer. The first data packet of the first size may be transmitted to the first transceiver by the access-point transceiver at a data rate that is higher than the first data throughput rate.

In a broadcast/multicast IP distribution network for reliable transfer of data/media from at least one transmitter to at least one receiver, the network having a system for generic IP error correction of packets sent in a data/media stream, the system comprising: a probe device configured to send packetized data in the data/media stream to one of a plurality of recovery servers, the probe device associated with the at least one transmitter; a detection device for packet loss detection, the detection device associated with the at least one receiver, the detection device adapted to send a missing packet request to the plurality of recover servers upon detecting a missing packet; and a message communication between the detection device and the plurality of recovery servers, the message communication including packet loss event notification messages with respective messages indicative of at least one missing packet in the data/media stream that did not reach the detection device; wherein the data/media stream is buffered in the plurality of recovery servers, the recovery servers available for a recovery process.

A method and apparatus for communicating streaming data in a Bluetooth-based wireless communication system is provided. An electronic device according to the present disclosure includes a communication interface configured to perform wireless Bluetooth communication with an external electronic device and a controller configured to control the communication interface, in which the controller is further configured to detect a communication state using a first packet data configuration and communicate with the external electronic device by using a second packet data configuration that is different from the first packet data configuration, based on the communication state.

Methods and apparatuses are provided for performing communication in a wireless communication system is provided. A number of hybrid automatic repeat request (HARQ) processes is set as N. The N is a natural number, one value within a maximum value, 16, and set based on a configuration of a base station (BS). Downlink control information (DCI) is received including a 1-bit HARQ-acknowledgment (HARQ-ACK) feedback request for all of N HARQ processes. HARQ-ACK information associated with all of the N HARQ processes is identified, based on the received DCI. A number of bits for the HARQ-ACK information is defined based on xN by the configuration, and the x is a natural number. The HARQ-ACK information is transmitted to the BS.
