According to embodiments of the present disclosure, service-based retransmission scheme for uplink in NTN has been proposed, which can support multiple retransmission schemes based on service type for uplink. The network device determines different retransmission schemes based on the QoS requirements of the services. The terminal device selects the retransmission scheme for the service. In this way, the QoS of different service and reliability of MAC CE can be guaranteed.

Service based uplink retransmission

Disclosed are methods for adjusting cell coverage of a multimedia broadcast multicast service. An example method () may include transmitting () data of a multimedia broadcast multicast service on a point-to-multipoint channel, monitoring () an uplink channel for information on an abnormal reception of the data, and adjusting () coverage of the point-to-multipoint channel based on the monitoring. Related apparatuses and computer readable media are also disclosed.

Example embodiments of the present disclosure relate to logical channel prioritization. A method includes obtaining an uplink grant from a network device, the uplink grant indicating uplink resources for transmission to the network device and selecting a logical channel prioritization setting from a plurality of logical channel prioritization settings based on a predetermined policy related to the uplink grant, the logical channel prioritization settings defining different sets of prioritization parameters for uplink data in at least one logical channel and uplink control information in occupying the uplink resources. The method further includes generating, based on the logical channel prioritization setting, a packet data unit including at least one of the uplink control information or at least one part of the uplink data for transmission to the network device using the uplink resources. In this way, adaptive and dynamic prioritization across logical channels can be achieved at the terminal device.

Logical channel prioritization

There is disclosed an apparatus comprising means for performing: receiving first radio capability information from a user equipment, the first radio capability information in a format of a first radio access technology; generating second radio capability information of the user equipment based on the first radio capability information, wherein the second radio capability information is generated in a format of a second radio access technology; and sending the first radio capability information and the second radio capability information to a core network node.

Signalling optimisation

Embodiments of the disclosure provide a method, device and computer readable medium for contention resolution in RACH. According to embodiments of the present disclosure, the terminal devices transmit random access requests in random access channels and the network device transmits the response to the random access requests on the downlink control channel addressed to the common identifier. According to embodiments of the present disclosure, there is one to multiple mapping for contention resolution radio network temporary identifier (CR-RNTI) and physical RACH (PRACH). In this way, the number of RNTIs is decreased and the overhead is reduced.

Contention resolution in random access procedure

A method, apparatus, and computer program product provide for generating and providing a signaling indicator to manage quality of service notifications in a network. In the context of a method, the method receives a signaling indicator from a user device. The signaling indicator includes data associated with one or more preferences of the user device. The method further receives a quality of service notification associated with the user device. The method also determines, based on the signaling indicator, whether to provide the quality of service notification to the user device.

Method, apparatus, and computer program product for alternative quality of service profile notification handling

In accordance with example embodiments as described herein there is at least an apparatus and method to perform transmitting packet data convergence protocol data unit duplicates over two or more carriers; receiving an indication that indicates packet data convergence protocol data unit has been correctly transmitted via one of two or more carriers; and upon receiving the indication, instructing to discard other packet data convergence protocol duplicates over carriers other than the one of two or more carriers with a successful delivery.

Duplication and RLC operation in new radio access technology

For a source stream of input data where FEC scheme(s) have been used to create a repair stream, transmitting by a network node packet(s) comprising data of the source stream or the repair stream packaged as at least part of PDU(s). An ARQ or HARQ process is applied to the PDU(s). The network node receives feedback information as part of the process corresponding to the PDU(s), including positive ACK/NACK response for the PDUs. The retransmissions of the negatively acknowledged PDU(s) are controlled when the FEC scheme is known not to be able to compensate for loss(e)s of packet(s) contained in the PDU(s) indicated as being negatively acknowledged. A UE receives packet(s), determines loss(es), and, in response to a determination the FEC scheme is known to be able to recover from the loss(es), sends at least one ACK for any lost packets that correspond to the one or more loss(es).

Forward error correction and RAN retransmission

Systems, methods, apparatuses, and computer program products for random access procedures are provided. One method may include provide at least one random access channel occasion (RO) to at least one lower layer. The method may optionally include receiving at least one indication of the at physical layer least one RO from the at least one lower layer. The method may further include initiating at least one timer configured to monitor at least one control channel based on the at least one indication.

Indication of random access response transmission

Embodiments of the present disclosure relate to a device, a method, an apparatus and a computer readable storage medium for bandwidth part (BWP) switching. In example embodiments, a method is provided. The method comprises determining, at a terminal device, whether continuous Listen-Before-Talk (LBT) failures occur on a first bandwidth part (BWP), the terminal device operating on the first BWP. The method further comprises in response to the continuous LBT failures occurring on the first BWP, switching to a second BWP different from the first BWP. Instead of triggering a re-establishment procedure once continuous LBT failures are detected, switching to another BWP on different LBT sub-channels can be much more efficient than going through the whole re-establishment and reconfiguration procedures.

Bandwidth part switching due to LBT failure

Systems, methods, apparatuses, and computer program products for the configuration of user device(s) for reception of point-to-multipoint transmission are provided. One method may include receiving, at a user equipment, a configuration for point-to-multipoint reception of a group-common transport channel. The configuration may include a group-common signaling configuration for a group of user equipment. The method may also include receiving, at the user equipment, a point-to-multipoint reconfiguration message using the group-common signaling configuration on the group-common transport channel from a device (e.g., a network node). The point-to-multipoint reconfiguration message may include an updated point-to-multipoint configuration. The method may then include receiving point-to-multipoint data, from the device on the group-common transport channel, based on the updated point-to-multipoint configuration.

Methods and apparatuses for configuration of user device(s) for reception of point-to-multipoint transmission

Systems, methods, apparatuses, and computer program products for user equipment are provided. A method may include determining to transmit, upon data arrival on a logical channel, the data on a configured grant for the logical channel. The method may also include transmitting, based on the determination, the data on the configured grant to activate a cell. In an example embodiment, the transmission on the configured grant may be performed regardless of a current activation status of the cell for which the configured grant is configured, or a suspend status of the configured grant.
