The method comprises obtaining an impact factor associated with RA of a terminal device to a network device, the impact factor indicating at least one of the following: a synchronization status between the terminal device and the network device, a status of a channel between the terminal device and the network device for performing RA, a capability of the terminal device for supporting early data transmission (EDT), a predefined access category of the terminal device, or a RA mode-related indication received from the network device; selecting a RA mode at least in part based on obtained impact factor; and performing RA to the network device with the selected RA mode. In this way, the terminal device may select different RA mode according to different scenario.

Disclosed is a method comprising detecting a beam failure on at least one transmission reception point of a plurality of transmission reception points. One or more beam failure indication data is included into a first medium access control (MAC) control element (CE), wherein the one or more beam failure indication data indicates the beam failure detected on the at least one transmission reception point. The one or more beam failure indication data comprises at least a first bit that comprises a first value and a second value, wherein the first value of the first bit indicates a first transmission reception point at least on which the beam failure is detected. The first MAC CE comprising the one or more beam failure indication data is transmitted to an access point.

Certain embodiments may provide enhancements related to physical layer design for multiple input multiple output and/or enhancements for a beam indication framework for scenarios with multiple transmission reception points and user equipment equipped with multiple antenna panels. A network node may transmit, and a user equipment may obtain, information indicating that one or more activated transmission configuration indictor states are associated with a set of beam groups.

A method, apparatus, and a computer-readable storage medium are provided for enhanced early measurement reporting procedures at a user equipment. In an example implementation, the method may include a user equipment determining that the user equipment is configured for enhanced early measurement reporting, determining whether to initiate early measurement reporting measurements based on an indication when the user equipment is configured for enhanced early measurement reporting, and initiating the early measurement reporting measurements in response to determining to initiate the early measurement reporting measurements. In an additional example implementation, the method may include a network node transmitting enhanced early measurement reporting configuration to a user equipment and receiving early measurement reporting measurements from the user equipment. The early measurement reporting measurements performed at the user equipment based at least on the enhanced early measurement reporting configuration.

Enhanced early measurement reporting

There are provided measures for enabling/realizing higher-layer beam management, e.g., beam failure detection or beam candidate detection in a higher layer such as a MAC entity. Such measures exemplarily comprise that a beam management timer is started when a (first) beam management instance indication from a lower layer is obtained, beam management is executed, wherein a beam management instance counter is incremented whenever a beam management instance indication from the lower layer is obtained and a beam management event is detected when the beam management instance counter reaches a beam management instance threshold before expiry of the beam management timer, and the beam management instance counter is reset upon expiry of the beam management timer.

Higher-layer beam management

The disclosure relates a method comprising: determining that buffered data is available for transmission and cannot be transmitted over allocated resources; and causing information indicating that buffered data is available for transmission and cannot be transmitted over allocated resources to be transmitted over the allocated resources.

Method, apparatus, computer program product and computer program

Example embodiments of the present disclosure relate to partial integrity protection in telecommunication systems. According to embodiments of the present disclosure, there is provided a solution for implementing partial integrity protection. The terminal device receives configuration of the partial integrity protection and applies the integrity protection on a portion of data packets which are communicated between communication devices. In this way, the communication devices can always provide integrity protection for services, regardless of their bit rate. Thus, security of communication can be improved. It also allows to provide integrity protection with limited impacts to power consumption and overheating.

Partial integrity protection in telecommunication systems

Embodiments of the present disclosure relate to for conditionally skipping monitoring of downlink control channel in random access. A first apparatus receives, from a second apparatus, a command indicating the first apparatus to skip monitoring a downlink control channel between the second apparatus and the first apparatus for a time period. The first apparatus initiates an RA procedure towards the second apparatus. The time period at least partially overlaps with a time window associated with the RA procedure and an end of the time period is after an end of the time window. The first apparatus determines whether the RA procedure is successfully completed or contention resolution for the RA procedure is successful. Based on the determination, the first apparatus ignores or performs the command after the end of the time window.

Conditional skipping monitoring of downlink control channel

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

According to an example aspect of the present invention, there is provided a method which includes detecting a failure. After detecting the failure, determining an association in response to identifying a new candidate beam for beam failure recovery, wherein the association is between a control resource set and at least one of a particular index and a beam failure recovery request. The method may also include transmitting a failure recovery request based on the association.

Failure recovery in cellular communication networks

Example embodiments of the present disclosure relate to a device, method, apparatus and computer readable storage medium of scheduling request (SR) and random access (RA) triggering for small data transmission (SDT). In example embodiments, a terminal device receives, from a network device, a configuration of one or more configured grant (CG) resources for a SDT procedure and a list of one or more data radio bearers (DRBs) associated with respective logical channels (LCHs) allowed for SDT over at least one of the one or more CG resources. After the terminal device initiates the SDT procedure in an inactive mode, if the terminal determines that a buffer status report (BSR) is triggered, the terminal device determines whether a configuration of a SR mask is to be applied for a LCH configured for SDT.
