A wireless device may receive a configuration parameter indicating that a survival time state is configured for a first radio bearer. The wireless device may determine to enter a survival time state for the first radio bearer in response to receiving a retransmission grant for a transport block comprising data of a logical channel associated with the first radio bearer. In response to receiving control information, the wireless device may determine to exit from the survival time state for the first radio bearer and remain in the survival time state for a second radio bearer.

A first UE may receive, from a base station or a second UE, one or more first TCI states via RRC signaling. The first UE may receive, from the base station or the second UE, one or more MAC-CEs. Each of the one or more MAC-CEs may include at least one indication of one or more second TCI states. The one or more second TCI states may be a subset of the one or more first TCI states. The first UE may transmit to the second UE, or receive from the second UE, a sidelink message via a sidelink channel based on a third TCI state. The third TCI state may be from the one or more second TCI states.

A terminal according to one aspect of the present disclosure includes a transmitting section that transmits first information to notify occurrence of beam failure and second information related to at least one of a cell with the beam failure detected and a new candidate beam, and a control section that performs, when transmission of the second information is performed after the first information is triggered, at least one of cancellation of the triggered first information and stopping of a timer started based on transmission of the first information.

The disclosed technology is directed towards associating a distributed unit (a baseband function) with a radio unit, corresponding to a service area, when the radio unit transitions from an idle state to an active state with respect to serving user equipment. When an idle radio unit receives a message requesting connection from a formerly idle user equipment, or user equipment to be served due to a handover, the message triggers assignment of a distributed unit to the radio unit, whereby the radio unit becomes active to serve the user equipment. If insufficient distributed unit capacity exists, a new distributed unit is dynamically instantiated and assigned to the radio unit. When a radio unit transitions from active to idle, the radio unit is disassociated from the distributed unit. If a distributed unit is not associated with any radio unit, the distributed unit is deactivated to reduce resource consumption.

A communication apparatus communicates a wireless frame compliant with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 series standard with a partner apparatus, wherein a media access control (MAC) frame of the wireless frame includes information indicating a frequency channel as information related to communications via a plurality of links compliant with the IEEE 802.11 series standard to be established on a plurality of different frequency channels where an apparatus transmitted the wireless frame and a partner apparatus can perform wireless communication compliant with the IEEE 802.11 series standard.

The present disclosure provides a method and a device used for discontinuous reception. A first node monitors a first signal in a first time resource pool, a first bit block is used to generate the first signal, the first bit block comprises a MAC PDU, and the first bit block comprises a first identification component; and a second receiver, when the first signal is successfully received in the first time resource pool, monitors a first signaling in a first time-frequency resource block; when the first signal is not successfully received in the first time resource pool, drops monitoring a first signaling in a first time-frequency resource block. The application can avoid the introduction of sidelink MAC CE to maintain the compatibility with the existing standards as far as possible; in addition, the application can reduce the overhead of air interface.

In some examples, a headless device that is without an available user interface and that is to be provisioned for access to a network receives information relating to provisioning of the headless device from a network node. The headless device sends, to a mediator device with a user interface, at least a portion of the received information. The headless device receives, from the mediator device, information to proceed with the provisioning of the headless device.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting uplink data in a wireless communication system. According to an aspect of the present invention, the method comprising: receiving information including contention based channel configuration and traffic characteristic associated with the contention based channel configuration; configuring a contention based channel resource according to the contention based channel configuration; checking whether uplink (UL) data is suitable for the traffic characteristic associated with the contention based channel configuration; and transmitting the UL data using the contention based channel resource if the UL data is suitable for the traffic characteristic associated with the contention based channel configuration.
