Disclosed are a transmission device and a transmission method with which it is possible to prevent delays in data transmission and to minimize the increase in the number of bits necessary for the notification of a CC to be used, in cases where a CC to be used is added during communication employing carrier aggregation. When a component carrier is to be added to a component carrier set, a setting section provided in a base station: modifies a CIF table that defines the correspondence between code points, which are used as labels for the respective component carriers contained in the component carrier set, and the identification information of the respective component carriers; and assigns a vacant code point to the component carrier to be added, while keeping the correspondence between the code points and the component carrier identification information defined in the CIF table before modification.

Embodiments of the disclosure provide a method and device for performing communication. The method comprises: determining a target transmission pattern from a set of candidate transmission patterns, wherein each of the candidate transmission patterns contains a DL transmission part and/or a UL transmission part, and the candidate transmission patterns differ from one another in terms of time durations of the respective DL transmission parts and/or the UL transmission parts; and performing communication between a network device and a terminal device by using the target transmission pattern.

Methods, systems, and devices for wireless communications are described in which a narrowband device may communicate in a wireless communications network according to frequency hopping techniques. Devices using narrowband communications and frequency hopping techniques may maintain separate radio link monitoring (RLM) processes, beam failure detection (BFD) processes, beam failure recovery (BFR) processes, or combinations thereof, for multiple bandwidth parts (BWPs) or hop regions of a full channel bandwidth. Such separate processes may provide for enhanced estimates of beam failures per BWP or hop region, which may be used to enhance communications reliability.

The bandwidth-limited second communication device is operating in a particular component channel, and allocation of a frequency portion to the bandwidth-limited second communication device is restricted to the particular component channel. The first communication device transmits a data unit that includes one or both of: respective data for the second communication devices in the respective frequency portions allocated to the respective second communication devices, and one or more trigger frames to prompt transmission of respective data by the second communication devices in the respective frequency portions allocated to the respective second communication devices.

A user equipment (UE) and a method for small data transmission (SDT) are provided. The method includes receiving a Radio Resource Control (RRC) release message from a Base Station (BS), the RRC release message indicating an SDT configuration including a Configured Grant (CG) configuration and a timer; initiating a transmission on an Uplink (UL) resource while the UE is in an RRC_INACTIVE state, the UL resource being either configured by the CG configuration or scheduled by a UL grant from the BS; starting or restarting the timer after initiating the transmission; and monitoring a Physical Downlink Control Channel (PDCCH) addressed to a specific Radio Network Temporary Identifier (RNTI) on a specific search space while the timer is running.

Methods, systems, and devices for wireless communications are described. A wireless device, such as a base station or a user equipment, may identify an energy detection threshold for a sensing beam associated with a channel access procedure, such as a listen-before-talk (LBT) procedure. The wireless device may also identify a set of transmit power parameters for one or more transmit beams. The wireless device may determine a degree of overlap between a coverage area of one or more transmit beams and a coverage area of the sensing beam. The wireless device may adjust the set of transmit power parameters, the energy detection threshold, or a combination thereof based on the degree of overlap. The wireless device may perform the channel access procedure based on the determining, the adjusting, or both.

A road-side network node for operating in a cell-supported radio communications network is provided. The road-side network node comprises a processor, a memory, a radio module, and an antenna. The road-side network node is configured to: determine or receive a gap information indicating a transmission gap period on a sidelink radio channel; and transmit an energy signature via the sidelink radio channel within the transmission gap period.

A method is provided for enabling a User Equipment (102) to access services provided by a Radio Access Network by configuring the User Equipment (UE) with configuration information which comprises rules for selecting one or more of a plurality of access procedures to be used by the UE for accessing services provided by the Radio Access Network which may be a New Radio/5G network (101). Access procedures may include a grant-based procedure; a grant-free procedure and a fallback procedure to be used in cases of failure of an initial access attempt. The rules may be based on the type of service required by the UE such as; transmission and/or reception of data, transmission and/or reception of a voice call, a request for System Information.

A method includes determining, by a terminal device, a relation of size between an amount of data to be sent of a first split bearer of the terminal device and a preset threshold of the first split bearer, wherein the amount of the data to be sent includes a total amount of data volume in a PDCP layer of the first split bearer and an amount of data in a first RLC layer that is configured by a network side on the first split bearer and that is used to transmit data by default. The method also includes determining according to the relation of size in a plurality of cell groups corresponding to the first split bearer, a target cell group used to process the data to be sent according to the relation of size. The method facilitates load balance between cell groups and data transmission flexibility.
