An electronic messaging device includes a receiver configured to receive a message at one of a first operational frequency and second operational frequency. The messaging device can added to a message distribution group comprising a plurality of existing messaging devices. A test communication can be sent through a coupling to test an operation of the messaging device and confirming the addition of the messaging device to the message distribution group without communicating with the existing messaging devices.

A method for allowing a user equipment (UE) and a base station (BS) to transmit and receive uplink (UL) signals in a wireless communication system is disclosed.

A radio terminal according to one embodiment comprises: a controller configured to detect a radio problem in communication with a base station in an RRC connected state and attempt a recovery from the radio problem; and a transmitter configured to transmit, to the base station, a polling signal for confirming whether or not the base station considers an RRC state of the radio terminal as the RRC connected state in response to the successful recovery. The controller maintains the RRC connected state in response to reception, from the base station, of a response signal to the polling signal.

A terminal apparatus includes a receiver configured to receive a radio resource control (RRC) reconfiguration message from a base station apparatus, and a controller configured to configure a parameter based on the parameter included in the RRC reconfiguration message. The parameter includes at least identity information of a target cell and a configuration of a subcarrier spacing, and the configuration of the subcarrier spacing is configured for each of the target cells.

Method and device for reporting and acquiring a UE capability are provided, wherein the reporting method includes that: a UE reports to a base station indication information indicating that the UE has a dual connectivity support capability. Employment of the above technical solution provided in the present disclosure and employment of the technical means in which a UE reports to a base station indication information for indicating that the UE has a dual connectivity support capability solve the technical problem in the related art that the base station is incapable of learning that the UE has the dual connectivity support capability, thus enabling the base station to configure a suitable dual connectivity for the UE according to the dual connectivity capability of the UE, and enhancing user experience.

This disclosure relates to techniques for supporting message mapping via time and/or frequency indexing. For example, these techniques may be applied to device-to-device wireless communication. For example, device to device discovery may use message mapping via frequency indexing. A portion of the payload of a message, such as a discovery message, may be offloaded to a frequency and/or time index. A receiving device may determine the offloaded portion of the payload based on the frequency and/or time (e.g., subcarrier and/or slot) used to transmit the message.

A terminal and an operating method thereof are provided in a wireless communication system. The method includes receiving, from a base station, a radio resource control (RRC) message including configuration information related to a measurement of the terminal; performing the measurement based on the RRC message; identifying whether a measurement report entry corresponding to a measurement identifier related to the measurement is included in a list regarding a measurement report of the terminal; and performing a measurement report based on a result of the identifying.

A data transmission method, a device, and a system are disclosed and relate to the communications field, to resolve a problem that modulation and coding cannot be performed on data because no corresponding transport block size TBS exists when a quantity of physical resource blocks PRBs of a wireless communications system is greater than 110. A specific solution is: obtaining, by a first device, grouping information, where the grouping information is used to indicate information of grouping N PRBs into M PRB groups; performing modulation and coding by using a TBS that corresponds to each of the M PRB groups, to generate modulation symbols; and transmitting data to a second device by using a physical resource that corresponds to the N PRBs. The foregoing solution is used for data transmission in a wireless network.

An information processing method and apparatus in the field of mobile communications technologies is provided. In the method, a first terminal obtains, during a call with a second terminal by using voice information sent by the second terminal, to-be-obtained information and object information of an object to which the to-be-obtained information belongs. The first terminal determines at least one category to which the to-be-obtained information belongs and determines a group that is in any category of the at least one category and corresponding to the object to which the to-be-obtained information belongs. The first terminal searches information in the corresponding group in any category for target information associated with the object information and processes the target information with no manual searching being performed.

Disclosed as a method of controlling access to a network in a wireless communication system and an apparatus therefor. Specifically, a method of performing access to a network by a user equipment (UE) in a wireless communication system may include receiving first information on whether a specific access identity is valid in a specific public land mobile network (PLMN) from the network, when the UE selects a PLMN and attempts access, determining whether the specific access identity is valid in the PLMN selected by the UE based on the first information, selecting an access identity based on the determination, and performing an access control procedure based on the selected access identity.
