The link information indicating the above is notified a communication terminal device by a base station device using the DL CC2. A DL CC1 and a UL CC constitute a cell1. The downlink communication from the base station device to the communication terminal device is performed using the cell1 and the cell2, and the uplink communication from the communication terminal device to the base station device is performed using the cell1.

Abstract: A system and method for providing anonymous communications from a user to a called party includes obtaining a dedicated phone number and creating a user account for the user and assigning the dedicated phone number to the user account. A provider account is created for a digital assistant using the dedicated phone number and the digital assistant is preprogrammed with the user account. The digital assistant is also preprogrammed with a skill for recognizing a specific utterance (e.g. “Call”). Connectivity is provided between the digital assistant and the Internet, for example, using a wireless access point. The digital assistant listens for the specific utterance and, upon recognizing the specific utterance followed by an identification of the called party, the digital assistant initiates a voice call through the Internet to the called party.

Abstract: Techniques for improving the power management of devices are described. In an example, a device transitions into a power save mode. While in the power save mode, the device performs a number of operations. The operations include transitioning into an awake state and determining that the device has no data to transmit to a network access device. The operations also include determining a sequence number associated with data transmission to the network access device. The operations further include generating a frame that includes a header field and a payload field. The header field includes the sequence number and power management data. The power management data indicates a transition of the device to the awake state. Additionally, the operations include transmitting the frame to the network access device.

Abstract: Access, mobility management and regulatory services are supported for satellite access to a Fifth Generation (5G) core network (5GCN). A location of a UE may be obtained by a UE or by a base station and used to determine a country in which the UE is located. The UE can then select a serving PLMN in the country of the UE which is accessible from a radio cell supported by a satellite. The UE can register with the serving PLMN and receive information from the serving PLMN concerning fixed cells and fixed tracking areas supported by the serving PLMN. If the UE attempt to register with a PLMN not in the country of the UE, a serving base station can reject the attempt and indicate the country to the UE.
