A first base station (BS) receives at least one user equipment (UE) capability of the communication device, receives an access restriction configuration for the communication device. The first BS configures the communication device to measure a second radio access technology (RAT), when the at least one UE capability indicates that the communication device supports a dual connectivity (DC) of a first RAT and the second RAT and the access restriction configuration indicates that the communication device is allowed to use the second RAT; and not configures the communication device to measure the second RAT, when the at least one UE capability indicates that the communication device does not support the DC, or when the access restriction configuration indicates that the communication device is not allowed to use the second RAT.

Embodiments of this application disclose an information processing method, a base station, and a terminal. The method includes: receiving, by a master base station, a new radio packet data convergence protocol (NR PDCP) configuration and identification information of a data radio bearer (DRB) corresponding to the NR PDCP configuration from a secondary base station; and sending, by the master base station, the NR PDCP configuration and the identification information of the DRB to a terminal, where the master base station and the secondary base station are base stations of different radio access technologies (RATs).

Aspects of the present disclosure provide techniques for tunneling control information associated with random access procedure (RACH) from a fifth generation (5G) new radio (NR) base station (e.g., secondary base station (SgNB)) to the user equipment (UE) via long term evolution (LTE) master base station (e.g., MeNB) in order to extend the coverage of the SgNB. The tunneled PDCCH control information may include one or more of frequency domain resource assignment, time domain resource assignment (e.g., physical downlink shared channel (PDSCH) scheduled slot index, start symbol index and duration in the slow), and/or modulation coding scheme (MCS).

A method may include determining that a user equipment (UE) device is a dual connectivity device capable of communicating via a Fifth Generation (5G) network and a non-5G network. The method may also include receiving, a radio resource control (RRC) connection request, establishing an RRC connection with the UE device and determining whether the first wireless station is a dual connectivity wireless station. The method may further include initiating, in response to determining that the first wireless station is not a dual connectivity wireless station, a handover of a wireless connection to the UE device from the first wireless station to a second wireless station that is a dual connectivity wireless station, or identifying, in response to determining that the first wireless station is a dual connectivity wireless station, a 5G wireless station in the 5G network to act as a serving cell for the UE device.

Power retention for 5G non-standalone devices can be accomplished via a process that comprises specific message data being sent to a mobile device. For example, although a mobile device can enable its new radio in response to communicating with a network cell that does not comprise a new radio functionality, a message can be sent to the mobile device to prevent the mobile device from enabling its new radio. Therefore, the mobile device can retain battery power simultaneously.

Policy based dual connectivity traffic steering is described herein. A master Long-Term Evolution (LTE) base station may operate in conjunction with a secondary New Radio (NR) base station to provide dual connectivity to user equipment (UE) operating in an environment. The LTE base station can steer traffic between the LTE base station and the NR base station based at least in part on policy information received at the LTE base station. The policy information can indicate, for a particular UE and for a particular Quality of Service (QoS) Class Identifier (QCI), whether the LTE base station can transfer a communication to the NR base station. Thus, traffic steering determinations can be based on the policy information, quality identifiers, device capability, signal strength(s), load level(s), and the like, thereby providing a flexible framework for steering wireless traffic in a dual connectivity environment.

Disclosed herein is a method for establishing a connection between a terminal and a network entity in a wireless communication system including a Non-3GPP RAT. The method performed by a network entity comprises receiving, from the terminal, a first message including cell identification information indicating a last cell accessed by the terminal; running a first timer related to a paging when the network entity receives the first message; and transmitting a paging message to a cell corresponding to the cell identification information when the paging to the terminal is required before the running first timer expires.

A terminal apparatus configured to receive a measurement configuration from one or more base station apparatuses transmits a first measurement result and a second measurement result, and the first measurement result includes, as measurement results of a serving cell, the measurement results of the serving cell of a first cell group and the serving cell of a second cell group, and the second measurement result includes, as a measurement result of a serving cell, the measurement result of the serving cell of the second cell group.

A communication device for handling a bearer type change comprises at least one storage device for storing instructions and at least one processing circuit coupled to the at least one storage device. The at least one processing circuit is configured to execute the instructions stored in the at least one storage device. The instructions comprise receiving a first RRC message from a first BS; transmitting a first RRC response message to the first BS; establishing a PDCP entity; transmitting a first plurality of PDCP SDUs to the first BS; receiving a second RRC message from the first BS, wherein the second message configures the MCG bearer type to a SCG bearer type or a split bearer type; transmitting a second RRC response message to the first BS; reconfiguring the PDCP entity; and transmitting a second plurality of PDCP SDUs to a second BS when connecting to the first BS.

The present disclosure relates to a communication technique of fusing a 5G communication system for supporting higher data transmission rate beyond a 4G system with an IoT technology and a system thereof. The present disclosure may be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety related service, or the like) based on the 5G communication technology and the IoT related technology. More specifically, a method of the present disclosure for providing multi-connection of a terminal using different radio access technologies in a wireless communication system comprises the steps of: transmitting/receiving data through a first bearer corresponding to a first communication; transmitting/receiving data through a second bearer corresponding to a second communication; receiving, from a base station, a radio resource control (RRC) message which directs reestablishment of the first bearer as the second bearer or reestablishment of the second bearer as the first bearer; and reestablishing the first bearer or the second bearer on the basis of the RRC message.
