Embodiment Construction

[0068] In some examples of wireless communication systems, a user equipment (UE) may be simultaneously connected (eg, via dual connectivity (DC) communication) with a first base station and a second base station, and may consume resources allocated by both base stations. The first base station and the second base station may be referred to as a master node (MN) and a secondary node (SN). The MN may be, for example, a base station responsible for managing handover signaling, paging and bearer setup / release procedures. The SN may be a base station that provides additional resources to the UE but may not perform management functions of the MN. The MN and SN may operate on different carrier frequencies and may communicate with UEs via the same or different radio access technologies (RATs), such as via Long Term Evolution (LTE) RATs or New Radio (NR) RATs. In some cases, the UE may first establish a connection with the MN, and then establish communication with the SN (eg, using ad...

Abstract

Methods, systems, and devices for wireless communications are described. A first base station may identify that the first base station is a secondary node for user equipment (UE) operating in a dual connectivity deployment, wherein the UE is in a radio resource control (RRC) inactive state. The first base station may receive, from the UE, a request to resume communications with the first base station and a second base station that is a master node in the dual connectivity deployment. The first base station may verify the UE using an access stratum context associated with the UE, and resume communications with the UE based at least in part on the request and the access stratum context. The first base station may resume communications as a secondary node or as a master node. In some cases, the UE may resume communications without entering an RRC idle state.

Description

[0001] Cross References to Related Applications [0002] This patent application claims International Patent Application No. PCT / CN2018 / 115014 by Liu et al., entitled "RESUMING COMMUNICATION WITH SECONDARY NODE IN DUAL CONNECTIVITY," filed November 12, 2018, which is assigned to the assignee herein person, the entire contents of which are incorporated herein by reference. technical field [0003] The following relates generally to wireless communications, and more specifically to resuming communications with secondary nodes in dual connectivity deployments. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication for multiple users by sharing available system resources (eg, time, frequency, and power). Examples of these multiple access systems include fourth generation (4G) sys...
