This document describes techniques and apparatuses for a user-equipment-coordination set for disengaged mode. In aspects, a base station forms a disengaged-mode-user-equipment coordination set including multiple user equipment operating in a disengaged mode. The disengaged-mode-user-equipment coordination set uses joint transmission and reception to communicate with the base station. The base station communicates control-plane information to an individual user equipment or multiple user equipment in the disengaged-mode-user-equipment coordination set.

Embodiments of the present application provide a communication method, comprising: receiving, by a first access network device from a core network device, signaling destined for a terminal, wherein the terminal is in a radio resource control (RRC) inactive mode; sending a first paging message to a second access network device for paging the terminal, wherein the first access network device and the second access network device are in same paging area; and receiving, from the second access network device, first indication information indicating that the terminal has connected to the second access network device. In the embodiments of the present application, after receiving the signaling destined for the terminal from the core network device, the first access network device can learn the terminal has connected to the second access network device, and therefore performs proper subsequent processing.

This disclosure describes systems, methods, and devices related to efficient poll response frame in wireless communications. A device may cause to send a multiuser location trigger frame of subtype poll to one or more initiating station devices (ISTAs) in a multi-user trigger-based range measurement during a polling phase. The device may identify a first clear to send (CTS) frame received from a first ISTA of the one or more ISTAs during the polling phase. The device may identify a second CTS frame received from a second ISTA of the one or more ISTAs during the polling phase. The device may determine the identity of a first ISTA based on information comprised in the first CTS frame received from the first ISTA. The device may determine the identity of the second ISTA based on information comprised in the second CTS frame received from the second ISTA.

In a communication system, a plurality of base stations includes an MeNB being a first base station, and a plurality of SeNBs to be connected to the MeNB. At least one of control plane data about control of communication and user plane data about a user is transmitted to and received from a user equipment (UE) via the first base station being the MeNB. The control plane data and the user plane data are contained in information provided by a core network about communication with the UE. The communication system can simplify processing of at least one of control plane data and user plane data when a communication terminal device communicates with a plurality of base station devices.

The present disclosure proposes a method capable of, when a user simultaneously selects several PTT channels even in an apparatus not supporting a display, identifying the several PTT channels using alarm sounds for the PTT channels to transmit voices and distinguishing through which PTT channel a received voice is received, and a PTT terminal supporting the same. The present disclosure provides a push-to-talk (PTT) communication method, comprising: a step of connecting multiple PTT channels for communications between terminals; a step of storing history information representing received time of voice data through the multiple PTT channels; a step of selecting a PTT channel on the basis of the history information with respect to the multiple PTT channels, if an input of a PTT button is sensed; and a step of transmitting voice data to the selected PTT channel.
