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.

Embodiments of the present application provide communication methods and systems. One method comprises receiving, from a first access network device, signaling destined for a terminal device, wherein the terminal device is in a radio resource control (RRC) inactive mode. A first paging message is sent to a second access network device for paging the terminal device and first indication information is received indicating that the terminal device is connected to a second access network device. After receiving the signaling destined for the terminal device, the first access network device can learn the terminal device has connected to the second access network device, and therefore performs proper subsequent processing.

Embodiments of the present application provide a method, a user equipment (UE), a base station, and a readable storage medium for transmitting a wake-up signal (WUS). The method is performed by the UE, and includes: receiving configuration information of a UE group WUS; determining the WUS corresponding to the UE group to which the UE belongs according to the configuration information of the UE group WUS; and monitoring the WUS corresponding to the UE group to which the UE belongs. The solutions of the embodiments of the present application may further reduce power consumption of the UE compared with the prior art.

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.
