Various examples and schemes pertaining to narrowband reference signal (NRS) transmission on non-anchor carriers in narrowband IoT (NB-IoT) are described. A wireless network indicates a subset of one or more paging groups of user equipment (UEs) among a plurality of UEs in an NB-IoT cell. The wireless network then transmits one or more narrowband reference signals (NRSs) in one or more paging frames or one or more paging occasions associated with the subset of one or more paging groups.

Various examples and schemes pertaining to user equipment (UE) group wake-up signal (WUS) in narrowband IoT (NB-IoT) are described. A wireless network indicates to a plurality of user equipment (UEs) a paging configuration of a UE-group wake-up signal (WUS) for one or more groups of UEs among the plurality of UEs in an NB-IoT cell. The paging configuration may be related to a discontinuous reception (DRX) cycle and a value related to UE identification of each UE in the one or more groups of UEs. The wireless network also transmits the UE-group WUS to the one or more groups of UEs.

A mobile terminal device may include a radio processing circuit and a baseband processing circuit adapted to interact with the radio processing circuit. The baseband processing circuit may be configured to identify one or more multicast control data notification messages available for reception during a first multicast control data window, determine whether any of the one or more multicast control data notification messages are not received during the first multicast control data window, and trigger receiving of multicast control data of a second multicast control data window when a predefined quantity of the one or more multicast control data notification messages are not received during the first multicast control data window.

A terminal receives configuration information from a first access network device. The configuration information includes a paging area information that indicates a paging area for the terminal in a first mode. In the first mode, the terminal sends a first message to a second access network device when the terminal is in a cell that does not belong to the paging area. The first message includes a paging area update indication. The terminal then receives a connection establishment indication from the second access network device, and establishes a connection between the terminal and the second access network device. The terminal sends a second message to a core network device using the established connection between the terminal and the second access network device, the core network device releases a connection between the first access network device and the core network device established for the terminal in response to the second message.

Embodiments of the present invention provide a paging message sending method, a paging message receiving method, and a device. A base station sends, to UE, configuration information of a first paging resource reserved by a core network for the UE. When the base station performs paging area paging on the UE, the base station sends, on the first paging resource, a first paging message to the UE. In the embodiments, all multiple cells included in a paging area use the first paging resource to perform paging area paging, and all the multiple cells use same paging scrambling code to scramble the first paging message when sending the first paging message.

Automated control of simulcast ratios based on network traffic data provides efficient network capacity management. In one aspect, a remote switching matrix can be utilized at a venue to couple remote transceiver units (RTUs) with different antenna ports, for example, of one or more multi-beam antennas deployed at the venue. A simulcast ratio that can be utilized to support traffic demand at the venue can be determined and implemented by creating dynamic connections between the RTUs and the antenna ports. In one aspect, the simulcast ratio can be modified based on changes in network traffic at the venue that are monitored via self-organizing network devices. In addition, one or more antenna beams of the multi-beam antennas are remotely steered or rotated based on a location of the traffic.

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.
