Methods, media, and systems are provided for controlling cell site selection by a user device in a telecommunications network. A System Information Block (SIB) message (e.g., an SIB Type 1 message) is transmitted (e.g., by a cell site) for receipt by the user device for cell site selection. In some aspects, the SIB message is transmitted while the user device is camping on a serving cell of a base station other than the cell site. The SIB message comprises information that identifies a type of the cell site. The type of the cell site is a cell site other than a macro cell, such as a small cell for example. Upon selection of the cell site by the user device based on the SIB message and the type of the cell site, the user device is provided access to a telecommunications service.

Cell selection priority

Systems and methods are provided for managing the power of a secondary node in an E-Utran/New Radio Dual Connectivity (ENDC) configured wireless communication network. In response to determining that one or more transmission blocking conditions have been met, a master node communicates an instruction to the secondary node via a data connection cable or an X2 logical interface to not transmit downlink signals, reducing overall power network power consumption and inter-nodal inference when ENDC resources are not required.

Power management of secondary node based on network conditions

A method and system for a base station (BS) configured for sharing among a plurality of public land mobile networks (PLMNs), and for providing open radio access and/or closed subscriber group (CSG) radio access for user equipment devices (UEs) served. The BS may make a determination of which PLMNs have enabled CSG and which have not, and may transmit a request to a core network of each PLMN to set up an interface connection with each. Based on the determination, the request may either include information for configuring CSG radio access, or information for configuring only open radio access. For each PLMN having CSG enabled, the interface connection may be established for CSG radio access for UEs associated with PLMNs having CSG enabled. For each PLMN not having CSG enabled, the interface connection may be established for only open radio access for UEs associated with PLMNs without CSG enabled.

Closed subscriber group setup of shared base stations based on public land mobile network configuration

Systems and methods for closed subscriber group identity (CSG ID) allocation for radio access network (RAN) sharing between different wireless telecommunication network providers can include a second CSG administration server receiving a unique first list of CSG IDs from a first CSG administration server, comparing the CSG IDs of the unique first list with a unique second list of CSG IDs associated with the second CSG administration server, and automatically adding to the unique second list ones of the CSG IDs from the unique first list that are absent from the unique second list. If a first one of the CSG IDs from the unique first list is already assigned in the unique second list, a new E-UTRAN Cell Global Identifier (ECGI) is added for use with the first one of the CSG IDs and sent therewith to the first CSG administration server to be added to the unique first list.

Systems and methods are provided for managing the power of a secondary node in an E-Utran/New Radio Dual Connectivity (ENDC)&#x2014;configured wireless communication network. In response to determining that one or more transmission blocking conditions have been met, a master node communicates an instruction to the secondary node via a data connection cable or an X2 logical interface to not transmit downlink signals, reducing overall power network power consumption and inter-nodal inference when ENDC resources are not required.

System and methods are provided for performing intra-cell beam switching based on customizable parameters for event detection. In embodiments, base station is configured with customized physical layer parameters, which the base station broadcasts. The base station uses reports of physical layer parameters of a beam, received from a user device, for example, to determine whether events have occurred that indicate beam switching should be performed. Based on the determinations, the base station may perform beam switching of the user device, in various embodiments.

A serving access node is determined as being capable of transmitting a mMIMO signal, responsive to which handover parameters are adjusted for wireless devices attached to the serving access node and receiving the mMIMO signal. Wireless devices attached to a sector deployed by a first access node and not the mMIMO signal are configured to utilize different handover parameters such that the non mMIMO wireless devices request handovers using standard signal level thresholds.

Adjusting handover parameters for massive MIMO wireless devices

Selecting a first BWP for a first carrier deployed by an access node based on requirements of wireless devices attached to the first carrier, selecting a second BWP for a second carrier deployed by the access node based on requirements of wireless devices attached to the second carrier, monitoring a MU-MIMO performance for each carrier, and performing handovers of wireless devices between the first and second carriers based on the MU-MIMO performance.

Performing MU-MIMO in wireless networks utilizing different bandwidth parts

Performing MU-MIMO based on bandwidth parts includes identifying a plurality of wireless devices attached to an access node, wherein each wireless device utilizes a different BWP, and wherein wireless devices using larger BWPs are located closer to the access node than wireless devices using smaller BWPs, and forming a MU-MIMO group comprising the plurality of wireless devices, while maintaining a uniform power spectral density by virtue of the differently-sized BWPs.

Performing MU-MIMO based on bandwidth parts

Beamforming in massive MIMO networks includes monitoring a signal condition such as pathloss of wireless devices and, based thereon, selecting a type of reference signal for the wireless devices, the type selected from among a non-precoded reference signal, a beamformed reference signal, or a standard reference signal. Further, an MCS of the wireless devices is monitored and, based thereon, the type of reference signal is adjusted.

Beamforming in massive MIMO networks

In an wireless communication system, base stations will be set to prioritize serving one type of user equipment device (UE) over another type of UE, and each base station's respective prioritization will be conveyed to UEs to facilitate base station selection. That way, when a UE faces a choice of whether to connect with one base station or another, the UE could determine which base station gives higher priority to the UE's type and could connect with that base station, even if the UE detects stronger coverage of the other base station. And if the UE finds itself in coverage of a base station that gives lower priority to the UE's type than to another UE type, the UE could still connect with that base station unless the UE finds another base station that gives higher priority to the UE's type.
