The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and apparatus of a wireless network are disclosed. The method includes transmitting a first request message to request allocation of a multimedia broadcast multicast service (MBMS) group identifier from a service capability server/application server (SCS/AS) to a service capability exposure function (SCEF), the first request message including an external group identifier and an SCS/AS identifier, and receiving a first response message including the MBMS group identifier from the SCEF to the SCS/AS.

A system that incorporates the subject disclosure may perform, for example, a method for receiving interference information, identifying a plurality of interferers, approximating a location of the plurality of interferers, and adjusting an antenna pattern of an antenna. The method can include determining traffic loads and adjusting the antenna pattern according to the traffic loads. Other embodiments are disclosed.

There is provided a wireless device including an acquisition unit (110) that acquires a distribution amount of an interference margin to a second wireless system that shares a part or a whole of a frequency allocated to a first wireless system, from a device that manages one or more of the second wireless systems, and a control unit (120) that determines, from the interference margin, a distribution amount of the interference margin to a terminal that performs wireless communication with the wireless device in the second wireless system.

An indication information sending method includes that a base station generates first indication information, and send the first indication information to a terminal device; and where the first indication information is used to indicate a power control manner of a first channel, the power control manner of the first channel is one power control manner in a power control manner set, and the power control manner set comprises a transmit power of a signal on the first channel is determined by a terminal device based on a first parameter; or a transmit power of a signal on the first channel is determined by a terminal device according to a rule predefined on the terminal device.

Systems and methods are disclosed for improving communication efficiency in environments featuring both 802.11ax devices and legacy devices. Although 802.11ax introduces the ability for multiple devices to transmit simultaneously over a wireless channel, this feature is not used to its full potential because legacy devices transmit using turn-based communication (waiting for the channel to free up before transmitting). To create the illusion that the channel is free, in one method, an 802.11ax access point lowers the power for 802.11ax transmissions in a portion of a wireless channel being utilized by the legacy device. In another method, the 802.11ax access point blanks the portion of the wireless channel altogether (i.e., does not schedule transmissions over the portion). As a result of these methods, signal interference is reduced, and legacy devices do not halt transmissions to follow turn-based communication.

Aspects of the present disclosure provide techniques for addressing scenarios where the minimum transmit power supported by an Integrated Access and Backhaul (IAB) node is above a minimum value specified by a standard. In some cases, the IAB node may signal information regarding its power configuration so a network entity of the IAB may take it into account (e.g., when allocating or scheduling resources). The power configuration may include an indication of the minimum transmit power supported by the IAB node and/or an indication of a guard band that may help the IAB node control adjacent channel leakage.

According to some embodiments, a network node configured to communicate with a wireless device is provided. The network node (16) includes processing circuitry configured to: configure a first measurement resource for channel measurements, configure a second measurement resource for interference measurements, cause transmission of a first signal with a first predefined power level in a transmission occasion of the first measurement resource, and cause transmission of a second signal with a second predefined power level in a transmission occasion of the second measurement resource where at least one of the first predefined power level and the second predefined power level is configured to at least in part mitigate channel quality indication, CQI, saturation.

One example of a device includes a Bluetooth transceiver, a Wireless Local Area Network (WLAN) transceiver, and a controller. The WLAN transceiver is proximate the Bluetooth transceiver. The controller is communicatively coupled to the Bluetooth transceiver and the WLAN transceiver. The controller is configured to adjust a cell size of the WLAN transceiver or the Bluetooth transceiver to reduce interference between WLAN transceiver traffic and Bluetooth transceiver traffic.

In one of its example aspects the technology disclosed herein concerns an Integrated Access and Backhaul (IAB) node (24) that communicates over a radio interface. The IAB node comprises mobile-termination circuitry (50), distributed unit circuitry (52), and processor circuitry (54). The mobile-termination circuitry is configured to transmit over the radio interface with a parent node. The distributed unit circuitry is configured to transmit over the radio interface with a child node. The processor circuitry is configured to manage transmission power utilized by the IAB node by taking into consideration both transmission by the mobile-termination circuitry and transmission by the distributed unit circuitry. Other example aspects of the technology disclosed herein concern transmission power reporting by such IAB node, transmission power prioritization by such IAB node; transmission power governance for the distributed unit circuitry for such IAB node; and method of operating such IAB node(s).

In a first embodiment, a method is disclosed, comprising: determining when and where to create a 2G/Narrowband-Internet of Things (NB-IOT) carrier at a 2G base station; starting up the 2G/NB-IOT carrier; creating an interference-free zone for a co-located 4G or 5G carrier co-located with the 2G base station; turning off the 2G/NB-IOT carrier; and reverting the interference-free zone. The method may further comprise embedding one or more 2G/NB-IOT carriers in a guard band of 4G/5G. The method may further comprise transmitting a 2G/NB-IOT carrier from a co-located base station. The method may further comprise using Self-organizing Network (SON) information to determine when a 2G/NB-IOT carrier should be started or shut down. The method may further comprise shutting down a 2G/NB-IOT carrier after use. The method may further comprise creating interference free zones in required regions of the spectrum. The method may further comprise creating interference free zones using a Relative Narrowband Transmit Power (RNTP) Information Element of a X2AP protocol. The method may further comprise creating interference free zones across multiple neighboring eNBs.
