An aspect of the present disclosure is directed to a network node for performing communication in a wireless communication network. The network node is configured to receive a signal transmitted by a user device in the wireless communication network, measure a received power level at which the signal is received by the network node, determine, based on a predefined transmit power level of the network node, based on a predefined transmit power level of the user device and based on the received power level, a threshold power level for a clear channel assessment to be performed by the user device, and trigger transmitting an indication of the threshold power level to the user device. Further aspects of the disclosure pertain to a user device, methods and a computer program product.

Aspects of the subject disclosure may include, for example, obtaining channel cross correlation data relating to multiple user equipment (UEs) being served in a cell, wherein the channel cross correlation data comprises a correlation coefficient associated with a first UE of the multiple UEs and a second UE of the multiple UEs, identifying that the first UE is experiencing decreasing throughput, responsive to the identifying that the first UE is experiencing decreasing throughput, determining whether the correlation coefficient associated with the first UE and the second UE satisfies a correlation threshold, and, based on a first determination that the correlation coefficient does not satisfy the correlation threshold, adjusting a downlink (DL) transmit power allocation for transmissions directed to the first UE. Other embodiments are disclosed.

Wireless communications are described. A wireless device may determine a first transmission power for a first signal and a second transmission power for a second signal. The wireless device may reduce signal transmission power of one or more of the first signal or the second signal, based on a calculated power value exceeding an allowable transmission power. The wireless device may reduce the signal transmission power during an overlap period or a non-overlap period, based on a duration of an overlap of the first signal with the second signal.

For improved messaging reliability in 5G and 6G, mobile users and their base stations can adjust their transmission power according to the current location of the mobile user. Each entity can maintain a map of known attenuation values, including “dead zones”, and can adjust their transmission power and/or reception gain to compensate. Instead of constantly exchanging location-update messages, the users can indicate their speed and direction, and the base station (or other users) can extrapolate the location versus time to determine a future location, and thereby determine the attenuation factor at the new position. In addition, the base station can use a map to follow the mobile user device's progress, and can thereby update the attenuation factor in real-time. If the mobile user makes a change, it can inform the base station at that time, or during initial access. Result: improved reliability, lower energy consumption, improved traffic safety.

An access point (AP) communicates to one or more stations (STAs) information indicating a set of channels and/or resource units (RUs), corresponding to a wideband basis service set (BSS) for an authorized unlicensed radio local area network (RLAN) using 6 GHz spectrum, which are subject to a lower power spectral density (PSD) level than other portions of the BSS frequency range or are not to be used for transmission. In some, but not necessarily all, embodiments, the AP and the STAs do not encode data on the identified channels or RUs, but do encode data on other channels and/or other RUs, which are not subject to the lower PSD constraint.

Certain aspects of the present disclosure provide techniques for determination, selection, configuration, and/or indication of resource allocation patterns for scheduling services, such as reliable low-latency services (e.g., ultra-reliable low latency communications (URLLC)) and other services in a wireless network, such as new radio (NR) (e.g., a 5G network). A method of wireless communication by a user equipment (UE) is provided. The method generally includes determining a resource allocation pattern that defines resources, from a plurality of configured resource allocation patterns, wherein at least one of the plurality of configured resource allocation patterns comprises a plurality of resource elements with at least a first resource element associated with a first resource allocation restriction and at least a second resource element associated with a second resource allocation restriction and communicating based on the determined resource allocation pattern.

A method and apparatus are disclosed herein for controlling transmit power in a station (STA) of a wireless local area network (WLAN). A STA may transmit, to another STA, transmit power step size information that indicates a maximum transmission power for an operational bandwidth that the STA supports. The STA may receive, from another STA, a signal in one of the plurality of operational bandwidths that the STA supports. The received signal may include a transmission power based on the transmitted adjustment step size setting.

The invention relates to methods for informing an eNodeB on the transmit power status of a user equipment in a mobile communication system using component carrier (CC) aggregation. Furthermore, the invention is also related to the implementation of these methods by hardware and their implementation in software. The invention proposes procedures that allow the eNodeB to recognize the power usage status of a UE in a communication system using carrier aggregation. The UE indicates to the eNodeB, when the UE is close to using its total maximum UE transmit power or when it has exceeded same. This is achieved by the UE including indicator(s) and/or new MAC CEs to one or more protocol data units transmitted on respective component carriers within a single sub-frame that is providing the eNodeB with power status information. The MAC CEs may report a per-UE power headroom. Alternatively, the MAC CEs may report per-CC power headrooms and/or power reductions applied to the respective uplink CCs.

In M2M communication, data transmission is performed 4 msec after control information for dynamic scheduling is received from a base station apparatus, and the data transmission that needs immediacy has more overhead. In a case where a transmission apparatus performs data transmission to a reception apparatus, there are a first transmission mode in which a data signal based on a transmission parameter included in the received control information is transmitted, and a second transmission mode in which the control signal information is not received, and the data signal is transmitted without the reception apparatus being notified of a transmission timing of the data signal. In a case where transmission of an SR is possible and in a case where data communication is possible with the first transmission mode and the second transmission mode, the transmission apparatus configures different transmission powers in accordance with the transmission modes.

Methods and apparatuses are described for wireless communications. Cells may be grouped into a plurality of cell groups. A wireless device may transmit a plurality of preambles. The wireless device may also transmit a packet using a transmission power that is based on a power ramp-up of the preambles.
