Various aspects of the present disclosure generally relate to wireless communication. A wireless communication device may have an apparatus that aligns the non-linearity between transmit chains of the wireless communication device that are driven by the same digital port. The apparatus may adjust an amplification power out or an amplification saturated power to adjust a ratio between the amplification saturated power and the amplification power out for one or more transmit chains of the wireless communication device. The apparatus may adjust the ratios of transmit chains to align the ratios of the transmit chains for more consistent management of non-linear characteristics of the chain components. Numerous other aspects are described.

A method and an apparatus for transmitting indication signaling, a method and an apparatus for receiving indication signaling, a network side device and user equipment are provided. The method includes: transmitting indication signaling on a target physical resource or a target downlink control channel, wherein the indication signaling includes monitoring information for at least one UE, and the monitoring information includes at least one of: first indication information, used to indicate an activity state for at least one subsequent discontinuous reception (DRX) cycle; second indication information, used to indicate a DRX parameter configuration for the at least one subsequent DRX cycle; third indication information, used to indicate monitoring information of a downlink control channel to be monitored; fourth indication information, used to indicate a monitoring state in at least one subsequent paging occasion.

A method and apparatus for power control for wireless transmissions are disclosed. A wireless transmit/receive unit (WTRU) may reduce transmission power to channels for carrier aggregation such that a total transmit power of the WTRU is smaller than or equal to a maximum transmission power level in all symbols of a transmission. Further, transmission power may be allocated to the channels for carrier aggregation based on priority. Also, transmission power may be allocated to a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) with uplink control information over a PUSCH without uplink control information. Moreover, transmission power may be allocated to a PUCCH or a PUSCH over a sounding reference signal (SRS) transmission. Additionally, the WTRU may transmit data over one or more channels, of the channels for carrier aggregation, at the respective transmission power allocated to the one or more channels.

A mechanism for distributing traffic between a macro access node and a micro access node in a heterogeneous network is described. The method, performed by a network node controller, comprises obtaining information of current traffic load in the heterogeneous network. The method further comprises distributing the traffic between the macro access node and the micro access node by adjusting cell shaping beams of the macro access node as a function of the current traffic load.

A method and an apparatus for determining and configuring an uplink channel parameter. The method includes: receiving target indication information sent by a network-side device, where the target indication information includes at least one of the following: transmission configuration indicator state information and first indication information, and the transmission configuration indicator state information or the first indication information is used to indicate an uplink channel parameter for transmission of a physical uplink shared channel PUSCH; and determining the uplink channel parameter based on the target indication information.

A method and a network node (300) for enabling wireless communication with a wireless device (302), wherein no more than a pre-determined maximum total transmit power is available for downlink transmission by the network node (300). When detecting that the wireless device (302) requires an extended transmission range (300B) which is larger than a nominal transmission range (300A), a boosted transmit power is determined and used for transmitting a first set of channels and/or signals to be used by the wireless device (302) to achieve the extended transmission range (300B). An attenuated transmit power is also determined and used for transmitting a second set of channels and/or signals not included in the first set of channels and/or signals, which provides a slightly reduced transmission range (300C) for the second set. The boosted transmit power is thus higher than a nominal transmit power, and the attenuated transmit power is lower than the nominal transmit power, so that the total transmit power used for transmitting said first and second sets does not exceed the pre-determined maximum total transmit power.

Facilitating adaptive power spectral density with chromatic spectrum optimization in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can comprise evaluating, by a system comprising a processor, a capture rate of mobile devices within a radio access network. The capture rate is representative of a quantity of mobile devices using a millimeter wave spectrum of the radio access network. The method also can comprise facilitating, by the system, an adjustment to a power spectral density of the radio access network based on a determination that the capture rate fails to satisfy a target capture rate of mobile devices using the millimeter wave spectrum.

There is provided an apparatus, said apparatus comprising means for determining which of at least two lower layer radio units co-located at a first location, each lower layer radio unit associated with a higher layer radio unit, has a best path to the associated higher layer radio unit and causing the transmit power of the determined one of the at least two lower layer radio units received at a user equipment to be higher relative to the transmit power of any of the other of the at least two lower layer radio units received at the user equipment.

Disclosed are methods for adjusting cell coverage of a multimedia broadcast multicast service. An example method (700) may include transmitting (701) data of a multimedia broadcast multicast service on a point-to-multipoint channel, monitoring (702) an uplink channel for information on an abnormal reception of the data, and adjusting (703) coverage of the point-to-multipoint channel based on the monitoring. Related apparatuses and computer readable media are also disclosed.

A communications system is disclosed. The communications system includes a first access point and a second access point whose operating channels overlap. The first access point and the second access point each measure a signal strength of a response frame sent by a terminal device associated with the first access point, to obtain a first signal strength and a second signal strength. The first access point determines, based on the first signal strength and the second signal strength, a power, a power upper limit, or a power adjustment value to be used by the second access point when the second access point and the first access point perform concurrent transmission. The communications system can perform a step of measuring the signal strength in the concurrent transmission between the access points, and reduce dependence on the terminal device.
