CONTROL NETWORK NODE, NETWORK NODE AND METHODS PERFORMED THEREIN
A method performed by a control network node for handling a radio resource in a frequency band. The control network node receives an indication related to a performance of a first radio network node or a performance of user equipment served by the first radio network node. The control network node further triggers a performance adjustment related to at least one radio network node of a number of radio network nodes or to the first the radio network node based on the indication.
MAC CE FOR CONFIGURING PATHLOSS REFERENCE SIGNAL FOR PUSCH
Methods and apparatuses for configuring PUSCH pathloss reference signal for SRI PUSCH power control are disclosed. A method comprises configuring PUSCH pathloss reference signal for one or more SRI PUSCH power controls by using a MAC CE, and transmitting a PDSCH carrying the MAC CE.
POWER ALLOCATION PRIORITIZATION AT FULL DUPLEX USER EQUIPMENTS
Aspects presented herein may enable FD devices to apply power backoff and/or power allocation prioritization rules that are specific to FD transmissions. In one aspect, a UE determines an FD specific power backoff associated with each of at least one transmission of a plurality of transmissions in a slot that is configured as an FD slot, each FD specific power backoff is based on whether a corresponding transmission would cause self-interference with a DL reception in the FD slot, and the plurality of transmissions are overlapping in time. The UE determines a transmission power for each of the at least one transmission in the FD slot based on the determined FD specific power backoff for each of the at least one transmission. The UE transmits one or more of the at least one transmission based on the determined transmission power for the corresponding transmission.

POWER CONTROL FOR ARTIFICIAL NOISE TRANSMISSION FOR PHYSICAL LAYER SECURITY
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration associated with artificial noise assisted physical layer security for at least one of an uplink channel or a sidelink channel. The UE may receive an indication of a power allocation parameter associated with a power allocation between a data signal and an artificial noise signal. The UE may transmit, via the uplink channel or the sidelink channel, at least one of the data signal or the artificial noise signal with the power allocation between the data signal and the artificial noise signal based at least in part on the power allocation parameter. Numerous other aspects are described.
Open loop feedback power control for multicast transmissions
Methods, systems, and devices for wireless communications are described. In one example, a user equipment (UE) may be configured to receive a control message scheduling a multicast transmission, and the UE may identify an open loop power control parameter for transmitting acknowledgment feedback responsive to the multicast transmission. The identification of the open loop power control parameter may be based on the transmission being multicast to a plurality of UEs, and in some cases a UE may identify an open loop power control parameter that is different than an open loop power control parameter associated with feedback responsive to unicast transmissions. In various examples, open loop power control parameters may correspond to respective feedback resources (e.g., according to a configuration for a set of open loop power control parameters), or to respective physical resource indicators (e.g., as signaled in downlink control information).
Enhancements to channel state information reporting
Certain aspects of the present disclosure provide techniques for enhancements to channel state information (CSI) reporting. A method that may be performed by a user equipment (UE) includes obtaining, from a network entity, a CSI reporting configuration for reporting CSI for a channel. The method further includes generating a model of an interference pattern for the channel, and predicting one or more candidate interference levels for one or more upcoming slots using the model. The method further includes reporting information regarding the candidate interference levels to the network entity.
Uplink information transmission method and apparatus
This application provides an uplink information transmission method and apparatus. The method includes: determining a value of a power control parameter in a value set of the power control parameter, where any value set of the power control parameter includes at least two values; sending indication information to a terminal device, where the indication information is used to indicate the value of the power control parameter; and receiving uplink information, where the uplink information is from the terminal device at a transmit power adjusted based on the value of the power control parameter.
Methods for performing power control in new radio (NR) systems
The disclosed method and an apparatus are directed to determine an uplink transmission power in New Radio (NR) systems by a wireless transmit/receive unit (WTRU) for transmitting at least one physical uplink shared channel (PUSCH), using multiple beams toward multiple Tx/Rx points (TRPs). The method includes determining common parameters that are common to the multiple beams. The method also includes determining beam-specific parameters like a configurable fractional power compensation factor for each beam, and a configurable maximum transmit power level for each beam, which are determined dynamically or semi-statically based on deployment, WTRU mobility, or interference level. The method further includes transmitting at least one codeword using at least one of the multiple beams, each of the multiple beams having a transmission power calculated based on the common parameters and the beam-specific parameters.
Sidelink power control
Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing and reporting reference signal received power (RSRP) measurements. In particular, the techniques described herein may allow a user equipment (UE) to efficiently identify reference signals on which to perform RSRP measurements (e.g., based on signaling from a base station), identify when to report RSRP measurements (e.g., aperiodically, periodically, or semi-persistently), and identify a channel on which to report RSRP measurements (e.g., a sidelink channel or an uplink channel). In addition, the techniques described herein may also allow a UE to efficiently identify open loop parameters to use to determine an appropriate transmit power for transmitting to another UE over a sidelink.
