Wireless communications systems and methods related to listen-before-talk (LBT) are provided. A first wireless communication device performs an LBT in a channel to contend for a first transmission opportunity (TXOP). The first wireless communication device receives, from a second wireless communication device, a first reservation signal reserving a second TXOP in the channel in response to the LBT, the second TXOP being different from the first TXOP. The first wireless communication device adjusts a signal detection threshold based on transmit power information associated with at least one of the first wireless communication device, the second wireless communication device, first data traffic to be communicated in the first TXOP, or second data traffic to be communicated in the second TXOP. The first wireless communication device determines whether to yield channel access during the second TXOP based on a signal measurement of the first reservation signal and the adjusted signal detection threshold.

Methods and apparatus for changing cell range coverage are disclosed. A wireless transmit/receive unit (WTRU) may include circuitry configured to transmit subframes of radio frames using a physical uplink shared channel (PUSCH), where the subframes are divided into first and second sets. The circuitry may include a first power control loop utilized for the first set of subframes and a second power control loop utilized for the second set of subframes. The first power control loop may set transmission power levels for transmission over the PUSCH for the first set of subframes, and the second power control loop may set transmission power levels for transmission over the PUSCH for the second set of subframes. The circuitry may be configured with a first physical uplink control channel (PUCCH) for a first eNodeB and a second PUCCH for a second eNodeB to simultaneously communicate with the first and the second eNodeBs.

A method and apparatus are disclosed from the perspective of a device to perform sidelink transmission. The method includes the device being in RRC (Radio Resource Control)-connected mode in Uu link. The method also includes the device being configured to use at least DL (Downlink) pathloss for sidelink power control. The method further includes the device deriving a first DL pathloss value for determining an uplink transmit power of one specific kind of uplink transmission. In addition, the method includes the device determining or deriving a sidelink transmit power based on the first DL pathloss value. Furthermore, the method includes the device performing a sidelink transmission to other device(s) with the sidelink transmit power.

This disclosure provides systems, methods and apparatuses for transmission of synchronization signal blocks (SSBs) using adjusted transmit powers. In one aspect, a power offset may be configured for one or more sets of SSBs. The power offset may be configured to be applied for a set of SSBs based on a duplexing mode of one or more of a transmitter wireless node (that transmits an SSB) or a receiver wireless node (that receives the SSB). The duplexing mode may be based on whether the transmitter receiver node or the wireless receiver node is operating in a full-duplex mode or may be based on a resource configuration associated with a resource used to transmit the SSB. Some techniques and apparatuses described herein also provide signaling to support the transmission of SSBs using adjusted transmit powers, and techniques for receiving and processing SSBs that use adjusted transmit powers.

A method includes performing a first iteration of automated frequency coordination (AFC) using geospatial coordinates of a first access point at a site and a first margin of error to determine a first number of allowed channels for the first access point and performing a second iteration of AFC using the geospatial coordinates of the first access point and a second margin of error to determine a second number of allowed channels for the first access point. The first margin of error is lower than the second margin of error. The method also includes, in response to determining that a difference between the first number and the second number meets a threshold, instructing a second access point at the site to perform AFC using the second margin of error rather than the first margin of error.

An information handling system includes an antenna controller that may receive, from a platform sensor, platform sensor information as to a physical configuration usage mode, and receive, from a proximity sensor, information as to a part of a body of a user to an antenna. The antenna controller may also obtain a radio transmit power level value corresponding to the platform sensor information and to the proximity sensing information, send the radio transmit power level value to a radio via a serial interface, and reconfigure the antenna in response to the platform sensor information and the proximity sensing information. A radio may adjust a radio transmit power level to an adjusted radio transmit power level based on the radio transmit power level value.
