A method for determining a transmit power in a coverage enhancement scenario and a device resolve a problem that the prior art lacks a solution to determining a transmit power of a preamble sequence in a random access process in the coverage enhancement scenario. The method includes: obtaining, by a terminal, configuration information that is used to determine a transmit power used for transmitting a signal at each coverage enhancement level; and determining, by the terminal according to the obtained configuration information, a transmit power used for transmitting the signal at a coverage enhancement level currently used by the terminal, so as to determine the transmit power used for transmitting the signal in the coverage enhancement scenario.

The present disclosure provides an electronic device and a method for wireless communication and a computer readable storage medium. The electronic device comprises: a processing circuit, configured to: allocate a spectrum resource for a spectrum allocation object of a first set managed by a first level spectrum management device; and to generate spectrum coordination information for a spectrum allocation object of a second set managed by a second level spectrum management device located on a lower level of the first level spectrum management device, so as to provide the same to the second level spectrum management device, wherein the spectrum coordinate information is used for coordination of spectrum allocation executed by the second level spectrum management device and spectrum allocation executed by the first level spectrum management device.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured with two sets of power control parameters may be signaled (e.g., via downlink control information (DCI)) as to which set of parameters to use for determining the transmission power on a sidelink channel. The UE may determine a transmit power for a sidelink message based on the indication included in the DCI. The base station may transmit the indication based on whether uplink or downlink communications are scheduled on resources that may overlap with resources used for transmission of the sidelink message.

A communication device that reduces power consumption is realized by appropriately setting a transmission output power value for DSC communication. A communication device (1) includes: an AIS receiving section (11) for receiving information related to an AIS; a DSC communication section (12) for performing DSC communication; and a transmission output power setting section (15c) configured to set a transmission output power value for communication performed on a conversation channel by the DSC communication section to a value corresponding to a distance, which is calculated based on the information, between the communication device and a communication target vessel.

Wireless service is provided to a service area using limited resources dynamically reallocated to maximize capacity in high demand regions. An antenna array transmits a plurality of downlink beams, each covering a respective region of a service area. An antenna management logic identifies a high demand region serviced by downlink beams transmitted from a first set of antennas at a first power level and a low demand region serviced by downlink beams transmitted from a second set of antennas at a second power level. The antenna management logic reconfigures the antenna array to provide the wireless service to the high demand region at a power level higher than the first power level, and to provide the wireless service to the low demand region at a power level lower than the second power level, such that the antenna array does not exceed a maximum power level available from a power supply.

An apparatus for receiving non-orthogonal transmissions in a wireless communication system includes a processor configured to determine a first superposed symbol from a plurality of superposed symbols, based on superposition information and a first set of decoding information, wherein the first superposed symbol is corresponding to a first user equipment. The processor generates a residual signal based on the first superposed symbol and the superposition information, and determines a second superposed symbol based on the residual signal and a second set of decoding information, wherein the second superposed symbol is corresponding to a second user equipment. The superposition information comprises a quantity of the plurality of superposed symbols and an ordering of the plurality of superposed symbols.

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 antenna control method selects as required one of two inbuilt antenna paths for optimal communication and includes a first transmission power of the antenna being acquired from one antenna path when a first and a second switch device are connected, and a second transmission power from a second antenna path when so connected. A determination is made on events or on a periodic basis as to whether the second transmission power is greater than or equal to the first transmission power, and the antenna path with greater power is selected for communication.

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.

The technology disclosed herein enhances the operation of a wireless access node to dynamically provide transmit power based on Reference Signal Receive Power (RSRP). In one implementation, a method of operating a wireless access node includes transmitting first signals with wireless communication devices using a first transmit power, and identifying RSRP values for the wireless communication devices. The method further includes identifying distances between the wireless access node and each wireless communication device, normalizing the RSRP values based on the distances, identifying a target RSRP based on the normalized RSRP values, and determining a second transmit power based on the target RSRP. The method further provides transmitting second signals to the wireless communication devices using the second transmit power.
