Implementations relate to configuration of wireless communication signals between devices. In some implementations, a method includes determining a transmission scenario associated with transmission of wireless signals of a particular wireless communication protocol from a first device to a second device. The transmission scenario specifies one or more transmission characteristics for the signal transmission. A test message is sent wirelessly from the first device to the second device according to the transmission scenario, and a reply message is received from the second device in response to test message. The reply message includes one or more signal quality indicators that indicate a signal quality of the test message. The transmission scenario is selected as a designated scenario based on the signal quality indicators, and data is wirelessly transmitted from the first device to the second device according to the designated scenario.

Embodiments of this application provide an uplink measurement management method. The method includes: A radio access network (RAN) device receives a first message from a positioning device, where the first message is used by the positioning device to request the RAN device to perform uplink measurement, and the first message includes a measurement periodicity and a measurement amount. The RAN device measures an uplink sounding reference signal (SRS) of a terminal device based on the measurement periodicity and the measurement amount, and sends a first response to the positioning device, where the first response includes a measurement result of the uplink SRS.

A method for aligning test environments is provided. The method inlcudes: measuring, by a measurement device located in an anechoic chamber, a standard signal transmitted from a base station simulator and went through to a channel emulator, then output with noise added inside the channel emulator, to multiple antennas within the anechoic chamber; obtaining, by a computing device, measurement information based on the standard signal and the noise transmitted from the measurement device; determining, by the computing device, whether the measurement information is within a predetermined range of a target value; and transmitting, by the computing device, a control signal to the channel emulator to adjust the noise output from the channel emulator so that the computing device obtains desired measurement information based on the standard signal and the adjusted noise when the measurement information is not within the predetermined range of the target value.

A method and an apparatus for transmitting a physical layer protocol data unit that can provide a short training field sequence for a larger channel bandwidth. The short training field sequence has a smaller peak-to-average power ratio PAPR and better performance. The method includes: generating a physical layer protocol data unit PPDU, where the PPDU includes a short training field, a length of a frequency domain sequence of the short training field is greater than a first length, and the first length is a length of a frequency domain sequence of a short training field of a PPDU transmitted on a channel with a bandwidth of 160 MHz; and sending the PPDU on a target channel, where a bandwidth of the target channel is greater than 160 MHz.

A method for testing terminals includes determining a quantity of terminals to be tested; testing each terminal to be tested in a testing environment and obtaining a quantity of testing results; each testing result includes an actual transmitting power and/or a receiving signal strength; obtaining a first fitting function based on the actual transmitting power, and/or obtaining a second fitting function based on the receiving signal strength; and controlling a target terminal to transmit signals, calculating an actual transmitting power of the target terminal by the first fitting function, and/or controlling the target terminal to receive signals, calculating a receiving signal strength of the target terminal by the second fitting function. A computer apparatus and a non-transitory computer readable medium for testing terminals are also disclosed.

Methods of sensory input integrity attestation are provided. Artifacts included within devices under test inject a known noise signal into the output signal of one or more output devices that are detectable by one or more input devices (i.e., sensors) of an embedded device, and monitor the received input data. By comparing the received signal against the expected noise signal, attestation of the validity of sensory input data is possible. Such sensory input data attestation is capable either locally or using a remote attestation device with knowledge of the expected data stream.
