Abstract: A method of estimating timing of at least one of the beginning and the end of a transmitted signal segment in the presence of time delay in a signal transmission channel. Each of a sequence of signal frames is provided with a pseudo-noise (PN) m-sequences, where the PN sequences satisfy selected orthogonality and closures relations. A convolution signal is formed between a received signal and the sequence of PN segments and is subtracted from the received signal to identify the beginning and/or end of a PN segment within the received signal. PN sequences are used for timing recovery, for carrier frequency recovery, for estimation of transmission channel characteristics, for synchronization of received signal frames, and as a replacement for guard intervals in an OFDM context.

Abstract: The present disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communications. A UE receives first information, the first information being used for indicating M DCI blind decoding(s); monitors a first-type radio signal respectively on each of S sub-band(s) in a first time-domain resource; and performs at most M1 DCI blind decoding(s) of the M DCI blind decoding(s) on the S sub-band(s) in the first time-domain resource. Herein, the first-type radio signal detected on the S sub-band(s) is used for determining the M1 DCI blind decoding(s) out of the M DCI blind decoding(s). The above method allows the base station to make dynamic adjustments to the UE's blind decoding on PDCCH resources according to LBT results, ensuring that sufficient PDCCH resources are available and not too many PDSCH resources are preempted, and that excessive blind decodings can be avoided.

Abstract: The disclosure provides a method and device used for node in wireless communication. The first node first receives a first reference signal and a second reference signal, then determines a first power within a range not greater than a first maximum power, and finally transmits a first radio signal with the first power; wherein the first maximum power is related to a measurement result against the first reference signal and is not related to a measurement result against the second reference signal. Through determining an upper limit of a transmitting power on a sidelink using a measurement result against a cellular network link, the disclosure can reduce interferences to the cellular network while ensuring the sidelink performance, and can optimize the transmitting power on the sidelink to reduce the power consumption of the terminal, thereby improving the overall performance of the system.
