Abstract: A method for determining a transport block size includes: determining an overhead of a sidelink data channel PSSCH demodulation reference signal (DMRS) in a physical resource block (PRB) of a first time-frequency resource, where the first time-frequency resource includes a first time unit in time domain; and determining, based on the overhead of the PSSCH DMRS, a number of resource elements (REs) on the first time-frequency resource that are for data transmission, where the number of REs for data transmission is for determining a transport block size (TBS) of the sidelink data channel PSSCH. The method provides a combined gain of a plurality of transmissions of a same transport block, and supports DMRS configurations of different quantities of DMRS symbols in initial transmission and retransmission of one transport block.

Abstract: Amplifiers, amplification circuits, and phase shifters, for example, for flexibly adjusting an output phase to thereby meet a requirement of a constant phase on a link in a communications field, are provided. In one aspect, an amplifier includes first, second, and third MOS transistors. The first MOS transistor includes a gate separately coupled to a signal input end and a bias voltage input end, a source coupled to a power supply, and a drain separately coupled to sources of the second and third MOS transistors. A drain of the third MOS transistor is coupled to a ground, and a drain of the second MOS transistor is coupled to a signal output end. The bias voltage input end is configured to receive a bias voltage to adjust a phase difference between an input signal at the signal input end and an output signal at the signal output end.

Abstract: A first terminal apparatus sends K2 first reference signals to a second terminal apparatus in K1 directions. The first terminal apparatus determines that beams in the K1 directions all fail for N1 consecutive times. The first terminal apparatus sends P2 second reference signals to the second terminal apparatus in P1 directions. The first terminal apparatus determines, based on measurement results that are of the P2 second reference signals and that are from the second terminal apparatus, whether P1 beams corresponding to the P1 directions are available.
