Abstract: A sidelink control information sending and receiving method, a terminal apparatus, and a system are provided in this application, and may be applied to fields such as vehicle-to-everything (for example, V2X, LTE-V, or V2V), intelligent driving, and an intelligent connected vehicle. In a scenario in which second-stage SCI is not required in a sidelink communication system, a transmit end apparatus in sidelink communication indicates, by using first-stage SCI, a cyclic redundancy check bit corresponding to the first-stage SCI, or a reference signal used to demodulate the first-stage SCI, that the transmit end apparatus is not to send the second-stage SCI to a receive end apparatus. In this way, the transmit end apparatus may flexibly choose, based on a specific scenario of the sidelink communication, to use 2-stage SCI or 1-stage SCI, to avoid resource waste caused by using the 2-stage SCI in any scenario of the sidelink communication, thereby improving resource utilization efficiency.

Abstract: An oscillator and a clock circuit are disclosed. In an oscillator (100), a tail inductor connected to a cross-coupled transistor includes at least two inductors connected in parallel. Therefore, an inductance of the tail inductor is less than an inductance of any one of the inductors. This can address a design difficulty that a tail inductor with a smaller inductance needs to be used as an operating frequency of a VCO increases. The oscillator (100) includes a first cross-coupled transistor (121) and a first tail inductor (111). The first tail inductor (111) includes at least two inductors connected in parallel. The first tail inductor (111) is coupled to a source of the first cross-coupled transistor (121). The source of the first cross-coupled transistor (121) is coupled to a power supply or a ground through the first tail inductor (111).

Abstract: The present disclosure relates to integrated circuits. One example integrated circuit includes a first resonant circuit, a second resonant circuit, and at least one connection circuit. The first resonant circuit includes a first inductor, and the second resonant circuit includes a second inductor. The first inductor includes a first port and a second port, and the second inductor includes a third port and a fourth port. The at least one connection circuit is connected between at least one of the first port and the second port and at least one of the third port and the fourth port. Each connection circuit of the at least one connection circuit provides an electrical connection between two ports, where each of the two ports is connected to the connection circuit.

Abstract: A random access method, user equipment (UE), a base station, and a random access system, are provided to address relatively long service delay. In various embodiments, after downlink synchronization with a cell is obtained, UE can determine a preamble sequence of the UE in the cell, where the UE has not obtained uplink synchronization with the cell. The UE can then obtain service data and generate a scrambling code, and scramble the service data based on the scrambling code to obtain scrambled service data. The UE can then configure, based on a predetermined resource mapping relationship, time-frequency resources respectively occupied by the preamble sequence and the scrambled service data. The UE then sends on the configured time-frequency resources, the preamble sequence and the scrambled service data to a base station the cell belongs to and receives random access response sent by the base station based on the preamble sequence.

Abstract: The present invention discloses a cellular communication system, an inter-cell handover method for a UE, and a macro base station. The cellular communication system includes a macro base station and at least one micro base station within coverage of the macro base station. The macro base station is configured to: establish a control channel for a UE served by the micro base station; perform an access management operation for the UE served by the micro base station within the coverage of the macro base station; and receive a handover request of the UE and hand over the UE to another micro base station within the coverage of the macro base station. The micro base station is configured to establish a data channel for the accessed UE and perform data transmission with the UE.
