摘要： A constant multiplier compiler model allows a modified canonical signed two's complement constant multiplier circuit design to be generated from a user specification of the desired constant. A netlist of a modified canonical signed two's complement constant multiplier circuit for computing a product of a multi-bit multiplicand and a multi-bit constant is automatically generated by modifying a netlist of a precursor signed two's complement constant multiplier circuit for computing a product of the multi-bit multiplicand and a multi-bit constant that is all ones. The number of zeros in the multi-bit constant is first maximized by converting the constant to modified canonical form. Then, for each zero in the multi-bit constant, a corresponding logical column of full adders is deleted and each output signal of each adder so deleted is logically connected to a corresponding output signal in a preceding logical column of adders. Two exceptions to the foregoing rule occur. In the case of a first logical column of adders having no preceding logical column of adders, each output signal of each adder deleted is logically connected to a bit of the multi-bit multiplicand. In the case of a logical row of adders receiving a most significant bit of the multi-bit multiplicand, each output signal of each adder deleted is logically connected to one of the most significant bit of the multi-bit multiplicand and logic zero. The method produces a minimum layout, minimizing silicon cost, and produces a high performance design with critical paths optimized in terms of time delay.

摘要： 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.

摘要： 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.
