Abstract: 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.

Abstract: The disclosure provides a method and a device in a first node for wireless communication. The first node first monitors a first signaling and a second signaling in a first time-frequency resource set, then judges whether to transmit a first radio signal according to a monitoring result of the first signaling, and finally transmits the first radio signal in a second time-frequency resource set, when judging to transmit the first radio signal; wherein the second signaling is not detected in the first time-frequency resource set, a signaling format corresponding to the second signaling is used for scheduling of a data signal. Through designing the first signaling and the second signaling, the disclosure solves the problem of missing detection of a sidelink scheduling signaling in Vehicle-to-Everything (V2X) caused when a data receiver only feeds back incorrect reception, thereby improving the overall performance of the system.

Abstract: The present disclosure discloses a method and device in UE and base station used for wireless communications. A UE transmits a first radio signal, the first radio signal indicating a first reference signal out of M reference signals; and monitors a first signaling in each of W time-frequency resource block(s). Herein, at least one reference signal of the M reference signals is transmitted by a first serving cell, and the first serving cell is not added by the UE; the UE assumes that a transmission antenna port of the first signaling is Quasi-Co-Located with a transmission antenna port of the first reference signal; W is a positive integer, and M is a positive integer greater than 1. Such method can be employed to avoid delay and service interruption brought about by cell handover.
