Abstract: A Viterbi decoder generates a branch metric table from first and second data signals taken at two sample times and provides selected branch metrics to an add/compare/select circuit in response to branch indices from a branch index generator. The branch metrics in the branch metric table are the sixteen combinations of the sum of the first and second parallel data signals at first and second sample times and the inverse of such signals. The branch index generator generates the branch indices in response to a received state from the add/compare/select circuit, convolutional code polynomials and the possible states of a radix-4 trellis. The add/compare/select generates a survivor path decision based on the selected branch metrics.

Abstract: A constant multiplier compiler model allows a signed two's complement constant multiplier circuit design to be generated from a user specification of the desired constant. A netlist of a 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. 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: An apparatus for detecting a binary word each of the bits of which has the same binary value includes a plurality of logic groups, different ones of which receive different numbers of bits of the binary word. Each of the logic groups generates an output signal that is asserted if each of the number of bits received by the logic group has the same binary value. Carry ripple circuits series connected to form a carry ripple chain each receive an output signal from one of the logic groups. The carry ripple circuits also receive a carry ripple output signal from a previous carry ripple circuit and produce a carry ripple output signal for a succeeding carry ripple circuit. The carry ripple output signal is asserted when the output signal from the logic group is asserted and the carry ripple output signal from the previous carry ripple circuit is asserted.

Abstract: The present disclosure provides a method and a device in a first node for wireless communication. The first node first performs a monitoring on first-type signalings, in which K1 first-type signalings are detected; and then transmits a first radio signal in a first time-frequency resource set; each of the K1 first-type signalings is associated to the first time-frequency resource set; a first signaling is a last first-type signaling of the K1 first-type signaling; the first radio signal is used for determining the receiving of first-type signaling(s) associated to the first time-frequency resource set before the first signaling; or is used for determining the decoding of bit blocks scheduled by the K1 first-type signalings. With the above-mentioned designs, the present disclosure manages to address missed detection of sidelink scheduling signaling caused when a data receiver sends NACK-only feedback in V2X, thereby further improving the entire system performance.

Abstract: The present disclosure provides a method and device for use in wireless communication nodes. A first node receives first information; receives a first signaling; transmits X first-type radio signals, X being a positive integer greater than 1; and transmits second information, the second information comprising Y first-type information bit(s), Y being a positive integer; the first information is used to determine the second information; only the Y first-type information bit(s) comprised in the second information is(are) used to indicate whether at least one of the X first-type radio signals is correctly received; a target receiver of any of the X first-type radio signals is different from a target receiver of the second information. The method in the present disclosure effectively avoids the frequent reporting of the UE under the working mode of the base station controlling resource allocation, thus reducing the signaling overhead and retransmission delay of Uu Interface.

Abstract: The disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communication. The UE receives first information, and transmits a first radio signal using a first antenna port group; the first information is used for indicating a first offset set, and the first offset set includes K1 first-type offset(s); time domain resources occupied by the first radio signal start from a first time, a time interval between the first time and a second time is equal to a target offset; the UE selects the target offset from the K1 first-type offset(s) autonomously. The disclosure establishes a relationship between the first offset set and the first antenna port group, thus improving opportunities of beamforming based grant-free data transmission on unlicensed spectrum and reducing probability of collision, thereby improving spectrum efficiency and overall performances of the system.
