Abstract: The disclosure is related to a method of generating a physical uplink control channel (PUCCH) in unlicensed spectrum, which is transmitted by a user equipment, the method comprising: - generating a PUCCH format 1 in an interlaced structure by: o determining a cyclic shift group (CSG) containing a first cyclic shift member (CSMf) and a plurality of subsequent cyclic shift members (CSMn), each cyclic shift member (CSM) being defined at least by a value and a position, by: - configuring the first cyclic shift member (CSMf) with a first indication related to the CSMf value and a second indication related to the CSMf position; - deriving the plurality of subsequent cyclic shift members (CSMn) based on the CSMf value and on the relative position between CSMf and each CSMn so as to define all CSM which are mutually different; o determining a first control sequence (Si cs(n)), in one OFDM symbol within OFDM symbols allocated for control sequence, by a first base sequence (S(n)), an acknowledgment information symbol (b) and the cyclic shift group; o determining a first reference sequence (Ri cs(n )), in one OFDM symbol within all OFDM symbols allocated for reference sequence, by the first base sequence (S(n)) and the cyclic shift group.

Abstract: According to some embodiments, a method includes selecting a length for an advanced television system committee (ATSC) 3.0 frame for transmission by a single frequency network (SFN) transmitter and aligning the SFN transmitter with a global positioning system (GPS) epoch. The method further includes storing geographical coordinates of the SFN transmitter and a corresponding SFN transmitter identification (TX ID) in a database. The method also includes encoding the SFN TX ID in a non-coherent symbol of a plurality of positioning navigation timing (PNT) symbols comprising a plurality of coherent symbols and the non-coherent symbol with orthogonal frequency-division multiplexing (OFDM) numerology to support positioning. The method further includes prepending the plurality of PNT symbols to the ATSC 3.0 frame to generate a modified ATSC 3.0 frame and transmitting the modified ATSC 3.0 using a SFN transmitter antenna of the SFN transmitter.

Abstract: Examples described herein include systems and methods which include wireless devices and systems with examples of mixing input data with coefficient data specific to a processing mode selection. For example, a computing system with processing units may mix the input data for a transmission in a radio frequency (RF) wireless domain with the coefficient data to generate output data that is representative of the transmission being processed according to a specific processing mode selection. The input data is mixed with coefficient data at layers of multiplication/accumulation processing units (MAC units). The processing mode selection may be associated with an aspect of a wireless protocol. Examples of systems and methods described herein may facilitate the processing of data for 5G wireless communications in a power-efficient and time-efficient manner.
