A wireless communication terminal apparatus wherein COMP communication can normally be performed without increasing the overhead of an upstream line control channel. In this apparatus, a spreading unit primarily spreads a response signal by use of a ZAC sequence established by a control unit. A spreading unit secondarily spreads the response signal, to which CP has been added, by use of a block-wise spread code sequence established by the control unit. The control unit controls, in accordance with sequence numbers and a hopping pattern established therein, the circular shift amount of the ZAC sequence to be used for the primary spread in the spreading unit and the block-wise spread code sequence to be used for the secondary spread in the spreading unit. The hopping pattern established in the control unit is a hopping pattern common to a plurality of base stations that CoMP-receive the response signal.

Systems and methods are described for exploiting inter-cell interference to achieve multiplexing gain in a multiple antenna system (MAS) with multi-user (MU) transmissions (“MU-MAS”). For example, a MU-MAS of one embodiment comprises a wireless cellular network with multiple distributed antennas operating cooperatively to eliminate inter-cell interference and increase network capacity exploiting inter-cell multiplexing gain.

Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for a single downlink control information (DCI) signal that supports multi-transmission reception point (TRP) transmissions from different TRPs (e.g., different 5G Node Bs or different antenna panels.) A user equipment (UE) receives a single DCI signal that includes a first transmission configuration indicator (TCI) state of a first TRP, a second TCI state of a second TRP, and a demodulation reference signal (DMRS) port indication value. The UE uses the DMRS port indication value to determine a first DMRS port and a first code division multiplexing (CDM) group of the first TCI state and a second DMRS port and a second CDM group of the second TCI state. The UE receives a multi-Physical Downlink Shared Channel (PDSCH) signal that includes multi-TRP transmissions, and uses the above determinations to decode data from the first and/or the second TCI states.

This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for grouping common DCI for CLI measurement and reporting. In a first aspect, a UE may receive DCI that is common to a group of UEs that includes the UE. The DCI may be configured to trigger at least one of an SRS transmission or a CLI measurement. The UE may transmit the SRS transmission and/or report the CLI measurement based on the DCI that is common to the group of UEs. In a second aspect, a base station may transmit at least one DCI that is common to the group of UEs to trigger the at least one of the SRS transmission or the CLI report for the group of UEs. The base station may receive the CLI report from at least a subset of UEs in the group of UEs.

A wireless communication system includes a first transmitter and a second transmitter. For a transmission or reception of data of a first user equipment and data of a second user equipment on resources shared by the first user equipment and the second user equipment, the first transmitter is configured for a superimposed non-orthogonal multiple access, NOMA, transmission or reception of a first data signal of the first user equipment and a second data signal of the second user equipment, and the second transmitter is configured for a superimposed non-orthogonal multiple access, NOMA, transmission or reception of a third data signal of the first user equipment and a fourth data signal of the second user equipment.

Interference in preamble signals and pilot signals in cooperative transmission using interference suppressing technology is avoided. A wireless apparatus for transmitting a wireless signal on which directivity control has been performed to stations in a wireless system including at least one wireless apparatus is provided with a known signal generating unit which generates a known signal to be added to the wireless signal, a weighting processing unit which performs weighting on the known signal generated by the known signal generating unit, and a wireless processing unit which transmits the known signal on which the weighting has been performed by the weighting processing unit.

A wireless communication terminal apparatus wherein CoMP communication can normally be performed without increasing the overhead of an upstream line control channel. In this apparatus, a spreading unit (214) primarily spreads a response signal by use of a ZAC sequence established by a control unit (209). A spreading unit (217) secondarily spreads the response signal, to which CP has been added, by use of a block-wise spread code sequence established by the control unit (209). The control unit (209) controls, in accordance with sequence numbers and a hopping pattern established therein, the circular shift amount of the ZAC sequence to be used for the primary spread in the spreading unit (214) and the block-wise spread code sequence to be used for the secondary spread in the spreading unit (217). The hopping pattern established in the control unit (209) is a hopping pattern common to a plurality of base stations that CoMP-receive the response signal.

Linerless labels are presented. A label includes a specific pattern or set of patterns of adhesive applied to one side of the label. The adhesive pattern(s) reduces contact between a cutter blade of a printer and the adhesive on the one side of the label. Moreover, the adhesive patterns reduce buildup of adhesive on the cutter blade and reduce buildup at specific locations on the cutter blade. That is, the adhesive patterns more evenly distribute adhesive buildup across the cutter blade. Consequently, the cutter blade can be used for a longer period of time before the cutter blade needs to be cleaned of the adhesive.
