Title: Security print media and method of manufacture thereof
Inventor: ALAN KEEN
IPC: B42D25/45
Filed: 2015-09-29
Abstract: A security print medium 1 comprises a transparent or translucent polymer substrate 5 having first and second opposing surfaces 5a, 5b and a plurality of overlapping opacifying layers 6a, 6b, 6c, 7 disposed on the first and/or second surfaces of the polymer substrate, each of the opacifying layers being a layer of semi-opaque material disposed over substantially the whole area of the polymer substrate. In at least a region 9 of the substrate, a multi-tonal image is exhibited by the plurality of overlapping opacifying layers in combination with one another, at least when the security print medium is viewed in transmitted light. Each of the plurality of overlapping opacifying layers has gap(s) in which the semi-opaque material of the layer is absent, the gap(s) of each layer being defined in accordance with a different respective sub-image, the sub-images in combination defining the multi tonal image. As a result, the number of opacifying layers overlapping one another at any one location varies across the substrate, the resulting variation in optical density of the plurality of overlapping opacifying layers in combination with one another giving rise to the multiple tones of the multi-tonal image.

Title: Improvements in or relating to transmission without grant in New Radio
Inventor: GUANG LIU
IPC: H04W74/00
Filed: 2017-09-29
Abstract: Control signalling transmitted from a base station to one or more user equipments (UEs) has a variable payload size, the payload including feedback information for the UEs. The feedback information may be HARQ feedback, and each field may include UE identification information and a bitmap of Ack/Nack bits. The control message may further comprise a useful payload size (UPS) indicator which indicates a payload format. The payload may be pre-encoded and rate-matched to a predefined length, it may then be interleaved with the UPS and further encoded by a channel encoder. Alternatively, the UPS indicator may be encoded with part of the payload, such as part of the cyclic redundancy check (CRC). The scheme avoids the use of filler bits in fixed-size messages, using the space to enhance the reliability of useful fields instead. It may be used in association with grant free transmission in a 5G or New Radio network, the control signalling being group-common downlink channel information (DCI).

Title: Method, apparatus and arrangement for linearizing of a transmitter array
Inventor: NUUTTI TERVO
IPC: H04B7/06
Filed: 2017-12-05
Abstract: A method, apparatus or arrangement of linearizing a transmitter antenna array with a plurality of branches, comprising: determining pre-distortion coefficients based on a combined array response; and using the said coefficients for applying pre-distortion to an input signal that is transmitted to the branches of the array. The branches may be non-linear and these branches may purposively be made different to obtain varying responses of the non-linear branches over the transmitter array. The feedback structure may model an array response to the predetermined direction signal of the array. A feedback circuit 80 with a plurality of feedback branches can be used for feeding back individual response signals at the outputs of the non-linear branches through phase shift and attenuation units of the feedback branches, and for combining the response signals at the outputs of the feedback branches, wherein phase shift and attenuation of each feedback branch is controlled to model a transmission channel of the individual response signals to a receiver in a predetermined direction. Thereby, a linearization scheme can be provided, which utilizes variations over the non-linear branches to linearize the whole array with a single pre-distortion input by relatively simple pre-distortion models.
