The embodiments concern a method for encoding, comprising determining external data to generate one or more pictures, the generated one or more pictures to be used as reference pictures; generating loading instructions for the external data, the loading instructions indicating how the external data is to be processed; generating one or more predictors from corresponding one or more reference pictures; encoding coding units with the one or more predictors to generate encoded video data; and signaling the loading instructions to a decoder in or along a bitstream comprising the encoded video data. The embodiments also concern an encoder.

The present subject matter relates to a method comprising: communicating a frame to coordinate transmission of one or more streams by associated one or more second apparatuses of a set of apparatuses on a communication channel, the frame providing each second apparatus with control information to enable or disable transmission of a stream of the one or more streams by the second apparatus within at least one time window allocated for transmission on the communication channel by one or more third apparatuses of the set of apparatuses.

There is inter alia disclosed an apparatus for spatial audio encoding comprising: means for analysing a plurality of spatial audio parameter sets associated with a frame of one or more audio signals, wherein the plurality of spatial audio parameter sets are associated with a plurality of subframes, a plurality of frequency sub bands and a plurality of sound source directions for the frame of the one or more audio signals; and means for determining from the analysis of the plurality of spatial audio parameter sets at least one spatial audio parameter set for subframes of the frame of the one or more audio signals.

Apparatuses, methods, and computer programs for determining and using a radio network temporary identifier are disclosed. A method includes determining an offset; determining a first radio network temporary identifier based, at least partially, upon the offset; and using the first radio network temporary identifier for subsequently transmitting a message to a device.

Examples of the disclosure relate to optical apparatus for adjusting the size or position of an exit pupil. Example apparatus comprise a light guide configured to receive an input beam of light and provide a first expanded output beam of light and a second expanded output beam of light. The first expanded beam of light is directed in a first direction and the second expanded beam of light is directed in a second direction. The apparatus also comprises at least one optical component, spaced from the light guide, and configured to reflect at least part of the second expanded output beam of light towards the first direction to provide a combined exit pupil. The combined exit pupil comprises the first expanded beam of light and the second expanded beam of light wherein the combined exit pupil comprises a non-overlapping region.

Examples of the disclosure relate to optical apparatus that enable tracking of a user of the apparatus. The apparatus comprises a light guide arranged to enable light to be guided through the light guide via internal reflections, first in-coupling diffractive means configured to in-couple one or more input beams of light with a first wavelength range into the light guide, second in-coupling diffractive means configured to in-couple one or more input beams of light with a second wavelength range into the light guide, expanding diffractive means configured to expand the one or more input beams of light, and out-coupling diffractive means configured to out-couple the expanded beams of light from the light guide so as to provide a first exit pupil for the first wavelength range and a second exit pupil for the second wavelength range.

There is provided an apparatus comprising: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to: determine information associated with at least one of one or more channel state information, CSI, reports which are to be reported to an access node; and send said determined information associated with the at least one of the one or more CSI reports to the access node in one or more medium access control control elements, MAC CE, at least one of the one or more MAC CE providing a buffer status in addition to the determined information associated with the at least one of one or more CSI reports.

There is provided an apparatus comprising: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to: perform one or more measurements for one or more channel state information, CSI, reports; determine a size associated with at least one of the one or more CSI reports to be sent to an access node; and send a report to the access node, said report comprising information about the determined size associated with the at least one of the one or more CSI reports.

Examples of the disclosure relate to optical apparatus that can adjust the focus distance of images provided by the apparatus. The apparatus comprises a light guide configured to receive an input beam of light and provide an expanded output beam of light. The apparatus also comprises one or more optical components configured to adjust the expanded output beam of light. The apparatus also comprises adjustment means. The adjustment means are configured to adjust at least one of the light guide or the one or more optical components to enable a focus distance of an image provided by the apparatus to be adjusted. The adjustment means are synchronized with an image source so that the focus distance of the image provided by the apparatus is coordinated with an image provided by the image source.

Examples of the disclosure relate to optical apparatus, modules and devices for providing a head up display (HUD) or mediated reality headset. The optical apparatus can comprise a light guide configured to receive an input beam of light and provide an expanded output beam of light and one or more optical components configured to adjust the expanded output beam of light. At least two items of the light guide and the one or more optical components are arranged so that a first item has a first optical power in a first axis and a second item has a second optical power in a second axis. The second axis is different to the first axis and the optical powers of the respective items are configured to focus the expanded output beam of light.
