Abstract: The present disclosure relates to a solution for repetition of physical downlink control channel (PDCCH). In particular, a first apparatus determines, within a frame in which a synchronization signal physical broadcast channel block (SS/PBCH block) is transmitted, a resource for at least one repetition of a PDCCH transmission based on a repetition factor configured for the PDCCH transmission and a multiplexing pattern associated with the SS/PBCH block and the PDCCH transmission. The first apparatus monitors, on the resource, the at least one repetition of the PDCCH transmission for obtaining control information from a second apparatus. In this way, it can reduce latency for the first apparatus and can also decrease a buffer size at the first apparatus

Abstract: According to an example aspect of the present invention, there is provided an apparatus, such as a user equipment, configured to transmit information in a physical uplink shared channel direction using, selectably, a first waveform or a second waveform, the second waveform having lower peak to average power ratio than the first waveform, provide, to a network node controlling a cell in which the apparatus is attached, first and second power headroom information, and select to either continue using the first waveform on the physical uplink shared channel, or to switch to using the second waveform on the physical uplink shared channel.

Abstract: In accordance with example embodiments of the invention there is at least a method and apparatus to perform determining a mismatch between at least one of a location or the number of physical resource blocks occupied by at least one of a plurality of physical uplink shared channel transmissions and at least one of a location or a number of physical resource blocks occupied by a physical uplink control channel for a physical uplink control channel transmission; and based on the determined mismatch, performing operations comprising at least one of: multiplexing uplink control information for the physical uplink control channel transmission with the at least one of the plurality of physical uplink shared channel transmissions, adapting the at least one of the location or the number of physical resource blocks of the physical uplink control channel transmission for matching the at least one of the location or the number of physical resource blocks occupied by the at least one of the plurality of physical uplink shared channel transmissions, or determining an information and communicate the information using at least one of downlink control information, medium access control—control element or higher layer signaling for overcoming at least the mismatch.

Abstract: Where large transport blocks are rate-matched and transmitted on each PUSCH segment using different redundancy versions (RVs), RV cycling with a small number of PUSCH segments might not cover the whole codeword, and/or rate-matching a large TBS across many PUSCH segments into the resource of a single PUSCH segment may lead to an effective coding rate of the self-decodable redundancy versions that is too high. To avoid these issues, the starting position of one or more RVs may be shifted by setting the starting position of a current RV to be the same as an ending position of a previous position, or by scaling the starting position by a value. Alternatively, these issues may be avoided by setting a new starting position for an RV based on the gap from the end of a previous RV to the start of a current RV.

Abstract: In accordance with example embodiments of the invention there is at least a method and apparatus to perform determining one duration of scheduled transmissions for at least one of physical uplink control channels or physical uplink shared channels; determining at least one actual duration over which power consistency and phase continuity can be maintained; applying one or more time-domain window duration based at least in part on the determined at least one actual duration to make the one or more time-domain window duration cover the one duration of the scheduled transmissions; and based on the determined more than one time-domain window duration, performing at least one of modulation or demodulation of the scheduled transmissions
