摘要： Certain examples of the present disclosure relate to tracking phase continuity, for example for De-Modulation Reference Signals for channel estimation using Joint Channel Estimation. Certain examples provide a User Equipment, UE, (110) comprising means (11) for: determining whether a coherence criterion has been met; selecting, based at least in part on the determination, a Reference Signal, RS, arrangement (301); and transmitting an RS (300) having the selected RS arrangement.

摘要： Disclosed is a method comprising receiving, from a first transmission and reception point of a wireless communication network, an indication for transmitting a random-access preamble to a second transmission and reception point of the wireless communication network after a beam switch from a source beam of the first transmission and reception point to a target beam of the second transmission and reception point; and transmitting the random-access preamble to the second transmission and reception point after the beam switch.

摘要： Example embodiments of the present disclosure relate to timing adjustment for uplink transmission, particularly in a high-speed scenario. A first device receives, from a second device, offset information indicating a difference in propagation delays between the first device and a third device experienced by the second device. The offset information is determined based on a time shifting value for a range of the difference in propagation delays. The time shifting value is associated with a switch from a beam associated with the first device to a beam associated with the third device. The third device is different from the first device. The first device transmits, to the second device, timing information indicating an amount of timing advance for transmission from the second device to the third device. The timing information is determined based on the time shifting value. Through this solution. UL transmission will be timing aligned.

摘要： According to an example aspect of the present disclosure, there is provided an apparatus comprising memory configured to store a set of probabilities of transitions between modulation symbols, the set of probabilities corresponding to a lower peak-to-average power ratio than a set of equal probabilities of transitions between modulation symbols, distribution matcher circuitry configured to process an input bit sequence into a symbol sequence, wherein frequencies of transitions between symbols in the symbol sequence conform to probabilities in the set of probabilities, a channel coder configured to generate parity bits of unity and negative unity from bit information obtained from the symbol sequence, grouping circuitry configured to assign symbols of the symbol sequence into groups each comprising two or more symbols, and multiplication circuitry configured to multiply each one of the groups with a corresponding one of the parity bits.
