Peak to average power ratio (PAPR) reduction for repetition mode within single user, multiple user, multiple access, and/or MIMO wireless communication

摘要

Selective processing of one or more packets to be transmitted from a wireless communication device to another wireless communication device is effective to reduce the peak to average power ratio (PAPR) of the transmission. The one or more packets are transmitted via two or more sub-bands of an available transmission medium. The number of coefficients or factors within that sequence corresponds to the number of sub-bands via which the one or more packets are to be transmitted. Also, a phase ramp or time-domain cyclic shift may be added to one or more of the packets after having undergone multiplication by one of the coefficients or factors within the sequence.

主权项

1. A wireless communication device comprising:
a communication interface configured to receive a first packet via a first sub-band of a plurality of sub-bands and a second packet via a second sub-band of the plurality of sub-bands from another wireless communication device, wherein the first packet is multiplied by a sequence within the another wireless communication device to generate the second packet, wherein the sequence is effective to reduce or minimize peak to average power ratio (PAPR) of the first packet and the second packet, and wherein the sequence includes at least two coefficients selected from a set that includes 1, −1, j, and −j; and a processing circuitry configured to process the first packet and the second packet to recover information included therein.
