US 12,113,658 B1 · Modulation order selection associated with resiliency against spur impairment

Abstract

This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication performed by a user equipment (UE) includes receiving first and second indications of respective first and second sets of subcarriers associated with respective first and second modulation orders. Each subcarrier of the second set of subcarriers is associated with a first RF spur associated with the network node. The method further includes demodulating respective first and second signals concurrently received on the respective first and second sets of subcarriers in accordance with the respective first and second modulation orders. Other aspects and features are also claimed and described.

A method for wireless communication performed by a user equipment (UE), the method comprising:

receiving, from a network node, a first indication of a first set of one or more subcarriers of a bandwidth and a first modulation order associated with the first set of one or more subcarriers and a second indication of a second set of one or more subcarriers of the bandwidth and a second modulation order associated with the second set of one or more subcarriers, each subcarrier of the second set of one or more subcarriers being associated with a first radio frequency (RF) spur of a signal spectrum associated with the network node;
and
demodulating a first signal received on the first set of one or more subcarriers in accordance with the first modulation order and a second signal concurrently received on the second set of one or more subcarriers in accordance with the second modulation order.

A user equipment (UE) comprising:

one or more memories;
and
one or more processors coupled with the one or more memories and individually or collectively operable to:
receive, from a network node, a first indication of a first set of one or more subcarriers of a bandwidth and a first modulation order associated with the first set of one or more subcarriers and a second indication of a second set of one or more subcarriers of the bandwidth and a second modulation order associated with the second set of one or more subcarriers, each subcarrier of the second set of one or more subcarriers being associated with a first radio frequency (RF) spur of a signal spectrum associated with the network node;
and
demodulate a signal received on the first set of one or more subcarriers in accordance with the first modulation order and a signal concurrently received on the second set of one or more subcarriers in accordance with the second modulation order.
