Abstract
Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for phase noise (PN) mitigation on multiple component carriers (CCs). A method that may be performed by a user equipment (UE) includes estimating impairments (e.g., common phase error (CPE) and/or inter-carrier interference (ICI)) caused by PN for only a first CC configured for the UE, wherein the first CC is configured with pilots for PN mitigation and mitigating the PN on each CC for all CCs configured for the UE based, at least in part, on the estimated impairments for the first CC.
Claims27
A method for wireless communication by a user equipment (UE), comprising:
- estimating impairments caused by phase noise (PN) for only a first component carrier (CC) configured for the UE, wherein the first CC is configured with pilots for PN mitigation;
- and
- mitigating the PN on each CC for all CCs configured for the UE based, at least in part, on the estimated impairments for the first CC;
- and
- transmitting, to a network entity, an indication of a capability of the UE to mitigate the PN on the each CC for all CCs configured for the UE when only one CC configured for the UE is configured with pilots for PN mitigation,
- wherein the first CC is configured with the pilots for PN mitigation in accordance with the capability and wherein the capability of the UE to mitigate the PN on the each CC for all CCs configured for the UE when only one CC configured for the UE is configured with pilots for PN mitigation varies per bandwidth part (BWP).
A method for wireless communication by a network entity, comprising:
- receiving, from a user equipment (UE), an indication of a capability of the UE to mitigate phase noise (PN) on each component carrier (CC) for all CCs configured for the UE when only one CC configured for the UE is configured with pilots for PN mitigation;
- and
- configuring a first CC configured for the UE with the pilots for PN mitigation in accordance with the capability, wherein the capability of the UE to mitigate the PN on the each CC for all CCs configured for the UE when only one CC configured for the UE is configured with pilots for PN mitigation varies per bandwidth part (BWP).
An apparatus for wireless communications by a user equipment (UE), comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor, the memory including instructions executable by the at least one processor to cause the apparatus to:
- estimate impairments caused by phase noise (PN) for only a first component carrier (CC) configured for the UE, wherein the first CC is configured with pilots for PN mitigation;
- and
- mitigate the PN on each CC for all CCs configured for the UE based, at least in part, on the estimated impairments for the first CC;
- and
- transmitting, to a network entity, an indication of a capability of the UE to mitigate the PN on the each CC for all CCs configured for the UE when only one CC configured for the UE is configured with pilots for PN mitigation,
- wherein the first CC is configured with the pilots for PN mitigation in accordance with the capability and wherein the capability of the UE to mitigate the PN on the each CC for all CCs configured for the UE when only one CC configured for the UE is configured with pilots for PN mitigation varies per bandwidth part (BWP).
An apparatus for wireless communications by a user equipment (UE), comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor, the memory including instructions executable by the at least one processor to cause the apparatus to:
- receive, from a user equipment (UE), an indication of a capability of the UE to mitigate phase noise (PN) on each component carrier (CC) for all CCs configured for the UE when only one CC configured for the UE is configured with pilots for PN mitigation;
- and
- configure a first CC configured for the UE with the pilots for PN mitigation in accordance with the capability, wherein the capability of the UE to mitigate the PN on the each CC for all CCs configured for the UE when only one CC configured for the UE is configured with pilots for PN mitigation varies per bandwidth part (BWP).
