SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support phase noise reporting for constellation and waveform selection. Generally, the described techniques provide for mitigating the effects of noise on communications at a wireless device.

In some examples, a wireless device (e.g., such as a user equipment (UE)) may experience one or more types or sources of noise that may impact communications at the UE (e.g., from self-interference cause by communications at the UE, from one or more other wireless devices, phase noise, thermal noise, or otherwise additive noise sources). A second wireless device (e.g., a network entity, such as a base station or aspects thereof) may be able to help mitigate the effects of noise on communications received by the first wireless device by selecting one or more appropriate parameters for transmission from the second wireless device to the first wireless device. However, in order to do this efficiently, the network entity may use information about the noise experienced by the UE to appropriately select the parameters.

To provide the network entity with this information, the UE may transmit a noise report indicating a level of phase noise, a relative level of phase noise (e.g., compared to thermal noise), with one or more other details regarding the phase noise such that a network entity may more effectively select a waveform for downlink communications to improve overall performance at the UE by mitigating potential effects caused by high phase noise levels.

DETAILED DESCRIPTION

Some wireless communications systems may support communications in relatively higher frequency bands (e.g., FR2, FR4). Communications in these frequencies may be associated with higher levels of some types of noise, for example, such as phase noise. In some examples, an overall noise level associated with communications between a network entity and a user equipment (UE) may be used to determine the constellation or modulation and coding scheme for minimizing the effects of noise, but when the phase noise level is high (e.g., when communicating in higher frequency bands), a different communication configuration may be more appropriate given a same overall level of the noise. That is, some communications configurations may be more effective in the presence of high phase noise than others even when an overall noise level is the same.

A UE may transmit a noise report indicating a level of phase noise, a relative level of phase noise (e.g., compared to thermal noise), or one or more other details regarding the phase noise such that a network entity may more effectively select a waveform for downlink communications to improve overall performance at the UE by mitigating potential effects caused by high phase noise levels. The UE may be configured by the network entity to transmit the report based on a trigger or may transmit the report periodically. Based on the report, the network entity may select the most appropriate waveform for downlink communications. For example, the network entity may select one or more of the following options based on the report: square quadrature amplitude modulation (QAM) vs. non-square QAM, differential vs. non-differential modulation, or single carrier vs. multi-carrier waveforms. That is, the network entity may select the communication option that is most effective for the noise types or levels indicated in the report.

Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further described in the context of a process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to phase noise reporting for constellation and waveform selection.

For instance, an access network (AN) or RAN may include communications between access nodes (e.g., an IAB donor), IAB nodes104, and one or more UEs115. The IAB donor may facilitate connection between the core network130and the AN (e.g., via a wired or wireless connection to the core network130). That is, an IAB donor may refer to a RAN node with a wired or wireless connection to core network130. The IAB donor may include a CU160and at least one DU165(e.g., and RU170), in which case the CU160may communicate with the core network130over an interface (e.g., a backhaul link). IAB donor and IAB nodes104may communicate over an F1 interface according to a protocol that defines signaling messages (e.g., an F1 AP protocol). Additionally, or alternatively, the CU160may communicate with the core network over an interface, which may be an example of a portion of backhaul link, and may communicate with other CUs160(e.g., a CU160associated with an alternative IAB donor) over an Xn-C interface, which may be an example of a portion of a backhaul link.

In some examples of the wireless communications system100, a wireless device, such as a UE115may experience one or more types or sources of noise that may impact communications at the UE115(e.g., from communications performed by the UE115, from one or more other wireless devices such as another UE115, a network entity105, from one or more other sources, phase noise, thermal noise, or otherwise additive noise sources). A second wireless device, such as a network entity105may be able to help mitigate the effects of noise on communications received by the UE115by selecting one or more parameters for transmission from the network entity105to the UE115.

The UE115may transmit a noise report indicating a level of phase noise, a relative level of phase noise (e.g., compared to thermal noise), or one or more other details regarding the phase noise such that a network entity may more effectively select a waveform for downlink communications to improve overall performance at the UE by mitigating potential effects caused by high phase noise levels.

For example, the UE115may receive, from the network entity105, an indication that the UE115is to transmit a noise report that includes phase noise information. The UE115may determine phase noise information based on phase noise arising in communications between the UE and the network entity, and may transmit the noise report which includes the phase noise information. In some examples, based on receiving the noise report, the network entity105may select at least one parameter from a plurality of parameters for subsequent communications with the UE115and may transmit, e.g., to the UE115, one or more additional communications having at least one parameter that is determined by the network entity105based on the phase noise information in the noise report.

FIG.2illustrates an example of a wireless communications system200that supports phase noise reporting for constellation and waveform selection in accordance with aspects of the present disclosure. In some examples, wireless communications system200may implement aspects of wireless communications system100. Wireless communications system200may include a network entity105-aand a UE115-awhich may be examples of the corresponding devices as described with reference toFIG.1.

The wireless communications system200may support communications in relatively higher frequency bands (e.g., FR2, FR2x, FR4), which may utilize single-carrier waveforms for downlink communications (e.g., a DFT-S-OFDM waveform). In some examples, noise (e.g., phase noise) at these operating frequencies may be associated with higher levels than at other operating frequencies. In some examples, an overall noise level (e.g., including phase noise and other types of noise) may be used to determine a constellation or modulation coding scheme for communications between the UE115-aand the network entity105-a, but in some cases (e.g., high phase noise situations) one constellation may be more efficient for communications than other constellations even when an overall noise level is the same. For example, a non-square constellation may perform better than other constellations (e.g., square QAM) in the presence of strong phase noise.

In some examples, the UE115-amay provide information (e.g., relative strengths, relative magnitudes, relative levels, or absolute levels, strengths, or magnitudes), via uplink210, that is related to phase noise experienced at the UE115-awhile communicating (e.g., using higher frequency bands) with the network entity105-a(or, for example, one or more other wireless devices) which may help the network entity105-aincrease the efficiency of a downlink waveform transmitted via downlink205. For example, such information may assist the network entity105-ain making an informed decision or selection of a constellation parameter (e.g., type), amplitude modulation parameter, pulse modulation parameter, waveform parameter, or any combination thereof.

For example, the UE115-amay transmit a noise report (which, in some examples, may be referred to as a phase noise report) to the network entity105-avia uplink210. In some examples, the report may include noise levels, strengths, or noise types, among other examples. Additionally or alternatively, the report may include a type of phase noise (e.g., Gaussian or Weiner).

Based on receiving the report, network entity105-amay enhance a downlink waveform (e.g., in higher frequency bands) and may thereby increase performance at the UE115-a. For example, the network entity105-amay select one or more parameters for a downlink communication (e.g., waveform) such that the waveform may be efficiently received by the UE115-aeven in the presence of high noise or high phase noise. In some examples, the selection may be further based on a relative ratio of noise types of an overall noise level as indicated in the noise report.

The UE115-amay transmit a noise report to the network entity105-aincluding phase noise information and in some cases, additionally including noise information related to other additive noise sources (e.g., thermal noise). For example, the noise report may include a phase noise level, a thermal noise level, a relative (e.g., to one or more other sources of additive noise) phase noise level, a phase noise type (e.g., Gaussian noise, Weiner noise, or flicker noise), cutoff frequencies for portions of a phase noise function (e.g., cutoff frequencies for

f of a phase noise curve) as described with reference to noise diagram215.

Noise diagram215may show a relationship between phase noise in decibels per hertz (e.g., dBc/Hz) and a log scale frequency offset (e.g., fm). The noise diagram215may illustrate various functions of the relationship between phase noise and frequency offset. For example, a first set of frequency offsets may be associated with a phase noise of

a second set of frequency offsets may be associated with a phase noise of

a third set of frequency offsets may be associated with a phase noise of

and a fourth set of frequency offsets may be associated with a phase noise of f, among other examples. In some examples, the phase noise experienced by the UE115-aoperating in the third set of frequency offsets associated with a phase noise of 1/f may be referred to as flicker noise. In some examples, the frequency at which the phase noise function transitions from

to f, may be referred to as a corner frequency. In some examples, the phase noise experienced by the UE115-aoperating in the fourth set of frequency offsets associated with the phase noise, f may be referred to as “white” phase noise. Each phase noise function

may be associated with a phase noise cutoff frequency (e.g., the frequency at which the relationship between phase noise and frequency offset changes from one function to another). The noise diagram215may be an example of information provided to the network entity105-ain the noise report or may be an exemplary means for a UE to determine phase noise information to be included in the noise report.

For example, the UE115-amay transmit the noise report autonomously, or periodically, or sporadically, or based on a trigger (e.g., such as satisfying a noise threshold), or based on an indication from the network entity105-a, among other examples. For example, the network entity105-amay transmit signaling to the UE115-a, indicating that the UE115-ais to transmit a noise report. In some examples, the indication may further indicate whether the UE115-ais to transmit the noise report periodically or singularly corresponding to report request indications. In some examples, the signaling may be control signaling, and in some cases, may be channel state information (CSI)-reference signal (RS) signaling. The network entity105-amay receive the noise report via uplink210and may select a suitable (e.g., most effective, or efficient) waveform based one selecting one or more parameters for downlink communications with the UE115-aand may transmit one or more additional communications to the UE115-avia the downlink205using the one or more selected parameters.

FIG.3illustrates an example of a process flow300that supports phase noise reporting for constellation and waveform selection in accordance with aspects of the present disclosure. The process flow300may implement or be implemented by aspects of wireless communications system100or200. For example, the process flow300may illustrate operations between a UE115-band a network entity105-b, which may be examples of a UE115and a network entity105, as described with reference toFIG.1. In the following description of the process flow300, the operations between the UE115-band the network entity105-bmay be transmitted in a different order than the example order shown, or the operations performed by the UE115-band the network entity105-bmay be performed in different orders or at different times or by different devices. Some operations may also be omitted from the process flow300, and other operations may be added to the process flow300.

At305, the network entity105-bmay transmit signaling to the UE115-bthat indicates that the UE115-bis to transmit a noise report, for example, to the network entity105-b. In some examples, the signaling may be control signaling and, in some examples, may be CSI-RS signaling. In some examples, the signaling may indicate that the UE115-bis to transmit a noise report to one or more other devices.

At310, the UE115-bmay determine phase noise information. For example, the UE115-bmay determine a level (e.g., relative magnitude, absolute magnitude, amount) of the phase noise. In some examples, the UE115-bmay determine the level of phase noise based on an amount of phase noise in units of dBc/Hz. In some examples, the UE115-amay additionally determine information related to one or more other types of noise and the UE may determine a relative level of the phase noise with respect to the second type of noise, or a level of the second type of noise, or both, for inclusion in the phase noise report. In some examples, the second type of noise may be thermal noise.

Additionally or alternatively, the UE115-bmay determine a phase noise level associated with a frequency of communications between the UE115-band the network entity105-b, a cutoff frequency associated with a set of frequencies for the communications between the UE115-band the network entity105-b(e.g., a

cutoff, a

cutoff, a

cutoff, and a cutoff or starting frequency offset for white phase noise (e.g., flat phase noise areas), a rate of change of the phase noise as a function of frequency for the communications between the UE115-band the network entity105-b(e.g.,

flat phase noise areas), a type of rate of change of the phase noise as a function of frequency for the communications between the UE115-band the network entity105-b(e.g., Gaussian, Weiner), or some combination thereof, for inclusion in the noise report.

At315, the UE115-bmay transmit a noise report including the determine information about the phase noise, and additionally in some examples, the second type of noise that is different from the phase noise.

At320, the network entity105-bmay determine or select at least one parameter from a plurality of parameters for transmitting subsequent communications to the UE115-bbased on the information included in the noise report. For example, the network entity105-bmay select an amplitude modulation type (e.g., square QAM, or non-square QAM), a modulation type (e.g., a pulse modulation type, a differential modulation, a differential pulse modulation, a non-differential modulation, or a non-differential pulse modulation) or a type of waveform (e.g., DFT-S-OFDM, or OFDM (which may be an example of a multi-carrier waveform)), among other examples.

Optionally, at325, the network entity may transmit a second indication that at least one parameter for communications between the UE115-band the network entity105-bhas changed. For example, UE115-bmay receive the second indication and determine that a parameter associated with communications (e.g., previous communications) with the network entity105-bhas changed (e.g., by the network entity105-b) for one or more additional communications (e.g., subsequent communications) with the network entity105-b.

At330, the network entity105-bmay transmit, e.g., to the UE115-b, one or more additional communications (e.g., subsequent communications) having the at least one changed parameter as determined (e.g., selected) by the network entity according to the noise information included in the noise report.
