Fields

CREATOR

public static final Creator<CellSignalStrengthNr> CREATOR

Implement the Parcelable interface

Public methods

describeContents

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
`int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

equals

public boolean equals (Object obj)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

It is reflexive: for any non-null reference value x, x.equals(x) should return true.
It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
`obj`	`Object`: the reference object with which to compare.

Returns
`boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

getAsuLevel

public int getAsuLevel ()

Get the RSRP in ASU. Asu is calculated based on 3GPP RSRP. Refer to 3GPP 27.007 (Ver 10.3.0) Sec 8.69

Returns
`int`	RSRP in ASU 0..97, 255, or UNAVAILABLE

getCsiCqiReport

public List<Integer> getCsiCqiReport ()

Return a list of CSI channel quality indicators (CQI) for all subbands. If the CQI report is for the entire wideband, a single CQI index is provided. If the CQI report is for all subbands, one CQI index is provided for each subband, in ascending order of subband index. If CQI is not available, the CQI report is empty. Reference: 3GPP TS 138.214 section 5.2.2.1.

Returns
`List<Integer>`	the CQIs for all subbands if available or empty list if unavailable. This value cannot be `null`. Value is between 0 and 15 inclusive

getCsiCqiTableIndex

public int getCsiCqiTableIndex ()

Return CSI channel quality indicator (CQI) table index. There are multiple CQI tables. The definition of CQI in each table is different. Reference: 3GPP TS 138.214 section 5.2.2.1.

Returns
`int`	the CQI table index if available or `UNAVAILABLE` if unavailable. Value is between 1 and 3 inclusive

getCsiRsrp

public int getCsiRsrp ()

Reference: 3GPP TS 38.215. Range: -140 dBm to -44 dBm.

Returns
`int`	CSI reference signal received power, `CellInfo#UNAVAILABLE` means unreported value.

getCsiRsrq

public int getCsiRsrq ()

Reference: 3GPP TS 38.215. Range: -20 dB to -3 dB.

Returns
`int`	CSI reference signal received quality, `CellInfo#UNAVAILABLE` means unreported value.

getCsiSinr

public int getCsiSinr ()

Reference: 3GPP TS 38.215 Sec 5.1.*, 3GPP TS 38.133 10.1.16.1 Range: -23 dB to 23 dB

Returns
`int`	CSI signal-to-noise and interference ratio, `CellInfo#UNAVAILABLE` means unreported value.

getDbm

public int getDbm ()

Get the SS-RSRP as dBm value -140..-44dBm or UNAVAILABLE.

Returns
`int`

getLevel

public int getLevel ()

Retrieve an abstract level value for the overall signal quality.

Returns
`int`	Value is between SIGNAL_STRENGTH_NONE_OR_UNKNOWN and SIGNAL_STRENGTH_GREAT inclusive

getSsRsrp

public int getSsRsrp ()

Reference: 3GPP TS 38.215. Range: -140 dBm to -44 dBm.

Returns
`int`	SS reference signal received power, `CellInfo#UNAVAILABLE` means unreported value.

getSsRsrq

public int getSsRsrq ()

Reference: 3GPP TS 38.215; 3GPP TS 38.133 section 10 Range: -43 dB to 20 dB.

Returns
`int`	SS reference signal received quality, `CellInfo#UNAVAILABLE` means unreported value.

getSsSinr

public int getSsSinr ()

Reference: 3GPP TS 38.215 Sec 5.1.*, 3GPP TS 38.133 10.1.16.1 Range: -23 dB to 40 dB

Returns
`int`	SS signal-to-noise and interference ratio, `CellInfo#UNAVAILABLE` means unreported value.

hashCode

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int`	a hash code value for this object.

toString

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String`	a string representation of the object.
