Detailed Description

As described above, if the configuration of the CR and CBR in the LTE system is still adopted in the NR system, the configuration of the CR and CBR cannot be adapted to the NR system.

In the embodiment of the invention, the value of the CR is determined through configuration information issued by a network side. And adjusting the value of the CR according to the value of the CR and the maximum channel occupancy rate, so that the value of the CR and the value of the CBR can adapt to an NR system.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

An embodiment of the present invention provides a method for acquiring a congestion control coefficient, which is described in detail below with reference to fig. 1 through specific steps.

Step S101, obtaining a CR measurement interval, a CBR measurement interval and a maximum channel occupancy.

In the embodiment of the present invention, the maximum channel occupancy (CR _ limit) may be associated with the subcarrier spacing, may be associated with spatial association information (spatialrelalationinfo), and may be associated with both the subcarrier spacing and the spatial association information. In practical applications, the spatial association information may also be referred to as spatial configuration (spatial configuration), spatial filter configuration (spatial filter configuration), spatial Tx parameter (spatial Tx parameter), or the like.

In practical applications, the spatial correlation information may refer to direction information corresponding to a beam (beam).

In a specific implementation, the network side may configure the measurement interval of the CR, the measurement interval of the CBR, and the CR _ limit for the ue in the configuration information. After receiving the configuration information issued by the network side, the user terminal can obtain the measurement interval of the CR, the measurement interval of the CBR, and the maximum channel occupancy configured by the network side.

The network side can configure the measurement interval of the CR for the user terminal through high-level signaling. After receiving the high-level signaling sent by the network side, the user terminal can acquire the measurement interval of the CR. The network side may select a value as the measurement interval of the CR from a candidate set of measurement intervals. The higher layer signaling sent by the network side may be Radio Resource Control (RRC) signaling.

For example, the alternative set of measurement intervals is 100ms, 125ms, 250ms, 500ms, 1000 ms. And the network side selects 250ms from the candidate set of the measurement interval as the measurement interval of the CR corresponding to the user terminal and sends the measurement interval to the user terminal through RRC signaling. After receiving the RRC signaling sent by the network side, the user terminal can know that the measurement interval of the CR is 250 ms.

The network side can also configure the measurement interval set of the CR for the user terminal through high-level signaling, and then indicate the measurement interval of the CR to the user terminal through the measurement interval indication information. The user terminal can obtain the measurement interval of the CR configured by the network side according to the high-level signaling and the measurement interval indication information issued by the network side.

In the embodiment of the present invention, the measurement interval indication Information may be Downlink Control Information (DCI) or MAC CE.

For example, through RRC signaling, the measurement interval set of the CR configured for the ue is as follows: {100ms, 125ms, 250ms, 500ms, 1000ms }. And the network side indicates the user terminal to select 500ms as the measurement interval of the CR through the DCI. After receiving the RRC signaling and the DCI, the ue may know that a measurement interval of the CR configured on the network side is 500 ms.

When the measurement interval indication information is MAC CE or DCI, the MAC CE or DCI may include 3-bit information for indicating the measurement interval of the CR that the user equipment should select.

For example, when the value of the 3-bit information is 000, the measurement interval of the corresponding CR is 100 ms; when the value of the 3bit information is 001, the measurement interval of the corresponding CR is 125 ms; when the value of the 3bit information is 010, the measurement interval of the corresponding CR is 250 ms; when the value of the 3-bit information is 011, the corresponding CR measurement interval is 500 ms; when the value of the 3-bit information is 100, the measurement interval of the corresponding CR is 1000 ms.

It can be understood that the above values are merely exemplary illustrations, and the number of bits and the bit value corresponding to the measurement interval indicating the CR to be selected may be set according to an actual application scenario, which is not described in detail in the embodiments of the present invention.

The network side can configure at least one value of a and b of the measurement interval of the CR for the user terminal through high-layer signaling. After receiving the high-level signaling sent by the network side, the user terminal can acquire at least one value of a and b in the measurement interval of the CR configured by the network side.

The network side may select a value in an alternative set of measurement intervals as a or b of the measurement interval of the CR. The network side may also select two values in a candidate set of measurement intervals as a and b of the measurement interval of the CR, respectively.

For example, the network side selects 100ms as a of the measurement interval of the CR from the candidate set {100ms, 125ms, 250ms, 500ms, 1000ms } of measurement intervals.

As another example, the network side selects 250ms as b of the measurement interval of the CR from the candidate set {100ms, 125ms, 250ms, 500ms, 1000ms } of measurement intervals.

The network side can send the selected a to the user terminal through the high-level signaling, can send the selected b to the user terminal through the high-level signaling, and can send a and b to the user terminal through the high-level signaling.

After determining a of the measurement interval of the CR, the network side may select b from the candidate set of measurement intervals, or may determine b according to a preset constraint condition. Accordingly, after determining b of the measurement interval of the CR, the network side may select a from the candidate set of measurement intervals, or may determine a according to a preset constraint condition. It should be noted that the selected a and b need to satisfy the preset constraint condition.

For example, in a high layer signaling sent by the ue to the ue, a measurement interval of the ue CR is indicated as { (100, 200) }. After receiving the high-level signaling, the ue knows that a corresponds to a measurement interval of the CR is 100ms and b corresponds to b is 200 ms.

The network side can also configure a set of a values and a set of b values corresponding to the measurement interval of the CR for the user terminal through a high-level signaling, and then indicate any one of a and b of the measurement interval of the CR to the user terminal through the measurement interval indication information. The user terminal can obtain any one of a and b of the measurement interval of the CR configured by the network side according to the high-level signaling and the measurement interval indication information issued by the network side, and can obtain the measurement interval of the CR.

For example, the network side configures the corresponding set of measurement intervals a of the CR for the ue through RRC signaling as {100ms, 125ms, 250ms, 500ms, 1000ms }.

The network side indicates the value of a of the measurement interval of the CR to the user terminal through the measurement interval indication information as 125 ms. The measurement interval indication information may include 3-bit information for indicating a of the measurement interval of the CR to the user terminal.

For example, when the value of the 3-bit information is 000, a of the measurement interval of the corresponding CR is 100 ms; when the value of the 3bit information is 001, a of the measurement interval of the corresponding CR is 125 ms; when the value of the 3bit information is 010, a of a measurement interval of the corresponding CR is 250 ms; when the value of the 3-bit information is 011, a of the measurement interval of the corresponding CR is 500 ms; when the value of the 3-bit information is 100, a of the measurement interval of the corresponding CR is 1000 ms.

The network side may also indicate a and b of the measurement interval of the CR to the user through the measurement interval indication information. The user terminal can obtain a and b of the measurement interval of the CR configured by the network side according to the high-level signaling and the measurement interval indication information issued by the network side, and can obtain the measurement interval of the CR.

For example, the network side configures, through RRC signaling, a set corresponding to a and b of a measurement interval of a CR for the user terminal as { (100, 200), (200, 100), (300, 100), (100, 300) }.

And the network side indicates the values of a and b of the measurement interval to the user terminal through the measurement interval indication information. The measurement interval indication information may include 2-bit information for indicating a and b of the measurement interval of the CR to the ue.

For example, when the value of the 2-bit information is 00, the corresponding values of a and b are (100, 200), where a is 100 and b is 200; when the value of 2bit is 01, the corresponding values of a and b are (200, 100), wherein a is 200 and b is 100; when the value of 2bit is 10, the corresponding values of a and b are (300, 100), wherein a is 300 and b is 100; when the 2bit value is 11, the corresponding values of a and b are (100, 300), where a is 100 and b is 300.

In a specific implementation, the network side may configure a measurement interval of the CBR for the ue through a high-level signaling. After receiving the high-level signaling sent by the network side, the user terminal can obtain the measurement interval of the CBR configured by the network side. The network side may select a value as the measurement interval of the CBR from a candidate set of measurement intervals. The higher layer signaling sent by the network side may be RRC signaling.

For example, the alternative set of measurement intervals is 100ms, 125ms, 250ms, 500ms, 1000 ms. And the network side selects 250ms from the candidate set of the measurement interval as the measurement interval of the CBR corresponding to the user terminal and sends the measurement interval to the user terminal through RRC signaling. After receiving the RRC signaling sent by the network side, the user terminal can know that the measurement interval of the CBR is 250 ms.

In specific implementation, the network side may also configure a measurement interval set of the CBR for the ue through a high-level signaling, and then indicate the measurement interval of the CBR to the ue through the measurement interval indication information. The user terminal can obtain the measurement interval of the CBR configured by the network side according to the high-level signaling and the measurement interval indication information issued by the network side.

In the embodiment of the present invention, the measurement interval indication information may be DCI or MAC CE.

For example, through RRC signaling, the measurement interval set of CBR configured for the ue at the network side is as follows: {100ms, 125ms, 250ms, 500ms, 1000ms }. And the network side indicates the user terminal to select 500ms as the measurement interval of the CBR through the DCI. After receiving the RRC signaling and the DCI, the ue may know that the measurement interval of the CBR configured on the network side is 500 ms.

In a specific implementation, when the measurement interval indication information is MAC CE or DCI, the MAC CE or DCI may include 3-bit information for indicating the measurement interval of the CBR that the ue should select.

For example, when the value of the 3-bit information is 000, the measurement interval of the corresponding CBR is 100 ms; when the value of the 3bit information is 001, the corresponding CBR measuring interval is 125 ms; when the value of the 3bit information is 010, the corresponding CBR measuring interval is 250 ms; when the value of the 3bit information is 011, the corresponding CBR measurement interval is 500 ms; when the value of the 3-bit information is 100, the measurement interval of the corresponding CBR is 1000 ms.

It can be understood that the above values are merely exemplary illustrations, and the number of bits and the bit value corresponding to the measurement interval of the CBR that should be selected by the indication may be set according to an actual application scenario, which is not described in detail in the embodiments of the present invention.

In particular implementations, the measurement interval of CR may be related to subcarrier spacing. The network side may agree with the user terminal in advance, and the measurement intervals of the CR are different for different subcarrier intervals.

In the embodiment of the present invention, the measurement interval of the CR corresponding to the subcarrier spacing selected according to the subcarrier spacing is: the method comprises the following steps of slot [ n-a, n + b ], wherein a and b are positive integers, slot n-a is the first slot before slot n, slot n-b is the second slot after slot n, and slot n is the current slot.

The subcarrier spacing may be 15kHz, 30kHz, 60kHz, 120kHz, 240kHz, or 480kHz, and the measurement interval of CR corresponding to different subcarrier spacings is described below.

In a specific implementation, when the Subcarrier Spacing (SCS) of the resource pool (resource pool) is 15kHz, or the SCS of the partial Bandwidth (BWP) is 15kHz, or the user terminal only counts the resources with SCS of 15kHz in the resource pool, the CR calculated in the current slot (slot n) is the ratio of all the resources used for transmitting data in the statistical interval slot [ n-a, n-1] and the statistical interval slot [ n, n + b ] to the number of all the resources, or the ratio of the resource of the transmission data with SCS of 15kHz in the statistical interval slot [ n-a, n-1] and the statistical interval slot [ n, n + b ] to the number of all the resources, or the ratio of all the resources with SCS of 15kHz for transmitting data in the statistical interval slot [ n-a, n-1] and the statistical interval slot [ n, n + b ] to the number of all the resources with SCS of 15 kHz. The value of CR may be counted according to the priority (priority) associated with each data transmission, and a and b satisfy the following condition: a + b +1 is 1000, a > 500, and n + b cannot exceed the index corresponding to the last slot scheduled by grant (grant).

In a specific implementation, the Resource used for transmitting data may be a subchannel (subchannel) used for transmission, where subchannel represents several Resource Blocks (RBs) that are consecutive in a time domain or a frequency domain. When the SCS of the resource pool is 15kHz, or the SCS of the BWP is 15kHz, or the user terminal only counts the resources with 15kHz in the resource pool, the CR calculated in the current time slot (slot n) is the ratio of the counting interval slot [ n-a, n-1] to all subchannels used as transmission data in the counting interval slot [ n, n + b ], or the ratio of the counting interval slot [ n-a, n-1] to all subchannels used as transmission data with 15kHz SCS in the counting interval slot [ n, n + b ], to all subchannels used as transmission data with 15kHz SCS in the counting interval slot [ n-a, n-1], or the ratio of the SCS of the counting interval slot [ n-a, n-b ] to all subchannels used as transmission data with 15 kHz.

When the SCS of the resource pool (resource pool) is 30kHz, or the SCS of the BWP is 30kHz, or the user terminal only counts the resources with SCS of 30kHz in the resource pool, the CR calculated in the current slot (slot n) is the ratio of all resources used for transmitting data in the statistical interval slot [ n-a, n-1] and the statistical interval slot [ n, n + b ], or the ratio of all resources used for transmitting data with SCS of 30kHz in the statistical interval slot [ n-a, n-1] and the statistical interval slot [ n, n + b ], to all resources used for transmitting data with SCS of 30kHz in the statistical interval slot [ n-a, n-1] to the total number of resources used for transmitting data with SCS of 30kHz in the statistical interval slot [ n, n + b ]. The value of CR may be counted separately according to the priority associated with each data transmission, while a and b satisfy the following condition: a + b +1 is 500, a > 250, and n + b cannot exceed the index corresponding to the last slot scheduled by grant (grant). The user terminal can select specific values of a and b according to specific application scenarios.

In a specific implementation, the resource used for transmitting data may be a subchannel used for transmission, where the subchannel represents several RBs consecutive in a time domain or a frequency domain. When the SCS of the resource pool is 30kHz, or the SCS of BWP is 30kHz, or the user terminal only counts the resource with 30kHz in the resource pool, the CR calculated in the current time slot (slot n) is the ratio of the counting interval slot [ n-a, n-1] to all subchannels used as transmission data in the counting interval slot [ n, n + b ], or the ratio of the counting interval slot [ n-a, n-1] to all subchannels used as transmission data with 30kHz SCS in the counting interval slot [ n, n + b ], to all subchannels used as transmission data with 30 kHz.
