Description

Uplink control channel resource allocation method and device

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for configuring uplink control channel resources.

Background

In the field of wireless communication, in an unlicensed spectrum in a 52.6 GHz-71 GHz band, since a single RB (Resource Block) Resource adopted by a PUCCH (Physical Uplink Control Channel) may cause a limitation of transmission power, a Physical Resource that may occupy multiple RBs (Resource blocks) in a frequency domain is allowed. Since the number of RBs may change with the requirement of transmission power, signaling is required between the base station and the terminal to notify the number of RBs configured by the PUCCH, and the notification may be performed in a Radio Resource Control (RRC) signaling, a Downlink Control Information (DCI) signaling independent indication, and a physical layer PRI indication.

In the R17, in the PUCCH PF0/1/4 (PUCCH Format) enhancement problem of 52.6GHz to 71GHz, the increase of the number of RBs (N) is supported _RB ) For obtaining more Power under the PSD (Power Spectral Density) limit of the shared spectrum, the minimum RB number is 1, and the maximum RB number is supported

It is calculated by PSD limit of the transmitted signal, EIRP (Equivalent Isotropic Radiated Power) limit, antenna shaping gain of the UE (User Equipment or User terminal), and CM (Cubic Metric) value. Since the number of transmission RBs of PUCCH is not a fixed value but is from 1 to +>

And therefore, there is a need to determine the available value of the number of RBs supported in the system.

In the prior art, 1 RB is adopted for sending the current PUCCH PF0/1/4, and the configuration of the number of RBs is not needed. In the current existing scheme in the standard advancing process, the granularity of the RB number is 1, namely the step length is 1, so that the RB value is all possible integers. If the number of RBs is independently indicated by the DCI signaling, more bits are needed, and as a result, the control signaling overhead is larger. In addition, since DFT (Discrete Fourier Transform) pre-transformation is required in the symbol processing process of the PUCCH format4, discrete Fourier Transform (DFT) is also requiredTo meet PUCCH format4 additionally

Wherein alpha is ₂ ,α ₃ ,α ₅ Is a non-negative integer. In the prior art, a plurality of RBs can be used for transmitting a PUCCH PF2/3, and a resource configuration method is to configure a resource set of the PUCCH through RRC signaling, where the number of RBs corresponding to each resource set is a fixed value and ranges from 1 to 16, and the resource set is configured through RRC parameters. If the base station needs to adjust the value range of the number of RBs, the base station needs to notify all the RB number sets of the users again, thereby increasing the system burden.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a flowchart illustrating an uplink control channel resource allocation method according to an embodiment of the present disclosure, and as shown in fig. 1, an execution subject of the uplink control channel resource allocation method according to the embodiment of the present disclosure may be a terminal, for example, a mobile phone. The method comprises the following steps:

step 101, receiving configuration information of an uplink control channel resource sent by a network side device, wherein the configuration information at least comprises a resource starting position;

specifically, in this embodiment of the present application, a terminal first receives configuration information of an uplink control channel resource PUCCH, which is sent by a network side device. And the configuration information includes a resource start position, and may further include a first number of resource blocks RB occupied by the uplink control channel, an uplink control channel resource identification number, and the like. The starting position of the resource is the starting position of the RB resource block. The RB Resource Block may be a PRB (Physical Resource Block) or a VRB (Virtual Resource Block), which is not limited in this application.

And then the terminal determines the uplink control channel resource needed by the terminal according to the received resource initial position and by combining the first quantity of the Resource Blocks (RB) occupied by the uplink control channel.

102, receiving downlink control information DCI sent by the network side device, and determining a parameter index based on the DCI, where the parameter index is used to determine a first number of resource blocks RB occupied by an uplink control channel in a first resource set; the first resource set comprises a plurality of elements, the parameter index corresponding to each element is the index of each element in the first resource set, and each element corresponds to the number of RBs occupied by an uplink control channel; the plurality of elements included in the first resource set are determined based on the value range of the RB corresponding to the current subcarrier spacing SCS; wherein the resource starting position and the first number of resource blocks, RBs, occupied by the uplink control channel are used to determine the uplink control channel resource.

Specifically, in the embodiment of the present application, a corresponding RB value range is determined according to a current subcarrier SCS, for example, if the current subcarrier SCS =120KHZ, the corresponding RB value range is [1,8], and further, the number of elements included in the first resource set is determined according to the RB value range, for example, if the current RB value range is [1,8], the first resource set includes at most 8 elements, and includes at least one element. The value of each element represents the number of RBs occupied by the uplink control channel.

The method includes the steps that a terminal receives downlink control information DCI sent by network side equipment, and then parameter indexes of the number of uplink control channels (RB) are determined according to the DCI, the parameter indexes are called parameter indexes for short in the application, wherein the parameter indexes and the number of the RBs of the uplink control channels have one-to-one relation, and the number of the RBs of the uplink control channels corresponding to the terminal, namely the first number, can be found through the indexes. For example, when the value of the RB number (nrofPRBs) is 8, the corresponding parameter index is 7.

According to the uplink control channel resource allocation method provided by the embodiment of the application, the uplink control channel resource is pre-configured through the configuration information of the uplink control channel resource sent by the network side, the matched first resource set is determined in the configuration information through the downlink control information sent by the network side, and then the number of RBs in the uplink control channel which need to be occupied by access is determined. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS.

the method I comprises the following steps: configuring the first resource set based on RRC signaling, and indicating in an enumeration manner;

the second method comprises the following steps: and obtaining the first resource set based on the value range of the RB corresponding to the current subcarrier spacing SCS and a preset calculation rule.

Specifically, when the configuration mode is a first mode, the configuration of the first resource set may be an enumeration mode, and the set is directly configured based on RRC signaling.

There is an implementation scenario, for example, when SCS =120kHz, nrofPRBs is used to represent the number of RBs of the PUCCH channel, where PRB is taken as an example, and the corresponding first resource set value may be { nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs20, nrofPRBs24} or { nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs24, nrofPRBs32}; a parameter index of the number of PRBs (nrofPRBs) is an index of an element in the set, for example, index =0, corresponding to nrofPRBs1; index =1, corresponding to nroflrbs 2.

In another implementation scenario, the user may be allowed to,

all integers within the range. Wherein->

Is a PUCCH configurable minimum RB number at a certain SCS value, reserved>

Is the maximum RB number that the PUCCH can configure for a certain SCS value.

And when the configuration mode adopts the second mode, obtaining the first resource set based on the value range of the RB corresponding to the current subcarrier spacing SCS and a preset calculation rule.

Various values of the current subcarrier spacing SCS exist, such as 120khz,480khz,960khz, etc., and according to different SCS values, corresponding different RB value ranges are determined, and according to a preset calculation rule, a first resource set is further obtained through calculation.

The preset calculation rules mainly include two types: a first calculation formula and a second calculation formula.

The first calculation formula is:

The second calculation formula is:

K (dB) is the granularity of the transmission power adjustment of the PUCCH, i.e., the step size of the transmission power adjustment of the PUCCH, for the maximum RB number configurable for the PUCCH at the current subcarrier spacing SCS value.

According to the uplink control channel resource configuration method provided by the embodiment of the application, the configurable value of the PUCCH channel resource granularity is calculated by directly notifying the enumerated set of the number of RBs of the PUCCH, or the set of the number of RBs of the PUCCH is determined by setting a calculation formula of the number of RBs of the PUCCH and notifying related parameters, and the number of the RBs of the PUCCH is determined through DCI indication, so that the number of the RBs of the PUCCH can be flexibly configured.

Specifically, the receiving, by the terminal, the configuration information sent by the network side device includes: a resource starting position startingPRB, a parameter index and a channel resource identification number (pucch-resource id). This configuration information corresponds to scenario a.

The parameter index indicates an index for determining the number of RBs (nrofPRBs) of the PUCCH channels, and when the indexes are different, it is determined that there may be discontinuous values in the nrofPRBs.

Network side equipment, such as a base station, indicates pucch-Resource id to a terminal UE through a PRI (Physical Resource Indicator) in a scheduling signaling DCI, and the terminal UE determines nrofPRBs and startingPRB according to the pucch-Resource id and configuration information. And determining the PUCCH frequency domain resource position according to the parameters.

After receiving the configuration information corresponding to the scheme a, the terminal determines that each element in the first resource set is a discontinuous numerical value, and each element represents the number of RBs occupied by the uplink control channel, thereby implementing the configuration of the uplink control channel resources in a discontinuous section, and enabling the flexible configuration of the uplink control channel resources.

According to the uplink control channel resource configuration method provided by the embodiment of the application, the uplink control channel resource is pre-configured through the configuration information of the uplink control channel resource sent by the network side, and when the configuration information comprises the parameter index, the number of the configured PUCCH channels RB is discontinuous. And determining the matched first resource set in the configuration information through the downlink control information sent by the network side, and further determining the number of RBs in the uplink control channel which are occupied by the access. And the first resource set is determined based on the RB value range corresponding to the current sub-carrier SCS.

the determining a parameter index based on the DCI includes:

and determining the parameter index based on the explicit indication or implicit indication parameter index mode adopted by the DCI.

Specifically, the receiving, by the terminal, the configuration information sent by the network side device includes: a resource starting position startingPRB and a channel resource identification number (pucch-resource id). This configuration information corresponds to scheme B. Wherein, the configuration information has no parameter index (index)

The terminal receives downlink control information DCI sent by network side equipment (such as a base station), according to PRI in the DCI, the indication information corresponding to PUCCH-resource id is determined, the terminal UE finds out matched startingPRB in the configuration information according to the PUCCH-resource id, and determines parameter index according to the DCI, and then determines the number of RBs (nrofPRBs) of PUCCH channels, and further determines the position of PUCCH frequency domain resources.

Determining a parameter index based on the DCI, including: and determining the parameter index based on the explicit indication or implicit indication parameter index mode adopted by the DCI.

Specifically, the DCI may determine the parameter index by an explicit indication or an implicit indication, and when the indication is adopted, the DCI may be directly included in the parameter corresponding to the downlink control information DCI; when the implicit indication is adopted, the other parameters indirectly associated with the downlink control information DCI are determined.

determining the parameter index based on a bit field in the DCI;

the determining the parameter index based on the DCI by using the implicit indication parameter index includes:

Specifically, in the case that the DCI employs the display indication, the parameter index is determined based on a bit field in the DCI. Namely, a parameter index for determining the number of PRBs (nroflrbs) of a PUCCH channel is indicated by a bit field in DCI;

and under the condition that the DCI adopts the implicit indication, determining the parameter index based on the number of CCEs borne by the DCI. Namely, the parameter index for determining the number of PUCCH channels RB (nrofPRBs) is indicated by the number of Control Channel Elements (CCEs) carried by the DCI. The larger the number of CCEs, the larger the number of RBs corresponding to them.

According to the uplink control channel resource configuration method provided by the embodiment of the application, the uplink control channel resource is preconfigured through the configuration information of the uplink control channel resource sent by the network side, and when the configuration information does not include the parameter index, the parameter index can be determined through an explicit indication or implicit indication parameter index mode adopted by DCI. And determining the matched first resource set in the configuration information through the downlink control information sent by the network side, and further determining the number of RBs in the uplink control channel which are occupied by the access. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Therefore, flexible configuration of the uplink control channel resources is realized.

Specifically, the range of the parameter index is determined according to the bit width corresponding to the bit field in the DCI. For example, if the bit width of the DCI bit field is N, the value range of the index of the corresponding RB number (nrofPRBs) may be [0,2% ^N -1]. And the value of the parameter index is determined according to the value of the bit field in the DCI, and the bit width of the bit field in the DCI is determined according to the value of the current subcarrier SCS. For example, if the bit field has a bit width of 3 and the bit field has a value of 101, i.e., if the bit field has a value of 5, the corresponding parameter index has a value of 5.

According to the uplink control channel resource configuration method provided by the embodiment of the application, the uplink control channel resource is preconfigured through the configuration information of the uplink control channel resource sent by the network side, and when the configuration information does not include the parameter index, the parameter index can be determined through an explicit indication or implicit indication parameter index mode adopted by DCI.

And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Therefore, flexible configuration of the uplink control channel resources is realized.

Specifically, when the terminal receives the scheme B corresponding to the configuration information sent by the network side, the number of resource blocks (number of RBs) occupied by the uplink control channel indicated by each element in the first resource set in the enumeration manner may be flexibly configured as discontinuous data or associated numerical values.

According to the uplink control channel resource configuration method provided by the embodiment of the application, the uplink control channel resource is preconfigured through the configuration information of the uplink control channel resource sent by the network side, and when the configuration information does not include the parameter index, the parameter index can be determined through an explicit indication or implicit indication parameter index mode adopted by DCI. The corresponding resources may or may not be contiguous. And determining the matched first resource set in the configuration information through the downlink control information sent by the network side, and further determining the number of RBs in the uplink control channel which are occupied by the access. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Therefore, flexible configuration of the uplink control channel resources is realized.

Specifically, when the target subcarrier spacing SCS is an integer multiple of the current subcarrier spacing SCS, such as current subcarrier spacing SCS =120KHZ, the corresponding first resource set may be { nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs20, nrofPRBs24} or { nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs24, nrofPRBs32, and target subcarrier spacing SCS =480KHZ, the corresponding second set of resources is a subset of the first set of resources, such as { nrofPRBs1, nrofPRBs2, nrofPRBs4} or { nrofPRBs1, nrofPRBs4, nrofPRBs16, nrofPRBs20, nrofPRBs24} or { nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs20, nrofPRBs24}. The foregoing is merely exemplary.

And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Therefore, flexible configuration of the uplink control channel resources is realized.

Optionally, the method further includes:

The abnormal condition may include: if the terminal receives the configuration information, the parameter index in the configuration information cannot be analyzed normally, or the RB value range corresponding to the current subcarrier spacing SCS is generated according to the RB number obtained by calculating the parameter index, and at the moment, the default RB number is used as the number of RBs occupied by the uplink control channel.

Fig. 2 is a second flowchart of a method for allocating uplink control channel resources according to an embodiment of the present application; as shown in fig. 2, an embodiment of the present application provides a method for configuring uplink control channel resources, which is applied to a network device, and includes:

step 201, sending configuration information of uplink control channel resources to a terminal, wherein the configuration information at least comprises a resource starting position;

specifically, in this embodiment, a network side device, such as an access network device, sends configuration information of an uplink control channel resource to a terminal by a base station, where the configuration information includes a resource start position, and may further include a first number of resource blocks RB occupied by an uplink control channel, an uplink control channel resource identification number, and the like. The starting position of the resource is the starting position of the RB resource block. The RB Resource Block may be a PRB (Physical Resource Block) or a VRB (Virtual Resource Block), which is not limited in this application.

And then the terminal determines the uplink control channel resource required by the terminal according to the resource initial position sent by the network side equipment and by combining the first quantity of the Resource Blocks (RB) occupied by the uplink control channel.

Step 202, sending downlink control information DCI to the terminal, where the DCI is used to indicate a parameter index, and the parameter index is used to determine a first number of resource blocks RB occupied by an uplink control channel in a first resource set; the first resource set comprises a plurality of elements, the parameter index corresponding to each element is the index of each element in the first resource set, and each element corresponds to the number of RBs occupied by an uplink control channel; the plurality of elements included in the first resource set are determined based on the value range of the RB corresponding to the current subcarrier spacing SCS; wherein, the resource starting position and the first number of resource blocks RB occupied by the uplink control channel are used to determine the uplink control channel resource.

The network side device sends downlink control information DCI to the terminal, and is used for determining a parameter index of the number of the uplink control channels (RB) according to the DCI after the terminal receives the DCI, the parameter index is abbreviated as the parameter index in the application, the parameter index and the number of the RBs of the uplink control channels have a one-to-one relationship, and the number of the RBs of the uplink control channels corresponding to the terminal, namely the first number, can be found through the index. For example, when the value of the RB number (nrofPRBs) is 8, the corresponding parameter index is 7.

According to the uplink control channel resource configuration method provided by the embodiment of the application, the uplink control channel resource is preconfigured through the configuration information of the uplink control channel resource sent by the network side, the matched first resource set is determined in the configuration information through the downlink control information sent by the network side, and then the number of RBs in the uplink control channel which need to be occupied by access is determined. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS.

the first method is as follows: configuring the first resource set based on RRC signaling, and indicating in an enumeration manner;

There is an implementation scenario, for example, when SCS =120kHz, the number of PUCCH channels RB is represented by nrofPRBs, and the corresponding first resource set value may be { nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs20, nrofPRBs24} or { nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs24, nrofPRBs32}; a parameter index of the number of PRBs (nrofPRBs) is an index of an element in the set, for example, index =0, corresponding to nrofPRBs1; index =1, corresponding to nroflrbs 2.

In another implementation scenario, the user may be allowed to,

all integers within the range. Wherein->

Is a configurable minimum RB number, based on a certain SCS value, of the PUCCH>

Is the maximum RB number that the PUCCH can configure for a certain SCS value.

And when the configuration mode adopts a second mode, obtaining the first resource set based on the value range of the RB corresponding to the current subcarrier interval SCS and a preset calculation rule.

The first calculation formula is:

The network side equipment determines the corresponding configurable minimum RB number of the PUCCH according to the current subcarrier spacing SCS

And the maximum RB number->

And acquires through RRC signalingAnd obtaining the bit number N required by the number of the indicated PUCCH RBs, and determining each element in the first resource set based on a first calculation formula.

The second calculation formula is:

And the maximum RB number->

And setting granularity k (dB) of transmission power adjustment of the PUCCH, and determining each element in the first resource set based on the second calculation formula.

the DCI includes the channel resource identification number, where the channel resource identification number is used to determine the parameter index and the resource start position.

Specifically, the configuration information sent by the network side device includes: a resource starting position startingPRB, a parameter index and a channel resource identification number (pucch-resource id). This configuration information corresponds to scenario a.

Wherein the parameter index indicates an index for determining the number of RBs (nrofPRBs) of the PUCCH channel, and when the index is different, it is determined that there may be discontinuous values of nrofPRBs.

Network side equipment, such as a base station, sends downlink control information DCI to a terminal, and provides an indication pucch-resource id to a terminal UE through a PRI parameter in the DCI, so that the terminal UE determines nrofPRBs and startingPRBs according to the pucch-resource id and configuration information. And determining the PUCCH frequency domain resource position of the terminal according to the parameters.

And the network side equipment sends configuration information corresponding to the scheme A, wherein each element in the first resource set is a discontinuous numerical value, and each element represents the number of RBs occupied by the uplink control channel, so that the configuration of the uplink control channel resources in discontinuous intervals is realized, and the flexible configuration of the uplink control channel resources is realized.

According to the uplink control channel resource configuration method provided by the embodiment of the application, the uplink control channel resource is pre-configured through the configuration information of the uplink control channel resource sent by the network side, and when the configuration information comprises the parameter index, the number of the configured PUCCH channels RB is discontinuous. And determining the matched first resource set in the configuration information through the downlink control information sent by the network side, and further determining the number of RBs in the uplink control channel which are occupied by the access. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS.

Specifically, the configuration information sent by the network side device includes: a resource starting position startingPRB and a channel resource identification number (pucch-resource id). This configuration information corresponds to scheme B. Wherein, the configuration information has no parameter index (index)

Network side equipment, such as a base station, indicates PUCCH-resource id to UE through PRI in scheduling signaling DCI, the UE determines startingPRB according to PUCCH-resource id and configuration information, determines parameter index according to DCI, further determines number of PUCCH channels RB (nrofPRBs), and further determines PUCCH frequency domain resource position.

Optionally, the explicit indication manner adopted by the DCI for indicating the parameter index includes:

indicating the parameter index based on a bit field in the DCI;

and indicating the parameter index based on the number of CCEs borne by the DCI.

Specifically, when the DCI employs the display instruction, the network side device sends the DCI to the terminal, and the terminal determines the parameter index based on the bit field in the DCI. Namely, a parameter index for determining the number of RBs (nroflrbs) of the PUCCH channel through the bit field indication in the DCI;

and under the condition that the DCI adopts the implicit indication, the network side equipment sends the DCI to the terminal, and the terminal determines the parameter index based on the number of CCEs borne by the DCI. Namely, the parameter index for determining the number of PUCCH channels RB (nrofPRBs) is indicated by the number of Control Channel Elements (CCEs) carried by the DCI. The larger the number of CCEs, the larger the number of RBs.

The determining the parameter index based on a bit field in the DCI includes:

Specifically, the range of the parameter index is determined according to the bit width corresponding to the bit field in the DCI. For example, if the bit width of the DCI bit field is N, the index of the corresponding RB number (nrofPRBs) may be [0,2 ] ^N -1]. And the value of the parameter index is determined according to the value of the bit field in the DCI, and the bit width of the bit field in the DCI is determined according to the value of the current sub-carrier SCS. For example, if the bit width of the bit field is 3 and the bit field is 101, that is, the bit field is 5, the corresponding parameter index is 5.

According to the uplink control channel resource configuration method provided by the embodiment of the application, the uplink control channel resource is preconfigured through the configuration information of the uplink control channel resource sent by the network side, and when the configuration information does not include the parameter index, the parameter index can be determined through an explicit indication or implicit indication parameter index mode adopted by DCI. And determining the matched first resource set in the configuration information through the downlink control information sent by the network side, and further determining the number of RBs in the uplink control channel which are occupied by the access. And the first resource set is determined based on the RB value range corresponding to the current sub-carrier SCS. Therefore, flexible configuration of the uplink control channel resources is realized.

Specifically, when receiving the configuration information corresponding to the scheme B sent by the network side, the resource block number (RB number) occupied by the uplink control channel indicated by each element in the first resource set in the enumeration manner may be flexibly configured as discontinuous data or a linked numerical value.

Specifically, when the target subcarrier spacing SCS is an integer multiple of the current subcarrier spacing SCS, such as current subcarrier spacing SCS =120KHZ, the corresponding first set of resources may be { nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs20, nrofPRBs24} or { nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs24, nrofPRBs32}, while the target subcarrier spacing =480KHZ, the corresponding second set of resources may be a subset of the first set of resources, such as { nrofPRBs1, nrofPRBs2, nrofbs4, nrofPRBs4, nrofPRBs2, nrofPRBs4, nrofPRBs8, or { nrofPRBs1, nrofPRBs24, nrofPRBs8 }.
