Description

Physical resource block binding size determining method, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for determining a physical resource block bundling size, a terminal device, and a network device.

Background

Physical Resource Block (PRB) bundling transmission refers to that Physical Resource blocks (usually several consecutive Physical Resource blocks) in a certain range use the same codebook or beamforming parameters to transmit data, so that when a terminal receives data, it is ensured that multiple-PRB joint channel estimation can be performed in the range, and accuracy of channel estimation is enhanced, where a PRB bundling size (namely PRBbundling size) is used to indicate the number of PRBs bundled.

In a Radio access technology of a future mobile communication system, for example, in NR (New Radio access) of a fifth Generation (5th-Generation, abbreviated as 5G) mobile communication system, a Physical Downlink Shared Channel (PDSCH) before RRC (Radio Resource Control) is configured, a PRB bundling size is 2 for a multicast PDSCH and a unicast PDSCH. The set of Candidate Values (candidates) of the PRB bundling size may include one or more of 2, 4 and a configured bandwidth (i.e. scheduled BW), and when there is 1 Bit (i.e. Bit) of DCI (Downlink Control Information) indicating the PRB bundling size, the following configurations are supported:

DCI bit indication "1": selecting a value from one or two RRC configured candidate values;

DCI bit indicates "0": one RRC configured candidate is selected.

That is, the method for using 1 bit in DCI to indicate PRB bundling size is: when the value of the bit in the DCI for indicating the PRB bundling size is 0, the token PRB bundling size is one of Candidate Values (namely, Candidate Values), and when the value of the bit in the DCI for indicating the PRB bundling size is 1, the token PRB bundling size is one of the Candidate Values or one of two Values is selected (different from the value indicated when the value of the bit in the DCI for indicating the PRB bundling size is 0). However, there is no relevant solution in the prior art for how to determine the PRB bundle size when the bit value for indicating the PRB bundle size in the DCI is 1.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.

Referring to fig. 1, fig. 1 is a schematic diagram of a network structure to which a method for determining a bundling size of a physical resource block according to an embodiment of the present invention is applicable, and as shown in fig. 1, the method includes: terminal device 11 and network device 12, wherein terminal device 11 and network device 12 may be connected through a network, including but not limited to: a wide area network, a metropolitan area network, or a local area network.

In the embodiment of the present invention, the terminal Device 11 may be a mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal digital assistant (PDA for short), a Wearable Device (Wearable Device), or the like. The network device 12 may be an evolved Node B (eNB or eNodeB), a relay station or an access point, a base station in a 5G network (gNB), or a radio network controller on the network side, which is not limited herein.

In the embodiment of the present invention, a network device 12 configures an RRC (Radio Resource Control) signaling and a DCI (Downlink Control Information) for a terminal device 11, and sends the RRC signaling and the DCI to the terminal device 11, where the RRC signaling is configured with a candidate value set of a PRB (Physical Resource Block) bundling size, and the DCI includes a target bit for indicating a target PRB bundling size.

Specifically, when the candidate value set configured for the terminal device includes two candidate values and the value of the target bit used for indicating the target PRB bundling size in the DCI is 1, the network device 12 may determine the target PRB bundling size according to a preset indication rule.

Similarly, the terminal device 11 receives the RRC signaling and the DCI configured by the network device 12, and demodulates the RRC signaling and the DCI to obtain a candidate value set in the RRC signaling and a value of a target bit in the DCI for indicating a target PRB bundling size, where the candidate value set includes two candidate values and the value of the target bit is 1, and the target PRB bundling size may be determined according to a preset indication rule.

Optionally, the preset indication rule may be predefined by a protocol, or may be configured by a network device. When the preset indication rule is configured for the network device, the network device may send the preset indication rule through RRC signaling or other high-level signaling.

Optionally, the preset indication rule may include a mapping rule between a PRB bundle size and target information, where the target information may include, but is not limited to, a MIMO (Multiple Input Multiple Output) type, a REG (Resource Element Group) bundle size, a RBG (Resource Block Group) size, or a Subband (i.e., Subband) size, and the upper MIMO type may include single-user MIMO (i.e., SU-MIMO) or multi-user MIMO (i.e., MU-MIMO).

According to the embodiment of the invention, under the condition that the value of the target bit of the DCI is 1 and two candidate values exist in the candidate value set, the target PRB bundling size is determined according to the preset indication rule, and the target PRB bundling size is determined under the condition that the value of the target bit is 1 and the two candidate values exist, so that the terminal equipment can more accurately obtain the size of the PRB bundling value, and the accuracy of channel estimation is improved.

The embodiment of the invention provides a method for determining the bundling size of a physical resource block. Referring to fig. 2, fig. 2 is a flowchart of a method for determining a bundling size of a physical resource block according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:

step 201, obtaining a candidate value set of physical resource block PRB bundling size in a radio resource control RRC signaling configured by a network side and a value of a target bit used for indicating target PRB bundling size in downlink control information DCI.

In this embodiment of the present invention, the candidate value set of the PRB bundling size may include one or two of 2, 4 and a configured bandwidth (i.e. scheduled BW), and may be specifically configured by the network side. Specifically, when the value of the target bit is 0, it indicates that one candidate value for RRC configuration is selected, and when the value of the target bit is 1, one candidate value may be selected from one candidate value or two candidate values for RRC configuration.

Specifically, the terminal device may receive RRC signaling and DCI configured by the network side, and demodulate the RRC signaling and DCI to obtain a candidate value set in the RRC signaling and a value of a target bit in the DCI.

Step 202, when it is determined that the candidate value set includes two candidate values and the value of the target bit is 1, determining a target PRB bundling size according to a preset indication rule.

In the embodiment of the invention, when the candidate value set obtained by the terminal equipment through demodulation comprises two candidate values and the value of the target bit is 1, the target PRB bundle size may be determined according to a preset indication rule, for example, one candidate value may be randomly selected from two candidate values, or determining a pre-RRC configuration PRB bundle size (i.e. 2) as the target PRB bundle size, or determining a protocol-predefined PRB bundle size default parameter (e.g., when a value of target bits is 0 indicates a PRB bundle size of 2, the protocol-predefined PRB bundle size default parameter may be 4 or a configured bandwidth, etc.) as the target PRB bundle size, or determines a target PRB bundling size according to a mapping rule between the PRB bundling size and the target information, the target information may include, but is not limited to, MIMO type, REG bundling size, RBG size, subband size, or the like.

The method for determining the physical resource block bundling size of the embodiment of the invention obtains a candidate value set of the physical resource block PRB bundling size in a radio resource control RRC signaling configured at a network side and a value of a target bit used for indicating the target PRB bundling size in downlink control information DCI; when the candidate value set comprises two candidate values and the value of the target bit is 1, the target PRB bundling size is determined according to a preset indication rule, so that the target PRB bundling size is determined under the condition that the value of the target bit is 1 and the two candidate values exist, and the terminal equipment can accurately obtain the size of the PRB bundling value so as to improve the accuracy of channel estimation.

Optionally, the preset indication rule includes a mapping rule between a PRB bundling size and target information, where the target information includes a multiple-input multiple-output MIMO type, a resource element group REG bundling size, a resource block group RBG size, or a subband size, and the MIMO type includes single-user MIMO or multi-user MIMO.

In this embodiment of the present invention, the mapping rule between the PRB bundling size and the target information may be a corresponding relationship between the PRB bundling size and the target information, for example, may be a corresponding relationship table between the PRB bundling size and the target information.

Optionally, step 202, namely, the determining the target PRB bundling size according to the preset indication rule includes:

acquiring configuration parameters of current target information;

and determining the PRB bundling size corresponding to the configuration parameters of the current target information as the target PRB bundling size according to the mapping rule between the PRB bundling size and the target information.

In the embodiment of the present invention, when the target information is of the MIMO type, the configuration parameter of the current target information is also the configuration parameter of the current MIMO type, for example, the configuration parameter of the current MIMO type may be single-user MIMO or multi-user MIMO; when the target information is the REG bundling size, the configuration parameter of the current target information is also the configuration parameter of the current REG bundling size, for example, the configuration parameter of the current REG bundling size may be 2, 3, or 6, etc.; when the target information is the size of the RBG, the configuration parameter of the current target information is also the configuration parameter of the current RBG size, for example, the configuration parameter of the current RBG size may be 1, 2, 3, or 4, etc.; when the target information is the subband size, the configuration parameter of the current target information, that is, the configuration parameter of the current subband size, for example, the configuration parameter of the current subband size may be 6RB, 12RB, 24RB, or the like.

Specifically, after acquiring the configuration parameter of the current target information, the terminal device may determine, according to a mapping rule between the PRB bundling size and the target information, that the PRB bundling size corresponding to the configuration parameter of the current target information is the target PRB bundling size.

Optionally, to ensure that the terminal device may determine the target PRB bundling size, when obtaining the configuration parameter of the current target information fails, the determining the target PRB bundling size according to the preset indication rule further includes:

acquiring default parameters of target information, and determining the PRB bundling size corresponding to the default parameters of the target information as the target PRB bundling size according to the mapping rule between the PRB bundling size and the target information; or

Determining a default parameter of a PRB bundling size predefined by a protocol as the target PRB bundling size; or

Determining the target PRB bundling size from a candidate value randomly selected from the set of candidate values; or

Determining a PRB bundling size default parameter before RRC configuration as the target PRB bundling size; or

And determining a PRB bundling size default parameter configured on the network side as the target PRB bundling size.

In the embodiment of the present invention, the failure of the terminal device to acquire the configuration parameter of the current target information may be that the network side has not configured the target information for the terminal device.

In practical cases, the default parameters of the target information may be predefined in a protocol, so that when the network side does not configure the target information for the terminal device, the terminal device may use the default parameters of the target information predefined by the protocol. Therefore, when the configuration parameter of the current target information fails to be obtained, a default parameter of the target information predefined by a protocol may be obtained, and a PRB bundling size corresponding to the default parameter of the target information may be determined as the target PRB bundling size according to a mapping rule between the PRB bundling size and the target information.

Optionally, in the embodiment of the present invention, a default parameter of the PRB bundling size may also be predefined in the protocol, and when obtaining the configuration parameter of the current target information fails, the default parameter of the PRB bundling size predefined in the protocol may be used as the target PRB bundling size.

Optionally, in the embodiment of the present invention, when obtaining the configuration parameter of the current target information fails, the target PRB bundling size may be determined according to a candidate value randomly selected from the candidate value set.

Optionally, in the embodiment of the present invention, when obtaining the configuration parameter of the current target information fails, the default parameter of the PRB bundling size before RRC configuration (that is, 2) may be determined as the target PRB bundling size.

Optionally, in the embodiment of the present invention, a PRB bundling size default parameter may also be configured by the network side, and when obtaining the configuration parameter of the current target information fails, the PRB bundling size default parameter configured by the network side is used as the target PRB bundling size.

Optionally, a mapping rule between the PRB bundling size and the target information is predefined for a protocol or configured by the network side.

Optionally, the determining the target PRB bundling size according to the preset indication rule includes:

In this embodiment of the present invention, when it is determined that the candidate value set includes two candidate values and the value of the target bit is 1, a PRB bundling size default parameter predefined by a protocol may be directly determined as the target PRB bundling size, or a candidate value randomly selected from the candidate value set may be determined as the target PRB bundling size, or a PRB bundling size default parameter before RRC configuration may be determined as the target PRB bundling size, or a PRB bundling size default parameter configured on the network side may be determined as the target PRB bundling size, so as to ensure that a terminal device may determine the target PRB bundling size when it is determined that the candidate value set includes two candidate values and the value of the target bit is 1.

The following examples are provided to illustrate embodiments of the present invention:

referring to fig. 3, fig. 3 is a flowchart of a method for determining a bundling size of a physical resource block according to another embodiment of the present invention, as shown in fig. 3, including the following steps:

step 301, a UE (User Equipment) receives a candidate value set configured by RRC signaling and a DCI.

Specifically, the UE, i.e., the terminal device, includes target bits for indicating a PRB bundling size in the DCI.

Step 302, the UE demodulates the value of the target bit in the corresponding DCI and the candidate value set configured by the RRC signaling.

Step 303, when the value of the target bit in the DCI obtained by the UE through demodulation is 1 and two candidate values are configured in the RRC signaling, determining the current MIMO type.

Specifically, the MIMO type may include two configuration parameters, single-user MIMO (i.e., SU-MIMO) and multi-user MIMO (i.e., MU-MIMO). Alternatively, the current MIMO type may be determined according to, but not limited to, DMRS (Demodulation Reference Signal) indication.

Step 304, the UE determines the target PRB bundling size according to the PRB bundling size and the mapping rule between the MIMO types.

It is understood that the mapping rule between the PRB bundling size and the MIMO type may be predefined by a protocol, or may be configured on the network side.

For example, when the value of the target bit in the DCI is 1, and the candidate value set of the PRB bundling size may include a candidate value 1 and a candidate value 2, then in the mapping rule between the PRB bundling size and the MIMO type, the candidate value set may be a candidate value 1 corresponding to single-user MIMO, a candidate value 2 corresponding to multi-user MIMO, or a candidate value 2 corresponding to single-user MIMO, a candidate value 1 corresponding to multi-user MIMO.

Specifically, taking a candidate value 1 corresponding to a single-user MIMO and a candidate value 2 corresponding to a multi-user MIMO in a mapping rule between the PRB bundling size and the MIMO type as examples, when it is determined that a configuration parameter of the current MIMO type is a single-user MIMO, the target PRB bundling size may be determined as the candidate value 1, and when it is determined that a configuration parameter of the current MIMO type is a multi-user MIMO, the target PRB bundling size may be determined as the candidate value 2.

The embodiment of the invention implicitly indicates the PRB bundling size through the mapping rule between the PRB bundling size and the MIMO type, thereby saving the signaling overhead.

In practical cases, a PDCCH (Physical Downlink Shared Channel) REG bundling size (i.e. PDCCH REG bundling size) currently supports three sizes of 2, 3 and 6, and for a 1-symbol (i.e. 1-symbol) PDCCH, one of 2 or 6 may be configured by RRC; for a 2 symbol (i.e., 2-symbol) PDCCH, one of 2 or 6 may be configured by RRC; for a 3 symbol (i.e., 3-symbol) PDCCH, one of 3 or 6 may be configured through RRC. Thus, the PRB bundling size may be implicitly indicated with the PDCCH REG bundling size. Specifically, referring to fig. 4, fig. 4 is a flowchart of a method for determining a bundling size of a physical resource block according to another embodiment of the present invention, as shown in fig. 4, including the following steps:

step 401, the UE receives a candidate value set configured by RRC signaling and DCI.

Specifically, the DCI includes target bits for indicating a PRB bundling size.

Step 402, the UE demodulates the value of the target bit in the corresponding DCI and the candidate value set configured by the RRC signaling.

Step 403, when the value of the target bit in the DCI obtained by demodulation is 1 and the RRC signaling configures two candidate values, the UE may obtain the current REG bundling size and the number of PDCCH OFDM (Orthogonal Frequency Division Multiplexing) symbols (i.e., symbols).

Step 404, determining the current REG bundling size and the PRB bundling size corresponding to the PDCCH OFDM symbol number as the target PRB bundling size according to the PRB bundling size, the mapping rule between the PDCCH OFDM symbol and the REG bundling size.

It can be understood that the mapping rule among the PRB bundling size, the PDCCH OFDM symbol number, and the REG bundling size may be predefined by a protocol or may be configured by the network side.

Specifically, the mapping rule between PRB bundling size, PDCCH OFDM symbol and REG bundling size may be as shown in table 1:

TABLE 1

PDCCH OFDM symbol number	PDCCH REG bundling size	PRB bundling size
			1-symbol	2	Candidate value 1
1-symbol	6	Candidate value 2
			2-symbol	2	Candidate value 1
2-symbol	6	Candidate value 2
			3-symbol	3	Candidate value 1
3-symbol	6	Candidate value 2

As can be seen from table 1, the PRB bundling size is candidate value 1 when the current REG bundling size is 2 and the PDCCH OFDM symbol is 1-symbol, and the PRB bundling size is candidate value 2 when the current REG bundling size is 6 and the PDCCH OFDM symbol is 1-symbol.

The embodiment of the invention implicitly indicates the PRB bundling size through the mapping rule among the PRB bundling size, the PDCCH OFDM symbol and the REG bundling size, thereby saving the signaling overhead.

Referring to fig. 5, fig. 5 is a flowchart of a method for determining a bundling size of a physical resource block according to another embodiment of the present invention, as shown in fig. 5, including the following steps:

step 501, the UE receives a candidate value set configured by RRC signaling and DCI.

Step 502, the UE demodulates the value of the target bit in the corresponding DCI and the candidate value set configured by the RRC signaling.

Step 503, the UE demodulates to obtain that the value of the target bit in the DCI is 1 and the RRC signaling configures two candidate values.

Step 503, if the network side configures the RBG for the current BWP (Band Width Part), the UE may obtain the configuration parameter of the current RBG size, and determine the PRB bundling size corresponding to the configuration parameter of the current RBG size as the target PRB bundling size according to the mapping rule between the PRB bundling size and the RBG size.

Step 504, if the network side configures the sub-bandwidth for the current BWP, the UE may obtain the configuration parameter of the current sub-bandwidth size, and determine the PRB bundling size corresponding to the configuration parameter of the current sub-bandwidth size as the target PRB bundling size according to the mapping rule between the PRB bundling size and the sub-bandwidth size.

It is understood that the mapping rule between the PRB bundling size and the RBG size or the mapping rule between the PRB bundling size and the RBG size may be predefined by a protocol or may be configured on the network side.

The embodiment of the invention implicitly indicates the size of the PRB binding through the mapping rule between the size of the PRB binding and the size of the RBG or the mapping rule between the size of the PRB binding and the size of the sub-bandwidth, thereby saving the signaling overhead.

Referring to fig. 6, fig. 6 is a flowchart of a method for determining a bundling size of a physical resource block according to another embodiment of the present invention. As shown in fig. 6, the method comprises the following steps:

step 601, when a candidate value set of physical resource block PRB bundling size configured for the terminal device includes two candidate values and a value of a target bit used for indicating a target PRB bundling size in downlink control information DCI configured for the terminal device is 1, determining the target PRB bundling size according to a preset indication rule.

In the embodiment of the present invention, a network side may configure an RRC signaling and a DCI to a terminal device, and configure a candidate value set of a PRB bundling size for the RRC signaling, where the DCI includes a target bit for indicating a target PRB bundling size. Specifically, the candidate value set of PRB bundling size may include one or two of 2, 4 and configured bandwidth (i.e. scheduled BW). Specifically, when the value of the target bit is 0, it indicates that one candidate value for RRC configuration is selected, and when the value of the target bit is 1, one candidate value may be selected from one candidate value or two candidate values for RRC configuration.

Specifically, when the candidate value set of the PRB bundling size configured in the RRC signaling configured to the terminal device includes two candidate values and the value of the target bit is 1, the target PRB bundling size may be determined according to a preset indication rule, for example, one candidate value may be randomly selected from the two candidate values, or the PRB bundling size before RRC configuration (i.e. 2) is determined as the target PRB bundling size, or a protocol-predefined PRB bundling size default parameter (for example, when the value of the target bit is 0 indicates that the PRB bundling size is 2, the protocol-predefined PRB bundling size default parameter may be 4 or a configuration bandwidth, etc.) is determined as the target PRB bundling size, or the target PRB bundling size is determined according to a mapping rule between the PRB bundling size and target information, where the target information may include, but is not limited to MIMO type, and the target bit value is 1, REG bundling size, RBG size, or subband size, etc.

In the method for determining the bundling size of the physical resource block according to the embodiment of the present invention, when the candidate value set of the physical resource block PRB bundling size configured for the terminal device includes two candidate values and the value of the target bit for indicating the target PRB bundling size in the downlink control information DCI configured for the terminal device is 1, the target PRB bundling size is determined according to the preset indication rule, so that the target PRB bundling size is determined when the value of the target bit is 1 and there are two candidate values.

Optionally, the preset indication rule includes a mapping rule between a PRB bundling size and target information, where the target information includes a multiple-input multiple-output MIMO type, a resource element group REG bundling size, a resource block group RBG size, or a subband size, and the MIMO type includes a current user MIMO or a multi-user MIMO.

acquiring configuration parameters of current target information;

Specifically, after obtaining the configuration parameter of the current target information, the network side may determine, according to a mapping rule between the PRB bundling size and the target information, that the PRB bundling size corresponding to the configuration parameter of the current target information is the target PRB bundling size.

Optionally, to ensure that the network side may determine the target PRB bundling size, when obtaining the configuration parameter of the current target information fails, the determining the target PRB bundling size according to a preset indication rule further includes:

Determining a default parameter predefined by a protocol as the target PRB bundling size; or
