Technical field

The present invention relates to the field of communication technology, and in particular to a method for obtaining control information, an instruction method, a terminal and a network device.

Background technique

When a terminal establishes a communication link with a Transmission Reception Point (TRP) and performs an uplink transmission, as the terminal moves and the surrounding wireless channel environment changes, the uplink channel is attenuated or even blocked. A communication interruption occurs, thereby destroying the normal uplink transmission performance. In order to improve the reliability of uplink transmission, the terminal can establish communication links with multiple TRPs at the same time. For example, the physical uplink shared channel (PUSCH) is repeatedly sent on multiple TRPs. Once one of the communication links has a problem, the other links can continue to work, improving the robustness of the PUSCH.

The terminal sending PUSCH is based on the received radio resource control (Radio Resource Control, RRC) and physical downlink control channel (Physical Downlink Control Channel, PDCCH) related signaling carried. In the design of the fifth-generation mobile communication 5G, Downlink Control Information (DCI) formats (formats) 0-0, 0-1, and 0-2 are respectively used to indicate the information transmitted by the uplink PUSCH, but these formats All are based on single TRP scheduling. If you want to indicate support for PUSCH transmission on multiple TRPs in one DCI, you need to expand the control information in the existing DCI format, such as the Transmit Precoding Matrix Indicator (TPMI) and the transmitted data stream. The number of (layers) is related to the channel conditions of different TRPs and needs to be configured independently and cannot be shared. This design will increase the DCI signaling overhead.

As shown in FIG. 2, an embodiment of the present invention provides a method for acquiring control information, which is applied to a terminal, and the method includes:

Step 201: Acquire part of the control information for transmitting the physical uplink shared channel PUSCH according to preset rules or instruction signaling sent by the network device.

The foregoing indication signaling may be high-level signaling, and the high-level signaling includes at least one of media access layer control unit MAC CE signaling and radio resource control RRC signaling.

The above-mentioned partial control information includes at least one of the following:

TPMI;

number of layers;

TPMI offset;

Transmission layer;

SRS Resource Indicator (SRS Resource Indicator, SRI);

Power control parameters.

In an embodiment, the above-mentioned method for acquiring control information may further include: acquiring other (remaining) part of the control information for transmitting the PUSCH according to the DCI. In this way, the terminal obtains part of the control information for transmitting the PUSCH through preset rules or instruction signaling, and then obtains another part of the control information through DCI, and the terminal transmits the PUSCH according to the two parts of control information.

The method for acquiring control information in the embodiment of the present invention acquires part of the control information for transmitting the physical uplink shared channel PUSCH according to preset rules or the instruction signaling sent by the network device, instead of acquiring the control information for transmitting the PUSCH completely through DCI , Which greatly reduces the DCI signaling overhead.

Further, acquiring part of the control information for transmitting the physical uplink shared channel PUSCH according to the instruction signaling sent by the network device includes:

Acquire the first reference control information for transmitting PUSCH according to the instruction signaling sent by the network device;

According to the bit information in the first reference control information and the downlink control information DCI, obtain part of the control information for transmitting the PUSCH, and the bit information is used to indicate the second reference control information for transmitting the PUSCH.

As a first optional implementation manner, the foregoing first reference control information includes: at least a subset of terminal antenna coherence characteristic capability information; and the second reference control information includes a transmission precoding matrix indicator TPMI associated with the subset. Or, the second reference control information includes the TPMI associated with the subset and the number of data stream layers.

Wherein, different said subsets are associated with different PUSCH transmissions, or different said subsets are associated with different sounding reference signal SRS resource indications.

Here, the terminal can look up the table to obtain the TPMI and the number of data stream layers for transmitting the PUSCH according to one or more of the aforementioned subsets indicated.

Specifically, the foregoing terminal antenna coherent characteristic capability information includes: first information (such as fully coherent and partially coherent and non-coherent), and second information (such as partial coherent and non-coherent (Partial And Non-Coherent)). )) or third information (such as non-coherent (Non Coherent)), where the first information includes the first capability (fully Coherent), the second capability (Partial Coherent), and the third capability ( Irrelevant (Non Coherent); the second information includes: the second capability (Partial Coherent) and the third capability (Non Coherent), and the third information includes the third capability (Non Coherent).

The foregoing subset of the first information includes: a combination of any two of the first capability, the second capability, and the third capability, or includes the first capability, the second capability, and the Any one of the third capabilities, which includes: fully And Partial Coherent, fully And Non Coherent, Partial And Non Coherent, fully Coherent, Partial Coherent, or Non Coherent.

A subset of the above second information includes: Partial Coherent or Non Coherent;

A subset of the foregoing third information includes Non Coherent.

In addition, in the embodiment of the present invention, the subset of the terminal antenna coherence characteristic capability information may also include the terminal antenna coherence characteristic capability information itself. When the terminal antenna coherence characteristic capability information is the third information, the subset is not indicated through indication signaling.

In the embodiment of the present invention, the bit information in the DCI simultaneously indicates second reference control information associated with multiple subsets of the terminal antenna coherence characteristic capability information.

By simultaneously indicating the second reference control information associated with multiple subsets of the terminal antenna coherence characteristic capability information through the bit information of the DCI, the signaling overhead of the DCI can be further reduced.

The following describes the above-mentioned first optional implementation manner in conjunction with an embodiment.

Example 1: The network configures {fully And Partial And Non Coherent, partial And Non Coherent, non Coherent, non Coherent) in the codebook Subset of the PUSCH-Config parameter through high-level signaling RRC according to the antenna capabilities reported by the terminal. one of. The configuration in this embodiment is {fully And Partial And Non Coherent}, and the network configures two PUSCH transmissions for the terminal to be associated with different SRIs, and the SRS resource corresponding to each SRI is configured with its own SRS-Spatial RelationInfo (spatial relationship) . Assuming that the terminal is configured with two antenna panels, panel1 and TRP1 maintain the first communication link to transmit PUSCH1, and panel2 and TRP2 maintain the second communication link to transmit PUSCH2.

The first step: The network performs uplink channel measurement according to the SRS pilot periodically sent by the terminal, and after a period of statistical judgment, it is found that the codebook coherent characteristics of the PUSCH transmitted based on the codebook of the two communication links are limited to {fully And Partial And Non Coherent} in the subset. Suppose two cases are considered:

Case 1: The codebook corresponding to PUSCH1 is all in the codebook set corresponding to fully Coherent during the statistical time, and the codebook corresponding to PUSCH2 is all in the codebook set corresponding to non-Coherent during the statistical time.

Case 2: The codebook corresponding to PUSCH1 is in the non-Coherent codebook set during the statistical time, and the codebook corresponding to PUSCH2 is in the fully Coherent codebook set during the statistical time.

Step 2: The network informs the subset information through high-level signaling, where the high-level signaling can be MAC CE. For example, the network specifies the following subset table (Table 1), (the table is only an expression form given as an example, and is not limited to the combinations in the table below).

Table 1

The network indicates two subsets of coherent characteristics to the terminal through MAC CE signaling. For case 1, the configuration index is index=2; for case 2, the configuration index is 6.

The above table 1 can be used to indicate the subsets of the two coherent characteristics at the same time, or the two tables can be used to indicate the subsets of the coherent characteristics respectively. 3 indicates the aforementioned subset 2, and the configuration index=2.

Table 2

index	Coherent subset 1
0	fully
1	partial
2	non

table 3

index	Coherent subset 2
0	fully
1	partial
2	non

Step 3: Assuming that the SRS port associated with the codebook transmission mode of the terminal is configured as 4, the table indicating TPMI information and layer information is shown in Table 4 (this table is just an example of expression, but not limited to the table The order of combination). If the bit information carried in the DCI indicates 6, it indicates that the TPMI of the communication link corresponding to the full coherent is 13, and the TPMI of the communication link corresponding to the non-coherent is 2, regardless of case 1 or case 2.

Table 4

Taking Table 4 as an example, when the maximum number of layers (Max rank) is limited to 1, the DCI only needs to carry 6 bits to indicate precoding information.

The solution of the third step above can also be implemented in the following way: predefining TPMI groups associated with different subsets. The TPMI group is associated with at least one data stream layer number. The information bit in DCI indicates the TPMI used by each subset in the next PUSCH transmission.

Taking the SRS resource antenna port being 4 as an example, TPMI groups associated with different subsets are predefined, and layer=1 is assumed. The specific representation forms are shown in Table 5, Table 6, and Table 7. Among them, Table 5 is the fully Coherent associated TPMI group, the TPMI value in Table 5 includes a natural number between 12 and 27, the TPMI group in Table 5 is associated with 1 layer; Table 6 is the Non Coherent associated TPMI group, and the TPMI in Table 6 The value of includes 0, 1, 2, and 3. The TPMI group in Table 6 is associated with 1layer; Table 7 is the TPMI group associated with Partial Coherent. The value of TPMI in Table 7 includes natural numbers between 4 and 11. The TPMI in Table 7 The group is associated with 1layer.

0	1layer:TPMI=12
1	1layer:TPMI=13

Case 1: When subset 1 is indicated as fully Coherent, and subset 2 is indicated as Non Coherent.

The TPMI is indicated by 6 bits in the DCI, wherein the first 4 bits indicate a TPMI corresponding to the PUSCH or SRI associated with subset 1, and the last 2 bits indicate a TPMI corresponding to the PUSCH or SRI associated with subset 2.

Case 2: When subset 1 is indicated as Non Coherent, and subset 2 is indicated as fully Coherent.

In DCI, 6 bits are used to indicate TPMI, where the first 2 bits indicate a TPMI corresponding to the PUSCH or SRI associated with subset 1, and the last 4 bits indicate a TPMI corresponding to the PUSCH or SRI associated with subset 2.

The number of bits in the DCI can be based on the sum of the number of bits used to indicate the bit information of the TPMI associated with each subset, for example, 4bit+2bit in case 1 above, a total of 6 bits; or pre-defined, for example, determined by high-level signaling.

The first optional implementation manner described above is to jointly indicate the TPMI for transmitting the PUSCH and the number of data stream layers through the indication signaling and the DCI, so as to reduce the signaling overhead of the DCI.

Further, as a second optional implementation manner, the first reference control information includes at least one TPMI subset for transmitting the PUSCH, and each TPMI subset includes a part of the TPMI corresponding to a preset layer, or , Each said TPMI subset includes part of TPMI under multiple different layers at the same time;

The second reference control information includes one TPMI in the TPMI subset, or the second reference control information includes one TPMI and the number of layers in the TPMI subset.

Different TPMI subsets are associated with different PUSCH transmissions, or different TPMI subsets are associated with different SRS resource indications.

In this implementation, the TPMI in the TPMI subset is represented by a bitmap;

Wherein, each bit in the bitmap corresponds to a TPMI, and when the Nth bit of the bitmap is set to the first identifier, it means that the TPMI corresponding to the Nth bit is the TPMI in the TPMI subset, and N is positive. Integer.

For example, there are a total of M1 types of TPMI sets with layer=1 associated with SRI1, and subset 1 indicates N1 types of them (N1<=M1), and M1 bitmaps are used to indicate the TPMIs corresponding to N1 positions. There are a total of M2 types of TPMI sets with layer=1 associated with SRI2, and subset 2 indicates N2 types of them (N2<=M2), and M2 bitmaps are used to indicate the TPMIs corresponding to N2 positions.

Further, the DCI carries K bits, and the K bits are used to jointly indicate the second reference control information used by different PUSCH transmissions, and K is a positive integer.

Among them, the size of K is configured through high-level signaling;

Or, obtained by the formula K=ceil{log ₂ (N1*N2)}, where ceil represents rounding up;

Wherein, the first reference control information includes two TPMI subsets for transmitting the PUSCH, the first TPMI subset of the two TPMI subsets includes N1 TPMI, and the second TPMI subset of the two TPMI subsets includes N2 TPMI. The values of N1 and N2 are notified through signaling, or configured by network equipment, or acquired according to preset parameters.

The preset parameters include at least one of the following:

Different coherence capabilities of terminal antennas;

The number of antenna ports of the SRS resource;

Transmission layer;

The terminal antenna supports the ability to transmit at full power.

That is, the values of N1 and N2 can be determined according to at least one of different coherence capabilities of terminal antennas, the number of antenna ports of SRS resources, transmission layer, and the ability of terminal antennas to support full-power transmission.

In addition, when the indication signaling only indicates a subset (for example, subset 1), K is _{implicitly obtained by the formula K=ceil{log 2} (N1)}.

The second implementation manner described above will be described below in conjunction with the second embodiment.

Embodiment 2: The network performs channel measurement according to the terminal periodically sending SRS pilots, and after a period of time, the network judges the two subsets TPMI_subset1 and TPMI_subset2 of the PUSCH codebook index TPMI transmitted based on the codebook. TPMI_subset1 is used for PUSCH transmission of the first communication link and is associated with TRP1, and TPMI_subset2 is used for PUSCH transmission of the second communication link and is associated with TRP2. Among them, TPMI_subset1 and TPMI_subset2 are notified through high-level signaling, where the high-level signaling can be MAC CE or RRC.

Assume that the antenna port of each PUSCH transmission is 4, and each PUSCH transmission layer is 1.

TPMI_subset1 is indicated by a bitmap with a length of 28, and N1 bits are set to 1 to indicate the selected TPMI subset, where N1(i) represents the i-th TPMI value, and i=0 to N1-1.

Among them, TPMI_subset2 is also indicated by a bitmap with a length of 28, and N2 bits are set to 1 to indicate the selected TPMI subset, where N2(j) represents the jth TPMI value, and j=0~N2-1.

The two subsets TPMI_subset1 and TPMI_subset2 can jointly indicate N1*N2 TPMI combinations, each combination includes two PUSCH corresponding TPMIs, and DCI indicates which combination is specific.

For example, N1=8, N2=8, or N1=4, N2=16, there are a total of 64 combinations. In the DCI, M=6bit is used to indicate the TPMI1 and TPMI2 currently used in the transmission of the two PUSCHs.

Wherein, the number of bearer bits in the DCI can be configured by a higher layer, for example, M=6bit. Either M is configured by a higher layer, or the value of N1 and N2 is implicitly obtained. For example, it is obtained by the formula M=ceil{log ₂ (N1*N2)}, where ceil means rounding up.

Optionally, N1*N2 combinations can be implemented according to a certain rule, assuming N1=8 and N2=8, as shown in Table 8.

Table 8

In this second implementation manner, high-level signaling and DCI are used to jointly indicate the TPMI and the number of data stream layers to reduce the DCI signaling overhead.

Further, acquiring part of the control information for transmitting the physical uplink shared channel PUSCH according to the instruction signaling sent by the network device includes:

According to the instruction signaling sent by the network device, the first part of control information for transmitting the second PUSCH is acquired. The first part of control information is different from the second part of control information, and the second part of control information refers to the transmission of the The second PUSCH transmits control information common to the first PUSCH.

As an optional implementation manner, acquiring part of control information for transmitting the third PUSCH according to a preset rule includes:

In this implementation, the foregoing preset rule may indicate that the transmission of part of the control information of the third PUSCH is determined according to the TPMI for the third PUSCH notified in the latest DCI, or the transmission of part of the control information of the third PUSCH is based on The last used TPMI and SRS resource indication of the third PUSCH are determined, or part of the control information for transmitting the third PUSCH is determined according to the TPMI for the fourth PUSCH notified in the most recent DCI, or the third PUSCH is transmitted Part of the control information is determined according to the preset TPMI value.

Optionally, the partial control information includes: a spatial relationship used for transmitting the third PUSCH;

As another optional implementation manner, the acquiring part of control information for transmitting the third PUSCH according to a preset rule includes:

According to the spatial relationship of the first PUCCH resource dedicated to the UE with the smallest ID in the active uplink bandwidth part BWP of the cell, the spatial relationship used to transmit the third PUSCH is obtained. The first PUCCH resource is from the same source as the third PUSCH. PUCCH resources transmitted by the terminal panel and received from the same TRP;

Or, obtain the spatial relationship used to transmit the third PUSCH according to the spatial relationship of the measured path loss RS, where the RS is the QCL Type-D RS corresponding to the quasi co-located QCL assumption of the first control resource set CORESET, and the first CORESET is the CORESET with the smallest CORESET ID among the CORESETs transmitted from the same terminal panel as the third PUSCH and received from the same TRP;

Or, according to the RS corresponding to the QCL Type-D of the first CORESET, the spatial relationship used for transmitting the third PUSCH is acquired.
