Description

TPMI transmission method, receiving end and transmitting end

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a transmission method of a Transmitted Precoding Matrix Indicator (TPMI), a receiving end, and a transmitting end.

Background

In an uplink transmission mode based on a codebook, a network side device configures an SRS resource set including multiple Sounding Reference Signal (SRS) resources for a terminal, where the number of ports of the multiple SRS resources included in the SRS resource set may be the same or different. In addition, the TPMI corresponding to different SRS resources may be signaled to the terminal by one physical signaling. However, at present, the bit width of the TPMI corresponding to one SRS resource is calculated according to the number of ports of the SRS resource, the number of transmission layers agreed by the base station and the terminal, the maximum number of transmission layers configured for the terminal by a high-level signaling, and a coherent transmission mode of the terminal, and by combining the accumulated number of precoding matrices. However, determining the bit width of the TPMI in this way may cause the bit width of the TPMI corresponding to each SRS resource to be different, and thus the length of the physical signaling received by the receiving end is also different. Therefore, the receiving end needs to perform multiple blind detections according to different physical signaling lengths, and the computational complexity of the receiving end is increased. It can be seen that, in the current communication system, there are problems of many blind detection times of the receiving end and high calculation complexity.

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

The network side device may be a base station, for example: macro station, LTE eNB, 5G NR NB, etc.; the network side device may also be a small station, such as a Low Power Node (LPN), pico, femto, or an Access Point (AP); the base station may also be a network node that is composed of a Central Unit (CU) and a plurality of Transmission Reception Points (TRPs) whose management is and controls. It should be noted that, in the embodiment of the present invention, the specific type of the network-side device is not limited. The receiving end 12 may be a terminal or a network side device. For example: in some scenarios, the transmitting end 11 may be a network side device, and the receiving end 12 may be a terminal, where the scenario is illustrated in the drawings; or in some scenarios, the transmitting end 11 may be a terminal, and the receiving end 12 may be a network side device; or in some scenarios, the transmitting end 11 may be a terminal, and the receiving end 12 may also be a terminal, for example: a Device-to-Device (D2D) communication scenario; or in some scenarios, the sending end 11 may be a network side device, and the receiving end 12 may also be a network side device, for example: communication scenarios between base stations.

Referring to fig. 2, fig. 2 is a flowchart of a TPMI transmission method according to an embodiment of the present invention, as shown in fig. 2, including the following steps:

201. the receiving end selects SRS resources from one or more SRS resource sets;

202. and the receiving end receives a physical signaling, wherein the physical signaling carries the TPMI corresponding to the SRS resource, and under the same transmission mode, bit widths of the TPMI corresponding to each SRS resource in the one or more SRS resource sets are all equal.

The one or more SRS resource sets may be configured by the transmitting end to the receiving end, and the SRS resource set may include one or more SRS resources. For example: the base station configures one or more SRS resource sets including a plurality of SRS resources for the UE, and can enable p_iThe number of ports of the ith SRS resource in one SRS resource set is shown, and M shows the total number of SRS resources in the set.

The SRS resource selection may be performed by the receiving end according to different indication information, for example: different SRS resources can be selected according to different Scheduling Request Indications (SRIs). The selection of the SRS resource may be a selection of one SRS resource, but is not limited thereto.

In addition, step 202 may be to receive the physical signaling in a blind detection manner, for example: and the UE receives the physical layer dynamic signaling sent by the base station in a blind detection mode, wherein the physical layer dynamic signaling comprises the TPMI. Preferably, the physical signaling is Downlink Control Information (DCI), so that the TPMI can be notified through the DCI.

In the embodiment of the invention, because the bit widths of the TPMI corresponding to each SRS resource of the receiving end are equal under the same transmission mode, the blind detection times of the receiving end can be reduced, and the calculation complexity is reduced. Further, in the embodiment of the present invention, in the same transmission mode, the lengths of the physical signaling (e.g., DCI) used for notifying the TPMI corresponding to each SRS resource may be equal, so that the number of blind detections at the receiving end can be further reduced, and the computational complexity can be further reduced.

As an optional implementation, the transmission mode includes: a first transmission mode supporting full Coherent transmission (full Coherent), Partial Coherent transmission (Partial Coherent), and Non-Coherent transmission (Non Coherent), a second transmission mode supporting Partial Coherent and Non-Coherent transmission, or a third transmission mode supporting only Non-Coherent transmission.

The first transmission mode may simultaneously support three transmissions, namely Coherent transmission, partially Coherent transmission And Non-Coherent transmission, And may be denoted as full And Partial And Non-Coherent transmission. While the second transmission mode may be capable of supporting both partially Coherent And Non-Coherent transmissions, And may be denoted as partial And Non-Coherent. Whereas the third transmission mode described above supporting only non-Coherent transmission may represent non Coherent.

In this embodiment, the bit widths of the TPMI corresponding to each SRS resource can be equal in the same transmission mode, so that the blind detection times of the receiving end can be further reduced, and the calculation complexity can be reduced. For example: the SRS resource set configured by the base station for the UE includes two SRS resources, the port numbers of the two SRS resources are 2 And 4, respectively, in the first transmission mode (full And Partial And Non-Coherent), bit widths of TPMIs corresponding to the two SRS resources may be both 6bits (bits), And in the second transmission mode (Partial And Non-Coherent), bit widths of TPMIs corresponding to the two SRS resources may be both 5bits (bits), And in the third transmission mode (Non-Coherent), bit widths of TPMIs corresponding to the two SRS resources may be both 4bits (bits).

As another optional implementation manner, the bit width of the TPMI corresponds to the number of transmission layers supported by the receiving end and a maximum value of the number of ports in the one or more SRS resource sets, where the number of transmission layers is determined according to the maximum value of the number of ports, and the maximum value of the number of ports is the number of ports of the SRS resource with the maximum number of ports in the one or more SRS resource sets.

The number of transmission layers supported by the receiving end may be the maximum number L of transmission layers supported by the receiving end defined in the embodiment of the present invention_maxOr the number of transmission layers supported by the receiving end may be the number of transmission layers L actually supported by the receiving end defined in the embodiment of the present invention. That is, in the embodiment of the present invention, L may be L ═ L_max. The maximum port number may be the port number of the SRS resource with the maximum port number among all SRS resources in the one or more SRS resources.

The bit width of the TPMI corresponds to the number of transmission layers supported by the receiving end and the maximum value of the number of ports in the one or more SRS resource sets, which can be understood as that the transmitting end determines the bit width of the TPMI according to the number of transmission layers supported by the receiving end and the maximum value of the number of ports. For example: and determining the number of preset code matrix code words corresponding to the maximum port number and the maximum transmission layer number supported by the terminal, and determining the bit width required by the number of the code words.

In this embodiment, since the number of ports used for determining the bit width of the TPMI is the maximum value of the number of ports, and the number of transmission layers supported by the receiving end is determined according to the maximum value of the number of ports, it is possible to achieve that the bit widths of the TPMI corresponding to the SRS resources are all equal, thereby reducing the number of blind detections at the receiving end, reducing the computational complexity, and avoiding the excessive signaling overhead caused by the excessive bit width of the TPMI. Of course, in the embodiment of the present invention, it is not limited to implement that the bit widths of the TPMI corresponding to each SRS resource are equal through the number of transmission layers and the maximum number of ports supported by the receiving end, for example: the bit widths of the TPMI corresponding to the SRS resource are configured in advance to be specific bit widths, for example: the bit width of each SRS resource can be satisfied by 6bits, 7 bits, and the like, but the implementation may generate too large signaling overhead.

Optionally, in this embodiment, the number of transmission layers supported by the receiving end may be determined in any manner, that is, the maximum number of transmission layers supported by the receiving end is determinedL_maxOr the number L of transmission layers actually supported by the receiving end.

In the first mode, the number of transmission layers is equal to the maximum number of ports.

In this embodiment, the maximum number of ports may be directly used as the number of transmission layers supported by the receiving end. For example: the number of SRS resource ports that the base station can configure to the UE may be the same or different, and in order to make the TPMI bit width of each SRS resource equal, the number of ports used when calculating the TMPI bit width is the maximum value p of the number of ports in all SRS resources, that is, p is max { p_iI ∈ { 1.,. M } }, max () is a function of taking the maximum value, M is the total number of SRS resources, and the maximum transmission layer number supported by the UE is the maximum value of the port number in all SRS resources, namely L_max＝p。

And in a second mode, the number of transmission layers is the minimum value of the maximum value of the number of ports and the agreed maximum number of transmission layers, wherein the agreed maximum number of transmission layers is the maximum number of transmission layers agreed by the transmitting end and the receiving end.

In this embodiment, the minimum value between the maximum port number and the agreed maximum number of transmission layers may be used as the number of transmission layers supported by the receiving end. For example: on the basis of the first mode, the base station and the UE agree on the maximum number of transmission layers supported by the UE, which is denoted as L_rAt this time, the maximum number of transmission layers supported by the UE is the minimum of the maximum number of ports in all SRS resources and the maximum number of transmission layers supported by the UE agreed by the base station and the UE, i.e., L_max＝min{p,L_rMin () is the minimum function.

And in a third mode, the number of transmission layers is the minimum value of the maximum value of the number of ports and the maximum number of transmission layers reported by the receiving end.

In this embodiment, the minimum value between the maximum port number and the maximum number of transmission layers reported by the receiving end can be used as the number of transmission layers supported by the receiving end. For example: on the basis of the first mode, the UE reports the maximum number of supported transmission layers, denoted as L_UEAt this time, the maximum number of transmission layers supported by the UE is the maximum number of ports in all SRS resources and the maximum number of transmission layers supported by the UE reportMinimum value, i.e. L_max＝min{p,L_UE}。

And in a fourth mode, the number of transmission layers is the minimum value among the maximum port number, the agreed maximum number of transmission layers and the maximum number of transmission layers reported by the receiving end, wherein the agreed maximum number of transmission layers is the maximum number of transmission layers agreed by the transmitting end and the receiving end.

In this embodiment, the minimum value among the maximum value of the number of ports, the agreed maximum number of transmission layers, and the minimum value among the maximum number of transmission layers reported by the receiving end can be used as the number of transmission layers supported by the receiving end. For example: on the basis of the first mode, the UE reports the supported maximum transmission layer number L_UEThe base station and the UE agree on the maximum number L of transmission layers supported by the UE_rAt this time, the maximum number of transmission layers supported by the UE is the minimum of the maximum number of ports in all SRS resources, the maximum number of transmission layers supported by the UE reported by the UE, and the maximum number of transmission layers supported by the UE agreed by the base station and the UE, i.e., L_max＝min{p,L_UE,L_r}。

And in the fifth mode, the transmission layer number is the minimum value of the maximum port number and the maximum transmission layer number configured by the high-level order.

In this embodiment, the minimum value between the maximum port number and the maximum number of transmission layers configured by the higher layer order can be used as the number of transmission layers supported by the receiving end. For example: on the basis of the first mode, the maximum transmission layer number configured for the UE by the higher layer signaling is represented as L_TRIAt this time, the maximum number of transmission layers supported by the UE is the minimum of the maximum number of ports in all SRS resources and the maximum number of transmission layers configured for the UE by the higher layer signaling, that is, L_max＝min{p,L_TRI}。

And a sixth mode, where the number of transmission layers is the minimum value of the maximum port number, the agreed maximum number of transmission layers, and the maximum transmission layer number configured by the higher layer order, where the agreed maximum number of transmission layers is the maximum transmission layer number agreed by the transmitting end and the receiving end.

In this embodiment, the maximum port number, the agreed maximum transmission layer number, and the higher layer order may be allocatedAnd taking the minimum value of the minimum values of the maximum transmission layer numbers as the transmission layer number supported by the receiving end. For example: on the basis of the first mode, the maximum transmission layer number configured for the UE by the higher layer signaling is represented as L_TRIThe base station and the UE agree on the maximum number L of transmission layers supported by the UE_rAt this time, the maximum number of transmission layers supported by the UE is the minimum value of the maximum number of ports in all SRS resources, the maximum number of transmission layers configured for the UE by the higher layer signaling, and the maximum number of transmission layers supported by the UE agreed by the base station and the UE, i.e., L_max＝min{p,L_TRI,L_r}。

And in the seventh mode, the number of transmission layers is the minimum value among the maximum value of the number of ports, the maximum number of transmission layers reported by the receiving end and the maximum number of transmission layers configured by the high-level order.

In this embodiment, the minimum value among the maximum port number, the maximum transmission layer number reported by the receiving end, and the maximum transmission layer number configured by the higher layer order can be used as the transmission layer number supported by the receiving end. For example: on the basis of the first mode, the UE reports the supported maximum transmission layer number L_UEAnd the higher layer signals the maximum transmission layer number L configured for the UE_TRIAt this time, the maximum number of transmission layers supported by the UE is the minimum of the maximum number of ports in all SRS resources, the maximum number of transmission layers supported by the UE and the maximum number of transmission layers configured by the higher layer signaling to the UE, that is, L_max＝min{p,L_UE,L_TRI}。

And in the eighth mode, the number of transmission layers is the minimum value among the maximum number of ports, the maximum number of transmission layers reported by the receiving end, the agreed maximum number of transmission layers, and the maximum number of transmission layers configured by a high-level order, where the agreed maximum number of transmission layers is the maximum number of transmission layers agreed by the transmitting end and the receiving end.

In this embodiment, the minimum value of the maximum number of upper ports, the maximum number of transmission layers reported by the receiving end, the agreed maximum number of transmission layers, and the maximum number of transmission layers configured by the higher layer order may be used as the number of transmission layers supported by the receiving end. For example: on the basis of the mode one, the base station and the UE agree on the maximum number of transmission layers supported by the UEL_rThe maximum number of transmission layers L supported by the UE report_UEAnd the higher layer signals the maximum transmission layer number L configured for the UE_TRIAt this time, the maximum number of transmission layers supported by the UE is the minimum value of the maximum number of ports in all SRS resources, the maximum number of transmission layers supported by reporting by the UE, the maximum number of transmission layers configured by the high-level signaling to the UE, and the maximum number of transmission layers supported by the UE agreed by the base station and the UE, that is, L_max＝min{p,L_UE,L_TRI,L_r}。

Optionally, in an embodiment, the bit width of the TPMI is equal to a result calculated by the following formula:

is rounded up.

That is, the transmitting end may calculate the bit width of the TPMI through the above formula.

The specific calculations can be shown in table 1:

table 1:

in this embodiment, the cumulative number of precoding matrix codewords and the corresponding bit width of the TPMI can be calculated by the above formula.

In addition, the number of ports is p, and the number of precoding matrix codewords corresponding to the number of transmission layers is k may be obtained by table lookup, or the transmitting end (e.g., base station) is configured with the corresponding number of codewords in advance.

And indicating the number of precoding matrix codewords corresponding to the number of ports p and the number of transmission layers k in the transmission mode supported by the receiving end.

The transmission mode supported by the receiving end may be a first transmission mode (full And Partial And Non-Coherent), a second transmission mode (Partial And Non-Coherent), or a third transmission mode (Non-Coherent).

For example: the number of precoding matrix codewords corresponding to different transmission layer numbers, such as the port number of 2 in table 3, and the number of precoding matrix codewords corresponding to different transmission layer numbers, such as the port number of 4 in table 4:

table 3: number of precoding matrix code words corresponding to different transmission layer numbers with port number of 2

	Full And Partial And Non Coherent	Non Coherent
			1 layer of	6	2
2 layers of	3	1

Table 4: number of precoding matrix code words corresponding to different transmission layer numbers with port number of 4

As can be seen from Table 3, when p is 2, the transmission mode is Full And Partial And Non Coherent, And k is 1,

Optionally, the

The transmission mode supported by the receiving end may also be a first transmission mode (full And Partial And Non-Coherent), a second transmission mode (Partial And Non-Coherent), or a third transmission mode (Non-Coherent).

And indicating the number of precoding matrix codewords corresponding to the port number p with the number of transmission layers being L in the transmission mode supported by the receiving end, so that the number of codewords in each transmission mode can be accurately calculated, and the bit width of the TMPI corresponding to each SRS resource in the same transmission mode is ensured to be equal.

wherein the first transmission mode supports full And Partial Coherent transmission And Non-Coherent transmission (Non Coherent), And the third transmission mode supports Non-Coherent transmission only.

In this embodiment, if one or more SRS resource sets include SRS resources of two ports, And a high-level signaling is configured to the receiving end to support partial Coherent transmission And support incoherent transmission (partial And Non-Coherent), the receiving end determines the bit width of the TPMI according to the first transmission mode or the third transmission mode, so as to avoid the problem that the bit width of the TPMI is not equal due to the fact that the SRS resources of the two ports do not support partial Coherent transmission And support incoherent transmission (partial And Non-Coherent).

For example: the SRS resource set configured by the base station for the UE comprises the SRS resources of 2 ports, and the high-level signaling is configured for the UE to support both partial coherent transmission and non-coherent transmission. Since the 2-port SRS resource does not support the transmission method, the TPMI bit width is calculated according to the following two transmission methods supported by the UE.

For example: supporting various Coherent transmission modes (full And Partial And Non Coherent) according to UE

And calculating the TMPI bit width in a corresponding mode.

Another example is: supporting various Coherent transmission modes (full And Partial And Non Coherent) according to UE

And calculating the TMPI bit width in a corresponding mode.

Another example is: according to the non-Coherent transmission mode (non Coherent) supported by UE

And calculating the TMPI bit width in a corresponding mode.

And calculating the TMPI bit width in a corresponding mode.

It should be noted that, in the embodiment of the present invention, determining the bit width of the TMPI is not limited to be determined by the above two formulas, for example: it can also be determined by the following tables 5 to 8, wherein tables 5 to 8 are specifically as follows:
