Description

TECHNICAL FIELD

[0001] The present application relates to the field of wireless communication, and particularly relates to an information indication method and device, related equipment and a storage medium. BACKGROUND

[0002] In order to improve the reliability of a physical uplink shared channel (PUSCH) in a multi-transmission and reception point (Multi-TRP) scenario, PUSCH repetition transmission can be introduced. On the other hand, one way of working of the Multi-TRP scenario is that only one transmission and reception point (TRP) transmits a physical downlink control channel (PDCCH) for scheduling a terminal to transmit a physical uplink shared channel (PUSCH). In this way of working, considering that the channels of multiple TRPs are completely different, the power of the PUSCH determined based on the channels of multiple TRPs is also different, and therefore, how to indicate the closed-loop power control commands of multiple PUSCHs is a problem to be solved at present.

[0071] The application will be further described below in conjunction with the accompanying drawings and embodiments.

[0072] The general formula for calculating the uplink transmission power P is as follows:

[0073]

[0074] The closed loop part f(i) is the power control adjustment state at the i-th moment, which can quickly adjust the power of a transmission of a certain terminal. The adjustment is based on the effect of the last transmission, and the adjustment information is referred to as TPC Command, which is adjusted quickly through DCI, represented as δ(i). If the radio resource control (RRC) parameter tpc-Accumulation is in a non-enabled state, the absolute value closed loop power control is enabled, and at this time f(i) = δ(i). If the RRC parameter tpc-Accumulation is in an enabled state, the cumulative closed loop power control is enabled, and at this time f(i) = f(i-1) + δ(i). Here, the TPC Command field mapping table is as follows:

[0075] ■TPC Command Field Accumulated δ PUSCHb，f，c or δ SRS，b，f，c [dB]]]> Absolute δ PUSCH,b，f，c or δ SRS，b，f，c [dB]]]> ■0 -1 -4 ■1 0 -1 ■2 1 1 ■3 3 4

[0076] Table 1

[0077] On the other hand, the transmission mode of PUSCH can include a codebook-based transmission mode and a non-codebook-based transmission mode. Specifically,

[0078] When the PUSCH is configured as a codebook-based transmission mode, as Figure 1As shown, first, the terminal needs to send a channel sounding reference signal (SRS) for codebook-based uplink transmission, i.e., the usage parameter in the SRS set is configured as codebook. Among them, for the codebook-based uplink transmission scheme, in the new radio (NR) system, the base station is allowed to configure at most one SRS set for the terminal for uplink channel estimation, and the SRS set can be configured with at most two SRS resources. Next, the base station performs uplink channel detection according to the SRS sent by the terminal, determines the SRS resource indication (SRI) corresponding to the uplink transmission, the number of uplink transmission layers (RI), the transmission precoding matrix indication (TPMI), the modulation and coding strategy (MCS), etc., and notifies the terminal of these information in the DCI. Then, the terminal determines the precoding information of the PUSCH according to the indicated RI, TPMI, MCS, etc., and determines the beam direction of the PUSCH to be consistent with the beam direction of the SRS according to the indicated SRI, and the SRS corresponding to the SRI is the SRS sent most recently before the DCI scheduling the PUSCH.

[0079] Here, by way of example, Table 2 shows the SRI indication based on codebook transmission.

[0080]

[0081] Table 2

[0082] When the PUSCH is configured as a non-codebook-based transmission mode, as shown in Figure 2 , first, the terminal needs to send an SRS for non-codebook-based uplink transmission, i.e., the usage in the SRS set is configured as non-codebook. For the non-codebook uplink transmission scheme, the base station can configure at most one SRS set for the terminal, containing 1-4 SRS resources, each SRS resource is a single port, the terminal determines the precoding of the SRS based on the downlink channel estimation, and sends the precoded SRS. The base station performs uplink channel detection according to the SRS sent by the terminal, determines the SRI corresponding to the uplink transmission, the MCS, etc., and indicates the SRI in the DCI, wherein the SRI can indicate one or more SRS resources. The number of SRS resources indicated in the SRI is the RI of the PUSCH transmission, and the precoding adopted by the SRS resource indicated in the SRI is the TPMI of the PUSCH transmission, and the transmission layer of the PUSCH corresponds one-to-one to the SRS resource indicated by the SRI. Here, by way of example, Table 3 shows the SRI indication based on non-codebook transmission.

[0083]

[0084] Table 3

[0085] From the above description, it can be seen that the main difference between the non-codebook-based uplink transmission scheme and the codebook-based uplink transmission scheme is that the corresponding precoding is no longer limited to the limited candidate set based on the fixed codebook. And the terminal can determine the precoding and the number of transmission layers of data by using the SRI.

[0086] In the related art, as shown in Figure 3 In a Multi-TRP communication scenario, one way of working is to transmit PDCCH by only 1 TRP to schedule the terminal to transmit PUSCH, that is, the terminal needs to be instructed by 1 DCI to indicate the transmission power control command (TPC command) value of the PUSCH from 2 TRPs respectively. However, since the channels of the 2 TRPs are completely different, the power of the PUSCH determined based on the channels of the 2 TRPs is also different, and how to instruct the terminal by 1 DCI to indicate the TPC command value from multiple PUSCHs is a problem to be solved at present.

[0087] Based on this, in various embodiments of the present application, the network side transmits a DCI carrying one TPC command to the terminal, so as to instruct the terminal to determine the TPC command value of each PUSCH in multiple PUSCHs by using the one TPC command, that is, within the DCI format framework of the related art, the closed-loop power control indication of the PUSCH of multiple TRPs can be indicated without increasing the DCI payload.

[0088] The embodiment of the present application provides an information indication method, applied to a terminal, as shown in Figure 4 The method comprises the steps of:

[0089] Step 401: receiving a first DCI transmitted by the network side, wherein the first DCI carries a first TPC command;

[0090] Step 402: determining the TPC command value of each PUSCH in at least two PUSCHs by using the first TPC command.

[0091] In actual application, the terminal can also be referred to as a user equipment (UE), and can also be referred to as a user, etc.

[0092] The DCI is carried in the PDCCH.

[0093] The first TPC command is set in the TPC command field of the first DCI.

[0094] To improve the reliability of PUSCH transmission in the Multi-TRP scenario, when PUSCH repetition transmission is used, the data carried by the at least two PUSCHs is the same. Of course, the data carried by part of the at least two PUSCHs can also be the same.

[0095] In actual application, the data carried by the at least two PUSCHs can also be different, such as carrying part of the data, and the network side can combine the data carried by the at least two PUSCHs to obtain complete data.

[0096] Here, in the related art, the TPC Command field in the DCI has only 2 bits, so there is no effective solution for how to flexibly and effectively indicate the closed-loop power control command of multiple PUSCHs on the limited bits.

[0097] Based on this, the embodiments of the present application provide the following implementation manners:

[0098] The first way is that the TPC commands received by multiple PUSCHs remain consistent, that is, the δ(i) indicated by the TPC Command Field simultaneously acts on multiple PUSCHs, that is, the TPC command value applied to each PUSCH is the same, and only the DCI can indicate the TPC command value of multiple PUSCHs, and the implementation is relatively simple.

[0099] Exemplarily, assuming that there are 2 PUSCHs, taking the cumulative closed-loop power as an example, in combination with the related art, the cumulative δ(i) of each PUSCH has four candidate values of {-1, 0, 1, 3}, so that the 2 bits in the TPC Command Field can indicate 4 δ(i), and simultaneously act on the 2 PUSCHs, and the TPC Command mapping table can be as shown in Table 4, which is not limited by the embodiments of the present application.

[0100] TPC Command Field Accumulated δ(i) 0 -1 1 0 2 1 3 3

[0101] Table 4

[0102] The second way is that each bit in the TPC Command Field independently indicates the δ(i) of multiple PUSCHs, that is, each bit of the first TPC command indicates the TPC command value of one of the at least two PUSCHs, so that flexible indication of the TPC command value can be realized.

[0103] Here, in actual application, in order to realize that each bit in the TPC Command Field respectively and independently indicates the δ(i) of multiple PUSCHs, the terminal needs to know the candidate δ(i) in advance.

[0104] Among them, the network side can configure the candidate TPC Command value for the terminal.

[0105] Based on this, in an embodiment, the method can further include:

[0106] receiving first information; the first information indicates at least two candidate TPC command values;

[0107] determining the TPC command value of each of the at least two PUSCHs by using the first information and the first TPC command.

[0108] Here, in actual application, the candidate TPC Command value can be configured by RRC, or activated by MAC CE, or indicated by DCI.

[0109] Based on this, in an embodiment, the first information is received by one of the following ways:

[0110] RRC signaling;

[0111] MAC CE;

[0112] DCI.

[0113] In actual application, if the network side does not dynamically select the candidate TPC Command value, the terminal can set multiple default TPC Command values.

[0114] Exemplarily, assuming there are 2 PUSCHs, taking cumulative closed loop power control as an example, according to the related art, there are four candidate values {-1, 0, 1, 3} for cumulative δ(i) of each PUSCH, two candidate TPC Command values selected by the terminal are referred to as a first TPC Command value (abbreviated as 1thδ(i)) and a second TPC Command value (abbreviated as 2thδ(i)), and 2 bits in the TPC Command Field independently indicate δ(i) of the two PUSCHs, codepoint = 0 represents the first selected δ(i), codepoint = 1 represents the second selected δ(i), and Table 5 shows the mapping relationship of TPC Command of a certain PUSCH, 1thδ(i) represents that the TPC Command value received by the PUSCH is the first selected δ(i), and 2thδ(i) represents that the TPC Command value received by the PUSCH is the second selected δ(i).

[0115] TPC Command Field Accumulated δ(i) 0 1th δ(i) 1 2th δ(i)

[0116] Table 5

[0117] The third mode is that multiple bits in the TPC Command Field jointly indicate δ(i) of multiple PUSCHs, that is, at least two bits of the first TPC command jointly indicate the TPC command value of each PUSCH in the at least two PUSCHs, so that flexible indication of the TPC command value can be realized, and the joint indication mode can indicate the TPC command values of multiple PUSCHs on the basis of saving bits.

[0118] Here, in actual application, in order to realize that multiple bits in the TPC Command Field jointly indicate δ(i) of multiple PUSCHs, the terminal needs to know candidate δ(i) in advance.

[0119] Among them, the network side can configure candidate TPC Command values for the terminal.

[0120] Based on this, in an embodiment, the method can further include:

[0121] receiving first information; the first information indicates at least two candidate TPC command values;

[0122] determining the TPC command value of each PUSCH in the at least two PUSCHs by using the first information and the first TPC command.

[0123] Here, in actual application, the candidate TPC Command value can be configured by RRC, activated by MAC CE, or indicated by DCI.

[0124] Based on this, in an embodiment, the first information is received by one of the following manners:

[0125] RRC signaling;

[0126] MAC CE;

[0127] DCI.

[0128] In actual application, if the network side does not dynamically select the candidate TPC Command value, the terminal can set multiple default TPC Command values.

[0129] For example, assuming that there are two PUSCHs, taking the cumulative closed-loop power as an example, according to the related art, each PUSCH has four candidate values of cumulative δ(i), i.e., {-1, 0, 1, 3}, and the terminal selects two candidate TPC Command values, referred to as a first TPC Command value (abbreviated as 1thδ(i)) and a second TPC Command value (abbreviated as 2thδ(i)), and two bits in the TPC Command Field jointly indicate the δ(i) of the two PUSCHs, codepoint=0 indicates a group of δ(i), codepoint=1 indicates a second group of δ(i), and so on, and Table 6 shows a certain TPC mapping relationship of the two PUSCHs.

[0130]

[0131]

[0132] Table 6

[0133] It should be noted that the scheme of absolute value closed-loop power control can be understood with reference to the cumulative closed-loop power control, which will not be described here.

[0134] From the above description, it can be seen that the above three manners, the TPC closed-loop power control adjustment scheme in the DCI format framework of the related art, indicates the closed-loop power control indication of the PUSCHs of multiple TRPs while maintaining a certain power control flexibility without increasing the DCI payload.

[0135] The second manner and the third manner both directly indicate the δ(i) of the multiple PUSCHs to the terminal through the TPC Command Field in the DCI.

[0136] After determining the TPC command value of each of the at least two PUSCHs, the terminal can determine the transmission power of each PUSCH according to the TPC command value of each PUSCH. Specifically, the transmission power of each PUSCH (also referred to as transmission power) can be determined according to the general calculation formula of the transmission power P described above.

[0137] In actual application, in a Multi-TRP communication scenario, the terminal can be dynamically instructed to use Multi-TRP PUSCH transmission or Single-TRP (Single-TRP) PUSCH transmission.

[0138] Based on this, in an embodiment, the method can further include:

[0139] receiving second information sent by the network side, the second information indicating whether the at least two PUSCHs are all scheduled.

[0140] Here, in actual application, the network device can determine to use Multi-TRP PUSCH transmission (i.e. transmission of at least two PUSCHs) or Single-TRP PUSCH transmission according to needs, and then can dynamically instruct the terminal to use Multi-TRP PUSCH transmission or Single-TRP PUSCH transmission through DCI.

[0141] Based on this, in an embodiment, the receiving of the second information sent by the network side includes:

[0142] receiving second DCI sent by the network side, the second DCI carrying the second information.

[0143] In actual application, the first TPC command can be carried in one DCI with the second information, in which case the second DCI is the same as the first DCI; of course, the first TPC command can also not be carried in one DCI with the second information, in which case the second DCI is different from the first DCI.

[0144] Exemplarily, the second information can be set in the SRI field or the TPMI field of the DCI, and specifically can be set in the reserved bit of the SRI field or the TPMI field of the DCI, such as when set as 0 or null, indicating that the terminal uses Single-TRP PUSCH transmission, otherwise, indicating that the terminal uses Multi-TRP PUSCH transmission.

[0145] In actual application, when the terminal is instructed to use Single-TRP PUSCH transmission, the TPC Command mapping relationship table in the related art can be used, that is, the TPC Command mapping relationship shown in Table 1 can be used.

[0146] To reduce the processing complexity of the terminal, specifically the complexity of power adjustment processing, for Multi-TRP transmission and Single-TRP transmission, the TPC command value indicated to one TRP in the DCI in the Multi-TRP case should belong to the same power control closed loop (expressed in English as powerControlLoop) as the TPC command value of the TRP in the Single-TRP case.

[0147] Based on this, in an embodiment, for the first PUSCH of the at least two PUSCHs, if the power control adjustment state indexes corresponding to the TPC commands in the first condition and the second condition are the same, the power control closed loop to which the TPC commands in the first condition and the second condition are applied is the same; the first condition represents that the at least two PUSCHs are both scheduled; and the second condition represents that only the first PUSCH of the at least two PUSCHs is scheduled.

[0148] Correspondingly, the embodiment of the present application also provides an information indication method, applied to a network device (specifically, a base station), comprising:

[0149] sending a first DCI to the terminal, the first DCI carrying a first TPC command; the first TPC command is used to determine the TPC command value of each PUSCH of the at least two PUSCHs.

[0150] In an embodiment, the method can further comprise:

[0151] sending first information to the terminal, the first information indicating at least two candidate TPC command values.

[0152] Here, in an embodiment, the first information is sent to the terminal by one of the following methods:

[0153] RRC signaling;

[0154] MAC CE;

[0155] DCI.

[0156] In an embodiment, the method can further include:

[0157] sending second information to the terminal, the second information indicating whether the at least two PUSCHs are both scheduled.

[0158] In an embodiment, the sending second information to the terminal includes:

[0159] sending second DCI to the terminal, the second DCI carrying the second information.

[0160] Embodiments of the present application also provide an information indication method, as shown in Figure 5 The method includes the following steps:

[0161] Step 501: a network device sends first DCI to a terminal, the first DCI carrying a first TPC command; the first TPC command is used to determine a TPC command value of each PUSCH in at least two PUSCHs.

[0162] Step 502: after receiving the first DCI, the terminal determines a TPC command value of each PUSCH in at least two PUSCHs by using the first TPC command.

[0163] The information indication method provided by the embodiments of the present application includes that a network device sends first DCI to a terminal, the first DCI carrying a first TPC command; the first TPC is used to determine a TPC command value of each PUSCH in at least two PUSCHs; and the terminal determines a TPC command value of each PUSCH in at least two PUSCHs by using the first TPC command. The scheme provided by the embodiments of the present application includes that the network side sends DCI carrying one TPC command to the terminal, so as to instruct the terminal to determine a TPC command value of each PUSCH in multiple PUSCHs by using the one TPC command. Thus, the closed-loop power control indication of the PUSCHs of multiple TRPs is realized without increasing the DCI payload.
