Abstract
Description
Technical Field
[0001] This application belongs to the field of communication technology, specifically relating to a PUSCH transmission method, apparatus, device, and storage medium. Background Technology

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0048] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used not only in the systems and radio technologies mentioned above, but also in other systems and radio technologies. The following description describes New Radio (NR) systems for illustrative purposes, and NR terminology is used in most of the following description; however, these technologies can also be applied to applications beyond NR systems, such as 6th Generation (6G) communication systems.
[0049] Figure 1This is a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can also be referred to as a terminal device or user equipment (UE). The terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), etc. Wearable devices include wristbands, headphones, glasses, etc. It should be noted that the specific type of terminal 11 is not limited in this application embodiment.

The base station can be referred to as a node B, evolved node B, access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, WiFi node, transmitting and receiving point (TRP), or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that in this embodiment of the application, only the base station in the NR system is used as an example, but the specific type of base station is not limited.
[0050] In multi-TRP / multi-panel scenarios within a communication system, transmission reliability and throughput performance can be increased. In the downlink, the UE can receive the same or different data from multiple TRPs. In the uplink, the UE can send different data to multiple TRPs. The network side can configure multiple CORESETs for the UE, associated with different RRC parameters (CORESETPoolIndex), each corresponding to a different TRP. Each TRP schedules its own uplink transmission PUSCH by sending its own DCI; that is, in a multi-TRP scenario, multi-DCI scheduling of PUSCH transmission is used. The communication system further enhances the PUSCH under MTRP, allowing the UE to send the same data to two TRPs.
[0051] In MTRP scenarios, a single transport block (TB) of a PUSCH can be repeatedly transmitted to multiple TRPs. Each repeated PUSCH transmission employs multiple sets of parameters tailored to different TRPs, including spatial relationships, precoding matrices, and power control. Current technology supports a maximum of two sets of spatial relationships for repeated PUSCH transmissions, requiring two sets of parameters for the corresponding TPMI. In MTRP scenarios, a maximum of two SRS resource sets can be configured for codebook or non-codebook transmissions. The SRI and TPMI fields of the corresponding DCI for scheduling the PUSCH need to be doubled in bit count to indicate the two sets of parameters.
[0052] In uplink full-power transmission, each SRS resource set can be configured with up to four SRS resources, and multiple TPMIs can also be introduced to indicate the full-power transmission codebook. However, the bit overhead of the SRI and TPMI fields is already significant. If the existing scheme is continued, directly doubling the SRI and TPMI fields would result in extremely high DCI overhead. Furthermore, MTRP scenarios may support repeated PUSCH transmissions targeting more TRPs, in which case the existing scheme is no longer applicable.
[0053] To overcome the above-mentioned defects, this application proposes a PUSCH transmission method and apparatus.
[0054] The PUSCH transmission method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0055] Figure 2 This is one of the flowcharts illustrating the PUSCH transmission method provided in the embodiments of this application, such as... Figure 2 As shown, the method includes the following steps:
[0056] Step 200: Based on the received first indication information, the terminal determines the target transmission resource configuration indicated by the first indication information from at least one transmission resource configuration;
[0057] Step 210: Based on the target transmission resource configuration, transmit the PUSCH;
[0058] The first indication information includes at least one of the following:
[0059] Detection reference signal (SRS) resource indication information;
[0060] Precoding matrix indicates TPMI indication information;
[0061] Phase Tracking Reference Signal (PTRS) transmission port indication information;
[0062] The configuration of at least one transmission resource is determined based on at least one of the following:
[0063] Prior instructions from the network side;
[0064] Protocol predefined;
[0065] Pre-configured;
[0066] RRC layer indication;
[0067] MAC layer indication.
[0068] Optionally, the target transmission resource configuration can be the resource configuration used by the terminal to transmit PUSCH.
[0069] Optionally, for codebook-based PUSCH transmission, the network side can configure an SRS resource set for the UE to obtain based on uplink transmission CSI. Each SRS resource set can contain two SRS resources. The two SRS resources can contain the same number of ports, i.e., both can be ports 1, 2, and 4. These two SRS resources can be configured to correspond to different beams.
[0070] The network side can obtain uplink channel information by measuring SRS on different SRS resources, and select parameters such as spatial relationship, precoding matrix, power control, and MCS for PUSCH transmission for the UE based on this uplink channel information. These transmission parameters are indicated to the UE through the SRI / TPMI / TPC / MCS fields in the DCI format0_1 / 0_2 of the PUSCH scheduling. During PUSCH transmission, the same spatial relationship and port as the SRS resources indicated by the SRI field can be used.
[0071] Optionally, for non-codebook transmission, each SRS resource set used for non-codebook transmission can be configured with 4 SRS resources, and all SRS resources can have 1 port. Each SRS resource set can be configured with associated CSI-RS for the UE to measure the downlink channel. Based on channel reciprocity, the UE can assume the measured downlink channel as the uplink channel and calculate the uplink transmission precoding matrix based on this channel information. The UE can then use this precoding matrix to precode the SRS and send it to the network side. The network side can determine the precoding used by the UE for PUSCH transmission based on the measured precoded SRS and indicate this through the SRI field of the DCI for scheduling PUSCH. That is, the SRI field can indicate the subset of all precoded SRS resources sent by the UE, thus indicating the precoding matrix used for PUSCH transmission.
[0072] Optionally, SRS resource indication information can be used to indicate SRS resources, and the terminal can use the same spatial relationship and port to transmit PUSCH as the SRS resource.
[0073] Optionally, the precoding matrix can be indicated using TPMI indication information, and the terminal can use the precoding matrix to precode the SRS.
[0074] Optionally, PTRS transmission port indication information can be used to indicate the PTRS transmission port, and the PTRS-DMRS association field can indicate which layer the PTRS is uploaded to; the terminal can determine which layer the PTRS is uploaded to.
[0075] Optionally, one layer can correspond to one DM-RS port.
[0076] Optionally, the corresponding information in the resource configuration for transmitting PUSCH can be indicated by any one or any combination of TPMI indication information, PTRS transmission port indication information, and TPMI indication information.
[0077] Optionally, after determining the target transmission resource configuration, that is, after determining the resource configuration used for transmitting PUSCH, PUSCH can be transmitted based on the resource configuration used for transmitting PUSCH.
[0078] Optionally, the terminal may determine the target transmission resource configuration indicated by the first indication information based on the first indication information in the DCI;
[0079] The first indication information is used to indicate the target transmission resource configuration in at least one transmission resource configuration.
[0080] Optionally, the network side can include the first indication information in the DCI and send it to the terminal. After receiving the DCI, the terminal can obtain the first indication information and determine the target transmission resource configuration indicated by the first indication information.
[0081] It is understandable that the first instruction information only includes the instruction content. The specific transmission resource configuration content can be sent to the terminal separately by the network side, or it can be predefined or preconfigured by the protocol, or indicated by the RRC layer, or indicated by the MAC layer.
[0082] Optionally, in the MTRP scenario, PUSCH transmission can use at least one set of spatial relationships and at least one set of TPMI.
[0083] Optionally, multiple sets of spatial relationships and multiple sets of TPMI parameters can be proposed, that is, one or more transmission resource configurations can be proposed; optionally, corresponding resource indication can also be performed through various indication methods; it can support PUSCH-oriented multi-TRP transmission while ensuring low DCI overhead for scheduling PUSCH repetitive transmission.
[0084] Optionally, when the terminal determines the target transmission resource configuration indicated by the first indication information, it can determine the target transmission resource configuration indicated by the first indication information from one or more transmission resource configurations based on the first indication information.
[0085] The embodiments of this application indicate at least one transmission resource configuration, i.e., multiple sets of transmission parameters, for repeated transmission of UE PUSCH, while ensuring that no additional DCI overhead is added.
[0086] In this embodiment, at least one of SRS resource indication information, TPMI indication information, and PTRS transmission port indication information is used to indicate the target transmission resource configuration for PUSCH transmission to the terminal, thereby reducing the bit overhead of the SRI field and / or TPMI field when configuring PUSCH transmission resources.
[0087] Optionally, the SRS resource indication information includes SRI domain code point values;
[0088] The terminal determines the target transmission resource configuration indicated by the first indication information based on the first indication information in the DCI, including:
[0089] Based on the SRI field code point value in the DCI, at least one target SRI field code point information is determined from the SRI field code point information; the at least one SRI field code point information is determined by the terminal based on at least one of the following:
[0090] Prior instructions from the network side;
[0091] Protocol predefined;
[0092] Pre-configured;
[0093] RRC layer indication;
[0094] MAC layer indication;
[0095] Among them, the SRI domain code point information is associated with at least one SRS resource, or the SRI domain code point information is associated with at least one SRS resource group.
[0096] Optionally, the SRS resource indication information includes the SRI field code point value, which can be a low-bit value.
[0097] Optionally, at least one transmission resource configuration may include at least one SRI domain code point information;
[0098] Optionally, the SRI domain code point information is associated with at least one SRS resource.
[0099] Optionally, the SRI domain code point information is associated with at least one SRS resource group;
[0100] Optionally, the terminal can determine, based on the SRI domain code point value, the target SRI domain code point information indicated by the SRI domain code point value in at least one SRI domain code point information, and then obtain the SRS resource or SRS resource group associated with the target SRI domain code point information.
[0101] Optionally, the different SRI domain code point values correspond one-to-one with the at least one SRI domain code point information; the correspondence between the different SRI domain code point values and the at least one SRI domain code point information is pre-indicated by the network side, or pre-defined or pre-configured by the protocol, or indicated by a second signaling, wherein the second signaling is RRC layer signaling or MAC layer signaling.
[0102] Optionally, different SRI field code point values can correspond one-to-one with at least one SRI field code point information. Then, the terminal can determine the target SRI field code point information that corresponds one-to-one with the SRI field code point value in at least one SRI field code point information based on the SRI field code point value.
[0103] Optionally, the correspondence between different SRI domain code point values and the at least one SRI domain code point information may be pre-indicated by the network side, or pre-defined or pre-configured by the protocol, or indicated by a second signaling, wherein the second signaling is RRC layer signaling or MAC layer signaling.
[0104] Optionally, the correspondence between different SRI field code point values and the at least one SRI field code point information can be described by a table.
[0105] For example, as shown in Table 1 below, the network side configures two SRS resource sets for the UE for non-codebook transmission. Each resource set contains four SRS resources (indexed as 0, 1, 2, 3). The UE receives network-side higher-layer signaling MACCE, which includes four code points. The SRI field of the DCI is 2 bits, corresponding to the four code points.
[0106] Table 1 SRI Domain Code Point Information Indicator Table
[0107]
[0108] Based on Table 1, when the SRI field code point value of the DCI that schedules repeated PUSCH transmissions is 0, it means that the repeated PUSCH transmission corresponds to a set of spatial relationships, and that all repeated PUSCH transmissions use the same spatial relationship as the first SRS resource of the first SRS resource set.
[0109] When the SRI field code point value of the DCI scheduling a PUSCH retransmission is 1, it indicates that the PUSCH retransmission corresponds to two sets of spatial relationships. The first spatial relationship is the same as the first SRS resource of the first SRS resource set, and the second spatial relationship is the same as the first SRS resource of the second SRS resource set. The first and second retransmissions of the PUSCH retransmission use the first spatial relationship, and the third and fourth retransmissions use the second spatial relationship.
[0110] When the SRI field code point value of the DCI scheduling a PUSCH retransmission is 2, it indicates that the PUSCH retransmission corresponds to two sets of spatial relationships. The first spatial relationship is the same as the second SRS resource of the first SRS resource set, and the second spatial relationship is the same as the first SRS resource of the second SRS resource set. The first and second retransmissions of the PUSCH retransmission use the first spatial relationship, while the third and fourth retransmissions use the second spatial relationship.
[0111] When the SRI field code point value of the DCI that schedules repeated PUSCH transmissions is 3, it indicates that the repeated PUSCH transmission corresponds to a set of spatial relationships, meaning that all repeated PUSCH transmissions use the same spatial relationship as the second SRSresource in the second SRS resource set.
[0112] For example, as shown in Table 1 below, the network side configures two SRS resource sets for the UE for codebook transmission. Each resource set contains two SRS resources. The UE receives the network side's higher-layer signaling MAC CE, which includes four SRI field code point information. Among them, the SRI field of DCI is 2 bits, which can be 00, 01, 10, or 11, corresponding to the four SRI field code point values.
[0113] Table 1 SRI Domain Code Point Information Indicator Table
[0114]
[0115] For example, as shown in Table 2 below, the network side configures two SRS resource sets for the UE for non-codebook transmission. Each resource set contains four SRS resources (indexed as 0, 1, 2, 3). The UE receives the network side's higher-layer signaling MACCE, which includes four SRI field code point information. The SRI field of the DCI is 2 bits, which can be 00, 01, 10, or 11, corresponding to the four SRI field code point values.
[0116] Table 2 SRI Domain Code Point Information Indication Table
[0117]
[0118] Based on Table 2, when the SRI field code point value of the DCI scheduling repeated PUSCH transmissions is 0, it indicates that the repeated PUSCH transmission corresponds to two SRS resource groups, and the PUSCH transmission timing is associated with each of the two SRS resource groups. The port corresponding to the PUSCH transmission timing associated with the first SRS resource group is the same as the SRS resource(s) with indices 0, 1, and 2 in the first SRS resource set. The port corresponding to the PUSCH transmission timing associated with the second SRS resource group is the same as the SRS resource(s) with indices 1, 2, and 3 in the first SRS resource set.
[0119] When the SRI field code point value of the DCI scheduling a PUSCH retransmission is 1, it indicates that the PUSCH retransmission corresponds to two SRS resource groups, and the PUSCH transmission timing is associated with each of the two SRS resource groups. The port corresponding to the PUSCH transmission timing associated with the first SRS resource group is the same as the SRS resource(s) with indices 1 and 2 in the first SRS resource set. The port corresponding to the PUSCH transmission timing associated with the second SRS resource group is the same as the SRS resource(s) with indices 2 and 3 in the first SRS resource set.
[0120] When the SRI field code point value of the DCI that schedules repeated PUSCH transmissions is 2, it indicates that the repeated PUSCH transmission is associated with an SRS resource group, and the port corresponding to all PUSCH transmission times is the same as the SRS resource(s) with index 0, 1, 2, 3 in the first SRS resource set.
[0121] When the SRI field code point value of the DCI that schedules repeated PUSCH transmissions is 3, it indicates that the repeated PUSCH transmission is associated with an SRS resource group, and the port corresponding to all PUSCH transmission times is the same as the SRS resource(s) with index 0, 1, 2, 3 in the second SRS resource set.
[0122] For example, as shown in Table 3 below, the network side configures two SRS resource sets for codebook transmission for the UE, with two SRS resources configured in each set. The UE can receive MAC CE. The MAC CE activates one SRS resource in each set, that is, the number of bits of SRI is 0, so there is no need to indicate the SRI code point information; the SRI field of DCI indicates the SRI field code point value through 2 bits.
[0123] Table 3 SRI Domain Code Point Information Indication Table
[0124]
[0125]
[0126] For example, as shown in Table 4 below, the network side configures two SRS resource sets for the UE for codebook transmission, with four SRS resources configured in each set. The UE receives a MAC CE, which activates the two SRS resources in each set. The two SRS resources can be in the same spatial relationship or have the same port information, or there are no restrictions. In this case, it is not necessary to indicate the SRI domain code point information; the SRI domain of the DCI is indicated by 3 bits / 4 bits for the SRI domain code point value.
[0127] Table 4 SRI Domain Code Point Information Indication Table
[0128]
[0129] For example, as shown in Table 5 below, if the SRS resource set configured on the network side for codebook transmission is configured with only one SRS resource, then there is no need for the MAC CE to further indicate this correspondence. That is, in the table, the number of bits in the SRI field of the DCI is determined by the number of SRS resource sets. If the SRS resource set is 1, then the SRI field of the DCI is indicated by 0 bits for the SRI field code point value (i.e., no indication is required). If the SRS resource set is 2, then the SRI field of the DCI is indicated by 2 bits for the SRI field code point value.
[0130] Table 5 SRI Domain Code Point Information Indication Table

[0145] Based on the number of bits in the SRI field, the range of values for the SRI field code points in the DCI is determined.
[0146] Optionally, the number of bits in the SRI field can be determined based on the number of at least one SRI field code point information. For example, if the number of SRI field code points is 5, then the number of bits in the SRI field can be at least 3 bits, and the value range of the SRI field code point can be 000 to 111, that is, 0 to 7. For example, if the number of SRI field code points is 4, then the number of bits in the SRI field can be at least 2 bits, and the value range of the SRI field code point can be 00 to 11, that is, 0 to 4.

[0360] Figure 3 This is a second schematic flowchart of the PUSCH transmission method provided in the embodiments of this application, as shown below. Figure 3 As shown, the method includes the following steps:
[0361] Step 300,
[0362] The network-side terminal sends the first instruction information;
[0363] The first indication information is used to instruct the terminal to determine the target transmission resource configuration indicated by the first indication information in at least one transmission resource configuration;
[0364] The first indication information includes at least one of the following:
[0365] Detection reference signal (SRS) resource indication information;
[0366] Precoding matrix indicates TPMI indication information;
[0367] Phase tracking reference signal (PTRS) transmission port indication information.
[0368] The configuration of at least one transmission resource is determined based on at least one of the following:
[0369] Prior instructions from the network side;
[0370] Protocol predefined;
[0371] Pre-configured;
[0372] RRC layer indication;
[0373] MAC layer indication.
[0374] Optionally, the target transmission resource configuration can be the resource configuration used by the terminal to transmit PUSCH.
[0375] Optionally, for codebook-based PUSCH transmission, the network side can configure an SRS resource set for the UE to obtain based on uplink transmission CSI. Each SRS resource set can contain two SRS resources. The two SRS resources can contain the same number of ports, i.e., both can be ports 1, 2, and 4. These two SRS resources can be configured to correspond to different beams.
[0376] The network side can obtain uplink channel information by measuring SRS on different SRS resources, and select parameters such as spatial relationship, precoding matrix, power control, and MCS for PUSCH transmission for the UE based on this uplink channel information. These transmission parameters are indicated to the UE through the SRI / TPMI / TPC / MCS fields in the DCI format0_1 / 0_2 of the PUSCH scheduling. During PUSCH transmission, the same spatial relationship and port as the SRS resources indicated by the SRI field can be used.
[0377] Optionally, for non-codebook transmission, each SRS resource set used for non-codebook transmission can be configured with 4 SRS resources, and all SRS resources can have 1 port. Each SRS resource set can be configured with associated CSI-RS for the UE to measure the downlink channel. Based on channel reciprocity, the UE can assume the measured downlink channel as the uplink channel and calculate the uplink transmission precoding matrix based on this channel information. The UE can then use this precoding matrix to precode the SRS and send it to the network side. The network side can determine the precoding used by the UE for PUSCH transmission based on the measured precoded SRS and indicate this through the SRI field of the DCI for scheduling PUSCH. That is, the SRI field can indicate the subset of all precoded SRS resources sent by the UE, thus indicating the precoding matrix used for PUSCH transmission.
[0378] Optionally, the network side can indicate SRS resources through SRS resource indication information in the first indication information, so that the terminal can use the same spatial relationship and port transmission PUSCH as the SRS resource.
[0379] Optionally, the network side can indicate the precoding matrix through the TPMI indication information in the first indication information, so that the terminal can use the precoding matrix to precode the SRS.
[0380] Optionally, the network side can indicate the PTRS transmission port through the PTRS transmission port indication information in the first indication information, and indicate in the PTRS-DMRS association field which layer the PTRS is uploaded to;
[0381] Optionally, one layer can correspond to one DM-RS port.
[0382] Optionally, the network side can indicate the corresponding information in the resource configuration for transmitting PUSCH through any one or any combination of the TPMI indication information, PTRS transmission port indication information, and TPMI indication information in the first indication information.
[0383] Optionally, after determining the target transmission resource configuration, that is, after determining the resource configuration used for transmitting PUSCH, PUSCH can be transmitted based on the resource configuration used for transmitting PUSCH.
[0384] In this embodiment, at least one of SRS resource indication information, TPMI indication information, and PTRS transmission port indication information is used to indicate the target transmission resource configuration for PUSCH transmission to the terminal, thereby reducing the bit overhead of the SRI field and / or TPMI field when configuring PUSCH transmission resources.
