[0052] For ease of description, the following description will be made using a base station as an example of an access network device. In the following description, "if ...", "under ..." and "when ..." can be used interchangeably without causing confusion.

[0053] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0054] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation using a terminal device and a network device as an example. As shown in FIG1 , a communication system 100 may include a network device 101 and terminal devices 102 and 103. For simplicity, FIG1 illustrates only two terminal devices and one network device as an example, but the embodiments of the present application are not limited thereto.

[0055] In the embodiment of the present application, existing services or future services can be transmitted between the network device 101 and the terminal devices 102 and 103. For example, these services may include but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0056] The terminal device 102 may send data to the network device 101, for example, using an authorized or unauthorized transmission mode. The network device 101 may receive data sent by one or more terminal devices 102 and provide feedback to the terminal device 102, such as ACK / NACK information. The terminal device 102 may confirm the end of the transmission process, or may continue with new data transmission, or may retransmit the data based on the feedback information.

[0057] It is worth noting that FIG1 shows that both terminal devices 102 and 103 are within the coverage range of network device 101, but the present application is not limited thereto. Both terminal devices 102 and 103 may not be within the coverage range of network device 101, or one terminal device 102 may be within the coverage range of network device 101 while the other terminal device 103 is outside the coverage range of network device 101.

[0058] Currently, NR system uplink transmission is limited by coverage and throughput. Although the NR standard supports 4 or even more PUSCH transmissions, commercial mobile terminals are typically equipped with only one or two transmit antennas due to power amplifier costs and the size of commercial mobile terminals.

[0059] Currently, advanced mobile terminals can support 3Tx in the same frequency band. Mobile terminals that support 3Tx can significantly improve uplink throughput, which can provide a better user experience for dense services.

[0060] The NR system manages and configures SRS using SRS resource sets. Depending on the usage, the base station can configure multiple SRS resource sets for the UE. Each SRS resource set contains one or more SRS resources, and each SRS resource can be configured as 1, 2, 4, or 8 SRS ports. The configuration information for each SRS resource set includes a usage indicator, which can be configured as at least one of beam management, codebook, non-codebook, and antenna switching.

[0061] The current NR protocol standard supports SRS resource configuration for 1 / 2 / 4 / 8 ports. That is, the base station can only indicate SRS resources for 1 / 2 / 4 / 8 ports and cannot support the SRS resource configuration and indication requirements of 3-port 3Tx mobile terminals. Therefore, the current NR protocol standard cannot achieve uplink throughput enhancement for 3Tx mobile terminals.

[0062] The following describes the terms involved in this application, but the following explanations do not constitute a limitation on the embodiments of this application.

[0063] In the embodiments of the present application, the high-layer signaling may be, for example, radio resource control (RRC) signaling; for example, an RRC message, including, for example, an MIB, system information, or a dedicated RRC message; or an RRC information element (RRC IE). The high-layer signaling may also be, for example, MAC (Medium Access Control) signaling; or a MAC control element (MAC CE). However, the present application is not limited thereto.

[0064] In the following description, to avoid confusion, the terms "PUCCH" and "physical uplink control channel" or "uplink control information" are interchangeable, and the terms "PUSCH" and "physical uplink data channel" or "uplink data" are also interchangeable. Furthermore, transmitting or receiving the PUSCH can be understood as transmitting or receiving uplink data carried by the PUSCH. Furthermore, the terms "transmit" and "send" are interchangeable.

[0065] Embodiments of the first aspect

[0066] An embodiment of the present application provides a signal processing method, which is described from the perspective of a terminal device.

[0067] FIG2 is a schematic diagram of a signal processing method according to an embodiment of the present application. As shown in FIG2 , the method includes:

[0068] 201. A terminal device receives configuration information from a network device, where the configuration information includes first configuration information indicating a 3-port probing reference signal resource; and

[0069] 202. The terminal device performs physical uplink shared channel transmission according to the 3-port sounding reference signal resource information indicated by the first configuration information.

[0070] It is worth noting that FIG2 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG2 above.

[0071] According to the above embodiment, the terminal device receives configuration information from the network device, the configuration information including first configuration information for indicating a 3-port sounding reference signal resource, and performs physical uplink shared channel transmission according to the 3-port sounding reference signal resource information indicated by the first configuration information. Thus, it is possible to support PUSCH transmission of a 3-port terminal device, improve the performance and efficiency of PUSCH transmission, and achieve enhanced uplink throughput.

[0072] In one embodiment, the terminal device may send capability-related information to the network device through terminal capability reporting. This capability-related information may include information about uplink Tx antenna capabilities, supported SRS transmission capability information, etc. Based on the terminal capability reporting, the network device may understand the terminal device's SRS transmission capability and the number of uplink Tx antennas / ports.

[0073] Therefore, the network device can configure SRS resources and SRS resource sets for the terminal device; the relevant SRS configuration can be indicated to the terminal device via RRC signaling. When the terminal device's uplink is 3Tx, SRS needs to support 3-port transmission. 3-port SRS transmission can be achieved by bundling multiple SRS resources together (bundled SRS resources).

[0074] In some embodiments, the 3-port SRS resource includes an SRS resource group including a bundled 2-port SRS resource and a single-port SRS resource, or three bundled single-port SRS resources.

[0075] In some embodiments, the configuration information from the network device may further include second configuration information for configuring at least one SRS resource set. The SRS resource set may include single-port SRS resources and / or dual-port SRS resources, and the SRS resources in the SRS resource set may be bundled into at least one SRS resource group.

[0076] Take the SRS resource set including single-port SRS resources and 2-port SRS resources as an example:

[0077] In the SRS resource set, the SRS resource group may be explicitly or implicitly configured by RRC.

[0078] Taking display configuration as an example, the second configuration information may include information for indicating SRS resources included in the SRS resource group.

[0079] Taking implicit configuration as an example, 2-port SRS resources and / or single-port SRS resources may be bundled into an SRS resource group in a predefined manner.

[0080] For example, if the SRS resource set includes two SRS resources (one two-port SRS resource and one single-port SRS resource), the two SRS resources may form an SRS resource group.

[0081] For another example, if the SRS resource set includes 4 SRS resources, for example, 2-port SRS resource, single-port SRS resource, 2-port SRS resource, single-port SRS resource, or single-port SRS resource, 2-port SRS resource, single-port SRS resource, 2-port SRS resource, then the first 2 SRS resources can form the first SRS resource group, and the last 2 SRS resources can form the second SRS resource group.

[0082] For another example, if the SRS resource set includes four SRS resources, for example, a 2-port SRS resource, a 2-port SRS resource, a single-port SRS resource, and a single-port SRS resource, or a single-port SRS resource, a single-port SRS resource, a 2-port SRS resource, and a 2-port SRS resource, then the first 2-port SRS resource and the first single-port SRS resource can form a first SRS resource group, and the second 2-port SRS resource and the second single-port SRS resource can form a second SRS resource group. The present application is not limited to this, and SRS resources can also be formed into SRS resource groups in other ways.

[0083] Take the SRS resource set including a single-port SRS resource as an example:

[0084] In the SRS resource set, the SRS resource group may be explicitly or implicitly configured by RRC.

[0085] Taking display configuration as an example, the second configuration information may include information for indicating SRS resources included in the SRS resource group.

[0086] Taking implicit configuration as an example, single-port SRS resources can be bundled into an SRS resource group in a predefined manner.

[0087] For example, if the SRS resource set includes three single-port SRS resources, these three SRS resources may form an SRS resource group.

[0088] For another example, if the SRS resource set includes 6 single-port SRS resources, the first 3 single-port SRS resources can form the first SRS resource group, and the last 3 single-port SRS resources can form the second SRS resource group. The present application is not limited thereto, and SRS resources can also be formed into SRS resource groups in other ways.

[0089] In some embodiments, the terminal device may be configured with an SRS resource set, where the SRS resource set may include at least one SRS resource group. The first configuration information is used to indicate an SRS resource group in the SRS resource set.

[0090] In some embodiments, the first configuration information may include an SRI (SRS Resource Indicator) field of the DCI, that is, a sounding reference signal resource indicator field.

[0091] For example, when the 3Tx terminal device is a single panel terminal and / or in a single transmission point (single TRP) solution, for codebook-based uplink transmission, the network device may configure an SRS resource set for the terminal device.

[0092] In the DCI for dynamically scheduled PUSCH transmission, the network device can indicate SRS resources to the terminal device through the SRI field. For a 3-Tx terminal device, the SRI indicates a group of bundled SRS resources in the SRS resource set, and the group of SRS resources corresponds to a 3-port SRS.

[0093] In some embodiments, the overhead of the SRI field in the DCI is bits, where N bundled SRS The number of SRS resource groups in the SRS resource set.

[0094] For example, an SRS resource set may include 1 SRS resource group (N bundled SRS=1). The SRS resource group may include one 2-port SRS resource and one single-port SRS resource bundled together, or the SRS resource group may include three single-port SRS resources bundled together.

[0095] In this case, the SRI overhead in the DCI is 0 bits. The network device and the terminal device assume that the bundled SRS resources are indicated.

[0096] Table 1 is an example of an SRS resource set configuration according to an embodiment of the present application. As shown in Table 1, one SRS resource set is configured, which includes one SRS resource group. This SRS resource group may include SRS resource #0 (one port) and SRS resource #1 (two ports), or may include SRS resource #0 (one port), SRS resource #1 (one port), and SRS resource #2 (one port). In this case, the SRI can be defaulted, thereby saving signaling overhead.

[0097] Table 1 An example of the configuration of the SRS resource set in the embodiment of the present application

[0098] In some embodiments, one SRS resource set may also include more than one SRS resource group.

[0099] In some embodiments, the more than one SRS groups may each include a bundled 2-port SRS resource and a single-port SRS resource, or may each include a bundled 3 SRS resources. The present application is not limited thereto, and the more than one SRS groups may also include a bundled 2-port SRS resource and a single-port SRS resource, or may include a bundled 3 SRS resources.

[0100] For example, an SRS resource set includes two SRS resource groups (N bundled SRS =2). In this case, the SRI overhead in the DCI is 1 bit. The codepoint of the SRI field can indicate an SRS resource group.

[0101] Table 2 is another example of the configuration of an SRS resource set in an embodiment of the present application. As shown in Table 2, one SRS resource set is configured, and the one SRS resource set includes two SRS resource groups. One SRS resource group may include SRS resource #0 (1 port) and SRS resource #1 (2 ports), and the other SRS resource group may include SRS resource #2 (1 port) and SRS resource #3 (2 ports); alternatively, one SRS resource group may include SRS resource #0 (1 port), SRS resource #1 (1 port), and SRS resource #2 (1 port), and the other SRS resource group may include SRS resource #3 (1 port), SRS resource #4 (1 port), and SRS resource #5 (1 port).

[0102] Table 2 Another example of the configuration of the SRS resource set in the embodiment of the present application

[0103] In this case, the SRI overhead in the DCI is 1 bit. Table 3 shows an example of the mapping relationship between the SRI and the bundled SRS resource group in an embodiment of the present application. As shown in Table 3, the codepoint value of the SRI field can be the same as the SRS resource group index value. The present application is not limited to this, and the codepoint value of the SRI field and the SRS resource group index value can also have other corresponding relationships.

[0104] Table 3 is an example of the mapping relationship between SRI and bundled SRS resource groups in an embodiment of the present application.

[0105] In some embodiments, a terminal device may be configured with more than one SRS resource set. For example, the terminal device may be configured with two SRS resource sets (a first resource set and a second resource set). The first resource set and the second resource set each include at least one SRS resource group. The first configuration information is for one SRS resource group in the first resource set and one SRS resource group in the second resource set.

[0106] In some embodiments, the first resource set may include more than one SRS resource group, each of the more than one SRS resource group includes a bundled 2-port SRS resource and a single-port SRS resource, or each includes three bundled single-port SRS resources.

[0107] In some embodiments, the second resource set may include more than one SRS resource group, each of which includes a bundled 2-port SRS resource and a single-port SRS resource, or includes three bundled single-port SRS resources. The present application is not limited thereto, and the more than one SRS group in the first resource set and / or the second resource set may also include a bundled 2-port SRS resource and a single-port SRS resource, or three bundled SRS resources.

[0108] In some embodiments, the first configuration information may include an SRI field of the DCI, the SRI field including a first indication field and a second indication field. The first indication field is used to indicate an SRS resource group in the first resource set, and the second indication field is used to indicate an SRS resource group in the second resource set. One SRS resource group corresponds to one 3-port SRS.

[0109] For example, when a 3Tx terminal device is a multi-panel terminal and / or in a multi-transmission point (multi-TRP) solution, for codebook-based uplink transmission, the network device can configure two SRS resource sets for the terminal device. Each SRS resource set corresponds to a panel or a TRP. For each SRS resource set, the SRS resource configuration and SRS resource bundling method within the resource set can be the same as the single panel and single TRP cases described above, and will not be further explained here.

[0110] In some embodiments, the overhead of the first indication field of the SRI field in the DCI is bits, where N bundled SRS 1 is the number of SRS resource groups in the first resource set.

[0111] For example, the first resource set includes one SRS resource group, and the overhead of the first indication field in the DCI is 0 bit; or, the first resource set includes two SRS resource groups, and the overhead of the first indication field in the DCI is 1 bit.

[0112] In some embodiments, the overhead of the second indication field of the SRI field in the DCI is bits, where N bundled SRS 2 is the number of SRS resource groups in the second resource set.

[0113] For example, the second resource set includes one SRS resource group, and the overhead of the second indication field in the DCI is 0 bit; or, the second resource set includes two SRS resource groups, and the overhead of the second indication field in the DCI is 1 bit.

[0114] Table 4 is another example of the configuration of an SRS resource set in an embodiment of the present application. As shown in Table 4, when two SRS resource sets are configured, each SRS resource set may include one or two SRS resource groups, each of which may include one single-port SRS resource and one two-port SRS resource, or three single-port SRS resources.

[0115] Table 4 Another example of the configuration of the SRS resource set in the embodiment of the present application

[0116] At this time, the overhead of the first indication field in the DCI, the mapping relationship between the codepoint of the first indication field and the bundled SRS resource group can be the same as the aforementioned single panel and single TRP cases; similarly, the overhead of the second indication field in the DCI, the mapping relationship between the codepoint of the second indication field and the bundled SRS resource group can be the same as the aforementioned single panel and single TRP cases.

[0117] For example, when the first resource set includes one SRS resource group, the overhead of the first indicator field in the DCI is 0 bits. When the first resource set includes two SRS resource groups, the overhead of the first indicator field in the DCI is 1 bit. The codepoint value of the first indicator field can be the same as the index value of the SRS resource group in the first resource set, or the codepoint value of the first indicator field and the index value of the SRS resource group in the first resource set can also have other corresponding relationships.

[0118] In some embodiments, the first configuration information may include an srs-ResourceIndicator in an RRC message, ie, a sounding reference signal resource indicator.

[0119] In some embodiments, the terminal device may be configured with an SRS resource set, and the SRS resource indicator is used to indicate an SRS resource group in the SRS resource set.

[0120] For example, when the 3Tx terminal device is a single panel terminal and / or in single TRP transmission, for codebook-based uplink transmission, the network device can configure an SRS resource set for the terminal.

[0121] An SRS resource set configured by the network device for the terminal device may include an SRS resource group (N bundled SRS =1) or two SRS resource groups (N bundled SRS=2). Each SRS resource group may include one 2-port SRS resource and one single-port SRS resource bundled together, or each SRS resource group may include three single-port SRS resources bundled together.

[0122] In a PUSCH transmission with a configuration grant, the network device can indicate SRS resources to the terminal through the RRC-configured srs-ResourceIndicator. For a 3-Tx terminal device, the srs-ResourceIndicator can indicate a group of bundled SRS resources in the SRS resource set, which corresponds to a 3-port SRS.

[0123] In some embodiments, the terminal device may be configured with two SRS resource sets, where the two SRS resource sets include a first resource set and a second resource set, and the first resource set and the second resource set each include at least one SRS resource group.

[0124] The SRS resource indicator includes a first indicator and a second indicator, the first indicator is used to indicate an SRS resource group in the first resource set, and the second indicator is used to indicate an SRS resource group in the second resource set.

[0125] For example, when the 3Tx terminal device is a multi-panel terminal and / or in multi-TRP transmission, for codebook-based uplink transmission, the network device can configure two SRS resource sets for the terminal device. Each SRS resource set corresponds to a panel or a TRP. For each SRS resource set, the SRS resource configuration and SRS resource bundling method within the resource set can be the same as the single panel and single TRP cases described above and will not be further explained here.

[0126] In RRC, the network device may indicate a group of bundled SRS resources in the first resource set through srs-ResourceIndicator, and may indicate a group of bundled SRS resources in the second resource set through srs-ResourceIndicator2.

[0127] In some embodiments, the UE performs PUSCH transmission according to the 3-port SRS resource information indicated by the first configuration information, which may mean: in the codebook-based uplink transmission mode, the UE determines the corresponding 3-port SRS resources according to the first configuration information, and the terminal device uses the transmitting antenna and beam corresponding to the 3-port SRS resources to perform PUSCH transmission.

[0128] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.
