Description

Method and communication device for configuring resources

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on February 8, 2024, with application number 202410178122.3 and application name “Method and communication device for configuring resources”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and more particularly, to a method for configuring resources and a communication device. Background Art

[0003] Currently, before a network device communicates with a terminal, the network device needs to configure resources for the terminal so that the terminal can send or receive control information and data on the corresponding resources.

[0004] The process of configuring resources for a terminal by a network device generally includes: The network configures multiple resource sets for the terminal, each resource set including multiple resources, and the resources within a resource set are configured with the same number of antenna ports. Furthermore, the number of antenna ports configured for each resource is obtained from the range of antenna port numbers corresponding to that resource. For example, if the range of antenna port numbers is (1, 2, 4), the number of antenna ports configured for each resource can only be a value within that range.

[0005] Currently, for terminals that support a three-transmitting antenna architecture, when network equipment configures resources for the terminal, researchers have found that the number of antenna ports required by the terminal's port capability conflicts with the existing protocol. The main reason is that the number of antenna ports required by the terminal does not fall within the value range of the number of antenna ports corresponding to the resources specified by the existing protocol. As a result, based on traditional configuration schemes, it is impossible to enable network equipment and terminals to support the uplink three-antenna port configuration. Summary of the Invention

[0006] The present application provides a method and a communication device for configuring resources, which achieve the purpose of forming an equivalent new number of antenna ports by coordinating the first number of antenna ports with the deactivated antenna ports.

[0007] To achieve the above objectives, this application adopts the following technical solutions:

[0008] In a first aspect, a method for configuring resources is provided. The method may be executed by a network device, or may be executed by a chip configured in the network device.

[0009] Specifically, the method includes: sending first resource configuration information, the first resource configuration information indicates at least one resource, and a first antenna port number corresponding to the resource, the first antenna port number is greater than the antenna port number of the terminal, the first antenna port number indicates a corresponding number of antenna port identifiers, and the first antenna port number is determined according to the port capability of the terminal; sending first indication information or receiving second indication information reported by the terminal, wherein the first indication information and the second indication information both carry a first antenna port identifier and / or a second antenna port identifier, the first antenna port identifier is an identifier of a deactivated antenna port, and the second antenna port identifier is an identifier of an activated antenna port, wherein the number of first antenna port identifiers is the difference between the first antenna port number and the antenna port number of the terminal, and the number of second antenna port identifiers is the same as the antenna port number of the terminal.

[0010] It should be noted that the port capability of the terminal can be the antenna port of the terminal enabled by the network device, or the terminal can actively report the port capability to the network device, or the terminal can report the port capability to the network device in response to a request from the network device.

[0011] When the number of antenna ports required by the terminal's port capabilities conflicts with the existing protocol, the network device configures each resource with a first antenna port number greater than the terminal's antenna port number. The network device then uses the first indication information or the second indication information to indicate which antenna ports to deactivate, ensuring that the final number of activated antenna ports is the same as the terminal's antenna port number. This solution combines the first antenna port number with the deactivated antenna ports to create an equivalent new number of antenna ports, thereby meeting the terminal's uplink transmission requirements.

[0012] Among them, the number of antenna ports required by the terminal's port capability conflicts with the existing protocol. It can be understood that the number of antenna ports required to be configured by the terminal does not exist within the value range of the number of antenna ports corresponding to the resources determined based on the existing protocol.

[0013] For a terminal that supports a 3-transmitting antenna architecture, the number of first antenna ports corresponding to the resources configured by the network device for the terminal can be 4, and then 1 deactivated antenna port is indicated through the first indication information or the second indication information, and the remaining 3 activated antenna ports are equivalent to configuring 3 antenna ports for the terminal, so that the network device and the terminal can support the uplink 3-antenna port configuration.

[0014] In one possible implementation, after receiving the second indication information reported by the terminal, the method further includes: sending third indication information to the terminal, the third indication information indicating that the network device has obtained the first antenna port identifier and / or the second antenna port identifier carried by the second indication information.

[0015] After receiving the second indication information, the network device sends a third indication information to the terminal to confirm that the network device knows which antenna ports have been deactivated. This completes information sharing and mutual confirmation between the terminal and the network device. When the terminal receives the third indication information, the network device and the terminal can perform resource configuration based on the same deactivated antenna ports.

[0016] In a possible implementation manner, the first indication information is carried in downlink control signaling.

[0017] In the embodiment of the present application, the downlink control signaling is, for example, radio resource control (RRC) signaling, media access control control element (MAC CE) signaling, downlink control information (DCI) signaling, etc.

[0018] In a possible implementation manner, the second indication information is carried in uplink control signaling.

[0019] In the embodiment of the present application, the uplink control signaling is, for example, radio resource control (RRC) signaling, media access control control element (MAC CE) signaling, uplink control information (UCI) signaling, etc.

[0020] In a possible implementation, the number of antenna ports of the terminal is 3, and the number of first antenna ports is 4.

[0021] Among them, one deactivated antenna port is indicated by the first indication information or the second indication information, so that the purpose of forming an equivalent number of 3 antenna ports can be achieved to meet the demand of uplink 3-port transmission.

[0022] In a possible implementation manner, the at least one resource is a sounding reference signal SRS resource.

[0023] In one possible implementation, the method further includes calculating the cyclic shifts corresponding to the first N antenna port identifiers among the antenna port identifiers arranged in order of size according to the corresponding number indicated by the first antenna port number, the cyclic shift being used to generate a signal sequence to be sent, where N is the number of antenna ports of the terminal.

[0024] In this application, no matter which identifiers of the deactivated antenna ports are, when calculating the cyclic shift of each antenna port, the identifier of the activated antenna port is mapped to the first N antenna port identifiers, and then the cyclic shift corresponding to each of the first N antenna port identifiers is calculated.

[0025] In a possible implementation, the frequency domain starting position of each antenna port of each resource is calculated according to the identifier of the activated antenna port of each resource and the number of antenna ports of the terminal.

[0026] In a traditional solution, each resource corresponding to multiple antenna ports needs to calculate the corresponding frequency domain starting position. However, in the embodiment of the present application, the frequency domain resource starting position of the deactivated antenna port is not calculated.

[0027] In a second aspect, a method for configuring resources is provided. The method can be executed by a terminal, or can also be executed by a chip configured in the terminal.

[0028] Specifically, the method includes: receiving first resource configuration information, the first resource configuration information indicates at least one resource, and a first antenna port number corresponding to the resource, the first antenna port number is greater than the antenna port number of the terminal, the first antenna port number indicates a corresponding number of antenna port identifiers, and the first antenna port number is determined according to the port capability of the terminal; receiving first indication information or reporting second indication information to a network device, wherein the first indication information and the second indication information both carry a first antenna port identifier and / or a second antenna port identifier, the first antenna port identifier is an identifier of a deactivated antenna port, and the second antenna port identifier is an identifier of an activated antenna port, wherein the number of first antenna port identifiers is the difference between the first antenna port number and the antenna port number of the terminal, and the number of second antenna port identifiers is the same as the antenna port number of the terminal; performing resource configuration according to the first resource configuration information and the first indication information or the second indication information.

[0029] In the embodiment of the present application, the port capability of the terminal may be the antenna port of the terminal enabled by the network device, or the terminal may actively report the port capability to the network device, or the terminal may respond to a request from the network device to report the port capability to the network device.

[0030] When configuring resources, the terminal receives the first resource configuration information and obtains the first antenna port number of each resource configuration, and information such as the first antenna port number is greater than the terminal's antenna port number. The terminal then determines the identifier of the activated antenna port using the identifier of the deactivated antenna port indicated by the first indication information or the second indication information, and performs frequency domain starting position calculation and cyclic shift calculation on the activated antenna port. The first antenna port number is combined with the deactivated antenna port to form an equivalent new antenna port number, thereby meeting the terminal's uplink transmission requirements.

[0031] For a terminal that supports a 3-transmit antenna architecture, the terminal receives the first antenna port number 4 corresponding to the resources configured by the network device, and then determines the remaining 3 activated antenna ports through 1 deactivated antenna port indicated by the first indication information or the second indication information. This is equivalent to configuring 3 antenna ports for the terminal, so that the network device and the terminal can support the uplink 3-antenna port configuration.

[0032] In one possible implementation, after reporting the second indication information to the network device, the method further includes: receiving third indication information sent by the network device, the third indication information indicating that the network device has obtained the first antenna port identifier and / or the second antenna port identifier carried by the second indication information.

[0033] After receiving the third indication, the terminal can confirm that the network device has learned which antenna ports have been deactivated. This completes information sharing and mutual confirmation between the terminal and the network device, paving the way for the network device and the terminal to subsequently configure resources based on the same deactivated antenna ports.

[0034] In a possible implementation manner, the first indication information is carried in downlink control signaling.

[0035] In the embodiment of the present application, the downlink control signaling is, for example, radio resource control (RRC) signaling, media access control control element (MAC CE) signaling, downlink control information (DCI) signaling, etc.

[0036] In a possible implementation manner, the second indication information is carried in uplink control signaling.

[0037] In the embodiment of the present application, the uplink control signaling is, for example, radio resource control (RRC) signaling, media access control control element (MAC CE) signaling, uplink control information (UCI) signaling, etc.

[0038] In a possible implementation, the number of antenna ports of the terminal is 3, and the number of first antenna ports is 4.

[0039] Among them, one deactivated antenna port is indicated by the first indication information or the second indication information, so that the purpose of forming an equivalent number of 3 antenna ports can be achieved to meet the terminal's uplink 3-port transmission requirement.

[0040] In a possible implementation manner, at least one resource is a sounding reference signal SRS resource.

[0041] In one possible implementation, the method further includes: calculating the cyclic shifts corresponding to the first N antenna port identifiers in the antenna port identifiers arranged in order of size according to the corresponding number indicated by the first antenna port number, the cyclic shift being used to generate a signal sequence to be sent, where N is the number of antenna ports of the terminal.

[0042] In this application, no matter which identifiers of the deactivated antenna ports are, when calculating the cyclic shift of each antenna port, the identifier of the activated antenna port is mapped to the first N antenna port identifiers, and then the cyclic shift corresponding to each of the first N antenna port identifiers is calculated.

[0043] In a possible implementation, the method further includes: calculating a frequency domain starting position of each antenna port of each resource according to an identifier of an activated antenna port of each resource and the number of antenna ports of the terminal.

[0044] In this application, no matter which identifiers of the deactivated antenna ports are, when calculating the cyclic shift of each antenna port, the identifier of the activated antenna port is mapped to the first N antenna port identifiers, and then the cyclic shift corresponding to each of the first N antenna port identifiers is calculated.

[0045] In a possible implementation manner, the method further includes: in PUSCH transmission, linearly scaling the PUSCH non-zero power according to the number of activated antenna ports indicated by the second antenna port identifier.

[0046] In traditional solutions, PUSCH non-zero power is generally linearly scaled based on the number of antenna ports in resource configuration. In this solution, the number of first antenna ports is greater than the number of antenna ports in the terminal, so the linear scaling of PUSCH non-zero power is not performed based on the number of first antenna ports. Instead, the second antenna port identifier, that is, the number of activated antenna port identifiers, is used to linearly scale PUSCH non-zero power.

[0047] In a third aspect, a method for configuring resources is provided. The method can be executed by a network device, or can also be executed by a chip configured in the network device.

[0048] Specifically, the method includes: generating second resource configuration information, the second resource configuration information indicating multiple first resource sets, and the number of second antenna ports corresponding to each resource in the first resource set; wherein the sum of the number of second antenna ports corresponding to each resource in the first resource set is the same as the number of antenna ports of the terminal, and the spatial domain information and power control parameters of each resource in the first resource set are the same; and sending the second resource configuration information to the terminal.

[0049] This solution supports combined transmission of the number of ports corresponding to different resources, and by configuring the same airspace information and power control parameters for different resources, it ensures that sending signals through different resources achieves the same result as sending signals through the same resource.

[0050] In a possible implementation manner, the second resource configuration information includes a first resource set identifier corresponding to each resource in the first resource set.

[0051] This solution indicates that the second resource configuration information indicates the identifier of the first resource set corresponding to each resource, wherein the second resource configuration information can represent the correspondence between the first resource set and each resource in the first resource set through ResourceGroup configuration or Resource configuration.

[0052] In a possible implementation, the second resource configuration information further includes a second resource set identifier corresponding to each resource in the first resource set, where the second resource set identifier is an identifier of the second resource set to which the first resource set belongs.

[0053] The essence of this solution is that the second resource configuration information includes the first resource set identifier and the second resource set identifier corresponding to each resource in the first resource set. The correspondence between the first resource set and each resource in the first resource set can be represented by ResourceSet configuration or Resource configuration.

[0054] In one case, multiple first resource sets belong to one second resource set. In another case, multiple second resource sets are configured, each of which includes multiple first resource sets. In another case, resources in at least two second resource sets can form one first resource set. These three cases are described below.

[0055] In a possible implementation, among multiple first resource sets, the second resource set identifiers corresponding to resources in some of the first resource sets are the same, and the second resource set identifiers corresponding to resources in some of the first resource sets are different.

[0056] The essence of this solution is to configure multiple second resource sets, each of which includes multiple first resource sets.

[0057] In a possible implementation, the second resource set identifiers corresponding to the resources in the same first resource set are not completely the same.

[0058] The essence of this solution is that resources in at least two second resource sets can form a first resource set.

[0059] In a possible implementation manner, the number of second antenna ports corresponding to various resources in the same second resource set is the same.

[0060] This solution restricts multiple resources within a first resource set to come from different ResourceSets. For each second resource set, existing protocol constraints are still applied, ensuring that multiple resources within the same ResourceSet have the same number of antenna ports. This solution makes minimal changes to existing protocol specifications and does not increase signaling overhead.

[0061] In a possible implementation, the number of second antenna ports corresponding to each resource in different second resource sets is not completely the same.

[0062] In this solution, the number of antenna ports corresponding to resources in different second resource sets does not affect each other and can be the same, different, or partially the same. By flexibly setting the number of second antenna ports corresponding to each resource, the types of antenna port numbers supported by the resource configuration method can be expanded.

[0063] In a possible implementation manner, the spatial information and power control parameter parts of the resources in the multiple first resource sets belonging to the same second resource set are the same or different.

[0064] In this solution, in one case, different airspace information and power control parameters are configured for multiple ResourceGroups under one ResourceSet, wherein multiple Resources under each ResourceGroup are configured with the same airspace information and power control parameters.

[0065] In another case, a ResourceSet configures different airspace information and power control parameters for multiple resources to meet the airspace information and power control parameter requirements of the ResourceGroup corresponding to these resources. In this case, the configuration of this ResourceSet corresponds to the configuration of one or more other ResourceSets.

[0066] For example, refer to Figure 6 , where ResourceSet1 configures different airspace information and power control parameters for Resource1-1 and Resource1-2. Correspondingly, ResourceSet2 configures different airspace information and power control parameters for Resource2-1 and Resource2-2. At the same time, it is also necessary to ensure that the airspace information and power control parameters of Resource1-1 and Resource2-1 within the same ResourceGroup1 are identical, and that the airspace information and power control parameters of Resource1-2 and Resource2-2 within the same ResourceGroup2 are identical.

[0067] In a possible implementation, the numbers of second antenna ports corresponding to the resources in the first resource sets are all the same, or partially the same, or all different.

[0068] In the embodiment of the present application, there is no limitation on the number of antenna ports corresponding to each resource in the first resource set. The number of antenna ports may be set in accordance with existing protocol regulations, customized, or freely combined.

[0069] In one possible implementation, the spatial domain information includes a serving cell identifier and a reference signal identifier, and the reference signal includes a synchronization signal block index (Synchronization Signal Block Index, SSB-Index), a channel state information reference signal index (Channel State Information Reference Signal Index, CSI-RS-Index), an SRS resource identifier (SRS ResourceID), and an uplink bandwidth part (UplinkBWP).

[0070] In a possible implementation, the power control parameters include a configuration parameter (alpha) for path loss compensation, a target received power (p0), a path loss reference signal (pathlossReferenceRS), and an SRS power control adaptation state (SRS-powercontroladjustmentstates).

[0071] In one possible implementation, the method also includes: during the downlink scheduling process, sending downlink control information to the terminal, the downlink control information carrying a resource indication field (SRS Resource Indicator, SRI) or a resource set indication field (SRS Resource Set Indicator, SRSI), wherein the bit width of the resource indication field (SRI) or the bit width of the resource set indication field (SRSI) corresponds to the number of first resource sets, and the target first resource set indicated by the resource indication field (SRI) or the resource set indication field (SRSI) is used to configure PUSCH transmission.

[0072] In the traditional scheme, downlink scheduling is performed on a resource basis, while in this scheme, downlink scheduling is performed on a combination of the number of antenna ports of each resource in the ResourceGroup as a whole. Therefore, the indication field indicating the ResourceGroup is different from the traditional scheme. This scheme performs downlink scheduling through the resource indication field (SRI) or the resource set indication field (SRSI), and the number of bits of the resource indication field (SRI) or the number of bits of the resource set indication field (SRSI) is determined based on the number of ResourceGroups.

[0073] Furthermore, in the conventional solution, PUSCH transmission is configured by resources indicated by downlink scheduling, whereas in the present solution, PUSCH transmission is configured by a port combination of various resources in the first resource set indicated by downlink scheduling.

[0074] In a fourth aspect, a method for configuring resources is provided. The method can be executed by a terminal, or can also be executed by a chip configured in the terminal.

[0075] Specifically, the method includes: receiving second resource configuration information, the second resource configuration information indicating multiple first resource sets, and the number of second antenna ports corresponding to each resource in the first resource set; wherein the sum of the number of second antenna ports corresponding to each resource in the first resource set is the same as the number of antenna ports of the terminal, and the spatial domain information and power control parameters of each resource in the first resource set are the same; performing resource configuration according to the second resource configuration information.

[0076] This solution supports combined transmission of the number of ports corresponding to different resources, and by configuring the same airspace information and power control parameters for different resources, it ensures that sending signals through different resources achieves the same result as sending signals through the same resource.

[0077] In a possible implementation manner, the second resource configuration information includes a first resource set identifier corresponding to each resource in the first resource set.

[0078] This solution indicates that the second resource configuration information indicates the identifier of the first resource set corresponding to each resource, wherein the second resource configuration information can represent the correspondence between the first resource set and each resource in the first resource set through ResourceGroup configuration or Resource configuration.

[0079] In a possible implementation, the second resource configuration information further includes a second resource set identifier corresponding to each resource in the first resource set, where the second resource set identifier is an identifier of the second resource set to which the first resource set belongs.

[0080] The essence of this solution is that the second resource configuration information includes the first resource set identifier and the second resource set identifier corresponding to each resource in the first resource set. The correspondence between the first resource set and each resource in the first resource set can be represented by ResourceSet configuration or Resource configuration.

[0081] In a possible implementation, among multiple first resource sets, the second resource set identifiers corresponding to resources in some of the first resource sets are the same, and the second resource set identifiers corresponding to resources in some of the first resource sets are different.

[0082] The essence of this solution is to configure multiple second resource sets, each of which includes multiple first resource sets.

[0083] In a possible implementation, the second resource set identifiers corresponding to the resources in the same first resource set are not completely the same.

[0084] The essence of this solution is that resources in at least two second resource sets can form a first resource set.

[0085] In a possible implementation manner, the number of second antenna ports corresponding to various resources in the same second resource set is the same.

[0086] This solution restricts multiple resources within a first resource set to come from different ResourceSets. For each second resource set, existing protocol constraints are still applied, ensuring that multiple resources within the same ResourceSet have the same number of antenna ports. This solution makes minimal changes to existing protocol specifications and does not increase signaling overhead.

[0087] In a possible implementation, the number of second antenna ports corresponding to each resource in different second resource sets is not completely the same.

[0088] In this solution, the number of antenna ports corresponding to resources in different second resource sets does not affect each other and can be the same, different, or partially the same. By flexibly setting the number of second antenna ports corresponding to each resource, the types of antenna port numbers supported by the resource configuration method can be expanded.

[0089] In a possible implementation manner, the spatial information and power control parameter parts of the resources in the multiple first resource sets belonging to the same second resource set are the same or different.

[0090] In this solution, in one case, different airspace information and power control parameters are configured for multiple ResourceGroups under one ResourceSet.

[0091] In a possible implementation, the numbers of second antenna ports corresponding to the resources in the first resource sets are all the same, or partially the same, or all different.

[0092] In the embodiment of the present application, there is no limitation on the number of antenna ports corresponding to each resource in the first resource set. The number of antenna ports may be set in accordance with existing protocol regulations, customized, or freely combined.

[0093] In one possible implementation, the spatial domain information includes a serving cell identifier and a reference signal identifier, and the reference signal includes a synchronization signal block index (Synchronization Signal Block Index, SSB-Index), a channel state information reference signal index (Channel State Information Reference Signal Index, CSI-RS-Index), an SRS resource identifier (SRS ResourceID), and an uplink bandwidth part (UplinkBWP).

[0094] In a possible implementation, the power control parameters include a configuration parameter (alpha) for path loss compensation, a target received power (p0), a path loss reference signal (pathlossReferenceRS), and an SRS power control adaptation state (SRS-powercontroladjustmentstates).

[0095] In one possible implementation, the method further includes: during the downlink scheduling process, sending downlink control information to the terminal, the downlink control information carrying a resource indication field (SRI) or a resource set indication field (SRSI), wherein the bit width of the resource indication field (SRI) or the bit width of the resource set indication field (SRSI) corresponds to the number of first resource sets; and configuring PUSCH transmission according to the target first resource set indicated by the resource indication field (SRI) or the resource set indication field (SRSI).

[0096] In the traditional scheme, PUSCH transmission is configured through the resources indicated by the downlink scheduling, while this scheme performs downlink scheduling based on the combination of the number of antenna ports of each resource in the ResourceGroup as a whole. Therefore, the indication field indicating the ResourceGroup is different from the traditional scheme. This scheme performs downlink scheduling through the resource indication field or the resource set indication field, and the number of bits of the resource indication field or the number of bits of the resource set indication field is determined based on the number of ResourceGroups.

[0097] In a possible implementation, during PUSCH transmission, the PUSCH non-zero power is linearly scaled according to a ratio of the number of antenna ports performing PUSCH transmission to the number of combined ports corresponding to the target first resource set.

[0098] In an embodiment of the present application, not all antenna ports corresponding to the first resource set are necessarily used for PUSCH transmission. In this case, the terminal linearly scales the number of antenna ports for PUSCH non-zero power transmission within a ResourceGroup according to the ratio of the number of antenna ports for PUSCH non-zero power transmission within a ResourceGroup to the number of combined ports corresponding to the ResourceGroup. The number of combined ports is the sum of the number of second antenna ports corresponding to all resources in the ResourceGroup.

[0099] In a fifth aspect, a method for configuring resources is provided. The method can be executed by a network device, or can also be executed by a chip configured in the network device.

[0100] Specifically, the method includes: generating first resource configuration information, the first resource configuration information indicating at least one resource and a first number of antenna ports corresponding to the resource, the first number of antenna ports being equal to the number of antenna ports of the terminal, and the first number of antenna ports being determined based on the port capability of the terminal; and sending the first resource configuration information to the terminal.

[0101] In the present application solution, the changes to existing resources are very small, and only the number of configured ports of one resource is added. The changes to the protocol are small while achieving 3-port transmission.

[0102] In a sixth aspect, a method for configuring resources is provided. The method can be executed by a terminal, or can also be executed by a chip configured in the terminal.

[0103] Specifically, the method includes: receiving first resource configuration information, the first resource configuration information indicating at least one resource and a first number of antenna ports corresponding to the resource, the first number of antenna ports being equal to the number of antenna ports of the terminal, and the first number of antenna ports being determined based on the port capability of the terminal; and performing resource configuration according to the first resource configuration information.

The embodiments of the present application do not limit the spectrum resources used between the network device and the terminal.

[0135] To facilitate understanding, the terms involved in this application are first explained.

[0136] (1) Resources

[0137] In this application, resources can be understood as time domain, frequency domain and code domain resources for sending a certain signal or data.

[0138] Taking the sounding reference signal (SRS) resource as an example, in this application, SRS resources can be understood as the time domain, frequency domain, and code domain resources for transmitting SRS. Among them, SRS is an uplink reference signal sent by the terminal to the network device. After receiving the SRS, the network device can obtain the uplink (UL) channel from the terminal to the network device based on the SRS, or obtain the downlink (DL) channel from the network device to the terminal based on channel reciprocity.

[0139] It should be noted that the technical solution of the present application can be applied not only to configuring SRS resources, but also to configuring physical downlink control channel (PDCCH) resources, configuring physical downlink shared channel (PDSCH) resources, configuring physical uplink control channel (PUCCH) resources, configuring physical uplink shared channel (PUSCH) resources, etc. The technical solution of the present application does not limit the type of configured resources.

[0140] (2) Antenna port

[0141] Antenna ports are used to carry data signals. Antenna ports are multiplexed and work in parallel. It should be noted that, unless otherwise specified in this application, antenna ports refer to logical antenna ports.

[0142] Taking the configuration of SRS resources as an example, based on existing protocol regulations, the network device will configure SRS ResourceSet and SRS resources for the terminal. Generally, a ResourceSet corresponds to one or more SRS resources, and the number of antenna ports corresponding to each SRS resource in a ResourceSet is the same. The number of antenna ports corresponding to each SRS resource is Each antenna port corresponds to a specific time-frequency code resource. Ideally, each antenna port occupies a different time-frequency code domain resource to reduce mutual interference. Each antenna port is mapped to one or more physical antenna elements of the terminal.

[0143] It should be noted that terminal antenna configurations include two types: nTnR, where the terminal includes n transmit antennas and n receive antennas. In this case, based on existing protocol specifications, one SRS resource is typically configured to correspond to n antenna ports, with each antenna port corresponding to each transmit / receive antenna. nTmR, where the terminal includes n transmit antennas and m receive antennas. Based on existing protocol specifications, each SRS resource includes n antenna ports. Each antenna port corresponds to a specific time-frequency resource, and ideally, the SRS ports are orthogonal.

[0144] (3) Cyclic shift α of antenna port

[0145] Taking the SRS sequence as an example, the SRS pilot sequence corresponding to the terminal is pre-configured in the terminal. The SRS pilot sequence corresponding to the terminal is used as the basic sequence. The basic sequence is cyclically shifted according to the cyclic shift of each antenna port to obtain the SRS pilot sequence corresponding to each antenna port, so that the SRS pilot sequence corresponding to each antenna port has very good autocorrelation and very low cross-correlation.

[0146] Among them, the antenna port p i The cyclic shift α i The calculation formula is as follows:

[0147] in,

[0148] Among them, CS is cyclic shift, represents the cyclic shift parameter of the i-th port, represents the maximum number of cyclic shifts, It is cyclic shift frequency hopping, which is 0 when not configured. f System frame number, The timeslot number within the frame used for the subcarrier spacing μ configuration (where the subcarrier spacing μ configuration is Δf=2 μ ×15[kHz]), l′ is the subscript of the OFDM symbol relative to the reference position, K is the coefficient, is the number of antenna ports of the terminal.

[0149] (4) Frequency domain starting position

[0150] Frequency domain starting position The calculation formula is as follows:

[0151] in,

[0152] in, Frequency hopping compensation value in the frequency domain, FH is frequency hopping, is the RB-level partial frequency sounding compensation value, n shift is the frequency domain offset value, is the number of subcarriers corresponding to each resource section, is the function corresponding to comb offset hopping (combOffsetHopping), n f is the system frame number, The timeslot number within the frame used for the subcarrier spacing μ configuration (where the subcarrier spacing μ configuration is Δf=2 μ ×15[kHz]), l′ is the subscript of the OFDM symbol relative to the reference position, K TC For the comb score,

[0153] Among them, K TC and The corresponding relationship is shown in Table 1, which is a corresponding table of comb scores and maximum cyclic shifts.

[0154] Table 1

[0155] From the above formula, it can be seen that the starting position of the frequency domain is based on the antenna port p i Odd-even grouping will be performed, and the frequency domain starting position will be calculated using different formulas for odd-numbered antenna port groups or even-numbered antenna port groups.

[0156] Combing is a way to distinguish different subcarriers in the frequency domain. Different combs represent different subcarrier positions. SRS resources achieve frequency division multiplexing between antenna ports by assigning different combs to different antenna ports. Specifically, combs are subcarriers extracted at equal intervals in the frequency domain. The extraction interval is called the comb fraction K. TC , based on existing agreement provisions, usually K TC ∈(2,4,8). For example, when K TC When the value is 2, the frequency domain can be divided into two combs.

[0157] (5) PUSCH transmission

[0158] During the downlink scheduling process, the network device sends downlink control information (DCI) to the terminal. The DCI carries a resource indicator. When the resource to be configured is an SRS resource, the resource indicator is an SRS resource indicator (SRI), where the SRI field can be an SRS ResourceID field. The number of bits occupied by SRI is directly related to the number of SRS resources included in a ResourceSet. Specifically, in non-codebook mode, SRI occupies In codebook mode, Among them L max is the number of transmission layers, N SRS is the number of SRS resources.

[0159] For the power of PUSCH transmission, according to 38.213, for uplink power control, in the current PUSCH power scaling factor calculation, when the uplink full power transmission (ul-FullPowerTransmission) configuration of PUSCH-Config is not full power mode 1 (fullpowermode1), full power mode 2 (fullpowermode2), or full power mode (fullpowermode), when the usage of ResourceSet is 'Codebook' and the number of antenna ports is not 1, the terminal performs linear scaling according to the ratio of the number of antenna ports with non-zero PUSCH power to the maximum number of antenna ports corresponding to one SRS resource.

[0160] Currently, before a network device communicates with a terminal, the network device needs to configure resources for the terminal so that the terminal can send or receive control information and data on the corresponding resources.

[0161] The process of configuring resources from a network device to a terminal generally includes: the network configures multiple resource sets to the terminal, each resource set includes multiple resources, and the number of antenna ports configured for the resources under each resource set is the same. For example, when a network device configures SRS resources to a terminal, based on the existing protocol, the number of antenna ports corresponding to the SRS resources is in, That is to say, the number of antenna ports corresponding to the SRS resources can only be selected from these three values.

[0162] This configuration is well-suited for terminals with a two-transmit antenna architecture, but the existing two-transmit antenna architecture limits the terminal's uplink throughput. With the evolution of terminals, researchers have discovered that a three-transmit antenna architecture can significantly improve the terminal's uplink throughput. Although the existing NR (New Radio) protocol supports terminals with four or even eight transmit antennas, the likelihood of commercialization in the short term is low. Therefore, to improve terminal uplink throughput, researchers have begun researching terminals with a three-transmit antenna architecture, which is more likely to be commercialized in the near term.

[0163] Among them, for the terminal that supports 3 transmit antenna architecture, its antenna configuration is 3T. When configuring resources for the terminal, researchers found that based on the terminal's port capability, the network equipment needs to configure 3 antenna ports for each SRS resource. However, based on the existing protocol regulations, the number of antenna ports corresponding to each SRS resource is Because the number of antenna ports corresponding to SRS resources does not include the value 3, it is impossible to directly configure the terminal with 3 antenna ports. In other words, the number of antenna ports required by the terminal's port capabilities conflicts with the existing protocol. Therefore, based on the traditional configuration scheme, it is impossible for network equipment and terminals to support the uplink 3-antenna port configuration.

[0164] To solve this problem, an embodiment of the present application provides a method for configuring resources, in which the network device configures a first antenna port number for each resource that is greater than the number of antenna ports of the terminal, and then indicates the deactivated antenna ports through first indication information or second indication information, so that the number of antenna ports ultimately activated is the same as the number of antenna ports of the terminal. When the number of antenna ports required to be configured for the terminal's port capability conflicts with the existing protocol, this solution uses the first antenna port number to coordinate with the deactivated antenna ports to achieve the purpose of forming an equivalent new number of antenna ports, thereby meeting the requirements of uplink 3-port transmission.

[0165] For example, for a terminal that supports a 3-transmitting antenna architecture, the number of first antenna ports corresponding to the resources configured by the network device for the terminal can be 4, and then 1 deactivated antenna port is indicated through the first indication information or the second indication information, and the remaining 3 activated antenna ports are equivalent to configuring 3 antenna ports for the terminal, so that the network device and the terminal can support uplink 3-port transmission.

[0166] The following describes in detail the method for configuring resources provided in the embodiments of the present application with reference to the accompanying drawings.

[0167] Please refer to Figure 2, which shows a schematic interactive diagram of a method 200 for configuring resources provided in an embodiment of the present application. Each step of the method 200 will be described in detail below.

[0168] In the embodiment of the present application, the method 200 is described by taking a terminal and a network device as the execution subjects of the method 200. As an example but not a limitation, the execution subjects of the method 200 may also be the chip corresponding to the terminal and the chip corresponding to the network device.

[0169] In S202, the network device sends first resource configuration information to the terminal.

[0170] Among them, the first resource configuration information indicates at least one resource and the first number of antenna ports corresponding to each resource. The first number of antenna ports is greater than the number of antenna ports of the terminal. The first number of antenna ports indicates a corresponding number of antenna port identifiers. The first number of antenna ports is determined based on the port capability of the terminal.

[0171] Optionally, the at least one resource is a sounding reference signal SRS resource. Optionally, the at least one resource may also be, for example, a PUSCH resource, a PDSCH resource, a PUCCH resource, a PDCCH resource, etc. This application does not limit the specific type of the resource.

[0172] In this embodiment of the present application, the first resource configuration information is generated by a network device based on existing protocol specifications. The number of first antenna ports corresponding to each resource is determined based on the terminal's port capabilities. When configuring resources for different terminals, it is necessary to first obtain the port capabilities of each terminal. The port capabilities can be indicated by the number of logical transmit antennas supported by the terminal.

[0173] The terminal may proactively report the port capability to the network device, or the terminal may respond to a request from the network device to report the port capability to the network device. In the embodiment of the present application, the method 200 may further include S201 before S202.

[0174] In S201 , the terminal reports port capabilities to the network device.

[0175] For example, if a terminal supports three logical transmit antennas (hereinafter referred to as transmit antennas), the port capability reported by the terminal to the network device will include information about three antenna ports, indicating that the terminal needs to configure three antenna ports. For another example, if a terminal supports eight transmit antennas, the port capability reported by the terminal to the network device will include information about eight antenna ports, indicating that the terminal needs to configure eight antenna ports.

[0176] Optionally, in an embodiment of the present application, the network device may enable the antenna ports of the terminal. In other words, the network device independently determines the number of antenna ports that the terminal needs to enable. In this case, the number of antenna ports of the terminal in the embodiment of the present application refers to the number of antenna ports enabled by the network device.

[0177] In one implementation, the network device directly sends enabling information to the terminal without requiring the terminal to report its port capabilities. For example, if a terminal supports 8T, the network device will not consider the terminal's port capabilities and will directly enable the terminal's antenna port to 5T. Accordingly, in this solution, the terminal has 5 antenna ports.

[0178] In another implementation, after receiving the port capability reported by the terminal, the network device determines a value smaller than the port capability reported by the terminal as the number of antenna ports enabled by the network device for the terminal.

[0179] For example, if the terminal reports that it supports 8T, and the network device determines based on various factors that the terminal's antenna port is 5T, then in this solution, the number of antenna ports on the terminal is 5.

[0180] In an embodiment of the present application, after the network device obtains the port capabilities reported by the terminal, it determines the first number of antenna ports based on the terminal's port capabilities and existing protocol provisions. In an embodiment of the present application, the existing protocol specifies a range of values ​​for the number of antenna ports corresponding to the resource. The network device may select a value greater than the number of antenna ports of the terminal from the range of values ​​for the number of antenna ports corresponding to the resource as the first number of antenna ports. The number of antenna ports of the terminal is the same as the number of logical transmit antennas supported by the terminal.

[0181] Optionally, the first number of antenna ports is a value in a value range of the number of antenna ports corresponding to the resource that is greater than the number of antenna ports of the terminal and closest to the number of antenna ports of the terminal.

[0182] For example, existing protocols specify that the number of antenna ports corresponding to a resource ranges from (1, 2, 4). If the terminal's port capability supports three transmit antennas, the network device can select 4 from this range as the first antenna port number corresponding to the resource when configuring the resource for the terminal.

[0183] For another example, the existing protocol stipulates that the value range of the number of antenna ports corresponding to a certain resource is (1, 2, 4, 8). At this time, the port capability of the terminal is to support 6 transmitting antennas. When the network device configures the resource for the terminal, it can take 8 from the value range as the first antenna port number corresponding to the resource.

[0184] It should be noted that the value ranges of the number of antenna ports corresponding to different types of resources may be different.

[0185] Next, the implementation process of the first resource configuration information indicating the at least one resource in the embodiment of the present application is described.

[0186] In one implementation, the first resource configuration information may indicate the at least one resource (Resource) through a Resource configuration, wherein each Resource corresponds to a Resource configuration that records various Resource information, such as a Resource ID, the number of Resource ports, combing and cyclic shift configuration, time domain resource configuration, frequency domain resource configuration, precoding configuration, etc. In this embodiment of the present application, the number of Resource ports is defined as the number of first antenna ports. Optionally, the number of first antenna ports corresponding to the multiple Resources is the same.

[0187] In another implementation, the first resource configuration information can indicate the at least one resource through a two-level configuration of a resource set (ResourceSet) and a resource (Resource). The network device can configure one or more ResourceSets for the terminal; each ResourceSet can be configured with one or more Resources. Each ResourceSet corresponds to a ResourceSet configuration, which records various information about the ResourceSet, such as ResourceSetID, Resource type (e.g., periodic, semi-persistent, and non-periodic), usage (e.g., beam management, codebook, non-codebook, antenna selection, etc.), power control related parameters, etc. At the same time, each Resource corresponds to a Resource configuration, which records various information about the Resource, such as ResourceID, number of Resource ports, combing and cyclic shift configuration, time domain resource configuration, frequency domain resource configuration, precoding configuration, etc. In the embodiment of the present application, the number of Resource ports is defined as the number of first antenna ports. Optionally, each Resource in the same ResourceSet corresponds to the same number of first antenna ports.

[0188] In the embodiment of the present application, the number of configurable Resources in each ResourceSet is related to the port capabilities supported by the terminal or the number of antenna ports enabled by the network device for the terminal.

[0189] Optionally, the information recorded in the resource configurations of multiple resources under a ResourceSet is not exactly the same.

[0190] Optionally, the number of Resources included in different ResourceSets may be the same, partially the same, or completely different.

[0191] Optionally, the number of first antenna ports corresponding to the Resources under different ResourceSets may be the same, or partially the same, or completely different, but all are greater than the number of antenna ports of the terminal.

[0192] Optionally, the information recorded in the ResourceSet configurations of different ResourceSets is not completely the same.

[0193] In the embodiment of the present application, the first antenna port number can be used to determine the antenna port identifier, where the antenna port identifier can be understood as an antenna port ID, an antenna port number, or an antenna port number.

[0194] Taking the configuration of PDCCH resources as an example, for example, if the number of the first antenna port configured by the network device for the PDCCH resource is 5, the identifiers of the corresponding antenna ports are accumulated starting from 2000 and can be represented as {2000, 2001, 2002, 2003, 2004} respectively.

[0195] The following describes the principles for determining antenna port identifiers in uplink and downlink.

[0196] In the downlink, the antenna port identifier corresponding to each resource can be determined according to the following principles:

[0197] PDSCH resources: The antenna port identifier is 1000+i, where i cycles from 0 to N-1, and N is the number of the first antenna port.

[0198] PDCCH resource: The antenna port identifier is 2000+i, where i cycles from 0 to N-1, and N is the number of the first antenna port.

[0199] CSI-RS (Channel State Information-Reference Signal) resources: The antenna port identifier is 3000+i, where i cycles from 0 to N-1, and N is the number of the first antenna port.

[0200] SSB (Synchronization Signal Block) resources / PBCH (Physical Broadcast Channel) resources: The antenna port identifier is 4000+i, where i cycles from 0 to N-1, and N is the number of the first antenna port.

[0201] In the uplink, the antenna port identifier corresponding to each resource can be determined according to the following principles:

[0202] PUSCH resources / DMRS (Demodulation Reference Signal) resources: The antenna port identifier is 1000+i, where i cycles from 0 to N-1, and N is the number of the first antenna port.

[0203] SRS resource: The antenna port identifier is 1000+i, where i cycles from 0 to N-1, and N is the number of the first antenna port.

[0204] PUCCH resource: The antenna port identifier is 1000+i, where i cycles from 0 to N-1, and N is the number of the first antenna port.

[0205] PRACH (Physical Random Access Channel) resources: The antenna port identifier is 1000+i, where i cycles from 0 to N-1, and N is the number of the first antenna port.

[0206] For ease of understanding, the following description is given by taking the resource indicated by the first resource configuration information as an SRS resource as an example.

[0207] For example, if the network device obtains that the terminal's port capability supports three transmit antennas, when configuring SRS resources for the terminal, the network device configures a first antenna port number for each SRS resource using a value from the value range (1, 2, 4) corresponding to the SRS resource that is larger than and closest to the terminal's antenna port number, i.e., the first antenna port number is 4. Based on the aforementioned principle for determining antenna port identifiers corresponding to SRS resources, the corresponding number of antenna port identifiers indicated by the first antenna port number can be expressed as {1000, 1001, 1002, 1003}.

[0208] It should be noted that the first resource configuration information may be sent via downlink control signaling, where the downlink control signaling is, for example, RRC, MAC CE, DCI, etc.

[0209] In S203, the network device sends first indication information to the terminal.

[0210] The first indication information carries a first antenna port identifier and / or a second antenna port identifier, the first antenna port identifier is an identifier of a disabled antenna port, and the second antenna port identifier is an identifier of an enabled antenna port, wherein the number of first antenna port identifiers is the difference between the number of first antenna ports and the number of antenna ports of the terminal, and the number of second antenna port identifiers is the same as the number of antenna ports of the terminal.

[0211] In an embodiment of the present application, when the network device generates the first resource configuration information, it has determined that the number of first antenna ports corresponding to each resource is not equal to the number of antenna ports of the terminal. In this case, the network device needs to send a first indication information to the terminal to deactivate (disable) one or more of the multiple antenna ports corresponding to the first number of antenna ports.

[0212] In one implementation, in an embodiment of the present application, the first indication information is carried in downlink control signaling. Downlink control signaling is, for example, radio resource control (RRC) signaling, media access control control element (MAC CE) signaling, downlink control information (DCI) signaling, etc. The signaling corresponding to the first indication information and the signaling corresponding to the first resource configuration information may be different or the same.

[0213] In another implementation, during resource configuration, the first resource configuration information and the first indication information may be sent in a predefined sending order. The predefined sending order may be indicated by the network device to the terminal, or may be determined by negotiation between the terminal and the network device, or may be determined based on a protocol.

[0214] In another implementation, during the process of configuring resources, the first resource configuration information and the first indication information may be sent simultaneously.

[0215] In another implementation, during the resource configuration process, the first indication information may be appended to the first resource configuration information and sent to the terminal as a part of the first resource configuration information.

[0216] In this embodiment of the present application, the first indication information may carry both the first antenna port identifier and the second antenna port identifier. For example, the number of antenna port identifiers corresponding to the first antenna port number indication is {1000, 1001, 1002, 1003}. The first indication information carries the first antenna port identifier {1001} and the second antenna port identifier {1000, 1002, 1003}.

[0217] It should be noted that in the embodiment of the present application, the number of antenna port identifiers corresponding to the first antenna port number indication is known. When the first indication information carries the first antenna port identifier, the network device (terminal) can automatically identify the second antenna port identifier. Similarly, when the first indication information carries the second antenna port identifier, the network device (terminal) can automatically identify the first antenna port identifier.

[0218] For example, the number of antenna port identifiers corresponding to the first antenna port number indication is {1000, 1001, 1002, 1003}. The first indication information carries the first antenna port identifier, and the first antenna port identifier is {1001}. The network device (terminal) can then automatically determine that the remaining antenna port identifiers (i.e., the second antenna port identifiers) are {1000, 1002, 1003} in order.

[0219] For another example, the number of antenna port identifiers corresponding to the first antenna port number indication is {1000, 1001, 1002, 1003}. The first indication information carries a second antenna port identifier, and the second antenna port identifier is {1000, 1001, 1003}. The network device (terminal) can automatically determine that the remaining antenna port identifier (i.e., the first antenna port identifier) ​​is {1002}.

[0220] Therefore, the first indication information only needs to carry one of the first antenna port identifier and the second antenna port identifier, which can reduce the number of fields in the first indication information and reduce overhead.

[0221] In addition, it should be noted that in the embodiment of the present application, the number of first antenna port identifiers can be one or more, and the number of first antenna port identifiers is determined by the difference between the number of first antenna ports and the number of antenna ports of the terminal.

[0222] Please refer to Figure 3, which shows a schematic diagram of resource configuration based on the identifiers of deactivated antenna ports. For example, the corresponding number of antenna port identifiers indicated by the first antenna port number is {1000, 1001, 1002, 1003}. If the first antenna port identifier is {1001}, that is, the identifier of the deactivated antenna port is {1000}, the network device (terminal) removes {1001} from the identifiers of the four antenna ports indicated by the first antenna port number, and then only configures resources for the remaining antenna ports {1001, 1002, 1003}.

[0223] If the identifier of the deactivated antenna port is {1001}, the network device (terminal) removes {1001} from the identifiers of the four antenna ports indicated by the first antenna port number, and then only configures resources for the remaining {1000, 1002, 1003}.

[0224] If the identifier of the deactivated antenna port is {1002}, the network device (terminal) removes {1002} from the identifiers of the four antenna ports indicated by the first antenna port number, and then only configures resources for the remaining {1000, 1001, 1003}.

[0225] If the identifier of the deactivated antenna port is {1003}, the network device (terminal) removes {1003} from the identifiers of the four antenna ports indicated by the first antenna port number, and then only configures resources for the remaining {1000, 1001, 1002}.

[0226] In an embodiment of the present application, the network device determines the antenna ports to be deactivated and informs the terminal through the first indication information, so that the terminal can determine which antenna ports need to be activated through the first indication information to facilitate resource configuration.

[0227] In another embodiment of the present application, the terminal may also determine the antenna port to be deactivated by itself and report it to the network device. In this case, the method 200 further includes S204.

[0228] In S204, the terminal sends second indication information to the network device.

[0229] The second indication information carries a first antenna port identifier and / or a second antenna port identifier, the first antenna port identifier is the identifier of a deactivated antenna port, and the second antenna port identifier is the identifier of an activated antenna port, wherein the number of first antenna port identifiers is the difference between the number of first antenna ports and the number of antenna ports of the terminal, and the number of second antenna port identifiers is the same as the number of antenna ports of the terminal.

[0230] In an embodiment of the present application, when the terminal receives the first resource configuration information, it can be determined that the number of first antenna ports corresponding to each resource in the first resource configuration information is not equal to the number of antenna ports of the terminal. In this case, the terminal can determine the deactivated (disabled) antenna port or the activated (enabled) antenna port based on its own resource utilization, and send the second indication information to the network device based on this.

[0231] In one implementation, in an embodiment of the present application, the second indication information is carried in uplink control signaling.

[0232] The uplink control signaling includes, for example, Radio Resource Control (RRC) signaling, Media Access Control Control Element (MAC CE) signaling, uplink control information (UCI) signaling, and the like.

[0233] It should be noted that, in the embodiment of the present application, the uplink control signaling carrying the second indication information and the downlink control signaling carrying the first resource configuration information may be different or the same.

[0234] In one implementation, if the terminal does not receive the first indication information within a preset time period after receiving the first resource configuration information, the terminal determines the deactivated antenna port on its own and reports it to the network device through the second indication information.

[0235] In another implementation, the network device and the terminal may agree in advance that the network device determines the antenna ports to be deactivated and sends them to the terminal. Alternatively, the terminal determines the antenna ports to be deactivated and reports them to the network device. When both parties agree that the terminal determines the antenna ports to be deactivated, after receiving the first resource configuration information, the terminal sends the second indication information to the network device.

[0236] In another implementation, when the terminal receives the first resource configuration information, if the first antenna port identifier and / or the second antenna port identifier indicated by the first indication information is not found in the first resource configuration information, the terminal can determine the deactivated antenna port by itself and report it to the network device through the second indication information.

[0237] In an embodiment of the present application, the terminal reports the second indication information to the network device so that the network device can know which antenna ports the terminal needs to activate, so that the network device can receive the terminal's uplink transmission on the corresponding antenna port.

[0238] In the embodiment of the present application, after the terminal sends the second indication information to the network device, method 200 may further include S205 and S206.

[0239] In S205 , the network device sends third indication information to the terminal.

[0240] After receiving the second indication information, the network device sends third indication information to the terminal. The third indication information indicates that the network device has acquired the first antenna port identifier and / or the second antenna port identifier carried in the second indication information.

[0241] In S206, the terminal receives third indication information sent by the network device.

[0242] In this embodiment of the present application, after receiving the second indication information, the network device sends a third indication information to the terminal to confirm that the network device knows which antenna port is to be deactivated. This completes the information sharing and information confirmation process between the terminal and the network device. This ensures that the terminal and the network device perform resource configuration based on the same first antenna port number and the deactivated antenna port.

[0243] In S207, the terminal performs resource configuration according to the first resource configuration information and the first indication information, or the terminal performs resource configuration according to the first resource configuration information and the second indication information.

[0244] In an embodiment of the present application, when the network device determines to deactivate the antenna port, the terminal performs resource configuration according to the first resource configuration information and the first indication information after receiving the first resource configuration information and the first indication information.

[0245] When the terminal determines to deactivate the antenna port, the terminal performs resource configuration according to the first resource configuration information and the second indication information after sending the second indication information to the network device. Alternatively, the terminal performs resource configuration according to the first resource configuration information and the second indication information after receiving the third indication information.

[0246] In the embodiment of the present application, the network device also needs to configure resources for the terminal on the network side so as to receive the uplink transmission of the terminal on the corresponding resources and antenna ports. Accordingly, the method 200 may further include S208.

[0247] In S208, the network device performs resource configuration according to the first resource configuration information and the first indication information, or the network device performs resource configuration according to the first resource configuration information and the second indication information.

[0248] When the network device determines to deactivate the antenna port, the network device performs resource configuration according to the first resource configuration information and the first indication information after sending the first indication information to the terminal.

[0249] When the terminal determines to deactivate the antenna port, the network device performs resource configuration according to the first resource configuration information and the second indication information after receiving the second indication information, or performs resource configuration according to the first resource configuration information and the second indication information after sending the third indication information to the terminal.

[0250] The following describes a process in which a network device (terminal) performs resource configuration according to the first resource configuration information and the first indication information, or a process in which a network device (terminal) performs resource configuration according to the first resource configuration information and the second indication information in the embodiment itself.

[0251] In one embodiment, the process of resource configuration of a network device (terminal) includes: calculating the cyclic shifts corresponding to the first N antenna port identifiers among the antenna port identifiers arranged in order of size according to the corresponding number indicated by the first antenna port number, the cyclic shifts being used to generate a signal sequence to be sent, where N is the number of antenna ports of the terminal.

[0252] For example, the number of antenna ports of the terminal is 3, at least one resource indicated by the first resource configuration information is an SRS resource, and the number of first antenna ports corresponding to each SRS resource is 4. Combined with the above content, it can be seen that the antenna port identifiers arranged in order of size can be expressed as {1000, 1001, 1002, 1003}. It should be noted that in this application, arranging in order of size means arranging in ascending order from small to large. When calculating the cyclic shift, the first three antenna identification port numbers {1000, 1001, 1002} are taken from the sorting, and the cyclic shift corresponding to each antenna port {1000, 1001, 1002} is calculated respectively.

[0253] It should be noted that when calculating the cyclic shift, the identifier of the deactivated antenna port may not be considered, but the activated antenna port may be mapped to the first N antenna ports. For example, if the identifier of the deactivated antenna port is {1001}, and it can be determined that the identifiers of the activated antenna ports are {1000, 1002, 1003} in sequence, the identifiers of the activated antenna ports {1000, 1002, 1003} will be mapped to the identifiers of the first three antenna ports {1000, 1001, 1002}. is the number of antenna ports of the terminal.

[0254] Among them, the antenna port p i The cyclic shift α i The calculation formula is as follows:

[0255] in,

[0256] in, represents the cyclic shift parameter of the i-th port, represents the maximum number of cyclic shifts, It is cyclic shift frequency hopping, which is 0 when not configured. f System frame number, The timeslot number within the frame used for the subcarrier spacing μ configuration (where the subcarrier spacing μ configuration is Δf=2 μ ×15[kHz]), l′ is the subscript of the OFDM symbol relative to the reference position, K is the coefficient, is the number of antenna ports of the terminal.

[0257] In another embodiment, the process of performing resource configuration by the network device (terminal) includes: calculating the frequency domain starting position of each antenna port of each resource according to the identifier of the activated antenna port of each resource and the number of antenna ports of the terminal.

[0258] It should be noted that, in the embodiment of the present application, the deactivated antenna port does not need to calculate the frequency domain starting position.

[0259] For example, the corresponding number of antenna port identifiers indicated by the first antenna port number is {1000, 1001, 1002, 1003}, and the identifier of the deactivated antenna port is {1001}. Then, the frequency domain starting positions of the activated antenna ports {1000, 1002, 1003} are calculated respectively, and the frequency domain starting position of the antenna port {1001} is not calculated.

[0260] Among them, the antenna port p of a certain resource i The starting position of the frequency domain The calculation formula is as follows:

[0261] in,

[0262] in, Frequency hopping compensation value in the frequency domain, FH is frequency hopping, is the RB-level partial frequency sounding compensation value, n shift is the frequency domain offset value, is the number of subcarriers corresponding to each resource section, is the function corresponding to comb offset hopping (combOffsetHopping), n f is the system frame number, The timeslot number within the frame used for the subcarrier spacing μ configuration (where the subcarrier spacing μ configuration is Δf=2 μ ×15[kHz]), l′ is the subscript of the OFDM symbol relative to the reference position, K TC For the comb score,

[0263] According to the above formula, we can see that The calculation of antenna port p i association.

[0264] Continuing with the above example, the activated antenna ports are identified as {1000, 1002, 1003}, where the network device (terminal) can calculate its corresponding antenna port based on the antenna port {1000}. Then we get the frequency domain starting position corresponding to the antenna port {1000,1002} Then calculate the frequency domain starting position corresponding to antenna port {1003} separately

[0265] In combination with the above disclosure, it can be seen that different formulas are used to calculate the frequency domain starting position for odd-numbered antenna port groups and even-numbered antenna port groups. Therefore, antenna ports {1000, 1002} use the same formula to calculate the frequency domain starting position. The calculation of the frequency domain starting position of antenna port {1002} can refer to the corresponding situation of otherwise in the above formula. Antenna port {1003} uses a different formula to calculate the frequency domain starting position, as shown below:

[0266] In the embodiment of the present application, the frequency domain starting position of the antenna port {1003} is calculated. When the parameters involved It can be calculated using the following formula:

[0267] In traditional solutions, multiple antenna ports corresponding to each resource need to calculate their corresponding frequency domain starting positions separately. However, in the embodiment of the present application, the frequency domain starting position of the deactivated antenna port is not calculated, and only the frequency domain starting position of the activated antenna port is calculated.

[0268] Through the method for configuring resources provided in the embodiment of the present application, the network device configures resources and the first number of antenna ports corresponding to each resource to the terminal based on the existing protocol regulations. When the number of antenna ports required by the port capability of the terminal conflicts with the existing protocol, the network device configures the first number of antenna ports for each resource to be greater than the number of antenna ports of the terminal, and then indicates the deactivated antenna ports through the first indication information or the second indication information, so that the number of antenna ports finally activated is the same as the number of antenna ports of the terminal.

[0269] The number of antenna ports required by the terminal's port capabilities conflicts with existing protocols. For example, if a terminal's port capabilities support three transmit antennas, the required number of antenna ports is 3. However, existing protocols specify that the range of the number of first antenna ports that can be configured for each resource is (1, 2, 4). Therefore, the required number of antenna ports cannot be determined from this range, resulting in a conflict.

[0270] This solution, on the one hand, indicates the deactivated antenna ports so that the number of antenna ports ultimately activated can meet the number of antenna ports required to be configured by the terminal, and on the other hand, can meet the terminal's various needs. For example, when the terminal supports 5T, when configuring resources, each resource is configured with a first number of antenna ports that is greater than the number of antenna ports required to be configured by the terminal, for example, the first number of antenna ports is 8. The first indication information or the second indication information then indicates the deactivated antenna ports, removing 3 deactivated antenna ports from the 8 antenna ports corresponding to the first number of antenna ports. In this way, the final number of activated antenna ports is combined to match the number of antenna ports of the terminal, meeting the uplink 5-port transmission requirement.

[0271] Based on the above embodiment, in an embodiment of the present application, after the terminal completes resource configuration, it can perform uplink transmission, wherein the uplink transmission is, for example, PUSCH transmission. In the PUSCH transmission, the PUSCH non-zero power is linearly scaled according to the number of activated antenna ports indicated by the second antenna port identifier.

[0272] The network device sends a DCI to the terminal, which carries an SRI. The terminal performs uplink transmission based on the resources indicated by the SRI. For ease of description, the resources indicated by the SRI are referred to as target resources below. In the embodiment of the present application, when performing PUSCH transmission, the terminal configures the data carried on the PUSCH based on the relevant parameter information corresponding to the target resource.

[0273] At the same time, the terminal will also linearly scale the PUSCH non-zero power according to the number of activated antenna ports corresponding to the target resource.

[0274] Optionally, the terminal linearly scales the PUSCH non-zero power according to a ratio of the number of antenna ports performing PUSCH non-zero power transmission to the number of activated antenna ports of resources corresponding to the PUSCH transmission.

[0275] For example, the terminal performs PUSCH transmission based on resource 1, where the number of activated antenna ports corresponding to resource 1 is 2 ports, and the number of antenna ports for PUSCH non-zero power transmission is 1 port. Then the terminal linearly scales the PUSCH non-zero power according to the ratio of 1 port to 2 ports.

[0276] That is to say, after the terminal is configured with resources based on the above embodiment, during uplink transmission, the terminal no longer linearly scales the PUSCH non-zero power according to the maximum number of antenna ports corresponding to the resources (which can be understood as the number of first antenna ports), but linearly scales the PUSCH non-zero power according to the number of activated antenna ports. This process does not take into account the number of deactivated antenna ports.

[0277] The embodiment of the present application also provides another method for configuring resources, which is described below. As shown in Figure 4, Figure 4 shows a schematic interaction diagram of a method 400 for configuring resources provided in an embodiment of the present application. Below, each step of the method 400 is described in detail. In the embodiment of the present application, the method 400 is described by taking the terminal and the network device as the execution subjects of the execution method 400 as an example. As an example and not a limitation, the execution subject of the execution method 400 can also be the chip of the corresponding terminal and the chip of the corresponding network device.

[0278] The purpose of the embodiment of the present application is to realize a new number of port uplink transmission based on a multi-port combination, and the number of ports in the combination can be the same or different.

[0279] In S402, the network device generates second resource configuration information.

[0280] The second resource configuration information indicates multiple first resource sets and the number of second antenna ports corresponding to each resource in the first resource set; the sum of the number of second antenna ports corresponding to each resource in the first resource set is the same as the number of antenna ports of the terminal, and the spatial information and power control parameters of each resource in the first resource set are the same.

[0281] Optionally, the at least one resource is a sounding reference signal SRS resource. Optionally, the at least one resource may also be, for example, a PUSCH resource, a PDSCH resource, a PUCCH resource, a PDCCH resource, etc. This application does not limit the specific type of the resource.

[0282] In an embodiment of the present application, a network device may configure one or more first resource sets for a terminal, and each first resource set may be configured with one or more resources. The first resource set supports resource configurations with multiple different numbers of antenna ports. That is, the numbers of second antenna ports corresponding to the resources within a first resource set may be the same, different, or partially the same. On this basis, the numbers of second antenna ports corresponding to the resources within a first resource set are combined so that the resulting number of antenna ports is the same as the number of antenna ports of the terminal, thereby meeting the number of antenna ports required by the terminal.

[0283] The following describes a process of determining the number of second antenna ports corresponding to each resource in the first resource set in an embodiment of the present application.

[0284] In this embodiment of the present application, the total number of antenna ports corresponding to a first resource set is determined based on the terminal's port capability. When configuring resources for a terminal, it is necessary to first obtain the port capability of each terminal in order to determine the total number of antenna ports corresponding to the first resource set. The port capability can be indicated by the number of logical transmit antennas supported by the terminal.

[0285] The terminal may proactively report the port capability to the network device, or the terminal may respond to a request from the network device to report the port capability to the network device. In the embodiment of the present application, the method 400 may further include S401 before S402.

[0286] In S401 , the terminal reports port capabilities to the network device.

[0287] For example, if the terminal supports 3 transmit antennas, the port capability reported by the terminal to the network device includes 3 antenna port information, which means that the number of antenna ports required to be configured by the terminal is 3 ports, that is, the total number of antenna ports corresponding to the first resource set is 3 ports. For another example, if the terminal supports 6 transmit antennas, the port capability reported by the terminal to the network device includes 6 antenna port information, which means that the number of antenna ports required to be configured by the terminal is 6 ports, that is, the total number of antenna ports corresponding to the first resource set is 6 ports.

[0288] Optionally, in an embodiment of the present application, the network device may enable the antenna ports of the terminal. In other words, the network device independently determines the number of antenna ports that the terminal needs to enable. In this case, the number of antenna ports of the terminal in the embodiment of the present application refers to the number of antenna ports enabled by the network device.

[0289] In one implementation, the network device directly sends enabling information to the terminal without requiring the terminal to report its port capabilities. For example, if a terminal supports 8T, the network device will not consider the terminal's port capabilities and will directly enable the terminal's antenna port to 5T. Accordingly, in this solution, the terminal has 5 antenna ports.

[0290] In another implementation, after receiving the port capability reported by the terminal, the network device determines a value smaller than the port capability reported by the terminal as the number of antenna ports enabled by the network device for the terminal.

[0291] For example, if the terminal reports that it supports 8T, and the network device determines based on various factors that the terminal's antenna port is 5T, then in this solution, the number of antenna ports on the terminal is 5.

[0292] In the embodiment of the present application, after obtaining the total number of antenna ports corresponding to the first resource set, it is necessary to configure the number of second antenna ports corresponding to each resource in the first resource set. This process is also related to the number of resources in the first resource set.

[0293] For example, if the first resource set contains three resources and the total number of antenna ports corresponding to the first resource set is 3 ports, then the number of second antenna ports corresponding to the three resources is 1 port. If the first resource set contains two resources and the total number of antenna ports corresponding to the first resource set is 3 ports, then the number of second antenna ports corresponding to one of the two resources is 2 ports, and the number of second antenna ports corresponding to the other resource is 1 port.

[0294] In one implementation, the numbers of second antenna ports corresponding to the various resources in the first resource set may be all the same, or partially the same, or all different.

[0295] It should be noted that there is no necessary connection between the numbers of second antenna ports corresponding to each resource in a first resource set, and therefore they do not constitute a constraint on each other, but it is necessary to satisfy the constraint that the sum of the numbers of second antenna ports corresponding to all resources in a first resource set is equal to the number of antenna ports of the terminal.

[0296] It should be noted that in one embodiment of the present application, the value of the second antenna port number corresponding to each resource in the first resource set must comply with existing protocol specifications. In other words, the existing protocol specifies a range of values ​​for the number of antenna ports corresponding to each resource. Therefore, when configuring the second antenna port number for each resource in the first resource set, the second antenna port number must be within this range.

[0297] For example, if the number of antenna ports corresponding to a certain resource ranges from (1, 2, 4), the number of second antenna ports corresponding to each resource in the first resource set can only be one of the three values.

[0298] For another example, the first resource set includes 3 resources, and the total number of antenna ports corresponding to the first resource set is 7 ports. Then, among the 3 resources, the number of second antenna ports corresponding to resource #1 can be 1 port, the number of second antenna ports corresponding to resource #2 can be 2 ports, and the number of second antenna ports corresponding to resource #3 can be 4 ports. It should be noted that the combination of the number of second antenna ports corresponding to the 3 resources in the first resource set in this example is only an exemplary display. This application may also have other combinations, and this application does not enumerate them exhaustively.

[0299] In another implementation, in an embodiment of the present application, the number of configured ports of resources can be increased in the existing protocol to expand the value range of the number of antenna ports corresponding to the resources specified in the existing protocol, for example, the value range is expanded from (1,2,4) to (1,2,4,8), or the value range is expanded from (1,2,4) to (1,2,3,4), or the value range is expanded from (1,2,4) to (1,2,3,4,8), etc., wherein, in this example, the number of configured ports of the increased resources is only an example and does not constitute a limitation on the number of configured ports of the increased resources in this solution. In an embodiment of the present application, the number of second antenna ports corresponding to each resource in the first resource set can be the number of configured ports of the increased resources.

[0300] For example, if the first resource set includes three resources and the total number of antenna ports corresponding to the first resource set is 7 ports, then among the three resources, the number of second antenna ports corresponding to resource #1 can be 1 port, the number of second antenna ports corresponding to resource #2 can be 3 ports, and the number of second antenna ports corresponding to resource #3 can be 3 ports. Other combinations are possible and are not exhaustive here.

[0301] The following describes the process of determining the first resource set and each resource in the first resource set in an embodiment of the present application.

[0302] In one implementation, the second resource configuration information may indicate the multiple first resource sets via a ResourceGroup configuration. Each ResourceGroup corresponds to a ResourceGroup configuration that records various ResourceGroup information, such as a first resource set identifier (ResourceGroupID), Resource type, usage, and power control-related parameters. The ResourceGroup configuration also includes a ResourceIDlist that lists identifiers, i.e., ResourceIDs, of all resources included in the first resource set (ResourceGroup).

[0303] The second resource configuration information may also indicate resources in the first resource set through a resource configuration. Each resource corresponds to a resource configuration, which includes, for example, a resource identifier (Resource ID), the number of resource ports, combing and cyclic shift configuration, time domain resource configuration, frequency domain resource configuration, precoding configuration, etc. The number of resource ports is the number of second antenna ports.

[0304] In one embodiment, the second resource configuration information includes a first resource set identifier corresponding to each resource in the first resource set.

[0305] The second resource configuration information indicates the identifier of the first resource set corresponding to each Resource. For example, if Resource#1 corresponds to ResourceGroup#2, the second resource configuration information includes the corresponding relationship between Resource#1 and ResourceGroup#2.

[0306] The second resource configuration information may represent the correspondence between the first resource set and each resource in the first resource set through ResourceGroup configuration or Resource configuration.

[0307] Optionally, the first resource set identifier corresponding to each resource in the first resource set is configured in the ResourceGroup configuration. For example, the ResourceGroupID can be marked after each ResourceID listed in the ResourceIDlist. The ResourceGroupID is the ID of the first resource set to which the Resource indicated by the ResourceID belongs.

[0308] Optionally, the first resource set identifier corresponding to each resource in the first resource set is configured in the Resource configuration, wherein, for a certain Resource, its Resource configuration includes a ResourceID. In an embodiment of the present application, a ResourceGroupID may be marked after the ResourceID, and the ResourceGroupID is the ID of the first resource set to which the Resource indicated by the ResourceID belongs.

[0309] In another embodiment, the second resource configuration information further includes a second resource set identifier corresponding to each resource in the first resource set, where the second resource set identifier is an identifier of the second resource set to which the first resource set belongs.

[0310] That is to say, in the embodiment of the present application, the second resource configuration information includes a first resource set identifier and a second resource set identifier corresponding to each resource in the first resource set, and the second resource set identifier is an identifier of the second resource set to which the first resource set belongs.

[0311] In an embodiment of the present application, the second resource configuration information may indicate the second resource set via a ResourceSet configuration. The ResourceSet configuration may include, for example, a second resource set identifier (ResourceSetID), resource type, usage, power control-related parameters, etc. The ResourceSet configuration may also include a ResourceIDlist, which lists identifiers (ResourceIDs) of all resources included in one or more first resource sets (ResourceGroup).

[0312] The number of the second resource sets is 1 or more.

[0313] Optionally, the first resource set identifier and the second resource set identifier corresponding to each resource in the first resource set are configured in the ResourceSet configuration. For a second resource set, the ResourceSet configuration corresponding to the second resource set includes its own ResourceSetID and a ResourceIDlist, which lists the ResourceIDs of one or more resources in the first resource set included in the second resource set. In the embodiment of the present application, the first resource set identifier (ResourceGroupID) can be marked after the ResourceID.

[0314] It can be understood that the second resource set includes one or more first resource sets, and the one or more first resource sets include one or more resources. The first resource set to which each resource belongs can be indicated by the ResourceGroupID marked after the ResourceID.

[0315] It should be noted that the total number of antenna ports corresponding to multiple first resource sets (ResourceGroups) under the same second resource set (ResourceSet) is the same. For example, if a ResourceGroup under a ResourceSet contains a resource combination of 2 ports + 4 ports, then the resource combination schemes of other ResourceGroups under the ResourceSet are all 2 ports + 4 ports.

[0316] Optionally, the first resource set identifier and the second resource set identifier corresponding to each resource in the first resource set are configured in the Resource configuration, wherein, for a certain Resource, its Resource configuration includes a ResourceID. In an embodiment of the present application, the first resource set identifier (ResourceGroupID) and the second resource set identifier (ResourceSetID) can be marked after the ResourceID, and the ResourceGroupID is the ID of the first resource set to which the Resource indicated by the ResourceID belongs. The ResourceSetID is the ID of the second resource set to which the Resource indicated by the ResourceID belongs.

[0317] Optionally, among multiple first resource sets, the second resource set identifiers corresponding to resources in some of the first resource sets are the same, and the second resource set identifiers corresponding to resources in some of the first resource sets are different.

[0318] This solution includes the following situations. The corresponding relationship between each resource in the first resource set and the first resource set and the second resource set in this embodiment is explained below with reference to FIG5 to FIG7.

[0319] 1. If some resources have the same ResourceGroupID, they belong to the same first resource set. If some resources have the same ResourceSetID, the first resource set to which they belong belongs to the second resource set indicated by the ResourceSetID. That is, a second resource set includes a first resource set, and the first resource set includes some resources.

[0320] 2. If some resources have different ResourceGroupIDs, they belong to different first resource sets. If they have the same ResourceSetID, they belong to the same second resource set. In other words, the second resource set includes two or more first resource sets, each of which includes one or more resources.

[0321] As shown in Figure 5, Figure 5 shows a schematic diagram of the correspondence between each resource in a first resource set and the first resource set and the second resource set, wherein the network device is configured with a second resource set ResourceSet1, which includes multiple first resource sets ResourceGroup1, ResourceGroup2, ..., each ResourceGroup includes multiple resources, for example, ResourceGroup1 includes Resource1 and Resource2. Correspondingly, the resources in the same first resource set have the same ResourceGroupID and the same ResourceSetID. The resources in different first resource sets have different ResourceGroupIDs and the same ResourceSetID.

[0322] It should be noted that, when the number of second antenna ports of each resource in the first resource set is different, it means that the number of second antenna ports corresponding to each resource in the second resource set to which the first resource set belongs may be different.

[0323] 3. If some resources have the same ResourceGroupID, they belong to the same first resource set. If some resources have different ResourceSetIDs, they belong to different second resource sets. In other words, resources in the same first resource set come from different second resource sets.

[0324] As shown in Figure 6, Figure 6 shows another schematic diagram of the correspondence between each resource in the first resource set and the first resource set and the second resource set. It can be seen that the two resources Resource1-1 and Resource2-1 contained in ResourceGroup1 come from ResourceSet1 and ResourceSet2 respectively. The two resources Resource1-2 and Resource2-2 contained in ResourceGroup2 come from ResourceSet1 and ResourceSet2 respectively.

[0325] For example, the first resource set includes two resources, namely resource #1 and resource #2, wherein resource #1 corresponds to {ResourceGroup2, ResourceSet1}, and resource #2 corresponds to {ResourceGroup2, ResourceSet3}.

[0326] 4. The ResourceGroupIDs corresponding to some Resources are different, indicating that these Resources belong to different first resource sets. The ResourceSetIDs corresponding to these Resources are different, indicating that these Resources belong to different second resource sets.

[0327] As shown in Figure 7, Figure 7 shows another schematic diagram of the correspondence between each resource in the first resource set and the first resource set and the second resource set. It can be seen that of the three resources Resource1-1, Resource1-2, and Resource2-1 contained in ResourceGroup1, two are from ResourceSet1 and the other is from ResourceSet2. Of the three resources Resource1-3, Resource1-4, and Resource2-3 contained in ResourceGroup2, two are from ResourceSet1 and the other is from ResourceSet2.

[0328] That is, the second resource set identifiers corresponding to the resources in a first resource set may be partially identical and partially different.

[0329] Optionally, the second resource set identifiers corresponding to the resources in the same first resource set are not completely the same, that is, some of the resources in the same first resource set belong to the same second resource set, while others belong to other second resource sets.

[0330] Optionally, the number of second antenna ports corresponding to each resource in the same second resource set is the same.

[0331] As shown in FIG6 , the number of second antenna ports corresponding to Resource1-1 and Resource1-2 of ResourceSet1 is 1 port; the number of second antenna ports corresponding to Resource2-1 and Resource2-2 of ResourceSet2 is 2 ports.

[0332] Optionally, the number of second antenna ports corresponding to each resource in different second resource sets is not exactly the same.

[0333] Please refer to Figure 8, which shows another schematic diagram of the correspondence between each resource in the first resource set and the first resource set and the second resource set. Figure 8 shows three ResourceSets, namely ResourceSet1, ResourceSet2, and ResourceSet3. Among them, the number of second antenna ports corresponding to Resource1-1 and Resource1-2 corresponding to ResourceSet1 is 1 port, and the number of second antenna ports corresponding to Resource2-1 and Resource2-2 corresponding to ResourceSet2 is 2 ports. The number of second antenna ports corresponding to Resource3-1 and Resource3-2 corresponding to ResourceSet3 is 2 ports.

[0334] It can be seen that the number of second antenna ports of the Resources corresponding to ResourceSet2 and ResourceSet3 is the same, the number of second antenna ports of the Resources corresponding to ResourceSet2 and ResourceSet1 is different, and the number of second antenna ports of the Resources corresponding to ResourceSet3 and ResourceSet1 is different.

[0335] FIG8 also exemplarily shows ResourceGroup1 and ResourceGroup2, wherein the three resources in ResourceGroup1 correspond to different ResourceSets, and the three resources in ResourceGroup2 correspond to different ResourceSets.

[0336] During uplink transmission, it is necessary to configure and process the uplink transmission through spatial information and power control parameters. Different configurations correspond to different beam directions. If the beam directions corresponding to the various resources in the first resource set are different, then when the second antenna ports corresponding to multiple resources are combined together, the beams cannot be merged or beam reduction problems may occur. In order to better fuse the beams corresponding to different resources during the multi-port combination process, this application configures the same spatial information and power control parameters for each resource in the same first resource set.

[0337] Among them, the spatial domain information includes the serving cell identifier and the reference signal identifier, and the reference signal includes the synchronization signal block index (Synchronization Signal Block Index, SSB-Index), the channel state information reference signal index (Channel State Information Reference Signal Index, CSI-RS-Index), the SRS resource identifier (SRS ResourceID), and the uplink bandwidth part (UplinkBWP).

[0338] The power control parameters include the configuration parameter (alpha) of the path loss compensation, the target received power (p0), the path loss reference signal (pathlossReferenceRS), and the SRS power control adaptation state (SRS-powercontroladjustmentstates).

[0339] Taking the first resource set indicated by the second resource configuration information as an SRS resource as an example, each SRS resource in the same first resource set is configured with the same spatial information and power control parameters. For the spatial information (SRS-SpatialRelationInfo), each resource in the first resource set is configured with the same servingCellID and referenceSignal, where the referenceSignal includes a synchronization signal block (SSB) index, a channel state information reference signal (CSI-RS) index, a sounding reference signal (SRS) resource identifier, and an uplink bandwidth part (BWP). Each SRS resource in the first resource set uses the same spatial filter.

[0340] Optionally, in an embodiment of the present application, the spatial information and power control parameters of each resource in multiple first resource sets belonging to the same second resource set are partially the same or different.

[0341] Optionally, in an embodiment of the present application, different airspace information and power control parameters may be configured for different first resource sets through ResourceSet configuration.

[0342] For example, ResourceSet#2 includes three first resource sets, represented as ResourceGroup#1, ResourceGroup#2, and ResourceGroup#3, respectively, wherein the spatial domain information and power control parameters of each resource in ResourceGroup#1 and ResourceGroup#2 are the same, while the spatial domain information and power control parameters of each resource in ResourceGroup#1 and ResourceGroup#3 are different, or the spatial domain information and power control parameters of each resource in ResourceGroup#2 and ResourceGroup#3 are different.

[0343] For another example, ResourceSet#2 includes three first resource sets, which are represented as ResourceGroup#1, ResourceGroup#2, and ResourceGroup#3, respectively. The spatial information and power control parameters of the resources corresponding to the three first resource sets are different.

[0344] Based on the above embodiment, in the embodiment of the present application, the second resource configuration information may further indicate the multiple first resource sets through ResourceSet configuration. The ResourceSet configuration may include, for example, a first resource set identifier (ResourceGroupID), resource type, usage, power control related parameters, etc. The ResourceGroup configuration may further include a ResourceIDlist, which lists the identifiers of all resources included in the first resource set (ResourceGroup), i.e., ResourceIDs.

[0345] The second resource configuration information further indicates each resource in each first resource set through a resource configuration. Each resource corresponds to a resource configuration, where the resource configuration includes, for example, a resource identifier (Resource ID), the number of resource ports, combing and cyclic shift configuration, time domain resource configuration, frequency domain resource configuration, precoding configuration, etc. In this embodiment of the present application, the number of resource ports is defined as the number of second antenna ports.

[0346] The second resource configuration information needs to indicate the correspondence between each resource and the first resource group it belongs to. For example, if Resource#1 corresponds to ResourceGroup#2, the second resource configuration information includes the correspondence between Resource#1 and ResourceGroup#2.

[0347] In one embodiment, the second resource configuration information includes a first resource set identifier corresponding to each resource in the first resource set.

[0348] The second resource configuration information may represent the correspondence between the first resource set and each resource in the first resource set through ResourceGroup configuration or Resource configuration.

[0349] Optionally, the first resource set identifier corresponding to each resource in the first resource set is configured in the ResourceSet configuration. For example, a ResourceGroupID can be marked after each ResourceID listed in the ResourceIDlist included in the ResourceSet configuration. The ResourceGroupID is the ID of the first resource set described by the Resource indicated by the ResourceID.

[0350] Optionally, the first resource set identifier corresponding to each resource in the first resource set is configured in the Resource configuration, wherein, for a certain Resource, its Resource configuration includes ResourceID. In an embodiment of the present application, a ResourceGroupID may be marked after the ResourceID, and the ResourceGroupID is the ID of the first resource set described by the Resource indicated by the ResourceID.

[0351] In S403, the network device sends second resource configuration information to the terminal.

[0352] In S404, the terminal performs resource configuration according to the second resource configuration information.

[0353] To be consistent with the behavior of the terminal, the network device may also configure the terminal according to the description in S404.

[0354] The process of resource configuration by the network device (terminal) includes: calculating the cyclic shift and the frequency domain starting position of the antenna port.

[0355] For example, a first resource set includes two resources, wherein the number of second antenna ports corresponding to one resource is 1 port, and the number of second antenna ports corresponding to the other resource is 2 ports.

[0356] For the first resource, determine the antenna port identifier corresponding to the resource, refer to the calculation formula disclosed above, and calculate the cyclic shift of the antenna port and the frequency domain starting position corresponding to the resource based on the antenna port identifier. This application will not go into details.

[0357] For the second resource, determine the two antenna port identifiers corresponding to the resource, for example, {1000, 1001}, then refer to the calculation formula disclosed above to calculate the cyclic shift and frequency domain starting position corresponding to the two antenna ports respectively, which will not be repeated in this application.

[0358] The solution provided in the embodiment of the present application supports combined transmission of the number of ports corresponding to different resources, and by configuring the same spatial information and power control parameters for different resources, it ensures that sending signals through different resources achieves the same result as sending signals through the same resource.

[0359] Based on the above embodiments, in the embodiments of the present application, after the network device (terminal) completes resource configuration, the network device can perform downlink scheduling. As shown in Figure 9, Figure 9 shows a schematic interaction diagram of a downlink scheduling method 900 provided in an embodiment of the present application. Each step of the method 900 is described in detail below.

[0360] In S901, the network device sends downlink control information to the terminal, where the downlink control information carries a resource indication field or a resource set indication field.

[0361] In S902, the terminal configures PUSCH transmission according to the target first resource set indicated by the resource indication field or the resource set indication field.

[0362] The bit width of the resource indication field or the bit width of the resource set indication field corresponds to the number of first resource sets, and the target first resource set indicated by the resource indication field or the resource set indication field is used to configure PUSCH transmission.

[0363] In the embodiment of the present application, the bit width of the resource indication field refers to the number of bits occupied by the resource indication, and the bit width of the resource set indication field refers to the number of bits occupied by the resource set indication.

[0364] In one implementation, a resource indication field or a resource set indication field may be configured through high-level parameters to indicate the number of combined ports. When the high-level parameters configure the indication, the bit width of the resource indication field or the bit width of the resource set indication field is related to the number of ResourceGroups under a ResourceSet.

[0365] In this embodiment of the present application, the downlink control information only needs to carry one of the resource indication field and the resource set indication field. The resource indication field and the resource set indication field have the same function, which is used to indicate the target first resource set. The target first resource set is one of multiple first resource sets. The terminal can use the antenna port combination corresponding to the multiple resources in the target first resource set for PUSCH transmission.

[0366] In an embodiment of the present application, a network device sends a DCI to a terminal, the DCI carrying a resource indication field or a resource set indication field, and the terminal performs an uplink transmission according to the target first resource set indicated by the resource indication field or the resource set indication field. In an embodiment of the present application, when performing PUSCH transmission, the terminal configures the data carried on the PUSCH according to the relevant parameter information corresponding to the target first resource set.

[0367] At the same time, in an embodiment of the present application, during PUSCH transmission, the terminal linearly scales the PUSCH non-zero power according to the sum of the numbers of second antenna ports corresponding to the resources in the target first resource set.

[0368] For example, the target first resource set includes 2 resources, and the number of second antenna ports corresponding to each resource is 2 ports and 4 ports. In this case, when the terminal performs PUSCH transmission, it uses 2 ports + 4 ports = 6 ports to linearly scale the PUSCH non-zero power.

[0369] Optionally, during PUSCH transmission, the terminal linearly scales the PUSCH non-zero power according to a ratio of the number of antenna ports for PUSCH transmission to the number of combined ports corresponding to the target first resource set.

[0370] In an embodiment of the present application, not all antenna ports corresponding to the first resource set are necessarily used for PUSCH transmission. In this case, the terminal linearly scales the number of antenna ports with non-zero power for PUSCH transmission within a ResourceGroup to the number of combined ports corresponding to the ResourceGroup. The number of combined ports is the sum of the number of second antenna ports corresponding to all resources in the ResourceGroup.

[0371] Please refer to Figure 10, which shows a schematic interactive diagram of a method 1000 for configuring resources provided in an embodiment of the present application. Each step of the method 1000 will be described in detail below.

[0372] In S1002, the network device sends first resource configuration information to the terminal.

[0373] The first resource configuration information indicates at least one resource and a first number of antenna ports corresponding to the resource. The first number of antenna ports is equal to the number of antenna ports of the terminal, and the first number of antenna ports is determined according to the port capability reported by the terminal.

[0374] Optionally, the at least one resource is a sounding reference signal SRS resource. Optionally, the at least one resource may also be, for example, a PUSCH resource, a PDSCH resource, a PUCCH resource, a PDCCH resource, etc. This application does not limit the specific type of the resource.

[0375] In this embodiment of the present application, the number of first antenna ports corresponding to each resource is determined based on the terminal's port capabilities. When configuring resources for different terminals, it is necessary to obtain the port capabilities of each terminal. Port capabilities can be indicated by the number of logical transmit antennas supported by the terminal. The terminal can proactively report port capabilities to the network device, or it can respond to a request from the network device to report port capabilities to the network device. Therefore, method 1000 may further include S1001 before S1002.

[0376] In S1001 , the terminal reports port capabilities to the network device.

[0377] For example, if a terminal supports three transmit antennas (hereinafter referred to as transmit antennas), the port capability reported by the terminal to the network device includes information about three antenna ports, indicating that the terminal needs to configure three antenna ports. In this case, the network device configures three antenna ports for each resource corresponding to the first antenna port number for the terminal.

[0378] For another example, if a terminal supports four transmit antennas, the port capability reported by the terminal to the network device includes information about four antenna ports, which means that the terminal needs to configure four antenna ports. In this case, the network device configures four antenna ports for each resource corresponding to the first antenna port number for the terminal.

[0379] For another example, if a terminal supports 7 transmit antennas, the port capability reported by the terminal to the network device includes 7 antenna port information, which means that the number of antenna ports required to be configured by the terminal is 7 ports. In this case, the first antenna port number corresponding to each resource configured by the network device for the terminal is 7 ports.

[0380] As can be seen from the previous content, the existing protocol specifies that the number of antenna ports corresponding to each resource ranges from (1, 2, 4). Obviously, the existing range of antenna port numbers does not include configurations such as 3 ports and 7 ports. Therefore, the embodiments of this application are essentially modifications to the existing protocol, adding 3 ports and / or 7 ports to the range of antenna ports corresponding to each resource specified in the existing protocol. It should be noted that 3 ports and 7 ports are only illustrative examples and do not constitute a limit on the number of antenna ports newly added in this solution.

[0381] Optionally, in an embodiment of the present application, the network device may enable the antenna ports of the terminal. In other words, the network device independently determines the number of antenna ports that the terminal needs to enable. In this case, the number of antenna ports of the terminal in the embodiment of the present application refers to the number of antenna ports enabled by the network device.

[0382] In one implementation, the network device directly sends enabling information to the terminal without requiring the terminal to report its port capabilities. For example, if the terminal supports 8T, the network device does not consider the terminal's port capabilities and directly enables the terminal's antenna port to be 5T. Accordingly, in this solution, the terminal has 5 antenna ports. Therefore, the network device configures each resource for the terminal with a first antenna port number of 5 ports.

[0383] In another implementation, after receiving the terminal's reported port capabilities, the network device determines a smaller value than the terminal's reported port capabilities as the number of antenna ports enabled by the terminal. For example, the terminal's reported port capabilities support 8T, but the network device determines, based on various factors, that the terminal's antenna ports are 5T. Accordingly, in this solution, the terminal's antenna ports are 5. The network device then configures each resource for the terminal with a first antenna port number of 5 ports.

[0384] In one implementation, by adding the number of configured ports for resources to the existing protocol, the value range of the number of antenna ports corresponding to each resource is (1, 2, 4, M), where M is an integer equal to or greater than 3 and M is a variable. In the embodiment of the present application, when a value that is compatible with the port capability of the terminal cannot be found in the existing range of values ​​for the number of antenna ports, such as (1, 2, 4), the network device can independently determine the value of M based on the port capability of the terminal and use the value of M as the first number of antenna ports corresponding to the resource configured for the terminal.

[0385] In another implementation, increasing the number of configured ports of resources in the existing protocol means expanding the value range of the number of antenna ports corresponding to each resource specified in the existing protocol, for example, expanding the value range from (1, 2, 4) to (1, 2, 3, 4).

[0386] In the embodiments of the present application, when the number of antenna ports required by a terminal's port capabilities conflicts with existing protocols, the uplink transmission requirement is met by increasing the number of ports configured in the resource. This minimizes changes to existing protocols and allows for flexible adaptation to terminals with various antenna architectures. For example, if a terminal has a three-antenna architecture, by adding a three-port configuration to the number of ports configured in the resource, each resource can be directly configured with three ports. Another example is if a terminal has a five-antenna architecture, by adding a five-port configuration to the number of ports configured in the resource, each resource can be directly configured with five ports.

[0387] In an embodiment of the present application, optionally, the first resource configuration information indicates the at least one resource (Resource) through a Resource configuration, where the Resource configuration includes, for example, a Resource ID, a number of Resource ports, combing and cyclic shift configuration, time domain resource configuration, frequency domain resource configuration, precoding configuration, etc. In an embodiment of the present application, the number of Resource ports is defined as the number of first antenna ports. Optionally, the number of first antenna ports corresponding to the multiple Resources is the same.

[0388] Optionally, the first resource configuration information indicates the at least one resource through a two-level configuration of a resource set (ResourceSet) and a resource (Resource). The network device can configure one or more ResourceSets for the terminal; each ResourceSet can be configured with one or more Resources. The ResourceSet configuration includes, for example, ResourceSetID, Resource type, usage, power control related parameters, etc. Resource configuration includes, for example, ResourceID, number of Resource ports, combing and cyclic shift configuration, time domain resource configuration, frequency domain resource configuration, precoding configuration, etc. In the embodiment of the present application, the number of Resource ports is defined as the number of first antenna ports.

[0389] In the embodiment of the present application, the number of configurable Resources in each ResourceSet is related to the port capabilities supported by the terminal, and the number of first antenna ports corresponding to multiple Resources under a ResourceSet is the same.

[0390] Optionally, the Resource configurations of multiple Resources under a ResourceSet may be different or partially the same.

[0391] Optionally, the number of Resources included in different ResourceSets may be the same, partially the same, or completely different.

[0392] Optionally, the ResourceSet configurations of different ResourceSets are different.

[0393] It should be noted that the first resource configuration information may be sent via downlink control signaling or higher layer signaling.

[0394] In S1003, the terminal performs resource configuration according to the first resource configuration information.

[0395] In one embodiment, the process of performing resource configuration on the terminal includes: respectively calculating cyclic shifts corresponding to the corresponding number of antenna ports indicated by the first number of antenna ports, wherein the cyclic shifts are used to generate a signal sequence to be transmitted.

[0396] For example, at least one resource indicated by the first resource configuration information is an SRS resource, the number of antenna ports of the terminal is 3, and the number of first antenna ports corresponding to each SRS resource is 3ports. Combined with the above content, it can be seen that the antenna port identifier can be expressed as {1000, 1001, 1002}, and then the cyclic shift corresponding to each antenna port {1000, 1001, 1002} is calculated respectively. At this time

[0397] Among them, the antenna port p i The cyclic shift α i The calculation formula is as follows:

[0398] in,

[0399] In another embodiment, the process of resource configuration of the terminal includes: calculating the frequency domain starting position of each antenna port of each resource according to the corresponding number of antenna ports indicated by the first antenna port number corresponding to each resource and the number of antenna ports of the terminal.

[0400] For example, the first antenna port number indicates a corresponding number of antenna ports {1000, 1001, 1002}. For each resource, the frequency domain starting positions corresponding to the three antenna ports of each resource are calculated.

[0401] Among them, the antenna port p of a certain resource i The starting position of the frequency domain The calculation formula is as follows:

[0402] in,

[0403] Among them, combined with the content disclosed above, it can be known that the frequency domain starting position is calculated using different formulas for odd-numbered antenna port groups or even-numbered antenna port groups. Therefore, antenna ports {1000, 1002} are respectively assigned to the same frequency domain starting position. It is only necessary to calculate the frequency domain starting position of antenna port {1002} to obtain the frequency domain starting position of antenna port {1000}. Among them, the frequency domain starting position of antenna port {1002} can be calculated by referring to the above formula. The corresponding content.

[0404] In addition, in the embodiment of the present application, the frequency domain starting position of the antenna port {1001} is calculated When the parameters involved It can be calculated using the following formula:

[0405] It should be noted that, in order to be consistent with the behavior of the terminal, the network device may also calculate the cyclic shift and the frequency domain starting position of the antenna port according to the description in S403.

[0406] This solution only slightly changes existing resources, increasing the number of configured ports for one resource. It also makes minimal protocol changes while enabling three-port transmission. Corresponding adjustments are made to the cyclic shift of the corresponding antenna ports and the calculation of the frequency domain starting position.

[0407] The following is a detailed description of 400 scenarios of the method for configuring resources provided in an embodiment of the present application.

[0408] In scenario #1, for an uplink 3T antenna port architecture, an example of using a 1T+2T combined port transmission is as follows:

[0409] The terminal is configured to multiple SRS ResourceSets through network devices. Each SRS ResourceSet is configured with multiple ResourceGroups. Each ResourceGroup is configured with two Resources. The number of second antenna ports corresponding to one Resource is 1, and the number of second antenna ports corresponding to the other Resource is 2. The number of second antenna ports is configured in nrofSRS-Ports. The correspondence between ResourceGroup and Resource, and the correspondence between ResourceGroup and SRS ResourceSet can be included in the ResourceSet configuration or in the Resource configuration.

[0410] It should be noted that in the embodiment of the present application, 1T / 2T / 4T / 3T are all logical antenna ports.

[0411] Airspace information:

[0412] For SRS spatial relationship information (SRS-SpatialRelationInfo), the two Resources of each ResourceGroup are configured with the same servingCellID and referenceSignal; among which, the referenceSignal includes the synchronization signal block (SSB) index, the channel state information reference signal (CSI-RS) index, the sounding reference signal (SRS) resource identifier, and the uplink bandwidth part (BWP).

[0413] Resource indication overhead and mapping:

[0414] The bit width of the resource indication field or the resource set indication field is related to the number of ResourceGroups under a ResourceSet. For ease of description, the following example will be based on the resource indication field SRI. In this application, the number of bits N in calculating the number of bits of SRI is SRS In this solution, it is defined as the number of ResourceGroups.

[0415] When the network device enables the terminal to perform 3Tx transmission or the terminal reports its support for 3Tx transmission through capabilities, SRI is used to indicate the resources corresponding to PUSCH transmission. The bit width of SRI is related to the number of ResourceGroups under a ResourceSet.

[0416] The mapping relationship of the SRI bit field is exemplified as follows, where the first index value of the SRI bit field is associated with the first ResourceGroup, the second index value of the SRI bit field is associated with the second ResourceGroup, and so on:

[0417] Furthermore, the antenna port used by the terminal when transmitting the SRS Resource in the ResourceGroup indicated by the SRI is used for PUSCH transmission.

[0418] Power control parameters:

[0419] calculate in, is the PUSCH non-zero power P PUSCH,b,f,c (i,j,q d ,l), b activated uplink BWP, f carrier, c serving cell, i PUSCH transmission time, j parameter set configuration index, q d Reference signal table below, l PUSCH power control adaptation state subscript.

[0420] When PUSCH-Config is not configured with fullpowerMode1, fullpowerMode2, or fullpower, and the usage of SRS-ResourceSet is 'codebook', for PUSCH non-zero transmit power, the terminal linearly scales the non-zero transmit power of PUSCH by the ratio of the number of antenna ports in a ResourceGroup with non-zero PUSCH transmission power to the number of combined ports corresponding to the ResourceGroup. The number of combined ports is the sum of the number of second antenna ports corresponding to all resources in the ResourceGroup.

[0421] The second resource set ResourceSet configures power control parameters for the multiple first resource sets ResourceGroup it includes. The power control parameters of each resource in a ResourceGroup are the same. The power control parameters include: configuration parameters for path loss compensation (alpha), target received power (p0), path loss reference signal (pathlossReferenceRS), and SRS power control adaptation state (SRS-powercontroladjustmentstates).

[0422] Furthermore, the terminal performs PUSCH transmission using the power control parameters when transmitting the SRS Resource in the ResourceGroup indicated by the SRI.

[0423] In this embodiment, SRS Resources for different antenna ports are combined to create an equivalent number of new antenna ports. This is achieved by adding a ResourceGroup level between the SRS ResourceSet and the Resource. This level can be included in either the ResourceSet configuration or the ResourceGroup configuration. This level is used to group and configure resources configured with different numbers of ports, thereby achieving the purpose of combining ports.

[0424] In scenario #2, for an uplink 3T antenna port architecture, an example of using a 1T+2T combined port transmission is as follows:

[0425] The terminal is configured with two SRS ResourceSets through network devices. ResourceSet 1 has three resources, each with one SRS port, and belongs to Group 1, Group 2, and Group 3 respectively. ResourceSet 2 also has three resources, each with two SRS ports, and belongs to Group 1, Group 2, and Group 3 respectively.

[0426] The three resources in a group are configured with the same airspace information and power control parameters.

[0427] Airspace information:

[0428] For SRS spatial relationship information (SRS-SpatialRelationInfo), the resources in the group are configured with the same servingCellID and referenceSignal at the first level. The referenceSignal includes the synchronization signal block index, channel state information reference signal index, SRS resource identifier, and uplink bandwidth part (BWP). The resources in the group use the same spatial filter.

[0429] Resource indication overhead and mapping:

[0430] The bit width of the resource indication field or the resource set indication field is related to the number of groups. For ease of description, the following example will be based on the resource indication field SRI. In this application, the number of SRI bits is calculated as N. SRS In this solution, it is defined as the number of groups.

[0431] When the network device enables the terminal to perform 3Tx transmission or the terminal reports its support for 3Tx transmission through capabilities, SRI is used to indicate the resources for PUSCH transmission. The bit width of SRI is related to the number of groups.

[0432] The mapping relationship of the SRI bit field is exemplified as follows: the first index value of the SRI bit field is associated with the first group, the second index value of the SRI bit field is associated with the second group, and so on:

[0433] Furthermore, the antenna port used by the terminal in each Group indicated by the SRI is used for PUSCH transmission.

[0434] Power control parameters:

[0435] calculate in, is the PUSCH non-zero power P PUSCH,b,f,c (i,j,q d ,l), b activated uplink BWP, f carrier, c serving cell, i PUSCH transmission time, j parameter set configuration index, q d Reference signal table below, l PUSCH power control adaptation state subscript.

[0436] When PUSCH-Config is not configured with fullpowerMode1, fullpowerMode2, or fullpower, and the usage of SRS-ResourceSet is 'codebook', for PUSCH non-zero transmit power, the terminal linearly scales the non-zero transmit power of PUSCH by the ratio of the number of antenna ports in a ResourceGroup with non-zero PUSCH transmission power to the number of combined ports corresponding to the ResourceGroup. The number of combined ports is the sum of the number of second antenna ports corresponding to all resources in the ResourceGroup.

[0437] Among them, the same power control parameters are configured in the Group, that is, different power control parameter groups are configured for multiple Groups under one ResourceSet, and there is a corresponding relationship with the configuration of another or more ResourceSets. The power control parameters include: configuration parameters for path loss compensation (alpha), target received power (p0), path loss reference signal (pathlossReferenceRS), and SRS power control adaptation state (srs-powercontroladjustmentstates).

[0438] Furthermore, the terminal performs PUSCH transmission while transmitting the power control parameters of the SRS Resource in the Group indicated by the SRI.

[0439] In this embodiment, the SRS Resources in different SRS ResourceSets are combined according to the Group tag to achieve the purpose of forming an equivalent number of new antenna ports. A Group-level tag is added to each SRS Resource. Certain unified configurations are required under the same Group tag, which means that each Resource in the SRS ResourceSet will have different parameter configurations.

[0440] In scenario #3, for an uplink 3T antenna port architecture, an example of using a 1T+2T combined port transmission is as follows:

[0441] The terminal is configured to multiple SRS ResourceSets through network devices. Each SRS ResourceSet is configured with two resources. One resource is configured with one SRS port, and the other resource is configured with two SRS ports. The number of ports is configured in nrofSRS-Ports.

[0442] Airspace information:

[0443] For SRS spatial relationship information (SRS-SpatialRelationInfo), the two Resources of each ResourceGroup are configured with the same servingCellID and referenceSignal; among which, the referenceSignal includes the synchronization signal block (SSB) index, the channel state information reference signal (CSI-RS) index, the sounding reference signal (SRS) resource identifier, and the uplink bandwidth part (BWP).

[0444] Resource indication overhead and mapping:

[0445] The bit width of the resource indication field or the bit width of the resource set indication field is related to the number of resources. For ease of description, the SRS resource set indication field SRSI is used as an example below.

[0446] When the network device enables the terminal to perform 3Tx transmission or the terminal reports its support for 3Tx transmission through capabilities, SRSI is used to indicate the resources for PUSCH transmission. The bit width of SRSI is related to the number of ResourceSets. In this case, there is no need to configure SRI to indicate the resources for PUSCH transmission.

[0447] The following is an example of the mapping relationship of the SRSI bit field: the first index value of the SRSI bit field is associated with the first ResourceSet, the second index value of the SRSI bit field is associated with the second ResourceSet, and so on:

[0448] Furthermore, the antenna port used by the terminal when transmitting the SRS Resource in the ResourceSet indicated by the SRSI is used for PUSCH transmission.

[0449] Power control parameters:

[0450] calculate in, is the PUSCH non-zero power P PUSCH,b,f,c (i,j,q d ,l), b activated uplink BWP, f carrier, c serving cell, i PUSCH transmission time, j parameter set configuration index, q d Reference signal table below, l PUSCH power control adaptation state subscript.

[0451] When PUSCH-Config is not configured with fullpowerMode1, fullpowerMode2, or fullpower, and the usage of SRS-ResourceSet is 'codebook', for PUSCH non-zero transmit power, the terminal linearly scales the PUSCH non-zero transmit power by the ratio of the number of antenna ports for PUSCH non-zero power transmission in a ResourceGroup to the number of combined ports corresponding to the ResourceGroup. The number of combined ports is the sum of the number of second antenna ports corresponding to all resources in the ResourceGroup.

[0452] Among them, each ResourceSet configures the same power control parameters for each Resource it includes. The power control parameters include: configuration parameters for path loss compensation (alpha), target received power (p0), path loss reference signal (pathlossReferenceRS), and SRS power control adaptation state (srs-powercontroladjustmentstates).

[0453] Furthermore, the terminal performs PUSCH transmission using the power control parameters used when transmitting the SRS Resource in the ResourceSet indicated by the SRSI.

[0454] In this embodiment, different SRS Resources within the same SRS ResourceSet are combined to create an equivalent number of new antenna ports. Each SRS ResourceSet corresponds to a specific antenna port combination, and each Resource in the ResourceSet is configured with a different antenna port. Other parameters are configured uniformly. In this case, the SRSI is used as the resource indicator, rather than the SRI.
