[0113] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0114] The RF unit 101 can be used to send and receive information or receive signals during calls.

Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without altering the essence of the invention.

[0116] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like.

The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0118] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors.

As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described here.

Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using a finger, stylus, or any other suitable object or accessory on or near the touch panel 1071) and drive corresponding connected devices according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive and execute commands sent by the processor 110. And / or, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

[0121] Optionally, the touch panel 1071 may overlay the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the display panel 1061 based on the type of touch event. Although in FIG1 , the touch panel 1071 and the display panel 1061 are shown as two separate components to implement the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to implement the input and output functions of the mobile terminal, which is not limited to this specific embodiment.

[0276] Through the above technical solution, in the embodiment of the present application, in a PUSCH simultaneous transmission scenario based on multiple panels, the terminal device determines the PTRS scaling factor based on the first downlink information, thereby improving the accuracy of the PTRS scaling factor.

[0277] Seventh embodiment

[0278] This embodiment mainly focuses on the scenario of simultaneous PUSCH transmission on multiple panels, and elaborates on the method for determining SRS resources and / or PUSCH and PTRS port association under non-codebook transmission.

[0279] Optionally, when the transmission configuration parameter (txConfig) under the PUSCH configuration information element is set to non-codebook based transmission, a method for determining the association of SRS resources and / or PUSCH with the PTRS port based on at least one of the PTRS port index value parameter (ptrs-PortIndex), SRI resource indication parameter (sri-ResourceIndicator), second SRI resource indication parameter (sri-ResourceIndicator2), SRS resource indication field (SRS resource indicator) and second SRS resource indication field (Second SRS resource indicator) in the SRS configuration information element (SRS-Config).

[0280] For multi-panel-based PUSCH using spatial division multiplexing mode for simultaneous transmission, the number of PTRS ports is 2. If the PTRS port index value determined based on the SRS resource indication field and / or SRI resource indication parameter, and the value of the second SRS resource indication field and / or the second SRI resource indication parameter is the same, that is, there is only one PTRS port, which is inconsistent with the PTRS port number of 2 when multi-panel-based PUSCH uses spatial division multiplexing mode for simultaneous transmission.

[0281] To address the above issues, this embodiment proposes the following method for associating SRS resources and / or PUSCH with PTRS ports. Specifically, in a scenario where multiple panels of PUSCH are simultaneously transmitted using spatial division multiplexing, a method for determining the association of SRS resources and / or PUSCH with PTRS ports in non-codebook transmission is provided.

[0282] Optionally, the processing method of this embodiment includes:

[0283] Determine the association mode between SRS resources and / or PUSCH and PTRS ports based on non-codebook transmission.

[0284] Optionally, the SRS resources in each SRS resource set are configured with a same PTRS port index value;

[0285] Optionally, the SRS resources in each SRS resource set are configured with a same PTRS port index value and the PTRS port index values ​​configured for the SRS resources in two SRS resource sets are different;

[0286] Optionally, if the PTRS port index value corresponding to the first PUSCH is the same as the PTRS port index value corresponding to the second PUSCH, the PTRS port corresponding to the PTRS port index value is used as the PTRS port corresponding to the first PUSCH.

[0287] Optionally, if the PTRS port index value corresponding to the first PUSCH and the PTRS port index value corresponding to the second PUSCH are the same, the PTRS port corresponding to the PTRS port index value is used as the PTRS port corresponding to the first PUSCH and the PTRS port corresponding to the second PUSCH.

[0288] Optionally, if the PTRS port index value corresponding to the first PUSCH is the same as the PTRS port index value corresponding to the second PUSCH, the PTRS port corresponding to the PTRS port index value is used as the PTRS port corresponding to the first PUSCH, and the remaining PTRS port is used as the PTRS port corresponding to the second PUSCH.

[0289] Optionally, for the PUSCH simultaneous transmission scenario of multiple panels in the existing protocol, if based on non-codebook transmission, if the PTRS ports determined based on the first SRI and the second SRI are the same, it is inconsistent with the PTRS port number of 2 when based on SDM mode transmission.

[0290] Optionally, for a scenario where PUSCHs are transmitted simultaneously on multiple panels, a method for associating SRS resources and / or PUSCHs with PTRS ports under non-codebook transmission is determined, and a processing method is proposed, comprising the steps of:

[0291] The network device sends the second downlink information, so that the terminal device determines, based on the second downlink information, an association mode between SRS resources and / or PUSCH and PTRS ports under non-codebook transmission;

[0292] The terminal device determines, based on the second downlink information, an association method of SRS resources and / or PUSCH and PTRS ports based on non-codebook transmission.

[0293] Optionally, the second downlink information includes radio resource control and / or downlink control information.

[0294] The following describes in detail the implementation of a method for associating SRS resources and / or PUSCH with PTRS ports in a scenario where PUSCH is transmitted simultaneously using a spatial division multiplexing mode based on multiple panels. The processing method of this embodiment includes:

[0295] Step 1: The terminal device receives second downlink information, where the second downlink information includes radio resource control and / or downlink control information. Optionally, the radio resource control includes at least one of a PTRS port index value parameter (ptrs-PortIndex) under an SRS resource information element (SRS-Resource), an SRI resource indication parameter (sri-ResourceIndicator) and a second SRI resource indication parameter (sri-ResourceIndicator2) under an RRC-configured uplink grant information element (rrc-ConfiguredUplinkGrant); the downlink control information includes at least one of an SRS resource indication field (SRS resource indicator), a second SRS resource indication field (Second SRS resource indicator), a PTRS-DMRS association field (PTRS-DMRS association), and an antenna port field (Antenna ports);

[0296] Step 2: Determine the SRS resource from the first SRS resource set based on the value of the SRS resource indication field included in the downlink control information or the SRI resource indication parameter included in the radio resource control, and determine the PTRS port index value corresponding to the first PUSCH according to the value of the PTRS port index value parameter (ptrs-PortIndex) in the SRS resource; determine the SRS resource from the second SRS resource set based on the value of the second SRS resource indication field included in the downlink control information or the second SRI resource indication parameter included in the radio resource control, and determine the PTRS port index value corresponding to the second PUSCH according to the value of the PTRS port index value parameter in the SRS resource;

[0297] Step 3: Based on the SRS resource indication field or the SRI resource indication parameter, and / or the SRS resource indicated by the value of the second SRS resource indication field or the second SRI resource indication parameter, the DMRS port indicated by the value of the antenna port field (Antennaports), and the mapping relationship between the PUSCH layer included in the first PUSCH and / or the PUSCH layer included in the second PUSCH, determine the DMRS port or port set associated with the PTRS port corresponding to the first PUSCH and the DMRS port or port set associated with the PTRS port corresponding to the second PUSCH;

[0298] Step 4: Determine the DMRS port associated with the PTRS port corresponding to the first PUSCH and the DMRS port associated with the PTRS port corresponding to the second PUSCH based on the value of the PTRS-DMRS association field (PTRS-DMRS association).

[0299] Optionally, for step 2: in a multi-panel based PUSCH simultaneous transmission scenario, when the usage parameter (usage) in the first SRS resource set and the second SRS resource set is set to non-codebook, the PTRS port index value corresponding to the first PUSCH is determined from the first SRS resource set based on the value of the SRS resource indication field or the SRI resource indication parameter, thereby determining the number of PTRS ports corresponding to the first PUSCH; based on the value of the second SRS resource indication field or the second SRI resource indication parameter, the PTRS port index value corresponding to the second PUSCH is determined from the second SRS resource set, thereby determining the number of PTRS ports corresponding to the second PUSCH. In a multi-panel based PUSCH simultaneous transmission scenario, if the value of the PTRS maximum port number parameter (maxNrofPorts) is 2, the number of PTRS ports is 2, and therefore, the number of PTRS ports corresponding to the first PUSCH and the number of PTRS ports corresponding to the second PUSCH are both 1.
