[0002] In the field of wireless communications, in order to ensure that a terminal device can better receive and demodulate signals, the terminal device usually needs to obtain a quasi co-location (QCL) relationship of an antenna port so as to demodulate data according to the QCL relationship. In the existing Long Term Evolution (LTE) and New Radio (NR) protocols, it is specified that for different reference signal types, the acquisition of QCL reference types has the following situations: for example, through Radio Resource Control (RRC) configuration, such as periodic Channel State Information-Reference Signals (CSI-RS) / Tracking Reference Signal (TRS); through RRC configuration, activated by the Media Access Control-Control Element (MAC-CE), such as the periodic CSI-RS / TRS indicated by MAC-CE for activation and deactivation, or the demodulation reference signal (DMRS) of the Physical Downlink Control Channel (PDCCH) for activation and deactivation; through RRC configuration, activated by MAC-CE and indicated by downlink control information (DCI), such as aperiodic CSI-RS / TRS, or Physical Downlink Shared Channel (PDCCH) for activation and deactivation. Channel, PDSCH)’s DMRS.

[0003] The existing MAC-CE has two types: PDCCH and PDSCH. Taking the NR R16 standard as an example, the content of MAC-CE is as follows Figure 1 , 2, 3. However, currently, it is assumed that the terminal device performs demodulation optimization according to the QCL relationship. Before receiving further commands from the network device, the terminal device assumes that the DMRS of PDCCH and PDSCH have a QCL relationship with the synchronization signal (SS) / physical broadcast channel (PBCH) of the initial access. If the network device performs certain operations (for example, pre-compensation) and the terminal device cannot be informed, it will cause the network device and the terminal device to perform QCL operations at the same time, resulting in a decrease in demodulation performance or demodulation errors.

[0038] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0039] In addition, in the embodiments of the present application, words such as "optionally" or "exemplarily" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "optionally" or "exemplarily" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "optionally" or "exemplarily" is intended to present related concepts in a specific way.

[0040] Figure 4 is a flow chart of an information indication method provided by an embodiment of the present application, such as Figure 4 As shown, the method may include the following steps:

[0041] S401. The first communication node generates a control command.

[0042] Exemplarily, the first communication node may be a network device on the network side, such as a base station, etc. The control command may carry control information, or the control command may carry control information and pre-compensation parameter information, wherein the control information may be used to indicate whether the first communication node pre-compensates the first parameter of the PDCCH, PDSCH, and CSI-RS according to the configured QCL relationship, and the pre-compensation parameter information is used to indicate the first parameter.

[0043] Optionally, the control command may include at least one of a media access control element (MAC CE), a PDCCH DCI, and an RRC message, and the first parameter may include at least one of a Doppler shift, an average delay, a Doppler spread, a delay spread, and a spatial Rx parameter.

[0044] Optionally, in an embodiment of the present application, the QCL relationship can be configured through an RRC message. When the control command is an RRC message, that is, when the RRC message indicates whether the first communication node pre-compensates the first parameter, it can be indicated through an RRC message, that is, the RRC message carries the configured QCL relationship, and can also indicate whether the first communication node pre-compensates the first parameter.

[0045] S402: The first communication node sends a control command to the second communication node.

[0046] The second communication node in this step may be a communication node such as a user equipment or a terminal.

[0047] In an embodiment of the present application, after the first communication node generates a control command, the control command is sent to the second communication node, wherein the control command carries control information, or control information and pre-compensation parameter information, the pre-compensation parameter information is used to indicate the first parameter, and the control information is used to indicate whether the first communication node pre-compensates the first parameter of at least one of PDCCH, PDSCH, and CSI-RS according to the configured QCL relationship. In this way, the second communication node can determine whether to perform subsequent compensation operations according to the content indicated in the control command.

[0048] In one example, when the control command includes a MAC CE, the MAC CE may be used to indicate whether the first communication node pre-compensates the first parameter and to indicate whether the second communication node enables or disables the first parameter compensation operation between the first channel and the first signal. The MAC CE may be identified by a MAC subheader identified by a logical channel.

[0049] In one example, the MAC CE may include one or more 1-bit first parameter pre-compensation indication fields, which are used to indicate that the first communication node has not performed first parameter pre-compensation and to indicate that the second communication node enables the first parameter compensation operation between the first channel and the first signal, or the first parameter pre-compensation indication field is used to indicate that the first communication node has performed first parameter pre-compensation and to indicate that the second communication node disables the first parameter compensation operation between the first channel and the first signal.

[0050] For example, a first parameter pre-compensation indication field of "1" can be used to indicate that the first communication node has not performed the first parameter pre-compensation and instruct the second communication node to enable the first parameter compensation operation between the first channel and the first signal, and a first parameter pre-compensation indication field of "0" can be used to indicate that the first communication node performs the first parameter pre-compensation and instructs the second communication node to disable the first parameter compensation operation between the first channel and the first signal. Alternatively, a first parameter pre-compensation indication field of "0" can be used to indicate that the first communication node has not performed the first parameter pre-compensation and instructs the second communication node to enable the first parameter compensation operation between the first channel and the first signal, and a first parameter pre-compensation indication field of "1" can be used to indicate that the first communication node performs QCL pre-compensation and instructs the second communication node to disable the first parameter compensation operation between the first channel and the first signal.

[0051] In one example, when the control information includes PDCCH DCI, the PDCCH DCI is a 1-bit first parameter pre-compensation indication field, and the first parameter pre-compensation indication field is used to indicate that the first communication node has not performed first parameter pre-compensation and to instruct the second communication node to enable the first parameter compensation operation between the first channel and the first signal, or the first parameter pre-compensation indication field is used to instruct the first communication node to perform first parameter pre-compensation and to instruct the second communication node to disable the first parameter compensation operation between the first channel and the first signal.

[0052] For example, a first parameter pre-compensation indication field of "1" can be used to indicate that the first communication node has not performed first parameter pre-compensation and instruct the second communication node to enable the first parameter compensation operation between the first channel and the first signal, and a first parameter pre-compensation indication field of "0" can be used to indicate that the first communication node performs first parameter pre-compensation and instructs the second communication node to disable the first parameter compensation operation between the first channel and the first signal. Alternatively, a first parameter pre-compensation indication field of "0" can be used to indicate that the first communication node has not performed first parameter pre-compensation and instructs the second communication node to enable the first parameter compensation operation between the first channel and the first signal, and a first parameter pre-compensation indication field of "1" can be used to indicate that the first communication node performs first parameter pre-compensation and instructs the second communication node to disable the first parameter compensation operation between the first channel and the first signal.

[0053] Optionally, the first parameter pre-compensation indication domain and the first parameter pre-compensation indication field may be designed to be "T" or "F" or other forms to perform different indications, which is not limited in the embodiments of the present application.

[0054] In one example, when the control information includes an RRC message, the RRC message may be used to indicate that the first communication node has not performed first parameter pre-compensation and to indicate that the second communication node enables the first parameter compensation operation between the first channel and the first signal, or, the RRC message is used to indicate that the first communication node has performed first parameter pre-compensation and to indicate that the second communication node disables the first parameter compensation operation between the first channel and the first signal.

[0055] For example, the "1" carried in the RRC message can be used to indicate that the first communication node has not performed the first parameter pre-compensation and instruct the second communication node to enable the first parameter compensation operation between the first channel and the first signal, and the "0" carried in the RRC message can be used to indicate that the first communication node has performed the first parameter pre-compensation and instruct the second communication node to disable the first parameter compensation operation between the first channel and the first signal. Alternatively, the "0" carried in the RRC message can be used to indicate that the first communication node has not performed the first parameter pre-compensation and instruct the second communication node to enable the first parameter compensation operation between the first channel and the first signal, and the "1" carried in the RRC message can be used to indicate that the first communication node has performed the first parameter pre-compensation and instruct the second communication node to disable the first parameter compensation operation between the first channel and the first signal.

[0056] Similarly, the RRC message may also carry information in different forms such as "T" and "F" to indicate whether the first communication node performs first parameter pre-compensation.

[0057] In an example, the first channel may include a PDCCH and / or a PDSCH;

[0058] The first signal includes SS / PBCH and / or TRS.

[0059] Optionally, the 1 bit instructing the second communication node to disable or enable the first parameter relationship between the first channel and the first signal may be a separate 1-bit command field, or may be multiplexed into a DCI field.

If the field is "1", the first parameter compensation operation between the first channel and the first signal is enabled, that is, one or more parameters of average delay, Doppler shift, delay extension, Doppler extension, and spatial reception parameters are used for PDSCH according to the configuration. If the field is "0", no first parameter compensation operation is enabled for PDSCH. Alternatively, if the field is "0", the QCL relationship between the first channel and the first signal is enabled, that is, one or more parameters of average delay, Doppler shift, delay extension, Doppler extension, and spatial reception parameters are used for PDSCH according to the configuration.

[0091] Fig.11 A flowchart of an information indication method provided in an embodiment of the present application, such as Figure 4 As shown, the method may include the following steps:

[0092] S1101. The second communication node receives a control command.

[0093] Exemplarily, the second communication node may be a terminal, a user equipment, etc. The control command may be a command sent by a first communication node (for example, a network device such as a base station), and the control command may carry control information, or control information and pre-compensation parameter information, the control information is used to indicate whether the first communication node pre-compensates the first parameter of the PDCCH, PDSCH, and CSI-RS according to the configured first parameter compensation operation, and the pre-compensation parameter information is used to indicate the first parameter.

[0094] Optionally, the control command may include at least one of MAC CE, PDCCH DCI, and RRC message. The first parameter may include at least one of Doppler shift, average delay, Doppler spread, delay spread, and spatial reception parameter.

[0095] S1102. The second communication node enables or disables a first parameter compensation operation between a first channel and a first signal according to a control command.

[0096] Exemplarily, the first channel may include a PDCCH and / or a PDSCH;

[0097] The first signal includes SS / PBCH and / or TRS.

[0098] That is, after the second communication node obtains the control command, it enables or disables the first parameter compensation operation between the first channel and the first signal according to the specific instructions in the control command.

[0099] An embodiment of the present application provides an information indication method, where a second communication node receives a control command and enables or disables a first parameter compensation operation between a first channel and a first signal according to the control command. In one example, in the case where the control command includes a MAC CE, one MAC CE may be for the operation of the PDCCH and the PDSCH QCL of a specific control resource set (CORESET) of a specific serving cell (serving cell) of the second communication node and a specific bandwidth part (Bandwidth Part, BWP), or, one MAC CE may be for the operation of the PDCCH QCL of a specific CORESET of a specific serving cell of the second communication node, or, one MAC CE may be for the operation of the PDSCH QCL of a specific BWP of a specific serving cell of the second communication node, or, one MAC CE may be for the operation of the PDCCH QCL of all CORESETs of a specific serving cell of the second communication node, or, one MAC CE may be for the operation of the PDSCH QCL of all BWPs of a specific serving cell of the second communication node, or, one MAC CE may be for the operation of the PDSCH QCL of all CORESETs of all serving cells of the second communication node, or, one MAC CE may be for the operation of the PDSCH QCL of all BWPs of all serving cells of the second communication node, or, one MAC CE can operate QCL of PDCCH of all CORESETs and PDSCH of all BWPs of all serving cells of the second communication node.

[0100] In an example, when the control command includes PDCCH DCI, a PDCCH DCI signaling may be directed to the operation of the PDSCH QCL of the second communication node-specific serving cell-specific BWP.

[0101] In an example, a specific implementation of the above step S1102 may be that the second communication node enables or disables the first parameter compensation operation between the first channel and the first signal according to the control information and the predefined parameter, where the predefined parameter is the first parameter carried in the control information;

[0102] Alternatively, the second communication node enables or disables the first parameter compensation operation between the first channel and the first signal according to the control information and the pre-compensation parameter information.

[0103] Further, in the case where the control command carries the control information and the predefined parameters, if the second communication node determines according to the control command that the first communication node has not pre-compensated the first parameter of at least one of the PDCCH, the PDSCH, and the CSI-RS, the second communication node enables a first parameter compensation operation between the first channel and the first signal;

[0104] Alternatively, if the second communication node determines, based on the control information, that the first communication node pre-compensates a first parameter of at least one of PDCCH, PDSCH, and CSI-RS, the second communication node disables the first parameter compensation operation between the first channel and the first signal.

[0105] In the case where the control command carries the control information and the pre-compensation parameter information, if the second communication node determines according to the control information that the first communication node has not pre-compensated the first parameter of at least one of the PDCCH, the PDSCH, and the CSI-RS, the second communication node enables the first parameter compensation operation between the first channel and the first signal according to the pre-compensation parameter information;

[0106] Alternatively, if the second communication node determines based on the control information that the first communication node pre-compensates the first parameter of at least one of PDCCH, PDSCH, and CSI-RS, the second communication node disables the first parameter compensation operation between the first channel and the first signal based on the pre-compensation parameter information.

[0107] Further, when the second communication node enables a first parameter compensation operation between the first channel and the first signal, the second communication node compensates for a first parameter of at least one of the PDCCH, the PDSCH, and the CSI-RS.

[0108] Alternatively, when the second communication node disables the first parameter compensation operation between the first channel and the first signal, the second communication node does not perform a compensation operation on a first parameter of at least one of PDCCH, PDSCH, and CSI-RS.

[0109] That is, the second communication node receives the control information sent by the first communication node, and the control information can indicate whether the first communication node pre-compensates the first parameter of at least one of PDCCH, PDSCH, and CSI-RS according to the configured quasi-co-site QCL relationship. If the control information indicates that the first communication node has not pre-compensated the first parameter of at least one of PDCCH, PDSCH, and CSI-RS, the second communication node enables the first parameter compensation operation between the first channel and the first signal, that is, the second communication node compensates for the first parameter of at least one of PDCCH, PDSCH, and CSI-RS. If the control information indicates that the first communication node pre-compensates the first parameter of at least one of PDCCH, PDSCH, and CSI-RS, the second communication node disables the first parameter compensation operation between the first channel and the first signal, that is, the second communication node does not perform compensation operation on the first parameter of at least one of PDCCH, PDSCH, and CSI-RS.

[0110] In one example, the second communication node not performing a compensation operation on the first parameter may include the second communication node not performing a compensation operation according to the first signal, but performing a compensation operation according to a demodulation reference signal (Demodulation Reference Signal, DMRS) of the second communication node.

[0111] In this way, by carrying relevant instruction content in the control information, the second communication node can perform subsequent compensation or non-compensation operations according to the specific instructions in the control information after receiving the control information.

[0112] Fig.12 An information indicating device provided in an embodiment of the present application, such as Fig.12 As shown, the device includes: a generating module 1201, a sending module 1202;

[0113] Wherein, the generating module is used to generate the control command;

[0114] A sending module, used for sending the control command to the second communication node;

[0115] Among them, the second communication node can be a terminal, a user equipment, etc., the control command can carry control information, or control information and pre-compensation parameter information, the control information can be used to indicate whether the device pre-compensates the first parameter of at least one of PDCCH, PDSCH, and CSI-RS according to the configured QCL relationship, and the pre-compensation parameter information is used to indicate the first parameter.

[0116] The control command may include at least one of MAC CE, PDCCH DCI, and RRC message, and the first parameter may include at least one of Doppler shift, average delay, Doppler spread, delay spread, and spatial reception parameter.
