[0029] To enable those skilled in the art to better understand the embodiments of this application, the following description is provided first.

[0030] Quasi-co-location refers to the ability to infer the large-scale parameters of the channel experienced by a symbol at one antenna port from the channel experienced by a symbol at another antenna port. These large-scale parameters may include delay spread, average delay, Doppler spread, Doppler shift, average gain, and spatial Rx parameter, among others.

[0031] The network configures quasi-co-location information through the Transmission Configuration Indicator (TCI). The quasi-co-location information includes the QCL-type and the specific reference signal. When transmitting signals or channels, users can obtain the corresponding large-scale parameters based on the QCL-type and the specific reference signal in the TCI.

[0032] In related technologies, QCL relationships are divided into four types:

[0033] QCL type A: {Doppler shift, Doppler spread, average delay, delay spread};

[0034] QCL type B: {Doppler shift, Doppler spread};

[0035] QCL type C: {Doppler shift, average delay};

[0036] QCL type D:{Spatial Rx parameter}.

[0037] The aforementioned QCL type D, or beam reference, is currently under consideration for a unified architecture for uplink and downlink beams. QCL type D may not only be a spatial receiving parameter, but also a spatial transmission parameter or a spatial transmit / receive parameter, i.e., it includes spatial receiving parameters and / or spatial transmit parameters (Spatial Tx parameter).

[0038] The method for obtaining quasi-co-location information provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0039] like Figure 2 As shown in the figure, this application provides a method for obtaining quasi-co-location information, including:

[0040] Step 201: The terminal obtains the first quasi-co-address QCL type indicated by the Transmission Configuration Indicator (TCI) status, wherein the first QCL type is determined based on the terminal's capabilities.

[0041] Optionally, the first quasi-co-located QCL type is activated or configured via Radio Resource Control (RRC) signaling, Media Access Control Element (MAC CE) or Downlink Control Information (DCI).

[0042] Optionally, prior to step 201 above, the terminal reports its capabilities to the network-side device. Terminal capabilities include strong terminal capabilities and weak terminal capabilities. As an optional implementation, the protocol defaults to all terminals having strong terminal capabilities.

[0043] Strong terminal capability can refer to the ability of an advanced receiver (such as an AI or neural network-based receiver, i.e., using AI or neural network-based algorithms or modules for signal transmission, reception or demodulation) to obtain, or not require obtaining from the reference signal, at least one of the following large-scale parameters: Doppler shift, Doppler spread, average delay, and delay spread.

[0044] In this embodiment, the first quasi-co-located QCL type of the Transmission Configuration Indication (TCI) state indication is determined based on the terminal's capabilities. This ensures that the first quasi-co-located QCL type of the TCI state indication is compatible with the terminal's capabilities, thereby effectively avoiding the waste of reference resources and reducing reference signal overhead. For example, for terminals with stronger capabilities or those using more powerful receivers, which require fewer reference resources, a QCL type with fewer reference signals can be indicated. Conversely, for terminals with weaker capabilities, which require more reference resources, a QCL type with more reference signals can be indicated.

[0045] Optionally, the method for obtaining quasi-co-address information in this application embodiment further includes:

[0046] The terminal transmits or receives signals or channels according to the first QCL type.

[0047] Optionally, if the terminal's capability is a first capability, the first QCL type is a QCL type selected from a first set;

[0048] And / or, if the terminal's capability is a second capability, the first QCL type is a QCL type selected from a second set, a third set, or a fourth set; or, the first QCL type is a QCL type selected from the union of at least two sets from the first set, the second set, the third set, and the fourth set; or, the first QCL type is a QCL type selected from a fifth set.

[0049] Wherein, the first parameter value corresponding to the first set is greater than the first parameter value corresponding to the second set, or greater than the first parameter value corresponding to the third set, or greater than the first parameter value corresponding to the fourth set, or greater than the first parameter value corresponding to the fifth set;

[0050] The first parameter value includes at least one of the following:

[0051] The number of reference signals;

[0052] Number of reference signal types;

[0053] The amount of resources occupied by the reference signal;

[0054] The number of large-scale parameters corresponding to the reference signal.

[0055] In this embodiment, the second capability can specifically be a strong terminal capability, and the first capability is a weak terminal capability. Optionally, the large-scale parameters include at least one of Doppler offset, Doppler spread, average delay, delay spread, average gain, and spatial reception parameters. For a weak-capability terminal, when transmitting channels or signals, the terminal expects the first QCL type indicated by the TCI state to be selected from a first set. For a strong-capability terminal, when transmitting channels or signals, the terminal expects the first QCL type indicated by the TCI state to be selected from a second set, a third set, or a fourth set, or from the union of at least two sets of the first, second, third, and fourth sets, or from a fifth set.

[0056] For example, when the terminal can obtain the average delay and delay spread on its own or does not need to obtain them from the reference signal, the third set mentioned above includes QCL type B and the reference signal corresponding to the QCL type B, or includes QCL type B, the reference signal corresponding to the QCL type B, and QCL type D and the reference signal corresponding to the QCL type D.

[0057] For example, when the terminal can obtain the Doppler spread and delay spread on its own or does not need to obtain them from the reference signal, the third set mentioned above includes QCL type C and the reference signal corresponding to the QCL type C, or includes QCL type C, the reference signal corresponding to the QCL type C, and QCL type D and the reference signal corresponding to the QCL type D.

[0058] Optionally, in this embodiment, a QCL type X is defined. When the terminal can obtain or does not need to obtain at least one of the large-scale parameters such as Doppler shift, Doppler spread, average delay, and delay spread from the reference signal, then the QCL type X includes at least one large-scale parameter other than the large-scale parameter that the terminal can obtain or does not need to obtain from the reference signal. For example, when the terminal can obtain or does not need to obtain the Doppler shift from the reference signal, then the QCL type X includes at least one of Doppler spread, average delay, and delay spread.

This ensures that the first quasi-co-location QCL type indicated by the TCI state matches the terminal's capabilities, thereby effectively avoiding the waste of reference resources and reducing reference signal overhead.
