Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, apparatus, device, and medium for configuring and determining a downlink control channel. Background Art

[0002] To ensure scheduling flexibility, one downlink control information (DCI) can schedule one physical downlink shared channel (PDSCH) or one physical uplink shared channel (PUSCH).

[0003] When a 960kHz sub-carrier spacing (SCS) is used, the corresponding slot duration is 1 / 64ms. In this case, if each PDSCH is scheduled with a separate DCI, the DCI monitoring overhead will be too high.

[0004] In a multi-TTI (Multi-Transmission Time Interval, Multi-TTI) scheduling scenario, one DCI can schedule PDSCH or PUSCH for multiple time slots. An example of a multi-TTI PDSCH scheduling scenario is as follows: one DCI can schedule four PDSCHs, which correspond to four consecutive time slots. These four PDSCHs can be used to transmit different data, namely different transport blocks (TBs). Using multi-TTI scheduling can reduce the number of DCIs and reduce the complexity of UE monitoring DCI.

[0005] In a multi-TTI PDSCH scheduling scenario, the number of PDSCHs scheduled by a DCI may be semi-statically configured by a higher layer, or may be dynamically indicated by the DCI after a value range is indicated by a protocol or configured by higher layer signaling. Summary of the Invention

[0054] The embodiments of the present disclosure are now further described with reference to the accompanying drawings and specific implementation methods.

[0055] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0056] The Transmission Configuration Indication (TCI) in NR is used to indicate the Quasi Co-Location (QCL) of two signals on the spatial channel. QCL represents the degree of similarity between two signals on the spatial channel. The large-scale parameters of the channel experienced by the symbols on a certain antenna port corresponding to the QCL can be inferred from the channel experienced by the symbols on another antenna port. The large-scale parameters may include delay spread, average delay, Doppler spread, Doppler shift, average gain, and spatial receive parameters (Spatial Rx Parameter). The spatial receive parameters (Spatial Rx Parameter) correspond to the relevant information of the transmitted light beam.

[0057] NR divides several large-scale parameters into the following four categories to facilitate system configuration based on different UE scenarios:

[0058] QCL-Type A,

[0059] QCL-Type B

[0060] QCL-Type C

[0061] QCL-Type D.

[0062] in,

[0063] The large-scale parameters corresponding to QCL type A include: delay spread, average delay, Doppler spread, and Doppler shift.

[0064] The large-scale parameters corresponding to QCL type B include: Doppler spread and Doppler shift.

[0065] The large-scale parameters corresponding to QCL type C include: Doppler shift and average delay.

[0066] The large-scale parameters corresponding to QCL type D include: Spatial Rx Parameter.

[0067] QCL type D is used to indicate information about transmission beams of two signals.

[0068] If a DCI-scheduled multi-TTI PDSCH includes two types of PDSCHs, where the scheduling offset between one PDSCH and the PDCCH is less than a preset threshold, and the scheduling offset between the other PDSCH and the PDCCH is greater than or equal to a preset threshold, where the preset threshold can be TimeDurationForDCL, how to determine the QCL information of the PDSCH in this case becomes a problem that needs to be solved.

[0069] The present disclosure provides a method for configuring a downlink control channel, which is performed by a network-side device. The network-side device may be a base station device. The method includes:

[0070] A multi-TTI PDSCH scheduled by DCI is configured, where the QCL of each PDSCH in the multi-TTI PDSCH is the same as the TCI of the control resource set CORESET with the smallest index in the search space in the time slot closest to the PDSCH monitored by the user equipment.

[0071] This method is applicable to a scenario where one DCI schedules multiple TTI PDSCHs, and each PDSCH in the multiple TTI PDSCHs corresponds to the same transport block (TB) for repeated transmission.

[0072] This method is also applicable to the scenario where one DCI schedules multiple TTI PDSCHs, and different PDSCHs in the multiple TTI PDSCHs correspond to different transport blocks.

[0073] The embodiment of the present disclosure provides a method for configuring a downlink control channel, which is executed by a network side device. The network side device may be a base station device. Figure 1 , Figure 1 FIG. 1 is a flow chart showing a method for configuring a downlink control channel according to an exemplary embodiment.

[0075] In one embodiment, the preset threshold is defined as TimeDurationForQCL.

[0076] In one embodiment, the unit of the preset threshold is a time domain symbol.

[0077] In one embodiment, the preset threshold is a value configured by the base station.

[0078] In one embodiment, the preset threshold is a value related to the SCS configured by the base station. For example, when the SCS is 60 kHz, the value is configured as 7 time domain symbols.

[0079] In an embodiment of the present disclosure, the multi-TTI PDSCH configured for DCI scheduling includes only the first type of PDSCH, or only the second type of PDSCH, or both the first type of PDSCH and the second type of PDSCH.
