Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and particularly 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 Physical Uplink Shared Channel (PUSCH).

[0003] When adopting a sub-carrier spacing (SCS) of 960 kHz, the corresponding slot time length is 1 / 64 ms. When such a large sub-carrier spacing and small slot time length result in each PDSCH being scheduled individually by one DCI, the overhead of DCI monitoring becomes too high.

[0004] In a multi-Transmission Time Interval (Multi-TTI) scheduling scenario, one DCI can schedule PDSCHs or PUSCHs in multiple slots. Taking an example in a multi-TTI PDSCH scheduling scenario, one DCI can schedule four PDSCHs, and these four PDSCHs sequentially correspond to four consecutive slots. These four PDSCHs can be used to transmit different data, i.e., different transport blocks (TBs). By adopting the multi-TTI scheduling method, the number of DCIs can be reduced, and the complexity for the UE to monitor DCIs can be reduced.

[0005] In the multi-TTI PDSCH scheduling scenario, the number of PDSCHs scheduled by one DCI may be statically set by the upper layer, and the protocol indicates the range of possible values, or after setting the range of possible values by upper layer signaling, it may also be dynamically indicated by this DCI.

DETAILED DESCRIPTION OF THE INVENTION

[0035] Here, embodiments of the present disclosure will be further described in conjunction with the drawings and specific embodiments.

[0036] Here, exemplary embodiments will be described in detail and the examples will be shown in the drawings. When the following description relates to the drawings, unless otherwise expressed, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments that are consistent with the embodiments of the present disclosure. Rather, they are merely examples of apparatuses and methods that are consistent with some aspects of the present disclosure, which are described in detail in the scope of the appended claims.

[0037] The Transmission Configuration Indication (TCI) in NR is used to indicate the Quasi Co-Location (QCL) of two signals in a spatial channel. QCL represents the similarity of two signals in a spatial channel. The large-scale parameters corresponding to the channel experienced by the symbol at a certain antenna port with QCL can be estimated from the channel experienced by the symbol at another antenna port. The large-scale parameters can include delay spread, average delay, Doppler spread, Doppler offset, average gain, and Spatial Rx Parameter. The Spatial Rx Parameter here corresponds to the information regarding the transmission beam.

[0038] In NR, by classifying several large-scale parameters into the following four types, it facilitates the system to set parameters based on different scenarios where the UE exists. QCL Type A, QCL Type B, QCL Type C, QCL Type D.

[0039] Here, The large-scale parameters corresponding to QCL Type A include delay spread, average delay, Doppler spread, and Doppler offset. The large-scale parameters corresponding to QCL Type B include Doppler spread and Doppler offset. The large-scale parameters corresponding to QCL Type C include Doppler offset and average delay. The large-scale parameters corresponding to QCL Type D include Spatial Rx Parameter. QCL Type D is used to indicate information about the transmission beams of two signals.

[0040] Two categories of PDSCH are simultaneously included in the multi-TTI PDSCH scheduled by one DCI. Here, the scheduling offset between one category of PDSCH and PDCCH is smaller than a preset threshold, and the scheduling offset between the other category of PDSCH and PDCCH is greater than or equal to the preset threshold. The preset threshold here may be TimeDurationForDCL. In this case, how to determine the QCL information of PDSCH is an issue to be solved.
