In the following, a plurality of examples are used to describe how the terminal device and the network device can perform processing in different situations.
In application, the network device may transmit the PDCCH for scheduling the primary carrier through the search space configured on the primary carrier, where the DCI is carried and transmitted through the PDCCH, and the network device may also transmit the PDCCH for scheduling the primary carrier through the search space configured on the secondary carrier. Correspondingly, the terminal device may schedule the primary carrier through the PDCCH detected in the search space of the primary carrier, and may also schedule the primary carrier through the PDCCH detected in the search space of the secondary carrier.

Correspondingly, the terminal device does not expect the search spaces of the primary carrier and the secondary carrier configurations to overlap in time.
Fig. 4A, 4B, and 4C schematically illustrate various cases where the search spaces of the primary carrier and the secondary carrier of the network configuration do not overlap in time, and the terminal device can detect in both search spaces without repeated searches.
In comparison, fig. 5A, 5B and 5C schematically show a plurality of cases where the search spaces of the network configuration primary carrier and secondary carrier overlap in time, and in these cases, if detection is performed in each search space, there will be a problem that repeated search and search complexity is high. In fig. 4A-C and fig. 5A-C, white squares represent the search space of the first carrier, and white squares represent the search space of the second carrier.
Illustratively, according to the scheme provided by the embodiment of the present application, at least one of the following manners may be adopted, and in each of the drawings mentioned below, the cross indicates that the search space is skipped, that is, the terminal does not detect in the search space, and the absence of the cross indicates that the terminal detects DCI in the search space.
(1) Referring to fig. 6, if there are overlapping search spaces that are a common search space of a first carrier and a terminal-specific search space of a second carrier, respectively, the terminal detects DCI in the common search space of the first carrier.
(2) Referring to fig. 7, if there is a common search space for a first carrier in time cell 1 and there is an overlap in time between the search space on the first carrier and a terminal-specific search space for a second carrier in time cell 1, DCI is detected on the search space of the first carrier.
(3) Referring to fig. 8, if there are overlapping search spaces that are a common search space of a first carrier and a common search space of a second carrier, respectively, the first carrier being a carrier corresponding to a primary cell, and the second carrier being a carrier corresponding to a secondary cell, the terminal detects DCI in the common search space of the first carrier.
(4) Referring to fig. 9, if there are overlapping search spaces, which are a terminal-specific search space of a first carrier and a terminal-specific search space of a second carrier, respectively, the first carrier being a carrier corresponding to a primary cell and the second carrier being a carrier corresponding to a secondary cell, the terminal detects DCI in the terminal-specific search space of the second carrier.
(5) Referring to fig. 10, if there are overlapping search spaces, which are a terminal-specific search space of a first carrier and a terminal-specific search space of a second carrier, respectively, and a network configuration search space overlaps, DCI is detected using the search space of the first carrier, the terminal detects DCI in the terminal-specific search space of the first carrier.
(6) Referring to fig. 11, if there are overlapping search spaces, that is, a terminal-specific search space of a first carrier and a terminal-specific search space of a second carrier, respectively, and when a network configures the search spaces, the number of search space type configurations configured for the first carrier is greater, or the number of DCI format configurations is greater, or the number of aggregation level configurations for the DCI formats is greater, the terminal detects DCI in the terminal-specific search space of the first carrier.
It can be seen that, with the embodiments of the present application, if the search spaces overlap, at least one of the above-described embodiments may be adopted to process, so as to achieve the purposes of avoiding repeated detection, shortening detection time, and reducing scheduling complexity at the network side.
The specific arrangement and implementation of the embodiments of the present application are described above from different perspectives by way of a plurality of embodiments.
