The following will compare and illustrate the processing manners that the terminal device and the network device of the present application can take in different situations through a number of examples.

In the application, the network device can transmit the PDCCH used for scheduling the primary carrier through the search space configured on the primary carrier, wherein the DCI is carried and transmitted through the PDCCH, and the network device can also transmit the PDCCH used 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.

Among them, the network equipment configures the search space for the primary carrier and the secondary carrier, and the search space should be avoided to overlap in time during configuration. When the network equipment transmits the PDCCH used to schedule the primary carrier, it can select the available search space at that time or at the latest time. . Correspondingly, the terminal equipment does not expect the search spaces configured by the primary carrier and the secondary carrier to overlap in time.

Figures 4A, 4B and 4C schematically illustrate various situations in which the search spaces of the primary carrier and the secondary carrier configured by the network do not overlap in time, and the terminal device can perform detection in the two search spaces without repeated searches. .

For comparison, Figures 5A, 5B and 5C schematically illustrate various situations in which the search spaces of the network configuration primary carrier and secondary carrier overlap in time. In these cases, if detection is performed in each search space , there will be problems of repeated searches and high search complexity. 4A-C and 5A-C, the white squares represent the search space of the first carrier, and the white squares represent the search space of the second carrier.

Exemplarily, according to the solutions provided by the embodiments of the present application, at least one of the following methods may be adopted for processing. In the following figures, a cross indicates that the search space is skipped, that is, the terminal does not perform detection in the search space, The absence of a cross indicates that the terminal detects DCI in this search space.

① Referring to FIG. 6 , if the overlapping search spaces are the common search space of the first carrier and the terminal-specific search space of the second carrier, the terminal detects DCI in the common search space of the first carrier.

2. Referring to Figure 7, if there is a common search space for the first carrier in time unit 1, and there is a time overlap between the search space on the first carrier and the terminal-specific search space for the second carrier in time unit 1, then in the first carrier DCI is detected on the search space of a carrier.

3. With reference to Fig. 8, if the overlapping search spaces are the common search space of the first carrier and the common search space of the second carrier, the first carrier is the carrier corresponding to the primary cell, and the second carrier is the carrier corresponding to the secondary cell, then The terminal detects DCI in the common search space of the first carrier.

4. With reference to Figure 9, if the overlapping search spaces are the terminal-specific search space of the first carrier and the terminal-specific search space of the second carrier, the first carrier is the carrier corresponding to the primary cell, and the second carrier is the carrier corresponding to the secondary cell. , the terminal detects DCI in the terminal-specific search space of the second carrier.

5. Referring to FIG. 10, if the overlapping search spaces are the terminal-specific search space of the first carrier and the terminal-specific search space of the second carrier, when the network configuration search space overlaps, the search space of the first carrier is used to detect DCI, then the terminal DCI is detected in the terminal-specific search space of the first carrier.

6. Referring to Figure 11, if the overlapping search spaces are the terminal-specific search space of the first carrier and the terminal-specific search space of the second carrier, when the network configures the search space, the number of search space types configured for the first carrier is larger, Or the number of DCI format configurations is large, or the number of aggregation level configurations of the DCI format is large, 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 space overlaps, at least one of the above-described embodiments can be used to avoid repeated detection, shorten detection time, and reduce network-side scheduling complexity.
