Fig. 1 is a PDSCH resource allocation method provided in an embodiment of the present application, and as shown in fig. 1, an execution subject of the PDSCH resource allocation method provided in an embodiment of the present application may be a network side device, for example, a base station. The method comprises the following steps:

step 101, a network side device determines resources available for PDSCH transmission in a control resource set CORESET of a physical downlink control channel PDCCH.

Specifically, since the Redcap UE does not have a sufficient number of transceiving antennas, the PDCCH introduces more Aggregation Levels (AL) in order to guarantee communication quality.

The PDCCHs of different aggregation levels may have the same Control Channel Elements (CCEs) starting position, and after a new aggregation level is introduced, the existing protocol cannot provide a more complete scheme due to the increase of the number of aggregation levels related to the same aggregation level ambiguity at the starting point.

In the embodiment of the present application, the network side device performs PDSCH transmission by determining a Resource that can be used for PDSCH transmission in a Control Resource Set (core) of the PDCCH, so as to avoid the problem of aggregation level ambiguity.

For example, the network side device may notify the terminal of the resources available for PDSCH transmission in the core set of the PDCCH by sending configuration information to the terminal.

For another example, the network side device and the terminal may respectively determine resources available for PDSCH transmission in the core set of the PDCCH in a protocol agreed manner.

And after determining the available resources for PDSCH transmission in the CORESET of the PDCCH, the network side equipment sends PDSCH information through the resources for PDSCH transmission. And rate matching or puncturing (puncturing) for resources that are not available in the CORESET.

According to the method for configuring the physical downlink shared channel resources, the PDSCH information is transmitted by determining the resources which can be used for PDSCH transmission in the CORESET of the PDCCH, so that the fuzzy aggregation level is avoided.

the aggregation levels of the PDCCHs comprise aggregation levels except for a second aggregation level, and the starting CCEs of the PDCCHs of at least two aggregation levels are the same in position; the second aggregation level is K, K ∈ {1,2,4,8,16 }.

Specifically, in the embodiments of the present application, for a case where aggregation levels other than 1,2,4,8, and 16 are newly introduced and the positions of starting CCEs of PDCCHs of at least two aggregation levels are the same, resources other than the resource corresponding to the first aggregation level in the CORESET of the PDCCH are configured for PDSCH transmission.

And once the PDCCH aggregation level blindly detected by the terminal is lower than the maximum PDCCH aggregation level, reserving PDCCH resources according to the maximum PDCCH aggregation level, and using the rest resources for PDSCH transmission.

For example, if the aggregation levels of 6,12,24, and 32 are newly introduced, the maximum value 32 among the aggregation levels configured in the common search space is used, and at this time, resources other than the resources corresponding to the aggregation level 32 in the core set configured with the PDCCH are used for PDSCH transmission.

And once the PDCCH aggregation level blindly detected by the terminal is lower than the preset reference PDCCH aggregation level, reserving PDCCH resources according to the preset reference PDCCH aggregation level, and using the rest resources for PDSCH transmission.

The preset reference PDCCH aggregation level may be configured according to actual needs. For example, 32, or 24.

For example, an aggregation level of 6,12,24, or 32 is newly introduced, and if the preset reference PDCCH aggregation level is 32, resources other than the resources corresponding to the aggregation level 32 in the core set of the PDCCH are configured for PDSCH transmission.

For another example, an aggregation level of 6,12,24, and 32 is newly introduced, and if the preset reference PDCCH aggregation level is 24, resources other than the resources corresponding to the aggregation level 24 in the core set of the PDCCH are configured for PDSCH transmission.

The aggregation level of the high-level configuration can be set according to actual requirements. For example, it may be configured according to the capability of the terminal or according to the channel quality.

For example, an aggregation level of 6,12,24,32 is newly introduced, and if the aggregation level 32 is configured by a higher layer, resources other than the resources corresponding to the aggregation level 32 in the core set configured with the PDCCH are used for PDSCH transmission.

For another example, an aggregation level of 6,12,24,32 is newly introduced, and if the aggregation level 24 is configured by the higher layer, resources other than the resources corresponding to the aggregation level 24 in the CORESET configured with the PDCCH are used for PDSCH transmission.

The mode of determining the aggregation level according to the total number of CCEs in CORESET of the PDCCH can be set according to actual requirements. For example, the total number of CCEs in CORESET is equal to the aggregation level, or the total number of CCEs in CORESET is equal to 2 times the aggregation level.

For example, if the total number of CCEs in the CORESET is 32, resources other than the resource corresponding to the aggregation level 32 in the CORESET configured with the PDCCH are used for PDSCH transmission.

For another example, if the total number of CCEs in the CORESET is 24, resources other than the resource corresponding to the aggregation level 24 in the CORESET of the PDCCH are configured for PDSCH transmission.

Fig. 6 is a fifth schematic view of a resource allocation principle of a PDSCH provided in the embodiment of the present application, and as shown in fig. 6, symbols other than symbols occupied by CORESET configured on a PDCCH are used for PDSCH transmission.

For example, the PDCCH aggregation level is determined according to the number of CCEs within the CORESET, and mapping is turned on from symbols other than the CORESET. And once the PDCCH aggregation level which is blindly detected by the user is lower than the PDCCH aggregation level, reserving PDCCH resources according to symbols occupied by CORESET of the PDCCH, and configuring symbols except the symbols occupied by CORESET of the PDCCH for PDSCH transmission.
