Interleaved mapping method and apparatus

An electronic device, comprising:

• a processor, and
• memory for storing instructions executable by the processor;
• wherein the processor is configured to
• interleave a virtual sequence of first physical resource element bundles according to an interleaving function, wherein the first physical resource element bundles comprise actual physical resource element bundles and one or more virtual physical resource element bundles;
• mark a physical resource element bundle in the interleaved first physical resource element bundles without any corresponding actual physical resource element bundle as an invalid physical resource element bundle;
• determine a first correspondence of the valid physical resource element bundles in the interleaved first physical resource element bundles with respect to an actual sequence of the actual physical resource element bundles;
• and
• determine, based on the first correspondence and a second correspondence of logical resource elements with respect to the actual sequence, a mapping relationship between the logical resource elements and the actual physical resource element bundles;
• wherein the processor is further configured to mark the physical resource element bundle in the interleaved first physical resource element bundles without any corresponding actual physical resource element bundle as the invalid physical resource element bundle by:
• determining a quantity of actual physical resource element bundles comprised in the first physical resource element bundles;
• determining, according to a relationship between an interleaving sequence number of an interleaved first physical resource element bundle and the quantity, the invalid physical resource element bundle in the interleaved first physical resource element bundles that does not correspond to any actual physical resource element bundle;
• and
• marking the invalid physical resource element bundle.

A non-transitory computer-readable storage medium storing a computer program that, when executed by one or more processing circuits, cause the one or more processing circuits to perform:

• interleaving a virtual sequence of first physical resource element bundles according to an interleaving function, wherein the first physical resource element bundles comprise actual physical resource element bundles and one or more virtual physical resource element bundles;
• marking a physical resource element bundle in the interleaved first physical resource element bundles without any corresponding actual physical resource element bundle as an invalid physical resource element bundle;
• determining a first correspondence of the valid physical resource element bundles in the interleaved first physical resource element bundles with respect to an actual sequence of the actual physical resource element bundles;
• and
• determining, based on the first correspondence and a second correspondence of logical resource elements with respect to the actual sequence, a mapping relationship between the logical resource elements and the actual physical resource element bundles;
• wherein said marking the physical resource element bundle in the interleaved first physical resource element bundles without any corresponding actual physical resource element bundle as the invalid physical resource element bundle comprises:
• determining a quantity of actual physical resource element bundles comprised in the first physical resource element bundles;
• determining, according to a relationship between an interleaving sequence number of an interleaved first physical resource element bundle and the quantity, the invalid physical resource element bundle in the interleaved first physical resource element bundles that does not correspond to any actual physical resource element bundle;
• and
• marking the invalid physical resource element bundle.
