FIELD: communication equipment.
SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. To this end, the technology for performing the indexing of localized enhanced control channel (eCCE) elements and distributed eCCEs for ePDCCH in a radio frame is described. One method includes the steps of indexing localized eCCE and distributed eCCE independently, based on the aggregation level, for transmission of the extended physical downlink control channel (ePDCCH). For example, physical localized eCCEs can be indexed in order of increasing frequency, while indexing is an aggregation level that is specifically mapped to physical indexes. For distributed eCCE logical indexing can also take into account coordinate area of intercellular interference (ICIC). Indices eCCE belonging to the search space for the given level of aggregation (AGGL) may be distributed over different coordinate regions ICIC. In addition, global logical indexing with AGGL can be applied to localized eCCE and distributed eCCE, with the logical indexes of localized eCCE and distributed eCCE alternating with each other. Area ICIC can also be taken into account in global indexing. Indexing eCCE considering AGGL can be used for the purpose of the ePDCCH and blind decoding and/or resource allocation for the ePDCCH. Physical indices eCCE can be used for producing implicit index for physical uplink control channel (PUCCH).
EFFECT: technical result consists in improvement of transmission capacity.
