– upon detection of a PDCCH of the serving cell with DCI format 1, 1A, 1B, 1C, 1D, 2, 2A, 2B, 2C, or 2D intended for the UE in a subframe, or
– upon detection of an EPDCCH of the serving cell with DCI format 1, 1A, 1B, 1D, 2, 2A, 2B, 2C, or 2D intended for the UE in a subframe, or
– upon detection of a PDCCH of the serving cell with DCI format 7-1A, 7-1B, 7-1C, 7-1D, 7-1E, 7-1F, 7-1G intended for the UE in the first slot/subslot of a subframe
– upon detection of a SPDCCH of the serving cell with DCI format 7-1A, 7-1B, 7-1C, 7-1D, 7-1E, 7-1F, 7-1G intended for the UE in a slot/subslot
decode the corresponding PDSCH in the same subframe/slot/subslot with the restriction of the number of transport blocks defined in the higher layers, unless specified otherwise.
For a given serving cell, if the UE is configured with higher layer parameter blindSubframePDSCH-Repetitions, the UE shall upon detection of a PDCCH/EPDCCH with DCI format 1A with CRC scrambled by C-RNTI in UE-specific search space of subframe n, intended for the UE, decode, starting from subframe n, the corresponding PDSCH transmission in k consecutive DL subframe(s) according to the PDCCH information, where the value of k is determined by the repetition number field in the corresponding DCI. For k>1,
– if the UE is configured with transmission mode 1, 2, 3, 4, 5, 6, 7 or 8 for the serving cell, the k consecutive DL subframes do not include MBSFN subframe(s).
– the UE shall assume the truncated modulation and coding scheme field is interpreted such that the modulation and coding scheme corresponding to DCI format 1A is determined from MCS indices 0 through 15 if the higher layer parameter MCS-restrictionSubframePDSCH-Repetitions is set to ‘1’.
– The UE shall assume all the k PDSCH data transmissions are received in the same resource blocks.
– For TDD cell, the k consecutive DL subframes include the k DL subframes or special subframes according to the UL/DL configuration indicated by higher layer parameter subframeAssignment for the serving cell.

For k>1,
– the UE is not expected to receive the PDSCH data transmissions with more than two transmission layers.
– if the k consecutive DL slots/subslots cross two consecutive subframes with different downlink transmission modes, the UE is not expected to receive the PDSCH data transmissions after the former subframe.
– for DCI format 7-1F/7-1G, the UE shall assume the value of the DMRS position indicator field (defined in 3GPP TS 36.212 [4]) is set to ‘0’.
– the UE shall assume the modulation and coding scheme corresponding to DCI format 7-1A/7-1B/7-1C/7-1D/7-1E/7-1F/7-1G is determined from MCS indices 0 through 15 if the higher layer parameter MCS-restrictionSlotSubslotPDSCH-Repetitions is set to ‘1’.

– the UE shall assume the "precoding information" field is applied to all the k PDSCH data transmissions signaled via PDCCH/SPDCCH with DCI format 7-1C.
– the UE shall assume the "TPMI information for precoding" field is applied to all the k PDSCH data transmissions signaled via PDCCH/SPDCCH with DCI format 7-1D.
– the UE shall assume all the k PDSCH data transmissions are received in the same resource blocks.
– For FDD cell,
– the UE may assume that the same precoder applies to all scheduled k PDSCH transmissions.
– subslot 0 of a subframe is not counted as a DL subslot for k PDSCH transmissions if the CFI value is 2 or 3.
– For TDD cell,
– the UE may assume that the same precoder applies to those of the k scheduled PDSCH transmissions occur between guard periods of two adjacent special subframes.
– the k consecutive DL slots include the k DL slots of DL subframe or DwPTS according to the UL/DL configuration indicated by higher layer parameter subframeAssignment for the serving cell.
For BL/CE UEs, the set of BL/CE DL subframes is indicated as follows
– If DL resource reservation is enabled for the UE as specified in [11],
– for PDSCH transmission associated with C-RNTI or SPS C-RNTI using UE-specific MPDCCH search space including PDSCH transmission without a corresponding MPDCCH,
– if the Resource reservation field in the DCI is set to 0, then the set of BL/CE DL subframes corresponds to all downlink subframes and special subframes during the PDSCH transmission;
– if the Resource reservation field in the DCI is set to 1, then the set of BL/CE DL subframes corresponds to all downlink subframes and special subframes that are not fully reserved according to higher layer parameters (a subframe is considered fully reserved if and only if all OFDM symbols of all PRBs of the PDSCH transmission are reserved in the subframe);
– for MPDCCH transmission associated with C-RNTI or SPS C-RNTI using UE-specific MPDCCH search space,

If a UE is configured with more than one serving cell and if the frame structure type of any two configured serving cells is different, then the UE is considered to be configured for FDD-TDD carrier aggregation.
Except for MBMS reception, the UE is not required to monitor PDCCH with CRC scrambled by the SI-RNTI on the PSCell.
A UE may assume that positioning reference signals are not present in resource blocks in which it shall decode PDSCH according to a detected PDCCH with CRC scrambled by the SI-RNTI or P-RNTI with DCI format 1A or 1C intended for the UE.

Otherwise, the configured UE shall assume that for the given serving cell the carrier indicator field is present in PDCCH/EPDCCH located in the UE specific search space described in Clause 9.1 when the PDCCH/EPDCCH CRC is scrambled by C-RNTI or SPS C-RNTI.
If a UE is configured by higher layers to decode PDCCH with CRC scrambled by the SI-RNTI, the UE shall decode the PDCCH and the corresponding PDSCH according to any of the combinations defined in Table 7.1-1. The scrambling initialization of PDSCH corresponding to these PDCCHs is by SI-RNTI.
