Transmission and reception method of MTC device located in cell coverage expansion area
A disclosure of the present specification provides a transmission and reception method of a machine type communication (MTC) device. The transmission and reception method of the MTC device may comprise the steps of: receiving first scheduling information indicating that a bundle of first data can be transmitted or received in multiple first sub-frames; and receiving second scheduling information indicating that a bundle of second data can be transmitted or received in multiple second sub-frames. Herein, when a physical resource block (PRB) of some sub-frames of the multiple first sub-frames overlaps a PRB of some sub-frames of the multiple second sub-frames, only one of the bundle of the first data and the bundle of the second data can be transmitted and received in the overlapping sub-frame.
1. A transmission and reception method, comprising:
receiving a first physical downlink control channel (PDCCH) including first scheduling information;
receiving a first bundle of first physical downlink shared channels (PDSCHs) repeated in a plurality of first subframes, the first bundle received based on the first scheduling information;
receiving a second PDCCH including second scheduling information; and
receiving a second bundle of second PDSCHs repeated in a plurality of second subframes, the second bundle received based on the second scheduling information,
wherein the second PDCCH is received after receiving the first bundle,
wherein only one first bundle or second bundle is transmitted or received in an overlapping subframe when a physical resource block (PRB) of the first PDSCHs on some of the plurality of first subframes overlaps a PRB of the second PDSCHs on some of the plurality of second subframes,
wherein the first bundle is transmitted or received when the first bundle includes cell-specific data,
wherein the second bundle is transmitted or received when the second bundle includes user equipment-specific data, and
wherein a bundle comprises repeated transmission on a plurality of subframes.
2. The method of claim 1 , wherein the other of the first and second bundle is punctured in an overlapping PRB when only the first or second bundle is transmitted.
3. The method of claim 1 , wherein transmission or reception of the first bundle is maintained and transmission or reception of the second bundle is dropped in an overlapping subframe.
4. The method of claim 1 , wherein transmission or reception of the first bundle is maintained and transmission or reception of the second bundle is delayed in an overlapping subframe.
5. The method of claim 1 , wherein both the first and second bundle are transmitted or received when part of the plurality of first subframes overlap part of the plurality of second sub-frames but no PRBs overlap each other.
6. An apparatus comprising:
a transceiver configured to transmit and receive signals; and
a processor coupled to a memory and configured to control the transceiver to:
receive a first physical downlink control channel (PDCCH) including first scheduling information;
receive a first bundle of first physical downlink shared channels (PDSCHs) repeated in a plurality of first subframes, the first bundle received based on the first scheduling information;
receive a second PDCCH including second scheduling information; and
receive a second bundle of second PDSCHs repeated in a plurality of second subframes, the second bundle received based on the second scheduling information,
wherein the second PDCCH is received after receiving the first bundle,
wherein only the first bundle or second bundle is transmitted or received in an overlapping subframe when a physical resource block (PRB) of the first PDSCHs on some of the plurality of first subframes overlaps a PRB of the second PDSCHs on some of the plurality of second subframes,
wherein the first bundle is transmitted or received when the first bundle includes cell-specific data,
wherein the second bundle is transmitted or received when the second bundle includes user equipment-specific data, and
wherein a bundle comprises repeated transmission on a plurality of subframes.
7. The apparatus of claim 6 , wherein the other of the first and second bundle is punctured in an overlapping PRB when only the first or second bundle is transmitted.
8. The apparatus of claim 6 , wherein transmission or reception of the first bundle is maintained and transmission or reception of the second bundle is dropped in an overlapping subframe.
9. The apparatus of claim 8 , wherein transmission or reception of the first bundle is maintained and transmission or reception of the second bundle is dropped in an overlapping subframe.
10. The apparatus of claim 6 , wherein transmission or reception of the first bundle is maintained and transmission or reception of the second bundle is delayed in an overlapping subframe.
11. The apparatus of claim 6 , wherein both the first and second bundle are transmitted or received when part of the plurality of first subframes overlap part of the plurality of second sub-frames but no PRBs overlap each other.
