1. A method for a user equipment (UE) to receive a physical downlink shared channel (PDSCH) transmitted by a base station, the method comprising:
- receiving first information indicating one or more subframes in which the UE is configured to monitor a first type physical downlink control channel (PDCCH);
receiving third information indicating a symbol duration for receiving a second type PDCCH in a subframe;
determining a starting symbol for the PDSCH in a first subframe indicated by the first information, based on a second information indicating a start symbol for the first type PDCCH in a subframe, if the PDSCH is scheduled by the first type PDCCH in the first subframe and the second information is received;
determining the starting symbol for the PDSCH in the first subframe indicated by the first information, based on the third information, if the second information is not received;
determining the starting symbol for the PDSCH in a second subframe, which is not indicated by the first information, based on the third information, if the PDSCH is scheduled by the second type PDCCH in the second subframe; and
receiving, from a base station, the PDSCH based on the determined starting symbol.

Abstract
Methods and apparatus are described for forming Control Channel Elements (CCEs) from Resource Element Groups (REGs) that are located in one or more Physical Resource Block (PRB) pairs from a set of PRB pairs, for determining a first symbol in a Transmission Time Interval (TTI) for a Physical Downlink Shared Channel (PDSCH), and for determining whether the PDSCH includes all PRB pairs indicated by a respective PDCCH scheduling the PDSCH.

-
receiving first information indicating one or more subframes in which the UE is configured to monitor a first type physical downlink control channel (PDCCH); receiving third information indicating a symbol duration for receiving a second type PDCCH in a subframe; determining a starting symbol for the PDSCH in a first subframe indicated by the first information, based on a second information indicating a start symbol for the first type PDCCH in a subframe, if the PDSCH is scheduled by the first type PDCCH in the first subframe and the second information is received; determining the starting symbol for the PDSCH in the first subframe indicated by the first information, based on the third information, if the second information is not received; determining the starting symbol for the PDSCH in a second subframe, which is not indicated by the first information, based on the third information, if the PDSCH is scheduled by the second type PDCCH in the second subframe; and receiving, from a base station, the PDSCH based on the determined starting symbol. - View Dependent Claims (2, 3, 4, 5, 6)

7. A method for a base station to transmit a physical downlink shared channel (PDSCH) to a user equipment (UE), the method comprising:
-
transmitting, to the UE, first information indicating one or more subframes in which the UE is configured to monitor a first type physical downlink control channel (PDCCH); transmitting, to the UE, third information indicating a symbol duration for receiving a second type PDCCH in a subframe; determining a starting symbol for the PDSCH in a first subframe indicated by the first information, based on a second information indicating a start symbol for the first type PDCCH in a subframe, if the PDSCH is scheduled by the first type PDCCH in the first subframe and the second information is transmitted to the UE; determining the starting symbol for the PDSCH in the first subframe indicated by the first information, based on the third information, if the second information is not transmitted to the UE; determining the starting symbol for the PDSCH in a second subframe, which is not indicated by the first information, based on the third information, if the PDSCH is scheduled by the second type PDCCH in the second subframe; and transmitting the PDSCH based on the determined starting symbol. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus of a user equipment (UE) for receiving a physical downlink shared channel (PDSCH) transmitted from a base station, the apparatus comprising:
-
a receiver configured to receive first information indicating one or more subframes in which the UE is configured to monitor a first type physical downlink control channel (PDCCH), receive third information indicating a symbol duration for receiving a second type PDCCH in a subframe, and receive, from the base station, the PDSCH based on a starting symbol for the PDSCH; and a computing unit configured to determine the starting symbol for the PDSCH in a first subframe indicated by the first information, based on a second information indicating a start symbol for the first type PDCCH in a subframe, if the PDSCH is scheduled by the first type PDCCH in the first subframe and the second information is received, determine the starting symbol for the PDSCH in the first subframe indicated by the first information, based on the third information, if the second information is not received, and determine the starting symbol for the PDSCH in a second subframe, which is not indicated by the first information, based on the third information, if the PDSCH is scheduled by the second type PDCCH in the second subframe. - View Dependent Claims (14, 15, 16, 17, 18)

19. An apparatus of a base station for transmitting a physical downlink shared channel (PDSCH) transmitted to a user equipment (UE) the apparatus comprising:
-
a transmitter configured to transmit, to the UE, first information indicating one or more subframes in which the UE is configured to monitor a first type physical downlink control channel (PDCCH), transmit, to the UE, third information indicating a symbol duration for receiving a second type PDCCH in a subframe, and transmit, to the UE, the PDSCH based on a starting symbol for the PDSCH, and a computing unit configured to determine the starting symbol for the PDSCH in a first subframe indicated by the first information, based on a second information indicating a start symbol for the first type PDCCH in a subframe, if the PDSCH is scheduled by the first type PDCCH in the first subframe and the second information is transmitted to the UE, determine the starting symbol for the PDSCH in the first subframe indicated by the first information, based on the third information, if the second information is not transmitted to the UE, and determine the starting symbol for the PDSCH in a second subframe, which is not indicated by the first information, based on the third information, if the PDSCH is scheduled by the second type PDCCH in the second subframe. - View Dependent Claims (20, 21, 22, 23, 24)
