## Abstract

Control information (126) related to the reception of data (128) within a subframe (116) is transmitted over multiple subframes (113, 116) over multiple carrier (107, 108) from communication system infrastructure (102). A controller (134) in a mobile wireless communication device (104) reconstructs the control information (126) received over multiple subframes (113, 116) based on at least some control information (130) in a first physical control channel (118) in a first subframe (113) transmitted over a first carrier (107) and at least some other control information (132) in a second physical control channel (120) in a second subframe (116) transmitted over a second carrier (108).

## Claims

### Claim 1

A wireless communication device comprising:
a receiver configured to receive a first subframe having a first physical control channel comprising first control information and a second subframe having a second physical control channel comprising second control information, wherein the first subframe and the second subframe do not overlap in a time direction, and both the first control information and the second control information are associated with a third physical data channel comprising data; and
a controller configured to obtain the data from the third physical data channel, using at least one of the first control information and the second control information.

### Claim 2 (depends on 1)

The wireless communication device of claim 1, wherein the third physical data channel is transmitted on another subframe different from the first subframe.

### Claim 3

A method for a wireless communication device comprising:
receiving a first subframe having a first physical control channel comprising first control information and a second subframe having a second physical control channel comprising second control information, wherein the first subframe and the second subframe do not overlap in a time direction, and both the first control information and the second control information are associated with a third physical data channel comprising data; and
obtaining the data from the third physical data channel, using at least one of the first control information and the second control information.

### Claim 4

A base station comprising:
a transmitter configured to transmit a first subframe having a first physical control channel comprising first control information and a second subframe having a second physical control channel comprising second control information,
wherein the first subframe and the second subframe do not overlap in a time direction, both the first control information and the second control information are associated with a third physical data channel comprising data, and the data is obtained from the third physical data channel using at least one of the first control information and the second control information.
