Abstract
A base station configures a first set of subframes on a first carrier as special subframes. The base station transmits at least one unicast control message to a wireless device. The at least one unicast control message configures a second carrier. The base station configures the second carrier to enter a special subframe for every subframe in which the first carrier enters a special subframe, and the second carrier is activated.
Claims20
A method comprising:
- a) configuring, by a base station configured to communicate a plurality of carriers transmitting symbols in a sequential series of subframes, a first set of subframes on a first carrier in said plurality of carriers designated as special subframes;
- and
- b) transmitting, by said base station, at least one unicast radio resource control message to a wireless device, said at least one unicast radio resource control message:
- i) configured to cause configuration of:
- (1) a second carrier;
- and
- (2) cross carrier scheduling for said wireless device, said cross carrier scheduling configuration indicating that said first carrier carries scheduling information for packets transmitted to said wireless device on a data channel of said second carrier;
- and
- ii) comprises:
- (1) an index identifying a frequency of said second carrier;
- (2) at least one physical layer parameter of said second carrier;
- and
- (3) at least one measurement parameter of said second carrier;
- and
- c) configuring, by said base station, said second carrier to enter a special subframe for every subframe in which:
- i) said first carrier enters a special subframe;
- ii) said cross carrier scheduling is configured;
- and
- iii) said second carrier is activated;
- and
- wherein a majority of symbols of each special subframe have:
- i) no signal being transmitted by said base station;
- or
- ii) signals being transmitted at a special subframe power level that is substantially lower than a transmit power during a non-special subframe.
21 more elements
A base station, configured to communicate a plurality of carriers transmitting symbols in a sequential series of subframes, comprising:
- a) one or more communication interfaces;
- b) one or more processors;
- and
- c) memory storing instructions that, when executed, cause said base station to:
- i) configure each of a first set of subframes on a first carrier in said plurality of carriers designated as special subframes;
- and
- ii) transmit at least one unicast radio resource control message to a wireless device, said at least one unicast radio resource control message is configured to cause configuration of cross carrier scheduling for a wireless device, said cross carrier scheduling configuration indicating that said first carrier carries scheduling information for packets transmitted to said wireless device on a data channel of a second carrier in said plurality of carriers;
- and
- iii) configure said second carrier to enter a special subframe for every subframe in which:
- (1) said first carrier enters a special subframe;
- (2) said cross carrier scheduling is configured;
- and
- (3) said second carrier is activated;
- and
- wherein a majority of symbols of each special subframe have:
- (1) no signal being transmitted by said base station;
- or
- (2) signals being transmitted at a special subframe power level that is substantially lower than a transmit power during a non-special subframe.
