Abstract

Claims (46)

1. A transceiver,

wherein the transceiver is configured to receive data in at least one transmission time interval on certain allocated resource elements of a wireless communication system;

wherein the transceiver is configured to receive a blanking pattern from another transceiver;

wherein the transceiver is configured to receive data in the transmission time interval using the blanking pattern,

wherein the transceiver is configured to receive data using a data signal, the data signal comprising a plurality of frames, each frame comprising a plurality of subframes, and each subframe comprising a number of symbols in the time domain and a number of sub-carriers in the frequency domain,

wherein the transmission time interval is defined by a predefined number of symbols in the time domain,

wherein the transmission time interval is shorter than one subframe.

2. The transceiver of claim 1 , configured to at least partially blank the transmission time interval by one or more of the following:

by blanking at least a subset of symbols in the time domain of the transmission time interval,

by blanking at least a subset of sub-carriers in the frequency domain of the transmission time interval,

by blanking at least a subset of resource elements of the transmission time interval in at least one out of time domain and frequency domain.

3. The transceiver of claim 1 , configured to signal to another transceiver a transmission grant for transmitting a reference signal in a blanked part of the at least partially blanked transmission time interval.

4. The transceiver of claim 1 , configured to blank at least one out of demodulation reference symbols and data symbols in the at least partially blanked transmission time interval.

5. The transceiver of claim 1 , configured to only transmit at least one out of reference symbols and demodulation reference symbols in the at least partially blanked transmission time interval.

6. The transceiver of claim 1 , configured to partially blank parts of the transmission time interval in at least one part out of time domain and frequency domain.

7. The transceiver of claim 1 , configured to use a blanked part of the at least partially blanked transmission time interval for transmitting or receiving a reference signal.

8. A transceiver,

wherein the transceiver is configured to transmit or receive data in at least one transmission time interval on certain allocated resource elements of a wireless communication system;

wherein the transceiver is configured to;

receive a blanking pattern from another transceiver;

wherein the data is received using a data signal, the data signal comprising a plurality of frames, each frame comprising a plurality of subframes, and each subframe comprising a number of symbols in the time domain and a number of sub-carriers in the frequency domain;

wherein the transmission time interval is defined by a predefined number of symbols in the time domain;

wherein the transmission time interval is shorter than one subframe;

wherein the data is received in the transmission time interval using the blanking pattern; and

transmit a reference signal in a blanked part of a at least partially blanked transmission time interval for a data block to be received by the transceiver; or

at least partially blanking the transmission time interval based on a blanking pattern received from another transceiver.

9. The transceiver of claim 8 , configured to transmit or receive data using a data signal, the data signal comprising a plurality of frames, each frame comprising a plurality of subframes, and each subframe comprising a number of symbols in the time domain and a number of sub-carriers in the frequency domain,

wherein the transmission time interval is defined by a predefined number of symbols in the time domain.

10. The transceiver of claim 9 , wherein the transmission time interval is shorter than one subframe.

11. The transceiver of claim 8 , wherein the transceiver is configured to transmit the reference signal to another transceiver in a blanked part of the at least partially blanked transmission time interval based on a transmission grant signaled by the other transceiver, the transmission grant indicating the blanked part of the at least partially blanked transmission interval to be used for transmitting the reference signal.

12. The transceiver of claim 8 , wherein at least a subset of symbols of the at least partially blanked transmission time interval are blanked in the time domain,

or wherein at least a subset of sub-carriers in the frequency domain of the transmission time interval are blanked,

or wherein at least a subset of resource elements of the transmission time interval is blanked in at least one out of time domain and frequency domain.

13. The transceiver of claim 8 , wherein a transmission time interval for a data block to be received by the transceiver in a downlink band or downlink time interval of the wireless communication system is at least partially blanked;

wherein the transceiver is configured to use a blanked part of the at least partially blanked transmission time interval for transmitting the reference signal.

14. The transceiver of claim 8 , wherein a downlink transmission time interval is at least partially blanked;

wherein the transceiver is configured to use a blanked part of the at least partially blanked downlink transmission time interval for transmitting an uplink reference signal to another transceiver in the downlink transmission time interval in the downlink frequency band or downlink time interval.

15. The transceiver of claim 8 , configured to receive a signal information indicating the parts of the downlink transmission time interval to be used by the transceiver to transmit the uplink reference signal.

16. The transceiver of claim 8 , configured to use a blanked part of the at least partially blanked transmission time interval for transmitting or receiving a control information.

17. A method for receiving data, comprising:

receiving data in at least one transmission time interval on certain allocated resource elements of a wireless communication system;

receiving a blanking pattern from another transceiver,

wherein the data is received in the transmission time interval using the blanking pattern,

wherein the data is received using a data signal, the data signal comprising a plurality of frames, each frame comprising a plurality of subframes, and each subframe comprising a number of symbols in the time domain and a number of sub-carriers in the frequency domain,

wherein the transmission time interval is defined by a predefined number of symbols in the time domain,

wherein the transmission time interval is shorter than one subframe.
