Abstract

A method in a wireless communication terminal includes receiving configuration signaling for transmitting on a first set of radio resources wherein transmitting only on the first set of radio resources leads to a time-domain periodic repetitive pattern of transmissions from the terminal in a transmission interval that causes interference to a companion device communicably coupled to the wireless communication terminal. The terminals selects a second set of radio resources for transmitting on in the transmission interval such that transmissions on a combination of the second set of radio resources and the first set of radio resources does not lead to a periodic repetitive pattern of transmissions from the terminal in the transmission interval.

Claims

1. A method in a wireless communication terminal, the method comprising:

receiving, from a base station, configuration signaling for transmitting on a first set of radio resources wherein transmitting only on the first set of radio resources leads to a time-domain periodic repetitive pattern of transmissions from the terminal in a transmission interval,

the time-domain periodic repetitive pattern of transmissions from the terminal in the transmission interval causes interference to a companion device communicably coupled to the wireless communication terminal;

selecting a second set of radio resources for transmitting on in the transmission interval such that transmissions on a combination of the second set of radio resources and the first set of radio resources does not lead to a periodic repetitive pattern of transmissions from the terminal in the transmission interval; and

transmitting on the first and the second set of radio resources in the transmission interval.

2. The method of claim 1, transmitting in the first set of radio resources includes transmitting control information or data, and transmitting in the second set of resources includes transmitting dummy information that is not intended to be decoded by an entity receiving the dummy information.

3. The method of claim 1 further comprising:

receiving, from a base station, information identifying a candidate set of radio resources;

selecting the second set of radio resources from the candidate set of radio resources.

4. The method of claim 3, wherein receiving information identifying the candidate set of radio resources includes receiving information identifying a set of frequency domain resource blocks.

5. The method of claim 3, wherein the information identifying the candidate set of radio resources is received by the wireless communication terminal in a system information block transmitted by the base station.

6. The method of claim 3, wherein the information identifying the candidate set of radio resources includes receiving, from the base station, information identifying a semi-persistently scheduled Physical Uplink Shared Channel (PUSCH) resource periodically occurring in the transmission interval.

7. The method of claim 3, wherein the information identifying the candidate set of radio resources includes receiving a Physical Uplink Control Channel (PUCCH) resource index from the base station.

8. The method of claim 1,

transmitting in the first set of radio resources includes transmitting within a carrier bandwidth assigned to the wireless communication terminal, and

transmitting in the second set of radio resources includes transmitting outside of the assigned carrier bandwidth.

9. The method of claim 1 further comprising:

detecting the presence of the companion device communicably coupled to the wireless communication terminal,

transmitting in the second set of radio resources only when the presence of the companion device has been detected.

10. The method of claim 1, selecting the second set of radio resources such that the second set of radio resources are distinct from the first set of radio resources in time domain.

11. The method of claim 3, selecting the second set of radio resources from the candidate set of radio resources includes selecting the second set of radio resources such that the second set of radio resources have a pseudo-random transmission pattern in the time domain.

12. The method of claim 3, selecting the second set of radio resources from the candidate set of radio resources includes selecting the second set of radio resources such that the second set of radio resources is a subset of the candidate set of radio resources.

13. The method of claim 1, wherein the periodic repetitive pattern of the first set of radio resources has a periodicity rate or a multiple of the periodicity rate in an audible frequency range.

14. The method of claim 1, transmitting, by the wireless communication terminal, to the base station, information indicating detection of the companion device before transmitting in the second set of radio resources.

15. The method of claim 13, selecting the second set of radio resources from the candidate set of radio resources includes selecting resources from the candidate set of radio resources to reduce the periodicity rate or a multiple of the periodicity rate in an audible frequency range of the resulting transmitted waveform in the time domain.
