Abstract

The exemplary embodiments of the invention provide at least a method and apparatus for defining a set of parameters to establish a possibility for a single user equipment to transmit uplink data on a physical uplink shared channel via two or more clusters including adjacent resource blocks, where at least one of the clusters includes at least one blanked physical uplink control channel resource block and where at least one of the clusters includes at least one physical shared channel resource block, and transmitting the parameters to at least the single user equipment. Further, the exemplary embodiments of the invention provide at least a method and apparatus for receiving a set of parameters defining a physical uplink control channel and allocating physical/virtual resource blocks based at least on received physical uplink control channel configuration parameters, a received resource allocation and predefined physical resource block mapping rules.

Claims

1. A method, comprising:

defining a set of parameters to establish a possibility for a single user equipment to transmit uplink data on a physical uplink shared channel via two or more clusters including adjacent resource blocks, where at least one of the clusters includes at least one blanked physical uplink control channel resource block and where at least one of the clusters includes at least one physical shared channel resource block; and

transmitting the parameters to at least the single user equipment.

2. The method according to claim 1, where one parameter of the set of parameters specifies a total number of blank resource blocks and is comprised of a first parameter for a lower edge of a spectrum and a second parameter for an upper edge of the spectrum.

3. The method according to claim 2, where the parameter that specifies the number of blank resource blocks is transmitted in at least one of a master information block and a system information block.

4. The method according to claim 1, where one of the parameters in the set of parameters specifies that uplink resource allocation grant is interpreted as “

clustered resource allocation grant”

instead of “

localized resource allocation grant”

.

5. The method according to claim 1, where the transmitted parameters allow for the single user equipment to avoid transmitting data on those resource blocks occupied by the physical uplink control channel regardless of an uplink grant.

6. The method according to claim 1, where one parameter of the set of parameters specifies non-blanked physical uplink control channel resource blocks that are excluded from a physical uplink shared channel grant.

7. The method according to claim 1, where one parameter of the set of parameters specifies a location or locations, if any, of a physical uplink control channel fragment.

8. The method according to claim 7, where the parameter that specifies the location or locations, if any, of the physical uplink control channel fragment comprises at least two signaling bits for indicating one of:

no PUCCH blanking→

no PUSCH fragments available;

PUSCH fragment on the lower side of the spectrum;

PUSCH fragment on the upper side of the spectrum;

or

PUSCH fragments on both sides of the spectrum.

9. The method according to claim 7, where the parameter that specifies the location or locations, if any, of the physical uplink control channel fragment is transmitted in one of a master information block and a system information block.

10. The method according to claim 7, where the transmitted set of parameters indicates to the single user equipment the location of the physical uplink control channel fragment that is available for data transmission when interpreting an uplink grant.

11. A computer readable medium encoded with a computer program executable by a processor to perform actions comprising:

defining a set of parameters to establish a possibility for a single user equipment to transmit uplink data on a physical uplink shared channel via two or more clusters including adjacent resource blocks, where at least one of the clusters includes at least one blanked physical uplink control channel resource block and where at least one of the clusters includes at least one physical shared channel resource block; and

transmitting the parameters to at least the single user equipment.

12. The computer readable medium encoded with a computer program according to claim 11, where one parameter of the set of parameters specifies one of a number of blank resource blocks on each side of a spectrum and a total number of blank resource blocks.

13. An apparatus comprising:

at least one processor; and

at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least;

define a set of parameters to establish a possibility for a single user equipment to transmit uplink data on a physical uplink shared channel via two or more clusters including adjacent resource blocks, where at least one of the clusters includes at least one blanked physical uplink control channel resource block and where at least one of the clusters includes at least one physical shared channel resource block; and

transmit the parameters to at least the single user equipment.

14. The apparatus according to claim 13, where one parameter of the set of parameters specifies a total number of blank resource blocks and is comprised of a first parameter for a lower edge of a spectrum and a second parameter for an upper edge of the spectrum.

15. The apparatus according to claim 13, where one of the parameters in the set of parameters specifies that uplink resource allocation grant is interpreted as “

clustered resource allocation grant”

instead of “

localized resource allocation grant”

.

16. The apparatus according to claim 13, where the transmitted parameters allow for the single user equipment to avoid transmitting data on those resource blocks occupied by the physical uplink control channel regardless of an uplink grant.

17. The apparatus according to claim 13, where one parameter of the set of parameters specifies non-blanked physical uplink control channel resource blocks that are excluded from a physical uplink shared channel grant.

PUSCH fragment on the upper side of the spectrum;

or

PUSCH fragments on both sides of the spectrum.

20. The apparatus according to claim 18, where the parameter that specifies the location or locations, if any, of the physical uplink control channel fragment is transmitted in one of a master information block and a system information block.

21. The apparatus according to claim 18, where the transmitted set of parameters indicates to the single user equipment the location of the physical uplink control channel fragment that is available for data transmission when interpreting an uplink grant.
