Abstract

A communications node operable to communicate with another communications node over a communications channel having a plurality of frequency resources, the communications node includes data defining a division of the communications channel into a plurality of contiguous sub-bands each having N frequency resources, wherein each frequency resource in a sub-band has a corresponding frequency resource in each of the other sub-bands, data defining an initial allocation of the frequency resources, a resource determination module operable to apply a frequency shift to the initially allocated frequency resources in accordance with a frequency hopping sequence to determine frequency resources to use for communicating information with the other communications node, wherein the frequency shift applied moves the initially allocated frequency resources to corresponding frequency resources in another sub-band, a transceiver for communicating information with the other communications node using the determined frequency resource.

First claim

The invention claimed is:

1. A method performed by a first communication apparatus which communicates with a second communication apparatus, the method comprising:
receiving, from the second communication apparatus, information identifying a resource allocation within a transmission bandwidth comprising a plurality of narrower bands;
determining a transmission resource based on
the information,
a frequency shift added to the resource allocation, wherein the frequency shift comprises an integer number of the narrower bands; and
the transmission bandwidth; and

transmitting, to the second communication apparatus, uplink data using the at least one transmission resource.

2. A method according to the claim 1 , wherein the at least one transmission resource is determined based on a modulo arithmetic.

3. A method according to the claim 1 , wherein the at least one transmission resource is determined based on (X+Y) mod Z, where X is the resource allocation, Y is the frequency shift, mod is the modulo arithmetic and Z is the transmission bandwidth.

4. A method according to the claim 1 , wherein the resource allocation is an initial resource allocation for a first time period.

5. A method according to the claim 1 , wherein the resource allocation is for a second time period.

6. A method according to the claim 1 , wherein the first communications apparatus is a User Equipment (UE) and the second communications apparatus is a base station.

7. A method performed by a first communication apparatus which communicates with a second communication apparatus, the method comprising:
transmitting, to the second communication apparatus, information identifying a resource allocation within a transmission bandwidth comprising a plurality of narrower bands;
determining a transmission resource based on
the information,
a frequency shift added to the resource allocation, wherein the frequency shift comprises an integer number of the narrower bands; and
the transmission bandwidth; and

receiving, from the second communication apparatus, uplink data using the transmission resource.

8. A method according to the claim 7 , wherein the transmission resource is determined based on a modulo arithmetic.

9. A method according to the claim 7 , wherein the transmission resource is determined based on (X+Y) mod Z, where X is the resource allocation, Y is the frequency shift, mod is the modulo arithmetic and Z is the uplink bandwidth.

10. A method according to the claim 7 , wherein the resource allocation is an initial resource allocation for a first time period.

11. A method according to the claim 7 , wherein the resource allocation is for a second time period.

12. A method according to the claim 7 , wherein the first communications apparatus is a base station and the second communications apparatus is a User Equipment (UE).

13. A first communication apparatus which communicates with a second communication apparatus, the first communication apparatus comprising:
a transceiver circuit configured to receive, from the second communication apparatus, information identifying a resource allocation within a transmission bandwidth comprising a plurality of narrower bands; and
a processor configured to determine a transmission resource at least one resource based on
the first information,
a frequency shift added to the resource allocation, wherein the frequency shift comprises an integer number of the narrower bands; and
the transmission bandwidth,

wherein the transceiver circuit is further configured to transmit, to the second communication apparatus, uplink data using the transmission resource.

14. A first communication apparatus which communicates with a second communication apparatus, the first communication apparatus comprising:
a transceiver circuit configured to transmit, to the second communication apparatus, information identifying a resource allocation within a transmission bandwidth comprising a plurality of narrower bands; and
a processor configured to determine a transmission resource based on
the information,
a frequency shift added to the resource allocation, wherein the frequency shift comprises an integer number of the narrower bands; and
the transmission bandwidth,

wherein the transceiver circuit is further configured to receive, from the second communication apparatus, uplink data using the transmission resource.
