Abstract

A method that allocates uplink shared channel resources includes acquiring the volume of data-to-be-transmitted and an uplink channel quality indication. The method further includes, based on the volume of data-to-be-transmitted acquired, determining a set of resource profiles of the uplink channel quality indication and a resource number. The method further includes judging whether or not the uplink channel quality indication comprised within the set of resource profiles is identical to the uplink channel quality indication acquired. If they are identical, using a corresponding set of resource profiles as a final resource profile; and if they are different, combining an uplink transmission power with the corresponding set of resource profile to determine the final resource profile. Under the premise of ensuring QoS, the method allows for minimization of transmission power of each terminal, thus reducing inter-system interference, allowing system performance to be further improved.

First claim

The invention claimed is:

1. A method of receiving data transmitted from a user equipment at a base station via an uplink shared channel, comprising:
acquiring a volume of data to be transmitted and a user equipment uplink channel quality indication from the user equipment;
based on the acquired volume of data to be transmitted, determining a set of resource profiles, each having an uplink channel quality indication and a resource number, by:
determining a resource profile code corresponding to the acquired volume of data to be transmitted according to a mapping relationship between volume of data-carried and resource profile code, each resource profile code corresponding to one set of resource profiles; and
calculating the set of resource profiles from the resource profile code using a conversion formula that is: resource profile code=uplink channel quality indication×weight factor 1+resource number×weight factor 2, where one of weight factor 1 and weight factor 2 is set based on a bandwidth uplink shared channel and the other weight factor is set to 1;

judging whether or not the uplink channel quality indication comprised within one of the set of resource profiles is identical to the user equipment uplink channel quality indication, and when one is identical, using the one of the set of resource profiles as a final resource profile, and when none are identical:
combining an uplink transmission power with the set of resource profiles to determine the final resource profile by:
selecting resource profiles from the set of resource profiles that meet a requirement that their uplink channel quality indications are smaller than the user equipment uplink channel quality indication;
when multiple sets of resource profiles meet the requirement, calculating the uplink transmission power of each set of resource profiles respectively, and selecting the resource profile of minimum uplink transmission power as the final resource profile; and
when only one resource profile meets the requirement, using that resource profile as the final resource profile; and

receiving data transmitted from the user equipment at the base station via the uplink shared channel based on the final resource profile.

2. The method according to claim 1 , wherein combining the uplink transmission power with the set of resource profiles further comprises:
when no resource profile in the set of resource profiles meets the requirement, determining the resource number corresponding to the acquired volume of data to be transmitted according to a mapping relationship among volume of data-carried, uplink channel quality indication, and
resource number, and combing the determined resource number with the user equipment uplink channel quality indication to generate the final resource profile.

3. The method according to claim 1 , wherein determining the resource profile code further includes:
looking up a minimum volume of data-carried equal to or greater than the acquired volume of data to be transmitted based on the mapping relationship between the volume of data-carried and resource profile code, and
selecting a resource profile code corresponding to the minimum volume of data-carried as the resource profile code.

4. A base station for receiving data transmitted from a user equipment via an uplink shared channel, the base station comprising: a resource allocator configured to:
acquire a volume of data to be transmitted and a user equipment uplink channel quality indication from the user equipment;
based on the acquired volume of data to be transmitted, determine a set of resource profiles, each having an uplink channel quality indication and a resource number, by:
determining a resource profile code corresponding to the acquired volume of data to be transmitted based on a mapping relationship between volume of data-carried and resource profile code, each resource profile code corresponding to one set of resource profiles; and
calculating the set of resource profiles from the resource profile code using a conversion formula that is: resource profile code=uplink channel quality indication×weight factor 1+resource number×weight factor 2, where one of weight factor 1 and weight factor 2 is set based on a bandwidth uplink shared channel and the other weight factor is set to 1;
judge whether or not the uplink channel quality indication comprised within one of the set of resource profiles is identical to the user equipment uplink channel quality indication, and when one is identical, use the one of the set of resource profiles as a final resource profile, and when none are identical:
combine an uplink transmission power with the set of resource profiles to determine the final resource profile by:
selecting resource profiles from the set of resource profiles that meet a requirement that their uplink channel quality indications are smaller than the user equipment uplink channel quality indication;
when multiple sets of resource profiles meet the requirement, calculating the uplink transmission power of each set of resource profiles respectively, and selecting the resource profile of minimum uplink transmission power as the final resource profile; and
when only one set of resource profiles meets the requirement, using that resource profile as the final resource profile; and

a receiver that receives data transmitted from the user equipment via the uplink shared channel based on the final resource profile.

5. The base station according to claim 4 , wherein the resource allocator is further configured to, in combining the uplink transmission power with the set of resource profiles:
when no resource profile in the set of resource profiles meets the requirement, determine the resource number corresponding to the acquired volume of data to be transmitted according to a mapping relationship among volume of data-carried, uplink channel quality indication, and resource number, and combine the resource number with the user equipment uplink channel quality indication to generate the final resource profile.

6. The base station according to claim 4 , wherein the resource allocator is further configured to, in determining the resource profile code:
look up a minimum volume of data-carried equal to or greater than the acquired volume of data to be transmitted based on the mapping relationship between the volume of data-carried and resource profile code, and
select a resource profile code corresponding to the minimum volume of data-carried as the resource profile code.

7. A communication system having a terminal in communication with a base station via an uplink shared channel, the communication system comprising:
the base station, which is configured to:
acquire a volume of data to be transmitted and a terminal uplink channel quality indication from the terminal;
based on the acquired volume of data to be transmitted, determine a set of resource profiles, each having an uplink channel quality indication and a resource number, by:
determining a resource profile code corresponding to the acquired volume of data to be transmitted based on a mapping relationship between volume of data-carried and resource profile code, each resource profile code corresponding to one set of resource profiles; and
calculating the set of resource profiles from the resource profile code using a conversion formula that is: resource profile code=uplink channel quality indication×weight factor 1+resource number×weight factor 2, where one of weight factor 1 and weight factor 2 is set based on a bandwidth uplink shared channel and the other weight factor is set to 1;

judge whether or not the uplink channel quality indication comprised within one of the set of resource profiles is identical to the terminal uplink channel quality indication
