Method and communication device for assigning scheduling grant

摘要

The present invention discloses a method and a communication device for assigning a scheduling grant. The method for assigning a scheduling grant includes: receiving a grant value, an E-TFCI offset value, and a data stream identifier corresponding to the E-TFCI offset value, where the E-TFCI offset value is determined by the Node B according to data transmitted by a mobile terminal through two data streams; determining, according to the grant value, a transport block size of the data stream identified by the data stream identifier in a current TTI; and determining a transport block size of the other data stream in the current TTI according to the transport block size and the E-TFCI offset value. in the embodiments of the present invention the MIMO technology may be applied to the HSUPA technology.

1. A method for assigning a scheduling grant, comprising:
receiving a grant value, an enhanced dedicated transport channel transport format combination indication (E-TFCI) offset value, and a data stream identifier corresponding to the E-TFCI offset value, wherein the grant value, the E-TFCI offset value, and the data stream identifier are returned by a Node B, and wherein the E-TFCI offset value is determined by the Node B according to data transmitted by a User Equipment through two data streams; setting transport block sizes for the two data streams in accordance with the E-TFCI offset value such that the two data streams exhibit similar demodulation performance, wherein setting the transport block sizes comprises determining a first transport block size for carrying a first data stream in a current transport time interval (TTI) according to the grant value, and determining a second transport block size for carrying a second data stream in the TTI according to the first transport block size and the E-TFCI offset value; and communicating, over the TTI, the first data stream using the first transport block size and the second data stream using the second transport block size, wherein the first data stream and the second data stream exhibit similar demodulation performance by virtue of a difference in transport block sizes specified by the E-TFCI offset value.
