Embodiment Construction

[0034]Referring initially to FIG. 1, a radio communication system generally indicated at 10 forms a multi-user radio communication system allowing radio communication with mobile stations. Two exemplary mobile stations 12 are shown in the figure. In an exemplary implementation, the communication system forms a cellular communication system that generally operates in accordance with the operating protocols promulgated in the CDMA 2000 communication system supporting IxEV-DV data communication.

[0035] However, embodiments of the present invention may also be implemented in other types of communication systems where data communication traffic may be accomplished at selectable data rates and in communication systems utilizing HARQ feedback schemes. Therefore, although the following description will describe the exemplary operation of the embodiment of the present invention for the implementation of the embodiment of the present invention in a CDMA 2000 communication system suppo...

Abstract

Apparatus, and associated method, for facilitating reverse link scheduling in a CDMA 2000 communication system (Figure 1, 10) that provides for high data rate communication services, such as 1 xEV-DV communication services. Power control bits (Figure 1, 46) used to perform power control on the reverse link are punctured with rate grant control bits and HARQ indications. A power control bit puncturer (Figure 1, 48) punctures the power control bits with the rate grant control bits and HARQ indications. Physical layer signaling is thereby provided without the need to define additional control channels by which to perform the additional control operations.

Description

technical field [0001] The present invention generally relates to a manner of facilitating scheduling of data communications in a radio communications system, such as a CDMA 2000 communications system supporting 1xEV-DV data communications. More specifically, the present invention relates to an apparatus and associated method whereby rate selection commands and HARQ indications are provided as physical layer signaling to mobile stations or other communication stations operable in a radio communication system. [0002] Power control commands sent on existing channels are punctured using rate selection commands and HARQ indications. These commands and instructions are provided quickly because the signaling is performed on the physical layer. Backward compatibility with previous generation devices is also maintained. Background technique [0003] Transferring data using communication systems is a practical need of modern society. Data is communicated according to the executi...
