Title:

ADAPTING A DIVERSITY TRANSMISSION MODE IN A WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO2005112328

Kind Code:

A3

Abstract:

A controller (102) in a fixed network of a wireless data communication system (100) transmits an indication that a diversity transmission of the information stream is available. When predetermined capabilities of a user equipment (112) and the fixed network are sufficient to allow soft combining of a primary transmission and the diversity transmission of bits of the information stream in the user equipment, the controller further transmits primary and diversity transmissions in a manner that facilitates soft combining in the user equipment, and transmits a group identity of the information stream to indicate that the information stream is in the primary and diversity transmissions.
