摘要： A method and an apparatus for preserving compatibility between legacy mode of operation and new mode of operation in a communication system, wherein allocation of resources is different in the legacy mode of operation and the new mode of operation is disclosed. Accordingly, an entity of a wireless access network, e.g., a base station, transmits signals comprising information about reallocation of resources from a legacy mode of operation to a new mode of operation. These signals are received at another entity of a wireless access network, e.g., a subscriber station, which then controls use by the subscriber station of resources allocated to the subscriber station in accordance with the information.

摘要： Techniques for transmitting data with dynamic space-time coding are described. Dynamic space-time coding refers to the mapping of data across both space and time dimensions based on a mapping scheme that changes in a dynamic manner, e.g., a time-variant manner. A transmitter generates at least one data stream and performs space-time coding on the at least one data stream in a dynamic manner to generate at least two output streams for transmission from at least two antennas. The space-time coding may be performed in various manners. For example, each data stream may be space-time coded based on a respective set of space-time codes, e.g., by cycling through the space-time codes in the code set or by using a space-time code selected based on feedback from a receiver. The code set for each data stream may also be selected from among multiple code sets available for the data stream.

摘要： Techniques for transmitting data with space-time scrambling in cellular systems (e.g., CDMA systems) are described. At least one stream of data symbols is generated, mapped to one or more physical channels, and spread with channelization codes for the physical channels. Space-time scrambling is performed on the at least one stream of data symbols to generate at least two streams of output chips. The space-time scrambling may be achieved by performing matrix multiplication with a sequence of matrices. For each time interval in which space-time scrambling is performed, a matrix may be selected (e.g., based on a scrambling code for a base station), and data to be sent in the time interval is multiplied with the selected matrix. The matrices used for space-time scrambling may be defined and selected in various manners. The streams of output chips are processed and transmitted from respective transmit antennas.
