    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: A method for improving channel estimation in a wireless communication system is disclosed. A wireless signal that includes a plurality of multipath components is received. N channel estimates are then obtained, where N is any positive integer greater than one. Each channel estimate of the N channel estimates corresponds to a different multipath component of the plurality of multipath components. The effects of interference between the plurality of multipath components on the N channel estimates is then reduced.

    摘要: Techniques for sending signaling information are described. Multiple signaling channels may be available to send signaling information. Different signaling information, different signaling parameter values, or different interpretations of signaling parameter values may be associated with different signaling channels and conveyed by the selection of these signaling channels, which may be used for actual transmission of remaining signaling information. A transmitter selects at least one signaling channel from among the multiple signaling channels based on first signaling information and sends second signaling information on the selected signaling channel(s) to convey the first and second signaling information. The transmitter sends at least one data stream on at least one data channel in accordance with the first and second signaling information. A receiver obtains the first signaling information based on the selected signaling channel(s) and decodes the selected signaling channel(s) to obtain the second signaling information. The receiver processes the data channel(s) in accordance with the first and second signaling information to recover the data stream(s).

    摘要: Techniques for determining valid (i.e., supported) TFCs from among all configured TFCs for normal and compressed modes. These techniques maintain sufficient historical information such that “TFC qualification” may be accurately performed. In a first scheme, Tx_power_requirement states are maintained for different combinations of each TFC. One combination is applicable for each TFC at each TFC interval, and valid TFCs are determined from applicable combinations in the proper state(s). In a second scheme, two Tx_power_requirement states are maintained for each TFC for the normal and compressed modes. In a third scheme, a single Tx_power_requirement state is maintained for each TFC for both modes based on a particular relative power requirement. In a fourth scheme, Tx_power_requirement states are maintained for a set of relative “bins” that cover the total range of required transmit power for all TFCs. And in a fifth scheme, a set of relative power requirement thresholds are maintained.

    摘要: Techniques for transmitting data in a manner to support multi-user scheduling, multiple-input multiple-output (MIMO) transmission, and interference cancellation are described. A base station assigns multiple time segments of a transmission time interval (TTI) to at least one terminal, maps data for each terminal to at least one time segment assigned to the terminal, and spreads the data in each time segment with at least one channelization code used in the TTI. A terminal receives an assignment of at least one time segment from among multiple time segments of the TTI, obtains input samples for the at least one time segment, and despreads the input samples with the at least one channelization code used in the TTI.
