Packet data transmission in a mimo system

A secondary station for use in a packet data transmission system having a primary station with a plurality of antennas, the secondary station comprising:

• signal transmitting and receiving means;
• a plurality of antennas;
• means for monitoring a radio environment of the packet data transmission system;
• and
• means for transmitting a signal including radio environment information, the radio environment information including at least one of a measured level of interference between pairs of transmitter and receiver antennas, a transfer function of channels between pairs of transmitter and receiver antennas, and a number of antennas at the secondary station;
• and
• means for configuring receiver resources of the secondary station, the receiver resources being configured for processing received data signals and interference by choosing, based on the radio environment information, selected ones of said plurality of antennas of the secondary station to receive interference signals for interference signal cancellation.

A packet data transmission system comprising:

• at least one secondary station having a plurality of antennas, the at least one secondary station comprising a processor being configured to:
• monitor a radio environment of the packet data transmission system;
• transmit a signal including radio environment information, the radio environment information including at least one of a measured level of interference between pairs of transmitter and receiver antennas, a transfer function of channels between pairs of transmitter and receiver antennas, or a number of antennas at the secondary station;
• and
• configure receiver resources of the secondary station to process received interference and data signals by choosing, based on the radio environment information, selected ones of antennas of the secondary station to receive interference signals for interference signal cancellation;
• and
• a primary station having a plurality of antennas, the primary station being configured to allocate transmission resources based on the radio environment information.

A secondary station for use in a packet data transmission system, the secondary station comprising:

• a plurality of antennas;
• and
• a processor coupled to the plurality of antennas, the processor being configured to:
• monitor a radio environment of the packet data transmission system;
• transmit a signal including radio environment information to a primary station, the radio environment information including at least one of a measured level of interference between pairs of transmitter and receiver antennas, a transfer function of channels between pairs of transmitter and receiver antennas, or a number of antennas at the secondary station;
• and
• choose, based at least partially on the radio environment information, selected ones of the plurality of antennas to receive interference signals for interference signal cancellation.

A primary station for use in a packet data transmission system, the primary station comprising:

• a plurality of antennas;
• and
• a processor coupled to the plurality of antennas, the processor being configured to:
• receive a signal including radio environment information from a secondary station, the radio environment information including at least one of a measured level of interference between pairs of transmitter and receiver antennas, a transfer function of channels between pairs of transmitter and receiver antennas, and a number of antennas at the secondary station;
• and
• allocate, based on the radio environment information, transmission resources of the plurality of antennas for transmission of communication signals to the secondary station such that the secondary station is enabled to choose, based on the radio environment information, selected ones of antennas of the secondary station to receive interference signals for interference signal cancellation.
