发明名称 System and method for spatial multiplexing-based multiple antenna broadcast/multicast transmission
摘要 Methods and devices are provided for implementing two types of sub-channel arrangements. A first type of sub-channel arrangement involves defining a first traffic portion and a second traffic portion of a transmission resource, transmitting broadcast traffic on at least one first antenna of a plurality of antennas in the first traffic portion using a first sub-channelization, transmitting multicast traffic on at least one second antenna of the plurality of antennas, the at least one second antenna being distinct from the at least one first antenna, in the first traffic portion using a second sub-channelization, and transmitting unicast traffic on at least one antenna of the plurality of antennas in the second traffic portion using a third sub-channelization. A second type of sub-channel arrangement involves defining a first traffic portion and a second traffic portion, wherein for a portion of the transmission resource, a portion of the first traffic portion overlaps with a portion of the second traffic portion. In the portion of the transmission resource in which a portion of the first traffic portion overlaps with a portion of the second traffic portion, the channel arrangement involves transmitting broadcast/multicast traffic on at least one first antenna of a plurality of antennas using a first sub-channelization and b) transmitting unicast traffic on at least one second antenna of the plurality of antennas, the at least one second antenna being distinct from the at least one first antenna, using a second sub-channelization. The first, second and third sub-channelizations may be based on either one of or a combination of FDM sub-channelization and TDM sub-channelization.

主权项 1. A method in a multiple antenna transmitter comprising: for a transmission resource comprising a frequency component or a time component used by the multiple antenna transmitter: defining a first traffic portion and a second traffic portion of the transmission resource;identifying a portion of the transmission resource where the first traffic portion overlaps with the second traffic portion;in the portion of the transmission resource in which the first traffic portion overlaps with the second traffic portion; a) transmitting broadcast/multicast traffic on at least one first antenna of a plurality of antennas using a first sub-channelization based on either one of or a combination of FDM (frequency division multiplexing) sub-channelization and TDM (time division multiplexing) sub-channelization; andb) transmitting unicast traffic on at least one second antenna of the plurality of antennas, the at least one second antenna being distinct from the at least one first antenna, using a second sub-channelization based on either one of or a combination of FDM sub-channelization and TDM sub-channelization.
