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.

摘要： One or more relay stations may be employed along a wireless communication access path between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add scheduling information to the PDUs before they are delivered to the downstream intermediate relay stations or egress stations. The scheduling information is used by the downstream stations to schedule the PDUs for further delivery. The scheduling information may also be used by the egress station to schedule the PDUs for delivery. The scheduling information added to the PDU by the ingress station bears on a QoS class associated with the PDU, a deadline for the egress station to deliver the PDU, or a combination thereof.

摘要： A new method of performing interference estimation to allow the data packets to be efficiently delivered in an OFDM system. The interference estimation is performed on average over each frame for each mobile station individually in both frequency and time domains. Based on the estimated interference, the CIR can be determined by the BTS based on channel response estimates made by the BTS, or by the MS based on channel response estimates made for the uplink assuming a symmetrical channel. Numerical results show that the CIR estimation error could be very small if a sub-channel is considered as the minimum transmission unit. In terms of the aggregate throughput, the interference estimation method can provide a significant gain.
摘要翻译：一种执行干扰估计以允许在OFDM系统中有效地传送数据分组的新方法。对于每个移动台，在频域和时域中分别对每个帧平均执行干扰估计。基于估计的干扰，可以由BTS基于由BTS做出的信道响应估计来确定CIR，或者基于对假设对称信道的针对上行链路的信道响应估计由MS确定CIR。数值结果表明，如果将子信道视为最小传输单元，则CIR估计误差可能非常小。在总吞吐量方面，干扰估计方法可以提供显着的增益。
