摘要:
The present invention provides a method of windowing signals in a communication system. The method includes accessing at least one first signal associated with at least one of a plurality of orthogonal frequencies and applying a window function to the at least one first signal to form at least one second signal. The at least one second signal remains substantially orthogonal to signals associated with the plurality of orthogonal frequencies.

The present invention provides a method for detecting a reverse rate indicator channel. The method may include accessing first encoded information indicative of a data rate and a first sub-packet identifier associated with a sub-packet, accessing second encoded information indicative of the data rate and a second sub-packet identifier associated with the sub-packet, and modifying the second encoded information. The method may also include combining the first encoded information and the modified second encoded information, and decoding the combined first and modified second encoded information.

A method and apparatus for scheduling packets in an orthogonal frequency division multiple access (OFDMA) system is provided. More particularly, the presently described embodiments relate to a scheduling system whereby packets are prioritized based on packet delay information. The system also handles poor geometry users in an improved manner.

摘要:
Spatial discrimination information is fed back at both the multi-antenna transmitter and the multi-antenna receiver connecting a UE and cells within a CoMP measurement set. With the UE feeding back the transmitter and the receiver side spatial discrimination information of each cell-to-UE connection, the composite spatial CSI over multiple sites/nodes can be determined. The approach is applicable for UEs with single or multiple receiving antennas, and the spatial discrimination information can be wideband long-term or subband short-term. In some embodiments, the spatial discrimination information at the receiver side is derived from the actual spatial channel while receiver implementation is taken into account. The spatial discrimination information at the transmitter and at the receiver can be fed back using codebooks for MIMO precoding.
