    摘要: Aspects of the invention are directed to a transmit diversity method for use in a wireless terminal having a plurality of antennas and a wireless terminal configured to implement the method. The transmit diversity method includes using a different orthogonal sequence for each antenna, or group of antennas, for transmitting an uplink control channel from a wireless terminal to a base station. A first step of the method involves assigning at least one orthogonal sequence to one or more of the plurality of antennas, each of the plurality of antennas being assigned at least one orthogonal sequence. Once the orthogonal sequence is assigned, a further step involves scrambling a signal to be transmitted on the physical uplink control channel (PUCCH) using the at least one orthogonal sequence for each antenna thereby producing a scrambled PUCCH for transmission by each antenna. The scrambled PUCCH can then be transmitted on the plurality of antennas.

    摘要: To feedback MIMO channel conditions, a codeword from a codebook is selected. To reduce signalling, the codewords are organized into codeword subsets. The receiver signals an index of a codeword into a current 5 codeword subset previously made known to the transmitter. The current codeword subset is adaptively selected based on a threshold criterion. For example, if the best codeword from the current codeword subset is not sufficiently similar to the best codeword in the full codebook, a switch in the codeword subset is made.

    摘要: In a wireless communication system, a base station assigns resources to mobile stations using indices. Each index is associated with an assignment schedule for assigning resources. Once the base station determines an assignment schedule to assign particular resources, it encodes the schedule into an index and transmits it. A mobile station receives the index and decodes it to recover the assignment schedule. Both the base station and the mobile station may use look-up tables and/or algorithms for storing or generating indices associated with assignment schedules. To assign resources so as to indicate transmission characteristics over the resources, the base station transmits assignment blocks. Each assignment block indicates original transmission, retransmission, persistent assignment, non-persistent assignment, HARQ signaling, RAS-HARQ signaling, DRCH assignment, and/or LRCH assignment.
