    • A method, device, computer program product, integrated circuit, and system are described to dispose pilot sequences (for aiding a receiver in estimating a channel) in a frame structure that has subframes of sub-carriers and symbol positions. Locations of common pilot sequences are predetermined, and includes 1) in each subframe, a pilot sequence is disposed in a first symbol position for each of at least two staggered sub-carriers, and 2) in at least one subframe, at least one pilot sequence is disposed in other than the first symbol position and in a sub-carrier other than any of the at least two staggered sub-carriers. Dedicated pilot sequences, whose locations in the frame are not predetermined, are disposed in response to an indication of channel quality received over a wireless link. Common pilot sequences may relate to one or two transmit antennas, and dedicated pilot sequences may enable addition of third and fourth transmit antennas.
    • 描述了一种方法,设备,计算机程序产品,集成电路和系统,以在具有子载波和符号位置的子帧的帧结构中配置导频序列(用于帮助接收机估计信道)。 公共导频序列的位置是预定的,并且包括1)在每个子帧中,导频序列被布置在至少两个交错子载波中的每一个的第一符号位置中,以及2)在至少一个子帧中,至少一个导频 序列被布置在除了第一符号位置之外且在除了至少两个交错子载波中的任何一个以外的子载波中。 响应于通过无线链路接收的信道质量的指示,设置其帧中的位置不是预定的专用导频序列。 公共导频序列可以涉及一个或两个发射天线,并且专用导频序列可以实现第三和第四发射天线的添加。

    • A first parameter such as an indicator of modulation and coding scheme MCS for a first shared channel SCH codeword and a second parameter for a second SCH codeword are determined. From a locally stored mapping rule a bit sequence that explicitly indicates the first parameter and that implicitly indicates the second parameter is chosen, and a first control channel CCH codeword is transmitted with the explicit bit sequence that explicitly indicates the first parameter for the first SCH codeword and a second CCH codeword is sent companion to the first CCH codeword, wherein the second parameter for the second SCH codeword is implicitly indicated by the explicit bit sequence of the first CCH codeword. The receiving party determines the second parameter by its own locally stored mapping rule, and an indicator in each CCH codeword may be used to inform the receiver that the two (or more) CCH codewords are associated with one another and to use its mapping rule to determine the second parameter.
    • 确定第一参数,例如用于第一共享信道SCH码字的调制和编码方案MCS的指示符和用于第二SCH码字的第二参数的第一参数。 从本地存储的映射规则中,选择明确指示第一参数并隐式指示第二参数的位序列,并且以显式地指示第一SCH代码字的第一参数的显式位序列发送第一控制信道CCH码字 并且第二CCH码字被发送到第一CCH码字的伴随,其中第二SCH码字的第二参数由第一CCH码字的显式比特序列隐含地指示。 接收方通过其本地存储的映射规则来确定第二参数,并且每个CCH码字中的指示符可以用于通知接收机两个(或多个)CCH码字彼此相关联,并且使用其映射规则 确定第二个参数。
