    摘要: A subcarrier allocation method for use by a transmitter, the transmitter being configured to, when transmitting first and second data streams, allocate pilot symbols for the first and second data streams to subcarriers, such that a first plurality of subcarriers carry the pilot symbols for the first data stream and a second plurality of subcarriers carry the pilot symbols for the second data stream. The method includes allocating, when the transmitter transmits the first data stream but does not transmit the second data stream, the second plurality of subcarriers to carry no formation or information relating to the first data stream.

    摘要: A wireless communication method implemented in a communication system may include receiving a data sequence to be permuted, and obtaining information associated with the data sequence to be permuted, the information containing at least a length of the data sequence and a sampling spacing for permuting the data sequence. The method may also include identifying a first portion of the data sequence having a first number of adjacent data items, and a second portion of the data sequence having a second number of adjacent data items. The method may also include accessing the first number of data items from the first portion at the sampling spacing, and placing the accessed first number of data items into a predetermined number of sub-blocks included within a permuted data sequence to be generated based on the received data sequence. The method may further include inserting each of the second number of data items into an end position of one of the sub-blocks within the permuted data sequence, and outputting the permuted data sequence.

    摘要: A method for data transmissions in a wireless communication system includes: allocating resources for data to be transmitted; providing a seed number from the communication system; setting, based on the seed number, at least one parameter for a pseudo-random mapper having an input variable and an output variable; initializing an array with a number of base elements; increasing a current value of the input variable by a current value of a counter; and calculating a value of the output variable based on the pseudo-random mapper and the increased value of the input variable. The method further includes: swapping a first base element and a second base element in the array, the first base element being identified based on the current value of the counter, and the second base element being identified based on the value of the output variable; performing permutation on the resources by using the array as a permutation sequence; and transmitting the data.

The method further includes outputting the permuted second data sequence.
