Methods of allocating orthogonal resources of a wireless communication network to a user equipment (UE) that uses transmit diversity are disclosed. In one or more embodiments, the UE is configured to transmit a reference symbol and a modulated symbol on multiple orthogonal resources on an antenna. The method includes: selecting, by the UE, a first and a second orthogonal resource, respectively, from a plurality of orthogonal resources according to the state of information bits to be communicated by the UE; and transmitting, by the UE, the reference and data symbols on the first and the second orthogonal resource, respectively, on one antenna. The first and the second resource are different for at least one of the states of the information bits. The first and the second resource are both in the same physical resource block.

A method for providing transmit diversity in wireless network communications is presented. An indication of a slot structure is received. The slot structure identifies at least a first location of a reference signal within a slot. A first reference signal is transmitted within a first slot using a first antenna. A location of the first reference signal within the first slot is determined by the slot structure. A second reference signal is transmitted within the first slot using a second antenna. A location of the second reference signal within the first slot is determined by the slot structure. In some cases, the slot structure identifies a second location of a reference signal within the slot structure. The second location being offset from the first location, and a third reference signal is transmitted within the first slot at the second location on the first antenna.

A transmultiplexer (202) is provided for transmultiplexing digitized signal samples (244) produced by a converter. The transmultiplexer (202) comprises a first Fourier transformer bank (304) configured to transform the digital signal samples (244) produced by the digitizer into frequency domain input signals (320). The transmultiplexer (202) also comprises a frequency domain shifter bank (306) configured to circularly shift the frequency domain input signals (320) to produce shifted signals (324). A frequency domain pre-filter bank (308) is configured to perform a first fast convolution with the shifted signals (324) and a first discrete Fourier transform of a first filtering function to produce filtered input signals (330), and a combining Fourier transformer (310) is configured to transform the filtered input signals (330) to produce output signals (348) containing a sample corresponding to a down-converted channel.
摘要:
In a method for producing antenna element signals for transmitting a serial traffic channel from a plurality of elements in an antenna array, data in the serial traffic channel is converted to data in two or more parallel traffic channels. Thereafter, data in the two or more parallel traffic channels are spread with different spreading codes to produce spread traffic signals. The spread traffic signals are combined to produce combined signals, which are each modified according to adaptive array weights to produce element signals. A pilot signal is then added to at least one of the element signals to produce two or more antenna element signals.
