    摘要： Devices, systems, methods and/or computer program products are provided to facilitate coordinated multipoint transmission and reception of communications in a wireless network. In some scenarios, different set of resources are allocated for uplink transmissions of multiple user equipment. In other scenarios collision avoidance and/or multiplexing techniques are used to enable reception and decoding of multiple uplink transmissions on the same or overlapping resources at the same time. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the disclosed subject matter. Therefore, it is to be understood that it should not be used to interpret or limit the scope or the meaning of the claims.

    摘要： In wireless communications, adaptive gain control may be performed by scaling of signals before and after a transform. A received signal power may be non-causally scaled to a first level within a desired range before transforming the received signal. The scaled signal is transformed between a time domain to a frequency domain and then its power is again non-causally scaled based on the first level. A feed forward circuit may be used in the power scaling. Different portions of the signal may be power adjusted independently of other portions. The different portions may be separated on a per-channel basis. Power scaling may be done on a symbol-by-symbol basis.

    摘要： Systems and methodologies are described that facilitate interleaving encoded control channel information for transmission over an uplink channel. The encoded control channel information, for example, can include encoded Channel Quality Indicator (CQI) information, encoded Precoding Matrix Indicator (PMI) information, and/or Rank Indicator (RI) information. CQI information, PMI information, and/or RI information can be encoded at an access terminal, for instance, by applying a punctured Reed Muller block code to generate a sequence of encoded bits. The encoded bits can be interleaved to reorder the sequence utilizing one or more interleaving approaches. Examples of interleaving approaches that can be leveraged include prime number based interleaving, generalized bit reversal interleaving, column-row interleaving with column bit reversal, and/or M-sequence based interleaving. Further, the reordered sequence of encoded bits can be transmitted to a base station over an uplink channel.

    摘要： A wireless communications method is provided. The method includes providing a multi-codeword transmission that includes ACK/NACK and discontinuous transmission (DTX) information. The method also includes ordering reference signal (RS) symbols in proximity to at least one other reference signal symbol to facilitate signaling of additional states and enabling spreading gain to be increased.
