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： Techniques for sending control information in a wireless communication system are described. In an aspect, a user equipment (UE) may send data for control information in a resource block with frequency division multiplexing (FDM) and may send pilot in the resource block with frequency-domain code division multiplexing (CDM). The UE may determine multiple groups of subcarriers to use to send data in multiple symbol periods of the resource block based on a predetermined pattern or a pseudo-random hopping pattern. Each group may include consecutive subcarriers to support localized FDM. The multiple groups may include different subcarriers to provide frequency diversity and possibly interference averaging. The UE may send modulation symbols for data (e.g., in the time domain) on the multiple groups of subcarriers in the multiple symbol periods. The UE may send a reference signal sequence for pilot on multiple subcarriers in each symbol period for pilot.

摘要： In an aspect, a method assists with blind decoding of uplink control signals on a Physical Uplink Shared Channel (PUSCH) and Physical Uplink Control Channel (PUCCH). The method assists in determining the uplink control path in the event a user equipment (UE) misses an uplink grant and blind decoding occurs. It is determined whether an uplink acknowledgement, rank indicator, and/or channel quality indicator are found on a PUSCH. If not, it is determined whether a scheduling request is expected and whether special handling for the scheduling request is indicated. Depending on those determinations, and whether any decoding attempts for uplink signals are successful, either the PUSCH or PUCCH is selected as the uplink control path.

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： Techniques for sending control information in a wireless communication system are described. In one design, a user equipment (UE) may map first information (e.g., CQI information) to M most significant bits (MSBs) of a message and may map second information (e.g., ACK information) to N least significant bits (LSBs) of the message if the second information is sent, where M≧1 and N≧1. The UE may encode the message with a block code, e.g., encode the M MSBs with the first M basis sequences of the block code and encode the N LSBs with the next N basis sequences of the block code. The second information may include N ACK bits. The UE may set each ACK bit to a first value for an ACK or to a second value for a NACK. The second value may also be used for discontinuous transmission (DTX) of ACK information.
