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.
摘要翻译：在无线通信中，可以通过缩放变换之前和之后的信号来执行自适应增益控制。在变换接收到的信号之前，接收到的信号功率可以在期望范围内被非因果地缩放到第一电平。缩放的信号在时域到频域之间变换，然后基于第一级再次非因果地缩放它的功率。可以在功率缩放中使用前馈电路。信号的不同部分可以独立于其它部分进行功率调节。可以在每个通道的基础上分离不同的部分。功率缩放可以在逐个符号的基础上进行。

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： Supporting communication on multiple carriers. A user equipment (UE) is configured with a base (anchor, regular, stand-alone) carrier and a dependent (extension) carrier linked (paired) to the base carrier. Data transmission on the dependent carrier is scheduled via a scheduling carrier, which is different from the dependent carrier. The UE receives (714) a scheduling grant on the scheduling carrier and determines whether the scheduling grant is for the base carrier and/ or the dependent carrier. The UE communicates (718), e.g. sends or receives data, on the base carrier and/or the dependent carrier based on the scheduling grant. The scheduling grant may be (i) a separate grant carrying scheduling information for only one carrier, (ii) a common grant carrying scheduling information for both carriers, (iii) a joint grant carrying separate scheduling information for each carrier, or (iv) a composite grant that may be a separate grant, a common grant, or a joint grant. A configuration of the base (anchor) carrier and a dependent (extension) carrier is received from the eNodeB at the UE.

摘要： Aspects describe channel estimation in an OFDM system. Baseline DFT-based channel estimation can be performed and scaling can be applied to mitigate distortion in the DFT-based estimations. In some aspects, baseline DFT-based channel estimation can be performed and tones for which DFT-based estimate is deemed unreliable can have MMSE based processing applied locally. If orthogonal sequence is deemed excessive, orthogonal sequence cancellation can be applied prior to the MMSE based processing.

摘要： In a wireless network (100) with HSDPA-enabled user equipment devices (130), the base transceiver station (120) transmits to each HSDPA-enabled UE information regarding allocation of HSDPA codes and associated modulation techniques for other HSDPA-enabled UEs. Using this additional control information, each UE configures decision feedback filter of its equalizer to reduce inter-user interference. The additional control information may be transmitted in a packet (300) that includes a CRC portion (310) with the packet's CRC masked by a common ID, which is known to the HSDPA-enabled UEs. To reduce the number of bits needed to transmit the additional control information, the HSDPA codes used with a particular modulation technique are allocated consecutively. For each modulation technique, only the beginning code and the total number of codes need be known to the UEs. The number of codes used with each modulation technique may be allowed to change once in several TTIs.

摘要： Techniques for transmitting data in a manner to facilitate equalization at a receiver are described. Guard intervals are appended to data blocks such that each data block has a guard interval at the beginning of the data block and a guard interval at the end of the data block. Each guard interval may be discontinuous transmission (DTX), a polyphase sequence, or some other known sequence. Pilot is appended to each set of at least one data block. The data blocks, pilot, and guard intervals may be sent using various slot structures and are processed for transmission. The processing may include mapping the data blocks to at least one physical channel, channelizing the data blocks for each physical channel with a channelization code, combining all physical channels, and scrambling the combined data, pilot, and guard intervals with a scrambling code.
