Abstract:
Received communication signals may be decoded according to a combined, iterative inner code -- outer code decoding technique. The inner code decoding is based on information produced by the outer code decoding.
Abstract:
The disclosure provides for an apparatus for wireless communications using carrier aggregation comprised of multiple carrier components. The apparatus can include a processor configured to generate one or more instances of a codeword from a data payload. In an aspect, the apparatus also includes a modulator configured to modulate the one or more instances of the codeword onto the multiple carrier components for transmission. In an aspect, the apparatus also includes a resource manager configured to provide the processor with a virtual carrier space comprising a logical carrier having a contiguous bandwidth equivalent to the aggregated bandwidth of the multiple carrier components. In an aspect, the process may be further configured to interleave at least one of the codeword instances across the multiple carrier components. In an aspect, the modulator may be configured to modulate the codeword instance onto the multiple carrier components in accordance to the interleaving.
Abstract:
Adaptive signaling (e.g., pilot signaling, control signaling, or data signaling) is disclosed in which resources allocated to one or more symbols are allowed to vary to more closely match channel conditions and data latency requirements. In one embodiment, a method includes determining that low-latency data is available to transmit during a first transmission time interval (TTI) and informing a mobile station that the low-latency data will be transmitted during one slot reserved for a symbol in the first TTI. The low-latency data may be transmitted during the first time slot in the first TTI and the symbol (originally scheduled symbols) may be transmitted during a second time slot.
Abstract:
Systems and techniques are disclosed to reduce pilot overhead by providing common reference signals coded with cover codes that are orthogonal in time and frequency domains. Common reference signals that are coded by cover codes orthogonal in both domains can be de-spread in both the time and frequency domains for improved resolution and larger pull-in windows. Semi-uniform pilot spacing in both the frequency and time domains can be utilized. In time domain, a first pilot symbol pair is spaced by a first time interval and a second pilot symbol pair is spaced by a second time interval from the first pair, the second interval being greater than the first. In frequency domain, a first set of pilot symbols is densely placed in a selected frequency band and a second set of pilot symbols is sparsely placed surrounding and including the selected frequency band.
