Abstract: A base station selects and assigns uplink segments to specific wireless terminals. The base station estimates potential system interference levels, selects, assigns, and transmits a maximum uplink rate indicator value to a wireless terminal indicating the maximum uplink data rate that the wireless terminal is permitted to use. The wireless terminal receives the maximum data rate indicator and selects an uplink data rate to use which is less than or equal to the maximum data rate indicator level. The selection includes consideration of data amounts, data importance, communications channel quality, changes affecting the channel and/or power information. The wireless terminal encodes information indicative of the selected used rate with the user data/information to be transmitted by placing additional energy on a subset of the uplink signals. The base station receives the uplink signals including user data/information and data rate. The base station extracts the data rate used and utilizes the data rate to demodulate and decode the uplink user data/information.

Abstract: Downlink traffic channel data rate options and methods of indicating to a wireless terminal a utilized downlink data rate option are described. The downlink traffic channel rate option for a segment is conveyed using an assignment signal and/or a block in the downlink traffic channel segment which is not used for user data. Downlink segment assignment signals in some implementations allocate fewer bits for rate option indication than are required to uniquely identify each option. In some implementations low rate options, e.g., using QPSK, are uniquely identified via assignment signals. Higher rate options, e.g., using QAM16 modulation, are conveyed via the distinct information block in the downlink traffic segment using a first coding/modulation method. Still higher rate options, e.g., using QAM16, QAM64, or QAM256, are conveyed via the information block in the segment using a second coding/modulation method which is applied to the rate option information.

Abstract: A method and a device for holding calls between networks are disclosed herein. The method includes: receiving a call hold request sent by a UE in a CS network, where the call hold request carries an indication that the UE in the CS network will continue sending media streams; and instructing a peer device to keep receiving the media streams from the UE in the CS network and stop sending the media streams. In the technical solution under the present invention, the UE in the CS network partially releases the radio resources after initiating the call hold operation, and therefore, the UE in the CS network can play local media files to the peer device after the call is held, thus saving network resources and improving the user experience.

Abstract: A base station selects a maximum rate option indicator value for an uplink communications segment, e.g., uplink traffic channel segment, and transmits the selected indicator value, e.g., as part of the assignment message. The maximum rate option indicator value indicates to the wireless terminal a maximum allowed data rate option that the wireless terminal is permitted to use for the corresponding assigned uplink communications segment, the wireless terminal determining the actual uplink rate option used. Each uplink data rate option corresponds to: a number of information bits to be communicated in an uplink communication segment, a coding rate, and a modulation method. Some embodiments include multiple types of maximum uplink rate option indicators, e.g., a first type using a single bit and a second type using at least three bits. Different modulation methods are, in some embodiments, used for communicating the different types of maximum uplink rate option indicators.

Abstract: A device includes a zero symbol rate (ZSR) coding/modulation module and a second type coding/modulation module. Both modules generate modulation symbols to be conveyed using the same air link resources but with the non-zero ZSR symbols having a higher power level. The ZSR module generates a mixture of zero and non-zero modulation symbols. A ZSR modulation scheme communicates information using both the position of the non-zero modulation symbols and the phase and/or amplitude of the non-zero modulation symbols. Different ZSR schemes, implementing different ratios relating the number of zero symbols to the total number of symbols, can be associated with different low data rates while second module modulation schemes can be associated with different high data rates. Modulation symbols from two modules are in some embodiments, superimposed. In some embodiments, non-zero ZSR modulation symbols punch out second module modulation symbols which occupy the same air link resource.

Abstract: The claimed subject matter relates to encoding and decoding information in a wireless communication system using soft-demodulation and interleaving of concatenated code received in a strip channel. A set of symbols is received containing a plurality of information bits, dividing the received set of symbols into a plurality of subsets of symbols, each subset corresponding to the input of an inner code demodulation selecting a set of initial a priori values of the inner code demodulation for each subset of symbols, and demodulating each subset of symbols, using the initial a priori values of the subset of symbols and an inner code generator matrix, to generate a plurality of first soft information values as the output of the inner code demodulation. Each of the first soft information values is associated to one of the plurality of information bits using an outer code generator matrix, calculating a plurality of second soft information values as the output of the outer code demodulation, wherein each second soft information value corresponds to one of the information bits and is calculated using at least two of the first soft information values associated with the information bit, determining a new set of a priori values of the inner code demodulation for each subset of symbols, using the second soft information values and the outer code generator matrix, and replacing the initial a priori values with the new a priori values, and repeating the demodulating, associating, calculating and determining actions at least once.

Abstract: A flexible and relatively hardware efficient LDPC decoder is described. The decoder can be implemented with a level of parallelism which is less than the full parallelism of the code structure used to control the decoding process. Each command of a relatively simple control code used to describe the code structure can be stored and executed multiple times to complete the decoding of a codeword. Different codeword lengths are supported using the same set of control code instructions but with the code being implemented a different number of times depending on the codeword length. The decoder can switch between decoding codewords of different lengths, without the need to change the stored code description information, by simply changing a code lifting factor that is indicative of codeword length and is used to control the decoding process. When decoding codewords shorter than the maximum supported codeword length some block storage locations may go unused.

Abstract: Methods and apparatus for scaling soft values as part of an error correction decoding process are described. Accurate decoding depends on use of the appropriate scale factor. Selection and use of the scale factor to scale soft values is designed to improve and/or optimize decoder performance without the need for prior knowledge of the correct scale factor or the actual channel conditions at the time the signal from which the soft values were obtained was transmitted through a communications channel. The techniques of the present invention assume that the soft values to be processed were transmitted through a communications channel having a quality that can be accurately described by a channel quality value. A scale factor is determined from the distribution of soft values to be scaled and an assumption that the channel through which they were transmitted was of the quality corresponding to a preselected channel quality value.
