摘要： Methods, systems, and devices for indicating a modulation coding scheme (MCS) in LTE are described. A user equipment (UE) may receive downlink control information (DCI) from an evolved Node B (eNB) that includes an uplink grant of resources. The DCI may be configured and have a format that conveys an MCS table reference. The UE may identify the MCS table reference and, based on the reference, identify a legacy MCS table or a non-legacy MCS table. The legacy MCS table may be associated with quadrature amplitude modulation (QAM) up to a first order, and the non-legacy MCS table may be associated with QAM up to a second order, the second order being higher than the first order. The UE may modulate and code information for uplink transmissions using the identified MCS table.

摘要： Systems and methods for ACM trajectory include receiving data at a communications receiver; decoding the received data based on a selected MODCOD; monitoring a number of iterations used to decode the data using the selected MODCOD; comparing the number of iterations used to decode the data using the first selected MODCOD to a reference number of iterations; and adjusting a SNR threshold value for the selected MODCOD where the number of iterations used to decode the data using the first selected MODCOD is greater than the reference number of iterations.

摘要： Method for facilitating communication of control information. A message (200) is defined to communicate control information. The message (200) comprises a sequence of bits (201). A first mapping (202) defines how to interpret the message (200), defining which bits comprise a value of a first set of values (203), and for which variable in a first set of control information variables (204). The first communication device communication device (101) obtains (301) an update on how to interpret the message (200). The update is based on a second mapping (401). The second mapping (401) defines which bits in the sequence comprise a value of the second set of values (402), and for which variable. The first communication device (101) initiates (302) sending of an indicator of said update to a second communication device (102). The message (200) is devoid of the indicator or an indication of any of the first and second mapping (401).

摘要： Various aspects of the disclosure relate to limits for modulation and coding scheme (MCS) values. For example, a first set of limits (e.g., minimum and maximum limits) may be used for a first MCS table and a second set of limits may be used for a second MCS table. The disclosure also relates in some aspects to inter-device signaling that indicates which minimum and maximum limits for an MCS table are to be used for communication between the devices.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may determine channel state information (CSI) feedback based at least in part on a channel quality information (CQI) table and a CSI reference resource size of the apparatus, wherein at least one of the CSI feedback or the CQI table is modified based at least in part on a modulation configuration of the apparatus; and report the CSI feedback. Numerous other aspects are provided.

摘要： Methods, systems, and devices for modulation and coding scheme selection and configuration. A mobile communication device includes a table component, a table selection component, and a communication component. The table component is configured to maintain two or more tables each having entries for a plurality of available modulation schemes. The two or more tables include a default table and a secondary table. The default table and the secondary table have a matching number of entries, and the secondary table includes an entry corresponding to a 256-QAM scheme. The table selection component is configured to select a selected table from one of the default table and the secondary table. The communication component is configured to receive and process a communication from a base station based on a modulation and coding scheme of the selected table.

摘要： A modulation coding scheme (MCS) is selected i) from a first set of MCSs when the PHY data unit is to be transmitted using a first channel bandwidth, and ii) from a second set of MCSs when the PHY data unit is to be transmitted using a second channel bandwidth. The first set of MCSs corresponds to i) a number of spatial streams, and ii) the first channel bandwidth, the second set of MCSs corresponds to i) the number of spatial streams, and ii) the second channel bandwidth. The second set of MCSs excludes one or more MCSs in the first set of MCSs that will result in a padding-related constraint not being met when the second channel bandwidth is to be used. Information bits are encoded according to the selected MCS, and modulated according to the selected MCS.

摘要： A phase-locked loop (PLL) filter of a read channel includes a filter portion having an input coupled to delay circuitry having an output. The input of the filter portion is configured to receive a phase error signal. A look-up table is coupled to the filter portion. The look-up table comprises phase coefficients and frequency coefficients associated with a plurality of phase error magnitudes. The look-up table is configured to provide one or both of a selected phase coefficient and a selected frequency coefficient based on a magnitude of the phase error signal. The PLL filter is configured to adjust a bandwidth of the filter portion using one or both of the selected phase coefficient and the selected frequency coefficient. A phase signal indicative of estimated phase disturbance is produced at the output of the delay circuitry.
