Abstract: The present disclosure relates to adaptive modulation and coding scheme selection and signaling in a communication system. In particular, a modulation and coding scheme to be used for transmission of a data is selected from a set of predetermined modulation and coding schemes. The predetermination of the set is performed by selecting the set from a plurality of predefined sets. The sets have the same size, so that a modulation and coding selection indicator signaled to select the modulation and coding scheme may be advantageously applied to any of the selected sets. Moreover, a second set includes schemes with a modulation not covered by the schemes of a first set, and which is of a higher order than any modulation in the first set.

Abstract: 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.

Abstract: 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.

Abstract: 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).

Abstract: 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.
