Link Adaptation In Grant-Free Multiple Access Systems |
摘要 |
A BS determines an amount of resource overloading for a contention transmission unit (CTU) access region associated with a grant-free uplink transmission scheme in a multiple access system. The BS determines a modulation and coding scheme (MCS) limit indicating a maximum MCS level for the CTU access region. The BS sends the MCS limit to a plurality of user equipments (UEs) associated with the first CTU access region. A UE receives from the base station the MCS limit and determines a first MCS index within the MCS limit for a first uplink transmission. The UE sends the first uplink transmission to the base station using a CTU in the CTU access region. The first uplink transmission includes user data and the first MCS index determined at the first UE. |

1. A method, comprising:
determining an amount of resource overloading for a contention transmission unit (CTU) access region associated with a grant-free uplink transmission scheme in a multiple access system; determining a modulation and coding scheme (MCS) limit indicating a maximum MCS level for the CTU access region based on the amount of resource overloading; and sending the MCS limit to a plurality of user equipments (UEs) associated with the CTU access region. |
