Patent ID: 11336328

Abstract:
According to aspects of the disclosure, there is provided a method for a UE to select or be assigned or configured with a spreading sequence that is based on one or more communication parameters such as receiver type, receiver capability, SE, TBS, MCS, traffic load, PAPR requirement, MCL, number of layers, overloading, reliability requirement, transmission power consumption, number of active UEs, and transmission latency constraint, etc. In some embodiments, the spreading sequence may be related to a performance metric associated with an above parameter (PAPR, BLER, etc.). In some embodiments, this is achieved by associating spreading sequences with parameters or performance metrics, or both. In some instances the spreading sequences may be arranged or ordered in a manner to reduce signaling overhead (e.g., signaling an index is more efficient than signaling a value of a metric, and ordering correlates the index to the value).
