Dynamic cyclic prefix (CP) length in wireless communication
First Claim
1. A method of wireless communication by a node, the method comprising:
- receiving a dynamic indication configured to recommend at least one of cyclic prefix (CP) length or tone spacing from a scheduling entity;
determining at least one of a CP length or a tone spacing for a signal for a communication link based on the dynamic indication; and
communicating the signal utilizing the determined at least one of the CP length or the tone spacing, with the scheduling entity via the communication link.

Abstract
An apparatus may determine a cyclic prefix (CP) length for a signal for a communication link based on a dynamic indication. The CP length may be determined from a plurality of CP lengths. The apparatus may communicate the signal using the determined CP length. Determining the CP length may be further based on at least one of a modulation and coding scheme, a subcarrier spacing, a service type, a communication link direction, a rank number, a type or a capability of the node, or a number of nodes scheduled in the same transmit time interval. Determining the CP length may include determining a first CP length for a first symbol of a plurality of symbols in the TTI, and determining a second CP length, different than the first CP length, for a second symbol of the plurality of symbols in the TTI. Various additional and alternative aspects are described herein.
