1. A method of communication, comprising:
- receiving, by a near field communication (NFC) controller (NFCC), a protocol data unit (PDU) from a remote NFC endpoint;
determining whether the received PDU is a symmetry (SYMM) PDU or a link deactivation PDU, the SYMM PDU and the link deactivation PDU associated with a logical link control protocol (LLCP) link;
communicating the received PDU to a device host (DH) upon a determination that the received PDU is not a SYMM PDU or a link deactivation PDU; and
receiving, by the NFCC from the DH, a link timeout timer that defines a time duration that the NFCC waits for a PDU from the remote NFC endpoint prior to communicating a link failure message to the DH.

Abstract
Aspects disclosed herein relate to partitioning LLCP responsibilities between the NFCC and DH. In an example, with a NFC device a DH maybe configured to establish a LLCP link with a remote NFC endpoint through a NFCC, and partition LLCP related responsibilities between the DH and the NFCC when the NFCC is operable for LLCP split communications. Further, the NFCC may be operable to receive a PDU from a remote NFC endpoint, determine whether the received PDU is a SYMM PDU or a link deactivation PDU, and communicate the received PDU to a DH upon a determination that the received PDU is not a SYMM PDU or a link deactivation PDU.
