    摘要: The exemplary embodiments of this invention generally relate to message header-type notification that, for example, enables the co-existence of a legacy header type with one or more new header types on a same radio link. In one non-limiting, exemplary embodiment, a method includes: determining a type of medium access control (MAC) header to transmit in a MAC transmission; setting a value of a notification field in a resource allocation message based on the determined type of MAC header; and transmitting the resource allocation message. In another non-limiting, exemplary embodiment, a method includes: receiving a resource allocation message having a notification field; and using a value of the notification field to determine a type of medium access control (MAC) header for a MAC transmission.

    摘要: A transmitter determines a number of available bits (Navbits) in a minimum number of orthogonal frequency division multiplex (OFDM) symbols in which a data field of a packet may fit, by Navbits=(NCBPS*(1+USTBC))*ceil(Npld/(NCBPS*R*(1+USTBC))), where USTBC equals 1 when Space-Time Block Code (STBC) is used and 0 otherwise, where Npld=LENGTH*8+16, where NCBPS is the number of coded bits per symbol, where R is the code rate, and where LENGTH is a number of bytes in a Physical Layer Convergence Protocol (PLCP) PLCP Service Data Unit (PSDU); and determines an integer number of Low-Density Parity-Check Code (LDPCC) codewords to be transmitted, NCW, and the length of the codewords to be used, LLDPC, from information capable of being expressed in a table format.
