Abstract
Techniques pertaining to enhanced long range (ELR) communication schemes in wireless communications are described. An apparatus (e.g., a station (STA)) performs an ELR communication by either: (i) transmitting an ELR physical-layer protocol data unit (PPDU); or (ii) receiving the ELR PPDU. The ELR PPDU includes a spoofing preamble, an ELR preamble and an ELR data portion.
Claims19
A method, comprising:
- performing, by a processor of an apparatus, an enhanced long range (ELR) communication by either:
- transmitting an ELR physical-layer protocol data unit (PPDU);
- or
- receiving the ELR PPDU,
- wherein the ELR PPDU comprises a spoofing preamble, an ELR preamble and an ELR data portion,
- wherein the spoofing preamble comprises a legacy short training field (L-STF), a legacy long training field (L-LTF) and a legacy signaling (L-SIG) field,
- wherein the ELR preamble comprises an ELR signature sequence, an ELR short training field (ELR-STF), an ELR long training field (ELR-LTF) and an ELR signaling (ELR-SIG) field,
- wherein the ELR data portion carries data to be transmitted to one or more users, and
- wherein the ELR signature sequence is a physical-layer sequence associated with training and indicates whether the ELR preamble and the ELR data portion are in a one-spatial-stream format or in a two-spatial-stream format.

An apparatus, comprising:
- a transceiver configured to communicate wirelessly;
- and
- a processor coupled to the transceiver and configured to perform, via the transceiver, an enhanced long range (ELR) communication by either:
- transmitting an ELR physical-layer protocol data unit (PPDU);
- or
- receiving the ELR PPDU,
- wherein the ELR PPDU comprises a spoofing preamble, an ELR preamble and an ELR data portion,
- wherein the spoofing preamble comprises a legacy short training field (L-STF), a legacy long training field (L-LTF) and a legacy signaling (L-SIG) field,
- wherein the ELR preamble comprises an ELR signature sequence, an ELR short training field (ELR-STF), an ELR long training field (ELR-LTF) and an ELR signaling (ELR-SIG) field,
- wherein the ELR data portion carries data to be transmitted to one or more users, and
- wherein the ELR signature sequence is a physical-layer sequence associated with training and indicates whether the ELR preamble and the ELR data portion are in a one-spatial-stream format or in a two-spatial-stream format.
