Abstract
Embodiments of a method and an apparatus for wireless communications are disclosed. In an embodiment, a method for wireless communications involves encoding bits in a Physical Layer Protocol Data Unit (PPDU) using a basic bandwidth that is smaller than a signal bandwidth, wherein the bits are duplicated within the PPDU, and transmitting the PPDU with duplicated bits in accordance with a power spectrum density (PSD) limit.
Claims22
A method for wireless communications, the method comprising:
- encoding bits in a Physical Layer Protocol Data Unit (PPDU) using a basic bandwidth that is smaller than a signal bandwidth, wherein the bits are duplicated within the PPDU;
- and
- transmitting the PPDU with the bits that are duplicated in accordance with a power spectrum density (PSD) limit, wherein an index in a modulation and coding scheme (MCS) field in the PPDU indicates the bits are duplicated, wherein the index identifies an MCS0-Dual Carrier Modulation (DCM) with 2 times Duplication (2×DUP) entry in an MCS table.
A wireless device, the wireless device comprising:
- a processor configured to:
- encode bits in a Physical Layer Protocol Data Unit (PPDU) using a basic bandwidth that is smaller than a signal bandwidth, wherein the bits are duplicated within the PPDU;
- and
- transmit the PPDU with the bits that are duplicated in accordance with a power spectrum density (PSD) limit, wherein an index in a modulation and coding scheme (MCS) field in the PPDU indicates the bits are duplicated, wherein the index identifies an MCS0-Dual Carrier Modulation (DCM) with 2 times Duplication (2×DUP) entry in an MCS table.
