Abstract
Certain aspects of the present disclosure relate to a technique for selecting modulation coding schemes (MCS). In some aspects, the MCS is selected based on a characteristic of an electronic device and the MCS of a transmitter. In some aspects, the MCS is selected based on a power imbalance between an access point and a user terminal.

A method for communicating in a wireless network by an electronic device, the method comprising:
- receiving data identifying a first modulation coding scheme from a transmitter;
- and
- selecting a second modulation coding scheme based on a characteristic of the electronic device including the first modulation coding scheme, wherein information identifying the second modulation coding scheme is a predetermined numerical N quantity lower than the first modulation coding scheme, the second modulation coding scheme being a function of a power imbalance between the transmitter and the electronic device independent of actual transmit powers of the transmitter and the electronic device;
- and
- transmitting data identifying the second modulation coding scheme.
An apparatus for communicating in a wireless network by an electronic device comprising:
- a transceiver configured to receive data identifying a first modulation coding scheme;
- a processing system configured to select a second modulation coding scheme based on a characteristic of the electronic device including the first modulation coding scheme, wherein information identifying the second modulation coding scheme is a predetermined numerical N quantity lower than the first modulation coding scheme, the second modulation coding scheme being a function of a power imbalance between the transmitter and the electronic device independent of actual transmit powers of the transmitter and the electronic device;
- and
- wherein the transceiver is configured to transmit and/or receive data identifying the second modulation coding scheme.
An apparatus for communicating in a wireless network by an electronic device, comprising:
- means for receiving data identifying a first modulation coding scheme from a transmitter;
- means for selecting a second modulation coding scheme based on a characteristic of the electronic device including the first modulation coding scheme, wherein information identifying the second modulation coding is a predetermined numerical N quantity lower than the first modulation coding scheme, the second modulation coding scheme being a function of a power imbalance between the transmitter and the electronic device independent of actual transmit powers of the transmitter and the electronic device;
- and
- means for communicating using the second modulation coding scheme.
A non-transitory computer-readable medium comprising code that, when executed, causes an apparatus to:
- receive data identifying a first modulation coding scheme from a transmitter;
- select a second modulation coding scheme based on a characteristic of the electronic device including the first modulation coding scheme, wherein information identifying the second modulation coding is a predetermined numerical N quantity lower than the first modulation coding scheme, the second modulation coding scheme being a function of a power imbalance between the transmitter and the electronic device independent of actual transmit powers of the transmitter and the electronic device;
- and
- transmit data identifying the second modulation coding scheme.
