Abstract
A method of adjusting the modulation and coding scheme for uplink channel power control in advanced telecommunication networks includes receiving an indication of a power adjustment mode for an uplink multiple-input multiple-output (MIMO) transmission. The power of the uplink MIMO transmission is adjusted according to the received power adjustment mode.
Claims26
A method of wireless communication, comprising:
- receiving an indication of a power adjustment mode for an uplink multiple-input multiple-output (MIMO) transmission, the indication further indicating at least one uplink channel processing stage for implementing the power adjustment, the at least one uplink channel processing stage comprising one or more of a first stage after precoding, a second stage after layer mapping and prior to the precoding, a third stage before the layer mapping, or a combination thereof;
- and
- adjusting power of the uplink MIMO transmission at the at least one indicated uplink channel processing stage and according to the power adjustment mode.
An apparatus for wireless communication, comprising:
- means for receiving an indication of a power adjustment mode for an uplink multiple-input multiple-output (MIMO) transmission, the indication further indicating at least one uplink channel processing stage for implementing the power adjustment, the at least one uplink channel processing stage comprising one or more of a first stage after precoding, a second stage after layer mapping and prior to the precoding, a third stage before the layer mapping, or a combination thereof;
- and
- means for adjusting power of the uplink MIMO transmission at the at least one indicated uplink channel processing stage and according to the power adjustment mode.
A computer program product for wireless communication in a wireless network, comprising:
- a non-transitory computer-readable medium having program code recorded thereon, the program code being executed by a processor, and the program code comprising:
- program code to receive an indication of a power adjustment mode for an uplink multiple-input multiple-output (MIMO) transmission, the indication further indicating at least one uplink channel processing stage for implementing the power adjustment, the at least one uplink channel processing stage comprising one or more of a first stage after precoding, a second stage after layer mapping and prior to the precoding, a third stage before the layer mapping, or a combination thereof;
- and
- program code to adjust power of the uplink MIMO transmission at the at least one indicated uplink channel processing stage and according to the power adjustment mode.
1 more element
An apparatus for wireless communication, comprising:
