Adaptive multiple antenna transmission scheme for uplink data transmission in wireless communication systems

A radio network device, comprising:

• a processor;
• and
• a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising:
• obtaining a dataset comprising speeds of movement of a user equipment during a time period;
• modifying, based on a rate of change of a speed of movement of the user equipment as indicated by the speeds of movement of the user equipment during the time period, a threshold value associated with a transmission scheme of the user equipment to generate a modified threshold value;
• in response to determining that a current speed of movement of the user equipment is above the modified threshold value, initiating a first action to control the transmission scheme of the user equipment to be a rank-1 precoder cycling transmission scheme;
• and
• in response to determining that the current speed of movement of the user equipment is not above the modified threshold value, initiating a second action to control the transmission scheme of the user equipment to be a closed loop multiple input multiple output transmission scheme.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of a user equipment, facilitate performance of operations, the operations comprising:

• determining a dataset comprising speeds of movement the user equipment during a time period;
• modifying, based on a rate of change of a speed of movement of the user equipment as indicated by the speeds of movement of the user equipment during the time period, a first threshold value associated with a transmission protocol for the user equipment to generate a second threshold value;
• and
• in response to determining that a current speed of movement of the user equipment has transitioned to the second threshold value:
• selecting a rank-1 precoder cycling transmission protocol for use by the user equipment, and
• transmitting data from the user equipment using the rank-1 precoder cycling transmission protocol.
