Aspects relate to mechanisms for a wireless communication device to select between a cyclic delay diversity mode and an antenna switch diversity mode for transmission of a signal based on at least one parameter associated with communication over a wireless channel. The parameter(s) may include a channel estimation parameter associated with the wireless channel, a communication parameter associated with at least one communication on the wireless channel, or a combination thereof.

Antenna switch diversity or cyclic delay diversity selection

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to operate in an antenna switch diversity mode to transmit an uplink signal according to an antenna switching pattern, the antenna switching pattern comprising switching between a first transmit chain coupled to a first antenna and a second transmit chain coupled to a second antenna. The UE may transmit at least a first portion of the uplink signal using the first transmit chain coupled to the first antenna, the first transmit chain coupled to the first antenna. The UE may transmit at least a second portion of the uplink signal using the second transmit chain coupled to the second antenna, the second transmit chain coupled to the second antenna.
