Systems, apparatus, and methods for antenna switching approach for initial acquisition procedure

摘要

This disclosure provides systems, methods, and apparatus for an initial network acquisition process via multiple antennas. In one aspect a method of establishing communications via a wireless network at a wireless communications apparatus is provided. The method includes attempting an initial acquisition process, over one or more frequencies, for establishing communications over the wireless network via a transmit circuit and a receive circuit transmitting and receiving via a first antenna. The method further includes switching the transmit circuit and the receive circuit from transmitting and receiving via the first antenna to a second antenna in response to detecting failure of the initial acquisition process. The switching is independent of a performance metric of the first or the second antenna. The method further includes re-attempting the initial acquisition process based on the switching to the second antenna over the one or more frequencies.

1. A method of establishing communications via a wireless network at a wireless communications apparatus, the method comprising:
attempting an initial acquisition process, over one or more frequencies, for establishing communications over the wireless network via a transmit circuit and a receive circuit transmitting and receiving via a first antenna; switching the transmit circuit and the receive circuit from transmitting and receiving via the first antenna to a second antenna in response to detecting failure of the initial acquisition process, the switching independent of a performance metric of the first or the second antenna; and re-attempting the initial acquisition process based on the switching to the second antenna over the one or more frequencies, wherein the first and the second antenna are selected from a plurality of antennas based on an order selected based on stored data independent of the performance metric, and the stored data corresponds to data based on previous initial acquisition process attempts for the first and second antennas; wherein the stored data indicates that the first antenna has a highest past success in the previous initial acquisition process attempts and the second antenna has a next highest past success in the previous initial acquisition process attempts.
