Techniques for declaring default operating frequencies

A method for wireless communication at a first wireless device, comprising:

• receiving, from a second wireless device, control information comprising an indication of at least one first default operating frequency of one or more default operating frequencies of the second wireless device selected based at least in part on a change in a measured interference of at least one second default operating frequency of the one or more default operating frequencies, the one or more default operating frequencies for communicating over a bandwidth based at least in part on an inter-antenna element spacing of an antenna array configuration of the second wireless device;
• transmitting, based at least in part on the indication of the one or more default operating frequencies, a first system information comprising a parameter that indicates a plurality of cells each operating using at least one antenna array configuration that is the same as the antenna array configuration of the second wireless device, wherein the parameter indicates that the first wireless device is associated with a cell of the plurality of cells and operates using at least one antenna array configuration having a corresponding inter-antenna element spacing that is within a threshold value of the inter-antenna element spacing of the antenna array configuration of the second wireless device, and wherein the parameter indicates a first default operating frequency of the first wireless device;
• configuring one or more communications parameters based at least in part on a difference between a second default operating frequency of the one or more default operating frequencies of the second wireless device and the first default operating frequency of the first wireless device satisfying a threshold difference;
• and
• communicating with the second wireless device over the bandwidth based at least in part on the difference satisfying the threshold difference and based at least in part on transmitting the first system information and in accordance with the one or more communications parameters.

An apparatus for wireless communication at a first wireless device, comprising:

• one or more processors,
• memory coupled with the one or more processors;
• and
• instructions stored in the memory and executable by the one or more processors to cause the apparatus to:
• identify, by the first wireless device, one or more default operating frequencies for communicating over a bandwidth, each default operating frequency of the one or more default operating frequencies being predetermined by an inter-antenna element spacing of an antenna array configuration of the first wireless device;
• transmit, to a second wireless device, control information comprising an indication of at least one first default operating frequency of the one or more default operating frequencies of the first wireless device selected based at least in part on a change in a measured interference of at least one second default operating frequency of the one or more default operating frequencies;
• receive, based at least in part on the indication of the one or more default operating frequencies, a first system information comprising a parameter that indicates a plurality of cells each operating using at least one antenna array configuration that is the same as the antenna array configuration of the first wireless device, wherein the parameter indicates that the second wireless device associated with a cell of the plurality of cells operates using at least one antenna array configuration having a corresponding inter-antenna element spacing that is within a threshold value of the inter-antenna element spacing of the antenna array configuration of the first wireless device, and wherein the parameter indicates a first default operating frequency of the second wireless device;
• and
• communicate with the second wireless device over the bandwidth based at least in part on receiving the first system information and in accordance with a difference between a second default operating frequency of the one or more default operating frequencies of the first wireless device and the first default operating frequency of the second wireless device satisfying a threshold difference.
