Abstract
Systems and methodologies are described that facilitate conveying information utilizing a constant phase offset on Primary Synchronization Signal (PSS). In general, the subject innovation can employ a fixed set of beams and phases in which a PSS and a Secondary Synchronization Signal (SSS) can be transmitted with the fixed set of beams and phases. Furthermore, the phase offset for PSS and SSS can be the same such that legacy user equipment is unaffected or aware of such transmissions.
Claims34
A method used in a wireless communications system, comprising:
- identifying a beam within a wireless communications environment;
- employing a fixed number of phases for the beam;
- and
- transmitting at least one of a Primary Synchronization Signal (PSS) or a Secondary Synchronization Signal (SSS) with the fixed number of phases for the beam;
- and
- utilizing the fixed number of phases for the beam to convey information to a User Equipment (UE),
- wherein the conveyed information is related to a number of antennas deployed in the wireless communication system.
A wireless communications apparatus, comprising:
- at least one processor configured to:
- identify a beam within a wireless communications environment;
- employ a fixed number of phases for the beam;
- transmit at least one of a Primary Synchronization Signal (PSS) or a Secondary Synchronization Signal (SSS) with the fixed number of phases for the beam;
- utilize the fixed number of phases for the beam to convey information to a User Equipment (UE), wherein the conveyed information is related to a number of antennas deployed in the wireless communications environment;
- and
- a memory coupled to the at least one processor.
A computer program product, comprising:
- a non-transitory computer-readable medium comprising:
- code for causing the at least one computer to identify a beam within a wireless communications environment;
- code for causing the at least one computer to employ a fixed number of phases for the beam;
- code for causing the at least one computer to utilizing the fixed number of phases for the beam to convey information to a User Equipment (UE), wherein the conveyed information is related to a number of antennas deployed in the wireless communications environment;
