Method and apparatus for connection point discovery and association in a directional wireless network

摘要

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus listens for directional signal beams according to a first pattern, detects a plurality of discovery signals respectively from a plurality of connection points (CPs), wherein each CP transmits a discovery signal by transmitting a directional beam according to a respective pattern, determines information related to each CP based on the discovery signal detected from a respective CP, determines a timeslot for transmitting an association signal to each CP, wherein a respective timeslot is determined based on the information determined for the respective CP or a timeslot in which the respective discovery signal is transmitted by the respective CP according to the respective pattern, and transmits an association signal to each CP in the respective timeslot according to a determined beamforming direction of the UE and a determined beamforming direction of the respective CP.

主权项

1. A method of wireless communication at a user equipment (UE), comprising:
performing discovery signal detection by listening for at least one directional beam according to a first pattern; detecting a plurality of discovery signals respectively from a plurality of connection points (CPs), wherein each CP transmits a discovery signal by transmitting a directional beam according to a respective pattern; determining information related to each CP based on the discovery signal detected from a respective CP; determining a beamforming direction of the UE based on a direction of the first pattern at which a discovery signal having a high signal quality is received; determining a beamforming direction of each CP based on a direction of the respective pattern at which a respective discovery signal is transmitted; determining a timeslot for transmitting an association signal to each CP, wherein a respective timeslot is determined based on the information determined for the respective CP or based on a timeslot in which the respective discovery signal is transmitted by the respective CP according to the respective pattern, wherein the information comprises at least one of:
a cell identifier (ID) of the respective CP; ora mapping between the timeslot for transmitting the association signal to the respective CP and the timeslot in which the respective discovery signal is transmitted by the respective CP according to the respective pattern, and wherein the mapping is a function of the cell ID; and transmitting the association signal to each CP in the respective timeslot according to the beamforming direction of the UE and the beamforming direction of the respective CP.
