UE INITIATED SCELL CONNECTION ESTABLISHMENT

摘要

Methods, systems, devices, and apparatuses are described for wireless communications in which a wireless device may identify a small cell (e.g., SCell) and establish an independent connection with the small cell based at least in part on selection parameters received from a macro cell (e.g., PCell). The selection parameters may include power and/or quality parameters, as wells as a set of candidate cells from which to make the selection. The macro and small cells may be in communication with each other but need not be associated with the same base station (i.e., are not collocated). Once the small cell connection is established, the device may communicate with both cells concurrently. Available uplink data and/or downlink data may trigger the need for the device to connect with the small cell. For example, the small cell connection may be used to communicate uplink/downlink data associated with certain quality-of-service (QoS) and/or bearer identifier.

主权项

1. A method for wireless communications by a wireless device, comprising:
receiving selection parameters from a first cell; identifying and selecting a second cell based at least in part on the selection parameters received from the first cell, the first cell being associated with a first base station and the second cell being associated with a second base station, and the first and second cells being in communication with each other; establishing an independent connection with the second cell; and communicating with the first and second cells concurrently.
