Abstract
Aspects of the present disclosure relate to techniques that may be utilized in networks with relatively dense deployments of small cells and/or various other types of cells, each of which may or may not support a dormancy cell operation.
Claims25
A method for wireless communications by a user equipment (UE) within a plurality of cells, comprising:
- determining that at least one cell in the plurality of cells supports a dormancy state;
- monitoring for a reference signal in a subframe for the at least one cell, wherein the reference signal is associated with the dormancy state;
- determining a cell identity (ID) based at least in part on the reference signal;
- and
- reporting a measurement, along with the determined cell ID, based at least in part on the reference signal.
An apparatus for wireless communications by a user equipment (UE) within a plurality of cells, comprising:
- means for determining that at least one cell in the plurality of cells supports a dormancy state;
- means for monitoring for a reference signal in a subframe for the at least one cell, wherein the reference signal is associated with the dormancy state;
- means for determining a cell identity (ID) based at least in part on the reference signal;
- and
- means for reporting a measurement, along with the determined cell ID, based at least in part on the reference signal.
A method for wireless communications by a base station (BS) within a plurality of cells, comprising:
- entering a dormancy state;
- and
- transmitting a reference signal in a subframe, wherein the reference signal is associated with the dormancy state and conveys at least partial information regarding a cell identity (ID).
