Abstract
Methods, systems, and devices for wireless communication are described. Techniques to use capability information for user equipment in wide band systems such as millimeter wave systems. The capability information can include information indicative of support for limited non-contiguous intra-band carrier aggregation. The capability information can include information indicative of support for sharing time and frequency tracking information between cells.
Claims20
A method of wireless communication performed by a user equipment (UE), the method comprising:
- communicating information indicating a capability of the UE to support sharing of time and frequency tracking information between at least a first component carrier for a first cell and a second component carrier for a second cell in a carrier aggregation communication process, wherein the time and frequency tracking information is information to track time, information to track frequency, or both;
- receiving a first signal from the first cell including a synchronization signal block (SS block) including first time and frequency tracking information associated with the first cell, a tracking reference signal (TRS) including the first time and frequency tracking information associated with the first cell, or both;
- and
- processing a second signal received from the second cell using second time and frequency tracking information associated with the second cell that is based at least in part on the first time and frequency tracking information associated with the first cell.
