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.
Claims18
A method of wireless communication performed by a user equipment (UE), the method comprising:
- generating information indicative of support for limited non-contiguous intra-band carrier aggregation, wherein the support for the limited non-contiguous intra-band carrier aggregation is support for a limited frequency range W less than a frequency range L of a particular frequency band;
- and
- communicating the information indicative of the support for limited non-contiguous intra-band carrier aggregation to one or more network entities, wherein communicating the information indicative of the support for limited non-contiguous intra-band carrier aggregation comprises transmitting the information in a control message to a first cell associated with a first base station, wherein the first base station is associated with a service provider with at least a first spectrum allotment and a second spectrum allotment separated by a frequency gap G, the frequency gap G greater than W, and wherein the method further comprises:
- receiving an indication of one or more assigned component carriers from the first cell, wherein the one or more assigned component carriers are all included in the first spectrum allotment;
- communicating with at least the first cell using the one or more assigned component carriers included in the first spectrum allotment;
- communicating with a different cell associated with a different base station after a handoff procedure;
- and
- receiving an indication of one or more assigned component carriers from the different cell, wherein the one or more assigned component carriers are all included in the second spectrum allotment.

A user equipment comprising:
- memory circuitry configured to store capability information, the capability information including capability information indicative of support for limited non-contiguous intra-band carrier aggregation, wherein the support for the limited non-contiguous intra-band carrier aggregation is support for a limited frequency range W less than a frequency range L of a particular frequency band;
- processor circuitry configured to access the memory circuitry to generate a control message including the capability information for transmission to one or more network entities;
- and
- transceiver circuitry and antenna circuitry to generate and transmit a signal to communicate the capability information in the control message to a first cell associated with a first base station, wherein the first base station is associated with a service provider with at least a first spectrum allotment and a second spectrum allotment separated by a frequency gap G, the frequency gap G greater than W, and wherein the processor circuitry, transceiver circuitry, and antenna circuitry are further configured to:
- receive an indication of one or more assigned component carriers from the first cell, wherein the one or more assigned component carriers are all included in the first spectrum allotment;
- communicate with at least the first cell using the one or more assigned component carriers included in the first spectrum allotment;
- communicate with a different cell associated with a different base station after a handoff procedure;
- and
- receive an indication of one or more assigned component carriers from the different cell, wherein the one or more assigned component carriers are all included in the second spectrum allotment.
