Abstract
Embodiments of the present invention provide a method for transmitting Long Term Evolution in unlicensed spectrum LTE-U carrier information, a base station, and user equipment. The method includes: determining, by a base station, a physical hybrid automatic repeat request indicator channel PHICH resource; using, by the base station, the PHICH resource to indicate the LTE-U carrier information; and sending, by the base station to user equipment, the PHICH resource that indicates the LTE-U carrier information. In the embodiments of the present invention, network signaling overheads can be reduced.

A method, performed by a base station, for transmitting Long Term Evolution in unlicensed spectrum (LTE-U) carrier information simultaneously to multiple user equipment (UE) devices in a wireless communication system, the method comprising:
- determining a physical hybrid automatic repeat request indicator channel (PHICH) resource to be used by the base station to broadcast the LTE-U carrier information;
- using the PHICH resource to broadcast the LTE-U carrier information;
- and
- sending, to the multiple UE devices, an identifier of the PHICH resource that the base station uses to transmit the LTE-U carrier information.
A base station, comprising:
- a non-transitory computer readable medium having instructions stored thereon;
- and
- a computer processor coupled to the non-transitory computer readable medium and configured to execute the instructions to perform a method for transmitting Long Term Evolution in unlicensed spectrum (LTE-U) carrier information simultaneously to multiple user equipment (UE) devices in a wireless communication system, the method comprising:
- determining a physical hybrid automatic repeat request indicator channel (PHICH) resource to be used by the base station to broadcast the LTE-U carrier information;
- using the PHICH resource to broadcast the LTE-U carrier information;
- and
- sending, to the multiple UE device, an identifier of the PHICH resource that the base station uses to transmit the LTE-U carrier information.
A user equipment, comprising:
- a non-transitory computer readable medium having instructions stored thereon;
- and
- a computer processor coupled to the non-transitory computer readable medium and configured to execute the instructions to perform a method for receiving, from a base station, broadcast Long Term Evolution in unlicensed spectrum (LTE-U) carrier information simultaneously with other ones of multiple user equipment (UE) devices in a wireless communication system, the method comprising:
- determining, a physical hybrid automatic repeat request indicator channel (PHICH) resource, wherein the PHICH resource is used by the base station to broadcast the LTE-U carrier information;
- and
- obtaining, via the PHICH resource, the LTE-U carrier information broadcast by the base station via the PHICH resource.
