Abstract
In some aspects, a method of wireless communication includes receiving, at a user equipment (UE) from a base station, a first message indicating a selected carrier for transmission of an uplink (UL) message. The selected carrier includes a UL carrier or a supplementary uplink (SUL) carrier. The UL carrier and the SUL carrier correspond to the same cell. The method further includes transmitting the UL message to the base station via the selected carrier. Other aspects and features are also claimed and described.
Claims30
A method of wireless communication, the method comprising:
- receiving, at a user equipment (UE) from base station, a first message indicating a selected carrier for transmission of an uplink (UL) message, the selected carrier comprising a UL carrier or a supplementary uplink (SUL) carrier, the UL carrier and the SUL carrier corresponding to the same cell;
- and
- transmitting the UL message to the base station via the selected carrier.
An apparatus configured for wireless communication, the apparatus comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor, wherein the at least one processor is configured to:
- receive, at a user equipment (UE) from base station, a first message indicating a selected carrier for transmission of an uplink (UL) message, the selected carrier comprising a UL carrier or a supplementary uplink (SUL) carrier, the UL carrier and the SUL carrier corresponding to the same cell;
- and
- initiate transmission of the UL message to the base station via the selected carrier.
A method of wireless communication, the method comprising:
- selecting, at a base station, a carrier from a group of carriers that includes an uplink (UL) carrier and a supplementary uplink (SUL) carrier, the UL carrier and the SUL carrier corresponding to the same cell;
- transmitting, to a user equipment (UE), a first message that indicates the selected carrier is for transmission of a UL message;
- and
- receiving the UL message from the UE via the selected carrier.
An apparatus configured for wireless communication, the apparatus comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor, wherein the at least one processor is configured to:
- select, at a base station, a carrier from a group of carriers that includes an uplink (UL) carrier and a supplementary uplink (SUL) carrier, the UL carrier and the SUL carrier corresponding to the same cell;
- initiate transmission, to a user equipment (UE), of a first message that indicates the selected carrier is for transmission of a UL message;
- and
- receive the UL message from the UE via the selected carrier.
