Abstract
This disclosure provides systems, methods, and devices for wireless communication that support use of a supplemental uplink (SUL) carrier. In a first aspect, a user equipment (UE) is configured to receive, from a base station, a carrier set configuration indicating multiple uplink (UL) carriers. The multiple UL carriers include multiple SUL carriers and a non-SUL carrier. The UE is further configured to select one or more carriers of the multiple UL carriers, and transmit a channel on each carrier of the one or more carriers. Other aspects and features are also claimed and described.
Claims25
A method of wireless communication performed by a user equipment (UE), the method comprising:
- receiving, from a base station, a carrier set configuration indicating multiple uplink (UL) carriers, the multiple UL carriers including multiple supplemental uplink (SUL) carriers and a non-SUL carrier, wherein the multiple SUL carriers include a primary SUL carrier and one or more secondary SUL carriers;
- receiving, from the base station, a carrier selection indicator included in downlink control information (DCI), wherein the carrier selection indicator includes a first DCI associated with a first carrier of the multiple UL carriers and a second DCI associated with a second carrier of the multiple UL carriers;
- selecting one or more carriers of the multiple UL carriers, wherein the one or more carriers are selected based on the carrier selection indicator;
- and
- transmitting a channel on each carrier of the one or more carriers.
A method of wireless communication performed by a base station, the method comprising:
- transmitting, to a user equipment (UE), a carrier set configuration indicating multiple uplink (UL) carriers, the multiple UL carriers including multiple supplemental uplink (SUL) carriers and a non-SUL carrier, wherein the multiple SUL carriers include a primary SUL carrier and one or more secondary SUL carriers;
- selecting one or more carriers of the multiple UL carriers;
- transmitting a carrier selection indicator indicating one or more carriers of the multiple UL carriers, wherein the carrier selection indicator includes a first DCI associated with a first carrier of the multiple UL carriers and a second DCI associated with a second carrier of the multiple UL carriers;
- and
- receiving, from the UE, a channel on each carrier of the one or more carriers.
A user equipment (UE) comprising:
- at least one processor;
- and
- a memory coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor, is configured to:
- receive, from a base station, a carrier set configuration indicating multiple uplink (UL) carriers, the multiple UL carriers including multiple supplemental uplink (SUL) carriers and a non-SUL carrier, wherein the multiple SUL carriers include a primary SUL carrier and one or more secondary SUL carriers;
- receive, from the base station, a carrier selection indicator included in downlink control information (DCI), wherein the carrier selection indicator includes a first DCI associated with a first carrier of the multiple UL carriers and a second DCI associated with a second carrier of the multiple UL carriers
- select one or more carriers of the multiple UL carriers, wherein the one or more carriers are selected based on the carrier selection indicator;
- and
- initiate transmission of a channel on each carrier of the one or more carriers.
A base station comprising:
- at least one processor;
- and
- a memory coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor, is configured to:
- initiate transmission, to a user equipment (UE), of a carrier set configuration indicating multiple uplink (UL) carriers, the multiple UL carriers including multiple supplemental uplink (SUL) carriers and a non-SUL carrier, wherein the multiple SUL carriers include a primary SUL carrier and one or more secondary SUL carriers;
- select one or more carriers of the multiple UL carriers;
- transmit a carrier selection indicator indicating one or more carriers of the multiple UL carriers, wherein the carrier selection indicator includes a first DCI associated with a first carrier of the multiple UL carriers and a second DCI associated with a second carrier of the multiple UL carriers;
- and
- receive, from the UE, a channel on each carrier of the one or more carriers.
