Abstract
Wireless communications systems and methods related to communicating in a communication medium are provided. A first wireless communication device communicates with a second wireless communication device, a first scheduling grant. The first wireless communication device communicates, with the second wireless communication device, a second scheduling grant including at least one of a start slot index (SSI) or a slot format indicator (SFI). The first wireless communication device communicates, with the second wireless communication device, an uplink communication signal based on the first scheduling grant and the second scheduling grant.
Claims28
A method of wireless communication by a user equipment (UE), comprising:
- receiving, from a base station (BS), a first-stage scheduling grant;
- receiving, from the BS, an additional first-stage scheduling grant, wherein the additional first-stage scheduling grant is associated with the first-stage scheduling grant;
- receiving, from the BS, a second-stage scheduling grant including at least one of a start slot index (SSI) or a slot format indicator (SFI), wherein the second-stage scheduling grant corresponds to one of the first-stage scheduling grant or the additional first-stage scheduling grant;
- and
- transmitting, to the BS, an uplink communication signal based on the second-stage scheduling grant and the one of the first-stage scheduling grant or the additional first-stage scheduling grant.
An apparatus comprising:
- a processor;
- and
- a transceiver in communication with the processor configured to:
- receive, from a base station (BS), a first-stage scheduling grant;
- receive, from the BS, an additional first-stage scheduling grant, wherein the additional first-stage scheduling grant is associated with the first-stage scheduling grant;
- receive, from the BS, a second-stage scheduling grant including at least one of a start slot index (SSI) or a slot format indicator (SFI), wherein the second-stage scheduling grant corresponds to one of the first-stage scheduling grant or the additional first-stage scheduling grant;
- and
- transmit, to the BS, an uplink communication signal based on the second-stage scheduling grant and the one of the first-stage scheduling grant or the additional first-stage scheduling grant.
A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:
- code for causing a user equipment (UE) to receive, from a base station (BS), a first-stage scheduling grant;
- code for causing the UE to receive, from the BS, an additional first-stage scheduling grant, wherein the additional first-stage scheduling grant is associated with the first-stage scheduling grant;
- code for causing the UE to receive, from the BS, a second-stage scheduling grant including at least one of a start slot index (SSI) or a slot format indicator (SFI), wherein the second-stage scheduling grant corresponds to one of the first-stage scheduling grant or the additional first-stage scheduling grant;
- and
- code for causing the UE to transmit, to the BS, an uplink communication signal based on the second-stage scheduling grant and the one of the first-stage scheduling grant or the additional first-stage scheduling grant.
