Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a resource for a joint uplink transmission comprising a sounding reference signal and a scheduling request. The UE may receive a grant of a set of resources for an uplink data transmission to a base station. The UE may perform the joint uplink transmission comprising the sounding reference signal and the scheduling request using the resource for the joint uplink transmission in connection with performing the uplink data transmission using the set of resources for the uplink.

Claims (54)

1. A method for wireless communications at a user equipment (UE), comprising:

performing a first uplink data transmission using a single transport block and a first modulation coding scheme;

transmitting an indication that uplink data is to be transmitted in a second uplink data transmission;

receiving, based at least in part on the indication, a grant triggering the second uplink data transmission, wherein the grant triggers the second uplink data transmission using a plurality of transport blocks;

identifying, based at least in part on the grant, at least one of a repetition pattern, a frequency hopping pattern, a demodulation reference signal bundling, or any combination thereof; and

performing the second uplink data transmission using a set of resources and a second modulation coding scheme different than the first modulation coding scheme based at least in part on the grant and according to the repetition pattern, the frequency hopping pattern, the demodulation reference signal bundling, or a combination thereof, the set of resources spanning the plurality of transport blocks.

2. The method of claim 1 , further comprising:

receiving a signal indicating the set of resources spanning the plurality of transport blocks and the second modulation coding scheme.

3. The method of claim 1 , further comprising:

identifying the set of resources spanning the plurality of transport blocks based at least in part on the grant.

4. A method for wireless communications at a base station, comprising:

receiving, from a user equipment (UE), a first uplink data transmission using a single transport block and a first modulation coding scheme;

receiving, from the UE, an indication that uplink data is to be transmitted in a second uplink data transmission;

transmitting, based at least in part on the indication, a grant triggering the second uplink data transmission, wherein the grant triggers the second uplink data transmission using a plurality of transport blocks;

identifying, based at least in part on the grant, at least one of a repetition pattern, a frequency hopping pattern, a demodulation reference signal bundling, or any combination thereof, wherein the second uplink data transmission is performed according to the repetition pattern, the frequency hopping pattern, the demodulation reference signal bundling, or a combination thereof; and

receiving the second uplink data transmission using a set of resources and a second modulation coding scheme different than the first modulation coding scheme based at least in part on the grant, the set of resources spanning the plurality of transport blocks.

5. The method of claim 4 , further comprising:

transmitting a signal indicating the set of resources spanning the plurality of transport blocks and the second modulation coding scheme.

6. The method of claim 4 , further comprising:

identifying the set of resources spanning the plurality of transport blocks based at least in part on the grant.

7. An apparatus for wireless communications at a user equipment (UE), comprising:

one or more processors; and

one or more memories coupled with the one or more processors and that store executable code that, when executed by the one or more processors, is configured to cause the UE to:

perform a first uplink data transmission using a single transport block and a first modulation coding scheme;

transmit an indication that uplink data is to be transmitted in a second uplink data transmission;

receive, based at least in part on the indication, a grant triggering the second uplink data transmission, wherein the grant triggers the second uplink data transmission using a plurality of transport blocks;

identify, based at least in part on the grant, at least one of a repetition pattern, a frequency hopping pattern, a demodulation reference signal bundling, or any combination thereof; and

receive a signal indicating the set of resources spanning the plurality of transport blocks and the second modulation coding scheme.

9. The apparatus of claim 7 , wherein the executable code is further configured to cause the UE to:

identify the set of resources spanning the plurality of transport blocks based at least in part on the grant.

10. An apparatus for wireless communications at a network entity, comprising:

transmit a signal indicating the set of resources spanning the plurality of transport blocks and the second modulation coding scheme.

12. The apparatus of claim 10 , wherein the executable code is further configured to cause the network entity to:

identify the set of resources spanning the plurality of transport blocks based at least in part on the grant.

13. An apparatus for wireless communications at a user equipment (UE), comprising:

means for performing a first uplink data transmission using a single transport block and a first modulation coding scheme;

means for transmitting an indication that uplink data is to be transmitted in a second uplink data transmission;

means for receiving, based at least in part on the indication, a grant triggering the second uplink data transmission, wherein the grant triggers the second uplink data transmission using a plurality of transport blocks;

means for identifying, based at least in part on the grant, at least one of a repetition pattern, a frequency hopping pattern, a demodulation reference signal bundling, or any combination thereof; and

means for performing the second uplink data transmission using a set of resources and a second modulation coding scheme different than the first modulation coding scheme based at least in part on the grant and according to the repetition pattern, the frequency hopping pattern, the demodulation reference signal bundling, or a combination thereof, the set of resources spanning the plurality of transport blocks.
