Using automatic gain control symbol to indicate sidelink mini-slot
Aspects of the present disclosure provide techniques for using automatic gain control symbols to indicate a sidelink mini-slot. A method performed by a transmitting user equipment includes transmitting, during a first time portion of a symbol within a slot, a first beam associated with a first receiving user equipment. The first time portion of the symbol is configured to indicate that the first receiving user equipment will receive another transmission from the transmitting user equipment during a first mini-slot within the slot associated with the first time portion. The method may further include transmitting, during a second time portion of the symbol within the slot, a second beam associated with a second receiving user equipment. The second time portion of the symbol is configured to indicate that the second receiving user equipment will receive another transmission from the transmitting user equipment during a second mini-slot within the slot.
1. A method for wireless communication by a transmitting user equipment, the method comprising:
transmitting a first automatic gain control symbol in a slot at a selected power level using one or more selected resource blocks,
wherein each selected resource block of the one or more selected resource blocks indicates a mini-slot within the slot in which the transmitting user equipment is scheduled to transmit,
and wherein the selected power level is based on a highest transmit power of any mini-slot in which the transmitting user equipment is scheduled to transmit in the slot.
2. The method of claim 1 , wherein the first automatic gain control symbol is transmitted on a first beam encompassing each beam associated with any mini-slot in which the transmitting user equipment is scheduled to transmit in the slot.
3. The method of claim 2 , wherein the selected power level is further based on a power compensation factor based on a width of the first beam.
4. The method of claim 1 , further comprising transmitting a second automatic gain control symbol to a first receiving user equipment using a second beam during a first mini-slot within the slot.
5. The method of claim 4 , further comprising transmitting a third automatic gain control symbol to a second receiving user equipment using a third beam during a second mini-slot within the slot.
6. The method of claim 5 , further comprising:
transmitting data to a first receiving user equipment using the second beam during the first mini-slot within the slot; and
transmitting data to a second receiving user equipment using the third beam during the second mini-slot within the slot.
7. The method of claim 6 , further comprising ceasing transmission for at least one symbol between transmitting during the first mini-slot and the second mini-slot.
8. A transmitting user equipment configured for wireless communication, comprising: a memory comprising computer-executable instructions; and one or more processors configured to execute the computer-executable instructions and cause the transmitting user equipment to:
transmit a first automatic gain control symbol in a slot at a selected power level using one or more selected resource blocks,
wherein each selected resource block of the one or more selected resource blocks indicates a mini-slot within the slot in which the transmitting user equipment is scheduled to transmit, and
wherein the selected power level is based on a highest transmit power of any mini-slot in which the transmitting user equipment is scheduled to transmit in the slot.
9. The transmitting user equipment of claim 8 , wherein the one or more processors are further configured to cause the transmitting user equipment to transmit the first automatic gain control symbol on a first beam encompassing each beam associated with any mini-slot in which the transmitting user equipment is scheduled to transmit in the slot.
10. The transmitting user equipment of claim 9 , wherein the selected power level is further based on a power compensation factor based on a width of the first beam.
11. The transmitting user equipment of claim 8 , wherein the one or more processors are further configured to cause the transmitting user equipment to transmit a second automatic gain control symbol to a first receiving user equipment using a second beam during a first mini-slot within the slot.
12. The transmitting user equipment of claim 11 , wherein the one or more processors are further configured to cause the transmitting user equipment to transmit a third automatic gain control symbol to a second receiving user equipment using a third beam during a second mini-slot within the slot.
13. The transmitting user equipment of claim 12 , wherein the one or more processors are further configured to cause the transmitting user equipment to:
transmit data to a first receiving user equipment using the second beam during the first mini-slot within the slot; and
transmit data to a second receiving user equipment using the third beam during the second mini-slot within the slot.
14. The transmitting user equipment of claim 13 , wherein the one or more processors are further configured to cause the transmitting user equipment to cease transmission for at least one symbol between transmitting during the first mini-slot and the second mini-slot.
15. A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by one or more processors of a transmitting user equipment, cause the transmitting user equipment to perform a method of wireless communication, comprising:
transmitting a first automatic gain control symbol in a slot at a selected power level using one or more selected resource blocks,
wherein each selected resource block of the one or more selected resource blocks indicates a mini-slot within the slot in which the transmitting user equipment is scheduled to transmit, and
wherein the selected power level is based on a highest transmit power of any mini-slot in which the transmitting user equipment is scheduled to transmit in the slot.
16. The non-transitory computer-readable medium of claim 15 , wherein the method further comprises transmitting the first automatic gain control symbol on a first beam encompassing each beam associated with any mini-slot in which the transmitting user equipment is scheduled to transmit in the slot.
17. The non-transitory computer-readable medium of claim 16 , wherein the selected power level is further based on a power compensation factor based on a width of the first beam.
18. The non-transitory computer-readable medium of claim 15 , wherein the method further comprises transmitting a second automatic gain control symbol to a first receiving user equipment using a second beam during a first mini-slot within the slot.
19. The non-transitory computer-readable medium of claim 18 , wherein the method further comprises transmitting a third automatic gain control symbol to a second receiving user equipment using a third beam during a second mini-slot within the slot.
20. The non-transitory computer-readable medium of claim 19 , wherein the method further comprises:
transmitting data to a first receiving user equipment using the second beam during the first mini-slot within the slot; and
transmitting data to a second receiving user equipment using the third beam during the second mini-slot within the slot.
