Receiver-based resource reservation

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmitting UE, a first transmission on a first resource, wherein the first transmission includes information associated with reserving a second resource for a second transmission by the first transmitting UE. The UE may transmit, for reception by one or more second transmitting UEs and before an occurrence of the second resource, a message associated with indicating that the second resource is reserved for the second transmission by the first transmitting UE. Numerous other aspects are provided.

What is claimed is: 
     
         1 . A method of wireless communication performed by a user equipment (UE), comprising:
 receiving, from a first UE, a message associated with indicating that a particular resource is reserved for a particular transmission by a second UE; and   selectively forgoing, based at least in part on a priority of the particular transmission, use of the particular resource that is reserved for the particular transmission by the second UE and to the first UE.   
     
     
         2 . The method of  claim 1 , wherein selectively forgoing use of the particular resource comprises:
 yielding a transmission using the particular resource based at least in part on the priority of the particular transmission.   
     
     
         3 . The method of  claim 2 , wherein yielding transmission comprises:
 dropping a transmission on the particular resource.   
     
     
         4 . The method of  claim 2 , wherein yielding transmission comprises:
 altering a transmit power for a transmission on the particular resource.   
     
     
         5 . The method of  claim 4 , wherein the transmit power is selected based at least in part on a reference signal received power (RSRP) indication or a transmit power indication from the first UE. 
     
     
         6 . The method of  claim 1 , wherein selectively forgoing use of the particular resource comprises:
 transmitting a higher priority transmission than the particular transmission using the particular resource.   
     
     
         7 . The method of  claim 1 , further comprising:
 selecting a first resource for a first control transmission and data transmission based at least in part on the particular resource and a second resource for a second control transmission and data transmission based at least in part on the particular resource;   transmitting, using the first resource, the first control transmission and data transmission with information to indicate the second resource and to reserve the second resource; and   selectively transmitting, using the second resource, the second control transmission and data transmission.   
     
     
         8 . The method of  claim 7 , wherein selecting the first resource and the second resource comprises:
 excluding resource reservations by one or more transmitting UEs and one or more receiving UEs from available resources for selection; and   selecting the first resource and the second resource based at least in part on excluding the resource reservations.

         11 . The UE of  claim 10 , wherein, to selectively forgo use of the particular resource, the one or more processors are configured to:
 yield a transmission using the particular resource based at least in part on the priority of the particular transmission.   
     
     
         12 . The UE of  claim 11 , wherein, to yield the transmission, the one or more processors are configured to:
 drop a transmission on the particular resource.   
     
     
         13 . The UE of  claim 11 , wherein, to yield the transmission, the one or more processors are configured to:
 alter a transmit power for a transmission on the particular resource.   
     
     
         14 . The UE of  claim 13 , wherein the transmit power is selected based at least in part on a reference signal received power (RSRP) indication or a transmit power indication from the first UE. 
     
     
         15 . The UE of  claim 11 , wherein, to selectively forgo use of the particular resource, the one or more processors are configured to:
 transmit a higher priority transmission than the particular transmission using the particular resource.   
     
     
         16 . The UE of  claim 11 , wherein the one or more processors are configured to:
 select a first resource for a first control transmission and data transmission based at least in part on the particular resource and a second resource for a second control transmission and data transmission based at least in part on the particular resource;   transmit, using the first resource, the first control transmission and data transmission with information to indicate the second resource and to reserve the second resource; and   selectively transmit, using the second resource, the second control transmission and data transmission.
