         3 . The method of  claim 1 , further comprising:
 under the condition that the PSSCH comprises the measurement information, sending, by the first terminal, the measurement information to the second terminal through a Media Access Control (MAC) Control Element (CE) in the PSSCH, the MAC CE comprising the measurement information.   
     
     
         4 . The method of  claim 1 , further comprising:
 receiving, by the first terminal, indication information carried in data sent by the second terminal, wherein the indication information is used to determine resources for transmitting the PSSCH.   
     
     
         5 . The method of  claim 4 , wherein a frequency-domain transmission resource for the PSSCH is determined based on a lowest sub-band where the data is located. 
     
     
         6 . The method of  claim 1 , wherein the measurement information comprises Reference Signal Received Power (RSRP). 
     
     
         7 . The method of  claim 1 , wherein the measurement information occupies a first resource subset of a transmission resource for the PSSCH, the first resource subset being determined according to a first criterion configured by a network or preconfigured, the first criterion including that:
 a transmission resource for the measurement information is a transmission resource on a DMRS symbol of the PSSCH and the transmission resource for the measurement information doesn't occupy a transmission resource for a DMRS of the PSSCH; or,   the transmission resource for the measurement information is a transmission resource on a time-domain symbol adjacent to the DMRS symbol of the PSSCH.

         11 . The device of  claim 8 , wherein the one or more processors are further configured to control the transceiver to:
 receive indication information carried in data sent by the second terminal, wherein the indication information is used to determine resources for transmitting the PSSCH.   
     
     
         12 . The device of  claim 11 , wherein a frequency-domain transmission resource for the PSSCH is determined based on a lowest sub-band where the data is located. 
     
     
         13 . The device of  claim 8 , wherein the measurement information comprises Reference Signal Received Power (RSRP). 
     
     
         14 . The device of  claim 8 , wherein the measurement information occupies a first resource subset of a transmission resource for the PSSCH, the first resource subset being determined according to a first criterion configured by a network or preconfigured, the first criterion including that:
 a transmission resource for the measurement information is a transmission resource on a DMRS symbol of the PSSCH and the transmission resource for the measurement information doesn't occupy a transmission resource for a DMRS of the PSSCH; or,   the transmission resource for the measurement information is a transmission resource on a time-domain symbol adjacent to the DMRS symbol of the PSSCH.   
     
     
         15 . A device for data transmission, applied to a second terminal and comprising:
 one or more processors, a memory configured to store instructions executable by the one or more processors, and a transceiver,   wherein the one or more processors are configured to control the transceiver to:   send a measurement signal to a first terminal;   receive at least one of: a Physical Sidelink Control Channel (PSCCH) or a Physical Sidelink Shared Channel (PSSCH) from the first terminal, the PSCCH or the PSSCH comprising measurement information corresponding to the measurement signal.
