Abstract

The present disclosure provides a method for a base station informing a user equipment (UE) of a resource configuration for D2D PSCCH, and corresponding base station and user equipment. The method comprising: generating D2D grant information, the D2D grant information including D2D PSCCH resource configuration instruction information which is used to indicate the time-frequency position of a first physical resource block pair for transmitting PSCCH; and transmitting the D2D grant information to the UE, wherein the time-frequency position of a second physical resource block pair for transmitting PSCCH can be derived from the time-frequency position of the first physical resource block pair.

We claim: 
     
         1 . A method performed by an eNodeB, comprising:
 generating 1st indicate information which indicates time-frequency positions of a resource block pair used for second transmission of Physical Sidelink Control Channel (PSCCH); and   sending the 1st indicate information to a User Equipment,   wherein a frequency position of the resource block pair for second transmission of PSCCH is determined by an offset to the resource block pair for transmitting first PSCCH, wherein the offset is related to a half of a frequency domain resource pool size configured by RRC.   
     
     
         2 . A method performed by a User Equipment (UE), comprising:
 receiving 1st indicate information from an eNodeB; and   determining time-frequency positions of a resource block pair used for second transmission of Physical Sidelink Control Channel (PSCCH) based on the 1st indicate information,   wherein a frequency position of the resource block pair for second transmission of PSCCH is determined by an offset to the resource block pair for transmitting first PSCCH, wherein the offset is related to a half of a frequency domain resource pool size configured by RRC.   
     
     
         3 . An eNodeB, comprising:
 generating circuitry configured to generate 1st indicate information which indicates time-frequency positions of a resource block pair used for second transmission of Physical Sidelink Control Channel (PSCCH); and   sending circuitry configured to send the 1st indicate information to User Equipment,   wherein a frequency position of the resource block pair for second transmission of PSCCH is determined by an offset to the resource block pair for transmitting first PSCCH, wherein the offset is related to a half of a frequency domain resource pool size configured by RRC.   
     
     
         4 . A User Equipment (UE), comprising:
 receiving circuitry configured to receive 1st indicate information from an eNodeB; and   determining circuitry configured to determine time-frequency positions of a resource block pair used for second transmission of Physical Sidelink Control Channel (PSCCH) based on the 1st indicate information,   wherein a frequency position of the resource block pair for second transmission of PSCCH is determined by an offset to the resource block pair for transmitting first PSCCH, wherein the offset is related to a half of a frequency domain resource pool size configured by RRC.
