A method of a first device for performing sidelink transmission to a second device, comprising: the first device is configured with a first resource pool for sidelink transmission ; the first device is configured with only a first number of consecutive symbols in each slot for sidelink such that each slot in the first resource pool comprises only one subset of consecutive symbols for sidelink, wherein the first number of consecutive symbols in each slot for sidelink is less than all Orthogonal Frequency Division Multiplexing, in the following also referred to as OFDM, symbols in each slot ; the first device performs a resource selection, for sidelink transmission, among a plurality of slots in the first resource pool , wherein said resource selection comprises that the first device selects a first sidelink transmission resource in a first slot of the first resource pool and a second sidelink transmission resource in a third slot of the first resource pool , wherein the first sidelink transmission resource contains symbols among the first number of consecutive symbols in the first slot and/or the second sidelink transmission resource contains symbols among the first number of consecutive symbols in the third slot; and the first device performs sidelink transmission of a Transport Block, in the following also referred to as TB, on the first sidelink transmission resource and performs sidelink transmission of the TB on the second sidelink transmission resource , characterized in that the subset of consecutive symbols for sidelink of each slot in the first resource pool comprises the same first number of consecutive symbols. the first device is configured with a first resource pool for sidelink transmission ; the first device is configured with only a first number of consecutive symbols in each slot for sidelink such that each slot in the first resource pool comprises only one subset of consecutive symbols for sidelink, wherein the first number of consecutive symbols in each slot for sidelink is less than all Orthogonal Frequency Division Multiplexing, in the following also referred to as OFDM, symbols in each slot ; the first device performs a resource selection, for sidelink transmission, among a plurality of slots in the first resource pool , wherein said resource selection comprises that the first device selects a first sidelink transmission resource in a first slot of the first resource pool and a second sidelink transmission resource in a third slot of the first resource pool , wherein the first sidelink transmission resource contains symbols among the first number of consecutive symbols in the first slot and/or the second sidelink transmission resource contains symbols among the first number of consecutive symbols in the third slot; and the first device performs sidelink transmission of a Transport Block, in the following also referred to as TB, on the first sidelink transmission resource and performs sidelink transmission of the TB on the second sidelink transmission resource , characterized in that the subset of consecutive symbols for sidelink of each slot in the first resource pool comprises the same first number of consecutive symbols. <EOS>
