The method for transmitting a PSBCH of a first user equipment includes transmitting, to one or more second user equipments, a PSBCH carrying information, and the information carried in the PSBCH is used to determine a periodicity and a number of slots. This can reduce a payload size of the information carried in the PSBCH. ## Claims ### Claim 1 A method for transmitting a physical sidelink broadcast channel (PSBCH) of a first user equipment, comprising: transmitting, to one or more second user equipments, a PSBCH carrying information, wherein the information carried in the PSBCH is used to determine a periodicity and a number of slots wherein the slots comprise sidelink (SL) slots; and obtaining a first reference subcarrier spacing (SCS), wherein the first reference SCS is configured by the network; wherein the number of slots which is determined by the information carried in the PSBCH is further determined by the first reference SCS and a second reference SCS, wherein the second reference SCS is pre-configured, or determined by the information carried in the PSBCH. ### Claim 2 (depends on 1) The method of claim 1, wherein only a pattern 1 is configured by a network, the information carried in PSBCH is determined by parameters configured in pattern 1. ### Claim 3 (depends on 2) The method of claim 2, wherein the periodicity which is determined by the information carried in the PSBCH is determined by a periodicity configured in the pattern 1. ### Claim 4 (depends on 2) The method of claim 2, wherein the number of slots which is determined by the information carried in the PSBCH is determined by a number of slots configured in the pattern 1. ### Claim 5 (depends on 4) The method of claim 4, wherein the slots configured in the pattern 1 comprise UL slots. ### Claim 6 (depends on 1) The method of claim 1, wherein both a pattern 1 and a pattern 2 are configured by the network, the information carried in PSBCH is determined by parameters configured in pattern 1 and/or pattern 2. ### Claim 7 (depends on 6) The method of claim 6, wherein the periodicity which is determined by the information carried in the PSBCH is determined by a first periodicity configured in the pattern 1 and a second periodicity configured in the pattern 2. ### Claim 8 (depends on 6) The method of claim 6, wherein the number of slots which is determined by the information carried in the PSBCH is determined by a number of slots configured in at least one of the pattern 1 and the pattern 2. ### Claim 9 (depends on 8) The method of claim 8, wherein the slots configured in at least one of the pattern 1 and the pattern 2 comprise UL slots. ### Claim 10 (depends on 1) The method of claim 1, wherein the information carried in the PSBCH further determines a number of symbols wherein the symbols comprise SL symbols. ### Claim 11 (depends on 1) The method of claim 1, wherein the first user equipment is in coverage of a cell. ### Claim 12 A first user equipment for transmitting a physical sidelink broadcast channel (PSBCH), comprising: a memory; a transceiver; and a processor coupled to the memory and the transceiver, wherein the processor is configured to control the transceiver to transmit, to one or more second user equipments, a PSBCH carrying information, wherein the information carried in the PSBCH is used to determine a periodicity and a number of slots wherein the slots comprise sidelink (SL) slots; and obtain a first reference subcarrier spacing (SCS), wherein the first reference SCS is configured by a network; wherein the number of slots which is determined by the information carried in the PSBCH is further determined by the first reference SCS and a second reference SCS, wherein the second reference SCS is pre-configured, or determined by the information carried in the PSBCH. ### Claim 13 (depends on 12) The first user equipment of claim 12, wherein only a pattern 1 is configured by a network, the information carried in PSBCH is determined by parameters configured in pattern 1, the periodicity which is determined by the information carried in the PSBCH is determined by a periodicity configured in the pattern 1, the number of slots which is determined by the information carried in the PSBCH is determined by a number of slots configured in the pattern 1, the slots configured in the pattern 1 comprise UL slots. ### Claim 14 (depends on 12) The first user equipment of claim 12, wherein both a pattern 1 and a pattern 2 are configured by the network, the information carried in PSBCH is determined by parameters configured in pattern 1 and/or pattern 2, the periodicity which is determined by the information carried in the PSBCH is determined by a first periodicity configured in the pattern 1 and a second periodicity configured in the pattern 2, the number of slots which is determined by the information carried in the PSBCH is determined by a number of slots configured in at least one of the pattern 1 and the pattern 2, the slots configured in at least one of the pattern 1 and the pattern 2 comprise UL slots. ### Claim 15 (depends on 12) The first user equipment of claim 12, wherein the information carried in the PSBCH further determines a number of symbols wherein the symbols comprise SL symbols. ### Claim 16 (depends on 12) The first user equipment of claim 12, wherein the first user equipment is in coverage of a cell.
