An information transmission method for a multi-numerology and/or multi-beam scenario, the method being performed by a terminal device and the method comprising: when the terminal device is in a power headroom report, PHR, triggering state, receiving a first indication from a network device, wherein the first indication is used to indicate a first uplink transmission resource of the terminal device, and the uplink transmission resource is used by the terminal device to perform uplink transmission with the network device, wherein the first uplink transmission resource has a first numerology and/or the first uplink transmission resource comprises at least one first uplink beam set, and wherein the first indication is an indication that is first received by the terminal device after the terminal device enters the power headroom report triggering state; and keeping the power headroom report triggering state in a first time period, and canceling the power headroom report triggering state when the first time period expires, wherein the first time period is: a second time period starting from a receiving time point of the first indication to a time domain end of the first uplink transmission resource indicated by the first indication; or a third time period starting from a receiving time point of the first indication to a time point of receiving a response signal sent by the network device to indicate that data sent on the first uplink transmission resource is successfully received; or a fourth time period starting from a receiving time point of the first indication to a time point of generating a power headroom report based on a second indication corresponding to the shortest transmission time interval of all TTIs of different numerologies used in the multi-numerology and/or multi-beam scenario after the second indication is received, wherein the second indication is used to indicate a second uplink transmission resource of the terminal device, wherein the second uplink transmission resource has a second numerology, and the second numerology is different from the first numerology and/or the second uplink transmission resource comprises a second uplink beam set different from the first uplink beam set. when the terminal device is in a power headroom report, PHR, triggering state, receiving a first indication from a network device, wherein the first indication is used to indicate a first uplink transmission resource of the terminal device, and the uplink transmission resource is used by the terminal device to perform uplink transmission with the network device, wherein the first uplink transmission resource has a first numerology and/or the first uplink transmission resource comprises at least one first uplink beam set, and wherein the first indication is an indication that is first received by the terminal device after the terminal device enters the power headroom report triggering state;

or a third time period starting from a receiving time point of the first indication to a time point of receiving a response signal sent by the network device to indicate that data sent on the first uplink transmission resource is successfully received; or a fourth time period starting from a receiving time point of the first indication to a time point of generating a power headroom report based on a second indication corresponding to the shortest transmission time interval of all TTIs of different numerologies used in the multi-numerology and/or multi-beam scenario after the second indication is received, wherein the second indication is used to indicate a second uplink transmission resource of the terminal device, wherein the second uplink transmission resource has a second numerology, and the second numerology is different from the first numerology and/or the second uplink transmission resource comprises a second uplink beam set different from the first uplink beam set. a second time period starting from a receiving time point of the first indication to a time domain end of the first uplink transmission resource indicated by the first indication; or a third time period starting from a receiving time point of the first indication to a time point of receiving a response signal sent by the network device to indicate that data sent on the first uplink transmission resource is successfully received; or a fourth time period starting from a receiving time point of the first indication to a time point of generating a power headroom report based on a second indication corresponding to the shortest transmission time interval of all TTIs of different numerologies used in the multi-numerology and/or multi-beam scenario after the second indication is received, wherein the second indication is used to indicate a second uplink transmission resource of the terminal device, wherein the second uplink transmission resource has a second numerology, and the second numerology is different from the first numerology and/or the second uplink transmission resource comprises a second uplink beam set different from the first uplink beam set.
