Information sending and information determining method and apparatus

A terminal device, comprising:

• a transmitter;
• a processor;
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
• determining a first time length corresponding to first information, wherein the first information comprises information about a data transmission resource;
• and
• sending, using the transmitter, a scheduling request on a first resource, wherein a time length of the first resource is equal to the first time length, wherein the scheduling request requests the data transmission resource, wherein the scheduling request is sent independent of a periodic uplink control channel resource related to the terminal device, wherein the periodic uplink control channel resource is set by a network device, and wherein the sending, by the terminal device, the scheduling request on the first resource comprises sending, by the terminal device based on second information, the scheduling request on the first resource;
• wherein:
• time domain resources occupied by the second information comprise first M symbols in time domain resources of the first resource and last N symbols in the time domain resources of the first resource, and the first time length is a quantity of symbols from a first symbol of the M symbols to a last symbol of the N symbols;
• or
• the time domain resources occupied by the second information comprise first M symbols in time domain resources of the first resource and N symbols after the time domain resources of the first resource, the first time length is a sum of a quantity of symbols between a first symbol of the M symbols and a last symbol of the N symbols and a quantity of the M symbols, and the terminal device further sends the second information on the N symbols;
• or
• the time domain resources occupied by the second information comprise M symbols before time domain resources of the first resource and last N symbols in the time domain resources of the first resource, the first time length is a sum of a quantity of symbols between a first symbol of the M symbols and a last symbol of the N symbols and a quantity of the N symbols, and the terminal device further sends the second information on the M symbols;
• or
• the time domain resources occupied by the second information comprise M symbols before time domain resources of the first resource and N symbols after the time domain resources of the first resource, the first time length is a quantity of symbols between a first symbol of the M symbols and a last symbol of the N symbols, and the terminal device further sends the second information on the M symbols and the N symbols;
• and
• wherein M and N are both positive integers.

A network device, comprising:

• a processor;
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
• determining a first time length of a first resource, wherein the first resource is used to carry a scheduling request that is received by the network device from a terminal device, wherein the scheduling request requests a data transmission resource, and wherein the scheduling request is received independent of a periodic uplink control channel resource related to the terminal device that is set by the network device;
• and
• determining first information corresponding to the first time length, wherein the first information comprises information about the data transmission resource, and wherein the instructions for determining the first information corresponding to the first time length further comprise instructions for:
• determining, based on a first correspondence, the first information corresponding to the first time length, wherein the first correspondence is between P time lengths and the first information, the P time lengths comprise the first time length, and P is an integer greater than or equal to 2;
• or
• determining, based on a second correspondence, the first information corresponding to the first time length, wherein the second correspondence is between a first time length range and the first information, and the first time length range comprises the first time length;
• or
• determining, based on a third correspondence, the first information corresponding to the first time length, wherein the third correspondence is between the first time length and Q pieces of information, the Q pieces of information comprise the first information, and Q is a positive integer.
