The method includes: sending, by a terminal, an uplink resource request by using a power of a; if the terminal receives no resource allocation signaling within a predetermined time after the uplink resource request is sent, sending, by the terminal, the uplink resource request again by using a power of b1, wherein b1 is greater than a. Embodiments of the present invention may improve communication efficiency. ## Claims ### Claim 1 A power adjustment method, comprising: sending, by a terminal, an uplink resource request by using a power of a; and if no resource allocation signaling is received by the terminal within a predetermined time after the uplink resource request is sent, sending, by the terminal, the uplink resource request again by using a power of b1, wherein b1 is greater than a. ### Claim 2 (depends on 1) The method according to claim 1, wherein the method further comprises: if no resource allocation signaling is received by the terminal within the predetermined time after the terminal sends the uplink resource request by using the power of b1, sending, by the terminal, the uplink resource request again by using a power of b2, wherein b2 is greater than b1. ### Claim at position 3 3-6. (canceled) ### Claim 7 (depends on 1) The method according to claim 1, further comprising: when there is a to-be-sent uplink resource request, and a time difference between a current time and a sending time of a previous uplink resource request is greater than or equal to two periods, sending, by the terminal, the to-be-sent uplink resource request by using the power of a. ### Claim 8 A power adjustment method, comprising: sending, by a terminal, an uplink resource request by using a power of a; if no resource allocation signaling is received by the terminal within a predetermined time after the uplink resource request is sent, sending, by the terminal, the uplink resource request again by using the power of a; and if the terminal sends the uplink resource request n times by using the power of a, and no resource allocation signaling is received by the terminal within the predetermined time after the uplink resource request is sent each of the n times, sending, by the terminal, the uplink resource request again by using a power of b1, wherein b1 is greater than a, and n is greater than or equal to 2. ### Claim 9 (depends on 8) The method according to claim 8, further comprising: if the terminal sends the uplink resource request n times by using the power of b1, and no resource allocation signaling is received by the terminal within the predetermined time after the uplink resource request is sent each of the n times, sending, by the terminal, the uplink resource request again by using a power of b2, wherein b2 is greater than b1. ### Claim 10 (depends on 9) The method according to claim 9, wherein b2−b1=b1−a=δ. ### Claim 11 (depends on 8) The method according to claim 8, wherein a difference between b1 and a does not exceed a threshold, and/or a difference between b2 and a does not exceed the threshold. ### Claim 12 (depends on 11) The method according to claim 11, wherein the threshold is determined in one or more of the following manners: the threshold is a fixed value; and/or the threshold is a value obtained through calculation based on the power of a. ### Claim 13 (depends on 8) The method according to claim 8, further comprising: if the terminal receives resource allocation signaling within the predetermined time after the terminal sends the uplink resource request by using the power of b1 or b2, adjusting, by the terminal, a power for the uplink resource request to a. ### Claim 14 (depends on 8) The method according to claim 8, further comprising: when there is a to-be-sent uplink resource request, and a time difference between a current time and a sending time of a previous uplink resource request is greater than or equal to two periods, sending, by the terminal, the to-be-sent uplink resource request by using the power of a. ### Claim 15 A power adjustment method, comprising: sending, by a terminal, uplink data to a base station by using a power of a; receiving, by the terminal, response information from the base station; and when the response information is information used to indicate that the uplink data is not successfully decoded, sending, by the terminal, the uplink data to the base station again by using a power of b1, wherein b1 is greater than a. ### Claim 16 (depends on 15) The method according to claim 15, wherein when the response information is the information used to indicate that the uplink data is not successfully decoded, the method further comprises: determining, by the terminal, a to-be-adjusted value; and, wherein sending, by the terminal, the uplink data to the base station again by using the power of b1 comprises: when the to-be-adjusted value is less than or equal to a first threshold, sending, by the terminal, the uplink data to the base station again by using the power of b1. ### Claim 17 (depends on 16) The method according to claim 16, wherein the method further comprises: when the to-be-adjusted value is greater than the first threshold, sending, by the terminal, the uplink data to the base station again by using the power of a. ### Claim 18 (depends on 15) The method according to claim 15, wherein the method further comprises: when the response information indicates that the uplink data is successfully decoded, adjusting, by the terminal, a power for sending the uplink data to the base station to c, wherein c is less than a. ### Claim 19 (depends on 18) The method according to claim 18, wherein when the response information is the information indicating that the uplink data is successfully decoded, the method further comprises: counting, by the terminal, a quantity of times the response information is the information used to indicate the uplink data is successfully decoded; when the quantity of times is equal to a preset quantity of times, resetting, by the terminal, the counted quantity of times to zero, and adjusting the power for sending the uplink data to the base station to c. ### Claim 20 (depends on 19) The method according to claim 19, wherein the method further comprises: when a sum of a previous adjustment value and a power increment is less than or equal to a first threshold, counting, by the terminal, a quantity of times the response information is the information indicating that the uplink data is successfully decoded, or adjusting the power for sending the uplink data to the base station to c. ### Claim at position 18 21-32. (canceled) ### Claim 33 (depends on 8) A terminal, comprising a processor, a memory, and a transceiver, wherein the transceiver is configured to receive and send data, and the memory is configured to store program code, and the processor is configured to execute the program code, and when the processor executes the program code stored in the memory, the processor is enabled to perform the power adjustment method according to claim 8. ### Claim 34 (canceled)
