A transmission resource obtaining method, comprising: receiving first configuration information sent by a base station, and obtaining request resources based on the first configuration information, wherein the request resources comprise a scheduling request SR resource and a physical random access channel PRACH resource; determining a target request resource from the request resources based on time information of user equipment, wherein the target request resource comprises the SR resource and/or the PRACH resource; and sending an uplink resource request to the base station by using the target request resource; wherein the sending an uplink resource request to the base station by using the target request resource comprises: if the target request resource is the SR resource, sending an SR to the base station by using the SR resource; or if the target request resource is the PRACH resource, sending a preamble to the base station by using the PRACH resource, characterized in that the obtaining request resources based on the first configuration information comprises: if learning, based on the first configuration information, that the request resources belong to a first-type cell, obtaining the request resources from the first-type cell; or if learning, based on the first configuration information, that the PRACH resource belongs to a first-type cell and the SR resource belongs to a second-type cell, respectively obtaining the request resources from the first-type cell and the second-type cell, wherein the first-type cell comprises a cell in which clear channel assessment CCA detection needs to be performed before to-be-transmitted data is sent, and the second-type cell comprises a cell in which clear channel assessment CCA detection does not need to be performed before to-be-transmitted data is sent. receiving first configuration information sent by a base station, and obtaining request resources based on the first configuration information, wherein the request resources comprise a scheduling request SR resource and a physical random access channel PRACH resource;
