Abstract:
1. A method for data transmission, comprising: receiving, by a device, a paging message; determining, by the device, a time window for acquiring an uplink transmission resource based on a subframe for receiving the paging message; acquiring, by the device, the uplink transmission resource at the time window for acquiring the uplink transmission resource; and reporting, by the device, user data in the uplink transmission resource, by using a time advance value that is stored in the device and that corresponds to a current position value, wherein when the uplink transmission resource is allocated to the device by a base station and the device is a Machine Type Communications (MTC) device, determining, by the MTC device, the time window for acquiring the unlink transmission resource based on the subframe for receiving the paging message comprises determining that the time window for acquiring the uplink transmission resource is based on summing a subframe of the paging message or a subframe indicated by the paging message, a fixed offset, and a multiple of an index number of the MTC device in a paging list, wherein the multiple is a number of subframes spaced between uplink schedules of two MTC devices; or wherein when the device is a device in a paging group, and the uplink transmission resource is allocated to the paging group by a base station, determining, by the device, the time window for aquiring the uplink transmission resource based on the subframe for receiving the paging message comprises identifying a time window after a fixed interval as the time window for acquiring the uplink transmission resource; or wherein determining, by the device, the time window for acquiring the uplink transmission resource, comprises: determining, by the device, a start position of the time window for acquiring the uplink transmission resource; wherein the device is an MTC device; wherein the start position of the time window is based on summing a subframe of the paging message or a subframe indicated by the paging message, a fixed offset, and a size of the time window multiplied by an index number of the MTC device in an paging list; and wherein the uplink transmission resource is an uplink transmission resource allocated to the MTC device by a base station.
