Description
Technical field
The present invention relates to wireless communication technology field, a kind of method that particularly semi-persistent resource of discrete narrow band system is synchronous, base station and terminal.
Background technology
The design of the discrete narrow band system in radio communication is limited to available band situation, unlike system of distributing bandwidth continuously and on a large scale, and the control channel of all kinds of large bandwidth of design that can be more calm and Traffic Channel.Owing to being discrete narrow band system, consider the electricity-saving characteristic of terminal and the bandwidth ability of radio-frequency filter, and consider the Cost Problems of terminal in actual product, there is great amount of terminals only to support to carry out control channel in narrow bandwidth range, especially the monitoring of authorization channel and reception, and single terminal is once dispatched and is only supported in a discrete narrow band resource enterprising industry business transmission.So for discrete narrow band system, general mode of operation is that terminal selects some discrete frequencies to monitor the frequency of authorization control channel as idle period, becomes resident frequency.After resident frequency has listened to the authorization message of oneself, then according to the frequency resource of wherein distributing, jump to specific frequency enterprising industry business transmission, this frequency becomes working frequency points.If terminal jumps to after in working frequency points, also have mandate to receive, then continue to issue mandate in working frequency points.
For discrete narrow band system, less just because of available resources, so in order to improve resource utilization as far as possible, often adopt semi-static transmission, instead of dynamic dispatching transmission.Namely terminal monitors authorization channel on residence sub-band, the discrete frequency resource of authorizing the transmission of indicating terminal business is opened in the once scheduling received from base station, then terminal is transmitted on the resource continuously, do not need to receive subsequent authorization again, until business end of transmission, then base station issues scheduling again and closes mandate, and indicating terminal releasing resource, gets back to residence sub-band.And simultaneously, due to the error of transmission of reality in communication system, also deposit base station and the nonsynchronous problem of SOT state of termination.If the scheduling resource that base station issues is opened to authorize or close and is authorized, terminal does not receive correctly, meanwhile authorize corresponding terminal feedback also in base station side also parse error, or simple mandate feedback is at base station side parse error, capital causes base station and terminal, on scheduling resource successful, misjudgment occurs, and causes asynchronous in resource of base station and terminal.
