Description
Technical field
The present invention relates to wireless communication technology in the communications field, particularly, relate to method, base station, terminal and the system of dynamic slot proportioning.
Background technology
One, LTE-Advanced TDD time slot proportion
For LTE-A TDD carrier wave, need the configuration uplink and downlink timeslot ratio.At present, the standards such as 3GPP 36.300 are supported the uplink and downlink timeslot proportioning of 7 kinds of different proportions altogether, and are as shown in the table:
D sign descending time slot in upper table, U identifies ascending time slot, S sign special time slot (being used for the conversion between upstream and downstream).For example, if a TDD carrier wave has been configured the time slot configuration mode No. 3, this carrier wave is in the radio frames of a 10ms, its the 0th work song frame and be descending time slot No. 5-9, be used for the base station to the transfer of data of terminal, its the 1st work song frame is used for special time slot, and its 2nd, 3 and 4 work song frame is ascending time slot, is used for the transfer of data of terminal to base station.
When 1 carrier wave of terminal access communicates, need at first to know the time slot proportion information of this carrier wave by the system information that reads carrier wave, then carry out uplink and downlink communication according to this time slot proportioning information.
Two, terminal dynamic slot
Because the terminal supporting business is abundant, a kind of fixing time slot proportion scheme can't adapt to abundant traffic performance, for example the expectation of voice service uplink and downlink timeslot proportioning is 1: 1, Online Video is watched business expectation time slot proportion is descending and is dominant, and uses for some Internet of Things and expects that the ascending time slot proportioning is dominant.Therefore, adapt to different business demands if can dynamically adjust the uplink and downlink timeslot proportioning of terminal, the user experiences and network resource utilization all benefits for improving.
According to prior art, if terminal will be supported dynamic time slot proportion scheme, when namely supporting to be not limited to flexibly the uplink and downlink timeslot mix proportion scheme of configuration in above 7, only have one of the following dual mode of employing:
Scheme one:
1) be a plurality of carrier waves of terminal configuration, and different carrier need to configure different time slot proportion;
2) terminal must have the two above RF receiving/transmission devices of cover and guarantees to be supported in simultaneously uplink and downlink communication on different carrier;
3) terminal accesses a plurality of carrier waves by the mode of carrier aggregation, and because each carrier wave adopts different time slot proportion, so terminal has realized that by the carrier wave of polymerization different time-gap proportioning self uplink and downlink timeslot proportioning is not limited to the target among above-mentioned 7 kinds of configurations.For example, and No. 0 time slot proportion of carrier wave 1 employing (U: D=6: 2), No. 2 time slot proportion of carrier wave 2 employings (U: D=2: 6), if these two carrier waves of terminal polymerization can be realized time slot proportion (U: D=1: 1).
Scheme two:
According to terminal requirements, dynamically adjust the uplink and downlink timeslot proportioning of carrier wave.
The major defect of existing scheme one is, needs the RF receiving/transmission device of terminal support at least 2 covers, and is larger to the terminal cost impact;
If dynamically adjust carrier wave uplink and downlink timeslot proportioning according to existing scheme two, due to the adjacent area interference problem, require the whole network synchronously to adjust, huge to web influence, and can't realize the proportioning of subregion different time-gap.
