Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for configuring a special timeslot in a time division duplex system.
Background
A frame structure of a TDD (Time division duplex) mode of an LTE (Long Term Evolution) system is shown in fig. 1. In this frame structure, a 10ms radio frame is divided into two half-frames, each of which is divided into 10 slots (numbered from 0 to 9) of length 0.5ms, the two slots constituting a subframe of length 1ms, and one half-frame containing 5 subframes (numbered from 0 to 4). For short CP (Cyclic Prefix) lengths of 5.21us and 4.69us, a slot contains 7 symbols of length 66.7us, where the first symbol CP length is 5.21us and the remaining 6 symbols CP length is 4.69 us; for a long CP of length 16.67us, one slot contains 6 symbols. In addition, in the frame structure, the configuration characteristics of the sub-frame are as follows:
subframe 0 is fixed for downlink;
subframe 1 (hereinafter referred to as a special subframe) includes 3 special timeslots, which are DwPTS (Downlink Pilot Time Slot), GP (Guard Period), and UpPTS (Uplink Pilot Time Slot). Wherein,
↓DwPTSis used for descending, at least one symbol is used for transmitting main synchronous channel
P-SCH (Primary-Synchronization Channel, Primary Synchronization Channel),
when the DwPTS contains multiple symbols, the P-SCH is placed on the first symbol (as shown in fig. 1);
the ↓ GP is protection time and does not transmit any data;
the ↓upptsis used for uplink, and may be used to transmit signals such as RACH (Random access channel), data, sounding pilot, and the like.
The first n subframes behind the subframe 1 are used for uplink transmission (n is more than or equal to 1 and less than or equal to 3), and the last 3-n subframes are used for downlink transmission.
When the coexistence of the LTE TDD system, the TD-SCDMA (Time-Division synchronous Code Division Multiple Access) system (frame structure is shown in fig. 2) and the TD-CDMA (Time-Division Code Division Multiple Access) system (frame structure is shown in fig. 3) is considered, if the ratio configuration of the uplink and downlink subframes is not reasonable or the Time length configuration of three special Time slots (DwPTS, GP, and UpPTS) is not reasonable, the LTE system and the TD-SCDMA system cannot realize the adjacent frequency coexistence.
