Description
Technical field
The present invention relates to the communications field, in particular to a kind of up-downgoing resource allocation information processing method and device.
Background technology
Time division duplex (Time Division Duplex, referred to as TDD) system is divided up (issuing base station by terminal) and descending (issuing terminal by base station) resource in time domain, and conventionally take time slot or subframe and carry out the distribution of uplink and downlink resource as unit.Generally, base station utilizes broadcast signaling that the distribution condition of uplink and downlink resource is notified to all terminals in community in semi-static mode.
Fig. 1 is the frame structure schematic diagram of the medium-term and long-term evolution of correlation technique (Long Term Evolution, referred to as LTE) system TDD mode, and as shown in Figure 1, wherein, this frame structure is called again Equations of The Second Kind frame structure, (being frame structure type2).In this frame structure, the radio frames of 10 milliseconds (be 307200Ts, Ts is the sampling interval, 1Ts=1/30720000 second) is divided into two fields, 5 milliseconds of each half frame lengths (being 5ms).Each field comprises the subframe that 5 length are 1ms.Table 1 is the effect of each subframe in uplink-downlink configuration in LTE system, as shown in table 1,
The configuration of table 1LTE uplink and downlink
Wherein, D representative is for the descending sub frame of transmission of downlink signal.U representative is for transmitting the sub-frame of uplink of upward signal.A upstream or downstream subframe is divided into again the time slot of 2 0.5ms.S represents special subframe; comprise three special time slots; be descending pilot frequency time slot (Downlink Pilot Time Slot; referred to as DwPTS); for transmission of downlink signal, protection interval (Guard Period; referred to as GP) and uplink pilot time slot (Uplink Pilot Time Slot, referred to as UpPTS), for transmitting upward signal.
The descending use OFDM of LTE system (Orthogonal Frequency Division Multiplexing, referred to as OFDM) technology, up use single-carrier frequency division multiple access (Single Carrier – Frequency Division Multiple Access, referred to as SC-FDMA) technology (or being called DFT Spread – OFDM technology).Under common CP (normal cyclic prefix) condition, a time slot is comprised of 7 OFDM symbols or SC-FDMA symbol.At expansion CP(Extended cyclic prefix) under condition, a time slot is comprised of 6 OFDM symbols or SC-FDMA symbol.Fig. 2 be in correlation technique corresponding to the descending sub frame of common CP time, frequency-domain structure schematic diagram.As shown in Figure 2, the bandwidth of a resource element (Resource Element, referred to as RE) is 15kHz, accounts for an OFDM or SC-FDMA symbol in time domain.A Resource Block (Resource Block, referred to as RB) accounts for 12 RE on frequency domain, takies a time slot in time domain.
LTE system is by Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as PDSCH) transmission downstream data traffic, by Physical Uplink Shared Channel (Physical Uplink Shared Channel, referred to as PUSCH), send upstream data service.In addition, LTE physical layer has also comprised some control channels, for auxiliary uplink and downlink transfer of data.Below some included control channels of LTE physical layer are described.
Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH) or strengthen Physical Downlink Control Channel (Enhanced Physical Downlink Control Channel, referred to as EPDCCH), above-mentioned both for carrying following control information one of at least: uplink scheduling signaling (for example, Downlink Control Information (DCI) format0/4).This signaling is used to indicate terminal ascending resource distribution condition, the information such as the modulation coding mode of transmission block; Descending scheduling signaling (for example, DCI format1/1A/1B/1C/1D/2/2A/2B/2C/2D).This signaling is used to indicate terminal downlink resource distribution condition, the information such as the modulation coding mode of transmission block; Uplink power control signaling (for example, DCI3/3A).This signaling is used to indicate the adjustment situation of terminal uplink transmission power.
Whether correct physical mixed ARQ indicating channel (Physical Hybrid ARQ Indicator Channel, referred to as PHICH), be used to indicate transmitting uplink data result.
In LTE system, the uplink and downlink transfer of data control signal corresponding with it has certain sequential relationship.The dispatch of PDSCH and PDSCH, in the upper transmission of same subframe (being assumed to subframe n), send on the subframe n+k of the feedback signaling of PDSCH (whether correctly ACK/NACK is used to indicate data transmission) after PDSCH.PUSCH sends on subframe m, and its dispatch sends on subframe m-p before, feedback signaling (ACK/NACK) after subframe m+q on send.
In some radio communication scenes, the uplink and downlink business in base station service area changes very violent.For example, in some small-cells (small cell) or home environment, seldom, system load is lower for the number of users of a base station service, and in service area, the ratio of uplink and downlink data volume changes very fast.Under such condition, semi-static distribution T DD system uplink and downlink resource has affected the efficiency that resource is distributed.Under such background, LTE R12 version is that tdd mode has been introduced dynamic uplink and downlink configuration adjustment function.The problem that this function need to solve: the base station uplink and downlink configuration how fast notification terminal current area is used?
System information block (System Information Block, referred to as SIB)/Radio Resource control (Radio Resource Control, referred to as RRC)/media access control (Medium Access Control, referred to as MAC) cycle of contour level signaling is long, it is large to postpone, and there is the fuzzy problem that between terminal and base station, execution constantly understands differently and causes to signaling, therefore can not meet the requirement of uplink and downlink dynamic recognition.By physical layer signaling, notifying uplink and downlink configuration is the focus of discussing at present, and its main advantage is that delay is little, and does not have fuzzy problem.Yet use physical layer signaling also to have following shortcoming: to need the physical layer resources outside occupying volume, thereby increased physical layer control signal expense.In addition, increase new physical layer signaling and also can improve the implementation complexity of equipment.
Therefore, under the situation that configuration is carried out dynamically adjusting to uplink and downlink in correlation technique, while adopting high-level signaling to realize, there is cycle length, postpone greatly, and between terminal and base station, signaling is carried out to inconsistent problem, and while adopting physical layer signaling to realize, exist again physical layer control signal expense large, the problem that equipment implementation complexity is high.
