Description
Technical field
The present invention relates to the communications fields, in particular to a kind of uplink and downlink resource allocation information processing method and processing device.
Background technique
Time division duplex (Time Division Duplex, referred to as TDD) system (is issued in temporal partitioning uplink by terminal
Base station) and downlink (terminal is issued by base station) resource, and dividing for uplink and downlink resource is carried out usually as unit of time slot or subframe
Match.Under normal circumstances, base station is notified the distribution condition of uplink and downlink resource to cell using broadcast signaling in semi-static mode
Interior all terminals.
Fig. 1 is the frame of long term evolution (Long Term Evolution, referred to as LTE) system TDD mode in the related technology
Structural schematic diagram, as shown in Figure 1, wherein the frame structure is also known as the second class frame structure, (i.e. frame structure
Type2).In the frame structure, the nothing of one 10 milliseconds (i.e. 307200Ts, Ts are sampling interval, 1Ts=1/30720000 second)
Line frame is divided into two fields, 5 milliseconds of each half frame length (i.e. 5ms).Each field includes the subframe that 5 length are 1ms.Table 1
For 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 represents the downlink subframe for being used for transmission downlink signal.U represents the sub-frame of uplink for being used for transmission uplink signal.
One upstream or downstream subframe is divided into the time slot of 2 0.5ms again.S represents special subframe, includes three special time slots, i.e. downlink
Pilot time slot (Downlink Pilot Time Slot, referred to as DwPTS), is used for transmission downlink signal, protection interval
(Guard Period, referred to as GP) and uplink pilot time slot (Uplink Pilot Time Slot, referred to as UpPTS) are used
In transmission uplink signal.
The downlink of LTE system uses orthogonal frequency division multiplexing (Orthogonal Frequency Division
Multiplexing, referred to as OFDM) technology, uplink use single-carrier frequency division multiple access (Single Carrier-Frequency
Division Multiple Access, referred to as SC-FDMA) technology (or being DFT Spread-OFDM technology).Common
CP(normal cyclic prefix) under the conditions of, a time slot is made of 7 OFDM symbols or SC-FDMA symbol.It is extending
CP(Extended cyclic prefix) under the conditions of, a time slot is made of 6 OFDM symbols or SC-FDMA symbol.Fig. 2 is
In the related technology corresponding to common CP downlink subframe when, frequency-domain structure schematic diagram.As shown in Fig. 2, a resource element
The bandwidth of (Resource Element, referred to as RE) is 15kHz, accounts for an OFDM or SC-FDMA symbol in the time domain.One
Resource block (Resource Block, referred to as RB) accounts for 12 RE on frequency domain, occupies a time slot in the time domain.
LTE system by Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as
PDSCH downstream data traffic) is sent, Physical Uplink Shared Channel (Physical Uplink Shared Channel, letter are passed through
Referred to as PUSCH) send upstream data service.In addition, LTE physical layer further comprises some control channels, for assisting uplink and downlink
Data transmission.Some control channels included by LTE physical layer are illustrated below.
Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH) or enhancing
Physical Downlink Control Channel (Enhanced Physical Downlink Control Channel, referred to as EPDCCH), on
The two is stated for carrying at least one following control information: uplink scheduling signaling is (for example, Downlink Control
Information (DCI) format0/4).The signaling is used to indicate terminal uplink resource allocation conditions, and the modulation of transmission block is compiled
The information such as code mode；Descending scheduling signaling (for example, DCI format1/1A/1B/1C/1D/2/2A/2B/2C/2D).The signaling
It is used to indicate user equipment downlink resource allocation conditions, the information such as modulation coding scheme of transmission block；Uplink power control signaling (example
Such as, DCI3/3A).The signaling is used to indicate the adjustment situation of terminal uplink transmission power.
Physical mixed ARQ instruction channel (Physical Hybrid ARQ Indicator Channel, referred to as
PHICH), whether correct it is used to indicate transmitting uplink data result.
In LTE system, uplink and downlink data, which transmit corresponding control signaling, certain sequential relationship.PDSCH's
(it is assumed that sending on subframe n), (ACK/NACK is used for the feedback signaling of PDSCH in the same subframe by dispatch and PDSCH
Whether designation date is correctly transmitted) it is sent on the subframe n+k after PDSCH.PUSCH is sent on subframe m, dispatch
It is sent on subframe m-p before, feedback signaling (ACK/NACK) is sent on subframe m+q later.
In some wireless communication scenes, the uplink and downlink business variation in base station service area is very violent.For example, one
In a little cells (small cell) or home environment, the number of users of base station service is seldom, and system load is relatively low, service
The ratio of uplink and downlink data volume changes quickly in area.In such a situa-tion, semi-static distribution TDD system uplink and downlink resource
Affect the efficiency of resource allocation.In this context, LTE R12 version is that tdd mode introduces the configuration of dynamic uplink and downlink
Adjust function.The problem that function needs solve is: how base station quickly notifies terminal current area to use upper and lower
Row configuration?
System information block (System Information Block, referred to as SIB)/wireless heterogeneous networks (Radio
Resource Control, referred to as RRC)/media access control (Medium Access Control, referred to as MAC) is contour
The period of layer signaling is long, delay is big, and there are execute the moment to signaling between terminal and base station to understand differently the mould of cause
Paste problem, therefore it is not able to satisfy the requirement of uplink and downlink dynamic recognition.Notify that uplink and downlink configuration is mesh by physical layer signaling
The hot spot of preceding discussion, main advantage are that delay is small, and fuzzy problem is not present.However use physical layer signaling there is also with
Lower disadvantage: it needs to occupy additional physical layer resources, thus increases physical layer control signaling expense.In addition, increasing new object
Reason layer signaling can also improve the implementation complexity of equipment.
Therefore, uplink and downlink are configured under the situation for carrying out dynamic adjustment in the related art, is realized using high-level signaling
When, there are period length, delays to execute inconsistent problem to signaling greatly and between terminal and base station, and physical layer is used to believe
It enables when realizing, and there are physical layer control signaling expense is big, the high problem of equipment implementation complexity.
