Abstract

The invention discloses a method and a device for transceiving feedback information of downlink data. Under the circumstance that short time slot is adopted on a network side to transmit data, UE is enabled to feed back received data as soon as possible, so that RTT time is shortened, user plane time delay is lowered, and system performance is improved. The method includes that the user equipment (UE) receives downlink data sent by the network side using the time slot as a unit, and the UE sends feedback information of the downlink data to the network side by using subframe or time slot as a unit, wherein the time slot is a time unit less than 1 millisecond in duration.

Description

A kind of transmission of the feedback information of downlink data and receiving handling method, device

Technical field

The present invention relates to communication technical field, more particularly, to a kind of transmission of the feedback information of downlink data and connecing Receiving processing method, device.

Background technology

With the development and change of mobile communication business demand, multiple tissue such as International Telecommunication Union (itu) is right Future mobile communication system both defines higher user plane delay performance and requires.During in order to reduce user plane Prolong, shorter transmission time unit time slot can be introduced) (less than 1ms) carry out data transmission, from And reduce process time and the slot transmission time of base station and user equipment (user equipment, ue). If still feeding back sequential using existing downlink data, can make the ue can not be in time to the lower line number receiving According to being fed back.

Frame structure in Long Term Evolution (long term evolution, lte) system is described below.

In lte system, FDD (frequency division duplex, fdd) pattern and when Duplexing (time division duplex, tdd) pattern is divided to be all radio frames 10ms, a subframe 1ms.For the radio frames of each tdd pattern, define seven kinds of tdd uplink-downlink configuration, specific as follows Shown in the table 1 in face, wherein d represents descending (dl) subframe, and u represents up (ul) subframe, s generation The special subframe of table tdd system.Downlink data transmission in lte subframe uses 1ms time slot.

Table 1 tdd uplink-downlink configuration

It is described below with regard to the downstream feedback sequential in lte system:

In lte fdd system, ue receives downlink data in subframe n-4, anti-in sub-frame of uplink n Present the signaling the need of re-transmission for the data on this descending sub frame, that is, confirm (ack) or non-acknowledgement (nack) Information, wherein, n is the integer more than or equal to 4.

In lte tdd system, ue may feed back corresponding to multiple descending sub frames in same sub-frame of uplink Ack or nack information, that is, ue detect physical down link sharing channel in descending sub frame n-k (physical downlink shared channel, pdsch) transmission or indicating downlink semi-continuous scheduling The Physical Downlink Control Channel (physical downlink control channel, pdcch) of release, Feed back corresponding ack or nack information, wherein k ∈ k in sub-frame of uplink n, the value of set k with The uplink-downlink configuration of system and specific subframe number are relevant, as shown in Table 2 below.Particularly, for Special subframe, configures 0 and 5 when employing conventional cyclic prefix (cyclic prefix, cp) special subframe And during extension cp special subframe configuration 0 and 4, special subframe no ack or nack feeds back, i.e. ue Ack or nack is not fed back to special subframe.

Table 2 tdd descending correlation k value: k:{ k₀,k₁,…k_m-1}

Table 2 reflect tdd uplink-downlink configuration instruction down mixing self-retransmission (hybrid-arq, Harq) feed back sequential relationship.In lte system, multiple wireless frame sequential arrangements, only with one in table 2 The situation of the k corresponding to each sub-frame of uplink is given, wherein n-k < 0 expression is previous as a example individual radio frames The individual descending sub frame of inverse | n-k | in radio frames, for example the up son, when n=2, k=6, in radio frames a Frame 2 carries the corresponding ack or nack information of descending sub frame 6 in radio frames a-1.Wherein, a is Integer more than or equal to 1.

It is described below with regard to the two-way time (round trip time, rtt) in lte system:

Rtt is defined as the deadline of a transmission of data packets during harq, including from one Packet starts to send in transmitting terminal, after receiving terminal reception processing, feeds back ack or nack according to result After signaling, transmitting terminal demodulation process ack or nack signal, determine that next frame is retransmitted or transmitted new Packet overall process.As shown in fig. 1, wherein tp is one way propagation time delay, and tue receives for ue Processing delay to after downlink data block, tenb connects for evolved base station (evolved node b, enb) Receive the processing delay after ue feedback.Tdelay1 is that in tdd frame structure, ue has processed downlink transfer After block, time of having to wait for a nearest ascending time slot；Tdelay2 is enb in tdd frame structure After having processed ue feedback, time of having to wait for a nearest descending time slot.

Fdd system has unified rtt, and the rtt of tdd system is relevant with specific uplink-downlink configuration.

The ue plane time delay of lte system is handled by the base station time, frame time alignment, slot time and ue Process time four part is constituted, and wherein frame time alignment is obtained in that for business to the business of reaching subframe of eating dishes without rice or wine passes Waiting time between defeated chance.If it is considered that when the harq of system retransmits, the ue plane of lte system Time delay also includes data and retransmits the shared time.

In sum, using when gap is transmitted in short-term in existing lte system, due to once transmit Packet is less, and ue can be demodulated to the packet receiving faster, if still using existing Downlink data feedback sequential, ue can be made can not in time the downlink data receiving to be fed back.
