However, it will be apparent to one of ordinary skill in the art that the present disclosure may be practiced without these specific details.

These and other features and characteristics of the present disclosure, as well as the methods of operation, functions of the related elements of structure, combinations of parts and economies of manufacture, may be better understood with reference to the following description and the accompanying drawings, all of which form a part of this specification. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended as a definition of the limits of the disclosure. It will be understood that the figures are not drawn to scale.
Various block diagrams are used in the present disclosure to illustrate various modifications of the embodiments according to the present disclosure. It should be understood that the foregoing or following structures are not intended to limit the present disclosure. The protection scope of the present disclosure is subject to the claims.
In the prior art, a wireless communication system based on multiple carriers organizes data transmission by data frames, that is, at least one space-time resource of a data frame is occupied in one transmission, which also means that the transmission delay of the system cannot be less than one frame. Further, a multi-user scheduling system requires a scheduling signaling to indicate the resources each user transmits to; as shown in fig. 1, one data frame includes 10 data frames, wherein the first OFDM symbol (ofdm#1) is scheduling signaling; resources of a plurality of NT (Network terminal) nodes (hereinafter referred to as NTs) (e.g., NTs 1 to NT 3) are allocated on different carriers. This means that, assuming that the duration of one OFDM symbol is ts+tcp (where Ts is the symbol length and Tcp is the length of the cyclic shift), the delay of one transmission is not less than 10 (ts+tcp). However, this delay is still too high at this time relative to other low delay transmissions.
In a 3 GPP-defined 5G communication system, a frame is allowed to flexibly use different numbers of OFDM, thereby reducing transmission delay. For example, if one short data frame occupies only one OFDM symbol and a part of carriers are used to transmit scheduling signaling and other carriers are used to transmit data, the transmission delay can be reduced to ts+tcp, as shown in fig. 2. The use of a frame of a single OFDM symbol can reduce the transmission delay, however this also means that the delay cannot be further compressed, since the length of the single OFDM symbol is typically fixed at this time. For low latency and highly reliable communication systems, the latency requirements for the transmission of some small data are as small as possible. The method in fig. 2 cannot further shorten the transmission delay, the transmission efficiency is reduced, and the accuracy is greatly reduced; there is a need for a low latency data communication method.
The embodiment of the disclosure provides a data communication method, as shown in fig. 3, specifically including:
s101, receiving a resource allocation signaling;
s102, performing blind detection on the resource allocation signaling;
and S103, when the resource allocation signaling is successfully identified through the blind detection, the receiving/sending of the data packet to be transmitted is completed according to the resource allocation signaling.
In some embodiments, performing blind detection on the resource allocation signaling specifically includes: and carrying out blind detection on the resource allocation signaling through different carrier spacing.
In some embodiments, the different carrier spacing includes at least a wide carrier spacing and/or a normal carrier spacing.
In some embodiments, the different carrier spacing includes a blank spacing therebetween.
In general, the symbol length and carrier spacing of OFDM satisfyIn whichIs the length of the OFDM symbol,is the carrier spacing and is therefore largerMeaning a shorter symbol length; however, a shorter symbol length also means more CP (Cyclic Prefix) overhead, so that a typical OFDM system does not select a particularly short symbol length, but in a low-latency system applied in the present invention, spectrum resources are rich, and transmission of some small data packets may need as low latency as possible.
Specifically, data transmission can be performed using different carrier pitches within one frame, and the carrier pitches need to satisfy a multiple increase relationship with each other, for example, a common carrier pitch is 15kHz, and other carrier pitches are 30kHz, 60kHz, and the like.
Further, the symbol with wide carrier spacing occupies at least the first N OFDM symbols of one frame; at this time, at the first N symbols of one frame, the transmission delay will be shortened, but if the CP of the same length is maintained, this means that a certain blank transmission phase, i.e. a blank interval, needs to be reserved to keep the length of the whole frame unchanged. In a specific transmission, if the wide carrier symbol requires a pre-signaling indication, this means a longer delay, so it is necessary to support the configuration of the frame change at any time by the transmitting end (NC node), and the receiving end can recognize the transmission. The specific sending and receiving flow is as follows:
in some embodiments, if a short-delay data packet to be transmitted arrives at the NC node, the NC node configures the first N frames as required to be wide carrier frames, and sends a resource allocation signaling in the first symbol.
Further, the NT node will perform blind detection of different frame configurations in the first frame, will attempt to detect the resource allocation signaling according to different carrier spacing; and when the detection on the wide carrier is successful, the detection, the receiving and the sending of the whole data packet are finished according to the configuration information.
As shown in fig. 4, the NC node transmits a packet to the NT1 node and the NT2 node, wherein the NT1 node transmits using a wide carrier spacing, that is, means 3 short OFDM (e.g.The symbol=30khz) transmits the data of the NT1 node, while the data of the NT2 node is transmitted in the next 7 normal OFDM symbols (e.g.=15 kHz).
Further, both NT1 node and NT2 node perform blind detection, i.e. perform blind detection on the resource allocation signaling through different carrier spacing, i.e. attempt to detect short symbols and common symbols. The NT1 node and the NT2 node successfully identify the configuration signal in the short symbol, so that the NT2 node starts to perform signal detection after the blank interval is ended, and the NT1 completes the reception of the data by using the short OFDM symbol. The blank interval is generated because at the short OFDM symbol, the CP length still needs to be the same as the normal symbol CP, which means that the CP duty ratio of 3 short OFDM symbols becomes large, and one normal OFDM symbol needs to be wasted to keep the fixed length of the whole frame; meanwhile, the blank interval is also favorable for switching by using processing modules with different symbol lengths. For example, NT1 may also receive other data packets at the same time at the normal OFDM symbol (ofdm#4-ofdm#10).
In some embodiments, the method further comprises: the resource allocation signaling also includes the configuration situation of one or more NT nodes in the current uplink frame.
In some embodiments, the method further comprises: if the resource allocation signaling only includes the configuration of one NT node in the current uplink frame, the NT node may change the resource allocation signaling and notify the NC node.
In some embodiments, the method further comprises: and if the resource allocation signaling comprises the configuration condition of a plurality of NT nodes in the current uplink frame, configuring protection resources in the resource allocation signaling.
Specifically, for an upstream frame, that is, when a packet to be transmitted arrives at the NT node, the NT node cannot directly change the configuration of the current frame, because there is a possibility that multiple NT nodes also occupy the frame. At this time, the NC node may broadcast the configuration of all NT nodes of the current uplink frame in the downlink configuration signaling. When one NT node recognizes that the current frame is configured only by itself, the current frame can be directly modified; the short symbols may be used on the frequency resources configured by the NC node if the NT node identifies that the current frame has other NT nodes. The configuration resource may be configured by the NC node in advance, and configure the null carrier as a guard band.
As shown in fig. 5, only the NT1 node is configured for uplink transmission in the current frame, the NT1 node uses a short OFDM symbol with a wide carrier spacing for transmission, and transmits the modified resource allocation signaling to the NC node in the first symbol; the NC node performs blind detection on the received resource allocation signaling, and identifies that the NT1 node selects a short OFDM symbol from the resource allocation signaling for transmission; since the NT2 node is not configured to transmit, the short symbol transmission of the NT1 node does not cause any inter-carrier interference.
As shown in fig. 6, both NT1 node and NT2 node have uplink transmissions in the current frame. But the NT1 node arrives at the delay sensitive traffic, so the NT1 node chooses to transmit short symbols on the reserved resources (upper left side of fig. 6), and 2 guard carriers are configured between the reserved resources and the normal resources. The NT2 node still transmits on the common symbol scheduled by the NC node. Because different symbol lengths are used, the NT1 node transmission will leak a certain amount of interference to the adjacent carriers, but the protected carriers are less interfered, so that normal receiving/transmitting data of the NT2 node signal is not affected. It should be noted that, when the NC node schedules the NT1 node and the NT2 node, the NC node configures both the normal resource and the short symbol resource to avoid interference; although this configuration wastes certain spectrum resources, the transmission delay of emergency services can be greatly reduced.
The embodiment of the disclosure discloses a data communication method, which ensures the number of subcarriers on one hand by planning subcarriers with smaller intervals, namely enhances the flexibility of subcarrier planning by reducing the granularity of the subcarriers; and on the other hand, the minimum message transmission delay is compressed, so that the real-time performance of the communication system is improved.
