Description

Method for transmitting and receiving data, network device and terminal device

Technical Field

Embodiments of the present disclosure relate to the field of wireless communications, and more particularly, to a method, a network device, and a terminal device for transmitting and receiving data.

Background

Network slicing (network slicing) is the key of the fifth generation (5G) mobile communication technology. The end-to-end network slicing capability provided by the 5G network can flexibly and dynamically distribute required network resources in the whole network facing different requirements and release the capability, further dynamically optimize network connection, reduce cost and improve benefit.

Network slicing techniques divide a physical network into multiple virtual end-to-end networks for different types of services. The different types of services, such as massive low power consumption connectivity (mtc), enhanced mobile broadband (eMBB) service, and low latency high reliable connectivity (mtc) service, have different characteristics and requirements in terms of data rate, latency, reliability, connectivity volume, and the like. Therefore, there is a need for a flexible air interface frame that can have multiple Transmission Time Intervals (TTIs) to support slicing of different latency requirements.

Detailed Description

Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure have been illustrated in the accompanying drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.

The term "network device" as used herein refers to a base station or other entity or node having a particular function in a communication network. A "base station" may represent a node B (NodeB or NB), an evolved node B (eNodeB or eNB), a Remote Radio Unit (RRU), a Radio Head (RH), a Remote Radio Head (RRH), a relay, or a low power node such as a pico base station, a femto base station, or the like. In the context of the present disclosure, the terms "network device" and "base station" may be used interchangeably for ease of discussion purposes, and refer primarily to an eNB as an example of a network device.

The term "terminal device" as used herein refers to any terminal device or User Equipment (UE) capable of wireless communication with a base station or with each other. As an example, the terminal device may include a sensor having a communication function, a detector, a Mobile Terminal (MT), a Subscriber Station (SS), a Portable Subscriber Station (PSS), a Mobile Station (MS), or an Access Terminal (AT), and the above-described devices in a vehicle, and the like. In the context of the present disclosure, the terms "terminal device" and "user equipment" may be used interchangeably for purposes of discussion convenience, and UE is primarily taken as an example of a terminal device.

The terms "include" and variations thereof as used herein are inclusive and open-ended, i.e., "including but not limited to. The term "based on" is "based, at least in part, on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment". Relevant definitions for other terms will be given in the following description.

Fig. 1 illustrates a schematic diagram of an exemplary communication scenario 100 in which embodiments of the present disclosure may be implemented. For ease of discussion, the eNB will be taken as an example of a network device or base station and the UE as an example of a terminal device. It should be understood, however, that this is done merely for convenience in explaining the concepts of the embodiments of the present disclosure and is not intended to limit the application scenarios or scope of the present disclosure in any way.

In the example shown in fig. 1, eNB 110 may transmit data to multiple UEs (e.g., uMTC UE 121, eMBB UE 122, mtc UE 123) with different service types, such as uMTC services, eMBB services, mtc services, and so on. As mentioned earlier, these services have different characteristics and requirements in terms of data rate, delay, reliability, connection capacity, etc. For example, for a uMTC service, an eMBB service, and an mtc service, TTIs of 0.25ms, 0.5ms, and 1ms need to be used for data transmission, respectively.

As is known, different TTIs have different resource allocation periods. For example, the mtc service requires an allocation period of 0.25ms to meet its low latency requirement. For eMBB services and mtc services, allocation periods of 0.5ms and 1ms are sufficient to meet their latency requirements. A long allocation period may reduce additional resource overhead and baseband processing costs compared to a short allocation period. In this case, a flexible air interface frame is needed, which can have multiple TTIs in order to meet the UE requirements with different latency requirements.

Fig. 2 shows a time-frequency diagram of air interface frames with different TTIs according to an embodiment of the disclosure. As shown in fig. 2, 210 (indicated by diagonal lines) may correspond to a uMTC slice for data transmission for the uMTC UE 121 with a TTI of 0.25ms in fig. 1, with 0-11 slots exemplarily shown. 220 (indicated by the diagonal cross-hatched lines) may correspond to an eMBB slice for data transfer for an eMBB UE 122 with a TTI of 0.5ms in fig. 1, with 0-5 slots exemplarily shown. 230 (indicated by orthogonal network lines) may correspond to mtc slices for data transmission for mtc UEs 123 with a TTI of 0.5ms in fig. 1, with 0-2 slots exemplarily shown.

When there are different TTIs, i.e. different resource allocation periods, in one frame structure, enough resources should be reserved for time sensitive slices (e.g. low latency uMTC slices 210) since air interface resources need to be allocated immediately for any incoming uMTC burst data. Resource allocation of the mtc slice 210 may occur within the eMBB or mtc TTI, e.g., 1, 3, 5, 7, 9 slots of the mtc slice 210 occur in the middle of the eMBB TTI. Thus, sufficient air interface resources need to be reserved for the mtc slice 210, otherwise, burst data thereof cannot obtain resources in time for transmission. However, the data arrival time and burst length are unpredictable, so in some cases the resources reserved for short TTIs may be wasted, as explained in more detail below in connection with fig. 3.

Fig. 3 shows a schematic diagram of resource waste in a short TTI slice according to an embodiment of the present disclosure. As shown in fig. 3, 310 may correspond to a short TTI slice, e.g., a uMTC slice for data transmission of the uMTC UE 121 with a TTI of 0.25ms in fig. 1, similar to 210 in fig. 2. 320 may correspond to a long TTI slice, e.g., an eMBB slice for data transmission by an eMBB UE 122 with a TTI of 0.5ms in fig. 1, similar to 220 in fig. 2. 330 indicates the time slots in the resources reserved for short TTI slices that are free due to no data padding. In general, the resource allocation method for a slice cannot reuse idle resources reserved for other slices, and thus there is a problem of resource waste and a problem of low frequency resource utilization.

Therefore, the main idea of the embodiments of the present disclosure is to reuse idle resources among the resources reserved for short TTI slices for transmitting long TTI slices. Thereby waste of resources reserved for short TTI slices can be avoided and thus resource utilization is improved. According to the embodiment of the disclosure, idle resource blocks in a short TTI slot can be utilized to construct resource blocks of a long TTI, so that the auxiliary transmission of the long TTI slice through the short TTI slice is realized. This is explained in more detail below in conjunction with fig. 4.

Fig. 4 shows a schematic diagram of the basic principles of secondary transmission via short TTI slice resources to long TTI slices according to an embodiment of the present disclosure. According to embodiments of the present disclosure, idle resource blocks in a short TTI slot (e.g., Δ f × 0.25ms resource blocks shown in fig. 4) may be used to construct resource blocks of a long TTI (e.g., Δ f × 0.5ms or Δ f × 1ms shown in fig. 4). The basic principle is to convert the frequency domain spreading (short TTI resource blocks) into the time domain spreading (long TTI resource blocks). As shown in fig. 4, 410 may correspond to the mtc slice 210 of fig. 2, and 401, 402 indicate free resource blocks in 410, respectively. 420 may correspond to the eMBB slice 220 of fig. 2, and 403 indicates free resource blocks in 420. 430 may correspond to mtc slice 230 of fig. 2. As shown at 404, a 0.5ms resource block 405 for eMBB slice transmission may be constructed from the free resource blocks of the uftc slice indicated at 401 by a frequency-to-time domain conversion. As shown at 406, a 1ms resource block 407 suitable for an eMBB slice or an mtc slice may be constructed from the free resource blocks of the uftc slice indicated at 402 by frequency-to-time domain conversion. As shown at 408, a 1ms resource block 409 for an mtc slice may be constructed from the free resource blocks of the eMBB slice indicated at 403 by a frequency-to-time domain conversion. Fig. 4 is an example only and is not intended to limit the case of idle resource blocks in any way.

Based on this, the embodiments of the present disclosure provide a scheme for transmitting data that can be implemented on the network device (e.g., eNB 110 of fig. 1) side and a scheme for receiving data that can be implemented on the terminal device (e.g.,

UE

121 and 123 of fig. 2) side. This is explained in more detail below in conjunction with fig. 5-11.

Fig. 5 shows a flow diagram of a method 500 implemented at a network device for transmitting data in accordance with an embodiment of the disclosure. The method may be implemented, for example, on the eNB 110 side of fig. 1. As shown in fig. 5, a first data stream is transmitted using a first slice of network resources, both the first data stream and the first slice of network resources being associated with a first time slot, at 510. At 520, a second data stream is transmitted utilizing a second slice of network resources, the second data stream and the second slice of network resources both being associated with a second time slot, the TTI of the second time slot being greater than the TTI of the first time slot.

In embodiments of the present disclosure, the first network resource slice may correspond to a short TTI slice (e.g., 210 of fig. 2) and the second network resource slice corresponds to a long TTI slice (e.g., 220 or 230 of fig. 2). In an embodiment of the present disclosure, for example, eNB 110 may allocate a mtc slice 210 (a first network resource slice) for mtc data (a first data stream) to be sent to mtc UE 121 and send the mtc data using the slice 210. Meanwhile, an eMBB slice 220 (second network resource slice) may be allocated for eMBB data (second data flow) to be transmitted to the eMBB UE 122 and the eMBB data may be transmitted with the slice 220.

At 530, it is determined whether the size of free resource blocks on the first network resource slice exceeds a value of the TTI length of the second slot. According to embodiments of the present disclosure, the size of the idle resource blocks may be the TTI length of the slot x the number of idle resource blocks. For example, following the above example, the TTI length of the first slot may be 0.25ms and the TTI length of the second slot may be 0.5 ms. In response to determining at 530 that the size of the idle resource blocks is less than the value of the TTI length of the second slot, eNB 110 may return to 510 and 520 to continue operation. In response to determining at 530 that the size of the idle resource blocks is greater than or equal to the value of the TTI length of the second slot, proceed to 540.

At 540, at least a portion of the second data stream is transmitted utilizing at least a portion of the resources in the idle resource blocks. In embodiments of the present disclosure, to use idle resources of a short TTI slice, data of a long TTI slice may be allocated to idle resources of a short TTI slice in each short TTI scheduling. For example, when an idle resource occurs in the mtc slice 210, if the idle resource is two resource blocks (0.25ms × 2) as shown in 410 of fig. 4, the idle resource may be allocated to the eMBB slice 220 for assisting in transmitting eMBB data.

According to an embodiment of the present disclosure, first control information related to resource allocation of a first data stream is transmitted using a first network resource slice, and second control information related to resource allocation of a second data stream is transmitted using a second network resource slice. That is, although at least a portion of the second data stream is transmitted using free resources in the first network resource slice, the indication information of the resource allocation of the at least a portion of the second data stream (i.e., the second control information) is still transmitted using the control channel of the second network resource slice. In an embodiment of the present disclosure, the transmitting the second control information includes: transmitting first assistance information using a next time slot in a second slice of network resources, the first assistance information indicating that at least a portion of a second data stream is transmitted using the first slice of network resources.

In the embodiments of the present disclosure, it is assumed that the indication information of the resource allocation is transmitted in the header (control channel) of each TTI slot. According to the embodiment of the disclosure, when an idle resource occurs on the mtc slice 210, a part of the eMBB data to be transmitted may be mapped to the idle resource for transmission. This time may be during the TTI of the eMBB slice. Accordingly, the assistance information (first assistance information) of the auxiliary resource allocation will be conveyed to the eMBB UE 122 on the control signaling of the next scheduling period of the eMBB slice 220 (in the header of the next 0.5ms slot) for reception of the second data stream. This mechanism may be referred to as a transmit-before-indication. This is explained in detail below with reference to fig. 6.

Fig. 6 shows a schematic diagram of a resource allocation and indication mechanism according to an embodiment of the present disclosure. As shown in fig. 6, 610 is a short TTI slice, e.g., may correspond to the mtc slice 210 of fig. 2, and 601, 602 each indicate a free resource block in 610. 620 is a long TTI slice, which may correspond to, for example, the eMBB slice 220 of fig. 2. In an embodiment of the present disclosure, the idle resource blocks of 601 and 602 are respectively allocated to the long TTI slice 620 for transmitting the corresponding eMBB data. Since the auxiliary information indicating auxiliary transmission of the short TTI slice cannot be included in the header 603 of the current slot, which is during the TTI of the current slot of the long TTI slice 620 at this time, the auxiliary information will be included in the header 604 of the next slot in the long TTI slice 620 to facilitate reception of the eMBB data.

In embodiments of the present disclosure, when a long TTI slice (e.g., 620) uses resources of a short TTI slice (e.g., 610), the allocation indication is still included in the control channel of the long TTI slice.

For example, at each 0.25ms slot, the slice 210 is first allocated resources. If the 0.25ms slot resource is fully occupied by the slice 210's data, then the current 0.25ms slot will serve only the slice 210. If the 0.25ms slot resource is free or partially occupied by data for slice 210, then resources are allocated for slice 220. At this point, the current 0.25ms slot will serve both slice 210 and slice 220. Although the 0.25ms TTI slot conveys data for the partial slice 220, the first assistance information, as described above, is still transmitted in the 0.5ms TTI slot. Since the 0.25ms data allocation is earlier than the 0.5ms control channel (assuming it is located in the header of the slot), the side information in the 0.5ms slot will indicate a duration of two 0.25ms slots.

According to an embodiment of the present disclosure, the first assistance information may include at least one of the following information: an identification of a network resource slice used to transmit at least a portion of the second data stream, a location of the at least a portion of the resources in the network resource slice, a size of the at least a portion of the resources, a TTI length of a slot associated with the network resource slice, an arrangement of the data in the at least a portion of the resources. For example, the first assistance information may include, for example, a time-frequency spatial location, a size, a TTI length, and a data arrangement of resource blocks used to transmit long TTI slices in short TTI slots (e.g., 0.25ms slots), and so on.

Embodiments of the present disclosure have been described above in connection with a situation where there are two different TTI transmissions in one frame structure. However, the disclosed embodiments may also be applicable to situations where there are more kinds of TTI transmissions in one frame structure. As a further example, an embodiment in a case where there is a third network resource slice for a third slot transmission in addition to the first network resource slice and the second network resource slice described above is described below.

In embodiments of the present disclosure, similar to 510 and 520 of fig. 5, eNB 110 may also transmit a third data stream using a third slice of network resources, both the third data stream and the third slice of network resources being associated with a third time slot, a TTI of the third time slot being greater than a TTI of the second time slot. For example, the third network resource slice may correspond to mtc slice 230 of fig. 2, the third data flow may correspond to mtc data flow, and the TTI of the third slot may be 1 ms. In this case, similar to the processes of 530 and 540 of fig. 5, the eNB 110 may transmit at least a portion of the third data stream by utilizing at least a portion of resources in the idle resource blocks in response to a size of the idle resource blocks present on at least one of the first network resource slice and the second network resource slice exceeding a value of a TTI length of the third slot. Similarly, in an embodiment of the present disclosure, eNB 110 may also transmit third control information related to resource allocation of a third data stream using a third network resource slice. For example, the eNB 110 may transmit second assistance information by utilizing a next time slot in a third network resource slice, the second assistance information indicating that at least a portion of a third data stream is transmitted utilizing at least one of the first network resource slice and the second network resource slice. As described in more detail below in conjunction with fig. 7.

Fig. 7 shows a schematic diagram of a resource allocation and indication mechanism according to another embodiment of the present disclosure. As shown in fig. 7, 710 may correspond to the mtc slice 210 of fig. 2, 720 may correspond to the eMBB slice 220 of fig. 2, and 730 may correspond to the mtc slice 230 of fig. 2, for example. In an embodiment of the present disclosure, when it is determined that there is a free resource block 701 in the slice 720 during TTI (1ms) of the slice 730 and the size of the free resource block 701 is 0.25ms × 4 ═ 1ms, the free resource block 701 is allocated for transmission of mtc data, and auxiliary information (second auxiliary information) indicating the resource block 701 is transmitted in the header 702 of the next slot of the slice 730. When it is determined that there is a free resource block 703 in the slice 710 and the size of the free resource block 703 is 0.25ms × 4 to 1ms and that there is a free resource block 704 in the slice 720 and the size of the free resource block 704 is 0.25ms × 4 to 1ms during the next TTI (1ms) of the slice 730, both the free resource blocks 703 and 704 are allocated for transmitting mtc data. Further, side information (second side information) indicating the resource blocks 703 and 704 is transmitted in the header 705 of the next slot of the slice 730.

According to an embodiment of the present disclosure, the second assistance information may include at least one of the following information: an identification of a network resource slice used to transmit at least a portion of the third data stream, a location of the at least a portion of the resources in the network resource slice, a size of the at least a portion of the resources, a TTI length of a slot associated with the network resource slice, an arrangement of the data in the at least a portion of the resources. For example, the second assistance information may include a time-frequency spatial location, a size, a TTI length, and a data arrangement of resource blocks used to transmit a long TTI slice (e.g., slice 730) in a short TTI slice (e.g., slice 710 or 720), and so on. For example, the auxiliary information at 703 may include a time-frequency domain position of the resource block 701 in the slice 720, a size of the resource block 701, a TTI length of the slice 720, an arrangement of data in the resource block 701 (such as the arrangements shown in fig. 7 as 1, 2, 3, and 4), and the like.

Thus far, a method for transmitting data implemented on the network device side has been described. By the method, idle resources in the short TTI slice can be reused to transmit the long TTI slice, so that resource waste is avoided and the resource utilization rate is improved. Correspondingly, the embodiment of the disclosure also provides a method for receiving data, which is implemented on the terminal equipment side. Fig. 8 shows a flow diagram of a method 800 implemented at a terminal device for receiving data in accordance with an embodiment of the disclosure. The method may be implemented at a long TTI UE, such as the eMBB UE 122 or mtc UE 123 shown in fig. 1.

As shown in fig. 8, at 810, a first signal stream comprising at least a first data stream is received from a first network resource slice, the first data stream and the first network resource slice both being associated with a first time slot. At 820, a second signal stream comprising at least a second data stream is received from a second slice of network resources, the second data stream and the second slice of network resources both being associated with a second time slot, a TTI of the second time slot being greater than a TTI of the first time slot.

As mentioned above, in embodiments of the present disclosure, the first network resource slice may correspond to a short TTI slice, such as the mtc slice 210 or the eMBB slice 220 of fig. 2. The second network resource slice may correspond to a long TTI slice, such as the eMBB slice 220 or the mtc slice 230 of fig. 2. According to embodiments of the present disclosure, the eMBB UE 122 needs to receive not only the second signal stream from the eMBB slice 220 (second network resource slice) but also the first signal stream from the mtc slice 210 (first network resource slice). According to an embodiment of the present disclosure, only the first signal stream during one long TTI may be stored. For example, the eMBB UE 122 may receive and buffer the first signal stream during its current TTI (0.5ms, corresponding to two 0.25ms slots). Therefore, this does not substantially cause an increase in the buffering cost of the UE.

At 830, it is determined whether at least a portion of the second data stream is present in the first signal stream. In an embodiment of the present disclosure, the first signal stream may include first control information related to resource allocation of the first data stream, and the second signal stream may include second control information related to resource allocation of the second data stream. For example, the control information may be included in a header of each corresponding slot. According to an embodiment of the present disclosure, it may be determined whether at least a portion of a second data stream is present in a first signal stream by determining whether second control information in a next slot of a second network resource slice includes first assistance information indicating that the at least a portion of the second data stream is transmitted using the first network resource slice. The description of the first auxiliary information is similar to that described above in connection with fig. 6 and will not be repeated here.

For example, when the eMBB UE 122 decodes a control channel from a 0.5ms slot, finding that no assistance information (first assistance information) is present, it may be determined that no portion of the second data stream is present in the first signal stream. In response to determining that no portion of the second data stream is present in the first signal stream, returns 810 and 820 to continue receiving the first and second signal streams. The presence of the assistance information (first assistance information) is found, for example, when the eMBB UE 122 decodes a control channel from a 0.5ms slot, it may be determined that at least a portion of the second data stream is present in the first signal stream. In response to determining that at least a portion of the second data stream is present in the first signal stream, 840 is entered.

At 840, a second data stream is obtained from the first signal stream and the second signal stream. According to an embodiment of the present disclosure, an auxiliary signal stream related to at least a portion of the second data stream is constructed from the first signal stream based on the first auxiliary information, and the second data stream is decoded from the second signal stream and the auxiliary signal stream based on the second control information. For example, the eMBB UE 122 may extract resource blocks (e.g., 401 of fig. 4) related to at least a portion of the second data stream from the first signal stream buffered at 810 based on the auxiliary information in the control channel of the next slot, the resource blocks being arranged on the frequency axis, and then rearrange the resource blocks on the time axis to construct an auxiliary signal stream (e.g., 405 of fig. 4) corresponding to 0.5ms resource blocks. The eMBB UE 122 may then decode a second data stream from the currently received second signal stream and the constructed auxiliary signal stream based on second control information in the control channel of the current time slot. The decoding process herein may be performed in any manner known in the art or developed in the future and will not be described in detail herein in order to avoid obscuring the concepts of the present invention.

According to an embodiment of the present disclosure, the method 800 may further include (not shown in the figures): a third signal stream comprising at least a third data stream is received from a third slice of network resources, the third data stream and the third slice of network resources both being associated with a third time slot, a TTI of the third time slot being greater than a TTI of the second time slot. For example, the third network resource slice may correspond to mtc slice 230 of fig. 2, the third data flow may correspond to mtc data flow, and the TTI of the third slot may be 1 ms. According to an embodiment of the present disclosure, the third signal stream comprises third control information related to resource allocation of the third data stream. For example, similarly, corresponding control information (third control information) may be included in the header of each slot of the mtc slice.

According to an embodiment of the present disclosure, the method 800 may further include (not shown in the figures): it is determined whether at least a portion of the third data stream is present in the first signal stream or the second signal stream. The processing of this step is similar to the processing of step 830 and will not be described again here. According to an embodiment of the present disclosure, the method 800 may further include (not shown in the figures): in response to at least one of the first signal stream and the second signal stream comprising at least a portion of a third data stream, the third data stream is obtained from the third signal stream and at least one of the first signal stream and the second signal stream. The processing of this step is similar to that of step 840 and will not be described here.
