Description

Data scheduling method and device

Technical Field

The present disclosure relates to the field of communications, and in particular, to a data scheduling method and apparatus.

Background

A new generation mobile communication system nr (new radio) is being researched and standardized, which is also one of the major points of the current 3 GPP.

In the NR system that can be determined in the related art, there are 3 typical traffic types in the future. Common services include: enhanced Mobile BroadBand (eMBB), Ultra-high-Reliable and Low Latency Communications (URLLC), and massive Machine Type Communications (mMTC). These services have different requirements with respect to delay, coverage and reliability. For example, for the eMBB, high peak transmission rate is mainly emphasized, the requirement on delay is not high (low delay is not required), and the reliability is required. For URLLC, low-delay, high-reliability transmission is emphasized, and the delay requirement is very strict. For mtc, a large number of medium terminals are emphasized, the connection density is high and more transmission coverage is required, and there is little requirement for latency.

In the related art, in the standard discussion of NR, in principle, a short uplink control channel (short PUCCH) and a long uplink control channel (long PUCCH) are allowed to be frequency division multiplexed in a slot in a short PUCCH region, but in the related art, the control channel can only transmit control signaling, the data channel can only transmit data (uplink data or downlink data), and the control channel cannot transmit data.

Aiming at the problem of low resource utilization efficiency of an uplink control channel in the related art, no effective solution is found at present.

As used below, the term "module" may be a combination of software and/or hardware that implements a predetermined function. Although the means described in the embodiments below are preferably implemented in software, an implementation in hardware, or a combination of software and hardware is also possible and contemplated.

The present embodiment also provides a data scheduling system, including the above base station and the above terminal, where the base station includes: a sending module, configured to send uplink grant information in a scheduling unit a, where uplink data corresponding to the uplink grant information is scheduled to be sent in at least one scheduling unit B; a receiving module, configured to receive, in a short uplink control region of the scheduling unit B, uplink data corresponding to the uplink grant information; the terminal comprises; a receiving module, configured to receive, in a scheduling unit a, uplink grant information sent by a base station, where uplink data corresponding to the uplink grant information is scheduled to be sent in at least one scheduling unit B; and a sending module, configured to send, in the short uplink control region of the scheduling unit B, uplink data corresponding to the uplink grant information.

It should be noted that, the above modules may be implemented by software or hardware, and for the latter, the following may be implemented, but not limited to: the modules are all positioned in the same processor; alternatively, the modules are respectively located in different processors in any combination.

Example 3

The present embodiment provides a method for scheduling data, which can transmit data by using resources of an uplink control channel, thereby improving resource utilization efficiency when there are idle resources in the uplink control channel. When uplink data corresponding to the uplink grant information is required to be transmitted in a slot B (corresponding to scheduling unit B), it is default that the uplink data is transmitted in the short PUCCH region of the slot B if the slot B satisfies the following condition. With the following conditions: the slot b contains the downlink slot.

Uplink control channels in the NR system are divided into a short uplink control channel (short PUCCH) and a long uplink control channel (long PUCCH), which are respectively used for different purposes. For example, the short PUCCH is generally located at the last few OFDM symbols of the slot (for example, 1 or 2 OFDM symbols), and companies also propose to place the short PUCCH at the slot (which may be understood as a scheduling unit, and the slot is just a term) and a few symbols before uplink data. E.g., the last few symbols of a downlink slot, or the last few symbols of an uplink slot. The method is mainly used for timely ACK/NACK feedback and sending other channel state information CSI, and is mainly used for UE which is a cell center accessory. For example, the long PUCCH occupies more OFDM symbols, mainly for the UE at the cell edge, and after more symbols are used, it is beneficial to improve the coverage of the long PUCCH, so the long PUCCH is introduced mainly for the coverage of a wider range.

Related art in the standard discussion of NR, it is principally supported to allow frequency division multiplexing of a short PUCCH and an uplink data channel (PUSCH) in one slot in a short PUCCH region, but details are not given on how to frequency division multiplex. Further, one short PUCCH occupies 1 or 2 OFDM symbols. The current short PUCCH is located at the end of the slot, and it is also proposed that the short PUCCH should also be located in the uplink slot before the uplink data.

In the related art NR system, the definition of slot is summarized as follows: the Slot comprises a descending part, a GAP (GAP) and an ascending part, and at least one of the 3 parts is included in the Slot. The downlink part comprises downlink control information (comprising downlink authorization information and/or uplink authorization information) and downlink data, and the uplink part comprises uplink data and a long/short uplink control area (information). The typical structure is as follows: the structure of the downlink slot is downlink control information, downlink data, GAP and a short uplink control area; or the structure of the downlink slot is a downlink data and GAP short uplink control area; or the structure of the downlink slot is downlink control information and downlink data; or the structure of the downlink slot is downlink data. A typical upstream slot structure is: the downlink control information, the GAP, the uplink data, the short uplink control region, or the uplink slot structure is the downlink control, the GAP, the uplink data, or the uplink slot structure is the uplink data.

By the embodiment, the PUSCH can be efficiently transmitted in the resources of the PUCCH, and the UE can accurately know the specific resources of the uplink data.

The present embodiment includes a plurality of examples, and each of the following examples may exist independently, and technical features in different examples may be combined and used in combination in one embodiment. The PUSCH resource herein refers to a PRB resource in general, and the PUCCH resource may be a PRB, OFDM symbol, subcarrier, etc., or a combination. The PUCCH not specifically described herein may be a short PUCCH and/or a long PUCCH. The PUSCH and PUCCH herein correspond to a physical uplink data channel (also referred to by transmission characteristics, e.g., uplink data or uplink data region), a physical uplink control channel (also referred to by transmission characteristics, e.g., uplink control region or uplink control), respectively; in the standard formulation of NR, PUSCH and PUCCH may be abbreviated as NR-PUSCH and NR-PUCCH, but they are still physical uplink data channel and physical uplink control channel, and the carrying content is unchanged, so the naming does not affect the implementation of the method herein.

The present embodiment is explained in four ways:

in the method 1, the base station sends uplink grant information (i.e. scheduling information of uplink data) in a downlink slot or an uplink slot, and data corresponding to the uplink grant information is required to be sent in the slot. And the base station receives the uplink data corresponding to the uplink authorization information in the short uplink control region of the slot. (Transmission in the short PUCCH domain implied by the uplink data being transmitted in the downlink slot)

In the method 2, the base station sends uplink grant information (i.e. scheduling information of uplink data) in a downlink slot or an uplink slot, and the uplink data corresponding to the uplink grant information is required to be sent in a certain downlink slot or certain downlink slots. And the base station receives the uplink data corresponding to the uplink authorization information in a short uplink control region of one or some downlink slots. (Transmission of uplink data in the short PUCCH domain is implied by the uplink data being transmitted in the downlink slots for some slots actually being slot aggregation)

In mode 3, the base station sends uplink grant information (i.e. scheduling information of uplink data) in a downlink slot or an uplink slot, and the uplink data corresponding to the uplink grant information is required to be sent in some or some uplink slots. And the base station receives the uplink data corresponding to the uplink authorization information in the short uplink control region of the certain or some downlink slots.

In mode 4, the base station sends uplink grant information (i.e. scheduling information of uplink data) in the downlink or uplink slot, and the uplink data corresponding to the uplink grant information is required to be sent in some or some of the downlink and uplink slots. And the base station receives the uplink data corresponding to the uplink authorization information in the short uplink control region of the certain or some downlink slots. (by means of the fact that the slot corresponding to the uplink data comprises the downlink slot, the uplink data is implicitly transmitted in the short PUCCH domain of all slots

Example 1 (corresponding mode 1)

Fig. 5 is a schematic scheduling diagram corresponding to mode 1 in the embodiment of the present disclosure, and corresponding to fig. 5, uplink data corresponding to uplink grant information is transmitted in a downlink slot (i.e., slot b) to implicitly transmit the uplink data in a short PUCCH region of the slot.

The base station sends uplink grant information (i.e. information for scheduling uplink data) in a slot a (corresponding to the scheduling unit a, which may be a downlink slot or an uplink slot, or a reserved empty slot (such a slot is reserved for not transmitting downlink data or uplink data of the current version system), as long as the slot allows sending the uplink grant information), and the uplink data corresponding to the uplink grant information is required to be sent in the slot (i.e. slot b). And the base station receives uplink data corresponding to the uplink authorization information in a short uplink control region (PUCCH) of the slot.

The short PUCCH may be on the last several symbols in the downlink slot or may be supported on several symbols before the downlink data. In addition, the short PUCCH may also be on the last several symbols of the uplink slot, or may also be supported on several symbols before the uplink data. In the current NR system, a self-contained structure is also supported, that is, a slot may contain a downlink control region, an uplink control region, and uplink/downlink data.

The UE receives the uplink grant information from the slot a, and then can know, according to the timing relationship between the uplink grant information and the corresponding uplink data, which slot the uplink data is to be sent in, and further can know, through notification of the slot structure, the type of the slot to which the uplink data is sent, that is, whether the slot is a downlink slot, an uplink slot, or a reserved slot. And when the slot corresponding to the uplink data is the downlink slot, the UE considers that the uplink data is to be transmitted in the short uplink control region of the downlink slot. The related information in the corresponding uplink grant information is also used in the short uplink control region. And the UE transmits uplink data in the slot short PUCCH domain according to the requirement of the uplink authorization information. Correspondingly, the base station will also receive uplink data in the slot short PUCCH domain according to the requirement of uplink grant information.

Here, there is no extra parameter in the uplink grant information to indicate that the current uplink grant information is for the slot short uplink control domain, but the slot corresponding to the uplink data is the downlink slot to imply that the uplink data corresponding to the uplink grant information needs to be transmitted in the slot short uplink control domain. And thus no overhead.

Example 2 (corresponding mode 2)

Fig. 6 is a schematic scheduling diagram corresponding to mode 2 in the embodiment of the present disclosure, and corresponding to fig. 6, uplink data corresponding to uplink grant information is transmitted in some downlink slots (i.e., slots b) to imply that the uplink data is transmitted in a short PUCCH domain. This is the case for the base station scheduling uplink data to be transmitted using the short PUCCH region in each of the plurality of downlink slots. These downlink slots can be considered as a way of slot aggregation.

The base station sends the uplink authorization information (i.e. information for scheduling the uplink data) in slot a (which may be a downlink slot or an uplink slot, or a reserved empty slot (such a slot is reserved and does not transmit downlink data or uplink data of a current version system), as long as the slot allows sending the uplink authorization information), and the uplink data corresponding to the uplink authorization information is required to be sent in multiple downlink slots (i.e. slots b). And the base station receives the uplink data corresponding to the uplink authorization information in the short uplink control regions (PUCCHs) of the slots. The uplink data scheduled by the uplink grant information is required to be transmitted in a plurality of downlink slots, and can also be regarded as uplink data transmission under slot aggregation, and the aggregated slots may be continuous or discrete.

The UE receives the uplink grant information from the slot a, determines that a slot for transmitting uplink data corresponding to the uplink grant information is a slot b (the slot b includes multiple slots, which are sometimes described directly below), and then determines a timing relationship between the uplink grant information and the corresponding uplink data, so as to know that the uplink data will be transmitted in those slots. Further, through the notification of the slot structure, the UE may know the type of the slot sent by the uplink data, that is, whether the slot is a downlink slot, an uplink slot, or a reserved slot, and in this example, it is assumed that the UE knows that the multiple slots are all downlink slots. When the slots corresponding to the uplink data are downlink slots, the UE considers that the uplink data will be transmitted in the short uplink control region of the downlink slots. The relevant information in the corresponding uplink grant information is also for the short uplink control region of these slots. And the UE transmits uplink data in the short PUCCH domains of the slots according to the requirement of the uplink authorization information. Correspondingly, the base station will also receive uplink data in these slot short PUCCH domains according to the requirement of uplink grant information.

Here, there is no extra parameter in the uplink authorization information to indicate that the current uplink authorization information is for the slot short uplink control domain, but it is implied that the uplink data corresponding to the uplink authorization information needs to be transmitted in the slot short uplink control domain by using that the slots corresponding to the uplink data are all downlink slots. And thus no overhead.

Example 3 (corresponding mode 3)

Fig. 7 is a first scheduling schematic corresponding to the method 3 in the embodiment of the present disclosure, and fig. 8 is a second scheduling schematic corresponding to the method 3 in the embodiment of the present disclosure, in the method 3, the base station sends uplink grant information (i.e., scheduling information of uplink data) in a downlink or uplink slot, and the uplink data corresponding to the uplink grant information is required to be sent in a certain or some uplink slots. And the base station receives the uplink data corresponding to the uplink authorization information in the short uplink control region of the certain or some uplink slots.

Introducing additional indication information into the uplink authorization information, or appointing a fixed uplink authorization information format to be used for uplink data scheduling in a short uplink control region in a slot. Obviously, this method is also applicable to uplink data scheduling in the methods 1, 2, and 4, and at this time, it may no longer use the downlink slot included in the scheduled slot b to imply that this scheduling is for the short uplink control region in the slot.

In this embodiment, a new uplink grant is designed, where a new parameter is introduced into the uplink grant to describe that uplink data corresponding to the uplink grant is scheduled in the short uplink control region in the slot, and the uplink grant is used to schedule uplink data transmission for transmission in the short uplink control region in the slot. Or the base station and the UE agree on a fixed uplink grant information format, which is used for scheduling uplink data transmission in the short uplink control region in the slot.

The base station sends uplink authorization information (namely information for scheduling uplink data) in a slot A (which may be a downlink slot or an uplink slot or a reserved empty slot (the slot is reserved not to transmit downlink data or uplink data of a current version system), as long as the slot is allowed to send the uplink authorization information), the uplink authorization information includes a new parameter for indicating that the current uplink authorization information is for performing uplink data scheduling for a short uplink control region in the slot, or the uplink authorization information adopts an agreed format, the format is agreed for performing uplink data scheduling for the short uplink control region in the slot, and the uplink data corresponding to the uplink authorization information is required to be in a slot B (the slot B includes one or more slots, and when the slots are all uplink slots or downlink slots, or both uplink slots and downlink slots), it may be a downlink slot or an uplink slot. Sometimes directly described below) in multiple slots. And the base station receives uplink data corresponding to the uplink authorization information in the short uplink control region of the slotB.

The short PUCCH may be on the last few symbols in the downlink slot or may be supported on a few symbols before the downlink data. In addition, the short PUCCH may also be on the last several symbols of the uplink slot, or may also be supported on several symbols before the uplink data. In the current NR system, a self-contained structure is also supported, that is, a slot may contain a downlink control region and an uplink control region and uplink/downlink data.

The UE receives the uplink grant information from the slot a, and then directly knows that the corresponding uplink data transmission is in the slot short uplink control region according to the uplink grant information. For example, the new parameters introduced in the uplink grant information may be directly analyzed, or the new parameters may be obtained by scheduling the uplink data in the short uplink control region in the slot according to the format of the uplink grant information.

The UE can know that the uplink data will be sent in the slots according to the timing relationship between the uplink grant information and the corresponding uplink data, and the UE sends the uplink data in the corresponding short uplink control region according to the requirement of the uplink grant information when the slots arrive. Correspondingly, the base station will also receive uplink data in these slot short uplink control regions according to the requirement of uplink grant information.

Mode 3 can be used as if slot b is a pure upstream slot, while modes 1, 2, 4 are not. In this case, mode 3 may implement multiple uplink slot aggregation. The slots that are aggregated may be continuous or discrete. Mode 3 introduces overhead or appoints the format of uplink grant (equivalent to increase the number of formats for UE blind detection) to schedule uplink data for the short uplink control region, and thus has high flexibility. But overhead and complexity are also increased.

Example 4 (corresponding mode 4)

Fig. 9 is a schematic scheduling diagram corresponding to the method 4 in the embodiment of the present disclosure, and corresponding to fig. 9, uplink data corresponding to the uplink grant information is transmitted in a slot (i.e., slot b) to implicitly transmit the uplink data in the short PUCCH area. The slot here requires to include at least one downlink slot, and obviously, when a plurality of slots exist at that time, as long as at least one downlink slot is included, other slots may be uplink slots. This is the case for the base station scheduling uplink data to be transmitted using the short PUCCH region in each of the slots. These slots can be considered as a way of slot aggregation, except that the aggregation in this embodiment allows these slot attributes to be aggregated together for both upstream and downstream slots.

The base station sends the uplink authorization information (i.e. information for scheduling the uplink data) in a slot a (which may be a downlink slot or an uplink slot, or a reserved empty slot (such a slot is reserved for not transmitting the downlink data or the uplink data of the current version system), as long as the slot allows sending the uplink authorization information), and the uplink data corresponding to the uplink authorization information is required to be sent in a slot b (the slot b includes multiple slots, and at least one of the multiple slots is a downlink slot, sometimes directly described below). And the base station receives the uplink data corresponding to the uplink authorization information in the short uplink control regions (PUCCHs) of the slots. The uplink data scheduled by the uplink grant information is required to be transmitted in a slot b (the slot b includes a plurality of slots), and such transmission can also be regarded as uplink data transmission under a hybrid aggregation of uplink slots and downlink slots. The slots that are aggregated may be continuous or discrete.

The UE receives the uplink grant information from the slot a, then knows that the uplink data will be sent in the slots according to the slot that the slot for transmitting the uplink data corresponding to the uplink grant information is a slot b (the slot b includes multiple slots, and sometimes, the multiple slots are described directly below), and further knows the type of the slot for sending the uplink data, that is, the downlink slot or the uplink slot or the reserved slot, according to the notification of the slot structure, in this example, the UE knows that there are downlink slots and uplink slots in the multiple slots. When there is a downlink slot (at least one downlink slot) in the slots corresponding to the transmitted uplink data, the UE considers that the uplink data is to be transmitted in the short uplink control regions of the slots. The relevant information in the corresponding uplink grant information is also for these slot short uplink control regions. And the UE transmits uplink data in the short PUCCH domains of the slots according to the requirement of the uplink authorization information. Correspondingly, the base station will also receive uplink data in these slot short PUCCH domains according to the requirement of uplink grant information.

Here, there is no extra parameter in the uplink grant information to indicate that the uplink grant information is for the slot short uplink control domain, but it is implied that the uplink data corresponding to the uplink grant information needs to be transmitted in the slot short uplink control domain by having a downlink slot in the slot corresponding to the uplink data. Thus, there is no overhead.

In the present application, technical features in various embodiments and examples may be combined and used in one embodiment without conflict. Each example is merely the best mode of carrying out the present application.

By the solution provided by this embodiment, the uplink data corresponding to one uplink grant information can be implicitly sent to the short uplink control area, so that uplink data scheduling in the uplink control area is realized on the basis of no overhead, and thus, when the uplink control area is idle, more uplink data can be transmitted, thereby improving efficiency.
