Description

Method, device, communication equipment and storage medium for jointly scheduling multiple transmission blocks

Technical Field

The present disclosure relates to the field of wireless communications technologies, but not limited to the field of wireless communications technologies, and in particular, to a method, an apparatus, a communication device, and a storage medium for jointly scheduling multiple transport blocks.

Background

In fifth generation mobile communication technology (5G) networks, a new device type, i.e. reduced capability user equipment (Redcap UE) was introduced. Reduced capability user equipment (Redcap UE) typically needs to meet the following requirements: 1. low cost and complexity; 2. coverage enhancement; 3. power is saved. Since the New air interface (NR) is designed for high-end terminals with high speed, low delay, and the like, the New Radio interface cannot meet the above requirements. Therefore, new air interface (NR) systems need to be modified to meet the above requirements.

In the related art, for uplink and Downlink Transmission, a base station schedules physical resources, modulation and coding formats, and the like required for a Transport Block (TB) through Downlink Control Information (DCI) signaling. Since the terminal cannot know the specific bearer location of the Downlink Control Information (DCI), the terminal needs to perform blind detection on a search space when receiving the Downlink Control Information (DCI). Therefore, the blind test complexity of the terminal is high, multiple blind tests are required, the power consumption of the terminal is increased by excessive blind test times, and the requirement of power saving cannot be met.

Here, the user equipment described above may be regarded as the terminal equipment of the following embodiments.

In some embodiments, the wireless communication system may further include a network management device 130.

Several base stations 120 are connected to the network management device 130, respectively. The network Management device 130 may be a Core network device in a wireless communication system, for example, the network Management device 130 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the Network management device may also be other core Network devices, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), a Home Subscriber Server (HSS), or the like. The implementation form of the network management device 130 is not limited in the embodiment of the present disclosure.

To facilitate an understanding of any embodiment of the present disclosure, a wireless communication scenario is first described.

In a wireless communication system, in order to support a business of Internet of Things, two wireless communication technologies, Machine-Type communication (MTC) and narrowband Internet of Things (NB-IoT), are proposed. The two wireless communication technologies are mainly aimed at low-rate and high-delay scenarios. Such as meter reading in the internet of things service, environment monitoring and other wireless communication scenarios. In the related art, a narrowband internet of things (NB-IoT) can support a rate of only several hundred k at maximum, and Machine Type Communication (MTC) can support a rate of only several M at maximum. However, with the continuous development of the internet of things service, services such as video monitoring, smart home, wearable devices, and industrial sensing monitoring are increasingly popularized. These services typically require a rate of tens to 100M, with relatively high requirements on latency. However, Machine Type Communication (MTC) and narrowband internet of things (NB-IoT) technologies are difficult to meet. Based on the situation, it is proposed to design a new user equipment in a new air interface of a fifth generation mobile communication technology (5G), wherein the user equipment is used for meeting the requirements of the middle-end internet of things equipment. In the third generation partnership project (3GPP) standardization, this new terminal type is called reduced capability user equipment (Redcap UE).

Similar to the internet of things (lot) equipment in a long term evolution wireless communication system, reduced capability user equipment (Redcap UE) generally needs to satisfy the following requirements: 1. low cost and complexity; 2. coverage enhancement; 3. power is saved. Since the new air interface (NR) is designed for high-end terminals with high speed, low delay, and the like, the above requirements cannot be satisfied. There is therefore a need for new air interface (NR) systems that can be adapted to meet the above requirements. For example, to meet the requirements of low cost and low complexity, the radio frequency bandwidth of the reduced capability user equipment (Redcap UE) may be limited; such as to 5 mhz or 10 mhz, or to limit the size of the buffer of a reduced capability user equipment (Redcap UE), and thus the size of each received Transport Block (TB), etc. For power saving, the possible optimization direction is to simplify the communication flow, reduce the number of times that the reduced capability user equipment (Redcap UE) detects the downlink control channel, and the like.

In one embodiment, for uplink and downlink transmission, the base station schedules physical resources, modulation and coding formats, and the like, required for a Transport Block (TB) through Downlink Control Information (DCI) signaling. The base station may perform the simultaneous slot scheduling, specifically refer to fig. 2. The base station may also perform cross-slot scheduling, see fig. 3 for details. In one embodiment, the transmission of the Downlink Control Information (DCI) has a plurality of Physical Downlink Control Channel (PDCCH) candidate locations, which are located in the search space and configured by the base station to the base station through high-level Radio Resource Control (RRC) signaling. Since the terminal does not know the specific bearer location of the Downlink Control Information (DCI), the terminal needs to perform blind detection on the dedicated search space when receiving the Downlink Control Information (DCI). The method greatly increases the scheduling flexibility of the base station and simultaneously reduces the blocking probability of a Physical Downlink Control Channel (PDCCH). Wherein, the simultaneous slot transmission may be that a slot for transmitting the Transport Block (TB) and a slot for transmitting Downlink Control Information (DCI) of the Transport Block (TB) belong to the same slot. The cross-slot transmission may be at least one slot spaced between a slot in which the Transport Block (TB) is transmitted and a slot in which Downlink Control Information (DCI) of the Transport Block (TB) is transmitted.

As shown in fig. 4, the present embodiment provides a method for jointly scheduling multiple transport blocks, which is applied in a base station, where the method includes:

and step 41, sending down the Downlink Control Information (DCI) of a plurality of Transport Blocks (TB).

Wherein, the Downlink Control Information (DCI) comprises: common Downlink Control Information (DCI) and a plurality of dedicated Downlink Control Information (DCI) in one-to-one correspondence with the plurality of Transport Blocks (TBs); common Downlink Control Information (DCI) carrying indication information of a time-frequency domain position of transmission dedicated Downlink Control Information (DCI); common Downlink Control Information (DCI) for carrying common scheduling information for a plurality of Transport Blocks (TBs); dedicated Downlink Control Information (DCI) for carrying scheduling information of a corresponding Transport Block (TB).

In one embodiment, Downlink Control Information (DCI) receiving a plurality of Transport Blocks (TBs) may be a terminal. The terminal may be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a Road Side Unit (RSU), a smart home terminal, an industrial sensing device, and/or a medical device. Here, the terminal may be a reduced capability user equipment (Redcap UE).

The base station is an interface device for the terminal to access the network. The base stations can be of various types, such as base stations of a third generation mobile communication (3G) network, base stations of a fourth generation mobile communication (4G) network, base stations of a fifth generation mobile communication (5G) network, or other evolved base stations.

In one embodiment, Downlink Control Information (DCI) may be information indicating that a terminal performs transmission scheduling. Transmission schedules include, but are not limited to: downlink transmission scheduling and/or downlink transmission scheduling.

For example, Downlink Control Information (DCI) is information for performing data scheduling on a Physical Downlink Shared Channel (PDSCH). For example, Downlink Control Information (DCI) is information for performing data scheduling on a Physical Uplink Shared Channel (PUSCH).

The foregoing uplink transmission scheduling may be referred to as uplink scheduling for short; the aforementioned downlink transmission scheduling may be simply referred to as downlink scheduling.

In one embodiment, whether the Downlink Control Information (DCI) is downlink scheduling information or uplink scheduling information may be indicated by a format indication distinguishing between uplink scheduling and downlink scheduling. For example, when the bit value of the field corresponding to the format indication for distinguishing the uplink scheduling from the downlink scheduling is "0", the Downlink Control Information (DCI) is information indicating that the terminal performs the uplink scheduling. When the bit value of the field corresponding to the format indication for distinguishing the uplink scheduling from the downlink scheduling is "1", Downlink Control Information (DCI) is information indicating that the terminal performs downlink scheduling.

In one embodiment, the common Downlink Control Information (DCI) may be control information for at least one unspecified Transport Block (TB). For example, common Downlink Control Information (DCI) is control information for all Transport Blocks (TBs). The dedicated Downlink Control Information (DCI) may be control information for a specific Transport Block (TB).

In one embodiment, the format indication distinguishing the uplink scheduling from the downlink scheduling may be carried in common Downlink Control Information (DCI).

In one embodiment, the number of the plurality of Transport Blocks (TBs) may be indicated by the number of jointly scheduled Transport Blocks (TBs).

In one embodiment, the number of the jointly Scheduled (TBs) may be carried in common Downlink Control Information (DCI). For example, if the number of jointly scheduled Transport Blocks (TBs) is 4, the number of jointly scheduled Transport Blocks (TBs) is 4.

In one embodiment, the time-frequency domain location may comprise a time domain location where dedicated Downlink Control Information (DCI) is transmitted. The time domain position may comprise the position of the slot and/or the position of the symbol. Here, the position of the symbol may be determined according to the start position of the symbol and the length of the symbol.

In one embodiment, the position of the slot may be indicated by a dedicated Downlink Control Information (DCI) time domain position indication, which may be carried in common Downlink Control Information (DCI). In one embodiment, the position of the symbol in the time domain may be indicated by a dedicated Downlink Control Information (DCI) symbol position indication, which may be carried in common Downlink Control Information (DCI).

In one embodiment, the time-frequency domain location may comprise a frequency domain location where dedicated Downlink Control Information (DCI) is transmitted. The frequency domain position may contain a bandwidth part (BWP) indication. In one embodiment, the bandwidth part (BWP) indication may be carried in common Downlink Control Information (DCI).

In one embodiment, the transmission of multiple Transport Blocks (TBs) may be a simultaneous slot transmission. Referring again to fig. 2, the simultaneous slot transmission may be that a slot in which the Transport Block (TB) is transmitted and a slot in which dedicated Downlink Control Information (DCI) of the Transport Block (TB) is transmitted belong to the same slot.

In one embodiment, the transmission of multiple Transport Blocks (TBs) may be a cross-slot transmission. Referring again to fig. 3, the cross-slot transmission may be at least one slot spaced between a slot in which the Transport Block (TB) is transmitted and a slot in which dedicated Downlink Control Information (DCI) of the Transport Block (TB) is transmitted.

In one embodiment, the common Downlink Control Information (DCI) carries a slot offset indication indicating the number of slots between a slot in which the Transport Block (TB) is transmitted and a slot in which dedicated Downlink Control Information (DCI) for the Transport Block (TB) is transmitted.

In one embodiment, the common Downlink Control Information (DCI) carries a slot position indication of the dedicated Downlink Control Information (DCI). The slot position indication of the special Downlink Control Information (DCI) is used for indicating the slot position relation between different kinds of special Downlink Control Information (DCI) to be transmitted.

In one embodiment, dedicated Downlink Control Information (DCI) carries an indication of the location of the slot in which the Transport Block (TB) is transmitted and the location of the symbol in the time domain.

In one embodiment, the common scheduling information for the plurality of Transport Blocks (TBs) is scheduling information that is needed for transmission of all of the plurality of Transport Blocks (TBs). The scheduling information for a single Transport Block (TB) is the scheduling information that needs to be used for transmitting the corresponding Transport Block (TB).

In one embodiment, please refer to fig. 5, the number of transport blocks to be scheduled is n, which are transport block TB1, transport block TB2, transport block TB3, transport block TB4, …, and transport block TBn, respectively. G1 is common Downlink Control Information (DCI) of transport block TB1 to transport block TBn, Z1 is dedicated Downlink Control Information (DCI) of transport block TB1, Z2 is dedicated Downlink Control Information (DCI) of transport block TB2, and Z3 is dedicated Downlink Control Information (DCI) of transport block TB 3.

In the embodiment of the present disclosure, since the common Downlink Control Information (DCI) carries indication information of a time-frequency domain position where the dedicated Downlink Control Information (DCI) is transmitted, after the terminal receives the common Downlink Control Information (DCI), the terminal can acquire the time-frequency domain position where the dedicated Downlink Control Information (DCI) is transmitted according to the indication information of the common Downlink Control Information (DCI). In this way, when receiving the dedicated Downlink Control Information (DCI), the terminal can receive the dedicated Downlink Control Information (DCI) at the time-frequency domain position indicated by the common Downlink Control Information (DCI) without performing blind detection. Compared with a mode that blind detection needs to be carried out on all Downlink Control Information (DCI) when the Downlink Control Information (DCI) is received, the number of blind detection times when the Downlink Control Information (DCI) is received can be reduced, the complexity of the blind detection is reduced, and the power consumption caused by the blind detection is reduced.

In one embodiment, the common Downlink Control Information (DCI) is issued prior to the dedicated Downlink Control Information (DCI). In this way, the terminal can receive the dedicated Downlink Control Information (DCI) at the time-frequency domain position according to the indication information of the time-frequency domain position carried in the received common Downlink Control Information (DCI).

Here, the format indication for distinguishing the uplink scheduling and the downlink scheduling indicates whether common Downlink Control Information (DCI) is used for uplink scheduling or downlink scheduling. A bandwidth part (BWP) indication indicates the bandwidth used to transmit the transport block. The number of jointly scheduled Transport Blocks (TBs) is used to indicate the number of jointly scheduled transport blocks. A hybrid automatic repeat request (HARQ) starting process number, which is a process number corresponding to a first Transport Block (TB) of N Transport Blocks (TBs) that are jointly scheduled. Wherein, different Transport Blocks (TBs) correspond to different process numbers, and the process number corresponding to the nth TB is: n + starting process number. Wherein N and N are positive integers of 1 or more.

Here, the time domain resource allocation information is used to indicate a starting symbol position and a symbol length within the slot. For example, the starting symbol is the 1 st symbol and the symbol length is 3 symbols.

Here, common Downlink Control Information (DCI) for uplink scheduling is used to schedule a Transport Block (TB) for uplink. Common Downlink Control Information (DCI) for downlink scheduling is used to schedule downlink Transport Blocks (TBs). Here, the number of bits of the common Downlink Control Information (DCI) for uplink and the common Downlink Control Information (DCI) for downlink is made the same by padding "0" in the bits of the common downlink control information, thereby reducing the complexity in performing blind detection on the common Downlink Control Information (DCI).

As shown in fig. 6, the present embodiment provides a method for jointly scheduling multiple transport blocks, where the method further includes:

step 61, sending information of an indication mode; wherein, the instruction mode includes:

a first indication mode for indicating common Downlink Control Information (DCI) explicit indication information;

and the second indication mode is used for indicating the implicit indication information of the common Downlink Control Information (DCI).

In one embodiment, in response to the indication mode being the first indication mode, the common Downlink Control Information (DCI) carries time-frequency domain location information for transmitting the dedicated Downlink Control Information (DCI) in the time slot;

or,

in response to the indication mode being the second indication mode, the common Downlink Control Information (DCI) implicitly indicates that the time-frequency domain position for transmitting the dedicated Downlink Control Information (DCI) in the time slot is the same as the time-frequency domain position for transmitting the common Downlink Control Information (DCI).

In an embodiment, the common Downlink Control Information (DCI) explicitly indicates that the indication information may be a field where the common Downlink Control Information (DCI) carries a symbol position and a frequency domain position in a timeslot corresponding to transmission-specific Downlink Control Information (DCI).

In one embodiment, the indication information is valid for all N Transport Blocks (TBs) that are jointly scheduled. That is, the dedicated Downlink Control Information (DCI) for all Transport Blocks (TBs) is transmitted at the symbol position and the frequency domain position within the indicated slot.

In one embodiment, dedicated Downlink Control Information (DCI) for a first Transport Block (TB) that is jointly scheduled is transmitted on a time slot adjacent to common Downlink Control Information (DCI).

Referring to fig. 7, in the embodiment of the present disclosure, for the first indication manner, transmission resources of common Downlink Control Information (DCI) and dedicated Downlink Control Information (DCI) may be configured independently, which can effectively reduce the probability of generating control channel blocking in a user-specific search space (USS).

In one embodiment, in order to reduce the overhead of Control signaling, a Channel format of a Physical Downlink Control Channel (PDCCH) carrying dedicated downlink Control information may be consistent with a Channel format of a physical downlink Control Channel of common downlink Control information, that is, the Physical Downlink Control Channel (PDCCH) carrying dedicated Downlink Control Information (DCI) uses the same aggregation level and the same Control Channel Element (CCE) interleaving manner (including configuration of parameters required for interleaving) as the common Downlink Control Information (DCI).

In an embodiment, the common Downlink Control Information (DCI) implicitly indicates that the indication information may be a field where the common Downlink Control Information (DCI) does not carry a symbol position and a frequency domain position in a time slot corresponding to transmission-specific Downlink Control Information (DCI). Here, the symbol position and the frequency domain position of the dedicated Downlink Control Information (DCI) in the slot are the same as those of the common downlink control information in the slot.

In one embodiment, in order to reduce the processing complexity of the terminal while considering the transmission delay, the dedicated Downlink Control Information (DCI) of the first Transport Block (TB) of the joint scheduling is transmitted on a time slot adjacent to the common Downlink Control Information (DCI). In the second indication mode, the dedicated Downlink Control Information (DCI) occupies the position of a candidate channel in the dedicated search space (USS), so that Downlink Control Information (DCI) for other services of the same terminal and other terminals do not use the time-frequency domain resource position in the corresponding time slot.

In one embodiment, in order to reduce the complexity of the device performing the blind detection of the common Downlink Control Information (DCI), the two modes are not supported to be used simultaneously. That is, during uplink and downlink transmission within a period of time, the terminal selects the first indication mode or the second indication mode to determine the time-frequency domain position of the dedicated Downlink Control Information (DCI).

In one embodiment, a base station determines an independent configuration of dedicated Downlink Control Information (DCI) and a user-specific search space (USS). In one embodiment, the base station may perform resource adjustment for allocation in real time according to specific use conditions of physical resources.

In one embodiment, the sending the information indicating the manner includes:

Here, the indication scheme is carried in a Radio Resource Control (RRC) message, which can improve signaling compatibility of the Radio Resource Control (RRC) message.

In one embodiment, in response to the indication being the first indication, a time-frequency domain location of a user-specific search space (USS) used to carry common Downlink Control Information (DCI) is different from a time-frequency domain location of transmission-specific Downlink Control Information (DCI). Here, the time-frequency domain position of the user-specific search space (USS) for carrying the common Downlink Control Information (DCI) may not overlap with the time-frequency domain position of the transmission-specific Downlink Control Information (DCI). In this way, resource blocking situations can be reduced.

In one embodiment, dedicated Downlink Control Information (DCI) for a first transmitted Transport Block (TB) of a plurality of Transport Blocks (TBs) is transmitted on a slot adjacent to a slot in which common Downlink Control Information (DCI) is transmitted. Here, since the dedicated Downlink Control Information (DCI) of the first transmitted Transport Block (TB) can be transmitted on a slot adjacent to the slot of the common Downlink Control Information (DCI), transmission delay can be reduced.

In one embodiment, the common Downlink Control Information (DCI) includes: carrying a time slot position relation indication between the special Downlink Control Information (DCI); a slot position indication for indicating a transmission mode of transmission of the dedicated Downlink Control Information (DCI).

A transmission mode for transmitting dedicated Downlink Control Information (DCI), comprising:

the first transmission mode is as follows: the special DCI of each Transmission Block (TB) is transmitted on discontinuous time slots in sequence;

Here, the discontinuous time slots are spaced at least one time slot apart. In one embodiment, the number of slots of the non-consecutive inter-slot intervals is the same.

In one embodiment, in response to the transmission mode of the transmission dedicated Downlink Control Information (DCI) being the first transmission mode, the dedicated Downlink Control Information (DCI) of the nth Transport Block (TB) is transmitted at the first time slot after the time slot of the (N-1) th Transport Block (TB) is transmitted; wherein N is a positive integer and N is the number of the plurality of Transport Blocks (TBs).

Referring to fig. 8, in one embodiment, the transmission of the Transport Block (TB) is a cross-slot transmission, and the dedicated Downlink Control Information (DCI) of the nth Transport Block (TB) is transmitted in the first slot after the end of the transmission of the (n-1) th Transport Block (TB). In the method, the requirement on the complexity of the terminal is low, but the transmission delay is large, so that the method can be suitable for services and/or terminals which can tolerate long delay.

Referring to fig. 9, in one embodiment, the transmission of the Transport Block (TB) is a cross-slot transmission, and the dedicated Downlink Control Information (DCI) is transmitted in consecutive slots sequentially. The method has lower transmission delay and is suitable for delay-sensitive services and/or equipment.

Referring to fig. 10, in one embodiment, the transmission of the Transport Block (TB) is a simultaneous slot transmission, and the dedicated Downlink Control Information (DCI) is transmitted sequentially in consecutive slots.

In one embodiment, dedicated Downlink Control Information (DCI) carries a symbol position indication; a symbol position indication for indicating a starting symbol position and a symbol length for transmitting the Transport Block (TB) within the slot. Thus, after receiving the dedicated Downlink Control Information (DCI), the terminal may receive the Transport Block (TB) at the time domain position corresponding to the start symbol position and the symbol length indicated by the symbol position according to the symbol position indication.
