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, and in particular, but not limited to a method, an apparatus, a communication device, and a storage medium for jointly scheduling a plurality of transport blocks.

Background

In the fifth generation mobile communication technology (5G) networks, new device types, i.e. reduced capability user equipments (Redcap UEs, reduced capability user equipment), are introduced. Reduced capability user equipment (Redcap UE) is typically required to meet the following requirements: 1. low cost and low complexity; 2. coverage enhancement; 3. power saving. Since the New air interface (NR) is designed for high-end terminals with high rate and low delay, the above requirements cannot be met. Therefore, a need exists for a new air interface (NR) system retrofit to meet the above-described requirements.

In the related art, for uplink and downlink transmission, a base station schedules physical resources, modulation coding formats, and the like required for a transport block (TB, transmission Block) through downlink control information (DCI, downlink Control Information) signaling. Since the terminal cannot know the specific bearing position of the Downlink Control Information (DCI), the terminal needs to perform blind detection in the search space when receiving the Downlink Control Information (DCI). Therefore, the blind detection of the terminal is high in complexity, multiple blind detection is needed, the power consumption of the terminal can be increased due to the excessive blind detection times, and the requirement of power saving cannot be met.

The base station 120 may be a network-side device in a wireless communication system. Wherein the wireless communication system may be a fourth generation mobile communication technology (the 4th generation mobile communication,4G) system, also known as a long term evolution (Long Term Evolution, LTE) system; alternatively, the wireless communication system may be a 5G system, also known as a new air interface system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. Among them, the access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network, new Generation radio access network).

Here, the above-described user equipment can be regarded as the terminal equipment of the following embodiment.

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

Several base stations 120 are respectively connected to a network management device 130. 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 (Mobility Management Entity, MME) in an evolved packet core network (Evolved Packet Core, EPC). Alternatively, the network management device may be other core network devices, such as a Serving GateWay (SGW), a public data network GateWay (Public Data Network GateWay, PGW), a policy and charging rules function (Policy and Charging Rules Function, PCRF) or a home subscriber server (Home Subscriber Server, HSS), etc. The embodiment of the present disclosure is not limited to the implementation form of the network management device 130.

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

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

Similar to the internet of things devices in long term evolution wireless communication systems, reduced capability user equipment (Redcap UE) is typically required to meet the following requirements: 1. low cost and low complexity; 2. coverage enhancement; 3. power saving. Since the new air interface (NR) is designed for high-end terminals with high rate and low delay, the above requirements cannot be met. There is therefore a need to retrofit new air interface (NR) systems to meet the above requirements. For example, to meet low cost and low complexity requirements, the radio frequency bandwidth of reduced capability user equipment (Redcap UE) may be limited; such as to 5 mhz or 10 mhz, or to the size of the buffer of the reduced capability user equipment (Redcap UE), and thus to the size of the Transport Block (TB) per reception, etc. For power saving, possible optimization directions are to simplify the communication flow, reduce the number of times the reduced capability user equipment (Redcap UE) detects the downlink control channel, etc.

In one embodiment, for uplink and downlink transmissions, a base station schedules physical resources and modulation coding formats required for a Transport Block (TB) and the like through Downlink Control Information (DCI) signaling. The base station may perform the scheduling of the same time slot, see fig. 2. The base station may also perform cross-slot scheduling, see fig. 3. In one embodiment, the transmission of Downlink Control Information (DCI) has a plurality of physical downlink control channel (PDCCH, physical Downlink Control Channel) candidate locations located in a search space configured by a base station to the base station through higher layer Radio Resource Control (RRC) signaling. Since the terminal does not know the specific bearing position of the Downlink Control Information (DCI), the terminal needs to perform blind detection in the dedicated search space when receiving the Downlink Control Information (DCI). This approach greatly increases the flexibility of base station scheduling while reducing the probability of Physical Downlink Control Channel (PDCCH) blocking. The simultaneous slot transmission may be that a time slot for transmitting the Transport Block (TB) and a time slot for transmitting Downlink Control Information (DCI) of the Transport Block (TB) belong to the same time slot. The cross-slot transmission may be at least one slot spaced between a slot transmitting the Transport Block (TB) and a slot transmitting Downlink Control Information (DCI) of the Transport Block (TB).

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

step 41, downlink Control Information (DCI) of a plurality of Transport Blocks (TBs) is issued.

Wherein, downlink Control Information (DCI) includes: common Downlink Control Information (DCI) and a plurality of dedicated Downlink Control Information (DCI) in one-to-one correspondence with a plurality of Transport Blocks (TBs); common Downlink Control Information (DCI) carrying indication information of a time-frequency domain location for transmitting dedicated Downlink Control Information (DCI); common Downlink Control Information (DCI) 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, the Downlink Control Information (DCI) receiving the 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, etc. Here, the terminal may be a reduced capability user equipment (Redcap UE).

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

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

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

The uplink transmission schedule may be simply referred to as an uplink schedule; the foregoing downlink transmission schedule may be simply referred to as a downlink schedule.

In one embodiment, the Downlink Control Information (DCI) may be indicated as information for performing downlink scheduling or as information for performing uplink scheduling by a format indication that distinguishes between uplink scheduling and downlink scheduling. For example, when the bit value of the format indication corresponding field that distinguishes between uplink scheduling and downlink scheduling is "0", downlink Control Information (DCI) is information that instructs the terminal to perform uplink scheduling. When the bit value of the format indication corresponding field for distinguishing the uplink scheduling and the downlink scheduling is 1, the Downlink Control Information (DCI) is information for indicating the terminal to perform 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 certain specific Transport Block (TB).

In one embodiment, the format indication distinguishing between uplink and 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 a jointly scheduled number of Transport Blocks (TBs).

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

In one embodiment, the time-frequency domain location may include a time domain location where dedicated Downlink Control Information (DCI) is transmitted. The time domain position may comprise a position of a slot and/or a position of a 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 location of the time slot may be indicated by a dedicated Downlink Control Information (DCI) time domain location indication, which may be carried in the common Downlink Control Information (DCI). In one embodiment, the location of symbols in the time domain may be indicated by a dedicated Downlink Control Information (DCI) symbol location indication, which may be carried in common Downlink Control Information (DCI).

In one embodiment, the time-frequency domain location may include a frequency domain location where dedicated Downlink Control Information (DCI) is transmitted. The frequency domain location 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 the plurality of Transport Blocks (TBs) may be a simultaneous slot transmission. Referring again to fig. 2, the simultaneous slot transmission may be that a slot transmitting the Transport Block (TB) and a slot transmitting dedicated Downlink Control Information (DCI) of the Transport Block (TB) belong to the same slot.

In one embodiment, the transmission of the plurality of 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 transmitting the Transport Block (TB) and a slot transmitting dedicated Downlink Control Information (DCI) of the Transport Block (TB).

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

In one embodiment, common Downlink Control Information (DCI) carries a slot position indication of dedicated Downlink Control Information (DCI). The time slot position indication of the dedicated Downlink Control Information (DCI) is used to indicate a time slot position relationship between transmitting different dedicated Downlink Control Information (DCI).

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 a plurality of Transport Blocks (TBs) is scheduling information that is needed for transmitting all of the plurality of Transport Blocks (TBs). The scheduling information for a single Transport Block (TB) is scheduling information that is required for transmitting the corresponding Transport Block (TB).

In one embodiment, referring to fig. 5, n transport blocks to be scheduled are transport block TB1, transport block TB2, transport block TB3, transport blocks TB4, …, and transport block TBn, respectively. G1 is common Downlink Control Information (DCI) of transport blocks TB1 to 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 disclosure, since the common Downlink Control Information (DCI) carries the indication information of the time-frequency domain position of the transmission dedicated Downlink Control Information (DCI), the terminal can obtain the time-frequency domain position of the transmission dedicated Downlink Control Information (DCI) according to the indication information of the common Downlink Control Information (DCI) after receiving the common Downlink Control Information (DCI). In this way, when receiving the dedicated Downlink Control Information (DCI), the terminal does not need to perform blind detection any more, and can receive the dedicated Downlink Control Information (DCI) at the time-frequency domain position indicated by the common Downlink Control Information (DCI). Compared with a mode that all Downlink Control Information (DCI) is required to be subjected to blind detection when the Downlink Control Information (DCI) is received, the number of times of blind detection when the Downlink Control Information (DCI) is received can be reduced, the complexity of blind detection is reduced, and the power consumption caused by the blind detection is reduced.

In one embodiment, common Downlink Control Information (DCI) is issued before 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 instruction information of the time-frequency domain position carried in the received common Downlink Control Information (DCI).

In one embodiment, common Downlink Control Information (DCI) includes at least one of: format indication for distinguishing uplink scheduling and downlink scheduling, bandwidth part (BWP) indication, number of Transport Blocks (TBs) for joint scheduling, hybrid automatic repeat request (HARQ) start process number, and slot offset indication.

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

In one embodiment, dedicated Downlink Control Information (DCI) includes at least one of: modulation and coding scheme information (MCS) and time-frequency domain resource allocation information.

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

In one embodiment, common Downlink Control Information (DCI) includes: common Downlink Control Information (DCI) for uplink scheduling and common Downlink Control Information (DCI) for downlink scheduling; wherein, the number of bits of the common Downlink Control Information (DCI) for uplink scheduling is the same as the number of bits of the common Downlink Control Information (DCI) for downlink scheduling.

Here, common Downlink Control Information (DCI) for uplink scheduling is used to schedule uplink Transport Blocks (TBs). 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 number of bits of the common Downlink Control Information (DCI) for downlink are made the same by filling "0" in bits of the common downlink control information, so as to reduce complexity in blind detection of the common Downlink Control Information (DCI).

As shown in fig. 6, in this embodiment, a method for jointly scheduling a plurality of transport blocks is provided, where the method further includes:

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

a first indication mode, configured to indicate common Downlink Control Information (DCI) explicit indication information;

and a second indication mode, configured to indicate common Downlink Control Information (DCI) implicit indication information.

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 dedicated Downlink Control Information (DCI) within the time slot;

or alternatively, the process may be performed,

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

In one embodiment, the explicit indication of the common Downlink Control Information (DCI) may be a field where the common Downlink Control Information (DCI) carries a symbol position and a frequency domain position in a slot corresponding to the transmission dedicated Downlink Control Information (DCI).

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

In one embodiment, dedicated Downlink Control Information (DCI) of a first Transport Block (TB) of a joint schedule 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, to reduce the overhead of control signaling, the channel format of the Physical Downlink Control Channel (PDCCH) carrying the dedicated downlink control information may be kept consistent with the channel format of the physical downlink control channel carrying the common downlink control information, i.e., the Physical Downlink Control Channel (PDCCH) carrying the dedicated Downlink Control Information (DCI) uses the same aggregation level as the common Downlink Control Information (DCI), the same control channel element (CCE, control Channel Element) interleaving manner (including configuration of parameters required for interleaving), and so on.

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

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

In one embodiment, to reduce the complexity of the device for blind detection of common Downlink Control Information (DCI), two modes are not supported for simultaneous use. That is, in uplink and downlink transmission within a period of time, the terminal selects the first indication scheme or the second indication scheme 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 user-specific search spaces (USSs). In one embodiment, the base station may adjust the allocated resources in real time according to the specific usage of the physical resources.

In one embodiment, in response to the indication manner being the first indication manner, a time-frequency domain location of a user-specific search space (USS) for carrying common Downlink Control Information (DCI) is different from a time-frequency domain location of transmitting the dedicated 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) of a Transport Block (TB) transmitted from a first one of a plurality of Transport Blocks (TBs) is transmitted on adjacent slots of a slot in which common Downlink Control Information (DCI) is transmitted. Here, since dedicated Downlink Control Information (DCI) of a Transport Block (TB) of a first transmission can be transmitted on adjacent slots of a slot of common Downlink Control Information (DCI), a transmission delay can be reduced.

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

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

the second transmission mode: dedicated Downlink Control Information (DCI) for each Transport Block (TB) is sequentially transmitted in consecutive slots.

Here, the non-consecutive slots are separated by at least one slot. In one embodiment, the number of time slots in the non-contiguous inter-slot space is the same.

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

Referring to fig. 8, in one embodiment, the transmission of the Transport Block (TB) is cross-slot transmission, and the dedicated Downlink Control Information (DCI) of the nth Transport Block (TB) is transmitted on the first slot after the end of transmission with the (n-1) th Transport Block (TB). The complexity requirement on the terminal is lower in the mode, but the transmission delay is larger, and the method is applicable to the service and/or the terminal which can tolerate long delay.

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

Referring to fig. 10, in one embodiment, transmission of a Transport Block (TB) is a simultaneous slot transmission, and dedicated Downlink Control Information (DCI) is sequentially transmitted on 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 of transmission of the Transport Block (TB) within the slot. In this way, after receiving the dedicated Downlink Control Information (DCI), the terminal can 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.
