In order to better understand a hybrid automatic repeat request HARQ process allocation method disclosed in the embodiments of the present application, a communication system to which the embodiments of the present application are applicable is first described below.

Referring to fig. 1, fig. 1 is a schematic architecture diagram of a communication system according to an embodiment of the present application. The communication system may include, but is not limited to, one network device and one terminal device, and the number and form of devices shown in fig. 1 are only used as examples and not limiting to the embodiments of the present application, and may include two or more network devices and two or more terminal devices in practical applications. The communication system shown in fig. 1 is exemplified as including a network device 101 and a terminal device 102.

It should be noted that the technical solution of the embodiment of the present application may be applied to various communication systems. For example: a long term evolution (Long Term Evolution, LTE) system, a fifth generation mobile communication system, a 5G new air interface system, or other future new mobile communication systems, etc.

The network device 101 in the embodiment of the present application is an entity on the network side for transmitting or receiving signals. For example, the network device 101 may be an Evolved NodeB (eNB), a transmission point (Transmission Reception Point, TRP), a Next Generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems or an access node in a wireless fidelity (Wireless Fidelity, wiFi) system, etc. The embodiment of the application does not limit the specific technology and the specific device form adopted by the network device. The network device provided in this embodiment of the present application may be composed of a Central Unit (CU) and a Distributed Unit (DU), where the CU may also be referred to as a Control Unit (Control Unit), and the structure of the CU-DU may be used to split the protocol layers of the network device, for example, a base station, where functions of part of the protocol layers are placed in the CU for centralized Control, and functions of part or all of the protocol layers are Distributed in the DU for centralized Control of the DU by the CU.

The terminal device 102 in this embodiment of the present application is an entity on the user side for receiving or transmitting signals, such as a mobile phone. The Terminal device may also be referred to as a Terminal device (Terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal device (MT), etc. The terminal device may be an automobile with a communication function, a Smart car, a Mobile Phone, a wearable device, a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented Reality (Augmented Reality, AR) terminal device, a wireless terminal device in industrial control (Industrial Control), a wireless terminal device in Self-Driving (Self-Driving), a wireless terminal device in teleoperation (Remote Medical Surgery), a wireless terminal device in Smart Grid (Smart Grid), a wireless terminal device in transportation security (Transportation Safety), a wireless terminal device in Smart City (Smart City), a wireless terminal device in Smart Home (Smart Home), or the like. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the terminal equipment.

The terminal device 102 may directly send small data to the network device 101 through a dedicated PUSCH resource configured by the network device 101, i.e. a configuration grant CG (Configure Grant) or a pre-allocated uplink resource PUR (Preallocated Uplink Resource), while in an IDLE state (IDLE)/INACTIVE state (INACTIVE). The network device 101 configures, to the terminal device 101, an uplink resource used when in an idle state/inactive state and a cell and BWP (BandWidth Part) where the uplink resource is located, by an RRC Release (Radio Resource Control Release) message. The network device 101 allocates the uplink resource to the terminal device 102 by means of periodic allocation. Meanwhile, the network device 101 also allocates a hybrid automatic repeat request HARQ process for the uplink resource of each period, so as to ensure that the terminal device 102 can use different HARQ processes to buffer data on different resources for data retransmission.

The network device 101 may send different signals through different downlink beams, and when the terminal device 102 sends an uplink signal through the uplink resource in the idle state/inactive state, the network device 101 needs to know that the terminal device 102 can currently receive downlink beam information of the signal, so as to send downlink data and control signaling to the terminal device 102 through the corresponding downlink beam. Therefore, the uplink resources used by the terminal device 102 for transmitting the uplink signal need to be bound with the corresponding downlink beams, so that when the network device 101 receives the signal on the uplink resources, the beam on which the terminal device 102 can receive the downlink signal can be known. Multiple cycles of uplink resources may be bonded with multiple downlink beams. When transmitting data, before selecting uplink resources, the terminal device 102 needs to select a downlink beam meeting the channel quality requirement, and then select uplink resources corresponding to the beam for uplink transmission.

In the related art, the network device 101 allocates one HARQ process for each uplink resource, and in the case of configuring a plurality of HARQ processes together, the HARQ processes are allocated according to the uplink resource cycle sequence, for example, the network device 101 allocates 4 HARQ processes to the terminal device 102 in total, and 1 HARQ process is allocated per uplink resource cycle, and the HARQ process number is allocated in each uplink resource cycle according to the cycle number sequence (cycle 1/2/3/4/5/6/7/8) (1/2/3/4/1/2/3/4).

If the uplink resources of multiple periods are bonded with multiple beams, the terminal device 102 only selects 1 beam and transmits the uplink resources of 1 period corresponding to the beam when actually transmitting, that is, the terminal device 102 only uses 1 HARQ process, and the HARQ processes of other uplink resource periods are idle. Further, when the terminal device 102 performs uplink data transmission again, after the terminal device 102 selects 1 beam again, the HARQ process number of the periodic uplink resource corresponding to the beam may collide with the HARQ process number of the periodic uplink resource of the previous data transmission, thereby causing new data to cover the data of the previous data transmission in the same HARQ process, resulting in failure of retransmission of the data of the previous data transmission and failure of data transmission.

In the embodiment of the application, through receiving the association relation between the uplink resource and the beam configured by the network equipment, according to the association relation, the corresponding hybrid automatic repeat request HARQ process is allocated to the uplink resource, and the HARQ process number can be allocated according to the association relation between the uplink resource and the beam, so that the HARQ process conflict during data transmission is avoided, the HARQ process waste caused by the excessive allocation of the HARQ process number can be avoided, the cost is reduced, the resource is saved, and the efficiency and the reliability of data transmission are improved.

It may be understood that, the communication system described in the embodiments of the present application is for more clearly describing the technical solution of the embodiments of the present application, and is not limited to the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the system architecture and the appearance of a new service scenario, the technical solution provided in the embodiments of the present application is equally applicable to similar technical problems.

The following describes in detail the HARQ process allocation method and apparatus provided in the present application with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flow chart of a hybrid automatic repeat request HARQ process allocation method according to an embodiment of the present application. It should be noted that, the HARQ process allocation method according to the embodiment of the present application is performed by the terminal device. As shown in fig. 2, the method may include the steps of:

Step 201, receiving an association relationship between an uplink resource configured by a network device and a beam.

The uplink resource is a physical uplink shared channel PUSCH resource configured by the network device, and the beam is a beam adopted by the network device for transmitting downlink data.

Optionally, the uplink resource is a configuration grant CG (Configure Grant) or a pre-allocated uplink resource PUR (Preallocated Uplink Resource); the identification of the beam includes at least one of an SSB (Synchronous Signal Block, synchronization signal block) identification and a CSI-RS (Channel State Information Reference Signal ) identification.

In some embodiments, the association is: at least one beam corresponds to at least one uplink resource.

Wherein one synchronization signal block SSB burst transmission period may include at least one synchronization signal block SSB burst. The numbering of the plurality of consecutive beams in one SSB burst may be discontinuous because the numbering of one beam may correspond to the numbering of one or more SSBs, e.g., in one SSB burst, there are 8 SSBs, numbered 0-7, respectively, but there may be four beams in this burst, numbered 1/2/3/4/1/2/3/4, and thus the numbering of the plurality of consecutive beams in this burst may be 2/3/4/1. The number of the beam, i.e. the identity of the beam.

The at least one uplink resource in one uplink resource period may be at least one frequency domain resource in one uplink resource period, at least one time domain resource in one uplink resource period, or at least one DMRS (Demodulation Reference Signal, demodulation signal) resource in one uplink resource period.

Optionally, when the uplink resource is a frequency domain resource, PRBs (Physical Resource Block ) of each uplink resource are different; when the uplink resource is a time domain resource, the time slot or symbol of each uplink resource is different; when the uplink resource is a DMRS resource, DMRS corresponding to each uplink resource is different.

As a first possible implementation manner, the association relationship is: at least one beam in one synchronization signal block SSB burst corresponds to an uplink resource in at least one uplink resource period.

As a second possible implementation manner, the association relationship is: at least one beam in one synchronization signal block SSB burst corresponds to at least one uplink resource in one uplink resource period.

As a third possible implementation manner, the association relationship is: at least one beam in one synchronization signal block SSB burst corresponds to at least one uplink resource in a consecutive plurality of uplink resource periods.

It is to be understood that the association relationship between the at least one beam and the at least one uplink resource may be any one of the association relationships between the at least one beam and any one of the uplink resources, where only three exemplary embodiments are written, and the remaining corresponding association relationships are similar to the written exemplary three, so that no list is given.

Step 202, according to the association relation, the corresponding hybrid automatic repeat request HARQ process is allocated for the uplink resource.

In some embodiments, the allocation method is: the same HARQ process is allocated for at least one uplink resource corresponding to at least one beam. That is, the HARQ process on the at least one uplink resource corresponding to the at least one beam is the same.

As a first possible implementation, the HARQ processes on the uplink resources in at least one uplink resource period corresponding to at least one beam in one synchronization signal block SSB burst are the same.

As a second possible implementation, the HARQ process on at least one uplink resource in one uplink resource period corresponding to at least one beam in one synchronization signal block SSB burst is the same.

As a third possible implementation manner, the HARQ process on at least one uplink resource in a continuous plurality of uplink resource periods corresponding to at least one beam in one synchronization signal block SSB burst is the same.

It can also be appreciated that the method of allocating HARQ processes for uplink resources according to the remaining corresponding associations is not listed again, similar to the three exemplary embodiments written.

In some embodiments, the method further comprises determining an allocation of hybrid automatic repeat request HARQ processes according to a configuration or protocol convention of the network device.

When the allocation method is determined to be the first allocation method, the allocation method is as follows: the same HARQ process is allocated for at least one uplink resource corresponding to at least one beam.

When the allocation method is determined to be the second allocation method, the allocation method is as follows: one HARQ process is allocated for each uplink resource period.

In some embodiments, under the condition that the association relationship between the uplink resource and the beam configured by the network device is received, determining that the hybrid automatic repeat request HARQ process allocation manner is a first allocation manner.

In some embodiments, when an association relationship between an uplink resource configured by the network device and a beam is received and the uplink resource is used for small data transmission SDT, determining that the HARQ process allocation manner is a first allocation manner.

In some embodiments, the hybrid automatic repeat request HARQ process allocation manner is determined to be the second allocation manner in a case where an association between an uplink resource configured by the network device and a beam is not received, or the uplink resource is not used for small data transmission SDT.

In summary, by receiving the association relationship between the uplink resource and the beam configured by the network device, and allocating the corresponding hybrid automatic repeat request HARQ process to the uplink resource according to the association relationship, the HARQ process number can be allocated according to the association relationship between the uplink resource and the beam, so as to avoid the HARQ process conflict during data transmission, avoid the HARQ process waste caused by the allocation of too many HARQ process numbers, reduce the overhead, save the resource, and improve the efficiency and reliability of data transmission.

Referring to fig. 3, fig. 3 is a flowchart of a hybrid automatic repeat request HARQ process allocation method according to an embodiment of the present application. It should be noted that, the HARQ process allocation method according to the embodiment of the present application is performed by the terminal device. As shown in fig. 3, the method may include the steps of:

step 301, receiving an association relationship between at least one beam configured by the network device and at least one uplink resource.

The at least one uplink resource is any one of the following: uplink resources in at least one uplink resource period; at least one uplink resource in one uplink resource period; at least one uplink resource of the plurality of uplink resource periods is continued.

In this embodiment of the present application, the association relationship is an association relationship between any one of the beams and any one of the uplink resources.

It will be appreciated that the remaining associations are similar to the three exemplary ones written, and are not listed here.

Step 302, determining a hybrid automatic repeat request HARQ process allocation manner according to the configuration or protocol convention of the network device.

Optionally, the hybrid automatic repeat request HARQ process allocation is implicitly indicated according to the configuration of the network device.

In step 303, when it is determined that the HARQ process allocation manner is the first allocation manner, the corresponding HARQ process is allocated for the uplink resource according to the association relationship between at least one beam and at least one uplink resource.

In this embodiment of the present application, according to an association relationship between at least one beam and at least one uplink resource, a corresponding hybrid automatic repeat request HARQ process is allocated for the uplink resource, including: the same HARQ process is allocated for at least one uplink resource corresponding to at least one beam. That is, the HARQ process on the at least one uplink resource corresponding to the at least one beam is the same.

It may also be appreciated that, similar to the written exemplary embodiment, the method for allocating HARQ processes to uplink resources according to the remaining corresponding association relationships is not listed.

In some embodiments, the network device configures a plurality of HARQ processes for the terminal device, and the terminal device sequentially allocates the HARQ processes according to the association relationship and the sequence of the HARQ process numbers.

The detailed description will be given taking the association relationship as an example of "at least one beam in one synchronization signal block SSB burst set corresponds to an uplink resource in at least one uplink resource period", and the other association relationships are similar and are not listed here. For convenience of description, the association relationship is that "N beams in one synchronization signal block SSB burst set correspond to uplink resources in M uplink resource periods".

The period of the uplink resource is T, which is configured by the network device to the terminal device, and the counting unit of the period configuration identifier is symbol, that is, the number of symbols in the configuration period T can be understood as that the counting unit of the period T is symbol. The association period of the N beams with the uplink resource in the M periods is referred to as 1 SSB association period, which is expressed as ssbsassocionperiod=m×t. The HARQ processes on the uplink resource in 1 SSB association period are the same, i.e., the HARQ of the uplink resource allocation for each of the M uplink resource periods is the same in 1 SSB association period. If the network device configures a plurality of HARQ processes for the terminal device, the HARQ processes are sequentially allocated according to the order of SSB association periods and the order of HARQ process numbers, for example, the HARQ process number allocated for M uplink resource periods in the first SSB association period is 1, the HARQ process number allocated for M uplink resource periods in the second SSB association period is 2, and so on.

The method for calculating the HARQ process number of the terminal equipment for the uplink resource configuration comprises the following steps:

assuming that the number of available HARQ Processes is nrofHARQ-process, the starting number of the HARQ process is HARQ-ProcID-Offset (may be an integer with a value greater than or equal to 0), the number of the HARQ process allocated for the starting periodic uplink resource (or any periodic uplink resource of the M periodic uplink resources) in the M periodic uplink resources in each SSB association period is:

HARQ Process ID＝[floor(CURRENT_symbol/ssbAssocationPeriod)mod nrofHARQ-Processes+harq-ProcID-Offset]。

Wherein floor represents a downward rounding, mod represents a remainder, current_symbol represents a CURRENT symbol, and the calculation method is as follows: current_symbol= (sfn×number ofslotsperframe×number ofsymbol perslot+ slot number in the frame ×number ofsymbol perslot+ symbol number in the slot)

Where SFN (System Frame Number) denotes the system frame number, numberOfSlotsPerFrame denotes the number of consecutive slots in each frame, numberofsymbol perslot denotes the number of consecutive symbols per slot, slot number in the frame denotes the number of the current slot in the frame, and symbol number in the slot denotes the number of the current symbol in the slot.

It can be understood that, in the M periods, the HARQ process number of each period of the remaining M-1 other than the start period (or any one of the M period uplink resources) is the same as the HARQ process number of the start period (or any one of the M period uplink resources).

Step 304, in the case that the hybrid automatic repeat request HARQ process allocation manner is determined to be the second allocation manner, allocating a hybrid automatic repeat request HARQ process for each uplink resource period.

Referring to fig. 4, fig. 4 is a flowchart of a hybrid automatic repeat request HARQ process allocation method according to an embodiment of the present application.

As a first possible implementation manner, the association relationship of the configuration sent to the terminal device is: at least one beam in one synchronization signal block SSB burst corresponds to an uplink resource in at least one uplink resource period for allocating the same HARQ process for the uplink resource in the at least one uplink resource period corresponding to the at least one beam in one synchronization signal block SSB burst.

It can also be understood that, the method of sending the configured remaining association relationship to the terminal device so that the terminal device allocates the corresponding hybrid automatic repeat request HARQ process for the uplink resource according to the association relationship is similar to the written exemplary three methods, and is not listed one by one.

In some embodiments, in a case that the hybrid automatic repeat request HARQ process allocation manner is determined to be the first allocation manner, the configured association relationship between at least one beam and at least one uplink resource is sent to the terminal device.

In some embodiments, the HARQ process allocation means further includes a second allocation means for allocating a HARQ process for each uplink resource period.

In some embodiments, the network device sends the association to the terminal device through an RRC Release message.

In summary, by configuring the association relationship between the uplink resource of the terminal device and the beam, the association relationship is sent to the terminal device, so that the terminal device allocates the corresponding hybrid automatic repeat request HARQ process for the uplink resource according to the association relationship, and can allocate the HARQ process number according to the association relationship between the uplink resource and the beam, thereby avoiding the HARQ process conflict during data transmission, avoiding the HARQ process waste caused by the excessive allocation of the HARQ process number, reducing the cost, saving the resource, and improving the efficiency and the reliability of data transmission.

As shown in fig. 5, the method may include the steps of:

In step 501, an association relationship between uplink resources of a terminal device and a beam is configured.

Step 502, in the case that it is determined that the hybrid automatic repeat request HARQ process allocation manner is the first allocation manner, sending, to the terminal device, an association relationship corresponding to the configured at least one beam and the at least one uplink resource.

As a first possible implementation manner, the association relationship of the configuration sent to the terminal device is: at least one beam in one synchronization signal block SSB burst transmission period corresponds to an uplink resource in at least one uplink resource period for allocating the same HARQ process for the uplink resource in at least one uplink resource period corresponding to the at least one beam in one synchronization signal block SSB burst.

As a second possible implementation manner, the association relationship of the configuration sent to the terminal device is: at least one beam in one synchronization signal block SSB burst transmission period corresponds to at least one uplink resource in one uplink resource period for allocating the same HARQ process to at least one uplink resource in one uplink resource period corresponding to at least one beam in one synchronization signal block SSB burst.

As a third possible implementation manner, the association relationship of the configuration sent to the terminal device is: at least one beam in one synchronization signal block SSB burst transmission period corresponds to at least one uplink resource in a consecutive plurality of uplink resource periods for allocating the same HARQ process for the at least one uplink resource in the consecutive plurality of uplink resource periods corresponding to the at least one beam in one synchronization signal block SSB burst.

In summary, by configuring the association relationship between the uplink resources of the terminal device and the beams, when determining that the hybrid automatic repeat request HARQ process allocation manner is the first allocation manner, the association relationship corresponding to at least one configured beam and at least one uplink resource is sent to the terminal device, so that the HARQ process number can be allocated according to the association relationship between the uplink resources and the beams, thereby avoiding the HARQ process conflict during data transmission, avoiding the HARQ process waste caused by the allocation of too many HARQ process numbers, reducing the overhead, saving the resources, and improving the efficiency and the reliability of data transmission.
