Description

HARQ-ACK feedback method and related product

Technical Field

The present application relates to the field of communication processing technologies, and in particular, to a HARQ-ACK feedback method and a related product.

Background

HARQ (Hybrid Automatic Repeat request) is a technology combining fec (forward Error correction) and arq (Automatic Repeat request) methods. The FEC adds redundant information to enable the receiving end to correct a part of errors, so as to reduce the number of retransmissions. The receiving end uses an error detection code, usually a Cyclic Redundancy Check (CRC) Check, to detect whether the received data packet is in error. If there is no error, the receiving end will send a positive Acknowledgement (ACK) to the sending end, and after the sending end receives the ACK, the sending end will send the next data packet. If there is an error, the receiving end discards the data packet and sends a Negative Acknowledgement (NACK) to the transmitting end, and the transmitting end retransmits the same data after receiving the NACK.

In the existing communication, when the UE performs HARQ-ACK feedback, the confirmed PUCCH resource may not be used, which may result in that the HARQ-ACK cannot be fed back, and network performance is affected.

The descriptions of the first, second, etc. appearing in the embodiments of the present application are only for illustrating and differentiating the objects, and do not represent the order or the particular limitation of the number of the devices in the embodiments of the present application, and do not constitute any limitation to the embodiments of the present application. The term "connect" in the embodiments of the present application refers to various connection manners, such as direct connection or indirect connection, to implement communication between devices, which is not limited in this embodiment of the present application.

The technical solution of the embodiment of the present application may be applied to the example communication system 100 shown in fig. 1, where the example communication system 100 includes a terminal 110 and a network device 120, and the terminal 110 is communicatively connected to the network device 120.

The example communication system 100 may be, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an Advanced Long Term Evolution (LTE-a) System, a New Radio (NR) System, an Evolution System of an NR System, an LTE System over unlicensed spectrum (LTE-U), an NR System over unlicensed spectrum (NR-based Access transmitted spectrum, NR-U), a Universal Mobile telecommunications System (Universal Mobile telecommunications System), a UMTS System, or other next generation communication systems.

Generally, conventional Communication systems support a limited number of connections and are easy to implement, however, with the development of Communication technologies, mobile Communication systems will support not only conventional Communication, but also, for example, Device to Device (D2D) Communication, Machine to Machine (M2M) Communication, Machine Type Communication (MTC), and Vehicle to Vehicle (V2V) Communication, etc., and the embodiments of the present application can also be applied to these Communication systems.

A terminal 110 in the embodiments of the subject application may refer to a user equipment, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user device. The terminal may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a relay device, a vehicle-mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved Public Land Mobile Network (PLMN), and the like, which are not limited in this embodiment.

The network device 120 in this embodiment may be a device for communicating with a terminal, where the network device may be an evolved nodeb (eNB or eNodeB) in an LTE system, and may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or the network device may be a relay device, an access point, a vehicle-mounted device, a wearable device, and a network device in a future 5G network or a network device in a future evolved PLMN network, one or a group (including multiple antenna panels) of base stations in a 5G system, or may also be a network node forming a gNB or a transmission point, such as a baseband unit (BBU) or a Distributed Unit (DU), and the present embodiment is not limited.

The CU implements part of the function of the gNB and the DU implements part of the function of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implementing functions of a Radio Resource Control (RRC) layer and a Packet Data Convergence Protocol (PDCP) layer. The DU is responsible for processing a physical layer protocol and a real-time service, and implements functions of a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a Physical (PHY) layer.

HARQ-ACK timing (downlink data scheduling time)

Referring to fig. 2, for a schematic diagram of Downlink data scheduling time, in the 5G NR, units K0 and K1 are slots (slots), K0 represents a time interval between a PDSCH (Physical Downlink Shared Channel) and a PDCCH (Physical Downlink Control Channel), where the PDSCH is used for transmitting Downlink data and the PDCCH is used for transmitting DCI (Downlink Control Information). K1 denotes the time interval of HARQ-ACK feedback and PDSCH.

Semi-Persistent Scheduling (SPS) PDSCH

Semi-persistent scheduling in NR refers to semi-statically configuring radio resources and periodically allocating the resources to a certain UE. The PDCCH scrambled using the SPS C-RNTI designates a radio resource (which is referred to herein as SPS resource) used by the UE, and the UE transmits or receives data using the SPS resource every one cycle. The gNB does not need to re-issue the PDCCH in the time slot to specify the allocated resources, thereby reducing the corresponding PDCCH overhead. After the UE configures SPS, the UE cannot use the SPS, and must use PDCCH scrambled by CS-RNTI (Cell-radio network temporary identifier) for activation. The eNodeB activates/releases the SPS of the UE through the PDCCH scrambled by the SPS C-RNTI.

SPS PDSCH HARQ-ACK codebook

The gNB configures 4 HARQ-ACK bit ranges for the UE at most, and configures one PUCCH resource which can be used for feeding back SPS PDSCH HARQ-ACK in each range, namely, each HARQ-ACK bit range has a unique PUCCH resource.

When only SPS PDSCH HARQ-ACK feedback exists, no scheduling PDCCH or SPS PDSCH activates HARQ-ACK feedback of PDCCH or SPS PDSCH deactivates HARQ-ACK feedback of PDCCH, if a plurality of SPS PDSCHs are configured, the HARQ-ACK bit sequence is as follows: and determining a set of all slot or subslot indexes according to which SPS PDSCHs in the slots/subslots need to be carried by the PUCCH in the slots/subslots, traversing each slot/subslot in the set, arranging HARQ-ACK in the downlink slot according to each { SPS configuration index and serving cell index } in an ascending order, then arranging HARQ-ACK in the SPS configuration index in an ascending order of each serving cell index, and finally arranging HARQ-ACK in the serving cell index in an ascending order.

The UE judges which range is in according to the number of bits fed back on the PUCCH by SPS PDSCH HARQ-ACK, and thereby determines which PUCCH feeds back SPS PDSCH HARQ-ACK.

Referring to fig. 3, fig. 3 provides a feedback method of HARQ-ACK, which may be implemented in the communication system shown in fig. 1, for example, the terminal 110 in the communication system shown in fig. 3 may be a user equipment supporting NR, the network device 120 may be a gNB, of course, according to requirements of different network deployments, the terminal 110 may be directly connected to the gNB through a wireless communication network, of course, the terminal 110 may also pass through a TRP (Transmission and reception point) and the gNB, the TRP may set 1 or more than one TRP according to different application scenarios, a specific structure of the communication system of the present application is only an example for convenience of understanding, and a technical solution of the present application may also not be limited to the architecture of the communication system shown in fig. 1, and the feedback method of HARQ-ACK shown in fig. 3 includes the following steps:

step S301, the network device sends configuration information to the UE, where the configuration information is used to indicate PUCCH resources.

Step S302, UE receives configuration information issued by network equipment;

step S303, the network equipment sends SPS PDSCH to the UE;

step S304, the UE receives the SPS PDSCH sent by the network equipment, and determines SPS PDSCH HARQ-ACK available PUCCH resources according to the configuration information.

For example, the available PUCCH resource may specifically be a single PUCCH resource, for example slot n, or may of course be a set of multiple PUCCH resources (i.e., a PUCCH resource set).

For example, the above steps S302 and S304 may be combined to form a HARQ-ACK feedback method on the UE side, and the above steps S301 and S303 may be combined to form a HARQ-ACK feedback method on the network device side.

According to the feedback method of the HARQ-ACK, the UE determines the available PUCCH resources according to the configuration information of the network equipment, the condition that the HARQ-ACK cannot be fed back due to the fact that the selected PUCCH resources are unavailable is further avoided, and the reliability of the network is improved.

In an optional scheme, when the UE determines that SPS PDSCH HARQ-ACK information PUCCH resources carrying the SPS PDSCH are not available, the method may further include, before determining SPS PDSCH HARQ-ACK available PUCCH resources according to the configuration information:

and the UE receives DCI sent by the network equipment through the PDCCH, wherein a PUCCH resource indication field in the DCI is used for indicating a PUCCH index for feeding back SPS PDSCH HARQ-ACK.

In another optional scheme, when the UE determines that SPS PDSCH HARQ-ACK information PUCCH resources carrying the SPS PDSCH are not available, the method may further include, before determining SPS PDSCH HARQ-ACK available PUCCH resources according to the configuration information:

the UE receives downlink control information DCI transmitted by the network equipment through the PDCCH, wherein the DCI comprises a time slot offset indicating PUCCH resources available from PDSCH to SPS PDSCH HARQ-ACK.

In an alternative and in another alternative,

the PDCCH may be scrambled with SPS PDSCH dedicated RNTI, the NDI of the DCI is set to 1, and the field in the DCI is set to a specific value, and an example of the specific value may be as shown in table 1.

Table 1:

there may be various ways for the UE to determine that SPS PDSCH HARQ-ACK information PUCCH resources carrying the SPS PDSCH are unavailable, as shown in fig. 4, as an example way, referring to fig. 4, in fig. 4, HARQ-ACK of the SPS PDSCH in slot n +2 needs to be fed back at slot n +5, but since slot n +5 is all downlink symbols, the UE cannot perform feedback of SPS PDSCH HARQ-ACK.

Optionally, the configuration information may include: a plurality of HARQ-ACK bit ranges configured for the UE, each HARQ-ACK bit range comprising one SPS PUCCH resource set, the SPS PUCCH resource set comprising at least two SPS PUCCH resources.

Optionally, the determining SPS PDSCH HARQ-ACK available PUCCH resources by the UE according to the configuration information specifically may include:

and the UE determines a first SPS PUCCH resource set corresponding to the total comparison number according to the total bit number, sequentially judges whether the SPS PUCCH resources in the first SPS PUCCH resource set are available according to the identification index, and determines the available PUCCH resources as index0 SPS PUCCH resources if the index0 SPS PUCCH resources are available. If the index0 determines that the SPS PUCCH resource is not available, it is determined whether the SPS PUCCH after the index0 SPS PUCCH is available, for example, it is determined whether the index1 SPS PUCCH resource is available, and if the index1 SPS PUCCH resource is available, it is determined that the available PUCCH resource is the index1 SPS PUCCH resource. If index1 SPS PUCCH resources are not available, the backward judgment is continued until SPS PUCCH resources which can be used are determined.

Step S502, the network equipment sends SPS PUSCH to the UE;

step S503, when the UE determines that SPS PDSCH HARQ-ACK information PUCCH resources bearing the SPS PDSCH are unavailable, the UE receives DCI sent by the network equipment through the PDCCH;

the PDCCH may be scrambled by CS-RNTI, NDI in the DCI is set to 1, and a field in the DCI is set to a specific value, which may be shown in table 1.

Step S504, the UE determines available PUCCH resources according to the DCI and the configuration information.

For example, the implementation manner of the step S504 may specifically include:

and the UE determines the PUCCH index of the feedback SPS PDSCH HARQ-ACK according to the PUCCH resource indication field in the DCI, namely the PUCCH index of the PUCCH resource set corresponding to the total bit range.

For example, the implementation manner of step S504 may specifically include:

and the UE indicates the time slot offset from the PDSCH to the HARQ-ACK PUCCH according to the DCI.
