Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided by the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided by the embodiments of the present application is applicable to similar technical problems.

Referring to fig. 1, a schematic diagram of a network architecture 100 according to an embodiment of the application is shown. The network architecture 100 may include: terminal device 10, access network device 20, and core network device 30.

The terminal device 10 may refer to a UE (User Equipment), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a wireless communication device, a User agent, or a User Equipment. Alternatively, the terminal device 10 may also be a cellular phone, a cordless phone, a SIP (Session Initiation Protocol ) phone, a WLL (Wireless Local Loop, wireless local loop) station, a PDA (Personal digital Assistant), a handheld device with a wireless communication function, a computing device, or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in 5GS (5 th Generation System, fifth generation mobile communication system), or a terminal device in a future evolved PLMN (Pub 1ic Land Mobi1e Network), or the like, which the embodiment of the present application is not limited. For convenience of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is typically plural, and one or more terminal devices 10 may be distributed within a cell managed by each access network device 20.

The access network device 20 is a device deployed in the access network to provide wireless communication functionality for the terminal device 10. The access network equipment 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. The names of access network device-capable devices may vary in systems employing different radio access technologies, for example in 5G NR systems, called gndeb or gNB. As communication technology evolves, the name "access network device" may change. For convenience of description, in the embodiment of the present application, the above-mentioned devices for providing the terminal device 10 with the wireless communication function are collectively referred to as access network devices. Alternatively, a communication relationship may be established between the terminal device 10 and the core network device 30 via the access network device 20. Illustratively, in an LTE (Long Term Evolution ) system, the access network device 20 may be EUTRAN (Evolved Universal Terrestrial Radio Access Network, evolved universal terrestrial radio network) or one or more enodebs in EUTRAN; in a 5G NR system, access network device 20 may be a RAN (Radio Access Network ) or one or more gnbs in the RAN. In the embodiment of the present application, the network device refers to the access network device 20 unless specifically described.

The core network device 30 mainly functions to provide user connection, management of users, and bearer completion of services, and to provide an interface to an external network as a bearer network. For example, core network devices in the 5G NR system may include AMF (Access and Mobility Management Function ) entities, UPF (User Plane Function, user plane function) entities, SMF (Session Management Function ) entities, and the like.

In one example, the access network device 20 and the core network device 30 communicate with each other via some air interface technology, such as an NG interface in a 5G NR system. The access network device 20 and the terminal device 10 communicate with each other via some kind of air interface technology, e.g. Uu interface.

The "5G NR system" in the embodiment of the present application may also be referred to as a 5G system or an NR system, but the meaning thereof will be understood by those skilled in the art. The technical scheme described by the embodiment of the application can be applied to a 5G NR system and also can be applied to a subsequent evolution system of the 5G NR system.

The main application scenarios of 5G NR systems include eMBB (Enhanced Mobile Broadband, enhanced mobile bandwidth), URLLC (Ultra Reliable Low Latency Communication, ultra-reliable low-latency communication) and emtc (Massive Machine Type Communication, large-scale machine-like communication).

embbs still target users to obtain multimedia content, services, and data, and their demand is growing very rapidly. On the other hand, since the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., the capability and demand of which are also relatively different, detailed analysis must be performed in connection with a specific deployment scenario, not in general. Typical applications of URLLC include industrial automation, electric automation, telemedicine operations (surgery), traffic safety assurance, etc. Typical characteristics of mctc include high connection density, small data volume, delay insensitive traffic, low cost and long life of the module, etc.

In a 5G NR network environment, for the purposes of reducing air interface signaling overhead and fast recovery of radio connections, fast recovery of data traffic, a new RRC (Radio Resource Control ) state, namely an rrc_inactive state (also referred to as an RRC INACTIVE state), is defined. This state is different from the rrc_idle state (also referred to as RRC IDLE state) and the rrc_active state (also referred to as RRC connected state).

Rrc_idle state: mobility is a UE-based cell selection reselection, paging is initiated by a CN (Core Network), and paging areas are configured by the CN. The base station side does not have a UE AS (Access Stratum) context. And, there is no RRC connection.

Rrc_connected state: there is an RRC connection and the base station and UE have a UE AS context. The network side knows that the location of the UE is cell specific. Mobility is network-side controlled mobility. Unicast data may be transmitted between the UE and the base station.

Rrc_inactive state: mobility is cell selection reselection based on UE, there is a connection between CN-NRs, UE AS context exists on a certain base station, paging is triggered by RAN, paging area based on RAN is managed by RAN, network side knows UE location is based on paging area level of RAN.

The network side may control state transition of the UE, and as shown in fig. 2, the network side may control the UE to switch among rrc_idle state, rrc_connected state, and rrc_inactive state.

In the case where the UE is in rrc_inactive state, the UE autonomously returns to rrc_idle state in several cases:

(1) When receiving the paging message initiated by the CN;

(2) When an RRC connection recovery request is initiated, starting a timer T319, and if the timer is overtime;

(3) MSG4 integrity protection fails to verify;

(4) Upon cell reselection to other RATs (Radio Access Technology );

(5) Enter a state of camping (camped on any cell) in any cell.

The rrc_inactive state includes the following features:

(1) The connection between RAN and CN is maintained;

(2) The UE and at least one base station store AS context;

(3) The UE is reachable to the RAN side, and the relevant parameters are configured by the RAN;

(4) The network side need not be notified when the UE moves within the RAN-configured RNA (RAN Notification Area ), but when the RNA is moved out;

(5) The UE moves within the RNA in accordance with the cell selection reselection mode.

When the UE is in rrc_inactive state, the network side configures configuration parameters of the rrc_inactive state for the UE through RRC Release dedicated signaling, where the main parameters include: and I-RNTI (Inactive-Radio Network Tempory Identity, inactive-radio network temporary identifier) for identifying the UE Inactive state context of the UE at the base station side and unique in the base station. The area where the RNA is used to control the UE to perform cell selection reselection in rrc_inactive state is also the paging range area for the RAN initial page. The RAN DRX cycle (RAN Discontinuous Reception cycle, RAN discontinuous reception period) is used to calculate the paging occasion for the initial paging of the RAN. RNAU periodicity (RAN Notification Area Update periodicity, RAN notification area update period) is a period for controlling the UE to perform periodic RAN location update. NCC (Network (PLMN) color Code) is used for the key used in the RRC connection recovery procedure.

The mobility behavior in the rrc_idle state, i.e. the cell selection reselection principle, is followed without informing the network side when the UE moves within the RNA region. When the UE moves out of the paging area configured by the RAN, the UE is triggered to recover the RRC connection and reacquire the paging area configured by the RAN. When downlink data arrives at the UE, the base station that maintains connection between the RAN and the CN for the UE triggers all cells in the RAN paging area to send paging messages to the UE, so that the UE in rrc_inactive state can recover RRC connection and receive data. The UE in rrc_inactive state configures a RAN paging area in which the UE needs to perform periodic location update according to a network configuration period in order to guarantee the reachability of the UE.

Therefore, the scenario that triggers the UE to perform RNA update has the RNAU timer to expire or the UE moves to an area outside the RNA.

When the target base station of the UE initiating the RRC connection recovery procedure is not an anchor (anchor) base station, the anchor base station decides whether the UE context needs to be transferred to the target base station side. Therefore, the general target base station will send the cause value carried in the UE initiated RRC connection recovery request message to the anchor base station in the UE context request process, where the anchor base station determines whether to transfer the UE context to the target base station side. For example, periodic RAN location updates typically do not require context transfer.

In the LTE system, a scheme of user plane small data transmission (i.e., EDT: early Data Transmission, advanced data transmission) is defined. In this scheme, data of the user plane is transmitted in DTCH (Dedicated Transmission Channel, dedicated transport channel) and CCCH (Common Control Channel ) MSG3 (RRCConnectionResumeRequest) message is multiplexed in MAC (Medium Access Control ) layer, so as to realize transmission of small data. The downlink may also be the multiplexing of data of the user plane in the DTCH transmission and RRCConnectionRelease message on DCCH (Dedicated Control Channel ) to transmit small data.

While packet data transmission is supported in the LTE system, packet data transmission in the LTE system is used for a specific scenario, for example, a non-networking terminal type, traffic of such terminals themselves is not large in such data amount, and packet data transmission type. So in the packet data transmission of the LTE system, data transmission of one data packet is supported.

In the NR system, there is a need to expand packet data reception in a support rrc_inactive state, and there are a plurality of packet data transmissions.

According to the technical scheme provided by the embodiment of the application, the terminal equipment can perform HARQ feedback by adopting the PUCCH resources aiming at the received small packet data by configuring the PUCCH resources for the terminal equipment for transmitting the HARQ feedback in the SDT process, so that a HARQ feedback mechanism aiming at small packet data reception is provided, and the reliability of small packet data reception is ensured. In addition, the application provides an HARQ feedback mechanism for receiving a plurality of small packet data in the RRC_INACTIVE state, thereby ensuring the reliability of the small packet data reception.

The technical scheme of the application is described and illustrated by the following examples.

Referring to fig. 3, a flowchart of an SDT-based HARQ feedback resource allocation method according to an embodiment of the present application is shown, and the method may be applied to the network architecture shown in fig. 1. The method may comprise the steps of:

in step 310, the terminal device receives configuration information, where the configuration information is used to configure PUCCH resources for sending HARQ feedback in the SDT process.

Optionally, the network device sends the configuration information to the terminal device, and accordingly, the terminal device receives the configuration information from the network device. For example, for a cell supporting SDT transmission function, the network device of the cell sends the configuration information to the terminal device in the cell.

Optionally, the configuration information is system broadcast information, such as SIB1 (System Information Block, system information block 1) message.

Alternatively, the configuration information may be used to configure one PUCCH resource group, or may also be used to configure a plurality of PUCCH resource groups. The PUCCH resource group is a resource set composed of a plurality of PUCCH resources. Multiple PUCCH resources may be included in each PUCCH resource group. In an exemplary embodiment, each PUCCH resource group includes a maximum number of PUCCH resources of 16. Of course, in some other embodiments, the maximum number may be set to other values, which embodiments of the present application do not limit.

In one example, PUCCH resources dedicated to transmitting HARQ feedback in an SDT process and PUCCH resources for other processes share the same set of configuration parameters. In this way, signalling overhead is facilitated to be saved.

In another example, PUCCH resources dedicated to transmitting HARQ feedback in the SDT process and PUCCH resources for other processes have respective independent configuration parameters. In this way, flexibility of two PUCCH resource configurations is facilitated.

Optionally, the above configuration parameters include, but are not limited to, at least one of: hoppingId, p0-nominal, pucch-GroupHopping, pucch-ResourceCommon. Wherein the hopingid is a cell-specific scrambling ID for group hopping and sequence hopping. p0-nominal is a power control parameter for PUCCH transmission. The pucch-group hopping is a configuration parameter for group hopping and sequence hopping, with a value of neither indicating that neither group hopping nor sequence hopping is enabled, with a value of enable indicating that group hopping is enabled but sequence hopping is not enabled, and with a value of disable indicating that group hopping is not enabled but sequence hopping is enabled. PUCCH resources/parameters for configuring a particular cell are PUCCH resources/parameters.

Optionally, the terminal device is in an RRC INACTIVE state, i.e. an rrc_inactive state, so as to implement an HARQ feedback mechanism for packet data reception in the case that the terminal device is in an RRC INACTIVE state, and ensure reliability of packet data reception.

In summary, according to the technical scheme provided by the embodiment of the application, by configuring the PUCCH resource for transmitting HARQ feedback in the SDT process for the terminal device, the terminal device can perform HARQ feedback by adopting the PUCCH resource for the received packet data, thereby providing an HARQ feedback mechanism for packet data reception, and ensuring the reliability of packet data reception.

Referring to fig. 4, a flowchart of an SDT-based HARQ feedback resource allocation method according to another embodiment of the present application is shown, and the method can be applied to the network architecture shown in fig. 1. The method may include the following steps (410-440):

in step 410, the terminal device receives first configuration information, where the first configuration information is used to configure one PUCCH resource group.

Optionally, the network device sends the first configuration information to the terminal device, and accordingly, the terminal device receives the first configuration information from the network device. Optionally, the first configuration information is system broadcast information, such as SIB1 message. For example, for a cell supporting the SDT transmission function, the network device of the cell sends a SIB1 message to the terminal device in the cell, where the SIB1 message includes the first configuration information.

Optionally, the first configuration information is denoted as pucch-resource common forsdt, and the configuration path of the first configuration information may be as follows:

SIB1＝＝>ServingCellConfigCommonSIB＝＝>UplinkConfigCommonSIB＝＝>BWP-UplinkCommon＝＝>pucch-ConfigCommon＝＝>pucch-ResourceCommonForSDT。

as shown below, under pucch-ConfigCommon, pucch-ResourceCommonForSDT is included:

optionally, the first configuration information pucch-ResourceCommonForSDT is only used for HARQ feedback received for SDT.

In step 420, the terminal device determines a PUCCH resource group according to a set of configuration parameters corresponding to an index value included in the first configuration information.

Optionally, the first configuration information includes an index value, the index value corresponding to a set of configuration parameters. The terminal device may store a correspondence between at least one set of index values and configuration parameters, and after acquiring the index values included in the first configuration information, the terminal device queries the correspondence to determine a set of configuration parameters corresponding to the acquired index values, and then further determines a PUCCH resource group based on the determined set of configuration parameters. Optionally, the correspondence between the at least one set of index values and the configuration parameters may be configured by a network device, or may be predefined by a protocol, which is not limited by the embodiment of the present application.

The PUCCH resource group is a resource set composed of a plurality of PUCCH resources. Multiple PUCCH resources may be included in each PUCCH resource group. In an exemplary embodiment, each PUCCH resource group includes a maximum number of PUCCH resources of 16. Of course, in some other embodiments, the maximum number may be set to other values, which embodiments of the present application do not limit.

In step 430, the terminal device receives first downlink control information, where the first downlink control information is used to indicate one PUCCH resource from the one PUCCH resource group.

Optionally, the network device sends the first downlink control information to the terminal device, and accordingly, the terminal device receives the first downlink control information from the network device. Alternatively, the first downlink control information may be DCI (Downlink Control Information ) transmitted on a PDCCH (Physical Downlink Control Channel, physical downlink control channel).

For example, one PUCCH resource group includes 16 PUCCH resources, where the sequence numbers of the 16 PUCCH resources are sequentially 0 to 15, and if the first downlink control information includes the sequence number 4, it indicates that the network device indicates to the terminal device that HARQ feedback is performed using the PUCCH resource with the sequence number 4.

In step 440, the terminal device transmits HARQ feedback received for the downlink SDT on the PUCCH resource determined by the first downlink control information.

Still further, in the above example, if the terminal device determines, based on the first downlink control information, that HARQ feedback is performed using the PUCCH resource with the sequence number 4, the terminal device sends, when there is a HARQ feedback requirement for the downlink SDT, HARQ feedback received by the downlink SDT to the network device on the PUCCH resource with the sequence number 4.

In summary, according to the technical solution provided in the embodiment of the present application, by configuring a set of PUCCH resources for transmitting HARQ feedback in the SDT process for a terminal device, and indicating one PUCCH resource for HARQ feedback received by the SDT in the set of PUCCH resources to the terminal device, when the terminal device has a HARQ feedback requirement for the downlink SDT, the terminal device performs HARQ feedback using the determined PUCCH resource, thereby providing a HARQ feedback mechanism for packet data reception, and ensuring packet data reception reliability.

Referring to fig. 5, a flowchart of an SDT-based HARQ feedback resource allocation method according to another embodiment of the present application is shown, and the method can be applied to the network architecture shown in fig. 1. The method may include the following steps (510-560):

In step 510, the terminal device receives second configuration information, where the second configuration information is used to configure a plurality of PUCCH resource groups.

Optionally, the network device sends the second configuration information to the terminal device, and accordingly, the terminal device receives the second configuration information from the network device. Optionally, the second configuration information is system broadcast information, such as SIB1 message. For example, for a cell supporting the SDT transmission function, the network device of the cell sends an SIB1 message to the terminal device in the cell, where the SIB1 message includes the second configuration information.

Optionally, the second configuration information is denoted as pucch-resource common force tlist, and the configuration path of the second configuration information may be as follows:

SIB1＝＝>ServingCellConfigCommonSIB＝＝>UplinkConfigCommonSIB＝＝>BWP-UplinkCommon＝＝>pucch-ConfigCommon＝＝>pucch-ResourceCommonForSDTList。

as shown below, under pucch-ConfigCommon, pucch-resourcecommonfortdtlist is included:

optionally, the second configuration information pucch-resourcecommenforsfiltist is only used for HARQ feedback for SDT reception.

Alternatively, maxPUCCHSDT represents the maximum number of PUCCH resource groups allocated for SDT, for example, 4. Wherein, each PUCCH resource group in PUCCH-ResourceCommonForSDTList can generate PUCCH resources for SDT reception feedback. Optionally, each PUCCH resource group includes a maximum number of PUCCH resources of 16. Of course, in some other embodiments, the maximum number may be set to other values, which embodiments of the present application do not limit.

In addition, since the second configuration information configures a plurality of PUCCH resource groups, the terminal device needs to determine which one of the plurality of PUCCH resource groups to use when selecting PUCCH resources for HARQ feedback. In this embodiment, the terminal device determines in the manner provided in steps 520-540 below.

In step 520, the terminal device determines a plurality of PUCCH resource groups according to configuration parameters respectively corresponding to the plurality of index values included in the second configuration information.

Optionally, the second configuration information includes a plurality of index values, each index value corresponding to a set of configuration parameters. The terminal equipment can store the corresponding relation between at least one group of index values and configuration parameters, after acquiring a plurality of index values contained in the second configuration information, the terminal equipment inquires the corresponding relation, determines the configuration parameters respectively corresponding to the acquired plurality of index values, and then further determines a plurality of PUCCH resource groups based on the determined plurality of groups of configuration parameters. Optionally, the correspondence between the at least one set of index values and the configuration parameters may be configured by a network device, or may be predefined by a protocol, which is not limited by the embodiment of the present application.

In step 530, the terminal device determines the first number value based on the identification information of the terminal device itself.

The identification information of the terminal device is used for playing a role of unique identification for the terminal device. Optionally, the identification information of the terminal device is any one of the following: I-RNTI, C-RNTI (Cell-Radio Network Tempory Identity, cell-radio network temporary identity). Of course, in some other embodiments, the identification information of the terminal device may also be other information with a unique identification function, which is not limited in the embodiments of the present application.

Optionally, the terminal device determines a remainder obtained by dividing the identification information of the terminal device by the number of PUCCH resource groups as the first number value.

In one example, taking the identification information as the I-RNTI as an example, it is assumed that the number of PUCCH resource groups configured by the network device through the second configuration information is M, that is, the number of configurations included in the PUCCH-resource common format list. The terminal equipment calculates I-RNTI mod M=K, wherein K is the first number value.

In another example, taking the identification information as the C-RNTI as an example, assume that the number of PUCCH resource groups configured by the network device through the second configuration information is M, that is, the number of configurations included in the PUCCH-resource common format list. The terminal equipment calculates C-RNTI mod M=K, wherein K is the first number value.

In step 540, the terminal device determines, from among the plurality of PUCCH resource groups, the PUCCH resource group having the number value of the first number value as an available PUCCH resource group for the terminal device to transmit HARQ feedback.

Optionally, the plurality of PUCCH resource groups are numbered sequentially from 0 in the order in the list. Assuming that the number of PUCCH resource groups configured in PUCCH-ResourceCommonForSDTList is M, the numbers of the M PUCCH resource groups are sequentially from 0 to M-1.

For example, the number of PUCCH resource groups configured in PUCCH-ResourceCommonForSDTList is 4, and the number values of the 4 PUCCH resource groups are 0, 1, 2, and 3 in order. Assuming that the first number value calculated in step 630 is 2, the terminal device determines the PUCCH resource group with the number value of 2 from the 4 PUCCH resource groups as an available PUCCH resource group for the terminal device to send HARQ feedback.

In step 550, the terminal device receives second downlink control information, where the second downlink control information is used to indicate one PUCCH resource from the selected one PUCCH resource group.

Optionally, the network device sends the second downlink control information to the terminal device, and accordingly, the terminal device receives the second downlink control information from the network device. Alternatively, the second downlink control information may be DCI transmitted on the PDCCH.

For example, one PUCCH resource group includes 16 PUCCH resources, where the sequence numbers of the 16 PUCCH resources are sequentially 0 to 15, and if the second downlink control information includes sequence number 8, it indicates that the network device indicates to the terminal device that HARQ feedback is performed using the PUCCH resource with sequence number 8.

In step 560, the terminal device transmits HARQ feedback received on the downlink SDT on the PUCCH resource determined by the second downlink control information.

Still further, in the above example, if the terminal device determines, based on the second downlink control information, that HARQ feedback is performed using the PUCCH resource with sequence number 8, the terminal device sends, when there is a HARQ feedback requirement for the downlink SDT, HARQ feedback for downlink SDT reception to the network device on the PUCCH resource with sequence number 8 of the PUCCH resource group with sequence number 2.

In summary, according to the technical solution provided in the embodiment of the present application, by configuring multiple groups of PUCCH resources for transmitting HARQ feedback in the SDT process for a terminal device, the terminal device may determine an available PUCCH resource group based on its own identification information, and the network device indicates, to the terminal device, one PUCCH resource for HARQ feedback received by the SDT in the PUCCH resource group, so that when there is a requirement for HARQ feedback for the downlink SDT, the terminal device performs HARQ feedback using the PUCCH resource determined in the available PUCCH resource group, thereby providing an HARQ feedback mechanism for receiving packet data, and ensuring reliability of packet data reception.

Referring to fig. 6, a flowchart of an SDT-based HARQ feedback resource allocation method according to another embodiment of the present application is shown, and the method can be applied to the network architecture shown in fig. 1. The method may include the following steps (610-640):

in step 610, the terminal device receives second configuration information, where the second configuration information is used to configure a plurality of PUCCH resource groups.

Optionally, the network device sends the second configuration information to the terminal device, and accordingly, the terminal device receives the second configuration information from the network device. The description of the second configuration information can be referred to the embodiment of fig. 5, and this embodiment will not be repeated.

In step 620, the terminal device determines a plurality of PUCCH resource groups according to configuration parameters respectively corresponding to the plurality of index values included in the second configuration information.
