Disclosure The technical solutions in the disclosure will be described below with reference to the drawings in the disclosure.

In communication systems, such as NR systems, REDCAP terminals are mainly used in large-scale machine type communication (massive machine type communication, mMTC) scenarios. Among them, the REDCAP terminal in the NR system can also be called the NR REDCAP terminal. Compared with traditional terminals (such as legacy terminals), REDCAP terminals are mainly characterized by reduced or limited terminal capabilities. Optionally, the bandwidth capability of the REDCAP terminal is limited, for example, the maximum bandwidth of a bandwidth part (bandwidth part, BWP) supported by the REDCAP terminal will be reduced to 20 megahertz (hertz, Hz). Optionally, the signal processing capability (processing capability) of the REDCAP terminal is reduced, and the signal processing delay (processing time) is increased. For example, the processing delay of a REDCAP terminal increases to two times for a legacy terminal (such as an enhanced mobile bandwidth (eMBB) terminal and/or an ultra-reliable and low latency communication (uRLLC) terminal). times. Optionally, the antenna capability of the REDCAP terminal is reduced. For example, the number of antennas supported by a legacy terminal is 2 transmit antennas and 4 receive antennas (2Tx4Rx), and the REDCAP terminal will only support 1 transmit antenna and 2 receive antennas (1Tx2Rx) or 1 transmit antenna and 1 receive antenna Antenna (1Tx1Rx). Optionally, the duplex capability of the REDCAP terminal is reduced. For example, some REDCAP terminals support half-duplex frequency division duplex (HD-FDD), but do not support full-duplex frequency division duplex (full-duplex frequency division duplex, FD-FDD).

Wherein, compared with a terminal supporting FD-FDD (which may be called an FD-FDD terminal), a terminal supporting HD-FDD (which may be called an HD-FDD terminal) cannot transmit and receive at the same time. However, in an FDD cell, since the FD-FDD terminal in the cell has the ability to transmit and receive uplink and downlink at the same time, the uplink and downlink resources configured at the cell level may overlap in time. When the uplink and downlink resources configured at the cell level overlap in time, the HD-FDD terminal needs to know whether it is a resource for sending uplink signals or a resource for receiving downlink signals at the current moment. Among them, the downlink resources configured at the cell level include resources of a synchronized signal block (SSB), common search space (common search space, CSS), etc., and the uplink resources configured at the cell level include physical random access channel opportunities (PRACH ( physical random access channel) occasion, RO), physical uplink shared channel resource unit (PUSCH (physical uplink shared channel) resource unit, PRU), etc. Wherein, RO is used for sending PRACH, and preamble can be carried on PRACH, and PRU is used for sending PUSCH, and uplink data can be carried on PUSCH. When the uplink and downlink resources configured at the cell level overlap in time, for example, when the CSS configured at the cell level overlaps with RO/PRU, the network device is not sure whether the HD-FDD terminal should send RO/PRU in the overlapping time unit, so it is If the PDCCH is sent on the CSS of the time resource, will the HD-FDD terminal detect the PDCCH on the CSS, resulting in ineffective communication between the network device and the HD-FDD terminal. In order to enable the HD-FDD terminal to know whether it is a resource for sending an uplink signal or a resource for receiving a downlink signal at the current moment, and realize communication effectively, the present disclosure provides corresponding methods and devices.

For example, when the downlink signal configured at the cell level conflicts with the time domain position of the uplink signal configured at the cell level, in one implementation, the cell configures priorities for each channel, so that the HD-FDD terminal, according to the priorities configured by the cell, Send or receive on a higher priority channel. However, when the RO period is the same as the SSB (or CSS) period, it causes each RO to conflict with the SSB (or CSS). Assuming that the priority of the RO configuration is low, this implementation will cause all ROs to be unable to send PRACH, thus causing the problem that there is no available RO/PRU in case of conflict. In another implementation, the cell does not configure priority for each channel, but the HD-FDD terminal determines the period for sending uplink signals or receiving downlink signals by itself. In this implementation, when RO (or PRU) and SSB ( or CSS) conflict, the network device is not sure if the PDCCH is sent on the CSS of the time resource, whether the HD-FDD terminal will detect the PDCCH on the CSS, resulting in ineffective communication between the network and the HD-FDD terminal. Therefore, in an FDD cell, when the common downlink resource SSB/CSS of the cell conflicts with the common uplink resource RO/PRU of the cell in time, how the HD-FDD UE determines the sending direction/receiving direction is still a problem to be solved.

In order to solve the problem in the first aspect above, the present disclosure provides a resource configuration method. In the resource configuration method, the terminal device determines in which time units to receive downlink data and in which time units to send uplink data according to the direction indication information received from the network device. The data is beneficial for the network device and the terminal device to agree on whether to detect the downlink control identifier DCI in the common search space CSS.

For another example, since the RO and the PRU are periodic resources configured by the network device, the RO and the PRU may conflict with other configurations and cause the resource to be an invalid resource (invalid). Therefore, the existing standard protocol specifies a method for judging the validity of ROs and PRUs, which is used to judge which ROs/PRUs are valid (valid ROs/PRUs) in each configuration cycle. In an FDD cell, for HD-FDD terminal equipment, if the RO and PRU validity judgment method and sorting rules of the TDD cell are followed, that is, ROs that conflict with SSB or downlink symbols cannot be used as valid ROs, a RO mapping cycle may occur In the case where the number of failed ROs is inconsistent with the number of PRUs, the RO/PRU mapping rules of the HD-FDD terminal equipment and the FD-FDD terminal equipment in the cell are inconsistent. This may cause the network device to fail to determine a suitable receiving filter when receiving a specific RO or PRU, which affects the receiving performance.

In order to solve the above problems, the present disclosure provides another resource configuration method. In the resource configuration method, the HD-FDD terminal equipment adopts the RO/PRU validity judgment rules and sorting rules of the FD-FDD terminal equipment to avoid HD-FDD The RO/PRU mapping rules of the uplink resources of the terminal equipment and the FD-FDD terminal equipment are different, which leads to confusion of network equipment identification and degradation of reception performance.

The resource configuration method provided in the present disclosure can be applied to the communication system shown in FIG. 1 , where the communication system includes network devices and terminal devices. It can be understood that FIG. 1 is only an example, and the communication system may include one or more network devices, and may also include one or more terminal devices, which is not limited in this embodiment.

(1) Protocol layer structure

Communication between network devices and terminal devices follows a certain protocol layer structure. The protocol layer structure may include a control plane protocol layer structure and a user plane protocol layer structure. For example, the control plane protocol layer structure may include a radio resource control (radio resource control, RRC) layer, a packet data convergence protocol (packet data convergence protocol, PDCP) layer, a radio link control (radio link control, RLC) layer, a media The access control (media access control, MAC) layer and the function of the protocol layer such as the physical layer. For example, the user plane protocol layer structure may include the functions of the PDCP layer, the RLC layer, the MAC layer, and the physical layer. In a possible implementation, the PDCP layer may also include a service data adaptation protocol (service data adaptation protocol). protocol, SDAP) layer.

Taking data transmission between network devices and terminal devices as an example, data transmission needs to go through user plane protocol layers, such as SDAP layer, PDCP layer, RLC layer, MAC layer, and physical layer. Wherein, the SDAP layer, the PDCP layer, the RLC layer, the MAC layer and the physical layer may also be collectively referred to as an access layer. According to the transmission direction of the data, it is divided into sending or receiving, and each layer above is divided into a sending part and a receiving part. Taking downlink data transmission as an example, after the PDCP layer obtains data from the upper layer, it transmits the data to the RLC layer and the MAC layer, and then the MAC layer generates transmission blocks, and then wirelessly transmits them through the physical layer. Data is encapsulated correspondingly in each layer. For example, the data received by a certain layer from the upper layer of this layer is regarded as the service data unit (service data unit, SDU) of this layer, and after being encapsulated by this layer, it becomes a protocol data unit (protocol data unit, PDU), and then passed to next layer.

Exemplarily, the terminal device may also have an application layer and a non-access layer. Among them, the application layer can be used to provide services to the application program installed in the terminal device. For example, the downlink data received by the terminal device can be transmitted to the application layer in turn by the physical layer, and then provided to the application program by the application layer; The application layer can obtain the data generated by the application program, and transmit the data to the physical layer in turn, and send it to other communication devices. The non-access layer can be used to forward user data, such as forwarding uplink data received from the application layer to the SDAP layer or forwarding downlink data received from the SDAP layer to the application layer.

Network devices may include CUs and DUs. Multiple DUs can be centrally controlled by one CU. As an example, the interface between the CU and the DU may be referred to as an F1 interface. Wherein, the control plane (control panel, CP) interface may be F1-C, and the user plane (user panel, UP) interface may be F1-U. CU and DU can be divided according to the protocol layer of the wireless network: for example, the functions of the PDCP layer and above protocol layers are set in the CU, and the functions of the protocol layers below the PDCP layer (such as RLC layer and MAC layer, etc.) are set in the DU; another example, PDCP The functions of the protocol layer above the layer are set in the CU, and the functions of the protocol layer below the PDCP layer are set in the DU.

It can be understood that the above division of the processing functions of CU and DU according to the protocol layer is only an example, and it can also be divided in other ways, for example, the CU or DU can be divided into functions with more protocol layers, and For example, the CU or DU can also be divided into some processing functions with the protocol layer. In one design, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the rest of the functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU. In another design, the functions of the CU or DU can also be divided according to the business type or other system requirements, for example, according to the delay, and the functions whose processing time needs to meet the delay requirement are set in the DU, which does not need to meet the delay The required feature set is in the CU. In another design, the CU may also have one or more functions of the core network. Exemplarily, the CU can be set on the network side to facilitate centralized management. In another design, the wireless unit (radio unit, RU) of the DU is set remotely. Wherein, the RU has a radio frequency function.

Optionally, DUs and RUs can be divided in a physical layer (physical layer, PHY). For example, the DU can implement high-level functions in the PHY layer, and the RU can implement low-level functions in the PHY layer. Among them, when used for transmission, the functions of the PHY layer may include adding a cyclic redundancy check (cyclic redundancy check, CRC) code, channel coding, rate matching, scrambling, modulation, layer mapping, precoding, resource mapping, physical antenna mapping, and/or RF routing capabilities. For reception, the functions of the PHY layer may include CRC, channel decoding, de-rate matching, descrambling, demodulation, de-layer mapping, channel detection, resource de-mapping, physical antenna de-mapping, and/or radio frequency receiving functions. Wherein, the high-level functions in the PHY layer may include a part of the functions of the PHY layer, for example, this part of the functions is closer to the MAC layer, and the lower-level functions in the PHY layer may include another part of the functions of the PHY layer, for example, this part of the functions is closer to the radio frequency function. For example, high-level functions in the PHY layer may include adding CRC codes, channel coding, rate matching, scrambling, modulation, and layer mapping, and low-level functions in the PHY layer may include precoding, resource mapping, physical antenna mapping, and radio transmission functions; alternatively, high-level functions in the PHY layer may include adding CRC codes, channel coding, rate matching, scrambling, modulation, layer mapping, and precoding, and low-level functions in the PHY layer may include resource mapping, physical antenna mapping, and radio frequency send function.

Exemplarily, the function of the CU may be implemented by one entity, or may also be implemented by different entities. For example, the functions of the CU can be further divided, and the control plane and the user plane are separated and implemented by different entities, which are the control plane CU entity (CU-CP entity) and the user plane CU entity (CU-UP entity). The CU-CP entity and the CU-UP entity can be coupled with the DU to jointly complete the functions of the RAN equipment.

In the above architecture, the signaling generated by the CU can be sent to the terminal device through the DU, or the signaling generated by the terminal device can be sent to the CU through the DU. For example, signaling at the RRC or PDCP layer will eventually be processed as signaling at the physical layer and sent to the terminal device, or converted from received signaling at the physical layer. Under this architecture, the signaling at the RRC or PDCP layer can be considered to be sent through DUs, or sent through DUs and RUs.

Optionally, any one of the foregoing DU, CU, CU-CP, CU-UP, and RU may be a software module, a hardware structure, or a software module+hardware structure, without limitation. Wherein, the existence forms of different entities may be different, which is not limited. For example, DU, CU, CU-CP, and CU-UP are software modules, and RU is a hardware structure. These modules and the methods performed by them are also within the protection scope of the present disclosure.

For ease of understanding, the definitions of related terms involved in the present disclosure are introduced in detail below.

Synchronization signal block SSB: The terminal device detects a synchronization signal block (SSB) when performing cell search. The synchronization signal block SSB includes a primary synchronization signal (primary synchronized signal, PSS) and a secondary synchronization signal (secondary synchronized signal, SSS), and a physical broadcast channel (physical broadcast channel, PBCH). Wherein, the time domain position of the SSB varies according to the frequency band where the cell carrier is located and the subcarrier spacing of the SSB. The existing protocol stipulates that multiple SSBs form an SSB burst (SSBBurst), and the duration of one SSB Burst is 5 milliseconds (ms). The wireless access network device can send SSB in the way of spatial beam scanning, and scan to complete an SSB Burst within 5ms. The number of SSBs in SSB Burst is called SSB Burst size. For the Sub3GHz frequency band, the maximum value of SSB Burstsize is 4; for the Sub3GHz～Sub6GHz frequency band, the maximum value of SSB Burstsize is 8; for frequencies greater than 6GHz, the maximum value of SSB Burstsize is 64. Wherein, the radio access network device configures the SSB Burst cycle for the terminal device, for example, configures the SSB Burst cycle as 5ms, 10ms, 20ms, 40ms, 80ms and 160ms. After the terminal device configures the period of SSB Burst (for example, 20ms), the terminal device searches for a maximum of 8 periods on one frequency point, and if the SSB is not found, it searches for another frequency point.

A possible time domain arrangement of SSB is shown in Fig. 2 . In Figure 2, the period of SSB Burst is defined as 20ms, and the size of SSB Burst is 8. SSB Burst sends SSB in the first half frame of one frame in a period of 5ms. A total of 8 SSBs are sent every 5ms, which can correspond to 8 different beams. direction. Wherein, the length of each frame is 10ms, including the first half frame of 5ms and the second half frame of 5ms. When the terminal device does not obtain the downlink synchronization signal or loses the downlink synchronization signal, it will not be able to determine the time domain position of the SSB, so it needs to blindly detect the synchronization signal in the SSB at each time symbol. For example, a terminal device may search for a synchronization signal on each symbol within a cycle (20ms) shown in FIG. 2 until PSS and SSS are obtained.

Common search space CSS: The network device can configure the CSS for the terminal device through the signaling PDCCH-ConfigCommon in the SIB. Optionally, PDCCH-ConfigCommon specifically includes the following parameters: searchSpaceSIB1, used to indicate PDCCH resources, and the PDCCH carries DCI for scheduling SIB1; searchSpaceOtherSystemInformation, used to indicate PDCCH resources, and the PDCCH is used for scheduling SIB1 DCI of other system information; pagingSearchSpace, used to indicate the resource of PDCCH, the PDCCH carries the DCI used for scheduling paging; ra-SearchSpace, used to indicate the resource of PDCCH, the PDCCH is used to carry the PDCCH in the random access process DCI sent by the terminal.

Physical Random Access Channel Opportunity RO: The time domain resource of RO is configured through RACH-ConfigGeneric signaling. Specifically, the prach-ConfigurationIndex signaling is used to look up the table (the table to be queried is Table 6.3.3.2-2-6.3.3.2-4 in the standard protocol 38.211). For example, the prach-ConfigurationIndex signaling indicates a row in Table 6.3.3.2-2 to 6.3.3.2-4 in the standard protocol 38.211, and each row in the table indicates the preamble format (preamble format), RO configuration cycle length (in system frame number), the subframe number of the RO included in each RO configuration cycle, the start symbol, the number of slots of the RO included in each subframe, and the like. For example, taking the PRACH configuration in line 27 of Table 6.3.3.2-2 in the standard protocol 38.211 as an example, the length of the RO configuration cycle is the length of 1 frame (10ms), and each cycle (that is, each frame ) in the 1st to 10th subframes (subframes) in which ROs are configured, and the time-domain start symbol of ROs in the subframes in which ROs are configured is the first symbol. For the preamble of preamble format 0, the time domain length occupied by one RO is the length of one subframe, that is to say, all the symbols in the subframe configured with RO are time domain resources of RO. Wherein, when the terminal device performs four-step random access (4-step RACH) or two-step random access (2-step RACH), it sends a preamble (preamble) to the network device on the RO.

Physical uplink shared channel resource unit PRU: The meaning of PRU is a combination of a physical uplink shared channel opportunity (PUSCHoccasion) and a demodulation reference signal (de-modulation reference signal, DMRS). The time domain resources of the PRU can be understood as the time domain resources of the PUSCH occasion. Configure the PUSCH occasion resource through the MsgA-PUSCH-Resource signaling. MsgA-PUSCH-Resource specifically includes the following parameters: msgA-PUSCH-TimeDomainOffset, which indicates the combination of the time domain start resource, symbol length and PUSCH mapping type in the PUSCH-TimeDomainResourceAllocation table, so that the PUSCH occasion can be indicated by msgA-PUSCH-TimeDomainOffset The slot offset number of the time domain start resource relative to the PRACH slot start resource. nrofMsgA-PO-PerSlot indicates the number of occasions of the time-domain PUSCH in each slot. Wherein, the PUSCH opportunities including the protection period are continuous in the time domain within one slot, so that nrofMsgA-PO-PerSlot can indicate the number of PUSCH time domains in each slot. nrofMsgA-PO-FDM indicates the number of msgA PUSCH opportunities for frequency division multiplexing in one instance, so that the number of PUSCH frequency domains can be indicated by nrofMsgA-PO-FDM.

Mapping relationship between ROs and PRUs: FIG. 3 is a schematic diagram of a mapping relationship between ROs and PRUs provided in the present disclosure. Among them, it is assumed that in each RO mapping period, there are 4 ROs in the time domain, 2 ROs in the frequency domain, and 8 ROs in one RO mapping period (the SSBs are all mapped to one RO mapping period, for example, the There are 4 SSBs in one SSB Burst, and each SSB in the network configuration maps 2 ROs, so there are 8 ROs in one RO mapping cycle). Wherein, each RO in an RO mapping cycle is configured with 4 preamble indexes (index), then there are 32 preamble indexes in the RO mapping cycle, as shown in FIG. 3 . Wherein, the index in Figure 3 PUSCH occasion refers to the index of the preamble corresponding to the DMRS (PRU) in the PUSCH. For example, the index 0-1 in the first PUSCH occasion shown in Figure 3 refers to the index 0-1 of DMRS-1 in the PUSCH corresponding to the preamble in the first RO, and the index 8-9 refers to the index 0-1 in the PUSCH DMRS-2 corresponds to the index 8-9 of the preamble in the third RO. If the network device configures 16 PRU resources in the RO mapping cycle, then every two preambles correspond to one PRU, and the mapping relationship between RO and PRU is shown in Figure 3 . Among them, when the terminal device selects the preamble with the specified number to send the PRACH, the terminal device also needs to select the PRU at the corresponding position to send the PUSCH, which together form the message A (MsgA) in the 2-step RACH.

Correspondence between RO and SSB: When a terminal device initiates random access (such as four-step random access), the terminal device needs to measure SSB first when selecting RO, and select a reference signal received power (RSRP) The SSB index is higher than the set threshold, and an RO is selected according to the corresponding relationship between the SSB index and the RO configured in the network. This is beneficial for the network device to adopt a suitable receiving filter to receive a specific RO. For example, the network device configures a certain RO to correspond to SSB1. When the terminal device measures that the RSRP of SSB1 is higher than the threshold, the terminal device selects this RO to send a preamble, and the network device uses the receiving filter corresponding to SSB1 to receive the terminal device on the RO. The sent preamble is beneficial to improve the receiving performance.

Fig. 4 is a schematic flowchart of the first resource allocation method provided by the present disclosure. Wherein, the resource configuration method is implemented by the interaction between the terminal device and the network device. It should be noted that the terminal equipment interacting with the network equipment in this disclosure is a half-duplex frequency division duplex HD-FDD terminal. The resource configuration method includes the following steps:

401. The network device sends first configuration information and direction indication information to the terminal device; correspondingly, the terminal device receives the first configuration information and direction indication information from the network device.

Wherein, the first configuration information is used to configure time resources of the RO and/or the PRU. Optionally, the first configuration information is also used to configure time domain resources of the SSB and/or CSS. For example, a network device (FDD cell) configures time resources of cell-level uplink and downlink resources such as RO, PRU, SSB, and CSS in a system message, and broadcasts the system message to terminal devices in the cell.

Wherein, the direction indication information is used to indicate time domain resources for the terminal device to send uplink data and/or time domain resources for the terminal device to receive downlink data in the first period. Wherein, the time-domain resource used for the terminal device to send uplink resources includes one or more second periods, the time-domain resource used for the terminal device to receive downlink data includes one or more second periods, and the length of the second period is one or more Multiple RO cycle lengths. That is, the second cycle is defined as one or more RO cycles. Optionally, the second period is defined as one or more RO mapping periods. Wherein, one RO mapping cycle may include multiple RO cycles, so as to ensure that each SSB is mapped to. Wherein, according to the description in FIG. 3 , there is a mapping relationship between RO and PRU, and one PRU mapping cycle is one RO mapping cycle. Optionally, the length of the first cycle is the length of N second cycles, the first cycle is defined to include multiple second cycles, and each second cycle includes one or more RO cycles or RO mapping cycles. Wherein, N is an integer greater than or equal to 1.

For example, FIG. 5 is a schematic diagram of an RO cycle and an RO mapping cycle provided in the present disclosure. Wherein, the length of one RO cycle configured by the network device is 2 frames, and the length of each frame is 10 milliseconds (ms), so the length of one RO cycle is 20 ms. Each RO period includes 1 RO for time division multiplexing and 2 ROs for frequency division multiplexing. If the cell has 4 SSBs, and the network device configures that each SSB corresponds to 1 RO, then one RO mapping period includes 2 RO periods (4 frames). In the 2-step RACH scenario, the network device is also configured with MsgA PUSCH resources, and the PRU mapping period is the same as the RO mapping period, which is also 4 frames. It can be seen that by configuring the direction indication information, the network device can specify that each RO cycle (or RO mapping cycle) is used for the terminal device to send uplink data or receive downlink data, and the network device indicates to the terminal device which RO cycle (or RO mapping periods) to send uplink data, and in which RO periods (or RO mapping periods) to receive downlink data.

In an implementation manner, the network device indicates the time domain resource used for the terminal device to send uplink data and/or the time domain used for the terminal device to receive downlink data in the first period by explicitly configuring radio resource control (radioresourcecontrol, RRC) signaling. Domain resources. Among them, the network device sends RRC signaling to the terminal device, and the RRC signaling is used to indicate that: the second cycle from the Kth to the K+Mth in the first cycle is used for the terminal device to send uplink data, and the first cycle except the first cycle The second periods other than the K to K+M second periods are used for the terminal equipment to receive the downlink data; or, the Kth to K+M second periods in the first period are used for the terminal equipment to receive the downlink data data, and the second cycle except the Kth to K+M second cycle in the first cycle is used for terminal equipment to send uplink data, K and M are both integers greater than or equal to 1, and K+M ≤N.

For example, the network device explicitly configures the length of the first cycle as 4 second cycles through RRC signaling. In addition, K=2 and M=2 are configured, so that in the second to fourth second cycles in a first cycle, the terminal device receives downlink data, and in the first second cycle, the terminal device sends uplink data.

Optionally, the RRC signaling only instructs the terminal device to perform a behavior (for example, the terminal device receives downlink data) in the second period, and does not indicate the behavior of the terminal device in other periods. That is to say, the RRC signaling is used to indicate: the second cycle from the Kth to K+M in the first cycle is used for the terminal equipment to send uplink data, and the Kth to K+Mth in the first cycle The second period other than the two periods is used for the terminal device to determine to receive downlink data or send uplink data. Alternatively, the Kth to K+M second periods in the first period are used for the terminal equipment to receive downlink data, and the second periods in the first period except the Kth to K+M second periods It is used for the terminal device to determine to send uplink data or receive downlink data; wherein, K and M are both integers greater than or equal to 1, and K+M≤N.

For example, the network device explicitly configures the length of the first cycle as 4 second cycles through RRC signaling. And, configure K=2, M=2, so that in the second to fourth second cycles in a first cycle, the terminal device receives downlink data, and in the first second cycle, the terminal device determines to send uplink data by itself Or receive downlink data.

In an implementation manner, the network device indicates the time domain resource for the terminal device to send uplink data and/or the time domain resource for the terminal device to receive downlink data in the first period by configuring a bitmap. Wherein, the bitmap configured by the network device includes N bits, and the N bits are in one-to-one correspondence with the N second periods. A specific indication manner of the network device through the bitmap is: the network device sends the bitmap to the terminal device, and the bitmap includes N bits. For each of the N bits, the value of the bit is 0 or 1, the bit value is 0 to indicate that the second cycle corresponding to the bit is used for the terminal device to send uplink data, and the bit value is 1 to indicate that the bit corresponds to The second period of is used for terminal equipment to receive downlink data. Or, for each of the N bits, the bit value is 0 or 1, the bit value is 0 to indicate that the second cycle corresponding to the bit is used for the terminal device to receive downlink data, and the bit value is 1 to indicate the The second period corresponding to the bit is used for the terminal device to send uplink data.

For example, the network device configuration bitmap includes 10 bits, and the length of the first cycle is 10 second cycles. Among them, assuming that there are 4 bits with a bit value of 0, and 6 bits with a bit value of 1, the bit value of 0 is used to indicate that the 4 second periods corresponding to the 4 bits are used for the terminal device to send uplink data, and the bit value is 0. A value of 1 is used to indicate that 6 second periods corresponding to 6 bits are used for the terminal device to receive downlink data. Or, a bit value of 0 is used to indicate that 4 second periods corresponding to 4 bits are used for the terminal device to receive downlink data, and a bit value of 1 is used to indicate that 6 second periods corresponding to 6 bits are used for the terminal device to send uplink data data.

Optionally, the network device only instructs the terminal device to perform a second period of a behavior (for example, the terminal device receives downlink data) through the bitmap, and does not indicate behaviors of the terminal device in other periods. That is to say, the specific indication manner of the network device through the bitmap is: the network device sends the bitmap to the terminal device, and the bitmap includes N bits. For each of the N bits, the value of the bit is 0 or 1, the bit value is 0 to indicate that the second cycle corresponding to the bit is used for the terminal device to send uplink data, and the bit value is 1 to indicate that the bit corresponds to The second period of is used for the terminal device to determine to receive downlink data or send uplink data. Or, for each of the N bits, the bit value is 0 or 1, the bit value is 0 to indicate that the second cycle corresponding to the bit is used for the terminal device to receive downlink data, and the bit value is 1 to indicate the The second period corresponding to the bit is used for the terminal device to determine to send uplink data or receive downlink data.

In an implementation manner, the network device indicates the time domain resource used for the terminal device to send uplink data and/or the time domain resource used for the terminal device to receive downlink data in the first period by configuring a mask (mask). Wherein, one mask is used to indicate that the masked second cycle in the first cycle is used to receive downlink data, and the second cycle not masked in the first cycle is used to send uplink data. Specifically, the network device configuration first period includes N second periods, where N is an integer greater than or equal to 1. The network device sends a mask index value (mask index) to the terminal device, and the mask index value is used to indicate: the odd-numbered second cycle in the first cycle is used for the terminal device to receive downlink data, and the even-numbered second cycle in the first cycle The second period is used for terminal equipment to send uplink data. Alternatively, the even-numbered second period in the first period is used for the terminal device to receive downlink data, and the odd-numbered second period in the first period is used for the terminal device to send uplink data. Alternatively, the 1st to Mth second periods in the first period are used for terminal equipment to receive downlink data, and the M+1th to Nth second periods in the first period are used for terminal equipment to send uplink data, and M is An integer greater than or equal to 1, and M≤N. Alternatively, the Kth to K+M second periods in the first period are used for the terminal equipment to receive downlink data, and the second periods in the first period except the Kth to K+M second periods For terminal equipment to send uplink data, both K and M are integers greater than or equal to 1, and K+M≤N. Among them, values such as M and K are indicated by the network device in the system information and broadcast to the terminal device.

For example, Table 1 is a mask table provided in the present disclosure, and the mask table includes mask index values and mask information corresponding to the mask index values.

Table 1: A mask table

掩码索引值mask index value	掩码信息mask information
00	第一周期中的第奇数个第二周期用于接收下行数据The odd-numbered second cycle in the first cycle is used to receive downlink data
11	第一周期中的第偶数个第二周期用于接收下行数据The even-numbered second period in the first period is used to receive downlink data
22	第一周期中的前M个第二周期用于接收下行数据The first M second periods in the first period are used to receive downlink data
33	第一周期中的第K个至第K+M个第二周期用于接收下行数据The K-th to K+M second cycles in the first cycle are used to receive downlink data
……	……

Wherein, according to Table 1, when the terminal device receives a mask index value of 0, the terminal device determines to receive downlink data in the odd-numbered second cycle in the first cycle, and to send uplink data in the even-numbered second cycle. When the terminal device receives a mask index value of 1, the terminal device determines to receive downlink data in the even-numbered second cycle in the first cycle, and to send uplink data in the odd-numbered second cycle.

In an implementation manner, the direction indication information is also used to indicate flexible resources, and the flexible resources are used to receive downlink channels or send uplink channels. Wherein, the flexible resource includes an effective flexible symbol (flexible, F symbol). For example, in an FDD cell, the network device may also send signaling tdd-UL-DL-ConfigurationCommon to the HD-FDD terminal. Wherein, the tdd-UL-DL-ConfigurationCommon signaling is used to instruct the terminal device to send the PRACH on the effective uplink symbol (U symbol) or the effective flexible symbol (F symbol) on the RO, and send the PUSCH on the PRU.

After configuring the first configuration information and direction indication information, the network device sends the first configuration information and direction indication information to the terminal device. A specific implementation manner may be, for example, that the network device carries the first configuration information and direction indication information in the system message, and broadcasts the system message to terminals in the cell.

402. The terminal device determines one or more second periods for sending a physical random access channel and/or a physical uplink shared channel from the first period according to the direction indication information.

Wherein, after receiving the first configuration information and the direction indication information, the terminal device may determine available uplink resources (RO and/or PRU) or downlink resources (SSB and/or CSS) according to the first configuration information. Wherein, the uplink resource RO is used for sending the physical random access channel PRACH, and the uplink resource PRU is used for sending the physical uplink shared channel PUSCH. Further, the terminal device determines time domain resources (one or more second periods including one or more RO periods or RO mapping periods) for sending uplink data from the first period according to the direction indication information. After the terminal device determines the time domain resources used to send uplink data, it may determine that the time domain resources not used to send uplink data in the first period indicated by the direction indication information are the time domain resources used to send downlink data (also one or multiple second cycles). Optionally, the terminal device determines the second cycle for sending PRACH and/or PUSCH from the first cycle according to the direction indication information, and the other second cycles in the first cycle are determined by the terminal device for sending uplink data or Receive downlink data. Wherein, the specific manner of determining the terminal device varies according to the type of direction indication information sent by the network device. For example, when the network device sends RRC signaling to the terminal device, the terminal device determines the first cycle according to the Kth to K+M second cycles in the first cycle indicated by the RRC signaling for the terminal device to send uplink data The Kth to K+M second periods are used to send the PRACH and/or PUSCH. For a specific implementation manner, refer to the corresponding description in the foregoing embodiments, and details are not repeated here.

It can be seen that the present disclosure provides a resource configuration method, in which the terminal device determines in which time units to receive downlink data and in which time units to send uplink data according to the direction indication information received from the network device, which is beneficial to network devices and terminal devices The judgment on whether to detect DCI in CSS is consistent.

Fig. 6 is a schematic flowchart of a second resource configuration method provided by the present disclosure. Wherein, the resource configuration method is implemented by the interaction between the terminal device and the network device. It should be noted that the terminal device interacting with the network device in the present disclosure is a half-duplex frequency division duplex HD-FDD terminal. The resource configuration method includes the following steps:

601. The network device sends first configuration information and direction indication information to the terminal device; correspondingly, the terminal device receives the first configuration information and direction indication information from the network device.

Wherein, the first configuration information is used to configure the RO and/or the PRU, and the first configuration information is applicable to the first type terminal and the second type terminal. Optionally, the first configuration information is also used to configure time-domain resources of the SSB and/or CSS. For a specific configuration method, reference may be made to the corresponding description in the embodiment in FIG. 4 , and details are not repeated here. Wherein, the uplink and downlink resources configured by the first configuration information are applicable to the first type terminal and the second type terminal. The first type of terminal in the present disclosure is an HD-FDD terminal, and the second type of terminal is an FD-FDD terminal. That is to say, the disclosure defines that the uplink and downlink resources used by HD-FDD terminals are the same as the uplink and downlink resources used by FD-FDD terminals in the cell, and the uplink and downlink resources configured by network equipment for HD-FDD terminals and FD-FDD terminals The resources are the same, which is beneficial for network equipment to receive and process uplink data from different types of terminal equipment.

Wherein, the direction indication information is used to indicate time domain resources for sending uplink data and/or time domain resources for receiving downlink data, and the direction indication information is applicable to the first type of terminal. That is to say, the direction indication information configured by the network device is used to indicate to the HD-FDD terminal the time domain resources for sending uplink data and/or the time domain resources for receiving downlink data. For example, the direction indication information is used to indicate to the HD-FDD terminal the time domain position of the RO that sends the PRACH, and/or is used to indicate to the HD-FDD terminal the time domain position of the PRU that sends the PUSCH.

In an implementation manner, the direction indication information is specifically used to indicate time domain resources used for sending uplink data and/or time domain resources used for receiving downlink data in the first period. Wherein, the time domain resource used to send uplink data includes one or more second periods, the time domain resource used to receive downlink data includes one or more second periods, and the length of the second period is one or more RO periods length. That is, the second cycle is defined as one or more RO cycles. Optionally, the second period is defined as one or more RO mapping periods. For specific descriptions of the first cycle, the second cycle, the RO cycle, and the RO mapping cycle, refer to the corresponding description in the method in FIG. 4 , and details are not repeated here.

In an implementation manner, the network device indicates the time domain resources used for sending uplink data and/or the time domain resources used for receiving downlink data in the first period by explicitly configuring RRC signaling. For the specific implementation manner, refer to the description of the network device sending the RRC signaling to the terminal device and the specific content indicated by the RRC signaling in the method in FIG. 4 , which will not be repeated here.

In an implementation manner, the network device indicates the time domain resource used for sending uplink data and/or the time domain resource used for receiving downlink data in the first period by configuring a bitmap. For a specific implementation manner, refer to the description of the bitmap sent by the network device to the terminal device and the specific content indicated by the bitmap in the method in FIG. 4 , which will not be repeated here.

In an implementation manner, the network device indicates the time domain resource used for sending uplink data and/or the time domain resource used for receiving downlink data in the first period by configuring a mask. For the specific implementation manner, refer to the description of the network device sending the mask index value to the terminal device and the specific content of the mask index value used for indication in the method in FIG.

In an implementation manner, the direction indication information is also used to indicate flexible resources, and the flexible resources are used to receive downlink channels or send uplink channels. For the specific implementation manner, refer to the description of the flexible resources in the method in FIG. 4 , which will not be repeated here.

602. The terminal device determines resources for sending a physical random access channel and/or a physical uplink shared channel by a terminal of the first type according to the direction indication information and the first configuration information.

Wherein, after receiving the first configuration information and direction indication information, the HD-FDD terminal can determine available uplink resources (RO and/or PRU) or downlink resources (SSB and/or CSS) according to the first configuration information. Wherein, the uplink resource RO is used for sending the physical random access channel PRACH, and the uplink resource PRU is used for sending the physical uplink shared channel PUSCH. For a specific implementation manner, refer to the corresponding description in step 403 in the embodiment in FIG. 4 , and details are not repeated here.

It can be seen that the present disclosure provides a resource configuration method. In this method, the HD-FDD terminal determines that when the HD-FDD terminal and the FD-FDD terminal use the same time domain resource, the specified The downlink data is received or the uplink data is sent in the time domain resource, so that the network device and the terminal device have the same judgment on whether to detect the DCI in the CSS.

It can be understood that the resource configuration method provided by the embodiment shown in FIG. 4 and the embodiment shown in FIG. 6 is used to solve the problem that in an FDD cell, when the common downlink resource SSB/CSS of the cell and the common uplink resource RO/PRU of the cell are different from each other in time How does the HD-FDD UE determine the sending direction/receiving direction when there is an upper conflict.

FIG. 7 is a schematic flowchart of a third resource configuration method provided by the present disclosure. Wherein, the resource configuration method is implemented by the interaction between the terminal device and the network device. It should be noted that the terminal device interacting with the network device in the present disclosure is a half-duplex frequency division duplex HD-FDD terminal. The resource configuration method provided by the present disclosure is applied in a 4-step RACH scenario. The resource configuration method includes the following steps:

701. The network device sends a first downlink signal to the terminal device; correspondingly, the terminal device receives the first downlink signal from the network device.

Wherein, the first downlink signal includes the SSB in the random access scenario, the system information of the cell in the initial access scenario, and the like. Wherein, the system information of the cell in the initial access scenario includes a master information block (master information block, MIB) and a system information block (system information block, SIB). Terminal equipment can obtain CSS from SIB. Wherein, in the random access scenario, the network device broadcasts the SSB to the terminal device in the FDD cell, and correspondingly, the terminal device receives the SSB.

702. The terminal device determines the first uplink resource corresponding to the first downlink signal from the N1 candidate uplink resources.

Since the uplink resources (for example, 4-step RACH scenario includes RO) are periodic resources configured through cell-level RRC signaling, the uplink resources may conflict with other configurations, resulting in some uplink resources being invalid resources. Therefore, the present disclosure provides a method for judging the validity of uplink resources, which is used for judging which uplink resources are valid. In one implementation, the present disclosure provides an uplink resource validity judgment rule for a second type of terminal, which specifically includes: in an FDD cell, all N2 uplink resources are valid resources; or, in a TDD cell, N2 Among the uplink resources, the uplink resources that do not conflict with the downlink signal in time are effective resources. Alternatively, in a TDD cell, the candidate uplink resources included in the flexible resources are all effective resources. Wherein, the second type of terminal is an FD-FDD terminal, and the HD-FDD terminal is judged by the validity judgment rule of the FD-FDD terminal.

It should be noted that the embodiment in FIG. 7 mainly involves the 4-step RACH scenario, and the validity judgment of the cell-level uplink resource can be regarded as the validity judgment of the RO. For example, in an FDD cell, all ROs are valid. In a TDD cell, when the network device is not configured with direction indication information (for example, tdd-UL-DL-ConfigurationCommon is not configured), all ROs that do not conflict with the SSB in time are valid. In a TDD cell, when the network device is configured with direction indication information (for example, tdd-UL-DL-ConfigurationCommon is configured), all ROs in the U symbol are valid. Alternatively, the ROs in the F symbol after at least N _gap symbols of the previous downlink symbol (D symbol) are valid. Alternatively, ROs in F symbols after at least N _gap symbols of the previous SSB are valid. Wherein, the value of N _gap is specified by a protocol or configured by a network device.

Wherein, the terminal device determines N1 candidate uplink resources from the N2 uplink resources according to the validity judgment rule for the second type of terminal, and the N1 candidate uplink resources are all valid uplink resources. After valid uplink resources are determined, the terminal device may also sort the valid uplink resources. In one implementation manner, the present disclosure provides a sorting rule for the second type of terminal, which specifically includes: sorting the N1 candidate uplink resources according to the rule that the frequency domain increases first and then the time domain increases. Wherein, the second type of terminal is an FD-FDD terminal, and the HD-FDD terminal is sorted using a sorting rule of the FD-FDD terminal. It should be noted that the embodiment in FIG. 7 mainly involves a 4-step RACH scenario, and the sorting of uplink resources can be regarded as the sorting of ROs. Among them, according to the provisions in the existing protocol, the ordering rules of the FD-FDD terminal for ROs include: for preambles with continuous indexes in the effective ROs in a PRACH slot, first sort the preamble index in the effective ROs according to the increment of the preamble index. Second, for frequency division multiplexed ROs, sort them in ascending order according to the frequency resource index. Thirdly, for the time-division multiplexed ROs in a PRACH slot, they are sorted in ascending order according to the time resource index.

For example, when a terminal device sorts valid ROs, it first sorts them in the order of increasing preamble index in one RO cycle. front of the frequency domain. Then in the frequency domain direction, the ROs are sorted incrementally, as shown in Figure 3, the two ROs in the first RO cycle are sorted in the frequency domain direction according to the RO increments. After sorting, the preamble number of the first RO is 0-3, and the The preamble numbers of the two ROs are 4-7. Finally, the ROs are sorted in ascending order in the time domain direction. As shown in Figure 3, the third RO is ranked after the first RO after the ROs are sorted in the time domain direction. The preamble number of the third RO is 8-11.

Wherein, the sorting of the N1 candidate uplink resources is used to determine the identifiers of the N1 candidate uplink resources, the identifier of the first downlink signal corresponds to the identifier of the first uplink resource, and both N1 and N2 are integers greater than or equal to 1. For example, in the RO cycle shown in Figure 5, one SSB corresponds to one RO. That is to say, when the first downlink signal is the SSB and the first uplink resource is the RO, the identifier of the SSB corresponds to the identifier of the RO. According to the identifier of the SSB, the terminal device determines from the N1 candidate ROs that the RO whose identifier corresponds to the identifier of the SSB is the first uplink resource corresponding to the first downlink signal.

703. The terminal device sends the first uplink channel to the network device in the first uplink resource.

Wherein, after determining the first uplink resource, the terminal device sends the first uplink channel in the first uplink resource. For example, the first uplink resource is a designated RO, and the terminal device sends a PRACH to the network device through the designated RO.

It can be seen that the present disclosure provides a resource allocation method. In this method, the HD-FDD terminal adopts the RO/PRU validity judgment rule and sorting rule of the FD-FDD terminal to avoid the conflict between the RO/PRU of the HD-FDD terminal and the FD-FDD terminal. Different mapping rules lead to confusion of network device identification and reduced reception performance.

FIG. 8 is a schematic flowchart of a fourth resource configuration method provided by the present disclosure. Wherein, the resource configuration method is implemented by the interaction between the terminal device and the network device. It should be noted that the terminal device interacting with the network device in the present disclosure is a half-duplex frequency division duplex HD-FDD terminal. The resource configuration method provided by the present disclosure is applied in a 2-step RACH scenario. The resource configuration method includes the following steps:

801. A terminal device determines a first uplink resource from N1 candidates of uplink resources of the first type.

802. The terminal device determines a second uplink resource corresponding to the first uplink resource from N3 candidate uplink resources of the second type.

Among them, the present disclosure respectively adopts two different validity judgment rules to judge the validity of the uplink resources for the uplink resources RO and PRU in the 2-step RACH scenario. Wherein, the N1 candidate uplink resources are valid uplink resources determined from the N2 first-type uplink resources according to the first validity judgment rule for the second-type terminal. Wherein, in this embodiment, it is assumed that the first type of uplink resources are ROs, for example, N2 first type uplink resources are N2 ROs. The terminal device selects N1 candidate ROs from the N2 ROs according to the first validity judgment rule for the second type of terminal. Wherein, the second type terminal is an FD-FDD terminal, and the HD-FDD terminal is judged by using the first validity judgment rule of the FD-FDD terminal.

In an implementation manner, the first validity determination rule for the second type of terminal includes: in the FDD cell, all of the N2 first type uplink resources are valid resources. In a TDD cell, among the N2 first-type uplink resources, the N1 candidate first-type uplink resources that do not collide with the downlink signal in time are all valid resources, or, in a TDD cell, the candidates included in the flexible resources are the first Type uplink resources are all valid resources. For a specific example, reference may be made to the description of the RO validity judgment in the embodiment in FIG. 7 , which will not be repeated here.

Wherein, for the first type of uplink resources, after determining that the N1 candidate first type uplink resources are all valid resources, the terminal device may also sort the N1 valid first type uplink resources. Wherein, the ranking among the N1 candidate uplink resources of the first type is determined according to the first sorting rule for the second type of terminal. For example, the terminal device determines the sorting among N1 valid ROs according to the sorting rule of the FD-FDD terminal for ROs. In an implementation manner, the first sorting rule for the second type of terminal includes: sorting the N1 candidate first type uplink resources according to the rule of increasing first in the frequency domain and then increasing in the time domain. For a specific example, reference may be made to the description of the sorting of ROs in the embodiment in FIG. 7 , which will not be repeated here.

Wherein, the ordering of the N1 first-type uplink resource candidates is used to determine the respective identities of the N1 first-type uplink candidate candidates. The identifier of the first downlink signal corresponds to the first type of uplink resource. For example, when the first downlink signal is an SSB and the first type of uplink resource is an RO, the identifier of the SSB corresponds to the identifier of the RO. According to the identifier of the SSB, the terminal device determines from the N1 candidate ROs that the RO whose identifier corresponds to the identifier of the SSB is the first uplink resource corresponding to the first downlink signal.

Wherein, the N3 candidate second-type uplink resources are effective uplink resources determined from the N4 second-type uplink resources according to the second validity judgment rule for the second-type terminal. Wherein, in this embodiment, it is assumed that the second-type uplink resources are PRUs, for example, N4 second-type uplink resources are N4 PRUs. The terminal device selects N3 candidate PRUs from the N4 PRUs according to the second validity judgment rule for the second type of terminal. That is to say, the HD-FDD terminal uses the second validity determination rule of the FD-FDD terminal to perform determination. Wherein, both N3 and N4 are integers greater than or equal to 1.

In one implementation, the second validity judgment rule for the second type of terminal includes: in the FDD cell, among the N4 second type uplink resources that do not conflict with the N1 candidate first type uplink resources on the time-frequency resource All of the N3 candidate uplink resources of the second type are valid resources. In a TDD cell, among the N4 second-type uplink resources, the N3 second-type candidate uplink resources that do not conflict with downlink signals and the N1 first-type candidate uplink resources on time-frequency resources are valid resources.

For example, in an FDD cell, all PRUs that do not overlap with valid ROs in time-frequency resources are valid. In a TDD cell, when the network device is not configured with direction indication information (for example, tdd-UL-DL-ConfigurationCommon is not configured), all PRUs that do not overlap with SSB and valid RO in time-frequency resources are valid. In a TDD cell, when the network device is configured with direction indication information (for example, tdd-UL-DL-ConfigurationCommon is configured), all PRUs that do not overlap with valid ROs in time-frequency resources are valid. For determining the validity of the RO, refer to the descriptions in the foregoing embodiments, and details are not repeated here.

Wherein, after the terminal device determines the valid uplink resources of the second type, the terminal device may also sort the valid uplink resources of the second type. In this embodiment, the ranking among the N3 candidate uplink resources of the second type is determined according to the second sorting rule for the second type of terminal. For example, the terminal device determines the ordering among the N3 effective PRUs according to the ordering rules of the FD-FDD terminal for PRUs. In an implementation manner, the second sorting rule for the second type of terminal includes: the N3 candidate uplink resources are sorted according to the rule of first increasing in frequency domain and then increasing in time domain. Among them, according to the provisions in the existing agreement, the FD-FDD terminal's ordering rules for PRUs include: for valid PRUs (including PUSCH occasion and DMRS), in the scenario of frequency division multiplexing PUSCH, firstly, according to the frequency resource index Sort in ascending order. Second, within the PUSCH occasion, sort according to the DMRS resource index in ascending order. Wherein, the DMRS resource index is determined according to the ascending order of the DMRS port index and the ascending order of the DMRS sequence index. Thirdly, for the time-division multiplexed PUSCHs in the PUSCH slots, they are sorted in ascending order according to the time resource index. Fourth, they are sorted in ascending order according to the index of the PUSCH slot.

For example, when sorting the valid PRUs, the terminal device first sorts them in ascending order according to the frequency resource index. In the PUSCH occasion, they are sorted in ascending order according to the DMRS resource index, as shown in Figure 3, in a PUSCH occasion, DMRS 1 is ranked before DMRS 2. For the time-division multiplexed PUSCH in the PUSCH slot, it is sorted according to the time resource index in ascending order, as in the PUSCH occasion in the first column in Figure 3, after sorting according to the time resource index in ascending order, the time resource index in the first row is 0-1 , the time index resource of the second row is 2-3. Then sort according to the increasing index of the PUSCH time slot, as in the PUSCH occasion in the first column in Figure 3, after sorting according to the increasing index of the PUSCH time slot, the index of the PUSCH occasion in the first column is smaller than the PUSCH occasion in the second column index of.

Wherein, the ranking of the N3 candidate second-type uplink resources is used to determine respective identities of the N3 candidate second-type uplink resources, and the identities of the first uplink resources correspond to the identities of the second uplink resources. That is to say, due to the mapping relationship between RO and PRU, after the terminal device determines the identifier of RO from N1 candidate first-type uplink resources, the terminal device determines the identifier from N3 candidate second-type uplink resources according to the identifier of RO. The PRU corresponding to the identifier of the RO is the second uplink resource corresponding to the first uplink resource.

803. The terminal device sends the first uplink channel to the network device in the first uplink resource, and sends the second uplink channel to the network device in the second uplink resource.

For example, the first uplink resource is a designated RO, and the terminal device sends a PRACH to the network device through the designated RO. The second uplink resource is a designated PRU, and the terminal device sends a PUSCH to the network device through the designated PRU.

It can be seen that the present disclosure provides a resource configuration method, in which the HD-FDD terminal adopts the RO/PRU validity judgment rules and sorting rules of the FD-FDD terminal for the first type of uplink resources and the second type of uplink resources respectively, to avoid The RO/PRU mapping rules of HD-FDD terminals and FD-FDD terminals are different, which leads to confusion of network device identification and degradation of receiving performance.

Finally, two application embodiments are laid out (including the application of the above resource configuration method to two-step random access scenarios and four-step random access scenarios).

Specific steps when the resource configuration method provided in the embodiments of FIG. 4 to FIG. 8 are applied to a random access scenario are described in detail below.

FIG. 9 is a schematic flowchart of the resource configuration method provided by the present disclosure applied to a four-step random access scenario. Wherein, the terminal device interacting with the network device in this disclosure is an HD-FDD terminal, and the specific interaction process includes the following steps:

901. The terminal device determines a first uplink resource for sending a PRACH according to direction indication information or according to a first downlink signal.

In one implementation, when the terminal device determines the first uplink resource for sending the PRACH according to the direction indication information, the following two implementations are included:

Way 1: The terminal device determines one or more second periods for sending the PRACH from the first period according to the direction indication information. Specifically, the direction indication information is used to indicate the time domain resource used by the terminal device to send the PRACH in the first period. The time domain resource used by the terminal device to send the PRACH includes one or more second periods, where the second period is defined as one or more RO periods (or RO mapping periods), and the first period is defined as including multiple second periods. Wherein, for the specific description of the direction indication information, the first cycle, and the second cycle, refer to the corresponding description in the embodiment in FIG. 4 , and details are not repeated here. According to the direction indication information, the terminal device can judge whether each RO cycle (or RO mapping cycle) can be used for the terminal device to send PRACH, so as to determine the RO cycle (or RO mapping cycle) for sending PRACH.

Mode 2: The terminal device determines resources for the HD-FDD terminal to send the PRACH according to the direction indication information and the first configuration information. Specifically, the first configuration information is used to configure the RO, and the direction indication information is used to indicate the time domain resource for sending the PRACH. Wherein, the time domain resource used for the terminal device to send the PRACH includes the time domain position of the RO for sending the PRACH, or one or more second periods. The second period is defined as one or more RO periods (or RO mapping periods), and the first period is defined as including multiple second periods. For specific descriptions of the first configuration information, direction indication information, first cycle, and second cycle, refer to the corresponding description in the embodiment in FIG. 6 , and details are not repeated here. According to the direction indication information, the terminal device can determine the time domain position of the RO used to send the PRACH, or the RO period, or the RO mapping period.

In an implementation manner, when the terminal device determines uplink resources for sending the PRACH according to the first downlink signal, the terminal device determines the first uplink resource corresponding to the first downlink signal from the N1 candidate uplink resources. Specifically, the terminal device uses the first validity judgment rule and the first sorting rule of the FD-FDD terminal to determine N1 candidate ROs; then, according to the received SSB, selects the RO corresponding to the SSB from the N1 candidate ROs, and uses the SSB The corresponding RO sends a PRACH to the network device. For a specific implementation manner, refer to the corresponding description in the embodiment in FIG. 7 , and details are not repeated here.

902. The terminal device sends a preamble (PRACH) to the network device by using the first uplink resource; correspondingly, the network device receives the preamble (PRACH) from the terminal device.

Wherein, the terminal device sends a preamble (PRACH) to the network device by using the time domain position/RO period/RO mapping period/RO determined in step 901, also called message 1 (Msg1). Wherein, preamble is a sequence, which is used to notify the network device that there is a random access request, and enable the network device to estimate the transmission delay between the terminal device and the network device. Make the network device calibrate the uplink timing (uplink timing) of the terminal device, and notify the terminal device through a timing advance (timing advance, TA) command (including calibration information). According to the existing agreement, in a cell, the network can configure up to 64 preambles with different indexes, and the preambles with different indexes are distinguished by different root sequences or different cyclic shifts of the same root sequence.

903. The network device sends a random access response message to the terminal device; correspondingly, the terminal device receives a random access response message from the network device.

Wherein, when the network device detects the preamble, it sends a random access response message, also called message 2 (Msg2), to the terminal device. For the specific implementation manner, refer to the description of the corresponding steps in the existing protocol, which will not be repeated here.

904. The terminal device sends an RRC connection request message to the network device; correspondingly, the network device receives the RRC connection request message from the terminal device.

Wherein, after the terminal receives the random access response message, if the preamble index in the random access response message includes the index of the preamble sent by the terminal device to the network device, the terminal device determines that the random access response message is for its own random access response message. Access response, and the random access response message determines the PUSCH resource for sending message 3 (Msg3). Wherein, the terminal may initiate an RRC connection request in Msg3. For the specific implementation manner, refer to the description of the corresponding steps in the existing protocol, which will not be repeated here.

905. The network device sends a conflict resolution message to the terminal device that has successfully accessed; correspondingly, the terminal device receives the conflict resolution message from the network device.

Wherein, when the network device receives Msg3 sent by the terminal device, it may return a contention resolution message (contention resolution), also called message 4 (Msg4), to the terminal device that has successfully accessed. For the specific implementation manner, refer to the description of the corresponding steps in the existing protocol, which will not be repeated here. It should be noted that a terminal device that has not successfully accessed can re-initiate a four-step random access.

Optionally, after step 905, step 906 is also included, when the terminal device receives Msg4 and correctly demodulates the physical uplink shared channel (physical uplink shared channel, PUSCH), the terminal device passes the physical downlink control channel (physical downlink control channel, PUCCH) ) sends an acknowledgment message (ACK) to the network device. Wherein, when the terminal equipment fails to correctly demodulate the PUSCH, the terminal equipment sends a non-acknowledgment message (NACK) to the network equipment through the PUCCH. For the specific implementation manner, refer to the description of the corresponding steps in the existing protocol, which will not be repeated here.

FIG. 10 is a schematic flowchart of the resource configuration method provided by the present disclosure applied to a two-step random access scenario. Wherein, the terminal device interacting with the network device in this disclosure is an HD-FDD terminal, and the specific interaction process includes the following steps:

1001. A terminal device determines a first uplink resource for sending a PRACH according to direction indication information or a first downlink signal.

Way 1: The terminal device determines one or more second periods for sending the PRACH from the first period according to the direction indication information. Wherein, for the specific description of mode 1, refer to the corresponding description in the embodiment in FIG. 9 , and details are not repeated here.

Mode 2: The terminal device determines resources for the HD-FDD terminal to send the PRACH according to the direction indication information and the first configuration information. Wherein, for the specific description of the second manner, refer to the corresponding description in the embodiment in FIG. 9 , and details are not repeated here.

In an implementation manner, when the terminal device determines uplink resources for sending the PRACH according to the first downlink signal, the terminal device determines the first uplink resource corresponding to the first downlink signal from the N1 candidate uplink resources. For a specific implementation manner, refer to the corresponding description in the embodiment in FIG. 9 , and details are not repeated here.

1002. The terminal device determines a second uplink resource for sending a PUSCH according to the direction indication information or according to the first uplink resource.

In one implementation, since the RO and the PRU have a one-to-one mapping relationship, when the terminal device determines the first uplink resource (RO) used to send the PRACH according to the direction indication information, the terminal device also determines the RO corresponding The PRU is the second uplink resource used to send the PUSCH. For example, the terminal device determines one or more second periods for sending the PRACH from the first period according to the direction indication information. A second cycle may be an RO mapping cycle, and a second cycle is also a PRU mapping cycle. Then the terminal device determines the PRU mapping period for sending the PUSCH, and uses the corresponding PRU to send the PUSCH.

In an implementation manner, when the terminal device determines the uplink resource used for sending the PUSCH according to the first uplink resource, the terminal device determines the second uplink resource corresponding to the first uplink resource from the N3 candidate uplink resources. Specifically, the terminal device uses the second validity judgment rule and the second sorting rule of the FD-FDD terminal to determine N3 candidate PRUs; then, according to the determined RO, selects the PRU corresponding to the RO from the N3 candidate PRUs, and uses The PRU corresponding to the RO sends a PUSCH to the network device. For a specific implementation manner, refer to the corresponding description in the embodiment in FIG. 8 , and details are not repeated here.

1003. The terminal device sends a preamble to the network device by using the first uplink resource, and sends a PUSCH to the network device by using the second uplink resource; correspondingly, the network device receives the preamble and the PUSCH from the terminal device.

Wherein, the terminal device sends preamble and PUSCH to the network device, and this message is also called MsgA. For the specific implementation manner, refer to the description of the corresponding steps in the existing protocol, which will not be repeated here.

1004. The network device sends a random access response message to the terminal device; correspondingly, the terminal device receives a random access response from the network device.

Wherein, the network device sends a random access response message, also called MsgB, to the terminal device. For the specific implementation manner, refer to the description of the corresponding steps in the existing protocol, which will not be repeated here. It should be noted that a terminal device that fails to access can re-initiate two-step random access, or, after several failed attempts, initiate four-step random access.

Optionally, after step 1004, step 1005 is also included. When the terminal device receives the MsgB and correctly demodulates a physical downlink shared channel (PDSCH), the terminal device sends an ACK to the network device through the PUCCH. Wherein, when the terminal equipment fails to demodulate the PDSCH correctly, the terminal equipment sends a NACK to the network equipment through the PUCCH. Optionally, when the terminal device fails to identify the DCI for scheduling the MsgB PDSCH, the terminal device does not send ACK/NACK to the network device. When the network device does not receive the ACK/NACK within a time window, it can resend the MsgB to the terminal device.
