Description

Communication method and communication device

technical field

The present application relates to the field of communication, and more particularly, to a communication method and a communication device.

Background technique

The 3rd generation partnership project is exploring the subject of supporting reduced capability (REDCAP) user equipment (UE) in new radio (NR) systems. REDCAP UE is a capability relative to UEs supported in existing NR systems, such as enhanced mobile broadband (eMBB) UE and ultra-relaible and low latency communication (URLLC) UE. The lower UE type can be used for massive machine type communication (mMTC) scenarios. The main feature of REDCAP UE is to meet its higher UE energy saving requirements by reducing or limiting the UE's capabilities. For example, the bandwidth capabilities of REDCAP UEs can be limited relative to eMBB UEs. For example, the maximum partial bandwidth (BWP) that a REDCAP UE can support is reduced to 20 megahertz (megahertz, MHz) or 10 MHz. For another example, compared to an eMBB UE, the signal processing capability (processing capability) of the REDCAP UE may be reduced, the processing delay requirement (processing time) may be relaxed, and/or the antenna capability may be reduced. For another example, REDCAP UE only supports half-duplex frequency division duplex (HD-FDD) capability in frequency division duplex (FDD) mode, and REDCAP UE does not support full-duplex capability in HD-FDD mode. Duplex frequency division duplex (Full-duplex FDD, FD-FDD) simultaneous reception and transmission behavior, and switching between transmission and reception requires a guard time (guard time). How to make REDCAP UE and network equipment communicate effectively is a current research focus.

For example, the network device uses signaling, such as system information (such as system information block (SIB)), common RRC signaling, terminal equipment-specific RRC signaling, terminal equipment-specific or common MAC CE, or terminal equipment. A device-specific or common DCI that indicates to the terminal device the configuration information of the first time unit format configuration information group, the configuration information of the second time unit format configuration information group, and/or the configuration information of the third time unit format configuration information group configuration information. The common signaling is common to multiple terminal devices, such as a group of terminal devices in a cell or all terminal devices in a cell.

For example, the indication information includes an indication field A1 and an indication field A2, and the indication field A1 and the indication field A2 are respectively used to indicate a time unit format configuration information group (for example, the indication field A1 and the indication field A2 respectively indicate a time unit format configuration information group The indication information further includes an indication field B1 and an indication field B2, and the indication field B1 and the indication field B2 are respectively used to indicate the identification of the time unit format configuration information in the corresponding configuration information group. Specifically, the indication field A1 corresponds to the indication field B1, and the indication field B1 is used to indicate the identifier of one or more time unit format configuration information in the time unit format configuration information group indicated by the indication field A1. The indication field A2 corresponds to the indication field B2, and the indication field B2 is used to indicate the identifier of one or more time unit format configuration information in the time unit format information group indicated by the indication field A2.

For example, the protocol specifies the first time unit format configuration information group and the third time unit format configuration information group, and the identifiers are 0 and 1 respectively, the indication field A1 and the indication field A2 are 2 bits respectively, and the indication field B1 and the indication field B2 are respectively 2 bits. 6 bits respectively. In the indication information sent by the time unit n, the network device indicates that the field A1 indicates "00", indicating that the field A1 indicates the first time unit format configuration information group, the field B1 indicates "000100", and the field B1 indicates the first time In the unit format configuration information group, the first time unit format configuration information identified as 4 (ie, the decimal value corresponding to binary 000100), the first time unit format configuration information identified as 4 indicates the format of one time unit. In the indication information, the indication field A2 indicates "01", indicating that the indication field A2 indicates the third time unit format configuration information group, the indication field B2 indicates "000011", and the indication field B2 indicates that the third time unit format configuration information group is identified as 3 (ie, the decimal value corresponding to 000011 in binary) third time unit format configuration information, where the third time unit format configuration information marked as 3 indicates the format of each symbol in the L time units. Therefore, the indication information indicates a total of 2 time unit format configuration information (ie K=2), and the 2 time unit format configuration information indicates a total of L+1 time units (ie N=L+1), such as the third time and time The unit format configuration information group is shown in Table 3.

That is, the indication information indicates the format of 11 time units starting from time unit n+i. The 11 time units and time unit format configuration information starting from time unit n+i can be determined according to the order of the indication field A1 and the indication field A2 in the indication information, or can be determined according to the order of the indication field B1 and the indication field B2 in the indication information corresponding relationship.

In an example, the indication field B1 and the indication field B2 are arranged in order in the indication information, then the format configuration information of the first time unit indicated by the indication field B1 is used to configure the format of the time unit n+i, and the third time unit indicated by the indication field B2 is used to configure the format of the time unit n+i. The formats of the 10 time units indicated by the time unit format configuration information sequentially correspond to the formats of time unit n+i+1 to time unit n+i+10, but the present application is not limited thereto.

In another example, the indication field A1 and the indication field A2 in the indication information may indicate the same time unit format configuration information group, such as the first time unit format configuration information group, and the indication field B1 and the indication field B2 respectively indicate the first time unit. A first time unit format configuration information in the format configuration information group, the first time unit format configuration information indicated by the indication field B1 and the indication field B2 may be the same or different, indicating time unit n+i and time unit n+i respectively. +1 for the format, but this application is not limited to that.

In another example, the indication field A1 and the indication field A2 in the indication information may both indicate the third time unit format configuration information group, and the third time unit format configuration information indicated by the indication field B1 and the indication field B2 may be the same or different, The two third time unit format configuration information indicates the format of a total of 20 time units starting from time unit n+i, but the present application is not limited to this. Optionally, at this time, the indication domain A1 and the indication domain A2 may be a shared indication domain.

In another example, the indication field A1 in the indication information indicates the first time unit format configuration information group, the indication field B1 indicates a first time unit format configuration information, the indication field A2 indicates a value other than "00" or "01", Or the default value, such as "11", indicates that the indication field A2 does not indicate the time unit format configuration information group, then the indication information indicates the format of 1 time unit, that is, the format matching information of the first time unit indicated by the indication field B1 is used. In the format of indicating the time unit n+i, but the present application is not limited to this.

For another example, the network device sends a radio resource control (radio resource control, RRC) message to the terminal device, where the RRC message includes configuration information for indicating the time unit format configuration information group, for example, indicating the first time unit format configuration information. Group information (such as indicating Table 1 in the form of a list or table), information of the second time unit format configuration information group (such as indicating Table 2 in the form of a list or table), and information of the third time unit format configuration information group (For example, Table 3 is indicated in the form of a list or table) information of three time unit format configuration information groups in total, and indicates the identifier corresponding to each time unit format configuration information group. After the terminal device receives the RRC message, the network device may send the indication information in the time unit n, and the indication information notifies the terminal device of the time unit by indicating at least one of the time unit format configuration information groups and the time unit format configuration information therein. The format of N time units starting from n+i, that is, one or more resources among uplink resources, downlink resources and flexible resources included in the N time units, but the present application is not limited thereto.

As an example and not limitation, the indication information is dedicated information of the terminal device. Optionally, the indication information may be a media access control (media access control, MAC) control element (control element, CE) and/or downlink control information (downlink control information, DCI). For example, the DCI is scrambled by a dedicated (or specific) identifier of the terminal device, such as a radio network temporary identifier (RNTI). For example, the MAC CE is carried on a downlink shared channel (physical downlink shared channel, PDSCH) scheduled by a DCI dedicated to the terminal device.

Or, the indication information is information shared or common by multiple terminal devices, and the indication information may be MAC CE. For example, the MAC CE is carried on the PDSCH scheduled by the common DCI. The common DCI may be scrambled by a common identifier of multiple terminal devices, such as RNTI.

For example, the indication information is MAC CE, and the indication information may be as shown in Figure 3, including 2 bytes, wherein, byte 0 includes a 3-bit indication field A1, which is used to indicate the system preset or network configuration time unit One of the format configuration information groups, byte 0 also includes a 5-bit indication field B1, used to indicate one or more time unit format configuration information in the time unit format configuration information group indicated by the indication field A1, byte 1 It includes a 3-bit indication field A2, which is used to indicate one of the time unit format configuration information groups preset by the system or network configuration, and a 5-bit indication field B2 is also included in byte 1, which is used to indicate that the indication field A2 indicates. One or more time unit format configuration information in the time unit format configuration information group, but the present application is not limited to this.

For another example, the indication information is MAC CE, and the indication information may be as shown in Figure 4, including 3 bytes, wherein, byte 0 includes a 3-bit indication field A1, which is used to indicate the time of system preset or network configuration One of the unit format configuration information groups, such as the third time unit format configuration information group, byte 0 also includes an indication field B1 for indicating one or more time unit formats in the third time unit format configuration information group Configuration information, for example, the third time unit format configuration information group may include 16 third time unit format configuration information, then the indication field B1 includes 4 bits from bit 3 to bit 6 in byte 0. The last bit is reserved. Byte 1 includes a 3-bit indication field A2, which is used to indicate one of the time unit format configuration information groups preset by the system or network configuration, such as the first time unit format configuration information group, for example, the first time unit format The information group includes 512 first time unit format information, then the remaining 5 bits of the second byte (byte 1) and the 4 bits of the third byte (byte 0) have a total of 9 bits as the indication field B2. For indicating a time unit format configuration information in the first time unit format configuration information group, the remaining 5 bits of the third byte are reserved bits, but the present application is not limited thereto.

For another example, the indication information may be a DCI dedicated to the terminal device, for example, the format of the DCI is DCI format 0_1, DCI format 0_0, DCI format 1_1, or DCI format 1_0. The DCI may be transmitted in a UE specific search space. And/or the DCI is scrambled by a terminal device-specific wireless network temporary identification (radio network temporary identification, RNTI), but the present application is not limited to this.

Optionally, the indication information may further include an indication field C, where the indication field C is used to indicate the applicable scope of the indication information.

For example, the indication field C includes 1 bit, and when the indication field C indicates "0", it indicates that the format of N time units indicated by the indication information is applied to N time units starting from time unit n+i. When the indication field C indicates "1", it means that if the network device has configured the format of the time unit n+i starting time unit before the indication information, the indication information is used to indicate that the N time units are pre-configured as The format of the time unit of the flexible resource or the format of the time unit of the unconfigured format, or indicating the time unit of the unconfigured format among the N time units. As shown in Figure 5, the indication information indicates the format of 10 time units, and the network device pre-configures the format of the 10 time units for the terminal device. If the indication field C in the indication information indicates "1", it means that The indication information is used to indicate the format of time unit 2 to time unit 6 that are pre-configured as flexible resources in the 10 time units, or the indication information is used to indicate the time unit 2 of the 10 time units that are pre-configured with flexible resources. The format up to time unit 6 is rewritten as uplink resources. The other time units of the 10 time units maintain the preconfigured format. If the indication field C indicates "0", it means that regardless of whether there is a pre-configured format, the 10 time units apply the format indicated by the indication information, that is, they are all uplink resources, but the present application is not limited to this.

Optionally, the network device sends first configuration information to the terminal device, where the first configuration information is used to configure each time unit in the multiple time units as an uplink resource, a downlink resource or a flexible resource.

In an embodiment, the terminal device determines one or more of uplink resources, downlink resources and flexible resources included in the flexible resources in the multiple time units and the overlapping resources in the N time units according to the indication information .

That is to say, the terminal device determines the format of multiple time units after receiving the first configuration information. When the terminal device receives the indication information and determines that the N-format time unit indicated by the indication information overlaps with the multiple time units, the indication The information can only rewrite the format of the resource in which the flexible resources in the multiple time units overlap with the N time units. In other words, the terminal device does not expect the indication information to rewrite the format of the time unit or sub-time unit indicated by the first configuration information as the uplink resource or the downlink resource. For example, the first configuration information configures one time unit among the multiple time units as a flexible resource, the indication information indicates that the time unit is a downlink resource or an uplink resource, and the terminal device determines the format of the time unit according to the indication information after receiving the indication information . For another example, the first configuration information configures a time unit as an uplink resource, and the indication information indicates that the symbols in the time unit are downlink resources or flexible resources. After receiving the indication information, the terminal device still configures the time unit according to the first configuration information. unit as an uplink resource.

In another embodiment, if the N time units indicated by the indication information overlap with multiple time units in the configuration format of the first configuration information, the terminal device determines the format of the N time units according to the indication information.

That is to say, the first configuration information configures the format of multiple time units. If after receiving the indication information, the terminal device determines that the N time units indicated by the indication information overlap with the multiple time units, the format of the overlapped part is Determined according to the indication of the indication information.

Optionally, the indication information includes a first indication field, where the first indication field is used to indicate whether the indication information can rewrite the uplink resources or downlink resources configured by the first configuration information.

For example, the first indication field includes 1 bit, and when the first indication field indicates "1", it indicates that the indication information can rewrite the uplink resource or downlink resource configured by the first configuration information, and the terminal device receives the indication of the first indication field After the indication information of "1", the format of the N time units indicated by the indication information is determined according to the indication information. When the first indication field indicates "0", it means that the indication information cannot rewrite the uplink resources or downlink resources configured by the first configuration information. The time units overlap. When the overlapping resources include flexible resources, the format of the flexible resources in the overlapping resources can be rewritten by the indication information. When the overlapping resources include uplink resources or downlink resources, the indication information cannot rewrite the overlapping resources. The uplink resources and downlink resources included in , but this application is not limited to this.

S220, the terminal device determines one or more resources among uplink resources, downlink resources and flexible resources included in the N time units according to the indication information.

After receiving the indication information in S210, the terminal device determines one or more resources among uplink resources, downlink resources and flexible resources included in the N time units indicated by the indication information according to the indication information. That is, the format of the N time units indicated by the indication information is determined.

The wireless communication method provided by the present application further includes that the network device can directly indicate the format of the time unit through MAC CE and/or DCI.

For example, it is specified that every w bits in the MAC CE and/or DCI are used to indicate the format of one time unit, such as w=2, the 2 bits corresponding to one time unit indicate "00", indicating that the time unit is an uplink resource, indicating "01" indicates that the time unit is a downlink resource, and an indication of "10" indicates that the time unit is a flexible resource, but the present application is not limited to this. The method enables the terminal device and the network device to reach a consensus on the format of the event unit through MAC CE and/or DCI, thereby improving the reliability of communication.

FIG. 6 is a schematic flowchart of a wireless communication method 600 provided by an embodiment of the present application. The wireless communication method shown in FIG. 6 may be performed by a network device or by a terminal device. The following description is given by taking the method being executed by a terminal device as an example. The network device performs the corresponding behavior, for example, the terminal device sends corresponding information to the network device on the resource determined according to the method shown in FIG. Information corresponding to the resource is received from the terminal device. Alternatively, the network device sends the information corresponding to the resource to the terminal device, and the terminal device receives the information corresponding to the resource from the network device at the resource. For the network device to perform the wireless communication method shown in FIG. 6 , reference may be made to the following description of the terminal device, which will not be repeated for brevity.

S610: The terminal device determines that the first resource and the second resource overlap at the third resource location, the first resource is used to carry the first information, and the second resource is used to carry the second information.

The network device may configure the terminal device with a first resource for carrying the first information and a second resource for carrying the second information. The first resource and/or the second resource may be a periodic resource or a semi-static resource (or called a semi-persistent resource), wherein the semi-static resource refers to a period of time. A resource that occurs periodically over time.

As an example and not limitation, the first resource or the second resource is one of the following resources:

Configure grant (CG) resources for physical uplink shared channel (PUSCH), sounding reference signal (SRS) resources, and physical uplink control channel (PUCCH) resources , physical random access channel (PRACH) resources, search space (search space), semi-persistent channel state information-reference signal (SP-CSI-RS) resources and Semi-persistent scheduling-physical downlink shared channel (SPS-PDSCH) resources.

In other words, the first information or the second information is one of the following information:

CG uplink data, SRS, uplink control information (uplink control information, UCI), random access signal, DCI, SP-CSI-RS and SPS downlink data.

For example, as shown in FIG. 7 , the first resource is a periodic resource with a period of 6 time units, the second resource is a periodic resource with a period of 4 time units, and the first resource and the second resource are in the first time unit. The overlapped part is the third resource. In other words, the first resource and the second resource overlap in the third resource position within the first time unit, but the present application is not limited to this. Since the first resource and the second resource overlap, a terminal that is not full-duplex frequency division duplex (FD-HDD) can only send or receive corresponding information on one resource. The network device and the terminal device need to determine the specific information. Whether the first information or the second information is sent or received.

S620: The terminal device determines that the priority of the first resource is higher than the priority of the second resource, and sends or receives the first information on the first resource.

It can also be described that the terminal device determines that the priority of the first resource is higher than the priority of the second resource, and sends or receives the first information on the third resource.

Correspondingly, the network device determines that the priority of the first resource is higher than the priority of the second resource, and receives or sends the first information on the first resource. For example, if the first information is uplink information, the first resource is an uplink resource, the terminal device sends the first information on the first resource, and the network device receives the first information on the first resource. If the first information is downlink information, the first resource is a downlink resource, the network device sends the first information on the first resource, and the terminal device receives the first information on the first resource.

In an implementation manner, the network device sends second configuration information and third configuration information to the terminal device, where the second configuration information is used to configure the priority of the first resource, and the third configuration information is used to configure the priority of the second resource. class. Correspondingly, the terminal device receives the second configuration information and the third configuration information from the network device.

The terminal device may determine, according to the second configuration information and the third configuration information, that the priority of the first resource is higher than the priority of the second resource. That is, the terminal device compares the priority of the first resource with the priority of the second resource, and sends or receives information corresponding to the high-priority resource on the resource with the higher priority.

For example, the first resource is CG PUSCH, the second configuration information may be configuration authorization configuration information, which can be written as ConfiguredGrantConfig, and the configuration authorization configuration information includes the priority parameter of the CG PUSCH, or the priority parameter of the CG uplink data , the priority parameter can be written as Priority, the parameter can be an enumeration parameter, the network device can choose one of the priorities {I, II, III, IV}, and configure it as the priority of the CG PUSCH or CG uplink data . For example, the priority parameter in the configuration authorization configuration information may be as follows, but the present application is not limited thereto.

ConfiguredGrantConfig::=SEQUENCE{

…

Priority ENUMERATED{I,II,III,IV}

…

}

The second resource may be a search space, and the third configuration information may be search space configuration information, which may be written as SearchSpace. The search space configuration information includes the priority parameter of the search space, or the DCI carried in the search space. Priority parameter, the priority parameter can be written as Priority, this parameter can be an enumeration parameter, the network device can choose one of the priority {I, II, III, IV}, and configure it as the priority of the search space or DCI class. For example, the priority parameter in the search space configuration information may be as follows, but the present application is not limited thereto.

SearchSpace::=SEQUENCE{

…

Priority ENUMERATED{I,II,III,IV}

…

}

For example, the network device configures the priority of the CG PUSCH (that is, an example of the first resource) by configuring the authorization configuration information to be I, and configures the priority of the search space (that is, an example of the second resource) by configuring the search space configuration information to be III. and notify the terminal device through the second configuration information and the third configuration information respectively. When the terminal device needs to send uplink data on the CG PUSCH, and the CG PUSCH and the search space overlap at the third resource position in the first time unit, the network device and the terminal device compare the priorities of the CG PUSCH and the search space, For example, the larger the priority value, the higher the priority. The network device and the terminal device can determine that the priority I of the CG PUSCH is higher than the priority III of the search space. The terminal device sends uplink data to the network device on the CG PUSCH, and does not receive the DCI in the search space. The network device receives the uplink data from the terminal device on the CG PUSCH, and no longer sends the DCI of the terminal device in the search space, but this The application is not limited to this.

Optionally, the first resource includes at least one first sub-resource, wherein at least one of the following information of different first sub-resources is different: frequency, time, type of the first information and the first sub-resource The type of resource, each of the first sub-resources in the at least one first sub-resource corresponds to a priority, the second resource includes at least one second sub-resource, wherein the following information of different second sub-resources is At least one item is different: frequency, time, type of the second information, and type of the second resource, and each of the second sub-resources in the at least one second sub-resource corresponds to a priority. The terminal device specifically determines that the priority of the first sub-resource corresponding to the third resource is higher than the priority of the second sub-resource corresponding to the third resource, and sends the first information on the first resource.

That is, the network device divides the first resource into at least one first sub-resource according to frequency, time, the type of the first information and/or the type of the first resource, and divides the first resource into at least one first sub-resource according to frequency, time, and the type of the second information. The type and/or the type of the second resource divides the second resource into at least one second sub-resource, and informs the terminal device. The second configuration information specifically configures the priority of each first sub-resource and the information of each first sub-resource, and the third configuration information configures the priority of each second sub-resource and each second sub-resource Information. In the case where the first resource and the second resource overlap at the third resource position, the terminal device compares the priority of the third resource to the first sub-resource with the priority of the second sub-resource corresponding to the third resource, and the priority is The information corresponding to the resource is sent or received on the higher-level resource.

For example, in the CG PUSCH configured by the network device for the terminal device, the resources at the first frequency position are the resources of the first CG channel, and the priority is II; the resources at the second frequency position are the resources of the second sub-CG channel, and the priority is II. Class is III. And, the network device can also configure the search space, the common search space (common search space, CSS) is the first sub-search space, and the priority is 1; it is used to detect the terminal equipment-specific DCI (for example, through the cell-RNTI (cell-RNTI, The UE-specific search space (UE-specific search space, USS) of C-RNTI) scrambled DCI, etc.) is the second sub-search space with a priority of II; the USS used to detect DCI in DCI format 0_1 and DCI format 1_1 is The third sub-search space, the priority is III. When the terminal device needs to send the CG PUSCH of uplink data and the search space overlaps in the third resource, if the terminal device determines that the sub-CG channel corresponding to the third resource is the second sub-CG channel, the priority is III, and the third resource is the same as the third sub-CG channel. The sub-search space corresponding to the resource is the second sub-search space USS, the priority is II, and the priority of the second sub-search space (ie, an example of the first sub-resource) is higher than that of the second sub-CG channel (ie the second sub-CG channel). an example of a sub-resource), the terminal device determines to detect DCI on the second sub-search space. The network device uses the same method to determine that the priority in the second sub-search space is higher than that of the second sub-CG channel, but the present application is not limited to this.

In another embodiment, the priority of semi-static resources and/or periodic resources is specified by the protocol.

For example, the protocol stipulates that the priority of the CG PUSCH is higher than the first search space. If the CG PUSCH overlaps with the first sub-search space, the terminal device can send uplink data on the CG PUSCH without detecting DCI in the first sub-search space. The protocol can also specify that the priority of the third sub-search space is higher than that of the CG PUSCH. When the third sub-search space overlaps with the CG PUSCH, the terminal device receives and detects DCI in the third sub-search space, and does not send uplink data on the CG PUSCH. . Or the protocol specifies the priority value of each semi-static resource and/or periodic resource. The network device and the terminal device can compare the priority of the conflicting resource and determine to send or receive the corresponding information on the resource with high priority. The application is not limited to this. Optionally, when two resources with the same priority specified in the protocol overlap, the priority of the two resources may be further determined according to the previous business situation, or in other words, the specific priority of the two resources may be further determined according to the previous business situation. The corresponding information is sent on one of the resources.

Optionally, the first resource and the second resource are resources in a first time unit, the first resource is an uplink resource, the second resource is a downlink resource, the first information is uplink information, and the second information is downlink information, the Qth time unit before the first time unit includes uplink resources and carries uplink information, and it is determined that the priority of the first resource is higher than the priority of the second resource; or, before the first time unit The Qth time unit of , includes downlink resources and does not carry downlink information, and it is determined that the priority of the first resource is higher than the priority of the second resource, or,

The first resource is a downlink resource, the second resource is a downlink resource, the first information is downlink information, the second information is uplink information, and the Qth time unit before the first time unit includes uplink resources, and is not Bearing uplink information, it is determined that the priority of the first resource is higher than the priority of the second resource; or, the Qth time unit before the first time unit includes downlink resources and carries downlink information, and it is determined that the first time unit The priority of the resource is higher than the priority of the second resource, wherein Q is a positive integer. The terminal device and the network device use the Qth time unit before the first time unit in which the resources overlap as a reference, and determine the difference between the first resource and the second resource according to the resource type (uplink resource or downlink resource) in the Qth time unit. priority. The main consideration is whether there is enough time for uplink and downlink switching (or switching between transmission and reception).

Optionally, the time length of the Q time units is greater than or equal to a first time interval, where the first time interval is a time interval for switching from a receiving state to a sending state or a time interval from a sending state to a receiving state.

For example, Q=2, that is to say, the terminal device needs two time units to switch the sending and receiving state. If the CG PUSCH and the search space configured by the network device overlap in the first time unit, as shown in Figure 8, the terminal device and the network The device determines that the resource in the second time unit before the first time unit carries the uplink information, indicating that the terminal device does not have enough time for 2 time units, and switches to the receiving state to receive and detect DCI in the first time unit, Therefore, the terminal device can send uplink data on the CG PUSCH in the first time unit. Or, if the resource in the time unit does not carry downlink information, the terminal device has 2 time units and switches from the receiving state to the sending state, so the terminal device sends the uplink data on the CG PUSCH in the first time unit, DCI is not detected within the search space in the first time unit. Correspondingly, the network device receives the uplink data from the terminal device on the CG PUSCH resource in the first time unit, but does not send the DCI to the terminal device in the search space in the first time unit. If the resources in the second time unit before the first time unit carry downlink information, the terminal device detects DCI in the search space in the first time unit, and does not send uplink data on the CG PUSCH in the first time unit . If the resources included in the second time unit before the first time unit do not carry uplink information, the terminal device detects DCI in the search space in the first time unit, and does not send uplink information on the CG PUSCH in the first time unit data. The network device may send DCI to the terminal device in the search space in the first time unit, but not receive uplink data from the terminal device on the CG PUSCH in the first time unit, but the present application is not limited to this.

Optionally, at least T resources between the Rth time unit before the first time unit and the Qth time unit before the first time unit carry the first information, and it is determined that the priority of the first resource is higher than the priority of the first resource. Two priorities of resources, where R is an integer greater than or equal to Q, and Q and T are integers greater than 0.

For example, as shown in FIG. 9 , the PUCCH and the search space overlap in the first time unit, such as Q=3, R=6, T=2. The terminal device and the network device determine whether the four time units between the sixth time unit and the third time unit before the first time unit include at least two resources that carry UCI, if as shown in FIG. 9 at least two resources are included. If the two resources carry the UCI, the terminal device can send the UCI on the PUCCH in the first time unit, and the network device receives and monitors the UCI from the terminal device on the PUCCH. If it is not satisfied that at least two resources carry UCI, the network device may send DCI to the terminal device in the search space in the first time unit, and the terminal device receives and detects DCI in the search space in the first time unit. If the four time units between the sixth time unit before the first time unit and the third time unit include at least two resources that carry DCI, the network device may search the space in the first time unit The DCI is sent internally to the terminal device, and the terminal device receives and detects the DCI in the search space in the first time unit. If it is not satisfied that at least two resources carry DCI, the terminal device may send the UCI on the PUCCH in the first time unit, and the network device receives and detects the UCI from the terminal device on the PUCCH. Optionally, if both at least two resources carry DCI and at least two resources carry UCI in the four time units, the number of at least two resources carrying DCI and the number of at least two resources carrying DCI may be The number of UCI resources determines the priority of PUCCH and search space. For example, if the 4 time units include 2 resources that carry DCI and 3 resources that carry UCI, the priority of the PUCCH in the first time unit is higher than the priority of the search space, and the terminal device can send on the PUCCH UCI, without receiving DCI in this search space, but the present application is not so limited.

According to the above solution, whether it is necessary to continue to transmit the information on the overlapping resource is determined according to the transmission frequency of the information in the time unit before the time unit in which the resource overlap occurs, and the continuity of the information can be ensured.

Optionally, on H consecutive resources used to carry the first information, the first information is not received or not sent due to overlapping resources, and the terminal device determines that the priority of the first resource is higher than that of the second resource. priority.

That is, if the first resource does not carry or transmit the first information due to overlapping resources in H consecutive periods, the terminal device determines that the priority of the first resource in the first time unit is higher than that of the second resource , and send or receive the first information on the first resource. It can be avoided that the first information cannot be transmitted for a long time.

According to the above solution, in the case of overlapping resources, the terminal device and the network device determine to send or receive information corresponding to the resource on the high-priority resource according to the priority of the resource, so that the terminal device and the network device can be used for overlapping resources. A consensus can be reached on the information carried on the network, which can improve the reliability of communication.

The embodiment shown in FIG. 6 in this application may be implemented in combination with the embodiment shown in FIG. 2. For example, when the first resource and the second resource in the first time unit overlap at the third resource position, the terminal device and the The network device determines that the third resource is an uplink resource, a downlink resource or a flexible resource according to the format of the resource included in the first time unit, and if the indication information indicates that the third resource is an uplink resource, the third resource can only carry uplink resources Information, for example, the first resource is an uplink resource and the second resource is a downlink resource, and the terminal device and the network device determine to receive or send the first information on the first resource and not to receive or send the second information on the second resource. Alternatively, the first resource and the second resource are both uplink resources, and the terminal device and the network device determine to send information corresponding to the resource on the high-priority resource according to the priority of the first resource and the second resource. If the indication information indicates that the third resource is a downlink resource, for example, the first resource is an uplink resource and the second resource is a downlink resource, the terminal device and the network device determine to receive or send the second information on the second resource and not on the first resource. receive or send the first message on the Alternatively, the first resource and the second resource are both uplink resources, and the terminal device and the network device determine to send information corresponding to the resource on the high-priority resource according to the priority of the first resource and the second resource. If the third resource is a flexible resource, the terminal device and the network device determine, according to the priorities of the first resource and the second resource, to send information corresponding to the resource on the resource with high priority.

That is to say, the format of the time unit indicated by the indication information has the highest priority, and in the case of not conflicting with the format indicated by the indication information, the network device and the terminal device then determine the resource at the high priority according to the priority of the overlapping resources to send or receive information corresponding to the resource.

The wireless communication method provided by the embodiment of the present application further includes, when the second time interval between the uplink resource and the downlink resource is less than the first time interval, that is, less than the time interval required for the terminal device to switch between the receiving state and the sending state, It may be specified that the resources before the second time interval are advanced or the resources after the second time interval are delayed so that the resource interval between the uplink resources and the downlink resources is greater than or equal to the first time interval. Optionally, the resource interval after the resource advance or the resource delay may be specified as the third time interval. The third time interval is greater than or equal to the first time interval.

It should be noted that the resources before the second time interval may be uplink resources, the resources after the second time interval may be downlink resources, or the resources before the second time interval may be downlink resources, and the resources after the second time interval It may be an uplink resource, which is not limited in this application. Optionally, the protocol specifies the amount of time the resource is advanced and/or the amount of time the resource is delayed. Alternatively, the network device preconfigures the time amount of resource advance and/or resource delay to the terminal device through signaling.

Optionally, multiple time amounts (which may be referred to as the first candidate time amount set) for resource advance are specified by the protocol or pre-configured by the network (for example, configured through the radio resource RRC message or configured by the system message), and the network device passes the downlink control information DCI. Or the medium access control control element MAC CE indicates one of multiple time amounts for resource advance, that is, indicates one of the first candidate time amount sets. And/or, multiple time amounts (which may be referred to as the second candidate time amount set) for resource delay are specified by the protocol or pre-configured by the network (for example, configured through the radio resource RRC message or configured by the system message), and the network device uses the downlink control information The DCI or the medium access control control element MAC CE indicates one of the multiple time amounts of resource delay, i.e. indicates one of the second candidate time amount set. Optionally, the second time interval may be specified by a protocol or configured by the network device to the terminal device through signaling.

For example, as shown in Figure 10, the uplink resource PUCCH and the downlink resource search space are both semi-statically configured resources, and the interval between the PUCCH in a certain resource period and the search space in a certain resource period may be 3 symbols, and The first time interval may be 4 symbols, and the terminal device does not have enough time to switch from the transmitting state to the receiving state, so it cannot receive DCI in the search space. Therefore, when the resource interval between the uplink resources and the downlink resources is less than 4 symbols, the resources after the resource interval are delayed, so that the interval between the uplink resources and the downlink resources after the delay processing is equal to 5 symbols. Both the network device and the terminal device determine to delay the search space by 2 symbols, so that the interval between the PUCCH and the search space is equal to 5 symbols, then the network device can send DCI in the delayed search space, and the terminal device can DCI is received in the delayed search space, but the present application is not limited thereto.

Optionally, the network device may indicate whether to perform advance resources or delay resources by dynamically scheduling DCI or MAC CE.

For example, the network device pre-sends DCI to indicate that the resources after the resource interval are delayed, or indicate that the resources after the resource interval are not delayed, so that the terminal device determines whether to delay the resources after the resource interval according to the DCI indication, so that the terminal device and the network Devices reach a consensus, but this application is not limited to this.

According to the above solution, the terminal equipment and the network equipment advance or delay resources, so that the interval between the uplink resources and the downlink resources satisfies the time interval requirement of the uplink and downlink switching of HD-FDD, which can reduce the problems caused by the inability to switch the receiving state and the sending state. transmission delay.
