[0058] It should be noted that the communication systems applicable to the embodiments of the present application include, but are not limited to, the third-generation system (3G), the long term evolution (LTE) system, the fourth-generation system (4G), the fifth-generation system (5G), the New Radio (NR) system, as well as future evolved systems or various communication convergence systems. Among them, the 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The solutions of the embodiments of the present application can also be applicable to various future new communication systems, such as 6G, 7G, etc.

[0059] The terminal in the embodiments of the present application may refer to various forms of user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), remote station, remote terminal, mobile device, user terminal, terminal equipment, wireless communication device, user agent or user device. The terminal can also be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication function, computing device or other processing devices connected to a wireless modem, vehicle-mounted device, wearable device, terminal in the future 5G network or terminal in the future evolved Public Land Mobile Network (PLMN), etc. The embodiments of the present application are not limited thereto.

[0060] The network device in the embodiments of this application can also be referred to as an access network device. For example, it can be a base station (abbreviated as BS) (which can also be referred to as base station equipment). A network device is a device deployed in a Radio Access Network (RAN) to provide wireless communication functions. For example, in the second-generation (2G) network, the device providing base station functions includes a base transceiver station (BTS); in the third-generation (3G) network, the device providing base station functions includes Node B; in the fourth-generation (4G) network, the device providing base station functions includes an evolved Node B (eNB); in a wireless local area network (WLAN), the device providing base station functions is an access point (AP); in NR, the device providing base station functions is a next generation node base station (gNB), and a next-generation evolved Node B (ng-eNB). Among them, NR technology is used for communication between the gNB and the terminal device, and Evolved Universal Terrestrial Radio Access (E-UTRA) technology is used for communication between the ng-eNB and the terminal device. Both the gNB and the ng-eNB can be connected to the 5G core network. The network device in the embodiments of this application also includes devices that provide base station functions in future new communication systems, etc.

[0061] The solution provided by the embodiments of this application can be used in a full-duplex scenario. Exemplarily, it can be applied to a CCFD scenario. In a communication system that supports CCFD, time-domain and frequency-domain resources can be used for uplink transmission and downlink transmission simultaneously.

[0062] Currently, the rate matching mechanism in 5G can only be used for the transmission of the Physical Downlink Shared Channel (PDSCH). The resources for rate matching can be some protected transmissions, such as synchronization reference signals of other cells, Channel State Information Reference Signals (CSI-RS), or some high-priority transmissions, etc. These are transparent to the terminal.

[0063] In other words, there is currently no corresponding rate matching scheme for the simultaneous co-frequency full-duplex technology.

[0064] An embodiment of the present invention provides a first piece of information, which can be used to simultaneously indicate whether rate matching needs to be performed on the uplink time-frequency resource unit and the downlink time-frequency resource unit, filling the gap in the rate matching scheme for the simultaneous co-frequency full-duplex technology and improving the indication effectiveness of the rate matching information.

[0065] To make the above objects, features, and beneficial effects of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings.

[0066] Refer to Figure 1 , Figure 1 which is a signaling interaction schematic diagram of a communication method in an embodiment of the present invention. Figure 2 The method shown can be executed by a network device, or alternatively, can be executed by a chip or chip module configured in the network device. Figure 1 The method shown may include step S11.

[0067] Step S11: Send a first piece of information, where the first piece of information is used to indicate whether rate matching is to be performed on the time-frequency resource unit in the simultaneous co-frequency full-duplex mode.

[0068] Among them, simultaneous co-frequency full-duplex transmission may mean that the time-frequency resources of the uplink transmission and the downlink transmission are completely the same, or the time-frequency resources of the uplink transmission and the downlink transmission partially overlap. Since the uplink data and the downlink data can use the same time-frequency resources, the spectrum utilization rate can be doubled compared to the traditional half-duplex system.

[0069] Further, the uplink resource for rate matching is the intersection between the Physical Uplink Share Channel (PUSCH) and the uplink rate matching resource, and the downlink resource for rate matching is the intersection between the Physical Downlink Share Channel (PDSCH) and the downlink rate matching resource.

[0070] In the embodiment of the present invention, the uplink resource for rate matching is the intersection between the PUSCH and the uplink rate matching resource, and the downlink resource for rate matching is the intersection between the PDSCH and the downlink rate matching resource, so that after the indication is made using the first piece of information, rate matching can be implemented according to the indication.

[0071] Refer to Figure 2 , Figure 2 which is a schematic diagram of an application scenario of rate matching in the simultaneous co-frequency full-duplex mode in an embodiment of the present invention.

[0072] Taking Figure 2 the window area enclosed by the dashed line as an example, the first window shows the case where there is only downlink resource for downlink rate matching, the second window shows the case where there is only uplink resource for uplink rate matching, and the third window shows the case where the uplink and downlink resources for uplink and downlink rate matching overlap.

[0073] The time-frequency domain resource unit can refer to the granularity of the time domain resource and the frequency domain resource for uplink transmission and downlink transmission. For example, the time-frequency domain resource unit can be one or more resource blocks (RBs), one or more resource elements (REs), or the time-frequency domain resource unit can be a time-frequency resource that occupies 12 subcarriers in the frequency domain and a preset number of symbols in the time domain, but is not limited thereto.

[0074] The first information can be the information transmitted between the first communication device and the second communication device. In a specific implementation, the first information can be the information carried in the downlink control information (DCI), or it can also be carried in other appropriate information in the future, such as high-layer signaling, such as radio resource control (RRC) or media access control layer control element (MAC-CE). The embodiments of the present application do not limit the type of the first information.

[0075] In a specific implementation, the data sent by the network device needs to perform rate matching on the time-frequency domain resource unit indicated by the first information.

[0076] Among them, the rate matching resources can include RB-level resources and RE-level resources. For example, the RB-level resources can be indicated by the rate matching indicator parameter field, and the RE-level resources can be indicated by the aperiodic zero-power channel state information reference signal (ZP CSI-RS) trigger parameter field.

[0077] Further, for resource block-level resources, the related rate matching process may be as follows: First, the higher layer configures M rate matching pattern groups, and each rate matching pattern group may include a set of resource block-level rate matching resources. The rate matching indication in the first information includes M bits, and each bit indicates whether the corresponding rate matching pattern group is effective, that is, whether data needs to perform rate matching on the resources in the rate matching pattern group.

[0078] In an embodiment of the present invention, the uplink resources in the rate matching pattern group may be the intersection between the PUSCH and the uplink rate matching resources, and the downlink resources in the rate matching pattern group may be the intersection between the PDSCH and the downlink rate matching resources.

[0079] For resource element (RE)-level resources, first, the higher layer configures N ZP CSI-RS resource sets, and each ZP CSI-RS resource set includes multiple ZP CSI-RS resources. The ZP CSI-RS trigger in the first information may include multiple bits, indicating that a certain aperiodic ZP CSI-RS resource set is effective, that is, whether data needs to perform rate matching on the resources in the aperiodic ZP CSI-RS resource set. For example, when the ZP CSI-RS trigger threshold is all 0, it may indicate that no aperiodic ZP CSI-RS resource set is activated.

[0080] In a non-limiting specific implementation, a bit of 1 in the first information is used to indicate that the corresponding rate matching pattern group is effective, that is, data does not need to perform rate matching on the resources in the rate matching pattern group. On the contrary, a bit of 0 is used to indicate that the corresponding rate matching pattern group is not effective.

[0081] In an embodiment of the present invention, the first communication device (such as a network device) sends the first information. Correspondingly, the second communication device (such as a terminal) receives the first information. The first information is used to indicate whether to perform rate matching on time-frequency domain resource units in the simultaneous co-frequency full-duplex mode. It may be possible to use the first information to indicate whether rate matching is required for uplink rate matching resources and downlink time-frequency domain resource units, filling the gap in the rate matching scheme for the simultaneous co-frequency full-duplex technology and improving the effectiveness of rate matching information indication.

[0082] Further, the two bits are used to simultaneously indicate whether rate matching is required for downlink time-frequency domain resource units and whether rate matching is required for uplink time-frequency domain resource units.

[0083] As a variant, each time-frequency domain resource unit can be indicated by two bits in the first information. The two bits can correspond to a specific time domain resource or frequency domain resource or time-frequency resource. For example, it can correspond to one or more resource blocks or one or more resource elements in the frequency domain, or one or more OFDM symbols in the time domain, or one or more time slots. Among them, one code point is used to indicate that downlink rate matching needs to be performed on the resource, another code point is used to indicate that uplink rate matching needs to be performed on the resource, and there is another code point used to indicate that both uplink and downlink rate matching need to be performed on the resource. Optionally, one code point can also be used to indicate that uplink and downlink rate matching is not required for the resource.

[0084] In the embodiment of the present invention, the two bits are used to simultaneously indicate whether rate matching needs to be performed on the downlink time-frequency domain resource unit and whether rate matching needs to be performed on the uplink time-frequency domain resource unit, which can double the number of bits used to indicate the time-frequency domain resource unit. Through the technical solution of this application, the two bits are used to simultaneously indicate whether rate matching needs to be performed on the downlink time-frequency domain resource unit and whether rate matching needs to be performed on the uplink time-frequency domain resource unit, which can simultaneously indicate whether rate matching needs to be performed on the uplink time-frequency domain resource unit and the downlink time-frequency domain resource unit.

[0085] Embodiment 1

[0086] The first information can be configured in the case where the downlink rate matching resource is a resource block-level resource.

[0087] Refer to Figure 3 , Figure 3 is a schematic diagram of an indication method for a resource block-level resource in an embodiment of the present invention.

[0088] As shown in the figure, a single symbol can include multiple resource blocks in the frequency domain, a single time slot can include 14 symbols, and a single period can include one or more time slot groups. Among them, each time slot group includes a predefined number of time slots, such as Figure 3 shown that a single period includes a single time slot group, and this single time slot group can include 2 time slots.

[0089] Furthermore, the downlink rate matching resource is a resource block-level resource, and the indication of the time-frequency domain resource unit in the first information is selected from one or more of the following: resource block-level indication, symbol-level indication, and period-level indication.

[0090] Specifically, respective indication information can be used for resource block-level indication, symbol-level indication, and period-level indication, among which part or all of the indication information is indicated by the first information.

[0091] Further, the first information may include a first bitmap for resource block-level indication of the time-frequency domain resource units; wherein, the number of bits in the first bitmap is twice the number of resource blocks included in a single symbol, and every two bits in the first bitmap form a group, and each group of bits indicates a corresponding resource block.

[0092] Referring to Table 1, Table 1 is a schematic diagram showing the meanings of the respective bits of the first bitmap for resource block-level indication.

[0093] Table 1

[0094]

[0095]

[0096] As shown in Table 1, every two bits in the first bitmap form a group, and each group of bits indicates a corresponding resource block. The first bit indicates whether rate matching is required for the corresponding downlink resource block, and the second bit indicates whether rate matching is required for the corresponding uplink resource block.

[0097] Alternatively, the uplink and downlink rate matching status of a specific resource block is indicated by a 2-bit codepoint. For example, the 2 bits consist of 4 codepoints. Codepoint-1 indicates that only downlink rate matching is performed for this resource block, codepoint-2 indicates that only uplink rate matching is performed for this resource block, and codepoint-3 indicates that both uplink and downlink rate matching are performed for this resource block. Optionally, codepoint-4 may indicate that no uplink and downlink rate matching is performed for this resource block.

[0098] Wherein, a codepoint can be used to represent the number corresponding to a character in a coded character set.

[0099] In a specific implementation manner of the embodiment of the present invention, the value selection of each bit can be, for example, from 0 to F.

[0100] As Figure 3 shown, a single symbol may include 12 resource blocks, the number of bits in the first bitmap may be 24, and every two bits indicate a resource block.

[0101] It should be noted that in the time domain, the first bitmap can be repeatedly applied periodically as a unit.

[0102] Furthermore, the first information may include a second bitmap for symbol-level indication of the time-frequency domain resource unit; wherein, the number of bits in the second bitmap is twice the number of symbols included in a single time slot, and every two bits in the second bitmap form a group, with each group of bits indicating a corresponding single symbol.

[0103] Referring to Table 2, Table 2 is used to show a schematic diagram of the meanings of each bit of the second bitmap for symbol-level indication.

[0104] Table 2

[0105]

[0106] As shown in Table 2, every two bits in the second bitmap form a group, with each group of bits indicating a corresponding symbol. The first bit indicates whether rate matching is required for the corresponding downlink symbol, and the second bit indicates whether rate matching is required for the corresponding uplink symbol.

[0107] Alternatively, the uplink and downlink rate matching status of the symbol is indicated by a 2-bit codepoint. For example, the 2 bits consist of 4 codepoints. Codepoint-1 indicates that only downlink rate matching is performed for this symbol, codepoint-2 indicates that only uplink rate matching is performed for this symbol, and codepoint-3 indicates that both uplink and downlink rate matching are performed for this symbol. Optionally, codepoint-4 may indicate that no uplink and downlink rate matching is performed for this symbol.

[0108] As Figure 3 shown, a single time slot may include 14 symbols, the number of bits in the second bitmap may be 28, and every two bits indicate a symbol.

[0109] It should be noted that in the time domain, the second bitmap can be applied in a periodic and repetitive manner as a unit.

[0110] Furthermore, the first information includes a third bitmap for cycle-level indication of the time-frequency domain resource unit. The time-frequency domain resource unit includes multiple time slot groups, and each time slot group includes a predefined number of time slots; wherein, the number of bits in the third bitmap is twice the number of time slot groups included in a single cycle, and every two bits in the third bitmap form a group, with each group of bits indicating a corresponding single time slot group.

[0111] Referring to Table 3, Table 3 is used to show a schematic diagram of the meanings of each bit of the third bitmap for cycle-level indication.

[0112] Table 3

[0113]

[0114] As shown in Table 3, in the third bit map, every two bits form a group, and each group of bits indicates the corresponding time slot group. The first bit indicates whether rate matching is required for the corresponding downlink time slot group, and the second bit indicates whether rate matching is required for the corresponding uplink time slot group.

[0115] Alternatively, the uplink and downlink rate matching status of the time slot group is indicated by a 2-bit codepoint. For example, the 2 bits consist of 4 codepoints. Codepoint-1 indicates that only downlink rate matching is performed for this time slot group, codepoint-2 indicates that only uplink rate matching is performed for this time slot group, and codepoint-3 indicates that both uplink and downlink rate matching are performed for this time slot group. Optionally, codepoint-4 can indicate that no uplink and downlink rate matching is performed for this time slot group. As Figure 3 shown, a single period can contain a single time slot group, each time slot group can contain 2 time slots, the number of bits in the third bit map can be 2, and 2 bits indicate one time slot group.

[0116] It should be noted that although Figure 3 a single period containing a single time slot group is taken as an example, in actual implementation, a single period can contain multiple time slot groups, and the number of time slots contained in each time slot group is not limited to 2 time slots.

[0117] It should be noted that in the time domain, the third bit map can be used as a unit for periodic repeated application.

[0118] In the embodiments of the present invention, the downlink rate matching resource is a resource block-level resource, and the indication of the first information for the time-frequency domain resource unit is selected from one or more of the following: resource block-level indication, symbol-level indication, and period-level indication. Through one or more of the resource block-level indication, symbol-level indication, and period-level indication in the technical solution of the present application, it is possible to simultaneously indicate whether rate matching is required for the uplink time-frequency domain resource unit and the downlink time-frequency domain resource unit, and further improve the effectiveness of rate matching indication for resource block-level resources.

[0119] Embodiment 2

[0120] The first information can be configured in the case where the downlink rate matching resource is a resource element-level resource.

[0121] Further, the downlink rate matching resource is a resource at the resource element level, and the indication of the time-frequency resource unit by the first information is selected from one or more of the following: ZP CSI-RS resource level indication, ZP CSI-RS symbol level indication, ZP CSI-RS resource element level indication, and code division multiplexing (CDM) group level indication.

[0122] Specifically, the ZP CSI-RS resource level indication, ZP CSI-RS symbol level indication, ZP CSI-RS resource element level indication, and CDM group level indication can be respectively performed using their respective indication information, where part or all of the indication information is indicated by the first information.

[0123] In a specific implementation, the resource mapping of N non-zero power (NZP) CSI-RS can be adopted, and the resource block where its time-frequency resource is located can be determined through appropriate signaling (such as frequencydomainallocation, firstOFDMSymbolintimedomain, firstOFDMSymbolintimedomain2, etc.).

[0124] Furthermore, the first information includes ZP CSI-RS resource level indication information for performing ZP CSI-RS resource level indication on the time-frequency resource unit; where the number of bits in the ZP CSI-RS resource level indication information is twice the number of preconfigured ZP CSI-RS resources, and every two bits in the ZP CSI-RS resource level indication information form a group, and each group of bits indicates the corresponding ZP CSI-RS resource.

[0125] Among them, the preconfigured ZP CSI-RS resources can be N ZP CSI-RS resource sets configured by a higher layer, and each ZP CSI-RS resource set can include multiple ZP CSI-RS resources.

[0126] Every two bits in the ZP CSI-RS resource level indication information form a group, and each group of bits can be used to indicate whether rate matching needs to be performed on the downlink time-frequency resource unit of the corresponding ZP CSI-RS resource, and whether rate matching needs to be performed on the uplink time-frequency resource unit of the corresponding ZP CSI-RS resource.

[0127] Furthermore, the first information may include ZP CSI-RS symbol-level indication information for performing ZP CSI-RS symbol-level indication on the time-frequency domain resource unit; wherein, the number of bits in the ZP CSI-RS symbol-level indication information is twice the number of ZP CSI-RS symbols to be indicated, and every two bits in the ZP CSI-RS symbol-level indication information form a group, and each group of bits indicates the corresponding ZP CSI-RS symbol; the every two bits are used to indicate whether rate matching needs to be performed on the downlink time-frequency domain resource unit of the corresponding ZP CSI-RS symbol, and whether rate matching needs to be performed on the uplink time-frequency domain resource unit of the corresponding ZP CSI-RS symbol.

[0128] Wherein, the ZP CSI-RS symbols to be indicated may be indicated by appropriate signaling.

[0129] Furthermore, the ZP CSI-RS symbols to be indicated may be ZP CSI-RS symbols starting from the time domain start position indicated by firstOFDMSymbolintimedomain or firstOFDMSymbolintimedomain2 for the time-frequency domain resource unit.

[0130] In the specific implementation of the embodiment of the present invention, two-bit indications may be performed one by one on the ZP CSI-RS symbols starting from the time domain start positions corresponding to firstOFDMSymbolintimedomain and firstOFDMSymbolintimedomain2, so as to distinguish the corresponding ZP CSI-RS symbols in the time domain. For example, the first bit is used to indicate whether rate matching needs to be performed on the downlink time-frequency domain resource unit of the corresponding ZP CSI-RS symbol, and the second bit is used to indicate whether rate matching needs to be performed on the uplink time-frequency domain resource unit of the corresponding ZP CSI-RS symbol.

[0131] Furthermore, the first information may include ZP CSI-RS resource element-level indication information for performing ZP CSI-RS resource element-level indication on the time-frequency domain resource unit; wherein, the number of bits in the ZP CSI-RS resource element-level indication information is twice the number of ZP CSI-RS resource elements to be indicated, and every two bits in the ZP CSI-RS resource element-level indication information form a group, and each group of bits indicates the corresponding ZP CSI-RS resource element.

[0132] In the ZP CSI-RS resource element level indication information, every two bits form a group. Each group of bits can be used to indicate whether rate matching needs to be performed on the downlink time-frequency resource unit of the corresponding ZP CSI-RS resource element, and whether rate matching needs to be performed on the uplink time-frequency resource unit of the corresponding ZP CSI-RS resource element.

[0133] Among them, the ZP CSI-RS resource elements to be indicated can be indicated by appropriate signaling.

[0134] Furthermore, the ZP CSI-RS resource elements to be indicated are all the ZP CSI-RS resource elements indicated by firstOFDMSymbolintimedomain or firstOFDMSymbolintimedomain2 for the time-frequency resource unit.

[0135] In a specific embodiment, all the ZP CSI-RS resource elements indicated for the time-frequency resource unit can be ZP CSI-RS RE 2, ZP CSI-RS RE 3, ZP CSI-RS RE 6, ZP CSI-RS RE 7. The ZP CSI-RS resource elements to be indicated can be ZP CSI-RS RE 2, ZP CSI-RS RE 3, ZP CSI-RS RE 6, ZP CSI-RS RE 7, rather than ZP CSI-RS RE 0 to ZP CSI-RS RE 7.

[0136] In the specific implementation of the embodiments of the present invention, two-bit indications can be made one by one for all the ZP CSI-RS resource elements indicated by firstOFDMSymbolintimedomain or firstOFDMSymbolintimedomain2 for the time-frequency resource unit. For example, the first bit is used to indicate whether rate matching needs to be performed on the downlink time-frequency resource unit of the corresponding ZP CSI-RS resource element, and the second bit is used to indicate whether rate matching needs to be performed on the uplink time-frequency resource unit of the corresponding ZP CSI-RS resource element.

[0137] Furthermore, the first information includes CDM group-level indication information for indicating the CDM group level of the time-frequency domain resource unit; wherein, the number of bits in the CDM group-level indication information is twice the number of pre-configured CDM groups, and every two bits in the CDM group-level indication information form a group, and each group of bits indicates the corresponding CDM group; the every two bits are used to indicate whether rate matching needs to be performed on the downlink time-frequency domain resource unit of the time-frequency domain resource unit encoded with the corresponding CDM group, and whether rate matching needs to be performed on the uplink time-frequency domain resource unit of the time-frequency domain resource unit encoded with the corresponding CDM group.

[0138] Wherein, each CDM group may have a preset CDM type and its parameters. By using every two bits as a group, and each group of bits indicates the corresponding CDM group, it can be distinguished in units of CDM groups.

[0139] Referring to Table 4, Table 4 is used to represent a schematic diagram of the meanings of each bit of the fourth bit map for CDM group-level indication.

[0140] Table 4

[0141]

[0142] As shown in Table 4, every two bits in the fourth bit map form a group, and each group of bits indicates the corresponding CDM group. The first bit is used to indicate whether rate matching needs to be performed on the downlink time-frequency domain resource unit of the time-frequency domain resource unit encoded with the corresponding CDM group, and whether rate matching needs to be performed on the uplink time-frequency domain resource unit of the time-frequency domain resource unit encoded with the corresponding CDM group.

[0143] Alternatively, the indication of the uplink and downlink rate matching status of the CDM group is achieved through a 2-bit codepoint. For example, the 2 bits consist of 4 codepoints. Codepoint-1 indicates that the CDM group only performs downlink rate matching, codepoint-2 indicates that the CDM group only performs uplink rate matching, and codepoint-3 indicates that the CDM group performs both uplink and downlink rate matching.

[0146] Specifically, in a simultaneous co-frequency full-duplex mode, the downlink rate matching resource and the uplink rate matching resource of the time-frequency domain resource unit may share the indication of the DCI. At this time, it is more likely to have a problem of invalid DCI indication. By adopting the solution of the embodiment of the present invention, the first information can be better used to simultaneously indicate whether rate matching needs to be performed on the uplink time-frequency domain resource unit and the downlink time-frequency domain resource unit.
