[0059] It should be noted that the communication systems to which the embodiments of the present application are applicable include but are not limited to third-generation systems (3G for short), long term evolution (LTE for short), fourth-generation systems (4G for short), fifth-generation (5G for short), new radio (NR for short), and future evolution systems or multiple communication convergence systems. Among them, the 5G system can be a non-standalone (NSA for short) 5G system or a standalone (SA for short) 5G system. The solution of the embodiments of the present application can also be applicable to various new communication systems in the future, such as 6G, 7G, etc.

[0060] The terminal in the embodiments of the present application may refer to various forms of user equipment (UE), access terminal, subscriber unit, subscriber 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 may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a future 5G network, or a terminal in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited thereto.

[0061] The network device in the embodiment of the present application may also be referred to as an access network device, for example, a base station (BS) (also referred to as a base station device), which 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 the base transceiver station (BTS), in the third-generation (3G) network, the device providing base station functions includes the node B (Node B), and in the fourth-generation (4G) network, the device providing base station functions includes the evolved node B (eNB). In wireless local area networks (WLAN), the device providing base station functions is the access point (AP). The device providing base station functions in NR is the next generation node base station (gNB) and the evolved node B (ng-eNB). The gNB and terminal devices communicate using NR technology, and the ng-eNB and terminal devices communicate using evolved universal terrestrial radio access (E-UTRA) technology. Both gNB and ng-eNB can be connected to the 5G core network. The network devices in the embodiments of the present application also include devices that provide base station functions in future new communication systems, etc.

[0062] The solution provided in the embodiments of the present application can be used in full-duplex scenarios. For example, it can be applied to CCFD scenarios. In a communication system supporting CCFD, time-domain and frequency-domain resources can be used for both uplink and downlink transmissions.

[0063] Currently, the rate matching mechanism in 5G can only be used for downlink Physical Downlink Shared Channel (PDSCH) transmission. The rate matching resources can be some protected transmissions, such as the synchronization reference signal of other cells, the Channel State Information Reference Signal (CSI-RS), or certain high-priority transmissions, which are transparent to the terminal.

[0064] In other words, there is currently no corresponding rate matching solution for simultaneous and same-frequency full-duplex technology.

[0065] An embodiment of the present invention provides a first information, which can be used to simultaneously indicate whether it is necessary to perform rate matching on the uplink time-frequency domain resource unit and the downlink time-frequency domain resource unit, filling the gap in the rate matching scheme for simultaneous frequency full-duplex technology and improving the effectiveness of the rate matching information indication.

[0066] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0067] Referring to Figure 1, Figure 1 is a schematic diagram of signaling interaction in a communication method according to an embodiment of the present invention. The method shown in Figure 2 can be executed by a network device, or can also be executed by a chip or chip module configured in the network device. The method shown in Figure 1 can include step S11.

[0068] Step S11: Send first information, where the first information is used to indicate whether to perform rate matching on the time-frequency domain resource unit in the simultaneous frequency full-duplex mode.

[0069] Simultaneous, same-frequency, full-duplex transmission can mean that the time-frequency resources for uplink and downlink transmissions are exactly the same, or that the time-frequency resources for uplink and downlink transmissions partially overlap. Because uplink and downlink data can use the same time-frequency resources, spectrum utilization can be multiplied compared to traditional half-duplex systems.

[0070] Furthermore, the uplink resource used for rate matching is the intersection of the physical uplink shared channel (PUSCH) and the uplink rate matching resource, and the downlink resource used for rate matching is the intersection of the physical downlink shared channel (PDSCH) and the downlink rate matching resource.

[0071] In an embodiment of the present invention, the uplink resource used for rate matching is the intersection between PUSCH and the uplink rate matching resource, and the downlink resource used for rate matching is the intersection between PDSCH and the downlink rate matching resource, so that after the first information is used for indication, rate matching can be implemented according to the indication.

[0072] 2 , which is a schematic diagram of an application scenario of rate matching in simultaneous and same-frequency full-duplex mode according to an embodiment of the present invention.

[0073] Taking the window area surrounded by dotted lines in Figure 2 as an example, the first window shows the situation where only downlink resources are used for downlink rate matching, the second window shows the situation where only uplink resources are used for uplink rate matching, and the third window shows the situation where uplink and downlink resources used for uplink and downlink rate matching overlap.

[0074] A time-frequency domain resource unit may refer to the granularity of time domain resources and frequency domain resources used for uplink and downlink transmission. For example, a time-frequency domain resource unit may be one or more resource blocks (RBs), one or more resource elements (REs), or a time-frequency domain resource unit may 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.

[0075] The first information may be information transmitted between the first communication device and the second communication device. In a specific implementation, the first information may be information carried in downlink control information (DCI), or may 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 embodiment of the present application may not limit the type of the first information.

[0076] In a specific implementation, the data sent by the network device needs to be rate matched to the time-frequency domain resource unit indicated by the first information.

[0077] The rate matching resources may include RB-level resources and RE-level resources. For example, the RB-level resources may be indicated by the rate matching indicator parameter field, and the RE-level resources may be indicated by the aperiodic zero power channel state information reference signal (ZP CSI-RS) trigger parameter field.

[0078] Furthermore, for resource block-level resources, the relevant rate matching process can be: first, the upper layer configures M rate matching resource groups (Rate Matching Pattern Group), each rate matching resource group can contain a group of resource block-level rate matching resources, and the rate matching indication in the first information contains M bits, each bit indicating whether the corresponding rate matching resource group is effective, that is, whether the data needs to be rate matched for the resources in the rate matching resource group.

[0079] In the embodiment of the present invention, the uplink resources in the rate matching resource group may be the intersection of the PUSCH and the uplink rate matching resources, and the downlink resources in the rate matching resource group may be the intersection of the PDSCH and the downlink rate matching resources.

[0080] For resource element (RE) level resources, the upper layer first configures N ZP CSI-RS resource sets, each of which contains multiple ZP CSI-RS resources. The ZP CSI-RS trigger in the first information can contain multiple bits, indicating that a certain aperiodic ZP CSI-RS resource set is effective, that is, whether the data needs to be rate matched to the resources in the aperiodic ZP CSI-RS resource set. The ZP CSI-RS trigger domain value of all 0s can, for example, indicate that no aperiodic ZP CSI-RS resource set is activated.

[0081] In a non-restrictive specific embodiment, the bit in the first information is 1 to indicate that the corresponding rate matching resource group is effective, that is, the data does not need to be rate matched with the resources in the rate matching resource group. Conversely, the bit is 0 to indicate that the corresponding rate matching resource group is not effective.

[0082] In an embodiment of the present invention, a first communication device (such as a network device) sends first information, and correspondingly, a second communication device (such as a terminal) receives the first information. The first information is used to indicate whether rate matching is to be performed on time-frequency domain resource units in a simultaneous frequency full-duplex mode. The first information can be used to indicate whether rate matching is required for uplink rate matching resources and downlink time-frequency domain resource units, thereby filling the gap in rate matching solutions for simultaneous frequency full-duplex technology and improving the effectiveness of rate matching information indication.

[0083] Furthermore, 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.

[0084] As a variation, each time-frequency domain resource unit may be indicated by two bits in the first information. Two bits may correspond to a specific time domain resource or frequency domain resource or time-frequency resource. For example, it may correspond to one or more resource blocks or one or more resource elements in the frequency domain, or to one or more OFDM symbols in the time domain, or to one or more time slots. Among them, one code point is used to indicate that downlink rate matching is required for the resource, another code point is used to indicate that uplink rate matching is required for the resource, and another code point is used to indicate that uplink and downlink rate matching is required for the resource at the same time. Optionally, a code point may also be used to indicate that uplink and downlink rate matching is not required for the resource.

[0085] In an embodiment of the present invention, the two bits are used to simultaneously indicate whether rate matching is required for the downlink time-frequency domain resource unit and whether rate matching is required for the uplink time-frequency domain resource unit, which can double the number of bits used to indicate the time-frequency domain resource unit. The technical solution of the present application uses the two bits to simultaneously indicate whether rate matching is required for the downlink time-frequency domain resource unit and whether rate matching is required for the uplink time-frequency domain resource unit, which can simultaneously indicate whether rate matching is required for the uplink time-frequency domain resource unit and the downlink time-frequency domain resource unit.

[0086] Example 1

[0087] The first information may be configured when the downlink rate matching resource is a resource block level resource.

[0088] 3 , which is a schematic diagram of a method for indicating resource block-level resources according to an embodiment of the present invention.

[0089] As shown in the figure, a single symbol can contain multiple resource blocks in the frequency domain, a single time slot can contain 14 symbols, and a single cycle can contain one or more time slot groups, wherein each time slot group contains a predefined number of time slots. For example, a single cycle shown in Figure 3 contains a single time slot group, and the single time slot group can contain 2 time slots.

[0090] Furthermore, the downlink rate matching resource is a resource block level resource, and the indication of the time-frequency domain resource unit by the first information is selected from one or more of the following: resource block level indication, symbol level indication and cycle level indication.

[0091] Specifically, respective indication information may be used for resource block level indication, symbol level indication, and cycle level indication, respectively, wherein part or all of the indication information uses the first information indication.

[0092] Furthermore, the first information may include a first bit map for indicating the time-frequency domain resource unit at the resource block level; wherein the number of bits in the first bit map is twice the number of resource blocks contained in a single symbol, and every two bits in the first bit map form a group, and each group of bits indicates the corresponding resource block.

[0093] Refer to Table 1, which is a schematic diagram showing the meaning of each bit of the first bitmap of the resource block level indication.

[0094] Table 1

[0095] As shown in Table 1, every two bits in the first bitmap form a group, each group of bits indicates the corresponding resource block, the first bit indicates whether the corresponding downlink resource block needs rate matching, and the second bit indicates whether the corresponding uplink resource block needs rate matching.

[0096] Alternatively, a 2-bit codepoint can be used to indicate the uplink and downlink rate matching status of a specific resource block. For example, the 2-bit codepoint consists of 4 codepoints: codepoint-1 indicates that only downlink rate matching is performed on the resource block, codepoint-2 indicates that only uplink rate matching is performed on the resource block, and codepoint-3 indicates that both uplink and downlink rate matching are performed on the resource block. Optionally, codepoint-4 can indicate that no uplink or downlink rate matching is performed on the resource block.

[0097] A code point can be used to represent the number corresponding to a character in a coded character set.

[0098] In a specific implementation of the embodiment of the present invention, the selected value of each bit can be from 0 to F, for example.

[0099] As shown in FIG3 , a single symbol may include 12 resource blocks. The number of bits in the first bitmap may be 24, with every two bits indicating one resource block.

[0100] It should be noted that, in the time domain, the first bitmap can be used as a unit for periodic repetitive application.

[0101] Furthermore, the first information may include a second bit map for symbol-level indication of the time-frequency domain resource unit; wherein the number of bits in the second bit map is twice the number of symbols contained in a single time slot, and every two bits in the second bit map form a group, and each group of bits indicates a corresponding single symbol.

[0102] Refer to Table 2, which is a schematic diagram showing the meaning of each bit of the second bitmap of the symbol level indication.

[0103] Table 2

[0104] As shown in Table 2, every two bits in the second bitmap form a group, each group of bits indicates the corresponding symbol, the first bit indicates whether the corresponding downlink symbol needs rate matching, and the second bit indicates whether the corresponding uplink symbol needs rate matching.

[0105] Alternatively, a 2-bit codepoint can be used to indicate the uplink and downlink rate matching status of a symbol. For example, the 2-bit codepoint consists of 4 codepoints: codepoint-1 indicates that only downlink rate matching is performed for the symbol, codepoint-2 indicates that only uplink rate matching is performed for the symbol, and codepoint-3 indicates that both uplink and downlink rate matching are performed for the symbol. Optionally, codepoint-4 can indicate that no uplink or downlink rate matching is performed for the symbol.

[0106] As shown in FIG. 3 , a single time slot may include 14 symbols. The number of bits in the second bitmap may be 28, with every two bits indicating one symbol.

[0107] It should be noted that, in the time domain, the second bitmap can be used as a unit for periodic repetitive application.

[0108] Furthermore, the first information includes a third bit map for period-level indication of the time-frequency domain resource unit, wherein 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 bit map is twice the number of time slot groups included in a single period, and every two bits in the third bit map form a group, and each group of bits indicates a corresponding single time slot group.

[0109] Refer to Table 3, which is a schematic diagram showing the meaning of each bit of the third bitmap of the cycle level indication.

[0110] Table 3

[0111] As shown in Table 3, every two bits in the third bitmap form a group, each group of bits indicates the corresponding time slot group, the first bit indicates whether the corresponding downlink time slot group needs to perform rate matching, and the second bit indicates whether the corresponding uplink time slot group needs to perform rate matching.

[0112] Alternatively, a 2-bit codepoint can be used to indicate the uplink and downlink rate matching status of a timeslot group. For example, the 2-bit codepoint consists of 4 codepoints: codepoint-1 indicates that the timeslot group performs only downlink rate matching, codepoint-2 indicates that the timeslot group performs only uplink rate matching, and codepoint-3 indicates that the timeslot group performs both uplink and downlink rate matching. Optionally, codepoint-4 can indicate that the timeslot group does not perform uplink and downlink rate matching. As shown in Figure 3, a single cycle can include a single timeslot group, each timeslot group can include two timeslots, and the number of bits in the third bitmap can be 2, with 2 bits indicating one timeslot group.

[0113] It should be noted that although FIG3 takes a single cycle including a single time slot group as an example, in a specific implementation, a single cycle may include multiple time slot groups, and the number of time slots included in each time slot group is not limited to 2 time slots.

[0114] It should be noted that, in the time domain, the third bitmap can be used as a unit for periodic repetition.

[0115] In an embodiment of the present invention, the downlink rate matching resource is a resource block-level resource, and the first information indicates the time-frequency domain resource unit selected from one or more of the following: a resource block-level indication, a symbol-level indication, and a cycle-level indication. The technical solution of the present application can simultaneously indicate whether rate matching is required for uplink time-frequency domain resource units and downlink time-frequency domain resource units through one or more of the resource block-level indication, the symbol-level indication, and the cycle-level indication, further improving the effectiveness of rate matching indication for resource block-level resources.

[0119] Specifically, respective indication information may be used for ZP CSI-RS resource-level indication, ZP CSI-RS symbol-level indication, ZP CSI-RS resource element-level indication, and CDM group-level indication, wherein part or all of the indication information uses the first information indication.

[0120] In a specific implementation, a resource mapping method 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.).

[0121] Furthermore, the first information includes ZP CSI-RS resource-level indication information, which is used to perform ZP CSI-RS resource-level indication on the time-frequency domain resource unit; wherein, the number of bits in the ZP CSI-RS resource-level indication information is twice the number of pre-configured 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.

[0122] The pre-configured ZP CSI-RS resources may be N ZP CSI-RS resource sets configured by a higher layer, and each ZP CSI-RS resource set may include multiple ZP CSI-RS resources.

[0123] 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 is required for the downlink time-frequency domain resource unit of the corresponding ZP CSI-RS resource, and whether rate matching is required for the uplink time-frequency domain resource unit of the corresponding ZP CSI-RS resource.

[0124] Furthermore, the first information may include ZP CSI-RS symbol-level indication information, which is used to perform 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 is required for the downlink time-frequency domain resource unit of the corresponding ZP CSI-RS symbol, and whether rate matching is required for the uplink time-frequency domain resource unit of the corresponding ZP CSI-RS symbol.

[0126] Furthermore, the ZP CSI-RS symbol to be indicated may be a ZP CSI-RS symbol starting from a time domain start position indicated by firstOFDMSymbolintimedomain or firstOFDMSymbolintimedomain2 for the time-frequency domain resource unit.

[0127] In the specific implementation of the embodiment of the present invention, two bits can be indicated one by one for the ZP CSI-RS symbols starting from the time domain starting position corresponding to firstOFDMSymbolintimedomain, 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 the downlink time-frequency domain resource unit of the corresponding ZP CSI-RS symbol needs to be rate matched, and the second bit is used to indicate whether the uplink time-frequency domain resource unit of the corresponding ZP CSI-RS symbol needs to be rate matched.

[0128] Furthermore, the first information may include ZP CSI-RS resource element level indication information, which is used to perform 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.

[0129] Every two bits in the ZP CSI-RS resource element level indication information form a group, and each group of bits can be used to indicate whether rate matching is required for the downlink time-frequency domain resource unit of the corresponding ZP CSI-RS resource element, and whether rate matching is required for the uplink time-frequency domain resource unit of the corresponding ZP CSI-RS resource element.

[0130] The ZP CSI-RS resource element to be indicated may be indicated through appropriate signaling.

[0131] Furthermore, the ZP CSI-RS resource elements to be indicated are all ZP CSI-RS resource elements indicated by firstOFDMSymbolintimedomain or firstOFDMSymbolintimedomain2 for the time-frequency domain resource unit.

[0132] In a specific embodiment, all ZP CSI-RS resource elements indicated for the time-frequency domain resource unit may be ZP CSI-RS RE 2, ZP CSI-RS RE 3, ZP CSI-RS RE 6, and ZP CSI-RS RE 7, and the ZP CSI-RS resource elements to be indicated may be ZP CSI-RS RE 2, ZP CSI-RS RE 3, ZP CSI-RS RE 6, and ZP CSI-RS RE 7, instead of ZP CSI-RS RE 0 to ZP CSI-RS RE 7.

[0133] In the specific implementation of the embodiment of the present invention, all ZP CSI-RS resource elements indicated by firstOFDMSymbolintimedomain or firstOFDMSymbolintimedomain2 for the time-frequency domain resource unit can be indicated by two bits one by one. For example, the first bit is used to indicate whether the downlink time-frequency domain resource unit of the corresponding ZP CSI-RS resource element needs to be rate matched, and the second bit is used to indicate whether the uplink time-frequency domain resource unit of the corresponding ZP CSI-RS resource element needs to be rate matched.

[0135] Each CDM group may have a preset CDM type and parameters thereof. By using two bits as a group, each group of bits indicates a corresponding CDM group, and the CDM group may be used as a unit for distinction.

[0136] Refer to Table 4, which is a schematic diagram showing the meaning of each bit of the fourth bitmap of the CDM group-level indication.

[0137] Table 4

[0138] As shown in Table 4, every two bits in the fourth bitmap form a group, each group of bits indicates the corresponding CDM group, and the first bit is used to indicate whether it is necessary to perform rate matching on the downlink time-frequency domain resource unit of the time-frequency domain resource unit encoded by the corresponding CDM group, and whether it is necessary to perform rate matching on the uplink time-frequency domain resource unit of the time-frequency domain resource unit encoded by the corresponding CDM group.

[0139] Alternatively, a 2-bit codepoint is used to indicate the uplink and downlink rate matching status of the CDM group. For example, the 2-bit codepoint consists of 4 codepoints: codepoint-1 indicates that the CDM group performs only downlink rate matching, codepoint-2 indicates that the CDM group performs only uplink rate matching, and codepoint-3 indicates that the CDM group performs both uplink and downlink rate matching. Optionally, codepoint-4 can indicate that the CDM group does not perform uplink and downlink rate matching.

[0141] Furthermore, the first information can be indicated by downlink control information DCI; wherein, in the simultaneous frequency full-duplex mode, the downlink rate matching resources and uplink rate matching resources of the time-frequency domain resource unit share the indication of the DCI.

[0142] Specifically, in a simultaneous and same-frequency full-duplex mode, the downlink rate matching resources and uplink rate matching resources of the time-frequency domain resource unit can share the DCI indication. At this time, it is more likely to cause the 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 it is necessary to perform rate matching on the uplink time-frequency domain resource unit and the downlink time-frequency domain resource unit.
