[0039] The technical solutions described in some embodiments of the present application can be applicable to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced long term evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-U) system, NR on unlicensed spectrum (NR-U) system, Non-Terrestrial Networks (NTN) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (Wireless Fidelity) system. Fidelity, WiFi), fifth-generation communication (5th-Generation, 5G) system, cellular Internet of Things system, cellular passive Internet of Things system, and can also be applied to subsequent evolution systems of 5G NR system, and can also be applied to 6G and subsequent evolution systems.

[0040] It should be understood that in some embodiments of the present application, "5G" may also be referred to as "5G NR" or "NR".

[0041] It should be understood that in the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0042] In the embodiments of the present application, "predefined" can be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (for example, a terminal device and a network device). The present application does not limit the specific implementation method. For example, predefined can refer to information defined in a protocol.

[0043] In the embodiments of the present application, "protocol" may refer to a standard protocol in the field of communications, for example, it may include an LTE protocol, a NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0044] Next, the downlink data transmission method is introduced:

[0045] The communication system includes terminal devices and network devices. Taking the terminal device as a UE and the network device as a base station as an example, the communication system generally supports the following two downlink data transmission modes:

[0046] (1) The UE receives the downlink control signaling sent by the base station and receives downlink data transmission based on the parameters in the downlink control signaling. This scheduling method is called dynamic scheduling. The advantage of dynamic scheduling is that it can determine the transmission parameters based on the real-time traffic volume and physical channel conditions, resulting in high transmission efficiency. The UE first receives the downlink control signaling and receives the downlink data channel or sends the uplink data channel based on the parameters indicated in the downlink control signaling. However, the UE needs to perform blind detection on the downlink control signaling, and its reception complexity is high. In addition, the processing delay at the receiving end (UE) includes demodulating the downlink control signaling and demodulating the downlink data. When there are a lot of downlink control signaling and downlink data, the processing delay at the receiving end is high.

[0047] (2) The UE receives high-level signaling from the base station and receives downlink data transmission based on the parameters in the high-level signaling. This is called semi-persistent scheduling (SPS) in LTE and NR systems. For UEs with periodic arrival, constant traffic volume, and stable transmission conditions (e.g., no rapid movement), using semi-persistent scheduling can reduce the downlink control signaling overhead in the system and simplify the reception processing at the receiving end (UE).

[0048] Fig. 1 shows a schematic diagram of a communication system 100 provided by an exemplary embodiment of the present application. The communication system 100 includes a first communication device and a second communication device.

[0049] In some embodiments, the first communication device is a terminal device 110, and the second communication device is a network device 120; or, the first communication device is a network device 120, and the second communication device is a terminal device 110. The embodiments of the present application are not limited to this, and the first communication device is a terminal device 110 and the second communication device is a network device 120 as an example for illustration.

[0050] The terminal device 110 in this application is also called user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, and user device.

[0051] The network device 120 in the present application provides wireless communication functions, and the network device 120 includes but is not limited to: an evolved Node B (eNB), a radio network controller (RNC), a node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a home evolved Node B, or a home node B, HNB), a baseband unit (BBU), an access point (AP) in a Wi-Fi system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It can also be a next generation node B (gNB) or a transmission point (TRP or TP) in a 5G mobile communication system, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DPU).

[0052] The terminal device 110 and the network device 120 communicate with each other via some air interface technology, such as a Uu interface.

[0053] Exemplarily, there are two communication scenarios between the terminal device 110 and the network device 120: uplink communication scenario and downlink communication scenario. Uplink communication refers to the terminal device 110 sending a signal to the network device 120; downlink communication refers to the network device 120 sending a signal to the terminal device 110.

[0054] The technical solutions provided in the embodiments of the present application can be applied to various communication systems, such as: GSM system, CDMA system, WCDMA system, GPRS, LTE system, LTE-A system, LTE frequency division duplex (FDD) system, LTE TDD system, UMTS, Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5G mobile communication system, NR system, NR system evolution system, LTE-U system, NR-U system, NTN system, non-NTN system, WLAN, Wi-Fi, cellular Internet of Things system, cellular passive Internet of Things system, and can also be applied to subsequent evolution systems of 5G NR system, and can also be applied to B5G, 6G and subsequent evolution systems.

[0055] In some embodiments of the present application, "NR" may also be referred to as a 5G NR system or a 5G system. A 5G mobile communication system may include a non-standalone (NSA) and / or standalone (SA) network.

[0056] The technical solutions provided in the embodiments of the present application can also be applied to machine type communication (MTC), long term evolution technology for machine-to-machine communication (LTE-M), device-to-device (D2D) network, machine-to-machine (M2M) network, Internet of Things (IoT) network or other networks. Among them, the IoT network can include, for example, the Internet of Vehicles. Among them, the communication mode in the Internet of Vehicles system is collectively referred to as vehicle to other devices (Vehicle to X, V2X, X can represent anything), for example, the V2X can include: vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, vehicle to pedestrian communication (V2P) or vehicle to network (V2N) communication, etc.

[0057] In certain communication scenarios, several information exchanges between communication devices have agreed-upon characteristic information, such as data arrival time, data volume, data transmission direction, data type, etc. These several information exchanges can be considered as an information group.

[0058] Figure 2 shows a schematic diagram of an information group provided by an exemplary embodiment of the present application. In a data transmission service, multiple information groups (also referred to as channel groups) are included between the receiving end (terminal device) and the sending end (network device), such as a first information group and a second information group. Each information group includes one or more information or channels. Taking the first information group as an example, downlink information 1, downlink information 2, and downlink information 3 represent information sent by the network device and received by the terminal device. The information type or information content of different downlink information is different or the same. Uplink information 1 and uplink information 2 represent information sent by the terminal device to the network device. The information type or information content of different uplink information is different or the same.

[0059] Among them, the time interval between the starting point of the first information group and the starting point of the second information group is T0, the time interval between the starting point of downlink information 1 and the starting point of downlink information 2 is t1, the time interval between the starting point of downlink information 2 and the starting point of uplink information 1 is t2, the time interval between the starting point of uplink information 1 and the starting point of downlink information 3 is t3, the time interval between the starting point of downlink information 3 and the starting point of uplink information 2 is t4, the time interval between the starting point of uplink information 1 and the starting point of downlink information 1 is T1, the time interval between the starting point of downlink information 3 and the starting point of downlink information 1 is T2, and the time interval between the starting point of uplink information 2 and the starting point of downlink information 1 is T3.

[0060] In some communication scenarios, communication between network devices and end devices occurs in groups. The groups may have periodicity or be completely random. While the transmission characteristics between groups are similar, the effective information content they carry is different. This means that the information content in different groups is not repeated transmissions of the same information.

[0061] If a communication device can obtain the characteristic information of an information group, subsequent scheduling can be performed based on the characteristic information of the information group after the transmission service is initiated. In other words, subsequent transmission and reception operations only need to be based on a small amount of scheduling signaling. This helps reduce signaling overhead in the communication system, improves the transmission efficiency of the communication system, and also helps reduce the implementation complexity of communication equipment and reduce the power consumption of communication equipment.

[0062] FIG3 shows a flow chart of a method for transmitting indication information provided by an exemplary embodiment of the present application. The method is executed by a first communication device, which may be a terminal device or a network device, and includes:

[0063] Step 310: Receive first indication information, where the first indication information is used to indicate a scheduling parameter of at least one information group;

[0064] Each information group includes at least one information or channel. In some embodiments, the information group includes at least one information or channel monitored or transmitted over a period of time. In some embodiments, the first indication information is used to indicate scheduling parameters for at least one information group. The scheduling parameters include: monitoring parameters for control information or control channels, and / or transmission parameters for data information or data channels.

[0065] In summary, the method provided in this embodiment receives first indication information that indicates scheduling parameters for an information group, which includes at least one information or channel. This method performs scheduling at the granularity of "one information group," saving scheduling signaling overhead and improving the transmission efficiency of the communication system. Because scheduling signaling is reduced, the overhead of the terminal device's blind detection control channel can also be reduced, thereby reducing the terminal device's power consumption.

[0066] FIG4 shows a flow chart of a method for transmitting indication information provided by an exemplary embodiment of the present application. The method is executed by a second communication device, which may be a network device or a terminal device, and includes:

[0067] Step 410: Send first indication information, where the first indication information is used to indicate a scheduling parameter of at least one information group;

[0068] Each information group includes at least one information or channel. In some embodiments, the information group includes at least one information or channel monitored or transmitted over a period of time. In some embodiments, the first indication information is used to indicate scheduling parameters for at least one information group. The scheduling parameters include: monitoring parameters for control information or control channels, and / or transmission parameters for data information or data channels.

[0069] In summary, the method provided in this embodiment receives first indication information that indicates scheduling parameters for an information group, which includes at least one information or channel. This method performs scheduling at the granularity of "one information group," saving scheduling signaling overhead and improving the transmission efficiency of the communication system. Because scheduling signaling is reduced, the overhead of the terminal device's blind detection control channel can also be reduced, thereby reducing the terminal device's power consumption.

For example, the monitoring of a control information group is activated only during the time period when downlink data scheduling exists, thereby reducing the terminal device's blind detection of the Physical Downlink Control Channel (PDCCH) and reducing the power consumption of the terminal device.

In addition, the end time can also be indicated by a combination of the start time and the time length. The end time of the monitoring control channel can be indicated by an absolute time, or by the number of monitoring opportunities, or by a combination of the number of monitoring opportunities and the time interval between adjacent monitoring opportunities.

[0110] In some embodiments, the monitoring parameters of a control information group indicated by the first indication information are a subset of monitoring parameters configured for the control information or control channel. Exemplarily, the monitoring parameters of a control information group indicated by the first indication information are a true subset of monitoring parameters pre-configured for the control information or control channel. The pre-configured monitoring parameters may be periodic monitoring parameters or aperiodic monitoring parameters.

[0111] In some embodiments, the monitoring parameters indicated by the first indication information are a subset of pre-configured monitoring parameters, and may include at least one of the following:

[0112] The monitoring time corresponding to the time parameter of the control information group is a portion of the monitoring time corresponding to the time parameter pre-configured for the control information or control channel;

[0113] The search space of the control information group is a portion of the search space pre-configured for control information or control channels;

[0114] A search space group of a control information group is a part of a search space group pre-configured for control information or control channels;

[0115] A control resource set of a control information group is a portion of a control resource set pre-configured for control information or a control channel;

[0116] A monitoring opportunity of a control information group is a part of the monitoring opportunities pre-configured for control information or control channels;

[0117] The control information format of the control information group is a part of the control information format pre-configured for the control information or control channel;

[0118] The control information size of the control information group is a portion of the control information size pre-configured for the control information or control channel;

[0119] The candidate control channels of the control information group are part of the candidate control channels pre-configured for control information or control channels.

[0120] In some embodiments, taking the control information as DCI and the control channel as PDCCH as an example, the first indication information is used to indicate monitoring parameters of a PDCCH transmission group. The PDCCH transmission group includes at least one DCI or PDCCH or PDCCH monitoring opportunity.

[0121] In some embodiments, the monitoring parameters include at least one of the following: a time parameter for monitoring PDCCH; a search space or search space group for monitoring PDCCH; a control resource set (CORESET) for monitoring PDCCH; a listening opportunity parameter for monitoring the control channel; a DCI format to be monitored; a DCI size to be monitored; and a PDCCH candidate to be monitored.

[0122] In some embodiments, the time parameter includes at least one of the following: a start time for monitoring PDCCH; an end time for monitoring PDCCH; or a duration for monitoring PDCCH. The monitoring opportunity parameter includes at least one of the following: a start monitoring opportunity for monitoring PDCCH; an end monitoring opportunity for monitoring PDCCH; or a number of monitoring opportunities for monitoring PDCCH.

[0123] Exemplary reference Figure 5, the terminal device receives the first indication information, which is used to indicate the monitoring parameters of a PDCCH transmission group. The first indication information is used to instruct the terminal device to monitor the PDCCH within a period of time, the start time of the period is time t1, the end time is time t2, and the time length is L. Among them, the indication method of time t1 can be an offset value relative to the time domain position (starting position or ending position) where the first indication information is located. If the offset value is expressed in time units, the subcarrier spacing corresponding to the time unit is the same as the subcarrier spacing corresponding to the PDCCH, or the subcarrier spacing corresponding to the time unit is the same as the subcarrier spacing corresponding to the first indication information. The time length L can be represented by M time units, or it can be represented by N PDCCH monitoring opportunities.

[0124] In another possible design, a first indication message is used to instruct the terminal device to monitor the PDCCH starting from time t1, and then another first indication message is used to indicate time t2 or time length L.

[0125] In some embodiments, the first indication information is used to indicate a monitoring parameter of a PDCCH transmission group, where the monitoring parameter is a subset of pre-configured monitoring parameters configured for the PDCCH.

[0126] Exemplary reference Figure 6, assuming that the terminal device receives RRC signaling in advance, and the RRC signaling pre-configures the periodic monitoring parameters of PDCCH for the terminal device, and the period of adjacent PDCCH monitoring opportunities in the periodic monitoring parameters is C1; then the terminal device receives the first indication information, and the first indication information is used to indicate the monitoring parameters within a period of time, and the period of adjacent PDCCH monitoring opportunities in the monitoring parameters is C2, which is twice C1, and other monitoring parameters remain unchanged compared with the periodic monitoring parameters.

[0127] Referring to Figure 7, it is assumed that the terminal device receives RRC signaling in advance, and the RRC signaling pre-configures the periodic monitoring parameters of PDCCH for the terminal device, and the periodic monitoring parameters need to monitor DCI format 1 and DCI format 2 within each PDCCH monitoring opportunity; then the terminal device receives the first indication information, and the first indication information is used to indicate the monitoring parameters within a period of time. The monitoring parameters only need to monitor DCI format 1 within each PDCCH monitoring opportunity, and the other monitoring parameters remain unchanged compared to the periodic monitoring parameters.

[0128] Referring to Figure 8 for example, it is assumed that the terminal device receives RRC signaling in advance, and the RRC signaling pre-configures the periodic monitoring parameters of the PDCCH for the terminal device, and the periodic monitoring parameters need to monitor the PDCCH candidates associated with the search space sets 1 to 3 within each PDCCH monitoring opportunity; then the terminal device receives the first indication information, and the first indication information is used to indicate the monitoring parameters within a period of time, and the monitoring parameters only need to monitor the PDCCH candidates associated with the search space set 1 within each PDCCH monitoring opportunity, and the other monitoring parameters remain unchanged compared with the periodic monitoring parameters.

[0129] To sum up, the method provided in the embodiment of the present application indicates the monitoring parameters of a control information group through a first indication information, and the monitoring parameters are a subset of the pre-configured monitoring parameters, so that the monitoring workload corresponding to the monitoring parameters of this group of control information groups is less than the monitoring workload corresponding to the pre-configured monitoring parameters, and outside the time indicated by the first indication information, the terminal may not monitor the control information, thereby enabling the terminal device in this group of control information groups to save more power.

[0130] In an optional embodiment based on the above embodiment, the control information in the control information group indicated by the first indication information may include at least one of the first control information and the second control information;

[0131] First control information, used to indicate at least one transmission parameter of at least one piece of data information or a data channel;

[0132] The second control information is used to indicate at least one of the following information of at least one data information or data channel: correction information, supplementary information, and cancellation information.

[0133] The first control information may be any one of complete control information, baseline control information, reference control information, complete DCI, baseline DCI, reference DCI, complete DCI format, baseline DCI format, and reference DCI format; and the second control information may be any one of differential control information, modified control information, supplemental control information, cancellation control information, differential DCI, modified DCI, supplemental DCI, cancellation DCI, differential DCI format, modified DCI format, supplemental DCI format, and cancellation DCI format. The first control information indicates most transmission parameters or common transmission parameters for at least one data message or data transmission, and the second control information indicates a small portion or non-common transmission parameters for at least one data message or data channel.

[0134] It should be noted that the “at least one data information or data channel” indicated by the second control information may be all or part of the “at least one data information or data channel” indicated by the first control information.

[0135] To summarize, the method provided in this embodiment schedules at least one data information or data channel through the "complete + differential" method of "first control information + second control information". The complete first control information is used to indicate most of the transmission parameters or common transmission parameters, and the differential second control information is used to indicate a small part of different or non-shared transmission parameters for one or more data information or data channels, thereby realizing efficient scheduling of a group of irregular data transmissions, reducing the required control information overhead, saving signaling resources, and reducing air interface overhead.

[0136] In some embodiments, the correction information in the second control information is used to correct one or more transmission parameters of at least one transmission parameter; the supplementary information is used to supplement other transmission parameters other than at least one transmission parameter; and the cancellation information is used to cancel at least one data information or data channel.

[0137] In some embodiments, the data information or data channel includes at least one of uplink data information, downlink data information, uplink control information, and downlink control information.

[0138] In some embodiments, the transmission parameters include at least one of the following: parameters related to time domain resources, parameters related to frequency domain resources, parameters related to modulation, transmission parameters related to coding, parameters related to the amount of information, parameters related to reference signals, parameters related to reliability requirements, and parameters related to delay requirements.

[0139] In some embodiments, the transmission parameters include at least one of the following: time domain resources; frequency domain resources; spatial resources; Hybrid Automatic Repeat Request (HARQ) process (number); HARQ feedback related information; Modulation and Coding Scheme (MCS); Transport Block Size (TBS); transmission mode; amount of information; and redundant version.

[0140] In some embodiments, the transmission mode refers to dynamic scheduling transmission of data information or data channels, semi-static scheduling transmission, single TRP transmission or multiple TRP transmission, etc. For example, SPS, Configured Grant (CG), PUSCH+PDSCH, etc.

[0141] In some embodiments, the first control information indicates n transmission parameters, where n is a positive integer, including time domain resources, frequency domain resources, spatial resources, HARQ process number, HARQ feedback, MCS, TBS, transmission mode, information size, and redundancy version. The second control information modifies at least one of the n transmission parameters. This modification can be performed on the first data information or data channel. For example, if the first control information indicates an MCS of 5, the second control information modifies the MCS to 4.

[0142] In some embodiments, the first control information indicates n transmission parameters in the redundancy version, where n is a positive integer, including time domain resources, frequency domain resources, spatial resources, HARQ process number, HARQ feedback, MCS, TBS, transmission mode, information size, and the redundancy version. The second control information supplements the m transmission parameters in addition to the n transmission parameters. This supplementation can be performed for the first data information or data channel. For example, the first control information does not indicate the HARQ process number, but the second control information supplements it.

[0143] In some embodiments, the first control information indicates multiple data information or data channels, and the second control information cancels the first data information or data channel among the multiple data information or data channels. The first data information or data channel is a certain data information or data channel, or the remaining multiple data information or data channels after the second control information.

[0144] Taking the example of the control information group including a set of monitoring opportunities for second control information, the second control information is associated with at least one piece of data information or data channel, where the at least one piece of data information or data channel is all or part of the data transmission indicated by the first control information. The association between the second control information and the at least one piece of data information or data channel can be explicitly or implicitly indicated.

[0145] In the case of explicit indication, the second control information carries: identification information of at least one data information or data channel, and the at least one data information or data channel is the data transmission associated with the second control information. Optionally, the identification information of the at least one data information or data channel includes at least one of the following: the service cell index where the at least one data information or data channel is located; the partial bandwidth (BandWidth Part, BWP) index where the at least one data information or data channel is located; the time domain unit where the at least one data information or data channel is located; the frequency domain unit where the at least one data information or data channel is located; the sequence number of the at least one data information or data channel in the time domain unit; the uplink indication corresponding to the at least one data information or data channel; the downlink indication corresponding to the at least one data information or data channel. At this time, based on the explicit indication of the second control information, the terminal device can determine that the at least one data information or data channel is associated with the second control information.

[0146] The use of explicit indication can improve the scheduling flexibility of the second control information, that is, one second control information can modify and / or supplement transmission parameters for one, several, or all subsequent data transmissions, or cancel data transmission.

[0147] In the case of implicit indication, the identification information of the first data information or the data channel may be indicated by at least one of the DCI format of the second control information, the scrambling sequence, and the resource corresponding to the second control information.

[0148] Optionally, at least one data information or data channel associated with the second control information includes: the data information or data channel closest to the second control information; or, the data information or data channel closest to the time domain position corresponding to the second control information; or, the next data information or data channel closest to the second control information; or, the nearest data information or data channel no earlier than the first processing time after the end position of the second control information; or, on the activated BWP of the first service cell, the data information or data channel closest to the end position of the second control information; or, on the activated BWP of the first service cell, the data information or data channel closest to the end position of the second control information, and the nearest data information or data channel meets the processing time corresponding to the terminal.

[0149] Optionally, the at least one data information or data channel associated with the second control information includes: the n data information or data channels closest to the second control information; or the n data information or data channels closest to the time domain position corresponding to the second control information; or the subsequent n data information or data channels closest to the second control information; or the n data information or data channels closest to the first processing time after the end position of the second control information; or the n data information or data channels closest to the end position of the second control information on the activated BWP of the serving cell; or the n data information or data channels closest to the end position of the second control information on the activated BWP of the serving cell, and the n data information or data channels closest to the end position of the second control information, and the n data information or data channels closest to the end position of the second control information on the activated BWP of the serving cell, and the n data information or data channels all meet the processing time corresponding to the terminal device. Wherein, n is a positive integer. For example, the start time of the at least one data information or data channel associated with the second control information is the Mth time slot after the end of the first indication information.

[0150] Among them, the first processing time is the time required for the terminal device to process the control information and / or prepare the data information. In some embodiments, the terminal expects that the start time of the data information or data channel closest to the second control information is no earlier than the first processing time after the end time of the second control information. It should be noted that the above-mentioned start or start position can be an absolute time, or it can be the start time or end time of the first time domain unit occupied by the control information or data information; the above-mentioned end or end position can be an absolute time, or it can be the start time or end time of the last time domain unit occupied by the control information or data information.

[0151] By adopting the implicit indication method, the payload size of the second control information can be further reduced. The second control information only needs to carry limited information, thus saving transmission resources of the control channel.

[0152] The resources of the second control information include at least one of time domain resources, frequency domain resources, and monitoring opportunities. There are two ways to determine the resources corresponding to the second control information:

[0153] Method 1: instructed by the first instruction information;

[0154] The first indication information includes an indication field for indicating the resources corresponding to the second control information, and the indication field may be one or more. Exemplarily, the indication fields are used to indicate: at least one of the starting position, length, and ending position of the time domain resources corresponding to the second control information; at least one of the starting position, length, and ending position of the frequency domain resources corresponding to the second control information; at least one of the position and / or number of monitoring opportunities, search space set, control resource set, and PDCCH candidates corresponding to the second control information, etc.

[0155] As shown in Figure 9, a complete DCI pre-configures multiple semi-static data messages or data channels: data transmission 11, data transmission 12, data transmission 13, data transmission 14, and so on. When the multiple semi-static data messages or data channels are uplink transmissions, they are transmitted based on periodic uplink data channel transmission opportunities (such as PUSCH opportunities); when the multiple semi-static data messages or data channels are downlink transmissions, they are transmitted based on periodic downlink data channel transmission opportunities (such as PDSCH opportunities). Other transmission parameters or most transmission parameters of the multiple data messages or data channels are the same, such as information type, transmission channel, TBS size, etc.

[0156] Then the terminal device receives the first indication information, which is used for monitoring parameters of multiple PDCCH listening opportunities (such as listening opportunities 21, 22, 23, 24 and 25 in the figure), and multiple PDCCH listening opportunities are used to monitor differential DCI (that is, the second control information). Assuming that a differential DCI is listened to in PDCCH listening opportunity 21, it is determined according to the implicit indication principle that the data transmission closest to the differential DCI is the data transmission on transmission opportunity 12, and the differential DCI is used to modify, supplement or cancel the data transmission on transmission opportunity 12; and assuming that another differential DCI is listened to in PDCCH listening opportunity 23, it is determined according to the implicit indication principle that the data transmission closest to the differential DCI is the data transmission on transmission opportunity 13, and the differential DCI is used to modify, supplement or cancel the data transmission on transmission opportunity 13.

[0157] Method 2: Associated with the time-frequency resources used to transmit data information / channels.

[0158] In some embodiments, the time-frequency resource corresponding to the monitoring opportunity of the control information / channel is determined based on the time-frequency resource corresponding to the transmission opportunity of the data information / channel. Optionally, the at least one data information or data channel is a semi-static data transmission or a portion of a semi-static data transmission. The time-frequency resource corresponding to the transmission opportunity of the data information / channel is indicated by the first indication information or pre-configured.

[0159] In some embodiments, the resources corresponding to the second control information are located before the time-frequency resources of the data information or data channel corresponding to the second control information, and there is a first offset between the starting position of the resources corresponding to the second control information and the starting position of the time-frequency resources of the data information or data channel corresponding to the second control information.

[0160] In some embodiments, the resource corresponding to the second control information is determined based on the time-frequency resource of the data information or data channel corresponding to the second control information. The resource corresponding to the second control information has a one-to-one relationship, a one-to-many relationship, or a many-to-one relationship with the time-frequency resource of the data information or data channel corresponding to the second control information.

[0161] For example, the resource corresponding to the second control information is a PDCCH monitoring opportunity, and the time-frequency resource corresponding to data transmission is a PDSCH / PUSCH opportunity:

[0162] If each PDSCH / PUSCH opportunity corresponds to multiple PDCCH monitoring opportunities, it is a one-to-many relationship. For example, each PDSCH / PUSCH opportunity corresponds to two PDCCH monitoring opportunities, and the two PDCCH monitoring opportunities are used to monitor differential DCI.

[0163] If multiple PDSCH / PUSCH opportunities correspond to one PDCCH monitoring opportunity, then the relationship is many-to-one. For example, the time domain positions of three PDSCH / PUSCH opportunities correspond to one PDCCH monitoring opportunity, and one PDCCH monitoring opportunity is used to monitor differential DCI, which can modify, supplement, or cancel at least one data information or data channel on the three PDSCH / PUSCH opportunities.

[0164] If each PDCCH monitoring opportunity corresponds to multiple PDSCH / PUSCH opportunities, it is a one-to-many relationship; if multiple PDCCH monitoring opportunities correspond to one PDSCH / PUSCH opportunity, it is a many-to-one relationship.

[0165] Multiple PDCCH monitoring opportunities correspond to multiple PDSCH / PUSCH opportunities, forming a many-to-many relationship. For example, the time domain positions of three PDSCH / PUSCH opportunities correspond to two PDCCH monitoring opportunities. These two PDCCH monitoring opportunities are used to monitor differential DCI, which can modify, supplement, or cancel at least one data information or data channel on the three PDSCH / PUSCH opportunities.

[0166] As shown in Figure 10, there are semi-static PDSCH and PUSCH that have been activated. Among them, adjacent PDSCH opportunities and / or PUSCH opportunities are based on a period of P, and PDSCH opportunities and PUSCH opportunities appear alternately. At the same time, the first indication information indicates a set of differential DCI (that is, the second control information) listening opportunities, and these differential DCI listening opportunities are in front of each PDSCH / PUSCH opportunity, for example, before a certain offset. According to a one-to-one correspondence, each PDSCH / PUSCH opportunity corresponds to a PDCCH listening opportunity. These PDCCH listening opportunities are used to monitor differential DCI, and differential DCI is used to correct or supplement the transmission parameters of at least one PDSCH / PUSCH located after the differential DCI, or, differential DCI is used to cancel at least one PDSCH / PUSCH located after the differential DCI.

[0167] In a case where the resources corresponding to a second control information are associated with the time-frequency resources corresponding to multiple data information or data channels, the second control information can also explicitly or implicitly indicate at least one data information or data channel among the multiple data information or data channels to correct the transmission parameters or supplement the transmission parameters or cancel the transmission for the at least one data information or data channel.

[0168] In summary, when a data information group is part of semi-static data information or a data channel, the second control information can be used to modify or supplement all or part of the transmission parameters for a portion of the data transmission in the data information group, or to cancel a portion of the data information or data channel. Because the second control information only needs to carry limited information, its payload is small. This ensures scheduling flexibility while conserving control channel transmission resources.

[0169] For type 2: data information group

[0170] The data information group includes: at least one data information or a data channel or a transmission opportunity of a data channel.

[0171] In some embodiments, the first indication information is used to indicate a scheduling parameter of at least one information group. One or more information groups in the at least one information group are data information groups. The scheduling parameters of the one or more information groups include transmission parameters of the data information groups.

[0172] The first indication information is used to indicate transmission parameters of one or more data information groups. Each data information group includes: at least one data information or a data channel or a transmission opportunity of a data channel.

[0173] In some embodiments, at least one data information group includes at least two types of data information or data channels or transmission opportunities for data channels. In this embodiment, the different types of data information or data channels differ in at least one of the following factors: transmission channel, information content, information format, information size, reliability requirements, latency requirements, etc.

[0174] As shown in Figure 11, the first indication information is used to activate semi-static PDSCH and PUSCH. Adjacent PDSCH opportunities and / or PUSCH opportunities have a period of P, and PDSCH opportunities and PUSCH opportunities appear alternately. PDSCH and PUSCH belong to different transport channels: PDSCH is used to transmit downlink data, and PUSCH is used to transmit uplink data.

[0175] As shown in Figure 12, the first indication information is used to activate the semi-static first and second PDSCHs. Adjacent first and / or second PDSCH opportunities have a period of P, and the first and second PDSCH opportunities appear alternately. PDSCH and PUSCH belong to different transmission channels, and the first and second PDSCH opportunities are used to transmit downlink data with different information amounts, formats, and contents.

[0176] In summary, by transmitting at least two types of data information or data channels in one data information group, different from traditional semi-static transmission, efficient scheduling can be achieved in certain communication scenarios.

[0177] For example, the telemedical device and the server always use a "request-response" combined uplink and downlink communication mode. When the data size of each request and response is foreseeable, one or several first indication messages can be used to indicate the transmission parameters for a longer period of time to the telemedical device and the server, saving control signaling resources while ensuring lower latency (because no intermediate control signaling is required, or only less differential control signaling is required, the interval between two adjacent data information or data channels can be shorter).

[0178] For example, a server sends a command to a robotic arm, which is carried on the PDSCH. The command requires the robotic arm to respond after a certain period of time, and the response is carried on the PUSCH. The first instruction indicates the transmission parameters of a data group, which includes at least two pieces of information: PDSCH and PUSCH.

[0179] For type three: mixed information group

[0180] In some embodiments, the first indication information is used to indicate scheduling parameters of at least one information group. One or more of the at least one information group is a mixed information group. The scheduling parameters of the one or more information groups include transmission parameters of data information or a data channel, and monitoring parameters of control information or a control channel.

[0181] The mixed information group includes: at least one data information or data channel or data channel transmission opportunity, and at least one control information or control channel or control channel monitoring opportunity.

[0182] The first indication information is used to indicate monitoring parameters and / or transmission parameters of one or more mixed information groups.

[0183] The data information or data channel includes at least one of the following: uplink data information, downlink data information, sidelink data information, uplink data channel, downlink data channel, sidelink data channel, uplink shared information, downlink shared information, sidelink shared information, uplink shared channel, downlink shared channel, sidelink shared channel.

[0184] The control information or control channel includes at least one of the following: uplink control information, downlink control information, sidelink control information, uplink control channel, downlink control channel, and sidelink control channel.

[0185] In some embodiments, the information type of the control information or control channel includes at least one of the following: configuration information; authorization information; allocation information; downlink control signaling; physical layer control signaling; high-layer signaling; wireless resource control signaling; medium access control signaling; uplink control signaling; feedback response information; channel state information; scheduling request; cache status report; uplink channel demodulation reference information.

[0186] In some embodiments, the feedback response information includes at least one of the following: response, negative response.

[0187] In some embodiments, the channel state information includes at least one of the following: channel state information, channel quality indication, precoding indication, and rank indication.

[0188] As shown in Figure 13, the first indication information is used to activate semi-static PDSCH and PUSCH. Among them, adjacent PDSCH opportunities and / or PUSCH opportunities are periodic with P, and PDSCH opportunities and PUSCH opportunities appear alternately. At the same time, the first indication information also indicates a set of differential DCI (that is, the second control information) listening opportunities, and these differential DCI listening opportunities are located at a certain offset before each PDSCH / PUSCH opportunity. Therefore, the first indication information indicates a mixed information group, which includes: PDSCH, PUSCH, PDCCH three types of information or multiple information of channels.

[0189] This embodiment can simultaneously indicate the transmission parameters of data information / channels and the monitoring parameters of control information / channels through the first indication information. It can use one or more first indication information to indicate the transmission parameters and / or monitoring parameters for a longer period of time to the first communication device, saving control signaling resources while ensuring lower latency (because no intermediate control signaling is required, or only less differential control signaling is required, so the interval between two adjacent data information or data channels can be shorter).

[0190] For example, in a virtual reality scenario, the XR terminal first reports its posture information to the server via the PUCCH. The server then renders the virtual reality environment based on this posture information and transmits the rendered environment image to the XR terminal via the PDSCH. The first indication information then indicates the transmission parameters of a mixed information group, which includes at least two pieces of information: PUCCH and PDSCH.

[0191] It should be noted that in the above-mentioned embodiments, adjacent information transmissions in each information group are equally spaced, or adjacent information transmissions of the same type are equally spaced for illustration. However, the embodiments of the present application are not limited to this. Adjacent information transmissions in an information group may be unequally spaced, or adjacent information transmissions of the same type may be unequally spaced. That is, an information group includes: at least two non-periodic information. By supporting non-periodic information groups, efficient scheduling in more complex communication scenarios can be adapted. Even if multiple information between two communication devices is not periodic, efficient centralized scheduling can be performed using the first indication information.

[0192] It should also be noted that one or a group of first indication information may indicate multiple information groups, and the multiple information groups include at least one of a control information group, a data information group, and a mixed information group.

[0193] First instruction information:

[0194] The first indication information is used to indicate scheduling parameters of one or more information groups, where the scheduling parameters include: monitoring parameters of control information or control channels, and / or transmission parameters of data information or data channels. The first indication information may be RRC signaling, MAC CE signaling, or DCI. The first indication information includes at least one of the following three designs:

[0195] Design 1:

[0196] The first indication information includes a first index value associated with a set of scheduling parameters for an information group. The correspondence between the first index value and the set of scheduling parameters is predefined by a protocol or preconfigured by a network device. The scheduling parameters include monitoring parameters of a control channel and / or transmission parameters of a data channel.

[0197] In some embodiments, the network device pre-configures a correspondence between multiple index values ​​and multiple groups of scheduling parameters for the terminal device. Each group of scheduling parameters includes one or more scheduling parameters. The types of scheduling parameters in different groups of scheduling parameters may be the same or different; the number of scheduling parameters in different groups of scheduling parameters may be the same or different. Table 1 exemplifies the above correspondence.

[0198] Table 1

[0199] Table 1 is merely an example of a possible design. In different embodiments, the types and quantities of the above scheduling parameters may vary and are not described in detail here.

[0200] If the first indication information includes the index value 00, then a set of scheduling parameters indicating an information group includes: time domain resource 1, frequency domain resource 1, information format 1, reliability requirement 1, and delay requirement 1.

[0201] Through the first design, the overhead of the first indication information is relatively small, and only a few bits are needed to indicate a set of scheduling parameters.

[0202] Design 2:

[0203] The first indication information includes at least one indication field. Each of the at least one indication field is used to indicate a scheduling parameter for an information group; different indication fields indicate different types of scheduling parameters. For example, the first indication information includes a time domain resource indication field, a frequency domain resource indication field, an information format indication field, a reliability indication field, a delay requirement indication field, and the like.

[0204] In some embodiments, an information group includes at least two information types, and the first indication information also includes: an information type indication field, which is used to indicate an information type (data information or control information or listening opportunity or data channel or control channel or transmission opportunity).

[0205] In some embodiments, each information type indication field corresponds to a set of scheduling parameter indication fields, and different information type indication fields correspond to different sets of scheduling parameter indication fields. For example, the first indication information includes: (data channel 1, time domain resource indication field 1, frequency domain resource indication field 1, information format indication field 1, reliability indication field 1, delay requirement indication field 1), (data channel 2, time domain resource indication field 2, frequency domain resource indication field 2, information format indication field 2, reliability indication field 2, delay requirement indication field 2).

[0206] In some embodiments, each information type indication field corresponds to a group of scheduling parameter indication fields, and different information type indication fields correspond to different groups of scheduling parameter indication fields. Furthermore, the first indication information further includes: scheduling parameter indication fields shared by different information types. For example, the first indication information includes: (data channel 1, time domain resource indication field 1, frequency domain resource indication field 1), (data channel 2, time domain resource indication field 2, frequency domain resource indication field 2), a shared information format indication field, a shared reliability indication field, and a shared delay requirement indication field.

[0207] In some embodiments, an information group includes at least two information or channels, and the first indication information further includes: an information transmission indication field, where the information transmission indication field is used to indicate at least one information or channel.

[0208] In some embodiments, each information transmission indication field corresponds to a group of scheduling parameter indication fields, and different information transmission indication fields correspond to different groups of scheduling parameter indication fields. For example, the first indication information includes: (the first information, time domain resource indication field 1, frequency domain resource indication field 1, information format indication field 1, reliability indication field 1, and delay requirement indication field 1), (the second information, time domain resource indication field 2, frequency domain resource indication field 2, information format indication field 2, reliability indication field 2, and delay requirement indication field 2), and (the third to fifth information, time domain resource indication field 3, frequency domain resource indication field 3, information format indication field 3, reliability indication field 3, and delay requirement indication field 3).

[0209] In some embodiments, each information transmission indication field corresponds to a set of scheduling parameter indication fields, and different information transmission indication fields correspond to different sets of scheduling parameter indication fields. Furthermore, the first indication information further includes: scheduling parameter indication fields shared by different information transmissions. For example, the first indication information includes: (the first information, time domain resource indication field 1, frequency domain resource indication field 1), (subsequent information transmissions other than the first information, time domain resource indication field 2, frequency domain resource indication field 2), a shared information format indication field, a shared reliability indication field, and a shared delay requirement indication field.

[0210] Through the second design, the scheduling parameters of each dimension can be indicated more precisely, and the indication flexibility is higher.

[0211] Design 3:

[0212] The first indication information is used to indicate the scheduling parameters of the first x pieces of information or channels among the n pieces of information or channels, where n is a positive integer greater than 1, and x is a positive integer not greater than n. The scheduling parameters of the first x pieces of information or channels can be indicated using the above-mentioned Design 1 and / or Design 2.

[0213] All or part of the scheduling parameters of the other information or channels except the first x information or channels among the n information or channels are determined based on at least one of the following methods:

[0214] Method 1: Scheduling parameters of the first x messages or channels;

[0215] For example, all or part of the scheduling parameters of the other information or channels except the first x information or channels among the n information or channels are consistent with the scheduling parameters of the first x information or channels or are generated according to the same rule.

[0216] For example, the channel state changes little over a period of time, and the uplink and downlink channels are different. Therefore, the channel states of multiple uplink and downlink transmissions within this period can be considered the same or similar, and can share at least one scheduling parameter such as the same or related frequency domain resources, MCS, and redundancy version. In this case, the scheduling parameters of subsequent data channels can be obtained based on the scheduling parameters of the first x (e.g., the first) data channels indicated by the first indication information.

[0217] Method 2: the second indication information carried by at least one of the first x pieces of information or channels;

[0218] For example, all or part of the first x information or channels, or one of the information or channels, may carry the second indication information. The second indication information is used to indicate all or part of the scheduling parameters of the other information or channels. Optionally, the second indication information may be designed in a manner similar to Design 1 or Design 2.

[0219] Method 3: Scheduling parameters pre-defined by the protocol;

[0220] All or part of the scheduling parameters for information or channels other than the first x information or channels among the n information or channels are determined according to the scheduling parameters predefined in the communication protocol. For example, part of the scheduling parameters for information or channels other than the first x information or channels among the n information or channels are determined according to the scheduling parameters predefined in the communication protocol.

[0221] Mode 4: The second index value carried by the first indication information is associated with a set of scheduling parameters;

[0222] The corresponding relationship between the second index value and a set of scheduling parameters is predefined by the protocol or preconfigured by the network device. The corresponding relationship can be similarly referred to in Table 1 and will not be described in detail.

[0223] For example, the first indication information carries scheduling parameters for the first x pieces of information or channels, and a second index value. The second index value is associated with a set of scheduling parameters, and a portion of scheduling parameters for other pieces of information or channels is determined based on the second index value. The remaining scheduling parameters remain consistent with, or are generated according to the same rule as, the scheduling parameters for the first x pieces of information or channels.

[0224] Mode 5: The indication field of the first indication information is used to configure at least one scheduling parameter for other information or channels;

[0225] For example, in addition to indicating the scheduling parameters of the first x pieces of information or channels, the first indication information also carries at least one indication field, which is used to configure at least one scheduling parameter for other information or channels. In some embodiments, an information group includes at least two information types, and the first indication information further includes: at least two information type indication fields, each corresponding to one information type. Each information type indication field corresponds to a group of scheduling parameter indication fields, and different information type indication fields correspond to different groups of scheduling parameter indication fields.

[0226] In some embodiments, an information group includes at least two information types, and the first indication information further includes: at least two information type indication fields, each information type indication field is used to indicate an information type (data information or control information or data channel or control channel). Each information type indication field corresponds to an index value or a group of scheduling parameter indication fields, and different information type indication fields correspond to respective index values ​​or a group of scheduling parameter indication fields. For example, the first indication information includes: (data channel 1, first index value 1), (control channel 1, first index value 2), (data channel 2, first index value 3).

[0227] Design three balances indication flexibility and signaling overhead, minimizing the signaling overhead of the first indication message while ensuring flexibility. Furthermore, the three designs described above can be freely combined to design the first indication message appropriate for the current information group based on the transmission characteristics of the information group, achieving a balance between indication flexibility and signaling overhead.

[0242] Step 530: The first communication device monitors, receives, or sends at least one information group based on the first indication information.

[0243] Based on the first indication information, the first communications device monitors at least one control information group; and / or sends or receives at least one data information group; and / or sends or receives at least one mixed information group. Optionally, the above-mentioned information groups may be transmitted periodically or aperiodically. In the case of periodic transmission, the first indication information may also carry a periodic parameter for the information group.

[0244] In summary, the method provided in this embodiment involves a first terminal device first reporting transmission characteristic information of an information group. Based on the transmission characteristic information of the information group, a second terminal device can generate first indication information for the information group. In subsequent transmissions, the first terminal device can use the first indication information to implement monitoring or transmission based on the information group as a scheduling unit, thereby reducing control signaling overhead and improving the transmission efficiency of the communication system.
