[0036] In conjunction with some embodiments of the first aspect, at least one of the primitive polynomial, the cyclic shift value, and the generator polynomial scrambling code of the first sequence, along with the first time-frequency resource, is used to indicate the activation of the first SPS scheduling. This allows for accurate indication of the activation of the first SPS scheduling.

[0037] In conjunction with some embodiments of the first aspect, the first SPS scheduling is sent by a network device to at least one terminal device, wherein the at least one terminal device includes the first terminal device.

[0038] In conjunction with some embodiments of the first aspect, the first time-frequency resource is determined based on the time-frequency resource occupied by the Physical Downlink Shared Channel (PDSCH) scheduled by the first SPS.

[0044] The first time-frequency resource includes the same frequency domain resources as the central frequency domain resources occupied by the PDSCH.

[0122] In some embodiments, the commonly used scheduling method in New Radio (NR) is dynamic scheduling, which involves scheduling a Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH) using a Downlink Control Information (DCI). Taking DCI-driven dynamic scheduling of PDSCH as an example, as shown in Figure 1B, the base station (gNB) first sends a DCI (DCI#1), and then sends PDSCH#1 at a specific location based on the scheduling information carried in the DCI. DCI#1 carries indication information such as time-frequency resources for PDSCH#1. Correspondingly, the terminal device blindly detects DCI#1 on the Physical Downlink Control Channel (PDCCH) channel, and then receives the corresponding PDSCH based on the time-frequency resource indication information of this DCI. Then, it blindly detects the next DCI and receives the corresponding PDSCH based on the time-frequency resource indication information of that DCI. Similarly, before sending the PDSCH, the base station will first send a DCI to dynamically indicate the PDSCH's time and frequency resources and other transmission parameters. Correspondingly, the terminal device will first use a blind detection DCI to dynamically obtain the PDSCH's transmission parameters, and then receive the PDSCH based on the PDSCH transmission parameters carried in the DCI.

[0123] In some embodiments, unlike dynamic scheduling, semi-persistent scheduling (SPS) for PDSCH can reduce the number of blind DCI detections by the terminal device, further reducing latency and power consumption. For example, a DCI or RRC reconfiguration message can indicate several (persistent) PDSCHs or PUSCHs. Once the terminal device receives a specific DCI or RRC reconfiguration message, it begins periodically receiving PDSCHs or sending PUSCHs until this persistent scheduling stops. During this persistent scheduling period, the terminal device does not need to perform DCI detections again; this is semi-persistent scheduling. Compared to dynamic scheduling, semi-persistent scheduling (SPS) reduces the number of blind DCI detections required by the terminal device, lowering transmission latency and power consumption.

[0124] In some embodiments, the SPS PDSCH scheduling process can be divided into two parts: first, pre-configuring necessary parameters such as the SPS PDSCH transmission period through Radio Resource Control (RRC); and second, activating or releasing SPS PDSCH transmission through DCI. Before configuring SPS parameters in RRC signaling, the base station also assigns a Configured Scheduling (CS) – Radio Network Temporary Identifier (RNTI) – to each terminal device to identify different terminal devices. Combining the two parts of the SPS PDSCH scheduling process, as shown in Figure 1C, the base station sending SPS PDSCH or the terminal device receiving SPS PDSCH involves two steps:

[0125] Step 1: The base station sends the necessary parameters for the SPS PDSCH via RRC configuration or reconfiguration signaling, including the period, the number of Hybrid Automatic Repeat Request (HARQ) processes, and the Modulation and Coding Scheme (MCS) table. Correspondingly, the terminal equipment receives the necessary parameter configuration for the SPS PDSCH.

[0126] Step 2: The base station sends CS-RNTI scrambled DCIs (including DCI#1 or DCI#2) to activate or release SPS transmission. DCI#1 is used to activate SPS PDSCH transmission; that is, after DCI#1 is sent, PDSCH#1 can be sent at the first candidate resource location of the SPS PDSCH. DCI#1 also contains frequency domain resource configuration information, including Frequency Domain Resource Allocation (FDRA) indication information and MCS indication information. DCI#2 is used to release SPS PDSCH transmission; that is, before DCI#2 is sent, the base station sends PDSCH#1 and PDSCH#2 sequentially according to the period configured in the RRC. After DCI#2 is sent, the time-frequency resource location where PDSCH#3 is located is no longer used to send PDSCH#3. Correspondingly, the terminal device receives the period and other configuration information in the RRC, listens to the corresponding CS-RNTI scrambled DCI, and then determines the start and end positions for receiving SPS PDSCH based on the DCI.

[0127] Based on the SPS PDSCH transmission mechanism described above, the PDCCH allocated to SPS for scheduling activation or release must simultaneously satisfy the following:

[0128] 1) The Cyclic Redundancy Check (CRC) associated with the DCI format is scrambled by CS-RNTI or G-CS-RNTI. In the embodiments of this disclosure, CS-RNTI is used uniformly without distinguishing between CS-RNTI and G-CS-RNTI.

[0129] 2) The NDI field in the DCI format is set to "0".

[0130] 3) If a DFI field exists in the DCI format, this field is set to "0".

[0131] 4) The TDRA field in the DCI format is indicated by a single SLIV.

[0132] 5) When scheduling is active and a PDSCH-to-HARQ_feedback timing indication exists, the PDSCH-to-HARQ_feedback timing indication field does not provide an inapplicable value.

[0133] When DCI indicates SPS scheduling activation, in addition to indicating activation, it is also necessary to indicate FDRA and MCS parameters; when DCI indicates SPS scheduling release, only a release message is needed.

[0134] In some embodiments, the terminal device obtains SPS scheduling activation indication information based on DCI blind detection. From the perspective of the terminal device, the DCI-based SPS scheduling activation indication method requires relatively high power consumption. In some examples, power consumption simulation tests show that the relative power consumption required for PDCCH blind detection is higher than that for sequence detection.

[0135] To this end, this disclosure proposes a communication scheme that transmits activation information via time-frequency resources and a specific first sequence instruction SPS, and carries SPS scheduling activation information via the first sequence, thereby saving the detection power consumption of the terminal and reducing the DCI resource overhead on the network side.

[0136] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the method includes the following steps:

[0137] Step S2101: The network device sends the first sequence to the terminal device group on the first time-frequency resource.

[0138] In some embodiments, the terminal device group may include at least one terminal device.

[0139] In some embodiments, the first time-frequency resource and the first sequence can be used to indicate SPS scheduling activation, such as indicating first SPS scheduling activation, where the first SPS scheduling is sent by the network device to a group of terminal devices, or where the first SPS scheduling is sent by the network device to at least one terminal device, the group of terminal devices may include the first terminal device, the first terminal device performs first SPS scheduling activation according to the first time-frequency resource and the first sequence, and the first terminal device may periodically receive PDSCH or send PUSCH according to the first SPS scheduling.

[0140] In some embodiments, the first sequence may carry SPS scheduling activation information.

[0141] In some embodiments, the first sequence may be a newly added sequence, and the terminal device may blindly detect the newly added sequence to obtain SPS scheduling activation information, which is much lower in power consumption than the terminal device performing PDCCH blind detection.

[0142] In some embodiments, at least one of the primitive polynomial, cyclic shift value, and generator polynomial scrambling code of the first sequence, and the first time-frequency resource, can be used to indicate a first SPS scheduling activation, which is sent by the network device to the terminal device group. For example, the SPS scheduling activation information is carried by at least one of the primitive polynomial, cyclic shift value, and generator polynomial scrambling code of the first sequence. For example, the terminal device group may include a first terminal device, which performs the first SPS scheduling activation according to at least one of the primitive polynomial, cyclic shift value, and generator polynomial scrambling code of the first sequence and the first time-frequency resource.

[0143] In some embodiments, the sequence type of the first sequence may be an m-sequence, a Gold sequence, or a ZC sequence, etc.

[0144] In some embodiments, the sequence length of the first sequence can be 8, 16, 32, or 64, etc.

[0145] In some embodiments, when a network device needs to instruct each terminal device in a terminal device group to activate a first SPS schedule, it may send a first sequence to the terminal device group on a first time-frequency resource.

[0146] In some embodiments, a network device may send a first sequence to a group of terminal devices on a first time-frequency resource. The first sequence occupies at least one time unit in the time domain and may occupy consecutive resource elements (REs) in the frequency domain, thus forming the first time-frequency resource. In some examples, the time unit may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a sub-slot, a mini-slot, a slot, a subframe, or a microsecond, etc., which may be an integer time unit or a non-integer number of time units, such as an integer microsecond or a non-integer microsecond.

[0147] For example, the first sequence occupies at least one OFDM symbol (OS) in the time domain and may occupy consecutive REs in the frequency domain, forming the first time-frequency resource. The first sequence transmitted on the first time-frequency resource can be used to indicate the SPS PDSCH scheduling activation information of a terminal equipment group. If the SPS PDSCH belongs to the first SPS scheduling, the first sequence indicates the activation of the first SPS scheduling.

[0148] In some embodiments, each terminal device in the terminal device group can receive a first sequence sent by the network device on the first time-frequency resource. Taking the first terminal device in the terminal device group as an example, when the first terminal device determines the first time-frequency resource and detects the first sequence on the first time-frequency resource, it can obtain the activation information of the first SPS scheduling based on the first sequence. For example, if it obtains the SPS PDSCH scheduling activation information, it can then start periodically receiving PDSCH; or if it obtains the SPS PUSCH scheduling activation information, it can then start periodically sending PUSCH.

[0149] In some embodiments, the first time-frequency resource may be predefined by the protocol.

[0150] In some embodiments, the first time-frequency resource can be determined based on the time-frequency resource occupied by the PDSCH scheduled by the first SPS, or it can be determined based on the time-frequency resource occupied by the PUSCH scheduled by the first SPS. The following explanation mainly uses PDSCH as an example:

[0151] In some examples, the time-domain resources contained in the first time-frequency resource can be determined by the offset between the first time unit occupied by the first PDSCH of the first SPS scheduling, as shown in Figure 2B. This offset can be determined based on the offset between the time-domain resources contained in the first time-frequency resource and the first OFDM symbol (OS) occupied by the PDSCH. For example, the time-domain offset can be N OFDM symbols, where N>=1.

[0152] In some examples, the time-domain resources contained in the first time-frequency resource can be determined by the offset between the first PDSCH scheduled by the first SPS and the last time unit occupied by the PDSCH, as shown in Figure 2C. This offset can be determined based on the offset between the time-domain resources contained in the first time-frequency resource and the last OFDM symbol (OS) occupied by the PDSCH. For example, the time-domain offset can be N OFDM symbols, where N>=1.

[0153] In some examples, the frequency domain resources contained in the first time-frequency resource may be the same as the central frequency domain resources occupied by the PDSCH scheduled by the first SPS. For example, the frequency domain location of the first time-frequency resource may be the same as or a part of the frequency domain resources occupied by the SPS PDSCH.

[0154] In some embodiments, the first time-frequency resource can also be configuration-based. For example, before the network device sends the first sequence according to the first time-frequency resource, the configuration information of the first time-frequency resource can be pre-configured via RRC, wherein the configuration information of the first time-frequency resource includes time-domain location information and frequency-domain location information.

[0155] In some embodiments, if the first sequence is transmitted on a second time-frequency resource to indicate the activation of a second SPS scheduling, such as when a network device transmits the first sequence to a second terminal device on the second time-frequency resource, the second time-frequency resource and the first sequence are used to indicate the activation of the second SPS scheduling. The second SPS scheduling may be transmitted by the network device to another group of terminal devices, which includes the second terminal device, and the second time-frequency resource is different from the first time-frequency resource. Similarly, if the same sequence is transmitted on different time-frequency resources, it may indicate the activation of SPS scheduling for different groups of terminal devices.

[0156] In some embodiments, a second sequence transmitted by a network device on a first time-frequency resource can be used to indicate the activation of a second SPS scheduling, such as transmitting the second sequence to a second terminal device on the first time-frequency resource. The first time-frequency resource and the second sequence are used to indicate the activation of the second SPS scheduling. The second SPS scheduling can be transmitted by the network device to another group of terminal devices, which includes the second terminal device. The second sequence is different from the first sequence. The different sequences can be associated with multiple primitive polynomials, and / or multiple cyclic shift values, and / or multiple generator polynomial scrambling codes. It can be understood that when the primitive polynomials of two sequences are different, the two sequences are different sequences; when the cyclic shift values ​​of two sequences are different, the two sequences are also different sequences; when the generator polynomial scrambling codes of two sequences are different, the two sequences are also different sequences. For example, different sequences transmitted on the same time-frequency resource can indicate the activation of SPS scheduling for different groups of terminal devices.

[0157] In some embodiments, a second sequence transmitted by a network device on a second time-frequency resource can be used to indicate the activation of a second SPS scheduling, such as transmitting a second sequence to a second terminal device on the second time-frequency resource. The second time-frequency resource and the second sequence are used to indicate the activation of the second SPS scheduling. The second SPS scheduling can be transmitted by the network device to another group of terminal devices, where the second time-frequency resource is different from the first time-frequency resource, and the other group of terminal devices includes the second terminal device. The second sequence is different from the first sequence. The different sequences can be associated with multiple primitive polynomials, and / or multiple cyclic shift values, and / or multiple generator polynomial scrambling codes. It can be understood that when the primitive polynomials of two sequences are different, the two sequences are different sequences; when the cyclic shift values ​​of two sequences are different, the two sequences are also different sequences; when the generator polynomial scrambling codes of two sequences are different, the two sequences are also different sequences. For example, different sequences transmitted on different time-frequency resources can indicate the activation of SPS scheduling for different groups of terminal devices.

[0158] In some examples, the time-domain resources included in the second time-frequency resource may be the same as those included in the first time-frequency resource, and the frequency-domain resources included in the second time-frequency resource may be different from those included in the first time-frequency resource; or, the time-domain resources included in the second time-frequency resource may be different from those included in the first time-frequency resource, and the frequency-domain resources included in the second time-frequency resource may be the same as those included in the first time-frequency resource; or, the time-domain resources included in the second time-frequency resource may be different from those included in the first time-frequency resource, and the frequency-domain resources included in the second time-frequency resource may be different from those included in the first time-frequency resource.

[0159] In some examples, the second time-frequency resource is determined based on the time-frequency resource occupied by the PDSCH scheduled by the second SPS. For details, please refer to the method for determining the first time-frequency resource, which will not be repeated here.

[0160] In addition to indicating SPS scheduling activation, network devices also need to indicate Frequency Domain Resource Allocation (FDRA) information and Modulation and Coding Technology (MCS) information. For this purpose, in some embodiments, the network device sends first information to the terminal device group; wherein, the first information can be used to indicate FDRA information and / or MCS information.

[0161] In some examples, the initial information can be carried by at least one of the following:

[0162] Third sequence; RRC message.

[0163] For example, SPS scheduling activation can be indicated via a first sequence. In addition, FDRA information and / or MCS information can be indicated via a third sequence, different from the first sequence. This information can be carried directly by the third sequence, or it can carry index information of pre-configured FDRA and / or MCS information. For example, several types of FDRA and MCS information, or combinations of FDRA and MCS information, can be pre-configured, and the corresponding index information can be indicated via the third sequence to inform the terminal device of the FDRA and MCS information.

[0164] For example, SPS scheduling can be activated by indicating the first sequence. In addition, FDRA information and / or MCS information can be configured through RRC messages. The RRC message can be an RRC message with pre-configured SPS parameters (such as the sending period of SPS PDSCH). In this way, extra RRC messages are avoided, saving resource consumption.

[0165] In some embodiments, the network device may also indicate FDRA information and / or MCS information via a first sequence. That is, in addition to indicating SPS scheduling activation, the first sequence also indicates FDRA information and / or MCS information. FDRA information and / or MCS information can be directly carried by the first sequence, or pre-configured index information of FDRA information and / or MCS information can be carried by the first sequence. For example, several types of FDRA information and MCS information, or combinations of FDRA information and MCS information, can be pre-configured, and the corresponding index information can be indicated by the first sequence to inform the terminal device of the FDRA information and MCS information.

[0166] As shown in Figure 2D, the scrambled CS-RNTI and verification field corresponding to the CRC of the DCI can indicate the SPS PDSCH scheduling activation of a specific terminal device. From the perspective of the terminal device, this method of SPS scheduling activation indication based on DCI requires high power consumption. As shown in Figure 2E, this disclosure proposes a method for indicating SPS transmission activation information through sequence indication. The terminal device does not need to blindly detect the DCI to obtain SPS scheduling activation information, and the power consumption of the terminal device can be saved by using sequence detection. Furthermore, the base station does not need to send the DCI carrying the SPS scheduling activation information; by carrying the SPS scheduling activation information through the first sequence, network overhead can be saved.

[0167] This disclosure proposes a communication scheme that instructs a group of terminal devices to transmit SPS activation information via a first sequence on a first time-frequency resource. For example, the SPS scheduling activation information is carried by at least one of the primitive polynomial, cyclic shift value, and generator polynomial scrambling code of the first sequence, so as to save the detection power consumption of the terminal devices and reduce the DCI resource overhead on the network side.

[0168] Figure 2F is an interactive schematic diagram of another communication method according to an embodiment of the present disclosure. As shown in Figure 2F, the method includes the following steps:

[0169] Step S2201: The network device sends a first sequence to the terminal device on the first time-frequency resource.

[0170] In some embodiments, the first time-frequency resource and the first sequence can be used to indicate SPS scheduling activation, such as indicating first SPS scheduling activation, which is sent by the network device to the terminal device, or the first SPS scheduling is sent by the network device to the first terminal device. Unlike Figure 2A, where the network device indicates SPS scheduling activation to a group of terminal devices, in Figure 2F, the network device can indicate SPS scheduling activation to a single terminal device. For ease of description, the following explanation uses a single terminal device as the first terminal device as an example. The first terminal device performs first SPS scheduling activation based on the first time-frequency resource and the first sequence.

[0171] In some embodiments, the first sequence may carry SPS scheduling activation information.

[0172] In some embodiments, the first sequence may be a newly added sequence, and the first terminal device may blindly detect the newly added sequence to obtain SPS scheduling activation information, which is much lower in power consumption than the first terminal device performing PDCCH blind detection.

[0173] In some embodiments, at least one of the primitive polynomial, cyclic shift value, and generator polynomial scrambling code of the first sequence, and the first time-frequency resource, can be used to indicate the activation of the first SPS scheduling, which is sent by the network device to the first terminal device, such as by carrying SPS scheduling activation information through at least one of the primitive polynomial, cyclic shift value, and generator polynomial scrambling code of the first sequence, such as the first terminal device performing the first SPS scheduling activation according to at least one of the primitive polynomial, cyclic shift value, and generator polynomial scrambling code of the first sequence and the first time-frequency resource.

[0174] In some embodiments, the sequence type of the first sequence may be an m-sequence, a Gold sequence, or a ZC sequence, etc.

[0175] In some embodiments, the sequence length of the first sequence can be 8, 16, 32, or 64, etc.

[0176] In some embodiments, when a network device needs to instruct a first terminal device to activate a first SPS scheduling, it may send a first sequence to the first terminal device on a first time-frequency resource.

[0177] In some embodiments, a network device may send a first sequence to a first terminal device on a first time-frequency resource. The first sequence occupies at least one time unit in the time domain and may occupy consecutive resource elements (REs) in the frequency domain, thus forming the first time-frequency resource. In some examples, the time unit may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a sub-slot, a mini-slot, a slot, a subframe, or a microsecond, etc., which may be an integer time unit or a non-integer number of time units, such as an integer microsecond or a non-integer microsecond.

[0178] For example, the first sequence occupies at least one OFDM symbol (OS) in the time domain and may occupy consecutive REs in the frequency domain, forming the first time-frequency resource. The first sequence transmitted on the first time-frequency resource can be used to indicate the SPS PDSCH scheduling activation information of the first terminal device. If the SPS PDSCH belongs to the first SPS scheduling, the first sequence indicates the activation of the first SPS scheduling.

[0179] In some embodiments, the first terminal device may receive a first sequence sent by the network device on the first time-frequency resource. When the first terminal device determines the first time-frequency resource and detects the first sequence on the first time-frequency resource, it may obtain the activation information of the first SPS scheduling based on the first sequence. For example, if it obtains the SPS PDSCH scheduling activation information, it may start to periodically receive PDSCH; or if it obtains the SPS PUSCH scheduling activation information, it may start to periodically send PUSCH.

[0180] In some embodiments, the first time-frequency resource may be predefined by the protocol.

[0181] In some embodiments, the first time-frequency resource can be determined based on the time-frequency resource occupied by the PDSCH scheduled by the first SPS, or it can be determined based on the time-frequency resource occupied by the PUSCH scheduled by the first SPS. The following explanation mainly uses PDSCH as an example:

[0182] In some examples, the time-domain resources contained in the first time-frequency resource can be determined by the offset between the first time unit occupied by the first PDSCH of the first SPS scheduling, as shown in Figure 2B. This offset can be determined based on the offset between the time-domain resources contained in the first time-frequency resource and the first OFDM symbol (OS) occupied by the PDSCH. For example, the time-domain offset can be N OFDM symbols, where N>=1.

[0183] In some examples, the time-domain resources contained in the first time-frequency resource can be determined by the offset between the first PDSCH scheduled by the first SPS and the last time unit occupied by the PDSCH, as shown in Figure 2C. This offset can be determined based on the offset between the time-domain resources contained in the first time-frequency resource and the last OFDM symbol (OS) occupied by the PDSCH. For example, the time-domain offset can be N OFDM symbols, where N>=1.

[0184] In some examples, the frequency domain resources contained in the first time-frequency resource may be the same as the central frequency domain resources occupied by the PDSCH scheduled by the first SPS. For example, the frequency domain location of the first time-frequency resource may be the same as or a part of the frequency domain resources occupied by the SPS PDSCH.

[0185] In some embodiments, the first time-frequency resource can also be configuration-based. For example, before the network device sends the first sequence according to the first time-frequency resource, the configuration information of the first time-frequency resource can be pre-configured via RRC. The configuration information of the first time-frequency resource includes time-domain location information and frequency-domain location information.

[0186] In some embodiments, if the first sequence is transmitted on a second time-frequency resource to indicate the activation of a second SPS scheduling, such as when a network device transmits the first sequence to a second terminal device on the second time-frequency resource, the second time-frequency resource and the first sequence are used to indicate the activation of the second SPS scheduling. The second SPS scheduling may be transmitted by the network device to another terminal device, such as a second terminal device different from the first terminal device, and the second time-frequency resource is different from the first time-frequency resource. Similarly, if the same sequence is transmitted on different time-frequency resources, it may indicate the activation of SPS scheduling for different terminal devices.

[0187] In some embodiments, a second sequence transmitted by a network device on a first time-frequency resource can be used to indicate the activation of a second SPS scheduling, such as transmitting the second sequence to a second terminal device on the first time-frequency resource. The first time-frequency resource and the second sequence are used to indicate the activation of the second SPS scheduling. The second SPS scheduling can be transmitted by the network device to another terminal device, such as a second terminal device different from the first terminal device. The second sequence is different from the first sequence. The different sequences can be associated with multiple primitive polynomials, and / or multiple cyclic shift values, and / or multiple generator polynomial scrambling codes. It can be understood that when the primitive polynomials of two sequences are different, the two sequences are different sequences; when the cyclic shift values ​​of two sequences are different, the two sequences are also different sequences; when the generator polynomial scrambling codes of two sequences are different, the two sequences are also different sequences. For example, different sequences transmitted on the same time-frequency resource can indicate the activation of SPS scheduling for different terminal devices.

[0188] In some embodiments, a second sequence transmitted by a network device on a second time-frequency resource can be used to indicate the activation of a second SPS scheduling, such as transmitting the second sequence to a second terminal device on the second time-frequency resource. The second time-frequency resource and the second sequence are used to indicate the activation of the second SPS scheduling. The second SPS scheduling can be transmitted by the network device to another terminal device, such as a second terminal device different from the first terminal device. The second time-frequency resource is different from the first time-frequency resource, and the second sequence is different from the first sequence. The different sequences can be associated with multiple primitive polynomials, and / or multiple cyclic shift values, and / or multiple generator polynomial scrambling codes. It can be understood that when the primitive polynomials of two sequences are different, the two sequences are different sequences; when the cyclic shift values ​​of two sequences are different, the two sequences are also different sequences; when the generator polynomial scrambling codes of two sequences are different, the two sequences are also different sequences. For example, different sequences transmitted on different time-frequency resources can indicate the activation of SPS scheduling for different terminal devices.

[0189] In some examples, the time-domain resources included in the second time-frequency resource may be the same as those included in the first time-frequency resource, and the frequency-domain resources included in the second time-frequency resource may be different from those included in the first time-frequency resource; or, the time-domain resources included in the second time-frequency resource may be different from those included in the first time-frequency resource, and the frequency-domain resources included in the second time-frequency resource may be the same as those included in the first time-frequency resource; or, the time-domain resources included in the second time-frequency resource may be different from those included in the first time-frequency resource, and the frequency-domain resources included in the second time-frequency resource may be different from those included in the first time-frequency resource.

[0190] In some examples, the second time-frequency resource is determined based on the time-frequency resource occupied by the PDSCH scheduled by the second SPS. For details, please refer to the method for determining the first time-frequency resource, which will not be repeated here.

[0191] For example, to instruct different terminal devices to activate their SPS scheduling separately, the terminal device identification information can be carried through different time-frequency resources or different sequences. When the terminal device identification information is carried through different time-frequency resources, multiple sets of time-frequency resources can be defined to send at least one new sequence. These multiple sets of time-frequency resources include a first time-frequency resource and a second time-frequency resource. The first time-frequency resource is used to indicate the SPS PDSCH scheduling activation information of the first terminal device, and the second time-frequency resource is used to indicate the SPS PDSCH scheduling activation information of the second terminal device. As shown in Figures 2G to 2I, carrying the SPS PDSCH scheduling activation information of multiple terminal devices on multiple sets of time-frequency resources can be divided into three possible specific carrying methods, as shown in Figures 2G, 2H, and 2I. As shown in Figure 2G, the two sets of time-frequency resources contain the same frequency domain resources but different time domain resources. As shown in Figure 2H, the two sets of time-frequency resources contain the same time domain resources but different frequency domain resources, and the frequency domain resources contained in the two sets of time-frequency resources do not overlap and appear alternately. As shown in Figure 2I, the two sets of time-frequency resources contain different time-domain and frequency-domain resources. For example, the frequency-domain resources contained in the two sets of time-frequency resources do not overlap and appear alternately, and the alternating patterns are different on different symbols.

[0192] When terminal device identification information is carried through different sequences, SPS PDSCH scheduling activation information for at least one terminal device can be indicated by sending different newly added sequences on the same time-frequency resources. These different sequences can be associated with multiple primitive polynomials, and / or multiple cyclic shift values, and / or multiple generator polynomial scrambling codes. This can be understood as follows: when the primitive polynomials of two sequences are different, the two sequences are considered different sequences. Similarly, when the cyclic shift values ​​of two sequences are different, the two sequences are also considered different sequences. Regarding sequence type and sequence length, for example, the sequence type can be an m-sequence, a Gold sequence, or a ZC sequence, and the sequence length can be 8, 16, 32, or 64, etc. Furthermore, the method of carrying indication information through different sequences can be combined with the method of carrying indication information through different time-frequency resources. For example, two different sequences can be sent on two different sets of time-frequency resources to indicate SPS scheduling activation information for two terminal devices.

[0193] In addition to indicating SPS scheduling activation, the network device also needs to indicate Frequency Domain Resource Allocation (FDRA) information and Modulation and Coding Technology (MCS) information. For this purpose, in some embodiments, the network device sends first information to the first terminal device; wherein, the first information can be used to indicate FDRA information and / or MCS information.

[0194] In some examples, the initial information can be carried by at least one of the following:

[0195] Third sequence; RRC message.

[0196] For example, SPS scheduling activation can be indicated via a first sequence. In addition, FDRA information and / or MCS information can be indicated via a third sequence, different from the first sequence. This information can be carried directly by the third sequence, or it can carry index information of pre-configured FDRA and / or MCS information. For example, several types of FDRA and MCS information, or combinations of FDRA and MCS information, can be pre-configured, and the corresponding index information can be indicated via the third sequence to inform the terminal device of the FDRA and MCS information.

[0197] For example, SPS scheduling can be activated by indicating the first sequence. In addition, FDRA information and / or MCS information can be configured through RRC messages. The RRC message can be an RRC message with pre-configured SPS parameters (such as the sending period of SPS PDSCH). In this way, extra RRC messages are avoided, saving resource consumption.

[0198] In some embodiments, the network device may also indicate FDRA information and / or MCS information via a first sequence. That is, in addition to indicating SPS scheduling activation, the first sequence also indicates FDRA information and / or MCS information. FDRA information and / or MCS information can be directly carried by the first sequence, or pre-configured index information of FDRA information and / or MCS information can be carried by the first sequence. For example, several types of FDRA information and MCS information, or combinations of FDRA information and MCS information, can be pre-configured, and the corresponding index information can be indicated by the first sequence to inform the terminal device of the FDRA information and MCS information.

[0199] This disclosure proposes a communication scheme that transmits activation information via a first sequence on a first time-frequency resource, such as carrying user identification information and / or SPS scheduling activation information via at least one of the primitive polynomial, cyclic shift value, generator polynomial scrambling code, and occupied time-frequency resource of the first sequence, so as to save detection power consumption of terminal equipment and reduce DCI resource overhead on the network side.

[0200] Figure 3 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the method includes:

[0201] Step S301: The network device sends a first sequence to the first terminal device on the first time-frequency resource.

[0202] In some embodiments, the first time-frequency resource and the first sequence are used for the first SPS scheduling activation.

[0203] Optionally, the alternative implementations of step S301 can be found in the alternative implementations shown in Figures 2A to 2I, which will not be repeated here.

[0204] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0205] This disclosure proposes a communication scheme that transmits activation information via a first sequence instruction SPS on a first time-frequency resource. This scheme can carry user identification information and / or SPS scheduling activation information by adding at least one of the primitive polynomial, cyclic shift value, generator polynomial scrambling code, or occupied time-frequency resource of the sequence. This saves the detection power consumption of the terminal and reduces the DCI resource overhead on the network side.

[0206] The following are some exemplary specific solutions proposed in the embodiments of this disclosure:

[0207] This embodiment of the disclosure saves terminal detection power consumption by adding a sequence indicator SPS transmission activation information and / or UE identification information and / or frequency domain resource indicator information FDRA and / or modulation and coding information MCS, and by adding at least one of the primitive polynomial, cyclic shift value, generator polynomial scrambling code, and occupied time and frequency resources of the sequence to carry the SPS transmission activation information and / or frequency domain resource indicator information FDRA and / or modulation and coding information MCS.

[0208] Method Overview:

[0209] As shown in Figures 2D and 2E, this disclosure proposes a novel method for indicating SPS transmission activation information, and / or UE identification information, and / or Frequency Domain Resource Indication Information (FDRA), and / or Modulation and Coding Information (MCS), based on a newly added sequence. Compared to the related technologies shown in the circles in Figure 2D, which use the scrambled CS-RNTI and verification field corresponding to the CRC of the DCI to indicate the SPS PDSCH scheduling activation for a specific terminal device or terminal device group, and then use the FDRA and MCS fields in the DCI to indicate the frequency domain resources occupied by the SPS PDSCH and the modulation and coding parameters used, the key point of this disclosure lies in how to carry 1 bit of SPS PDSCH scheduling activation information, and / or terminal device identification information, and / or Frequency Domain Resource Indication Information (FDRA), and / or Modulation and Coding Information (MCS) through the parameters of the newly added sequence.

[0210] Regarding the key points of this disclosure embodiment—how to carry 1 bit of SPS PDSCH scheduling activation information, and / or, terminal device identification information, and / or, frequency domain resource indication information FDRA, and / or, modulation and coding information MCS by adding a sequence—there are four possible cases, which will be described in detail below.

[0211] The first possible scenario is to indicate SPS PDSCH scheduling activation information and / or, frequency domain resource indication information FDRA, and / or, modulation and coding information MCS by adding a new sequence per terminal device group.

[0212] The newly added sequence occupies at least one OFDM symbol in the time domain and consecutive resource elements (REs) in the frequency domain, forming the first time-frequency resource. The newly added sequence transmitted on the first time-frequency resource can be used to indicate SPS PDSCH scheduling activation information for a group of terminal devices. When a terminal device identifies the first time-frequency resource and detects a newly added sequence on it, it can obtain the SPS PDSCH scheduling activation information.

[0213] The first time-frequency resource can be predefined by the protocol. For example, the time-domain location can be determined by the offset between it and the first or last symbol of the SPS PDSCH, and the frequency-domain location can be the same as or a part of the frequency-domain resources occupied by the SPS PDSCH. For example, the time-domain offset can be N OFDM symbols, where N>=1.

[0214] The first time-frequency resource can also be configuration-based. Before the base station sends a new sequence based on the first time-frequency resource, the configuration information of the first time-frequency resource can be pre-configured through RRC. The configuration information of the first time-frequency resource includes time-domain location information and frequency-domain location information.

[0215] When it is necessary to further carry frequency domain resource indication information and / or modulation and coding information through newly added sequences, different sequences can be used to carry it directly, or different sequences can be used to carry pre-configured frequency domain resource indication information and / or modulation and coding information index information. For example, several types of frequency domain resource indication information, modulation and coding information, or combinations of frequency domain resource indication information and modulation and coding information can be pre-configured.

[0216] The second possible scenario is to add a new sequence per terminal device to indicate SPS PDSCH scheduling activation information, and / or, frequency domain resource indication information FDRA, and / or, modulation and coding information MCS.

[0217] Terminal device identification information can be carried through different time and frequency resources, or through different sequences.

[0218] When terminal device identification information is carried through different time-frequency resources, multiple sets of time-frequency resources can be defined to send at least one new sequence. These multiple sets of time-frequency resources include a first time-frequency resource and a second time-frequency resource. The first time-frequency resource is used to indicate the SPS PDSCH scheduling activation information of the first terminal device, and the second time-frequency resource is used to indicate the SPS PDSCH scheduling activation information of the second terminal device.

[0219] As shown in Figures 2G to 2I, carrying SPS PDSCH scheduling activation information for multiple terminal devices on multiple sets of time-frequency resources can be divided into three possible specific carrying methods, as shown in Figures 2G, 2H, and 2I. As shown in Figure 2G, the two sets of time-frequency resources contain the same frequency domain resources but different time domain resources. As shown in Figure 2H, the two sets of time-frequency resources contain the same time domain resources but different frequency domain resources, and the frequency domain resources in the two sets of time-frequency resources do not overlap and alternate. As shown in Figure 2I, the two sets of time-frequency resources contain different time domain and frequency domain resources; for example, the frequency domain resources in the two sets of time-frequency resources do not overlap, alternate, and the alternating patterns are different on different symbols.

[0220] When terminal device identification information is carried through different sequences, the SPS PDSCH scheduling activation information of at least one terminal device can be indicated by sending different newly added sequences on the same time-frequency resources. These different sequences can be associated with multiple primitive polynomials, and / or multiple cyclic shift values, and / or multiple generator polynomial scrambling codes. It can be understood that when two sequences have different primitive polynomials, the two sequences are different sequences. When two sequences have different cyclic shift values, the two sequences are also different sequences. Regarding sequence type and sequence length, for example, the sequence type can be an m-sequence, a Gold sequence, or a ZC sequence, and the sequence length can be 8, 16, 32, or 64, etc.

[0221] When it is necessary to further carry frequency domain resource indication information and / or modulation and coding information through newly added sequences, different sequences can be used to carry it directly, or different sequences can be used to carry pre-configured frequency domain resource indication information and / or modulation and coding information index information. For example, several types of frequency domain resource indication information, modulation and coding information, or combinations of frequency domain resource indication information and modulation and coding information can be pre-configured.

[0222] As an alternative approach, the method of carrying indication information through different sequences can be combined with the method of carrying indication information through different time-frequency resources. For example, two different sequences can be sent on two sets of different time-frequency resources to indicate the SPS scheduling activation information of two terminal devices.

[0223] The third possible scenario is: SPS PDSCH scheduling activation information is indicated by adding a new sequence per terminal device group, frequency domain resource indication information FDRA is indicated by RRC message, and / or modulation and coding information MCS.

[0224] The specific implementation method is similar to the first case. When the frequency domain resource indication information FDRA and / or modulation and coding information MCS are indicated by the RRC message, the RRC message also includes at least one of the following: SPS period, MCS table, and HARQ process number.

[0225] The fourth possible scenario is: the SPS PDSCH scheduling activation information is indicated by adding a new sequence per terminal device, the frequency domain resource indication information FDRA is indicated by the RRC message, and / or the modulation and coding information MCS.

[0226] The specific implementation method is similar to the second case. When the Frequency Domain Resource Indication (FDRA) information and / or Modulation and Coding Information (MCS) are indicated by the RRC message, the RRC message also includes at least one of the following: SPS period, MCS table, and HARQ process number.

[0227] In some embodiments, the base station indicates SPS scheduling activation information for at least one terminal device by sending at least one first sequence. The first sequence may or may not include at least one of the primitive polynomial, cyclic shift value, generator polynomial scrambling code, and occupied time-frequency resources, which may be used to carry user identification information and / or SPS scheduling activation information. The first sequence may also be used to indicate terminal device identification information and / or Frequency Domain Resource Indication Information (FDRA) and / or Modulation and Coding Information (MCS); or, the FDRA and / or MCS may be carried through an RRC message containing information such as the SPS period and MCS table.

[0228] Accordingly, in some embodiments, the terminal device determines SPS scheduling activation information by receiving a first sequence. At least one of the primitive polynomial, cyclic shift value, generator polynomial scrambling code, and occupied time-frequency resources in the first sequence may or may not be used to carry user identification information and / or SPS scheduling activation information. The first sequence may also be used to indicate terminal device identification information and / or Frequency Domain Resource Indicator (FDRA) and / or Modulation and Coding Information (MCS); or, the FDRA and / or MCS may be carried through an RRC message containing information such as the SPS period and MCS table.

[0229] By applying the technical solution of this disclosure embodiment, the terminal device does not need to blindly detect DCI to obtain SPS scheduling activation information, and the power consumption of the terminal device can be saved by sequence detection. The network does not need to send DCI carrying SPS scheduling activation information, which can save network overhead.

[0230] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal device in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by the network device (e.g., access network device, core network functional node, core network device, etc.) in any of the above methods.

In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors.

The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD).

In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be hardware circuits designed for artificial intelligence, which can be understood as ASICs, such as Neural Network Processing Units (NPUs), Tensor Processing Units (TPUs), and Deep Learning Processing Units (DPUs).
