The wireless communication system 100 includes terminal devices with terminal devices, or terminal devices with network devices, or stations (STAs) with stations; this application does not limit the specific types of devices. Figure 1 uses the example of a wireless communication system 100 including network devices 110 and terminal devices 120. The number of network devices 110 can be one or more, and the number of terminal devices 120 can be one or more.

It can be a node or sensor of a vehicle (IoV), or a computing device with wireless communication capabilities or other processing devices connected to a wireless modem.

[0035] In some embodiments, both network device 110 and terminal device 120 support the 3rd Generation Partnership Project (3GPP) protocol, but are not limited to the 3GPP protocol.

[0036] In some embodiments, the frequency bands supported by the wireless communication system 100 include, but are not limited to: centimeter wave bands (such as bands in the range of 450MHz-6GHz, also called Sub-6GHz bands), millimeter wave (mmWave) bands (such as 45GHz, 60GHz, etc., which belong to the range of 30-300GHz), and low-frequency bands. Among them, low-frequency bands include Sub-7GHz bands (such as 2.4GHz, 5GHz, 6GHz, etc., which belong to the range of 1-7.25GHz).

[0037] The technical solutions described in some embodiments of this application can be applied to various communication systems, such as: 6th-Generation (6G) systems, subsequent evolution systems of 6G, NR systems, evolution systems of NR systems, 5th-Generation (5G) systems, Beyond 5th-Generation (B5G) systems, Long Term Evolution (LTE) systems, Advanced Long Term Evolution (LTE-A) systems, LTE-based access to unlicensed spectrum (LTE-U) systems, NR-based access to unlicensed spectrum (NR-U) systems, cellular IoT systems, Wireless Local Area Networks (WLAN) systems, Wireless Fidelity (Wi-Fi) systems, Global System for Mobile Communication (GSM) systems, Code Division Multiple Access (CDMA) systems, and Wideband Code Division Multiple Access (CDMA) systems. Systems such as WCDMA (Wide-accessible communication network), General Packet Radio Service (GPRS), Terrestrial Networks (TN), and Non-Terrestrial Networks (NTN) are included.

[0038] The wireless communication system 100 is applicable to three communication scenarios: the first is the uplink transmission scenario, which refers to the scenario where the terminal device sends signals to the network device; the second is the downlink transmission scenario, which refers to the scenario where the network device sends signals to the terminal device; and the third is the sidelink transmission scenario, which refers to the scenario where the terminal device sends signals to other terminal devices.

[0039] Taking data transmission as an example, wireless communication system 100 typically supports two downlink data transmission methods:

[0040] 1. Terminal device 120 receives higher-layer signaling, such as Radio Resource Control (RRC) signaling, sent by network device 110. Terminal device 120 then receives downlink data based on the parameters indicated by this higher-layer signaling. In LTE and NR systems, this scheduling method is called semi-persistent scheduling (SPS). For downlink data transmission with periodic arrivals, constant traffic volume, and stable transmission conditions (e.g., the UE does not move rapidly), using semi-persistent scheduling can reduce the scheduling signaling overhead in the communication system and simplify the receiving process at the receiving end.

[0041] 2. Terminal device 120 receives scheduling signaling from network device 110, such as Downlink Control Information (DCI). Terminal device 120 receives downlink data based on the parameters indicated by the DCI. This scheduling method is commonly referred to as dynamic scheduling. The advantage of dynamic scheduling is that the scheduler determines transmission parameters based on real-time traffic volume and physical channel conditions, resulting in high transmission efficiency. However, the UE needs to blindly detect the DCI, leading to higher complexity in DCI reception. Furthermore, the total processing delay for downlink data reception on the UE side includes both DCI demodulation and downlink data demodulation, resulting in a relatively large reception delay.

[0042] Similarly, if network device 110 dynamically schedules the UE to send uplink data, the UE also needs to receive DCI first, and then send uplink data based on the parameters indicated by DCI.

[0043] During dynamically scheduled data transmission, the power consumption of the UE performing blind detection on the downlink control channel is significant, which is detrimental to energy saving on the UE side. Therefore, this application proposes a communication method that helps reduce UE power consumption and improve system efficiency.

[0044] Figure 2 shows a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a UE and includes at least some of the following steps:

[0045] Step 220: Receive at least one first downlink channel; wherein, within a first time resource related to at least one first downlink channel, the first configuration information is not effective, the first configuration information is used to configure the parameters of at least one second downlink channel, and the at least one second downlink channel is used to carry scheduling signaling.

[0046] The UE receives at least one first downlink channel, that is, the UE receives downlink signals in at least one first downlink channel.

[0047] The first time resource is related to at least one first downlink channel. For example, the first time resource is determined based on at least one first downlink channel, or the time domain location of the first time resource is associated with the time domain location of at least one first downlink channel.

[0048] At least one second downlink channel carries scheduling signaling for scheduling downlink and / or uplink transmissions.

[0049] The first configuration information is ineffective, meaning that the parameters of at least one second downlink channel configured in the first configuration information are invalid. Therefore, when the first configuration information is ineffective, the UE cannot use the parameters configured in the first configuration information to receive and / or detect at least one second downlink channel. The first configuration information is agreed upon by the communication protocol, configured by the network device (e.g., via configuration signaling), or pre-configured. If the first configuration information is pre-configured, it may be implemented by pre-storing corresponding codes, tables, or other methods that can indicate relevant information in the UE, or by using a Configured Grant (CG). Alternatively, it may be implemented through Radio Resource Control (RRC) signaling sent by the network device.

[0050] In some embodiments, the first downlink channel includes a downlink data channel or a downlink shared channel.

[0051] In some embodiments, the second downlink channel includes a downlink control channel.

[0052] In this embodiment of the application, the UE can be the terminal device 120 shown in FIG1, and the network device can be the network device 110 shown in FIG1.

[0053] In summary, the method provided in this application embodiment ensures that the first configuration information of at least one second downlink channel is not effective within the first time resource related to at least one first downlink channel received by the UE. Therefore, the UE will not use the first configuration information to receive at least one second downlink channel within the first time resource, which can reduce or even abandon the UE's detection of the second downlink channel within the first time resource, and help to achieve energy saving on the UE side.

[0054] Specifically, for scenarios or UEs that do not support scheduling signaling updates, the UE processes multiple channels serially. Before the downlink data transmission scheduled by the network device is completed, the network device may not send subsequent scheduling signaling (at least for downlink data, and possibly also for uplink data). In other words, the processing of later-scheduled channels will not be earlier than that of earlier-scheduled channels. During the time the UE processes the earlier-scheduled channels, the UE can completely or partially abandon blind detection of the downlink control channels to save power.

[0055] In some embodiments, based on the embodiment shown in FIG2, step 220 can be further implemented as step 320, as shown in FIG3.

[0056] Figure 3 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a UE and includes at least some of the following steps:

[0057] Step 320: Receive downlink data and / or DCI in at least one first downlink channel; wherein, the first configuration information is not effective within a first time resource associated with at least one first downlink channel.

[0058] The UE receives at least one first downlink channel comprising downlink data and / or DCI. The DCI can also be implemented as scheduling signaling, used to schedule downlink and / or uplink data transmission. For example, at least one first downlink channel comprises downlink data, and / or, one of the at least one first downlink channels comprises a first DCI. Taking a Physical Downlink Shared Channel (PDSCH) as an example, at least one PDSCH comprises downlink data, and / or one of the at least one PDSCH comprises a first DCI, used to schedule subsequent downlink and / or uplink data transmission. Alternatively, at least one PDSCH comprises downlink data, and / or, one of the at least one PDSCH comprises a first scheduling signaling, used to schedule downlink and / or uplink data transmission. The transmission resources of the PDSCH scheduled by the DCI / scheduling signaling are determined. Multiplexing subsequent DCI / scheduling information within this PDSCH according to agreed-upon rules can significantly reduce the number of blind detections by the UE.

[0059] Whether a first downlink channel includes a first DCI can be determined in the following three ways:

[0060] (1) Indicate whether a first downlink channel includes a first DCI by a reference signal.

[0061] In some embodiments, at least one first downlink channel includes, in addition to the downlink data and / or DCI described above, a reference signal, which is used to indicate whether one of the first downlink channels includes a first DCI (or a first scheduling signaling).

[0062] For example, the UE identifies whether a first downlink channel carries a first DCI (or first scheduling signaling) by using a reference signal in a first downlink channel. Taking a PDSCH as an example, at least one PDSCH, PDSCH 1, includes a reference signal indicating whether PDSCH 1 includes the first DCI. If the reference signal indicates that PDSCH 1 includes the first DCI, then at least one PDSCH includes both the reference signal and the first DCI (and possibly downlink data). The UE can receive and / or detect the first DCI in PDSCH 1 based on the indication of the reference signal. The first DCI is used to schedule downlink data transmission and / or uplink data transmission after PDSCH 1. If the reference signal indicates that PDSCH 1 does not include the first DCI, the UE does not need to receive and / or detect the first DCI in PDSCH 1.

[0063] For example, the UE determines whether the next downlink channel carries the first DCI (or the first scheduling signaling) by using a reference signal in a first downlink channel. Taking the first downlink channel as a PDSCH as an example, at least one PDSCH, PDSCH 1, includes a reference signal indicating whether PDSCH 2 includes the first DCI. If the reference signal indicates that PDSCH 2 includes the first DCI, then at least one PDSCH includes the reference signal and the first DCI (and may also include downlink data). The UE can receive and / or detect the first DCI in PDSCH 2 according to the indication of the reference signal. The first DCI is used to schedule downlink data transmission and / or uplink data transmission after PDSCH 2. If the reference signal indicates that PDSCH 2 does not include the first DCI, the UE does not need to receive and / or detect the first DCI in PDSCH 2.

[0064] Furthermore, the reference signal may implicitly or explicitly indicate whether one of the first downlink channels includes the first DCI.

[0065] For example, the reference signal includes one or more indicator bits, and different values ​​of the indicator bits indicate whether one of the first downlink channels includes or excludes the first DCI.

[0066] For example, the cyclic shift information used by the reference signal indicates whether one of the at least one first downlink channels includes or excludes the first DCI. For instance, if the reference signal uses a first cyclic shift value, it indicates that one of the at least one first downlink channels includes the first DCI; if the reference signal uses a second cyclic shift value, it indicates that one of the at least one first downlink channels does not include the first DCI. The mapping relationship between the cyclic shift information and whether the first DCI is included is agreed upon by the communication protocol, configured by the network device (e.g., through configuration signaling), or pre-configured (e.g., through predefined codes, predefined tables, CG, or RRC signaling).

[0067] For example, the orthogonal covering codes (OCC) sequence used by the reference signal indicates whether one of the first downlink channels in at least one first downlink channel includes or excludes the first DCI. For instance, if the reference signal uses a first OCC sequence, it indicates that one of the first downlink channels in at least one first downlink channel includes the first DCI; if the reference signal uses a second OCC sequence, it indicates that one of the first downlink channels in at least one first downlink channel does not include the first DCI. The mapping relationship between the OCC sequence and whether the first DCI is included is agreed upon by the communication protocol, configured by the network device (e.g., through configuration signaling), or pre-configured (e.g., through predefined codes, predefined tables, CG, or RRC signaling).

[0068] Figure 4 illustrates a transmission diagram of a downlink channel provided in an exemplary embodiment of this application. Taking the first downlink channel as a PDSCH as an example, assuming that n PDSCHs (n≥1) include at least PDSCH 1 and PDSCH 2, PDSCH 2 includes a reference signal RS1. The reference signal RS1 is used to indicate whether PDSCH 2 includes or excludes DCI 1. DCI 1 is used to schedule subsequent downlink data transmission and / or uplink data transmission. Figure 4 uses RS1 indicating that PDSCH 2 includes DCI 1 as an example. Therefore, PDSCH 2 includes RS1 and DCI 1.

[0069] (2) Determine whether a first downlink channel includes a first DCI based on the detection results of the first resource.

[0070] In some embodiments, the detection result of a first resource in one of the first downlink channels is used to indicate whether the first downlink channel includes a first DCI (or a first scheduling signaling). The first resource is defined by a communication protocol, configured by a network device (e.g., through configuration signaling), or pre-configured (e.g., through predefined codes, CG, or RRC signaling). Therefore, the UE can determine whether the first downlink channel carries a first DCI based on the detection result of the first resource in a first downlink channel.

[0071] Taking the first downlink channel as PDSCH as an example, at least one PDSCH includes downlink data. The UE detects the first resource in PDSCH 1 of at least one PDSCH and determines whether it includes the first DCI based on the CRC detection result in the first resource. If the Cyclic Redundancy Check (CRC) in the first resource of PDSCH 1 passes, then PDSCH 1 carries the first DCI, and the UE needs to receive and / or detect the first DCI in PDSCH 1. The first DCI is used to schedule downlink data transmission and / or uplink data transmission after PDSCH 1. If the CRC in the first resource of PDSCH 1 fails, then PDSCH 1 does not carry the first DCI, and the UE does not need to receive and detect the first DCI in PDSCH 1.

[0072] (3) The first DCI is transmitted only within the second resource.

[0073] In some embodiments, the first DCI (or first scheduling signaling) is transmitted within a second resource in one of the at least one first downlink channels. The second resource is defined by the communication protocol, configured by the network device (e.g., via configuration signaling), or pre-configured (e.g., via predefined codes, CG, or RRC signaling). Therefore, the first DCI is transmitted only within a fixed resource. The UE can identify whether a first downlink channel includes the first DCI by detecting it only within the fixed resource of that first downlink channel. By limiting the resources used by the first DCI, the power consumption required for DCI detection is effectively reduced.

[0074] Taking PDSCH as an example, the UE detects the second resource of PDSCH 1 in at least one PDSCH. If the UE detects the first DCI in the second resource of PDSCH 1, the first DCI is used to schedule downlink data transmission and / or uplink data transmission after PDSCH 1. Then, the UE receives data based on the downlink data transmission scheduled by the first DCI or sends data based on the uplink data transmission scheduled by the first DCI. If the UE does not detect the first DCI in the second resource of PDSCH 1, it is considered that PDSCH 1 does not carry the first DCI, and the UE does not need to detect DCI in the remaining resources of PDSCH 1.

[0075] The above three methods can be used individually or in combination. For example, combining method (1) and method (3), the reference signal within a PDSCH indicates whether it includes the first DCI. The UE determines whether the PDSCH includes the first DCI based on the indication of the reference signal. If the reference signal indicates that the first DCI is included, the UE receives the first DCI in the second resource of this PDSCH. As another example, combining method (2) and method (3), the UE determines whether the first DCI is included through the CRC detection result within the first resource of a PDSCH. If the CRC within the first resource passes, the UE receives the first DCI in the second resource of this PDSCH.

[0076] The first configuration information is used to configure the parameters of at least one second downlink channel, which is used to carry scheduling signaling.

[0077] In some embodiments, scheduling signaling carried by at least one second downlink channel instructs the UE to receive (or schedule) a traffic channel, or a shared channel (such as PDSCH and / or PUSCH), or a data channel, or a multicast channel, or a control channel (such as PDCCH).

[0078] In some embodiments, the scheduling signaling carried by at least one second downlink channel includes DCI.

[0079] In some embodiments, if the first configuration information is not effective, the UE further performs one or more of the following steps: not receiving at least one second downlink channel; not detecting at least one second downlink channel; not receiving at least one second downlink channel according to the first configuration information; not detecting at least one second downlink channel according to the first configuration information; receiving at least one second downlink channel according to the second configuration information; detecting at least one second downlink channel according to the second configuration information. The UE may perform only one of these steps, or perform multiple of these steps. For example, the UE neither receives nor detects at least one second downlink channel. Another example is that the UE neither receives nor detects at least one second downlink channel according to the first configuration information. Yet another example is that the UE neither receives at least one second downlink channel according to the first configuration information, but receives at least one second downlink channel according to the second configuration information. Yet another example is that the UE neither detects at least one second downlink channel according to the first configuration information, but detects at least one second downlink channel according to the second configuration information. Yet another example is that the UE neither receives at least one second downlink channel according to the first configuration information, but receives and detects at least one second downlink channel according to the second configuration information.

[0080] The second configuration information is used to configure parameters of at least one second downlink channel, and the second configuration information differs from the first configuration information. The second configuration information is agreed upon by the communication protocol, configured by the network device (e.g., through configuration signaling), or pre-configured (e.g., through predefined codes, CG, or RRC signaling).

[0081] In some embodiments, the second configuration information is effective for the UE within a first time period.

[0082] In some embodiments, within the first time resource, the number of detection opportunities corresponding to the second configuration information is less than the number of detection opportunities corresponding to the first configuration information; and / or, within the first time resource, the number of detections corresponding to the second configuration information is less than the number of detections corresponding to the first configuration information. For example, assuming that when the UE uses the second configuration information to receive at least one second downlink channel, the number of detection opportunities within the first time resource is X1, and when the UE uses the first configuration information to receive at least one second downlink channel, the number of detection opportunities within the first time resource is X2, where X1 is less than X2. As another example, assuming that when the UE uses the second configuration information to receive at least one second downlink channel, the number of detections within the first time resource is X3, and when the UE uses the first configuration information to receive at least one second downlink channel, the number of detections within the first time resource is X4, where X3 is less than X4.

[0083] In some embodiments, the second configuration information and the first configuration information satisfy one or more of the following:

[0084] • The period corresponding to the second configuration information is longer than the period corresponding to the first configuration information;

[0085] The number of search spaces corresponding to the second configuration information is less than the number of search spaces corresponding to the first configuration information;

[0086] • The number of candidate channels (such as PDCCH Candidate) corresponding to the second configuration information is less than the number of candidate channels corresponding to the first configuration information;

[0087] • The candidate channels corresponding to the first configuration information include the candidate channels corresponding to the second configuration information. In other words, the candidate channels corresponding to the second configuration information are a subset of the candidate channels corresponding to the first configuration information.

[0088] • The number of DCI formats corresponding to the second configuration information is less than the number of DCI formats corresponding to the first configuration information;

[0089] • The number of Radio Network Temporary Identity (RNTI) types corresponding to the second configuration information is less than the number of RNTI types corresponding to the first configuration information;

[0090] The parameters corresponding to the first configuration information include the parameters corresponding to the second configuration information. In other words, the parameters corresponding to the second configuration information are a subset of the parameters corresponding to the first configuration information.

[0091] • The transmission resources corresponding to the first configuration information include the transmission resources corresponding to the second configuration information. In other words, the transmission resources corresponding to the second configuration information are a subset of the transmission resources corresponding to the first configuration information.

[0092] The second configuration information and the first configuration information can satisfy any one or more of the above conditions. For example, the period corresponding to the second configuration information is greater than the period corresponding to the first configuration information, and the number of search spaces corresponding to the second configuration information is less than the number of search spaces corresponding to the first configuration information. Another example is that the number of search spaces corresponding to the second configuration information is less than the number of search spaces corresponding to the first configuration information, and the number of candidate channels corresponding to the second configuration information is less than the number of candidate channels corresponding to the first configuration information. Yet another example is that the candidate channels corresponding to the second configuration information are a subset of the candidate channels corresponding to the first configuration information, and the period corresponding to the second configuration information is greater than the period corresponding to the first configuration information. Yet another example is that the number of DCI formats corresponding to the second configuration information is less than the number of DCI formats corresponding to the first configuration information, and the number of RNTI types corresponding to the second configuration information is less than the number of RNTI types corresponding to the first configuration information. Yet another example is that the parameters corresponding to the second configuration information are a subset of the parameters corresponding to the first configuration information, and the transmission resources corresponding to the second configuration information are a subset of the transmission resources corresponding to the first configuration information. For example, the number of search spaces corresponding to the second configuration information is less than the number of search spaces corresponding to the first configuration information, and the number of DCI formats corresponding to the second configuration information is less than the number of DCI formats corresponding to the first configuration information, and the transmission resources corresponding to the second configuration information are a subset of the transmission resources corresponding to the first configuration information. For example, the number of candidate channels corresponding to the second configuration information is less than the number of candidate channels corresponding to the first configuration information, and the number of RNTI types corresponding to the second configuration information is less than the number of RNTI types corresponding to the first configuration information, and the period corresponding to the second configuration information is greater than the period corresponding to the first configuration information. For example, the period corresponding to the second configuration information is greater than the period corresponding to the first configuration information, and the number of candidate channels corresponding to the second configuration information is less than the number of candidate channels corresponding to the first configuration information, and the parameters corresponding to the second configuration information are a subset of the parameters corresponding to the first configuration information, and the transmission resources corresponding to the second configuration information are a subset of the transmission resources corresponding to the first configuration information. It is impossible to list all combinations here, but it should be understood that the embodiments of this application support any two or more of the above combinations.

[0093] in:

[0094] The period corresponding to the second configuration information is greater than the period corresponding to the first configuration information. For example, the period corresponding to the second configuration information is A times the period corresponding to the first configuration information (A > 1). Alternatively, there is no multiple relationship between the period corresponding to the second configuration information and the period corresponding to the first configuration information; it is sufficient that the period corresponding to the second configuration information is greater than the period corresponding to the first configuration information. Therefore, the detection interval corresponding to the second configuration information is greater than the detection interval corresponding to the first configuration information.

[0095] The number of search spaces corresponding to the second configuration information is less than the number of search spaces corresponding to the first configuration information. For example, if the first configuration information corresponds to B1 public search spaces and / or C1 UE-specific search spaces, and the second configuration information corresponds to B2 public search spaces and / or C2 UE-specific search spaces, then B1 < B2 and C1 < C2, or B1 ≤ B2 and C1 < C2, or B1 < B2 and C1 ≤ C2, or (B1 + C1) < (C1 + C2). The number of search spaces corresponding to the second configuration information is the number of search spaces in at least one second downlink channel when the UE uses the second configuration information. The number of search spaces corresponding to the first configuration information is the number of search spaces in at least one second downlink channel when the UE uses the first configuration information.

[0096] The candidate channel corresponding to the second configuration information is, when the UE uses the second configuration information, at least one candidate channel (such as PDCCH Candidate) in the second downlink channel. The candidate channel corresponding to the first configuration information is, when the UE uses the first configuration information, at least one candidate channel (such as PDCCH Candidate) in the second downlink channel.

[0097] The number of DCI formats corresponding to the second configuration information is less than the number of DCI formats corresponding to the first configuration information. In one case, the DCI formats corresponding to the second configuration information are a subset of the DCI formats corresponding to the first configuration information; in another case, the DCI formats corresponding to the second configuration information are partially the same as or completely different from the DCI formats corresponding to the first configuration information, and the number of DCI formats corresponding to the first configuration information is greater than the number of DCI formats corresponding to the second configuration information. For example, the DCI formats corresponding to the second configuration information only include the fallback mode DCI formats of DCI format 1 or DCI format 2, or only include the mandatory DCI formats, or only include single-codeword scheduled DCI formats (such as DCI format 1_0 or 0_1). The DCI formats corresponding to the second configuration information are the DCI formats that the UE receives and / or detects on at least one second downlink channel when using the second configuration information. The DCI formats corresponding to the first configuration information are the DCI formats that the UE receives and / or detects on at least one second downlink channel when using the first configuration information.

[0098] The number of RNTI types corresponding to the second configuration information is less than the number of RNTI types corresponding to the first configuration information. In one scenario, the RNTI types corresponding to the second configuration information are a subset of the RNTI types corresponding to the first configuration information; in another scenario, the RNTI types corresponding to the second configuration information are partially the same as or completely different from the RNTI types corresponding to the first configuration information, and the number of RNTI types corresponding to the first configuration information is greater than the number of RNTI types corresponding to the second configuration information. For example, the RNTI types corresponding to the first configuration information include cell RNTIs (C-RNTI), modulation and coding scheme cell RNTIs (MCS-C-RNTI), and configured scheduling RNTIs (CS-RNTI) used for scheduling PDSCH and / or the Physical Uplink Shared Channel (PUSCH), while the second configuration information does not need to include these RNTIs. The RNTI types corresponding to the first configuration information are the RNTI types that the UE receives and / or detects on at least one second downlink channel when using the first configuration information. The RNTI type corresponding to the second configuration information is the RNTI type that the UE receives and / or detects on at least one second downlink channel when using the second configuration information.

[0099] The transmission resources corresponding to the first configuration information are the transmission resources that the UE receives and / or detects on at least one second downlink channel when using the first configuration information. The transmission resources corresponding to the second configuration information are the transmission resources that the UE receives and / or detects on at least one second downlink channel when using the second configuration information.

[0100] In some embodiments, the first configuration information includes complete configuration information for at least one second downlink channel, and the second configuration information also includes complete configuration information for at least one second downlink channel. Alternatively, the first configuration information includes complete configuration information for at least one second downlink channel, and the second configuration information includes partial configuration information for at least one second downlink channel, such as differentiated configuration information based on the first configuration information (also known as differential information or supplementary information). That is, the second configuration information may only include configuration information that is different from the first configuration information, or the offset between the second and first configuration information. When using the second configuration information, the UE needs to combine the first configuration information to determine the complete configuration for at least one second downlink channel.

[0101] In some embodiments, the first time resource is related to at least one first downlink channel and can be implemented in the following two ways:

[0102] Method (i): The first time resources include the time unit in which at least one first downlink channel is located or the time resources occupied by at least one first downlink channel.

[0103] If the first time resource includes a time unit containing at least one first downlink channel, it means that the first configuration information is not effective within the time unit containing at least one first downlink channel. If the first time resource includes time resources occupied by at least one first downlink channel, it means that the first configuration information is not effective within the time resources occupied by at least one first downlink channel. In some embodiments, the time resources occupied by at least one first downlink channel may be continuous resources.

[0104] If the first configuration information is ineffective, the steps performed by the UE are as described above. For example, taking the first downlink channel as PDSCH and the second downlink channel as PDCCH as an example, within the time unit containing at least one PDSCH, the UE uses the second configuration information to receive at least one PDCCH and / or does not use the first configuration information to receive at least one PDCCH. Reducing or abandoning blind detection of PDCCH within the time unit containing at least one PDSCH can effectively reduce the UE's blind detection power consumption.

[0105] In this configuration, at least one first downlink channel includes a semi-persistently scheduled downlink channel, such as SPS-PDSCH. Alternatively, at least one first downlink channel includes a downlink channel scheduled by a second DCI. The DCI that schedules multiple data channels at once has high reliability, and embedding subsequent scheduling information into the PDSCH scheduled by this DCI for transmission will not cause a significant reduction in subsequent scheduling performance.

[0106] The second DCI is transmitted via a second downlink channel, or via a first downlink channel preceding at least one first downlink channel. For example, a PDCCH carries the second DCI, and the second DCI schedules at least one PDSCH. Alternatively, a PDSCH carries the second DCI, and the second DCI schedules at least one PDSCH following this PDSCH.

[0107] In some embodiments, a time unit includes one or more of the following: a symbol, a symbol group, a subframe, a frame, a time slot, and a sub-time slot.

[0108] Figure 5 illustrates a transmission diagram of a downlink channel provided in an exemplary embodiment of this application. Taking a first downlink channel as PDSCH and a second downlink channel as PDCCH as an example, assuming DCI 1 is used to schedule PDSCH 1 and PDSCH 2, PDSCH 1 is located in time slot n, and PDSCH 2 is located in time slot n+2, then the UE receives at least one PDCCH using the second configuration information in time slots n and n+2. For example, in time slots n and n+2 where PDSCH 1 and PDSCH 2 are received, the UE reduces the number of detections in the PDCCH or does not detect the PDCCH, thereby effectively reducing channel detection power consumption and benefiting energy saving on the UE side.

[0109] Method (ii): at least one first downlink channel includes a downlink channel scheduled by the second DCI, and the first time resource includes continuous time resources.

[0110] The DCI (Distributed Control Channel) that schedules multiple data channels simultaneously has high reliability. Embedding subsequent scheduling information into the PDSCH (Pulse Distribution Channel) scheduled by this DCI will not significantly degrade subsequent scheduling performance. Furthermore, reducing or abandoning blind detection of PDCCH (Pulse Distribution Channel) within at least one PDSCH time unit can effectively reduce UE blind detection power consumption.

[0111] The UE can determine the time-domain start position and / or time-domain end position of the first time resource.

[0112] Regarding the starting position of the time domain for the first-time resource:

[0113] In some embodiments, the time-domain start position of the first time resource is determined according to one or more of the following: the end position of the time unit in which the second DCI is located; the end position of the time resource occupied by the second DCI; the start position of the first first downlink channel in at least one first downlink channel; the start position of the time unit in which the first first downlink channel in at least one first downlink channel is located; the start position of the first time unit occupied by the first first downlink channel in at least one first downlink channel; the length of the first time resource and the time-domain end position of the first time resource.

[0114] For example, the time-domain start position of the first time resource is determined based on the end position of the time unit where the second DCI is located. For instance, the end position of the time unit where the second DCI is located is the time-domain start position of the first time resource, or the time-domain start position of the first time resource is located at a specific position before or after the end position of the time unit where the second DCI is located. For example, referring to Figure 5, assuming DCI 1 is the second DCI, the time-domain start position of the first time resource is located at the end position of the time slot n where DCI 1 is located.

[0115] For example, the start position of the first time resource in the time domain is determined based on the end position of the time resource occupied by the second DCI. For instance, the end position of the time resource occupied by the second DCI is the start position of the first time resource in the time domain, or the start position of the first time resource in the time domain is located at a specific position before or after the end position of the time resource occupied by the second DCI. For example, if the second DCI occupies symbols S0 to S7, the start position of the first time resource in the time domain is the end position of symbol S7. For example, if channel 1 carries the second DCI, the start position of the first time resource in the time domain is the end position of channel 1.

[0116] For example, the time-domain start position of the first time resource is determined based on the start position of the first downlink channel among at least one first downlink channel. For instance, the start position of the first PDSCH among at least one PDSCH is the time-domain start position of the first time resource, or the time-domain start position of the first time resource is located at a specific position before or after the start position of the first PDSCH. For example, referring to Figure 5, the time-domain start position of the first time resource is the start position of PDSCH 1.

[0117] For example, the time-domain start position of the first time resource is determined based on the start position of the time unit of the first first downlink channel in at least one first downlink channel. For instance, the start position of the time unit of the first PDSCH in at least one PDSCH is the time-domain start position of the first time resource, or the time-domain start position of the first time resource is located at a specific position before or after the start position of the time unit of the first PDSCH. For example, referring to Figure 5, the time-domain start position of the first time resource is the start position of the timeslot n where PDSCH 1 is located.

[0118] For example, the time-domain start position of the first time resource is determined based on the start position of the first time unit occupied by the first downlink channel in at least one first downlink channel. For instance, the start position of the first time unit occupied by the first PDSCH in at least one PDSCH is the time-domain start position of the first time resource, or the time-domain start position of the first time resource is located at a specific position before or after the start position of the first time unit occupied by the first PDSCH. For example, referring to Figure 6, at least one PDSCH includes PDSCH 1, PDSCH 2, and PDSCH 3, PDSCH 1 occupies symbols 3 to 11, and the start position of symbol 3 is the time-domain start position of the first time resource.

[0119] For example, the start position of the first time resource in the time domain is determined based on the length and end position of the first time resource in the time domain. For instance, the start position of the first time resource in the time domain can be determined by subtracting its length L from its end position E. The length of the first time resource is defined by the communication protocol, configured by the network device (e.g., through configuration signaling), or pre-configured (e.g., through predefined codes, predefined tables, CG, or RRC signaling). Assuming the length of the first time resource is L (L > 0), L can be represented by time or time units. For example, the length of the first time resource could be L seconds (s), L milliseconds (ms), L microseconds (μs), L symbols, L symbol groups, L subframes, L frames, L time slots, or L sub-time slots.

[0120] In some embodiments, the temporal starting position of the first time resource satisfies one or more of the following:

[0121] • The start position of the time domain of the first time resource is no later than the end position of the time unit in which the second DCI is located; that is, the start position of the time domain of the first time resource is earlier than or equal to the end position of the time unit in which the second DCI is located.

[0122] • The start position of the time domain of the first time resource is no later than the end position of the time resource occupied by the second DCI, that is, the start position of the time domain of the first time resource is earlier than or equal to the end position of the time resource occupied by the second DCI.

[0123] • The time-domain start position of the first time resource is no later than the start position of the first downlink channel in at least one first downlink channel. Taking the first downlink channel as a PDSCH as an example, the time-domain start position of the first time resource is earlier than or equal to the start position of the first PDSCH in at least one PDSCH.

[0124] • The time domain start position of the first time resource is no later than the start position of the time unit of the first first downlink channel in at least one first downlink channel. For example, the time domain start position of the first time resource is earlier than or equal to the start position of the time unit of the first PDSCH in at least one PDSCH.

[0125] • The time-domain start position of the first time resource is no later than the start position of the first time unit occupied by the first downlink channel in at least one first downlink channel. For example, the time-domain start position of the first time resource is earlier than or equal to the start position of the first time unit occupied by the first PDSCH in at least one PDSCH.

[0126] The time-domain start position of the first time resource can satisfy any one or more of the above conditions. For example, the time-domain start position of the first time resource is no later than the end position of the time unit where the second DCI is located and the start position of the first PDSCH. Another example is that the time-domain start position of the first time resource is no later than the end position of the time resource occupied by the second DCI and the start position of the time unit where the first PDSCH is located. Yet another example is that the time-domain start position of the first time resource is no later than the end position of the time unit where the second DCI is located and the start position of the first time unit occupied by the first PDSCH, and so on. It is impossible to list all combinations here, but it should be understood that the embodiments of this application support any two or more of the above combinations.

[0127] Regarding the end position of the time domain for the first-time resource:

[0128] In some embodiments, the time-domain end position of the first time resource is determined according to one or more of the following: the end position of the last first downlink channel in at least one first downlink channel; the end position of the time unit in which the last first downlink channel in at least one first downlink channel is located; the start position of the time unit in which the last first downlink channel in at least one first downlink channel is located; a first duration, the first duration being agreed upon by a communication protocol or configured by a network device or reported by a terminal device; the length of the first time resource; and the time-domain start position of the first time resource.

[0129] For example, the time-domain end position of the first time resource is determined based on the end position of the last first downlink channel among at least one first downlink channel. For instance, the end position of the last first downlink channel is the time-domain end position of the first time resource. For example, referring to Figure 5, the time-domain end position of the first time resource is located at the end position of PDSCH 2.

[0130] For example, the time-domain end position of the first time resource is determined based on the end position of the last first downlink channel in at least one first downlink channel and a first duration. For instance, the time-domain end position of the first time resource is located one duration before the end position of the last first downlink channel. For example, assuming the end position of the last PDSCH in at least one PDSCH is T1 and the first duration is t1, then the time-domain end position of the first time resource is T1-t1. Determining the time-domain end position of the first time resource based on the end position of the last PDSCH and the first duration allows subsequent DCI / scheduling signaling to be sent in advance before the end of the last PDSCH, reserving t1 processing time for subsequent transmissions. After the last PDSCH ends, the UE can immediately receive or transmit on subsequent channels, effectively reducing subsequent scheduling latency.

[0131] The first duration is determined by the communication protocol, configured by the network device, or reported by the UE (e.g., the UE determines and reports the first duration based on its own hardware capabilities). The first duration can be represented by time or time units, for example, the first duration is t1 seconds (s), or t1 milliseconds (ms), or t1 microseconds (μs), or t1 symbols, or t1 symbol groups, or t1 subframes, or t1 frames, or t1 time slots, or t1 sub-time slots.

[0132] For example, the time-domain end position of the first time resource is determined based on the end position of the time unit containing the last first downlink channel among at least one first downlink channel. For instance, the end position of the time unit containing the last first downlink channel is the time-domain end position of the first time resource. For example, referring to Figure 5, the end position of time slot n+2 where PDSCH 2 is located is the time-domain end position of the first time resource.

[0133] For example, the time-domain end position of the first time resource is determined based on the end position of the time unit containing the last first downlink channel in at least one first downlink channel and a first duration. For instance, the time-domain end position of the first time resource is located one duration before the end position of the time unit containing the last first downlink channel. For example, assuming the end position of the time unit containing the last PDSCH in at least one PDSCH is T2 and the first duration is t1, then the time-domain end position of the first time resource is T2-t1. Similarly, this method can also reduce subsequent scheduling delays by sending subsequent scheduling signaling in advance before the end of the time unit containing the last PDSCH, allowing subsequent channels to be transmitted immediately in the next time unit after the last PDSCH.

[0134] For example, the time-domain end position of the first time resource is determined based on the start position of the time unit containing the last first downlink channel among at least one first downlink channel. For instance, the start position of the time unit containing the last first downlink channel is the time-domain end position of the first time resource, which is also the end position of the time unit preceding the last first downlink channel. For example, referring to Figure 5, the start position of time slot n+2 containing PDSCH 2, which is also the end position of time slot n+1, is the time-domain end position of the first time resource. Therefore, this method can reduce subsequent scheduling delays, allowing subsequent channels to be transmitted immediately after the last PDSCH.

[0135] For example, the time-domain end position of the first time resource is determined based on the length and start position of the first time resource. Adding the length of the first time resource to its start position in the time domain gives the time-domain end position. In other words, the position where the start position of the first time resource is located after a length L is the time-domain end position of the first time resource. The length L of the first time resource has been described previously and will not be repeated here.

[0136] In some embodiments, the time-domain end position of the first time resource satisfies one or more of the following:

[0137] • The time domain end position of the first time resource is not later than the end position of the last first downlink channel in at least one first downlink channel. For example, the time domain end position of the first time resource is earlier than or equal to the end position of the last PDSCH in at least one PDSCH.

[0138] • The time domain end position of the first time resource is no later than the time domain position of the last first downlink channel in at least one first downlink channel for a first duration. For example, the time domain end position of the first time resource is earlier than or equal to the time domain position of the last PDSCH in at least one PDSCH for a first duration.

[0139] • The time domain end position of the first time resource is not later than the end position of the time unit in which the last first downlink channel in at least one first downlink channel is located. For example, the time domain end position of the first time resource is earlier than or equal to the end position of the time unit in which the last PDSCH in at least one PDSCH is located.

[0140] • The time domain end position of the first time resource is not later than the start position of the time unit of the last first downlink channel in at least one first downlink channel. For example, the time domain end position of the first time resource is earlier than or equal to the start position of the time unit of the last PDSCH in at least one PDSCH.

[0141] In summary, the method provided in this application ensures that the first configuration information of at least one PDCCH is ineffective within the first time resource related to at least one PDSCH received by the UE. Therefore, the UE will not use the first configuration information to perform blind detection on at least one PDCCH within the first time resource, thus reducing the number of blind PDCCH detections or even stopping blind PDCCH detection within the first time resource, which helps to achieve energy saving on the UE side. Furthermore, it provides a specific and feasible way to determine the first time resource, which helps to reduce subsequent scheduling latency and transmission latency.

[0142] Figure 7 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a network device and includes at least some of the following steps:

[0143] Step 720: Send at least one first downlink channel and / or at least one second downlink channel, wherein the at least one second downlink channel is used to carry scheduling signaling.

[0144] The network device transmits at least one first downlink channel, that is, the network device transmits downlink signals in at least one first downlink channel. The network device transmits at least one second downlink channel, that is, the network device transmits downlink signals in at least one second downlink channel.

[0145] In some embodiments, the first downlink channel includes a downlink data channel or a downlink shared channel.

[0146] In some embodiments, the second downlink channel includes a downlink control channel.

[0147] In some embodiments, the network device transmits downlink data and / or DCI in at least one first downlink channel. The DCI can also be implemented as scheduling signaling, used to schedule downlink and / or uplink data transmission. For example, at least one first downlink channel includes downlink data, and / or, one of the at least one first downlink channels includes a first DCI. Taking a PDSCH as an example, for instance, at least one PDSCH includes downlink data, and / or one of the at least one PDSCH includes a first DCI, used to schedule downlink and / or uplink data transmission. Or, for example, at least one PDSCH includes downlink data, and / or, one of the at least one PDSCH includes a first scheduling signaling, used to schedule downlink and / or uplink data transmission. The transmission resources of the PDSCH scheduled by the DCI / scheduling signaling are determined. Multiplexing subsequent DCI / scheduling information within this PDSCH according to agreed-upon rules can significantly reduce the number of blind detections by the UE.

[0148] In some embodiments, the network device also transmits a reference signal in at least one first downlink channel, the reference signal being used to indicate whether one of the first downlink channels includes a first DCI (or a first scheduling signaling). For example, the reference signal included in at least one PDSCH is used to indicate whether the PDSCH containing the reference signal includes the first DCI. As another example, the reference signal included in at least one PDSCH is used to indicate whether the next PDSCH containing the reference signal includes the first DCI.

[0149] In some embodiments, the reference signal includes one or more indicator bits, and different values ​​of the indicator bits indicate whether one of the first downlink channels includes or excludes the first DCI.

[0150] In some embodiments, the cyclic shift information used by the reference signal indicates whether one of the at least one first downlink channels includes or excludes the first DCI. For example, if the reference signal uses a first cyclic shift value, it indicates that one of the at least one first downlink channels includes the first DCI; if the reference signal uses a second cyclic shift value, it indicates that one of the at least one first downlink channels does not include the first DCI. The mapping relationship between the cyclic shift information and whether the first DCI is included is agreed upon by the communication protocol, configured by the network device (e.g., configured through configuration signaling), or pre-configured (e.g., implemented through predefined codes, predefined tables, CG, or RRC signaling).

[0151] In some embodiments, the OCC sequence used by the reference signal indicates whether one of the first downlink channels in at least one first downlink channel includes or excludes the first DCI. For example, if the reference signal uses a first OCC sequence, it indicates that one of the first downlink channels in at least one first downlink channel includes the first DCI; if the reference signal uses a second OCC sequence, it indicates that one of the first downlink channels in at least one first downlink channel does not include the first DCI. The mapping relationship between the OCC sequence and whether the first DCI is included is agreed upon by the communication protocol, configured by the network device (e.g., configured through configuration signaling), or pre-configured (e.g., implemented through predefined codes, predefined tables, CG, or RRC signaling).

[0152] In some embodiments, the detection result (e.g., CRC detection result) of a first resource in at least one first downlink channel is used to indicate whether the first downlink channel includes a first DCI (or a first scheduling signaling). The first resource is defined by a communication protocol, configured by a network device (e.g., through configuration signaling), or pre-configured (e.g., through predefined codes, CG, or RRC signaling). Therefore, the UE can determine whether the first downlink channel carries a first DCI based on the detection result of the first resource in a first downlink channel.

[0153] In some embodiments, the first DCI (or first scheduling signaling) is transmitted within a second resource in one of the at least one first downlink channels. The second resource is defined by the communication protocol, configured by the network device (e.g., via configuration signaling), or pre-configured (e.g., via predefined codes, CG, or RRC signaling). Therefore, the first DCI is transmitted only within a fixed resource. The UE can identify whether a first downlink channel includes the first DCI by detecting it only within the fixed resource of that first downlink channel. By limiting the resources used by the first DCI, the power consumption required for DCI detection is effectively reduced.

[0154] The first configuration information is used to configure the parameters of at least one second downlink channel.

[0155] In some embodiments, scheduling signaling carried by at least one second downlink channel instructs the UE to receive (or schedule) a traffic channel, or a shared channel (such as PDSCH and / or PUSCH), or a data channel, or a multicast channel, or a control channel (such as PDCCH).

[0156] In some embodiments, the scheduling signaling carried by at least one second downlink channel includes DCI.

[0157] In some embodiments, the first configuration information is not effective on the UE side within a first time resource related to at least one first downlink channel. That is, within the first time resource, the parameters of at least one second downlink channel configured by the first configuration information are ineffective for the UE. Therefore, when the first configuration information is ineffective, the UE cannot use the parameters configured by the first configuration information to receive and / or detect at least one second downlink channel. The first configuration information is agreed upon by the communication protocol, configured by the network device (e.g., configured via configuration signaling), or pre-configured. If the first configuration information is pre-configured, it may be implemented, for example, by pre-storing corresponding codes, tables, or other means that can be used to indicate relevant information in the UE, or by configuring authorization, or by using RRC signaling sent by the network device.

[0158] In some embodiments, the second configuration information takes effect on the UE side within the first time resource. That is, within the first time resource, the parameters of at least one second downlink channel configured by the second configuration information are effective for the UE. Therefore, the UE can use the parameters configured by the second configuration information to receive and / or detect at least one second downlink channel. The second configuration information is used to configure the parameters of at least one second downlink channel, and the second configuration information is different from the first configuration information. The second configuration information is agreed upon by the communication protocol, configured by the network device (e.g., configured through configuration signaling), or pre-configured (e.g., implemented through predefined codes, CG, or RRC signaling).

[0159] In some embodiments, within the first time resource, the number of detection opportunities corresponding to the second configuration information is less than the number of detection opportunities corresponding to the first configuration information; and / or, within the first time resource, the number of detections corresponding to the second configuration information is less than the number of detections corresponding to the first configuration information.

[0160] In some embodiments, the second configuration information and the first configuration information satisfy one or more of the following: the period corresponding to the second configuration information is greater than the period corresponding to the first configuration information; the number of search spaces corresponding to the second configuration information is less than the number of search spaces corresponding to the first configuration information; the number of candidate channels (such as PDCCH Candidates) corresponding to the second configuration information is less than the number of candidate channels corresponding to the first configuration information; the candidate channels corresponding to the first configuration information include the candidate channels corresponding to the second configuration information, or it can be understood that the candidate channels corresponding to the second configuration information are a subset of the candidate channels corresponding to the first configuration information; the number of DCI formats corresponding to the second configuration information is less than the number of DCI formats corresponding to the first configuration information; the number of RNTI types corresponding to the second configuration information is less than the number of RNTI types corresponding to the first configuration information; the parameters corresponding to the first configuration information include the parameters corresponding to the second configuration information, or it can be understood that the parameters corresponding to the second configuration information are a subset of the parameters corresponding to the first configuration information; the transmission resources corresponding to the first configuration information include the transmission resources corresponding to the second configuration information, or it can be understood that the transmission resources corresponding to the second configuration information are a subset of the transmission resources corresponding to the first configuration information.

[0161] For example, the period corresponding to the second configuration information is A times the period corresponding to the first configuration information (A > 1). Alternatively, there may be no multiple relationship between the period corresponding to the second configuration information and the period corresponding to the first configuration information; it is sufficient that the period corresponding to the second configuration information is greater than the period corresponding to the first configuration information. Therefore, the detection interval corresponding to the second configuration information is greater than the detection interval corresponding to the first configuration information.

[0162] For example, if the first configuration information corresponds to B1 public search spaces and / or C1 UE-specific search spaces, and the second configuration information corresponds to B2 public search spaces and / or C2 UE-specific search spaces, then B1 < B2 and C1 < C2, or B1 ≤ B2 and C1 < C2, or B1 < B2 and C1 ≤ C2, or (B1 + C1) < (C1 + C2).

[0163] For example, the DCI format corresponding to the second configuration information is a subset of the DCI format corresponding to the first configuration information; or, the DCI format corresponding to the second configuration information is partially the same as or completely different from the DCI format corresponding to the first configuration information, and the number of DCI formats corresponding to the first configuration information is greater than the number of DCI formats corresponding to the second configuration information. For example, the DCI format corresponding to the second configuration information only includes the DCI formats in fallback mode of DCI format1 or DCI format2, or, the DCI format corresponding to the second configuration information only includes the mandatory DCI formats, or, the DCI format corresponding to the second configuration information only includes the DCI formats with single codeword scheduling (such as DCI format 1_0 or 0_1).

[0164] For example, the RNTI type corresponding to the second configuration information is a subset of the RNTI type corresponding to the first configuration information; or, the RNTI type corresponding to the second configuration information is partially the same as or completely different from the RNTI type corresponding to the first configuration information, and the number of RNTI types corresponding to the first configuration information is greater than the number of RNTI types corresponding to the second configuration information. For example, the RNTI types corresponding to the first configuration information include C-RNTI, MCS-C-RNTI, and CS-RNTI used for scheduling PDSCH and / or PUSCH, while the second configuration information does not need to include these RNTIs.

[0165] In some embodiments, the first configuration information includes complete configuration information for at least one second downlink channel, and the second configuration information also includes complete configuration information for at least one second downlink channel. Alternatively, the first configuration information includes complete configuration information for at least one second downlink channel, and the second configuration information includes partial configuration information for at least one second downlink channel, such as differentiated configuration information based on the first configuration information (also known as differential information or supplementary information). That is, the second configuration information may only include configuration information that is different from the first configuration information, or the offset between the second and first configuration information. When using the second configuration information, the UE needs to combine the first configuration information to determine the complete configuration for at least one second downlink channel.

[0166] The first time resource is related to at least one first downlink channel. For example, the first time resource is determined based on at least one first downlink channel, or the time domain location of the first time resource is associated with the time domain location of at least one first downlink channel.

[0167] In some embodiments, the first time resource includes the time unit containing at least one first downlink channel or the time resource occupied by at least one first downlink channel. The at least one first downlink channel includes a semi-persistently scheduled downlink channel, such as SPS-PDSCH, or the at least one first downlink channel includes a downlink channel scheduled by a second DCI. The second DCI is transmitted via a second downlink channel or via a first downlink channel preceding at least one first downlink channel. For example, a PDCCH carries the second DCI, and the second DCI schedules at least one PDSCH. Alternatively, a PDSCH carries the second DCI, and the second DCI schedules at least one PDSCH following this PDSCH.

[0168] In some embodiments, at least one first downlink channel includes a downlink channel scheduled by a second DCI, and the first time resource includes continuous time resources.

[0169] In some embodiments, the network device transmits the second DCI on a second downlink channel, or transmits the second DCI on a first downlink channel preceding the at least one first downlink channel.

[0170] In some embodiments, the first-time resource is determined by the UE, or by the network device, or by both the network device and the UE.

[0171] In some embodiments, the time-domain start position of the first time resource is determined according to one or more of the following: the end position of the time unit in which the second DCI is located; the end position of the time resource occupied by the second DCI; the start position of the first first downlink channel in at least one first downlink channel; the start position of the time unit in which the first first downlink channel in at least one first downlink channel is located; the start position of the first time unit occupied by the first first downlink channel in at least one first downlink channel; the length of the first time resource and the time-domain end position of the first time resource.

[0172] In some embodiments, the time-domain end position of the first time resource is determined according to one or more of the following: the end position of the last first downlink channel in at least one first downlink channel; the end position of the time unit in which the last first downlink channel in at least one first downlink channel is located; the start position of the time unit in which the last first downlink channel in at least one first downlink channel is located; a first duration, the first duration being agreed upon by a communication protocol or configured by a network device or reported by a terminal device; the length of the first time resource; and the time-domain start position of the first time resource.

[0173] The relevant content in the embodiments of this application can be further referred to the embodiment shown in Figure 3, and will not be repeated here.

[0174] In this embodiment of the application, the UE can be the terminal device 120 shown in FIG1, and the network device can be the network device 110 shown in FIG1.

[0175] In summary, the method provided in this application involves a network device sending at least one first downlink channel and / or at least one second downlink channel to a UE. Furthermore, within a first time resource related to the at least one first downlink channel received by the UE, the first configuration information for at least one second downlink channel is not effective for the UE. Therefore, the UE will not use the first configuration information to receive at least one second downlink channel within the first time resource, which can reduce or even eliminate the UE's detection of the second downlink channel within the first time resource, thus contributing to energy saving on the UE side.

[0176] Specifically, for scenarios or UEs that do not support scheduling signaling updates, the UE processes multiple channels serially. Before the downlink data transmission scheduled by the network device is completed, the network device may not send subsequent scheduling signaling (at least for downlink data, and possibly also for uplink data). In other words, the processing of later-scheduled channels will not be earlier than that of earlier-scheduled channels. During the time the UE processes the earlier-scheduled channels, the UE can completely or partially abandon blind detection of the downlink control channels to save power.

[0177] Figure 8 shows a structural block diagram of a communication device provided in an exemplary embodiment of this application. This device can be implemented as the UE described above, or as part of the UE described above. The device includes a receiving module 810.

[0178] The receiving module 810 is used to receive at least one first downlink channel, that is, to receive downlink signals in at least one first downlink channel.

[0179] In some embodiments, the apparatus further includes a processing module 830, configured to determine that the first configuration information is ineffective within a first time resource associated with the at least one first downlink channel. The first configuration information is used to configure parameters of at least one second downlink channel, which is used to carry scheduling signaling.

[0180] In some embodiments, the receiving module 810 is further configured to: receive downlink data in the at least one first downlink channel; and / or receive a first DCI in one of the at least one first downlink channels. The first DCI is used to schedule subsequent downlink data transmission and / or uplink data transmission.

[0181] In some embodiments, the receiving module 810 is further configured to receive a reference signal in the at least one first downlink channel, the reference signal being configured to indicate whether one of the at least one first downlink channels includes the first DCI.

[0182] In some embodiments, the receiving module 810 or the processing module 830 is further configured to: determine whether the first downlink channel includes the first DCI based on the detection result of the first resource in one of the at least one first downlink channels. For example, determining whether the PDSCH includes the first DCI based on the CRC check result of the first resource in one of the at least one PDSCH.

[0183] In some embodiments, the receiving module 810 is further configured to receive the first DCI within a second resource in one of the at least one first downlink channels. The second resource is defined by a communication protocol or configured or pre-configured by a network device.

[0184] In some embodiments, when the first configuration information is not effective, the receiving module 810 is further configured to perform one or more of the following:

[0185] The at least one second downlink channel is not received; the at least one second downlink channel is not detected; the at least one second downlink channel is not received according to the first configuration information; the at least one second downlink channel is not detected according to the first configuration information; the at least one second downlink channel is received according to the second configuration information; the at least one second downlink channel is detected according to the second configuration information.

[0186] The second configuration information is used to configure the parameters of the at least one second downlink channel, and the second configuration information is different from the first configuration information.

[0187] In some embodiments, within the first time resource, the number of detection opportunities corresponding to the second configuration information is less than the number of detection opportunities corresponding to the first configuration information; and / or, within the first time resource, the number of detections corresponding to the second configuration information is less than the number of detections corresponding to the first configuration information.

[0188] In some embodiments, the second configuration information and the first configuration information satisfy one or more of the following: the period corresponding to the second configuration information is greater than the period corresponding to the first configuration information; the number of search spaces corresponding to the second configuration information is less than the number of search spaces corresponding to the first configuration information; the number of candidate channels corresponding to the second configuration information is less than the number of candidate channels corresponding to the first configuration information; the candidate channels corresponding to the first configuration information include the candidate channels corresponding to the second configuration information; the number of DCI formats corresponding to the second configuration information is less than the number of DCI formats corresponding to the first configuration information; the number of Radio Network Temporary Identifier (RNTI) types corresponding to the second configuration information is less than the number of RNTI types corresponding to the first configuration information; the parameters corresponding to the second configuration information are a subset of the parameters corresponding to the first configuration information; and the transmission resources corresponding to the second configuration information are a subset of the transmission resources corresponding to the first configuration information.

[0189] In some embodiments, the first configuration information includes complete configuration information for at least one second downlink channel, and the second configuration information also includes complete configuration information for at least one second downlink channel. Alternatively, the first configuration information includes complete configuration information for at least one second downlink channel, and the second configuration information includes partial configuration information for at least one second downlink channel, such as differentiated configuration information based on the first configuration information (also known as differential information or supplementary information). That is, the second configuration information may only include configuration information that is different from the first configuration information, or the offset between the second and first configuration information. When using the second configuration information, the UE needs to combine the first configuration information to determine the complete configuration for at least one second downlink channel.

[0190] In some embodiments, the receiving module 810 is further configured to receive the first configuration information and / or the second configuration information.

[0191] In some embodiments, the first configuration information is agreed upon by the communication protocol or pre-configured.

[0192] In some embodiments, the second configuration information is agreed upon by the communication protocol or pre-configured.

[0193] In some embodiments, the at least one first downlink channel includes a semi-persistently scheduled downlink channel; or, the at least one first downlink channel includes a second DCI-scheduled downlink channel.

[0194] In some embodiments, the receiving module 810 is further configured to receive the second DCI on a second downlink channel, or to receive the second DCI on a first downlink channel preceding the at least one first downlink channel.

[0195] In some embodiments, the processing module 830 is further configured to determine the time domain start position and / or time domain end position of the first time resource.

[0196] In some embodiments, the processing module 830 determines the time-domain start position of the first time resource based on any one of the following: the end position of the time unit in which the second DCI is located; the end position of the time resource occupied by the second DCI; the start position of the first downlink channel in the at least one first downlink channel; the start position of the time unit in which the first downlink channel in the at least one first downlink channel is located; the start position of the first time unit occupied by the first downlink channel in the at least one first downlink channel; the length of the first time resource; and the time-domain end position of the first time resource.

[0197] In some embodiments, the time-domain start position of the first time resource satisfies one or more of the following: the time-domain start position of the first time resource is not later than the end position of the time unit in which the second DCI is located; the time-domain start position of the first time resource is not later than the end position of the time resource occupied by the second DCI; the time-domain start position of the first time resource is not later than the start position of the first first downlink channel in the at least one first downlink channel; the time-domain start position of the first time resource is not later than the start position of the time unit in which the first first downlink channel in the at least one first downlink channel is located; the time-domain start position of the first time resource is not later than the start position of the first time unit occupied by the first first downlink channel in the at least one first downlink channel.

[0198] In some embodiments, the processing module 830 determines the time-domain end position of the first time resource based on one or more of the following: the end position of the last first downlink channel in the at least one first downlink channel; the end position of the time unit in which the last first downlink channel in the at least one first downlink channel is located; the start position of the time unit in which the last first downlink channel in the at least one first downlink channel is located; a first duration, the first duration being agreed upon by a communication protocol or configured by a network device or reported by the terminal device; the length of the first time resource; and the time-domain start position of the first time resource.

[0199] In some embodiments, the time-domain end position of the first time resource satisfies one or more of the following: the time-domain end position of the first time resource is not later than the end position of the last first downlink channel in the at least one first downlink channel; the time-domain end position of the first time resource is not later than a time-domain position for a first duration before the end position of the last first downlink channel in the at least one first downlink channel; the time-domain end position of the first time resource is not later than the end position of the time unit in which the last first downlink channel in the at least one first downlink channel is located; the time-domain end position of the first time resource is not later than a time-domain position for a first duration before the start position of the time unit in which the last first downlink channel in the at least one first downlink channel is located.

[0200] In some embodiments, the first time resource includes the time unit in which the at least one first downlink channel is located; or, the first time resource includes the time resource occupied by the at least one first downlink channel.

[0201] In some embodiments, the first downlink channel includes a downlink data channel or a downlink shared channel.

[0202] In some embodiments, the second downlink channel includes a downlink control channel.

[0203] In some embodiments, the apparatus further includes a transmitting module 850 for transmitting uplink signals on an uplink channel. The uplink channel includes one or more of the following: a random access channel, an uplink data channel, an uplink shared channel, an uplink traffic channel, and an uplink control channel. For example, the transmitting module 850 transmits random access signals on the random access channel, transmits uplink data on the uplink data channel, the uplink shared channel, or the uplink traffic channel, and transmits uplink control information and / or uplink reports and / or acknowledgment signaling (such as ACK / NACK) on the uplink control channel.

[0204] In some embodiments, the sending module 850 is used to send uplink data based on the scheduling of the first DCI and / or the second DCI.

[0205] In some embodiments, the receiving module 810 is further configured to receive downlink data scheduled by the first DCI and / or the second DCI.

[0206] For the steps performed by the receiving module 810, processing module 830, and sending module 850, please refer to one or more steps performed by the UE in the embodiments shown in Figures 2 to 7 above. The relevant content described in the various embodiments above is also applicable to the device shown in Figure 8, and will not be repeated here.

[0207] In summary, the apparatus provided in this application embodiment does not have the first configuration information of at least one second downlink channel effective within the first time resource related to at least one first downlink channel. Therefore, the apparatus will not use the first configuration information to receive at least one second downlink channel within the first time resource, which can reduce or even abandon the detection of the second downlink channel within the first time resource and help save power consumption.

[0208] Figure 9 shows a structural block diagram of a communication device provided in an exemplary embodiment of this application. This device can be implemented as a network device as described above, or as part of a network device as described above. The device includes a transmitting module 910.

[0209] The transmitting module 910 is used to transmit at least one first downlink channel and / or at least one second downlink channel, wherein the at least one second downlink channel is used to carry scheduling signaling.

[0210] In some embodiments, the transmitting module 910 is configured to transmit downlink signals in at least one first downlink channel and / or transmit downlink signals in at least one second downlink channel.

[0211] In some embodiments, the first downlink channel includes a downlink data channel or a downlink shared channel.

[0212] In some embodiments, the second downlink channel includes a downlink control channel.

[0213] In some embodiments, the transmitting module 910 is further configured to transmit downlink data and / or DCI in the at least one first downlink channel. The DCI can also be implemented as scheduling signaling, and the DCI / scheduling signaling is used to schedule downlink data transmission and / or uplink data transmission. For example, at least one first downlink channel includes downlink data, and / or, one of the at least one first downlink channels includes a first DCI. Taking a PDSCH as an example, for instance, at least one PDSCH includes downlink data, and / or one of the at least one PDSCH includes a first DCI, which is used to schedule downlink data transmission and / or uplink data transmission. Or, for instance, at least one PDSCH includes downlink data, and / or, one of the at least one PDSCH includes a first scheduling signaling, which is used to schedule downlink data transmission and / or uplink data transmission. The transmission resources of the PDSCH scheduled by the DCI / scheduling signaling are determined. Multiplexing subsequent DCI / scheduling information in this PDSCH according to agreed rules can significantly reduce the number of blind detections by the UE.

[0214] In some embodiments, the transmitting module 910 is further configured to transmit a reference signal in the at least one first downlink channel, the reference signal being used to indicate whether one of the at least one first downlink channels includes a first DCI (or a first scheduling signaling). For example, a reference signal included in at least one PDSCH is used to indicate whether the PDSCH containing the reference signal includes the first DCI. As another example, a reference signal included in at least one PDSCH is used to indicate whether the next PDSCH of the PDSCH containing the reference signal includes the first DCI.

[0215] In some embodiments, the reference signal includes one or more indicator bits, and different values ​​of the indicator bits indicate whether one of the at least one first downlink channels includes or excludes the first DCI.

[0216] In some embodiments, the cyclic shift information used by the reference signal indicates whether one of the at least one first downlink channels includes or excludes the first DCI. For example, if the reference signal uses a first cyclic shift value, it indicates that one of the at least one first downlink channels includes the first DCI; if the reference signal uses a second cyclic shift value, it indicates that one of the at least one first downlink channels does not include the first DCI. The mapping relationship between the cyclic shift information and whether the first DCI is included is agreed upon by the communication protocol, configured by the network device (e.g., configured through configuration signaling), or pre-configured (e.g., implemented through predefined codes, predefined tables, CG, or RRC signaling).

[0217] In some embodiments, the OCC sequence used by the reference signal indicates whether one of the at least one first downlink channels includes or excludes the first DCI. For example, if the reference signal uses a first OCC sequence, it indicates that one of the at least one first downlink channels includes the first DCI; if the reference signal uses a second OCC sequence, it indicates that one of the at least one first downlink channels does not include the first DCI. The mapping relationship between the OCC sequence and whether the first DCI is included is agreed upon by the communication protocol, configured by the network device (e.g., configured through configuration signaling), or pre-configured (e.g., implemented through predefined codes, predefined tables, CG, or RRC signaling).

[0218] In some embodiments, the detection result (e.g., CRC detection result) of a first resource in one of the at least one first downlink channels is used to indicate whether the first downlink channel includes a first DCI (or a first scheduling signaling). The first resource is defined by a communication protocol, configured by a network device (e.g., through configuration signaling), or pre-configured (e.g., through predefined codes, CG, or RRC signaling). Therefore, the UE can determine whether the first downlink channel carries a first DCI based on the detection result of the first resource in a first downlink channel.

[0219] In some embodiments, the transmitting module 910 is further configured to transmit the first DCI within a second resource in one of the at least one first downlink channels. The second resource is defined by a communication protocol or configured or pre-configured by a network device.

[0220] In some embodiments, the at least one first downlink channel includes a semi-persistently scheduled downlink channel; or, the at least one first downlink channel includes a second DCI-scheduled downlink channel.

[0221] In some embodiments, the transmitting module 910 is further configured to transmit first configuration information and / or second configuration information. The first configuration information is used to configure parameters of at least one second downlink channel, which is used to carry scheduling signaling. The second configuration information is used to configure parameters of the at least one second downlink channel, and the second configuration information differs from the first configuration information.

[0222] In some embodiments, the first configuration information is agreed upon by the communication protocol or pre-configured.

[0223] In some embodiments, the second configuration information is agreed upon by the communication protocol or pre-configured.

[0224] In some embodiments, the first configuration information is not effective on the UE side within a first time resource related to at least one first downlink channel. That is, within the first time resource, the parameters of at least one second downlink channel configured by the first configuration information are ineffective for the UE. Therefore, when the first configuration information is ineffective, the UE cannot use the parameters configured by the first configuration information to receive and / or detect at least one second downlink channel. The first configuration information is agreed upon by the communication protocol, configured by the network device (e.g., configured via configuration signaling), or pre-configured. If the first configuration information is pre-configured, it may be implemented, for example, by pre-storing corresponding codes, tables, or other means that can be used to indicate relevant information in the UE, or by configuring authorization, or by using RRC signaling sent by the network device.

[0225] In some embodiments, the second configuration information takes effect on the UE side within the first time resource. That is, within the first time resource, the parameters of at least one second downlink channel configured by the second configuration information are effective for the UE. Therefore, the UE can use the parameters configured by the second configuration information to receive and / or detect at least one second downlink channel. The second configuration information is used to configure the parameters of at least one second downlink channel, and the second configuration information is different from the first configuration information. The second configuration information is agreed upon by the communication protocol, configured by the network device (e.g., configured through configuration signaling), or pre-configured (e.g., implemented through predefined codes, CG, or RRC signaling).

[0226] In some embodiments, within the first time resource, the number of detection opportunities corresponding to the second configuration information is less than the number of detection opportunities corresponding to the first configuration information; and / or, within the first time resource, the number of detections corresponding to the second configuration information is less than the number of detections corresponding to the first configuration information.

[0227] In some embodiments, the second configuration information and the first configuration information satisfy one or more of the following: the period corresponding to the second configuration information is greater than the period corresponding to the first configuration information; the number of search spaces corresponding to the second configuration information is less than the number of search spaces corresponding to the first configuration information; the number of candidate channels corresponding to the second configuration information is less than the number of candidate channels corresponding to the first configuration information; the candidate channels corresponding to the first configuration information include the candidate channels corresponding to the second configuration information; the number of DCI formats corresponding to the second configuration information is less than the number of DCI formats corresponding to the first configuration information; the number of Radio Network Temporary Identifier (RNTI) types corresponding to the second configuration information is less than the number of RNTI types corresponding to the first configuration information; the parameters corresponding to the second configuration information are a subset of the parameters corresponding to the first configuration information; and the transmission resources corresponding to the second configuration information are a subset of the transmission resources corresponding to the first configuration information.

[0228] In some embodiments, the first configuration information includes complete configuration information for at least one second downlink channel, and the second configuration information also includes complete configuration information for at least one second downlink channel. Alternatively, the first configuration information includes complete configuration information for at least one second downlink channel, and the second configuration information includes partial configuration information for at least one second downlink channel, such as differentiated configuration information based on the first configuration information (also known as differential information or supplementary information). That is, the second configuration information may only include configuration information that is different from the first configuration information, or the offset between the second and first configuration information. When using the second configuration information, the UE needs to combine the first configuration information to determine the complete configuration for at least one second downlink channel.

[0229] In some embodiments, the first time resource is associated with at least one first downlink channel, such as the first time resource being determined based on at least one first downlink channel, or the time-domain location of the first time resource being associated with the time-domain location of at least one first downlink channel.

[0230] In some embodiments, the first time resource includes the time unit containing at least one first downlink channel or the time resource occupied by at least one first downlink channel. The at least one first downlink channel includes a semi-persistently scheduled downlink channel, such as SPS-PDSCH, or the at least one first downlink channel includes a downlink channel scheduled by a second DCI. The second DCI is transmitted via a second downlink channel or via a first downlink channel preceding at least one first downlink channel. For example, a PDCCH carries the second DCI, and the second DCI schedules at least one PDSCH. Alternatively, a PDSCH carries the second DCI, and the second DCI schedules at least one PDSCH following this PDSCH.

[0231] In some embodiments, at least one first downlink channel includes a downlink channel scheduled by a second DCI, and the first time resource includes continuous time resources.

[0232] In some embodiments, the transmitting module 910 is further configured to transmit the second DCI in one of the at least one second downlink channels, or to transmit the second DCI in a first downlink channel preceding the at least one first downlink channel.

[0233] In some embodiments, the apparatus further includes a processing module 930, configured to determine the transmission resources of the at least one first channel and / or the at least one second channel. For example, the processing module 930 is configured to determine the time resources of the at least one first channel and / or the at least one second channel. Alternatively, the processing module 930 is configured to determine the time units occupied by the at least one first channel and / or the at least one second channel. Yet another example is that the processing module 930 is configured to determine the frequency domain resources of the at least one first channel and / or the at least one second channel.

[0234] In some embodiments, the processing module 930 is further configured to determine the bearer information of the at least one first channel and / or the at least one second channel. For example, the processing module 930 is configured to determine whether the at least one first channel and / or the at least one second channel carries one or more of the following: downlink data, DCI, scheduling signaling, configuration information, control information, etc.

[0235] In some embodiments, the processing module 930 is further configured to determine a first time resource.
