Description

Methods, devices, terminals, and network equipment for transmitting Channel State Information (CSI)

[0001] This disclosure claims priority to Chinese Patent Application No. 202411594062.X, filed with the Chinese Patent Office on November 8, 2024, entitled “Method, Apparatus, Terminal and Network Equipment for Transmitting Channel State Information (CSI)”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a method, apparatus, terminal and network device for transmitting Channel State Information (CSI). Background Technology

[0003] Discontinuous Reception (DRX) can save energy. For example, the DRX mechanism can enter a DRX ON period and a DRX OFF period according to a pre-configured cycle. During the DRX ON period, the terminal only reports Channel State Information (CSI) periodically according to the configured cycle of the Physical Uplink Control Channel (PUCCH). To further reduce latency, a wake-up signal can be used to trigger listening to the Physical Downlink Control Channel (PDCCH), at which point the terminal enters the DRX active time. In other words, under this mechanism, the terminal's PDCCH listening is no longer limited to a pre-configured cycle. Furthermore, considering that this pre-configured cycle and the wake-up signal cannot be configured simultaneously, the terminal may not be able to determine its CSI transmission behavior. Therefore, how to achieve CSI transmission between the terminal and network devices while listening for the wake-up signal is a problem that needs to be solved. Summary of the Invention

[0047] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0048] The following describes the relevant technologies involved in this disclosure:

[0049] 1) Periodic CSI reporting

[0050] As shown in Figure 1, under the DRX mechanism, the terminal only transmits and receives data during the DRX ON period. The DRX duration timer (drx-onDurationTimer) marks the start time of DRX ON. During the DRX ON period, the terminal reports periodic CSIs according to the PUCCH configuration period.

[0051] Furthermore, consider using a Paging Signaling Radio Network Temporary Identifier (PS-RNTI) to encrypt Downlink Control Information (DCI) with Cyclic Redundancy Check (CRC) (DCI with CRC scrambled by PS-RNTI, DCP) to indicate whether drx-onDurationTimer needs to be enabled. When there is no data transmission, DCP instructs drx-onDurationTimer not to be enabled, and the terminal does not wake up, thus achieving energy saving. To support periodic CSI reporting even when drx-onDurationTimer is not enabled, the following two higher-layer parameters are introduced to indicate whether non-L1-RSRP / L1-RSRP periodic CSI should be reported during the period indicated by drx-onDurationTimer when drx-onDurationTimer is not enabled.

[0052] Transmit Other Periodic CSI (ps-TransmitOtherPeriodicCSI): When DCP is configured but the associated drx-onDurationTimer is not started, a non-L1-RSRP periodic CSI is transmitted on the PUCCH for the duration indicated by drx-onDurationTimer.

[0053] Transmit Periodic L1-RSRP (ps-TransmitPeriodicL1-RSRP): When DCP is configured but the associated drx-onDurationTimer is not started, periodic CSIs are transmitted on the PUCCH for the duration indicated by drx-onDurationTimer. This is the configuration to transmit periodic CSIs that is L1-RSRP on the PUCCH during the time duration indicated by drx-onDurationTimer.

[0054] 2) Low Power Wake Up Signal (LP-WUS) and Low Power Wake Up Receiver (LP-WUR)

[0055] To reduce latency, LP-WUS is considered as a new timer to monitor the PDCCH. When LP-WUS triggers this new timer, the terminal enters the Connected-DRX (C-DRX) activation period. When the terminal is not in the C-DRX activation period, it falls back to LP-WUS monitoring. In this scheme, the terminal's PDCCH monitoring is no longer controlled by drx-onDurationTimer, and the terminal does not expect LP-WUS and DCP to be configured simultaneously.

[0056] This disclosure provides a method, apparatus, terminal, and network device for transmitting Channel State Information (CSI), addressing the current lack of a solution for CSI transmission between the terminal and network device when considering PDCCH monitoring triggered by a wake-up signal. The method and apparatus (or terminal or network device) are based on the same concept. Since the principles underlying the problem-solving are similar, implementations of the method and apparatus (or terminal or network device) can be mutually referenced, and repeated details will not be elaborated further.

[0057] As shown in Figure 2, an embodiment of this disclosure provides a method for transmitting Channel State Information (CSI), including the following steps:

[0058] Step 21: The terminal determines whether to send the CSI based on the first indication information carried by the first signal and / or the configuration of the first higher-layer parameters used to indicate the CSI transmission.

[0059] The first signal is generated based on the OOK waveform, and the first indication information is used to indicate whether to start the first timer for PDCCH monitoring.

[0060] Step 22: If it is determined that the CSI should be sent, the terminal sends the CSI within a first time window; wherein, the first time window is determined by whether the first timer is on and / or the configuration of the first higher layer parameter.

[0061] In this embodiment, the terminal determines whether to send the CSI based on the first indication information carried by the first signal generated based on the OOK waveform, and / or the configuration of the first higher-layer parameters used to indicate CSI transmission. That is, the terminal can determine whether to send the CSI based on the activation status of the first timer for PDCCH monitoring indicated by the first indication information, and / or the configuration of the first higher-layer parameters. If it is determined to send the CSI, the terminal sends the CSI within a first time window determined based on whether the first timer is activated and / or the configuration of the first higher-layer parameters. This ensures that the terminal can send the CSI when PDCCH monitoring is triggered by the first signal, and solves the problem that there is currently no solution for how the terminal can achieve CSI transmission with the network device when monitoring the wake-up signal.

[0062] In some embodiments, the first signal may be an LP-WUS generated based on an OOK-1 waveform or an OOK-4 waveform; or, the first signal may also be an LP-WUS generated based on an OOK-1 waveform or an OOK-4 waveform, and a payload or sequence based.

[0063] Among them, the OOK-1 waveform can be called the first type of OOK waveform, and the OOK-4 waveform can be called the second type of OOK waveform. The first type of OOK waveform and the second type of OOK waveform have different numbers of bits and / or different received sequence types for the OOK symbol carried on a single OFDM symbol. For example, the first type of OOK waveform has 1 bit and the received sequence type is a frequency domain sequence; the second type of OOK waveform has M bits (M is greater than or equal to 1) and the received sequence type is a time domain sequence.

[0064] For example, the first signal can be generated by at least one of the following configuration parameters:

[0065] The bit length of the LP-WUS signal;

[0066] Temporal location parameters; such as the correlation parameters between label-block offset (LO) and paging opportunity (PO), frame-level offset, symbol-level offset, etc.

[0067] Frequency domain location parameters; such as Physical Resource Block (PRB) indexes, etc.

[0068] OOK waveform; for example, the M value of OOK-1 and OOK-4. The M value is the number of bits of the OOK symbol carried on an Orthogonal Frequency Division Multiplexing (OFDM) symbol.

[0069] Signal type; for example, sequence-based signal types or encoding-based signal types, etc.

[0070] Encoding methods; for example: Manchester coding.

[0071] In some embodiments, the first indication information is used to indicate whether the first timer is enabled. Specifically, the first indication information may indicate that the first timer is enabled (or woken up) or that the first timer is disabled (not woken up). The first timer may be a newly defined timer; for example, whether the first timer is enabled may be indicated by the first indication information carried in LP-WUS. When the first timer is enabled, the terminal may enter the DRX activation time and perform PDCCH monitoring.

[0072] In some embodiments, the configuration status of the first higher-layer parameter may include: the first higher-layer parameter is configured (for example, the network device can notify the terminal of the configured first higher-layer parameter through higher-layer signaling), or the first higher-layer parameter is not configured.

[0073] For example, higher-layer signaling can be common or UE-specific, and this disclosure is not limited thereto.

[0074] For example, the first higher-layer parameter can be a reused existing higher-layer parameter. For instance, the first higher-layer parameter can be used to instruct the transmission of the CSI on the PUCCH resources within the time window indicated by the DRX duration timer when the DRX duration timer is not enabled. Alternatively, the first higher-layer parameter can also be a newly defined higher-layer parameter. For instance, the first higher-layer parameter can be used to instruct the transmission of the CSI on the PUCCH resources within a pre-configured time window (that is, regardless of whether the first timer and / or the DRX duration timer are enabled, the terminal can transmit the CSI on the PUCCH resources within the pre-configured time window); or, the first higher-layer parameter can be used to instruct the transmission of the CSI on the PUCCH resources of at least one of the time window indicated by the first timer, the DRX activation time, and the pre-configured time window when the first timer is enabled. This disclosure is not limited to these embodiments.

[0075] In some embodiments, before the terminal determines whether to send CSI based on the first indication information carried by the first signal, the method further includes: the terminal receiving the first signal via LP-WUR.

[0076] In some embodiments, the terminal sending the CSI within a first time window includes: the terminal sending the CSI via MR within the first time window.

[0077] For example, a terminal can receive a first signal (such as LP-WUS) sent by a network device via an LP-WUR. For instance, the network device can periodically send LP-WUS, and the period of this LP-WUS can be configured independently of C-DRX. If the terminal determines that it needs to send CSI, it can send CSI via a MR. That is, in this embodiment of the disclosure, the LP-WUR that receives LP-WUS and the MR that sends CSI can be deployed on the same terminal.

[0078] For another example, the terminal can receive a first signal (such as LP-WUS) forwarded by other terminals via LP-WUR. For instance, network devices can periodically send LP-WUS, and the period of LP-WUS can be configured independently of C-DRX. After receiving the first signal via LP-WUR, other terminals can forward it to this terminal. If the terminal determines that it needs to send CSI, it can send CSI via MR. That is, in this embodiment of the disclosure, the LP-WUR for receiving LP-WUS and the MR for sending CSI can be deployed on different terminals.

[0079] In this embodiment, the LP-WUS received by the terminal via LP-WUR can be used to determine whether the MR needs to send CSI. In some embodiments, the CSI can be a periodic CSI.

[0080] To ensure that the implementation and understanding of whether to send the CSI are consistent between the terminal and / or network device based on the first indication information carried by the first signal, and / or the configuration of the first higher-layer parameters used to indicate the CSI transmission, at least one of the following methods can be agreed upon by the protocol or pre-configured:

[0081] Method A1: In the first case where the first indication information indicates that the first timer is turned on, the CSI is sent;

[0082] Method A2: In the second case where the first high-layer parameter is configured, the CSI is sent;

[0083] Method A3: When the first indication information indicates that the first timer is started, and the configuration of the first higher layer parameter is the third case where the first higher layer parameter is configured, the CSI is sent;

[0084] Method A4: In the fourth case where the first indication information indicates that the first timer is started and the configuration of the first higher layer parameter is that the first higher layer parameter is not configured, the CSI is not sent;

[0085] Method A5: In the fifth case where the first indication information indicates that the first timer is started and the configuration of the first higher layer parameter is that the first higher layer parameter is not configured, the CSI is sent;

[0086] Method A6: In the sixth case where the first indication information indicates that the first timer is not turned on, the CSI is not sent;

[0087] Method A7: In the seventh case where the configuration of the first higher layer parameter is not configured, the CSI is not sent;

[0088] Method A8: When the first indication information indicates that the first timer is not enabled, and the configuration of the first higher layer parameter is the eighth case where the first higher layer parameter is configured, the CSI is sent;

[0089] Method A9: If the first indication information indicates that the first timer is not enabled and the configuration of the first higher layer parameter is the ninth case where the first higher layer parameter is not configured, the CSI is not sent.

[0090] Specifically, when providing terminal and / or network devices with configuration information based on the first indication information and / or the first higher-layer parameters to determine whether to send CSI, the protocol agreement or pre-configuration method can be one or more combinations of the above. The following examples illustrate this:

[0091] Example 1: Protocol-defined or pre-configured methods A1 and A6, or protocol-defined or pre-configured methods A1, A8 and A9, or protocol-defined or pre-configured methods A3, A4 and A6, or protocol-defined or pre-configured methods A3, A5 and A6, or protocol-defined or pre-configured methods A3, A4, A8 and A9, or protocol-defined or pre-configured methods A3, A5, A8 and A9, etc., are used by the terminal and / or network device to determine whether to send CSI based on the configuration of the first indication information and / or the first higher-layer parameters.

[0092] Example 2: Protocol-defined or pre-configured methods A2 and A7, or protocol-defined or pre-configured methods A2, A4 and A9, or protocol-defined or pre-configured methods A2, A5 and A9, protocol-defined or pre-configured methods A3, A8 and A7, etc., are used by the terminal and / or network device to determine whether to send CSI based on the configuration of the first indication information and / or the first higher layer parameters.

[0093] It should be noted that the above-mentioned agreement or pre-configuration method combination is an illustrative example. This disclosure does not limit the use of other combinations of the above methods A1 to A9, or include other combinations of the above methods A1 to A9, etc. This disclosure is not limited to this.

[0094] In some embodiments, the terminal determines whether to send the CSI based on first indication information carried by the first signal, and / or the configuration of first higher-layer parameters indicating CSI transmission, including one of the following:

[0095] In the first case where the first indication information indicates that the first timer is turned on, the terminal determines to send the CSI;

[0096] In the second case where the first higher-layer parameter is configured, the terminal determines to send the CSI;

[0097] When the first indication information indicates that the first timer is started, and the configuration of the first higher layer parameter is the third case where the first higher layer parameter is configured, the terminal determines to send the CSI;

[0098] In the fourth case where the first indication information indicates that the first timer is started and the configuration of the first higher layer parameter is that the first higher layer parameter is not configured, the terminal determines not to send the CSI.

[0099] In the fifth case where the first indication information indicates that the first timer is started and the configuration of the first higher layer parameter is that the first higher layer parameter is not configured, the terminal determines to send the CSI.

[0100] In some embodiments, the terminal determines whether to send the CSI based on first indication information carried by the first signal, and / or the configuration of first higher-layer parameters indicating CSI transmission, including one of the following:

[0101] In the sixth case where the first indication information indicates that the first timer is not enabled, the terminal determines not to send the CSI;

[0102] In the seventh case where the first higher-layer parameter is not configured, the terminal determines not to send the CSI;

[0103] When the first indication information indicates that the first timer is not enabled, and the configuration of the first higher layer parameter is the eighth case where the first higher layer parameter is configured, the terminal determines to send the CSI.

[0104] If the first indication information indicates that the first timer is not enabled, and the configuration of the first higher layer parameter is the ninth case where the first higher layer parameter is not configured, the terminal determines not to send the CSI.

[0105] It should be noted that when the terminal determines whether to send CSI based on the configuration of the first indication information and / or the first higher layer parameters, it can make the judgment based on one or more of the above methods A1 to A9. For example, if the protocol stipulates or pre-configures one or more of the methods A1 to A9, and the terminal determines that one of the combinations of one or more of the methods A1 to A9 is satisfied based on the configuration of the first indication information and / or the first higher layer parameters, it can determine whether to send CSI based on the satisfied one, thereby ensuring that the terminal and the network device can understand each other.

[0106] In some embodiments, in the first case, or in the second case, or in the third case, or in the fifth case, the first time window is a pre-configured time window, or the time window indicated by the first timer, or the DRX activation time;

[0107] or,

[0108] In the first case, or in the second case, or in the third case, or in the fifth case, the terminal determines the first time window based on a pre-configured time window and the time window indicated by the first timer; or, the terminal determines the first time window based on a pre-configured time window and the DRX activation time.

[0109] Specifically, in the first case, or in the second case, or in the third case, or in the fifth case, the terminal can determine the first time window in the following manner:

[0110] Method B1: The terminal determines the first time window according to the pre-configured time window; for example: the first time window is the pre-configured time window, that is, the first time window can be directly determined based on the pre-configured time window, or it can be indirectly determined based on the pre-configured time window, such as the start time, end time, or PUCCH resource location of the pre-configured time window, etc. This disclosure embodiment is not limited thereto.

[0111] or,

That is, the first time window can be directly determined based on the pre-configured time window and the time window indicated by the first timer, or it can be indirectly determined based on the pre-configured time window and the time window indicated by the first timer, such as the start time or end time of the pre-configured time window and / or the time window indicated by the first timer, or the location of the PUCCH resource, etc. This embodiment of the present disclosure is not limited thereto.

[0119] Specifically, as one implementation method: for the first, second, or fifth situation above, the first time window is a pre-configured time window, or the time window indicated by the first timer, or the DRX activation time;

[0120] Alternatively, in response to the first, second, or fifth scenario above, the terminal determines the first time window based on a pre-configured time window and the time window indicated by the first timer; or, the terminal determines the first time window based on a pre-configured time window and the DRX activation time. Specifically, the terminal can determine the first time window based on conditions, either by using a pre-configured time window and the time window indicated by the first timer, or by using a pre-configured time window and the DRX activation time. Details will be explained in subsequent embodiments.

[0121] It should be noted that, regarding the first, second, or fifth scenarios above, when the terminal determines that it needs to send CSI, it can send CSI within a pre-configured time window, or within the time window indicated by the first timer, or within the DRX activation time, or within a first time window determined by any one of the methods B1 to B5 above. Specifically, the method used to determine the first time window can be based on protocol agreement or configured by the network side to ensure consistency between the terminal side and the network device side. This disclosure embodiment is not limited to this.

[0122] Specifically, as another implementation: for the third situation above, the first time window is a pre-configured time window, or the time window indicated by the first timer; or for the third situation above, when the terminal determines that it needs to send CSI, if the first indication information indicates that the first timer is turned on, the first time window can also be the DRX activation time.

[0123] Alternatively, in the third scenario above, the terminal determines the first time window based on a pre-configured time window and the time window indicated by the first timer; or, in the third scenario above, when the terminal determines that CSI needs to be sent, if the first indication information indicates that the first timer is enabled, the terminal determines the first time window based on a pre-configured time window and the DRX activation time. Specifically, the terminal can determine the first time window based on conditions, either by using a pre-configured time window and the time window indicated by the first timer, or by using a pre-configured time window and the DRX activation time, as will be explained in subsequent embodiments.

[0124] It should be noted that, regarding the third scenario described above, when the terminal determines that it needs to send CSI, it can send CSI within a pre-configured time window, or within the time window indicated by the first timer, or within the first time window determined by any one of methods B1, B2, B3, and B5 described above; or, regarding the third scenario described above, if the first indication information indicates that the first timer is enabled, the terminal can also send CSI within a pre-configured time window, or within the time window indicated by the first timer, or within the DRX activation time, or within the first time window determined by any one of methods B1 to B5. Specifically, the method used to determine the first time window can be based on protocol agreement or configured by the network side to ensure consistency between the terminal side and the network device side; this embodiment of the disclosure is not limited to this.

[0125] In some embodiments, in the eighth case, the first time window is a pre-configured time window, or a time window indicated by a first timer;

[0126] or,

[0127] In the eighth case, the terminal determines the first time window based on the pre-configured time window and the time window indicated by the first timer.

[0128] Specifically, in the eighth case, the terminal can determine the first time window in the following way:

[0129] Method C1: The terminal determines the first time window according to the pre-configured time window; for example: the first time window is the pre-configured time window, that is, the first time window can be directly determined based on the pre-configured time window, or it can be indirectly determined based on the pre-configured time window, such as the start time, end time, or PUCCH resource location of the pre-configured time window, etc. This embodiment of the present disclosure is not limited thereto.

[0130] or,

[0131] Method C2: The terminal determines the first time window according to the time window indicated by the first timer; for example: the first time window is the time window indicated by the first timer, that is, the first time window can be directly determined based on the time window indicated by the first timer, or it can be indirectly determined based on the time window indicated by the first timer, such as the start time, end time, or PUCCH resource location of the time window indicated by the first timer, etc. This embodiment of the present disclosure is not limited thereto.

[0132] or,

[0133] Method C3: The terminal determines the first time window based on a pre-configured time window and the time window indicated by the first timer. For example, the first time window includes the pre-configured time window and the time window indicated by the first timer. That is, the first time window can be directly determined based on the pre-configured time window and the time window indicated by the first timer, or it can be indirectly determined based on the pre-configured time window and the time window indicated by the first timer, such as the start time or end time of the pre-configured time window and / or the time window indicated by the first timer, or the location of the PUCCH resource, etc. This embodiment of the present disclosure is not limited thereto.

[0134] It should be noted that, regarding the eighth scenario above, when the terminal determines that it needs to send CSI, it can send CSI within a pre-configured time window, or within the time window indicated by the first timer, or within the first time window determined by any one of the methods C1 to C3 described above. Specifically, the method used to determine the first time window can be based on protocol agreement or configured by the network side to ensure consistency between the terminal side and the network device side. This disclosure embodiment is not limited to this.

[0135] In some embodiments, the terminal sends the CSI within a first time window, including:

[0136] If PUCCH resources exist within the first time window, the terminal sends the CSI on the PUCCH resources;

[0137] The first time window is determined based on the time window indicated by the first timer; or the first time window is determined based on the DRX activation time.

[0138] For example, when a terminal determines that it needs to send a CSI, if the terminal sends the CSI within the first time window determined based on the time window indicated by the first timer (such as mode B2 or mode C2 mentioned above), the terminal needs to determine whether there is a PUCCH resource in the time window indicated by the first timer. If there is a PUCCH resource, the terminal can send the CSI on the PUCCH resource.

[0139] For another example, when the terminal determines that it needs to send CSI, if the terminal sends CSI within the first time window determined based on the DRX activation time (such as method B4 above), the terminal needs to determine whether there is a PUCCH resource for the DRX activation time. If there is a PUCCH resource, the terminal can send the CSI on the PUCCH resource.

[0140] In some embodiments, the method further includes:

[0141] If no PUCCH resource is available within the first time window, the terminal determines not to send the CSI.

[0142] The first time window is determined based on the time window indicated by the first timer; or the first time window is determined based on the DRX activation time.

[0143] For example, when a terminal determines that it needs to send a CSI, if the terminal sends the CSI within the first time window determined based on the time window indicated by the first timer (such as mode B2 or mode C2 mentioned above), the terminal needs to determine whether there is a PUCCH resource in the time window indicated by the first timer. If there is no PUCCH resource, the terminal will not send the CSI.

[0144] For another example, when the terminal determines that it needs to send CSI, if the terminal sends CSI within the first time window determined based on the DRX activation time (such as method B4 above), the terminal needs to determine whether there is a PUCCH resource for the DRX activation time. If there is a PUCCH resource, the terminal will not send the CSI.

[0145] In some embodiments, the terminal sends the CSI within a first time window, including:

[0146] If PUCCH resources exist within the time window indicated by the first timer, the terminal sends the CSI on the PUCCH resources within the pre-configured time window and on the PUCCH resources within the time window indicated by the first timer, respectively.

[0147] or,

[0148] If PUCCH resources exist during the DRX activation period, the terminal sends the CSI on PUCCH resources within the pre-configured time window and on PUCCH resources during the DRX activation period, respectively.

[0149] or,

[0150] If PUCCH resources exist within the time window indicated by the first timer, the terminal will only send the CSI on the PUCCH resources within the time window indicated by the first timer;

[0151] or,

[0152] If PUCCH resources exist during the DRX activation period, the terminal only sends the CSI on the PUCCH resources during the DRX activation period;

[0153] or,

[0154] If there is no PUCCH resource within the time window indicated by the first timer, the terminal sends CSI on the PUCCH resource within the pre-configured time window;

[0155] or,

[0156] If no PUCCH resource is available during the DRX activation period, the terminal sends a CSI on the PUCCH resource within the pre-configured time window.

[0157] For example, when a terminal determines that it needs to send a CSI, if the terminal sends a CSI within the first time window determined by the time window indicated by the first timer and the pre-configured time window (such as in method B3 or method C3 above), the terminal can send the CSI within both the time window indicated by the first timer and the pre-configured time window, or it can send the CSI only within the time window indicated by the first timer or the pre-configured time window. For example, if the terminal determines that a PUCCH resource exists within the time window indicated by the first timer, the terminal can send a CSI within both the time window indicated by the first timer and the pre-configured time window, or it can send the CSI only within the time window indicated by the first timer (for example, if the terminal sends a CSI within the time window indicated by the first timer, it does not need to send a CSI within the pre-configured time window). If the terminal determines that a PUCCH resource does not exist within the time window indicated by the first timer, the terminal will not send a CSI within the time window indicated by the first timer, but can send a CSI within the pre-configured time window.

[0158] For another example, when a terminal determines that it needs to send a CSI, if the terminal sends the CSI within the first time window determined based on the DRX activation time and the pre-configured time window (such as in method B5 above), the terminal can send the CSI within both the DRX activation time and the pre-configured time window, or it can send the CSI only within the DRX activation time or the pre-configured time window. For example, if the terminal determines that there is a PUCCH resource within the DRX activation time, the terminal can send the CSI within both the DRX activation time and the pre-configured time window, or it can send the CSI only within the DRX activation time (for example, if the terminal sends a CSI within the DRX activation time, it does not need to send a CSI within the pre-configured time window). If the terminal determines that there is no PUCCH resource within the DRX activation time, the terminal will not send the CSI within the DRX activation time, but can send the CSI within the pre-configured time window.

[0159] In some embodiments, the pre-configured time window can be determined based on an existing time window, such as the time window indicated by the DRX duration timer; or, the pre-configured time window can be a newly defined time window, such as a new time window different from the time window indicated by the DRX duration timer, or a time window specifically used for the terminal to send CSI when the terminal is listening to LP-WUS, etc., and the embodiments disclosed herein are not limited thereto.

[0160] The terminals disclosed in this embodiment can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminals may differ in different systems; for example, in a 5G system, a terminal may be called User Equipment (UE). Wireless terminals can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminals can be mobile terminals, such as mobile phones (or "cellular" phones) and computers with mobile terminals, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). The wireless terminal may also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments disclosed herein.

[0161] As shown in Figure 3, an embodiment of this disclosure provides a method for transmitting Channel State Information (CSI), including the following steps:

[0162] Step 31: The network device determines whether to receive the CSI based on the first indication information carried by the first signal and / or the configuration of the first higher-layer parameters sent by the CSI; wherein the first signal is generated based on the On / Off Keying (OOK) waveform, and the first indication information is used to indicate whether to start the first timer for monitoring the Physical Downlink Control Channel (PDCCH);

[0163] Step 32: If it is determined that the CSI is to be received, the network device receives the CSI within a first time window; wherein, the first time window is determined by whether the first timer is on and / or the configuration of the first higher layer parameter.

[0164] In some embodiments, the first higher-layer parameter is used to instruct that the CSI be sent on the PUCCH resource within the time window indicated by the DRX duration timer when the DRX duration timer is not enabled;

[0169] In some embodiments, the network device determines whether to receive the CSI based on first indication information carried by the first signal, and / or the configuration of the first higher-layer parameters used to indicate the CSI transmission, including one of the following:

[0170] In the first case where the first indication information indicates that the first timer is turned on, the network device determines to receive the CSI;

[0171] In the second case where the first higher-layer parameter is configured, the network device determines to receive the CSI;

[0172] When the first indication information indicates that the first timer is started, and the configuration of the first higher layer parameter is the third case where the first higher layer parameter is configured, the network device determines to receive the CSI;

[0173] In the fourth case where the first indication information indicates that the first timer is started and the configuration of the first higher layer parameter is that the first higher layer parameter is not configured, the network device determines that it will not receive the CSI.

[0174] In the fifth case where the first indication information indicates that the first timer is turned on and the configuration of the first higher layer parameter is that the first higher layer parameter is not configured, the network device determines to receive the CSI.

[0183] or,

[0184] The network device determines the first time window based on the pre-configured time window and the DRX activation time.

[0185] In some embodiments, the network device determines whether to receive the CSI based on first indication information carried by the first signal, and / or the configuration of the first higher-layer parameters used to indicate the CSI transmission, including one of the following:

[0186] In the sixth case where the first indication information indicates that the first timer is not enabled, the network device determines that it will not receive the CSI;

[0187] In the seventh case where the first higher-layer parameter is configured as not configured, the network device determines not to receive the CSI;

[0188] When the first indication information indicates that the first timer is not enabled, and the configuration of the first higher layer parameter is the eighth case where the first higher layer parameter is configured, the network device determines to receive the CSI.

[0189] If the first indication information indicates that the first timer is not enabled, and the configuration of the first higher layer parameter is the ninth case where the first higher layer parameter is not configured, the network device determines that it will not receive the CSI.

[0190] In some embodiments, in the eighth case, the network device determines the first time window in the following manner:

[0191] The network device determines the first time window based on a pre-configured time window;

[0192] or,

[0193] The network device determines the first time window according to the time window indicated by the first timer;

[0194] or,

[0195] The network device determines the first time window based on the pre-configured time window and the time window indicated by the first timer.

[0196] In some embodiments, the network device receives the CSI within a first time window, including:

[0197] If PUCCH resources exist within the first time window, the network device receives the CSI on the PUCCH resources;

[0198] The first time window is determined based on the time window indicated by the first timer; or the first time window is determined based on the DRX activation time.

[0202] In some embodiments, the network device receives the CSI within a first time window, including:

[0203] If PUCCH resources exist within the time window indicated by the first timer, the network device receives the CSI on the PUCCH resources within the pre-configured time window and on the PUCCH resources within the time window indicated by the first timer, respectively.

[0204] or,

[0205] If PUCCH resources exist during the DRX activation period, the network device receives the CSI on PUCCH resources within the pre-configured time window and on PUCCH resources during the DRX activation period, respectively.

[0206] or,

[0207] If PUCCH resources exist within the time window indicated by the first timer, the network device will only receive the CSI on the PUCCH resources within the time window indicated by the first timer;

[0208] or,

[0209] If PUCCH resources exist during the DRX activation period, the network device only receives the CSI on the PUCCH resources during the DRX activation period;

[0214] In some embodiments, the pre-configured time window includes the time window indicated by the DRX duration timer.

[0215] It should be noted that the CSI transmission method on the network device side in this disclosure embodiment is based on the same inventive concept as the CSI transmission method on the terminal side described above. The two embodiments can refer to each other and can achieve the same technical effect. To avoid repetition, they will not be described again here.

[0216] The network device disclosed in this embodiment may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with a wireless terminal via one or more sectors on the air interface, or other names. The network device may be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network equipment involved in this disclosure can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA) system, a NodeB in a wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in this disclosure. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.

[0217] The CSI transmission method of this disclosure will be described below with reference to specific embodiments:

[0218] Example 1: The terminal determines the behavior of reporting periodic CSI based on the first indication information and the configuration of the first high-layer parameters, as shown in Table 1.

[0219] Table 1

[0220] In some embodiments, the pre-configured time window can be determined based on an existing time window, such as the time window indicated by the DRX duration timer; or, the pre-configured time window can be a newly defined time window, such as a new time window different from the time window indicated by the DRX duration timer, or a time window specifically used for the terminal to send CSI when the terminal is listening to LP-WUS, etc., and the embodiments disclosed herein are not limited thereto.

[0221] Example 2: The terminal determines the behavior of reporting periodic CSI based on the configuration of the first instruction information or the first high-layer parameters, as shown in Table 2.

[0222] Table 2

[0223] In some embodiments, the pre-configured time window can be determined based on an existing time window, such as the time window indicated by the DRX duration timer; or, the pre-configured time window can be a newly defined time window, such as a new time window different from the time window indicated by the DRX duration timer, or a time window specifically used for the terminal to send CSI when the terminal is listening to LP-WUS, etc., and the embodiments disclosed herein are not limited thereto.

[0224] Example 3:

[0225] Base station side:

[0226] Step 1: The base station generates an LP-WUS based on the first configuration parameters, which carries first indication information to indicate whether to start a first timer for PDCCH eavesdropping; in some embodiments, the first configuration parameters may include at least one of the following parameters:

[0227] The bit length of the LP-WUS signal;

[0228] Temporal location parameters, such as the correlation parameters between LO and PO, frame-level offset, symbol-level offset, etc.

[0229] Frequency domain location parameters, such as PRB index;

[0230] OOK waveforms, such as OOK-1 and OOK-4M values;

[0231] Signal type, such as sequence-based or encoded-based;

[0232] Encoding methods, such as Manchester coding;

[0233] Step 2: The base station notifies the UE of the first higher-layer parameters configured via higher-layer signaling; in some embodiments, the higher-layer signaling can be common or UE-specific; in some embodiments, the higher-layer parameters can be existing parameters or newly introduced parameters.

[0234] Step 3: The base station periodically transmits LP-WUS; in some embodiments, the period of LP-WUS can be configured independently of C-DRX.

[0235] Terminal side:

[0236] When LP-WUS indicates that the first timer will not wake up, and the first higher-layer parameter is configured, the UE will only report CSI within the pre-configured time window (e.g., the time window indicated by drx-onDurationTimer). When LP-WUS indicates that the first timer will wake up, CSI reporting will occur within both the pre-configured time window (e.g., the time window indicated by drx-onDurationTimer) and the time window indicated by the first timer.

[0237] Step 1: The UE periodically receives and demodulates LP-WUS according to the first configuration parameters.

[0238] Step 2: The UE determines the configuration of the first higher-layer parameter through higher-layer signaling;

[0239] Step 3: The UE determines whether to report CSI based on the first indication information of LP-WUS and the configuration of the first higher-layer parameter. Specifically, when LP-WUS indicates that the first timer will not wake up and there is no configuration of the first higher-layer parameter, the UE does not perform periodic CSI reporting; otherwise, it performs periodic CSI reporting.

[0240] Step 4: The UE determines the first time window for reporting CSI based on the first indication information and the configuration of the first higher layer parameters, as shown in Figure 4.

[0241] 1) If there is a configuration for the first high-level parameter,

[0242] When LP-WUS indicates that the first timer does not wake up (i.e., LP-WUS = 0), the UE reports periodic CSI within a pre-configured time window (such as the time window indicated by drx-onDurationTimer), as shown in scheme 1-1-2 in Figure 4. The circle indicates that periodic CSI is reported within this time window.

[0243] When LP-WUS indicates the first timer wake-up (i.e., LP-WUS=1), the UE reports periodic CSI within the pre-configured time window (such as the time window indicated by drx-onDurationTimer) and the time window indicated by the first timer, as shown in scheme 1-2-3 in Figure 4. The circle indicates that periodic CSI is reported within this time window.

[0244] In some embodiments, if there are no PUCCH resources within the time window indicated by the first timer, periodic CSI reporting is not performed within the time window indicated by the first timer.

[0245] 2) If there is no high-level parameter configuration,

[0246] When LP-WUS indicates the first timer wake-up (i.e., LP-WUS=1), the UE reports periodic CSI within the UE pre-configured time window (such as the time window indicated by drx-onDurationTimer) and the time window indicated by the first timer, as shown in scheme 1-3-3 in Figure 4. The circle indicates that periodic CSI is reported within this time window.

[0247] In some embodiments, if there are no PUCCH resources within the time window indicated by the first timer, periodic CSI reporting is not performed within the time window indicated by the first timer.

[0248] Step 5: The UE performs periodic CSI reporting within the first time window according to the PUCCH configuration resources.

[0249] Example 4:

[0250] Base station side:

[0251] Step 1: The base station generates an LP-WUS based on the first configuration parameters, which carries first indication information to indicate whether to start a first timer for PDCCH eavesdropping; in some embodiments, the first configuration parameters may include at least one of the following parameters:

[0252] The bit length of the LP-WUS signal;

[0253] Temporal location parameters, such as the correlation parameters between LO and PO, frame-level offset, symbol-level offset, etc.

[0254] Frequency domain location parameters, such as PRB index;

[0255] OOK waveforms, such as OOK-1 and OOK-4M values;

[0256] Signal type, such as sequence-based or encoded-based;

[0257] Encoding methods, such as Manchester coding;

[0258] Step 2: The base station notifies the UE of the first higher-layer parameters configured via higher-layer signaling; in some embodiments, the higher-layer signaling can be common or UE-specific; in some embodiments, the higher-layer parameters can be existing parameters or newly introduced parameters.

[0259] Step 3: The base station periodically transmits LP-WUS; in some embodiments, the period of LP-WUS can be configured independently of C-DRX.

[0260] Terminal side:

[0261] When LP-WUS indicates that the first timer will not wake up, and the first higher-layer parameter is configured, the UE reports CSI within the pre-configured time window (e.g., the time window indicated by drx-onDurationTimer) and the time window indicated by the first timer. When LP-WUS indicates that the first timer will wake up, and the first higher-layer parameter is configured, the UE reports CSI within the DRX activation time and the pre-configured time window (e.g., the time window indicated by drx-onDurationTimer); when the first higher-layer parameter is not configured, CSI is reported only within the DRX activation time.

[0262] Step 1: The UE periodically receives and demodulates LP-WUS according to the first configuration parameters.

[0263] Step 2: The UE determines the configuration of the first higher-layer parameter through higher-layer signaling;

[0264] Step 3: The UE determines whether to report CSI based on the first indication information of LP-WUS and the configuration of the first higher-layer parameter. Specifically, when LP-WUS indicates that the first timer will not wake up and there is no configuration of the first higher-layer parameter, the UE does not perform periodic CSI reporting; otherwise, it performs periodic CSI reporting.

[0265] Step 4: The UE determines the first time window for reporting CSI based on the first indication information and the configuration of the first higher layer parameters, as shown in Figure 5.

[0266] 1) If there are high-level parameter configurations,

[0267] When LP-WUS indicates that the first timer will not wake up (i.e., LP-WUS = 0), the UE reports periodic CSI within the pre-configured time window (such as the time window indicated by drx-onDurationTimer) and the time window indicated by the first timer, as shown in scheme 1-1-3 in Figure 5. The circle indicates that periodic CSI is reported within this time window.

[0268] When LP-WUS indicates the first timer wake-up (i.e., LP-WUS=1), the UE reports periodic CSI within the DRX activation time and the pre-configured time window (such as the time window indicated by drx-onDurationTimer), as shown in scheme 1-2-5 in Figure 5. The circle indicates that periodic CSI is reported within this time window.

[0269] In some embodiments, if there are no PUCCH resources during the DRX activation period, CSI is not reported during the DRX activation period.

[0270] 2) If the first high-level parameter is not configured,

[0271] When LP-WUS indicates the first timer wake-up (i.e., LP-WUS=1), the UE only reports CSI during the DRX activation time, as shown in scheme 1-3-4 in Figure 5. The circle indicates that periodic CSI reporting is performed within this time window.

[0272] In some embodiments, if there are no PUCCH resources during the DRX activation period, the UE may behave as follows:

[0273] Behavior 1: The UE does not report CSI;

[0274] Behavior 2: The UE reports CSI within a pre-configured time window (such as the time window indicated by drx-onDurationTimer).

[0275] Step 5: The UE performs periodic CSI reporting within the first time window according to the PUCCH configuration resources.

[0276] Example 5:

[0277] Base station side:

[0278] Step 1: The base station generates an LP-WUS based on the first configuration parameters, which carries first indication information to indicate whether to start a first timer for PDCCH eavesdropping; in some embodiments, the first configuration parameters may include at least one of the following parameters:

[0279] The bit length of the LP-WUS signal;

[0280] Temporal location parameters, such as the correlation parameters between LO and PO, frame-level offset, symbol-level offset, etc.

[0281] Frequency domain location parameters, such as PRB index;

[0282] OOK waveforms, such as OOK-1 and OOK-4M values;

[0283] Signal type, such as sequence-based or encoded-based;

[0284] Encoding methods, such as Manchester coding;

[0285] Step 2: The base station notifies the UE of the first higher-layer parameters configured via higher-layer signaling; in some embodiments, the higher-layer signaling can be common or UE-specific; in some embodiments, the higher-layer parameters can be existing parameters or newly introduced parameters.

[0286] Step 3: The base station periodically transmits LP-WUS; in some embodiments, the period of LP-WUS can be configured independently of C-DRX.

[0287] Terminal side:

[0288] When LP-WUS indicates the first timer wake-up, the UE reports CSI within the pre-configured time window (such as the time window indicated by drx-onDurationTimer) and the DRX activation time.

[0289] Step 1: The UE periodically receives and demodulates LP-WUS according to the first configuration parameters.

[0290] Step 2: The UE determines whether to report based on the first indication information from LP-WUS. Specifically:

[0291] When LP-WUS indicates that the first timer will not wake up (i.e., LP-WUS = 0), the UE will not report periodically CSI, as shown in scheme 1-1-3 in Figure 6.

[0292] When LP-WUS indicates the first timer wake-up (i.e., LP-WUS=1), the UE performs periodic CSI reporting. As shown in scheme 1-2-5 in Figure 6, the UE may perform periodic CSI reporting within a pre-configured time window (such as the time window indicated by drx-onDurationTimer) and during the DRX activation period; or as shown in scheme 1-3-4 in Figure 6, the UE may only perform periodic CSI reporting within a pre-configured time window (such as the time window indicated by drx-onDurationTimer).

[0293] Step 3: The UE reports CSI within the first time window according to pre-agreed rules. The first time window can be one of the following:

[0294] Pre-configured time windows (such as the time window indicated by drx-onDurationTimer);

[0295] The time window indicated by the first timer; for example: when there is PUCCH resource in the time window indicated by the first timer, CSI is reported; otherwise, the UE may not report periodic CSI, or report CSI in a pre-configured time window (such as the time window indicated by drx-onDurationTimer).

[0296] DRX activation time; for example: when there are PUCCH resources during the DRX activation time, CSI is reported; otherwise, the UE may not report periodic CSI, or report CSI within a pre-configured time window (such as the time window indicated by drx-onDurationTimer).

[0297] The pre-configured time window (such as the time window indicated by drx-onDurationTimer) and the time window indicated by the first timer; for example: if there is no PUCCH resource in the time window indicated by the first timer, CSI reporting will only be performed in the pre-configured time window (such as the time window indicated by drx-onDurationTimer);

[0298] Pre-configured time windows (such as the time window indicated by drx-onDurationTimer) and DRX activation time; for example: if there are no PUCCH resources during the DRX activation time, CSI reporting will only be performed within the pre-configured time window (such as the time window indicated by drx-onDurationTimer).

[0299] Step 4: The UE performs periodic CSI reporting within the first time window according to the PUCCH configuration resources.
