[0169] For the relevant embodiments of the terminal and the network device in FIG2 , please refer to the embodiments below, and the present disclosure will not elaborate on them here.
[0170] The embodiments of the present disclosure provide a method for sending information. Figure 3 is a schematic flow chart of a method for sending information according to an embodiment of the present disclosure. The method for sending information shown in this embodiment can be executed by a terminal.
[0171] As shown in FIG3 , the information sending method may include the following steps:
[0172] In step S301, first information is determined according to a power offset parameter;
[0173] In step S302, first information is sent to a network device, where the first information is used to determine channel state information.
[0174] It should be noted that the embodiment shown in FIG. 3 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.
[0175] In some embodiments, the terminal may determine the first information based on a power offset parameter, where the power offset parameter may include but is not limited to a value determined based on a power control offset (powercontrolOffset) in RRC (Radio Resource Control) signaling.
[0176] It should be noted that the power offset parameter is not limited to being determined according to RRC signaling. The terminal can also determine the power offset parameter in other ways, for example, according to the protocol agreement, or according to MAC CE (Media Access Control Control Element, media access control layer control element), or according to DCI (Downlink Control Information, downlink control information).
[0177] In some embodiments, the power offset parameter may represent the difference in EPRE between different downlink information sent by the network device to the terminal. For example, it may represent the difference in EPRE between the PDSCH and CSI-RS. The terminal determines the first information based on the CSI-RS measurement result and the power offset parameter, which can more accurately represent the channel state information. This facilitates more accurate determination of the channel state information by the network device and facilitates subsequent PDSCH scheduling.
[0178] In some embodiments, the power offset parameter can be dynamically adjusted. For example, dynamically adjusting the power offset parameter means that the network device can adjust the power offset parameter based on changes in the service, so that the adjusted power offset parameter accurately represents the difference between the EPRE of the PDSCH and the EPRE of the CSI-RS during communication based on the changed service. For example, the power offset parameter can be adjusted via RRC signaling, DCI, or MAC CE.
[0179] In some embodiments, network devices can dynamically adjust the transmit power of PDSCH and / or CSI-RS based on certain requirements. For example, in a Network Energy Saving (NES) scenario, to reduce the power consumption of network devices, network devices can dynamically adjust the transmit power of PDSCH and / or CSI-RS based on the transmission environment.
[0180] In this case, the first difference value determined by the terminal based on the original power offset parameter (i.e., the power offset parameter before adjustment) is different from the actual second difference value between the CSI-RS EPRE and the PDSCH EPRE. This second difference value is used to accurately determine the channel state information. If the terminal still determines the first information based on the first difference value, the first information will be difficult to use to accurately determine the channel state information, which will cause the network device to fail to accurately determine the channel state information, thereby reducing PDSCH scheduling performance.
[0181] In some embodiments, the network device dynamically adjusts the transmission power of PDSCH and / or CSI-RS, including at least one of the following: dynamically adjusting the frequency domain resources (e.g., bandwidth) used to transmit PDSCH and / or CSI-RS, and dynamically adjusting the power spectral density (PSD) of PDSCH and / or CSI-RS.
[0182] FIG4 is a schematic flow chart of another information transmission method according to an embodiment of the present disclosure. The information transmission method shown in this embodiment can be executed by a terminal. As shown in FIG4, determining the first information based on the power offset parameter includes:
[0183] In step S401, the adjusted power offset parameter is determined according to the instruction information of the network device;
[0184] In step S402, first information is determined according to the adjusted power offset parameter.
[0185] It should be noted that the embodiment shown in FIG. 4 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.
[0186] In some embodiments, due to the dynamic adjustment of the transmit power of the PDSCH and / or CSI-RS by the network device, the first information determined by the terminal based on the first difference determined by the original power offset parameter is difficult to accurately represent the channel state information. In this case, the network device can send indication information to the terminal, wherein the indication information is used to determine the adjusted power offset parameter. The terminal can determine the adjusted power offset parameter based on the indication information, wherein the adjusted power offset parameter can accurately represent the difference between the EPRE of the PDSCH and the EPRE of the CSI-RS, thereby facilitating the first information determined based on the adjusted power offset parameter to accurately determine the channel state information.
[0187] This facilitates the network device to appropriately perform subsequent actions, such as scheduling PDSCH, based on accurate channel state information. For example, if the channel state information is inaccurate and the network device schedules the PDSCH based on the inaccurate channel state information, the selected MCS (Modulation and Coding Scheme) may be less suitable for the channel, which may make it difficult for the terminal to correctly parse the PDSCH. However, according to the embodiments of the present disclosure, when the network device schedules the PDSCH based on accurate channel state information, the selected MCS may be more suitable for the channel, which is conducive to ensuring that the terminal can smoothly parse the PDSCH, thereby ensuring good communication quality.
[0188] In some embodiments, the indication information is used to indicate at least one of the following:
[0189] Adjusted power offset parameter;
[0190] the index of the adjusted power offset parameter;
[0191] an offset of the power offset parameter after adjustment relative to the power offset parameter before adjustment;
[0192] The adjusted power offset parameter is an offset relative to a preset power offset parameter (also referred to as a reference power offset parameter).
[0193] In some embodiments, the indication information may indicate the adjusted power offset parameter, and the terminal may directly determine the adjusted power offset parameter according to the indication information.
[0194] For example, a portion of the indication information may be carried in RRC signaling to indicate a power offset parameter set (e.g., stored in a list), and the terminal may store the power offset parameter set; another portion of the indication information may be carried in downlink control information (DCI) or a media access control layer control element (MAC CE) to indicate a power offset parameter in the power offset parameter set. The terminal may determine, based on the DCI or MAC CE, a power offset parameter in the power offset parameter set as the adjusted power offset parameter.
[0195] For example, the RRC signaling sent by the network device to the terminal includes a CSI-RS resource (CSI-RS resource), such as a non-zero power CSI-RS resource (NZP CSI-RS resource). The information element in the CSI-RS resource may include a power offset parameter list, where the power offset parameter list includes multiple power offset parameters. The network device may send DCI to the terminal, where the DCI is used to indicate a power offset parameter in the power offset parameter list, or to indicate an index of a power offset parameter in the power offset parameter list. After receiving the RRC signaling, the terminal may store the power offset parameter list, and then, after receiving the DCI, may determine the power offset parameter indicated by the DCI in the power offset parameter list as the adjusted power offset parameter.
[0196] In some embodiments, the indication information may indicate the offset of the adjusted power offset parameter relative to the power offset parameter before adjustment, and the terminal may add (or subtract) the offset indicated by the indication information to the power offset parameter before adjustment to obtain the adjusted power offset parameter.
[0197] For example, the power offset parameter before adjustment is PO#1, and the offset is ΔPO. Then the power offset parameter PO#2 after adjustment may be PO#1+ΔPO.
[0198] For example, a portion of the indication information may be carried in RRC signaling to indicate an offset set (e.g., stored in a list), and the terminal may store the offset set; another portion of the indication information may be carried in DCI or MAC CE to indicate an offset or an offset index in the offset set. The terminal may determine, based on the DCI or MAC CE, an offset in the offset set as the offset of the adjusted power offset parameter relative to the pre-adjusted power offset parameter.
[0199] In some embodiments, the indication information may indicate an offset of the adjusted power offset parameter relative to a preset power offset parameter or an index of the offset. The terminal may determine the adjusted power offset parameter based on the offset of the power offset parameter before adjustment relative to the preset power offset parameter and the offset of the adjusted power offset parameter relative to the preset power offset parameter. The preset power offset parameter and the offset of the power offset parameter before adjustment relative to the preset power offset parameter are known to the terminal.
[0200] For example, the power offset parameter before adjustment is PO#1, the offset relative to the preset power offset parameter is ΔPO#1, and the offset of the adjusted power offset parameter PO#2 relative to the preset power offset parameter is ΔPO#2. Then the adjusted power offset parameter PO#2 can be PO#1+ΔPO#2-ΔPO#1.
[0201] For example, a portion of the indication information may be carried in RRC signaling to indicate an offset set (e.g., stored in a list), and the terminal may store the offset set; another portion of the indication information may be carried in DCI or MAC CE to indicate an offset in the offset set. The terminal may determine, based on the DCI or MAC CE, an offset in the offset set as the offset of the adjusted power offset parameter relative to the preset power offset parameter.
[0202] In some embodiments, the indication information is carried in at least one of the following:
[0203] Radio Resource Control (RRC) signaling;
[0204] Downlink Control Information (DCI);
[0205] Medium Access Control Layer Control Element (MAC CE).
[0206] For example, the network device may reconfigure the power offset parameter via RRC signaling;
[0207] For example, the network device can carry indication information through DCI to dynamically indicate the adjusted power offset parameters to the terminal. Compared with carrying indication information through RRC signaling, it is beneficial for the terminal to promptly determine the adjusted power offset parameters, and then promptly determine the first information based on the adjusted power offset parameters and determine the channel state information based on the first information, so that the network device can obtain accurate channel state information in a timely manner, thereby accurately determining the channel state.
[0208] For example, the network device can carry indication information through MAC CE to dynamically indicate the adjusted power offset parameter to the terminal. Compared with carrying indication information through RRC signaling, it is beneficial for the terminal to promptly determine the adjusted power offset parameter, and then promptly determine the first information based on the adjusted power offset parameter and determine the channel state information based on the first information, so that the network device can obtain accurate channel state information in a timely manner, thereby accurately determining the channel state.
[0209] In some embodiments, the downlink control information includes at least one of the following:
[0210] Downlink control information in the UE-specific Search Space (USS);
[0211] Downlink control information in the Common Search Space (CSS).
[0212] For example, the network device may carry indication information in the DCI of the USS and send it to a terminal corresponding to the USS, dynamically indicating the adjusted power offset parameter to the terminal. For example, the network device may carry indication information in the DCI of the CSS and send it to multiple terminals corresponding to the CSS, dynamically indicating the adjusted power offset parameter to the multiple terminals.
[0213] It should be noted that the type of DCI used to carry indication information is not limited to the above-mentioned USS DCI and CSS DCI, but may include any type of DCI. For example, it may include group-common downlink control information (Group-common DCI), cell-specific downlink control information (Cell-specific DCI), terminal-specific downlink control information (UE-specific DCI), etc., which will not be repeated here.
[0214] In some embodiments, the terminal sends the first information based on a reporting configuration of the first information, where the reporting configuration includes multiple sub-configurations, one sub-configuration can be associated with one or more CSI-RS resources, and one CSI-RS resource can correspond to one or more power parameters.
[0215] In some embodiments, a sub-configuration may be associated with a power offset parameter corresponding to a CSI-RS resource, and the association may also be based on associating the power offset parameter with an index in a power offset parameter list. For example, CSI-RS resource #1 corresponds to three power offset parameters, namely PO#1 to PO#3. When sub-configuration #1 is associated with CSI-RS resource #1, sub-configuration #1 may be further associated with PO#1, sub-configuration #1 may be further associated with PO#2, and sub-configuration #1 may be further associated with PO#3.
[0216] In some embodiments, a sub-configuration may be associated with a power offset parameter corresponding to each of a plurality of CSI-RS resources. For example, a sub-configuration may be associated with a power offset parameter having the same index as that corresponding to each of a plurality of CSI-RS resources. For example, CSI-RS resource #1 may correspond to three power offset parameters, PO#1 to PO#3, where PO#1 has an index of 1, PO#2 has an index of 2, and PO#3 has an index of 3. CSI-RS resource #2 may correspond to three power offset parameters, PO#4 to PO#6, where PO#4 has an index of 1, PO#5 has an index of 2, and PO#6 has an index of 3. When sub-configuration #1 is associated with both CSI-RS resource #1 and CSI-RS resource #2, sub-configuration #1 may be further associated with PO#1 and PO#4.
[0217] In some embodiments, a sub-configuration can be associated with multiple power offset parameters corresponding to a CSI-RS resource. For example, CSI-RS resource #1 corresponds to three power offset parameters, PO#1 to PO#3. When sub-configuration #1 is associated with CSI-RS resource #1, it can be further associated with PO#1 and PO#2.
[0218] In some embodiments, a sub-configuration may be associated with multiple power offset parameters corresponding to one or more CSI-RS resources. For example, a sub-configuration may be associated with multiple power offset parameters with the same index corresponding to each CSI-RS resource in multiple CSI-RS resources. For example, CSI-RS resource #1 corresponds to three power offset parameters, namely PO#1 to PO#3. Among the power offset parameters corresponding to CSI-RS resource #1, PO#1 has an index of 1, PO#2 has an index of 2, and PO#3 has an index of 3; CSI-RS resource #2 corresponds to three power offset parameters, namely PO#4 to PO#6. Among the power offset parameters corresponding to CSI-RS resource #2, PO#4 has an index of 1, PO#5 has an index of 2, and PO#6 has an index of 3. When sub-configuration #1 is associated with CSI-RS resource #1 and CSI-RS resource #2, sub-configuration #1 may be further associated with PO#1, PO#2, PO#4, and PO#5.
[0219] For example, the first information may be channel state information. The terminal may determine a reporting resource based on the reporting configuration of the first information, and send the first information to the network device in the reporting resource. The reporting configuration may include multiple sub-configurations, the sub-configuration is associated with a power offset parameter, and may also be associated with a CSI-RS resource for receiving CSI-RS. The terminal may determine multiple reporting resources based on the multiple sub-configurations, and then, after receiving the CSI-RS on the CSI-RS resource associated with the reporting resource, the channel state information may be determined based on the received CSI-RS and the power offset parameter associated with the sub-configuration, and then the determined channel state information may be sent in the reporting resource corresponding to the sub-configuration (e.g., configuration).
[0220] For example, the reporting configuration includes three sub-configurations, namely sub-configuration#1, sub-configuration#2, and sub-configuration#3, among which the power offset parameter associated with sub-configuration#1 is PO#1, the power offset parameter associated with sub-configuration#2 is PO#2, and the power offset parameter associated with sub-configuration#3 is PO#3.
[0221] The terminal determines that the CSI-RS resource associated with sub-configuration #1 is CSI-RS resource #1. When sub-configuration #1 is determined to be activated, after receiving the CSI-RS based on the CSI-RS resource #1 configuration, the terminal can determine the channel state information based on the CSI-RS measurement result and PO #1, and send the determined channel state information using the reporting resource configured in sub-configuration #1.
[0222] The terminal determines that the CSI-RS resource associated with sub-configuration #2 is CSI-RS resource #2. When sub-configuration #2 is determined to be activated, after receiving the CSI-RS based on the CSI-RS resource #2 configuration, the terminal can determine the channel state information based on the CSI-RS measurement result and PO #2, and send the determined channel state information using the reporting resource configured in sub-configuration #2.
[0223] The terminal determines that the CSI-RS resources associated with sub-configuration#3 are CSI-RS resource#1 and CSI-RS resource#3. When it is determined that sub-configuration#3 is activated, after receiving the CSI-RS based on the CSI-RS resource#1 and CSI-RS resource#3 configurations, the terminal can determine the channel state information based on the CSI-RS measurement results and PO#1 and PO#3, and send the determined channel state information in the reporting resources configured in sub-configuration#3.
[0224] For example, the reporting configuration includes at least sub-configuration sub-configuration#1. Sub-configuration#1 is associated with CSI-RS resource#1 and CSI-RS resource#2. CSI-RS resource#1 corresponds to three power offset parameters, namely PO#1 to PO#3; CSI-RS resource#2 corresponds to three power offset parameters, namely PO#4 to PO#6. When sub-configuration#1 is associated with CSI-RS resource#1 and CSI-RS resource#2, sub-configuration#1 can be further associated with PO#1 and PO#4. When the terminal determines that sub-configuration#1 is activated, after receiving the CSI-RS based on the CSI-RS resource#1 configuration and the CSI-RS resource#2 configuration, it can determine the channel state information based on the CSI-RS measurement results and PO#1 and PO#4, and send the determined channel state information in the reporting resources configured by sub-configuration#1.
[0225] FIG5 is a schematic flow chart of another information transmission method according to an embodiment of the present disclosure. The information transmission method shown in this embodiment can be executed by a terminal. As shown in FIG5, determining the adjusted power offset parameter based on the indication information of the network device includes:
[0226] In step S501, an activated sub-configuration is determined in at least one sub-configuration according to indication information of a network device;
[0227] In step S502, it is determined that the power offset parameter associated with the activated sub-configuration is the adjusted power offset parameter.
[0228] It should be noted that the embodiment shown in FIG. 5 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.
[0229] In some embodiments, the network device can activate a sub-configuration in at least one sub-configuration included in the reported configuration through indication information (e.g., DCI). The terminal can determine the activated sub-configuration based on the indication information, and then determine the power offset parameter associated with the activated sub-configuration, and use the determined power offset parameter as the adjusted power offset parameter.
[0230] For example, still taking the above three sub-configurations as an example, the terminal receives CSI-RS on CSI-RS resource #1 associated with sub-configuration #1, can determine the first information based on the CSI-RS measurement result and PO #1, and send the first information (such as channel state information) on the reporting resource configured in sub-configuration #1, where PO #1 is the power offset parameter before adjustment.
[0231] The network device can indicate the activation of sub-configuration#2 through indication information. The terminal determines the activation of sub-configuration#2 based on the indication information, and can determine the power offset parameter PO#2 associated with sub-configuration#2. Then, after the terminal receives CSI-RS on CSI-RS resource#2 associated with sub-configuration#2, it can determine the first information based on the measurement result of CSI-RS and PO#2, where PO#2 is the adjusted power offset parameter, and send the first information (such as channel state information) on the reporting resource configured by sub-configuration#2.
[0232] In some embodiments, after receiving the indication information for activating the sub-configuration, the terminal does not expect to determine the first information based on the CSI-RS before adjusting the transmit power.
[0233] For example, after receiving the indication information for activating the sub-configuration, the terminal can determine that the power offset parameter associated with the sub-configuration is the adjusted power offset parameter, but the terminal needs to determine the first information based on the measurement result of the CSI-RS after adjusting the transmit power and the adjusted power offset parameter.
[0234] When the network device dynamically adjusts the transmit power of PDSCH and / or CSI-RS, it sends an indication message for activating the sub-configuration to the terminal. When the terminal receives the indication message for activating the sub-configuration, the network device has adjusted the transmit power of PDSCH and / or CSI-RS, that is, the power offset parameter, but the CSI-RS after the power offset parameter may have been adjusted has not yet been sent to the terminal. If the terminal still determines and reports the first information based on the measurement result of the CSI-RS with the power offset parameter adjusted and the power offset parameter before the adjustment, the network side cannot determine whether the power offset parameter corresponding to the received first information is before or after the update, and it is difficult to ensure that the first information accurately represents the channel state information.
[0235] Therefore, the terminal may not expect to determine the first information based on the CSI-RS before adjusting the power offset parameter. After receiving the indication information for activating the sub-configuration, the terminal can wait to receive the CSI-RS after adjusting the power offset parameter, and then determine the first information based on the measurement result of the CSI-RS after adjusting the power offset parameter, which is conducive to ensuring that the first information accurately represents the channel state information.
[0236] In some embodiments, the terminal does not expect to send first information determined according to the measurement result of the CSI-RS before adjusting the power offset parameter to the network device after receiving the indication information for activating the sub-configuration.
[0237] For example, after receiving the indication information for activating the sub-configuration, although the terminal can determine that the power offset parameter associated with the sub-configuration is the adjusted power offset parameter, the terminal needs to send the first information determined based on the measurement result of the CSI-RS after the adjusted power offset parameter and the adjusted power offset parameter to the network device.
[0238] When the network device dynamically adjusts the transmit power of PDSCH and / or CSI-RS, it sends an indication message for activating the sub-configuration to the terminal. When the terminal receives the indication message for activating the sub-configuration, the network device has adjusted the transmit power of PDSCH and / or CSI-RS, that is, the power offset parameter, but the CSI-RS after the power offset parameter may have been adjusted has not yet been sent to the terminal. If the terminal still sends the first information determined and reported based on the measurement result of the CSI-RS before the power offset parameter was adjusted and the power offset parameter before the adjustment to the network device, the network side cannot determine whether the power offset parameter corresponding to the received first information is before or after the update, and it is difficult to ensure that the first information accurately represents the channel state information.
[0239] Therefore, the terminal may not expect to send the first information determined based on the measurement result of the CSI-RS before adjusting the power offset parameter to the network device after receiving the indication information for activating the sub-configuration. After receiving the indication information for activating the sub-configuration, the terminal may wait to receive the CSI-RS after the power offset parameter is adjusted, and then send the first information determined based on the measurement result of the CSI-RS after the power offset parameter is adjusted to the network device, which is conducive to ensuring that the first information accurately represents the channel state information.
[0240] In some embodiments, after the network device sends an indication message for activating the sub-configuration to the terminal, if it is determined that the terminal does not expect to determine the first information based on the CSI-RS before adjusting the power offset parameter, the network side can determine that the received channel state information is determined by the terminal based on the measurement results of the CSI-RS after adjusting the power offset parameter and the adjusted power offset parameter, which is beneficial for the network side to schedule subsequent data based on the updated channel state information.
[0241] In some embodiments, after receiving the CSI-RS on the CSI-RS resource corresponding to the sub-configuration activated by the indication information for activating the sub-configuration, the terminal does not expect to send the first information determined based on the power offset parameter before adjustment to the network device. For example, after receiving the indication information for activating the sub-configuration, the terminal can perform channel measurement on the CSI-RS resource associated with the activated sub-configuration, such as receiving the CSI-RS. Then, the first information is determined based on the CSI-RS received on the CSI-RS resource configured for the sub-configuration activated by the indication information and the adjusted power offset parameter, and the above-mentioned first information is sent to the network.
[0242] When dynamically adjusting the transmit power of the PDSCH and / or CSI-RS, i.e., the power offset parameter, the network device may send indication information for activating the sub-configuration to the terminal. When the terminal receives the indication information for activating the sub-configuration, the network device has already adjusted the transmit power of the PDSCH and / or CSI-RS, i.e., the power offset parameter, but the CSI-RS after the power offset parameter may have been adjusted has not yet been sent to the terminal.
[0243] Therefore, the terminal may not send the channel state information to the network device for the time being, but after receiving the CSI-RS on the CSI-RS resource corresponding to the sub-configuration activated by the indication information, calculate and report the first information based on the measurement result of the CSI-RS and the adjusted power offset parameter. Since the CSI-RS sent by the network device on the CSI-RS resource configured by the sub-configuration activated by the indication information is the CSI-RS after the power offset parameter is adjusted, the first information determined by the terminal based on the measurement result of the CSI-RS received on the CSI-RS resource configured by the sub-configuration activated by the indication information and the adjusted power offset parameter can accurately represent the channel state information.
[0244] In some embodiments, the terminal does not expect to send first information determined according to the measurement result of the CSI-RS before adjusting the power offset parameter to the network device after the CSI-RS resource corresponding to the subconfiguration activated by the indication information.
[0245] For example, after receiving indication information for activating a subconfiguration, the terminal may perform CSI measurement, such as receiving CSI-RS, on the CSI-RS resource associated with the activated subconfiguration. The first information is then determined based on the CSI-RS received in the CSI-RS resource configured for the subconfiguration activated by the indication information and the adjusted power offset parameter.
[0246] When dynamically adjusting the transmit power of the PDSCH and / or CSI-RS, i.e., the power offset parameter, the network device may send indication information for activating the sub-configuration to the terminal. When the terminal receives the indication information for activating the sub-configuration, the network device has already adjusted the transmit power of the PDSCH and / or CSI-RS, i.e., the power offset parameter, but the CSI-RS after the power offset parameter may have been adjusted has not yet been sent to the terminal.
[0247] Therefore, after receiving the CSI-RS on the CSI-RS resource corresponding to the sub-configuration activated by the indication information, the terminal can send the first information determined based on the measurement result of the CSI-RS and the adjusted power offset parameter to the network device. Since the CSI-RS sent by the network device on the CSI-RS resource configured by the sub-configuration activated by the indication information is the CSI-RS after the power offset parameter is adjusted, the terminal can obtain the channel state information determined by the measurement result of the CSI-RS received by the CSI-RS resource configured by the sub-configuration activated by the indication information and the adjusted power offset parameter based on the first information sent to the network device. On the other hand, the terminal can continue to report the CSI before the power offset parameter is adjusted after receiving the CSI-RS resource corresponding to the sub-configuration after receiving the indication information. After the base station stores the corresponding CSI information, it can be used for subsequent scheduling with the same power offset parameter.
[0248] FIG6 is a schematic flow chart of another information transmission method according to an embodiment of the present disclosure. The information transmission method shown in this embodiment can be executed by a terminal. As shown in FIG6, determining the first information based on the power offset parameter includes:
[0249] In step S601, a plurality of channel state information is determined according to a plurality of power offset parameters;
[0250] In step S602, first information is determined according to a plurality of channel state information.
[0251] It should be noted that the embodiment shown in FIG. 6 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.
[0252] In some embodiments, the terminal may determine multiple power offset parameters. For example, the multiple power offset parameters include at least one of the following: multiple power offset parameters preconfigured by a network device; and multiple power offset parameters predetermined according to a protocol agreement.
[0253] The terminal may determine the channel state information according to each power offset parameter in the multiple power offset parameters to obtain multiple channel state information, and further determine the first information according to the multiple channel state information.
[0254] For example, the multiple power offset parameters are n power offset parameters, and the terminal can determine the i-th channel state information based on the i-th power offset parameter, where 1≤i≤n, so that n channel state information can be determined based on the n power offset parameters.
[0255] For example, the first information includes multiple pieces of channel state information. Then, the terminal determines the first information according to the multiple pieces of channel state information, and may use the multiple pieces of channel state information as the first information.
[0256] The terminal can send multiple channel state information to the network device, and the network device can store the association between the channel state information and the power offset parameter. The network device dynamically adjusts the transmission power of PDSCH and / or CSI-RS, resulting in adjustment of the power offset parameter. The network device can determine the channel state information corresponding to the adjusted power offset parameter, and then determine the state of the channel based on the channel state information.
[0257] For example, the first information includes first channel state information from multiple channel state information items, and a difference between second channel state information items other than the first channel state information and the first channel state information. The terminal may determine the first information based on the multiple channel state information items by determining the first channel state information from the multiple channel state information items, then determining a difference between each second channel state information item and the first channel state information item, and using the first channel state information item and the at least one difference as the first information.
[0258] The terminal can send the first channel state information and at least one difference to the network device, the network device can restore the at least one difference to at least one channel state information, and the network device can store the association relationship between the channel state information and the power offset parameter. The network device dynamically adjusts the transmission power of PDSCH and / or CSI-RS, resulting in adjustment of the power offset parameter. The network device can determine the channel state information corresponding to the adjusted power offset parameter, and then determine the state of the channel based on the channel state information.
[0259] The following uses several embodiments to exemplify the case where the first information includes multiple channel state information and the case where the first information includes the first channel state information and at least one difference.
[0260] FIG7 is a schematic flow chart of another information sending method according to an embodiment of the present disclosure. The information sending method shown in this embodiment can be executed by a terminal. As shown in FIG7 , sending first information to a network device includes:
[0261] In step S701, a plurality of channel state information are sent to a network device according to a first order.
[0262] It should be noted that the embodiment shown in FIG. 7 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.
[0263] In some embodiments, the first information includes a plurality of channel state information. In this case, when the terminal sends the first information to the network device, the plurality of channel state information may be sent to the network device according to a first order.
[0264] In some embodiments, the first order may be configured by the network device, or may be agreed upon by a protocol, or may be determined by the terminal and indicated to the network device. Regardless of whether the first order is determined by any of the above methods, the network device is known to the network device. Therefore, the network device can determine which channel state information the received multiple pieces of channel state information are based on the first order of the received multiple pieces of channel state information.
[0265] Furthermore, the network device also stores the association between channel state information and power offset parameters. Therefore, the network device can determine the power offset parameter corresponding to each piece of channel state information. Furthermore, when the network device dynamically adjusts the transmit power of the PDSCH and / or CSI-RS, resulting in an adjustment of the power offset parameter, the network device can determine the channel state information corresponding to the adjusted power offset parameter and, based on this channel state information, determine the channel state.
[0266] In some embodiments, the terminal sends multiple channel state information to the network device according to a first order, and can send multiple channel state information in multiple sending processes, for example, one channel state information is sent in each sending process, and the network device can determine the order of the multiple channel state information according to the sequence of the sending processes; or, multiple channel state information can be carried in one uplink information and sent to the network device in one sending process. In this case, the multiple channel state information can be set in multiple positions (for example, multiple bits) in the uplink information according to the first order, and the network device can determine the order of the multiple channel state information according to the position of the channel state information in the uplink information.
[0267] In some embodiments, the first order includes at least one of the following:
[0268] An order of the identifiers of the multiple channel state information, for example, the identifiers of the multiple channel state information are arranged from small to large, or from large to small;
[0269] used to determine the order of magnitudes of multiple power offset parameters of multiple channel state information, such as the order of multiple power offset parameters from small to large, such as the order of multiple power offset parameters from large to small;
[0270] The order of identifiers of multiple sub-configurations in the reporting configuration of the first information.
[0271] For example, the first order includes the identifiers of multiple channel state information in ascending order, and the multiple channel state information is three channel state information. The terminal determines the three channel state information based on the three power offset parameters, and then sends the three channel state information to the network device in ascending order of the channel state information identifiers. For example, if the three channel state information are CSI#1, CSI#2, and CSI#4, then CSI#1, CSI#2, and CSI#4 can be sent to the network device in the order of CSI#1, CSI#2, and CSI#4.
[0272] The first order is known to the network device. Therefore, the network device can determine that the first channel state information sent by the terminal is CSI#1, the second channel state information sent by the terminal is CSI#2, and the third channel state information sent by the terminal is CSI#4 based on the first order.
[0273] Furthermore, the network device also stores an association between channel state information and a power offset parameter. For example, the association is: CSI#1 is associated with power offset parameter PO#1, CSI#2 is associated with power offset parameter PO#2, ..., and CSI#n is associated with power offset parameter PO#n. Furthermore, when the network device dynamically adjusts the transmit power of the PDSCH and / or CSI-RS, resulting in an adjustment of the power offset parameter, the network device can determine the adjusted power offset parameter, for example, the adjusted power offset parameter is PO#2. Based on the aforementioned association, the channel state information can be further determined to be CSI#2, thereby determining the channel state based on CSI#2.
[0274] For example, the first order includes the order of the identifiers of multiple sub-configurations in the reporting configuration of the first information from small to large, and the multiple sub-configurations are 3 sub-configurations, namely sub-configuration#1 identified as 1, sub-configuration#2 identified as 2, and sub-configuration#3 identified as 3.
[0275] Among multiple CSI-RS resources, CSI-RS resource#1 corresponds to 3 power offset parameters, namely PO#1 to PO#3, CSI-RS resource#2 corresponds to 3 power offset parameters, namely PO#4 to PO#6, CSI-RS resource#3 corresponds to 2 power offset parameters, namely PO#7 to PO#8, and CSI-RS resource#4 corresponds to 4 power offset parameters, namely PO#9 to PO#12.
[0276] When sub-configuration #1 is associated with CSI-RS resource #1 and CSI-RS resource #2, it can be further associated with PO #1 and PO #4. When the terminal determines that sub-configuration #1 is activated, after receiving the CSI-RS based on the CSI-RS resource #1 configuration and the CSI-RS resource #2 configuration, it can determine channel state information CSI #1 based on the CSI-RS measurement results and PO #1 and PO #4.
[0277] When sub-configuration #2 is associated with CSI-RS resource #3, it can be further associated with PO #5. When the terminal determines that sub-configuration #2 is activated and receives CSI-RS based on CSI-RS resource #3, it can determine channel state information CSI #2 based on the CSI-RS measurement results and PO #5.
[0278] When sub-configuration #3 is associated with CSI-RS resource #4, it can be further associated with PO #7. When the terminal determines that sub-configuration #3 is activated and receives CSI-RS based on CSI-RS resource #4, it can determine channel state information CSI #3 based on the CSI-RS measurement results and PO #7.
[0279] The order of the three sub-configuration identifiers from small to large is sub-configuration#1, sub-configuration#2, and sub-configuration#3, and the corresponding channel state information order is CSI#1, CSI#2, and CSI#3. When the three sub-configurations are activated, the terminal sends multiple channel state information in the first order. It can first send CSI#1 in the reporting resources configured by sub-configuration#1, then send CSI#2 in the reporting resources configured by sub-configuration#2, and finally send CSI#3 in the reporting resources configured by sub-configuration#3.
[0280] In some embodiments, multiple channel state information can be determined based on dynamic signaling (e.g., at least one of DCI and MAC CE). For example, the terminal can first determine multiple sub-configurations based on the configuration information of the network device (e.g., RRC signaling), and determine the multiple activated sub-configurations based on the indication information of the network device (e.g., at least one of DCI and MAC CE). For any of the multiple sub-configurations, the terminal can receive CSI-RS on the CSI-RS resource associated with the sub-configuration, determine the measurement result of the CSI-RS, and determine the channel state information based on the measurement result and the adjusted power offset parameter. Then, for multiple sub-configurations, multiple channel state information can be determined, and the determined multiple channel state information can be sent to the network device.
[0281] In some embodiments, in addition to determining which channel state information the received multiple channel state information are based on the first order, the network device may achieve this effect in other ways, which is not limited by the present disclosure.
[0282] For example, the network device can configure resources for the terminal to send channel state information. There is an association between the resources and the channel state information. The terminal can send the channel state information on the resources associated with the channel state information. When the network device receives the channel state information, it can determine which channel state information is received based on the resource where the channel state information is located.
[0283] For example, the network device configures resources for the terminal for sending channel state information, and the resources are composed of multiple sub-resources, where the i-th sub-resource is used to send CSI#i. When the terminal sends CSI#1, CSI#2 and CSI#4 to the network device, the first sub-resource can be used to send CSI#1, the second sub-resource can be used to send CSI#2, and the fourth sub-resource can be used to send CSI#4. The network device can determine that the channel state information received in the first sub-resource is CSI#1, the channel state information received in the second sub-resource is CSI#2, and the channel state information received in the fourth sub-resource is CSI#4.
[0284] FIG8 is a schematic flow chart of another information sending method according to an embodiment of the present disclosure. The information sending method shown in this embodiment can be executed by a terminal. As shown in FIG8 , sending first information to a network device includes:
[0285] In step S801, at least one difference value is sent to a network device according to a second order.
[0286] It should be noted that the embodiment shown in FIG8 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.
[0287] In some embodiments, the first information includes first channel state information among the plurality of channel state information, and a difference between second channel state information other than the first channel state information and the first channel state information.
[0288] In some embodiments, the second order may be configured by the network device, or the second order may be agreed upon by a protocol, or the second order may be determined by the terminal and indicated to the network device. Regardless of whether the second order is determined by any of the above methods, the network device is known to the network device. Therefore, based on the second order of the received multiple channel state information, the network device can determine which channel state information each received at least one difference corresponds to, and further restore the corresponding channel state information based on the difference.
[0289] Since the difference in channel state information is generally smaller than the difference in channel state information, sending the difference to the terminal is beneficial to reducing the amount of data required for communication, so as to save communication resources.
[0290] Furthermore, the network device also stores the association between channel state information and power offset parameters. Therefore, the network device can determine the power offset parameter corresponding to each piece of channel state information. Furthermore, when the network device dynamically adjusts the transmit power of the PDSCH and / or CSI-RS, resulting in an adjustment of the power offset parameter, the network device can determine the channel state information corresponding to the adjusted power offset parameter and, based on this channel state information, determine the channel state.
[0291] In some embodiments, the terminal sends the first channel state signal and at least one difference value to the network device according to the second order. The first channel state signal and at least one difference value may be sent in multiple sending processes, for example, one difference value is sent in each sending process, and the network device can determine the order of the first channel state signal and the at least one difference value according to the sequence of the sending processes; or, the first channel state signal and at least one difference value may be carried in an uplink message in one sending process and sent to the network device. In this case, the first channel state signal and the at least one difference value may be set in multiple positions (for example, multiple bits) in the uplink information according to the first order, and the network device can determine the order of the first channel state signal and the at least one difference value according to the position of the channel state information in the uplink information.
[0292] In some embodiments, the first channel state information includes at least one of the following:
[0293] The channel state information having the largest corresponding value among multiple channel state information;
[0294] Channel state information determined according to a maximum power offset parameter among multiple power offset parameters;
[0295] Channel state information determined according to a minimum power offset parameter among multiple power offset parameters.
[0296] In some embodiments, the second sequence includes at least one of the following:
[0297] An order of identifiers of the second channel state information, for example, an order of identifiers of the second channel state information from small to large, for example, an order of identifiers of the second channel state information from large to small;
[0298] An order for determining the magnitude of the power offset parameter of the second channel state information, for example, an order for determining the power offset parameter of the second channel state information from small to large, for example, an order for determining the power offset parameter of the second channel state information from large to small;
[0299] The order of identifiers of multiple sub-configurations in the reporting configuration of the first information.
[0300] In some embodiments, the channel state information may include at least one of the following: RI (Rank Indication), PTI (Precoding Type Indicator), PMI (Precoding Matrix Indicator) and CQI (Channel Quality Indicator).
[0301] Taking the PMI in the channel state information as an example, the first channel state information includes the channel state information with the largest corresponding value among multiple channel state information. The PMI may be a value used to determine a PM (Precoding Matrix).
[0302] For example, each channel state information includes a PMI, so the multiple channel state information may include multiple PMIs. The first channel state information may be the PMI with the largest corresponding value among the multiple PMIs, and the second channel state information may be the PMI other than PMI#0 among the multiple PMIs.
[0303] For example, the multiple PMIs are 3 PMIs, namely PMI#1, PMI#2 and PMI#4, where the PMI with the largest corresponding value is PMI#2. Then the first channel state information is PMI#2, and the second channel state information includes PMI#1 and PMI#4.
[0304] The terminal may determine a difference D#12 between PMI#1 and PMI#2, and a difference D#42 between PMI#4 and PMI#2, wherein the first information includes PMI#2, D#12, and D#42. The terminal may send PMI#2, D#12, and D#42 to the network device in the second order.
[0305] For example, when the first channel state information includes channel state information having a maximum corresponding value among multiple channel state information, the terminal may further send a power offset parameter or a power offset parameter index corresponding to the channel state information having the maximum corresponding value to the network device. The terminal may determine the power offset parameter or the power offset parameter index corresponding to the channel state information having the maximum corresponding value based on a preset association relationship.
[0306] For example, the preset association relationship may include channel state information corresponding to power offset parameter values from small to large (or from large to small). Taking small to large as an example, the i-th power offset parameter corresponds to the i-th smallest power offset parameter. For example, taking four power offset parameters as an example, from small to large, they are PO#1, PO#2, PO#3, and PO#4. Then, the first power offset parameter is PO#1, the second power offset parameter is PO#2, the third power offset parameter is PO#3, and the fourth power offset parameter is PO#4. Based on the preset association relationship, the network device can determine that the four received power offset parameters are PO#1, PO#2, PO#3, and PO#4, respectively.
[0307] For example, the preset relationship may be power offset parameters corresponding to channel state information from small to large (or from large to small). Taking small to large as an example, the i-th power offset parameter corresponds to the power offset parameter corresponding to the i-th smallest channel state information. For example, taking the channel state information corresponding to four power offset parameters as an example, from small to large, they are CSI#3, CSI#4, CSI#1, and CSI#2. The power offset parameters corresponding to these four channel state information are PO#3, PO#4, PO#1, and PO#2, respectively. Then, the first power offset parameter is PO#3, the second power offset parameter is PO#4, the third power offset parameter is PO#1, and the fourth power offset parameter is PO#2. Based on the preset association relationship, the network device can determine that the four received power offset parameters are PO#3, PO#4, PO#1, and PO#2, respectively.
[0308] For example, the first channel state information may be located at a preset position in the second sequence, such as at a starting position or at an ending position, with the first channel state information being located at the starting position as an example. The second sequence includes the identifiers of the second channel state information arranged in ascending order, where the identifier of the second channel state information corresponding to D#12 is 2 and the identifier of the second channel state information corresponding to D#42 is 4. Then, in the second sequence, D#12 is arranged before D#42, and the terminal may send PMI#2, D#12, and D#42 to the network device in the order of PMI#2, D#12, and D#42.
[0309] The second order is known to the network device. Therefore, based on the second order, the network device can determine that the first PMI sent by the terminal is PMI#2, the second difference sent by the terminal is D#12, and the third difference sent by the terminal is D#42. The network device can then restore the difference to the corresponding channel state information. For example, the network device can add the difference to the first channel state information to obtain the channel state information corresponding to the difference. For example, for D#12, PMI#2 and D#12 can be added to obtain PMI#1. For D#42, PMI#2 and D#42 can be added to obtain PMI#4.
[0310] Furthermore, the network device also stores an association between channel state information and a power offset parameter. For example, the association is: PMI#1 is associated with power offset parameter PO#1, PMI#2 is associated with power offset parameter PO#2, ..., and PMI#n is associated with power offset parameter PO#n. Furthermore, when the network device dynamically adjusts the transmit power of the PDSCH and / or CSI-RS, resulting in an adjustment of the power offset parameter, the network device can determine the adjusted power offset parameter, for example, the adjusted power offset parameter is PO#2. Based on the aforementioned association, the channel state information can be further determined to be PMI#2, thereby determining the channel state based on PMI#2 (and also considering other information in the channel state information where PMI#2 is located).
[0311] In some embodiments, when the terminal sends the first channel state information to the network device, it may also send a power offset parameter used to determine the first channel state information to the network device so that the network device can accurately determine the power offset parameter associated with the first channel state information.
[0312] In some embodiments, in addition to determining which channel state information the at least one received difference corresponds to according to the second order, the network device may also achieve this effect in other ways, which is not limited by the present disclosure.
[0313] For example, the network device can configure multiple resources for sending channel state information for the terminal. There is an association between the resources and the channel state information. The terminal can send the first channel state information and at least one difference value in the resources associated with the channel state information. When the network device receives the channel state information, it can determine which channel state information the received difference corresponds to based on the resource where the channel state information is located.
[0314] For example, the network device configures resources for the terminal for sending channel state information, and the resources are composed of multiple sub-resources, where the i-th sub-resource is used to send CSI#i. When the terminal sends PMI#1, PMI#2 and PMI#4 to the network device, the first sub-resource can be used to send PMI#2, the second sub-resource can be used to send D#12, and the fourth sub-resource can be used to send D#42. The network device can determine that the channel state information received in the first sub-resource is PMI#2, the channel state information received in the second sub-resource is D#12, and the channel state information received in the fourth sub-resource is D#42.

[0321] The embodiments of the present disclosure provide a method for receiving information. Figure 9 is a schematic flow chart of a method for receiving information according to an embodiment of the present disclosure. The information receiving method shown in this embodiment can be executed by a network device, and the access network device can communicate with the terminal.
[0322] As shown in FIG9 , the information receiving method may include the following steps:
[0323] In step S901, a power offset parameter is sent to the terminal;
[0324] In step S902, the receiving terminal determines first information according to the power offset parameter, where the first information is used to determine channel state information.
[0325] It should be noted that the embodiment shown in FIG. 9 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.
[0326] In some embodiments, the network device may send a power offset parameter to the terminal, and the terminal may determine the first information based on the power offset parameter. The network device sending the power offset parameter to the terminal may include sending a power control offset (powercontrolOffset) in RRC signaling to the terminal, and the terminal may determine the power offset parameter based on the power control offset in the RRC signaling.
[0327] It should be noted that the power offset parameter is not limited to being indicated through RRC signaling. The network device can also indicate the power offset parameter to the terminal in other ways, for example, it can indicate the power offset parameter through MAC CE or through DCI.
[0328] In some embodiments, the power offset parameter may represent the difference in EPRE between different downlink information sent by the network device to the terminal. For example, it may represent the difference in EPRE of the PDSCH and the EPRE of the CSI-RS. The terminal determines the first information based on the CSI-RS measurement result and the power offset parameter, which can more accurately represent the channel state information. Thus, the network device can more accurately determine the channel state information based on the first information, which is beneficial for subsequent PDSCH scheduling.
[0329] In some embodiments, the power offset parameter can be dynamically adjusted. For example, the network device's dynamic adjustment of the power offset parameter means that the network device can adjust the power offset parameter based on changes in the service, so that the adjusted power offset parameter accurately represents the difference between the EPRE of the PDSCH and the EPRE of the CSI-RS during communication based on the changed service. For example, the power offset parameter can be adjusted via RRC signaling, DCI, or MAC CE.
[0330] In some embodiments, network devices can dynamically adjust the transmit power of PDSCH and / or CSI-RS based on certain requirements. For example, in a Network Energy Saving (NES) scenario, to reduce the power consumption of network devices, network devices can dynamically adjust the transmit power of PDSCH and / or CSI-RS based on the transmission environment.
[0331] In this case, the first difference value determined by the terminal based on the original power offset parameter (i.e., the power offset parameter before adjustment) is different from the actual second difference value between the CSI-RS EPRE and the PDSCH EPRE. This second difference value is used to accurately determine the channel state information. If the terminal still determines the first information based on the first difference value, the first information will be difficult to use to accurately determine the channel state information, which will cause the network device to fail to accurately determine the channel state information, thereby reducing PDSCH scheduling performance.
[0332] In some embodiments, the network device dynamically adjusts the transmission power of PDSCH and / or CSI-RS, including at least one of the following: dynamically adjusting the frequency domain resources (e.g., bandwidth) used to transmit PDSCH and / or CSI-RS, and dynamically adjusting the power spectrum density (PSD) of PDSCH and / or CSI-RS.
[0333] FIG10 is a schematic flow chart of another information receiving method according to an embodiment of the present disclosure. The information sending method shown in this embodiment can be executed by a network device. As shown in FIG10 , the information receiving method further includes:
[0334] In step S1001, indication information is sent to the terminal, where the indication information is used to determine an adjusted power offset parameter.
[0335] It should be noted that the embodiment shown in FIG. 10 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed, and the present disclosure does not limit it.
[0336] In some embodiments, due to the dynamic adjustment of the transmit power of the PDSCH and / or CSI-RS by the network device, the first information determined by the terminal based on the first difference determined by the original power offset parameter is difficult to accurately represent the channel state information. In this case, the network device can send indication information to the terminal, wherein the indication information is used to determine the adjusted power offset parameter. The terminal can determine the adjusted power offset parameter based on the indication information, wherein the adjusted power offset parameter can accurately represent the difference between the EPRE of the PDSCH and the EPRE of the CSI-RS, thereby facilitating the first information determined based on the adjusted power offset parameter to accurately determine the channel state information.
[0337] In some embodiments, receiving the first information determined by the terminal according to the power offset parameter includes: the receiving terminal determining the first information according to the adjusted power offset parameter.
[0338] Since the first information determined by the terminal according to the power offset parameter is more accurate, the network device can receive the first information determined by the terminal according to the adjusted power offset parameter, thereby facilitating the network device to appropriately perform subsequent actions according to accurate channel state information, such as scheduling PDSCH. For example, when the channel state information is inaccurate and the network device schedules PDSCH according to the inaccurate channel state information, the selected MCS has poor applicability to the channel, which may make it difficult for the terminal to correctly parse the PDSCH. According to an embodiment of the present disclosure, when the network device can schedule PDSCH according to accurate channel state information, the selected MCS has better applicability to the channel, which is conducive to ensuring that the terminal can smoothly parse the PDSCH, so as to ensure good communication quality.
[0339] In some embodiments, the indication information is used to indicate at least one of the following:
[0340] Adjusted power offset parameter;
[0341] the index of the adjusted power offset parameter;
[0342] an offset of the power offset parameter after adjustment relative to the power offset parameter before adjustment;
[0343] The offset of the adjusted power offset parameter relative to the preset power offset parameter.
[0344] In some embodiments, the indication information may indicate the adjusted power offset parameter, and the terminal may directly determine the adjusted power offset parameter according to the indication information.
[0345] For example, a portion of the indication information may be carried in RRC signaling to indicate a power offset parameter set (e.g., stored in a list), and the terminal may store the power offset parameter set. Another portion of the indication information may be carried in downlink control information (DCI) or a media access control layer control element (MAC CE) to indicate an index of a power offset parameter or offset in the power offset parameter set. The terminal may determine, based on the DCI or MAC CE, a power offset parameter in the power offset parameter set as the adjusted power offset parameter.
[0346] For example, the RRC signaling sent by the network device to the terminal includes a CSI-RS resource, such as a non-zero power CSI-RS resource (NZP CSI-RS resource). The information element in the CSI-RS resource may include a power offset parameter list, where the power offset parameter list includes multiple power offset parameters or indexes of multiple offsets. The network device may send DCI to the terminal, where the DCI is used to indicate a power offset parameter in the power offset parameter list, or to indicate an index of a power offset parameter in the power offset parameter list. After receiving the RRC signaling, the terminal may store the power offset parameter list, and then, after receiving the DCI, may determine the power offset parameter indicated by the DCI in the power offset parameter list as the adjusted power offset parameter.
[0347] In some embodiments, the indication information may indicate the offset of the adjusted power offset parameter relative to the power offset parameter before adjustment, and the terminal may add (or subtract) the offset indicated by the indication information to the power offset parameter before adjustment to obtain the adjusted power offset parameter.
[0348] For example, the power offset parameter before adjustment is PO#1, and the offset is ΔPO. Then the power offset parameter PO#2 after adjustment may be PO#1+ΔPO.
[0349] For example, a portion of the indication information may be carried in RRC signaling to indicate an offset set (e.g., stored in a list), and the terminal may store the offset set; another portion of the indication information may be carried in DCI or MAC CE to indicate an offset in the offset set. The terminal may determine, based on the DCI or MAC CE, an offset in the offset set as the offset of the adjusted power offset parameter relative to the pre-adjusted power offset parameter.
[0350] In some embodiments, the indication information may indicate an offset of the adjusted power offset parameter relative to a preset power offset parameter, and the terminal may determine the adjusted power offset parameter based on the offset of the power offset parameter before adjustment relative to the preset power offset parameter and the offset of the adjusted power offset parameter relative to the preset power offset parameter. The preset power offset parameter and the offset of the power offset parameter before adjustment relative to the preset power offset parameter are known to the terminal.
[0351] For example, the power offset parameter before adjustment is PO#1, the offset relative to the preset power offset parameter is ΔPO#1, and the offset of the adjusted power offset parameter PO#2 relative to the preset power offset parameter is ΔPO#2. Then the adjusted power offset parameter PO#2 can be PO#1+ΔPO#2-ΔPO#1.
[0352] For example, a portion of the indication information may be carried in RRC signaling to indicate an offset set (e.g., stored in a list), and the terminal may store the offset set; another portion of the indication information may be carried in DCI or MAC CE to indicate an offset in the offset set. The terminal may determine, based on the DCI or MAC CE, an offset in the offset set as the offset of the adjusted power offset parameter relative to the preset power offset parameter.
[0353] In some embodiments, the indication information is carried in at least one of the following:
[0354] Radio Resource Control (RRC) signaling;
[0355] Downlink control information (DCI);
[0356] Medium Access Control Layer Control Element (MAC CE).
[0357] For example, the network device may reconfigure the power offset parameter via RRC signaling;
[0358] For example, the network device can carry indication information through DCI to dynamically indicate the adjusted power offset parameters to the terminal. Compared with carrying indication information through RRC signaling, it is beneficial for the terminal to promptly determine the adjusted power offset parameters, and then promptly determine the first information based on the adjusted power offset parameters and determine the channel state information based on the first information, so that the network device can obtain accurate channel state information in a timely manner, thereby accurately determining the channel state.
[0359] For example, the network device can carry indication information through MAC CE to dynamically indicate the adjusted power offset parameter to the terminal. Compared with carrying indication information through RRC signaling, it is beneficial for the terminal to promptly determine the adjusted power offset parameter, and then promptly determine the first information based on the adjusted power offset parameter and determine the channel state information based on the first information, so that the network device can obtain accurate channel state information in a timely manner, thereby accurately determining the channel state.
[0360] In some embodiments, the downlink control information includes at least one of the following:
[0361] Downlink control information in the terminal-specific search space (USS);
[0362] Downlink control information in the common search space (CSS).
[0363] For example, the network device may carry indication information in the DCI of the USS and send it to a terminal corresponding to the USS, dynamically indicating the adjusted power offset parameter to the terminal. For example, the network device may carry indication information in the DCI of the CSS and send it to multiple terminals corresponding to the CSS, dynamically indicating the adjusted power offset parameter to the multiple terminals.
[0364] It should be noted that the type of DCI used to carry indication information is not limited to the above-mentioned USS DCI and CSS DCI, but may include any type of DCI. For example, it may include group-common downlink control information (Group-common DCI), cell-specific downlink control information (Cell-specific DCI), terminal-specific downlink control information (UE-specific DCI), etc., which will not be repeated here.
[0365] In some embodiments, the information receiving method further includes: sending a reporting configuration of the first information to the terminal, wherein the reporting configuration includes multiple sub-configurations, and the sub-configurations are associated with the power offset parameter.
[0366] After the terminal receives the reporting configuration of the first information, it can send the first information based on the reporting configuration of the first information. The reporting configuration includes multiple sub-configurations. One sub-configuration can be associated with one or more CSI-RS resources, and one CSI-RS resource can correspond to one or more power parameters.
[0367] In some embodiments, a sub-configuration may be associated with a power offset parameter corresponding to a CSI-RS resource, and the association may also be based on associating the power offset parameter with an index in a power offset parameter list. For example, CSI-RS resource #1 corresponds to three power offset parameters, namely PO#1 to PO#3. When sub-configuration #1 is associated with CSI-RS resource #1, sub-configuration #1 may be further associated with PO#1, sub-configuration #1 may be further associated with PO#2, and sub-configuration #1 may be further associated with PO#3.
[0368] In some embodiments, a sub-configuration may be associated with a power offset parameter corresponding to each of a plurality of CSI-RS resources. For example, a sub-configuration may be associated with a power offset parameter having the same index as that corresponding to each of a plurality of CSI-RS resources. For example, CSI-RS resource #1 may correspond to three power offset parameters, PO#1 to PO#3, where PO#1 has an index of 1, PO#2 has an index of 2, and PO#3 has an index of 3; and CSI-RS resource #2 may correspond to three power offset parameters, PO#4 to PO#6, where PO#4 has an index of 1, PO#5 has an index of 2, and PO#6 has an index of 3. When sub-configuration #1 is associated with both CSI-RS resource #1 and CSI-RS resource #2, sub-configuration #1 may be further associated with PO#1 and PO#4.
[0369] In some embodiments, a sub-configuration can be associated with multiple power offset parameters corresponding to a CSI-RS resource. For example, CSI-RS resource #1 corresponds to three power offset parameters, PO#1 to PO#3. When sub-configuration #1 is associated with CSI-RS resource #1, it can be further associated with PO#1 and PO#2.
[0370] In some embodiments, a sub-configuration may be associated with multiple power offset parameters corresponding to one or more CSI-RS resources. For example, a sub-configuration may be associated with multiple power offset parameters with the same index corresponding to each CSI-RS resource in multiple CSI-RS resources. For example, CSI-RS resource #1 corresponds to three power offset parameters, namely PO#1 to PO#3. Among the power offset parameters corresponding to CSI-RS resource #1, PO#1 has an index of 1, PO#2 has an index of 2, and PO#3 has an index of 3; CSI-RS resource #2 corresponds to three power offset parameters, namely PO#4 to PO#6. Among the power offset parameters corresponding to CSI-RS resource #2, PO#4 has an index of 1, PO#5 has an index of 2, and PO#6 has an index of 3. When sub-configuration #1 is associated with CSI-RS resource #1 and CSI-RS resource #2, sub-configuration #1 may be further associated with PO#1, PO#2, PO#4, and PO#5.
[0371] For example, the first information may be channel state information. The terminal may determine a reporting resource based on the reporting configuration of the first information, and send the first information to the network device in the reporting resource. The reporting configuration may include multiple sub-configurations, the sub-configuration is associated with a power offset parameter, and may also be associated with a CSI-RS resource for receiving CSI-RS. The terminal may determine multiple reporting resources based on the multiple sub-configurations, and then, after receiving the CSI-RS on the CSI-RS resource associated with the reporting resource, the channel state information may be determined based on the received CSI-RS and the power offset parameter associated with the sub-configuration, and then the determined channel state information may be sent in the reporting resource corresponding to the sub-configuration (e.g., configuration).
[0372] For example, the reporting configuration includes three sub-configurations, namely sub-configuration#1, sub-configuration#2, and sub-configuration#3, among which the power offset parameter associated with sub-configuration#1 is PO#1, the power offset parameter associated with sub-configuration#2 is PO#2, and the power offset parameter associated with sub-configuration#3 is PO#3.
[0373] The terminal determines that the CSI-RS resource associated with sub-configuration #1 is CSI-RS resource #1. When sub-configuration #1 is determined to be activated, after receiving the CSI-RS based on the CSI-RS resource #1 configuration, the terminal can determine the channel state information based on the CSI-RS measurement result and PO #1, and send the determined channel state information using the reporting resource configured in sub-configuration #1.
[0374] The terminal determines that the CSI-RS resource associated with sub-configuration #2 is CSI-RS resource #2. When sub-configuration #2 is determined to be activated, after receiving the CSI-RS based on the CSI-RS resource #2 configuration, the terminal can determine the channel state information based on the CSI-RS measurement result and PO #2, and send the determined channel state information using the reporting resource configured in sub-configuration #2.
[0375] The terminal determines that the CSI-RS resources associated with sub-configuration#3 are CSI-RS resource#1 and CSI-RS resource#3. When it is determined that sub-configuration#3 is activated, after receiving the CSI-RS based on the CSI-RS resource#1 and CSI-RS resource#3 configurations, the terminal can determine the channel state information based on the CSI-RS measurement results and PO#1 and PO#3, and send the determined channel state information in the reporting resources configured in sub-configuration#3.
[0376] For example, the reporting configuration includes at least sub-configuration sub-configuration#1. Sub-configuration#1 is associated with CSI-RS resource#1 and CSI-RS resource#2. CSI-RS resource#1 corresponds to three power offset parameters, namely PO#1 to PO#3; CSI-RS resource#2 corresponds to three power offset parameters, namely PO#4 to PO#6. When sub-configuration#1 is associated with CSI-RS resource#1 and CSI-RS resource#2, sub-configuration#1 can be further associated with PO#1 and PO#4. When the terminal determines that sub-configuration#1 is activated, after receiving the CSI-RS based on the CSI-RS resource#1 configuration and the CSI-RS resource#2 configuration, it can determine the channel state information based on the CSI-RS measurement results and PO#1 and PO#4, and send the determined channel state information in the reporting resources configured by sub-configuration#1.
[0377] In some embodiments, the network device can activate a sub-configuration in at least one sub-configuration included in the reported configuration through indication information (e.g., DCI). The terminal can determine the activated sub-configuration based on the indication information, and then determine the power offset parameter associated with the activated sub-configuration, and use the determined power offset parameter as the adjusted power offset parameter.
[0378] For example, still taking the above three sub-configurations as an example, the terminal receives CSI-RS on CSI-RS resource #1 associated with sub-configuration #1, can determine the first information based on the CSI-RS measurement result and PO #1, and send the first information (such as channel state information) on the reporting resource configured in sub-configuration #1, where PO #1 is the power offset parameter before adjustment.
[0379] The network device can indicate the activation of sub-configuration#2 through indication information. The terminal determines the activation of sub-configuration#2 based on the indication information, and can determine the power offset parameter PO#2 associated with sub-configuration#2. Then, after the terminal receives CSI-RS on CSI-RS resource#2 associated with sub-configuration#2, it can determine the first information based on the measurement result of CSI-RS and PO#2, where PO#2 is the adjusted power offset parameter, and send the first information (such as channel state information) on the reporting resource configured by sub-configuration#2.
[0380] In some embodiments, after sending indication information for activating the sub-configuration to the terminal, the network device can determine that the received channel state information is determined by the terminal based on the measurement result of the CSI-RS after adjusting the transmit power and the adjusted power offset parameter.
[0381] In some embodiments, after receiving the indication information for activating the sub-configuration, the terminal does not expect to determine the first information based on the CSI-RS before adjusting the transmit power.
[0382] In some embodiments, after receiving the CSI-RS on the CSI-RS resource corresponding to the sub-configuration activated by the indication information for activating the sub-configuration, the terminal does not expect to send the first information determined according to the power offset parameter before adjustment to the network device. For example, after receiving the indication information for activating the sub-configuration, the terminal can perform CSI measurement on the CSI-RS resource associated with the activated sub-configuration, such as receiving the CSI-RS. The first information is then determined based on the CSI-RS received on the CSI-RS resource configured for the sub-configuration activated by the indication information and the adjusted power offset parameter.
[0383] When dynamically adjusting the transmit power of the PDSCH and / or CSI-RS, i.e., the power offset parameter, the network device may send indication information for activating the sub-configuration to the terminal. When the terminal receives the indication information for activating the sub-configuration, the network device has already adjusted the transmit power of the PDSCH and / or CSI-RS, i.e., the power offset parameter, but the CSI-RS after the power offset parameter may have been adjusted has not yet been sent to the terminal.
[0384] Therefore, after receiving the CSI-RS on the CSI-RS resource corresponding to the sub-configuration activated by the indication information, the terminal can send the first information determined according to the measurement result of the CSI-RS and the adjusted power offset parameter to the network device. Since the CSI-RS sent by the network device on the CSI-RS resource configured by the sub-configuration activated by the indication information is the CSI-RS after the power offset parameter is adjusted, the terminal can determine the channel state information of the measurement result of the CSI-RS received by the CSI-RS resource configured by the sub-configuration activated by the indication information and the adjusted power offset parameter based on the first information sent to the network device. On the other hand, the terminal can continue to report the CSI before the power offset parameter is adjusted after receiving the CSI-RS resource corresponding to the sub-configuration after receiving the indication information. After the base station stores the corresponding CSI information, it can be used for subsequent scheduling of the same power offset parameter.
[0385] In some embodiments, the information receiving method further includes: determining a plurality of channel state information according to the first information.
[0386] For example, the terminal may determine multiple power offset parameters. For example, the multiple power offset parameters include at least one of the following: multiple power offset parameters pre-configured by the network device; and multiple power offset parameters predetermined according to a protocol agreement.
[0387] The terminal may determine the channel state information according to each power offset parameter in the multiple power offset parameters to obtain multiple channel state information, and further determine the first information according to the multiple channel state information.
[0388] For example, the multiple power offset parameters are n power offset parameters, and the terminal can determine the i-th channel state information based on the i-th power offset parameter, where 1≤i≤n, so that n channel state information can be determined based on the n power offset parameters.
[0389] For example, the first information includes multiple pieces of channel state information. The terminal may determine the first information based on the multiple pieces of channel state information by using the multiple pieces of channel state information as the first information. The network device may determine the multiple pieces of channel state information based on the first information by acquiring the multiple pieces of channel state information included in the first information.
[0390] The network device can store the association between channel state information and power offset parameters. The network device dynamically adjusts the transmission power of PDSCH and / or CSI-RS, resulting in adjustment of the power offset parameters. The network device can determine the channel state information corresponding to the adjusted power offset parameters, and then determine the state of the channel based on the channel state information.
[0391] For example, the first information includes first channel state information among multiple channel state information, and a difference between second channel state information other than the first channel state information and the first channel state information. The network device determines the multiple channel state information based on the first information by first determining the first channel state information among the multiple channel state information, then determining the difference between each second channel state information and the first channel state information, and recovering the multiple second channel state information based on the first channel state information and the at least one difference. The determined multiple channel state information includes the first channel state information and the multiple second channel state information.
[0392] The network device can restore at least one difference into at least one channel state information, and the network device can store the association relationship between the channel state information and the power offset parameter. The network device dynamically adjusts the transmission power of PDSCH and / or CSI-RS, resulting in adjustment of the power offset parameter. The network device can determine the channel state information corresponding to the adjusted power offset parameter, and then determine the state of the channel based on the channel state information.
[0393] In some embodiments, the first information includes a plurality of channel state information.
[0394] In some embodiments, receiving first information determined by the terminal according to the power offset parameter includes: receiving a plurality of channel state information sent by the terminal according to a first order.
[0395] In some embodiments, the first information includes multiple pieces of channel state information. In this case, when the terminal sends the first information to the network device, the multiple pieces of channel state information may be sent to the network device according to a first order. Correspondingly, the network device may receive the multiple pieces of channel state information sent by the terminal according to the first order.
[0396] In some embodiments, the first order may be configured by the network device, or may be agreed upon by a protocol, or may be determined by the terminal and indicated to the network device. Regardless of whether the first order is determined by any of the above methods, the network device is known to the network device. Therefore, the network device can determine which channel state information the received multiple pieces of channel state information are based on the first order of the received multiple pieces of channel state information.
[0397] Furthermore, the network device also stores the association between channel state information and power offset parameters. Therefore, the network device can determine the power offset parameter corresponding to each piece of channel state information. Furthermore, when the network device dynamically adjusts the transmit power of the PDSCH and / or CSI-RS, resulting in an adjustment of the power offset parameter, the network device can determine the channel state information corresponding to the adjusted power offset parameter and, based on this channel state information, determine the channel state.
[0398] In some embodiments, the terminal sends multiple channel state information to the network device according to a first order, and can send multiple channel state information in multiple sending processes, for example, one channel state information is sent in each sending process, and the network device can determine the order of the multiple channel state information according to the sequence of the sending processes; or, multiple channel state information can be carried in one uplink information and sent to the network device in one sending process. In this case, the multiple channel state information can be set in multiple positions (for example, multiple bits) in the uplink information according to the first order, and the network device can determine the order of the multiple channel state information according to the position of the channel state information in the uplink information.
[0399] In some embodiments, the first order includes at least one of the following:
[0400] An order of the identifiers of the multiple channel state information, for example, the identifiers of the multiple channel state information are arranged from small to large, or from large to small;
[0401] used to determine the order of magnitudes of multiple power offset parameters of multiple channel state information, such as the order of multiple power offset parameters from small to large, such as the order of multiple power offset parameters from large to small;
[0402] The order of the identifiers of the multiple sub-configurations in the reporting configuration of the first information, for example, the identifiers of the multiple sub-configurations are from small to large, for example, the identifiers of the multiple sub-configurations are from large to small.
[0403] For example, the first order includes the identifiers of multiple channel state information in ascending order, and the multiple channel state information is three channel state information. The terminal determines the three channel state information based on the three power offset parameters, and then sends the three channel state information to the network device in ascending order of the channel state information identifiers. For example, if the three channel state information are CSI#1, CSI#2, and CSI#4, then CSI#1, CSI#2, and CSI#4 can be sent to the network device in the order of CSI#1, CSI#2, and CSI#4.
[0404] The first order is known to the network device. Therefore, the network device can determine that the first channel state information sent by the terminal is CSI#1, the second channel state information sent by the terminal is CSI#2, and the third channel state information sent by the terminal is CSI#4 based on the first order.
[0405] Furthermore, the network device also stores an association between channel state information and a power offset parameter. For example, the association is: CSI#1 is associated with power offset parameter PO#1, CSI#2 is associated with power offset parameter PO#2, ..., and CSI#n is associated with power offset parameter PO#n. Furthermore, when the network device dynamically adjusts the transmit power of the PDSCH and / or CSI-RS, resulting in an adjustment of the power offset parameter, the network device can determine the adjusted power offset parameter, for example, the adjusted power offset parameter is PO#2. Based on the aforementioned association, the channel state information can be further determined to be CSI#2, thereby determining the channel state based on CSI#2.
[0406] For example, the first order includes the order of the identifiers of multiple sub-configurations in the reporting configuration of the first information from small to large, and the multiple sub-configurations are 3 sub-configurations, namely sub-configuration#1 identified as 1, sub-configuration#2 identified as 2, and sub-configuration#3 identified as 3.
[0407] Among multiple CSI-RS resources, CSI-RS resource#1 corresponds to 3 power offset parameters, namely PO#1 to PO#3, CSI-RS resource#2 corresponds to 3 power offset parameters, namely PO#4 to PO#6, CSI-RS resource#3 corresponds to 2 power offset parameters, namely PO#7 to PO#8, and CSI-RS resource#4 corresponds to 4 power offset parameters, namely PO#9 to PO#12.
[0408] When sub-configuration #1 is associated with CSI-RS resource #1 and CSI-RS resource #2, it can be further associated with PO #1 and PO #4. When the terminal determines that sub-configuration #1 is activated, after receiving the CSI-RS based on the CSI-RS resource #1 configuration and the CSI-RS resource #2 configuration, it can determine channel state information CSI #1 based on the CSI-RS measurement results and PO #1 and PO #4.
[0409] Sub-configuration #2, when associated with CSI-RS resource #3, can be further associated with PO #5. Upon determining that sub-configuration #2 is activated, the terminal receives a CSI-RS based on the CSI-RS resource #3 configuration and can determine channel state information (CSI #2) based on the CSI-RS measurement results and PO #5.
[0410] When sub-configuration #3 is associated with CSI-RS resource #4, it can be further associated with PO #7. When the terminal determines that sub-configuration #3 is activated and receives CSI-RS based on CSI-RS resource #4, it can determine channel state information CSI #3 based on the CSI-RS measurement results and PO #7.
[0411] The order of the three sub-configuration identifiers from small to large is sub-configuration#1, sub-configuration#2, and sub-configuration#3, and the corresponding channel state information order is CSI#1, CSI#2, and CSI#3. When the three sub-configurations are activated, the terminal sends multiple channel state information in the first order. It can first send CSI#1 in the reporting resources configured by sub-configuration#1, then send CSI#2 in the reporting resources configured by sub-configuration#2, and finally send CSI#3 in the reporting resources configured by sub-configuration#3.
[0412] In some embodiments, multiple channel state information can be determined based on dynamic signaling (e.g., at least one of DCI and MAC CE). For example, the terminal can first determine multiple sub-configurations based on the configuration information of the network device (e.g., RRC signaling), and determine the multiple activated sub-configurations based on the indication information of the network device (e.g., at least one of DCI and MAC CE). For any of the multiple sub-configurations, the terminal can receive CSI-RS on the CSI-RS resource associated with the sub-configuration, determine the measurement result of the CSI-RS, and determine the channel state information based on the measurement result and the adjusted power offset parameter. Then, for multiple sub-configurations, multiple channel state information can be determined, and the determined multiple channel state information can be sent to the network device.
[0413] In some embodiments, in addition to determining which channel state information the received multiple channel state information are based on the first order, the network device may achieve this effect in other ways, which is not limited by the present disclosure.
[0414] For example, the network device can configure multiple resources for sending channel state information for the terminal. There is an association between the resources and the channel state information. The terminal can send the channel state information on the resources associated with the channel state information. When the network device receives the channel state information, it can determine which channel state information is received based on the resource where the channel state information is located.
[0415] For example, the network device configures resources for the terminal for sending channel state information, and the resources are composed of multiple sub-resources, where the i-th sub-resource is used to send CSI#i. When the terminal sends CSI#1, CSI#2 and CSI#4 to the network device, the first sub-resource can be used to send CSI#1, the second sub-resource can be used to send CSI#2, and the fourth sub-resource can be used to send CSI#4. The network device can determine that the channel state information received in the first sub-resource is CSI#1, the channel state information received in the second sub-resource is CSI#2, and the channel state information received in the fourth sub-resource is CSI#4.
[0416] In some embodiments, receiving the first information determined by the terminal according to the power offset parameter includes: receiving at least one difference value sent by the terminal according to the second order.
[0417] In some embodiments, the first information includes first channel state information among the plurality of channel state information, and a difference between second channel state information other than the first channel state information and the first channel state information.
[0418] In some embodiments, the second order may be configured by the network device, or the second order may be agreed upon by a protocol, or the second order may be determined by the terminal and indicated to the network device. Regardless of whether the second order is determined by any of the above methods, the network device is known to the network device. Therefore, based on the second order of the received multiple channel state information, the network device can determine which channel state information each received at least one difference corresponds to, and further restore the corresponding channel state information based on the difference.
[0419] Since the difference in channel state information is generally smaller than the difference in channel state information, sending the difference to the terminal is beneficial to reducing the amount of data required for communication, so as to save communication resources.
[0420] Furthermore, the network device also stores the association between channel state information and power offset parameters. Therefore, the network device can determine the power offset parameter corresponding to each piece of channel state information. Furthermore, when the network device dynamically adjusts the transmit power of the PDSCH and / or CSI-RS, resulting in an adjustment of the power offset parameter, the network device can determine the channel state information corresponding to the adjusted power offset parameter and, based on this channel state information, determine the channel state.
[0421] In some embodiments, the terminal sends the first channel state signal and at least one difference value to the network device according to the second order. The first channel state signal and at least one difference value may be sent in multiple sending processes, for example, one difference value is sent in each sending process, and the network device can determine the order of the first channel state signal and the at least one difference value according to the sequence of the sending processes; or, the first channel state signal and at least one difference value may be carried in an uplink message in one sending process and sent to the network device. In this case, the first channel state signal and the at least one difference value may be set in multiple positions (for example, multiple bits) in the uplink information according to the first order, and the network device can determine the order of the first channel state signal and the at least one difference value according to the position of the channel state information in the uplink information.
[0422] In some embodiments, the second sequence includes at least one of the following:
[0423] An order of identifiers of the second channel state information, for example, an order of identifiers of the second channel state information from small to large, for example, an order of identifiers of the second channel state information from large to small;
[0424] An order for determining the magnitude of the power offset parameter of the second channel state information, for example, an order for determining the power offset parameter of the second channel state information from small to large, for example, an order for determining the power offset parameter of the second channel state information from large to small;
[0425] The order of the identifiers of the multiple sub-configurations in the reporting configuration of the first information, for example, the identifiers of the multiple sub-configurations are from small to large, for example, the identifiers of the multiple sub-configurations are from large to small.
[0426] In some embodiments, the channel state information may include at least one of the following: RI, PTI, PMI, and CQI.
[0427] Taking the PMI in the channel state information as an example, the first channel state information includes the channel state information with the largest corresponding value among multiple channel state information. The PMI may be a value used to determine the PM.
[0428] For example, each channel state information includes a PMI, so the multiple channel state information may include multiple PMIs. The first channel state information may be the PMI with the largest corresponding value among the multiple PMIs, and the second channel state information may be the PMI other than PMI#0 among the multiple PMIs.
[0429] For example, the multiple PMIs are 3 PMIs, namely PMI#1, PMI#2 and PMI#4, where the PMI with the largest corresponding value is PMI#2. Then the first channel state information is PMI#2, and the second channel state information includes PMI#1 and PMI#4.
[0430] The terminal may determine a difference D#12 between PMI#1 and PMI#2, and a difference D#42 between PMI#4 and PMI#2, wherein the first information includes PMI#2, D#12, and D#42. The terminal may send PMI#2, D#12, and D#42 to the network device in the second order.
[0431] For example, when the first channel state information includes channel state information having a maximum corresponding value among multiple channel state information, the terminal may further send a power offset parameter or a power offset parameter index corresponding to the channel state information having the maximum corresponding value to the network device. The terminal may determine the power offset parameter or the power offset parameter index corresponding to the channel state information having the maximum corresponding value based on a preset association relationship.
[0432] For example, the preset association relationship may include channel state information corresponding to power offset parameter values from small to large (or from large to small). Taking small to large as an example, the i-th power offset parameter corresponds to the i-th smallest power offset parameter. For example, taking four power offset parameters as an example, from small to large, they are PO#1, PO#2, PO#3, and PO#4. Then, the first power offset parameter is PO#1, the second power offset parameter is PO#2, the third power offset parameter is PO#3, and the fourth power offset parameter is PO#4. Based on the preset association relationship, the network device can determine that the four received power offset parameters are PO#1, PO#2, PO#3, and PO#4, respectively.
[0433] For example, the preset relationship may be power offset parameters corresponding to channel state information from small to large (or from large to small). Taking small to large as an example, the i-th power offset parameter corresponds to the power offset parameter corresponding to the i-th smallest channel state information. For example, taking the channel state information corresponding to four power offset parameters as an example, from small to large, they are CSI#3, CSI#4, CSI#1, and CSI#2. The power offset parameters corresponding to these four channel state information are PO#3, PO#4, PO#1, and PO#2, respectively. Then, the first power offset parameter is PO#3, the second power offset parameter is PO#4, the third power offset parameter is PO#1, and the fourth power offset parameter is PO#2. Based on the preset association relationship, the network device can determine that the four received power offset parameters are PO#3, PO#4, PO#1, and PO#2, respectively.
[0434] For example, the first channel state information may be located at a preset position in the second sequence, such as at a starting position or at an ending position, with the first channel state information being located at the starting position as an example. The second sequence includes the identifiers of the second channel state information arranged in ascending order, where the identifier of the second channel state information corresponding to D#12 is 2 and the identifier of the second channel state information corresponding to D#42 is 4. Then, in the second sequence, D#12 is arranged before D#42, and the terminal may send PMI#2, D#12, and D#42 to the network device in the order of PMI#2, D#12, and D#42.
[0435] The second order is known to the network device. Therefore, based on the second order, the network device can determine that the first PMI sent by the terminal is PMI#2, the second difference sent by the terminal is D#12, and the third difference sent by the terminal is D#42. The network device can then restore the difference to the corresponding channel state information. For example, the network device can add the difference to the first channel state information to obtain the channel state information corresponding to the difference. For example, for D#12, PMI#2 and D#12 can be added to obtain PMI#1. For D#42, PMI#2 and D#42 can be added to obtain PMI#4.
[0436] Furthermore, the network device also stores an association between channel state information and a power offset parameter. For example, the association is: PMI#1 is associated with power offset parameter PO#1, PMI#2 is associated with power offset parameter PO#2, ..., and PMI#n is associated with power offset parameter PO#n. Furthermore, when the network device dynamically adjusts the transmit power of the PDSCH and / or CSI-RS, resulting in an adjustment of the power offset parameter, the network device can determine the adjusted power offset parameter, for example, the adjusted power offset parameter is PO#2. Based on the aforementioned association, the channel state information can be further determined to be PMI#2, thereby determining the channel state based on PMI#2 (and also considering other information in the channel state information where PMI#2 is located).
[0437] In some embodiments, when receiving the first channel state information sent by the terminal, the network device may also receive the power offset parameter sent by the terminal for determining the first channel state information, so that the network device can accurately determine the power offset parameter associated with the first channel state information.
[0438] In some embodiments, in addition to determining which channel state information the at least one received difference corresponds to according to the second order, the network device may also achieve this effect in other ways, which is not limited by the present disclosure.
[0439] For example, the network device can configure multiple resources for sending channel state information for the terminal. There is an association between the resources and the channel state information. The terminal can send the first channel state information and at least one difference value in the resources associated with the channel state information. When the network device receives the channel state information, it can determine which channel state information the received difference corresponds to based on the resource where the channel state information is located.
[0440] For example, the network device configures n resources for sending channel state information for the terminal, and the resources are composed of multiple sub-resources, where the i-th sub-resource is used to send CSI#i. When the terminal sends PMI#1, PMI#2 and PMI#4 to the network device, the first sub-resource can be used to send PMI#2, the second sub-resource can be used to send D#12, and the fourth sub-resource can be used to send D#42. The network device can determine that the channel state information received in the first sub-resource is PMI#2, the channel state information received in the second sub-resource is D#12, and the channel state information received in the fourth sub-resource is D#42.
