[0025] The embodiments of the present disclosure provide an information processing method, a terminal, a network device, a communication system, and a storage medium.

[0026] In a first aspect, an embodiment of the present disclosure proposes an information processing method, which is executed by a terminal, including: determining the TCI state of a CSI-RS; wherein the TCI state is one of N indicated TCI states; wherein N is a positive integer.

[0027] In the above embodiment, when there are multiple indicated TCI states, it can be clear which indicated TCI state is used by the CSI-RS; in this way, it can be clear which TCI state indicates the beam to be used for CSI-RS transmission, thereby improving the quality of wireless communication.

[0028] In combination with some embodiments of the first aspect, in some embodiments, the indicated TCI state is: an indicated joint TCI state, or an indicated downlink (DL) TCI state.

[0029] In the above embodiment, if the clearly indicated TCI state is the indicated joint TCI state, the beam indicated by the indicated joint TCI state can be used to transmit downlink channel information or downlink reference signal, or uplink channel information or uplink reference signal; or, if the clearly indicated TCI state is the indicated DL TCI state, the beam indicated by the indicated DL TCI state can be used to transmit downlink channel information or downlink reference signal, etc.; this can adapt to more transmission scenarios.

[0030] In combination with some embodiments of the first aspect, in some embodiments, the TCI state is the first TCI state among the N indicated TCI states, or the TCI state is the second TCI state among the N indicated TCI states.

[0031] In the above embodiment, it can be clarified that the TCI state of the CSI-RS is the first or second TCI state among the N indicated TCI states, thereby improving the flexibility of CSI-RS transmission based on the indicated TCI state.

[0032] In combination with some embodiments of the first aspect, in some embodiments, determining the TCI state of the CSI-RS includes: determining the TCI state of the CSI-RS when a first condition is met; wherein, satisfying the first condition includes at least one of the following: the interval between the CSI-RS transmission and the physical downlink control channel (PDCCH) transmission that schedules the CSI-RS is less than a first threshold value; the CSI-RS transmission and the physical downlink shared channel (PDSCH) transmission using at least two indicated TCI states occupy the same symbol, and the interval between the PDSCH transmission and the PDCCH transmission that schedules the PDSCH is greater than or equal to a second threshold value; the CSI-RS is not configured to follow a unified TCI state; and the CSI-RS is configured with a TCI state corresponding to the quasi coloation (QCL) information domain.

Optionally, the CSI-RS includes at least one of the following: a CSI-RS for channel state information measurement, a CSI-RS for beamforming measurement, and a CSI-RS for path loss estimation. Optionally, the SRS includes at least one of the following: an SRS for codebook-based channel state information measurement, an SRS for non-codebook-based channel state information measurement, an SRS for beamforming measurement, and an SRS for positioning measurement.

[0103] In some embodiments, the beam can be indicated by a transmission configuration indication (TCI) state or spatial relation information (spatialrelationinfo). To reduce signaling overhead, a unified transmission configuration indication (TCI) state can be introduced. Optionally, the unified TCI state may include: a downlink transmission configuration indication state (DL TCI state) and an uplink transmission configuration indication state (UL TCI state) for uplink and downlink indications, and / or a joint uplink and downlink transmission configuration indication state (joint TCI state). Optionally, if the network device indicates a DL TCI state for downlink, the DL TCI state may be used for the terminal's downlink channels (e.g., PDCCH and / or PDSCH, etc.) and / or downlink reference signals (e.g., CSI-RS, etc.). Optionally, if the network device indicates a UL TCI state for uplink, the UL TCI state may be used for the terminal's uplink channels (e.g., PUCCH and / or PUSCH, etc.) and / or uplink reference signals (e.g., SRS, etc.). If the network device indicates a joint TCI state, the joint TCI state can be used simultaneously for uplink channels (such as PUCCH and / or PUSCH, etc.), downlink channels (such as PDCCH and / or PDSCH, etc.), uplink reference signals (such as SRS, etc.) and / or downlink reference signals (such as CSI-RS, etc.).

[0104] In some embodiments, if a unified TCI state is configured for a multi-transmission reception point (MTRP), for an aperiodic (AP) CSI-RS, it is possible to configure whether to follow the unified TCI state, that is, whether to use the unified TCI state; if used, RRC configuration is required to use which of the two indicated joint TCI states or the indicated DL TCI states of the terminal; if not used, it is necessary to configure the used TCI state, that is, to configure a TCI state different from the two indicated joint TCI states or the indicated DL TCI states. Optionally, the CSI-RS can be a CSI-RS resource; that is, the CSI-RS and the CSI-RS resource can be interchangeable. Optionally, multiple is two or more.

[0105] In some embodiments, the indicated TCI state refers to a TCI state indicated to be used by MAC CE or DCI, rather than a TCI state in a TCI state list configured by RRC.

[0106] In some embodiments, if multiple transmission reception points (MTRPs) use a unified TCI state, multiple TCI states may exist (e.g., multiple indicated TCI states). However, since CSI-RS is transmitted by a single transmission reception point (STRP), it is necessary to specify which TCI state the CSI-RS uses. PDSCH, PDCCH, PUSCH, and PUCCH can specify which TCI state to use, or they can use multiple TCI states.

[0129] In some embodiments, the name of the first indication information is not limited, and it can be, for example, TCI status indication information.

[0130] Step S2102: The network device sends second indication information to the terminal.

[0131] In some embodiments, the terminal receives the second indication information sent by the network device.

[0132] In some embodiments, the second indication information is carried in a MAC CE. Optionally, the second indication information may also be carried in another message or signaling; for example, it may be carried in a DCI. Optionally, the MAC CE carrying the second indication information may be the same MAC CE as the MAC CE carrying the first indication information, or a different MAC CE.

[0133] In some embodiments, the second indication information is used to determine whether each indicated TCI state is the first or the second of the at least two indicated TCI states.

[0134] In some embodiments, the second indication information is used to determine whether each indicated joint TCI state is the first or the second of the at least two indicated joint TCI states.

[0135] In some embodiments, the second indication information is used to determine whether each indicated DL TCI state is the first or the second of the at least two indicated DL TCI states.

[0136] In some embodiments, the second indication information is used to determine whether each indicated UL TCI state is the first or the second of the at least two indicated UL TCI states.

[0138] Optionally, the second indication information is used by the terminal to determine that each indicated TCI state is the Lth TCI state among at least two indicated TCI states.

[0139] In some embodiments, the second indication information is used by the terminal to determine the TCI state of the CSI-RS. Optionally, the second indication information and N indicated TCI states are used by the terminal to determine the TCI state of the CSI-RS; the N indicated TCI states are determined by the terminal based on at least one indicated TCI state indicated by the first indication information.

[0140] In some embodiments, the second indication information is carried in a MAC CE; the MAC CE is used by the terminal to determine whether the TCI state of each indication is the first or second of at least two indicated TCI states. Optionally, the MAC CE is used to indicate whether the TCI state of each indication is the first or second of the at least two indicated TCI states.

[0141] Exemplarily, the network device sends a MAC CE to the terminal, and the MAC CE is used to indicate whether each indicated TCI state is the first or the second of at least two indicated TCI states. Exemplarily, the second indication information uses 1 bit to indicate whether each indicated TCI state is the first or the second of at least two indicated TCI states; wherein, the bit indication '1' indicates that the corresponding indicated TCI state is the first of at least two indicated TCI states, and the bit indication '0' indicates that the corresponding indicated TCI state is the second of at least two indicated TCI states.

[0143] In some embodiments, the name of the second indication information is not limited, and it can be, for example, TCI status indication information, first TCI status indication information, or second TCI status indication information.

[0144] In some embodiments, the indicated TCI state, unified TCI state, indicated joint TCI state, indicated DL TCI state and / or indicated UL TCI state, etc., may all be referred to as TCI states.

[0145] In step S2103 , the terminal determines the TCI state of the CSI-RS.

[0146] In some embodiments, the terminal determines N indicated TCI states; and determines the TCI state of the CSI-RS based on the N indicated TCI states.

[0147] In some embodiments, the terminal determines N indicated TCI states based on the first indication information; and determines the TCI state of the CSI-RS based on the second indication information and the N indicated TCI states. Here, since the first indication information is used to indicate at least one indicated TCI state, the terminal may determine the N indicated TCI states based on the at least one indicated TCI state indicated by the first indication information; since the second indication information is used to indicate that each indicated TCI state is the first, second, or Lth of the at least one indicated TCI state, the terminal may determine the TCI state of the CSI-RS as the first, second, or Lth of the at least one indicated TCI state based on the second indication information; L is a positive integer, and L is less than or equal to N.

[0148] Optionally, the TCI state is one of N indicated TCI states; where N is a positive integer.

[0149] Optionally, the TCI state is a first TCI state among the N indicated TCI states, or the TCI state is a second TCI state among the N indicated TCI states. Exemplarily, the first TCI state may be an indicated joint TCI state or an indicated DL TCI state. Exemplarily, the second TCI state may be an indicated joint TCI state or an indicated DL TCI state.

[0150] In some embodiments, when a first condition is met, the TCI state of the CSI-RS is determined.

[0151] Optionally, satisfying the first condition includes at least one of the following: the interval between the CSI-RS transmission and the PDCCH transmission that schedules the CSI-RS is less than a first threshold value; the CSI-RS transmission and the PDSCH transmission using at least two indicated TCI states occupy the same symbol, and the interval between the PDSCH transmission and the PDCCH transmission that schedules the PDSCH is greater than or equal to a second threshold value; the CSI-RS is not configured to follow a unified TCI state; and the CSI-RS is configured with a TCI state corresponding to the quasi-co-site QCL information domain.

[0152] Optionally, the CSI-RS is not configured to follow a unified TCI state, including: the CSI-RS is not configured by the higher layer to follow a unified TCI state; and / or the CSI-RS is configured with a TCI state corresponding to the quasi-co-site QCL information domain, including: the CSI-RS is configured by the higher layer with a TCI state corresponding to the quasi-co-site QCL information domain.

[0153] Optionally, the higher layer may be an RRC layer or the like.

[0154] Optionally, the first threshold value may be a beam switching time (beamSwitchTiming). Optionally, the first threshold value may be a first time unit; the first time unit may be a first duration, at least one symbol, or at least one time slot.

[0155] Optionally, the second threshold value may be a QCL duration (time duration for QCL). Optionally, the second threshold value may be a second time unit; the second time unit may be a second duration, at least one symbol, or at least one time slot.

[0156] Optionally, the QCL information field includes a first QCL information field and a second QCL information field; the first QCL information field and the second QCL information field correspond to different QCL types.

[0157] Optionally, if the CSI-RS is not configured by the higher layer to follow the unified TCI state, then the CSI-RS needs to be configured by the higher layer with a TCI state other than the unified TCI state.

[0158] Optionally, the higher layer configures the TCI state corresponding to the quasi-co-located QCL information field. Since the CSI-RS is not configured by the higher layer to follow the unified TCI state, the higher layer needs to configure the CSI-RS with a different TCI state than the unified TCI state, i.e., configure the corresponding TCI state in the quasi-co-located QCL information field.

[0159] Optionally, CSI-RS transmission and PDSCH transmission using at least two indicated TCI states occupy the same symbol, and the interval between the PDSCH transmission and the PDCCH transmission scheduling the PDSCH is greater than or equal to a second threshold. That is, while receiving the CSI-RS, the terminal needs to use both indicated TCI states to receive the PDSCH on the same symbol. Therefore, the terminal needs to first buffer the CSI-RS using both indicated TCI states in the same symbol. After decoding the DCI that schedules the CSI-RS, the terminal learns which CSI-RS the DCI schedules and also learns that the CSI-RS is configured by RRC not to follow a unified TCI state. However, the terminal only uses both indicated TCI states to buffer the CSI-RS. Therefore, the terminal can only receive the CSI-RS using the first or second of the two indicated TCI states. In this case, it is optionally determined that the CSI-RS is received using the first of the two indicated TCI states.

[0160] In some embodiments, when single DCI (S-DCI) schedules MTRP transmission, the TCI state of the CSI-RS is determined when the interval between the CSI-RS and the PDCCH scheduling the CSI-RS is less than a first threshold.

[0161] In some embodiments, the N indicated TCI states are determined based on at least one first indication information.

[0162] In some embodiments, the N indicated TCI states are determined based on the first indication information and the second indication information.

[0163] In some embodiments, the TCI status of the CSI-RSI is determined based on the first indication information and the second indication information.

[0164] Optionally, in the case where the first first indication information is used to indicate M indicated TCI states, the N indicated TCI states are: the M indicated TCI states indicated by the first indication information, where M is a positive integer. Take M=2 as an example. For example, the first first indication information indicates two indicated TCI states, and the two indicated TCI states include a first indicated TCI state and a second indicated TCI state. The second first indication information indicates that the first indicated TCI state is the first of the two indicated TCI states, and the second indicated TCI state is the second of the two indicated TCI states. The terminal determines that the N indicated TCI states are the first indicated TCI state and the second indicated TCI state.

[0165] Optionally, when the second first indication information updates K of the M indicated TCI states indicated by the first first indication information, the N indicated TCI states are: the K indicated TCI states indicated by the second first indication information, or the N indicated TCI states are: the K indicated TCI states indicated by the second first indication information and the indicated TCI states other than K of the M indicated TCI states indicated by the first first indication information; where K is a positive integer and K is less than or equal to M. For example, when M=2 and K=2, the second first indication information also indicates two indicated TCI states, which include a third indicated TCI state and a fourth indicated TCI state. The second indication information indicates that the third indicated TCI state is the first of the two indicated TCI states, and the fourth indicated TCI state is the second of the two indicated TCI states. Therefore, the terminal determines that the N indicated TCI states are the two indicated TCI states indicated by the second first indication. For example, if M=2 and K=1, the second first indication information indicates only one indicated TCI state, which is the third indicated TCI state. The second indication information indicates that the third indicated TCI state is the first of the two indicated TCI states. The terminal then determines that the N indicated TCI states are the third indicated TCI state indicated by the second first indication information and the second indicated TCI state indicated by the first first indication information.

[0166] Exemplarily, the network device sends a first first indication message to the terminal, and the first first indication message indicates two indicated TCI states; the N indicated TCI states determined by the terminal are the two indicated TCI states indicated by the first indication message. For example, the first first indication message indicates two indicated TCI states, and the two indicated TCI states include a first indicated TCI state and a second indicated TCI state. The second indication message indicates that the first indicated TCI state is the first of the two indicated TCI states, and the second indicated TCI state is the second of the two indicated TCI states. The terminal determines that the N indicated TCI states are the first indicated TCI state and the second indicated TCI state.

[0167] Exemplarily, based on the above embodiment, the network device sends a second first indication message to the terminal, and the second first indication message indicates that the TCI state of the first indication in the first first indication message is updated. The terminal determines that the TCI states of the N indications are: the TCI state of the first indication updated by the second first indication message and the TCI state of the second indication indicated by the first first indication message; or, the terminal determines that the TCI states of the N indications are: the TCI state of the first indication updated by the second first indication message. For example, the second first indication message only indicates one TCI state, and the TCI state of the indication is the TCI state of the third indication. The second indication message indicates that the TCI state of the third indication is the first of the two TCI states. Then, the terminal determines that the TCI states of the N indications are the TCI state of the third indication indicated by the second first indication message and the TCI state of the second indication indicated by the first first indication message.

[0168] In some embodiments, when the DCI carrying the first indication information is not received and the MAC CE carrying the first indication information is received, and the MAC CE is used to activate at least one indicated TCI state corresponding to each of multiple code points in the TCI state indication field of the DCI, then the terminal determines the N indicated TCI states as: at least one indicated TCI state indicated by a predetermined code point or any code point or a minimum code point among the multiple code points.

[0169] Optionally, the predetermined code point is pre-set; for example, the predetermined code point may be the first code point or any code point, etc. Optionally, the predetermined code point may be a minimum code point among multiple code points corresponding to at least two indicated joint TCI states, or code points corresponding to at least two indicated DL TCI states.

[0170] Optionally, the minimum code point is the code point with the smallest value among the code points. The value of the code point can be represented by the bits that indicate the code point. For example, if there are five code points, and the bits corresponding to the five code points are: 000, 001, 010, 011, and 100, then the code point corresponding to the bits "000" is the minimum code point.

[0171] Exemplarily, a network device sends DCI and MAC CE to a terminal, wherein first indication information is carried in the DCI and MAC CE; after receiving the MAC CE carrying the first indication information but before receiving the DCI, the terminal determines that the N indicated TCI states may be at least one indicated TCI state corresponding to one of the multiple code points in the TCI state indication field of the DCI, because the MAC CE is used to indicate at least one indicated TCI state corresponding to one of the multiple code points. Optionally, one of the multiple code points may be a predetermined code point, an arbitrary code point, or a minimum code point. Optionally, the terminal may also determine that the N indicated TCI states may be the minimum code point among the code points corresponding to at least two indicated TCI states in the multiple code points. Optionally, the at least two indicated TCI states include at least two indicated joint TCI states or at least two indicated DL TCI states.
