[0085] To better understand a method for configuring a transmission configuration indication (TCI) state disclosed in an embodiment of the present application, a communication system applicable to the embodiment of the present application will be described first below.

[0086] Please refer to Figure 1 , Figure 1 which is a schematic diagram of an architecture of a communication system provided for an embodiment of the present application. The communication system may include, but is not limited to, a network device and a terminal device, Figure 1The number and form of the devices shown are only for illustration and do not constitute a limitation on the embodiments of the present application. In practical applications, there may include two or more network devices and two or more terminal devices. Figure 1 Taking a communication system including a network device 101 and a terminal device 102 as an example.

[0087] It should be noted that the technical solutions of the embodiments of the present application can be applied to various communication systems. For example: Long Term Evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems, etc. It should also be noted that the sidelink in the embodiments of the present application can also be referred to as a sidelink or a direct link.

[0088] The network device 101 in the embodiments of the present application is an entity on the network side for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a Wireless Fidelity (WiFi) system, etc. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the network device. The network device provided by the embodiments of the present application can be composed of a central unit (CU) and a distributed unit (DU). Among them, the CU can also be called a control unit. Adopting the CU-DU structure can split the protocol layer of the network device, such as a base station. The functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0089] The terminal device 102 in the embodiments of the present application is an entity on the terminal side for receiving or transmitting signals, such as a mobile phone. The terminal device can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The terminal device can be an automobile with communication functions, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, and so on.

[0090] In Rel-16, the beams of PDCCH, PDSCH, PUSCH, PUCCH, and various uplink and downlink reference signals are independently indicated. The PDCCH and PUCCH use MAC CE to activate a beam, while the PDSCH and PUSCH are indicated their respective beams according to DCI signaling. Currently, in order to reduce signaling overhead, it is desired to use a unified transmission configuration indication state (unified TCI state). The unified TCI state means that one unified TCI state is used for the beams corresponding to multiple channels and / or reference signals within a set. The unified TCI state may currently be indicated separately for the uplink and downlink, that is, according to a separate downlink transmission configuration indication state (separate DL TCI state) for beam indication in downlink communication and / or a separate uplink transmission configuration indication state (separate UL TCI state) for beam indication in uplink communication. Or jointly indicate for the uplink and downlink, that is, use a joint transmission configuration indication state (joint TCI state). The joint TCI state is used for beam indication in both the uplink and downlink at the same time. That is, if the base station indicates a separate DL TCI state for the downlink, then this TCI state can be used for the PDSCH of the terminal and all or part of the PDCCH (such as UE dedicated PDCCH), and / or at least one of the downlink reference signals such as CSI-RS, SSB, PRS, TRS; if the base station indicates a separate UL TCI state for the uplink, then this TCI state can be used for the PUSCH of the terminal and all / part of the PUCCH and / or PRACH, and / or at least one of the uplink reference signals such as SRS, scheduling request. If the base station indicates a joint TCI state, then this joint TCI state can be used for the channels and / or reference signals in both the uplink and downlink of the terminal.

[0091] It can be understood that the communication system described in the embodiments of this application is to more clearly illustrate the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided by the embodiments of this application. Those of ordinary skill in the art know that with the evolution of the system architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of this application are equally applicable to similar technical problems.

[0092] The method and device for configuring the transmission configuration indication TCI state provided by this application will be introduced in detail below with reference to the accompanying drawings.

[0093] Please refer to Figure 2 ,Figure 2 It is a schematic flow chart of a method for configuring a transmission configuration indication (TCI) state provided by an embodiment of the present application. The embodiments of the present disclosure are applied to a terminal device. As Figure 2 shown, the method may include but is not limited to the following steps:

[0094] Step S201: Receive configuration information sent by a network device, where the configuration information includes at least one transmission configuration indication state corresponding to at least one transmission configuration indication code point.

[0095] In this embodiment, the terminal device may receive the configuration information sent by the network device, and the network device may send the configuration information to the terminal device. The configuration information is used to indicate the transmission configuration indication corresponding to the element in at least one transmission configuration indication code point (TCI codepoint), and the transmission configuration indication includes at least one of a joint transmission configuration indication and an independent transmission configuration indication. The independent transmission configuration indication includes at least one of an independent uplink transmission configuration indication and an independent downlink transmission configuration indication.

[0096] Step S202: Obtain the transmission configuration indication state corresponding to the communication transmission according to the transmission configuration indication code point.

[0097] In this embodiment, the terminal is pre-configured with a transmission configuration indication (TCI) state pool. Based on the transmission configuration indication code point, the transmission configuration indication state (TCI state) corresponding to the communication transmission can be obtained according to the code point. The TCI state is a TCI state in the TCI state pool.

[0098] By implementing the embodiments of the present application, the transmission configuration indication state corresponding to the communication transmission can be obtained according to the configuration information sent by the network device, and multiple transmission configuration indication states corresponding to multiple transmission configuration indication code points can be obtained according to one configuration information. In this way, signaling resources can be saved, which is beneficial to avoiding resource waste.

[0099] Receive the configuration information sent by the network device, and obtain the transmission configuration indication state corresponding to the communication transmission according to the transmission configuration indication code point; the configuration information further includes:

[0100] First indication information, the first indication information is used to indicate that each element in the at least one transmission configuration indication code point corresponds to a joint transmission configuration indication, or

[0101] is used to indicate that each element in the at least one transmission configuration indication code point corresponds to an independent transmission configuration indication, where the independent transmission configuration indication includes at least one of an independent uplink transmission configuration indication and an independent downlink transmission configuration indication.

[0102] In this embodiment, the code points are shown in Table 1, where R is a reserved bit. The first indication information can reuse the R reserved bit or introduce a new bit. If the terminal device receives the first indication information, all elements in the code points correspond to independent transmission configuration indications, or all elements in the code points correspond to independent transmission configuration indications. For example, if the bit of the first indication information is shown as "0", it means that the TCIs corresponding to all the activated TCI code points in this MAC CE are joint TCIs; if the bit of the first indication information is shown as "1", it means that the TCIs corresponding to all the activated TCI code points in this MAC CE are independent TCIs. Or, for example, if the bit of the first indication information is shown as "1", it means that the TCIs corresponding to all the activated TCI code points in this MAC CE are joint TCIs; if the bit of the first indication information is shown as "0", it means that the TCIs corresponding to all the activated TCI code points in this MAC CE are independent TCIs. The independent transmission configuration indication includes at least one of an independent uplink transmission configuration indication and an independent downlink transmission configuration indication.

[0103]

[0104] Table 1

[0105] C N，1 is the first information indication field and C N，2 is the second information indication field. The C N，1 corresponds to the first transmission configuration indication field TCI of the Nth TCI code point N，1 and the C N，2 corresponds to the second transmission configuration indication field TCI of the Nth TCI code point N，2 . By implementing the embodiments of the present application, it is possible to make the transmission configuration indications corresponding to all elements, that is, all TCI code points, in the TCI code points indicated by the MAC CE configuration information be joint TCIs or independent TCIs, saving signaling resources and facilitating the avoidance of resource waste.

[0106] Receive the configuration information sent by the network device, and obtain the transmission configuration indication status corresponding to the communication transmission according to the transmission configuration indication code point; the configuration information further includes:

[0107] Second indication information, which is used to indicate that each element in the at least one transmission configuration indication code point corresponds to a joint transmission configuration indication or an independent transmission configuration indication respectively, where the independent transmission configuration indication includes at least one of an independent uplink transmission configuration indication and an independent downlink transmission configuration indication.

[0108] In this embodiment, the code points are shown in Table 2, where R is a reserved bit. The configuration information includes N + 1 TCI code points, namely TCI i，1 and TCI i，2 correspond to TCI code point i. For example, TCI 0，1 and TCI 0，2 correspond to TCI code point 0. Therefore, the second indication information includes N + 1 indication fields, namely:

[0109] C 0 , C 1 ......C N-1 , C N . The i-th indication field is used to indicate the joint transmission configuration indication or the independent transmission configuration indication corresponding to the i-th transmission configuration indication code point. For example, C i displayed as "0" indicates that the TCI corresponding to TCI code point i is a joint TCI, and C i displayed as "1" indicates that the TCI corresponding to TCI code point i is an independent TCI; or for example, C i displayed as "1" indicates that the TCI corresponding to TCI code point i is a joint TCI, and C i displayed as "0" indicates that the TCI corresponding to TCI code point i is an independent TCI. If the terminal device receives the second indication information, the terminal determines each element in the TCI code points, that is, each TCI code point corresponds to an independent transmission configuration indication or a joint transmission configuration indication respectively. The independent transmission configuration indication includes at least one of an independent uplink transmission configuration indication and an independent downlink transmission configuration indication.
