[0052] 3. About Media Access Control Layer Control Element (MAC CE) Media Access Control Layer Control Element (MAC CE) is a path for exchanging control information between a terminal and a network. As its name suggests, it exchanges control information related to the MAC layer.

[0053] 4. Reference signal (RS) A reference signal is an important part of NR, and the RS includes a positioning reference signal (PRS) and a tracking reference signal (TRS). The PRS can be a reference for positioning, and the TRS can be a reference for phase.

[0054] In order to better understand the Transmission Configuration Indication (TCI) status setting method disclosed in the embodiment of the present application, a communication system to which the embodiment of the present application is applied will be described below.

[0055] As shown in Fig. 1, Fig. 1 is an architecture schematic diagram of a communication system provided in an embodiment of the present application. The communication system can include, but is not limited to, one network device and one terminal device, and the number and form of devices shown in Fig. 1 are merely examples and do not limit the embodiment of the present application, and may include two or more network devices and two or more terminal devices in actual application. The communication system shown in Fig. 1 is exemplified to include one network device 101 and one terminal device 102.

[0056] It should be noted that the technical solutions of the embodiments of the present application may be applied to various communication systems, such as a long term evolution (LTE) system, a 5th generation (5G) mobile communication system, a 5G new radio (NR) system, or other future new mobile communication systems, etc. The side link in the embodiments of the present application may also be referred to as a side link or a through link.

[0057] The network device 101 in the embodiment of the present application is an entity for transmitting or receiving a signal on the network side. For example, the network device 101 may be an evolved base station (eNB), a transmission reception point (TRP), a next generation base station (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiment of the present application does not limit the specific technology and specific device form adopted by the network device. The network device provided in the embodiment of the present application may be configured with a central unit (CU) and a distributed unit (DU), and the CU may be called a control unit. A CU-DU structure is adopted to divide the protocol layer of a network device, for example, a base station, to centrally control the functions of some protocol layers in the CU, and to distribute the functions of some or all of the remaining protocol layers to the DU, and to centrally control the DU by the CU.

[0058] The terminal device 102 in the embodiment of the present application is an entity for receiving or transmitting a terminal-side signal, for example, a mobile phone. The terminal device may be called a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The terminal device may be an automobile with a communication function, a smart automobile, a mobile phone, a wearable device, a tablet computer (Pad), a computer with a wireless transmission and reception function, 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, etc. The embodiments of the present application do not limit the specific technology and the specific device form adopted in the terminal device.

[0059] In Rel-16, beams such as PDCCH, PDSCH, PUSCH, PUCCH and each uplink / downlink reference signal are all individually indicated, and PDCCH and PUCCH activate one beam using MAC CE, while PDSCH and PUSCH indicate their respective beams based on DCI signaling. Currently, it is desirable to use a unified transmission configuration indication state (unified TCI state) to reduce signaling overhead. A unified TCI state, i.e., one unified TCI state, is used for beams corresponding to various channels and / or reference signals in one set. The unified TCI state may currently indicate uplink and downlink separately, i.e., it is used to indicate beams for downlink communication based on a separate DL TCI state and / or to indicate beams for uplink communication based on a separate UL TCI state. Or, the uplink and downlink are jointly indicated, that is, a joint transmission configuration indication state (joint TCI state) is used. The joint TCI state is simultaneously used for uplink and downlink beam indication. That is, if the base station indicates a separate DL TCI state to be used for one downlink, the TCI state can be used for at least one of the PDSCH and all or a part of the PDCCH (e.g., UE dedicated PDCCH) of the terminal, and / or a downlink reference signal, such as CSI-RS, SSB, PRS, and TRS, and if the base station indicates a separate UL TCI state to be used for one uplink, the TCI state can be used for at least one of the PUSCH and all or a part of the PUCCH and / or PRACH of the terminal, and / or an uplink reference signal, such as SRS, scheduling request.If the base station indicates one joint TCI state, the joint TCI state can be used for uplink and downlink channels and / or reference signals of the terminal.

[0061] The present application will now be described in detail with reference to the accompanying drawings.

[0062] As shown in Figure 2, Figure 2 is a flow chart schematic diagram of a transmission configuration indication (TCI) state setting method provided in an embodiment of the present disclosure. The embodiment of the present disclosure is applied to a terminal device. As shown in Figure 2, the method can include, but is not limited to, the following steps:

[0063] In step S201, receiving configuration information sent from a network device, the configuration information including at least one transmission configuration indication state corresponding to at least one transmission configuration indication code point.

[0064] In this embodiment, the terminal device can receive configuration information sent from the network device, and the network device can send the configuration information to the terminal device. The configuration information indicates a transmission configuration indication corresponding to an 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 a separate transmission configuration indication. The separate transmission configuration indication includes at least one of a separate uplink transmission configuration indication and a separate downlink transmission configuration indication.

[0065] In step S202, obtain a transmission setting indication status corresponding to the communication transmission according to the transmission setting indication code point.

[0066] In this embodiment, a transmission configuration indication (TCI) state pool is pre-configured in the terminal, and a transmission configuration indication state (TCI state) corresponding to a communication transmission can be obtained according to the transmission configuration indication code point, and the TCI state is one TCI state in the TCI state pool.

[0067] By implementing the embodiment of the present application, a transmission setting indication state corresponding to a communication transmission can be obtained according to the setting information sent from a network device, and multiple transmission setting indication states corresponding to multiple transmission setting indication code points can be obtained according to one setting information, which is advantageous in saving signaling resources and avoiding resource waste.

[0068] Receive setting information sent from a network device, and obtain a transmission setting indication state corresponding to a communication transmission based on the transmission setting indication code point, the setting information further including first indication information, the first indication information indicating that each element in the at least one transmission setting indication code point corresponds to a joint transmission setting indication, or indicating that each element in the at least one transmission setting indication code point corresponds to a separate transmission setting indication, the separate transmission setting indication including at least one of a separate uplink transmission setting indication and a separate downlink transmission setting indication.

[0069] In this embodiment, the code point is as shown in Table 1, where R is a reserved bit. The indicated first indication information can multiplex the R reserved bit or introduce a new bit. When the terminal device receives the first indication information, all elements in the code point correspond to a set of packet transmission indications, or all elements in the code point correspond to a set of packet transmission indications. For example, when the bit of the first indication information is displayed as “0”, it indicates that all TCIs corresponding to all TCI code points activated by the MAC CE are joint TCIs, and when the bit of the first indication information is displayed as “1”, it indicates that all TCIs corresponding to all TCI code points activated by the MAC CE are separate TCIs, or when the bit of the first indication information is displayed as “1”, it indicates that all TCIs corresponding to all TCI code points activated by the MAC CE are joint TCIs, and when the bit of the first indication information is displayed as “0”, it indicates that all TCIs corresponding to all TCI code points activated by the MAC CE are separate TCIs. The separate transmission setting indication includes at least one of a separate uplink transmission setting indication and a separate downlink transmission setting indication.

N,1 Corresponding to the above C N,2 is the second transmission configuration indication field TCI corresponding to the Nth TCI code point. N,2 By implementing the embodiment of the present application, one MAC CE configuration information can indicate that all elements in the TCI codepoint, i.e., the transmission configuration indications corresponding to all the TCI codepoints, are joint TCI or separate TCI, which is favorable for saving signaling resources and avoiding resource waste.

[0072] Receive setting information sent from a network device, and obtain a transmission setting indication state corresponding to a communication transmission based on the transmission setting indication code point, the setting information further including second indication information, the second indication information indicating that each element in the at least one transmission setting indication code point corresponds to a joint transmission setting indication or a separate transmission setting indication, and the separate transmission setting indication includes at least one of a separate uplink transmission setting indication and a separate downlink transmission setting indication.

The configuration information includes N+1 TCI code points, i.e., TCI i,1 and TCI i,2 corresponds to TCI code point i. For example, 0,1 and TCI 0,2 corresponds to TCI code point 0. Therefore, the second indication information includes N+1 indication fields, namely C0, C1...CN -1, C N The i-th indication field indicates that the i-th transmission configuration indication code point corresponds to a joint transmission configuration indication or a separate transmission configuration indication. For example, i When C is displayed as "0", it indicates that the TCI corresponding to TCI code point i is a joint TCI, and i When "1" is displayed, it indicates that the TCI corresponding to TCI code point i is a Separate TCI, or, for example, i When C is displayed as "1", it indicates that the TCI corresponding to TCI code point i is a joint TCI, and i is displayed as "0", it indicates that the TCI corresponding to the TCI code point i is a separate TCI. If the terminal device receives the second indication information, the terminal determines that each element in the TCI code point, i.e., each TCI code point, corresponds to a separate transmission setting indication or a joint transmission setting indication. The separate transmission setting indication includes at least one of a separate uplink transmission setting indication and a separate downlink transmission setting indication.

N,1 is the first transmission configuration indication field TCI corresponding to the Nth TCI code point. N,1 Corresponding to the above C N,2 is the second transmission configuration indication field TCI corresponding to the Nth TCI code point. N,2 The above N is an integer of 0 or more.

[0076] By implementing an embodiment of the present application, it is possible to indicate transmission setting instructions corresponding to each element in the TCI code point based on multiple instruction fields contained in one instruction information, thereby improving flexibility.

[0077] Optionally, the second indication information includes N indication fields, and the i-th indication field indicates that the i-th transmission setting indication code point corresponds to a joint transmission setting indication or a separate transmission setting indication, where N is the number of activated transmission setting indication code points included in the setting information.
