Otherwise, using the same TCI state set for different BWPs, especially if the BWP frequency domain spacing is large, will lead to suboptimal beam selection, and the terminal will need to switch between different BWPs to measure the corresponding reference RS or SS / PBCH block.

Detailed Implementation

[0017] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0018] Figure 1The wireless communication system involved in this application is illustrated. The wireless communication system can operate on a high-frequency band and may be a future-evolving fifth-generation (5G) mobile communication system, a new radio (NR) system, a machine-to-machine (M2M) communication system, etc. As shown, the wireless communication system 100 may include: one or more network devices 101, one or more terminals 103, and core network devices 105. Specifically, the network device 101 may be a base station, which can be used to communicate with one or more terminals, or to communicate with one or more base stations that have partial terminal functions (e.g., communication between macro base stations and micro base stations, such as access points). The base station may be a base transceiver station (BTS) in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, an evolved Node B (eNB) in an LTE system, or a base station in a 5G system or a NR system. Additionally, the base station can also be an Access Point (AP), Trans Transmission Point (TRP), Central Unit (CU), or other network entities, and may include some or all of the functions of the above network entities. Core network equipment 105 includes core network-side equipment such as a Serving Gateway (SGW). Terminal 103 can be distributed throughout the entire wireless communication system 100, and can be stationary or mobile. In some embodiments of this application, terminal 103 can be a mobile device (such as a smartphone), a mobile station, a mobile unit, an M2M terminal, a wireless unit, a remote unit, a user agent, a mobile client, etc.

[0019] It needs to be explained that, Figure 1 The wireless communication system 100 shown is only for the purpose of more clearly illustrating the technical solution of this application and does not constitute a limitation on this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new service scenarios, the technical solution provided by this application is also applicable to similar technical problems.

[0020] The relevant technologies involved in this application are described below.

[0021] Currently, in modern NR designs, a terminal can be configured with multiple downlink DL BWPs or uplink UL BWPs, and can transmit relatively dynamically on different BWPs through methods such as DCI / Media Access Control Layer Control Unit (MAC CE).

[0022] However, many configurations in the current beam management mechanism cannot effectively support the aforementioned dynamic BWP switching behavior. For example, in NR, the network can be configured with K Transmission Configuration Indicator (TCI) states. If K > 8, then 8 states need to be selected from the K states via MAC CE, corresponding to the 3-bit indication information in the DCI; if K <= 8, then the K states are matched with the 3-bit indication information in the DCI. The specific mapping method can be specified by the protocol or configured by the network. If dynamic switching of BWPs is to be supported (e.g., dynamic switching of 4 BWPs), if the 8 states need to be mapped to 4 BWPs, then each BWP will only have an average of 2 states, which will greatly limit the selection and indication of beams on each BWP (corresponding to 2 different beam indications). Therefore, the existing scheme and the dynamic BWP scheme cannot work together efficiently.

[0023] To address the aforementioned problems, this application proposes the following embodiments, which will be described in detail below with reference to the accompanying drawings.

[0024] Please see Figure 2 , Figure 2 This application provides a transmission configuration method, applied to the above-described example communication system. The method includes: In section 201, the network device indicates a Transmission Configuration Indicator (TCI) state set to the terminal. The TCI state set is configured for the terminal's Bandwidth Partial (BWP) and is used to indicate the Quasi-co-location assumption set transmitted by the terminal on the BWP.

[0025] The quasi-co-location hypothesis set refers to a set of multiple quasi-co-location hypotheses. Each quasi-co-location hypothesis may contain one or more reference signals. If a target signal is associated with this quasi-co-location hypothesis, it can be considered that the target signal is similar to or the same as some large-scale information of the channel corresponding to the one or more of the above signals. The specific large-scale information may also be included in the quasi-co-location hypothesis.

[0026] As can be seen, in this embodiment, the network device indicates a Transmission Configuration Index (TCI) state set to the terminal. This TCI state set is configured for the terminal's bandwidth portion (BWP), and it is used to indicate the Quasi-co-location assumption set for transmission on the BWP. It is evident that by configuring a separate TCI state set for each BWP, flexibility can be effectively achieved. For example, the reference signals (CSI-RS, SS / PBCH block) included in the TCI state are different for different bandwidth portions of the BWP. Therefore, different TCI state sets need to be configured for different BWPs to achieve better beam management. Otherwise, using the same TCI state set for different BWPs, especially if the BWP frequency domain spacing is large, will lead to suboptimal beam selection, and the terminal will need to switch between different BWPs to measure the corresponding reference RS or SS / PBCH block.

[0027] In one possible example, the TCI state set includes at least one TCI state set, each TCI state set corresponding to one or more BWPs of the terminal.

[0028] In one possible example, the TCI state set includes K TCI states, where K is a positive integer greater than 8; the method further includes: the network device selecting a target TCI state set corresponding to the target BWP from the TCI state set; the network device selecting 8 TCI states from the K TCI states in the target TCI state set, the 8 TCI states corresponding to 3 bits of downlink control information (DCI) indication information, the DCI being used to indicate the quasi-co-address assumption state currently used by the target BWP for transmission.

[0029] The quasi-co-location assumption state may include one or more reference signals. If a target signal is associated with this quasi-co-location assumption, it can be considered that the target signal is similar to or the same as some large-scale information of the channel corresponding to the one or more of the above signals. The specific large-scale information may also be included in the quasi-co-location assumption.

[0030] In one possible example, the TCI state set includes K TCI states, where K is a positive integer less than or equal to 8; the method further includes: the network device selecting a target TCI state set corresponding to the target BWP from the TCI state set; the K TCI states in the target TCI state set correspond to 3 bits of downlink control information (DCI) indication information, whereby the DCI is used to indicate the quasi-co-address assumption state currently used by the target BWP for transmission.

[0031] For example, if the network device selects a target TCI state set corresponding to the target BWP, which includes 6 states, the correspondence between these 6 states and the indication information of the 3 bits of DCI can be shown in Table 1.

[0032] Table 1 In one possible example, the TCI state set includes X TCI state sets, where X is a positive integer; the method further includes: the network device configuring the X TCI state sets for the terminal, and / or, for some or all TCI state sets, using a Media Access Control Layer Control Unit (MAC CE) to select eight corresponding states, each TCI state set corresponding to one or more BWPs; the network device instructing the terminal to activate the BWP, the instruction being used by the terminal to determine the TCI state set corresponding to the BWP, and / or to determine the eight states corresponding to the BWP.

[0033] In one example, the network device can configure X TCI state sets for the terminal to indicate that the BWP of the terminal is activated, and the indication is used by the terminal to determine the TCI state set corresponding to the BWP.

[0034] In another example, the network device may use a Media Access Control Layer Control Unit (MAC CE) to select eight corresponding states for some or all of the TCI state set, and instruct the terminal to activate the BWP, the instruction being used by the terminal to determine the eight states corresponding to the BWP.

[0035] As can be seen in this example, the network device configures X sets of TCI states, and / or, for some or all of the TCI state sets, uses the Media Access Control Layer (MAC) CE to select the corresponding 8 states, enabling the terminal to determine the TCI state set corresponding to the BWP, and / or determine the 8 states corresponding to the BWP. This further improves flexibility.

[0036] In one possible example, the TCI state set includes X TCI state sets, each TCI state set including K TCI states, where K is a positive integer greater than 8; the method further includes: when the network device instructs the terminal's BWP to be activated, using MAC CE to select 8 states contained in the TCI state set corresponding to the BWP from the X TCI state sets, wherein the X TCI state sets are pre-configured by higher-layer signaling, and X is a positive integer.

[0037] As can be seen in this example, when K is greater than 8, the network device can directly use MAC CE to select the 8 states contained in the TCI state set corresponding to the BWP when activating the BWP of the activating terminal, thereby improving configuration efficiency.

[0038] In one possible example, the method further includes: when the network device instructs the terminal's BWP to be activated, configuring the corresponding TCI state set for the BWP, and / or selecting the corresponding 8 states using the Media Access Control Layer Control Unit (MAC CE).

[0039] The network device uses eight states selected by MAC CE to indicate the quasi-co-location assumption state indicated by 3 bits in DCI when the terminal transmits on the BWP.
