In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific examples. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the protection scope of the embodiments of the present application. The embodiment of the present application includes at least part of the following content.

In the NR system, network devices can activate a group (one) of TCI states or a group of TCI state pairs through some MAC CEs.

Specifically, for example, a terminal-specific (UE-specific) physical downlink control channel (Physical Downlink Control Channel, PDCCH) MAC CE for indicating the TCI state may be as shown in Figure 2. Specifically, the serving cell identifier (Serving The Cell ID) field occupies 5 bits of octet (Octet, Oct) 1, and the control resource set (Control Resource Set, CORESET) identification (Identity, ID) field in MAC CE occupies 3 bits of Oct 1 and Oct 1 bit of Oct 2, and the TCI state ID (TCI state ID) field in MAC CE occupies 7 bits of Oct 2.

For example, a terminal-specific (UE-specific) physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) MAC CE for activating or deactivating the TCI state may be as shown in FIG. 3 , specifically, the serving cell in the MAC CE The identification (Serving Cell ID) field occupies 5 bits of Oct 1, the CORESET ID field in MAC CE occupies 1 bit of Oct 1, and the bandwidth part (Band Width Part, BWP) ID field in MAC CE occupies 2 bits of Oct 1 T _i in the MAC CE represents the TCI state ID i, that is, each TCI state ID occupies 1 bit.

Specifically, for example, the enhanced terminal-specific (UE-specific) PDSCH MAC CE for activating or deactivating the TCI state may be as shown in FIG. 4 , specifically, the Serving Cell ID field in the MAC CE occupies Oct 5 bits of 1, the Band Width Part (BWP) ID field in MAC CE occupies 2 bits of Oct 1, the C ₀ field in MAC CE occupies 1 bit, and the C ₀ field is used to indicate the TCI state ID Whether _0,2 exists, ..., the _CN field in the MAC CE occupies 1 bit, and the _CN field is used to indicate whether the TCI state ID _N,2 exists.

For another specific example, the MAC CE can be used to activate the uplink and downlink TCI status identifier pair, as shown in Figure 5, the E field in the MAC CE is used to indicate whether the MAC CE is used for "joint beam indication" or "single beam indication" , the C field in the MAC CE is used to indicate whether there is an octet with an uplink TCI status ID (only required for "individual beam indication"), and the F field in the MAC CE is used to indicate whether the terminal device should consider the previous The octets are either padding or as downstream TCI status.

In the NR system, the TCI state used to represent the beam in the TCI state frame is not only distinguished between the uplink and downlink (the downlink uses the TCI state representation, the uplink uses the spatial relationship (spatial relationship) representation), but also different channels and reference Different signaling processes are used between the signals. A unified TCI state framework (unified TCI state frame work) was subsequently introduced, with the purpose of unifying the TCI state list and related signaling as much as possible in these two dimensions. This unified TCI state framework stipulates that either a joint (joint) TCI state is adopted, that is, the same TCI state (joint TCI state) is used for both uplink and downlink, or a separate TCI state is used, that is, the downlink and uplink TCI states are separated. express. However, when separate TCI states are used, the TCI state indicated in the downlink control information (Downlink Control Information, DCI) is either a downlink TCI state, or an uplink TCI state, or a pair of TCI states (that is, a pair of uplink and downlink TCI states). TCI state).

In order to better understand the embodiments of the present application, the problems solved in the present application will be described.

The above-mentioned MAC CE cannot distinguish the uplink and downlink attributes of the TCI state identifier, and certainly cannot identify the pairing relationship between the uplink and downlink TCI state identifiers. In addition, in the above example, although it is assumed that there is at least one downlink TCI status identifier in the MAC CE, however, it is always assumed that the downlink (downlink, DL) TCI status identifier is in the front when pairing, and the uplink (uplink, UL) TCI status logo on the back.

Based on the above problems, the present application proposes a scheme for activating the TCI state. The network device can activate at least one downlink TCI state in the downlink TCI state list and/or at least one uplink TCI state in the uplink TCI state list through the MAC CE, or , the network device can activate the TCI states in the n TCI state groups in the TCI state group list through the MAC CE. In this way, the solution for activating the TCI state of the network device is optimized.

The technical scheme of the present application is described in detail below through specific examples.

In this way, the solution for activating the TCI state of the network device is optimized.

Among them, the first parameter corresponding to the fifth TCI state is used to indicate whether the fifth TCI state and the fourth TCI state are paired TCI states, and the first parameter corresponding to the seventh TCI state is used to indicate the seventh TCI state Whether the state and the sixth TCI state are paired TCI states, and the first parameter corresponding to the ninth TCI state is used to indicate whether the ninth TCI state and the eighth TCI state are paired TCI states.

It should be noted that in FIG. 7 , DL represents a downlink TCI state, and UL represents an uplink TCI state. Specifically, the fourth TCI state (downlink TCI state) and the fifth TCI state (uplink TCI state) are paired TCI states, the sixth TCI state (downlink TCI state) and the seventh TCI state (uplink TCI state) ) is the paired TCI state, and the eighth TCI state (downlink TCI state) and the ninth TCI state (uplink TCI state) are the paired TCI state.
