The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the specification. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Fig. 1 is a schematic view of a scenario of a communication system according to an embodiment of the present invention. The communication system 100 may be a wireless communication system, which may operate in a licensed frequency band or an unlicensed frequency band. It can be understood that the use of the unlicensed frequency band can improve the system capacity of the wireless communication system, improve the channel access efficiency, improve the spectrum resource utilization rate, and finally improve the system performance.

As shown in fig. 1, the communication system 100 may include at least one network device 101 and at least one terminal device 102, and the network device 101 is connected to the terminal device 102, the terminal device 102 and the terminal device 102, and the network device 101 through wired or wireless communication technologies. It should be noted that the number and form of the terminal devices 102 and the network devices 101 shown in fig. 1 do not limit the embodiment of the present invention. In various embodiments, network device 101 may also be connected to a core network device, which is not shown in fig. 1.

It should be noted that, the wireless communication systems according to the embodiments of the present invention include, but are not limited to: a narrowband Band-internet of Things (NB-IoT), a Global System for Mobile Communications (GSM) 100, an Enhanced Data Rate GSM Evolution (EDGE) System, a Wideband Code Division Multiple Access (WCDMA) System, a Code Division Multiple Access (Code Division Multiple Access, CDMA 2000) System, a time Division-synchronous Code Division Multiple Access (tds-CDMA) System, a Long term Evolution (Long term Evolution, LTE) System, a fifth generation Mobile communication System, a vehicle-mounted wireless short-range communication System, and a future Mobile communication System.

In this embodiment of the present invention, the network device 101 is a device deployed in a radio access network and providing a wireless communication function for the terminal device 102. The network device 101 may include, but is not limited to, a Base Station (BS), a Station (Station, STA including an Access Point (AP) and a non-AP Station STA), a network controller, a Transmission and Reception Point (TRP), a mobile switching center or a wireless Access Point in wifi, and the like, and for example, a device directly communicating with the terminal device 102 through a wireless channel is typically a Base Station. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, or Radio Remote Units (RRUs), etc. Of course, the network device 101 may perform wireless communication with the terminal device 102, and may also perform other wireless communication functions, which is not limited in this application.

The Terminal device 102 may include, for example, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., and is a device that provides voice and/or data connectivity communication to a User, such as a handheld device with wireless connectivity capability, a vehicle-mounted device, a wearable device, a computing device, or other processing device linked to a wireless modem. Currently, some examples of terminals are: a Mobile Phone (Mobile Phone), a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable Device, a Virtual Reality (VR) Device, an Augmented Reality (AR) Device, a wireless terminal in Industrial Control (Industrial Control), a wireless terminal in unmanned Driving (Self Driving), a wireless terminal in Remote Surgery (Remote Medical Surgery), a wireless terminal in Smart Grid, a wireless terminal in Transportation Safety, a wireless terminal in City (Smart City), a wireless terminal in Smart Home (Smart Home), and the like.

Note that the names of the devices may be different in different systems, for example, in an LTE network, the base station is called an Evolved Node B (eNB or eNodeB), in a third generation (3G) network, the base station is called a Node B (Node B), and in a 5G network, the base station is called a 5G base station (NR Node B, gNB).

When the terminal device moves from the coverage of the current cell to the coverage of the target cell, the communication quality is poor because the terminal device continues to access the current cell, and therefore the cell accessed by the terminal device needs to be switched to the target cell.

In the embodiment of the invention, the terminal equipment can activate the TCI state in the TCI state pool according to the cell switching instruction and determine the receiving and transmitting wave beam in the target cell by adding the first information in the cell switching instruction, thereby completing the process of cell switching. Therefore, the resource overhead and effective time delay of the terminal equipment in the cell switching process are reduced.

Fig. 2 is a flowchart of a TCI status activation method according to an embodiment of the present invention, and as shown in fig. 2, the method includes:

step 201, a network device sends a cell switching instruction to a terminal device, where the cell switching instruction includes first information used to determine a state of a TCI to be activated. The network device may be a base station device or a switch. The network device may determine whether the terminal device needs to perform cell handover according to information such as the positioning or communication quality of the terminal device. For example, when the network device determines that the terminal device moves from the coverage of the cell a to the coverage of the cell B according to the positioning information of the terminal device, it may determine that the cell accessed by the terminal device needs to be switched. Optionally, when the network device detects that the communication quality with the terminal device is poor, the cell accessed by the terminal device may be switched to another cell with good communication quality.

In some embodiments, the cell switching instruction may be implemented as a Media Access Control (MAC CE) Element message or a Downlink Control Information (DCI) message. The first information may be a TCI status index, a reference signal resource index, a serving cell index of the target cell, or a physical cell index. Since the MAC CE message or the DCI message is a message for instructing the terminal device to perform cell handover, and is not a message specifically for instructing the terminal device how to activate the TCI state in the TCI state pool, several fields in the MAC CE message or the DCI message may be used to represent the first information. For example, when the first information in the MAC CE message or the DCI message is a 3-bit field, the first information may be 8 different values, and each value corresponds to a specific index.

Step 202, the terminal device receives a cell switching instruction sent by the network device, where the cell switching instruction includes first information used for determining a to-be-activated TCI state.

In some embodiments, if the first information is a TCI status index, the terminal device may determine, from the TCI status pool, a TCI status to be activated according to an indication of the TCI status index. Alternatively, the TCI state index may be implemented in the form of a bitmap or a TCI state ID. And if the TCI state index is bitmap, the terminal equipment determines the TCI state corresponding to the bit position with the bitmap value of '1' (or '0') in the TCI state pool as the TCI state to be activated. Wherein, the TCI status pool is determined according to the pre-configuration information sent by the network equipment. Specifically, before performing cell handover, the network device sends provisioning information to the terminal device in the form of a Radio Resource Control (RRC) message, and the terminal device configures a TCI state pool including a plurality of TCI states according to the provisioning information.

And if the TCI state index is the TCI state ID, the terminal equipment determines the TCI state containing the TCI state ID indicated by the network equipment in the TCI state pool as the TCI state to be activated. For example, 11 TCI states with TCI state IDs of 0 to 10 are included in the TCI state pool, and the TCI state IDs included in the first information are 0, 2, and 5, then the TCI states with TCI state IDs of 0, 2, and 5 in the TCI state pool are determined as the TCI states to be activated.

In some embodiments, if the first information is a reference signal resource index, the terminal device determines a to-be-activated TCI state from a TCI state pool according to the reference signal resource index, where the to-be-activated TCI state includes the reference signal resource index. For example, the reference signal resources corresponding to each TCI state in the TCI state pool are a, b, and c, respectively. The reference signal resource index included in the first information is an index of a. The terminal device determines the reference signal resource a as the target reference signal resource according to the first information, and then determines the TCI state in which the reference signal resource a in the TCI state pool is a as the TCI state to be activated.

In some embodiments, if the first information is the target cell index, the terminal device may determine, according to the first information, a TCI set from the TCI status pool, and then determine, from the TCI status set, a TCI status to be activated. Specifically, the terminal device may first determine a cell index of a transmission cell of the reference signal included in each TCI state in the TCI state pool. And then picking out TCI states with consistent cell indexes and target cell indexes to form a TCI state set. Since the terminal device may have undergone cell switching many times, the TCI states of multiple cells may exist in the TCI state pool of the terminal device, and therefore the terminal device may screen the TCI states corresponding to the target cell from the TCI state pool according to the cell index to form a TCI state set, and then determine the TCI state to be activated from the TCI state set.

The terminal device may determine a TCI state in which a TCI state index in the TCI state set satisfies a first preset condition as the to-be-activated TCI state. Optionally, the first preset condition may be that n TCI state indexes are minimum, n TCI state indexes are maximum, the TCI state index is odd, the TCI state index is even, and the like. The first preset condition may be implemented in a predefined or configured manner.

And 203, activating the to-be-activated TCI state determined according to the first information to obtain an activated TCI state.

In some embodiments, after activating the to-be-activated TCI state, the terminal device may determine the transceiving beam in the target cell according to the activated TCI state. If only 1 TCI state is active, the TCI state may be determined to be the target TCI state. Optionally, after receiving a downlink control instruction sent by the network device, the activated TCI state may be determined as the target TCI state according to the downlink control instruction. And then the terminal equipment determines the specific parameters of the transceiving beams adopted in the target cell according to the target TCI state.

In some embodiments, if multiple TCI states are activated, a target TCI state may be determined from a second message sent by the network device. As shown in fig. 3, the method comprises the following processing steps:

step 301, the network device sends a second message to the terminal device, where the second message includes second information used to determine the target TCI status.

In step 302, the terminal device receives a second message sent by the network device, where the second message includes second information used to determine the target TCI status.

And step 303, the terminal equipment determines a target TCI state from the activated TCI states according to the second information. For example, if the terminal device has both TCI states activated under the indication of the network device IDE, the network device may send a second message containing a TCI state ID or other information that may identify the TCI states to instruct the terminal device to determine one of the activated TCI states as the target TCI state.

In some embodiments, the terminal device may determine the target TCI state from the activated multiple TCI states according to a second preset condition, without the network device sending a downlink control instruction including the second information to the terminal device. Optionally, the second preset condition may be: and determining the TCI state with the smallest TCI state index in the activated TCI states as the target TCI state. For example, 4 TCI states are activated, and the indexes of the 4 TCI states are: 0. 1, 2, and 3, the TCI state with the smallest TCI state index may be determined as the target TCI state, i.e., the TCI state with index 0. The second preset condition may also be: and determining the TCI state with the largest TCI state index in the activated TCI states as the target TCI state.

After the terminal device determines the transceiving beam in the target cell, the terminal device and the network device can communicate based on the transceiving beam.

Corresponding to the above TCI state activation method, an embodiment of the present invention provides a terminal device, as shown in fig. 4, where the terminal device includes: a first communication module 401 and a first processing module 402.

The first communication module 401 is configured to receive a cell switching instruction sent by a network device, where the cell switching instruction includes first information used to determine a to-be-activated TCI state.

The first processing module 402 is configured to activate the TCI state to be activated determined according to the first information, so as to obtain an activated TCI state.
