Description

[Technical field]

[0001] The present invention relates to the field of communication technology, and in particular to a method, device, base station and storage medium for determining a default beam. [Background technology]

[0002] At present, in the standardization process of the 17th version (Rel-17) of the New Radio (NR) system, one of the ways to further enhance the Multiple-In Multiple-Out (MIMO) technology is to introduce a unified beam configuration framework (Unified TCI framework), which is used to simultaneously indicate that the uplink control channel, downlink control channel, and data channel in one or more carriers use the same direction of the transceiver beam. Under the unified beam configuration framework, the base station sends downlink control information (DCI) signaling to the user equipment (UE). Before the DCI signaling takes effect, the UE needs to decode the DCI signaling and obtain the transmission configuration indication (TCI) status. After the DCI signaling takes effect, the UE transmits and receives uplink signals and / or downlink signals according to the transceiver beam indicated by the TCI status.

[0003] Before the DCI signaling takes effect, if the UE has not determined the transmit and receive beams, if the UE needs to transmit and receive uplink signals and / or downlink signals, it is necessary to determine a default beam. However, the prior art does not define the selection of a default beam. Therefore, before the DCI signaling takes effect, the base station and the UE may use different beams to transmit and receive uplink signals and / or downlink signals, resulting in the uplink signals and / or downlink signals being unable to be successfully received, thereby reducing the communication quality. [Summary of the invention]

[0057] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0058] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0060] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0061] It should be understood that, although the terms first, second, etc. may be used to describe the set thresholds in the embodiments of the present invention, these set thresholds should not be limited to these terms. These terms are only used to distinguish the set thresholds from each other. For example, without departing from the scope of the embodiments of the present invention, the first set threshold may also be referred to as the second set threshold, and similarly, the second set threshold may also be referred to as the first set threshold.

[0062] Based on the 3GPP NR protocol, the base station and UE determine the optimal transmit and receive beams through beam training, and transmit and receive signals through the optimal transmit and receive beams, thereby improving the transmission reliability of uplink and / or downlink signals. In actual deployment environments, in order to further enhance MIMO technology, a unified beam configuration framework is introduced, which is used to simultaneously indicate that the uplink control channel, downlink control channel, and data channel in one or more carriers use the same direction of transmit and receive beams. Under the unified beam configuration framework, the base station first configures the UE. After the configuration is successful, the base station sends a multiple access channel control element (MAC Control Element, abbreviated as: MAC CE) signaling to the UE to activate the TCI state. After activation, a TCI state is indicated through the downlink control information (Downlink Control Information, abbreviated as: DCI) signaling. Before the DCI signaling takes effect, the UE needs to decode the DCI signaling and obtain the transmission configuration indication (transmission configuration indication, abbreviated as: TCI) state. After the DCI signaling takes effect, the uplink signal and / or downlink signal is received and sent according to the transceiver beam indicated by the TCI state.

[0063] Before the DCI signaling takes effect, if the UE has not determined the transceiver beam, the prior art does not define the selection of the default beam. If the UE needs to transmit and receive uplink signals and / or downlink signals at this time, the base station and the UE may use different beams to transmit and receive uplink signals and / or downlink signals, resulting in the uplink signals and / or downlink signals being unable to be successfully received, thereby reducing the communication quality. Therefore, it is necessary to provide a method for determining a default beam to ensure the communication quality between the base station and the UE before the DCI signaling takes effect.

[0065] Step 101: Configure user equipment through configuration information in first signaling, where the configuration information includes a state pool, and the state pool includes multiple transmission configuration indication states.

[0066] Step 102: In response to successful configuration of the user equipment, activate at least one transmission configuration indication state through a second signaling.

[0067] Step 103: Receive an activation confirmation message sent by the user equipment.

[0068] Step 104: Determine a default beam of the user equipment according to the second signaling.

[0069] In the technical solution provided by the embodiment of the present invention, the user equipment is configured through the configuration information in the first signaling, the configuration information includes a status pool, and the status pool includes multiple transmission configuration indication states; in response to the successful configuration of the user equipment, at least one transmission configuration indication state is activated through the second signaling; an activation confirmation message sent by the user equipment is received; according to the second signaling, the default beam of the user equipment is determined, which can improve the communication quality between the base station and the user equipment.

[0070] Figure 2 A flowchart of another method for determining a default beam provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, the method includes:

[0071] Step 201: Configure the UE through first configuration information in a first signaling, where the first signaling includes the first configuration information.

[0072] In the embodiment of the present invention, each step is executed by a base station.

[0073] In the embodiment of the present invention, the first signaling is a radio resource control (Radio Resource Control, RRC for short) signaling.

[0074] In an embodiment of the present invention, the first configuration information includes a first state pool and a first configuration rule. The first state pool includes multiple TCI states, and the first configuration rule includes configuring an uplink beam and a downlink beam with the same beam direction to transmit and receive uplink signals and downlink signals.

[0075] Step 202: In response to successful UE configuration, activate at least one TCI state through a second signaling.

[0076] In the embodiment of the present invention, the base station configures the UE according to the first configuration information, and after the UE is successfully configured, activates at least one TCI state through the second signaling. The second signaling includes the first activation information, and the first activation information includes at least one TCI state in the first state pool.

[0077] In the embodiment of the present invention, the second signaling is MAC CE signaling.

[0078] In the embodiment of the present invention, the base station may select at least one TCI state to be activated according to its own rules. For example, the base station may determine the first two TCI states in the first state pool as the TCI states to be activated.

[0079] Step 203: Receive an activation confirmation (ACK) message sent by the UE.

[0080] In the embodiment of the present invention, after receiving the MAC CE signaling, the UE sends an ACK message to the base station. The ACK message is used to indicate that the MAC CE signaling is received successfully and at least one TCI state indicated by the MAC CE signaling has been successfully activated.

[0081] Step 204: Determine a default beam of the user equipment according to the second signaling.

[0082] In the embodiment of the present invention, the default beam includes a default uplink beam and a default downlink beam.

[0083] As an optional scheme, according to the second signaling, the base station determines the downlink beam indicated by the first activated TCI state as the default downlink beam of the UE, so that the UE can use the beam to receive the corresponding downlink signal; the base station determines the uplink beam having the same direction as the downlink beam indicated by the first activated TCI state as the default uplink beam of the UE, so that the UE can use the beam to send uplink signals.

[0084] As another optional solution, before step 201, it also includes: the base station sends a synchronization signal block (SSB) to the UE within a specified period, and when the UE detects the SSB, it obtains the random access information carried by the SSB, and the UE performs random access according to the random access information; in response to the UE's successful random access, the UE performs RRC configuration and continues to execute step 201. The base station can determine the downlink beam corresponding to the SSB in the most recent random access process as the default downlink beam of the UE, so that the UE can use the beam to receive the corresponding downlink signal; the base station determines the uplink beam with the same direction as the downlink beam corresponding to the SSB as the default uplink beam of the UE, so that the UE can use the beam to send an uplink signal. Optionally, the specified period is 5 milliseconds (ms).

[0085] As another optional solution, the base station obtains the configuration information of multiple control resource sets (CORESETs) monitored by the UE in the most recent time slot, and the configuration information of the CORESET includes the identification code (ID) of the CORESET; the base station compares the IDs of multiple CORESETs, and determines the downlink beam corresponding to the CORESET with the smallest ID as the default downlink beam of the UE, so that the UE can use the beam to receive the corresponding downlink signal; the UE determines the uplink beam with the same direction as the downlink beam corresponding to the CORESET with the smallest ID as the default uplink beam, so that the UE can use the beam to send uplink signals. Among them, the UE can obtain the configuration information of the CORESET through RRC signaling.

[0086] In the embodiment of the present invention, it is necessary to determine the default beam of the UE so that the UE can communicate with the base station accurately and with high quality before the DCI signaling takes effect.

[0087] In the technical solution of the method for determining the default beam provided in an embodiment of the present invention, the user equipment is configured through the configuration information in the first signaling, the configuration information includes a status pool, and the status pool includes multiple transmission configuration indication states; in response to successful configuration of the user equipment, at least one transmission configuration indication state is activated through the second signaling; an activation confirmation message sent by the user equipment is received; and according to the second signaling, the default beam of the user equipment is determined, which can improve the communication quality between the base station and the user equipment.

[0088] Figure 3 A flowchart of another method for determining a default beam provided by an embodiment of the present invention is shown in FIG. Figure 3 As shown, the method includes:

[0089] Step 301: Configure the UE through second configuration information in the first signaling, wherein the first signaling includes the second configuration information.

[0090] In the embodiment of the present invention, each step is executed by a base station.

[0091] In the embodiment of the present invention, the first signaling is RRC signaling.

[0092] In an embodiment of the present invention, the second configuration information includes a second state pool, a third state pool, and a second configuration rule. The second state pool includes multiple downlink transmission configuration indication (DL TCI) states, the third state pool includes multiple uplink transmission configuration indications (UL TCI), and the second configuration rule includes configuring uplink beams and downlink beams with different beam directions to transmit and receive uplink signals and downlink signals.

[0093] Step 302: In response to successful UE configuration, activate at least one DL TCI state and UL TCI state through second signaling.

[0094] In an embodiment of the present invention, the base station configures the UE according to the second configuration information, and after the UE is successfully configured, activates at least one DL TCI state and UL TCI state through the second signaling. The second signaling includes the second activation information, and the second activation information includes at least one DL TCI state in the second state pool and at least one UL TCI in the third state pool.

[0095] In the embodiment of the present invention, the second signaling is MAC CE signaling.

[0096] In the embodiment of the present invention, the base station may select at least one DL TCI state and at least one UL TCI to be activated according to its own rules. For example, the base station may determine the first two DL TCI states in the second state pool as the DL TCI states to be activated, and may also determine the first three UL TCI states in the third state pool as the UL TCI states to be activated.

[0097] Step 303: Receive an ACK message sent by the UE.

[0098] In the embodiment of the present invention, after receiving the MAC CE signaling, the UE sends an ACK message to the base station. The ACK message is used to indicate that the MAC CE signaling is received successfully and at least one DL TCI state and UL TCI state indicated by the MAC CE signaling has been successfully activated.

[0099] Step 304: Indicate the specified TCI state to the UE through a third signaling.

[0100] In the embodiment of the present invention, the third signaling is DCI signaling.

[0101] In an embodiment of the present invention, a base station sends DCI signaling to a UE, and the DCI signaling includes a DL TCI state or a UL TCI state, so that the UE can decode the DCI signaling and obtain the indicated DL TCI state or UL TCI state. After the DCI signaling takes effect, the UE transmits and receives uplink signals and / or downlink signals according to the transmit and receive beams indicated by the DL TCI state or the UL TCI state.

[0102] Step 305 , determine whether the designated TCI state is a DL TCI state or a UL TCI state. If it is a DL TCI state, execute step 306 ; if it is a UL TCI state, execute step 307 .

[0103] In this embodiment of the present invention, if it is determined that the specified TCI state is the DL TCI state, it indicates that the base station indicates the DLTCI state to the UE, and step 306 is continued; if it is determined that the specified TCI state is the UL TCI state, it indicates that the base station indicates the UL TCI state, and step 307 is continued.

[0104] Step 306: Determine the default downlink beam of the UE.

[0105] As an optional solution, the base station determines the downlink beam used to send the third signaling as the default downlink beam of the UE, so that the UE can use the beam to receive the corresponding downlink signal.

[0106] As another optional solution, according to the second signaling, the base station determines the downlink beam indicated by the first activated DL TCI state as the default downlink beam of the UE, so that the UE can use the beam to receive the corresponding downlink signal.

[0107] As another optional solution, before step 201, it also includes: the base station sends an SSB to the UE within a specified period, and when the UE detects the SSB, it obtains the random access information carried by the SSB, and the UE performs random access according to the random access information; in response to the UE's random access success, the UE performs RRC configuration and continues to perform step 201. The base station can determine the downlink beam corresponding to the SSB in the most recent random access process as the default downlink beam of the UE, so that the UE can use the beam to receive the corresponding downlink signal. Optionally, the specified period is 5ms.

[0108] As another optional solution, the base station obtains the configuration information of multiple CORESETs monitored by the UE in the most recent time slot, and the configuration information of the CORESET includes the ID of the CORESET; the base station compares the IDs of the multiple CORESETs, and determines the downlink beam corresponding to the CORESET with the smallest ID as the default downlink beam of the UE, so that the UE can use the beam to receive the corresponding downlink signal.

[0110] Step 307: Determine the default uplink beam.

[0111] As an optional solution, the base station determines the uplink beam used to send the ACK message as the default uplink beam of the UE, so that the UE can use the default uplink beam to send uplink signals. The ACK message is a confirmation message that the user equipment successfully receives the second signaling.

[0112] As another optional solution, according to the second signaling, the base station determines the uplink beam indicated by the first activated UL TCI state as the default uplink beam of the UE, so that the UE can use the default uplink beam to send uplink signals.
