Background

Currently, no relevant mechanism for antenna panel (panel) activation status is standardized in the 5G New air interface (NR) protocol. Specifically, the base station does not know the number of panels that the terminal (also called user terminal, user) has, and does not know the activation state of the user panels, and simply considers that the panel corresponding to the user receiving or transmitting the relevant channel is always in the activation state.

According to the Rel-17 project, the third generation partnership project (3GPP) wishes to support fast panel switching during communication for users with multiple panels, thereby achieving the purpose of saving power. I.e., requiring the user to deactivate one or more antenna panels used for transmitting and receiving signals.

However, in the prior art, if after the terminal deactivates one or more antenna panels, the terminal still needs to transmit and receive signals using the transmit and receive beams of the currently deactivated antenna panel, and the terminal cannot normally transmit and receive signals.

Specifically, in order to ensure that a channel configured to be transmitted and received by using a deactivated panel can still be normally transmitted and received within a period of time from a time when a user panel is deactivated to a time when transmission and reception beam reconfiguration information of a base station becomes effective, a transmission and reception beam determining method after an antenna panel is deactivated is needed, and after a terminal deactivates one or more antenna panels, the base station and the terminal can determine an actual transmission and reception beam.

Detailed Description

As described above, according to the subject matter of Rel-17, 3GPP desires to support fast panel switching during communication for users with multiple panels, so as to achieve the purpose of saving power. I.e., requiring the user to deactivate one or more antenna panels used for transmitting and receiving signals.

Specifically, in a high-frequency band scenario, a base station and a user respectively transmit and receive wireless signals by using directional beams. Based on the NR protocol, the base station and the user determine the optimal transceiving beam through a beam training process, so that the transmission reliability of uplink and downlink signals is improved by using the optimal transceiving beam. In the beam training and reporting process, the terminal stores the downlink receiving beam corresponding to each reported downlink transmitting beam.

In the aspect of beam indication, for a downlink control channel PDCCH, a base station configures a TCI state for each CORESET through a high-level signaling, all PDCCHs related to the CORESET adopt a downlink transmission beam indicated by the TCI state to transmit, and after a user receives configuration information, the user determines a downlink receiving beam according to the stored corresponding relation of the transmitting and receiving beams. According to the NR protocol, when a user needs to receive with a directional beam, there is no case where the base station does not configure the TCI state for the CORESET.

For an uplink control channel PUCCH, a base station configures uplink transmission beams for each PUCCH resource through high-level signaling. After receiving the beam configuration information, the user can determine the uplink transmission beam of each PUCCH resource. When the base station does not configure the uplink transmission beam of the PUCCH resource, the user firstly determines a default TCI state, determines a downlink receiving beam according to the downlink transmission beam of the base station indicated by the default TCI state, and determines the uplink transmission beam according to the downlink receiving beam. The default TCI status is determined as follows:

if CORESET is configured on the current carrier, the default TCI state is the TCI state configured for the minimum CORESET ID by the base station;

if the core set is not configured on the current carrier, the default TCI state is the first TCI state activated for the PDSCH by the base station.

However, in the related art, if it is still necessary to transceive signals using the transceive beam of the currently deactivated antenna panel after the terminal deactivates one or more antenna panels, it is impossible to determine an actual transceive beam.

The inventor of the present invention finds, through research, that no standardization is performed on a related mechanism of a panel activation state in the current NR protocol, the base station does not know the number of panels possessed by the user, and does not know the activation state of the user panel, and only simply thinks that the panel corresponding to the channel related to the user receiving or sending is always in the activation state.

Specifically, according to the subject matter of Rel-17, 3GPP wants to support fast panel switching in the communication process for users with multiple panels, so as to achieve the purpose of saving power. First, when reporting beams, a user needs to report a panel corresponding to each reported beam to a base station at the same time. When the base station configures the transceiving beams of each channel, the configuration users adopt corresponding panel to receive or transmit simultaneously.

In order to keep the base station and the user consistent with understanding of the activation state of the panel, the user needs to report the activation state of the panel to the base station. After the base station receives an event that a panel is deactivated, the base station needs to send configuration information to indicate a user to send and receive the panel in an activated state for a channel for sending and receiving the deactivated panel.

In order to ensure that a channel configured to be transceived by using a deactivated panel can still be normally transceived within a period of time from a time when a user panel is deactivated to a time when transceiving beam reconfiguration information of a base station becomes effective, a transceiving beam determining method after an antenna panel is deactivated is needed, and after a terminal deactivates one or more antenna panels, the base station and the terminal can determine an actual transceiving beam.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 1, fig. 1 is a flowchart of a method for determining a transmit-receive beam after an antenna panel is deactivated in an embodiment of the present invention. The method for determining the transmit/receive beam after the antenna panel is deactivated may be used at a terminal side, and may include steps S11 to S11 to S13:

step S11: deactivating one or more antenna panels among the antenna panels for transceiving signals, wherein the deactivated antenna panels are marked as currently deactivated antenna panels, and the remaining antenna panels are marked as currently activated antenna panels;

step S12: sending antenna panel deactivation indication information to a base station so that the base station can know the currently activated antenna panel and the currently deactivated antenna panel;

step S13: and if the transceiving beam of the antenna panel which is deactivated currently needs to be adopted for transceiving signals, determining the actual transceiving beam of the PDCCH and/or the PUCCH which is/are transceived by the antenna panel which is deactivated currently according to the antenna panel which is activated currently.

In the specific implementation of step S11, if a terminal with multiple panels switches between panels during communication for power saving or other purposes, and one or more antenna panels can be deactivated, the deactivated antenna panel may be recorded as a currently deactivated antenna panel, and the remaining antenna panels may be recorded as currently activated antenna panels.

In a specific implementation, this step may be performed in a conventional deactivation manner, which is not limited in this embodiment of the present invention.

In a specific implementation of step S12, after determining the deactivated antenna panel, the terminal sends the antenna panel deactivation indication information to the base station, so that the base station can know which antenna panels the currently activated antenna panel and the currently deactivated antenna panel are respectively.

Further, the antenna panel deactivation indication information may include: indication information of a currently deactivated antenna panel, and/or indication information of a currently activated antenna panel.

In specific implementation, the base station can intuitively determine which antenna panels the currently activated antenna panel and the currently deactivated antenna panel are respectively by sending two kinds of indication information, namely indication information of the currently deactivated antenna panel and indication information of the currently activated antenna panel; it is also possible to send only one of the two types of indication information, and the base station needs to determine the other one by calculation after receiving, so that the base station determines visually which antenna panels the currently activated antenna panel and the currently deactivated antenna panel are respectively.

In a specific implementation of step S13, when the terminal needs to transmit and receive signals using the transceiving beam of the currently deactivated antenna panel, an actual transceiving beam of the PDCCH and/or PUCCH that is transmitted and received by the currently deactivated antenna panel after deactivation is determined according to at least the currently activated antenna panel.

Specifically, the original panel may still be used for transceiving, especially beams that have been sent out by the base station, from the moment when the user panel is deactivated to the moment when the transceiving beam reconfiguration information of the base station is validated.

In the embodiment of the present invention, for different transceiving beams, different manners may be adopted to determine the actual transceiving beams of the PDCCH and/or PUCCH that is/are transceived by the currently deactivated antenna panel after deactivation.

In a first specific implementation manner of the embodiment of the present invention, the transmit-receive beam of the currently deactivated antenna panel is a downlink receive beam for receiving a PDCCH.

Referring to fig. 2, fig. 2 is a flowchart of an embodiment of step S13 in fig. 1. The step of determining an actual transceiving beam of the PDCCH and/or PUCCH that is transceived by the currently deactivated antenna panel after deactivation according to at least the currently activated antenna panel may include steps S21 to S26, and each step is described below.

In step S21, all downlink reception beams configured to the currently activated antenna panel of the PDCCH are determined.

In step S22, all downlink transmission beams corresponding to all downlink reception beams are determined, wherein each downlink transmission beam corresponds to one downlink reception beam.

Specifically, a plurality of downlink transmission beams may correspond to one downlink reception beam, or the downlink transmission beams may correspond to the downlink reception beams one to one.

In step S23, TCI states indicating all downlink transmission beams are determined and recorded as valid TCI states, where each TCI state is used to indicate one downlink transmission beam.

In other words, the condition of the valid TCI state means that the downlink receiving beam corresponding to the downlink transmitting beam of the base station indicated by the condition corresponds to a currently activated panel.

In step S24, valid CORESET is determined according to the valid TCI states, where each of the valid CORESET corresponds to one of the valid TCI states.

In step S25, the CORESET with the smallest CORESET ID among the valid CORESETs is determined.

In step S26, a downlink receive beam is determined from the downlink transmit beam indicated by the TCI status corresponding to the CORESET with the smallest CORESET ID, and is used as the actual transmit/receive beam.

In other words, in the method for determining a transceiving beam after the antenna panel is deactivated shown in fig. 2, the default TCI state is the TCI state with the smallest CORESET ID in the valid TCI states configured for CORESET by the base station.

In the embodiment of the present invention, when determining, according to the currently activated antenna panel, actual transmit/receive beams of the PDCCH and/or PUCCH that are transmitted/received by the currently deactivated antenna panel after deactivation, by gradually determining all downlink receive beams, all downlink transmit beams, an effective TCI state, and an effective CORESET that the currently activated antenna panel is configured to the PDCCH, a downlink receive beam may be determined according to a downlink transmit beam indicated by the TCI state corresponding to the CORESET having the smallest CORESET ID, thereby achieving determination of the actual transmit/receive beams.

In a second specific implementation manner of the embodiment of the present invention, the transmit-receive beam of the currently deactivated antenna panel is an uplink transmit beam used for transmitting a PUCCH.

Referring to fig. 3, fig. 3 is a flowchart of another embodiment of step S13 in fig. 1. The step of determining an actual transceiving beam of the PDCCH and/or PUCCH that is transceived by the currently deactivated antenna panel after deactivation according to at least the currently activated antenna panel may include steps S31 to S33, and each step is described below.

In step S31, all uplink transmission beams of the currently activated antenna panel configured to the PUCCH are determined.

In step S32, a PUCCH resource associated with each uplink transmission beam is determined, where each PUCCH resource is associated with one uplink transmission beam.

Specifically, multiple PUCCH resources may be configured with the same uplink transmission beam, and the PUCCH resources may correspond to the uplink transmission beams one to one.

In step S33, the uplink transmission beam corresponding to the PUCCH resource with the smallest PUCCH resource ID is determined as the actual transmission/reception beam.

In other words, in the method for determining a transceiving beam after the antenna panel is deactivated shown in fig. 3, the default uplink transmission beam refers to the uplink transmission beam which corresponds to the currently activated panel and is configured to the PUCCH with the minimum associated PUCCH resource ID.

In this embodiment of the present invention, when the currently deactivated transmit/receive beam of the antenna panel is an uplink transmit beam used for transmitting a PUCCH, the uplink transmit beam with the smallest PUCCH resource ID may be determined by determining the PUCCH resource ID of each uplink transmit beam, so as to determine an actual transmit/receive beam.

In a third specific implementation manner of the embodiment of the present invention, the transmit-receive beam of the currently deactivated antenna panel may be an uplink transmit beam used for transmitting a PUCCH.

Referring to fig. 4, fig. 4 is a flowchart of another embodiment of step S13 in fig. 1.

The step of determining an actual transceiving beam of the PDCCH and/or PUCCH that is transceived by the currently deactivated antenna panel after deactivation according to at least the currently activated antenna panel may include steps S41 to S44, and each step is described below.

In step S41, a downlink reception beam set of the currently activated antenna panel is determined, where the downlink reception beam set includes all downlink reception beam set beams that can be used for receiving the PDCCH and the PDSCH.

Specifically, the TCI status of PDCCH and PDSCH may be different, where all TCI statuses may be included into the downlink receive beam set.

In step S42, a downlink transmit beam set is determined according to the downlink receive beam set, where each downlink transmit beam in the downlink transmit beam set corresponds to one downlink receive beam in one downlink receive beam set.

In step S43, a TCI status for indicating the downlink transmission beam set is determined and recorded as a valid TCI status, where each TCI status is used to indicate one downlink transmission beam in the downlink transmission beam set.

In step S44, the actual transceiving beam is determined according to the valid TCI status.

It should be noted that the actual transceiving beams may be determined in different manners according to whether the CORESET is configured on the current carrier.

Further, in a case that a CORESET is configured on a current carrier, the step of determining the actual transceiving beam according to the effective TCI state may include: determining valid CORESETs according to the valid TCI states, wherein each of the valid CORESETs corresponds to one of the valid TCI states; determining the CORESET with the smallest CORESET ID in the valid CORESETs; determining a downlink receiving beam according to the downlink transmitting beam indicated by the TCI state corresponding to the CORESET with the minimum CORESET ID; and determining an uplink transmitting beam according to the downlink receiving beam and taking the uplink transmitting beam as the actual transceiving beam.

Further, in a case that no CORESET is configured on the current carrier, the step of determining the actual transceiving beam according to the effective TCI state may include: in the effective TCI state, determining the TCI state with the smallest TCI state ID activated by the base station for the PDSCH; determining a downlink receiving beam according to the downlink transmitting beam indicated by the TCI state with the minimum TCI state ID; and determining an uplink transmitting beam according to the downlink receiving beam, and taking the uplink transmitting beam as the actual transceiving beam.

In other words, in the method for determining a transceiving beam after the antenna panel is deactivated shown in fig. 4, the user first determines a default TCI status, determines a downlink receiving beam according to the downlink transmitting beam of the base station indicated by the default TCI status, and determines a default uplink transmitting beam according to the downlink receiving beam.

Specifically, if the core set is configured on the current carrier, the default TCI state is the TCI state with the minimum core set ID in the valid TCI states configured for the core set by the base station; if no CORESET is configured on the current carrier, the default TCI state is the first valid TCI state activated for the PDSCH by the base station.

In the embodiment of the present invention, when the currently deactivated transmit/receive beam of the antenna panel is an uplink transmit beam used for transmitting a PUCCH, a downlink transmit beam set and an effective TCI state may be determined, and then a downlink receive beam is determined in different manners according to whether a CORESET is configured on a current carrier used for transmitting the PUCCH, thereby achieving determination of an actual transmit/receive beam.

Referring to fig. 5, fig. 5 is a flowchart of another method for determining a transmit/receive beam after an antenna panel is deactivated in an embodiment of the present invention. The another method for determining a transmission/reception beam after deactivation of an antenna panel may be applied to a base station, and may further include steps S51 to S53:

step S51: receiving antenna panel deactivation indication information from a terminal, wherein the antenna panel deactivation indication information is determined after one or more antenna panels are deactivated by the terminal in antenna panels used for transmitting and receiving signals, the deactivated antenna panels are marked as currently deactivated antenna panels, and the rest antenna panels are marked as currently activated antenna panels;

step S52: acquiring the currently activated antenna panel and the currently deactivated antenna panel according to the antenna panel deactivation indication information;
