Description

Technical Field

[0001] (Cross - reference to related applications) The present invention claims the priority of a Chinese patent application with an application number of 202011055108.2 and an invention title of "Communication Resource Activation Method, Terminal, and Network - side Device", which was filed with the Chinese Patent Office on September 29, 2020. All of the content of this application is incorporated herein by reference into the present invention.

[0002] This application belongs to the field of wireless communication technology, and specifically relates to a communication resource activation method, a terminal, and a network - side device.

Background Art

[0003] In related technologies, the network - side device activates the secondary cell of a terminal (which may also be referred to as a terminal device or a user equipment (UE)), and can communicate on the secondary cell after a specified time, including triggering the UE to transmit a sounding reference signal (SRS). For example, the network - side device can activate secondary cells 1 to 7 respectively through bits C1 to C7 in the medium access control (MAC) control unit (CE) signaling. When a certain bit is 1, it indicates that the corresponding secondary cell has been activated.

[0004] Also, when a certain bandwidth part (BWP) of the UE is in a sleep state, the network - side device can activate this BWP and communicate on this BWP after a specified time, including triggering the UE to transmit SRS. For example, the network - side device may activate the BWP in the sleep state through a downlink control information (DCI) command.

[0005] As can be seen, in the related art, since the network-side device needs a certain amount of time to communicate on the secondary cell or BWP after activating the secondary cell or BWP, a long time is also required to complete the uplink and downlink beam scanning on the BWP activated by the secondary cell. That is, a long time is required for the secondary cell or BWP from activation to normal communication.

It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0022] In the following, the method for activating communication resources according to the embodiments of the present application will be described in detail by way of specific embodiments and their application scenarios while referring to the drawings.

[0023] FIG. 2 shows a flowchart of a method for activating communication resources in an embodiment of the present application. This method 200 may be executed by a network-side device. In other words, the method may be executed by software or hardware installed in the network-side device. As shown in FIG. 2, this method may include the following steps.

[0024] S210. The network-side device activates the target communication resources of the terminal, where the target communication resources include a secondary cell or a BWP in the sleep state.

[0025] In the embodiments of the present application, the network-side device may activate the target communication resources of the terminal via activation signaling. For example, the target communication resources of the terminal are activated via a MAC CE command or a DCI command.

[0026] In the embodiments of the present application, the secondary cell of the terminal may be a secondary carrier of the terminal.

[0027] S212. When activating the target communication resources, the network-side device performs uplink beam scanning on the target communication resources at the same time.

[0028] In the embodiments of the present application, when activating the target communication resources, the network-side device performs uplink beam scanning on this target communication resources at the same time. For example, after sending the activation signaling for activating the target communication resources, the network-side device may start uplink beam scanning before receiving the confirmation signaling for this activation signaling of the terminal.

[0029] According to the technical solution of the embodiment of the present application, the network-side device activates the target communication resource of the terminal, and at the same time when activating the target communication resource, performs uplink beam scanning on the target communication resource, where the target communication resource includes a secondary cell or a BWP in a sleep state. Thereby, the activation time and beam scanning time of the target communication resource can be shortened, the time from the activation of the target communication resource to normal communication can be shortened, and the activation efficiency of the target communication resource can be improved.

[0030] FIG. 3 shows another flowchart of the communication resource activation method in the embodiment of the present application, and this method 300 may be executed by a network-side device. In other words, the method may be executed by software or hardware installed in the network-side device. In method 300, the communication resource is a secondary cell of the UE. As shown in FIG. 3, this method may include the following steps.

[0031] S310, the network-side device activates the secondary cell of the terminal.

[0032] S312, the network-side device performs uplink beam scanning on the secondary cell at the same time when activating the secondary cell.

[0033] In one possible implementation manner, the network-side device may activate the secondary cell via MAC CE signaling.

[0034] In the related art, after the secondary cell is activated, the network-side device arranges periodic SRS, semi-persistent SRS, or aperiodic SRS on the secondary cell, and also arranges some parameters to control the behavior of the terminal to specifically transmit SRS. Here, the related parameters of the semi-persistent SRS are arranged by upper-layer signaling (for example, Radio Resource Control (RRC) signaling). After a specified time after the MAC CE signaling activates the secondary cell, the terminal can start transmitting the semi-persistent SRS according to the related parameters of the SRS arranged by the RRC until the terminal receives the deactivation command from the base station. The related parameters of the aperiodic SRS are arranged by the RRC and triggered in the Downlink Control Information (DCI) for the terminal to transmit an SRS once. The RRC configuration parameters include time-domain parameters such as the SRS resource symbol position, the number of occupied symbols, frequency hopping, and the repetition parameter R. Therefore, in the related art, the time from when the network-side device activates the secondary cell to when it receives the SRS is long.

[0035] Therefore, in the above possible implementation manner, optionally, the MAC CE signaling for activating the secondary cell is further used to trigger the terminal to transmit the target SRS on the secondary cell. With this selective implementation manner, at the same time as activating the secondary cell, the terminal is triggered to transmit the target SRS on this secondary cell, which can shorten the time from when the network-side device activates the secondary cell to when it receives the target SRS. Furthermore, the network-side device can scan the uplink beam more quickly and shorten the time from when the secondary cell is activated to when the secondary cell is actually used.

[0036] In one possible implementation, the network-side device may pre-configure N candidate states of the SRS, each candidate state corresponding to at least one configuration parameter of the target SRS, and the MAC CE signaling may trigger one target state among the N candidate states of the target SRS while activating the secondary cell. For example, if the MAC CE signaling has a 2-bit indication field for indicating the state of the target SRS to be triggered, this target SRS may have four candidate state values, namely 00, 01, 10, and 11. In the pre-configuration, these four candidate states may respectively correspond to different configuration parameters of the target SRS. For example, 00 represents that the offset value of SRS resource 1 is x, 01 represents that the offset value of SRS resource 1 is y, and 10 represents repeated transmission, etc. Of course, this is not limited thereto. In a specific application, one candidate state may correspond to multiple configuration parameters (i.e., a set of configuration parameters) of the target SRS, and in the embodiments of the present application, it is not specifically limited.

[0037] In the above possible implementation, after receiving the MAC CE command, the terminal activates the secondary cell and transmits the target SRS simultaneously when the activation of the secondary cell is completed. This target SRS may be a periodic SRS, an aperiodic SRS, or a semi-persistent SRS. For example, when the terminal receives the MAC CE signaling for activating the secondary cell and feeds back the corresponding acknowledgment signaling (ACK) to the network, at 3 ms, this secondary cell is actually activated. Simultaneously when the secondary cell is actually activated, the terminal transmits the target SRS based on the SRS trigger state indicated by the MAC CE signaling.

[0038] In another possible implementation, the MAC CE signaling may carry a time offset value at which the terminal transmits the target SRS. Here, this time offset value is an additional time offset value on top of a predetermined time delay (a time delay defined by the protocol, which may be, for example, 3 ms) after the ACK corresponding to the MAC CE signaling for activating the secondary cell is transmitted, and this time offset value may be the same or different for multiple secondary cells. After receiving this MAC CE command, the terminal transmits the target SRS when it reaches the predetermined time delay after feedback of the ACK plus this time offset value. Optionally, this time offset value may not be carried in the MAC CE signaling but may be pre - arranged by upper - layer signaling.

[0039] In a specific application, one SRS set may have more than one SRS resource, and each SRS resource may be arranged in a different time - domain resource, for example, in different symbols. Therefore, in one possible implementation, the MAC CE signaling for activating the secondary cell may simultaneously indicate whether to repeat, that is, the MAC CE signaling carries indication information indicating whether the target SRS repeats. For example, repetition ON or OFF. When repetition is ON, that is, when it is indicated that the target SRS repeats, the terminal may transmit the target SRS using the same transmission beam on each SRS resource in one SRS set. In contrast, when repetition is OFF, that is, when the indication information indicates that the target SRS does not repeat, the terminal transmits the target SRS using different transmission beams on each SRS resource within one SRS set.

[0040] In one possible implementation, for semi-persistent SRS or periodic SRS, the MAC CE signaling for activating the secondary cell may indicate a time window length, that is, the MAC CE signaling carries indication information for indicating the time window length, and the terminal is instructed to transmit the target SRS within a time window corresponding to the time window length, where the target SRS is a periodic SRS or a semi-persistent SRS. In this possible implementation, after the secondary cell is activated, the terminal transmits the target SRS within a time window corresponding to the time window length, and outside this time window, the target SRS is not transmitted. Also, in actual applications, the time window length may not be indicated by the MAC CE signaling and may be predefined or agreed upon, and in the embodiments of this application, it is not specifically limited.

[0041] In one possible implementation, the MAC CE signaling carries indication information for indicating the transmission power offset amount of the target SRS. In actual applications, the network-side device may separately indicate this transmission power offset value for each secondary cell, or the network-side device may determine the transmission power offset amount based on the average power gain difference of the carrier frequencies of each secondary cell, and in the embodiments of this application, it is not specifically limited.

[0042] In one possible implementation, the network-side device may also activate the secondary cell via MAC CE signaling and may also use DCI signaling to trigger the target SRS on the secondary cell, and this target SRS is a transmission of an aperiodic SRS or a semi-persistent SRS. Therefore, in this possible implementation, after activating the secondary cell via MAC CE signaling, this method may further include the network-side device triggering, via DCI signaling, the terminal to transmit the target SRS on the secondary cell.

[0043] For example, before receiving the confirmation signaling (ACK) corresponding to the MAC CE signaling, the network-side device may send the DCI signaling, or the network-side device may send the DCI signaling before reaching a predetermined time delay (e.g., 3 ms) after receiving the confirmation signaling. Thereby, the terminal can be pre-triggered to transmit an aperiodic SRS or a semi-persistent SRS on the secondary cell.

[0044] In a specific application, one SRS set may have more than one SRS resource, and each SRS resource may be arranged in a different time-domain resource, for example, in a different symbol. Therefore, in the above possible implementation manner, optionally, the DCI signaling may carry indication information, such as repetition ON or OFF, indicating whether the target SRS repeats. When repetition is ON, that is, when it is indicated that the target SRS repeats, the terminal may transmit the target SRS using the same transmission beam on each SRS resource in one SRS set. When repetition is OFF, that is, when the indication information indicates that the target SRS does not repeat, the terminal transmits the target SRS using different transmission beams on each SRS resource within one SRS set.

[0045] In the above possible implementation manners, optionally, the DCI signaling may further carry a time offset value at which the terminal transmits the target SRS. Here, this time offset value is an additional time offset value on top of a predetermined time delay (which may be a time delay defined by the protocol, for example, 3 ms) after an acknowledgement (ACK) corresponding to the MAC CE signaling for activating the secondary cell is transmitted. This time offset value may be the same or different for a plurality of secondary cells. After receiving this DCI command, the terminal transmits the target SRS when reaching the predetermined time delay after feedback of ACK + this time offset value. Optionally, this time offset value may not be carried in the DCI signaling and may be pre - arranged by upper layer signaling.

[0046] In the above possible implementation manners, optionally, the DCI signaling carries indication information for indicating a time window length, and the terminal is instructed to transmit the target SRS within a time window corresponding to this time window length. In this possible implementation manner, after the secondary cell is activated, the terminal transmits the target SRS within the time window corresponding to this time window length and does not transmit the target SRS outside this time window. Also, in actual applications, this time window length may not be indicated by the DCI signaling and may be predefined or agreed upon, and in the embodiments of this application, it is not specifically limited.

[0047] In the above possible implementation manners, optionally, the DCI signaling carries indication information for indicating the transmission power of the target SRS. The network - side device may determine the transmission power for transmitting the target SRS on the activated secondary cell with reference to a path loss reference signal, where the path loss reference signal may be a reference signal on another already - activated carrier.

[0048] In one possible implementation, the network-side device activates the secondary cell via RRC signaling, where the RRC signaling is used to configure the secondary cell. That is, in this possible implementation, the network-side device can configure the secondary cell (SCell) and activate the secondary cell simultaneously using RRC signaling without the need for additional MAC CE signaling to activate the secondary cell, thereby shortening the activation time of the secondary cell.

[0049] In the above possible method, when activating the secondary cell via RRC signaling, optionally, MAC CE signaling or DCI signaling may be used to trigger the UE to transmit the target SRS. For the specific method, reference can be made to the above related descriptions and will not be elaborated here.

[0050] FIG. 4 shows another flowchart of the communication resource activation method in the embodiment of the present application. This method 400 may be executed by a network-side device. In other words, the method may be executed by software or hardware installed in the network-side device. In method 400, the communication resource is the BWP in the sleep state of the UE. As shown in FIG. 4, this method may include the following steps.

[0051] S410, The network-side device activates the BWP in the sleep state of the terminal.

[0052] S412, When activating the BWP, the network-side device performs uplink beam scanning on the BWP.

[0053] In one possible implementation, the network-side device activates the BWP in the sleep state via DCI signaling. For example, the DCI signaling may carry an identifier of the activated BWP in the sleep state.

[0054] In one possible implementation, the DCI signaling is further used to trigger the terminal to transmit a target SRS on the BWP, where the target SRS is an aperiodic SRS or a semi-persistent SRS. With this possible implementation, while activating the BWP, the terminal can be triggered to transmit a target SRS on the BWP.

[0055] In a specific application, one SRS set has more than one SRS resource, and each SRS resource may be arranged in a different time-domain resource, such as a different symbol. Therefore, in the above possible implementation, optionally, the DCI signaling may carry indication information, such as repetition ON or OFF, indicating whether the target SRS repeats. When repetition is ON, that is, when it is indicated that the target SRS repeats, the terminal may transmit the target SRS using the same transmission beam on each SRS resource in one SRS set. When repetition is OFF, that is, when the indication information indicates that the target SRS does not repeat, the terminal transmits the target SRS using different transmission beams on each SRS resource within one SRS set.

[0056] In the above possible implementation manners, optionally, the DCI signaling may further carry a time offset value at which the terminal transmits the target SRS. Here, this time offset value is a time offset value added on top of a predetermined time delay (which may be a time delay specified by the protocol, for example, 3 ms) after the BWP activates ACK transmission corresponding to the DCI signaling. For multiple BWPs, this time offset value may be the same or different. After receiving this DCI command, the terminal transmits the target SRS when it reaches the predetermined time delay after feedback of ACK plus this time offset value. Optionally, this time offset value may not be carried in the DCI signaling and may be pre-configured by upper layer signaling.

[0057] In the above possible implementation manners, optionally, the DCI signaling carries indication information indicating a time window length, and the terminal is instructed to transmit the target SRS within the time window corresponding to the time window length. In this possible implementation manner, after the BWP is activated, the terminal transmits the target SRS within the time window corresponding to the time window length and does not transmit the target SRS outside this time window. Also, in actual applications, the time window length may not be indicated by the MAC CE signaling and may be pre-defined or agreed upon, and is not specifically limited in the embodiments of this application.

[0058] In the above possible implementation manners, optionally, the DCI signaling carries indication information indicating the transmission power of the target SRS. The network side device may determine the transmission power for transmitting the target SRS on the activated BWP with reference to a path loss reference signal, where the path loss reference signal may be a reference signal on another activated BWP.

[0059] According to the above embodiments, the time from when the BWP is activated to when it is actually used can be shortened. Also, when the BWP is activated, the UE can be triggered to transmit the target SRS at the same time, and the time from when the BWP is activated to when the uplink beam can be scanned can be shortened.

[0060] FIG. 5 shows another flowchart of the SRS transmission method in the embodiments of the present application. This method 500 may be executed by a terminal. In other words, the method may be executed by software or hardware installed in the terminal. As shown in FIG. 5, this method may include the following steps.

[0061] S510, the terminal receives target communication resource activation signaling.

[0062] Here, the target communication resource activation signaling is activation signaling for activating the target communication resource transmitted by the network-side device. For its specific implementation method, reference can be made to the relevant descriptions in Methods 200-400, and no further description will be given here.

[0063] S512, when the activation of the target communication resource indicated by the target communication resource activation signaling is completed, the terminal transmits the target SRS on the target communication resource. Here, the target communication resource includes the secondary cell of the terminal or the BWP in the sleep state.

[0064] As described in the above Method 300, when the target communication resource is the secondary cell of the terminal, the target communication resource activation signaling may include MAC CE signaling for activating the secondary cell of the terminal.

[0065] As described in Method 300, the MAC CE signaling may trigger the terminal to transmit target SRS on the secondary cell where the terminal is activated, or may trigger the terminal to transmit target SRS on the secondary cell where the terminal is activated by DCI signaling. In the following, these two cases will be described respectively.

[0066] (1) The MAC CE signaling is further used to trigger the terminal to transmit target SRS on the secondary cell where the terminal is activated.

[0067] In one possible implementation, the MAC CE signaling triggers one of the N states simultaneously when activating the secondary cell, where the N states are N states pre - arranged for the target SRS, each state corresponding to at least one configuration parameter of the target SRS, and N is an integer greater than or equal to 1. Based on this MAC CE, the terminal can determine one configuration parameter or a set of configuration parameters of the target SRS. For example, if there is a 2 - bit indication field in the MAC CE signaling to indicate the state of the target SRS to be triggered, this target SRS may have 4 candidate state values, namely 00, 01, 10, and 11. In advance in the configuration, these 4 candidate states may respectively correspond to different configuration parameters of the target SRS. For example, 00 represents that the offset value of SRS resource 1 is x, 01 represents that the offset value of SRS resource 1 is y, and 10 represents repeated transmission, etc. When the value of this indication field in the received MAC CE is 10, it indicates the repeated transmission of the target SRS.

[0068] Therefore, in this possible implementation manner, after completing the activation of the target communication resource indicated by the target communication resource activation signaling, the terminal transmitting the target SRS on the target communication resource is including transmitting the target SRS on the secondary cell based on the state triggered by the MAC CE command after a predetermined time delay after the terminal feeds back the confirmation signaling corresponding to the MAC CE signaling.

[0069] In another possible implementation manner, after completing the activation of the target communication resource indicated by the target communication resource activation signaling, the terminal transmitting the target SRS on the target communication resource is determining, by the terminal, a time offset value for transmitting the target SRS, where the time offset value is a time offset with respect to a target time, and the target time is the time when a predetermined time delay after feeding back the confirmation signaling corresponding to the MAC CE signaling arrives, and the time offset value is indicated by the MAC CE signaling or is arranged by a network-side device via upper-layer signaling, and the terminal transmitting the target SRS at the time indicated by the time offset value may be included.

[0070] In a specific application, one SRS set may have more than one SRS resource, and each SRS resource may be arranged in different time domain resources, for example, different symbols. Therefore, transmitting the target SRS may include that when the MAC CE signaling instructs that the target SRS is repeated, the terminal transmits the target SRS on each SRS resource by adopting the same transmission beam, or when the MAC CE signaling instructs that the target SRS is not repeated, the terminal transmits the target SRS by adopting different transmission beams for different SRS resources. For example, when this indication information instructs that the target SRS is repeated, the terminal may transmit the target SRS using the same transmission beam on each SRS resource in one SRS set. When the indication information indicates that the target SRS is not repeated, the terminal transmits the target SRS using different transmission beams on each SRS resource in the SRS set.

[0071] In one possible implementation manner, transmitting the target SRS may include that the terminal transmits the target SRS within a time window corresponding to the time window length, where the time window length is indicated by the MAC CE signaling or is predefined. That is, in this possible implementation manner, after the secondary cell is activated, the terminal transmits the target SRS within the time window corresponding to the time window length and does not transmit the target SRS outside this time window. Here, the starting point of the time window may be the transmission time for feeding back the acknowledgment signaling (ACK) of the MAC CE, or may be the time at a predetermined time delay after feeding back the acknowledgment signaling (ACK) of the MAC CE. In the embodiments of this application, it is not specifically limited.

[0072] In one possible implementation manner, transmitting the target SRS includes the terminal transmitting the target SRS based on the transmission power offset amount indicated by the MAC CE signaling. In actual applications, the network-side device may separately indicate this transmission power offset value for each secondary cell, or the network-side device may determine the transmission power offset amount based on the average power gain difference of the carrier frequencies of each secondary cell, which is not specifically limited in the embodiments of this application.

[0073] (2) Trigger, via DCI signaling, the terminal to transmit the target SRS on the activated secondary cell In this implementation manner, when the terminal completes the activation of the target communication resource indicated by the target communication resource activation signaling, transmitting the target SRS on the target communication resource means receiving DCI signaling for triggering the terminal to transmit the target SRS on the secondary cell, where the target SRS is an aperiodic SRS or a semi-persistent SRS, and the DCI signaling is transmitted by the network-side device before receiving the confirmation signaling corresponding to the MAC CE signaling, or the DCI signaling is transmitted by the network-side device before a predetermined time delay arrives after receiving the confirmation signaling, and transmitting the target SRS according to the DCI signaling.

[0074] In a specific application, one SRS set may have more than one SRS resource, and each SRS resource may be arranged in different time domain resources, for example, in different symbols. Therefore, in one possible implementation, transmitting the target SRS may include that when the DCI signaling indicates that the target SRS repeats, the terminal transmits the target SRS on each SRS resource by adopting the same transmission beam, or when the DCI signaling indicates that the target SRS does not repeat, the terminal transmits the target SRS by adopting different transmission beams on different SRS resources. That is, in this possible implementation, the DCI signaling may carry indication information, such as repetition ON or OFF, indicating whether the target SRS repeats. When repetition is ON, that is, when it is indicated that the target SRS repeats, the terminal may transmit the target SRS using the same transmission beam on each SRS resource in one SRS set. When repetition is OFF, that is, when the indication information indicates that the target SRS does not repeat, the terminal transmits the target SRS using different transmission beams on each SRS resource within one SRS set.

[0075] In one possible implementation, when the terminal completes the activation of the target communication resource indicated by the target communication resource activation signaling, and simultaneously transmits a target SRS on the target communication resource, it is to determine a time offset value for the terminal to transmit the target SRS, where the time offset value is a time offset relative to a target time, and the target time is a predetermined time delay after feedback of an acknowledgment signaling corresponding to the target communication resource signaling. The time offset value is indicated by the DCI signaling or is configured by the network-side device via upper-layer signaling. The terminal transmits the target SRS at the time indicated by the time offset value. Here, this time offset value is an additional time offset value on top of a predetermined time delay (which may be a time delay specified by the protocol, for example, 3 ms) after an ACK corresponding to the MAC CE signaling for activating the secondary cell is transmitted. This time offset value may be the same or different for multiple secondary cells. After receiving this DCI command, the terminal transmits the target SRS when it reaches the predetermined time delay after ACK feedback + this time offset value.

[0076] In one possible implementation, transmitting the target SRS includes the terminal transmitting the target SRS within a time window corresponding to a time window length, where the time window length is indicated by the DCI signaling or is predefined. In this possible implementation, after the secondary cell is activated, the terminal transmits the target SRS within the time window corresponding to the time window length and does not transmit the target SRS outside this time window.

[0077] In one possible implementation, optionally, the DCI signaling carries indication information for indicating the transmission power of the target SRS. Therefore, transmitting the target SRS may include transmitting the target SRS based on the transmission power indicated by the DCI signaling by the terminal.

[0078] When the target communication resource is a BWP in a sleep state, in one possible implementation, the target communication resource activation signaling includes DCI signaling for activating the BWP in the sleep state.

[0079] In one possible implementation, the DCI signaling is further used to trigger the terminal to transmit the target SRS on the BWP.

[0080] In a specific application, when the terminal transmits the target SRS, an implementation corresponding to triggering the terminal to transmit the target SRS on the activated secondary cell via the above DCI signaling may be adopted. Specifically, reference may be made to the above related description of triggering the terminal to transmit the target SRS on the activated secondary cell via the DCI signaling, which will not be further described here.

[0107] In one possible implementation manner, for the transmission module 703 to transmit the target SRS, when the MAC CE signaling indicates that the target SRS is repeated, it includes transmitting the target SRS on each SRS resource by adopting the same transmission beam, or when the MAC CE signaling indicates that the target SRS is not repeated, it includes transmitting the target SRS by adopting different transmission beams on different SRS resources.

[0108] In one possible implementation manner, for the transmission module 703 to transmit the target SRS, it includes the terminal transmitting the target SRS based on the transmission power offset amount indicated by the MAC CE signaling.
