[0001] Cross-reference to Related Applications

[0002] This application claims priority to Chinese Patent Application No. 202010367082.9, filed on April 30, 2020, the contents of which are incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, and in particular to a downlink reception triggering method, a terminal and a network side device. BACKGROUND

[0004] In a mobile communication system, the conventional transmission mode is a scheduling-based transmission mode, for example, a terminal first acquires the time-frequency domain resources for its own downlink reception allocated by a network side device by listening to a physical downlink control channel (PDCCH), and then performs downlink reception on the corresponding resources.

[0005] In actual application scenarios, the scheduling-based transmission mode is not necessarily the most efficient. Taking extended reality (XR) as an example, XR refers to a combined environment of reality and virtuality and human-computer interaction generated by computer technology and wearable devices. In the XR application scenario, the data resources required by the user can be predicted according to the user's actions. However, the flexibility of the terminal to perform downlink reception according to dynamic scheduling by the network side device is poor and the efficiency is low, which cannot well meet the service requirements of the XR terminal and is not suitable for the XR service model.

[0040] Embodiments of the present application are described below with reference to the accompanying drawings. The embodiments provided by the present application can be applied to a wireless communication system. The wireless communication system can be a 5G system, or an evolved long term evolution (eLTE) system, or a subsequent evolved communication system.

[0041] Fig. 1 is a structural diagram of a network system provided by an embodiment of the present application, as shown in Fig. 1, which includes a terminal 11 and a network-side device 12, wherein the terminal 11 can be a mobile communication device, for example, a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, PDA), a mobile internet device (Mobile Internet Device, MID), or a wearable device, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

[0042] In order to more appropriately understand the technical solutions of the embodiments of the present application, before the technical solutions of the embodiments of the present application are described, the related technologies of the embodiments of the present application are introduced generally.

[0043] I. XR service

[0044] XR refers to all real and virtual combined environments and human-computer interactions generated by computer technology and wearable devices, which includes Augmented Reality (AR), Mediated Reality (MR), Virtual Reality (VR), and other representative forms, as well as the interpolation areas between them. The level of the virtual world ranges from partial sensory input to fully immersive virtual reality. One key aspect of XR is the extension of human experience, especially the experience related to presence (represented by VR) and cognitive acquisition (represented by AR).

[0045] In the application scenario of XR, the user can obtain information of a new visual angle in a virtual reality experience through head turning and other actions. At this time, the head turning action of the XR user can be sent to the network-side device through an uplink signal, and the network-side device will schedule the required downlink data for the XR user after receiving the uplink signal.

[0046] For XR (not excluding NR light) application scenarios, there will be a process triggered by uplink signals to trigger certain downlink reception. The existing technology does not support the mechanism of triggering downlink reception by uplink signals, which makes the resource consumption of the terminal large, and the flexibility of the terminal to perform downlink reception poor, and cannot well meet the service requirements of XR terminals, thereby cannot well meet the service requirements of XR users.

[0047] II. CDRX (Discontinuous Reception (DRX) in Radio Resource Control (RRC) connected state)

[0048] As shown in FIG. 2, the DRX cycle is composed of “On Duration” and “Opportunity for DRX”: in the time of “On Duration”, the terminal listens and receives PDCCH; in the time of “Opportunity for DRX”, the terminal does not listen to PDCCH to save power consumption. If a new PDCCH is received in onduration, an inactivity timer will be started or restarted to extend the time for the terminal to listen to PDCCH.

[0049] It should be noted that the “timer” involved in the present application can also be referred to as “timer”, that is, the meaning expressed by the “timer” involved in the present application is the same as or similar to the meaning expressed by the “timer”.

[0050] The system can configure the terminal with a short DRX cycle or a long DRX cycle according to different service scenarios. If both short and long cycles are configured, switching between the two long and short cycles can be performed in some way.

[0051] Therefore, the embodiment of the present application provides a method of triggering downlink reception by uplink signals, that is, the downlink reception triggering method provided by the embodiment of the present application.

[0052] FIG. 3 is a flowchart of the downlink reception triggering method provided by the embodiment of the present application. As shown in FIG. 3, the downlink reception triggering method is applied to a terminal, and the method comprises the following steps:

[0053] Step 201: a first uplink signal is sent, and the first uplink signal is used to trigger a first downlink reception.

[0054] In the embodiment of the present application, the terminal can directly trigger the first downlink reception by sending the first uplink signal, without the need for processes such as network side device configuring the first downlink reception, and therefore, triggering the first downlink reception by sending the first uplink signal is different from the existing downlink scheduling and downlink reception mode.

[0055] Triggering the first downlink reception by sending the first uplink signal is different from triggering the downlink reception in the existing scheduling transmission mode. In the existing scheduling transmission mode, for example, the terminal acquires the time-frequency domain resources of the downlink reception allocated by the network side device for itself by listening to the PDCCH, and then the terminal performs the downlink reception on the corresponding resources. In the embodiment of the present application, the terminal triggers the first downlink reception by sending the first uplink signal. The time-frequency domain resources of the first downlink reception and the configuration parameters such as the duration of the first downlink reception can be configured in advance by the network side device or carried by the first uplink signal, and the downlink reception can be triggered without the scheduling process. Therefore, triggering the first downlink reception by sending the first uplink signal can improve the flexibility and efficiency of the downlink reception.

[0056] The first uplink signal is used to trigger the first downlink reception, and it can be understood that there is an association relationship between the first uplink signal and the first downlink reception. After the terminal sends the first uplink signal, it can listen to or receive the first downlink reception according to the association relationship between the first uplink signal and the first downlink reception.

[0057] The association relationship between the first uplink signal and the first downlink reception may, for example, be an association relationship in terms of resource configuration parameters between the first uplink signal and the first downlink reception. Here, the resource configuration parameters may, for example, be time domain configuration parameters, frequency domain configuration parameters, or time-frequency domain configuration parameters, and the like.

[0058] In one embodiment, the first downlink reception is explicitly configured by the resource configuration parameters carried in the first uplink signal, and the network side device sends the first downlink reception according to the configuration parameters indicated by the received first uplink signal. For example, after the terminal sends the first uplink signal, it listens to the first downlink reception in a discontinuous reception manner. In addition, the first downlink reception can include multiple downlink receptions. In other words, the resource configuration parameters corresponding to the first downlink reception are different from the downlink reception resource configuration parameters configured by the network side device according to the RACH or BFR uplink signals sent by the terminal.

[0059] The association relationship between the first uplink signal and the first downlink reception can be established in advance, for example, the association relationship between the first uplink signal and the first downlink reception can be configured in advance by the network side device, or the association relationship between the first uplink signal and the first downlink reception can be agreed in advance by the protocol.

[0060] On the basis of the pre-established association between the first uplink signal and the first downlink reception, the first uplink signal is used to trigger the first downlink reception. It can be understood that the first uplink signal is used to activate the first downlink reception associated with the first uplink signal. More specifically, the first uplink signal is used to activate the first downlink reception under the corresponding resource configuration parameters.

[0061] The first downlink reception can include one or more (including two) downlink receptions. When the first downlink reception includes multiple downlink receptions, each downlink reception can correspond to a downlink reception type. When the first downlink reception includes one downlink reception, the downlink reception can correspond to a downlink reception type or not correspond to a specific type.

[0062] The first downlink reception can include at least one of downlink scheduling information reception, downlink signal reception, downlink data information reception, and downlink channel monitoring.

[0063] That is, the type of the first downlink reception can include at least one of downlink scheduling information, downlink signal, downlink data transmission information, and downlink channel monitoring. Among them, the downlink scheduling information can be, for example, a PDCCH, and downlink control information (DCI) in the PDCCH can be scrambled by a specific radio network temporary identifier, such as a cell radio network temporary identifier I (C-RNT) or a configurable scheduling RNTI (CS-RNTI). The DCI format of the PDCCH can be, for example, DCI 1-1, DCI 0-1, DCI 0-0, DCI 1-0, DCI 1-2, DCI 0-2, etc. The downlink signal can be, for example, a channel state information reference signal (CSI-RS), a CSI interference measurement (CSI-IM), a time reference signal (TRS), a phase-tracking reference signal (PTRS), a positioning reference signal (PRS), a synchronization signal block (SSB), etc. The downlink data transmission information can be, for example, a physical downlink shared channel (PDSCH) reception of semi-persistent scheduling (SPS). The downlink channel monitoring can be, for example, an unscheduled PDCCH, a group common PDCCH, etc. Other downlink channels or downlink signals are not excluded.

[0064] The type of the first uplink signal can include at least one of a type of an uplink channel and a signaling or signal type carried on the uplink channel. The type of the uplink channel can be a physical uplink control channel (PUCCH), a PUSCH (e.g., a PUSCH of a configured grant), a physical random access channel (PRACH) (e.g., Msg1, MsgA PRACH, MsgA PUSCH, Msg3). The periodicity of the uplink channel can be periodic, aperiodic, or semi-persistent. The signaling type or signal type carried on the uplink channel can be uplink control information (UCI), a scheduling request (SR), channel state information (CSI), a hybrid automatic repeat request (HARQ), a media access control (MAC) CE, a sounding reference signal (SRS), or the like. Other uplink channels or uplink signals are not excluded.

[0065] Optionally, the first uplink signal and the first downlink reception have a time-domain association relationship.

[0066] That is, when the association relationship between the first uplink signal and the first downlink reception includes a time-domain association relationship between the first uplink signal and the first downlink reception, the terminal can trigger the first downlink reception under the corresponding time-domain configuration parameter by sending the first uplink signal.

[0067] In the embodiments of the application, the first uplink signal can trigger the first downlink reception in an implicit indication manner, or the first uplink signal can trigger the first downlink reception in an explicit indication manner.

[0068] The following describes the implicit indication manner.

[0069] Optionally, the association relationship between the first uplink signal and the first downlink reception is configured by a network side device or agreed by a protocol.

[0070] In a case that the association relationship between the first uplink signal and the first downlink reception includes an association relationship in time domain between the first uplink signal and the first downlink reception, the association relationship in time domain between the first uplink signal and the first downlink reception can be configured by a network side device or agreed by a protocol.

[0071] Optionally, the method further includes:

[0072] The first downlink reception associated with the first uplink signal is triggered according to at least one of a type of the first uplink signal, a logical channel in which the first uplink signal is located, and a service priority of the first uplink signal.

[0073] In this embodiment, different downlink receptions can be associated by different uplink signal types, different downlink receptions can be associated by different service types of uplink signals, and different downlink receptions can be associated by logical channels in which uplink signals are located.

[0074] For example, when a logical channel in which an uplink signal is located is logical channel 1, the uplink signal is associated with downlink reception 1, that is, the uplink signal corresponding to logical channel 1 can trigger or activate downlink reception 1, so that as long as the terminal sends the first uplink signal corresponding to logical channel 1, the downlink reception 1 is implicitly triggered or activated. In this example, the first uplink signal is the uplink signal corresponding to logical channel 1, and the first downlink reception is downlink reception 1.

[0075] The above is an embodiment in which the first downlink reception is triggered by the first uplink signal in an implicit indication manner.

[0076] The following is described in an explicit indication manner.

[0077] Optionally, the first uplink signal includes first indication information, and the first indication information is used to trigger the first downlink reception.

[0078] The first indication information can include an identifier of the first downlink reception, can include a time domain configuration parameter of the first downlink reception, or can include the identifier and the time domain configuration parameter of the first downlink reception. For example, the terminal can send uplink control signaling (such as MAC CE, UCI, etc.), and the uplink control signaling can explicitly indicate the first downlink reception triggered or activated by the uplink control signaling.

[0079] The first downlink reception triggered by the first indication information can be pre-configured by a network side device or pre-agreed by a protocol. For example, the first downlink reception triggered by the first indication information can be configured by RRC. The first downlink reception triggered by the first indication information can include one or more downlink receptions, or the first indication information can trigger multiple first downlink receptions.

[0080] Optionally, the first indication information is used to trigger M first downlink receptions in N downlink receptions, the N downlink receptions are configured by a network side device or agreed by a protocol, and the N and M are integers greater than or equal to 1.

[0081] For example, the RRC configures N downlink receptions, the first indication information is contained in the first uplink signal, and the first indication information is used to trigger or activate M downlink receptions in the N downlink receptions. The M downlink receptions are the first downlink receptions, or the M downlink receptions are M first downlink receptions respectively.

[0082] Optionally, if the M is greater than 1, the method further includes:

[0083] After the first uplink signal is sent, a first downlink control information (DCI) is received.

[0084] K downlink receptions in the M downlink receptions are triggered by the first DCI, the first downlink receptions include the K downlink receptions, and the K is an integer greater than or equal to 1.

[0085] For example, the RRC configures N downlink receptions, the first indication information is contained in the first uplink signal, and the first indication information is used to trigger or activate M downlink receptions in the N downlink receptions. In the downlink receptions, K downlink receptions in the M downlink receptions are dynamically triggered or activated by receiving a DCI.

[0086] The above is an implementation of triggering the first downlink reception by the first uplink signal in an explicit indication manner.

[0087] Optionally, time domain configuration parameters of the first downlink reception are configured by a network side device or agreed by a protocol.

[0088] In the embodiment of the application, the association relationship between the first uplink signal and the first downlink reception can be configured by a network side device or agreed by a protocol. Further, the association relationship between the first uplink signal and the first downlink reception in the time domain can be configured by a network side device or agreed by a protocol. Still further, time domain configuration parameters of the first downlink reception can be configured by a network side device or agreed by a protocol.

[0089] The following describes related implementations of time domain configuration parameters of the first downlink reception.

[0090] Optionally, the time domain configuration parameters of the first downlink reception include at least one of the following:

[0091] A time domain starting moment of the first downlink reception;

[0092] a time domain starting moment of the first downlink reception;

[0093] a duration of the first downlink reception;

[0094] a first periodicity parameter of the first downlink reception, the first periodicity parameter comprising at least one of a first periodicity length, an activation time length of the first periodicity, and an activation time starting position offset of the first periodicity.

[0095] optionally, the time domain starting moment of the first downlink reception is any one of:

[0096] a reference moment, the reference moment being an ending moment of a time domain resource where the first uplink signal is located;

[0097] a first moment, the first moment being a moment that is spaced apart from the reference moment by a first time interval;

[0098] a starting moment of a first available downlink time domain resource after the reference moment;

[0099] a starting moment of a time domain resource after a first timer expires, the first timer being started at the reference moment;

[0100] a starting moment of a first available downlink time domain resource after the first moment;

[0101] a starting moment of a first available downlink time domain resource after the first timer expires.

[0102] The time domain starting moment of the first downlink reception can be an ending moment of a time domain resource where the first uplink signal is located, that is, the terminal can start the first downlink reception immediately after the first uplink signal is sent.

[0103] The time domain starting moment of the first downlink reception can also be the first moment, and a time interval between the first moment and an ending moment of a time domain resource where the first uplink signal is located is the first time interval, that is, the terminal can start the first downlink reception after a first time interval after the first uplink signal is sent, and the first time interval can be configured by a network side device or agreed by a protocol. Further, the network side device can configure multiple first time interval parameters, and the terminal can carry an indication about the first time interval in the first uplink signal. For example, the first time interval can be equal to a time interval K1 of a PDSCH and a HARQ-ACK feedback thereof, and a value set of the K1 is pre-configured by the network side device; or the first time interval can be equal to a time interval between sending a BFRQ (beam failure recovery request) and receiving a BFRR (beam failure recovery response); or the first time interval can be equal to a time interval between sending a RACH and receiving a RAR response.

[0104] The time-domain starting moment of the first downlink reception can also be the starting moment of the first available downlink time-domain resource after the ending moment of the time-domain resource where the first uplink signal is located, that is, the terminal can start the first downlink reception at the first available downlink time-domain resource after the first uplink signal is sent, and the downlink time-domain resource can be a DL subframe, a DL slot, a DL slot containing a CORESET, and the like.

[0105] The time-domain starting moment of the first downlink reception can also be the time-domain resource starting moment after the expiration of the first timer triggered at the ending moment of the time-domain resource where the first uplink signal is located, that is, the terminal triggers the first timer immediately after the first uplink signal is sent, and starts the first downlink reception after the expiration of the first timer.

[0106] The time-domain starting moment of the first downlink reception can also be the starting moment of the first available downlink time-domain resource after the first time interval, that is, the terminal can start the first downlink reception at the first available downlink time-domain resource after the first time interval after the first uplink signal is sent.

[0107] The time-domain starting moment of the first downlink reception can also be the starting moment of the first available downlink time-domain resource after the expiration of the first timer triggered immediately after the first uplink signal is sent, that is, the terminal starts the first downlink reception at the first available downlink time-domain resource after the expiration of the first timer.

[0108] The first time interval can be reported by the terminal according to the capability, or the size of the first time interval can be agreed according to different subcarrier space (SCS) levels, or the terminal can report the first time interval, and the value of the first time interval is not specifically limited.

[0109] In addition, in addition to the above-mentioned time-domain starting moment, the first uplink signal can also include position information (such as a given offset) of the starting moment, and the time-domain starting moment of the first downlink reception is determined according to the starting moment information.

[0110] Optionally, the duration of the first downlink reception includes any one of the first time length and the second timer length.

[0111] In this embodiment, the duration of the first downlink reception can be represented by a first time length, which can be configured by the network side device or agreed by the protocol. The duration of the first downlink reception can also be represented by a second timer length, which can be configured by the network side device or agreed by the protocol.

[0112] Optionally, the time domain monitoring manner of the first downlink reception comprises any one of the following:

[0113] monitoring the first downlink reception within the duration of the first downlink reception;

[0114] monitoring the first downlink reception within the active time of each first cycle within the duration of the first downlink reception;

[0115] monitoring the first downlink reception within the active time of each first cycle within the duration of the first downlink reception.

[0116] If the duration of the first downlink reception is configured, the terminal can monitor the first downlink reception within the duration of the first downlink reception, or in other words, the terminal can uninterruptedly perform the first downlink reception within the duration of the first downlink reception. For example, if the duration of the first downlink reception is a first time length, the terminal can monitor the first downlink reception within the first time length. For another example, if the duration of the first downlink reception is a second timer length, the terminal can monitor the first downlink reception within the second timer length, or in other words, the terminal can uninterruptedly perform the first downlink reception within the second timer length. After the second timer expires, the terminal can exit the first downlink reception triggered by the first uplink signal, and if the terminal receives downlink scheduling information and / or downlink data sending information within the second timer length, the terminal can restart the second timer.

[0117] The terminal can also monitor the first downlink reception in a discontinuous reception manner, i.e., in a periodic time domain monitoring manner. For example, the terminal can monitor the first downlink reception within the active time of each first cycle. The first cycle includes an active time and an inactive time, and the terminal only needs to receive or monitor the first downlink reception within the active time, and does not need to receive or monitor the first downlink reception within the inactive time. The discontinuous reception given in this embodiment can further save the power of the terminal, and is a preferred time domain monitoring manner of the first downlink reception. The first cycle can be a long DRX cycle or a short DRX cycle. If the first cycle is configured as a DRX cycle, the related timers and parameters of the DRX cycle can be further applied to the downlink reception. For example, a DRX-inactivity timer in the DRX cycle.

[0118] The two time-domain monitoring manners can also be combined. For example, the terminal can monitor the first downlink reception in the active time of each first period within the duration of the first downlink reception. In this manner, if the duration of the first downlink reception is a first time length, the monitoring manner is that the terminal can monitor the first downlink reception in the active time of each first period within the first time length of the first downlink reception; if the duration of the first downlink reception is a second timer time length, the monitoring manner is that the terminal can monitor the first downlink reception in the active time of each first period within the running time of the second timer of the first downlink reception. Further, after the duration of the first downlink reception ends, the terminal can no longer use the periodic downlink reception manner.

[0119] In addition, the duration of the first downlink reception can also be carried by the first uplink signal.

[0120] Optionally, the method further comprises:

[0121] If the terminal does not receive Q downlink receptions in the first downlink reception in the active time of L consecutive first periods, the terminal stops monitoring the first downlink reception, where 1≤Q≤L, and L and Q are integers greater than or equal to 1.

[0122] In this embodiment, for the case that the terminal periodically receives the first downlink reception, the time-domain monitoring manner of discontinuous reception is used. If the terminal does not receive downlink scheduling and / or downlink data in the active time of L consecutive first periods, the terminal can exit the first downlink reception, or in other words, the terminal can exit the first downlink reception triggered by the first uplink signal.

[0123] For example, the terminal monitors the first downlink reception in the active time of each first period. If the terminal does not receive any one or more downlink receptions or all downlink receptions in the first downlink reception in the active time of 3 consecutive first periods, the terminal stops monitoring the first downlink reception. For another example, the terminal monitors the first downlink reception in the active time of each first period within the duration of the first downlink reception. If the terminal does not receive all downlink receptions in the first downlink reception in the active time of 3 first periods within the duration of the first downlink reception, the terminal stops monitoring the first downlink reception.

[0124] This embodiment can achieve energy saving of the terminal.

[0125] Optionally, the active time of the first period is indicated by a bitmap method.

[0126] For the active time of the first period described above, the duration can also be indicated.

[0127] For example, "11000" represents a first period, wherein each bit represents 2 ms, the length of the whole first period is 10 ms, and the first 2 bits of 1 represent the active time of the first period and the length of the active time is 4 ms, and the last 3 bits represent the inactive time of the first period and the length of the inactive time is 6 ms.

[0128] Optionally, if the first downlink reception contains the reception of a PDCCH, the time domain configuration parameter of the first downlink reception comprises at least one of the following:

[0129] a blind detection parameter of the PDCCH;

[0130] a monitoring period of the PDCCH;

[0131] a monitoring offset of the PDCCH;

[0132] a monitoring duration of the PDCCH;

[0133] a control resource set (CORESET);

[0134] a search space group;

[0135] a search space;

[0136] a DCI format;

[0137] an RNTI (Radio Network Temporary Identity);

[0138] a time interval between the PDCCH and a physical downlink shared channel (PDSCH) scheduled by the PDCCH;

[0139] a time interval between the PDSCH and a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH;

[0140] a time interval between the PDCCH and a physical uplink shared channel (PUSCH) scheduled by the PDCCH;

[0141] a processing delay of the PDSCH;

[0142] a preparation delay of the PUSCH.

[0143] The time interval related to the PDCCH can include K0, K1, and K2, all of which are in units of slots. K0 is the time interval between the slot in which the DCI (or the PDCCH corresponding to the DCI) is located and the slot in which the PDSCH scheduled by the DCI is located. K2 is the time interval between the slot in which the DCI (or the PDCCH corresponding to the DCI) is located and the slot in which the PUSCH scheduled by the DCI is located. For example, K0 = 0 indicates that the PDCCH and the PDSCH scheduled thereby are in one slot. K1 is the time interval between the slot in which the PDSCH is located and the slot in which the HARQ-ACK feedback is located, that is, the offset in slots.

[0144] The processing delay of the PDSCH refers to the time interval from when the PDCCH schedules the PDSCH to when the HARQ-ACK feedback corresponding to the PDSCH is ready to be sent. The processing delay of the PDSCH is different from K1, which determines the slot in which the HARQ-ACK feedback is performed. However, the processing delay of the PDSCH refers to the time interval that the terminal needs to process after receiving the PDSCH before the HARQ-ACK feedback is ready. That is, K1 must be greater than or equal to the processing delay of the PDSCH.

[0145] The preparation delay of the PUSCH refers to the time interval that the terminal needs to prepare the transmission of the PUSCH scheduled by the PDCCH after receiving the PDCCH. The preparation delay of the PUSCH is different from K2, which determines the slot in which the PUSCH is transmitted. However, the preparation delay of the PUSCH refers to the time interval that the terminal needs to prepare after receiving the PDCCH before the PUSCH is ready to be transmitted. That is, K2 must be greater than or equal to the processing delay of the PUSCH.

[0146] It should be noted that any one or more or all of the time domain configuration parameters of the first downlink reception can be configured by the network side or agreed by the protocol together with other time domain configuration parameters, for example, any one or more or all of the time domain configuration parameters of the first downlink reception can be configured together with any one or more or all of the time domain starting time, the time domain monitoring manner, the time domain duration, and the first periodicity parameter of the first downlink reception. In addition, any one or more or all of the time domain configuration parameters of the first downlink reception can be carried by the first uplink signal together with other time domain configuration parameters.

[0147] Optionally, the association relationship is configured for at least one of a specific terminal, a specific media access control (Media Access Control, MAC) entity, a specific service type, and a specific frequency range.

[0148] Alternatively, the mechanism of triggering the first downlink reception by the first uplink signal can be configured for use by a specific terminal, or for use by a specific MAC entity (such as a MAC entity of an SCG, a MAC entity of an MCG), or for use by a specific service type (such as a specific logical channel (such as logical channel 1)), or for use by a specific frequency range (such as cell 1, BWP 1). The frequency range can be a BWP, a serving cell, or a component carrier. In addition, the association between the uplink signal and the downlink reception for each service type can be configured, which means that the configuration parameters of the mechanism of triggering the first downlink reception by the first uplink signal can be the same or different. The association between the uplink signal and the downlink reception for each BWP of the terminal can also be configured, which means that the configuration parameters of the mechanism of triggering the first downlink reception by the first uplink signal can be the same or different.

[0149] In this embodiment, the mechanism of triggering the first downlink reception by the first uplink signal can be flexibly configured according to specific requirements, which can improve the flexibility of downlink reception of the terminal.

[0150] Optionally, the method further comprises:

[0151] receiving a first message sent by the network side device, the first message being used to instruct the terminal to stop receiving at least one downlink reception in the first downlink reception.

[0152] In this embodiment, the network side device can configure a stop mechanism of the first downlink reception triggered by the first uplink signal, for example, the network side device configures a stop command (such as a MAC CE command, a DCI) for stopping any one or more downlink receptions or all downlink receptions in the first downlink reception currently performed by the terminal. After receiving the first message sent by the network side device, the terminal can stop any one or more downlink receptions or all downlink receptions in the first downlink reception according to the instruction of the first message.

[0153] In this embodiment, the terminal can stop the downlink reception triggered by the uplink signal according to the instruction of the network side device, which is beneficial to improve the working performance and efficiency of the communication system.

[0154] Optionally, the method further comprises:

[0155] receiving a second message sent by the network side device, the second message being used to instruct the terminal to switch the reception period of the first downlink reception from the first period to a second period; the second period being different from the first period in at least one of the period length, the active time length of the period, and the active time starting position offset of the period.

[0156] In this embodiment, the network-side device can configure a dual-cycle switching mechanism for the first downlink reception triggered by the first uplink signal, which is similar to a short DRX cycle and a long DRX cycle switching mechanism. For example, the network-side device can issue a switching command (such as a MAC CE command or a DCI) to instruct the terminal to switch the cycle of the discontinuous reception of the first downlink reception.

[0157] After receiving the second message sent by the network-side device, the terminal can switch the cycle of the first downlink reception to the second cycle according to the indication of the second message. In this way, the flexibility of the first downlink reception can be improved, and the performance of the communication system can be improved.

[0158] Optionally, if the terminal sends a second uplink signal in the duration of the first downlink reception, the second uplink signal is used to trigger a second downlink reception, and the method further includes:

[0159] performing the first downlink reception and the second downlink reception in parallel; or

[0160] only performing the second downlink reception.

[0161] In this embodiment, if the terminal sends another uplink signal (i.e., a second uplink signal) for triggering a second downlink reception in the duration of the first downlink reception triggered by the first uplink signal (i.e., the first downlink reception has not ended), the downlink reception time configuration for this case can include any of the following.

[0162] First, the terminal performs multiple downlink receptions triggered by uplink signals in parallel, or the terminal performs parallel monitoring of the first downlink reception and the second downlink reception. Each uplink signal triggers a monitoring configuration of a downlink reception, for example, a new timer is triggered each time an uplink signal is sent, and the terminal needs to meet the monitoring configuration of the downlink reception triggered by any uplink signal.

[0163] Second, the terminal only performs the downlink reception triggered by a certain uplink signal, or the terminal can only maintain the monitoring configuration of a certain downlink reception. Each time the terminal sends a new uplink signal, the terminal can stop the currently ongoing downlink reception and start a new downlink reception in the monitoring configuration of the new downlink reception. Of course, it is also possible that the terminal continues the currently ongoing downlink reception each time a new uplink signal is sent.

[0164] Optionally, in the case of performing the first downlink reception and the second downlink reception in parallel, if the first downlink reception and the second downlink reception have one or more resource conflicts, the method further includes:

[0165] perform the second downlink reception on the conflicting resources and abandon the first downlink reception; or

[0166] perform the first downlink reception on the conflicting resources and abandon the second downlink reception; or

[0167] determine, according to at least one of a type, a logical channel, and a service priority of the first uplink signal and the second uplink signal, the downlink reception to be performed from the first downlink reception and the second downlink reception on the conflicting resources.

[0168] The resource conflict includes at least one of a time domain resource conflict and a frequency domain resource conflict.

[0169] The embodiment can also be expressed as follows:

[0170] In a case where the first downlink reception and the second downlink reception are performed in parallel, if the first downlink reception and the second downlink reception have one or more resource conflicts, the method further includes:

[0171] receiving a downlink signal in the second downlink reception that conflicts with the first downlink reception and abandoning receiving a downlink signal in the first downlink reception that conflicts with the second downlink reception; or

[0172] receiving a downlink signal in the first downlink reception that conflicts with the second downlink reception and abandoning receiving a downlink signal in the second downlink reception that conflicts with the first downlink reception; or

[0173] determining, according to at least one of a type, a logical channel, and a service priority of the first uplink signal and the second uplink signal, a downlink signal to be received from a downlink signal that conflicts between the first downlink reception and the second downlink reception.

[0174] In the embodiment, when the two downlink receptions have one or more resource conflicts, the terminal can preferentially receive a downlink signal of a downlink reception triggered later and abandon a downlink signal of a downlink reception triggered earlier; the terminal can also preferentially receive a downlink signal of a downlink reception triggered earlier and abandon a downlink signal of a downlink reception triggered later; the terminal can also determine a downlink signal to be received or a downlink signal to be abandoned according to at least one of a type, a logical channel, and a service priority of an uplink signal.

[0175] In this embodiment, the resource conflict can be a time-domain resource conflict only, a frequency-domain resource conflict only, or a time-frequency-domain resource conflict.

[0176] It should be noted that the various optional embodiments in the embodiments of the present application can be combined with each other to implement, or can be implemented independently, and the embodiments of the present application do not limit this.

[0177] In order to better understand the technical solutions of the embodiments of the present application, three specific embodiments are provided below.

[0178] Embodiment one

[0179] As shown in FIGS. 4 to 6, in this embodiment, the network side device pre-configures the association relationship between the uplink signal and the downlink reception, and completes the process of triggering the downlink reception by the uplink signal through implicit indication. The uplink signal triggering downlink reception mechanism is configured for each logical channel. The uplink signal is PUSCH triggering of configurable scheduling (CG), and the time-domain monitoring mode of the downlink reception adopts the discontinuous reception mode of the short DRX cycle. The network configures the first timer of the starting time of the related downlink reception as the length of the waiting monitoring timer and the duration of the downlink reception = delay budget; the set of waiting monitoring timers and the retransmission timers related to the HARQ process in the DRX configured by the DRX can be used at the same time; a MAC CE command is agreed to forcibly stop all ongoing downlink receptions triggered by the uplink signal.

[0180] The network side device pre-configures the association relationship between the uplink signal and the downlink reception. For example, logical channel 1 is mapped to the PUSCH of CG1, and is associated with downlink reception 1 and downlink reception 2; logical channel 2 is mapped to the PUSCH of CG2, and is associated with downlink reception 3.

[0181] The configuration information corresponding to the downlink reception 1 and the downlink reception 2 is basically the same: the same downlink reception time-domain starting time, downlink reception monitoring configuration (using a short DRX cycle, a set of downlink reception waiting monitoring timers and duration delay budget). Among them, the downlink reception types of the two are different, the downlink reception 1 is a semi-persistent SPS PDSCH reception. The downlink reception 2 is a DCI format 1-2 and 0-2 scrambled by C-RNTI.

[0182] The terminal waits for the listening timer to determine the time-domain starting moment of the downlink reception. The duration timer (valid duration) of the downlink reception is set as the delay budget, and after the expiration, the uplink CG triggered by this time is immediately stopped. The downlink reception related listening timer, duration, DRX-HARQ-RTT-TimerDL (downlink DRX-HARQ round trip time timer) and DRX-RetransmissionTimerDL (downlink DRX retransmission timer) in the DRX can coexist.

[0183] In this embodiment, the terminal is configured with a long DRX cycle before receiving the uplink signal triggered downlink reception.

[0184] After the terminal sends the PUSCH of the uplink CG1, the "listening timer" is triggered immediately, and after the expiration of the timer, the short DRX cycle is started immediately, and the downlink scheduling (downlink reception 2) and the reception of the SPS downlink data (downlink reception 1) are performed. In this embodiment, the downlink reception of CG1 uses the configuration related to the short DRX cycle: for example, DRX-ondurationtimer (DRX duration timer) and DRX-inactivitytimer (DRX inactivity timer).

[0185] The configuration information corresponding to the downlink reception 3 is the periodic CSI-RS. The same set of downlink reception listening timer and duration delay budget as the downlink reception 1 and the downlink reception 2. In addition, according to the configured listening period (the period is a newly defined period configuration, not a DRX period), the downlink reception is performed in the active time of each period: the active time position and the duration length are indicated by the bitmap in two slots "11000", indicating that the first 4 slots are active time and the last 6 slots are inactive time.

[0186] The terminal is originally configured with a long DRX cycle. The terminal sends the uplink CG1 PUSCH (data of logical channel 1) and / or CG2 PUSCH (data of logical channel 2) to the network side device, and combines the related configuration in this scheme to give a typical example of the uplink signal triggered downlink reception scheme:

[0187] Example 1: As shown in FIG. 4, only one CG1 PUSCH triggers the downlink reception process, that is, the configuration of the single CG1 PUSCH triggering the downlink reception.

[0188] In FIG. 4, the dashed arrow represents the downlink reception 1: SPS PDSCH reception; and the solid arrow represents the downlink reception 2: PDCCH scheduling.

[0189] Example 2: As shown in FIG. 5, if another uplink CG2 is sent within the duration of the downlink reception triggered by the uplink CG1 (i.e. before the current downlink reception ends), the method of configuring multiple downlink receptions in parallel triggered by multiple uplink signals is selected; the network side device configures a MAC CE command to stop the downlink reception currently being performed. That is, multiple CG PUSCHs overlap, multiple sets of downlink reception configurations need to be met, and a MAC CE command is configured.

[0190] In FIG. 5, the dashed arrow represents downlink reception 1: SPS PDSCH reception; the solid arrow represents downlink reception 2: PDCCH scheduling; and the dotted arrow represents downlink reception 3: CSI-RS.

[0191] Example 3: As shown in FIG. 6, if another uplink CG2 is sent within the duration of the downlink reception triggered by the uplink CG1 (i.e. before the current downlink reception ends), the method of configuring only one downlink reception triggered by one uplink signal is selected, and the network side device does not configure a MAC CE command. That is, multiple CG PUSCHs overlap, the previous downlink reception is stopped, a new downlink reception is started, and no MAC CE command is configured.

[0192] In FIG. 6, the dashed arrow represents downlink reception 1: SPS PDSCH reception; the solid arrow represents downlink reception 2: PDCCH scheduling; and the dotted arrow represents downlink reception 3: CSI-RS.

[0193] Embodiment Two

[0194] This embodiment focuses on the association between uplink signals and downlink receptions and the explicit indication method.

[0195] In this embodiment, the terminal is not configured with a DRX mechanism before receiving the downlink reception triggered by the uplink signal. The terminal sends a MAC CE to the network side device, and the ID of the activated downlink reception is carried in the MAC CE.

[0196] Example 1: As shown in FIG. 7, 5 downlink receptions are configured by RRC, and the 5 uplink receptions are numbered. The terminal sends an uplink control signaling MAC CE to explicitly activate one of the downlink receptions: downlink reception 2.

[0197] Example 2: As shown in FIG. 8, 5 downlink receptions are configured by RRC, and the 5 uplink receptions are numbered. The terminal sends an uplink control signaling MAC CE to explicitly activate 3 of the downlink receptions: downlink receptions 2, 3, and 4. After starting the downlink receptions, a DCI is used to dynamically indicate the activation of one of the 3 downlink receptions: downlink reception 2.

[0198] The configuration information of the downlink reception 2 is that the downlink reception type is a group common PDCCH (PDCCH) scrambled by a C-RNTI, and a set of downlink reception waiting listening N and a time duration timer. After the terminal sends an uplink SR, after N symbols or N ms or N slots, the time duration timer is started and the downlink scheduling reception is started. If the unit of N is a symbol or a slot, the value of N is related to the configuration of SCS. In this example, N is set to 5 ms. The timer is restarted after receiving the downlink scheduling PDCCH in the time duration timer. After the timer expires, the downlink reception in this example is exited.

[0199] Embodiment three

[0200] This embodiment focuses on the method of triggering downlink reception by uplink signal. The downlink reception triggered by the uplink signal is configured to a specific BWP1.

[0201] In this embodiment, the terminal is configured with a long DRX cycle before receiving the downlink reception triggered by the uplink signal. The terminal sends uplink signaling UCI on BWP1, and explicitly carries the configuration information of the downlink reception triggered by the UCI: the time domain starting time of the downlink reception, the listening configuration of the downlink reception, the duration of the downlink reception, and the type of the downlink reception.

[0202] As shown in FIG. 9, the time domain starting time of the downlink reception is the start of the first DL slot containing the CORESET after the UCI. The listening configuration of the downlink reception is a short DRX cycle with a period of 2 ms and an offset of 0. The type of the downlink reception is a periodic PTRS. The duration of the downlink reception is 10 ms.

[0203] The above three embodiments are only exemplary and do not limit the embodiments of the present application.

[0204] In the embodiments of the present application, the terminal can trigger the corresponding downlink reception by sending an uplink signal, which not only saves the resource consumption of the terminal and is beneficial to the energy saving of the terminal, but also improves the flexibility and efficiency of the downlink reception of the terminal. The embodiments of the present application can be applied to but not limited to XR application scenarios, and when the embodiments of the present application are applied to XR application scenarios, the business needs of XR terminals can be better met, and the needs of XR users can be better met.
