Description

Method and device for activating terminal Technical field

This application relates to the field of communication technologies, and in particular to a method and device for activating a terminal.

Background technique

In order to prevent the terminal from continuously monitoring the power consumption caused by the physical downlink control channel (PDCCH), the fifth-generation (5th-generation, 5G) system adopts the discontinuous reception (DRX) mechanism. Under this mechanism, the terminal is in the active state for a part of the time and in the inactive state for a part of the time. When in the active state, the terminal performs PDCCH monitoring, and the terminal does not perform PDCCH monitoring at other times.

PDCCH monitoring is very power-consuming for the terminal. In the dual connectivity (DC) scenario, the terminal performs PDCCH monitoring on frequency range (FR) 2 cells than on FR1 cells. Therefore, how to adjust the PDCCH monitoring process of the terminal so as to control the power consumption of the terminal is a problem to be solved urgently.

In order to make the embodiments of the present application clearer, the following briefly introduces concepts and part of the content related to the embodiments of the present application.

1. PDCCH monitoring

During data transmission, the network device can schedule the terminal. Specifically, the terminal can be assigned a data channel (such as physical downlink shared channel (PDSCH), physical downlink shared channel (PDSCH)) from the resource grid through control information. physical uplink shared channel, PUSCH)) time-frequency resources, network equipment and terminals perform data transmission on the time-frequency resources.

Among them, the downlink control information (DCI) sent by the network device to the terminal is carried in the PDCCH. The PDCCH includes multiple control channel elements (CCE). In NR, the actual physical resource to which a CCE is mapped includes 72 resource elements (RE). The number of CCEs constituting the PDCCH is called aggregation level (AL). The network device can adjust the aggregation level of the PDCCH according to the actual transmission wireless channel state to realize link adaptive transmission.

The aggregation level of the PDCCH actually sent by the network equipment is variable over time, and since there is no related signaling to inform the terminal, the terminal needs to blindly detect the PDCCH under different aggregation levels. The process of blind detection can be called PDCCH monitoring. Among them, the PDCCH to be blindly detected is called a candidate PDCCH. The terminal will decode all candidate PDCCHs in the search space (a set of candidate PDCCHs under a certain aggregation level). If the cyclic redundancy check (CRC) check is passed, the PDCCH is considered The content is valid for the terminal, and subsequent operations are performed according to the information obtained by decoding (for example, transmission scheduling indication, slot format indication, power control command, etc.).

In a wireless network, when data needs to be transmitted, the terminal must always monitor the PDCCH, so as to send and receive data according to the instructions in the PDCCH sent by the network device.

2. DRX mode

Since the packet-based data flow is usually sudden, there is data transmission for a period of time, but there may be no data transmission for a longer period of time. Therefore, the terminal always monitoring the PDCCH will bring greater power consumption to the terminal. In order to reduce the power consumption of the terminal, the DRX mode is proposed.

The DRX mode refers to a working mode in which the terminal only turns on the receiver for PDCCH monitoring during the necessary time period, and turns off the receiver without PDCCH monitoring during the remaining time period to save power consumption of the terminal. The time period during which PDCCH monitoring can be performed is called active time (also referred to as wake-up time), and the state in which PDCCH monitoring can be performed can be referred to as an active state (also can be referred to as an awake state). The time period during which PDCCH monitoring is not performed is referred to as inactive time (also can be referred to as sleep time), and the state in which PDCCH monitoring is not performed can be referred to as an inactive state (also referred to as a sleep state).

The network device configures the DRX parameters for the terminal to enable the terminal to perform the DRX operation (that is, enter the active state and the inactive state at the corresponding time). DRX parameters include: DRX cycle, DRX On Duration Timer (DRX On Duration Timer), DRX Inactivity Timer (DRX Inactivity Timer) (also called inactivity timer), DRX Downlink Retransmission Timer (DRX Retransmission Timer) DL ), DRX uplink retransmission timer (DRX Retransmission Timer UL), random access conflict resolution timer (RA Contention Resolution Timer), long DRX cycle start subframe (long DRX-Cycle Start Offset), short DRX cycle, short DRX cycle timer (Short DRX-Cycle Timer), etc.

In the connected DRX mode, the terminal cannot always turn off the receiver, it must turn on the receiver periodically, and continue to monitor the PDCCH for a period of time. This period of time is called the duration (On Duration), which is defined by DRX On Duration Timer Control, the duration of the timer can be set by parameters.

Among them, the interval between two OnDuration occurrences is the DRX cycle (DRX Cycle) of the DRX mode. Referring to Figure 1, the DRX cycle can be divided into a long DRX cycle and a short DRX cycle. The short DRX cycle and the long DRX cycle may appear alternately, and the specific occurrence time is well known to those skilled in the art, and will not be repeated. In a DRX cycle, the activation time includes:

(1) DRX On Duration Timer, DRX Inactivity Timer, DRX Retransmission Timer DL, DRX Retransmission Timer UL or RA Contention Resolution Timer is running time period.

(2) The time period during which the scheduling request is sent on the physical uplink control channel (PUCCH) and is waiting.

(3) In the case of random access in non-competition mode, after successfully receiving message 2 (Msg2), it has not yet received a cell radio network temporary identifier (C-RNTI) indicating new data transmission. The time period of the PDCCH.

This application mainly involves DRX On Duration Timer and DRX Inactivity Timer. The DRX On Duration Timer is started at the beginning of the DRX cycle. If no other factors affect the activation time of the terminal, the terminal enters the inactive state when the timer stops. DRX Inactivity Timer is used to determine whether the activation time of the terminal is extended due to the arrival of newly transmitted data. If no other factors affect the activation time of the terminal, the terminal enters the inactive state when the timer stops.

Exemplarily, referring to Figure 2, the terminal enters the active state at the start of DRX On Duration Timer of each DRX cycle. If it does not receive (or is called successfully demodulated) during the On Duration period, the PDCCH ( Marked as PDCCH1), the terminal enters the inactive state at the moment when DRX On Duration Timer stops. If PDCCH1 is received during OnDuration, DRX Inactivity Timer is started at the moment when PDCCH1 is received. If the PDCCH (denoted as PDCCH2) that schedules the newly transmitted data is not received during the operation of the DRX Inactivity Timer, the DRX Inactivity Timer enters the inactive state when the DRX Inactivity Timer stops. If PDCCH2 is received during the operation of DRX Inactivity Timer, DRX Inactivity Timer will be restarted at the moment PDCCH2 is received, and so on, until DRX Inactivity Timer stops or other reasons (for example, receiving MAC signaling that makes the terminal enter the inactive state immediately) Cause the terminal to enter the inactive state.

3. Power saving signal (PSS)

The energy saving signal refers to a signal used to control the power consumption of the terminal. Energy-saving signals include wake-up signal (WUS) and go-to-sleep signal (GTS). Optionally, WUS is bound to DRX mode, and GTS is not bound to DRX mode.

4. WUS

WUS is a signal used to indicate whether the terminal enters the active state at the beginning of the on duration. The terminal detects WUS for a period of time before onduration (this time period can be configured). If WUS is detected (or WUS is detected and WUS indicates that the terminal wakes up), the terminal enters the active state at the beginning of onduration, otherwise The terminal continues to remain inactive during on duration.

WUS can correspond to multiple DRX cycles, that is, when the terminal detects WUS (or WUS is detected and WUS instructs the terminal to wake up), it enters the active state at the beginning of the on duration of multiple DRX cycles, otherwise, in multiple DRX cycles The on duration of the cycle continues to remain inactive.

5. GTS

GTS is a signal used to instruct the terminal to enter the inactive state. When the terminal in the active state detects the GTS (or, detects the GTS and instructs the terminal to enter the inactive state), it enters the inactive state, and the duration of the inactive state is configurable.

6. FR

Currently, 5G spectrum resources can be divided into two FRs, denoted as FR1 and FR2.

FR1: The frequency band below 6GHz (Sub 6GHz), that is, the low frequency band, is the main frequency band for 5G. Among them, the frequency band below 3GHz can be called sub3GHz frequency band, and the remaining frequency bands can be called C-band frequency band.

FR2: The frequency band higher than 6GHz, that is, the high-frequency band, is an extended frequency band of 5G with abundant spectrum resources.

For example, see Table 1 for the frequency ranges corresponding to FR1 and FR2 respectively.

FR1	450MHz-6000MHz
FR2	24250MHz-52600MHz

Then, the network device 410 may be called a master node (MN). For example, the master node may be a master evolved NodeB (MeNB) or a master next generation node base station (MgNB), which is not limited Here; another network device, such as network device 420, can be called a secondary node (SN), for example, the secondary node can be a secondary evolved base station (secondary evolved NodeB, SeNB) or a secondary next-generation base station node (secondary next generation node base station, SgNB), not limited to this.

The plurality of antennas may include at least one transmitting antenna for transmitting signals and at least one receiving antenna for receiving signals. In addition, each communication device additionally includes a transmitter and a receiver. Those of ordinary skill in the art can understand that each of them can include multiple components related to signal transmission and reception (such as processors, modulators, multiplexers, and decoders). Tuner, demultiplexer or antenna, etc.). Therefore, multiple antenna technology can be used to communicate between network devices and terminals.

When the terminal accesses both the FR1 cell and the FR2 cell, the PDCCH monitoring of the terminal on the FR2 cell consumes more power than the PDCCH monitoring on the FR1 cell. Therefore, in order to adjust the PDCCH monitoring process of the terminal to control Terminal power consumption. This application provides a method for activating a terminal, as shown in Figure 5, including:

501. The terminal enters an active state in the first frequency cell accessed by the terminal (the first frequency cell hereinafter refers to the first frequency cell accessed by the terminal).

502. The terminal receives a PDCCH (denoted as the first PDCCH) used for scheduling data in the first frequency cell during the active state of the first frequency cell.

Among them, the data scheduled by the first PDCCH may be newly transmitted data. The first PDCCH may be sent by the first network device to the terminal, and the first network device is a network device to which the first frequency cell belongs.

503. At the moment when the first PDCCH is received, the terminal enters an active state in the second frequency cell accessed (the second frequency cell hereinafter refers to the second frequency cell accessed by the terminal).

Wherein, the first frequency is less than the second frequency. At this time, the first frequency cell may be an FR1 cell or a low frequency cell. The second frequency cell may be an FR2 cell or a high frequency cell.

The first frequency cell and the second frequency cell may be in the same cell group, and the cell group may consist of multiple cells covered by one network device, for example, the scenario shown in FIG. 3. The first frequency cell and the second frequency cell may also be in different cell groups. For example, in the DC scenario shown in Figure 4, if the MCG includes multiple FR1 cells and the SCG includes multiple FR2 cells, the first frequency cell may be located in the MCG , The second frequency cell may be located in the SCG; if the SCG includes multiple FR1 cells and the MCG includes multiple FR2 cells, the first frequency cell may be located in the SCG, and the second frequency cell may be located in the MCG.

Optionally, the first frequency cell is configured with DRX parameters, and the second frequency cell is not configured with DRX parameters. In this case, the method further includes: the first network device or the second network device configures DRX parameters for the terminal in the first frequency cell, and the DRX parameters are only applicable to the first frequency cell. Wherein, the second network device is a network device to which the second frequency cell belongs.

For the second frequency cell, in addition to using step 503 to enter the active state, the terminal can also enter the active state in the second frequency cell immediately when the first frequency cell enters the active state, or the terminal can be in the first frequency cell After entering the activated state, after a preset time period (for example, a preset time period, or the time period between the time when the terminal detects WUS and the start time of on duration), the second frequency cell is also activated status.

In the method provided by the embodiments of the present application, if the PDCCH (for example, the first PDCCH) for scheduling data is received in the first frequency cell, that is, when there is data transmission, the terminal enters the active state in the second frequency cell. Do not enter the active state in the second frequency cell during data transmission, thereby reducing the PDCCH monitoring time on the second frequency cell and reducing the power consumption of the terminal. In addition, when the amount of data of the terminal is relatively large, since the second frequency cell has a larger bandwidth, data reception in the first frequency cell and the second frequency cell at the same time is beneficial to improve the transmission efficiency of the terminal.

Optionally, the duration that the terminal is in the active state in the second frequency cell is the first duration. Exemplarily, referring to FIG. 6, when the terminal receives the first PDCCH while the first frequency cell is in the active state, the terminal enters the active state in the second frequency cell for the first time period.

The first duration can include but is not limited to the following situations:

1) The first duration is preset, for example, preset in the terminal.

2) The first duration is pre-configured, for example, the first network device or the second network device is pre-configured for the terminal.

3) The first duration is stipulated in the agreement.

4) The first duration is the duration of the DRX duration timer in the DRX parameter corresponding to the first frequency cell (that is, the duration of on-duration). Exemplarily, if the duration of the DRX duration timer in the DRX parameter corresponding to the first frequency cell is 5 ms, the first duration is 5 ms.

5) The first duration is the duration between the time when the terminal enters the active state in the second frequency cell and the time when the terminal enters the inactive state in the first frequency cell. That is, when the terminal enters the inactive state in the first frequency cell, it also enters the inactive state in the second frequency cell. Exemplarily, if the terminal enters the active state in the first frequency cell at time T1, receives the first PDCCH at time T2 after time T1, and enters the inactive state at the first frequency cell at time T3 after time T2, the terminal The activated state is performed in the second frequency cell at time T2 and lasts for a first time period. The first time period is a time period between T2 and T3.

Optionally, the above method further includes:

11) Within the first time period, the terminal receives the PDCCH (denoted as the second PDCCH) of scheduling data in the second frequency cell.

12) At the moment when the second PDCCH is received, the terminal maintains the active state in the second frequency cell, and the active state is maintained for the second duration.

Exemplarily, referring to FIG. 7, based on the example shown in FIG. 6, if the terminal receives the second PDCCH within the first period of time, it will maintain the active state for the second period of time starting from the moment when the second PDCCH is received.

This optional method can ensure that when the second frequency cell always has data scheduling, the terminal always maintains the active state in the second frequency cell, and completes the data transmission and reception on the second frequency cell.

Among them, the data scheduled by the second PDCCH is newly transmitted data.

Optionally, the second duration can have the following situations:

1) The second duration is preset, for example, preset in the terminal.

2) The second duration is pre-configured, for example, the first network device or the second network device is pre-configured for the terminal.

3) The second duration is stipulated in the agreement.

In case 1) to case 3), the second duration may be equal to the first duration, or greater than the first duration, or less than the first duration, which is not limited in this application.

4) The second duration is the duration of the DRX static timer in the DRX parameter corresponding to the first frequency cell. Exemplarily, if the duration of the DRX static timer in the DRX parameter corresponding to the first frequency cell is 10 ms, the second duration is 10 ms.

In the DC scenario, you can set "During the period when the terminal is in the active state of the first frequency cell, if the PDCCH for scheduling data is received in the first frequency cell (for example, the above-mentioned first PDCCH), the terminal enters the active state in the second frequency cell. The activation mechanism of "state" is called the follow-up activation mechanism of the second frequency cell. At this time, the above method also includes:

21) The first network device generates instruction information (denoted as the first instruction information), and sends the first instruction information to the terminal through the second network device. The first instruction information is used to indicate whether to enable the follow-up activation mechanism of the second frequency cell. Correspondingly, the terminal receives the first indication information.

Wherein, the second network device may forward the first instruction information sent by the first network device to the terminal.

The first indication information may be carried in RRC signaling or MAC control element (MAC control element, MAC CE) signaling or DCI.

22) The terminal determines whether to enable the follow-up activation mechanism of the second frequency cell according to the first indication information. If the first indication information indicates to enable the follow-up activation mechanism of the second frequency cell, the terminal executes the above method; otherwise, the terminal is always in an inactive state in the second frequency cell.

In this case, the terminal can activate the terminal only when the follow-up activation mechanism of the second frequency cell is turned on, and the terminal is always in an inactive state without opening the follow-up activation mechanism of the second frequency cell, thereby further reducing the terminal’s Power consumption.

Optionally, the above method further includes:

31) The terminal detects the first signal before entering the activation time. The activation time is the time when the terminal enters the activated state in the first frequency cell. The first signal is used to instruct to activate the terminal in the first frequency cell. Wherein, the activation time can be the start time of on duration, or the time when the terminal actually enters the activated state. The first signal may be WUS, or may be another signal indicating that the terminal enters the active state in the first frequency cell at the time of activation. In this case, when step 501 is specifically implemented, the terminal enters the activated state at the first frequency cell accessed by the terminal at the activation time according to the first signal.

The first signal may be carried in RRC signaling or MAC control element (MAC control element, MAC CE) signaling or DCI.

The first signal may correspond to one or more DRX cycles. Specifically, several DRX cycles may be indicated by the first signal or specified by the protocol, configured by the first network device, configured by the second network device, or passed by the first network device. The broadcast information indicates or the second network device indicates through the broadcast information. In this case, the terminal detects the first signal, and enters the activated state at the first frequency cell accessed by the terminal according to the first signal at the activation time of multiple DRX cycles.

In a DC scenario, the first signal may be sent by the first network device, or it may be sent by the second network device.

The realization of the first signal can have the following situations:

1) The first signal is only used to indicate that the terminal enters the active state in the first frequency cell accessed. In this case, if the terminal detects the first signal, it enters the active state in the first frequency cell.

2) The first signal can not only be used to instruct the terminal to enter the active state in the first frequency cell, but also can be used to instruct the terminal to enter the inactive state or not to enter the active state in the first frequency cell. In this case, if the terminal detects the first signal, and the first signal indicates that the terminal enters the active state in the first frequency cell, it enters the active state in the first frequency cell. At this time, it can be understood that the first signal also has the function of GTS.

Exemplarily, the first signal corresponds to 1 bit. When this bit is set to 1, it indicates that the terminal enters the active state in the first frequency cell, and when the bit is set to 0, it indicates that the terminal does not enter the active state in the first frequency cell. In this case, if the terminal detects the first signal, and the bit corresponding to the first signal is set to 1, it enters the active state in the first frequency cell; otherwise, the terminal does not enter the active state in the first frequency cell.

Wherein, the second network device is a network device to which the second frequency cell belongs.

802. The first frequency cell accessed by the terminal performs a DRX operation according to the DRX parameter.

803. The first network device sends a second signal to the terminal before the activation time corresponding to the first frequency cell. Correspondingly, the terminal receives the second signal from the first network device before the activation time corresponding to the first frequency cell.

Among them, the activation moment is the starting moment of on duration. The second signal may be WUS or another signal indicating that the terminal enters the active state in the second frequency cell.

In this process, the terminal only performs DRX operation in the first frequency cell, and only after receiving the second signal indicating that the terminal enters the active state in the second frequency cell, will it enter the active state in the second frequency cell and perform PDCCH monitoring. , Can reduce the power consumption of the terminal.
