detailed description

In the NR FDD system, a UE can be configured with 4 DL BWP and 4 UL BWP at most. In the NR TDD system, a UE can be configured with 4 BWP Pairs at most. BWP Pair means that DL BWP ID and UL BWP ID are the same, and the center frequency of DL BWP and UL BWP are the same, but the bandwidth and subcarrier spacing may not be consistent. BWP is mainly divided into two categories: initial BWP (Initial BWP) and dedicated BWP (Dedicated BWP). The initial BWP is mainly used for the UE to receive residual system information (RMSI) and other system information (OSI) to initiate random access. The dedicated BWP is mainly used for data service transmission, and the bandwidth of the dedicated BWP is generally larger than the initial BWP. The initial BWP is sometimes referred to as the default BWP.

In addition to the network instructing the UE to perform BWP handover, the UE can also trigger BWP handover by itself, such as random access triggered by a scheduling request (SR). There is no physical random access channel (PRACH, Physical Random Access Channel) resource in the current BWP When the time, the UE will trigger the handover to the initial BWP. Another example is random access triggered by Beam Failure Recovery (BFR). When the current BWP does not have PRACH resources, the UE will trigger a handover to the initial BWP.

The BWP switching of NR can be through physical downlink control channel (PDCCH), or radio resource control (RRC) signaling, or based on the bandwidth part inactivity timer (bwp-InactivityTimer). In this article, the bandwidth part inactive timer is sometimes referred to as the BWP inactive timer. Among them, if the terminal is not working in the default downlink BWP or initial downlink BWP, each time the terminal receives a PDCCH or media access control protocol data unit (MAC PDU) on the currently activated BWP (such as a dedicated BWP) When transmitting in uplink scheduling, start or restart bwp-InactivityTimer. When the bwp-InactivityTimer expires, the terminal automatically switches to the default downlink BWP or transmits the downlink BWP.

In the discontinuous reception (DRX) process of NR, high-level signaling configures various DRX timers for the terminal, as well as the length and start position of the short DRX cycle (short DRX cycle) and the long DRX cycle (long DRX cycle). The DRX process is divided into an active period and an inactive period. The terminal detects the PDCCH during the DRX active period and does not need to detect the PDCCH during the inactive period to achieve energy saving. As shown in FIG. 1, in the DRX cycle, the terminal usually detects the PDCCH during the Active Time, and does not need to detect the PDCCH during the inactive period.

However, in some DRX cycles, there may be cases where the base station does not schedule the terminal. Therefore, in the NR system, the network side can configure the DRX energy-saving signal for the terminal. The time-domain position of the energy-saving signal is before the DRX cycle (that is, Before the terminal starts the drx-onDurationTimer timing). If the terminal detects the energy-saving signal, the terminal wakes up in the next DRX cycle, starts drx-onDurationTimer, and detects the PDCCH during the activation period; if the energy-saving signal is not detected, the terminal does not need to wake up in the next DRX cycle Detect PDCCH.

The R15DRX process and the BWP process of the related technology are separate processes, that is, in the DRX process, due to the expiration of the bwp-InactivityTimer, the terminal will automatically switch to the default downlink BWP or the initial downlink BWP. BWP switching based on bwp-InactivityTimer mainly considers that the terminal has no service requirements for a certain period of time, and it can be automatically switched to the default downlink BWP or initial downlink BWP with a smaller bandwidth to achieve terminal energy saving.

However, after the DRX process of introducing the energy-saving signal, since the energy-saving signal may be sent before the DRX cycle, there is a certain time context to the position where the bwp-InactivityTimer expires, which may cause certain confusion to the PDCCH detection behavior of the terminal.

For example, please refer to FIG. 1, the terminal works on the activated downlink BWP#1, and after the expiration of the DRX inactivity timer (drx-InactivityTimer), it enters the dormant state and no longer detects the PDCCH. If the terminal receives an energy saving signal before a certain DRX cycle starts, the energy saving signal indicates that the terminal needs to wake up in the next DRX cycle. After the terminal receives the energy-saving signal, its bwp-InactivityTimer expires, and when the bwp-InactivityTimer expires, it has not reached the start position of the next DRX cycle.

According to the respective process design principles of DRX and BWP, the terminal needs to switch to the default or initial downlink BWP first, but the network side has already sent an energy-saving signal before the expiration of the bwp-InactivityTimer to notify the terminal to wake up in the next DRX cycle, which usually means The DRX cycle that needs to be awakened is a large amount of data transmission of the terminal, so the better BWP of the terminal should be a BWP with a larger bandwidth, and it should not be switched to the default or initial downlink BWP with a smaller bandwidth. Therefore, if you switch Reaching a BWP with a smaller bandwidth will result in a decrease in the transmission rate of the terminal and increase in the transmission time of data packets, which will result in a decrease in the energy saving effect of the terminal.

Therefore, in the DRX process that introduces the energy-saving signal, it is necessary to consider the BWP process after the terminal receives the energy-saving signal, that is, after receiving the energy-saving signal, it does not need to switch to the default or initial downlink BWP according to the bwp-InactivityTimer In order to achieve the best energy saving effect, the PDCCH and data should be received on the currently activated downlink BWP.

Please refer to FIG. 2, which shows a block diagram of a wireless communication system to which some embodiments of the present disclosure are applicable. The wireless communication system includes a terminal 21 and a base station 22. Among them, the terminal 21 may also be referred to as a user terminal or a user equipment (UE, User Equipment), and the terminal 21 may be a mobile phone, a tablet (Personal Computer), a laptop (Laptop Computer), or a personal digital assistant (Personal Digital Assistant). , PDA), mobile Internet device (Mobile Internet Device, MID), wearable device (Wearable Device), or in-vehicle equipment and other terminal side devices, it should be noted that in some embodiments of the present disclosure, the terminal 21 is not limited Specific type.

It should be noted that in some embodiments of the present disclosure, only the base station in the NR system is used as Example, but does not limit the specific type of base station.

The base station 22 may communicate with the terminal 21 under the control of the base station controller. In various examples, the base station controller may be a part of a core network or some base stations. Some base stations can communicate control information or user data with the core network through the backhaul. In some examples, some of these base stations may directly or indirectly communicate with each other through a backhaul link, which may be a wired or wireless communication link. The wireless communication system can support operations on multiple carriers (waveform signals of different frequencies).

For example, each communication link may be a multi-carrier signal modulated according to various radio technologies.

It should be noted that the network equipment of some embodiments of the present disclosure may be implemented by the base station (access network node) in FIG. 2, or by the core network node, or by the access network node and the core network node.

Referring to FIG. 3, the method for adjusting the bandwidth part timer provided by some embodiments of the present disclosure, applied to a terminal, includes:

Step 31: Receive the first signal or the configuration information of the first signal associated with the first bandwidth part.

Here, the first signal is used to instruct the terminal to start the discontinuous reception duration timer or start detecting the PDCCH or enter the activation period of discontinuous reception at the first moment, and the first bandwidth part is except the initial bandwidth part and the default Other bandwidth parts other than the bandwidth part, for example, the first bandwidth part may be a dedicated bandwidth part (Dedicated BWP), and the bandwidth is usually greater than the initial bandwidth part or the default bandwidth part. The first moment may specifically be:

The time at which the discontinuous reception duration timer (drx-onDurationTimer) is started closest to the receiving time of the first signal;

Or, the moment when the discontinuous reception duration timer (drx-onDurationTimer) is started, which is associated with the first signal;

Step 32: The terminal adjusts a bandwidth part inactivation timer associated with the first bandwidth part.

Here, after receiving the first signal or the configuration information of the first signal, the bandwidth part inactivity timer (bwp-InactivityTimer) associated with the first bandwidth part may be determined according to the first signal or the configuration information of the first signal. ) To adjust the current active bandwidth of the terminal. For example, you can cancel or stop the inactive timer of the bandwidth to avoid changing the active bandwidth, so that the terminal can receive PDCCH and data on the currently active downlink BWP. This prevents the terminal from switching to the initial downlink BWP/default downlink BWP with a smaller bandwidth for PDCCH detection and data reception, resulting in reduced data transmission rate, increased transmission time, and reduced energy-saving effects, which can improve the actual energy-saving effect of the terminal.

In some embodiments of the present disclosure, the adjustment method of adjusting the bandwidth part inactivation timer associated with the first bandwidth part may specifically be stopping, canceling, and restarting the bandwidth part inactivation timer associated with the first bandwidth part The configuration information of the bandwidth part inactivation timer associated with the first downlink bandwidth part may also be ignored, and so on.

Wherein, stopping the bandwidth part inactive timer associated with the first bandwidth part is usually after the bandwidth part inactive timer associated with the first bandwidth part has started to count, stop the timer counting, thereby It is possible to avoid the switching process of the active bandwidth part triggered by the timer timeout.

Restart the bandwidth part inactive timer associated with the first bandwidth part, usually after the bandwidth part inactive timer associated with the first bandwidth part has started to count, restart the timer Start timing from 0, which can delay or avoid the switching process of the active bandwidth part triggered by the timer timeout.

Canceling the bandwidth part inactivation timer associated with the first bandwidth part may be to delete the timer, so as to avoid the switching process of the active bandwidth part triggered by the timer timeout.

Ignoring the configuration information of the bandwidth part inactive timer associated with the first downlink bandwidth part means that after the timer has been configured, the timer will no longer be started based on the configuration information of the timer, thus It can also avoid the switching process of the active bandwidth part triggered by the timer timeout.

The above steps will be described in more detail below through multiple implementations. In the following implementation manner, the first downlink BWP is a BWP other than the initial BWP and the default BWP. Specifically, the first downlink BWP may be a dedicated BWP whose bandwidth is greater than the initial BWP or the default BWP.

As an implementation manner, the downlink BWP currently activated by the terminal is the first downlink BWP. In this implementation manner, in the above step 31, the terminal receives the first signal on the first downlink BWP currently activated. In the above step 32, the terminal stops the bandwidth part inactivation timer associated with the first downlink bandwidth part, or restarts the bandwidth part inactivation timer associated with the first downlink bandwidth part, so that After receiving the first signal, the above-mentioned bandwidth part inactivation timer can be stopped or restarted, so as to avoid the switching of the activated BWP caused by the timer timeout.

In this way, when the terminal is working in the discontinuous reception state, by restarting or stopping the bandwidth part inactivity timer (bwp-InactivityTimer), it is possible to avoid the bwp-InactivityTimer expiration triggering the terminal’s active BWP from the current first downlink The BWP is switched to the initial downlink BWP/default downlink BWP to ensure that the terminal continues to work in the first downlink BWP, so that the terminal can wake up during the active period of the DRX cycle to perform PDCCH detection and data reception. Since the bandwidth of the first downlink BWP is usually not less than the initial downlink BWP/default downlink BWP, the terminal can use a larger bandwidth to implement faster data transmission, which saves the time the terminal is in the active state and reduces the power consumption of the terminal. Moreover, the terminal can enter the dormant state earlier after completing the data transmission, which is also beneficial to reduce the power consumption of the terminal.

Figure 4 shows a specific example of the above implementation, where the terminal receives the first signal in the DRX cycle n, and the first signal instructs the terminal to start detecting the PDCCH at the first moment. The most recent moment when drx-onDurationTimer is turned on at the receiving moment of the first signal, that is, the starting moment of drx-onDurationTime in the DRX cycle n+1. At this time, after receiving the first signal, the terminal will stop or restart the bwp-InactivityTimer, which can avoid the switch of activated BWP triggered by the expiration of bwp-InactivityTimer, and ensure that the terminal wakes up and detects on DL BWP#1 PDCCH and data transmission can achieve better energy-saving effects.

As another implementation manner, in the above step 31, the downlink BWP currently activated by the terminal may be the first downlink BWP, or the initial BWP or the default BWP. In the above step 31, the terminal receives the configuration information of the first signal associated with the first downlink bandwidth part configured by the higher layer signaling, and the configuration information of the first signal is used to configure the configuration information associated with the first downlink bandwidth part. The first signal. In the foregoing step 32, the terminal ignores the configuration information of the bandwidth part inactivation timer associated with the first downlink bandwidth part, and/or stops or cancels the bandwidth associated with the first downlink bandwidth part Partial inactivation timer, so that after receiving the first signal, you can avoid starting the bandwidth part inactivation timer, or you can stop or cancel the bandwidth part inactivation timer, so as to avoid activation caused by timer timeout BWP switching.

In this other implementation manner, if the terminal receives the configuration information of the first signal configured through high-level signaling, it means that there may be subsequent data transmission of the terminal. Therefore, the terminal can ignore the information associated with the first signal. The configuration information of bwp-InactivityTimer on the first downlink BWP, so that bwp-InactivityTimer can be ignored (for example, bwp-InactivityTimer is not started on the first downlink BWP), and/or the terminal can stop communicating with the first downlink Bwp-InactivityTimer associated with BWP. Through the above implementation, the terminal can refuse to start the bwp-InactivityTimer on the first BWP, or stop/cancel the bwp-InactivityTimer started on the first BWP, so as to avoid the switch to activate the BWP triggered by the expiration of the bwp-InactivityTimer, and guarantee The terminal wakes up on DL BWP#1 and detects PDCCH and performs data transmission, which can achieve better energy-saving effects.

As yet another implementation manner, in step 31, the currently activated downlink BWP of the terminal is the first downlink BWP, and after the terminal receives the configuration information of the first signal on the currently activated first downlink BWP Perform the processing of step 32, or when the downlink BWP activated by the terminal is not the first downlink BWP, the terminal receives the configuration information of the first signal, and subsequently when the first downlink BWP is activated, the The terminal performs the processing of step 32 again. In the foregoing step 32, the terminal ignores the configuration information of the bandwidth part inactivation timer associated with the first downlink bandwidth part, and/or stops or cancels the bandwidth associated with the first downlink bandwidth part Partially inactive timer.

In this yet another implementation manner, the terminal will wait for the activation of the first downlink BWP or receive the configuration information of the first signal associated with the activated first downlink BWP before it considers that the preset condition is satisfied At this time, the terminal can ignore the configuration information of bwp-InactivityTimer associated with the first downlink BWP, so that bwp-InactivityTimer can be ignored (for example, bwp-InactivityTimer is not started on the first downlink BWP), and/or the terminal The bwp-InactivityTimer associated with the first downlink BWP can be stopped/cancelled. Through the above implementation, the terminal can refuse to start the bwp-InactivityTimer on the first downlink BWP, or stop the bwp-InactivityTimer started on the first downlink BWP, thereby avoiding the switch to activate the BWP triggered by the expiration of the bwp-InactivityTimer This ensures that the terminal wakes up on DL BWP#1 and detects PDCCH and performs data transmission, which can achieve better energy-saving effects.
