Description

System information receiving method and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and a terminal for receiving system information.

Background

In a fifth generation (5G) mobile communication system, one cell on the network side may support a relatively large bandwidth (e.g., 100MHz), and a terminal (UE) may only support a relatively small operating bandwidth (e.g., 5MHz) in the large bandwidth. The small Bandwidth Part of the large Bandwidth where the UE operates is referred to as a Bandwidth Part (BWP). From a UE configuration perspective, one or more BWPs may be configured for different UE capabilities. The network side may configure 1 or more BWPs for the UE, and change the BWP that the UE can operate by activating or deactivating the BWPs.

The following presents a simplified summary of relevant background that may be involved with embodiments of the present invention.

In the 5G System, the type of System Information (SI) may include:

1) master Information Block (MIB, Master Information Block)

The MIB may be issued simultaneously with a Synchronization Signal Block (SSB), and may contain scheduling Information for Remaining System Information (RMSI).

2) Remaining System Information (RMSI)

RMSI is some system information required for the UE to operate in a cell, such as system information block 1(SIB1) and system information block 2(SIB2) like Long Term Evolution (LTE) system. Scheduling information for Other system information (Other SI) may be included in the RMSI.

3) Other System information (OSI, Other SI)

OSI is System information supporting other auxiliary functions, such as Earthquake and Tsunami Warning System (ETWS) information like LTE System and Commercial Mobile Alert Service (CMAS) System information.

In a mobile communication system, Paging (Paging) information may be used to indicate update of system information and to indicate traffic arrival of a UE. The UE may receive paging information in an IDLE state (IDLE) or an INACTIVE state (INACTIVE) by using a Discontinuous Reception (DRX) mode.

When the UE operates on a certain active BWP, the network side may send system information on another BWP. For example, the UE may receive paging information on the active BWP, which informs the UE of system information update, and the updated system information is transmitted on the inactive BWP of the terminal, which is different from the currently active BWP of the UE. The prior art has no specific processing scheme for the case where system information is transmitted on the inactive BWP of the terminal.

Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

In embodiments of the present invention, a terminal may be involved. The terminal may be a mobile phone (or handset), or other device capable of sending or receiving wireless signals, including a User Equipment (UE), a Personal Digital Assistant (PDA), a wireless modem, a wireless communicator, a handheld device, a laptop computer, a cordless phone, a Wireless Local Loop (WLL) station, a CPE (Customer Premise Equipment) or mobile smart hotspot capable of converting mobile signals to WiFi signals, a smart appliance, or other device capable of autonomously communicating with a mobile communication network without human operation, etc. In addition, the terms "system" and "network" are often used interchangeably herein.

An embodiment of the present invention provides a method for receiving system information, where the method may be applied to a terminal, and as shown in fig. 1, the method includes:

and step 11, the terminal determines that the first system information needs to be received.

And step 12, when the first currently activated BWP is different from the second BWP where the first system information is located, the terminal deactivates the first BWP and activates the second BWP.

Here, for convenience of description, the BWP currently activated by the terminal is referred to as a first BWP, and the BWP where the first system information is located is referred to as a second BWP, that is, the network side transmits the first system information on the second BWP, which may specifically be transmitted by means of broadcast paging (paging) information.

In order to receive the first system information, the terminal needs to change the currently activated BWP, i.e., deactivate the first BWP, and activate the second BWP. It should be noted that there is no strict sequential relationship between deactivating the first BWP and activating the second BWP, and the embodiment of the present invention may deactivate the first BWP first and then activate the second BWP, or activate the second BWP first and then deactivate the first BWP, and of course, may also perform the above deactivation and activation operations at the same time.

Step 13, the terminal receives the first system information on the second BWP.

After changing the active BWP, the terminal may receive the first system information on the second BWP.

Through the above steps, when the first system information is transmitted on the inactive BWP of the terminal, the embodiment of the present invention may change the currently active BWP of the terminal to receive the system information, thereby providing a system information receiving scheme in the above situation.

Specifically, whether the terminal needs to receive the first system information may include at least one of the following examples:

for example, the terminal may determine that the first system information needs to be received when receiving indication information sent by a network and indicating that the first system information is updated, and then further determine whether the first BWP is different from the second BWP. The indication information may specifically be paging information sent by a network, or information carried in the paging information.

For another example, the terminal may determine that the first system information needs to be received when the terminal needs to initiate a service related to the first system information.

As one implementation, in the above reception scheme, when the terminal changes the active BWP, the terminal may continue to operate with the active BWP (second BWP) after the change. In order to keep the network side and the terminal side consistent with the activated BWP and avoid the loss of data transceiving, the terminal may further notify the network that the second BWP is activated. In this embodiment, the terminal may notify the first BWP or the second BWP, for example, the terminal may notify the network that the second BWP is activated on the second BWP after activating the second BWP. For another example, the terminal may notify the network that the second BWP is to be used on the first BWP before deactivating the first BWP, so as to indicate that the terminal is about to activate the second BWP, and then the terminal goes to perform the above processes of deactivating the first BWP and activating the second BWP.

Specifically, there are various ways to notify the network that the second BWP is activated on the second BWP, or to notify the network that the second BWP is to be used on the first BWP.

For example, the terminal may initiate a random access procedure on the second BWP after activating the second BWP, the random access procedure including a contention-based random access procedure and a non-contention-based random access procedure. The network side may determine the BWP currently activated by the terminal based on the BWP initiated by the terminal, thereby implementing the notification.

For another example, the terminal may send uplink signaling indicating that the second BWP is activated to the network on the second BWP after activating the second BWP.

For another example, the terminal may send uplink signaling indicating that the second BWP is to be used to the network on the first BWP before deactivating the first BWP.

Here, the uplink signaling sent on the first BWP or the second BWP may include at least one of the following signaling: radio Resource Control (RRC) signaling; media Access Control (MAC) signaling, such as MAC Control element (MACCE); and, physical layer signaling.

Specifically, the uplink signaling may include at least one of an identifier of the first BWP and an identifier of the second BWP. For example, after the uplink signaling only includes the identifier of the deactivated first BWP, the network side receives the deactivated first BWP, and may determine that the activated BWP of the terminal changes, and further determine that the changed activated BWP is the second BWP according to the BWP where the first system information that the terminal needs to receive is located. For another example, when the uplink signaling only includes the identifier of the activated second BWP, or includes the identifiers of the deactivated first BWP and the activated second BWP, the network may determine the activated BWP after the change as the second BWP directly according to the uplink signaling.

As another implementation manner, in the above receiving scheme, after the terminal changes the active BWP, after step 12, the terminal may deactivate the second BWP and/or activate the first BWP after the end of receiving the first system information. Since the terminal reactivates the first BWP or deactivates the second BWP, the terminal may not notify the network of the change in the activated BWP.

Here, the terminal may determine that the first system information is received successfully before a predetermined reception opportunity ends, or when the first system information is not received yet after the predetermined reception opportunity ends. That is, if the first system information is successfully received before the predetermined reception timing ends, the reception is considered to be ended, or the first system information is not successfully received before the predetermined reception timing ends, the reception is considered to be ended.

Specifically, the predetermined receiving timing includes at least one of the following timings:

within a timeout period defined by a preset timer;

a preset counter defines a maximum number of reception attempts of the first system information.

The way in which the above-mentioned timer or counter is maintained is given further below.

For the timer, the terminal maintains the timer according to at least one of the following modes:

1) the terminal starts the timer when receiving the first system information for the first time;

2) the terminal starts the timer when activating the second BWP;

3) the terminal starts or restarts the timer when receiving the first system information each time;

4) and the terminal stops the timer when successfully receiving the first system information.

For the counter, the terminal maintains the counter according to at least one of the following modes:

1) the terminal adds 1 to the count value of the counter every time the terminal receives the first system information;

2) the terminal adds 1 to the count value of the counter when receiving the first system information every time and receiving fails;

3) the terminal stops counting and resets a counting value when the second BWP is deactivated;

4) and when the terminal successfully receives the first system information, stopping counting and resetting a counting value.

In this way, the embodiment of the present invention may notify the network that the second BWP is activated when the active BWP of the terminal changes, or reactivate the first BWP after the first system information reception is completed, so that the network side and the terminal side can keep the activated BWPs consistent, thereby avoiding or reducing loss of data transceiving.

The above embodiments of the present invention are described in more detail below by way of several specific examples.

Example 1:

in this example 1, the terminal receives paging information, and the paging information notifies the UE that system information is updated. When the frequency range of the system information transmission is not within the frequency range of the currently activated BWP of the terminal, the terminal deactivates the currently activated BWP, activates a BWP (e.g., an Initial BWP) corresponding to the frequency range of the system information transmission, and receives system information on the BWP. In addition, the terminal also informs the network side that it transformed the active BWP on the newly active BWP:

step S11: the network sends paging information to inform the terminal of system information update (such as ETWS update).

Step S12: after the terminal receives the paging information, if the frequency range of the updated system information transmission notified by the paging information is not in the frequency range of the BWP currently activated by the terminal, the behavior of the terminal may include:

1) deactivating the currently activated BWP;

2) the paging message is activated to notify the updated BWP (e.g., Initial BWP) corresponding to the frequency range of the system information transmission.

Step S13: the terminal receives the paging information on the BWP activated in step S12, acquires updated system information from the paging information, and notifies the network side that it transforms the activated BWP on the BWP activated in step S12, in a manner including any one or more of the following manners:

mode 1: the terminal initiates a random access procedure on the BWP activated in step 2. Wherein the type of the random access procedure comprises one of: a contention random access procedure; a non-contention random access procedure.

Mode 2: the terminal sends an uplink signaling to notify a network side, wherein the uplink signaling comprises any combination of one or more of the following: RRC signaling (e.g., RRC messages), MAC signaling (e.g., MAC CE), and physical layer signaling (e.g., PUCCH indication information). Here, the content of the uplink signaling may include any combination of one or more of the following: an activated BWP identification, and a deactivated BWP identification.

Step S14: after receiving the notification in step S13, the network side performs corresponding signal transmission and reception, specifically including transmission and reception of uplink and downlink signals, on the BWP activated in step S12.

It should be noted that, in step S13, there is no strict execution order relationship between the received paging message and the BWP notifying the network side that the activation is changed, and the receiving may be performed in parallel, or one may be performed first and then the other.

Example 2:

in this example 2, when the terminal needs to initiate a service related to specific system information or performs a service related to the specific system information, when the frequency range of the system information transmission is not within the frequency range of the BWP currently activated by the terminal, the terminal deactivates the currently activated BWP, activates the BWP corresponding to the frequency range of the system information transmission (e.g., Initial BWP) and receives the system information on the BWP. In addition, the terminal also informs the network side that it transformed the active BWP on the newly active BWP:

step S21: when a terminal needs to initiate a service related to specific system information (e.g., needs to receive MBMS system information when initiating an MBMS service), if the frequency range in which the system information is transmitted is not in the frequency range of the BWP currently activated by the terminal, the behavior of the terminal may include:

1) deactivating the currently activated BWP;

Step S22: the terminal receives the system information on the BWP activated in step S22, and notifies the network side that it has transformed the activated BWP on the BWP activated in step S22 in the same manner as step S13 in example 1, which is not described herein again.

Step S23: after receiving the notification in step S22, the network side transmits and receives a corresponding signal to and from the terminal on the BWP activated in step S21.

Example 3:

in this example 3, the terminal receives the paging information, and the paging information notifies the UE that the system information is updated. When the frequency range of the system information transmission is not within the frequency range of the currently activated BWP of the terminal, the terminal notifies the network side that the currently activated BWP is transformed, then the terminal deactivates the currently activated BWP, activates the BWP corresponding to the frequency range of the system information transmission (e.g., Initial BWP) and receives the system information on the BWP:

step S31: the network sends paging information to inform the terminal of system information update (such as ETWS update).

Step S32: after receiving the paging information, if the paging information informs that the updated frequency range of system information transmission is not in the frequency range of the currently activated BWP of the terminal, the terminal transmits notification information on the currently activated BWP to notify the network side that it will change the activated BWP, where the notification method includes: and sending an uplink signaling to inform the network side. Wherein, the uplink signaling comprises any combination of one or more of the following: RRC signaling (e.g., RRC messages), MAC signaling (e.g., MAC CE), and physical layer signaling (e.g., PUCCH indication information or PRACH indication information). The content of the uplink signaling may include any combination of one or more of the following items: an activated BWP identification, and a deactivated BWP identification.

Step S33: after the terminal sends the notification to the network side in step S32, the behavior of the terminal may include:

1) deactivating the currently activated BWP;

Step S34: after receiving the notification information in step S32, the network side transmits and receives a corresponding signal to the terminal on the BWP activated in step S33.

Example 4:

in this example 4, when the terminal needs to initiate a service related to specific system information or performs a service related to the specific system information, when the frequency range of the system information transmission is not within the frequency range of the BWP currently activated by the terminal, the terminal notifies the network side that the active BWP is transformed on the currently activated BWP, then the terminal deactivates the currently activated BWP, activates the BWP (e.g., Initial BWP) corresponding to the frequency range of the system information transmission and receives the system information on the BWP:

step S41: when the terminal needs to initiate a service related to specific system information (e.g., needs to receive MBMS system information when initiating an MBMS service), if the frequency range in which the system information is transmitted is not in the frequency range of the currently activated BWP of the terminal, the terminal transmits a notification on the currently activated BWP informing the network side that it will change the activated BWP, in the same manner as in step S32 in example 3.

Step S42: after the terminal sends the notification to the network side in step S41, the behavior of the terminal may include:

1) deactivating the currently activated BWP;

2) the BWP corresponding to the frequency range of the system information transmission is activated (e.g., initial BWP).

Step S43: after receiving the notification in step S41, the network side transmits and receives a corresponding signal to and from the terminal on the BWP activated in step S42.

Example 5:

in this example 5, the terminal receives paging information, and the paging information notifies the UE that system information is updated. When the frequency range of the system information transmission is not within the frequency range of the currently activated BWP of the terminal, the terminal deactivates the currently activated BWP, activates the BWP corresponding to the frequency range of the system information transmission (e.g., the Initial BWP), and receives the system information on the BWP. After the terminal receives the system information, the terminal deactivates the BWP corresponding to the frequency range in which the system information is transmitted, and the terminal reactivates the previous BWP deactivated by receiving the system information:

step S51: the network sends paging information to inform the terminal of system information update (such as ETWS update).

Step S52: after the terminal receives the paging information, if the paging information informs that the frequency range of the updated system information transmission is not in the frequency range of the BWP currently activated by the terminal, the behavior of the terminal may include:

1) deactivating the currently activated BWP;

Step S53: the terminal receives the updated system information notified in the paging information on the BWP activated at step S52.

Step S54: after the terminal finishes receiving the system information (including successful reception or reception failure), the behavior of the terminal may include at least one of the following:

1) deactivating the BWP corresponding to the frequency range of the system information transmission (e.g., initial BWP);

2) the previously deactivated BWP is activated.

The method for the terminal to judge the end of the system information reception comprises at least one of the following steps:

1) a timer (TIMERx) times out;

2) a counter (counter) counting the number of attempts to receive the system information reaches or exceeds a preset threshold (corresponding to a preset maximum number of reception attempts).

The timeout time of the timer or the threshold value of the counter may be configured by the network side or agreed by a protocol.

Specifically, the maintenance mode of the timer includes any combination of one or more of the following:

1) the terminal starts the timer when receiving the system information for the first time;

2) the terminal starts the timer when the BWP corresponding to the system information is activated;

3) the terminal starts or restarts the timer each time the terminal receives the system information;

4) the terminal stops the timer when the system information is successfully received.

The maintenance method of the counter comprises any combination of one or more of the following steps:

1) the terminal adds 1 to the counter value when receiving the system information each time;

2) the terminal adds 1 to the counter value when receiving the system information and the system information fails to be received each time;

3) the terminal stops counting and resets when the BWP corresponding to the system information is deactivated;

4) the terminal stops counting and resets the counter when the system information is successfully received.

Example 6:

in this example 6, when the terminal needs to initiate a service related to specific system information or performs a service related to the specific system information, when the frequency range of the system information transmission is not in the frequency range of the BWP currently activated by the terminal, the terminal deactivates the currently activated BWP, activates the BWP corresponding to the frequency range of the system information transmission (e.g., Initial BWP) and receives the system information on the BWP. After the terminal receives the system information, the terminal deactivates the BWP corresponding to the frequency range in which the system information is transmitted, and the terminal reactivates the previous BWP deactivated by receiving the system information:

step S61: when the terminal is interested in receiving specific system information (e.g., MBMS system information), if the frequency range transmitted by the system information is not in the frequency range of the BWP currently activated by the terminal, the behavior of the terminal may include:

1) deactivating the currently activated BWP;

Step S62: the terminal receives the paging information on the BWP activated at step S62, and acquires updated system information.

Step S63: after the terminal successfully receives or fails to receive the system information, the behavior of the terminal may include at least one of:

1) the BWP corresponding to the frequency range of the system information transmission (e.g., the initial BWP) is deactivated.

2) The previously deactivated BWP is activated.

In this case, the terminal determines whether the system information reception is successful or failed, please refer to step S54 in example 5.
