Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.

In order to solve the above-mentioned problems, the present embodiment provides indication information and an indication command regarding BWP handover, which facilitate the base station to flexibly indicate whether the UE performs BWP handover.

Fig. 1 is a flow chart illustrating a method of bandwidth part switching for an access network device such as a base station according to an exemplary embodiment. As shown in fig. 1, the method includes the following steps 101-102.

In step 101, when a preset trigger condition is satisfied, indication information about bandwidth part (BWP) switching is generated.

In step 102, an indication command regarding BWP handover is sent to the user equipment, the indication command carrying the indication information.

The triggering condition in this embodiment affects the active state of the UE, and the triggering condition that causes the UE to transition to the inactive direction is applicable to this embodiment. When the preset trigger condition is met, the UE may be instructed to perform BWP handover, i.e., to the UE carrying the low active state.

The active state may be divided into an active state, an inactive state and an idle state according to the UE state, and the corresponding active state is from high to low. Or according to the traffic division, whether the UE is in an active state or in an inactive state, the traffic and the frequency of the interaction with the network side are divided into high and low fractions, and the active state can be divided according to the interaction traffic and the frequency, wherein the larger the traffic is, the higher the frequency is, the higher the corresponding active state is, and otherwise the lower the corresponding active state is.

UEs in different active states may be carried by different BWP's in order to better serve the UE. The present embodiment may indicate whether the UE performs BWP handover according to a change in the active state of the UE. Flexible configuration of BWP switching is achieved.

In one embodiment, the trigger condition includes at least one of:

configuring DRX;

a sleep (GTS) signal is generated.

In this embodiment, when the UE enters the DRX off period from the DRX (discontinuous reception) on period, the UE transitions from the current active state to the opposite inactive state. The base station knows the time domain distribution of the DRX on period and the DRX off period in advance, so the UE can be notified by an indication command in consideration of whether the UE needs to perform BWP handover when configuring DRX.

The base station may send a GTS signal to the UE according to the service condition of the UE, where the GTS signal may instruct the UE to enter a dormant state, that is, instruct the UE to transition to an inactive direction. At this time, the base station may inform the UE by an indication command considering whether the UE needs to perform BWP handover.

Other trigger conditions that affect the active state of the UE may also be applicable to this embodiment. The base station may transmit the trigger condition to the UE through dedicated signaling, such as RRC (radio resource control) signaling.

In one embodiment, the indication information includes at least one of: an indication bit, a first duration, and a second duration;

when the value of the indicating bit is a second value, the BWP switching is indicated; when the value of the indicating bit is a first value, indicating that the current BWP resides;

the first duration is used for indicating that the current BWP resides in the first duration;

the second duration is used for indicating that BWP switching is performed when the second duration is not smaller than a preset duration threshold.

The instruction command may only carry an instruction bit, and the instruction bit may occupy 1bit (bit), for example, the second value is 1, and the first value is 0; alternatively, the second value is 0 and the first value is 1. When the value of the indication bit is the second value, the UE immediately performs the BWP handover after receiving the indication command. When the value of the indication bit is the first value, the UE resides in the current BWP after receiving the indication command, and does not perform the BWP handover until receiving the indication command again. In this embodiment, the base station may instruct the UE to switch immediately or not through the indication bit. A more direct indication command is provided.

In this embodiment, the instruction command may only carry the first time length. After receiving the indication command, the UE resides in the current BWP in the first time period, and does not perform the BWP handover. After the first time period is exceeded, whether the BWP is switched or not is judged according to the existing strategy. In this embodiment, the base station may instruct the UE to not perform BWP switching within a certain duration through the first duration, which provides an effective duration for not performing BWP switching, and also provides a feasible scheme for supporting not performing BWP switching.

In this embodiment, the instruction command may only carry the second duration. After receiving the instruction command, the UE determines whether the second duration is not less than a preset duration threshold, and performs BWP handover when the second duration is not less than the preset duration threshold, otherwise, the UE resides in the current BWP. The duration threshold is a known constant in this embodiment. The base station may control whether the UE performs the BWP handover by configuring the second duration.

The indication information in this embodiment further includes: duration of time;

That is, the indication bit may be further combined with the first duration and the second duration, and when the value of the indication bit is the second value, the indication information includes a duration of the second duration. Firstly, the indicator bit is a second value to allow the UE to perform BWP switching, and secondly, the UE determines whether to perform BWP switching finally according to the judgment of the second duration and the duration threshold. When the value of the indication bit is a first value, the indication information includes a duration of a first duration. The indication bit having the first value indicates that the UE is not allowed to perform BWP handover, and the effective duration of the BWP handover is defined by the first duration.

In one embodiment, when configuring DRX, the value of the indication bit is a first value, which indicates that the UE resides in the current BWP, and may also carry a first time length, which indicates that the UE resides in the current BWP in the first time length.

In this embodiment, when DRX is configured, BWP switching may not be performed during the DRX off period. During DRX off, since the UE is in an inactive state at this time, BWP handover is unnecessary, which may reduce redundant BWP handover processing.

In one embodiment, the indication command includes a GTS signal.

In this embodiment, the GTS signal may be used as an indication command, that is, the UE determines whether to perform BWP handover according to the indication of the GTS signal. The GTS signal instructs the UE to enter a dormant state, i.e., transition to an inactive direction, the UE may consider switching BWP.

In one embodiment, the second duration is a sleep duration.

When the GTS signal is used as the indication BWP switch command, the sleep duration carried by the GTS signal may be used as the second duration. And when the sleep time length is not less than the preset time length threshold value, the UE can perform BWP switching. In contrast, the BWP switching is not performed, so that the resource consumption of the UE by redundant BWP switching is reduced.

In one embodiment, the first duration is a sleep duration.

When the GTS signal is taken as an indication that the BWP switch command is not performed, the sleep duration carried by the GTS signal may be taken as the first duration. Since the UE is in an inactive state at this time, BWP handover is unnecessary, which may reduce redundant BWP handover processing.

The indication information in this embodiment may further include identification information of the target BWP, and the base station may inform the UE of which target BWP to switch to by the indication command, enabling flexible configuration of the target BWP.

The implementation process of the base station side is described above, and correspondingly, the UE side is improved, and the implementation process of the UE side is described below.

Fig. 2 is a flow chart illustrating a method of bandwidth part switching for a user device, which may be a mobile phone, a computer, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, an exercise device, a personal digital assistant, etc., according to an exemplary embodiment. As shown in fig. 2, the method includes the following steps 201-202.

In step 201, an indication command about BWP handover sent by a base station is received, where the indication command carries the indication information.

In step 202, it is determined whether to perform a BWP handover according to the indication information.

The present embodiment adds instruction information and instruction commands for indicating whether or not to perform a handoff of BWP. The UE may receive and execute the indication command, and perform a BWP handover or camp on the current BWP under the indication of the indication command. Flexible configuration of BWP is achieved.

In one embodiment, the indication information includes: indicating a bit.

The step 202 includes: step A1-step A2.

In step A1, when the value of the indicator bit is the second value, the BWP is switched.

In step A2, when the value of the indicator bit is the first value, the current BWP is resident.

In this embodiment, the UE may immediately perform BWP handover according to the indication of the indication bit, or reside in the current BWP to implement BWP handover immediately, and also support BWP to remain unchanged.

In one embodiment, when the value of the indication bit is a first value, the indication information includes: a first duration.

The step 202 includes: and (B) a step of.

In step B, the current BWP is resident for said first duration.

In this embodiment, the UE resides in the current BWP in the effective duration according to the indication of the first duration, keeps the BWP unchanged, and reduces frequent and redundant BWP switching.

In one embodiment, when the value of the indication bit is the second value, the indication information includes: a second time period.

The step 202 includes: step C1-step C3.

In step C1, it is determined whether the second duration is not less than a preset duration threshold.

In step C2, when the second duration is not less than the preset duration threshold, a BWP is switched.

In step C3, when the second duration is less than a preset duration threshold, the current BWP is resided.

In this embodiment, a time length threshold value, which is a known constant, is preconfigured. And the UE compares the received second time length with a time length threshold value, and if the received second time length is not smaller than the preset time length threshold value, the BWP is switched, and otherwise the UE resides in the current BWP. The base station may control whether the UE performs the handover of the BWP by configuring the length of the second duration.

In one embodiment, the preset duration threshold includes one of the following:

The duration threshold may be configured in this embodiment with reference to a number of factors, such as with reference to the duration required for one BWP handover, to ensure that one BWP handover may be completed within the second duration, otherwise no BWP handover is performed, reducing redundant BWP handovers. For another example, the duration threshold is configured with reference to the duration required for the secondary BWP handover to ensure that the UE can switch to the target BWP and back to the current BWP, giving the BWP handover sufficient duration, otherwise no BWP handover is performed, reducing redundant BWP handover. For another example, the duration threshold is configured with reference to a sum of a duration required for one BWP handover and a preset reference duration to ensure that at least one BWP handover can be completed within the second duration, otherwise no BWP handover is performed, reducing redundant BWP handovers.

In one embodiment, the indication command includes a GTS signal.

In one embodiment, the second duration is a sleep duration.

When the GTS signal is used as the indication BWP switch command, the sleep duration carried by the GTS signal may be used as the second duration. The sleep time period means a time period during which the UE is in an inactive state, and the sleep time period ends, so that the UE may be transitioned to an active state. If the sleep duration is shorter and less than the duration threshold, a BWP handoff may not be performed, reducing the equipment and network resources consumed by frequent BWP handoffs. If the sleep duration is longer, not less than the duration threshold, a handoff of BWP may be performed.

In one embodiment, the first duration is a sleep duration.

In one embodiment, the step A1 and the step C2 include: step E1-step E3.

In step E1, switching to the next BWP corresponding to the current BWP; wherein the activity level of the next level BWP is lower than the current activity level of BWP.

In this embodiment, when determining that the UE transitions to the inactive direction, the base station sends an indication command to the UE, indicating the UE to switch BWP. The UE switches to the next stage BWP according to the indication of the indication command. The active level of the UE of the next level BWP service is lower than the active level of the UE of the current BWP service. The UE may be pre-configured with multi-level BWP and may be self-handed off to the next level BWP.

In step E2, a switch is made to the target BWP indicated by the system information received in advance.

In this embodiment, the base station may send the target BWP to the UE through the system information in advance. The UE switches to the target BWP according to the indication of the indication command, and the target BWP is not limited to the next-stage BWP. The base station is convenient to flexibly configure the target BWP.

In step E3, switching to the target BWP indicated by the indication information.

In this embodiment, the base station may send the target BWP to the UE along with the indication command, and the target BWP is not limited to the next stage BWP, so that the configuration of the target BWP is more flexible.

In this embodiment, each cell has an initial BWP, and when the cell is initially accessed, the cell resides in the initial BWP. The present embodiment takes the initial BWP as the BWP with a lower activity level.

Each cell is configured with a default BWP, which may be an initial BWP or other BWP. The present embodiment takes the default BWP as the BWP with the lower active level.

The present embodiment may also fixedly configure one target BWP as the BWP with a lower activity level.

In one embodiment, the method further comprises: and F, step F.

In step F, upon expiration of the BWP inactivity timer, the BWP is masked from switching over of BWP triggered by the BWP inactivity timer expiration.

The BWP inactivity timer (BWP inactivity timer) triggers a BWP switch upon timeout. The BWP inactivity timer may be restarted when the UE has communication interaction with the base station. The embodiment controls whether the UE performs BWP handover by the indication information and the indication command, and if not, the UE may not be controlled by the BWP inactivity timer, and mask the BWP handover triggered by the BWP inactivity timer timeout.

If the UE does not perform BWP handover and the first time period is given, this means that the BWP handover triggered by the expiration of the mask BWP inactivity timer takes effect in the first time period.

The implementation is described in detail below by way of several embodiments.
