Description

User equipment, method of deactivating BWP thereof, and computer-readable storage medium

Technical Field

Embodiments of the present invention relate to the field of communications, and in particular, to a user equipment, a BWP deactivation method thereof, and a computer-readable storage medium.

Background

With the continuous development of wireless communication technology, 3GPP introduced 5G New Radio (NR) technology, following 3G and 4G. In the NR system, the maximum channel bandwidth per carrier is 400 MHz. The concept of fractional Bandwidth (BWP) was introduced because a fractional User Equipment (UE) may not be able to support 400MHz of Bandwidth and in view of power consumption requirements. For each carrier, the base station may configure one or more BWPs for the UE. The UE may communicate using a different BWP by activating/deactivating the BWP. BWPs are classified into Uplink (UL) BWPs and Downlink (DL) BWPs.

There are currently two implementations of activation/deactivation BWP: 1. the base station instructs the UE to activate/deactivate BWP through dedicated Radio Resource Control (RRC) signaling or Downlink Control Information (DCI). 2. The UE starts a timer for the different BWPs and switches the Active DL BWP to the default DL BWP after the timer expires, which may be the Initial Active DL BWP. The initial active BWP is the BWP of the UE at initial access.

For active BWP, the current implementation scheme either needs to wait for the base station to notify the UE to deactivate the BWP, which causes extra signaling overhead, or waits for the timer of the UE to time out before deactivating the BWP, which results in increased power consumption of the UE.

Detailed Description

In NR systems, current BWP deactivation schemes either require the base station to instruct the user equipment to activate/deactivate BWP through dedicated RRC signaling or DCI, or require starting a timer for DL BWPs other than the default DL BWP and deactivating the BWP when the timer expires. For active BWP, the current implementation scheme either needs to wait for the base station to notify the ue to deactivate the BWP, which causes extra signaling overhead, or waits for the timer of the ue to time out before deactivating the BWP, which cannot deactivate the BWP in time, resulting in increased power consumption of the ue.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 1, an embodiment of the present invention provides a method for deactivating BWP by a user equipment, where the method may include the following steps:

step S101, after releasing the logical channel, determining whether the BWP in the active state does not correspond to any logical channel.

In a specific implementation, for a connected user equipment, a base station may configure multiple active BWPs and multiple logical channels for service. One logical channel may be mapped to multiple BWPs or one BWP. And after receiving the RRC signaling for releasing the logical channel, the user equipment executes normal logical channel release processing. After the releasing logical channel processing is completed, it is determined whether the BWP in the active state does not correspond to any logical channel, because not corresponding to any logical channel means that there is no more data transmission, and thus it is not necessary to be in the active state, so it is first determined whether the BWP in the active state does not correspond to any logical channel.

Step S102, when there is an active state BWP which does not correspond to any logical channel, deactivating or directly releasing the BWP.

In a specific implementation, when there is an active BWP that does not correspond to any logical channel, the BWP is selected to be deactivated or released directly. Not corresponding to any logical channel means that there is no more data transmission, and at this time, the BWP is deactivated or directly released, so that the BWP without any data transmission can be timely deactivated without increasing additional signaling overhead.

In particular implementations, BWP may also be deactivated based on a channel quality corresponding to the BWP. When the channel quality corresponding to the BWP is poor, normal data transmission cannot be performed, and the BWP may be deactivated or directly released, so as to avoid that the subsequent base station sends additional signaling to perform deactivation or direct release, thereby further saving signaling overhead.

In an embodiment of the present invention, a channel quality corresponding to a synchronization signal of the active BWP is detected; when detecting that the channel quality corresponding to the synchronization signal of any one BWP meets a preset condition, deactivating or directly releasing the BWP.

In a specific implementation, the channel quality corresponding to the synchronization Signal of the BWP may be determined according to a Reference Signal Receiving Power (RSRP), which is an average value of Signal powers received on all Resource Elements (REs) carrying the Reference Signal within a certain symbol and may be used to represent the strength of the wireless Signal. The channel Quality corresponding to the BWP synchronization Signal may also be determined according to Reference Signal Receiving Quality (RSRQ), which is the ratio of RSRP to the received power of all signals in the cell.

In a specific implementation, the preset condition that the channel quality meets may be that RSRP is lower than a preset receiving power threshold, or that RSRQ is lower than a preset receiving quality threshold.

In a specific implementation, after the user equipment deactivates the BWP based on the channel quality corresponding to the BWP, the user equipment may notify the base station of the deactivated or released BWP in order to avoid the subsequent base station sending additional signaling to deactivate the BWP.

In an embodiment of the present invention, after the deactivating or directly releasing the BWP when the channel quality corresponding to the synchronization signal of any BWP is detected to satisfy the preset condition, the method further includes: sending indication information to a base station, wherein the indication information comprises: the BWP that has been deactivated or has been released directly.

In a specific implementation, the indication information may be sent via RRC signaling.

In particular implementations, BWPs may be grouped and maintained with one deactivation timer for each group of BWPs, e.g., using the same deactivation timer for BWPs having the same number of contexts, due to the higher number of timers maintained by the user device and the higher memory overhead for maintaining separate deactivation timers for different BWPs. The numerology defines a set of parameters for the 5G system, including subcarrier spacing, Cyclic Prefix (CP) type, etc. Maintaining one deactivation timer for each set of BWPs may reduce the number of deactivation timers maintained by the user equipment, thereby reducing processing complexity.

In a specific implementation, the base station may indicate the way of the user equipment BWP grouping in advance through an RRC signaling manner, for example, the base station may indicate BWPs with the same numerology as a same group BWP or notify the user equipment of information of each specific group BWP, and the user equipment starts a same deactivation timer for each group BWP based on the information indicated by the base station.

In an embodiment of the present invention, the group indication information of BWP sent by the base station through RRC signaling may be received; starting the same deactivation timer for the same group of BWPs in the activated state; restarting the deactivation timer if downlink control signaling is received through any one of the BWPs of the same group of BWPs or data is transmitted through any one of the BWPs of the same group of BWPs before the deactivation timer expires; deactivating or directly releasing the same group of BWPs upon expiration of the deactivation timer.

In an embodiment of the present invention, the grouping may include: numerology attribute, BWPs with the same numerology attribute are the same group BWP.

In a specific implementation, the data transmitted by any BWP of the same group may be uplink data transmitted by any BWP of the same group, or downlink data received by any BWP of the same group, or both uplink data transmitted by any BWP of the same group and downlink data received by any BWP of the same group.

In an embodiment of the present invention, the base station instructs, through RRC signaling, the user equipment to configure BWP0, BWP1 and BWP2, where BWP0 is initial activation BWP, BWP1 and BWP2 are the same group BWP, and the corresponding deactivation timer duration is 200 ms. After receiving the configured RRC signaling, the ue starts a timer T1 with a duration of 200ms for BWP1 and BWP 2. Before the time-out of T1, if downlink control signaling is received, downlink data is received, or uplink data is transmitted from BWP1 or BWP2, T1 is restarted. When T1 times out, BWP1 and BWP2 are deactivated.

By applying the above scheme, after the logical channel is released, it is firstly determined whether there is a BWP not corresponding to any logical channel, and then when there is an active BWP not corresponding to any logical channel, the BWP is actively deactivated or directly released, so that the BWP without any data transmission can be timely deactivated without increasing extra signaling overhead, and the power consumption of the user equipment is reduced.

In order to make the present invention better understood and implemented by those skilled in the art, another method for deactivating BWP by a user equipment is provided in the embodiment of the present invention, as shown in fig. 2.

Referring to fig. 2, the method for deactivating BWP by the user equipment may include the steps of:

step S201 detects the channel quality corresponding to the synchronization signal of the active BWP.

In specific implementation, when the channel quality corresponding to the BWP is poor, normal data transmission cannot be performed, the BWP may be deactivated or directly released, so as to avoid that a subsequent base station sends an additional signaling to perform deactivation or direct release, thereby further saving signaling overhead.

Step S202, when detecting that the channel quality corresponding to the synchronization signal of any one BWP meets the preset condition, deactivating or directly releasing the BWP.

In a specific implementation, the channel quality corresponding to the synchronization signal of the BWP may be determined according to RSRP, which is an average value of signal powers received on all REs carrying the reference signal within a certain symbol and may be used to indicate the strength of the wireless signal. The channel quality corresponding to the BWP synchronization signal may also be determined according to RSRQ, which is the ratio of RSRP to the received power of all signals in the cell.

In a specific implementation, the condition that the channel quality meets the preset condition may be that RSRP is lower than a preset receiving power threshold, or that RSRQ is lower than a preset receiving quality threshold.

By applying the above scheme, for the BWP with poor channel quality corresponding to the synchronization signal, the user equipment actively deactivates or directly releases in time, which can avoid the subsequent base station from sending extra signaling to deactivate, and further save signaling overhead.

In order to make those skilled in the art better understand and implement the present invention, another method for deactivating BWP by a user equipment is provided in the embodiment of the present invention, as shown in fig. 3.

Referring to fig. 3, the method for deactivating BWP by the user equipment may include the steps of:

step S301, receiving BWP packet indication information sent by the base station through RRC signaling.

In particular implementations, BWPs may be grouped and maintained with one deactivation timer for each group of BWPs, e.g., using the same deactivation timer for BWPs having the same number of contexts, due to the higher number of timers maintained by the user device and the higher memory overhead for maintaining separate deactivation timers for different BWPs. The set of parameters defined by numerology for the 5G system may include subcarrier spacing, Cyclic Prefix (CP) type, etc. Maintaining one deactivation timer for each set of BWPs may reduce the number of deactivation timers maintained by the user equipment, thereby reducing processing complexity.

In a specific implementation, the base station may indicate the BWP grouping manner of the user equipment in advance through an RRC signaling manner. For example, the base station may indicate BWPs having the same numerology to be the same group of BWPs or inform the user equipment of information of specific each group of BWPs, and the user equipment starts the same deactivation timer for each group of BWPs based on the information indicated by the base station.

In step S302, the same deactivation timer is started for the same group of BWPs in the activated state.

Step S303, before the deactivation timer expires, if a downlink control signaling is received through any BWP of the same group of BWPs or data is transmitted through any BWP of the same group of BWPs, restarting the deactivation timer.

Step S304, after the deactivation timer expires, deactivating or directly releasing the same group of BWPs.

By applying the above scheme, by grouping BWPs and starting the deactivation timer for each group of BWPs, the number of deactivation timers maintained by the user equipment can be reduced, thereby reducing processing complexity.
