Description

Partial carrier bandwidth BWP activation method and device and storage medium

Technical Field

The disclosure relates to the field of communications, and in particular, to a method and device for activating a partial carrier bandwidth BWP, and a storage medium.

Background

In a 5G (5 th Generation Mobile Communication Technology, fifth generation mobile communication technology) system, UEs (User Equipment) with different bandwidth reception capabilities are supported. To support UEs of different Bandwidth capabilities, the 3GPP (3 rd Generation Partnership Project, third generation partnership project) organization proposes the definition of BWP (Bandwidth Part, partial carrier Bandwidth). In order to save power consumption of the UE, the network side may configure the UE with BWP of different bandwidth lengths or different Numerology (parameter sets) according to the bandwidth receiving capability of the UE, where the BWP needs to be limited within the maximum receiving bandwidth of the UE. The UE or the network side can adaptively adjust the BWP according to the service requirement and the load condition of the UE, so as to save the power consumption of the UE and improve the transmission rate.

After the UE completes RRC (Radio Resource Control ) connection with the base station, the base station configures one or more BWP for the UE according to the traffic requirement of the UE. The BWP may be activated through RRC signaling or scheduling DCI (Downlink Control Information ), in which an index value indicating the BWP to be activated is indicated, and the UE activates its BWP according to the indication of the network side. However, this fixed configuration lacks flexibility.

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.

Before describing the BWP activation scheme provided in the present disclosure, the BWP activation scheme in the related art will be described.

In the related art, in the downlink direction, at most 4 BWPs may be configured for one UE per element carrier, but only one UE is in an active state at a time. The active BWP indicates an operation bandwidth used by the UE within the cell operation bandwidth, and outside the BWP, the UE does not receive PDSCH (Physical Downlink Shared Channel ), PDCCH (Physical Downlink Control Channel, physical downlink control channel) or CSI-RS (Channel State Information-Reference Signal, channel state information Reference Signal), but may be exceptional if used to make radio resource related measurements or transmit SRS (Sounding Reference Signal, channel sounding Reference Signal). Each downlink BWP includes at least one CORESET (Control-Resource Set) with a UE-specific search space, and the primary carrier includes at least one configurable downlink BWP with a CSS (Common Search Space ) of CORESET.

In the uplink direction, one UE may configure at most 4 BWPs per element carrier, but only one is in an active state at a time. If the UE employs uplink enhanced (SUL) technology, the UE may configure a maximum of 4 BWP on the SUL in addition, i.e., 8 BWP per unit carrier may be configured, but only one BWP may be activated at the same time. The UE does not transmit PUSCH (Physical Uplink Shared Channel ) or PUCCH (Physical Uplink Control Channel, physical uplink control channel) outside BWP. For the activated cells, the UE also does not transmit SRS outside the BWP.

Referring to fig. 1, it is assumed that the base station configures 3 different BWP for the UE, wherein the BWP1 has a bandwidth of 40MHz (megahertz), the SCS (Sub-Carrier Spacing) has a bandwidth of 15kHz (kilohertz), the BWP2 has a bandwidth of 10MHz, the SCS has a bandwidth of 15kHz, the BWP3 has a bandwidth of 20MHz, and the SCS has a bandwidth of 60kHz.

Wherein each PRB (Physical Resource Block ) occupies 12 subcarriers, and the larger the SCS interval, the fewer the number of PRBs in case of fixed bandwidth.

Initially, for example, in the period T1, the base station may configure the UE with an index value of 1 of BWP to be activated, where the corresponding bandwidth is 40MHz, and each PRB occupies 12×15 khz=180 kHz.

In case the base station determines that the traffic volume of the UE is reduced, for example, in the T2 period, the base station may inform the UE to activate BWP with index value of 2, where the corresponding bandwidth is 10MHz, and each PRB occupies 180kHz. The UE uses lower bandwidth during this period, and the power consumed by the UE decreases.

In case of an increase in UE traffic, for example, in the T3 period, the base station may inform the UE to activate BWP with index value 3.

It can be seen that the network-side device, e.g. the base station, needs to send DCI or RRC signaling for scheduling to the UE, where the DCI or RRC signaling for scheduling includes an index value of the BWP to be activated, indicating that the UE activates the corresponding BWP. The above processes are initiated by the network side equipment and are ended based on the expected behavior of the network side equipment, and are irrelevant to the own expectation of the UE. Resulting in a BWP activated at the UE side may not be the most appropriate BWP.

To solve this technical problem, the present disclosure provides the following BWP activation scheme.

Fig. 2 is a flowchart of a partial carrier bandwidth BWP activation method according to an exemplary embodiment of the present application, which is described from the UE side, where the UE includes, but is not limited to, a mobile phone, a notebook computer, a desktop computer, an ipad, and other terminals, and as shown in fig. 2, the partial carrier bandwidth BWP activation method includes:

In step 201, a first index value of a first BWP to be activated, which is transmitted by a base station, is received.

In step 202, a second index value of a second BWP that the UE desires to activate is determined.

In the embodiment of the present disclosure, the UE may determine, according to its own service requirement, a second index value of a second BWP that the UE desires to activate.

In step 203, the second index value is reported to the base station in response to determining that the second index value is different from the first index value.

In step 204, the first BWP or the second BWP is activated based on the target indication information transmitted by the base station.

In an embodiment of the present disclosure, the target indication information is used to indicate whether the base station agrees to the UE to activate the second BWP.

In the above embodiment, the UE side behavior and the network side behavior may be combined, and the most appropriate BWP is selected for activation from the first BWP to be activated and the second BWP that the UE itself expects to activate, which are determined by the base station for the UE, so that flexibility and availability in activating the BWP are improved.

In some alternative embodiments, for the step 201, the base station may send the first index value to the UE through DCI or RRC signaling, and the UE may directly receive the first index value.

In some alternative embodiments, for step 202 above, the UE may determine one BWP that meets the UE service requirement among the BWP of the plurality of BWP preconfigured for the UE by the base station. Any two of the BWP types correspond to different bandwidths and/or different subcarrier spacings, for example, the UE may determine one BWP type meeting its own traffic requirement among the 3 BWP types shown in fig. 1.

Further, the UE determines an index value of the BWP meeting the UE traffic demand as the second index value.

In one possible implementation, the UE may wish to save power for a period of time even if there is a large amount of data generated, e.g., the UE just started an APP (Application) and has the corresponding data to download, but the UE enters a power saving mode due to insufficient power, etc. At this time, the UE selects an index value of BWP capable of satisfying the large-traffic data as the second index value.

In one possible implementation, the UE may wish to keep the bandwidth selection high for a period of time, even if the amount of data actually generated is not large, for example, the UE enters a game APP and is expected to occupy the high bandwidth, but it is possible that only the data already buffered by the UE needs to be read during a certain period of time of the game, and the amount of data generated by the network side is not large. At this time, the UE selects an index value of BWP with a larger bandwidth as the second index value.

In another possible implementation, the UE classifies its BWP, which is more desirable to combine the resources of the network from the traffic demand of the UE itself, so that the index value of the corresponding BWP is taken as the second index value.

In the above embodiment, the UE may determine, according to its own service requirement, the second index value of the second BWP that the UE desires to activate from the service level, which is simple to implement and has high availability.

In some alternative embodiments, in the case that the second index value is different from the first index value, the UE may report the second index value of the second BWP to the base station through UCI (Uplink Control Information ) in step 203. Wherein, UCI is carried through PUCCH.

In the above embodiment, the UE may report, to the base station, the second index value that the UE desires to activate through UCI, if the second index value of the second BWP that the UE desires to activate is different from the first index value of the first BWP to be activated, which is sent by the base station. So that the base station determines whether to agree to activate the second BWP by the UE, thereby achieving the purpose of selecting the most appropriate BWP for activation later, and having high availability.

In some alternative embodiments, for the above step 204, if it is determined that the base station does not agree to activate the second BWP by the UE or that the UE is desired to activate according to the network side configuration, based on the target indication information, the UE may activate the first BWP directly according to the information previously configured by the base station. If it is determined that the base station agrees to the activation scheme of the UE, i.e., agrees to the UE to activate the second BWP, based on the target indication information, the UE may activate the second BWP.

In one possible implementation, if the bit value of the information bit in which the target indication information is located is a first preset value, the UE determines that the base station does not agree to activate the second BWP by the UE, or the UE wants to activate according to the network side configuration, and the UE activates the first BWP. Wherein, the first preset value may be 0 or 1, which is not limited in the present disclosure.

If the bit value of the information bit where the target indication information is located is a second preset value, the UE determines that the base station agrees that the UE activates the second BWP, and the UE activates the second BWP. The second preset value is different from the first preset value, and when the first preset value is 0, the second preset value can be 1, whereas when the first preset value is 1, the second preset value can be 0.

In the above embodiment, after the UE reports the second index value to the base station, the UE selects and activates the first BWP or the second BWP based on the bit value of the information bit where the target indication information sent by the base station is located, so as to achieve the purpose of jointly selecting the most appropriate BWP for activation by combining the UE side behavior and the network side behavior, and the availability is high.

In some alternative embodiments, referring to fig. 3, fig. 3 is another method for activating a partial carrier bandwidth BWP according to an embodiment, where the method may include:

In step 301, a first index value of a first BWP to be activated, which is transmitted by a base station, is received.

In step 302, a second index value of a second BWP that the UE desires to activate is determined.

In step 303, the second index value is reported to the base station in response to determining that the second index value is different from the first index value.

In step 304, the first BWP or the second BWP is activated based on the target indication information transmitted by the base station.

The implementation of steps 301-304 is similar to the implementation of steps 201-204 described above, and will not be repeated here.

In step 305, the first BWP is activated in response to determining that the second index value is the same as the first index value.

In the embodiment of the present disclosure, if the first index value of the first BWP to be activated, which is indicated by the base station, is the same as the second index value of the second BWP that the UE desires to activate, the UE may directly activate the first BWP.

In the above embodiment, the UE may directly activate the first BWP under the condition that the first index value of the first BWP to be activated indicated by the base station is the same as the second index value of the second BWP that the UE desires to activate, which also implements the purpose of selecting the most appropriate BWP to activate by combining the UE-side behavior and the network-side behavior through a negotiation manner, thereby improving flexibility and high availability when activating the BWP.

The BWP activation scheme provided by the present disclosure will be described from the base station side.

Fig. 4 is a flowchart of a partial carrier bandwidth BWP activation method according to an exemplary embodiment of the present application, which is described from the base station side, and as shown in fig. 3, the partial carrier bandwidth BWP activation method includes:

in step 401, a first index value of a first BWP to be activated is determined for the user equipment UE.

In step 402, the first index value is sent to the UE.

In step 403, in response to receiving the second index value reported by the UE, it is determined whether the UE is agreed to activate the second BWP.

Wherein the second index value is an index value of a second BWP that the UE desires to activate, and the second index value is different from the first index value.

In step 404, target indication information is sent to the UE.

The target indication information is used to indicate whether the base station accepts the UE to activate the second BWP.

In the above embodiment, the base station may determine whether to agree to activate the second BWP by using the second index value reported by the UE, and send the target indication information to the UE, so as to achieve the purpose of selecting the most appropriate BWP for activation based on the UE side behavior and the network side behavior, thereby improving flexibility in activating the BWP.

In some alternative embodiments, for step 401 described above, the base station may determine the first index value using a related technique, including, but not limited to, determining the index value of the BWP to be activated in the embodiment shown in fig. 1.

In some alternative embodiments, for step 402 described above, the base station may send the first index value to the UE through DCI for scheduling, or RRC signaling.

In some optional embodiments, for the step 403, optionally, the base station may determine the remaining bandwidth in combination with the current load and the bandwidth corresponding to the different load, and determine not to accept the UE to activate the second BWP if the remaining bandwidth is determined to be smaller than the bandwidth corresponding to the second BWP, otherwise, determine to agree to activate the second BWP if the remaining bandwidth is determined to be greater than or equal to the bandwidth corresponding to the second BWP.

In the above embodiment, after receiving the second index value reported by the UE, the base station may determine, in combination with the actual available resources on the network side, whether to agree to activate the second BWP meeting the service requirement of the UE. The implementation is simple and convenient, the flexibility in the BWP activation process is improved, and the availability is high.

In some optional embodiments, the base station may determine, when determining that the UE is not authorized to activate the second BWP, a bit value of an information bit in which the target indication information is located as the first preset value. Alternatively, the first preset value may be 0 or 1, which is not limited by the present disclosure. The base station may inform the UE that the base station does not agree to activate the second BWP by setting a bit value of an information bit where the target indication information is located to a first preset value, that is, it is desirable that the UE performs BWP activation based on a configuration provided before the network side.

And when the base station determines that the UE is agreed to activate the second BWP, determining the bit value of the information bit where the target indication information is located as a second preset value. Alternatively, the second preset value is different from the first preset value, and when the first preset value is 0, the second preset value may be 1, or when the first preset value is 1, the second preset value may be 0. The base station may inform the UE that the base station agrees to the UE to activate the second BWP, that is, allow the UE to activate the second BWP meeting its own expectations, by setting a bit value of an information bit where the target indication information is located to a second preset value.

In the above embodiment, the base station may inform the UE whether the base station agrees to activate the second BWP by setting the bit value of the information bit where the target indication information is located to different preset values, which is simple and convenient to implement and has high availability.

In some alternative embodiments, the base station may send the target indication information to the UE through DCI or RRC signaling for step 404 described above. In one possible implementation, the base station may add an information bit corresponding to the target indication information in DCI or RRC signaling, and inform the UE whether the base station agrees to activate the second BWP by setting the information bit to a different preset value.

So that the UE may activate the first BWP or the second BWP after receiving the target indication information.

In the above embodiment, the UE needs and network resources at the base station side may be combined, and the most appropriate BWP may be selected for activation, so that the availability is high.

In some alternative embodiments, the base station may also perform the following step 405 (not shown in fig. 4) after performing step 304 described above:

in step 405, in response to determining that the base station agrees to the UE to activate the second BWP, bandwidth resources corresponding to the second BWP are configured for the UE.

In the embodiment of the disclosure, the base station configures the corresponding bandwidth resource for the UE based on the second BWP that the UE desires to activate.

In the above embodiment, after the base station transmits the first index value to the UE, the base station may configure the resources corresponding to the second BWP for the UE through negotiation between the UE and the base station, so as to achieve the purpose of activating and using the most appropriate BWP.

It should be further noted that, when configuring the bandwidth resource and/or subcarrier spacing information corresponding to the second BWP for the UE, the base station may configure the bandwidth resource exceeding the previously preconfigured bandwidth resource corresponding to the second BWP, but not exceeding the upper limit of the available resources of the base station. For example, the bandwidth resource corresponding to the second BWP is 20MHz, the base station has accessed 10 other UEs, the bandwidth provided for each UE is 100MHz, but the remaining bandwidth is only 30MHz, and then the base station cannot configure bandwidth resources exceeding the remaining bandwidth for the UE.

In some alternative embodiments, fig. 5 is a flowchart of a method for activating a partial carrier bandwidth BWP according to an exemplary embodiment of the present application, and as shown in fig. 5, the method for activating the partial carrier bandwidth BWP includes:

in step 501, the base station determines a first index value of a first BWP to be activated for the user equipment UE.

In step 502, the base station sends the first index value to the UE.

In step 503, the UE determines a second index value of a second BWP that is desired to be activated.

The UE performs step 504 if it is determined that the second index value is different from the first index value, otherwise performs step 509.

In step 504, the UE determines that the second index value is different from the first index value, and reports the second index value to the base station.

In step 505, the base station determines whether the UE is agreed to activate the second BWP.

In step 506, the base station transmits target indication information to the UE.

If the UE determines that the bit value of the information bit where the target indication information is located is the first preset value, step 507 is executed, otherwise step 508 is executed.

In step 507, the UE determines a bit value of an information bit where the target indication information is located as a first preset value, and activates the first BWP.

In step 508, the UE determines a bit value of the information bit where the target indication information is located as a second preset value, and activates the second BWP.

In step 509, the UE determines that the second index value is the same as the first index value, and activates the first BWP.

In the above embodiment, after the UE negotiates with the base station, the optimal BWP is selected to be activated in combination with the service requirement of the UE and the network actual resource at the base station side, so that the flexibility in activating the BWP is improved, and the availability is high.
