Description

Method and apparatus for adjusting filter

Technical Field

The embodiment of the application relates to the technical field of wireless communication, in particular to a method and equipment for adjusting a filter.

Background

Currently, for a New air interface unlicensed spectrum (New Radio-Unlicensed Spectrum, abbreviated as NR-U) system, a third generation partnership project standard organization (3 rd Generation Partnership Project, abbreviated as 3 GPP) defines a listen-before-talk (Listen Before Talk, abbreviated as LBT) mechanism, which agrees that a data sender needs to listen before using a spectrum, and confirms that the spectrum is idle before using the spectrum.

In an NR-U system, a network device or User Equipment (UE) typically performs LBT with a bandwidth of 20 MHz. However, in the case of a wide Band (BWP), for example, the bandwidth of the system is 80MHz, when the bandwidth of each Resource Block-set (RB-set) of the system bandwidth is 20MHz, there are 4 RBs-sets to perform LBT in parallel, and when there are RBs-sets that do not successfully perform LBT, if the UE still uses a filter of the bandwidth of 80MHz to receive data, the RB-set that does not successfully perform LBT affects the reception of data by the UE. Therefore, when there is an RB-set that does not successfully perform LBT in BWP, the filter of the UE needs to be further adjusted to avoid the RB-set that does not successfully perform LBT from affecting the UE to receive data.

However, since the filter is not able to receive data during the adjustment period, if the network device transmits data to the UE during the adjustment period of the filter by the UE, the UE cannot receive the data, and thus data loss is likely to occur.

For example, in some embodiments, the network device 102 sends a message to the UE101; after receiving the message, the UE101 performs the corresponding task item based on the notification message. The following will explain in detail the embodiments.

The embodiment of the application provides a method for adjusting a filter, which is applied to UE. Referring to fig. 2, fig. 2 is a flowchart illustrating a method for adjusting a filter according to an embodiment of the present application. The method comprises at least part of the following contents:

s201, receiving adjustment time information of a filter sent by a network device, wherein the adjustment time information comprises any two of adjustment start time, adjustment end time and adjustment duration.

S202, adjusting the bandwidth of the filter according to the adjustment time information.

In the embodiment of the present application, the network device needs to perform LBT on each RB-set in BWP. And when there is an RB-set in the BWP, which does not successfully perform the LBT, the network device may transmit adjustment time information of the filter corresponding to the UE and instruct the UE to adjust the bandwidth of the filter based on the adjustment time information.

Wherein the network device does not send data to the UE from the start of the adjustment to the end of the adjustment duration.

Alternatively, the filter may be any filter in the communication system, such as a baseband filter.

Wherein a baseband filter is typically used to filter the baseband signal. For example, the baseband transmission filter is used to limit the signal frequency band, so as to avoid interference with other systems; the receiving end filter is used for filtering noise and interference brought by the channel.

In a possible implementation manner, the network device may select any time period during which data is not transmitted to the UE according to the time information of transmitting data to the UE, so as to determine the adjustment time information.

In another possible implementation manner, the network device may also select an arbitrary time period to determine the adjustment time information, and then, in a time period corresponding to the adjustment time information, if there is data to be sent to the UE, may wait for the end of the adjustment time period and then send the data to the UE.

Alternatively, the UE may determine a period of time based on the adjustment time information, and then adjust the bandwidth of the filter during the period of time. For example, when the system bandwidth is 80MHz and the bandwidth of each RB-set of the system bandwidth is 20MHz, there are 4 RB-sets to perform LBT in parallel, and if there is one RB-set that does not successfully perform LBT, the bandwidth of the filter of the UE may be adjusted from 80MHz to 60MHz, or from 80MHz to both 40MHz and 20MHz bandwidths, so as to avoid that the RB-set that does not successfully perform LBT affects the reception of data by the UE.

The method for adjusting the filter provided by the embodiment of the application comprises the following steps: and the UE receives the adjustment time information of the filter sent by the network equipment and adjusts the bandwidth of the filter according to the adjustment time information. In other words, in the embodiment of the present application, the UE adjusts the filter in the time period specified by the network device, and the network device may not perform data transmission in the time period, so that the problem that the UE loses data due to the fact that the UE cannot receive data during the time period of adjusting the filter can be effectively avoided.

Based on what is described in the foregoing embodiment, in a possible implementation manner, the receiving the filter adjustment time information sent by the network device in step S201 includes:

and receiving resource information corresponding to the target time domain resource sent by the network equipment, wherein the resource information comprises any two of starting information, ending information and length information corresponding to the target time domain resource, and determining the adjustment time of the filter based on the resource information. Wherein, the network device does not transmit data on the target time domain resource.

In the embodiment of the application, the network device may indicate the adjustment time information to the UE through a physical downlink control channel (Pysical layer Downlink Control channel, PDCCH). That is, the UE may determine the adjustment time information according to the time domain resources transmitted to the UE by the base station.

Optionally, the start information may be symbol information of a start symbol corresponding to the target time domain resource; the length information is the number of symbols corresponding to the target time domain resource; the ending information is the symbol information of the last symbol corresponding to the target time domain resource.

In a possible embodiment, the UE may receive DCI sent by the network device, where the DCI includes any two of the start information, the end information, and the length information.

For example, the UE receives DCI sent by the network device, where the DCI includes symbol information of a start symbol corresponding to the target time domain resource and the number of symbols corresponding to the target time domain resource; then, the UE may determine the adjustment start time based on the position of the start symbol in the time domain, determine a duration occupied by the target time domain resource in the time domain based on the number of symbols corresponding to the target time domain resource, and determine the duration as the adjustment duration.

For a better understanding of the embodiments of the present application, reference is made to fig. 3a to 3c, and fig. 3a to 3c are schematic diagrams of time domain resources in the method for adjusting a filter according to the embodiments of the present application.

In fig. 3a, there are four RB-sets in one BWP, which can be understood as a set of consecutive resource blocks in one carrier, and thus, 4 RB-sets correspond to four resource block sets: resource block set 1, resource block set 2, resource block set 3, and resource block set 4. After the network device performs LBT on the resource block set 1, the resource block set 2, the resource block set 3, and the resource block set 4, it is assumed that the resource block set 3 does not successfully perform LBT. The network device may indicate to the UE that a position corresponding to a certain symbol on the time domain resource is an adjustment start time and a time occupied by a number of symbols is an adjustment duration through DCI in a processing Group Common physical downlink control channel (GC-PDCCH).

In fig. 3b, the network device may indicate to the UE in the GC-PDCCH that the position corresponding to a certain symbol on the time domain resource is the adjustment end time, and the time occupied by a number of symbols is the adjustment duration through the DCI.

In fig. 3c, the network device may indicate to the UE that a position corresponding to a certain symbol on the time domain resource is an adjustment start time, and a position corresponding to a certain symbol is an adjustment end time in the GC-PDCCH through the DCI.

In another possible implementation manner, the UE may receive a higher layer signaling sent by the network device, where the higher layer signaling includes any two of the start information, the end information, and the length information.

For a better understanding of the embodiments of the present application, referring to fig. 4a to 4c, fig. 4a to 4c are schematic diagrams of time domain resources in the method for adjusting a filter according to the embodiments of the present application.

Alternatively, the network device may activate the existing higher layer parameter "rate Match Pattern Group1/2" or increase the higher layer parameter "rate Match Pattern Group3" using a rate matching indicator (rate match indicator) in the physical downlink control channel (Physical Downlink Control Channel, PDCCH for short). "IE symbols In Resource Block" in "rate Match Pattern" can be used to: the physical downlink shared channel (Physical Downlink Shared Channel, abbreviated PDSCH) of the current slot is indicated to receive the last symbols whose starting symbols are time-domain aligned for the initial time and whose time occupied in the time domain is the aligned duration.

Alternatively, since "rate match indicator" is a domain that exists only in DCI format 1_1. Thus, there may be two situations: 1. the field "rate match indicator" is not added to other DCI formats (formats); 2. the field rate match indicator is added to other DCI formats, so that the activation of the high-layer signaling is completed.

In fig. 4a, there are four RBs-sets within one BWP, namely resource block set 1, resource block set 2, resource block set 3 and resource block set 4. After the network device executes LBT on the resource block set 1, the resource block set 2, the resource block set 3 and the resource block set 4 respectively, assuming that the resource block set 3 does not execute LBT successfully, the network device may indicate to the UE through DCI activation high-layer signaling that a position corresponding to a certain symbol on the time domain resource is an adjustment start time, and time occupied by a plurality of symbols is an adjustment duration.

In fig. 4b, the network device may indicate to the UE that a position corresponding to a certain symbol on the time domain resource is an adjustment end time, and a time occupied by a number of symbols is an adjustment duration through DCI activation higher layer signaling.

In fig. 4c, the network device may indicate to the UE that a position corresponding to a certain symbol on the time domain resource is an adjustment start time, and indicate that a position corresponding to a certain symbol on the time domain resource is an adjustment end time through DCI activation higher layer signaling.

In another possible implementation manner, the UE may receive a higher layer signaling sent by the network device, where the higher layer signaling includes any one of the start information, the end information, and the length information; and receiving DCI sent by the network equipment, wherein the DCI comprises any one of the two rest items which are not in the high-layer signaling in the starting information, the ending information and the length information.

For example, the adjustment duration is configured by radio resource control (Radio Resource Control, abbreviated RRC), and the DCI indicates the adjustment start time of the filter to the UE.

In the embodiment of the application, the network device can instruct the UE to adjust the adjustment time information of the filter through DCI or higher layer signaling, and the UE can effectively avoid the problem that the UE loses data due to the fact that the UE cannot receive data during the period of adjusting the filter by adjusting the filter according to the adjustment time information indicated by the network device.

Based on what is described in the above embodiments, in one possible embodiment of the present application, after adjusting the bandwidth of the filter, the UE receives data transmitted by the network device through each RB-set that successfully performs LBT in BWP and an intra-carrier guard bandwidth (intra carrier guard band) between two adjacent RBs-sets that successfully perform LBT.

For a better understanding of the embodiments of the present application, referring to fig. 5, fig. 5 is a schematic diagram of two types of intra-carrier protection bandwidths in the method for adjusting a filter according to the embodiments of the present application.

As shown in fig. 5, for the Intra-carrier guard bandwidth (Intra-carrier guard band) between two RBs sets, there are two types: the first type is a guard bandwidth between two adjacent RBs-set that successfully perform LBT, and the second type is a guard bandwidth between an RB-set that successfully performs LBT and an RB-set that does not successfully perform LBT. In the embodiment of the present application, for the first class of guard bandwidth, the guard bandwidth may also be used to schedule transmission of PDSCH, so that the utilization rate of resources may be improved.

Based on the descriptions in the above embodiments, the embodiments of the present application further provide a method for adjusting a filter, which is applied to a network device. Referring to fig. 6, fig. 6 is a second flowchart of a method for adjusting a filter according to an embodiment of the present application. The method comprises the following steps:

And S602, when the RB-set which does not successfully execute the LBT exists in the BWP, sending the adjustment time information of the filter corresponding to the UE, wherein the adjustment time information comprises any two of adjustment starting time, adjustment ending time and adjustment duration.

In a possible embodiment, the method further comprises:

In the embodiment of the invention, the UE adjusts the filter in the time period appointed by the network equipment, and the network equipment does not send data to the UE in the time period, so that the problem that the data is lost in the period of adjusting the filter by the UE can be effectively avoided.

In a possible implementation manner, the step S602 of sending, to the UE, the adjustment time information of the filter corresponding to the UE includes:

and sending resource information corresponding to the target time domain resource to the UE, wherein the resource information comprises any two of starting information, ending information and length information corresponding to the target time domain resource. Wherein the network device does not perform data transmission on the target time domain resource.

Optionally, the initial information is symbol information of an initial symbol corresponding to the target time domain resource; the length information is the number of symbols corresponding to the target time domain resource; the ending information is the symbol information of the last symbol corresponding to the target time domain resource.

In a possible implementation manner, the network device may send DCI to the UE, where the DCI includes any two of the start information, the end information, and the length information.

In another possible implementation manner, the network device may also send a higher layer signaling to the UE, where the higher layer signaling includes any one of the start information, the end information, and the length information; and transmitting DCI to the UE, wherein the DCI comprises any one of the two rest items which are not in the high-layer signaling in the starting information, the ending information and the length information.

In another possible implementation manner, the network device may further send a higher layer signaling to the UE, where the higher layer signaling includes any two of the start information, the end information, and the length information.

In another possible implementation, after the UE adjusts the filter, the network device may send data to the UE based on the RB-set that successfully performs LBT in BWP and the intra-carrier guard bandwidth (intra carrier guard band) between two neighboring RBs-sets that successfully perform LBT.
