Description

FFP switching method and device for unlicensed frequency band
Technical Field
The embodiment of the invention relates to the field of communication, in particular to a method and equipment for switching a fixed frame period (Fixed Frame Period, FFP) of an unlicensed frequency band.
Background
A fifth Generation mobile communication technology (5 th-Generation, 5G) is an important application scenario in the 5G field, and unlicensed frequency bands can be used to transmit data. Unlicensed bands are shared by multiple technologies (RATs) and therefore must be used in accordance with rules such as listen before talk (Listen Before Talk, LBT), maximum channel occupancy time MCOT (Maximum Channel Occupancy Time), etc. to ensure that all communication nodes can use the resource fairly.
The frame-based device (Frame Based Equipment, FBE) means that the transmission/reception timing of the communication node adopts a periodic structure with a period of FFP, and the FBE communication node occupies a channel using an LBT-based channel access mechanism.
In the related art, the network device informs the terminal device of FFP configuration information through system information block-1 (System Information Block-Type1, SIB-1) or radio resource control (Radio Resource Control, RRC) signaling. This approach may result in FFPs that may not be updated for a long time, considering the characteristics of SIB-1 and RRC signaling. For some traffic types, such as ultra-high reliability and low latency communications (Ultra Reliable Low Latency Communications, URLLC); or some bursty traffic, long-term adoption of the same FFP configuration may result in service requirements that are not met or are inefficient.

In the embodiment of the invention, the network equipment is a device which is deployed in the wireless access network and used for providing a wireless communication function for the terminal equipment. The network device may be a base station, which may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of devices with base station functionality may vary. For example, in LTE networks, referred to as Evolved nodebs (enbs or enodebs), in third generation (3rd Generation,3G) networks, referred to as nodebs (Node bs), in 5G systems, as next generation nodebs (gnbs), or network devices in subsequent Evolved communication systems, etc., although the term is not limiting.
As shown in fig. 1, an embodiment of the present invention provides a fixed frame period (Fixed Frame Period, FFP) handover method 100 of an unlicensed band, which may be performed by a terminal device, in other words, by software or hardware installed in the terminal device, the method comprising the steps of:
s102: and switching the FFP according to the configuration information of the target FFP.
In various embodiments of the present disclosure, the configuration information of the target FFP may only include length information of the target FFP (i.e., the FFP after handover), and in this example, a start position of the target FFP may be pre-agreed, for example, the start position of the target FFP is aligned with an end position of the current FFP. Optionally, the configuration information of the target FFP may also only include a starting position of the target FFP, in this example, a length of the target FFP may be pre-agreed, for example, the network device may pre-configure a plurality of FFP lengths, and the length of the target FFP may be one of the plurality of FFP lengths that is smaller than a first one of the current FFP lengths, a minimum FFP length, and so on. Optionally, the configuration information of the target FFP may further include a start position of the target FFP and a length of the target FFP.
The start position of the target FFP mentioned above may be an absolute position, which may be determined according to a system frame or a system time, etc., for example, the start position of the target FFP is aligned with the start position of a specified system frame; the starting position of the target FFP may also include an offset relative to the reference position. The reference position may be a start position, an end position, or a common reference position of the current FFP.
S104: channel interception and transmission are performed according to the target FFP.
Alternatively, in one embodiment, the network device may configure a plurality of FFP configuration information for the terminal device in advance, and the configuration information of the target FFP is one of the plurality of FFP configuration information. In this way, in S102, the terminal device may directly initiate the operation of FFP handover, that is, handover FFP according to the configuration information of the target FFP, where the configuration information of the target FFP may be different from the FFP configuration information corresponding to the FFP currently being used.
Optionally, the configuration information of the target FFP is obtained by the terminal device according to at least one of: priority of transmission information, transmission frequency, data volume.
In this embodiment, the terminal device may also send configuration information of the target FFP to the network device. Specifically, before switching the FFP, the terminal device may send an index corresponding to configuration information of the target FFP (or referred to as an index corresponding to the target FFP) to the network device, so as to save signaling overhead; alternatively, the terminal device may send specific configuration parameters of the target FFP to the network device before switching the FFP. The target FFP referred to in various embodiments of the present specification may be a FFP after handover.
In this embodiment, the network device may also perform an operation of switching the FFP after receiving the configuration information of the target FFP, where the FFP after the terminal device is switched (i.e., the target FFP) is aligned with the start position of the FFP after the network device is switched, and the FFP is equal in length.
Optionally, in this embodiment, the network device may further send an acknowledgement message (ACK) to the terminal device after receiving the configuration information of the target FFP, and the terminal device may switch the FFP according to the configuration information of the target FFP after receiving the acknowledgement information.
Optionally, in another embodiment, before S102, the terminal device may send a handover request message to the network device, where the handover request message is used to request to handover the FFP, so that the network device may send configuration information of the target FFP to the terminal device after receiving the handover request message, and the terminal device may handover the FFP according to the configuration information of the target FFP. The network device may also perform the operation of switching the FFP synchronously, where the FFP after the terminal device is switched (i.e., the target FFP) and the starting position of the FFP after the network device is switched are aligned, and the lengths of the FFPs are equal.
In this example, the handover request message sent by the terminal device to the network device may further include at least one of the following: the priority, transmission frequency, data volume, etc. of the transmission information, so that the network device can determine the configuration information of the target FFP according to the priority, transmission frequency, data volume, etc. of the transmission information, and send the configuration information to the terminal device.
In the embodiment of the invention, the terminal equipment can actively initiate FFP switching operation according to the priority, frequency, data volume and the like of the transmission information, so that the problem of long updating period of FFP configuration in the related technology is solved, the service requirement is conveniently met, and the resource utilization rate is improved.
As mentioned in the foregoing embodiments, the configuration information of the target FFP is obtained according to at least one of the following: priority of transmission information, transmission frequency, data volume. Alternatively, the different priorities of transmitting information may correspond to different types of traffic. For example, the more important the type of service, the shorter the period of FFP after switching according to the configuration information of the target FFP, whereas the less important the type of service, the longer the period of FFP after switching; the higher the transmission frequency is, the shorter the period of the FFP after switching is, otherwise, the lower the transmission frequency is, the longer the period of the FFP after switching is; the larger the data amount, the longer the period of the FFP after switching, whereas the smaller the data amount, the shorter the period of the FFP after switching.
The types of traffic mentioned above include for example URLLC, enhanced mobile broadband (enhanced Mobile Broadband, eMBB) etc., wherein the traffic type URLLC is higher in demand than the traffic type eMBB for latency, reliability etc., or is called traffic type URLLC with higher priority than the traffic type eMBB.
In order to describe the FFP switching method of the unlicensed band provided in the embodiment of the present invention in detail, the following description will be made with reference to several specific embodiments.
Example 1
As shown in fig. 2, in this embodiment, the terminal device may switch the FFP according to configuration information of the target FFP; the terminal device may also notify the network device of configuration information of the target FFP through uplink control information (Uplink Control Information, UCI) before switching the FFP. Wherein, the UCI may be configured scheduling (UCI), namely CG-UCI; other types of UCI are also possible.
Fig. 2 shows three FFPs altogether schematically, wherein the first FFP is the currently used FFP, and the second and third etc. subsequent FFPs are the FFPs after handover, i.e. the target FFP. Before starting transmission at the starting time of the FFPs, the terminal equipment needs to perform channel idle estimation (Clear Channel Assess, CCA), and if the terminal equipment judges that the terminal equipment is idle, the terminal equipment can immediately send the terminal equipment; otherwise, no transmission is allowed for the immediately following FFP duration, where three FFPs in fig. 2 each determine that the channel is clear when CCA is performed.
Within the FFP, the total duration of the continuous transmission by the terminal device without re-estimating the availability of the channel is defined as the channel occupancy time (Channel Occupancy Time, COT), immediately after the COT, an Idle Period (Idle Period) which is continued until the start of the next FFP.
In the embodiment shown in fig. 2, after a processing or switching time, the terminal device starts channel interception and transmission according to the configuration of the target FFP at the next active time, that is, channel interception and transmission is performed at the second and third FFPs shown in fig. 2, and the transmitted data is shown as a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) and/or a physical uplink control channel (Physical Uplink Control Channel, PUCCH) in fig. 2.
In this embodiment, the configuration information of the target FFP may be one configuration index, where each index corresponds to one FFP configuration (or FFP). Wherein the correspondence of the index and the FFP configuration (or FFP) may be preconfigured by the RRC.
Before the embodiment is performed, the network device may send a plurality of FFP configuration information to the terminal device, where each FFP configuration information corresponds to a unique index, and the configuration information of the target FFP is one of the plurality of FFP configuration information. When the terminal device prepares to switch FFP configuration, an index corresponding to the new configuration (i.e., configuration information of the target FFP) may be transmitted to the network device through UCI.
It should be noted that, the above description refers to that each FFP configuration information corresponds to a unique index, and may also be referred to as that (after configuration) each FFP corresponds to a unique index.
After the current FFP is finished, the network device and the terminal device can perform channel interception and transmission according to the configuration information of the target FFP from the next FFP. In this case, the configuration information of the FFP (including the configuration information of the target FFP, etc.) may not include the start position information (i.e., start time) of the FFP, and only include the length information of the FFP.
In other embodiments, the starting position of the first FFP after the handover may not be aligned with the ending position of the current FFP, that is, the starting position of the second FFP and the ending position of the first FFP in fig. 2 may not be aligned (or referred to as non-overlapping, etc.), specifically:
if the residual time of the current FFP is insufficient for operations such as FFP switching processing, channel interception and transmission are started at the next effective FFP starting position according to target FFP configuration; or alternatively, the process may be performed,
if the remaining time of the current FFP is actually much longer than the FFP switching processing time, the current FFP may be ended in advance, starting according to the start position of the configuration of the FFP after switching.
In this embodiment, the configuration information of the FFP includes start position information and length information of the FFP after the switching. The starting position may be an absolute position information, where the absolute position information may refer to a specific time domain position; or an offset relative to a reference position. The reference location may be a starting location, an ending location of the current FFP, or a common reference location. The offset may represent a value; it may also represent a plurality of values, each value being an integer multiple of this offset. Specifically, for example, the offset is indicated as 2slots (slots), and the offset may represent only the position offset of 2slots, or may represent the position offset as 4slots,6slots,8slots, or the like, and the specific value of the offset may be determined according to the processing duration required for FFP handover, or the like.
The above-mentioned common reference location may be a location related to the terminal device transmitting the configuration information of the target FFP, for example, the common reference location may be a location where UCI transmission is completed or a location where UCI transmission starts, and on the network device side, the common reference location is a location where UCI is received. Second, for the case of a response (see the second embodiment, later, fig. 3, the common reference location may also be the location where the network device has sent the response (i.e. the location where the terminal device has received the response), and the response may be ACK or configuration information of the target FFP.
In this embodiment, the terminal device and the network device may know in advance the processing time length required for the FFP handover. This embodiment may indicate a larger value (e.g., 4slots,6slots,8slots, etc.) by a smaller bit (e.g., 2 slots) to facilitate saving signaling overhead.
Alternatively, in other embodiments, the terminal device may also directly indicate the configuration information of the target FFP to the network device in the UCI, instead of the index corresponding to the configuration information of the target FFP (or the target FFP).
In this embodiment, the network device only needs to configure the terminal device with an initial set of FFP configurations. As above, if the start position of the FFP after handover (i.e., the target FFP) defaults to be aligned with the end position of the current FFP, the terminal device only needs to indicate the length of the target FFP to the network device.
In addition, the terminal device may also indicate the starting position and length of the target FFP in UCI. As described above, the start position may be an absolute position or an offset with respect to the reference position. The reference location may be a starting location, an ending location of the current FFP, or a common reference location. The offset may represent a single value or a plurality of values, each value being an integer multiple of the offset. Specifically, for example, the offset is indicated as 2slots (slots), and the offset may represent only the position offset of 2slots, or may represent the position offset as 4slots,6slots,8slots, or the like, and the specific value of the offset may be determined according to the processing duration required for FFP handover, or the like.
Example two
As shown in fig. 3, in this embodiment, the terminal device may request to the network device to switch the FFP, and perform a switching operation of the FFP after being allowed by the network device.
Fig. 3 shows three FFPs in a co-schematic manner, wherein the first FFP is the FFP that the network device obtains and shares to the terminal device, and the second and third etc. subsequent FFPs are the FFPs that the terminal device obtains and uses.
In this embodiment, the interval time between PUSCH/PUCCH and PDCCH transmitted by the terminal device is longer than 16 microseconds (us), so the terminal device also performs CCA operation within the COT obtained by the network device, and transmits PUSCH/PUCCH if the channel is determined to be empty.
In this embodiment, the terminal device may send an FFP handover Request to the network device through UCI (i.e., change Request in fig. 3); alternatively, the terminal device may transmit configuration information of the target FFP to the network device through UCI (i.e., change Request in fig. 3). .
1) In the case that the terminal device transmits the configuration information of the target FFP, the configuration information of the target FFP may be an index corresponding to the configuration information of the target FFP; a specific FFP configuration is also possible, which includes at least any one of the start position of the target FFP and the length of the target FFP. The relevant content of the configuration information about the target FFP can be found in embodiment one, and the description is not repeated here to avoid repetition.
The network device may give an Acknowledgement (ACK) feedback to the terminal device after receiving the configuration information of the target FFP transmitted by the terminal device (see response in fig. 3). After receiving the ACK feedback, the terminal device may perform the FFP handover operation.
2) In the case where the terminal device transmits the FFP handover request, the network device may transmit configuration information of the target FFP (see response in fig. 3) to the terminal device. Similarly, the relevant content of the configuration information of the target FFP may be referred to as embodiment one, and the description will not be repeated here to avoid repetition.
After receiving the configuration information of the target FFP, the terminal device may perform the FFP handover operation.
In this example, the FFP handover request message sent by the terminal device to the network device may further include at least one of the following: the priority, transmission frequency, data volume, etc. of the transmission information, so that the network device can determine the configuration information of the target FFP according to the priority, transmission frequency, data volume, etc. of the transmission information, and send the configuration information to the terminal device.
