In addition, it is to be understood that the terms first, second, etc. in the description of the present application are used for distinguishing between the descriptions and not necessarily for describing a sequential or chronological order.
In a wireless communication system, a base station and a UE may perform wireless communication using air interface resources. For example, in a 5G system, the air interface resources include frequency domain resources, which may be located in a set frequency range. The frequency range may also be referred to as a frequency band (band) or frequency band. In the frequency domain, a center point of the frequency domain resource may be referred to as a center frequency point, and a width of the frequency domain resource may be referred to as a Bandwidth (BW). Exemplarily, fig. 1 illustrates a location diagram of a frequency domain resource. As shown in fig. 1, the frequency domain resource may be part or all of the resources in a frequency band, the bandwidth of the frequency domain resource is W, and the frequency of the center frequency point is F. The frequency of the boundary point of the frequency domain resource is F-W/2 and F + W/2 respectively, and can also be described as that the frequency of the highest frequency point in the frequency domain resource is F + W/2, and the frequency of the lowest frequency point in the frequency domain resource is F-W/2. In a wireless communication system, frequency domain resources used for downlink communication and frequency domain resources used for uplink communication may be the same or different, and the present application is not limited thereto.
When the base station and the UE perform wireless communication by using the frequency domain resources, the base station manages the system frequency domain resources, and allocates the frequency domain resources for the UE from the system frequency domain resources, so that the base station and the UE can perform communication by using the allocated frequency domain resources. The system frequency domain resource may be a frequency domain resource that can be managed and allocated by the base station, and may also be a frequency domain resource that can be used for communication between the base station and the UE. In the embodiments of the present application, the system frequency domain resources may also be referred to as system resources or transmission resources. In the frequency domain, the width of the system frequency domain resource may be referred to as a bandwidth of the system frequency domain resource, and may also be referred to as a system bandwidth or a transmission bandwidth. The base station may configure a plurality of bandwidth part BWPs in a carrier and may configure parameters (numerology) independently for each BWP of the plurality of BWPs. A base station may configure one or more BWPs for one UE, where the numerology of BWPs includes subcarrier spacing. That is, for any UE, multiple BWPs may be configured on one carrier, and the numerology configured for each BWP may be the same or different, and in this embodiment of the present application, the BWP may also be referred to as a bandwidth resource, a frequency resource portion, a partial frequency resource, a carrier BWP, or other names, which is not limited in this application.
In each figure of the embodiment of the invention, D represents DL, U represents UL, and Un represents Unknown resource Unknown.
The base station may configure one subcarrier spacing for the UE as a reference subcarrier spacing (Ref-SCS), and determine a slot format (slot format) of a target BWP for other subcarrier spacings of the UE according to the reference subcarrier spacing and the slot format (slot format) of the reference subcarrier spacing. For example, as shown in fig. 2, taking cell-specific semi-static DL/UL allocation as an example, that is, taking cell-level configuration slot format as an example, for BWP with subcarrier spacing of 30kHz or 60kHz, if Ref-SCS is 15kHz, the slot format of BWP with subcarrier spacing of 30kHz or 60kHz can be determined according to the slot formats of Ref-SCS and Ref-SCS. Specifically, the time slot format of the subcarrier spacing is determined according to the ratio of the subcarrier spacing to the Ref-SCS. Taking Ref-SCS as 15kHz, subcarrier spacing as 30kHz, and ratio as 2 as an example, an uplink time domain resource of Ref-SCS corresponds to 2 uplink time domain resources whose subcarrier spacing is 30kHz, a downlink time domain resource of Ref-SCS corresponds to 2 downlink time domain resources whose subcarrier spacing is 30kHz, and an unknown resource of Ref-SCS corresponds to 2 unknown resources whose subcarrier spacing is 30kHz, specifically see fig. 2, where each cell in fig. 2 represents a time slot. The unknown resource determined in the cell-level semi-static time domain resource allocation may be further configured with a time slot format, which is referred to as UE-level semi-static time domain resource allocation (UE-specific semi-static DL/UL assignment), that is, a format of each time slot configured at the UE level, and is similar to the cell-level configuration time slot format in fig. 2, except that the cell-level configuration time slot format is in units of time slots, and the UE-level configuration time slot format is in units of symbols, as shown in fig. 3.
However, when UE-specific semi-static DL/UL assignment is taken as an example, when the configuration of the target BWP is determined according to the configuration of Ref-SCS, if Ref-SCS is larger than the subcarrier spacing of the target BWP, then the slot format determined according to the time domain boundary alignment in one slot of the target BWP may not meet the specified DL-Unknown-UL pattern (pattern), and more than 1 uplink/downlink transition point may occur in one slot, which may result in an increase in uplink/downlink transition overhead of the UE. For example, as shown in fig. 4: when Ref-SCS is equal to 30kHz, the subcarrier interval configured by the target BWP is 15kHz, the structure of one timeslot on the target BWP needs to be determined according to the structure of the timeslot with the two subcarrier intervals of 30kHz, and the timeslot structure determined on the target BWP is as shown in fig. 4, and does not conform to the DL-Unknown-UL mode, that is, does not conform to the structure in which there is at most one uplink/downlink transition point in the timeslot structure, and cannot satisfy the DL-Unknown-UL pattern timeslot format.
In the embodiment of the present application, a base station or a UE determines, according to a reference subcarrier interval and a slot format of a slot corresponding to the reference subcarrier interval, a slot length of a target BWP with a subcarrier interval of a target BWP smaller than the reference subcarrier interval and a slot format of a slot of the target BWP, so as to solve the problem that in the prior art, when the subcarrier interval of the target BWP is smaller than the reference subcarrier interval, the slot format of the slot of the target BWP meeting the DL-Unknown-UL pattern slot format cannot be configured, thereby saving resource overhead, improving resource utilization rate, and improving system transmission rate.
The following describes a scheme for determining a slot format provided in the present application in detail with reference to the accompanying drawings.
In the embodiment of the present application, the apparatus for executing the UE side method may be a UE, or may be an apparatus capable of supporting the UE to implement the method. The apparatus capable of supporting the UE to implement the method may be a circuit, a chip system, or a module, which is not limited in this application. In the method provided in the embodiment of the present application, a device for performing the UE-side method is described as an example of a UE.
Similarly, in the embodiment of the present application, the apparatus for performing the method on the base station side may be a base station, or may be an apparatus capable of supporting the base station to implement the method. The apparatus capable of supporting the base station to implement the method may be a circuit, a chip system, or a module, and the application is not limited thereto. In the method provided in the embodiment of the present application, a device that executes the base station side method is described as an example of a base station.
Referring to fig. 5, a flowchart of a method for slot format determination provided in the present application may be performed by a UE or a base station. The method comprises the following steps:
step S501, in the time slot of the target bandwidth part BWP, the 1 st time slot corresponding to the reference subcarrier intervalWherein, a length of a slot corresponding to a subcarrier interval of the target BWP is equal to a sum of lengths of slots corresponding to K reference subcarrier intervals, a ratio of the reference subcarrier interval to the subcarrier interval of the target BWP is K, and K is 2nAnd n is a positive integer greater than or equal to 1.
Specifically, the reference subcarrier interval may be 60kHz and 30kHz, the subcarrier interval of the target BWP may be 30kHz and 15kHz, and when the reference subcarrier interval is 60kHz and the subcarrier interval of the target BWP is 30kHz, K is equal to 2, that is, the sum of the slot lengths corresponding to the 2 reference subcarrier intervals is equal to one slot length corresponding to the subcarrier interval of the target BWP; when the value of the reference subcarrier interval is 60kHz and the subcarrier interval of the target BWP is 15kHz, K is equal to 4, that is, the sum of the slot lengths corresponding to the 4 reference subcarrier intervals is equal to one slot length corresponding to the subcarrier interval of the target BWP.
Step S502, in the time slot of the target BWP, determining the uplink time domain resource of the time slot of the target BWP according to the uplink time domain resource of the kth time slot corresponding to the reference subcarrier interval.
Step S503, in the time slot of the target BWP, the resources other than the downlink time domain resource of the time slot of the target BWP and the uplink time domain resource of the time slot of the target BWP include unknown resources.
Optionally, in the time slot of the target BWP, other time domain resources except the downlink time domain resource of the time slot of the target BWP and the uplink time domain resource of the time slot of the target BWP are unknown resources.

The following description will be given by taking four specific combinations as examples.
In a first mode, in a time slot of the target BWP, determining a downlink time domain resource of the time slot of the target BWP according to a downlink time domain resource of a 1 st time slot corresponding to the reference subcarrier interval and L symbols adjacent to the downlink time domain resource of the 1 st time slot, where L is a positive integer greater than or equal to 1 and less than K; and in the time slot of the target BWP, determining the uplink time domain resource of the time slot of the target BWP according to the uplink time domain resource of the Kth time slot corresponding to the reference subcarrier interval and M symbols adjacent to the uplink time domain resource of the Kth time slot, wherein M is a positive integer. For example, M is a positive integer greater than or equal to 1 and less than K; for another example, M may be a positive integer greater than K.
For example, assuming that the value of the reference subcarrier spacing is 30kHz, the subcarrier spacing of the target BWP is 15kHz, and the number of symbols of each timeslot is 14, according to which K may be equal to 2, that is, the sum of the slot lengths corresponding to the 2 reference subcarrier spacings is equal to the slot length corresponding to the subcarrier spacing of the target BWP, the slot structure of the slot corresponding to each reference subcarrier spacing is as shown in fig. 7, where the first 5 symbols of the first timeslot are DL, the middle 4 symbols are unswn, the last 5 symbols are UL, the first 4 symbols of the 2 nd timeslot are DL, the middle 5 symbols are unswn, and the last 5 symbols are UL, the downlink time domain resource of the target BWP timeslot is determined according to the downlink time domain resource of the 1 st timeslot corresponding to the reference subcarrier spacing and a symbol (unswn) adjacent to the downlink resource, and the target time domain resource of the 2 nd timeslot is determined according to the reference subcarrier spacing and the uplink symbol (unswn) adjacent to the uplink time domain resource An uplink time domain resource of the slot.
Specifically, the first mapping manner Alt1 shown in fig. 7 can be expressed by a formula: DL + Un- > DL, Un + UL- > UL, i.e.: if there are downlink symbols and unknown symbols in the configuration of the slot corresponding to the reference subcarrier interval corresponding to one symbol duration in the slot of the target BWP, the symbols on the target BWP are determined to be downlink symbols; if there is an uplink symbol and an unknown symbol in the reference configuration corresponding to one symbol duration in the slot of the target BWP, the symbol on the target BWP is determined to be the uplink symbol.

For example, assuming that the value of the reference subcarrier spacing is 30kHz, the subcarrier spacing of the target BWP is 15kHz, and the number of symbols of each timeslot is 14, accordingly K may be equal to 2, that is, the sum of the timeslot lengths corresponding to 2 reference subcarrier spacings is equal to a timeslot length corresponding to the subcarrier spacing of the target BWP, and the timeslot structure of the timeslot corresponding to each reference subcarrier spacing is as shown in fig. 7, where the first 5 symbols of the first timeslot are DL, the middle 4 symbols are unswn, the last 5 symbols are UL, the first 4 symbols of the 2 nd timeslot are DL, the middle 5 symbols are unswn, and the last 5 symbols are UL, the downlink time domain resource of the timeslot of the target BWP is determined according to the downlink time domain resource of the 1 st timeslot corresponding to the reference subcarrier spacing except the last symbol, and the uplink time domain resource of the 2 nd timeslot corresponding to the reference subcarrier spacing and an adjacent uplink time domain resource (unswn) are determined.
Specifically, the second mapping manner Alt2 shown in fig. 7 can be expressed by a formula: DL + Un- > Un, Un + UL- > UL, i.e.: a downlink symbol and an unknown symbol are in the configuration of a time slot corresponding to a reference subcarrier interval corresponding to one symbol duration in the time slot of a target BWP, and the symbol on the target BWP is determined as the unknown symbol; if there is an uplink symbol and an unknown symbol in the reference configuration corresponding to one symbol duration in the slot of the target BWP, the symbol on the target BWP is determined to be the uplink symbol.

For example, assuming that the reference subcarrier spacing is 30kHz, the subcarrier spacing for the target BWP is 15kHz, and the number of symbols per slot is 14, it is possible that K is equal to 2, that is, the sum of the slot lengths corresponding to the 2 reference subcarrier intervals is equal to one slot length corresponding to the subcarrier interval of the target BWP, the slot structure of the slot corresponding to each reference subcarrier interval is shown in fig. 7, the first 5 symbols of the first slot are DL, the middle 4 symbols are nknown, the last 5 symbols are UL, the first 4 symbols of the 2 nd slot are DL, the middle 5 symbols are nknown, the last 5 symbols are UL, determining the downlink time domain resource of the target BWP time slot according to the downlink time domain resource of the 1 st time slot corresponding to the reference subcarrier interval and a symbol (Unknown) adjacent to the downlink time domain resource, and removing a symbol according to the uplink time domain resource of the 2 nd time slot corresponding to the reference subcarrier interval to determine the uplink time domain resource of the time slot of the target BWP.
Specifically, the mapping method can be expressed as a third mapping method Alt3 shown in fig. 7, and is expressed by a formula: DL + Un- > DL, Un + UL- > Un, i.e.: if there are downlink symbols and unknown symbols in the configuration of the slot corresponding to the reference subcarrier interval corresponding to one symbol duration in the slot of the target BWP, the symbols on the target BWP are determined to be downlink symbols; if there is an uplink symbol and an unknown symbol in the reference configuration corresponding to one symbol duration in the slot of the target BWP, the symbol on the target BWP is determined to be the unknown symbol.

For example, assuming that the reference subcarrier spacing is 30kHz, the subcarrier spacing for the target BWP is 15kHz, and the number of symbols per slot is 14, it is possible that K is equal to 2, that is, the sum of the slot lengths corresponding to the 2 reference subcarrier intervals is equal to one slot length corresponding to the subcarrier interval of the target BWP, the slot structure of the slot corresponding to each reference subcarrier interval is shown in fig. 7, the first 5 symbols of the first slot are DL, the middle 4 symbols are nknown, the last 5 symbols are UL, the first 4 symbols of the 2 nd slot are DL, the middle 5 symbols are nknown, the last 5 symbols are UL, determining the downlink time domain resource of the target BWP time slot according to the downlink time domain resource of the 1 st time slot corresponding to the reference subcarrier interval except the last symbol, and removing the first symbol from the uplink time domain resource of the 2 nd time slot corresponding to the reference subcarrier interval to determine the uplink time domain resource of the time slot of the target BWP.
Specifically, the mapping method can be expressed as a fourth mapping manner Alt4 shown in fig. 7, and is expressed by a formula: DL + Un- > Un, Un + UL- > Un, i.e.: if there are downlink symbols and unknown symbols in the configuration of the slot corresponding to the reference subcarrier interval corresponding to one symbol duration in the slot of the target BWP, the symbols on the target BWP are determined to be unknown symbols; if there is an uplink symbol and an unknown symbol in the reference configuration corresponding to one symbol duration in the slot of the target BWP, the symbol on the target BWP is determined to be the unknown symbol.
In this embodiment, when the UE or the base station determines the slot format of the slot of the target bandwidth portion BWP, there is a special case, which is as the following specific embodiment four.
The fourth concrete example,
In a time slot of a target BWP, if a time slot format of the time slot of the target BWP determined according to a reference subcarrier interval and a time slot format of the reference subcarrier interval does not satisfy a downlink DL-Unknown resource Unknown-uplink UL, determining all resources in the time slot of the target BWP to be Unknown resources in the time slot of the target BWP, wherein one time slot length corresponding to the subcarrier interval of the target BWP is equal to the sum of time slot lengths corresponding to K reference subcarrier intervals, a ratio of the reference subcarrier interval to the subcarrier interval of the target BWP is K, and K is 2nAnd n is a positive integer greater than or equal to 1.
When the time slot format of the reference subcarrier interval is determined according to the reference subcarrier interval and the reference subcarrier interval, determining the downlink time domain resource of the time slot of the target BWP according to the downlink time domain resource corresponding to the reference subcarrier interval or the downlink time domain resource and the unknown resource, determining the uplink time domain resource of the time slot of the target BWP according to the uplink time domain resource corresponding to the reference subcarrier interval or the uplink time domain resource and the unknown resource, determining the unknown resource of the time slot of the target BWP according to the unknown resource corresponding to the reference subcarrier interval, and describing that the resource except the downlink time domain resource and the uplink time domain resource in the target BWP is the unknown resource.
For example, the following steps are carried out: assuming that the reference subcarrier spacing is 30kHz, the subcarrier spacing for the target BWP is 15kHz, and the number of symbols per slot is 14, it is possible that K is equal to 2, that is, the sum of the slot lengths corresponding to the 2 reference subcarrier intervals is equal to one slot length corresponding to the subcarrier interval of the target BWP, the slot structure of the slot corresponding to each reference subcarrier interval is shown in fig. 8, the first 6 symbols of the first slot are DL, the middle 2 symbols are nknown, the last 6 symbols are UL, the first 4 symbols of the 2 nd slot are DL, the middle 4 symbols are nknown, the last 6 symbols are UL, according to the K value, the slot format corresponding to the subcarrier spacing of the invalid (invalid) target BWP is determined as shown in fig. 8, but does not satisfy the DL-Unknown-UL pattern slot format, and an effective slot format is defined, that is, all symbols of the slot of the target BWP are determined as Unknown symbols.
In this embodiment, it is also a case that, assuming that the value of the reference subcarrier interval is 30kHz, the subcarrier interval of the target BWP is 15kHz, and the number of symbols of each time slot is 14, according to which K may be equal to 2, that is, the sum of the time slot lengths corresponding to the 2 reference subcarrier intervals is equal to one time slot length corresponding to the subcarrier interval of the target BWP, and the time slot structure of the time slot corresponding to each reference subcarrier interval is as shown in fig. 9, the first 6 symbols of the first time slot are DL, the last 8 symbols are uknown, there is no UL, the first 8 symbols of the 2 nd time slot are uknown, the last 6 symbols are UL, and there is no DL, and according to the K value, the time slot structure of the subcarrier interval of the effective target BWP is determined to be DL in the first 3 symbols, in the middle 8 symbols are uknown, and the last 3 symbols are DL, which is an effective time slot format.
In the embodiment of the present application, the configuration of the number of symbols in each time slot is not limited, and preferably, the number of symbols may be 7.
The above embodiment is described by taking the resource type of the configuration symbol in the timeslot as an example, and it may also be applied to determine the resource type of the second time unit in other first time units, where the first time unit includes a positive integer number of second time units, and the resource type of the second time unit may be DL, UL, or Unknown. For example, the above embodiments are not only applicable to semi-static time domain resource allocation at the UE level, but also applicable to semi-static time domain resource allocation at the cell level, where the difference is that the cell level configuration is a resource format in which a slot is configured in one period, and the UE level configuration is a resource type in which each symbol is configured in each slot. The unit of the one period may be a time unit such as a subframe, a frame, and a millisecond.
