Detailed Description
Embodiments of the present disclosure will be described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements for the same or similar functions throughout. The embodiments described below with reference to the drawings are only exemplary, meaning that they are intended to illustrate and not limit the present disclosure.
Referring to fig. 1, fig. 1 is a flowchart of a method for time cell configuration according to an embodiment of the present disclosure. In this embodiment, the method is performed at the base station side. The base station may be connected to a core network and wirelessly communicate with User Equipment (UE) to provide communication coverage for a corresponding area. The base station may be a macro base station, a micro base station, a pico base station (pico base station), or a femto cell (femtocell). In some embodiments, a base station may be referred to as a radio base station, an access point, a node B, an evolved node B (eNodeB, eNB), ng-eNB, gNB, en-gNB, or other suitable terminology. As shown in fig. 1, the method may include the following blocks.
At block S11, configuration signaling is transmitted to the UE. The configuration signaling may be used to configure the format/state of the time units in the first subset of the set of time units as Uplink (UL), downlink (DL), reserved, or unknown. The unknown format may also be referred to as a flexible format.
The set of time cells may include a plurality of time cells, and the first subset may include some or all of the time cells in the set of time cells. Each time unit may include at least one symbol or slot. The slot duration may be 14 symbols with a regular Cyclic Prefix (CP) and 12 symbols with an extended CP, and a time scale (scale in time) that varies according to the subcarrier spacing used such that there are always an integer number of slots in a 1ms subframe.
The time units configured as UL by the configuration signaling may be referred to as UL time units; the time units configured as DL by the configuration signaling may be referred to as DL time units; the time units configured to be reserved by the configuration signaling may be referred to as reserved time units; the time units configured as unknown by the configuration signaling may be referred to as unknown time units. If the first subset includes a portion of the time units in the set of time units, time units that are not configured by the configuration signaling may be referred to as unconfigured time units. In some embodiments, the default format of the time units is unknown, so time units that are not configured by the configuration signaling may be referred to as unconfigured time units or unknown time units.
In particular, UL time units may be used for UL transmissions (i.e., transmissions from UE to base station), and DL time units may be used for DL transmissions (i.e., transmissions from base station to UE). The retention time units are reserved for subsequent use, or the retention time units are reserved for legacy transmissions (legacy transmission), such as CRS (cell-specific reference signaling) of the LTE system.
Configuration signaling may be used to semi-permanently configure time resource formats in TDD (time division duplex) systems. The configuration signaling may include at least one Radio Resource Control (RRC) signaling. Each RRC signaling may be cell specific or UE specific. When the configuration signaling includes more than one RRC signaling, the time units/formats configured by the different RRC signaling may be completely different, partially identical, or identical. For example, the configuration signaling may include two RRC signaling, one RRC signaling may be used to configure the reserved format and the other RRC signaling may be used to configure the UL, DL, and unknown formats. In particular, the RRC signaling may be prioritized, and the time cell format configured by the lower priority RRC signaling may be covered by the higher priority RRC signaling (override).
At block S12, a Slot Format Indicator (SFI) is transmitted to the UE.
The SFI may be used to dynamically configure the format of the time units in the second subset of the set of time units as uplink, downlink or unknown at the top of the configuration signaling. The second subset does not include time cells in the third subset of the set of time cells. The third subset may be a subset of the first subset and include at least one of uplink, downlink and retention time units configured by configuration signaling. The time units in the third subset cannot be covered by the SFI. For example, the third subset may be comprised of all uplink, downlink and reserved time units in the first subset, and the second subset may be comprised of at least a portion of the unknown time units, at least a portion of the unconfigured time units, or at least a portion of the unknown time units and at least a portion of the unconfigured time units. Unknown and/or unconfigured time units may be covered by the SFI as UL or DL.
The SFI may be carried in Downlink Control Information (DCI) transmitted on a Physical Downlink Control Channel (PDCCH), e.g., DCI format 2_0, with a CRC scrambled by an SFI-Radio Network Temporary Identity (RNTI). The information required for SFI transmission can be configured by a high-level usage parameter SlotFormatIndicator.
The second subset does not include time units in the third subset, so that the SFI will not configure time units in the third subset and collisions between configuration signaling and SFI can be reduced.
Referring to fig. 2, fig. 2 is a flow chart of a method for time cell configuration according to another embodiment of the present disclosure. In this embodiment, the method is performed at the UE side. The UE may be stationary in one example and mobile in another example, such as a cellular telephone, a Personal Digital Assistant (PDA), a wireless modem, a tablet, a laptop, a cordless phone, and the like. As shown in fig. 5, the method may include the following blocks.
At block S21, configuration signaling is received from a base station. The configuration signaling may be used to configure the format of the time units in the first subset of the set of time units as uplink, downlink, reserved, or unknown. The unknown format may also be referred to as a flexible format.
In this embodiment, the configuration signaling may be the configuration signaling as described in the previous embodiment, and will not be described herein.
At block S22, the format of the time units in the first subset is configured according to the configuration signaling.
The time units configured as UL by the configuration signaling may be referred to as UL time units; the time units configured as DL by the configuration signaling may be referred to as DL time units; the time units configured to be reserved by the configuration signaling may be referred to as reserved time units; the time units configured as unknown by the configuration signaling may be referred to as unknown time units. If the first subset includes a portion of the time units in the set of time units, time units that are not configured by the configuration signaling may be referred to as unconfigured time units. In some embodiments, the default format of the time units is unknown, so time units that are not configured by the configuration signaling may be referred to as unconfigured time units or unknown time units.
At block S23, an SFI is received from the base station. The SFI may be used to dynamically configure the format of the time units in the second subset of the set of time units as uplink, downlink or unknown at the top of the configuration signaling.
The SFI may be carried in Downlink Control Information (DCI) transmitted on a Physical Downlink Control Channel (PDCCH), e.g., DCI format 2_0, with a CRC scrambled by an SFI-Radio Network Temporary Identity (RNTI). The information required for SFI transmission can be configured by a high-level usage parameter SlotFormatIndicator. The UE may monitor the SFI in DL time units and some unknown time units (when configured by higher layer parameters).
At block S24, the formats of the other time units in the second subset than the time units in the third subset of the set of time units are configured according to the SFI, and the formats of the time units in the third subset are kept unchanged.
The third subset is a subset of the first subset and includes at least one of uplink, downlink, and retention time units configured by configuration signaling. For example, the third subset may be made up of all uplink, downlink and retention time units in the first subset.
Since the time units in the third subset cannot be covered by the SFI, a collision between configuration signaling and the SFI may occur if the SFI includes a configuration for any time unit in the third subset and is fully applied.
Even if the second subset comprises at least one first time unit belonging to the third subset, i.e. the SFI comprises a configuration of the first time unit(s), the SFI is not applied to the time units in the third subset, whereby conflicts between configuration signaling and the SFI can be reduced.
This embodiment may be combined with the embodiment associated with fig. 1. In this case, the SFI does not include the configuration of any time units in the third subset, and can be applied to all time units in the second subset.
In one example, if the SFI includes a configuration of the first time unit(s), the UE may skip the configuration of the first time unit(s). In another example, if the SFI includes a configuration of first time unit(s), the UE may impose a delay on the configuration of at least one first time unit and a time unit immediately following the first time unit(s) in the SFI so as to skip time units in the third subset, i.e., the UE may apply the configuration of the first time unit(s) and the time unit immediately following the first time unit(s) in the SFI to time units immediately following the first time unit(s) and not belonging to the third subset. If the SFI periodically configures time units in the second subset, the actual configuration period at the UE side may be different from the configuration period in the SFI due to the delayed configuration application. For example, the SFI may include a configuration of time slot a in the third subset, in which case the UE may apply the configuration of time slot a and the time slots immediately following time slot a to time slots immediately following time slot a and not belonging to the third subset.
Examples of configuration signaling and SFI will be described in more detail below with reference to fig. 3-9 of the drawings, and details common to the foregoing embodiments will not be described in detail. The configuration signaling and SFI may configure the time cell format within a configuration period. In fig. 3-9, each box represents a time slot, a horizontal line filled region represents a DL format, a vertical line filled region represents an UL format, a dot filled region represents an unconfigured format, a slash filled region represents a reserved format, a blank region represents an unknown time unit, a grid filled region represents a time resource of an SFI, and an arrow represents an SFI configuration.
Referring to fig. 3, in one example, there are 10 slots within a configuration period. The format of each slot is configured by configuration signaling as follows:
DL time unit: the first 2 slots + slot #3; UL time unit: the last time slot; unknown time units: time slots #2, #4, #5; retention time unit: slots #6 and #7; unconfigured time cell: slot #8.
In the configuration period, the first subset includes slots #0- #7, #9, and the third subset includes slots #0, #1, #3, #6, #7, #9.
At the top of the configuration signaling, the SFI is configured to indicate slots #4, #5 as UL and slot #8 as DL. The SFI may be applied to all configured symbols.
Referring to fig. 4, in another example, there are 10 slots within a configuration period. The format of each slot configured by the configuration signaling is the same as those in the upper part of fig. 3.
At the top of the configuration signaling, the SFI is configured to indicate slots #4, #5, #6 as UL and slot #8 as DL. Since the configuration signaling indicates slot #6 as reserved, the configuration of slot #6 in the SFI will not apply to slot #6 and will be ignored by the UE.
Referring to fig. 5, in yet another example, there are 10 slots within a configuration period. The format of each slot configured by the configuration signaling is the same as those in the upper part of fig. 3.
At the top of the configuration signaling, the SFI is configured to indicate slots #4, #5 as UL and slot #6 as DL. Since configuration signaling indicates slot #6 as reserved, the configuration of slot #6 in the SFI will apply to slot #8, but not slot #6.
Referring to fig. 6, in yet another example, there are 10 slots within a configuration period. The format of each slot is configured by configuration signaling as follows:
DL time unit: some symbols of first slot + slot #1, # 2; UL time unit: the last slot + some symbols of slot # 8; unknown/unconfigured time units: some symbols of slots #1, #2, #6, #8 and slots #3, #4, #5, #7; retention time unit: some symbols of slot 6.
In the configuration period, the first subset includes slots #0- #9 and the third subset includes symbols of slots #0, #9 and slots #1, #2, #6, # 8.
At the top of the configuration signaling, the SFI is configured to indicate some symbols of slots #4, #5, #7 as UL and some symbols of slot #8 as DL. The SFI may be applied to all configured symbols.
Referring to fig. 7, in yet another example, there are 10 slots within a configuration period. The format of each slot configured by the configuration signaling is the same as those in the upper part of fig. 6.
At the top of the configuration signaling, the SFI is configured to indicate some symbols of slots #4, #5, #7 as UL and some symbols of slots #6, #8 as DL.
Since some symbols of slot #6 are indicated as reserved by the configuration signaling, the configuration of some symbols of slot #6 in the SFI (intersecting reserved symbols) will not be applied and will be ignored by the UE.
Referring to fig. 8, in yet another example, there are 10 slots within a configuration period. The format of each slot configured by the configuration signaling is the same as those in the upper part of fig. 6.
At the top of the configuration signaling, the SFI is configured to indicate some symbols of slots #4, #5, #7 as UL and some symbols of slots #6, #7 as DL.
Since some symbols of slot #6 are indicated as reserved by the configuration signaling, the configuration of some symbols of slot #6 (intersecting reserved symbols) and subsequent symbols of slot #7 in the SFI will apply to the symbols immediately following the reserved symbols. The interval between the configuration in the SFI and the delayed configuration is the duration of the reserved symbol.
Referring to fig. 9, in yet another example, there are 10 slots within a configuration period. The format of each slot configured by the configuration signaling is the same as those in the upper part of fig. 6.
At the top of the configuration signaling, the SFI is configured to indicate some symbols of slots #4, #5, #7 as UL and some symbols of slots #6, #7 as DL.
Since some of the symbols of slot #6 are indicated as reserved by the configuration signaling, the configuration of some of the symbols of slot #6 (intersecting the reserved symbols) and the subsequent symbols of slot #7 in the SFI will apply to the symbols immediately following the reserved symbols, thus extending the actual configuration time of the SFI. The interval between the configuration of the reserved symbol and the subsequent symbol of slot #7 in the SFI and the delay configuration is equal to or greater than the slot.
Referring to fig. 10, fig. 10 is a schematic structural view of an apparatus for time cell configuration according to an embodiment of the present invention. The apparatus 100 may include a first transmission module 110 and a second transmission module 120.
