Description

Indication method and device of dynamic time slot format information, base station and user equipment
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for indicating dynamic timeslot format information, a base station, and a user equipment.
Background
The Slot Format Information (SFI) is a broad concept, and there are two types, one is dynamically configured by semi-static RRC (Radio Resource Control) signaling, that is, semi-static SFI; one is carried on a GC-PDCCH (group-common Physical Downlink Control Channel) and is dynamically sent to a group of UEs (User equipments), that is, dynamic timeslot format information (dynamic SFI).
The SFI information carried on the GC-PDCCH may indicate a format of one or more slots (slots). After the UE monitors the SFI, it can know which symbols in the timeslot are "UL (uplink)", which symbols are "DL (downlink)", and which symbols are "unknown".
The SFI carries an index that points to a table configured to the UE through RRC signaling.
Numerology is a concept related to frame structure configuration in a 5G NR (New Radio, New air interface) physical layer protocol, and refers to Cyclic Prefix (CP) length and SubCarrier Spacing (SCS). Since the slot structure is related to numerology, SFI is related to numerology.
In the 5G NR, multiple different partial Bandwidths (BWPs) may be configured for the UE through RRC signaling, and in the BWP configuration, the cyclic prefix length and the subcarrier spacing are included, and the numerology of different BWPs may be the same or different. In addition, in a Carrier aggregation scenario, different Component Carriers (CCs) may have different numerology and different uplink and downlink configurations. When one dynamic slot format information indication (dynamic SFI indication) is used for multiple fractional bandwidths and/or multiple member carriers, the problem of how to indicate multiple different numerologies needs to be solved.
One prior art scheme employs a reference numerology (indicated by the network) from which slot formats for different numerologies are derived from the slot formats indicated by the SFI. Another solution is to obtain the slot format of the target BWP according to the numerology of the resource where the SFI is located, which is essentially equivalent to taking the numerology of the resource where the SFI is located as the reference numerology.
These two schemes, while capable of indicating different numerology slot formats, do not address the issues of different numerology alignment and cross-link interference.

An embodiment of the present invention provides a method for indicating dynamic timeslot format information, where the method is applied to a base station, and as shown in fig. 2, the method includes:
s21, configuring a multi-dimensional table for the user equipment through RRC signaling, wherein the dimension of the multi-dimensional table is determined by the number of indexes, the number of partial bandwidths and the number of component carriers, and each entry in the table is a slot format pattern with the same time length.

S22, sending slot format information to the user equipment through the GC-PDCCH, where the slot format information carries an index, so that the user equipment obtains, according to the index, a slot format pattern corresponding to each activated partial bandwidth of each component carrier from the table.
The method for indicating dynamic time slot format information provided by the embodiment of the invention configures a multidimensional table for user equipment through RRC signaling, wherein the dimensionality of the multidimensional table is determined by the number of indexes, the number of partial bandwidths and the number of member carriers, each entry in the table is a time slot format pattern with the same time length, the user equipment monitors a GC-PDCCH according to a monitoring period, the time slot format information carried on the GC-PDCCH carries the indexes, and the user equipment respectively acquires the time slot format patterns corresponding to each activated partial bandwidth of each member carrier from the table according to the indexes. Because different time slot format patterns in a table configured for the user equipment by the base station have the same time length, the problem of alignment of different parameter sets is solved; the base station selects a proper time slot format pattern through RRC signaling configuration and dynamic time slot format information indication, and can effectively solve the problem of cross-link interference.
The following describes the method for indicating dynamic timeslot format information according to the present invention in detail with reference to specific embodiments.
Assuming that the monitoring period of the GC-PDCCH is 1ms, the UE works in a carrier aggregation scene. The UE has 2 component carriers, denoted CC1 and CC2, respectively. CC1 has 2 BWPs, represented by CC1_ BWP1 and CC1_ BWP2, where the subcarrier spacing for CC1_ BWP1 is 15kHz and the subcarrier spacing for CC1_ BWP2 is 30 kHz; CC2 has 1 BWP, denoted by CC2_ BWP1, where the subcarrier spacing for CC2_ BWP1 is 15 kHz.
And the UE monitors the GC-PDCCH according to the monitoring period, and the index carried in the time slot format information carried on the GC-PDCCH points to a multidimensional table.
The dimensionality of the table is determined by the number of indexes, the number of partial bandwidths and the number of member carriers. The number of the partial bandwidths is the sum of all downlink partial bandwidths and all uplink partial bandwidths configured for the UE by the RRC signaling, and each member carrier corresponds to one partial bandwidth number in a carrier aggregation scene.
In this embodiment, CC1 has 2 BWPs, and CC2 has 1 BWP, so the number of fractional bandwidths corresponding to the table is equal to the maximum of the number of fractional bandwidths corresponding to all component carriers, that is, the number of BWPs corresponding to the table is 2. In this embodiment, the dimension of the table is N × 2, where N is configured by RRC signaling and represents the first dimension of the table, i.e., the number of indexes.
Each entry in the table is a slot format pattern having the same length of time. Since the monitoring period of the GC-PDCCH is 1ms, the length of each slot format pattern in the table is 1 ms. Specifically, the slot format pattern corresponding to BWP1 includes 1 slot with length of 1ms, the slot format pattern corresponding to BWP2 includes 2 slots with length of 0.5ms, and the slot format pattern corresponding to BWP3 includes 1 slot with length of 1 ms.
The UE obtains a slot format pattern corresponding to each activated partial bandwidth of each component carrier from the table, respectively. The UE knows which partial bandwidths are available for the UE and which member carriers are aggregated for the UE, and after monitoring the dynamic time slot format information, the UE searches a corresponding time slot format pattern in a table configured for the UE through RRC signaling according to an index (index) indicated by the dynamic time slot format information, the partial bandwidths of the UE and the member carriers aggregated for the UE, so that the UE can know which symbols in the current and future time slots are UL, DL and unsmunwn.
For example, when the index indicated by the dynamic slot format information is index ═ n, CC1_ BWP1 corresponds to the slot format pattern in the table as shown in fig. 3. CC1_ BWP2 corresponds to the slot format pattern in the table as shown in FIG. 4. CC2_ BWP1 corresponds to the slot format pattern in the table as shown in FIG. 5.
In fig. 3, 4, and 5, a symbol shaded with a slash is "DL", a symbol shaded with a box is "UL", and an unshaded symbol is "un-shaded".
It should be noted that, when the base station configures the slot format pattern in the table through RRC signaling, not all entries in the table have the slot format pattern. For example, in this embodiment, CC1 has 2 BWPs, CC2 has 1 BWP, and the dimension of the table is N × 2, and it can be seen that since there is no CC2_ BWP2, CC2_ BWP2 has no corresponding slot format map sample in the table, so a default value can be adopted when configuring the table.
In particular, for non-carrier aggregation scenarios (i.e., only one serving cell), if the UE has only one partial bandwidth, the table of dynamic slot format information degenerates to one dimension.
An embodiment of the present invention further provides an apparatus for indicating dynamic timeslot format information, where the apparatus is located in a user equipment, and as shown in fig. 6, the apparatus includes:
