Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, and a storage medium for signaling interaction between base stations.
Background
In the flexible duplex system, each cell can self-adaptively configure the uplink and downlink transmission directions of the cell time slot according to the service state in the cell. When adjacent cells configure different transmission directions in the same timeslot, as shown in fig. 1, a cell 1 is in a Downlink (DL) and a cell 2 is in an Uplink (UL), and Cross-link interference (CLI) is generated between the cells at this time. The CLI includes two types, inter-base station interference and inter-UE (User Equipment) interference. For inter-base station interference can be reduced by interference suppression technologies such as Advanced receiver (Advanced receiver), joint power control, etc., in order to reduce inter-UE interference, 3GPP (3rd Generation Partnership Project) conference determines that transmission direction information can be interactively preconfigured between base stations in a flexible duplex system. After the base station acquires the pre-configuration information of the adjacent cell, on one hand, interference source users and interfered users of the CLI can be determined, so that CLI measurement signals are reasonably configured; on the other hand, interference coordination scheduling can be performed between base stations, so that cross link interference between users is reduced or avoided.
The transmission direction configuration of the cell time slot includes three types, uplink transmission, downlink transmission and flexible transmission. The configuration mode of the transmission direction includes a semi-static configuration through RRC (Radio Resource Control) signaling and a dynamic configuration through physical layer signaling. The time slot or the symbol in the time slot, which is configured to be flexibly transmitted through the semi-static state of the RRC signaling, needs to dynamically indicate a specific uplink or downlink transmission direction through the physical layer signaling. If the interactive pre-configured transmission direction information between the base stations only contains semi-static transmission direction configuration, the base stations can not confirm whether CLI is generated or not and whether the users in the cell are interference source users or interfered users on the time slots or symbols indicated as flexible transmission in the semi-static state. If the information of the interactive pre-configuration transmission direction between the base stations contains physical layer signaling, the real-time performance of the interactive interface between the base stations is highly required, and frequent signaling interaction between the base stations is easily caused.

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
As shown in fig. 1, an implementation flow diagram of implementing the inter-base station signaling interaction method provided by the embodiment of the present invention for a receiving base station may include the following steps:
and S11, receiving the pre-configuration transmission direction information sent by the adjacent base station.
And the pre-configured transmission direction information comprises default transmission direction information of flexible transmission time domain resources configured for the coverage cell by the adjacent base station.
The signaling interaction method between the base stations provided by the embodiment of the invention can be implemented between adjacent base stations. In specific implementation, the pre-configured transmission direction information interacted between the adjacent base stations may include a first configuration information set and a second configuration information set, where the first configuration information set includes time domain resource transmission direction information periodically configured for the coverage cell by the adjacent base station, where the time domain resource transmission direction information includes transmission direction information of flexible transmission time domain resources, and the second configuration information set includes default transmission direction information configured for the flexible transmission time domain resources.
It should be noted that the time domain resource according to the embodiment of the present invention may include a time slot or an OFDM (Orthogonal Frequency Division Multiplexing) symbol, and the like, which is not limited in the embodiment of the present invention.
In specific implementation, the default transmission direction information configured for the UE in the second configuration information set does not notify the UE. The base station may indicate, through dynamic signaling, dynamic transmission direction information of a flexible transmission time domain resource configured for the UE in the coverage cell, where the dynamic transmission direction information may be the same as or different from default transmission direction information.
Based on this, the method for signaling interaction between base stations provided in the embodiment of the present invention may further include the following steps:
s12, indicating dynamic transmission direction information of flexible transmission time domain resources configured for the UE in the coverage cell through dynamic signaling; or indicating dynamic transmission direction information of the flexible transmission time domain resource of the UE in the coverage cell through dynamic signaling, wherein the dynamic transmission direction information is the same as the default transmission direction information.
In specific implementation, the time domain resource transmission direction information further includes transmission direction information of transmission time domain resources whose transmission directions are configured as uplink and downlink; and the second configuration information set also comprises default transmission direction information of time domain resources, the transmission direction of which is configured to be uplink or downlink in the first configuration set, and the default transmission direction information is the same as the transmission direction information configured in the first configuration information set. That is to say, in the second configuration information set, on the time domain resource configured by the periodic semi-static for the UE to perform uplink or downlink transmission, the default transmission direction configured by the base station for the time domain resource is consistent with the direction configured by the periodic semi-static, for example, on the time domain resource configured by the periodic semi-static for the UE to perform uplink transmission, the default transmission direction configured by the base station for the time domain resource should also be uplink transmission.
In addition, the periodic semi-static transmission direction configuration and/or the dynamic transmission direction indication of each cell are configured based on cell-specific (cell-specific) parameters, such as subcarrier spacing, transmission period of dynamic signaling, and the like. The different configurations of the cells also result in mismatch of the interaction information between the base stations. In view of this, in the embodiment of the present invention, the same subcarrier spacing and configuration period are used for the first configuration information set and the second configuration information set as those of the neighboring base stations. Or different subcarrier intervals and configuration periods are adopted for the first configuration information set and the second configuration information set and the adjacent base stations, but the time domain resource lengths indicated by the first configuration information set and the second configuration information set are the same.
In specific implementation, in order to reduce cross link interference between adjacent base stations, the method for signaling interaction between base stations according to the embodiment of the present invention may further include: and receiving coordinated scheduling configuration information sent by the adjacent base station, wherein the coordinated scheduling configuration information comprises a priority scheduling bandwidth range of the adjacent base station. That is, in the implementation of the present invention, the scheduling configuration information may be interacted and coordinated between the adjacent base stations through the Xn interface, wherein the scheduling configuration information includes the priority scheduling bandwidth range of the adjacent base station.
Based on this, when scheduling flexible transmission time-frequency resources for UE, if the default transmission direction of the scheduled flexible transmission time-domain resources is uplink and is different from the default transmission direction of the same time-domain resources of the adjacent base station, selecting frequency-domain resources from frequency-domain resources except the prior scheduling bandwidth range of the adjacent base station; or when flexible transmission time-frequency resources are scheduled for the UE, if the default transmission direction of the scheduled flexible transmission time-domain resources is downlink and is different from the default transmission direction of the same time-domain resources of the adjacent base station, selecting the frequency-domain resources from the frequency-domain resources in the bandwidth range which are preferentially scheduled by the base station.
For example, on the same time domain resource, when the default transmission direction configured by the base station # 1 for the UE in the coverage cell thereof is different from the default transmission direction configured by the neighboring base station # 2 for the UE in the coverage cell thereof, or the default transmission direction is the same on the time domain resource, but the transmission direction indicated by the base station # 1 through dynamic signaling is different from the default transmission direction of the neighboring base station # 2, for example, on the time domain resource, the transmission direction configured by the base station # 1 for the UE in the coverage cell thereof is uplink, in this case, the base station # 1 schedules the interference source user, and the base station # 1 may avoid the priority scheduling bandwidth range of the neighboring base station # 2 as much as possible according to the coordinated scheduling configuration information sent by the base station # 2; if the transmission direction of base station # 1 is downlink, in this case, base station # 1 schedules the interfered user, and base station # 1 may be scheduled preferentially within the priority bandwidth of base station # 1 according to the coordinated scheduling configuration information transmitted by base station # 2.
In specific implementation, the preconfigured transmission direction information and the coordinated scheduling configuration information may be interacted between adjacent base stations through an Xn interface.
Correspondingly, an embodiment of the present invention further provides a method for sending a base station to implement signaling interaction between base stations provided by the embodiment of the present invention, as shown in fig. 2, the method may include the following steps:
s21, sending pre-configuration transmission direction information to the adjacent base station, wherein the pre-configuration transmission direction information comprises the default transmission direction information of the flexible transmission time domain resource configured for the coverage cell.
In a specific implementation, the preconfigured transmission direction information may include all the default transmission direction information of the flexible transmission time domain positions, or may include some of the default transmission direction information of the flexible transmission time domain positions.
The preconfigured transmission direction information includes a first configuration information set and a second configuration information set, the first configuration information set includes time domain resource transmission direction information configured periodically for a coverage cell, the time domain resource transmission direction information includes transmission direction information of flexible transmission time domain resources, and the second configuration information set includes default transmission direction information configured for the flexible transmission time domain resources.
Optionally, the time domain resource transmission direction information further includes transmission direction information of transmission time domain resources whose transmission directions are configured as uplink and downlink; and the second configuration information set further includes default transmission direction information of time domain resources, the transmission direction of which is configured as uplink or downlink in the first configuration set, and the default transmission direction information is the same as the transmission direction information configured in the first configuration information set.
Optionally, the same subcarrier spacing and configuration period are used for the first configuration information set and the second configuration information set as the adjacent base station.
Optionally, different subcarrier intervals and configuration periods are adopted for the first configuration information set and the second configuration information set and the neighboring base stations, but the time domain resource lengths indicated by the first configuration information set and the second configuration information set are the same.
Optionally, the method for signaling interaction between base stations implemented by a sending base station may further include the following steps:
and S22, sending the coordinated scheduling configuration information to the adjacent base station.
Wherein the coordinated scheduling configuration information includes a priority scheduling bandwidth range of the local base station.
For a better understanding of the embodiments of the present invention, the following description will be given with reference to specific embodiments.
The first embodiment, the subcarrier spacing and the configuration period are the same.
The preconfigured transmission direction information interacted between adjacent base stations through the Xn interface includes the semi-static timeslot structure configuration in fig. 3a and the default transmission direction configuration in fig. 3 b. When the transmission direction information is interactively preconfigured between the base stations through the Xn interface, the same subcarrier interval (namely the length of the OFDM symbols is consistent) and the same configuration period are adopted for the semi-static transmission direction configuration and the default transmission direction configuration, and the two configuration periods are 5 slots (time slots).
As can be seen from fig. 3a, slot #0 (slot #0) of cell #1 (cell #1) is configured as downlink transmission (D), slots # 1, slot # 2, and slot # 3 are configured as flexible transmission directions (X), and slot # 4 is configured as uplink transmission (U). Slot #0 (slot #0) of cell # 2 is configured for downlink transmission (D), slot # 1, slot # 2, and slot # 3 are configured for flexible transmission directions, and slot # 4 is configured for uplink transmission (U).
As can be seen from fig. 3b, for 3 slots configured as flexible transmission directions, the base station # 1 indicates that the default transmission directions of the flexible transmission slots slot # 1 to slot #3 in the cell # 1 are DDU, and the base station # 2 indicates that the default transmission directions of the flexible transmission slots slot # 1 to slot #3 in the cell # 2 are DUU, wherein different patterns are adopted for the default transmission directions of the flexible transmission time domain positions; meanwhile, the base stations exchange the priority scheduling bandwidth range through an Xn interface, as shown in fig. 3c, BW # 1 corresponds to the priority bandwidth range of cell # 1, and BW # 2 corresponds to the priority scheduling bandwidth range of cell # 2.
As can be seen from fig. 3b, the default transmission directions of cell # 1 and cell # 2 on slot # 2 are different, where the uplink transmission user in cell # 2 may generate inter-UE interference to the downlink reception user in cell # 1, as shown by UE2 and UE1 in fig. 1. After the base station of the cell # 1 receives the default transmission direction configuration information of the base station of the cell # 2, knowing that the inter-UE interference exists on the slot # 2 and that the user UE1 in the cell is an interfered user, when scheduling the downlink transmission resource of the UE1, preferentially selecting the bandwidth resource in the BW # 1; after the base station of cell # 2 receives the default transmission direction configuration of the base station of cell # 1, knowing that there is inter-UE interference on slot # 2 and that the UE2 in the cell is an interference source user, the base station of cell # 2 avoids the bandwidth resource of BW # 1 as much as possible when scheduling the uplink transmission resource of UE 2.
The second embodiment, the subcarrier spacing and the configuration period are different.
The preconfigured transmission direction information interacted between the base stations through the Xn interface includes the semi-static transmission direction configuration in fig. 4a and the default transmission direction configuration in fig. 3 b; when pre-configuring transmission direction information interactively through an Xn interface between base stations, configuring a semi-static transmission direction by adopting a smaller subcarrier interval (namely a longer OFDM symbol length), wherein the configuration period is 5 slots; the default transmission direction configuration adopts a larger subcarrier interval (namely, a shorter OFDM symbol length), and the period is 10 slots; the time domain resources indicated by the two configuration sets are of the same length.
The configuration of the semi-static slot structures of cell # 1 and cell # 2 is shown in fig. 4a, where slot # 0 is downlink transmission, slots # 1 to #3 are flexible transmission, and slot # 5 is uplink transmission; as shown in fig. 4b, the default transmission directions of the flexible transmission slots slot # 2 to slot #7 are indicated as DDDDUU in both the cell # 1 and the cell # 2;
the base stations exchange the priority scheduling bandwidth range through the Xn interface, as shown in fig. 4c, wherein BW # 1 corresponds to the priority bandwidth range of cell # 1, and BW # 2 corresponds to the priority bandwidth range of cell # 2.
In an embodiment, as can be seen from fig. 4b, the default transmission directions of cell # 1 and cell # 2 configured in slot # 4 and slot # 5 are the same, and both are downlink. However, the actual transmission direction of the cell # 2 indicated by the dynamic signaling is changed into uplink, as shown in fig. 4d, the uplink transmission user in the cell # 2 may generate inter-UE interference to the downlink reception user in the cell # 1, as shown by the UE2 and the UE1 in fig. 1. At this time, if the cell # 2 base station knows that inter-UE interference occurs in slot # 4 and slot # 5, and the UE2 in the cell is an interference source user, the base station avoids the bandwidth resource of BW # 1 as much as possible when scheduling uplink resource transmission of UE 2.
In another embodiment, as can be seen from fig. 4b, the default transmission directions of cell # 1 and cell # 2 configured in slot # 6 and slot # 7 are the same, and both are uplink. However, the actual transmission direction of the cell # 1 indicated by the dynamic signaling is changed into downlink, as shown in fig. 4d, the uplink transmission user in the cell # 2 may generate inter-UE interference to the downlink receiving user in the cell # 1, as shown by the UE2 and the UE1 in fig. 1. At this time, if the cell # 1 base station knows that inter-UE interference occurs in slot # 6 and slot # 7, and the UE1 in the cell is an interfered user, the bandwidth resource of BW # 1 is preferentially selected when scheduling downlink resource transmission of UE 1.
In the inter-base-station signaling interaction method, apparatus, and storage medium provided in the embodiments of the present invention, by including default transmission direction information of flexible transmission time domain resources configured for a coverage cell in signaling interacted between base stations, when a base station schedules resources for a coverage cell, it can pre-determine in advance whether there is cross link interference according to default transmission direction information configured for UE in its coverage cell by other base stations on the same time domain resources. Furthermore, the prior scheduling bandwidth range can be interacted between adjacent base stations, so that interference coordination scheduling can be realized between the base stations, and when cross link interference exists between the adjacent cells, the scheduling of interference UE on the same time domain resource is avoided, so that the interference level between the UE is reduced. In addition, when the transmission direction is interactively preconfigured between the base stations, the same subcarrier interval and configuration period are adopted, so that the matching of the time domain resource lengths of the interactive information between the base stations can be ensured, and the occurrence of unconfigured time slots or symbols is avoided.
Based on the same inventive concept, the embodiment of the invention also provides a signaling interaction device between base stations, and as the principle of the device for solving the problems is similar to the signaling interaction device between the base stations, the implementation of the device can refer to the implementation of the method, and repeated parts are not repeated.
