Referring to
In the embodiment of the present disclosure, the first system and the second system may be tightly coupled in a Dual Connectivity (DC) mode. One system acts as a master node (MN) and the other system acts as a secondary node (SN). In a dual-connected system, two cell groups are included, which are a master cell group (MCG) and a secondary cell group (SCG). The primary cell group may include a primary cell (PCell) and one or more secondary cells (SCells), and the secondary cell group may include a primary and secondary cell (PSCell), and one or more SCells.
In the above network system, the UE 11 may perform a data transmission with the first base station 12 and the second base station 13 at the same time, or may perform a data transmission with the first base station 12 and the second base station 13 at different times, which is not limited in the embodiment of the present disclosure.
Referring to
Step 201: receiving a Time Division Multiplexing (TDM) pattern sent by a base station, where the TDM pattern is configured to indicate an uplink resource and/or a downlink resource available for the UE, and the base station is a serving base station of the UE.
It should be noted that, the base station may be a first base station or a second base station in the transmission control system shown in
The above TDM pattern can be understood to indicate to the UE that the uplink and downlink of the frequency band combination that will generate a harmonic interference do not work simultaneously, and/or the LTE uplink, the LTE downlink and the NR downlink of the frequency band combination that generates an intermodulation interference do not work simultaneously. Optionally, the above TDM pattern may be a set of binary characters, for example: [10101010], the [10101010] may indicate that the UE that receives the signaling can only transmit in Slot 0, 2, 4 and 6, that is, indicate that the available uplink resources of the UE are Slot 0, 2, 4 and 6.
The above TDM pattern can realize that the uplink and downlink of the frequency band combination where the UE will generate the harmonic interference do not work at the same time, and the uplink and downlink of the frequency band combination where the UE will generate the intermodulation interference do not work at the same time. For example, the TDM pattern may be a TDM pattern generated by the base station to avoid intra-UE interference from the UE. For example, the TDM pattern may be generated by the base station according to a scheduling result of the second base station for the UE. For the harmonic interference shown in
Optionally, in the embodiment of the present disclosure, the uplink resource may be an uplink slot, and the downlink resource may be a downlink slot, or the uplink resource may be an uplink physical resource block (PRB), and the downlink resource may be a downlink PRB. The uplink PRB and the downlink PRB may avoid the intra-UE interference of the UE. For example, the uplink and downlink of the UE are configured through the above-mentioned TDM pattern to transmit in a PRB that does not interfere with each other. Of course, in some embodiments, the uplink resource may also be an uplink subframe, and the downlink resource may be a downlink subframe.
Step 202: performing a transmission control according to the TDM pattern.
In, Step 202, the transmission may be performed on the uplink resource and/or the downlink resource indicated by the TDM pattern, so as to effectively avoid self-interference of the terminal and improve the transmission performance of the UE. Certainly, in some scenarios, the transmission may also be performed on resources other than the uplink resources and/or downlink resources indicated by the TDM pattern according to the above TDM pattern, which is not limited in this embodiment of the present disclosure.
In this embodiment, by receiving a TDM pattern sent by a base station and performing a transmission control according to the TDM pattern, it is able to effectively avoid the intra-UE interference and improve the transmission performance of the UE.
Referring to
Step 501: receiving the TDM pattern which is sent by the base station through one or more of a Radio Resource Control (RRC) signaling, a Media Access Control (MAC) Control Unit (CE) and a physical downlink control channel, where the TDM pattern is configured to indicate an uplink resource and/or a downlink resource available for the UE, and the base station is a serving base station of the UE.
The receiving the TDM pattern through the above multiple items may be transmitting part of the content of the TDM pattern in each of the above.
In addition, it should be noted that in this embodiment, step 501 is optional, that is, in this embodiment, the TDM pattern is not limited to be transmitted through the above RRC signaling, MAC CE, or PDCCH. The above TDM pattern may also be transmitted through a user dedicated signaling.
Optionally, the TDM pattern is configured to indicate a ratio of the uplink resource and the downlink resource;
or,
the TMD pattern is configured to indicate a position of the uplink resource and/or the downlink resource within one period.
In this embodiment, the above-mentioned TDM pattern may be configured similar to the uplink and downlink slots allocation ratio of Time Division Duplexing (TDD), for example, the ratio of the downlink and uplink slots is 3:1.
In addition, the configuration mode similar to the Multicast Broadcast Single Frequency Network (MBSFN) may also be used to configure the above TDM pattern, for example, several slots are set as available uplink slots or available downlink slots every 40 ms period.
In this embodiment, the flexibility of the TDM pattern configuration may be improved through the above two methods.
Step 502: performing a transmission control according to the TDM pattern.
Optionally, the performing the transmission control according to the TDM pattern includes:
in the case that the UE receives Downlink Control Information (DCI) of an uplink (UL) grant and an uplink resource indicated by the DCI conflicts with the uplink resource indicated by the TDM pattern, cancelling performing a scheduling result of the UL grant;
and/or
in the case that the UE receives DCI of a downlink (DL) grant and a downlink resource indicated by the DCI conflicts with the downlink resource indicated by the TDM pattern, cancelling performing a scheduling result of the DL grant;
and/or
in the case that an uplink resource scheduled by a UL grant transmitted on a target downlink resource conflicts with the uplink resource indicated by the TDM pattern, cancelling a blind detection for the UL grant on the target downlink resource;
and/or
in the case that a downlink resource scheduled by a DL grant transmitted on the target downlink resource conflicts with the downlink resource indicated by the TDM pattern, cancelling a blind detection for the DL grant on the target downlink resource.
The DCI of the UL grant and the DL grant are sent by the base station. In addition, the uplink resource conflicting with the uplink resource indicated by the TDM pattern includes:
the uplink resource is not within the uplink resource available for the UE which is indicated by the TDM pattern;
the downlink resource conflicting with the downlink resource indicated by the TDM pattern includes:
the downlink resource is not within the downlink resource available for the UE which is indicated by the TDM pattern.
For example, the uplink slot or uplink subframe indicated by the DCI of the UL grant is not in the uplink slot or uplink subframe available for the UE indicated by the TDM pattern; or
The downlink slot or downlink subframe indicated by the DCI of the DL grant is not in the downlink slot or downlink subframe available for the UE indicated by the TDM pattern.
In this embodiment, the scheduling result of the DL grant or UL grant that conflicts with the above TDM pattern may not be executed, and the DL grant or UL grant is considered to be a false report, so that the intra-UE interference may be avoided.
For example, for the harmonic interference, the LTE base station provides a UL TDM pattern (such as [10101010]) to the above-mentioned UE served by the LTE base station, where [10101010] represents that the UE receiving the signaling may only perform a transmission at Slot 0, 2, 4 and 6. The NR base station may send the DL TDM pattern (such as [01010101]) to the above-mentioned UE served by the NR base station, where [01010101] represents that the UE receiving the signaling may only perform a reception at Slot 1, 3, 5 and 7.
In this way, the CRC check of the PDCCH sent by the LTE base station received by the UE is successfully, but the UL slot indicated by the DCI of the UL grant transmitted by the PDCCH conflicts with the TDM pattern. For example, the UE receives DCI of the UL grant indicating that the UE performs a transmission at Slot 1, 3, 5 and 7, that conflicts with the TDM pattern indicating that the UE may only perform a transmission at the Slot 0, 2, 4 and 6, so the UE skips this UL grant.
If the CRC check of the PDCCH sent by the NR base station received by the UE is successfully, but the DCI of the DL grant transmitted by the PDCCH indicates that the UE performs a reception at Slot 0, 2, 4 and 6, that conflicts with the TDM pattern indicating that the UE may only perform a reception at Slot 1, 3, 5 and 7, so the UE skips this DL grant.
For another example, for the intermodulation interference, the LTE base station provides a UL TDM pattern (such as [11110000]) to the UE served by the LTE base station, where [11110000] indicates that the UE receiving the signaling may only perform a transmission at Slot 0, 1, 2 and 3.
The NR base station sends the UL TDM pattern (such as [00001111]) to the UE served by the NR base station, where [00001111] represents that the UE receiving the signaling may only perform a transmission at Slot 4, 5, 6 and 7.
If the UE receives the UL grant sent by the LTE base station which indicates that the UE performs the transmission at Slot 4, 5, 6 and 7, that conflicts with the TDM pattern indicating that the UE may only perform a transmission at Slot 0, 1, 2 and 3, so the UE skips this UL grant.
If the UE receives the UL grant sent by the NR base station which indicates that the UE performs the transmission at Slot 0, 1, 2 and 3, that conflicts with the TDM pattern indicating that the UE may only perform a transmission at Slot 4, 5, 6 and 7, so the UE skips this UL grant.
In addition, in the above embodiments, the uplink resource scheduled by the UL grant transmitted on the target downlink resource conflicts with the uplink resource indicated by the TDM pattern, which may refer to that the UE predicts that the uplink resource scheduled by the UL grant transmitted on the above target downlink resource conflicts with the uplink resource indicated by the TDM pattern. For example, the UE may predict, based on a default UL grant uplink slot or downlink slot scheduling rule, whether the uplink resource scheduled by the UL grant transmitted on the downlink resource conflicts with the uplink resource indicated by the TDM pattern. If so, the blind detection of the UL grant may not be performed on the target downlink resource, thereby saving the power consumption of the UE and avoiding the intra-UE interference.
For the case that the downlink resource scheduled by the DL grant transmitted on the target downlink resource conflicts with the downlink resource indicated by the TDM pattern, reference may be made to the case that the downlink resource scheduled by the UL grant transmitted on the target downlink resource conflicts with the downlink resource indicated by the TDM pattern, which is not repeated herein. In addition, in this embodiment, the search space for the blind detection of UL grant or DL grant on a certain slot is independent, for example, resources of the search space are orthogonal or partially overlap.
For example, for the harmonic interference, it is assumed that the blind detection areas of UL grant or DL grant on some slots are independent, and the UL slots or DL slots scheduled by the UL grants or DL grants transmitted on these DL slots conflict with the TDM pattern, then the UE does not perform a blind detection on the UL grants or DL grants on these DL slots, that is, in these DL slots, the UE skips the blind detections of the UL grants or DL grants.
For another example, for the intermodulation interference, it is assumed that the blind detection areas of UL grants or DL grants on some slots are independent, and the UL slots scheduled by the UL grants transmitted on these DL slots conflict with the TDM pattern, then the UE does not perform a blind detection on the UL grants on these DL slots, that is, in these DL slots, the UE skips the blind detections of the UL grants.
Optionally, subsequent to receiving the TDM pattern sent by the base station, the method further includes:
turning off a radio frequency module circuit and/or a baseband module circuit of a transmitter according to the TDM pattern, where the radio frequency module circuit is all or a part of the radio frequency module circuit of the transmitter;
and/or
turning off a radio frequency module circuit and/or a baseband module circuit of a receiver according to the TDM pattern, where the radio frequency module circuit is all or a part of the radio frequency module circuit of the receiver.
The radio frequency module circuit of the turned-off transmitter may be one or more of a power amplifier (PA) and a filter. The RF module circuit of the turned-off receiver may be one or more of a low noise amplifier (LNA) and a filter.
It may be determined which slots do not need to be transmitted according to the above TDM pattern, and then the RF module circuit and/or the baseband module circuit of the transmitter are turned off at the corresponding slot, thereby saving the power consumption of the UE. Similarly, the RF module circuit and/or the baseband module circuit of the receiver may be turned off, so as to further save the power consumption of the UE.
Of course, subsequent to the turning off the radio frequency module circuit and/or the baseband module circuit of the transmitter according to the TDM pattern, the method further includes:
starting in advance the radio frequency module circuit and/or the baseband module circuit of the transmitter according to the TDM pattern and a preset time, where the preset time is a warm-up time of the radio frequency module circuit and/or the baseband module circuit of the transmitter, and the radio frequency module circuit is all or a part of the radio frequency module circuit of the transmitter;
subsequent to the turning off the radio frequency module circuit and/or the baseband module circuit of the receiver according to the TDM pattern, the method further includes:
starting in advance the radio frequency module circuit and/or the baseband module circuit of the receiver according to the TDM pattern and a preset time, where the preset time is a warm-up time of the radio frequency module circuit and/or the baseband module circuit of the receiver, and the radio frequency module circuit is all or a part of the radio frequency module circuit of the receiver.
For example: the warm-up time of the RF module circuit and/or the baseband module circuit of the transmitter is 5 um, then the RF module and/or the baseband module circuit is turned on at least 5 um before the uplink transmission slot. For another example: the warm-up time of the RF module circuit and/or the baseband module circuit of the receiver is 5 um, then the RF module and/or the baseband module circuit is turned on at least 5 um before the downlink receiving slot.
The above warm-up time may be understood as the period from turning on the transmitter or receiver's radio frequency module circuit and/or baseband module circuit starts to the time when they can work normally. Through the above TDM pattern and preset time, it is able to save the power consumption of the UE, ensure that the UE may accurately receive and send data, so as to improve the performance of the UE.
In addition, in this embodiment, the above method may further include the following steps:
receiving a TDM pattern sent by a second base station, where the TDM pattern is configured to indicate an uplink resource and/or a downlink resource available for the UE, and the second base station is a serving base station of the UE; and
