The resource scheduling method applied to the user terminal comprises the following steps: the user terminal sends resource scheduling change request information to network side equipment to request the network side equipment to carry out resource rescheduling and/or transmission mode adjustment. The technical scheme of the invention can reasonably utilize communication resources and the capability of the user terminal, effectively relieve the influence of harmonic interference/intermodulation interference possibly existing during uplink transmission in multi-connection or carrier aggregation on downlink reception of the UE, and improve user experience.
Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a resource scheduling method, a network side device, and a user terminal.
Background
In the future, the network not only supports carrier aggregation and multi-connection (including dual-connection) in the same system, but also supports multi-connection (including dual-connection) at a wireless side among different systems, and provides service for users. For a UE (User Equipment) with multiple transceivers, when multiple connections or carrier aggregation are performed, uplink multiple channels are transmitted simultaneously, which may improve throughput, but because the size of the UE is limited, as shown in fig. 1, harmonic interference, intermodulation interference, etc. may be generated, which may cause an impact on downlink reception of the UE.
Taking LTE (Long Term Evolution ) -NR (New Radio, new air interface) dual connection as an example:
1. when the UE uses 3.3GHz-3.4GHz of LTE B3 and NR, the four-order intermodulation interference generated by the simultaneous transmission of two uplink paths of the UE can influence the downlink reception of the UE at B3;
2. when the UE uses 3.4GHz-3.5GHz of LTE B3 and NR, the second harmonic of B3 may interfere with reception of the NR downlink (3420-3470);
3. when the UE uses 3.5GHz-3.6GHz of LTE B3 and NR, the interference of the downlink reception of B3 can be caused by the second-order intermodulation interference generated by the simultaneous transmission of the uplink two paths of the UE;
4. when the UE uses 3.5GHz-3.6GHz for LTE B8 and NR, the fourth harmonic of B8 can interfere with reception of the NR downlink (3556-3636).
Similarly, in other cases, the interference analysis may be performed according to the used frequency band, such as system dual connection, multi-connection, inter-system multi-connection, carrier aggregation, and the like.
However, these interferences may be tolerable to the UE in certain situations, such as when the UE is located in a cell center location, where the UE may continue to maintain multi-path transceiving. However, in some cases, such as when the UE is located at the edge of the cell and the channel quality is poor, the signal quality degradation is aggravated by these interferences and is difficult to be tolerated by the UE. According to the prior art, the network does not consider the tolerance degree of the interior of the UE to harmonic interference and intermodulation interference when configuring a transmission mode or transmission resources for the UE.
Because the network does not consider the tolerance degree of the interior of the UE to harmonic interference and intermodulation interference when configuring transmission resources or transmission modes for the UE which carries out carrier aggregation or multi-connection, the conditions of poor signal quality, link interruption and the like caused by the harmonic interference and the intermodulation interference when multipath transceiving occurs, and the user experience is influenced; or the UE can tolerate harmonic interference and intermodulation interference caused by multi-channel transceiving, but the network does not configure the UE with multi-channel transceiving to avoid the occurrence of the interference.

In this embodiment, after the network side device sends a resource scheduling change request function start instruction to the user terminal and sends resource scheduling change request information configuration to the user terminal, the user terminal may determine an internal interference condition under an existing transmission mode or resource use condition according to the configuration of the network side device and send corresponding resource scheduling change request information to the network side device, so that the network side device performs a scheduling decision of transmission resources, to reasonably utilize capabilities of communication resources and the user terminal, and effectively alleviate an influence of harmonic interference/intermodulation interference on UE downlink reception that may exist during uplink transmission in multi-connection or carrier aggregation, so as to improve user experience, and especially when the user terminal is located at a cell edge, ensure signal quality of the user terminal; and when the user terminal has stronger capability or better channel condition, the throughput is improved.
Further, the method further comprises:
and the network side equipment receives the resource scheduling change request information sent by the user terminal and carries out resource rescheduling and/or transmission mode adjustment on the user terminal.
In a specific embodiment, the rescheduling of resources and/or adjusting of transmission mode for the ue includes:
and the network side equipment adjusts the transmission mode of the user terminal to use a carrier aggregation or multi-connection mode for data transmission according to the resource scheduling change request information.
That is, the network side device determines, according to the resource scheduling change request information sent by the UE, that the UE wants the network side device to use carrier aggregation or multi-connection for data transmission. At this time, if the network side device has configured downlink multi/dual connection, the uplink is configured to be dual-transmission or multi-transmission by means of uplink transmission threshold adjustment and the like; if only one node serves the UE at this time, the node needs to add an SCG or an SCell as a primary node, and if the SCG is added, the primary node and the secondary node also need to perform negotiation for using resources.
Further, when the current transmission mode of the user terminal is a downlink multi/or dual connection mode, the network side device configures the uplink transmission mode of the user terminal into the multi/or dual connection mode through uplink transmission threshold adjustment; when only one node serves the user terminal currently, the network side device adds an SCG (secondary node) or an SCell (secondary cell) with the node as a primary node.
In another specific embodiment, the rescheduling of resources and/or adjusting of transmission mode for the user equipment includes:
and the network side equipment configures the user terminal to use a single carrier for transmission or close a certain uplink transmission channel of the user terminal according to the resource scheduling change request information.
That is, the network side device determines, according to the resource scheduling change request information sent by the UE, that the UE wants the network side device to use a single carrier for transmission in its configuration, or closes a certain uplink transmission channel.

the network side equipment heightens a reporting threshold of the uplink buffer storage amount of the user plane, so that the uplink data of the user terminal is only transmitted from a pre-configured main node link or an auxiliary node link; or simultaneously, the downlink data distribution of the user terminal is adjusted to enable the user terminal to use the same node as the uplink transmission, and the interference caused by ACK/NACK of the downlink data is avoided. For dual connectivity, when the downlink is MCG split bearer (master node split bearer), and the uplink adjusts the transmission from the master node link, the ratio between the downlink master node link and the slave node link may be adjusted to 100.

The following describes the resource scheduling method of the present invention in detail with reference to specific embodiments:
in the technical solution of the present invention, as shown in fig. 4, for a UE with multi-connection/carrier aggregation capability, the UE performs data transmission according to uplink and downlink transmission resources and a transmission mode (for example, whether to configure the UE through multi-carrier transmission) configured by a network side device, and according to resource scheduling change request information configuration (including a transmission cycle and a judgment condition) of the network side device, performs judgment according to a self channel condition, a processing capability and an internal interference condition, and if the judgment condition configured by the network side device is satisfied, transmits resource scheduling change request information to the network side device, and requests the network side device to perform resource rescheduling or adjustment of the transmission mode.
The network side equipment issues configuration for the UE and determines whether the UE starts a resource scheduling change request function, if the configuration is started, the network side equipment simultaneously configures specific signal quality indication for resource request change judgment and a sending period R of request information for the UE t Threshold1, threshold2 n ) Duration T, etc.Here, the UE signal quality may be referred to by RSRP, RSRQ, SINR, BLER, throughput, and other indicators. When the network side equipment starts the function for the UE, the UE judges the relation between the signal quality and the judgment threshold according to the sending period configured by the network side equipment, if the requirement of the threshold is met, a timer is started, when the duration time meeting the threshold exceeds the required duration configured by the network side equipment, the UE judges the relation between the time tr required by the uplink data to be sent and the changed transmission mode/resource scheduling time ts issued by the network side equipment, and if tr is judged>>ts, the UE sends resource scheduling change request information to the network side device.
The condition that the signal quality meets the threshold requirement means that if the signal quality is embodied by RSRP, RSRQ, SINR and throughput, the signal quality is equal to the current RSRP>Threshold1 or RSRP<Threshold2 n When the current time is short, the current time is considered to meet the threshold requirement; if BLER is taken as signal quality embodiment, RSRP<Threshold1 or RSRP>Threshold2 n It is considered to meet the threshold requirement.
Specifically, when the network side device starts a scenario in which the UE can send resource scheduling change request information, there are two types:
scene one: the UE with the multi-connection/carrier aggregation capability is configured on a single carrier or is transmitted and received through a single node according to network side equipment; or the UE downlink receiving adopts double receiving, and the uplink transmitting adopts single transmitting, for example, the UE supporting double connection receives data on LTE and NR frequency points at the same time, but only transmits uplink data on the LTE frequency point. When the UE sends the message according to the sending period configured by the network side equipment, every R t Time judges whether the quality of the received signal meets a Threshold1 configured by network side equipment, if the quality of the received signal meets the requirement that UE starts a timer T1, when the duration T1 of the signal quality greater than the Threshold exceeds a resource scheduling change triggering time T pre-configured by the network side equipment, the UE judges the time T required by uplink data to be sent r After the network side equipment is requested, the network side equipment issues the transmission mode change/resource scheduling time t s If t is r >>t s Then, the UE sends resource scheduling change request information to the network side device, and requests the network side device to use carrier aggregation or multi-connection for data transmission.
Scene two: and the UE with multi-connection/carrier aggregation capability performs data transmission in a carrier aggregation or multi-connection mode according to the configuration of the network side equipment.

For each receiver, the UE judges whether the received signal quality meets the Threshold of the network side equipment at intervals of Rt time according to the sending period configured by the network side equipment n (e.g., the LTE Threshold is Threshold 2) 1, The NR Threshold is Threshold2 2 ) If any one is satisfied, the UE starts a corresponding timer T2 n If a certain signal quality satisfies the threshold duration t2 n If the resource scheduling change trigger time T pre-allocated by the network side equipment is exceeded, the UE judges the time tr required by the uplink data to be sent n The relation of the ts and the modified transmission mode/resource scheduling time issued by the network side equipment is requested, if tr is n >>ts, the UE sends resource scheduling change request information to the network side device, requesting the network side device to use a single carrier for transmission of its configuration, or close a certain uplink transmission channel. Taking LTE-NR dual-connection UE as an example, if the LTE frequency point received signal quality continuously meets the threshold T2 1 And if the time exceeds T, the UE requests to close the uplink transmission on the NR frequency point, and only the LTE uplink transmission is reserved.
