Detailed Description
In practical applications, coverage is more limited in the uplink direction than in the downlink direction, and therefore the 5G NR standard also supports the SUL technology. On the one hand, the method of re-ploughing 900/1800/F/A/E into 5G frequency band and adopting a full uplink frequency spectrum SUL is considered to carry out uplink enhancement, and on the other hand, the method of time division duplex (TDD, time Division Duplexing) +SUL is considered to carry out uplink enhancement on the existing frequency or potential frequency of 5G, such as 4.9GHz/6 GHz/millimeter wave and the like. In the related protocol of 5G NR, the SUL carrier is defined in association with a conventional carrier pair including uplink and downlink, and SUL carrier selection is mainly based on SSB. In idle state, the association relation between 4.9GHz NR and 2.3GHz SUL is configured and selected through broadcasting a system information block (SIB, system Information Block) 1 message or a radio resource control (RRC, radio Resource Control) reconfiguration message, and the SUL related information is sent to the terminal, including information of a Physical Random access channel (PRACH, physical Random ACCESS CHANNEL), a Physical Uplink control channel (PUCCH, physical Uplink Control Channel) and a Physical Uplink shared channel (PUSCH, physical Uplink SHARED CHANNEL) characterizing the SUL. In the connected state, in combination with measurement control of the A1 event or the A2 event, the terminal is instructed to switch to the UL carrier or the SUL carrier through downlink control information (DCI, downlink Control Information). Wherein if the corresponding A1 measurement event, i.e. the measurement result based on NR downlink reference signal received Power (RSRP, reference Signal Receiving Power) is greater than a given threshold, then the uplink is on the SUL carrier; if the corresponding A2 measurement event, i.e. based on NR downlink RSRP measurement results, is smaller than a given threshold, the uplink is on the UL carrier. That is, in the related art, the terminal mainly performs SUL carrier selection based on RSRP of the SSB in the idle state and the connected state, however, since the SUL carrier has no corresponding downlink carrier, the problem of inaccurate SUL carrier selection is caused, and thus additional uplink interference lifting is introduced, so that uplink performance is lost.
Based on the above, the embodiment of the application provides a method, a device, a terminal and a storage medium for selecting uplink carriers. When a terminal is in an idle state, selecting to access an SUL carrier or an UL carrier based on a first threshold, wherein the first threshold is determined based on at least one of a 5QI and a slice identifier corresponding to a service type of the first terminal; and when the first terminal is in a connection state and is in an NR uplink time slot, selecting to switch to the SUL carrier or the UL carrier in the first cell accessed by the first terminal based on at least one of a measurement result of the SUL carrier of the first cell, a measurement result of the UL carrier of the first cell and a first load corresponding to the SUL carrier of the first cell or a second load corresponding to the UL carrier of the first cell.
The embodiment of the application provides a method for selecting uplink carriers, which is applied to a first terminal, as shown in fig. 1, and comprises the following steps:
step 101: and when the first terminal is in an idle state, selecting to access an SUL carrier or an UL carrier based on a first threshold.
The first threshold is determined based on at least one of a 5QI and a slice identifier corresponding to the service type of the first terminal.
In practical application, different service types are determined through parameters of one or more dimensions. Specifically, the parameters that determine the traffic type include, but are not limited to: service priority, transmission rate requirement of service, reliability requirement of service, time delay requirement of service, service type, service access reason, terminal transmitting power allowance, terminal downlink signal quality and the like. In actual application, a mapping relation table of one or more dimension parameters and corresponding service types is established, and the service type of the first terminal is determined based on the mapping relation table.
Here, different service types correspond to different access thresholds of uplink carriers, and in the case that the first terminal is in an idle state, the uplink carrier meeting the corresponding access threshold is selected based on the access threshold corresponding to the service type of the first terminal. After determining the service type of the first terminal, an access threshold corresponding to the service type is determined based on the requirement of the service type on quality of service (QoS, quality of Service).
Based on this, in an embodiment, the first threshold is determined based on at least one of:
5QI corresponding to the service type;
Slice ID corresponding to the service type.
Where 5QI is a scalar defined in the third generation partnership project (3GPP,3rd Generation Partnership Project) protocol and the 5QI corresponding to the traffic type is used to point to the 5G QoS characteristics required by the traffic type. The network slice is a network which cuts a physical network into a plurality of virtual end-to-end networks, each network slice can obtain logically independent network resources, and each network slice can be mutually insulated. Depending on the QoS required for the traffic type, such as low latency, high throughput, connection density, spectral efficiency, traffic capacity or network efficiency, network slices capable of supporting the corresponding QoS, i.e. traffic slices, are configured for each type of traffic type, wherein each network slice corresponds to a slice Identification (ID).
From the above, it can be seen that, whether the service type corresponds to the 5QI or the slice identifier, the QoS required by the service can be reflected, so in this embodiment, the access threshold, that is, the first threshold, of the uplink carrier corresponding to the service type can be determined based on the 5QI corresponding to the service type and/or the slice identifier corresponding to the service type, so that the uplink carrier selected based on the service type of the first terminal can meet the QoS requirement corresponding to the service type, thereby improving the matching between the uplink carrier and the service type, and improving the uplink performance.
Step 102: and when the first terminal is in a connection state and is in a wireless new air interface NR uplink time slot, selecting to switch to a SUL carrier or a UL carrier in a first cell accessed by the first terminal based on a first measurement result, a second measurement result and first information.
Wherein the first measurement characterizes a measurement of a SUL carrier for the first cell; the second measurement characterizes a measurement of an UL carrier for the first cell; the first information characterizes at least one of a first load corresponding to a SUL carrier of the first cell or a second load corresponding to a UL carrier of the first cell.
Here, the SUL carrier and the UL carrier of the first cell to which the first terminal accesses are measured, for example, a signal to interference plus noise ratio (SINR, signal to Interference plus Noise Ratio) of a channel Sounding reference signal (SRS, sounding REFERENCE SIGNAL) of the SUL carrier or the UL carrier is measured, to obtain a first measurement result corresponding to the SUL carrier and a second measurement result corresponding to the UL carrier. And on the basis of obtaining the first measurement result and the second measurement result, combining a first load corresponding to the SUL carrier of the first cell and/or a second load corresponding to the UL carrier of the first cell, and determining to select the SUL carrier or the UL carrier of the first cell to be accessed.
Specifically, the selecting to switch to the SUL carrier or the UL carrier in the first cell based on the first measurement result, the second measurement result and the first information includes:
switching to SUL carrier waves in the first cell under the condition that the first measurement result is higher than a first set threshold, the second measurement result is lower than a second set threshold and the first load is lower than a third set threshold;
Switching to UL carrier in the first cell when the first measurement result is lower than the first set threshold, the second measurement result is higher than the second set threshold, and the second load is lower than the third set threshold;
and performing round-robin switching between SUL carrier and UL carrier of the first cell under the condition that the first measurement result is higher than the first set threshold, the second measurement result is higher than the second set threshold, and the first load and the second load are both lower than the third set threshold.
Fig. 2 shows a schematic diagram of a terminal performing Time division multiplexing (TDM, time-Division Multiplexing) round-robin switching between a SUL carrier and an UL carrier, where four arrows in the diagram indicate switching occasions of switching between the SUL carrier and the UL carrier, where the round-robin switching performed by TDM may preferentially subtract the performance loss caused by the switching delay at 2.3 GHz.
In an embodiment, the method further comprises:
When the first terminal is in a connection state and is in an NR uplink time slot, under the condition that a 2.3GHz downlink carrier exists in the first cell, switching to an SUL carrier or an UL carrier is selected in the first cell accessed by the first terminal based on a third measurement result and first information; wherein,
The third measurement characterizes a measurement for the 2.3GHz downlink carrier; the first information characterizes at least one of a first load corresponding to a SUL carrier of the first cell or a second load corresponding to a UL carrier of the first cell.
In practical application, when the first cell has a 2.3GHz downlink carrier, a third measurement result about the 2.3GHz downlink carrier may be obtained based on an inter-frequency measurement manner, and in combination with the load condition of the SUL carrier or the UL carrier in the first cell, the second terminal is instructed to switch to the SUL carrier or the UL carrier through DCI. For example, when the result of the inter-frequency measurement is higher than the corresponding set threshold, the result of the same-frequency measurement is smaller than the corresponding set threshold, and the first load is lower than the third set threshold, the SUL carrier is switched in the first cell.
In an embodiment, when measuring the 2.3GHz downlink carrier, the method further comprises:
and setting a measurement interval about the 2.3GHz downlink carrier based on the SMTC information interacted with the first base station to which the first cell belongs.
Here, the first base station is required to interact SMTC information with the first terminal through the Xn interface on the basis of supporting time synchronization, and the first terminal configures a Measurement GAP (Measurement GAP) for the 2.3GHz downlink carrier based on the interacted SMTC information so that the Measurement GAP can encase the frequency domain location and the full period of the SSB.
In an embodiment, the method further comprises:
when the first terminal is in a connection state and is in an NR uplink time slot, selecting to switch to an SUL carrier or an UL carrier in a first cell accessed by the first terminal based on a set parameter; wherein,
The set parameters include all or part of the following parameters:
the speed or load of the uplink carrier wave in the set time;
Slice ID, 5QI, time delay requirement or reliability requirement corresponding to the service type of the terminal;
Carrier grid or radio frequency fingerprint.
In an embodiment, the method further comprises:
And when the first terminal is in a connection state and is in an NR downlink time slot, selecting to switch to the SUL carrier in a first cell accessed by the first terminal.
In the above embodiments, it is described how the first terminal in the connected state performs the selection of the uplink carrier under the same cell, and next, it is described how the first terminal in the connected state performs the selection of the uplink carrier when performing the same-frequency handover in different cells.

And receiving a first message issued by a first base station to which the first cell belongs under the condition that the first setting condition is met.
Wherein the first message indicates that the first terminal accesses a second cell; the second cell is a cell under a second base station.

In an embodiment, the first message is an RRC message.
Here, the first base station instructs the first terminal to complete the random access procedure on the SUL carrier or the UL carrier of the second base station by issuing the RRC handover reconfiguration message. The RRC handover reconfiguration message carries selection information related to the SUL carrier and the UL carrier of the second base station.
In an embodiment, the first setting condition includes:
the downlink measurement result of the second cell is lower than a fourth set threshold;
the load of the second cell is lower than a fifth set threshold; and
The second cell supports SUL carrier waves; wherein,
The second cell is a neighboring cell of the first terminal.
Here, the first terminal confirms whether the first setting condition is satisfied based on the information such as the downlink measurement result of the same-frequency neighboring cell, that is, the second cell, and the load interacting with the same-frequency neighboring cell. And when the downlink measurement result of the second cell is lower than a fourth set threshold and the load of the second cell is lower than a fifth set threshold, judging that the first terminal meets the first set condition. While the second cell needs to support the SUL carrier, it can be appreciated that in this scheme, the first terminal also supports the SUL carrier.
The embodiment of the application provides a method, a device, a terminal and a storage medium for selecting uplink carriers. When a terminal is in an idle state, selecting to access an SUL carrier or an UL carrier based on a first threshold, wherein the first threshold is determined based on at least one of a 5QI and a slice identifier corresponding to a service type of the first terminal; when the first terminal is in a connection state and in an NR uplink time slot, based on at least one of a measurement result of SUL carrier waves of the first cell, a measurement result of UL carrier waves of the first cell and a first load corresponding to SUL carrier waves of the first cell or a second load corresponding to UL carrier waves of the first cell, the SUL carrier waves or the UL carrier waves are selected to be switched to in the first cell accessed by the first terminal, and the uplink carrier waves selected in the mode can meet QoS requirements corresponding to service types, so that the matching performance of the uplink carrier waves and the service types is improved, and the uplink performance of a system is improved.
