Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an uplink signaling transmission method and apparatus, a computer-readable storage medium, and a terminal.
Background
Currently, a dual connectivity technology is introduced in a Long Term Evolution (LTE) system. As shown in fig. 1, in such a scenario applying the dual connectivity technology, a User Equipment (UE, also referred to as a terminal) can simultaneously use resources of two LTE base stations to perform data transmission, which not only can improve data throughput, but also can improve mobility. For a UE configured with dual connectivity, a Master base station (Master eNB, MeNB) connected to the UE is responsible for transmission of Radio Resource Control (RRC) signaling, and a Secondary base station (Secondary eNB, SeNB) is responsible for configuration of a Secondary Cell Group (SCG). The secondary base station only transmits data, and the SCG cell configured by the secondary base station needs to be sent to the UE through the main base station by RRC signaling. The primary base station and the secondary base station may each configure a plurality of serving cells to the UE. A Primary Cell (PCell) is configured on a Primary base station side, a physical uplink control channel is configured in the Primary Cell, and the UE receives a system message and a paging message from the Primary Cell. A Primary Secondary Cell (PSCell), which may also be referred to as a Primary Secondary Cell, is configured on the Secondary base station side, and a physical uplink control channel is also configured in the Secondary Cell. Other cells serving the UE are called slave cells.
With the development of wireless technology, 3GPP will introduce New wireless technology (NR), which can also be referred to as a fifth Generation mobile communication technology (5th-Generation,5G), to meet the demand of larger data volume and the demand of smaller transmission delay. Operators have widely deployed LTE networks, so in order to fully utilize existing LTE networks, NR cannot be deployed independently in the early stage of NR deployment, and needs to cooperate closely with LTE networks (light Interworking), and LTE and NR dual connectivity techniques may be used so that UEs can use LTE and NR for data transmission at the same time. In LTE-NR dual connectivity, there are packet Signaling Radio bearers (Split Signaling Radio Bearer, Split SRB) and secondary cell group Signaling Radio bearers (SCG SRB). As shown in fig. 2, SRBs (i.e., SCG SRBs) may also be configured on the secondary base station side, so that the UE and the SeNB may directly perform RRC signaling interaction. For a downlink scene of the Split SRB, an RRC entity is positioned at a main base station and sends a signaling to a Packet Data Convergence Protocol (PDCP) entity for processing; the PDCP entity may be followed by two transmission paths: the PDCP entity can deliver RRC signaling to a Radio Link Control (RLC) entity RLC at the primary base station sideLTEThe RRC signaling may also be handed over to the RLC entity RLC of the secondary base station side via the X2 interface between the primary and secondary base stations (the interface between the primary and secondary base stations may take other names)NRProcessing; after the RLC entity finishes processing, relevant data is sentThe packet (the packet is a signaling packet, and an RRC signaling can be segmented into several segments by RLC) is delivered to a Medium Access Control (MAC) entity MACLTEOr MACNRAnd (6) processing. And then transmits the signaling to the UE through the physical layer. Generally, the UE needs to perform measurement according to measurement parameters configured by the primary base station, and send a measurement report to the network side when a reporting condition is met.
However, when the UE configures LTE-NR dual connectivity, the transmission path of uplink RRC signaling is still determined according to RRC signaling configuration; when the channel deteriorates, poor communication quality is caused.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 3 is a flowchart of an uplink signaling transmission method according to an embodiment of the present invention.
The uplink signaling transmission method shown in fig. 3 may be used in the user equipment side. The uplink signaling transmission method may include the steps of:
step S301: when an uplink signaling needs to be sent, determining the transmission path quality of a main cell signal and the transmission path quality of an auxiliary cell signal;
step S302: determining a transmission mode of the uplink signaling according to the transmission path quality of the primary cell signal and/or the transmission path quality of the secondary cell signal, wherein the transmission mode is selected from the following transmission modes: and sending the uplink signaling through a bearer at the side of the main base station, sending the uplink signaling through a bearer at the side of the auxiliary base station, and repeatedly sending the uplink signaling, wherein the repeatedly sending of the uplink signaling refers to sending the same uplink signaling through the bearer at the side of the main base station and the bearer at the side of the auxiliary base station.
The primary base station in this embodiment may be an LTE base station, and the secondary base station is an NR base station; or, the primary base station may be an NR base station, and the secondary base station is an LTE base station. Further, the primary cell may be a cell served by the primary base station for the UE, from which the UE receives a system message and a paging message, and on which the UE is configured with a physical uplink control channel. It should be noted that the master base station may not only provide the master cell, but also have other cells serving the UE, and these cells are referred to as slave cells. The secondary cell may be a cell served by the secondary base station for the UE, the UE is configured with a physical uplink control channel on the cell, and the secondary base station may also have other cells serving the UE, which are referred to as secondary cells.
It should be understood by those skilled in the art that the primary cell, the secondary cell, and the secondary cell may also adopt any other practicable names, and the embodiment of the present invention is not limited thereto.
In a specific implementation, in step S301, the user equipment may determine the transmission path quality of the primary cell signal and the transmission path quality of the secondary cell signal. Specifically, the transmission path quality of the primary cell signal may characterize the degree to which the primary cell signal is accurately received, and the transmission path quality of the secondary cell signal may characterize the degree to which the secondary cell signal is accurately received.
Further, the transmission path quality may be a signal quality or a path loss of a signal. Further, the signal quality may be expressed using at least one of the following parameters: reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ). The path loss of the signal may represent a difference between a transmission power of the base station side reference signal and a reception power of the user equipment.
It is to be understood that the signal quality may also be expressed in terms of at least one of the following parameters: received Signal Strength Indicator (RSSI), Signal to Interference plus Noise Ratio (SINR).
In a specific implementation, in step S302, the transmission mode of the uplink signaling may be determined only according to the transmission path quality of the primary cell signal, only according to the transmission path quality of the secondary cell signal, or according to the transmission path quality of the primary cell signal and the transmission path quality of the secondary cell signal. That is, the optimal transmission path may be determined by the transmission path quality of the primary cell signal and/or the specific value of the transmission path quality of the secondary cell signal; transmitting the uplink signaling through the optimal transmission path, and ensuring that the uplink signaling is received by the base station to the maximum extent; in addition, the step S302 can also make the transmission of the uplink signaling adapt to the change of the channel quality, and especially ensure the accurate transmission and reception of the uplink signaling in case that the uplink signaling transmission channel configured by the base station deteriorates.
Further, the transmission mode may be selected from: and sending the uplink signaling through a bearer at the side of the main base station, sending the uplink signaling through a bearer at the side of the auxiliary base station, and repeatedly sending the uplink signaling, wherein the repeatedly sending of the uplink signaling refers to sending the same uplink signaling through the bearer at the side of the main base station and the bearer at the side of the auxiliary base station. That is, one of the three transmission modes may be selected according to the specific situation of the transmission path quality of the primary cell signal and/or the transmission path quality of the secondary cell signal. The diversification of the transmission mode can also ensure the transmission of uplink signaling.
It can be understood that the uplink signaling may be a Radio Resource Control (RRC) signaling or any other implementable signaling, which is not limited in this embodiment of the present invention. The Bearer may be a Bearer dedicated to transmitting Signaling, and may be, for example, a Signaling Radio Bearer (SRB). Further, the transmission path may be the bearer, and the transmission path quality may characterize the transmission quality of the bearer.
In a specific application scenario of the present invention, referring to fig. 2, an LTE base station in fig. 2 is a master base station, and a signaling radio bearer may include an RRC entity, a PDCP entity, an RLC entity, and an MAC entity, and a physical layer not shown. After receiving RRC signaling (including measurement report) sent by the RRC entity, the PDCP entity at the UE side may sequentially pass the RRC signaling through the RLC entity at the LTE sideLTE/MAC entity MACLTEThe physical layer processing is sent to an LTE base station through an air interface of an LTE side, namely through a main baseA bearing at a station side sends an uplink signaling; it can also pass through the RLC entity RLC of the NR sideNR/MAC entity MACNRAnd the physical layer processing is sent to the NR base station through an air interface at the NR side, namely, the uplink signaling is sent through a bearer at the auxiliary base station side. If the main base station is an LTE base station, the NR base station sends the PDCP entity PDCP of the main base station side through an X2 interface with the main base stationLTEPDCP entityLTEAnd after the processing, the main base station side RRC entity carries out processing.
Preferably, step S302 may include the steps of: if the transmission path quality of the main cell signal is superior to a first quality threshold, sending the uplink signaling through a bearer on a main base station side, otherwise, repeatedly sending the uplink signaling, wherein the fact that the transmission path quality of the main cell signal is superior to the first quality threshold means that: the signal quality of the main cell signal is higher than or equal to a first signal threshold, or the path loss of the main cell signal is lower than or equal to a first path loss threshold.
Since the transmission of the uplink and downlink data or signaling is mainly transmitted through the primary cell, only the transmission path quality of the primary cell signal is determined in this embodiment. When the quality of the transmission path of the main cell signal is superior to the first quality threshold, the quality of the transmission path of the main cell signal is superior, and the transmission accuracy of the uplink signaling can be ensured by sending the uplink signaling through the load of the main base station side. Otherwise, if the transmission path quality of the main cell signal is not better than the first quality threshold, that is, the signal quality of the main cell signal is lower than or equal to the first signal threshold, or the path loss of the main cell signal is higher than or equal to the first path loss threshold, indicating that the transmission path quality of the main cell signal is poor, sending the uplink signaling through the bearer at the main base station side cannot ensure the transmission accuracy of the uplink signaling, and at this time, repeatedly sending the uplink signaling; in this case, the accuracy of uplink signaling transmission can be ensured by sending the same uplink signaling through the bearer on the primary base station side and the bearer on the secondary base station side.
Preferably, step S302 may include the steps of: if the transmission path quality of the secondary cell signal is superior to a second quality threshold, sending the uplink signaling through a bearer on a secondary base station side, otherwise, repeatedly sending the uplink signaling, wherein the fact that the transmission path quality of the secondary cell signal is superior to the second quality threshold means that: and the signal quality of the auxiliary cell signal is higher than or equal to a second signal threshold, or the path loss of the auxiliary cell signal is lower than or equal to a second path loss threshold.
In this embodiment, only the transmission path quality of the secondary cell signal may be determined. When the transmission path quality of the auxiliary cell signal is better than the second quality threshold, it indicates that the transmission path quality of the auxiliary cell signal is better, and the uplink signaling is sent through the bearer at the auxiliary base station side, so that the transmission accuracy of the uplink signaling can be ensured. Otherwise, if the transmission path quality of the secondary cell signal is not better than a second quality threshold, that is, the signal quality of the secondary cell signal is lower than or equal to the second signal threshold, or the path loss of the secondary cell signal is higher than or equal to the second path loss threshold, indicating that the transmission path quality of the secondary cell signal is poor, sending the uplink signaling through the bearer at the secondary base station side cannot ensure the transmission accuracy of the uplink signaling, and at this time, repeatedly sending the uplink signaling; in this case, the accuracy of uplink signaling transmission can be ensured by sending the same uplink signaling through the bearer on the primary base station side and the bearer on the secondary base station side.
It should be noted that specific values of the first signal threshold, the first path loss threshold, the second signal threshold, and the second path loss threshold may be configured and adjusted according to an actual application environment, which is not limited in this embodiment of the present invention.
Preferably, step S302 may include the steps of: if the transmission path quality of the primary cell signal is better than a first quality threshold, the uplink signaling is sent through a bearer on the primary base station side, wherein the better transmission path quality of the primary cell signal than the first quality threshold means: the signal quality of the main cell signal is higher than or equal to a first signal threshold, or the path loss of the main cell signal is lower than or equal to a first path loss threshold; determining a first comparison result of the transmission path quality of the secondary cell signal with a second quality threshold if the transmission path quality of the primary cell signal is not better than the first quality threshold; if the first comparison result shows that the transmission path quality of the secondary cell signal is better than the second quality threshold, the uplink signaling is sent through the bearer on the secondary base station side, otherwise, the uplink signaling is sent repeatedly, wherein the fact that the transmission path quality of the secondary cell signal is better than the second quality threshold means that: and the signal quality of the auxiliary cell signal is higher than or equal to a second signal threshold, or the path loss of the auxiliary cell signal is lower than or equal to a second path loss threshold.
In this embodiment, the transmission path quality of the primary cell signal is preferentially determined. And when the transmission path of the main cell signal is better, the uplink signaling is sent through the load of the main base station side. If the transmission path quality of the primary cell signal is poor, the transmission path quality of the secondary cell signal can be judged through the first comparison result; when the transmission path of the auxiliary cell signal is better, the uplink signaling is sent through the bearing of the auxiliary base station side; otherwise, if the transmission path quality of the main cell signal and the transmission path quality of the auxiliary cell signal are poor, the uplink signaling is repeatedly sent to ensure the accurate receiving of the transmission signaling.
Preferably, step S302 may include the steps of: if the transmission path quality of the secondary cell signal is better than a second quality threshold, the uplink signaling is sent through a bearer on the secondary base station side, wherein the transmission path quality of the secondary cell signal is better than the second quality threshold means: the signal quality of the auxiliary cell signal is higher than or equal to a second signal threshold, or the path loss of the auxiliary cell signal is lower than or equal to a second path loss threshold; determining a second comparison of the transmission path quality of the primary cell signal to the first quality threshold if the transmission path quality of the secondary cell signal is not better (i.e., worse) than the second quality threshold; if the second comparison result shows that the transmission path quality of the main cell signal is superior to the first quality threshold, the uplink signaling is sent through the bearer on the main base station side, otherwise, the uplink signaling is sent repeatedly, wherein the fact that the transmission path quality of the main cell signal is superior to the first quality threshold means that: the signal quality of the main cell signal is higher than or equal to a first signal threshold, or the path loss of the main cell signal is lower than or equal to a first path loss threshold.
In this embodiment, the transmission path quality of the secondary cell signal is preferentially determined. And when the transmission path of the auxiliary cell signal is better, the uplink signaling is sent through the bearing of the auxiliary base station side. If the transmission path quality of the secondary cell signal is poor, the transmission path quality of the primary cell signal can be judged through a second comparison result; when the transmission path of the main cell signal is better, the uplink signaling can be sent through the load of the main base station side; otherwise, if the transmission path quality of the main cell signal and the transmission path quality of the auxiliary cell signal are poor, the uplink signaling is repeatedly sent to ensure the accurate receiving of the transmission signaling.
As shown in fig. 4, fig. 4 is a flowchart of a specific implementation step of step S302 shown in fig. 3.
In this embodiment, the transmission path quality of the cell signal and the transmission path quality of the secondary cell signal are determined at the same time. In step S401, it is determined whether the transmission path quality of the primary cell signal is better than a first quality threshold, and whether the transmission path quality of the secondary cell signal is better than a second quality threshold.
After the step S401, the determination result and the subsequent operation include four cases, case 1(case1), case 2(case2), case 3(case3), and case 4(case 4).

In step S402, the determination result is that the transmission path quality of the primary cell signal is better than the first quality threshold, and the transmission path quality of the secondary cell signal is better than the second quality threshold. In step S403, it is determined whether or not the transmission path quality of the primary cell signal is better than the transmission path quality of the secondary cell signal. If yes, step S404 is carried out, and the uplink signaling is sent through the load bearing of the main base station side; otherwise, step S405 is performed, and the uplink signaling is sent through the bearer on the secondary base station side. Wherein, the quality of the transmission path of the primary cell signal being better than the first quality threshold means: the signal quality of the main cell signal is higher than or equal to a first signal threshold, or the path loss of the main cell signal is lower than or equal to a first path loss threshold, and the quality of the transmission path of the auxiliary cell signal is better than a second quality threshold means: and the signal quality of the auxiliary cell signal is higher than or equal to a second signal threshold, or the path loss of the auxiliary cell signal is lower than or equal to a second path loss threshold.
Case2 may include step S406 and step S404. In step S406, the determination result indicates that the transmission path quality of the primary cell signal is better than the first quality threshold, and the transmission path quality of the secondary cell signal is not better than the second quality threshold. If the transmission path of the primary cell signal is better, the process proceeds to step S404, and the uplink signaling is sent through the bearer on the primary base station side.
Case3 may include step S407 and step S405. In step S407, the determination result is that the transmission path quality of the secondary cell signal is better than the second quality threshold, and the transmission path quality of the primary cell signal is not better than the first quality threshold. If the transmission path of the secondary cell signal is better, the process proceeds to step S405, and the uplink signaling is sent through the bearer on the secondary base station side.
Case4 may include step S408 and step S409. In step S408, the determination result indicates that the transmission path quality of the secondary cell signal is not better than the second quality threshold, and the transmission path quality of the primary cell signal is not better than the first quality threshold. At this time, it indicates that the transmission path of the secondary cell signal and the transmission path of the primary cell signal are both poor, step S409 is entered, and the uplink signaling is repeatedly sent.
