Detailed Description
Before describing the uplink information transmission path determining method in the embodiment of the present invention in detail, first, an application architecture in the embodiment of the present invention is briefly described.
In the deployment process of a fifth generation mobile communication system (5G) network, a 5G cell can be used as a macro coverage independent network, and can also be used as a small station to perform coverage and capacity enhancement on an existing Long Term Evolution (LTE) network. No matter which networking mode is adopted, the dual connection technology can be used for realizing the interconnection of an LTE system and a 5G system, so that the wireless resource utilization rate of the whole mobile network system is improved, the time delay of system switching is reduced, and the performance of a user and the system is improved. The embodiment of the invention is suitable for a dual-connection application scene in which the terminal is connected with the main node and the auxiliary node, in particular to an EN-DC scene.
Taking an EN-DC scenario as an example, in EN-DC, a primary node is an Evolved node b (eNB) in an LTE system, a secondary node is a (gNB) in a 5G system, and a control plane is accessed to an Evolved Core network (EPC, Evolved Packet Core) through the eNB.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The embodiment of the invention provides a method for determining an uplink information transmission path. Fig. 1 is a flowchart illustrating a method for determining an uplink information transmission path according to an embodiment of the present invention; as shown in fig. 1, the method includes:
step 101: the terminal judges whether the triggering condition is satisfied.
Step 102: and when the condition that the triggering condition is met is judged, switching the transmission path of the uplink transmission information from a first link corresponding to the first node to a second link corresponding to the second node, and sending the uplink transmission information to the second node through the second link so that the second node forwards the uplink transmission information to the first node.
In an optional embodiment of the present invention, the determining, by the terminal, whether the trigger condition is satisfied includes: the terminal detects the self-capability parameter, the network quality parameter or the transmission attribute parameter and judges whether the self-capability parameter, the network quality parameter or the transmission attribute parameter meets the preset condition.
In this embodiment, the terminal determines whether to change the transmission path of the uplink transmission information according to the self capability parameter, the network quality parameter, or the transmission attribute parameter. Wherein the self capability parameter characterizes whether the terminal has the capability of transmitting uplink transmission information to the first node through the first link; the network quality parameter characterizes whether the network communication quality of the first node supports transmission of uplink transmission information; the transmission attribute parameter indicates the transmission condition currently transmitted through the first link, and may include, for example, a transmission duration, the number of transmission failures (or the number of retransmissions), and the like. The terminal may determine whether to change the transmission path of the uplink transmission information based on any of the above information or a combination of any of the information. It can be understood that the terminal decides to change the transmission path of the uplink transmission information, i.e., to switch the transmission path of the uplink transmission information from the first link corresponding to the first node to the second link corresponding to the second node, and to send the uplink transmission information to the second node through the second link, if the terminal itself has no capability to transmit the uplink transmission information to the first node through the first link, the network communication quality of the first node does not support the transmission of the uplink transmission information, or the transmission condition of the current transmission through the first link is not good.
In this embodiment, the first link may be a Physical Uplink Shared Channel (PUSCH) or a Physical Uplink Control Channel (PUCCH) corresponding to the first node; the second link may be a PUSCH and/or PUCCH corresponding to a second node; it can be understood that when the terminal determines that the trigger condition is satisfied, the terminal switches the data mapped to the PUSCH or PUCCH of the first node to be transmitted on the PUCCH and/or PUSCH mapped to the second node.
In this embodiment, the first node and the second node may be an LTE base station and an NR base station, respectively, or an NR base station and an LTE base station, or both an LTE base station and an NR base station.
The uplink transmission information is at least part of information to be sent to the first node by the terminal, and may be all information to be sent or part of information to be sent. As an embodiment, the uplink transmission information is at least one of the following information: radio Resource Control (RRC) signaling, random Access signaling, Media Access Control Element (MAC CE), and physical layer parameters; wherein the physical layer parameters include at least one of: channel state information-Reference Signal (CSI-RS) Resource indication CRI (CSI-RS Resource Indicator), Channel Quality Indication (CQI), Precoding Matrix Indication (PMI), Reference Signal Received Power (RSRP), acknowledgement/negative response (ACK/NACK), and the like.
As a first implementation manner, the determining whether the self capability parameter, the network quality parameter, or the transmission attribute parameter satisfies a preset threshold includes: the terminal judges whether the type of the uplink transmission information is a preset information type; the judgment that the preset trigger condition is met comprises the following steps: and when the type of the uplink transmission information is a preset information type, judging that the triggering condition is met.
In this embodiment, the type of the uplink transmission information indicates a scene or a flow corresponding to current information transmission. As an example, the scenario or procedure is, for example, a random access procedure, and the uplink transmission information may be uplink information in the random access procedure. The terminal may predetermine a preset information type, and when the type of the uplink transmission information is the preset information type, determine that the trigger condition is satisfied, switch a transmission path of the uplink transmission information from a first link corresponding to the first node to a second link corresponding to the second node, and send the uplink transmission information to the second node through the second link.
For example, after the UE is connected to the LTE base station, the UE needs to be connected to the NR base station to form a dual connection, and when a random access (for example, contention-based random access) process is initiated to the NR base station, the UE determines to forward a second uplink message of the random access through the LTE base station, so that when uplink transmission information is transmitted, the uplink transmission information that is mapped to the PUSCH channel corresponding to the NR base station is mapped to the PUSCH corresponding to the LTE base station and is marked, and the LTE forwards the uplink transmission information to the NR base station after receiving the uplink transmission information, thereby completing a subsequent random access process.
In other embodiments, for other uplink information after the random access is successful, the UE may determine whether to maintain the original transmission path or change the transmission path according to the following determination method.
As a second implementation manner, the determining whether the self capability parameter, the network quality parameter, or the transmission attribute parameter satisfies a preset threshold includes: the terminal measures the network quality parameter of the first node and judges whether the network quality parameter of the first node is lower than a first preset threshold value or not; the judgment that the preset trigger condition is met comprises the following steps: and when the network quality parameter of the first node is lower than a first preset threshold value, judging that a triggering condition is met.
In this embodiment, the network quality parameter includes, but is not limited to, at least one of the following: RSRP, Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indication (RSSI), Signal to Interference plus Noise Ratio (SINR), and so forth. The terminal may determine a first preset threshold in advance, determine that a trigger condition is satisfied when a network quality parameter of the first node is lower than the first preset threshold, switch a transmission path of uplink transmission information from a first link corresponding to the first node to a second link corresponding to a second node, and send the uplink transmission information to the second node through the second link.
For example, the UE is in EN-DC state, the LTE base station is the primary base station, and the NR base station is the secondary base station. When the UE needs to perform uplink transmission information transmission, it is assumed that the UE needs to send uplink transmission information to the NR base station, the UE first performs RSRP measurement on the NR base station, compares the measurement result with an RSRP threshold (i.e., a first preset threshold), and when the measurement result is lower than the RSRP threshold (i.e., the first preset threshold), determines to perform switching of an uplink transmission information transmission path, i.e., sends the uplink transmission information to the LTE base station, and then forwards the uplink transmission information to the NR base station by the LTE base station.
As a third implementation manner, the determining whether the self capability parameter, the network quality parameter, or the transmission attribute parameter satisfies a preset threshold includes: the terminal detects the failure times or retransmission times of the uplink transmission information transmitted through the first link and judges whether the failure times or retransmission times exceed a second preset threshold value; the judgment that the preset trigger condition is met comprises the following steps: and when the failure times or the retransmission times exceed a second preset threshold value, judging that a triggering condition is met.
In this embodiment, the terminal may determine a second preset threshold in advance, determine that a trigger condition is satisfied when the number of failures or the number of retransmissions of the uplink transmission information transmitted through the first link exceeds the second preset threshold, switch a transmission path of the uplink transmission information from a first link corresponding to the first node to a second link corresponding to the second node, and send the uplink transmission information to the second node through the second link. In practical application, the terminal can be provided with a counter; and when the sending of the uplink transmission information fails once or the retransmission of the uplink transmission information is once, the counting of the counter is increased by one until the counting value of the counter reaches the second preset threshold value, and the triggering condition is judged to be met.
For example, the UE is in EN-DC state, the LTE base station is the primary base station, and the NR base station is the secondary base station. The UE needs to send uplink transmission information to the secondary base station, after the sending fails, the UE performs statistics on the number of failures, and when the UE fails N times (N is a second preset threshold), the UE determines to perform switching of a transmission path of the uplink transmission information, that is, sends the uplink transmission information to the LTE base station, and then forwards the uplink transmission information to the NR base station.
As a fourth implementation manner, the determining whether the self capability parameter, the network quality parameter, or the transmission attribute parameter satisfies a preset threshold includes: the terminal detects the transmission time length for transmitting the uplink transmission information through the first link and judges whether the transmission time length exceeds a third preset threshold value; the judgment that the preset trigger condition is met comprises the following steps: and when the transmission time exceeds a third preset threshold value, judging that a triggering condition is met.
In this embodiment, the terminal may determine a third preset threshold in advance, determine that a trigger condition is satisfied when a transmission duration for transmitting the uplink transmission information through the first link exceeds the third preset threshold, switch a transmission path of the uplink transmission information from the first link corresponding to the first node to a second link corresponding to the second node, and send the uplink transmission information to the second node through the second link. In practical application, the terminal may set a timer, and start the timer when the uplink transmission information starts to be transmitted through the first link for the first time, where the timing duration of the timer is the third preset threshold; if the timer is overtime, the uplink transmission information is still not successfully transmitted through the first link, and the triggering condition is determined to be met.
For example, the UE is in EN-DC state, the LTE base station is the primary base station, and the NR base station is the secondary base station. The UE sends uplink transmission information to the secondary base station and starts a timer, wherein the timing duration of the timer is the third preset threshold; if the timer is overtime, the UE determines to switch the transmission path of the uplink transmission information, that is, the UE sends the uplink transmission information to the LTE base station, and then the LTE base station forwards the uplink transmission information to the NR base station.
As a fifth implementation manner, the determining whether the self capability parameter, the network quality parameter, or the transmission attribute parameter satisfies a preset threshold includes: the terminal detects a PH parameter and judges whether the PH parameter is lower than a fourth preset threshold value; the judgment that the preset trigger condition is met comprises the following steps: and when the PH parameter is lower than a fourth preset threshold value, judging that a triggering condition is met.
In this embodiment, the terminal may determine a fourth preset threshold in advance, determine that the trigger condition is satisfied when the terminal detects that the PH parameter of the terminal is lower than the fourth preset threshold, switch a transmission path of uplink transmission information from a first link corresponding to the first node to a second link corresponding to the second node, and send the uplink transmission information to the second node through the second link.
In an optional embodiment of the invention, the method further comprises: the terminal obtains the preset condition configured by the network equipment; or, the terminal determines the preset condition through a protocol agreed mode.
In this embodiment, as an implementation manner, at least one of the preset information type, the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold may be configured by a network device, for example, the network device notifies the terminal through broadcast information. As another embodiment, at least one of the preset information type, the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold may be written in advance into the terminal by the terminal according to a protocol convention.
In an optional embodiment of the present invention, if the terminal determines the first preset condition in advance according to a protocol-agreed manner, and then obtains a second preset condition configured by the network device, the preset condition is updated to the second preset condition, for example, the terminal determines a first preset threshold 1 in the protocol-agreed manner, and obtains a first preset threshold 2 configured by the network device, then the terminal stores the first preset threshold 2, and determines whether to switch the transmission path according to the first preset threshold 2.
In other embodiments, the terminal obtains the preset condition configured by the network device, and may further include information such as an effective duration of the preset condition, and the terminal determines whether to switch the transmission path according to the preset condition configured by the network device and the corresponding effective duration. For example, the terminal determines a first preset threshold 1 by a protocol convention mode, obtains a first preset threshold 2 configured by the network device, and if the effective duration of the first preset threshold 2 is t, the terminal stores the first preset threshold 2, judges whether to switch the transmission path according to the first preset threshold 2, and starts a timer, and the timing duration of the timer is set to t; before the timer is overtime, the terminal judges whether to switch the transmission path according to a first preset threshold 2; after the timer is overtime, the terminal judges whether to switch the transmission path according to a first preset threshold value 1.
In an alternative embodiment of the present invention, the terminal needs to perform a determination of whether to switch the transmission path every time the terminal transmits the uplink transmission information, that is, perform the determination of step 101 to step 102. In other embodiments, the terminal may perform the determination only once in the preset period based on a predetermined agreement or configuration of the network device, that is, perform the determination of steps 101 to 102 only once in the preset period; if the path switching is judged, switching the transmission path of the uplink transmission information from a first link corresponding to the first node to a second link corresponding to the second node in the preset period; if the path is not switched, the uplink transmission information is still transmitted to the first node from the first link corresponding to the first node within the preset period.
In an optional embodiment of the present invention, in the process of sending the uplink transmission information to the second node through the second link, the uplink transmission information is still sent through the first link, that is, uplink diversity sending is performed, and both the primary link and the secondary link send. In practical applications, a Time Division Duplex (TDD) mode may be adopted.
By adopting the technical scheme of the embodiment of the invention, the switching of the uplink transmission path is realized when the triggering condition is met by the terminal through judging whether the terminal meets the triggering condition, the uplink transmission information transmitted through the first link is switched to the second link for transmission, and then the uplink transmission information can be forwarded to the first node through the second node, so that the condition that the uplink information cannot be transmitted due to the limited channel coverage of the base station is avoided, the problems of addition failure of an auxiliary node, transmission failure after the establishment of subsequent connection and the like are also avoided, and the user experience is also improved.
