Background

Currently, MRDC networks begin to focus on NRDC, where the primary station MN is usually in the FR1 band and the secondary station SN is in the FR2 band, so that low or medium frequency can be used for coverage, and adding high frequency can improve throughput in hot spot areas.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present application based on the embodiments herein.

It should be noted that the following is a simple description of the background of the present solution:

the scheme mainly surrounds the carrier which is accessed to the SN based on normal four-step random access in the prior art. However, the UE and the base station consider energy saving and dynamically adjust whether to access the SN network according to the traffic. In this case, multiple times of access and release of SN occur in the connection state of the UE and the MN, the access delay is enlarged, the SN carrier cannot be immediately used for transmission like CA, and the random access is restarted due to the access failure, so that the technical problem of efficiency to be optimized is developed. It will be appreciated that MRDC networks now begin to focus on NRDC, with primary station MN typically being in FR1 and secondary station SN being in FR2, so that either low or medium frequency can be used for coverage, and the addition of high frequency can improve throughput in hot spot areas. Since this is inter-station NRDC, the way for the UE to add another SN wirelessly is downlink synchronization plus uplink synchronization (also random access). The downlink synchronization is achieved by directly desynchronizing the frequency point of the SN cell given by the MN without searching the network, but in the prior art, the UE also needs to do random access to be in uplink synchronization with the SCG (secondary cell). In the prior art, the carrier of the SN is accessed based on normal four-step random access, in this case, multiple times of access and release of the SN can occur under the connection state of the UE and the MN (namely, the access time delay is enlarged, the carrier of the SN cannot be used for transmission immediately like a CA, the random access can be restarted due to access failure, and the efficiency is required to be optimized.

In order to solve the technical problems, embodiments of the present application provide a data transmission method based on an NRDC network. The data transmission method based on the NRDC network is mainly applied to the 5G auxiliary station SN of the Haomi wave frequency band, and by utilizing uplink channel data sent by the target terminal equipment UE and analyzing SRS carried in the uplink channel data when the carrier wave of the SN is accessed, the auxiliary station can determine a time delay TA value according to the SRS after receiving the SRS and transmit the time delay TA value to the UE through downlink channel data transmission, so that the target terminal equipment UE can calibrate the reference time according to the time delay TA value. The access efficiency of the NRDC in the case of SN multiple access release on the premise of energy saving and throughput is optimized. The data transmission can be started after the original four-step random access is finished, and the UE can be synchronized with the base station and can transmit the data simultaneously by optimizing the data transmission.

Referring to fig. 1, fig. 1 is a flow chart of a data transmission method based on an NRDC network according to an embodiment of the present application. The data transmission method based on the NRDC network is applied to terminal equipment. Optionally, the terminal device is a terminal or a server. Optionally, the server is an independent physical server, or a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs (Content Delivery Network, content delivery networks), basic cloud computing services such as big data and artificial intelligence platforms, and the like. Optionally, the terminal is a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, a smart voice interaction device, a smart home appliance, a vehicle-mounted terminal, and the like, but is not limited thereto.

The following is an explanation of the terms appearing herein:

NRDC (New Radio-Dual Connectivity) network, i.e. NR dual connectivity network, in NRDC model, master RAN and second RAN nodes are both 5G gNB (New Radio NodeB), and terminal equipment UE may be connected to one gNB serving as a primary node and one gNB serving as a Secondary node at the same time; wherein the Master Node is connected to a 5GC (5G core network), and the auxiliary Node second Node is connected to the Master Node through an Xn interface.

PUSCH (Physical Uplink Shared Channel) is a physical uplink shared channel for carrying data from the transport channel USCH.

PDSCH (Physical Downlink Shared Channel), physical downlink shared channel, is used to carry data from the transport channel DSCH.

SRS (Sounding Resource Signal), namely detecting a resource signal, is used for estimating the frequency domain information of an uplink channel in wireless communication, and performs frequency selective scheduling; the method is used for estimating the downlink channel and performing downlink beam shaping.

TA (time advanced), i.e. the maximum time advance, refers to the difference between the actual time the mobile station signal arrives at the base station and the time the mobile station signal arrives at the base station assuming that the mobile station is 0 from the base station.

In an embodiment, the method may comprise the steps of:

step 101, uplink channel PUSCH data carrying a sounding resource signal SRS sent by a target terminal device UE is received.

It should be noted that the scheme is mainly suitable for the secondary station SN with small coverage area to access to a scene, such as the 5G secondary station SN with the hao wave frequency band. Since NRDC is generally composed of FR1 band and FR2 band. FR1 is used as MN site, broad coverage is applied, FR2 is used as SN site, and the speed problem is solved. The cell has a cyclic prefix in the signal frame reached by the uplink of the UE, the time when the UE arrives at the base station can be within the cyclic prefix, and the UE under the base station has a distance from the base station, but can be received by the base station as long as the UE falls within the cyclic prefix. And FR2 is high frequency, 5G auxiliary station SN of the hao wave frequency band covers itself very little, namely UE and distance between 5G auxiliary station SN of the hao wave frequency band is small, cyclic prefix is very short, the base station can receive the uplink channel PUSCH data that UE sent directly.

By utilizing the characteristics, the scheme utilizes configuration scheduling to send the PUSCH and carry the SRS when the carrier of the SN is accessed, and the auxiliary station SN can determine the time delay TA value according to the SRS after receiving the SRS. Other base stations with large distances from the UE, which are different from the 5G auxiliary station SN of the Hami wave frequency band, are accessed by adopting a conventional four-step random access method to determine a time delay TA value, so that the access efficiency of the auxiliary station SN is greatly improved.

Step 102, parsing the uplink channel PUSCH data.

In this embodiment, the secondary station SN needs to analyze the uplink channel PUSCH data first after receiving it, and determines that the sounding resource signal SRS can be obtained.

Step 103, if the sounding reference signal SRS can be obtained by analyzing the uplink PUSCH data, calculating a time delay TA value of the target terminal device UE relative to the secondary station SN according to the sounding reference signal SRS.

In the process of analyzing the PUSCH data of the uplink channel, the secondary station SN may fail to analyze, and the sounding resource signal SRS may be obtained by analyzing the PUSCH data of the uplink channel, so as to calculate the time delay TA value of the target terminal device UE relative to the secondary station SN according to the sounding resource signal SRS.

If the sounding resource signal SRS can not be obtained by analyzing the uplink channel PUSCH data, generating prompt information, writing the prompt information into the downlink channel PDSCH data and sending the prompt information to the target terminal equipment UE so as to prompt the target terminal equipment UE to send the uplink channel PUSCH data to the auxiliary station SN again, and the data transmission is not affected. And the random access is required to be restarted by the normal random access failure.

It should be noted that, calculating the time delay TA value by using the sounding resource signal SRS is a conventional technical means, and will not be described herein.

Step 104, writing the time delay TA value into downlink PDSCH data and sending the data to the target UE, so that the target UE calibrates the reference time according to the time delay TA value.

The time delay TA value of the target terminal equipment UE relative to the auxiliary station SN is obtained through calculation, so that the terminal equipment UE can automatically calibrate the reference time according to the time delay TA value, and the purpose of indirectly eliminating the time delay is achieved.

In some embodiments, since there is more than one terminal device UE to access the secondary station SN in practice, the secondary station SN needs to accurately send the delay TA value to the corresponding terminal device UE after calculating the delay TA value. It is therefore necessary to determine the identity of the terminal device to receive the delay TA value.

Obtaining terminal equipment parameters for determining the terminal equipment identification by analyzing the uplink channel PUSCH data; calculating to obtain a terminal equipment identifier based on a preset identifier determining algorithm and terminal equipment parameters; and determining target terminal equipment (UE) of the TA value to be received according to the terminal equipment identifier.

The identification determination algorithm comprises:

C-RNTI＝1+Frame_id+14×slot_id+14×80×frequency_id+14×80×8×PCImn

In some embodiments, since the control plane of NRDC is on the MN side, the control signaling is sent from the radio resource configuration (RRCConfig) signaling on the master station MN side, and therefore before receiving the uplink PUSCH data carrying the sounding resource signal SRS sent by the target terminal device UE, the method further includes the following steps:

and sending a wireless resource configuration signaling to the target terminal equipment UE through the master station MN so as to set the size of uplink channel PUSCH data sent by the target terminal equipment UE to the auxiliary station SM, wherein the wireless resource configuration signaling comprises frequency domain resources and time domain resources for configuration and scheduling.

In some embodiments, after parsing the uplink channel PUSCH data, the method further includes the steps of:

and obtaining a status report for representing the current data quantity to be transmitted of the target terminal equipment UE by analyzing the uplink channel PUSCH data, so that the base station SN can allocate resources for the target terminal equipment UE according to the status report when dynamically scheduling uplink transmission data. And if no uplink data needs to be transmitted currently, filling.

Any combination of the above optional solutions may be adopted to form an optional embodiment of the present application, which is not described herein in detail.

In particular, the present application is not limited by the order of execution of the steps described, and certain steps may be performed in other orders or concurrently without conflict.

As can be seen from the above, the NRDC network-based data transmission method provided in the embodiments of the present application receives PUSCH data of an uplink channel carrying a sounding resource signal SRS sent by a target terminal device UE; analyzing the uplink channel PUSCH data; if the sounding resource signal SRS can be obtained by analyzing the uplink channel PUSCH data, calculating a time delay TA value of the target terminal equipment UE relative to the auxiliary station SN according to the sounding resource signal SRS; and writing the time delay TA value into downlink channel PDSCH data and sending the data to the target terminal equipment UE so that the target terminal equipment UE can calibrate the reference time according to the time delay TA value. By using the NRDC network-based data transmission method provided by the embodiment of the present application, by using uplink channel data sent by the target terminal device UE and analyzing the SRS carried in the uplink channel data when the carrier of the SN is accessed, the secondary station can determine the delay TA value according to the SRS after receiving the SRS and transmit the delay TA value to the UE through downlink channel data transmission, so that the target terminal device UE calibrates the reference time according to the delay TA value. The access efficiency of the NRDC in the case of SN multiple access release on the premise of energy saving and throughput is optimized. The data transmission can be started after the original four-step random access is finished, and the UE can be synchronized with the base station and can transmit the data simultaneously by optimizing the data transmission.
