Obviously, the described embodiments are part of the embodiments of the present application, but not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this application belong to the protection scope of this application.

It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein and that "first" and "second" distinguish objects.

In addition, "and" in the specification and claims indicates at least one of the connected objects, and the character "/" generally indicates that the related objects are an "or" relationship.

It is worth pointing out that the technology described in the embodiment of this application is not limited to the Long Term Evolution (Long Term Evolution, LTE)/LTE-Advanced (LTE-Advanced, LTE-A) system, and can also be used in other wireless communication systems, such as code division Multiple Access (Code Division Multiple Access, CDMA), Time Division Multiple Access (Time Division Multiple Access, TDMA), Frequency Division Multiple Access (Frequency Division Multiple Access, FDMA), Orthogonal Frequency Division Multiple Access (OFDMA) , Single-carrier Frequency-Division Multiple Access (Single-carrier Frequency-Division Multiple Access, SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used for the above-mentioned system and radio technology, and can also be used for other systems and radio technologies. The following description describes the New Radio (NR) system for illustrative purposes, and uses NR terminology in most of the following descriptions, but these techniques can also be applied to applications other than NR system applications, such as the 6th generation (6 ^th Generation, 6G) communication system.

In order to facilitate the understanding of the embodiments of this application, the following technical points are introduced first:

1. Signal Amplifier

The signal amplifier (or smart signal amplifier) is used to expand the coverage of the cell, including receiving and amplifying the downlink signal from the upstream base station, so that the signal strength reaching the terminal (such as the user terminal (User Equipment, UE)) increases; The uplink signal of the UE increases the strength of the uplink signal from the UE to the upstream base station.

The signal amplifier can receive control from the upstream base station, that is, the base station can control the transmission parameters of the signal amplifier, such as the switch and transmission beam of the signal amplifier, so as to improve the working efficiency of the signal amplifier and reduce interference. In the network structure shown in Figure 1, there are three network nodes, and the intermediate network node is a signal amplifier, which includes a terminal module (or called a mobile terminal (Mobile Termination, MT)) and a repeater unit (Repeater Unit , RU), and the signal amplifier does not include only one module in MT or RU. The MT can establish a connection with the upstream base station, and the base station can exchange control signaling with the signal amplifier through the MT, and can instruct the MT/RU of the signal amplifier to transmit/receive related parameters.

2. Timing Advance (TA)

Referring to Figure 2, when the UE sends a signal to the base station, the sending timing of the signal needs to be advanced by a period of time (TA time) relative to its receiving timing, so that the sending signal is aligned with the uplink and downlink timing of the base station after arriving at the base station side through the air interface delay.

The UE timing advance is acquired through the steps stipulated in the protocol. After the UE performs downlink synchronization, it sends a Physical Random Access Channel (Physiacal Random Access Channel, PRACH) according to the downlink timing. The TA field in RAR) notifies the timing advance to the UE. In addition, the base station may also adjust the TA value through a media access control layer (Media Access Control, MAC) control element (Control Element, CE).

In addition, the UE may be configured with multiple TA groups (TA group, TAG), and one or more carrier components (ComponentCarrier, CC) may belong to one TAG, and each TAG includes a TA value. For a UE equipped with multiple CCs, it can support multiple TA values, which belong to different CCs, and can realize the transmission from the UE to the receiving antennas of the base station at different locations.

In addition, the TA of the UE may lose synchronization, and the base station configures a synchronization timer (timer) for the UE. After the timer counts down, the UE determines that the uplink is out of synchronization. After the uplink loses synchronization, the UE can send PRACH for resynchronization.

3. Cyclic prefix (CP)

Due to the multipath effect, the time delay of signal transmission to the receiving end is different, which will cause intersymbol interference. CP technology uses the characteristics of Orthogonal Frequency Division Multiplexing (OFDM) symbols to add CP extensions before useful OFDM symbols, so that when the difference between multipath delays is less than the CP length, inter-symbol interference can be eliminated .

After a signal amplifier is deployed in the network (or after multiple distributed receiving antennas are configured in the network), the delay difference between multipaths will be large, and the CP length cannot offset the multipath delay effect. The schematic diagram of the impulse response delay of the UE is shown in FIG. 3 . The signal amplifier path (repeater path in the figure) is the path after the signal passes through the signal amplifier, and the other paths are paths that do not pass through the signal amplifier. The repeater path cannot be covered by the CP length, so the repeater path and other paths will cause intersymbol interference.

The wireless communication system includes a terminal 41 , a signal amplifier 42 and a network side device 43 . Wherein, the terminal 41 can also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 41 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (PersonalDigital Assistant, PDA), handheld computer, netbook, ultra-mobile personal computer (ultra-mobilepersonal computer, UMPC), mobile Internet device (Mobile Internet Device, MID), wearable device (Wearable Device) or vehicle-mounted equipment (VUE) , Pedestrian Terminal (PUE) and other terminal-side devices, wearable devices include: smart watches, bracelets, earphones, glasses, etc. It should be noted that, the embodiment of the present application does not limit the specific type of the terminal 41 .

The network side device 43 may be a base station or a core network, where a base station may be called a Node B, an evolved Node B, an access point, a base transceiver station (Base TransceiverStation, BTS), a radio base station, a radio transceiver, a basic service set (BasicServiceSet, BSS), Extended Service Set (ExtendedServiceSet, ESS), B Node, Evolved Node B (gNB), Home Node B, Home Evolved Node B, WLAN access point, WiFi node, TransmittingReceiving Point , TRP), wireless access network node, or some other appropriate term in the field, as long as the same technical effect is achieved, the base station is not limited to specified technical terms. It should be noted that, in the embodiments of the present application, only The base station in the NR system is taken as an example, but the specific type of the base station is not limited.

The implementation manner of the present application will be described below in combination with Embodiment 1, Embodiment 2 and Embodiment 3.

Embodiment 1: Downlink Synchronization

In the embodiment of the present application, multiple sets of timings can be set, and transmissions of different paths adopt different timings, so as to overcome the situation that the multipath delay cannot be offset by the CP. Especially for signal transmission on the FR2 frequency, different transmission paths correspond to transmissions in different beam directions, and multiple transmission paths can be maintained between the base station and the terminal at the same time, so as to improve the robustness of transmission.

Referring to Figure 7 and Figure 8, two transmission paths can be maintained between the control node and the terminal at the same time. Transmission path 1 is the control node-signal amplifier-terminal, and the terminal receives the signal on transmission path 1 by receiving timing #1; transmission path 2 is Control node-reflection surface-terminal, the terminal receives the signal on the transmission path 2 at receiving timing #2.

(1) Downlink receiving timing acquisition

The UE adopts the traditional (legacy) synchronization process to determine the downlink receiving timing, but the UE can maintain/use multiple downlink receiving timings (for example, each CC/each TAG includes multiple TAs) according to the strength of the downlink reference signal. For example, one or more times at which a downlink secondary synchronization signal (Secondary Synchronization Signal, SSS)/primary synchronization signal (Primary Synchronization Signal, PSS) demodulation correlation peak value is higher are used as a reference time for downlink receiving timing.

(2) Downlink receiving timing report

In this embodiment of the present application, the UE may maintain/use multiple downlink receiving timings, and the UE reports relevant information of the multiple downlink receiving timings.

Optionally, the relevant information of the multiple downlink receiving timings reported by the UE can reflect the timing difference between the multiple downlink receiving timings, so as to assist the control node in scheduling. That is, the control node avoids resource collision due to the adoption of different downlink receiving timings when the UE receives different transmissions.

Referring to FIG. 9, when the terminal receives slot 1 and slot 2, the offset of the downlink receiving timing relative to the downlink sending timing of the control node is different, resulting in a receiving conflict between slot1 and slot2.

Optionally, when the UE reports the downlink beam to the control node, it also carries relevant information about multiple downlink receiving timings in the direction of the downlink beam.

(3) Downlink transmission

In the case where the UE maintains multiple downlink reception timings at the same time, the method of determining the downlink reception timing corresponding to a certain downlink transmission (such as a Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH)/Physical Downlink Control Channel (PDCCH)) includes one of the following:

a. The UE blindly detects multiple downlink receiving timings;

b. There is a corresponding relationship between the downlink reception timing related information and the downlink beam, and the configuration/scheduling/activation signaling indicating the downlink beam also means indicating the timing corresponding to the downlink reception.

Embodiment 2: Uplink Synchronization

In the embodiment of the present application, the multipath problem is solved by setting multiple sets of transmission timing (or called Timing Advance (TimingAdvance, TA)), and the transmission of different paths uses different TAs to overcome the inability of multipath delay The case of being offset by CP.

(1) Initial TA

Step 1: UE determines reference timing according to downlink synchronization, and sends PRACH according to reference timing.

Optionally, the reference timing is one of downlink receiving timings of the UE.

Optionally, the reference timing cannot be changed within a set period of time. For example, the reference timing cannot be changed before it is determined that the uplink is out of sync.

Step 2: The control node detects the PRACH, determines the TA value (the TA value can be multiple values, and each CC/each TAG includes multiple TAs), and notifies the TA value to the UE.

Optionally, multiple TA values may be carried in the RAR (that is, the enhanced RAR).

Optionally, signaling other than RAR (for example, through downlink control information (Downlink ControlInformation, DCI)/medium access control layer (Medium Access Control, MAC) control element (ControlElement, CE)/radio resource control (Radio Resource Control , RRC) etc.) notify multiple TA values (traditional RAR only carries one TA value).

Step 3: When the UE initiates uplink transmission (for example, message 3 (MSG3) or message B (MSGB)), transmit according to the reference timing and/or the TA notified by the RAR.

Optionally, if the RAR notifies multiple TAs, the UE selects a TA for initial uplink transmission

(a) Choose a TA;

(b) Specific TA, such as minimum TA/maximum TA, etc.;

(c) The first TA in the RAR signaling, etc.

(2) TA adjustment.

One or more of the above TAs are adjusted in a closed loop. For example, the adjustment value of the TA is indicated by the MAC CE, and the way of adjusting the TA by the adjustment value includes one of the following:

(a) Adjust all TAs uniformly (applicable to mobile repeaters)

(b) Adjust TA separately. For example, one adjustment value corresponds to one or more TA values

Optionally, there is an association relationship between the adjustment value and the TA, and the adjustment value and the corresponding TA are explicitly/implicitly associated. For example, set an index (index) for the TA, and adjust the index of the TA corresponding to the adjustment value in the adjustment signaling

(3) Send beam training

Transmit beam training to determine transmit beams and their associated transmit timings (TA).

Optional way 1: UE transmits SRS according to the preset TA, and the control node adopts different receiving timings to blindly detect SRS in a direction of a transmission beam, so as to determine the TA value associated with the uplink beam

For example, 1) The control node configures the SRS resource set; 2) It is assumed that the UE uses different transmission beams for SRS transmission on different SRS resources; 3) It is stipulated that the UE uses the same preset TA to transmit SRS on the SRS resource set.

Optionally, the preset TA is controlled by the control node (for example, the preset TA indicated when configuring the SRS resource set, etc.).

Optional way 2: UE uses different preset TAs to realize the transmission of SRS in a certain transmission beam direction, and the control node detects SRS according to a receiving timing, so as to determine the TA associated with the transmission beam

For example, referring to Figure 10, 1) the control node configures multiple SRS resource sets; 2) assuming that the UE uses different transmission beams for SRS transmission on different SRS resources in one SRS resource set, and on different SRS resource sets, the same SRS The beam direction of the SRS transmitted on the resources of the resource number is repeated; 3) The UE uses different preset TAs to transmit the SRS on different SRS resource sets.

Optionally, the control node demodulates multiple sets of SRS resources, and respectively determines the TA corresponding to each SRS transmission resource (or beam direction).
