Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a method and apparatus for processing timer information and related devices. Background Art

[0002] In a multi-hop Layer 2 (L2) relay network (referred to as a multi-hop relay network), the signaling and data transmission delay between a remote user equipment (UE) and a serving base station depends on the number of hops in the data backhaul path. The larger the number of hops, the longer the transmission delay. For some timers, their running time directly or indirectly covers the time required for the uplink / downlink signaling transmission of the corresponding program flow. Since the time required for the transmission delay of the uplink and downlink signaling in a multi-hop relay network largely depends on the number of hops between the remote UE and the serving base station, the transmission time required for the multi-hop relay network to complete the signaling process may be longer than the running time of the timer. Based on the existing running duration of the timer, the multi-hop relay network may not be able to complete the corresponding signaling transmission during the running of the timer, thereby triggering unnecessary timer timeout behavior.

[0041] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0042] The terms "first", "second", etc. in the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "or" in the present application means at least one of the connected objects. For example, "A or B" covers three scenarios, namely, Scenario 1: including A and not including B; Scenario 2: including B and not including A; Scenario 3: including both A and B. The character " / " generally indicates an "or" relationship between the associated objects before and after.

[0043] The term "indicate" in the present application can be either a direct indication (or an explicit indication) or an indirect indication (or an implicit indication). Among them, a direct indication can be understood as that the sender clearly informs the receiver of specific information, operations to be performed, or request results, etc. in the sent indication; an indirect indication can be understood as that the receiver determines the corresponding information according to the indication sent by the sender, or makes a judgment and determines the operations to be performed or request results, etc. according to the judgment result.

[0044] It should be noted that the technology described in the embodiments of this application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), or other systems. The terms "system" and "network" in the embodiments of this application are often used interchangeably. The described technology can be used not only in the systems and radio technologies mentioned above, but also in other systems and radio technologies. The following description describes the New Radio (NR) system for example purposes and uses NR terms in most of the following descriptions. However, these technologies can also be applied to systems other than the NR system, such as the 6th Generation (6G) communication system.

[0045] Figure 1 A single-hop L2 UE-to-Network (U2N) relay scenario is shown. In this scenario, the remote terminal 11 is connected to the network-side device 13 through the relay terminal 12. Among them, the sidelink refers to the wireless link between UEs in NR / LTE. Two UEs can achieve direct data transmission between them through the sidelink. The wireless link between sidelinks is also called the PC5 link and runs the PC5 protocol. In the related art, research has been conducted on using UEs to provide relay services between the UE and the network. Among them, the UE providing the relay service is called the relay UE (i.e., relay UE), and the UE receiving the ultimate service is called the remote UE. The link between the relay UE and the remote UE is the PC5 link and runs the sidelink interface protocol. The link between the relay UE and the base station is the Uu link and runs the Uu link protocol.

[0046] The control plane of the sidelink radio interface has a PC5 Radio Resource Control (RRC) protocol, which runs above the Packet Data Convergence Protocol (PDCP) layer and the Radio Link Control (RLC) layer. The bottom layer is the Medium Access Control (MAC) layer and the Physical layer. The user plane of the sidelink radio interface from top to bottom includes the Service Data Adaptation Protocol (SDAP), PDCP, RLC, MAC, and Physical (PHY) layer.

[0047] The sidelink U2N relay includes an L2U2N relay and an L3 relay. The former means that the relay UE forwards the data of the remote UE at layer 2, and the latter means that the relay UE forwards the data of the remote UE at layer 3.

[0048] For the user plane protocol stack and control plane protocol stack of the Layer 2U2N relay, see Figure 2 and Figure 3 . The L2 U2N relay introduces a Sidelink Relay Adaptation Protocol (SRAP) layer for data routing. This layer carries the local identification information (local UE ID) of the remote UE and the radio bearer identification information between the remote UE and the base station. Based on this, the relay UE maps the input logical channel to the output logical channel for the forwarded data. For the uplink Protocol Data Unit (PDU) forwarded by the relay UE to the base station, the remote UE adds an SRAP header to the PDU to generate an SRAP PDU. After receiving the SRAP PDU, the relay UE forwards it according to the SRAP header. After receiving the SRAP PDU, the base station determines the corresponding PDCP entity according to the information carried by the SRAP, removes the SRAP header, and submits the corresponding SDU to the PDCP entity. For the downlink PDU forwarded by the relay UE to the remote UE, the base station adds an SRAP header to the PDU to generate an SRAP PDU. After receiving the SRAP PDU, the relay UE forwards it according to the SRAP header. After receiving the SRAP PDU, the remote UE determines the corresponding PDCP entity according to the information carried by the SRAP, removes the SRAP header, and submits the corresponding SDU to the PDCP entity.

[0049] For the L3 U2N relay, data is forwarded at the IP layer, and there is no corresponding improvement in the protocol layer of the RAN, so it will not be elaborated here.

[0050] Figure 4 A multi-hop L2 terminal-to-network (UE-to-Network, U2N) relay scenario is shown. In this scenario, the remote terminal 11 is connected to the network-side device 13 through multiple cascaded relay terminals 12. That is, the uplink and downlink messages of the remote UE need to be relayed through multiple L2 U2N relay UEs to complete the transmission between the remote UE and the base station. The above-mentioned remote terminal can also be described as a U2N remote UE, and the above-mentioned relay terminal 12 can also be described as a U2N relay.

[0051] In a multi-hop L2 U2N network, there will still be an adaptation layer for guiding data forwarding and end-to-end packet identification. The header format and routing mechanism of the adaptation layer may be modified based on those of the adaptation layer in a single-hop L2 U2N network to meet the routing requirements of multiple networks.

[0052] A Remote UE or Relay UE can be referred to as a terminal device or user terminal (User Equipment, UE), which can be a mobile phone, tablet personal computer, laptop computer, notebook computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile Internet device (MID), augmented reality (AR), virtual reality (VR) device, robot, wearable device, flight vehicle, vehicle user equipment (VUE), shipborne equipment, pedestrian user equipment (PUE), smart home (home appliances with wireless communication functions, such as refrigerators, TVs, washing machines or furniture, etc.), game console, personal computer (PC), teller machine or self-service machine, etc. Wearable devices include: smart watches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart ankle chains, etc.), smart wristbands, smart clothing, etc. Among them, vehicle-mounted equipment can also be called vehicle-mounted terminal, vehicle-mounted controller, vehicle-mounted module, vehicle-mounted component, vehicle-mounted chip or vehicle-mounted unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application. The network-side device 12 can include an access network device or a core network device. Among them, the access network device can also be called a radio access network (RAN) device, radio access network function or radio access network unit. The access network device can include a base station, a wireless local area network (WLAN) access point (Access Point, AP) or a wireless fidelity (WiFi) node, etc.Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next-generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), home Node B (HNB), home evolved Node B, Transmission Reception Point (TRP), or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0053] In addition, the following definitions are given for the terms in the multi-hop relay network in the embodiments of this application:

[0054] For the sake of convenience of description, in this application, the multi-hop L2 U2N relay network is simply referred to as the multi-hop relay network. Relative to Figure 5 the remote UE in, the relays therein are classified and defined as follows:

[0055] Host relay: A relay UE that establishes a Uu connection with the serving base station or can establish a Uu connection with the serving base station, and helps the downstream UE forward data and signaling to the base station and forward data and signaling from the base station to the downstream UE;

[0056] Access relay: A relay that establishes a PC5 connection with the remote UE and helps the remote UE forward uplink and downlink data and signaling. It is the access relay for this remote UE.

[0057] Intermediate relay: A relay UE that intervenes between the access relay and the host relay, and helps the remote UE complete the forwarding of data and signaling between the access relay and the host relay. In the multi-hop relay network, there can be 0, 1, or multiple intermediate relays between the access relay and the host relay of a remote UE.

[0058] Downstream UE: All UEs that access the network through a relay UE become the downstream UEs of this relay UE.

[0059] Upstream UE: A relay UE that forwards uplink and downlink data and signaling for a UE is the upstream UE of that UE.

[0060] Sub-UE and parent UE: If relay UE a establishes a PC5 connection with upstream relay UE b to access the network, then relay UE b is the parent UE of UE a, and relay UE a is the sub-UE of UE b.

[0061] Figure 5 In this case, the access relay also has the identity of the remote UE relative to the intermediate relay; and the intermediate relay has the identity of the remote UE relative to the host relay, and so on. This application will not elaborate further hereinafter.

[0062] In the subsequent description of this application, the single-hop L2 U2N relay network is referred to as a single-hop relay network. In a single-hop relay network, the number of hops between the remote UE and the serving base station is fixed at 2 hops (1 hop of PC5 link + 1 hop of Uu link), and the number of hops experienced by uplink and downlink signaling and data transmission is fixed. In a multi-hop L2 relay network (abbreviated as a multi-hop relay network), the signaling and data transmission delay between the remote UE and the serving base station depends on the number of hops in the data backhaul path, and the total number of hops is between 2 and N (N is the maximum number of hops allowed by the network, which can be a finite or infinite value). The larger the number of hops, the longer the transmission delay.

[0063] Next, in conjunction with the accompanying drawings, through some embodiments and their application scenarios, the method for processing timer information provided by the embodiments of this application will be described in detail.

[0064] As Figure 6 shown, the embodiments of this application provide a method for processing timer information, including:

[0065] Step 601: The remote terminal obtains the initial value configuration parameter of the timer and the hop count information, where the hop count information is used to determine the first hop count, and the first hop count is the backhaul hop count of the backhaul link in the relay network, and the initial value configuration parameter is related to the backhaul hop count in the backhaul link.

[0066] Optionally, the relay network is a multi-hop relay network.

[0067] Optionally, the first hop count includes the total hop count of the backhaul link in the relay network or the hop count based on the PC5 link in the backhaul link.

[0068] Optionally, the above-mentioned backhaul link is the backhaul link between the remote terminal and the network-side device in the relay network.

[0069] In the embodiments of this application, after the remote terminal obtains the above-mentioned hop count information, it determines the first hop count according to the hop count information.

[0070] In the embodiments of the present application, the initial value configuration parameter can be obtained from a network-side device according to a system message or an RRC message. For example, a relay UE within the coverage of a base station signal receives a system message containing the initial value configuration parameter from the base station and forwards the system message to downstream relay UEs and remote UEs. After receiving the system message from an upstream relay UE, a relay UE forwards the system message to downstream relay UEs and remote UEs.

[0071] Step 602: The remote terminal determines an initial value of a timer according to the initial value configuration parameter and the first hop count, and the initial value is used to determine an operating duration of the timer.

[0072] As an implementation manner, the above initial value is the operating duration of the timer.

[0073] Optionally, the above timer is a timer in the prior art or can be a newly defined timer.

[0074] In the embodiments of the present application, the remote terminal determines the initial value of the timer based on the initial value configuration parameter related to the backhaul hop count in the backhaul link and the backhaul hop count of the backhaul link in the relay network. Thus, the purpose of determining the operating duration of the timer based on the backhaul hop count in the backhaul link is achieved, so that the operating duration of the timer can match the transmission time required by the signaling process corresponding to the timer in the relay network, thereby being able to avoid or reduce the phenomenon that the remote terminal fails to complete the corresponding signaling transmission during the operation of the timer due to an inappropriate setting of the operating duration of the timer, triggering unnecessary timer timeout behaviors. Furthermore, the number of link interruptions can be effectively reduced, the power consumption of the terminal can be lowered, etc., improving the wireless connection management performance.

[0075] Optionally, the remote terminal determines the initial value of the timer according to the initial value configuration parameter and the first hop count, including:

[0076] The remote terminal determines a second hop count according to the first hop count, and the second hop count is a hop count associated with the initial value of the timer;

[0077] The remote terminal determines the initial value of the timer according to the second hop count and the initial value configuration parameter.

[0078] Here, the remote terminal determines the second hop count related to the initial value of the timer based on the obtained first hop count, and then determines the initial value of the timer based on the second hop count and the initial value configuration parameter, so that the operating duration of the timer can match the transmission time of the corresponding signaling process in the relay network, avoiding triggering unnecessary timer timeout behaviors.

[0079] Optionally, the remote terminal determines a second hop count according to the first hop count, including at least one of the following:

[0080] The first item: when the first hop count is the total backhaul hop count of the backhaul link between the remote terminal and the network side device in the relay network, determining the first hop count as the second hop count;

[0081] The second item: when the first hop count is the total backhaul hop count of the backhaul link between the remote terminal and the network side device in the relay network, determining the second hop count according to the hop count based on the PC5 connection in the backhaul link;

[0082] The third item: when the first hop count is the total backhaul hop count of the backhaul link between the remote terminal and the network side device in the relay network, determining the second hop count according to the first hop count and a first adjustment value;

[0083] The fourth item: when the first hop count is the backhaul hop count based on the PC5 connection in the backhaul link between the remote terminal and the network side device in the relay network, determining the first hop count as the second hop count;

[0084] The fifth item: when the first hop count is the backhaul hop count based on the PC5 connection in the backhaul link between the remote terminal and the network side device in the relay network, determining the second hop count according to the first hop count and a second adjustment value;

[0085] The sixth item: when the first hop count is the backhaul hop count based on the PC5 connection in the backhaul link between the remote terminal and the network side device in the relay network minus a third adjustment value, determining the first hop count as the second hop count;

[0086] Wherein, the first adjustment value, the second adjustment value and the third adjustment value are all pre-configured integers, and the first adjustment value, the second adjustment value and the third adjustment value may be the same or different.

[0087] As an implementation manner, the above first adjustment value, second adjustment value and third adjustment value are all 1.

[0088] For the above first item, determining the total backhaul hop count of the backhaul link between the remote terminal and the network side device in the relay network as the second hop count. Subsequently, the initial value of the timer can be determined according to the increased delay amount corresponding to each hop in the second hop count. Assume that the second hop count is N, the increased delay amount corresponding to each hop in the second hop count is △, and the initial value of the timer is T0, then This ensures that the running duration of the timer can match the transmission time of the signaling process corresponding to the timer in the entire relay network. Wherein, 1 ≤ i ≤ N, and i is a positive integer.

[0089] For the second item above, the number of hops based on PC5 connection in the backhaul link is the value obtained by subtracting 1 from the total number of hops. That is, the number of hops based on PC5 connection in the backhaul link is determined as the second number of hops. Subsequently, the initial value of the timer can be determined according to the running duration of the timer in the backhaul link between the remote terminal and the network-side device when the backhaul link includes one-hop Uu link in the initial value configuration parameters, the second number of hops, and the delay increment corresponding to each hop in the second number of hops. Assume that the second number of hops is N, the delay increment corresponding to each hop is △, the running duration of the above one-hop Uu link is X, and the initial value of the timer is T0. Then This ensures that the running duration of the timer can match the transmission time of the signaling process corresponding to the timer in the entire relay network. Where 1 ≤ i ≤ N, and i is a positive integer.

[0090] For the third item above, determining the second number of hops according to the first number of hops and the first adjustment value may include subtracting the value after the first adjustment from the first number of hops as the second number of hops. For example, if the first adjustment value is 1, in this case, the initial value of the timer can be determined according to the running duration of the timer in the backhaul link between the remote terminal and the network-side device when the backhaul link includes one-hop Uu link in the initial value configuration parameters (this running duration can also be described as the running duration of the timer in the non-relay network), the second number of hops, and the delay increment corresponding to each hop in the second number of hops. Assume that the second number of hops is N, the delay increment corresponding to each hop is △, the running duration of the above one-hop Uu link is X, and the initial value of the timer is T0. Then This ensures that the running duration of the timer can match the transmission time of the signaling process corresponding to the timer in the entire relay network. Where 1 ≤ i ≤ N, and i is a positive integer.

[0091] For the fourth item above, determining the above second number of hops for the number of backhaul hops based on PC5 connection in the backhaul link. Subsequently, the initial value of the timer can be determined based on the running duration of the timer in the backhaul link between the remote terminal and the network-side device when the backhaul link includes one-hop Uu link in the initial value configuration parameters, the second number of hops, and the delay increment corresponding to each hop in the second number of hops. Assume that the second number of hops is N, the delay increment corresponding to each hop is △, the running duration of the above one-hop Uu link is X, and the initial value of the timer is T0. Then This ensures that the running duration of the timer can match the transmission time of the signaling process corresponding to the timer in the entire relay network. Where 1 ≤ i ≤ N, and i is a positive integer.

[0092] For the above fifth item, determining the second hop count based on the backhaul hop count of the PC5 connection and the second adjustment value may include: using the value obtained by subtracting the second adjustment value from the backhaul hop count of the PC5 connection as the second hop count. For example, if the second adjustment value is 1, in this case, the initial value of the timer can be determined according to the running duration of the timer in the single-hop relay network, the second hop count, and the delay increment corresponding to each hop in the second hop count. Assume the second hop count is N, the delay increment corresponding to each hop is Δ, the running duration of the above timer in the single-hop relay network is Y, and the initial value of the timer is T0, then This ensures that the running duration of the timer can match the transmission time of the signaling process corresponding to the timer in the entire relay network. Where 1 ≤ i ≤ N, and i is a positive integer.

[0093] For the above sixth item, using the value obtained by subtracting the third adjustment value from the backhaul hop count of the PC5 connection in the backhaul link as the second hop count. For example, using the value obtained by subtracting 1 from the backhaul hop count of the PC5 connection in the backhaul link as the second hop count. In this case, the initial value of the timer can be determined according to the running duration of the timer in the single-hop relay network, the second hop count, and the delay increment corresponding to each hop in the second hop count. Assume the second hop count is N, the delay increment corresponding to each hop is Δ, the running duration of the above timer in the single-hop relay network is Y, and the initial value of the timer is T0, then This ensures that the running duration of the timer can match the transmission time of the signaling process corresponding to the timer in the entire relay network. Where 1 ≤ i ≤ N, and i is a positive integer.

[0094] In the embodiments of the present application, the second hop count related to the initial value of the timer is determined based on the first hop count indicated by the above hop count information. Different second hop counts use different methods to determine the initial value of the timer, so as to ensure that the running duration of the timer can match the transmission time of the signaling process corresponding to the timer in the entire relay network.

[0095] As an implementation, the initial value configuration parameter includes a first initial value, and the first initial value is the running duration of the timer when the backhaul link between the remote terminal and the network-side device includes one-hop Uu link or includes one-hop Uu link and one-hop PC5 link.

[0096] Optionally, the remote terminal determines the initial value of the timer according to the second hop count and the initial value configuration parameter, including:

[0097] Determining the adjustment value corresponding to the initial value of the timer according to the second hop count and the delay increment corresponding to each hop in the second hop count;

[0098] Determine the initial value of the timer according to the initial value configuration parameter and the adjustment value.

[0099] Exemplarily, the above adjustment value is obtained according to the sum of the delay increase amounts corresponding to each hop in the second hop count; Exemplarily, the initial value of the above timer is obtained based on the sum of the first initial value and the adjustment value.

[0100] It should be noted that the delay increase amounts corresponding to different hops in the second hop count may be the same or different. The delay increase amount corresponding to each hop above is determined based on the duration required for signaling transmission or processing.

[0101] As an implementation manner, the initial value configuration parameter includes the association relationship between the hop count of the backhaul link and the initial value of the timer.

[0102] Optionally, the backhaul hop count of the backhaul link in the association relationship includes at least one of the following:

[0103] The first hop count; For example, the total backhaul hop count of the backhaul link between the remote terminal and the network side device in the relay network (including the hop count based on the Uu connection and the hop count based on the PC5 connection), the backhaul hop count based on the PC5 connection in the backhaul link between the remote terminal and the network side device in the relay network, or the hop count after subtracting 1 from the backhaul hop count based on the PC5 connection;

[0104] The second hop count; For example, the total backhaul hop count of the backhaul link between the remote terminal and the network side device in the relay network (including the hop count based on the Uu connection and the hop count based on the PC5 connection), the backhaul hop count based on the PC5 connection in the backhaul link between the remote terminal and the network side device in the relay network, or the hop count after subtracting 1 from the backhaul hop count based on the PC5 connection.

[0105] Optionally, the association relationship includes the correspondence relationship between the backhaul hop count of the backhaul link and the initial value of the timer; Exemplarily, there is a one-to-one correspondence between the backhaul hop count and the initial value of the timer in the association relationship, or, multiple backhaul hop counts in the association relationship correspond to one initial value of the timer;

[0106] Alternatively, the association relationship includes the correspondence relationship between the hop count range of the backhaul link and the initial value of the timer.

[0107] For example, the first hop count range corresponds to the initial value 1, and this first hop count range includes 1 hop and 2 hops; the second hop count range corresponds to the initial value 2, and this second hop count range includes 3 hops and 4 hops; the third hop count range corresponds to the initial value 3, and this third hop count range includes 5 hops and hop counts greater than 5 hops.

[0108] Optionally, the remote terminal determines the initial value of the timer according to the initial value configuration parameter and the second hop count, including:

[0109] The remote terminal obtains the initial value of the timer corresponding to the second hop count based on the association relationship;

[0110] Determine the initial value of the timer corresponding to the second hop count as the initial value of the timer.

[0111] In the embodiment of the present application, for the above-mentioned timer, the corresponding association relationship is configured by the network. When the remote terminal starts the timer, it searches for the corresponding initial value of the timer according to the above-mentioned second hop count, and determines the running duration of the timer based on this.

[0112] It should be noted that in the embodiment of the present application, one association relationship can correspond to each timer, or multiple timers can correspond to one association relationship.

[0113] Optionally, the method of the embodiment of the present application further includes:

[0114] When the first hop count indicates that the hop count based on the PC5 link in the relay network is 1, determine the initial value of the timer according to the running duration of the configured timer in the single-hop relay network.

[0115] Here, when the first hop count indicates that the hop count based on the PC5 link in the relay network is 1, directly use the running duration of the timer configured by the network in the single-hop relay network to determine the initial value of the timer.

[0116] Optionally, the remote terminal obtains hop count information, including:

[0117] The remote terminal obtains the hop count information sent by the network-side device or the relay terminal; optionally, the relay terminal includes a host relay or an access relay;

[0118] Alternatively, the remote terminal obtains the hop count information from the SRAP header of the side link relay adaptation protocol (SRAP) protocol data unit (PDU). Optionally, the SRAP header includes the hop count information experienced by the data or signaling.

[0119] As an implementation manner, the remote terminal obtains hop count information, including:

[0120] The remote terminal obtains the hop count information through a system message, a Uu radio resource control (RRC) message, a PC5 RRC message, a discovery message, or a proximity services (Prose S) message.

[0121] Optionally, the method of the embodiment of the present application further includes:

[0122] When the remote terminal repeats the transmission of the signaling corresponding to the timer through multiple backhaul links, perform a first operation;

[0123] Wherein, the first operation includes one of the following:

[0124] A1: After sending the signaling on each backhaul link, respectively start one of the timers corresponding to the backhaul link, and when the timers corresponding to all backhaul links time out, perform the action triggered by the timeout of the timer.

[0125] In this item, each backhaul link corresponds to a separate one of the timers. Since the remote terminal performs repeated transmission of the same signaling at different times on different backhaul links, using separate timers is beneficial for the UE to manage the signaling transmission time of each backhaul link respectively.

[0126] A2: After sending the signaling on each backhaul link, if the timers corresponding to the multiple backhaul links are not in the running state, start the timers corresponding to the multiple backhaul links; if the timers corresponding to the multiple backhaul links are in the running state, restart the timers corresponding to the multiple backhaul links; wherein, the initial value of the timer is determined based on the first hop count or the second hop count of the corresponding backhaul link at each start or restart.

[0127] In this item, the transmission of one piece of signaling corresponds to one timer. By making the transmission of each piece of signaling correspond to one timer, it is convenient to control the transmission time of each piece of signaling.

[0128] A3: After sending the first copy of the signaling through the backhaul link, if the timers corresponding to the multiple backhaul links are not in the running state, start the timers corresponding to the multiple backhaul links.

[0129] In this item, the transmission of one piece of signaling corresponds to one timer. The copy of the signaling is the repeatedly transmitted signaling, and in this item, when sending other copies of the signaling except the first copy, the corresponding timer is not started, so as to facilitate the control of the transmission time of the copy of the signaling.

[0130] Optionally, when the relay network includes at least two backhaul links, the first hop count or the second hop count is the first hop count or the second hop count corresponding to the first backhaul link, and the first backhaul link is a backhaul link selected by the remote terminal in the relay network for transmitting signaling;

[0131] Alternatively, in the case where the relay network includes at least two backhaul links, the first hop count or the second hop count is the first hop count or the second hop count corresponding to the second backhaul link, and the second backhaul link is the backhaul link with the largest first hop count or second hop count among the at least two backhaul links selected by the remote terminal in the relay network.

[0132] Optionally, the backhaul links in the relay network include single-hop relay transmission paths or multi-hop relay transmission paths. Optionally, the backhaul link further includes a non-relay transmission path.

[0133] Optionally, the timer includes at least one of the following:

[0134] B1: A timer for managing the wireless link establishment process; for example, T300;

[0135] B2: A timer for managing the wireless link reconstruction process; for example, T301;

[0136] B3: A timer for managing the main cell group (MCG) failure message reporting process; for example, T316;

[0137] B4: A timer for managing the process in which the terminal sends user equipment assistance information (UAI) containing a connection release request; for example, T346f;

[0138] B5: A timer for managing the process in which a terminal in the RRC connected state requests system information by means of a dedicated message; for example, T350;

[0139] B6: A timer for managing the RRC reconfiguration process including relay link handover; for example, T420;

[0140] B7: A timer for managing the wireless connection continuation process, such as T319.

[0141] For item B1 above, the timer is used to configure the time range for completing the wireless link establishment process. It is started after the UE sends a wireless link establishment request (RRC Setup Request) and terminated when the UE receives a response from the peer or determines to abandon the wireless link establishment process for various reasons. When the timer expires, the UE considers the wireless link establishment to have failed, resets the MAC layer, and notifies the relevant protocol modules;

[0142] For a single-hop relay network, the initial value of T300 for the L2 remote UE is configured by the dedicated parameter t300-RemoteUE of the remote UE.

[0143] For item B2 above, the timer is used to configure the time range for completing the radio link reestablishment procedure. It starts after the UE sends a Radio Link Reestablishment Request and stops when a response from the peer is received or when it is determined that the target serving node (e.g., the target cell or target relay) is unavailable. When this timer expires, the UE considers the radio link reestablishment to have failed and enters the RRC_IDLE state;

[0144] For a single-hop relay network, the initial value of T301 for the L2 remote UE is configured by the dedicated parameter t301-RemoteUE of the remote UE.

[0145] For item B3 above, the timer is used to manage the time range for the procedure of reporting the Master Cell Group (MCG) Failure Information. It starts after sending the MCG Failure Information and stops when a response message from the base station is received. If T316 expires, a radio link reestablishment procedure is initiated.

[0146] For a single-hop relay network, the initial value of T319 for the L2 remote UE is configured by the dedicated parameter t319-RemoteUE of the remote UE.

[0147] For item B4 above, the timer is used to prevent the UE from frequently sending User Equipment Assistance Information (UAI) messages that contain a release connection request (which can also be described as a release preference). The UE starts the timer after sending a UAI message that contains a release connection request and stops it when a release preference configuration (Config) is received or when radio link reestablishment or continuation occurs.

[0148] For item B5 above: The timer is used to limit the UE in the RRC_CONNECTED state from frequently initiating Dedicated System Information Block (SIB) Requests. After the UE sends a system information request, T350 is started, and during the running of T350, no more Dedicated SIB Requests are initiated; the UE stops T350 after receiving the requested system information.

[0149] For the above item B6: The time range for configuring the RRC reconfiguration message (RRCReconfiguration) that completes the relay link switch (sl-PathSwitchConfig) is started when the remote UE receives the RRC reconfiguration message, and the substantial condition for stopping is that the target relay link is successfully established. In the existing standard, it is reflected as stopping when the reconfiguration is completed (for example, when the RRC reconfiguration complete message RRCReconfigurationComplete is successfully sent through the target relay link). Its initial value is configured in SL-PathSwitchConfig.

[0150] The timeout of T420 indicates the failure of the relay link switch, and the UE will initiate a radio link reconstruction process.

[0151] For the above item B7, the timer is used to manage the time range for completing the radio connection resume process (RRC Resume). It is started after the UE sends a radio link resume request (RRC Resume Request / RRC ResumeRequest1) and stopped after the UE receives the corresponding response message. If T319 times out, the UE falls back to the RRC_IDLE state.

[0152] The timer in the embodiments of this application can also be other timers. For example, a timer used to manage the MCG failure information reporting process is not specifically limited in this application.

[0153] In the embodiments of this application, the remote terminal determines the initial value of the timer based on the initial value configuration parameter related to the number of backhaul hops in the backhaul link and the number of backhaul hops of the backhaul link in the relay network. Thus, the purpose of determining the running duration of the timer based on the number of backhaul hops in the backhaul link is achieved, enabling the running duration of the timer to match the transmission time required for the signaling process corresponding to the timer in the relay network. Thereby, it can avoid or reduce the phenomenon that the remote terminal cannot complete the corresponding signaling transmission during the running of the timer due to the setting of an inappropriate timer running duration, triggering unnecessary timer timeout behaviors. Furthermore, it can effectively reduce the number of link interruptions, reduce the power consumption of the terminal, etc., and improve the radio connection management performance.

[0154] As Figure 7 shown, the embodiments of this application also provide a method for processing timer information, including:

[0155] Step 701: The network-side device sends the initial value configuration parameter of the timer, and the initial value configuration parameter is related to the number of hops of the backhaul link in the relay network.

[0156] The network-side device is the network-side device in the relay network.

[0157] Optionally, the relay network is a multi-hop relay network.

[0158] In the embodiments of the present application, the initial value configuration parameter may be sent according to a system message or an RRC message. For example, a relay UE within the coverage of a base station signal receives a system message containing the initial value configuration parameter from the base station and forwards the system message to a downstream relay UE and a remote UE. After receiving the system message from an upstream relay UE, a relay UE forwards the system message to a downstream relay UE and a remote UE.

[0159] In the embodiments of the present application, a network-side device sends an initial value configuration parameter related to the number of hops of a backhaul link in a relay network, so that a remote terminal can determine an initial value of a timer based on the initial value configuration parameter and the number of backhaul hops of the backhaul link in the relay network. Thus, the purpose of determining the running duration of the timer based on the number of backhaul hops in the backhaul link is achieved, such that the running duration of the timer can match the transmission time required for a signaling process corresponding to the timer in the relay network, thereby avoiding or reducing the phenomenon that a remote terminal fails to complete corresponding signaling transmission during the running of the timer due to an inappropriate setting of the running duration of the timer, which triggers an unnecessary timer timeout behavior. Furthermore, the number of link interruptions can be effectively reduced, the power consumption of the terminal can be reduced, etc., improving the performance of wireless connection management.

[0160] Optionally, the initial value configuration parameter includes a first initial value, which is the running duration of the timer when the link between the remote terminal and the network-side device includes one-hop Uu link or includes one-hop Uu link and one-hop PC5 link;

[0161] Alternatively, the initial value configuration parameter includes an association relationship between the number of hops of a backhaul link and the initial value of the timer.

[0162] Optionally, the number of backhaul hops of the backhaul link in the association relationship includes at least one of the following:

[0163] A first number of hops, which is the number of backhaul hops of the backhaul link in the relay network;

[0164] A second number of hops, which is the number of hops associated with the initial value of the timer.

[0165] Optionally, the association relationship includes a correspondence between the number of hops of a backhaul link and the initial value of the timer;

[0166] Alternatively, the association relationship includes a correspondence between a range of the number of hops of a backhaul link and the initial value of the timer.

[0167] This association relationship has been described in the method embodiments on the remote terminal side and will not be elaborated here.

[0168] Optionally, the method according to an embodiment of the present application further includes:

[0169] The network side device sends hop count information, and the hop count information is used for the remote terminal to determine a first hop count, where the first hop count is the backhaul hop count of the backhaul link in the relay network.

[0170] Here, the network side device sends hop count information, so that the remote terminal can determine a second hop count related to the initial value of the timer according to the first hop count, and further determine the initial value of the timer based on the second hop count and the initial value configuration parameter.

[0171] As an implementation manner, the network side device sending the hop count information includes:

[0172] The network side device sends the hop count information through a system message or a Uu radio resource control (RRC) message.

[0173] Optionally, in the case that the relay network includes at least two backhaul links, the first hop count or the second hop count is the first hop count or the second hop count corresponding to the first backhaul link, and the first backhaul link is a backhaul link selected by the remote terminal in the relay network for transmitting signaling;

[0174] Or, in the case that the relay network includes at least two backhaul links, the first hop count or the second hop count is the first hop count or the second hop count corresponding to the second backhaul link, and the second backhaul link is the backhaul link with the largest first hop count or second hop count among at least two backhaul links selected by the remote terminal in the relay network.

[0175] In the embodiment of the present application, the network side device sends an initial value configuration parameter related to the hop count of the backhaul link in the relay network, so that the remote terminal can determine the initial value of the timer based on the initial value configuration parameter and the backhaul hop count of the backhaul link in the relay network. Thus, the purpose of determining the running duration of the timer based on the backhaul hop count in the backhaul link is achieved, so that the running duration of the timer can match the transmission time required for the signaling process corresponding to the timer in the relay network, thereby avoiding or reducing the phenomenon that the remote terminal cannot complete the corresponding signaling transmission during the running of the timer due to the setting of an inappropriate running duration of the timer and triggering an unnecessary timer timeout behavior. Furthermore, the number of link interruptions can be effectively reduced, the power consumption of the terminal can be reduced, etc., and the wireless connection management performance can be improved.

[0176] As Figure 8 shown, the embodiment of the present application further provides a method for processing timer information, including:

[0177] Step 801: The relay terminal sends hop count information, which is used by the remote terminal to determine a first hop count, where the first hop count is the hop count of the backhaul link in the relay network.

[0178] Optionally, the relay terminal includes a host relay or an access relay.

[0179] Optionally, the hop count information sent by the relay terminal is used to indicate the hop count information of the backhaul link between the network side device and the relay terminal, such as the total hop count of the backhaul link between the network side device and the relay terminal, or the hop count based on the PC5 connection in the backhaul link between the network side device and the relay terminal.

[0180] As an implementation, the relay terminal sending the hop count information includes:

[0181] The relay terminal sends the hop count information through a system message, a PC5 RRC message, a discovery message, or a proximity service message.

[0182] For example, the host relay sends the hop count information through a proximity service message or a PC5 RRC message, and the access relay sends the hop count information through a discovery message, a proximity service message, or a PC5 RRC message.

[0183] In the embodiments of the present application, the relay terminal sends hop count information, which is used by the remote terminal to determine a first hop count, where the first hop count is the hop count of the backhaul link in the relay network. Thus, the remote terminal can determine the initial value of the timer based on the initial value configuration parameter related to the hop count in the backhaul link and the hop count of the backhaul link in the relay network. Thus, the purpose of determining the running duration of the timer based on the hop count in the backhaul link is achieved, so that the running duration of the timer can match the transmission time required for the signaling process corresponding to the timer in the relay network, thereby avoiding or reducing the phenomenon that the remote terminal cannot complete the corresponding signaling transmission during the running of the timer due to the setting of an inappropriate timer running duration and triggering unnecessary timer timeout behaviors. Furthermore, it can effectively reduce the number of link interruptions, reduce the power consumption of the terminal, etc., and improve the wireless connection management performance.
