[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202311861606.X filed in China on December 29, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a method, apparatus and related equipment for processing timer information. Background Art

[0004] In a multi-hop Layer 2 (L2) relay network (abbreviated 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 return path. The greater the number of hops, the longer the transmission delay. The running time of some timers 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 of the 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.

Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0045] The term "indication" in this application can be either a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, the operation to be performed, or the requested result, etc. in the instruction sent; an indirect indication can be understood as the receiver determining the corresponding information based on the instruction sent by the sender, or making a judgment and determining the operation to be performed or the requested result, etc. based on the judgment result.

[0046] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, 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 the present application are often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than NR systems, such as 6th Generation (6G) communication systems.

[0047] Figure 1 shows a single-hop L2 terminal-to-network (UE-to-Network, U2N) relay scenario. 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 UE and UE in NR / LTE, and the two UEs can realize direct data transmission between them through the sidelink. The wireless link between the sidelinks is also called the PC5 link, which runs the PC5 protocol. In related technologies, the use of UE to provide relay services between UE and network will be studied, wherein the UE providing relay services is called relay UE (i.e. relay UE), and the UE provided with the ultimate service is called remote UE (remote UE). The link between the relay UE and the remote UE is a PC5 link, which runs the sidelink interface protocol, and the link between the relay UE and the base station is a Uu link, which runs the Uu link protocol.

[0048] The sidelink radio interface control plane consists of the PC5 Radio Resource Control (RRC) protocol, running above the Packet Data Convergence Protocol (PDCP) and Radio Link Control (RLC) layers, with the Media Access Control (MAC) and physical layers at the bottom. The sidelink radio interface user plane, from top to bottom, consists of the Service Data Adaptation Protocol (SDAP), PDCP, RLC, MAC, and physical layers.

[0049] Sidelink U2N relay includes L2U2N relay and L3 relay. The former refers to the relay UE forwarding the data of the remote UE at layer 2, and the latter refers to the relay UE forwarding the data of the remote UE at layer 3.

[0050] The user plane protocol stack and control plane protocol stack of Layer 2U2N relay are shown in Figures 2 and 3. The L2U2N relay introduces the Sidelink Relay Adaptation Protocol (SRAP) layer for data routing. This layer carries the local UE ID of the remote UE and the radio bearer identification information between the remote UE and the base station. The relay UE uses this information to map the input logical channel to the output logical channel for forwarded data. For uplink protocol data units (PDUs) forwarded to the base station via the relay UE, 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 based on the SRAP header. After receiving the SRAP PDU, the base station determines the corresponding PDCP entity based on the information carried by the SRAP, removes the SRAP header, and submits the corresponding SDU to the PDCP entity. For the downlink PDU forwarded to the remote UE via the relay 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 based on the information carried by the SRAP, removes the SRAP header, and submits the corresponding SDU to the PDCP entity.

[0051] For L3U2N relay, data is forwarded at the Internet Protocol (IP) layer. There is no corresponding improvement in the protocol layer of the Radio Access Network (RAN), which is not described here.

[0052] Figure 4 illustrates a multi-hop L2 UE-to-Network (U2N) relay scenario. In this scenario, a remote terminal 11 is connected to a network-side device 13 via multiple serially connected relay terminals 12. This means that uplink and downlink messages from the remote UE must be relayed between multiple L2U2N relay UEs to complete transmission between the remote UE and the base station. The remote terminal can also be described as a U2N remote UE, and the relay terminal 12 can also be described as a U2N relay.

[0053] In a multi-hop L2U2N network, an adaptation layer will still be present to guide data forwarding and identify end-to-end data packets. The packet header format and routing mechanism of the adaptation layer may be modified as necessary based on the adaptation layer of a single-hop L2U2N network to accommodate the routing requirements of multiple networks.

[0054] Remote UE or Relay UE can be called terminal equipment or 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 capabilities, such as refrigerators, TVs, washing machines or furniture, etc.), game consoles, personal computers (PC), ATMs or self-service machines and other terminal-side devices. Wearable devices include: smart watches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. Among them, the vehicle-mounted device can also be called a vehicle-mounted terminal, a vehicle-mounted controller, a vehicle-mounted module, a vehicle-mounted component, a vehicle-mounted chip or a vehicle-mounted unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 may include an access network device or a core network device, wherein the access network device may also be called a radio access network (Radio Access Network, RAN) device, a radio access network function or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) 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 (home evolved Node B), Transmission Reception Point (TRP) or other appropriate terms in the relevant field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0055] In addition, the following definitions are given for the terms in the multi-hop relay network in the embodiments of the present application:

[0056] For ease of description, in this application, a multi-hop L2U2N relay network is referred to as a multi-hop relay network. Relative to the remote UE in FIG5 , the relays therein are classified and defined as follows:

[0057] Host relay: A relay UE that establishes or can establish a Uu connection with a serving base station, helps downstream UEs forward data and signaling to the base station, and forwards data and signaling from the base station to downstream UEs;

[0058] Access relay: Establishes a PC5 connection with a remote UE and helps the remote UE forward uplink and downlink data and signaling. It serves as the access relay for the remote UE.

[0059] Intermediate relays: Relay UEs that intervene between the access relay and the host relay to help remote UEs forward data and signaling between the access relay and the host relay. In a multi-hop relay network, there can be zero, one, or multiple intermediate relays between the access relay and the host relay for a remote UE.

[0060] Downstream UE: All UEs that access the network through a relay UE become downstream UEs of the relay UE.

[0061] Upstream UE: A relay UE that forwards uplink and downlink data and signaling for a UE is the upstream UE of the UE.

[0062] Child UE and parent UE: Relay UE a establishes a PC5 connection with the upstream relay UE b to access the network. Then, relay UE b is the parent UE of UEa, and relay UEa is the child UE of UEb.

[0063] In Figure 5, the access relay also has the identity of a remote UE relative to the intermediate relay; and the intermediate relay has the identity of a remote UE relative to the host relay, and so on. This application will not go into details later.

[0064] In the subsequent description of this application, a single-hop L2U2N 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 PC5 link + 1 hop 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 (referred to 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 return path. 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.

[0065] The following describes in detail the method for processing timer information provided in the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0066] As shown in FIG6 , an embodiment of the present application provides a method for processing timer information, including:

[0067] Step 601: The remote terminal obtains the initial value configuration parameters and hop count information of the timer, where the hop count information is used to determine a first hop count, which is the backhaul hop count of the backhaul link in the relay network. The initial value configuration parameters are related to the backhaul hop count in the backhaul link.

[0068] Optionally, the relay network is a multi-hop relay network.

[0069] Optionally, the first hop count includes the total hop count of a backhaul link in the relay network or the hop count based on a PC5 link in the backhaul link.

[0070] Optionally, the backhaul link is a backhaul link between the remote terminal and the network-side device in the relay network.

[0071] In the embodiment of the present application, after the remote terminal obtains the above-mentioned hop count information, it determines the first hop count according to the hop count information.

[0072] In an embodiment of the present application, the initial value configuration parameters can be obtained from a network-side device based on a system message or an RRC message. For example, a relay UE within the signal coverage of a base station receives a system message containing the initial value configuration parameters from the base station and forwards the system message to downstream relay UEs and remote UEs. After a relay UE receives the system message from an upstream relay UE, it forwards the system message to downstream relay UEs and remote UEs.

[0073] Step 602: The remote terminal determines an initial value of a timer according to the initial value configuration parameter and the first hop count, where the initial value is used to determine the running time of the timer.

[0074] As an implementation manner, the above initial value is the running time of the timer.

[0075] Optionally, the timer is a timer in the related art, or a newly defined timer.

[0076] In an embodiment of the present 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. As a result, the purpose of determining the running duration of the timer based on the number of backhaul hops 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 timer operation due to the setting of an inappropriate timer running duration, thereby triggering unnecessary timer timeout behavior, thereby effectively reducing the number of link interruptions, reducing terminal power consumption, etc., and improving wireless connection management performance.

[0077] Optionally, the remote terminal determining an initial value of a timer according to the initial value configuration parameter and the first hop count includes:

[0078] The remote terminal determines a second hop number based on the first hop number, where the second hop number is a hop number associated with an initial value of the timer;

[0079] The remote terminal determines an initial value of the timer according to the second hop count and the initial value configuration parameter.

[0080] Here, the remote terminal determines the second hop number related to the initial value of the timer based on the obtained first hop number, and then determines the initial value of the timer based on the second hop number and the initial value configuration parameters, so that the running time of the timer can match the transmission time of the corresponding signaling process in the relay network, avoiding triggering unnecessary timer timeout behavior.

[0081] Optionally, the remote terminal determines the second hop number based on the first hop number, including at least one of the following:

[0082] Item 1: when the first hop number is the total backhaul hop number of the backhaul link between the remote terminal and the network-side device in the relay network, determining the first hop number as the second hop number;

[0083] Item 2: 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;

[0084] Item 3: when the first hop number is the total backhaul hop number of the backhaul link between the remote terminal and the network-side device in the relay network, determining the second hop number according to the first hop number and the first adjustment value;

[0085] Item 4: when the first hop number is a backhaul hop number based on a PC5 connection in a backhaul link between the remote terminal and the network-side device in the relay network, determining the first hop number as a second hop number;

[0086] Item 5: when the first hop number is a backhaul hop number based on a PC5 connection in a backhaul link between the remote terminal and the network-side device in the relay network, determining the second hop number according to the first hop number and the second adjustment value;

[0087] Item 6: when the first hop number is the number of backhaul hops 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 number as the second hop number;

[0088] The first adjustment value, the second adjustment value and the third adjustment value are all preconfigured integers, and the first adjustment value, the second adjustment value and the third adjustment value may be the same or different.

[0089] As an implementation manner, the first adjustment value, the second adjustment value and the third adjustment value are all 1.

[0090] For the first item above, the total number of return hops of the return link between the remote terminal and the network-side device in the relay network is determined as the second number of hops. Subsequently, the initial value of the timer can be determined according to the delay increase corresponding to each hop in the second number of hops. Assuming that the second number of hops is N, the delay increase corresponding to each hop in the second number of hops is △, and the initial value of the timer is T0, then This ensures that the running time 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.

[0091] For the second item above, the number of hops based on the PC5 connection in the backhaul link is the value after subtracting 1 from the total number of hops, that is, the number of hops based on the PC5 connection in the backhaul link is determined as the second hop number. Subsequently, the initial value of the timer can be determined according to the running time of the timer in the initial value configuration parameter when the backhaul link between the remote terminal and the network side device includes a one-hop Uu link, the second hop number, and the delay increase corresponding to each hop in the second hop number. Assuming that the second hop number is N, the delay increase corresponding to each hop is △, the running time corresponding to the above-mentioned one-hop Uu link is X, and the initial value of the timer is T0, then This ensures that the running time 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.

[0092] For the third item above, determining the second hop number based on the first hop number and the first adjustment value may include subtracting the first adjusted value from the first hop number as the second hop number. For example, if the first adjustment value is 1, then in this case, the initial value of the timer can be determined based on the running time of the timer in the initial value configuration parameter when the backhaul link between the remote terminal and the network side device includes a one-hop Uu link (the running time can also be described as the running time of the timer in the non-relay network), the second hop number, and the delay increase corresponding to each hop in the second hop number. Assuming that the second hop number is N, the delay increase corresponding to each hop is △, the running time corresponding to the above-mentioned one-hop Uu link is X, and the initial value of the timer is T0, then This ensures that the running time 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.

[0093] For the fourth item above, the second hop number is determined based on the number of backhaul hops based on the PC5 connection in the backhaul link. Subsequently, the initial value of the timer can be determined based on the running time of the timer in the initial value configuration parameter when the backhaul link between the remote terminal and the network side device includes a one-hop Uu link, the second hop number, and the delay increase corresponding to each hop in the second hop number. Assuming that the second hop number is N, the delay increase corresponding to each hop is △, the running time corresponding to the one-hop Uu link is X, and the initial value of the timer is T0, then This ensures that the running time 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.

[0094] For the fifth item above, determining the second hop count based on the return hop count of the PC5 connection and the second adjustment value may include: taking the value obtained by subtracting the second adjustment value from the return hop count based on the PC5 connection as the second hop count. For example, if the second adjustment value is 1, then in this case, the initial value of the timer may be determined based on the running time of the timer in the single-hop relay network, the second hop count, and the delay increase corresponding to each hop in the second hop count. Assuming that the second hop count is N, the delay increase corresponding to each hop is △, the running time 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 time 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.

[0095] For the sixth item above, the value obtained by subtracting the third adjustment value from the number of return hops based on the PC5 connection in the return link is used as the second hop number. For example, the value obtained by subtracting 1 from the number of return hops based on the PC5 connection in the return link is used as the second hop number. In this case, the initial value of the timer can be determined based on the running time of the timer in the single-hop relay network, the second hop number, and the delay increase corresponding to each hop in the second hop number. Assuming that the second hop number is N, the delay increase corresponding to each hop is △, the running time 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 time 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.

[0096] In an embodiment of the present application, a second hop number related to the initial value of the timer is determined based on the first hop number indicated by the above-mentioned hop number information, and different second hop numbers are used in different ways to determine the initial value of the timer to ensure that the running time of the timer can match the transmission time of the signaling process corresponding to the timer in the entire relay network.

[0097] As an implementation method, the initial value configuration parameter includes a first initial value, which is the running time of the timer when the backhaul link between the remote terminal to the network side device includes a one-hop Uu link or a one-hop Uu link and a one-hop PC5 link.

[0098] Optionally, the remote terminal determines, according to the second hop count and the initial value configuration parameter, an initial value of the timer, including:

[0099] Determining an adjustment value corresponding to the initial value of the timer according to the second number of hops and the delay increase corresponding to each hop in the second number of hops;

[0100] An initial value of the timer is determined according to the initial value configuration parameter and the adjustment value.

[0101] Exemplarily, the adjustment value is obtained based on the sum of the delay increase corresponding to each hop in the second number of hops; and exemplary, the initial value of the timer is obtained based on the sum of the first initial value and the adjustment value.

[0102] It should be noted that the delay increase corresponding to different hops in the second number of hops is the same or different. The delay increase corresponding to each hop is determined based on the time required for signaling transmission or processing.

[0103] As an implementation manner, the initial value configuration parameter includes an association between the number of hops of the backhaul link and an initial value of the timer.

[0104] Optionally, the backhaul hop count of the backhaul link in the association relationship includes at least one of the following:

[0105] 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;

[0106] 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 Uu connection and the hop count based on PC5 connection), the backhaul hop count based on 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 PC5 connection.

[0107] Optionally, the association relationship includes a correspondence between a backhaul hop count of a backhaul link and an initial value of a timer; illustratively, the backhaul hop count and the initial value of the timer in the association relationship correspond one to one, or, in the association relationship, multiple backhaul hop counts correspond to one initial value of the timer;

[0108] Alternatively, the association relationship includes a correspondence between a hop count range of the backhaul link and an initial value of the timer.

[0109] For example, the first hop count range corresponds to an initial value of 1, and the first hop count range includes 1 hop and 2 hops; the second hop count range corresponds to an initial value of 2, and the second hop count range includes 3 hops and 4 hops; the third hop count range corresponds to an initial value of 3, and the third hop count range includes 5 hops and more than 5 hops.

[0110] Optionally, the remote terminal determines, according to the initial value configuration parameter and the second hop count, an initial value of the timer, including:

[0111] The remote terminal obtains, based on the association relationship, an initial value of a timer corresponding to the second hop count;

[0112] An initial value of the timer corresponding to the second number of hops is determined as the initial value of the timer.

[0113] In an embodiment of the present application, for the association relationship corresponding to the above-mentioned timer configured by the network, when the remote terminal starts the timer, it searches for the corresponding timer initial value according to the above-mentioned second hop count, and determines the running time of the timer based on this.

[0114] It should be noted that, in the embodiment of the present application, each timer may correspond to one association relationship, and multiple timers may correspond to one association relationship.

[0115] Optionally, the method of the embodiment of the present application further includes:

[0116] When the first hop count indicates that the number of hops based on the PC5 link in the relay network is 1, the initial value of the timer is determined according to the configured running time of the timer in the single-hop relay network.

[0117] Here, when the number of hops based on the PC5 link in the first hop number indication relay network is 1, the initial value of the timer is directly determined by using the running time of the timer configured in the network in the single-hop relay network.

[0118] Optionally, the remote terminal acquiring hop count information includes:

[0119] The remote terminal obtains hop count information sent by a network-side device or a relay terminal; optionally, the relay terminal includes a host relay or an access relay;

[0120] Alternatively, the remote terminal obtains the hop count information from a SRAP header of a Sidelink Relay Adaptation Protocol (SRAP) protocol data unit (PDU). Optionally, the SRAP header includes hop count information experienced by the data or signaling.

[0121] As an implementation manner, the remote terminal obtains the hop count information, including:

[0122] 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 service message (Prose S).

[0123] Optionally, the method of the embodiment of the present application further includes:

[0124] When the remote terminal repeatedly transmits signaling corresponding to the timer through multiple backhaul links, performing a first operation;

[0125] The first operation includes one of the following:

[0126] A1: After sending the signaling on each backhaul link, start one of the timers corresponding to the backhaul link respectively, and when the timers corresponding to all the backhaul links expire, execute the action triggered by the timer expiration.

[0127] In this item, each backhaul link corresponds to a separate timer. Since the time for the remote terminal to repeatedly transmit the same signaling on different backhaul links is different, using separate timers is beneficial for the UE to manage the signaling transmission time of each backhaul link separately.

[0128] A2: After sending the signaling on each backhaul link, if the timers corresponding to the multiple backhaul links are not in a running state, start the timers corresponding to the multiple backhaul links; if the timers corresponding to the multiple backhaul links are in a 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 number or the second hop number of the corresponding backhaul link each time it is started or restarted.

[0129] In this item, each transmission of the signaling corresponds to a timer. By corresponding each transmission of the signaling to a timer, it is convenient to control the transmission time of each signaling.

[0130] 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 a running state, start the timers corresponding to the multiple backhaul links.

[0131] In this item, each transmission of the signaling corresponds to a timer. The signaling copy is the signaling that is repeatedly transmitted, and in this item, when other copies of the signaling are sent except the first copy, the corresponding timer is not started to facilitate controlling the transmission time of the signaling copy.

[0132] Optionally, when the relay network includes at least two backhaul links, the first hop number or the second hop number is the first hop number or the second hop number 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;

[0133] Alternatively, in the case where the relay network includes at least two backhaul links, the first hop number or the second hop number is the first hop number or the second hop number corresponding to the second backhaul link, and the second backhaul link is the backhaul link with the largest first hop number or second hop number among the at least two backhaul links selected by the remote terminal in the relay network.

[0134] Optionally, the backhaul link in the relay network includes a single-hop relay transmission path or a multi-hop relay transmission path. Optionally, the backhaul link also includes a non-relay transmission path.

[0135] Optionally, the timer includes at least one of the following:

[0136] B1: a timer used to manage the radio link establishment process; for example, T300;

[0137] B2: a timer used to manage the radio link reestablishment process; for example, T301;

[0138] B3: A timer used to manage the MCG failure message reporting process; for example, T316;

[0139] B4: a timer used to manage the process of the terminal sending the user equipment assistance information UAI containing the release request; for example, T346f;

[0140] B5: a timer used to manage the execution of the system message request procedure by a terminal in the RRC connected state through a dedicated message; for example, T350;

[0141] B6: a timer used to manage the RRC reconfiguration procedure including relay link switching; for example, T420;

[0142] B7: A timer used to manage the wireless connection continuation process, such as T319.

[0143] For item B1 above, the timer is used to configure the time range for completing the radio link establishment process. It starts after the UE sends a radio link establishment request (RRC Setup Request) and ends when it receives a response from the other end or the UE decides to give up continuing the radio link establishment process for various reasons. When the timer expires, the UE considers the radio link establishment failure, resets the MAC layer, and notifies the relevant protocol modules;

[0144] For a single-hop relay network, the initial value of T300 of the L2 remote UE is configured by the remote UE's dedicated parameter t300-RemoteUE.

[0145] For item B2 above, the timer is used to configure the time range for completing the radio link reestablishment process. It starts after the UE sends a radio link reestablishment request (RRC Reestablishment Request) and stops when it receives a response from the other end or determines that the target serving node (such as the target cell or target relay) is unavailable. When the timer expires, the UE considers the radio link reestablishment failed and enters the RRC_IDLE state;

[0146] For a single-hop relay network, the initial value of T301 of the L2 remote UE is configured by the remote UE-specific parameter t301-RemoteUE.

[0147] For item B3 above, the timer is used to manage the time range for completing the processing of Master Cell Group (MCG) Failure Information reports. It starts after the MCG Failure Information is sent and stops after receiving the base station's response message. If T316 times out, the radio link reestablishment procedure is initiated.

[0148] For a single-hop relay network, the initial value of T319 of the L2 remote UE is configured by the remote UE-specific parameter t319-RemoteUE.

[0149] For item B4 above, the timer is used to prevent the UE from frequently sending User Equipment Assistance Information (UAI) messages containing release requests (also described as release preferences). The UE starts the timer after sending the UAI message containing the release request and stops it when it receives the release preference configuration (Config) or when the radio link is reestablished or resumed.

[0150] Regarding item B5 above: the timer is used to limit the UE in the RRC_CONNECTED state from frequently initiating dedicated system message requests (Dedicated SIB Request). After the UE sends a system message request, T350 is started. During the operation of T350, no dedicated system message request is initiated; after receiving the requested system message, T350 is stopped.

[0151] Item B6 above: The time range used to configure the completion of the RRC reconfiguration message (RRCReconfiguration) including the relay link switch (sl-PathSwitchConfig) starts when the remote UE receives the RRC reconfiguration message and stops when the target relay link is successfully established. In existing standards, this is reflected as stopping when the reconfiguration is complete (for example, when the RRC reconfiguration complete message RRCReconfigurationComplete is successfully sent via the target relay link). Its initial value is configured in SL-PathSwitchConfig.

[0152] The T420 timeout indicates that the UE will initiate the radio link reestablishment process after the link handover fails.

[0153] For item B7 above, the timer is used to manage the time range for completing the radio link resume procedure (RRC Resume). It starts after the UE sends a radio link resume request (RRC Resume Request / RRC ResumeRequest1) and stops after the UE receives the corresponding response message. If T319 times out, the UE falls back to the RRC_IDLE state.

[0154] The timer in the embodiment of the present application may also be other timers, for example, a timer used to manage the MCG failure information reporting process, which is not specifically limited in this application.

[0155] In an embodiment of the present 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. As a result, the purpose of determining the running duration of the timer based on the number of backhaul hops 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 timer operation due to the setting of an inappropriate timer running duration, thereby triggering unnecessary timer timeout behavior, thereby effectively reducing the number of link interruptions, reducing terminal power consumption, etc., and improving wireless connection management performance.

[0156] As shown in FIG7 , the embodiment of the present application further provides a method for processing timer information, including:

[0157] Step 701: The network-side device sends an initial value configuration parameter of a timer, where the initial value configuration parameter is related to the number of hops of a backhaul link in a relay network.

[0158] The network side device is a network side device in a relay network.

[0159] Optionally, the relay network is a multi-hop relay network.

[0160] In an embodiment of the present application, the initial value configuration parameters may be transmitted via a system message or an RRC message. For example, a relay UE within the signal coverage of a base station receives a system message containing the initial value configuration parameters from the base station and forwards the system message to downstream relay UEs and remote UEs. After a relay UE receives the system message from an upstream relay UE, it forwards the system message to downstream relay UEs and remote UEs.

[0161] In an embodiment 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 determines 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, 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 unnecessary timer timeout behavior is triggered due to the inappropriate setting of the timer running duration, which makes the remote terminal unable to complete the corresponding signaling transmission during the timer running period. This can effectively reduce the number of link interruptions, reduce terminal power consumption, etc., and improve wireless connection management performance.

[0162] Optionally, the initial value configuration parameter includes a first initial value, where the first initial value is the running duration of the timer when the link between the remote terminal and the network side device includes a one-hop Uu link or includes a one-hop Uu link and a one-hop PC5 link;

[0163] Alternatively, the initial value configuration parameter includes an association between the number of hops of the backhaul link and the initial value of the timer.

[0164] Optionally, the backhaul hop count of the backhaul link in the association relationship includes at least one of the following:

[0165] A first hop count, where the first hop count is a backhaul hop count of a backhaul link in the relay network;

[0166] A second hop count is a hop count associated with an initial value of the timer.

[0167] Optionally, the association relationship includes a correspondence between the number of hops of the backhaul link and the initial value of the timer;

[0168] Alternatively, the association relationship includes a correspondence between a hop count range of the backhaul link and an initial value of the timer.

[0169] This association relationship has been described in the method embodiment on the remote terminal side and will not be repeated here.

[0170] Optionally, the method of the embodiment of the present application further includes:

[0171] The network side device sends hop count information, where the hop count information is used by the remote terminal to determine a first hop count, where the first hop count is a backhaul hop count of a backhaul link in the relay network.

[0172] Here, the network side device sends the hop count information so that the remote terminal determines the second hop count related to the initial value of the timer according to the first hop count, and then determines the initial value of the timer based on the second hop count and the initial value configuration parameter.

[0173] As an implementation manner, the network side device sends the hop count information, including:

[0174] The network side device sends the hop count information through a system message or a Uu radio resource control RRC message.

[0175] Optionally, when the relay network includes at least two backhaul links, the first hop number or the second hop number is the first hop number or the second hop number 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;

[0176] Alternatively, in the case where the relay network includes at least two backhaul links, the first hop number or the second hop number is the first hop number or the second hop number corresponding to the second backhaul link, and the second backhaul link is the backhaul link with the largest first hop number or second hop number among the at least two backhaul links selected by the remote terminal in the relay network.

[0177] In an embodiment 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 determines 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, 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 unnecessary timer timeout behavior is triggered due to the inappropriate setting of the timer running duration, which makes the remote terminal unable to complete the corresponding signaling transmission during the timer running period. This can effectively reduce the number of link interruptions, reduce terminal power consumption, etc., and improve wireless connection management performance.

[0178] As shown in FIG8 , the embodiment of the present application further provides a method for processing timer information, including:

[0179] Step 801: The relay terminal sends hop count information, where the hop count information is used by 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.

[0180] Optionally, the relay terminal includes a host relay or an access relay.

[0181] 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 used to indicate the total hop count of the backhaul link between the network side device and the relay terminal, or used to indicate the hop count based on the PC5 connection in the backhaul link between the network side device and the relay terminal.

[0182] As an implementation manner, the relay terminal sends the hop count information, including:

[0183] The relay terminal sends the hop count information via a system message, a PC5RRC message, a discovery message, or a proximity service message.

[0184] For example, the host relay sends the hop count information via a proximity service message or a PC5RRC message, and the access relay sends the hop count information via a discovery message, a proximity service message or a PC5RRC message.

[0185] In an embodiment of the present application, a relay terminal sends hop count information, which is used by a remote terminal to determine a first hop count, where the first hop count is the backhaul hop count of a backhaul link in a relay network. This enables the remote terminal to determine an initial value of a timer based on an 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. This achieves the purpose of determining the running duration of the timer based on the backhaul hop count in the backhaul link, allowing the running duration of the timer to match the transmission time required for the signaling process corresponding to the timer in the relay network. This avoids or reduces the phenomenon in which an inappropriate timer running duration setting causes the remote terminal to be unable to complete corresponding signaling transmission during the timer running period, thereby triggering unnecessary timer timeouts. This effectively reduces the number of link interruptions, lowers terminal power consumption, and improves wireless connection management performance.

[0186] The timer information processing method provided in the embodiment of the present application can be executed by a timer information processing device. In the embodiment of the present application, the timer information processing device provided in the embodiment of the present application is described by taking the timer information processing method executed by the timer information processing device as an example.

[0249] Alternatively, in the case where the relay network includes at least two backhaul links, the first hop number or the second hop number is the first hop number or the second hop number corresponding to the second backhaul link, and the second backhaul link is the backhaul link with the largest first hop number or second hop number among the at least two backhaul links selected by the remote terminal in the relay network.

[0250] In an embodiment 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 determines 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, 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 unnecessary timer timeout behavior is triggered due to the inappropriate setting of the timer running duration, which makes the remote terminal unable to complete the corresponding signaling transmission during the timer running period. This can effectively reduce the number of link interruptions, reduce terminal power consumption, etc., and improve wireless connection management performance.

[0251] As shown in FIG11 , an embodiment of the present application provides a device 1100 for processing timer information, including:

[0252] The second sending module 1101 is configured to send hop count information, where the hop count information is used by a remote terminal to determine a first hop count, where the first hop count is a backhaul hop count of a backhaul link in a relay network.

[0253] Optionally, the second sending module sends the hop count information via a system message, a PC5RRC message, a discovery message or a proximity service message.

[0254] In an embodiment of the present application, a relay terminal sends hop count information, which is used by a remote terminal to determine a first hop count, where the first hop count is the backhaul hop count of a backhaul link in a relay network. This enables the remote terminal to determine an initial value of a timer based on an 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. This achieves the purpose of determining the running duration of the timer based on the backhaul hop count in the backhaul link, allowing the running duration of the timer to match the transmission time required for the signaling process corresponding to the timer in the relay network. This avoids or reduces the phenomenon in which an inappropriate timer running duration setting causes the remote terminal to be unable to complete corresponding signaling transmission during the timer running period, thereby triggering unnecessary timer timeouts. This effectively reduces the number of link interruptions, lowers terminal power consumption, and improves wireless connection management performance.
