20240015574
This disclosure relates to the technical filed of communication processing, and in particular, to a method for triggering a buffer status report (BSR) by a relay and related products.
Dual connectivity (DC) technology is a technology for accelerating wireless communication transmission. In a DC architecture, a terminal is connected with two base stations and communicates with the two base stations at the same time. For a service, a logical channel, or data carried, the terminal can be configured to perform transmission through only base station 1, only base station 2, or base station 1 and base station 2 at the same time. When the data carried is configured to be transmitted through base station 1 and base station 2 at the same time, such bearer is referred to as a split bearer.
When the relay communicates with a network through DC, there is no implementation solution for how the relay triggers a buffer status report (BSR) and/or a pre-emptive BSR in a split bearer scenario, which affects a performance of the network.
In a first aspect, a method for triggering a BSR by a relay is provided. The relay is in a DC state, and the method includes the following. The relay determines whether a preset condition is satisfied according to a data volume of a certain service, based on that the relay determines that a bearer for the certain service is a split bearer. The relay determines a BSR triggering strategy for a protocol stack in the DC state according to whether the preset condition is satisfied.
In a second aspect, an electronic device is provided. The relay device includes a processor, a memory configured to store one or more programs, and a communication interface. The one or more programs are configured to be executed by the processor and include instructions configured to perform the method in the first aspect.
In a third aspect, a non-transitory computer-readable storage medium is provided. The computer-readable storage medium stores computer programs for electronic data interchange. The computer programs are operable with a computer to perform the method in the first aspect.
The following will introduce accompanying drawings required for describing implementations of the disclosure.
The following will illustrate implementations of the disclosure with reference to accompanying drawings of implementations of the disclosure.
The term “and/or” in the disclosure is simply an illustration of an association relationship of associated objects, indicating that three relationships can exist, for example, A and/or B, which can indicate the existence of A alone, A and B together, and B alone. In addition, the character “/” in the disclosure generally indicates that associated objects are in an “or” relationship.
In implementations of the disclosure, “multiple” or “a plurality of” refers to two or more. The descriptions such as first or second appearing in implementations of the disclosure are only for illustrative purposes and distinguishing the described objects, and are not in any order, nor do they indicate a particular limitation on the number of devices in implementations of the disclosure, and do not constitute any limitation on implementations of the disclosure. The term “connection” appearing in implementations of the disclosure refers to various connections, such as a direct connection or an indirect connection, to achieve communication between devices, which is not limited in implementations of the disclosure.
Technical solutions in implementations of the disclosure can be applicable to an exemplary communication system illustrated in
The exemplary communication system, for example, may be a global system of mobile communication (GSM), a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) system, a general packet radio service (GPRS) system, a long term evolution (LTE) system, an advanced LTE (LTE-A) system, a new radio (NR) system, an evolved system of the NR system, an LTE-based access to unlicensed spectrum (LTE-U) system, an NR-based access to unlicensed spectrum (NR-U) system, a universal mobile telecommunication system (UMTS), a next-generation communication system, or other communication systems.
Generally speaking, a conventional communication system supports a limited number of connections and therefore is easy to implement. However, with development of communication technology, a mobile communication system not only supports conventional communication but also supports, for example, device to device (D2D) communication, machine to machine (M2M) communication, machine type communication (MTC), and vehicle to vehicle (V2V) communication. Implementations herein can also be applicable to these communication systems. Optionally, a communication system in implementations of the disclosure can be applicable to a carrier aggregation (CA) scenario, a DC scenario, and a standalone (SA) scenario.
The terminal 110 in implementations of the disclosure may refer to a user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, a user device, etc. The terminal may also be a cellular radio telephone, a cordless telephone, a session initiation protocol (SIP) telephone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication functions, a computing device, other processing devices coupled with a wireless modem, a relay device, an in-vehicle device, a wearable device, or a terminal device in a further 5th-generation (5G) network, a terminal device in a future evolved public land mobile network (PLMN), etc., which is not limited in implementations of the disclosure.
The network devices 120 in implementations of the disclosure may be a device that is used to communicate with the terminal. The network device may be an evolved NodeB (eNB or eNodeB) in the LTE system, or a radio controller in a cloud radio access network (CRAN) scenario. Alternatively, the network device may also be a relay device, an access point (AP), an in-vehicle device, a wearable device, a network device in the future 5G network, a network device in the future evolved PLMN, or one antenna panel or one set of antenna panels (including multiple antenna panels) in a base station in the 5G system. Alternatively, the network device may also be a network node constructing a next generation NodeB (gNB) or a transmission point (TP), such as a baseband unit (BBU), a distributed unit (DU), or the like, which will not be limited herein.
In some deployments, the gNB may include a centralized unit (CU) and a DU. The gNB also may include an active antenna unit (AAU). The CU achieves a part of functions of the gNB, and the DU achieves a part of functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, to achieve functions of a radio resource control (RRC) layer and a packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical-layer protocols and real-time services, to achieve functions of a radio link control (RLC) layer, a medium access control (MAC) layer, and a physical (PHY) layer.
Referring to
During IAB discussion, an uplink (UL) resource for the terminal is allocated by the IAB node, an UL resource for the IAB node is allocated by the base station, and naturally the terminal needs to transmit a BSR to the IAB node to request a resource and the IAB node needs to transmit a BSR to the base station to request a resource. However, such a relay technology may cause a transmission delay. For example, the terminal transmits a BSR to the IAB node to request a resource when a data packet first arrives at the terminal, then the terminal transmits a specific data packet after the IAB node allocates resources, and the IAB node transmits a BSR to the base station to request a resource after the IAB node receives the specific data packet, resulting in an additional transmission delay.
To reduce extra transmission time, a pre-emptive BSR mechanism is introduced. The IAB node transmits a BSR to the base station once the IAB node receives a BSR from the terminal. That is, the IAB node informs the base station in advance that a data volume predicted by the IAB node needs to be transmitted although data has not been received, so that the base station can schedule resources in advance.
The pre-emptive BSR mechanism, although introduced in the IAB architecture, can be applied to all relay forwarding scenarios. As long as a transmission resource for a relay is allocated by a receiving end, the relay can trigger in advance a BSR to the receiving end to request a resource before receiving a specific data packet from a transmitting end, thereby reducing a transmission delay of data due to the introduction of the relay. However, in a relay DC network architecture as illustrated in
In the disclosure, the BSR may carry information indicating a data volume of existing data, and the pre-emptive BSR may carry information indicating a predicted data volume of data to-be-received. With the technical solution provided in the disclosure, in case of determining that the bearer for the certain service is the split bearer, it is determined whether the preset condition is satisfied according to the data volume of the certain service, and the BSR and/or pre-emptive BSR triggering strategy for the protocol stack in the DC state is determined, thereby implementing a BSR and/or pre-emptive BSR operation mechanism by the relay, and thus improving a network performance.
Referring to
S300, the relay determines whether a preset condition is satisfied according to a data volume of a certain service, on condition that the relay determines that a bearer for the certain service is a split bearer.
For definition of the split bearer, reference can be made to the above definition, which will not be repeated herein.
The certain service may be a service of a single UE or a service of multiple UEs.
S301, the relay determines a BSR triggering strategy for a protocol stack in the DC state according to whether the preset condition is satisfied.
With the technical solution provided in the disclosure, in case of determining that the bearer for the certain service is the split bearer, it is determined whether the preset condition is satisfied according to the data volume of the certain service, and the BSR triggering strategy for the protocol stack in the DC state is determined, thereby implementing a pre-emptive BSR operation mechanism by the relay, and thus improving a network performance.
In an optional solution, the above method may specifically include at least one of the following. If a predicted data volume of the certain service from a child node is greater than or equal to a first threshold, the relay determines that the preset condition is satisfied, and triggers a pre-emptive BSR in a first primary protocol layer and/or a first secondary protocol layer. If the data volume of the certain service is less than the first threshold, the relay determines that the preset condition is not satisfied, and triggers the pre-emptive BSR in only the first primary protocol layer. The first primary protocol layer is a first protocol layer associated with a primary base station, and the first secondary protocol layer is a first protocol layer associated with a secondary base station.
The first threshold may be a preset threshold.
The first primary protocol layer may specifically be a first protocol layer associated with the primary base station in the relay, and the first secondary protocol layer may be a first protocol layer associated with the secondary base station in the relay. The first protocol layer may specifically be an MAC layer.
In an optional solution, the above method may specifically include at least one of the following. The relay obtains a sum of an existing data volume of the certain service and a predicted data volume of the certain service from a child node. If the sum is greater than or equal to a second threshold, the relay determines that the preset condition is satisfied, and a second protocol layer of the relay indicates a data volume of the second protocol layer to a third primary protocol layer and a third secondary protocol layer. If the sum is greater than or equal to the second threshold, the relay determines that the preset condition is satisfied, and the second protocol layer of the relay indicates the data volume of the second protocol layer to a primary protocol stack and a secondary protocol stack. If the sum is less than the second threshold, the relay determines that the preset condition is not satisfied, and the second protocol layer of the relay indicates the data volume of the second protocol layer to the third primary protocol layer. If the sum is less than the second threshold, the relay determines that the preset condition is not satisfied, and the second protocol layer of the relay indicates the data volume of the second protocol layer to the primary protocol stack. If the third primary protocol layer of the relay receives a data-volume indication from the second protocol layer, a first primary protocol layer of the relay triggers the BSR. If the third secondary protocol layer of the relay receives the data-volume indication from the second protocol layer, a first secondary protocol layer of the relay triggers the BSR. If the primary protocol stack of the relay receives the data-volume indication from the second protocol layer, the first primary protocol layer of the relay triggers the BSR. If the secondary protocol stack of the relay receives the data-volume indication from the second protocol layer, the first secondary protocol layer of the relay triggers the BSR.
In an optional solution, the above method may specifically include at least one of the following. The relay obtains a sum of an existing data volume of the certain service and a predicted data volume of the certain service from a child node. If the sum is greater than or equal to a second threshold, the relay determines that the preset condition is satisfied, and a second protocol layer of the relay transmits an indication to a third secondary protocol layer. If the sum is greater than or equal to the second threshold, the relay determines that the preset condition is satisfied, and the second protocol layer of the relay transmits the indication to a secondary protocol stack. If the third secondary protocol layer of the relay receives a data-volume indication from the second protocol layer, a first secondary protocol layer of the relay triggers a pre-emptive BSR. If the secondary protocol stack of the relay receives the data-volume indication from the second protocol layer, the first secondary protocol layer of the relay triggers the pre-emptive BSR. The third primary protocol layer is a third protocol layer associated with a primary base station, the primary protocol stack is a protocol stack associated with the primary base station, the secondary protocol stack is a protocol stack associated with a secondary base station, and the third secondary protocol layer is a third protocol layer associated with the secondary base station.
The third protocol layer is an RLC layer, and the second protocol layer is a PDCP layer or a backhaul adaptation protocol (BAP) layer. It needs to be noted that, although the third primary protocol layer and the third secondary protocol layer have the same name, a device associated with the third primary protocol layer is different from that associated with the third secondary protocol layer, and hence the third primary protocol layer and the third secondary protocol layer are actually two protocol layers in the relay.
In an optional solution, the protocol stack is a preset protocol stack or a protocol stack determined by a network device.
A method for triggering a BSR by a relay is provided in an implementation of the disclosure. The method is implemented in the network architecture illustrated in
S400, the relay determines whether a predicted data volume of a certain service from a child node is greater than or equal to a first threshold.
Implementation methods for predicting the data volume of the certain service from the child node by the relay may specifically include the following. The data volume of the certain service can be predicted according to a content of a BSR received from the child node. In actual applications, the data volume of the certain service can be predicted according to a scheduling resource allocated to the child node.
S401, if the predicted data volume of the certain service from the child node is greater than or equal to the first threshold, the relay triggers a pre-emptive BSR in the first primary protocol layer and/or the first secondary protocol layer.
S402, if the predicted data volume of the certain service from the child node is less than the first threshold, the relay triggers the pre-emptive BSR in only the first primary protocol layer.
In implementations of the disclosure, the certain service may specifically be a certain logical channel, or a certain logical channel group in actual applications.
In this implementation of the disclosure, determination of whether the data volume of the certain service from the child node is greater than or equal to the first threshold is merely a necessary condition rather than a sufficient condition for triggering the pre-emptive BSR. Whether the pre-emptive BSR is really triggered at last needs to consider other conditions, for example, when a BSR from a child node is received, or when a transmission resource is to be allocated to the child node.
In the technical solution of this implementation, if a data volume to-be-received predicted by the relay exceeds a threshold, the relay triggers the pre-emptive BSR to the primary and secondary base stations on condition that other conditions for triggering the pre-emptive BSR are satisfied. Otherwise, the relay triggers the pre-emptive BSR to only the primary base station. In this implementation of the disclosure, a pre-emptive BSR operating mechanism is designed on condition that the relay communicates with the network through DC and transmits data to the network through the split bearer, thereby improving a network performance.
A method for triggering a BSR by a relay is provided in another implementation of the disclosure. The method is implemented in the network architecture illustrated in
S500, the relay determines whether a sum of an existing data volume of a certain service and a predicted data volume of the certain service from a child node is greater than or equal to a second threshold.
For implementation methods for predicting the data volume of the certain service from the child node by the relay, reference can be made to the specific description of the operations at S400, which will not be repeated herein.
The existing data volume may be a sum of a data volume of a second protocol layer and a data volume of a third protocol layer (including data to-be-initially-transmitted of the third primary protocol layer and data to-be-initially-transmitted of the third secondary protocol layer).
The second threshold may be the same as, greater than, or less than the first threshold in the above-mentioned implementations.
S501, if the relay determines that the sum is greater than or equal to the second threshold, the second protocol layer of the relay indicates the data volume of the second protocol layer to the third primary protocol layer (or a primary protocol stack) and the third secondary protocol layer (or a secondary protocol stack), and a first primary protocol layer and a first secondary protocol layer of the relay trigger the BSR.
S502, if the relay determines that the sum is less than the second threshold, the second protocol layer of the relay indicates the data volume of the second protocol layer to only the third primary protocol layer (or the primary protocol stack), and the first primary protocol layer of the relay triggers the BSR.
In implementations of the disclosure, the certain service may specifically be a certain logical channel, or a certain logical channel group in actual applications.
In the technical solution in this implementation, if the relay determines that the sum of the existing data volume of the certain service and the predicted data volume of the certain service from the child node exceeds the second threshold, the relay indicates data volume of the second protocol layer to the third primary protocol layer and the third secondary protocol layer, and then the first primary protocol layer and the first secondary protocol layer of the relay trigger the BSR. Otherwise, the relay indicates the data volume of the second protocol layer to the third primary protocol layer, and then only the first primary protocol layer triggers the BSR. In this implementation of the disclosure, a BSR operating mechanism is designed on condition that the relay communicates with the network through DC and transmits data to the network through the split bearer, thereby improving a network performance.
A method for triggering a BSR by a relay is provided in yet another implementation of the disclosure. The method is implemented in the network architecture illustrated in
S600, the relay determines whether a sum of an existing data volume of a certain service and a predicted data volume of the certain service from a child node is greater than or equal to a second threshold.
For implementation methods for predicting the data volume of the certain service from the child node by the relay, reference can be made to the specific description of the operations at S400, which will not be repeated herein.
The existing data volume may be a sum of a data volume of a second protocol layer and a data volume of a third protocol layer (including data to-be-initially-transmitted of the third primary protocol layer and data to-be-initially-transmitted of the third secondary protocol layer).
The second threshold may be the same as, greater than, or less than the first threshold in the above-mentioned implementations.
S601, if the relay determines that the sum is greater than or equal to the second threshold, the second protocol layer of the relay transmits an indication to the third secondary protocol layer (or a secondary protocol stack), and the first secondary protocol layer of the relay triggers a pre-emptive BSR.
In implementations of the disclosure, the certain service may specifically be a certain logical channel, or a certain logical channel group in actual applications.
In the technical solution in this implementation, if the relay determines that the sum of the existing data volume of the certain service and the predicted data volume of the certain service from the child node exceeds the second threshold, the relay transmits the indication to the third secondary protocol layer, and then the first secondary protocol layer of the relay triggers the pre-emptive BSR. Otherwise, only the first primary protocol layer of the relay triggers the pre-emptive BSR. In this implementation of the disclosure, a pre-emptive BSR operating mechanism is designed on condition that the relay communicates with the network through DC and transmits data to the network through the split bearer, thereby improving a network performance.
