Description

Uplink authorization processing method and related equipment

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to an uplink grant processing method and related devices.

Background

Long Term Evolution (LTE) is a Long Term Evolution of The Universal Mobile Telecommunications System (UMTS) technology standard established by The 3rd generation Partnership Project (3 GPP) organization. LTE significantly increases data transmission rates through Carrier Aggregation (CA) and Multiple Input Multiple Output (MIMO) technologies. In the LTE protocol of Release13, uplink and downlink data transmission capabilities of User Equipment (UE) are defined, and for example, the uplink data transmission rate of the UE supporting the uplink capability level 13 can reach 150 Mbit/s.

When the eNB sends the uplink Grant UL Grant to the UE in the nth subframe, the UE generally performs scheduling packet of uplink data from the (n + 1) th subframe after the nth subframe is released to the UL Grant issued by the eNB. However, because the UE also runs many application software when transmitting uplink data, the insufficient processing capability of the UE may cause the UE to process the UL Grant of the nth subframe only in the (n + 2) th subframe, which results in that the UE needs to process the UL Grant transmitted by the eNB in the (n + 1) th subframe and the (n + 2) th subframe at the same time. Taking a UE supporting uplink 2 Component Carrier (CC) Carrier Aggregation (CA) as an example, when uplink is transmitted with peak traffic, an eNB issues 2 UL grants to the UE on each subframe, so that the UE needs to process a total of 4 UL grants in the n +2 th subframe, and when planning the processing capability of the UE, the UE is usually set according to the UE capability supported by the UE, that is, for the UE supporting uplink 2CC CA, the uplink capability is usually 2 UL grants per subframe, which requires the UE to apply a certain algorithm to select two UL grants from the 4 UL grants and perform the subsequent group scheduling.

In the related existing scheme, for the UL Grant issued by the eNB in the nth subframe in the above scenario, when the UE processes the (n + 2) th subframe, a discarding scheme is usually adopted, that is, the UE directly discards the UL Grant issued by the eNB in the nth subframe, but when the (n + 1) th subframe is not fully scheduled (for example, the eNB issues only 1 UL Grant to the UE in the (n + 1) th subframe, and theoretically, the UE can process one UL Grant in the n subframe), the existing scheme of directly discarding the UL grants in all the nth subframes does not fully utilize the processing capability of the UE, thereby causing waste of uplink wireless resources and affecting uplink throughput and uplink throughput.

Disclosure of Invention

The invention provides an uplink authorization processing method and related equipment, which can improve the utilization rate of uplink wireless resources, improve uplink throughput and reduce time delay.

In a first aspect, an embodiment of the present invention provides an uplink grant processing method, including:

the terminal inquires a preset mapping relation set in the mth subframe or the s-th subframe, acquires x master cell group MCG uplink Grant UL Grants issued by a master evolution type base station MeNB corresponding to a subframe number m +2 in the m-2 subframe, and y auxiliary cell groups SCG UL Grant issued by the auxiliary evolution type base station SeNB corresponding to the subframe number s +2 in the s-2 sub-frame are obtained, wherein the preset mapping relationship set comprises a mapping relationship between the UL Grant which is not scheduled and the subframe number of the transmission subframe corresponding to the UL Grant which is not scheduled, the UL Grant processing capability of the terminal on each subframe is k, m, s, x and y are positive integers, the mth subframe and the s-th subframe correspond to the same signal processing time period of the terminal, k is an integral multiple of 2, and x and y are both less than or equal to k/2;

the terminal inquires the preset mapping relation set in the mth subframe, obtains p MCG UL Grants, corresponding to a subframe number m +3, of the MeNB at the m-1 subframe and obtains q SCG UL Grants, corresponding to a subframe number s +3, of the SeNB at the s-1 subframe, wherein p and q are positive integers, and both p and q are less than or equal to k/2;

and the terminal carries out scheduling processing on the x MCG UL Grants, the p MCG UL Grants, the y SCG UL Grants and the q SCG UL Grants according to the relation among x, y, p, q and k in the mth subframe.

As can be seen from the above, in the embodiment of the present invention, when a terminal queries a preset mapping relationship set in an mth subframe, acquires x MCG UL grants issued by an MeNB corresponding to a subframe number m +2 in an m-2 th subframe, acquires y SCG UL grants issued by an SeNB corresponding to the subframe number s +2 in an s-2 th subframe, acquires p MCG UL grants issued by an MeNB corresponding to the subframe number m +3 in an m-1 th subframe, and acquires q SCG UL grants issued by an SeNB corresponding to the subframe number s +3 in an s-1 th subframe, and determines that the acquired x MCG UL grants, y SCG UL grants, p MCG UL grants, and q SCG UL grants need to be processed simultaneously on the same subframe, the terminal may perform mapping on x g UL grants, y MCG UL grants, p, q, and k according to relationships between the x MCG UL grants, And carrying out scheduling processing on p MCG UL Grants, y SCG UL Grants and q SCG UL Grants. Since k is the UL Grant processing capability of the terminal in each subframe, that is, in the embodiment of the present invention, the terminal refers to the UL Grant processing capability of the terminal in each subframe, and fully utilizes the UL Grant processing capability of the terminal in each subframe, and reasonably schedules the x MCG UL grants, the p MCG UL grants, the y SCG UL grants, and the q SCG UL grants that need to be processed simultaneously in the same subframe, thereby avoiding the occurrence of the situation that the terminal has the capability of processing the UL Grant that is not processed in time but directly discards all the UL grants that are not processed in time, which is beneficial to improving the utilization rate of uplink radio resources, improving uplink throughput, and reducing time delay.

In one possible design, the terminal performs scheduling processing on the x MCG UL grants, the p MCG UL grants, the y SCG UL grants, and the q SCG UL grants in the mth subframe according to a relationship between x, y, p, q, and k, including:

if the terminal detects that x + p is equal to k in the mth subframe, the terminal discards the y SCG UL Grants and the q SCG UL Grants;

the terminal schedules the x MCG UL Grants in the mth subframe;

and the terminal schedules the p MCG UL Grants in the mth subframe.

It can be seen that, in this possible design, if the terminal detects that x + p is equal to k in the mth subframe, it may be determined that the UL Grant processing capability of the terminal on the same subframe can only satisfy processing of x MCG UL grants and p MCG UL grants, so that the terminal discards y SCG UL grants and q SCG UL grants first, then schedules x MCG UL grants that are not processed in time, and finally schedules p MCG UL grants.

if the terminal detects that x + p is less than k and k- (x + p) is less than or equal to q in the mth subframe, the terminal discards the y SCG UL Grants;

the terminal schedules the x MCG UL Grants in the mth subframe;

the terminal schedules the p MCG UL Grants in the mth subframe;

and the terminal schedules k- (x + p) SCG UL Grants in the q SCG UL Grants in the mth subframe.

It can be seen that, in this possible design, if the terminal detects that x + p is less than k and k- (x + p) is less than or equal to q in the mth subframe, it may be determined that the UL Grant processing capability of the terminal on the same subframe not only can satisfy processing of x MCG UL grants and p MCG UL grants, but also can satisfy processing of part or all of the SCG UL grants in q SCG UL grants, and therefore, the terminal discards y SCG UL grants first, schedules the x MCG UL grants first, schedules the p MCG UL grants again, and schedules k- (x + p) SCG UL grants in the q SCG UL grants finally, and thus, the terminal can ensure maximum utilization of the UL Grant processing capability of the current terminal, and is beneficial to improving the utilization rate of uplink wireless resources, improving the uplink throughput, and reducing the time delay.

if the terminal detects that x + p is smaller than k and k- (x + p) is larger than q in the mth subframe, the terminal schedules the x MCG UL Grants;

the terminal schedules k- (x + p) -q SCG UL Grants in the y SCG UL Grants in the mth subframe;

the terminal schedules the p MCG UL Grants in the mth subframe;

and the terminal schedules the q SCG UL Grants in the mth subframe.

It can be seen that, in this possible design, if the terminal detects that x + p is less than k and k- (x + p) is greater than q in the mth subframe, it may be determined that the UL Grant processing capability of the terminal on the same subframe can satisfy processing x MCG UL grants and p MCG UL grants, and satisfy processing k- (x + p) -q SCG UL grants in y SCG UL grants, and satisfy processing p MCG UL grants, and satisfy processing q SCG UL grants, so that the terminal schedules x MCG UL grants, then schedules k- (x + p) -q SCG UL grants in y SCG UL grants, and schedules p MCG UL grants and q SCG UL grants after preferentially scheduling the UL Grant for delayed processing, so that the terminal can ensure maximum utilization of the UL Grant processing capability of the current terminal, the method is beneficial to improving the utilization rate of uplink wireless resources, improving the uplink throughput and reducing the time delay.

Further, in one possible design, the terminal schedules the UL Grant, including:

the terminal analyzes the UL Grant and acquires information such as wireless channel resources, a coding modulation mode and the like used by the terminal for sending uplink data; the terminal calculates the size for sending uplink data according to the information such as the wireless channel resource, the coding modulation mode and the like; the terminal takes out the data with the size from the buffer and forms a data packet according to a format specified by a preset protocol; and the terminal transmits the data packet to an eNB (MeNB and/or SeNB) at the transmission time specified by a preset protocol.

Wherein the UL Grant includes any one UL Grant among the x MCG UL grants, the p MCG UL grants, the y SCG UL grants, and the q SCG UL grants.

In one possible design, before the terminal queries the preset mapping relationship set in the mth subframe or the sth subframe, the method further includes:

the terminal receives the x MCG UL grants issued by the MeNB and the y SCG UL grants issued by the SeNB at an m-2 th subframe, and stores a mapping relation between a subframe number m +2 and the x MCGUL grants and a mapping relation between a subframe number s +2 and the y SCG UL grants in the preset mapping relation set;

and the terminal receives the p MCG UL grants issued by the MeNB and the q SCG UL grants issued by the SeNB at an m-1 th subframe, and stores the mapping relation between a subframe number m +3 and the p MCGUL grants and the mapping relation between a subframe number s +3 and the q SCG UL grants in the preset mapping relation set.

In a second aspect, an embodiment of the present invention provides an uplink grant processing method, including:

a terminal inquires a preset mapping relation set in an nth subframe, and acquires i UL Grants which are issued by an evolved node B (eNB) corresponding to a subframe number n +2 in the nth-2 subframe, wherein the preset mapping relation set comprises a mapping relation between an UL Grant which is not scheduled and a subframe number of a sending subframe corresponding to the UL Grant which is not scheduled, the UL Grant processing capacity of the terminal on each subframe is k, i is a positive integer, and i is less than or equal to k;

the terminal inquires the preset mapping relation set in the nth subframe, and acquires j UL Grants which are issued by the eNB in the (n-1) th subframe and correspond to subframe numbers n +3, wherein j is a positive integer, and j is less than or equal to k;

and the terminal carries out scheduling processing on the i UL Grants and the j UL Grants according to the relation among i, j and k in the nth subframe.

As can be seen from the above, in the embodiment of the present invention, after the terminal queries the preset mapping relationship set in the nth subframe, acquires i UL grants issued by the eNB corresponding to the subframe number n +2 in the nth-2 subframe, and acquires j UL grants issued by the eNB corresponding to the subframe number n +3 in the nth-1 subframe, and when the terminal determines that the acquired i UL grants and the acquired j UL grants need to be processed simultaneously on the same subframe, the terminal may perform scheduling processing on the i UL grants and the j UL grants in the nth subframe according to the relationship between i, j, and k. Since k is the UL Grant processing capability of the terminal in each subframe, that is, in the embodiment of the present invention, the terminal reasonably schedules the i UL grants and the j UL grants that need to be processed simultaneously in the same subframe by referring to the UL Grant processing capability of the terminal in each subframe, thereby avoiding the occurrence of the situation that the terminal has the capability of processing the UL Grant that is not processed in time but directly discards all the UL grants that are not processed in time, which is beneficial to improving the utilization rate of uplink wireless resources, improving the uplink throughput, and reducing the time delay.

if the terminal detects that j is equal to k in the nth subframe, the terminal discards the i UL Grants;

It can be seen that, in this possible design, if the terminal detects that j is equal to k in the nth subframe, it may be determined that the UL Grant processing capability of the terminal on the same subframe can meet the requirement for processing j UL grants, and therefore the terminal discards i SCG UL grants first and then schedules j UL grants, so that the terminal may ensure that the UL Grant processing capability of the current terminal is maximally utilized, which is beneficial to improving the utilization rate of uplink wireless resources, improving uplink throughput, and reducing time delay.

if the terminal detects that j is smaller than k in the nth subframe, the terminal schedules k-i UL Grants in the i UL Grants;

and the terminal schedules the j UL Grants in the nth sub-.

It can be seen that, in this possible design, if the terminal detects that j is less than k in the nth subframe, it may be determined that the UL Grant processing capability of the terminal on the same subframe can satisfy processing of k-i UL grants in the i UL grants and processing of j UL grants, so that the terminal schedules k-i UL grants in the i UL grants first and then schedules j UL grants, and thus, the terminal may ensure that the UL Grant processing capability of the current terminal is maximally utilized, which is beneficial to improving the utilization rate of uplink wireless resources, improving uplink throughput, and reducing time delay.

the terminal analyzes the UL Grant and acquires information such as wireless channel resources, a coding modulation mode and the like used by the terminal for sending uplink data; the terminal calculates the size for sending uplink data according to the information such as the wireless channel resource, the coding modulation mode and the like; the terminal takes out the data with the size from the buffer and forms a data packet according to a format specified by a preset protocol; and the terminal transmits the data packet to the eNB at the transmission time specified by a preset protocol.

Wherein the UL Grant includes any one of the i UL Grants and the j UL Grants.

In one possible design, before the terminal queries the preset mapping relationship set in the nth subframe, the method further includes:

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

The network architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.

Some possible application scenarios and network architectures to which the embodiment of the present invention is applicable will be described below with reference to fig. 1A.

Fig. 1A illustrates a possible network architecture of an exemplary communication system provided by an embodiment of the present invention. The network architecture comprises network equipment, a terminal and core network equipment, wherein the terminal and the network equipment can be in communication connection through a wireless link. The exemplary communication system may be, for example, a Long Term Evolution (LTE) communication system, or a future communication system using a 5G New Air interface (NR) technology. Taking the LTE communication system as an example, the network device may be, for example, an LTE base station, that is, an Evolved Node B (eNode B), or a base station in a future 5G network, and is mainly responsible for at least one of functions of radio resource management, Quality of Service (QoS) management, data compression, encryption, and the like on the air interface side. The core network device may include, for example, a Mobility Management Entity (MME) or a Serving GateWay (S-GW), where the MME is mainly responsible for a signaling processing portion, i.e., a control plane function, including functions such as access control, mobility management, attach and detach, session management function, and GateWay selection. The S-GW is mainly responsible for user plane functions of user data forwarding, i.e. routing and forwarding of data packets under the control of the MME. And the eNode B is mainly responsible for forwarding the control plane signaling to the MME and forwarding the user plane service data to the S-GW towards the core network side.

In addition, the exemplary communication system supports a Dual Connectivity (DC) technology, where DC means that a terminal can provide wireless resources using two base stations in a connected state, and the two base stations can independently schedule the terminal, which is different from the Dual card Dual standby technology, which essentially means that two logical terminals access the two base stations respectively. In the DC, two base stations accessed by one terminal are divided into a Master evolved node b (Master E-UTRAN NodeB, MeNB) and a Secondary evolved node b (Secondary E-UTRAN NodeB, SeNB), a Group of cells provided by the MeNB is a Master Cell Group (MCG), and a Group of cells provided by the SeNB is a Secondary Cell Group (SCG). A typical DC scenario is shown in fig. 1B below. Under DC, the signaling bearer is only provided by the MeNB, i.e. the terminal only performs signaling interaction through the MCG and the MeNB.

In the embodiments of the present invention, the terms "network" and "system" are often used interchangeably, but those skilled in the art can understand the meaning. The terminal according to the embodiment of the present invention may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal), and the like. For convenience of description, the above-mentioned devices are collectively referred to as a terminal.

Currently, in the related art, taking an LTE communication system as an example, after a terminal establishes a connection with a base station, an uplink data transmission process of the terminal generally includes the following steps:

1. when the terminal has uplink data to send, if there is no uplink Grant (UL Grant) allocated by the base station at this time, reporting a Scheduling request (Scheduling Req, SR) to the base station for requesting the base station to allocate the UL Grant to the terminal;

2. after receiving the SR reported by the terminal, the base station allocates a corresponding UL Grant according to the number of the accessed terminals, the utilization condition of wireless resources, the quality of wireless channels and other conditions, and sends the UL Grant to the terminal;

3. after receiving the UL Grant allocated by the base station, the terminal analyzes the UL Grant to obtain information such as wireless channel resources which can be used by the terminal and coding modulation modes which can be used by the terminal, calculates the size which can be used for transmitting uplink data according to the information, extracts data with corresponding size from the buffer, forms a data packet according to a format specified by a protocol, and transmits the data packet to the base station at a transmission time specified by the protocol;

4. when the terminal sends uplink data to the base station, the terminal also needs to count the amount of uplink data to be sent in the Buffer, and periodically reports the amount of uplink data to the base station in the form of a Buffer Status Reporting (BSR), and when Reporting, the terminal sends the uplink data together;

5. when receiving an uplink data packet sent by a terminal, a base station analyzes the uplink data packet according to a format specified by a protocol, and when a BSR is analyzed, the base station acquires an uplink data buffer state of the terminal and allocates a new UL Grant according to the state and other conditions;

6. if the base station can successfully analyze the uplink data sent by the terminal, sending an Acknowledgement (ACK) and the UL Grant allocated in the previous step to the terminal, and if the uplink data sent by the terminal cannot be successfully analyzed, sending a Negative Acknowledgement (NACK) and the UL Grant allocated in the previous step to the terminal;

7. when the terminal analyzes the ACK or NACK sent by the base station, if the ACK or NACK is ACK, the terminal uses the UL Grant to group a new uplink data packet, and if the NACK is NACK, the terminal uses the UL Grant to retransmit the previous data packet and sends the data packet at the time specified by the protocol.

Taking an LTE-FDD (Frequency Division Duplex) communication system as an example, the above process is shown in fig. 1C, where a Transmission Time Interval (TTI) is 1ms, a base station is an eNB, a terminal is a UE, a Schedule UL Grant indicates an UL Grant for scheduling an nth subframe, and the UL Grant indicates uplink data. A Hybrid Automatic Repeat reQuest (HARQ) cycle Time (RTT) is defined as a minimum value of a Time interval between retransmitted uplink data and the same uplink data transmitted last Time.

In the process of sending uplink data of the terminal, because the terminal has processing delay due to running of more application programs, when the uplink Grant UL Grant to be newly received by the (n + 1) th subframe and the uplink Grant UL Grant to be scheduled, which is received by the nth subframe and is not processed in time, need to be processed simultaneously on the (n + 2) th subframe (the UL Grant received by the nth subframe should be scheduled and processed on the (n + 1) th subframe), a scheme of directly discarding the uplink Grant UL Grant to be scheduled and not processed in time is generally adopted, and when the UL Grant received by the terminal on the (n + 2) th subframe is not fully scheduled, the scheme of directly discarding the uplink Grant UL Grant to be scheduled and not processed in time obviously does not fully utilize the processing capability of the terminal, thereby causing waste of uplink wireless resources and affecting uplink throughput and delay.

In view of this, the embodiments of the present invention provide an uplink grant processing method, and a terminal based on the method. The method comprises the following steps: the terminal inquires a preset mapping relation set in a current subframe, acquires an UL Grant corresponding to a subframe number of a second subframe after the current subframe and acquires an UL Grant corresponding to a subframe number of a third subframe after the current subframe, determines that the UL Grant corresponding to the subframe number of the second subframe after the current subframe (also called non-timely processed UL Grant) and the UL Grant corresponding to the subframe number of the third subframe after the current subframe (also called newly received UL Grant) need to be processed at the same time in the current subframe, determines the UL Grant which can be processed by the terminal at most in the current subframe according to the number of the non-timely processed UL grants and the relationship between the number of the newly received UL grants and the UL Grant processing capability k of the terminal on each subframe, thereby discarding the part of the UL grants which cannot be processed when the non-processable UL grants exist, and scheduling the remaining UL Grant, or scheduling all UL grants when there is no unprocessed UL Grant, avoiding the occurrence of the situation that the UL Grant which is not processed in time is processed in a competent manner but all the UL grants which are not processed in time are directly discarded, which is beneficial to improving the utilization rate of uplink wireless resources, improving the uplink throughput, and reducing the time delay.

The embodiments of the present invention will be described in further detail below based on the common aspects related to the embodiments of the present invention described above.

The following describes the uplink grant processing method provided in the embodiment of the present invention with reference to fig. 2. Fig. 2 shows an uplink grant processing method provided in an embodiment of the present invention, where the method is applicable to a terminal supporting a DC technology. The method comprises the following steps: parts 201-203, specifically as follows:

in the 201 part, the terminal inquires a preset mapping relation set in the mth subframe or the s th subframe, acquires x master cell group MCG uplink Grant UL Grants issued by a master evolution base station MeNB corresponding to a subframe number m +2 in the m-2 th subframe, and y auxiliary cell groups SCG UL Grant issued by the auxiliary evolution type base station SeNB corresponding to the subframe number s +2 in the s-2 sub-frame are obtained, wherein the preset mapping relationship set comprises a mapping relationship between the UL Grant which is not scheduled and the subframe number of the transmission subframe corresponding to the UL Grant which is not scheduled, the UL Grant processing capacity of the terminal on each subframe is k, the mth subframe and the mth subframe correspond to the same signal processing time period of the terminal, m, s, x and y are positive integers, k is an integral multiple of 2, and x and y are both less than or equal to k/2.

Taking the MCG UL Grant sent by the MeNB received by the terminal in the m-2 th subframe as an example, if the terminal does not schedule the MCG UL Grant in the m-1 th subframe, the mapping relationship between the MCG UL Grant and the subframe number m +2 is continuously stored in the preset mapping relationship set (note that, if the terminal has scheduled the MCG UL Grant in the m-1 th subframe, the mapping relationship between the MCG UL Grant and the subframe number m +2 is not continuously stored in the preset mapping relationship set), after that, the terminal will schedule the MCG UL Grant in the m th subframe, and the MCG UL Grant is called an untimely UL Grant, and similarly, the SCG UL Grant sent by the SeNB received by the terminal in the s-2 th subframe is also not described herein again.

The m-2 subframe refers to a second subframe before the mth subframe, the m-1 subframe refers to a first subframe before the mth subframe, and for an example structure in which one radio frame includes 10 subframes with a subframe number of 0-9, if m is 0, the m-2 subframe specifically refers to an 8 th subframe in a previous radio frame of the current radio frame, and the m-1 subframe specifically refers to a 9 th subframe in a previous radio frame of the current radio frame, and so on, and the description is omitted here.

Further, it is noted that subframe numbers provided to the terminal by the MeNB and the SeNB in the same subframe period are different, but the length of each subframe of the MeNB and the SeNB is fixed to 1 ms. At the same moment, the MeNB subframe number acquired by the terminal is recorded as m, and the SeNB subframe number acquired is recorded as s, which is just like that when we look at the time of each place displayed in the weather forecast, at the same moment, beijing is 8 am, and new york is 8 pm. For a terminal supporting the DC technology, for the MeNB, similar descriptions such as "subframe number m + 2" are used, which means that the subframe number of the subframe after the current mth subframe plus 2 subframes corresponds to an uplink data transmission subframe (generally, 4 subframes delayed in sequence) corresponding to the UL Grant received by the terminal in the mth-2 subframe, and for the SeNB, similar descriptions such as "subframe number s + 2" are used. In the method, the terminal does not inquire whether the UL Grant corresponding to the subframe number m +1 and the subframe number s +1 is included in the preset mapping relation set in the mth subframe, because the subframe number m +1 is the (m + 1) th subframe used for sending uplink data, only 1 subframe is separated between the subframe and the mth subframe, and the 1 subframe is not enough for terminal read authorization, scheduling group packaging and uplink sending, so the consideration is not made.

In part 202, the terminal queries the preset mapping relation set in the mth subframe, obtains p MCG UL grants issued by the MeNB in the m-1 subframe and corresponding to a subframe number m +3, and obtains q SCG UL grants issued by the SeNB in the s-1 subframe and corresponding to a subframe number s +3, where p and q are positive integers, and both p and q are less than or equal to k/2.

At part 203, the terminal performs scheduling processing on the x mcgil grants, the p MCG UL grants, the y SCG UL grants, and the q SCG UL grants in the mth subframe according to a relationship between x, y, p, q, and k.

The terminal schedules the UL Grant, which specifically includes the following processing procedures: the terminal analyzes the UL Grant and acquires information such as wireless channel resources, a coding modulation mode and the like used by the terminal for sending uplink data; the terminal calculates the size for sending uplink data according to the information such as the wireless channel resource, the coding modulation mode and the like; the terminal takes out the data with the size from the buffer and forms a data packet according to a format specified by a preset protocol; and the terminal transmits the data packet to an eNB (MeNB and/or SeNB) at the transmission time specified by a preset protocol. Wherein the UL Grant includes any one UL Grant among the x MCGUL grants, the p MCG UL grants, the y SCG UL grants, and the q SCG UL grants.

It can be seen that, in the embodiment of the present invention, when the terminal queries the preset mapping relationship set in the mth subframe, obtains x MCG UL grants issued by the MeNB corresponding to the subframe number m +2 in the m-2 th subframe, obtains y SCG UL grants issued by the SeNB corresponding to the subframe number s +2 in the s-2 th subframe, obtains p MCG UL grants issued by the MeNB corresponding to the subframe number m +3 in the m-1 th subframe, and obtains q SCG UL grants issued by the SeNB corresponding to the subframe number s +3 in the s-1 th subframe, and determines that the obtained x MCG UL grants, y SCG UL grants, p MCG UL grants, and q SCG UL grants need to be processed simultaneously on the same subframe, the terminal may perform mapping on x g UL grants, y MCG UL grants, p, q, and k according to the relationship between the x MCG UL grants, y, p, q, and k in the mth subframe, And carrying out scheduling processing on p MCG UL Grants, y SCG UL Grants and q SCG UL Grants. Since k is the UL Grant processing capability of the terminal in each subframe, that is, in the embodiment of the present invention, the terminal refers to the UL Grant processing capability of the terminal in each subframe, and fully utilizes the UL Grant processing capability of the terminal in each subframe, and reasonably schedules the x MCG UL grants, the p MCG UL grants, the y SCG UL grants, and the q SCG UL grants that need to be processed simultaneously in the same subframe, thereby avoiding the occurrence of the situation that the terminal has the capability of processing the UL Grant that is not processed in time but directly discards all the UL grants that are not processed in time, which is beneficial to improving the utilization rate of uplink radio resources, improving uplink throughput, and reducing time delay.

In an example, according to the relationship between x, y, p, q, and k in the mth subframe, the specific implementation manner of the terminal performing scheduling processing on the x MCG UL grants, the p MCG UL grants, the y SCG UL grants, and the q SCG UL grants may be:

the terminal schedules the x MCG UL Grants in the mth subframe;

and the terminal schedules the p MCG UL Grants in the mth subframe.

It can be seen that, in this example, if the terminal detects that x + p is equal to k in the mth subframe, it may be determined that the UL Grant processing capability of the terminal on the same subframe only can satisfy processing of x MCG UL grants and p MCG UL grants, so that the terminal discards y SCG UL grants and q SCG UL grants first, then schedules x MCG UL grants that are not processed in time, and finally schedules p MCG UL grants.

the terminal schedules the x MCG UL Grants in the mth subframe;

the terminal schedules the p MCG UL Grants in the mth subframe;

It can be seen that, in this example, if the terminal detects that x + p is less than k and k- (x + p) is less than or equal to q in the mth subframe, it may be determined that the UL Grant processing capability of the terminal on the same subframe not only can satisfy processing of x MCG UL grants and p MCG UL grants, but also can satisfy processing of part or all of the SCG UL grants in q SCG UL grants, so that the terminal discards the y SCG UL grants first, schedules the x MCG UL grants first, schedules the p MCG UL grants again, and schedules k- (x + p) SCG UL grants in the q SCG UL grants finally, so that the terminal can ensure that the UL Grant processing capability of the current terminal is maximally utilized, which is beneficial to improving the utilization rate of uplink wireless resources, improving the uplink throughput, and reducing the time delay.

the terminal schedules the p MCG UL Grants in the mth subframe;

and the terminal schedules the q SCG UL Grants in the mth subframe.

It can be seen that, in this example, if the terminal detects that x + p is less than k and k- (x + p) is greater than q in the mth subframe, it may be determined that the UL Grant processing capability of the terminal on the same subframe can satisfy processing x MCG UL grants and p MCG UL grants, and satisfy processing k- (x + p) -q SCG UL grants in y SCG UL grants, satisfy processing p MCG UL grants, and satisfy processing q SCG UL grants, and therefore, the terminal schedules x MCG UL grants, then schedules k- (x + p) -q SCG UL grants in y SCG UL grants, and schedules p MCG UL grants and q SCG UL grants after preferentially scheduling the delayed UL Grant, so that the terminal can ensure maximum utilization of the UL Grant processing capability of the current terminal, the method is beneficial to improving the utilization rate of uplink wireless resources, improving the uplink throughput and reducing the time delay.

In an example, before the terminal queries the preset mapping relationship set at the mth subframe or the sth subframe, the method according to the embodiment of the present invention may further include:

It should be noted that, if the terminal does not delay processing the x MCG UL grants and the y SCG UL grants, that is, the terminal has scheduled x MCG UL grants and y SCG UL grants in the m-1 th subframe, the terminal deletes the mapping relationship between the subframe number m +2 and the x MCG UL grants stored in the preset mapping relationship set and the mapping relationship between the subframe number s +2 and the y SCG UL grants after scheduling the x MCG UL grants and the y SCG UL grants. That is, the life cycle of the mapping relationship between the subframe number and the UL Grant stored in the preset mapping relationship set is limited to the time when the terminal acquires the UL Grant until the terminal schedules the UL Grant.

The following describes the uplink grant processing method provided in the embodiment of the present invention with reference to fig. 3. Fig. 3 shows an uplink grant processing method provided in an embodiment of the present invention, where the method is applied to a terminal supporting a DC technology.

In the 303 part, the terminal inquires a preset mapping relation set in the mth subframe or the s subframe, acquires x master cell group MCG uplink Grant UL Grants issued by a master evolution base station MeNB corresponding to the subframe number m +2 in the m-2 subframe, and y auxiliary cell groups SCG UL Grant issued by the auxiliary evolution type base station SeNB corresponding to the subframe number s +2 in the s-2 sub-frame are obtained, the preset mapping relationship set comprises a mapping relationship between the UL Grant which is not scheduled and the subframe number of the sending subframe corresponding to the UL Grant which is not scheduled, the UL Grant processing capacity of the terminal on each subframe is k, the mth subframe and the mth subframe correspond to the same signal processing time period of the terminal, m, s, x and y are positive integers, k is an integral multiple of 2, and x and y are both less than or equal to k/2.

The following describes the uplink grant processing method provided in the embodiment of the present invention with reference to fig. 7. Fig. 3 shows an uplink grant processing method provided in an embodiment of the present invention, where the method is applicable to a terminal that does not support a DC technology. The method comprises the following steps: the parts 701-703 are as follows:

in part 701, a terminal queries a preset mapping relation set in an nth subframe, and acquires i UL grants issued by an evolved node b eNB corresponding to a subframe number n +2 in an nth-2 subframe, wherein the preset mapping relation set includes a mapping relation between an UL Grant which is not scheduled and a subframe number of a transmission subframe corresponding to the UL Grant which is not scheduled, a UL Grant processing capacity of the terminal on each subframe is k, i is a positive integer, and i is less than or equal to k.

Taking the UL Grant sent by the eNB and received by the terminal in the (n-2) th subframe as an example, if the terminal does not schedule the UL Grant in the (n-1) th subframe, the mapping relationship between the UL Grant and the subframe number n +2 is continuously stored in the preset mapping relationship set (note that, if the terminal has scheduled the UL Grant in the (n-1) th subframe, the mapping relationship between the UL Grant and the subframe number n +2 is not continuously stored in the preset mapping relationship set), and then the terminal will schedule the UL Grant in the (n) th subframe, and the UL Grant is called the UL Grant which is not processed in time.

The nth-2 subframe refers to a second subframe before the nth subframe, the nth-1 subframe refers to a first subframe before the nth subframe, and for example, in an exemplary structure in which one radio frame includes 10 subframes with subframe numbers of 0 to 9, if n is 0, the nth-2 subframe specifically refers to an 8 th subframe in a previous radio frame of the current radio frame, and the nth-1 subframe specifically refers to a 9 th subframe in a previous radio frame of the current radio frame, and so on, and will not be described herein again.

In addition, it should be noted that, for the eNB, similar descriptions such as "subframe number n + 2" are used, which means the subframe number of the subframe after the current nth subframe plus 2 subframes, where the subframe number corresponds to the uplink data transmission subframe (generally delayed by 4 subframes) corresponding to the UL Grant received by the terminal in the nth-2 subframe. In the method, the terminal does not inquire whether the UL Grant corresponding to the subframe number n +1 is included in the preset mapping relation set in the nth subframe, because the subframe number n +1 is the (n + 1) th subframe used for transmitting the uplink data, only 1 subframe is separated between the subframe and the nth subframe, and the 1 subframe is not enough for terminal read authorization, scheduling group package and uplink transmission, so the UL Grant corresponding to the subframe number n +1 is not considered.

In part 702, the terminal queries the preset mapping relationship set in the nth subframe, and acquires j UL grants issued by the eNB in the (n-1) th subframe corresponding to a subframe number n +3, where j is a positive integer and j is less than or equal to k.

At part 703, the terminal performs scheduling processing on the i UL grants and the j UL grants in the nth subframe according to the relationship between i, j, and k.

The terminal schedules the UL Grant, which specifically includes the following processing procedures: the terminal analyzes the UL Grant and acquires information such as wireless channel resources, a coding modulation mode and the like used by the terminal for sending uplink data; the terminal calculates the size for sending uplink data according to the information such as the wireless channel resource, the coding modulation mode and the like; the terminal takes out the data with the size from the buffer and forms a data packet according to a format specified by a preset protocol; and the terminal transmits the data packet to an eNB (MeNB and/or SeNB) at the transmission time specified by a preset protocol. Wherein the UL Grant includes any one of the i UL Grants and the j UL Grants.

It can be seen that, in the embodiment of the present invention, after the terminal queries the preset mapping relationship set in the nth subframe, acquires i UL grants issued by the eNB corresponding to the subframe number n +2 in the nth-2 subframe, and acquires j UL grants issued by the eNB corresponding to the subframe number n +3 in the nth-1 subframe, and when the terminal determines that the acquired i UL grants and the acquired j UL grants need to be processed simultaneously on the same subframe, the terminal may perform scheduling processing on the i UL grants and the j UL grants in the nth subframe according to the relationship between i, j, and k. Since k is the UL Grant processing capability of the terminal in each subframe, that is, in the embodiment of the present invention, the terminal reasonably schedules the i UL grants and the j UL grants that need to be processed simultaneously in the same subframe by referring to the UL Grant processing capability of the terminal in each subframe, thereby avoiding the occurrence of the situation that the terminal has the capability of processing the UL Grant that is not processed in time but directly discards all the UL grants that are not processed in time, which is beneficial to improving the utilization rate of uplink wireless resources, improving the uplink throughput, and reducing the time delay.

In an example, according to the relationship between i, j, and k in the nth subframe, the specific implementation manner of scheduling the i UL grants and the j UL grants by the terminal may be:

and the terminal schedules the j UL Grants in the nth subframe.

It can be seen that, in this example, if the terminal detects that j is equal to k in the nth subframe, it may be determined that the UL Grant processing capability of the terminal on the same subframe can meet the requirement for processing j UL grants, and therefore the terminal discards i SCG UL grants first and then schedules j UL grants, so that the terminal can ensure that the UL Grant processing capability of the current terminal is maximally utilized, which is beneficial to improving the utilization rate of uplink wireless resources, improving uplink throughput, and reducing time delay.

and the terminal schedules the j UL Grants in the nth subframe.

It can be seen that, in this example, if the terminal detects that j is less than k in the nth subframe, it may be determined that the UL Grant processing capability of the terminal on the same subframe can satisfy processing of k-i UL grants in the i UL grants and satisfy processing of j UL grants, so that the terminal schedules k-i UL grants in the i UL grants first and then schedules j UL grants, and thus, the terminal may ensure that the UL Grant processing capability of the current terminal is maximally utilized, which is beneficial to improving the utilization rate of uplink wireless resources, improving uplink throughput, and reducing time delay.

In an example, before the terminal queries the preset mapping relationship set in the nth subframe, the method of the embodiment of the present invention may further include:

It should be noted that, if the terminal does not delay processing the i UL grants, that is, the terminal has already scheduled i UL grants in the n-1 th subframe, the terminal deletes the mapping relationship between the subframe number n +2 stored in the preset mapping relationship set and the i UL grants after scheduling the i MCG UL grants is completed, that is, the life cycle of the mapping relationship between the subframe number stored in the preset mapping relationship set and the UL Grant is limited to the time when the terminal acquires the UL Grant until the terminal schedules the UL Grant.
