Description

1 / 49 METHOD OF ALLOCATING RESOURCES, TERMINALS, APPARATUS AND TECHNICAL FIELD SYSTEMS

[001] The present invention relates to the field of communication technologies and, in particular, to a method of resource allocation and a terminal. BACKGROUND

[002] A radio interface technology (RIT) is generally referred to, in numerology, as Long Term Evolution technology. Evolution, LTE), and may include a form of multiple access, a modulation and coding scheme (MCS), a frame structure, a physical channel, a transport channel, a logical channel (LCH), medium access control (MAC), radio link control (RLC), packet data convergence protocol (PDCP), radio resource control (RRC), and the like.

[003] In an LTE system, because a terminal has a plurality of service requirements, an access network device configures a plurality of LCHs for the terminal. When the terminal needs to transmit data to the access network device, the access network device allocates a communication channel to the terminal. Therefore, when there is data to be transmitted across the plurality of LCHs, the data across the plurality of LCHs needs to be mapped onto the communication channel. Currently, a common method of resource allocation is: A priority is configured for each LCH; data on an LCH with high priority is first mapped onto the communication channel, until the communication channel is full or no data needs to be transmitted. However, in the previous method, because the LCH with high priority occupies... Petition 870240101308, dated 11 / 28 / 2024, page 12 / 87 2 / 49 is always the communication channel; a low-priority LCH has no resources to occupy, thus reducing the resource allocation balance. SUMMARY

[004] Embodiments of the present invention disclose a method of allocating resources and a terminal, to improve the balance of resource allocation.

[005] According to a first aspect, a resource allocation method is disclosed. The method is applied to a terminal and includes: receiving an uplink scheduling grant that is sent by an access network device and that includes a transport block corresponding to at least one radio interface technology, selecting a set of logical channels from the terminal's LCHs, and mapping, based on a prioritized bit rate (PBR) that is from each LCH in the set of logical channels and corresponding to a first radio interface technology, data to be sent corresponding to the set of logical channels in a transport block corresponding to the first radio interface technology, or in other words, sequentially mapping, based on a priority of each LCH in the set of logical channels,Some data that is in the data to be sent on each LCH and that meets a PBR corresponding to a first radio interface technology in a transport block corresponding to the first radio interface technology, instead of sequentially mapping, based on the priority of each LCH in the logical channel set, all the data to be sent on each LCH to the transport block corresponding to the first radio interface technology, so that a probability that data on a low-priority LCH will be transmitted can be increased, to improve the resource allocation balance. The channel set, Petition 870240101308, dated 11 / 28 / 2024, p. 13 / 87 3 / 49 logical is a set of LCHs in which there is data to be sent and which correspond to the first radio interface technology, and the first radio interface technology is any of at least one radio interface technology, or a radio interface technology specified by the access network device in at least one radio interface technology, or a radio interface technology having a top priority in at least one radio interface technology.

[006] In one embodiment, the set of logical channels may include a first subset of logical channels and a second subset of logical channels, a first radio interface technology of each LCH in the first subset of logical channels is the first radio interface technology, and a second radio interface technology of each LCH in the second subset of logical channels is the first radio interface technology.Because the priority of an LCH using the first radio interface technology as the primary radio interface technology is always higher than that of an LCH using the first radio interface technology as the secondary radio interface technology, data to be sent on each LCH in the first subset of logical channels can first be mapped, based on a priority and a PBR that are specific to each LCH and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology, in order to improve the resource allocation balance on the LCH using the first radio interface technology as the primary radio interface technology.

[007] In one embodiment, the uplink scheduling grant may also include a transport block capacity and transmission time. Petition 870240101308, dated 11 / 28 / 2024, p. 14 / 874 / 49 corresponding to at least one radio interface technology. When a first capacity is greater than a second capacity, after the data to be sent on each LCH in the first subset of logical channels is mapped, and based on priority and PBR, the remaining data to be sent on each LCH, where the remaining data to be sent in the first subset of logical channels can be mapped, based on a priority that is from each LCH and corresponding to the first radio interface technology, in the transport block corresponding to the first radio interface technology.Therefore, when the first capacity is greater than a third capacity, or in other words, when a transport block capacity corresponding to the first radio interface technology is greater than the sum of the data capacities to be sent on all LCHs in the first subset of logical channels, the data to be sent on each LCH in the second subset of logical channels can be mapped, based on a priority and a PBR that are specific to each LCH and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology, to ensure the utilization of radio resources while improving the resource allocation balance on the LCH using the first radio interface technology as the primary radio interface technology.The first capacity is the transport block capacity corresponding to the first radio interface technology; the second capacity is a product of the transmission time duration of the first radio interface technology and the sum of PBRs of all LCHs in the first subset of logical channels corresponding to the first radio interface technology; and the third capacity is the sum of the capacities of the data to be sent on all LCHs in the first subset of logical channels. Petition 870240101308, dated 11 / 28 / 2024, p. 15 / 87 5 / 49

[008] In one embodiment, the uplink programming allocation may further include the capacity and transmission time of the transport block corresponding to at least one radio interface technology. When the first capacity is greater than the second capacity, the data to be sent on each LCH in the second subset of logical channels may be mapped, based on the priority and PBR that are of each LCH and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology.When the first capacity is greater than the fourth capacity, the remaining data to be sent on each LCH, where the remaining data to be sent on the first subset of logical channels can be mapped, based on the priority of each LCH and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology, to ensure the utilization of radio resources while improving the resource allocation balance on the LCH using the first radio interface technology as the primary radio interface technology. The fourth capacity is the sum of the first product and the second capacity, and the first product is a product of the transmission time duration of the first radio interface technology and a sum of PBRs (Priority Radio Breaks) from all LCHs in the second subset of logical channels and corresponding to the first radio interface technology.

[009] In one embodiment, the uplink programming allocation may further include the capacity and transmission time of the transport block corresponding to at least one radio interface technology. When the first capacity is greater than the second capacity, the data to be sent on each LCH in a Petition 870240101308, dated 11 / 28 / 2024, p. 16 / 87 6 / 49 The first group of logical channels can be mapped, based on a priority and a PBR that are from each LCH and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology. Then, when the first capacity is greater than one-fifth capacity, the remaining data to be sent on each LCH in which the remaining data to be sent exists in the first subset of logical channels can be mapped, based on the priority that is from each LCH and corresponds to the first radio interface technology, to the transport block corresponding to the first radio interface technology.Therefore, when the first capacity is greater than one-sixth capacity, the data to be sent on each LCH in a second group of logical channels can be mapped, based on a priority and a PBR that are specific to each LCH and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology, to ensure the utilization of radio resources while improving the resource allocation balance on the LCH using the first radio interface technology as the primary radio interface technology. The first group of logical channels is a group of LCHs having a pre-set parameter in the second subset of logical channels, and the second group of logical channels is a group of LCHs, different from the LCHs included in the first group of logical channels, in the second subset of channels.The fifth capacity is a sum of the second capacity and a second product; the second product is a product of the transmission time duration of the first radio interface technology and a sum of PBRs (Price-Based Radios) that are from all LCHs (Long-Term Channels) in the first logical channel group and corresponding to the first radio interface technology; and the sixth capacity is a product of the transmission time duration of the first technology. Petition 870240101308, dated 11 / 28 / 2024, page 17 / 87 7 / 49 radio interface and the sum of the PBRs of all LCHs in the second subset of logical channels and corresponding to the first radio interface technology.

[0010] In one embodiment, when the first capability is greater than a seventh capability, or the first capability is greater than an eighth capability, the remaining data to be sent on each LCH where the remaining data to be sent exists in the second subset of logical channels can be mapped, based on a priority that is from each LCH and corresponding to the first radio interface technology, to the transport block corresponding to the radio interface technology, to further improve the utilization of radio resources. The seventh capability is the sum of the third capability and the first product, and the eighth capability is the sum of the third capability and the sixth capability.

[0011] In one embodiment, the set of logical channels may include a first subset of logical channels and a second subset of logical channels, a first radio interface technology of each LCH in the first subset of logical channels is the first radio interface technology, a second radio interface technology of each LCH in the first subset of logical channels is a second radio interface technology, a first radio interface technology of each LCH in the second subset of logical channels is the second radio interface technology, a second radio interface technology of each LCH in the second subset of logical channels is the first radio interface technology, and a transmission time interval (TTI) of the first radio interface technology is greater than a TTI of the second radio interface technology.The data to be sent on each LCH in the first subset of logical channels. Petition 870240101308, dated 11 / 28 / 2024, p. 18 / 87 8 / 49 can be mapped, based on a priority and a PBR that are from each LCH and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology. When the first data that was transmitted using the transport block corresponding to the first radio interface technology exists in the data to be sent corresponding to the second subset of logical channels, and a message that is sent by the access network device and that is used to indicate that the first data was successfully transmitted is not received, the first data can be mapped to a transport block corresponding to the second radio interface technology. This can increase a data transmission success rate with a relatively small TTI.

[0012] In one embodiment, the set of logical channels may include a first subset of logical channels and a second subset of logical channels, a radio interface technology of each LCH in the first subset of logical channels is the first radio interface technology, a second radio interface technology of each LCH in the first subset of logical channels is a second radio interface technology, a first radio interface technology of each LCH in the second subset of logical channels is the second radio interface technology, and a second radio interface technology of each LCH in the second subset of logical channels is the first radio interface technology.When a message sent by the access network device indicates that the second data in the second subset of logical channels is unsuccessfully transmitted in the transport block corresponding to the first radio interface technology, and is received before a transport block corresponding to the second radio interface technology is transmitted, the second data may... Petition 870240101308, dated 11 / 28 / 2024, p. 19 / 87 9 / 49 to be mapped to the transport block corresponding to the second radio interface technology, to ensure that data that needs to be retransmitted is transmitted using a low-latency feature, so that data retransmission efficiency can be improved.

[0013] According to a second aspect, a terminal is disclosed. The terminal includes units configured to execute the resource allocation method provided in the first aspect or any possible implementation of the first aspect.

[0014] According to a third aspect, a terminal is disclosed. The terminal includes a processor, a memory, and a transceiver, where the transceiver is configured to receive an uplink programming grant sent by an access network device, wherein the uplink programming grant includes a transport block corresponding to at least one radio interface technology; and the memory stores a set of program code, and the processor is configured to invoke the program code stored in memory to perform the following operations: Select a set of logical channels from the terminal's LCHs, where the set of logical channels is a set of LCHs on which data is to be sent and which correspond to a first radio interface technology, and the first radio interface technology is any one of at least one radio interface technology, or a radio interface technology specified by the access network device in at least one radio interface technology; and map, based on a priority and a PBR that are from each LCH in the set of logical channels and corresponding to the first radio interface technology, data to be sent. Petition 870240101308, dated 11 / 28 / 2024, p. 20 / 87 10 / 49 sent corresponding to the set of logical channels in a transport block corresponding to the first radio interface technology.

[0015] A fourth aspect describes a readable storage medium. The readable storage medium stores the program code used by a terminal to execute the resource allocation method provided in the first aspect or any possible implementation of the first aspect. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF THE METHODS OF IMPLEMENTATION

[0018] The following clearly and completely describes technical solutions in embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the embodiments described are only some and not all embodiments of the present invention. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without creative effort shall be within the scope of protection of the present invention.

[0019] The embodiments of the present invention disclose a method of resource allocation and a terminal for improving the balance of resource allocation. The resource allocation method and the terminal are described separately in detail. Petition 870240101308, dated 11 / 28 / 2024, page 22 / 87 12 / 49 below.

[0020] For a better understanding of the resource allocation method and the terminal disclosed in the embodiments of the present invention, the application scenarios and some concepts in the embodiments of the present invention are first described below. Common ways of multiple access include ways such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Code Division Multiple Access (CDMA), Orthogonal Frequency Division Multiple Access (OFDMA), and Single Carrier Frequency Division Multiple Access (SC-FDMA). A frame structure generally refers to a format and a corresponding parameter of data transmitted in a physical layer.Different wireless communication systems generally use specific frame structure designs for the wireless communication systems. For example, the frame structures of a 3rd Generation Partnership Project (3GPP) LTE system include a Type I frame structure used for Frequency Division Multiplexing (FDM) and a Type II frame structure used for Time Division Multiplexing (TDM). Both types of frame structures include 10 subframes each, each having a length of 1 ms. A key difference between the Type II frame structure and the Type I frame structure is that a special subframe is introduced in the Type II frame structure. The special subframe includes three special time slots: a downlink pilot time slot. Petition 870240101308, dated 11 / 28 / 2024, p. 23 / 87 13 / 49 The Type I frame structure consists of a Pilot TimeSlot (DwPTS), a Guard Period (GP), and an Uplink Pilot TimeSlot (UpPTS). DwPTS is always used for downlink transmission. UpPTS is always used for uplink transmission. GP is a guard interval for switching from downlink to uplink. Subframes in the Type I frame structure are classified into a downlink subframe and an uplink subframe based on different frequency bands, and both the downlink subframe and the uplink subframe can be used in any TTI. Subframes in the Type II frame structure are classified into an uplink subframe and a downlink subframe, and only the downlink subframe or the uplink subframe can be used in any TTI. A time period of a TTI is equal to a time period of a subframe.

[0021] On a carrier, the LTE system generally supports only one radio interface technology, for example, it supports only one way of multiple access, or it supports only one frame structure. The same radio interface technology on a carrier supports services with various Quality of Service (QoS), for example, it supports a Guaranteed Bit Rate (GBR) service and a Non-GBR service. The same radio interface technology used on the same carrier supports a Mobile Broadband (MBB) service and Machine-to-Machine (M2M) communication. Some optimized solutions can be used for M2M communication. For example, an Extended Access Barring (EAB) mechanism is introduced in the delay-tolerant M2M service, so that when a network is congested or Petition 870240101308, dated 11 / 28 / 2024, page 24 / 87 Due to network overload (14 / 49), some M2M terminals are temporarily prevented from accessing the network.

[0022] In the LTE system, an access network device configures at least one LCH for a terminal due to a plurality of service requirements. Each LCH corresponds to a Quality of Service (QoS) requirement of a service. For example, if the terminal needs an Internet access service and a Voice over LTE (VoLTE) service, two different LCHs are configured for the terminal to separately establish independent entities in a PDCP layer and an RLC layer for processing. A MAC layer is responsible for multiplexing a plurality of logical channels into a single transport channel. The terminal can only send one MAC protocol data unit (PDU) in each TTI of each carrier.

[0023] The uplink data transmission from the terminal is controlled by the access network device. A radio resource allocation mechanism is primarily as follows: The terminal can notify the access network device, using a Scheduling Request and a Buffer Status Report, that the terminal should send uplink data, in order to obtain an uplink scheduling grant and then initiate a Logical Channel Prioritization (LCP) process. The access network device sends the uplink scheduling grant to the corresponding terminal. The uplink scheduling grant is used to indicate a radio resource location to be used by the terminal, a modulation and encoding scheme, an amount of data to be transmitted, and the like.When the terminal receives a link programming grant. Petition 870240101308, dated 11 / 28 / 2024, page 25 / 87 15 / 49 ascending, indicating that the terminal needs to initiate a new uplink data transmission, the terminal needs to add RLC PDUs from a plurality of LCHs into the same MAC PDU. In this case, MAC multiplexing and LCP processing are required. Figure 1 is a schematic diagram of multiplexing a plurality of LCHs into a transport channel according to one embodiment of the present invention. As shown in Figure 1, a plurality of LCHs can be multiplexed into the same transport channel.

[0024] However, there is only one MAC PDU, but a plurality of LCHs needs to be multiplexed. Therefore, a priority is assigned to each LCH. Data in an LCH with the highest priority is first included in the MAC PDU, then data in an LCH with a second higher priority is included in the MAC PDU, and so on, until the MAC PDU is full or there is no more data to be sent. The priority of each LCH is determined in an RRC layer using a priority field of a LogicalChannelConfig of an Information Element (IE) in an RRC message, and a lower value indicates a higher priority. However, in this method of assignment, an LCH with a high priority can always occupy a radio resource allocated by an eNodeB to the terminal, and consequently, an LCH with a low priority has no resources to occupy.

[0025] To avoid the previous case, a PBR concept is introduced into the LTE system. To be specific, before resources are allocated to LCHs, the data rates of the LCHs are configured to ensure a minimum data rate for each LCH and to avoid a case where a low-priority LCH has no resources to occupy. The PBR is determined using a PBR field in the LCH configuration.

[0026] To support, on the same carrier, several Petition 870240101308, dated 11 / 28 / 2024, page 26 / 87 16 / 49 services that differ greatly in QoS requirements and / or radio condition requirements, it is proposed in a 5G system that an access network device and a terminal can use at least one radio interface technology in a continuous spectrum or a carrier plurality via FDM or TDM. For example, the terminal can support both a long TTI (1 ms) and a short TTI (0.2 ms). The long TTI is mainly used for a service with high bandwidth and high rate requirements. The short TTI can be used mainly for a service with a relatively strict latency requirement.

[0027] In the 5G system, an LCH can be flexibly mapped to at least one radio interface technology, at least one LCH can be located on the same carrier or different carriers, and coordinated operations are performed in a carrier aggregation (CA) or dual connectivity (DC). Because the access network device can determine a mapping relationship between an uplink / downlink LCH and a radio interface technology, a new challenge is posed for a related function, such as an LCP process, of an existing MAC layer. When an uplink scheduling grant received by the terminal indicates a new data transmission, the uplink scheduling grant may indicate a radio interface technology that needs to be used by the terminal to send data.When a Long-Half Connection (LHC) can be mapped to a plurality of radio interface technologies, an existing radio resource allocation technology cannot solve a radio resource allocation problem in such a scenario.

[0028] For a better understanding of the resource allocation method and the terminal disclosed in the embodiments of the present invention, a network architecture used in Petition 870240101308, dated 11 / 28 / 2024, page 27 / 87 One embodiment of the present invention is described below. Figure 2 is a schematic diagram of a network architecture according to one embodiment of the present invention. As shown in Figure 2, the network architecture may include at least one radio access network device 201 and a terminal 202. Terminal 202 is located within the coverage area of ​​at least one cell (carrier) provided by the radio access network device 201. When terminal 202 is located within the coverage area of ​​at least two cells (carriers) provided by the radio access device(s) 201, or in other words, when a plurality of cells serves terminal 202, terminal 202 may operate in an AC, DC, or coordinated multiple point transmission (CoMP) manner.At least one cell provides at least one radio interface technology, each of which provides a radio resource to terminal 202. Terminal 202 is configured to send a radio resource request to radio access network device 201. Access network device 201 is configured to send an uplink scheduling grant to terminal 202. Terminal 202 is further configured to transmit data to radio access network device 201 based on a radio resource allocated by access network device 201. Radio access network device 201 may be a base station, an evolved NodeB (eNB), an access point (AP), or similar. Terminal 202 may be a mobile terminal, such as a sensor having a network access function, or similar.The present invention is also applicable to a Universal Mobile Telecommunications System (UMTS), a CDMA system, a Wireless Local Area Network (WLAN), and a... Petition 870240101308, dated 11 / 28 / 2024, page 28 / 87 18 / 49 future 5G (fifth generation) wireless communications system, or similar.

[0029] Based on the network architecture shown in Figure 2, Figure 3 is a schematic flowchart of a resource allocation method according to one embodiment of the present invention. The resource allocation method shown in Figure 3 is described from the perspectives of the radio access network device 201 and the terminal 202. As shown in Figure 3, the resource allocation method may include the following steps.

[0030] 301. A terminal sends a radio resource request to a radio access network device.

[0031] In this embodiment, because the uplink data transmission is controlled by the access network device, when the terminal has data to be sent, the terminal sends the radio resource request to the radio access network device to request, from the access network device, a radio resource used to transmit uplink data.

[0032] 302. The radio access network device sends an uplink programming grant to the terminal.

[0033] In this embodiment, after receiving the radio resource request sent by the terminal, the radio access network device allocates a radio resource to the terminal, the allocated radio resource is sent to the terminal using the uplink scheduling grant. The radio resource may include a transport block corresponding to at least one radio interface technology. At least one radio interface technology is all or some radio interface technologies that can be provided by a cell in which the terminal is currently located. Petition 870240101308, dated 11 / 28 / 2024, page 29 / 87 19 / 49

[0034] 303. The terminal selects a set of logical channels from the terminal's logical channels.

[0035] In this embodiment, since the radio access network device configures more than one LCH for the terminal, and different LCHs may correspond to the same radio interface technology or different radio interface technologies, the data on all the terminal's LCHs can be transmitted using a transport block corresponding to a radio interface technology. Therefore, the terminal first needs to select the set of logical channels of the terminal's LCHs. The set of logical channels is the set of LCHs in which data to be sent exists and which correspond to a first radio interface technology, i.e., a set of LCHs in which the data to be sent exists and the data to be sent can be transmitted using a transport block corresponding to the first radio interface technology.The first radio interface technology can be any radio interface technology selected by the terminal from at least one radio interface technology, or it can be a radio interface technology specified by the access network device in at least one radio interface technology, or it can be a radio interface technology having the highest priority in at least one radio interface technology.

[0036] 304. The terminal maps, based on a priority and a PBR that are from each LCH in the set of logical channels and corresponding to a first radio interface technology, data to be sent corresponding to the set of logical channels in a transport block corresponding to the first radio interface technology.

[0037] In this embodiment, because the same LCH can have different priorities in different technologies of Petition 870240101308, dated 11 / 28 / 2024, p. 30 / 87 20 / 49 radio interface, after the terminal selects the set of logical channels of the terminal's LCHs, the terminal maps, based on the priority and PBR that are of each LCH in the set of logical channels and corresponding to the first radio interface technology, the data to be sent on each LCH in the set of logical channels in the transport block corresponding to the first radio interface technology.

[0038] For example, the access network device configures logical channels: an LCH 1, an LCH 2, an LCH 3, an LCH 4, an LCH 5, and an LCH 6 for the terminal. LCH 1, LCH 2, and LCH 3 can use the transport block corresponding to the first radio interface technology to transmit data, but they cannot use a transport block corresponding to a second radio interface technology to transmit data. LCH 4, LCH 5, and LCH 6 can use the transport block corresponding to the second radio interface technology to transmit data, but they cannot use the transport block corresponding to the first radio interface technology to transmit data. The priorities that belong to LCH 1, LCH 2, and LCH 3, and which correspond to the first radio interface technology, satisfy LCH 1 > LCH 2 > LCH 3. The priorities that belong to LCH 4, LCH 5, and LCH 6, and which correspond to the second radio interface technology, satisfy LCH 4 > LCH 5 > LCH 6.The terminal can map, based on the priorities that are from LCH 1, LCH 2, and LCH 3, and corresponds to the first radio interface technology and PBRs that are from LCH 1, LCH 2, and LCH 3 and corresponding to the first radio interface technology, data to be sent on LCH 1, LCH 2, and LCH 3 in the transport block corresponding to the first radio interface technology. For example, when a transmission time duration of the transport block corresponding to the first radio interface technology is T, and the PBRs that... Petition 870240101308, dated 11 / 28 / 2024, p. 31 / 87 21 / 49 are from LCH 1, LCH 2, and LCH 3, and which correspond to the first radio interface technology are respectively a PBR 1, a PBR 2, and a PBR 3. Some data having a PBR 1*T capacity in data to be sent on LCH 1 can first be mapped to the transport block corresponding to the first radio interface technology. Then, when the transport block corresponding to the first radio interface technology still has remaining capacity, some data having a PBR 2*T capacity in the data to be sent on LCH 2 is mapped to the transport block corresponding to the first radio interface technology. Then, when the transport block corresponding to the first radio interface technology still has remaining capacity, some data having a PBR 3*T capacity in the data to be sent on LCH 3 is mapped to the transport block corresponding to the first radio interface technology.

[0039] In this embodiment, the set of logical channels may include a first subset of logical channels and a second subset of logical channels, a first radio interface technology of the first subset of logical channels is the first radio interface technology, and a second radio interface technology of the second subset of logical channels is the first radio interface technology. Because a priority of an LCH corresponding to the first radio interface technology is always higher than a priority of an LCH corresponding to the second radio interface technology, the data to be sent on each LCH in the first subset of logical channels may first be mapped, based on a priority and a PBR that are from each LCH and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology. When the transport block corresponding to the first Petition 870240101308, dated 11 / 28 / 2024, p. 32 / 87 22 / 49 radio interface technology still has remaining capacity, the remaining data to be sent on each LCH in which the remaining data to be sent exists in the first subset of logical channels can be mapped, based on a priority that is from each LCH and corresponds to the first radio interface technology, to the transport block corresponding to the first radio interface technology, and when the transport block corresponding to the first radio interface technology still has remaining capacity, the data to be sent on each LCH in the second subset of logical channels is then mapped, based on a priority and a PBR that are from each LCH and correspond to the first radio interface technology, to the transport block corresponding to the first radio interface technology.Alternatively, the data to be sent on each LCH in the second subset of logical channels can be mapped, based on a priority and a PBR that are specific to each LCH and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology, and when the transport block corresponding to the first radio interface technology still has remaining capacity, the remaining data to be sent on each LCH in which the remaining data to be sent exists in the first subset of logical channels is then mapped, based on a priority that is specific to each LCH and that corresponds to the first radio interface technology, to the transport block corresponding to the radio interface technology.Alternatively, the data to be sent on each LCH in a first group of logical channels can be mapped, based on a priority and a PBR that are specific to each LCH and correspond to the first radio interface technology, to the transport block corresponding to the first radio interface technology. Petition 870240101308, dated 11 / 28 / 2024, p. 33 / 87 23 / 49 when the transport block corresponding to the first radio interface technology still has remaining capacity, the remaining data to be sent on each LCH in which the remaining data to be sent on the first subset of logical channels is then mapped, based on a priority that is from each LCH and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology, and when the transport block corresponding to the first radio interface technology still has remaining capacity, data to be sent on each LCH in a second group of logical channels is mapped, based on a priority and a PBR that are from the LCH and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology.Finally, when the transport block corresponding to the first radio interface technology still has remaining capacity, the data to be sent on each LCH where the remaining data exists in the second subset of logical channels is then mapped, based on a priority that is specific to each LCH and corresponds to the first radio interface technology, to the transport block corresponding to the first radio interface technology. The first group of logical channels is a group of LCHs that have a predefined parameter in the second subset of logical channels. The second group of logical channels is a group of LCHs, in addition to the LCHs included in the first group of logical channels, in the second subset of logical channels.

[0040] For example, the first subset of logical channels includes logical channels: an LCH 1, an LCH 2, and an LCH 3, and the second subset of logical channels includes logical channels: an LCH 4, an LCH 5, and an LCH 6. The terminal first maps the data on LCH 1, LCH 2, and LCH 3 to a resource of Petition 870240101308, dated 11 / 28 / 2024, page 34 / 87 24 / 49 uplink based on priorities LCH 1 > LCH 2 > LCH 3 and PBRs that are from LCH 1, LCH 2 and LCH 3 and corresponding to the first radio interface technology. When there is still a remaining uplink resource, the terminal can map the remaining data to be sent on LCH 1, LCH 2 and LCH 3 to the uplink resource based on priorities LCH 1 > LCH 2 > LCH 3. When there is still a remaining uplink resource, the terminal maps the data on LCH 4, LCH 5 and LCH 6 to the uplink resource based on priorities LCH 4 > LCH 5 > LCH 6 and PBRs that are from LCH 4, LCH 5 and LCH 6 and corresponding to the first radio interface technology. When an uplink resource remains, the terminal maps the remaining data to be sent on LCH 4, LCH 5, and LCH 6 to the uplink resource based on the priorities LCH 4 > LCH 5 > LCH 6.

[0041] For example, the first subset of logical channels includes logical channels: one LCH 1, one LCH 2, and one LCH 3, and the second subset of logical channels includes logical channels: one LCH 4, one LCH 5, and one LCH 6. The terminal first maps the data on LCH 1, LCH 2, and LCH 3 to an uplink resource based on the priorities LCH 1 > LCH 2 > LCH 3 and PBRs that are from LCH 1, LCH 2, and LCH 3 and corresponding to the first radio interface technology. When there is still a remaining uplink resource, the terminal can map data on LCH 4, LCH 5, and LCH 6 to the uplink resource based on the priorities LCH 4 > LCH 5 > LCH 6 and PBRs that are from LCH 4, LCH 5, and LCH 6 and corresponding to the first radio interface technology. When there is still a remaining uplink resource, the terminal maps the remaining data to be sent on LCH 1, LCH 2, and LCH 3 to the uplink resource based on the priorities LCH 1 > LCH 2 > LCH 3.When there is still a remaining uplink resource, the terminal maps the remaining data to be used. Petition 870240101308, dated 11 / 28 / 2024, page 35 / 87 25 / 49 sent on LCH 4, LCH 5, and LCH 6 to the uplink resource based on the priorities LCH 4 > LCH 5 > LCH 6.

[0042] For example, the first subset of logical channels includes logical channels: LCH 1, LCH 2, and LCH 3, and the second subset of logical channels includes logical channels: LCH 4, LCH 5, and LCH 6. The terminal first maps the data on LCH 1, LCH 2, and LCH 3 to an uplink resource based on the priorities LCH 1 > LCH 2 > LCH 3 and PBRs that are from LCH 1, LCH 2, and LCH 3 and corresponding to the first radio interface technology. When there is still a remaining uplink resource, the terminal can map data on LCH 4 having a pre-set parameter (or in other words, having a uniform high priority) to the uplink resource based on a PBR that is from LCH 4 and corresponding to the first radio interface technology. When an uplink resource remains, the terminal maps the remaining data to be sent on LCH 1, LCH 2, and LCH 3 to the uplink resource based on the priorities LCH 1 > LCH 2 > LCH 3.When an uplink resource remains, the terminal maps, based on the priorities of LCH 5 and LCH 6 corresponding to the first radio interface technology and PBRs of LCH 5 and LCH 6 corresponding to the first radio interface technology, data on LCH 5 and LCH 6 to the transport block corresponding to the first radio interface technology. When an uplink resource remains, the terminal maps the remaining data to be sent on LCH 4, LCH 5, and LCH 6 to the uplink resource based on the priorities LCH 4 > LCH 5 > LCH 6.

[0043] In this embodiment, the set of logical channels may include a first subset of logical channels and a second subset of logical channels, a first Petition 870240101308, dated 11 / 28 / 2024, p. 36 / 87 26 / 49 radio interface technology of each LCH in the first subset of logical channels is the first radio interface technology, a second radio interface technology of each LCH in the first subset of logical channels is a second radio interface technology, a first radio interface technology of each LCH in the second subset of logical channels is the second radio interface technology, a second radio interface technology of each LCH in the second subset of logical channels is the first radio interface technology, and a TTI of the first radio interface technology is greater than a TTI of the second radio interface technology or, in other words, data in an LCH corresponding to the second radio interface technology is latency-sensitive data.The data to be sent on each LCH in the first subset of logical channels can be transmitted, based on a priority and a PBR that are specific to each LCH and corresponding to the first radio interface technology, in the transport block corresponding to the first radio interface technology. When the first data that was transmitted using the transport block corresponding to the first radio interface technology exists in the data to be sent corresponding to the second subset of logical channels, and a message sent by the access network device indicating that the first data was transmitted unsuccessfully is not received, the first data can be mapped to a transport block corresponding to the second radio interface technology. The first data can be mapped according to a rule in the previous implementation.The data to be sent is either data that was not transmitted or data that needs to be retransmitted after a transmission failure is determined based on received ARQ feedback. Petition 870240101308, dated 11 / 28 / 2024, page 37 / 87 27 / 49

[0044] For example, the first subset of logical channels includes a logical channel LCH 1 and the second subset of logical channels includes a logical channel LCH 2. Figure 4 is a schematic diagram of a data mapping method according to an embodiment of the present invention. As shown in Figure 4, when an uplink programming grant received by the terminal indicates that the terminal has an uplink resource corresponding to the first radio interface technology at time T1, the data to be transmitted exists on both LCH 1 and LCH 2. The terminal can map LCH 1 data to LCH 1 and LCH 2_1 data to LCH 2 to the uplink resource corresponding to the first radio interface technology at time T1 in a mapping method disclosed in the prior embodiment. In the figure, a horizontal line segment represents the LCH 1 data at LCH 1, and a vertical line segment represents the LCH 2_1 data at LCH 2.When the uplink scheduling grant received by the terminal indicates that the terminal has an uplink resource corresponding to the second radio interface technology at time T2, if a message is sent by the access network device and is used to indicate that the successfully transmitted LCH 2_1 data was not received at time T2, the LCH 2_1 data can be mapped, at time T2, to the transport block corresponding to the second radio interface technology.

[0045] It should be noted that, in an LTE or similar communications system, LCH 1 data, LCH 2_1 data, and LCH 2_2 data can be PDCP DDUs obtained after processing in a PDCP layer. The behavior of the terminal mapping of LCH2_1 data into different transport blocks can be considered as a process of performing segmentation and concatenation into a corresponding PDCP PDU to obtain different RLC PDUs. For another communications system Petition 870240101308, dated 11 / 28 / 2024, page 38 / 87 28 / 49 including a future communications system, the LCH 1 data, the LCH 2_1 data, and the LCH 2_2 data are data before segmentation and concatenation. When a buffer size is calculated to send a buffer status report (BSR), a size of the LCH 2_1 data that has been transmitted is recalculated in the BSR.

[0046] For example, the first subset of logical channels includes a logical channel LCH 1, and the second subset of logical channels includes a logical channel LCH 2. Figure 5 is a schematic diagram of another form of data mapping according to an embodiment of the present invention. As shown in Figure 5, when an uplink programming grant received by the terminal indicates that the terminal has an uplink resource corresponding to the first radio interface technology at time T1, data to be transmitted exists on both LCH 1 and LCH 2. The terminal can map LCH_1 data on LCH 1 and LCH 2 data on LCH 2 to an uplink resource corresponding to the second radio interface technology at time T1 in a mapping manner disclosed in the prior embodiment.When the uplink scheduling grant received by the terminal indicates that the terminal has an uplink resource corresponding to the first radio interface technology at time T2, the LCH1_1 data does not need to be mapped, at time T2, to the transport block corresponding to the first radio interface technology. LCH 1 is for a latency-insensitive service. Before a message used to indicate whether the LCH 1_1 data has been successfully or unsuccessfully transmitted is received, the LCH 1_1 data is processed as data that has been transmitted.

[0047] In this embodiment, the set of logical channels may include a first subset of logical channels Petition 870240101308, dated 11 / 28 / 2024, p. 39 / 87 29 / 49 and a second subset of logical channels, a first radio interface technology of each LCH in the first subset of logical channels is the first radio interface technology, a second radio interface technology of each LCH in the first subset of logical channels is a second radio interface technology, a first radio interface technology of each LCH in the second subset of logical channels is the second radio interface technology, and a second radio interface technology of each LCH in the second subset of logical channels is the first radio interface technology.When a message sent by the access network device indicates that the second data in the second subset of logical channels is unsuccessfully transmitted in the transport block corresponding to the first radio interface technology, and is received before a transport block corresponding to the second radio interface technology is transmitted, the second data is mapped to the transport block corresponding to the second radio interface technology.

[0048] For example, the first subset of logical channels includes a logical channel LCH 1, and the second subset of logical channels includes a logical channel LCH 2. Figure 6 is a schematic diagram of yet another form of data mapping according to an embodiment of the present invention. As shown in Figure 6, when an uplink programming grant received by the terminal indicates that the terminal has an uplink resource corresponding to the first radio interface technology at time T1, the data to be transmitted exists on both LCH 1 and LCH 2. The terminal can map LCH_1 data on LCH 1 and LCH 2 data on LCH 2 to an uplink resource corresponding to the second radio interface technology at time T1 in a mapping manner disclosed in the form of Petition 870240101308, dated 11 / 28 / 2024, p. 40 / 87 30 / 49 previous realization. Before the uplink scheduling grant received by the terminal indicates that the terminal has an uplink resource corresponding to the first radio interface technology at time T2, a message is received indicating that the LCH 1_1 data is transmitted unsuccessfully. Therefore, the LCH 1_1 data needs to be mapped, at time T2, to the transport block corresponding to the first radio interface technology. LCH 1_2 data is data to be sent to LCH 1.

[0049] It should be noted that, in an LTE or similar communications system, LCH 1_1 data, LCH 1_2 data, and LCH 2 data can be PDCP DDUs obtained after processing in a PDCP layer. The behavior of the terminal mapping of LCH1_1 data into different transport blocks can be considered as a process of performing segmentation and concatenation into a corresponding PDCP PDU to obtain different RLC PDUs. For other communications systems, including future communications systems, LCH 1_1 data, LCH 1_2 data, and LCH 2 data are data before segmentation and concatenation. When a buffer size is calculated to send a buffer status report (Buffer The Status Report (BSR) recalculates the size of the LCH 1_1 data that was transmitted.

[0050] 305. The terminal sends the mapped data to the access network device using the transport block corresponding to the first radio interface technology.

[0051] In the resource allocation method shown in Figure 3, the uplink scheduling grant sent by the access network device is received, where the uplink scheduling grant includes the transport block corresponding to at least one radio interface technology; the set of logical channels is selected from the terminal's logical channels; and the data to be Petition 870240101308, dated 11 / 28 / 2024, p. 41 / 87 31 / 49 of the data sent corresponding to the set of logical channels are mapped, based on the priority and prioritized bit rate of each logical channel in the set of logical channels and corresponding to the first radio interface technology, to the transport block corresponding to the first radio interface technology, instead of sequentially mapping, based on the priority of each logical channel in the set of logical channels, all the data to be sent in each logical channel to the transport block corresponding to the first radio interface technology, so that a probability that data in a logical channel with low priority will be transmitted can be increased, to improve the balance of resource allocation.

[0052] Based on the network architecture shown in Figure 2, Figure 7 is a schematic structural diagram of a terminal according to one embodiment of the present invention. As shown in Figure 7, the terminal may include: a 701 receiving unit, configured to receive an uplink programming grant sent by an access network device, wherein the uplink programming grant may include a transport block corresponding to at least one radio interface technology; a selection unit 702, configured to select a set of logical channels from the terminal's LCHs, wherein the set of logical channels is a set of LCHs on which data is sent and which correspond to a first radio interface technology received by the receiving unit 701, and the first radio interface technology may be any of at least one radio interface technology, or a radio interface technology specified by the access network device in at least one radio interface technology; and Petition 870240101308, dated 11 / 28 / 2024, p. 42 / 87 32 / 49 a 703 mapping unit, configured to map, based on a priority and a PBR that are from each LCH in the set of logical channels and corresponding to the first radio interface technology, data to be sent corresponding to the set of logical channels in a transport block corresponding to the first radio interface technology, where the set of logical channels is selected by the 702 selection unit.

[0059] The terminal shown in Figure 8 receives the uplink programming grant sent by the access network device, wherein the uplink programming grant includes the transport block corresponding to at least one radio interface technology; selects the set of logical channels from the terminal's logical channels;and maps, based on the prioritized priority and bit rate of each logical channel in the set of logical channels and corresponding to the first radio interface technology, the data to be sent corresponding to the set of logical channels in the transport block corresponding to the first radio interface technology, instead of sequentially mapping, based on a priority of each logical channel in the set of logical channels, all the data to be sent in each logical channel to the transport block corresponding to the first radio interface technology, so that a probability that the data in a logical channel with low priority will be transmitted can be increased, to improve the balance of resource allocation.
