Description

[0001] This application claims the priority of the PCT patent application titled "Method for Generating Data and Terminal Device" with the application number PCT / CN2017 / 103763 filed with the Chinese Patent Office on September 27, 2017, and the priority of the PCT patent application titled "Method for Generating Data and Terminal Device" with the application number PCT / CN2018 / 082046 filed with the Chinese Patent Office on April 4, 2018. The entire content of which is incorporated herein by reference. Technical Field

[0002] Embodiments of the present invention relate to the field of communications, and more particularly, to a method for generating data, a method for configuring a logical channel, a terminal device, and a chip. Background Art

[0003] The vehicle-to-everything (V2X) system is a sidelink (SL) transmission technology based on Long Term Evolution Vehicle-to-Vehicle (LTE D2D). Different from the way of receiving or sending communication data through a base station in a traditional LTE system, the V2X system adopts a direct terminal-to-terminal communication method. Therefore, it has higher spectral efficiency and lower transmission delay.

[0004] In the 3rd Generation Partnership Project (3GPP) Rel-14, the vehicle-to-everything (V2X) technology in the vehicle networking technology was standardized, and two transmission modes were defined: Mode 3 and Mode 4. Specifically, in Mode 3, as Figure 1 shown, the transmission resources of the vehicle-mounted terminals (vehicle-mounted terminal 121 and vehicle-mounted terminal 122) are allocated by the base station 110, and the vehicle-mounted terminals send data on the sidelink according to the resources allocated by the base station 110; the base station 110 can allocate resources for single transmission to the terminal or allocate semi-static transmission resources to the terminal. In Mode 4, as Figure 2 shown, the vehicle-mounted terminals (vehicle-mounted terminal 131 and vehicle-mounted terminal 132) adopt a transmission method of sensing plus reservation. Specifically, the terminal autonomously selects transmission resources on the resources of the sidelink to generate data.

[0005] However, with the evolution of the mobile Internet of Things technology (e.g., Rel.15), the enhanced vehicle-to-everything (eV2X) has been extended to multi-carrier scenarios, that is, a terminal device can simultaneously transmit and receive on more than one carrier.

[0006] Therefore, an urgent problem to be solved is how to perform carrier selection. Summary of the Invention

[0124] With the evolution of the mobile Internet of Things technology, eV2X has been extended to multi-carrier scenarios, that is, a terminal device can simultaneously transmit and receive on more than one carrier. Therefore, an urgent problem to be solved is how to perform carrier selection. Thus, an embodiment of the present invention proposes a method for generating data, enabling the terminal device to effectively select a carrier for generating data from multiple carriers based on data priorities.

[0125] Next, the technical solutions in the embodiments of the present invention will be described with reference to the accompanying drawings.

[0126] The embodiments of the present invention can be applied to any communication framework from terminal device to terminal device. For example, vehicle to vehicle (V2V), vehicle to everything (V2X), device to device (D2D), etc. That is to say, Figure 1 or Figure 2 the system framework of the in-vehicle terminal to in-vehicle terminal shown is only an example of the embodiments of the present invention, and the embodiments of the present invention are not limited thereto.

[0127] Among them, the terminal device in the embodiments of the present invention can be any device or apparatus configured with a physical layer and a media access control layer, and the terminal device can also be referred to as an access terminal. For example, a user equipment (UE), a user unit, a user station, a mobile station, a mobile device, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The access terminal can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device, or other linear processing devices connected to a wireless modem, a vehicle-mounted device, a wearable device, and so on. The embodiments of the present invention are described by taking a vehicle-mounted terminal as an example, but are not limited thereto.

[0128] The method for the terminal device in the embodiments of the present invention to obtain transmission resources is introduced below.

[0129] Figure 3 It is a schematic flowchart of the method for the terminal device in the embodiments of the present invention to listen to a resource pool.

[0130] As Figure 3 shown, it is assumed that each carrier corresponds to at least one sidelink process. For example, in 3GPP rel-14, one carrier corresponds to two sidelink processes. When a new data packet arrives at time n, the terminal device needs to select resources. The terminal will select resources within the interval [n + T1, n + T2] according to the listening results in the past period (for example, 1 s). Specifically, the terminal device can select resources in the selection window by detecting the channel quality information corresponding to the resources within the listening window.

[0131] Among them, T1 ≤ 4 ms; 20 ms ≤ T2 ≤ 100 ms.

[0132] In addition, the channel quality information corresponding to the resource may be the channel quality (e.g., received power or received quality) of the Physical Sidelink Shared Channel (PSSCH) corresponding to the Physical Sidelink Control Channel (PSCCH). The terminal device can also detect the Receive Signal Strength Indicator (RSSI) of the resources in the transmission resource set to obtain the channel quality information corresponding to each resource in the transmission resource set.

[0133] It should be noted that the value ranges of T1 and T2 are only taken as an example and should not limit this embodiment.

[0134] Since the services in the vehicle-to-everything (V2X) system have periodic characteristics. Therefore, in the embodiments of the present invention, the terminal device can adopt a semi-static transmission mode.

[0135] Specifically, when the terminal device selects a resource for transmission, the terminal device will continuously use and reserve this resource Cresel times. Each time data is transmitted, Cresel is decremented by 1. When Cresel is decremented to 0, the terminal will randomly generate a random number between [0, 1] and compare it with the parameter (probResourceKeep). If it is greater than the parameter, the terminal performs resource reselection. If it is less than the parameter, the terminal continues to use this resource and resets Cresel.

[0136] That is, the terminal device will carry the information of reserving the next transmission resource in the control information of this transmission, so that other terminal devices can determine whether this resource is reserved and used by this terminal device by detecting the control information of this terminal device, achieving the purpose of reducing resource conflicts. In other words, after selecting a transmission resource, the terminal device in the embodiments of the present invention can continuously use this resource in multiple transmission cycles, thereby reducing the probability of resource reselection and resource conflicts.

[0137] It should be understood that Figure 3 The method for the terminal device to listen to the resource pool shown is an exemplary description of how the terminal device obtains resources, and the embodiments of the present invention do not make specific limitations. For example, the network device can also allocate transmission resources for the terminal device.

[0138] Next, the method for generating data in the embodiments of the present invention will be introduced.

[0139] Figure 4 is a schematic flowchart of the method for generating data in the embodiments of the present invention.

[0140] AsFigure 4 As shown, the method includes:

[0141] 210. Receive Radio Link Control (RLC) data on n logical channels.

[0142] 220. Determine k logical channels among the n logical channels according to the priorities of the n logical channels and the priority associated with the first carrier among the multiple carriers of the terminal device.

[0143] 230. Generate a Media Access Control (MAC) protocol data unit (PDU), where the MAC PDU includes the RLC PDUs on the k logical channels.

[0144] Specifically, the terminal device receives RLC data on n logical channels, where the n logical channels belong to the m logical channels, m ≥ n > 0; determines k logical channels among the n logical channels according to the priorities of the n logical channels and the priority associated with the first carrier among the multiple carriers, n ≥ k > 0; and generates a MAC protocol data unit PDU, where the MAC PDU includes the RLC PDUs on the k logical channels.

[0145] In short, the terminal device selects k logical channels from the n logical channels and generates a MAC PDU to be transmitted on the first carrier based on the k logical channels.

[0146] It should be noted that since the MAC PDU packet assembly rule is related to the priority of the data.

[0147] Therefore, there is a prerequisite for the method of generating data in the embodiments of the present invention, that is, the terminal device is configured with m logical channels and multiple carriers, each of the m logical channels is configured with a priority, and each of the multiple carriers is associated with the priority of at least one of the m logical channels, m > 0.

[0148] Thus, when the terminal device receives RLC data on n logical channels, it can select k logical channels from the n logical channels according to the priorities of the n logical channels and the priority associated with the first carrier among the multiple carriers of the terminal device, and then generate a MAC PDU to be transmitted on the first carrier.

[0149] Those skilled in the art can understand that the data that enters each sublayer without being processed is called a service data unit (SDU), and the data formed after being processed by the sublayer and having a specific format is called a protocol data unit (PDU).

[0150] That is to say, the PDU formed by this layer is the SDU of the next layer.

[0151] For example, each logical channel of a terminal device has an RLC entity. The data received by the RLC entity from the MAC layer or sent to the MAC layer can be called an RLC PDU (or a MAC SDU).

[0152] The following introduces the implementation manner for the terminal device to determine the k logical channels among the n logical channels in the embodiments of the present invention.

[0153] Optionally, as an embodiment, the terminal device can determine the k logical channels among the n logical channels, and the priority of each logical channel among the k logical channels belongs to the priority associated with the first carrier.

[0154] Specifically, when generating a MAC PDU, the terminal device can determine the k logical channels among the n logical channels, and the priority of each logical channel among the k logical channels belongs to the priority associated with the first carrier, and then generate a MAC PDU transmitted on the first carrier based on the k logical channels.

[0155] It should be noted that in the prior art, the terminal device generates a MAC PDU according to certain principles. For example, when the priority of the RLC SDU in the MAC PDU includes X, assuming that the priority of X is higher than that of Y, the priority of Y is higher than that of Z, and both Y and Z are the priorities of the logical channels that the terminal device has, the MAC PDU will also include the RLC SDUs with priorities of Y and Z.

[0156] Therefore, in order to improve the compatibility and application scope of the method for generating data in the embodiments of the present invention with the prior art. In the embodiments of the present invention, the priority associated with each carrier among the multiple carriers that the terminal device has can be designed by referring to the packet assembly rules of the MAC PDU in the prior art. In this way, the current process of generating the MAC PDU can be kept unchanged, and thus the compatibility between the embodiments of the present invention and the prior art can be maximally improved.

[0157] As an example but not by way of limitation, each carrier among the multiple carriers can associate the priority of the logical channel according to the following rules:

[0158] When the priority associated with the second carrier among the multiple carriers includes the priority of the first logical channel, the priority associated with the second carrier further includes the priorities of the logical channels among the m logical channels that are lower than the priority of the first logical channel. The second carrier is any one of the multiple carriers, and the first logical channel is any one of the m logical channels.

[0159] That is to say, when determining the associated priority of the second carrier, once it is determined that the second carrier will be associated with priority X, then all priorities lower than X should be associated with the second carrier.

[0160] For example, assume that the terminal device has 8 logical channels, and each logical channel corresponds to a priority. For example, assume that the priority of logical channel 1 is 1, the priority of logical channel 2 is 2, and so on, and the priority of logical channel 8 is 8. If the terminal device has 3 carriers. For example, carrier 1, carrier 2, and carrier 3.

[0161] Then, the 3 carriers can associate the priorities of the logical channels in the following form:

[0162] The priorities associated with carrier 1 include: 1, 2, 3, 4, 5, 6, 7, 8.

[0163] The priorities associated with carrier 2 include: 5, 6, 7, 8.

[0164] The priorities associated with carrier 3 include: 7, 8.

[0165] It should be understood that in the embodiments of the present invention, when the terminal device determines the k logical channels among the n logical channels, it can determine the k logical channels by analyzing which logical channels among the n logical channels have priorities included in the priorities associated with the first carrier. The terminal device can also determine the k logical channels by other means, and the embodiments of the present invention do not make specific limitations.

[0166] The following is an exemplary description.

[0167] Optionally, as an embodiment, the terminal device can determine the k logical channels by analyzing the priorities of some of the n logical channels.

[0168] Specifically, the terminal device may first determine a second logical channel among the n logical channels, and the priority of the second logical channel belongs to the priority associated with the first carrier; then determine the k logical channels according to the priority of the second logical channel. The second logical channel in the embodiments of the present invention may be any logical channel among the n logical channels that belongs to the priority associated with the first carrier. More specifically, the terminal device may determine the k logical channels by comparing the priority associated with the first carrier with the priorities of some of the n logical channels.

[0169] For example, among the n logical channels, the terminal device may determine the logical channels with priorities lower than that of the second logical channel as the k logical channels.

[0170] For another example, among the n logical channels, the terminal device may determine the logical channels with priorities higher than that of the second logical channel as the k logical channels.

[0171] In this case, each carrier among the multiple carriers may associate with the priorities of logical channels according to the following rules:

[0172] The priorities associated with each carrier among the multiple carriers do not overlap.

[0173] For example, assume that the terminal device has 8 logical channels, and each logical channel corresponds to a priority. For example, assume that the priority of logical channel 1 is 1, the priority of logical channel 2 is 2, and so on, and the priority of logical channel 8 is 8. If the terminal device has 3 carriers. For example, carrier 1, carrier 2, and carrier 3.

[0174] Then, the 3 carriers may associate with the priorities of logical channels in the following form:

[0175] The priorities associated with carrier 1 include: 1, 2, 3, 4.

[0176] The priorities associated with carrier 2 include: 5, 6.

[0177] The priorities associated with carrier 3 include: 7, 8.

[0178] In the embodiments of the present invention, since only the priority of the second logical channel is compared with the priority associated with the first carrier, and then the MAC PDU transmitted on the first carrier is determined, which does not conflict with the packet assembly criterion of the MAC PDU in the prior art, therefore, the compatibility between the embodiments of the present invention and the prior art can be maximally improved.

[0179] As another embodiment, the terminal device may determine the k logical channels by comparing the priority associated with the first carrier with the priorities of each of the n logical channels.

[0180] For example, the terminal device determines the k logical channels among the n logical channels, and the priority of each logical channel among the k logical channels is lower than the priority associated with the first carrier.

[0181] For another example, the terminal device determines the k logical channels among the n logical channels, and the priority of each logical channel among the k logical channels is higher than the priority associated with the first carrier.

[0182] In this case, each carrier among the multiple carriers may associate the priority of the logical channel according to the following rules:

[0183] Each carrier among the multiple carriers is only associated with one priority.

[0184] For example, assume that the terminal device has 8 logical channels, and each logical channel corresponds to a priority. For example, assume that the priority of logical channel 1 is 1, the priority of logical channel 2 is 2, and so on, and the priority of logical channel 8 is 8. If the terminal device has 3 carriers. For example, carrier 1, carrier 2, and carrier 3.

[0185] Then, the 3 carriers may associate the priority of the logical channel in the following form:

[0186] The priorities associated with carrier 1 include: 1.

[0187] The priorities associated with carrier 2 include: 5.

[0188] The priorities associated with carrier 3 include: 7.

[0189] In the embodiments of the present invention, since only the priority of each logical channel among the n logical channels is compared with the priority associated with the first carrier, and then the MAC PDU transmitted on the first carrier is determined, it does not conflict with the packet assembly criterion of the MAC PDU in the prior art. Therefore, the compatibility between the embodiments of the present invention and the prior art can be maximally improved.

[0190] It should be understood that each number in this embodiment is for illustrative purposes. The original intention of the embodiments of the present invention is to illustrate the implementation manner of associating the priority of the logical channel with the carrier, and the implementation manner of determining the carrier for transmitting the MAC PDU during the process of assembling the MAC PDU by the terminal device.

[0191] In an embodiment of the present invention, a method for generating data applicable to a Packet Data Convergence Protocol (PDCP) data replication scenario is further provided. The terminal device is configured with a third logical channel, a fourth logical channel, and at least one carrier. The third logical channel and the fourth logical channel are used for Packet Data Convergence Protocol (PDCP) data replication. Optionally, the third logical channel and the fourth logical channel are associated with the same PDCP entity, and support the PDCP entity to perform PDCP replication transmission. Optionally, the priorities of the third logical channel and the fourth logical channel are the same.

[0192] Specifically, the terminal device may, when a first condition is met, generate a Medium Access Control (MAC) protocol data unit (PDU) for a first carrier among the at least one carrier, where the MAC PDU includes the Radio Link Control (RLC) PDU of the third logical channel among the third logical channel and the fourth logical channel.

[0193] Optionally, the first condition includes: there is no data to be transmitted on the fourth logical channel. In this case, the terminal device may preferentially transmit the RLC PDU of the fourth logical channel. Further optionally, after transmitting the RLC PDU of the fourth logical channel, the RLC PDU of the third logical channel may be transmitted.

[0194] Optionally, the first condition includes: there is data to be transmitted on both the third logical channel and the fourth logical channel. In this case, the terminal device may preferentially transmit the RLC PDU of the third logical channel. Further optionally, after transmitting the RLC PDU of the third logical channel, the RLC PDU of the fourth logical channel may be transmitted.

[0195] Optionally, the first condition includes: the third logical channel is associated with the first carrier.

[0196] Optionally, the association relationship between the third logical channel and the first carrier is determined by the terminal device, or the association relationship between the third logical channel and the first carrier is configured by the network device.

[0197] Optionally, the third logical channel and the fourth logical channel are determined by the terminal device, or the third logical channel and the fourth logical channel are configured by the network device.

[0198] It should also be understood that the above method for generating data in the PDCP data replication scenario can also be incorporated into Figure 4 the method for generating data shown. Specifically, the terminal device may determine the third logical channel and the fourth logical channel among the n logical channels, and then select only one logical channel from the third logical channel and the fourth logical channel as the logical channel among the k logical channels. For the sake of brevity, it will not be elaborated here.

[0199] The above has given an exemplary description of the MAC PDU for the terminal device to determine the first carrier. However, it should be noted that in the embodiments of the present invention, after determining the first carrier, carrier reselection can also be performed. The following gives an exemplary description of the implementation manner that allows the terminal device to perform carrier reselection:

[0200] Optionally, in one implementable manner, the terminal device can determine whether to allow carrier reselection according to the channel busy rate of the first carrier and a first threshold. For example, when the channel busy rate of the first carrier is greater than the first threshold, the terminal device is allowed to perform carrier reselection. For another example, when the busy rate of the first carrier is less than or equal to the first threshold value, the terminal device is not allowed to perform carrier reselection. It should be understood that the above takes the terminal device determining whether to allow carrier reselection by the channel busy rate of the first carrier and the first threshold as an example. In other embodiments, the terminal device can also determine whether it is allowed to perform carrier reselection through other information. For example, the load of the first carrier and the corresponding threshold value.

[0201] The following gives an exemplary description of the value of the first threshold:

[0202] Optionally, the priority of each logical channel is respectively associated with a threshold.

[0203] Optionally, the first threshold is the highest value among the thresholds associated with the priorities of the k logical channels.

[0204] Optionally, the first threshold is the lowest value among the thresholds associated with the priorities of the k logical channels.

[0205] Optionally, the first threshold is the highest value among the thresholds associated with the priority associated with the first carrier.

[0206] Optionally, the first threshold is the lowest value among the thresholds associated with the priority associated with the first carrier.

[0207] Optionally, the first threshold is the highest value among the thresholds associated with the following priorities:

[0208] The priority associated with the first carrier, and the priorities lower than the priority associated with the first carrier.

[0209] Optionally, the first threshold is the lowest value among the thresholds associated with the following priorities:

[0210] The priority associated with the first carrier, and the priorities lower than the priority associated with the first carrier.

[0211] Optionally, the first threshold is the highest value among the thresholds associated with the following priorities:

[0212] The priority associated with the first carrier, and priorities higher than the priority associated with the first carrier.

[0213] Optionally, the first threshold is the lowest value among the thresholds associated with the following priorities:

[0214] The priority associated with the first carrier, and priorities higher than the priority associated with the first carrier.

[0215] In addition, an embodiment of the present invention also provides a method for configuring a logical channel. Among them, this method for configuring a logical channel can be applied to a terminal device. This method for configuring a logical channel can enable the terminal device to be configured with at least one logical channel. At least one of the above logical channels includes a first logical channel, and the first logical channel is associated with at least one first reliability requirement.

[0216] It should be understood that in the embodiments of the present invention, the specific manifestation form of the reliability requirement is not limited. For example, a low value may represent a high reliability requirement. For another example, a high value may represent a low reliability requirement.

[0217] Optionally, the terminal device may determine whether to associate the first logical channel with the logical channel group according to the association relationship between the logical channel group configured by the network and at least one second reliability requirement.

[0218] For example, when at least one of the above at least one second reliability requirements includes at least one of the above at least one first reliability requirements, it is determined to associate the first logical channel with the logical channel group.

[0219] For another example, when at least one of the above at least one second reliability requirements does not include the above at least one first reliability requirements, it is determined not to associate the first logical channel with the logical channel group.

[0220] Optionally, the terminal device may also trigger a data cache report according to the reliability requirements associated with at least one of the above logical channels.

[0221] For example, when data arrives at the first logical channel, if the reliability requirement associated with the first logical channel is higher than that of other logical channels with existing data to be transmitted, a data cache report is triggered.

[0222] In the embodiments of the present invention, taking the reliability requirement associated with the first logical channel being higher than that of other logical channels with existing data to be transmitted as an example, the implementation manner of triggering a data cache report is described. However, it should be understood that in other embodiments, when triggering a data cache report, the terminal device also needs to meet other conditions. The following is an exemplary description:

[0223] Optionally, the above-mentioned other logical channels with existing data to be transmitted and the first logical channel are for the same destination address.

[0224] Optionally, the above-mentioned other logical channels with existing data to be transmitted are associated with a logical channel group.

[0225] Optionally, the first logical channel is associated with a logical channel group.

[0226] Optionally, the logical channel group associated with the first logical channel is different from the logical channel group associated with the above-mentioned other logical channels with existing data to be transmitted.

[0227] Optionally, the reliability requirement associated with the logical channel group associated with the first logical channel is higher than the reliability requirement associated with the logical channel group associated with the above-mentioned other logical channels with existing data to be transmitted.
