Detailed Description
Fig. 1 shows a schematic architecture diagram of a communication system to which embodiments of the present application are applied. As shown in fig. 1, the communication system may include a control device 101, at least two network devices, a terminal device 104, and a core network 105. Two network devices are exemplarily shown in fig. 1, a network device currently providing a service to the terminal device 104, that is, a network device currently accessed by the terminal device 104 is referred to as a first network device, and a neighboring network device of the first network device, which can detect a signal by the terminal device 104, is referred to as a second network device, such as the first network device 102 and the second network device 103 in fig. 1. The control device 101 is connected to a core network 105. There may be one or more second network devices, and the embodiment of the present application is described as an example.
Optionally, in this embodiment of the present application, the first network device may be a first distribution unit; the second network device may be a second distribution unit and the control device a central unit. Possibly, the first network device, the second network device and the control device have different names in different network structures or different scenarios.
In this embodiment, the control device 101 and at least two Network devices may form an Access point device on a Radio Access Network (RAN) side in a distributed Radio Access Network.
The control device 101 is connected to a core network in a communication network, and the control device 101 is connected to and communicates with at least two network devices. Optionally, the control device 101 and the at least two network devices may be connected through an optical fiber, or the control device 101 and the at least two network devices may be connected through other communication lines.
A wireless connection is established between any one of network device 102 and network device 103 and terminal device 104 through a wireless interface (which may also be referred to as an air interface or air interface). The radio interface may be, for example, a radio interface based on various mobile communication technologies, for example, a radio interface based on a fourth generation mobile communication network technology (4G) standard including Time Division Long Term Evolution (TD-LTE) and Frequency Division duplex Long Term Evolution (FDD-LTE) communication technologies, or a radio interface based on a fifth generation mobile communication network technology (5G) standard.
The radio connection between the terminal device 104 and the radio access network side comprises one or more radio bearers (including a signalling bearer and a data bearer). The radio bearer is a generic term of a series of protocol layers allocated by the radio access network side (in the implementation environment of the present application, corresponding to the control device 101+ the network device 102+ the network device 103) to the terminal device 104 and a configuration of each protocol layer, for example, the radio bearer may include functions and configurations of PDCP, RLC, and MAC protocol layers. Further, the radio bearer may also include the functionality and configuration of the physical layer PHY protocol stack. The radio bearer provides data communication capacity from the terminal equipment to the access network, and the complete protocol stack formed by the series of protocol layers reflects the transmission process of signaling or data in the network from the upper layer protocol of the sending side to the lower layer protocol of the sending side and then from the lower layer protocol of the receiving side to the upper layer protocol of the receiving side.
For example, fig. 1a exemplarily shows a schematic structural diagram of a protocol layer of a Radio bearer provided in an embodiment of the present application, as shown in fig. 1a, a Radio Link Control (RLC) layer 111, a Medium Access Control (MAC) layer 112, and a Physical (PHY) layer 113 are correspondingly configured in a network device 102, and an RLC layer 121, an MAC layer 122, and a PHY layer 123 are correspondingly configured in a network device 103. A Radio Resource Control (RRC) layer 131 and a Packet Data Convergence Protocol (PDCP) layer 132 are configured in the Control device 101. The terminal device 104 is configured with a MAC layer 141, two RLC layers, an RLC layer 142 and an RLC layer 143, a PDCP layer 144, and an RRC layer 145. Alternatively, the RLC layer may not be necessarily limited to 2 RLC layers, and only two RLC layers are schematically shown in the figure. The terminal device 104 may further include a MAC layer 141, an RLC layer, a PDCP layer 144, and an RRC layer 145.
In the embodiment of the present application, other protocol stack division modes also exist, for example, according to the configuration of the network, when the CU and the DU are deployed, the RRC may be divided into the CU, and the PDCP, RLC, and MAC protocol stacks may be divided into the DU. Specific other possible protocol stack partitioning modes can refer to TR 38.801 v14.0.0.
During wireless transmission, when signaling or data is transmitted from the radio access network side to the terminal device through the radio bearer, the radio access network side sequentially passes through the RRC layer and the PDCP layer of the control device, then sequentially passes through the RLC layer, the MAC layer, and the PHY layer of the network device for processing, and then transmits the processed signaling or data to the terminal device through the radio frequency unit of the radio access network side, and the processed signaling or data is received by the radio frequency unit of the terminal device and sequentially passes through the PHY layer, the MAC layer, the RLC layer, and the PDCP layer of the terminal device for processing. Correspondingly, when signaling or data is transmitted from the terminal equipment to the radio access network side through the radio bearer, the processing sequence of each protocol layer is opposite to the sequence described above, specifically, the signaling or data is transmitted to the radio access network side by the radio frequency unit after passing through the PDCP layer, the RRC layer, the RLC layer and the MAC layer of the terminal equipment, is received by the radio frequency unit of the radio access network side, and then is processed sequentially through the PHY layer, the MAC layer and the RLC layer of the network equipment, and the PDCP layer and the RRC layer of the control equipment.
In practical applications, the configuration of each protocol layer of the radio bearer is not limited to the above form, for example, in a 5G or next generation mobile communication network, other protocol layer configurations may be adopted, for example, more or less protocol layers are included in the complete protocol stack of one radio bearer, and the functions of each protocol layer may be different from the corresponding protocol layers in fig. 1 a.
The terminal device 104 in the embodiment of the present application may also be referred to as a User Equipment (User Equipment), which is a device with a wireless transceiving function, and may be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with Wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a Wireless terminal in industrial control (industrial control), a Wireless terminal in self driving (self driving), a Wireless terminal in remote medical (remote medical), a Wireless terminal in smart grid (smart grid), a Wireless terminal in transportation security (transportation security), a Wireless terminal in smart city (smart city), a Wireless terminal in smart home (PDA), a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (Local Loop, Personal Digital Assistant (PDA), a Personal Digital Assistant (wlan), a Personal Digital Assistant (WLL), and a Wireless communication device with Wireless transceiving function, Computing devices or other processing devices connected to wireless modems, vehicle devices, wearable devices, terminal devices in future 5G networks, and the like.
In the embodiments of the present application, the term "base station" includes, but is not limited to, a node, a station controller, an Access Point (AP), or any other type of interface device capable of operating in a wireless environment.
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
In this embodiment of the present application, the beam may be called beam, for example, the transmission beam may refer to the distribution of signal strength formed in different spatial directions after the signal is transmitted through the antenna, and the reception beam may refer to the distribution of signal strength of the wireless signal received from the antenna in different spatial directions. It is to be understood that one or more antenna ports of a beam may also be considered as a set of antenna ports, that is to say that one set of antenna ports comprises at least one antenna port.
Specifically, the beam may refer to a precoding vector having a certain energy transmission directivity and may be capable of identifying the precoding vector through the index information, where the energy transmission directivity refers to that, in a certain spatial position, a signal subjected to precoding processing by the precoding vector has a better receiving power, such as meeting a receiving demodulation signal-to-noise ratio, and in other spatial positions, a signal subjected to precoding processing by the precoding vector has a lower receiving power, and does not meet the receiving demodulation signal-to-noise ratio. Different communication devices may have different precoding vectors, i.e. correspond to different beams, and one communication device may use one or more of a plurality of different precoding vectors at the same time, i.e. may form one beam or a plurality of beams at the same time, depending on the configuration or capabilities of the communication device. A beam may be understood as a spatial resource. The beam may be identified by identification information, and optionally, the identification information may correspond to a resource Identifier (ID) corresponding to the user, for example, the identification information may correspond to an ID or a resource of a Channel state information Reference Signal (CSI-RS) configured; or may be an ID or a resource of a correspondingly configured uplink Sounding Reference Signal (SRS). Alternatively, the identification information may also be identification information that is explicitly or implicitly carried by a Signal or channel carried by a beam, for example, the identification information includes, but is not limited to, identification information that indicates a beam by a Synchronization Signal or a broadcast channel transmitted by the beam, and includes, but is not limited to, identification information that indicates the beam by a Synchronization Signal block (SS block) transmitted by the beam, where the SSblock includes at least a Primary Synchronization Signal (PSS) and/or a secondary Synchronization Signal (SSs) and/or a broadcast channel (PBCH). It will be appreciated that the above description of beams applies to beams within each cell when the communication device corresponds to one or more cells.
It can be understood that, in the embodiment of the present application, the identity of the cell or the cell identity may include at least one of the following: global Cell Identity (GCI) of a Cell, Physical Cell Identity (PCI), frequency, Synchronization Signal (SS) pattern, and beam information of a Cell.
For the extension of signal quality, the signal quality in the embodiment of the present application is a broad concept, and may be understood as a parameter for measuring the signal receiving condition, for example, at least one of the following may be included: signal Received Power (RSRP), Signal received Quality (RSRQ), and the like.
In the embodiment of the present application, the layer 3 signaling may include RRC layer signaling; the layer 2 signaling may include signaling of at least one of a PDCP layer, an RLC layer, and a MAC layer; the layer 1 signaling may include PHY layer signaling. In the embodiment of the present application, the layer 1 and/or layer 2 measurement information includes measurement information transmitted using layer 1 and/or layer 2 signaling; the layer 3 measurement information includes measurement information transmitted using layer 3 signaling.
Example one
Based on the above, to further introduce the solutions provided in the embodiments of the present application, fig. 2 schematically illustrates a flowchart of a communication method provided in the embodiments of the present application, and as shown in fig. 2, the method includes the following contents.
Step 201, the terminal device measures a beam of the second network device to obtain first measurement information, where the first measurement information includes a beam identifier of each beam of N beams of the first cell and a cell identifier of the first cell, where N is a positive integer, and the beam identifiers are corresponding to the second network device.
In this embodiment of the present application, the second network device is a neighboring network device of the first network device, and the neighboring network device of the first network device that can be measured by the terminal device may include one or more neighboring network devices.
The first network equipment is network equipment for providing service for the terminal equipment. In this embodiment, a network device may correspond to one or more cells (cells), and the signal quality of a beam of at least one cell corresponding to the network device may be measured by a terminal device, and then the measured signal quality of the beam of the at least one cell may be reported to the network device. The at least one cell that may be measured may include the first cell and other cells. It is understood that, when a network device corresponds to a cell, the signal quality of the beam of the cell to which the network device corresponds may also be referred to as the signal quality of the beam of the network device.
It can be understood that the first measurement information may include a beam identifier of each of the N beams, and further may include a cell identifier of a cell corresponding to the N beams of the second network device. For example, assuming that there are beams 1-10 of cell 1 and beams 1-10 of cell 2 that can be measured, the first measurement information may include cell 1: identification information cell 2 of beam 1-10: and (5) identification information of beam 1-10. Cell 1 or cell 2 may be regarded as a first cell, which is not limited in this embodiment of the present application.
Further, in order to enable the first network device to better manage mobility of the terminal device, the first measurement information may further include signal quality of each of the N beams, and further may further include signal quality of the first cell.
Step 202, the terminal device sends first measurement information to the first network device.
The first measurement information may be carried in layer 1 signaling and/or layer 2 signaling, for example, the first measurement information may be carried in physical layer signaling or medium access control MAC layer signaling. For another example, the first measurement information may be carried in signaling of at least one of a PDCP layer, an RLC layer, a MAC layer, and physical layer signaling.
Correspondingly, the first network device receives the first measurement information.
In the embodiment of the application, the first measurement information is transmitted through physical layer signaling or MAC layer signaling instead of layer 3 signaling (for example, RRC signaling) in the process of transmitting the first measurement information from the terminal device to the first network device, so that transmission of layer 3 signaling in the process of transmitting the measurement information can be reduced, and system overhead is reduced.
Optionally, the terminal device may also measure a cell and/or a beam of the first network device to obtain second measurement information, and optionally, the terminal device may send the second measurement information to the first network device, and accordingly, the first network device receives the second measurement information. The second measurement information may be carried in layer 1 signaling and/or layer 2 signaling, for example, the second measurement information may be carried in physical layer signaling or medium access control MAC layer signaling. For another example, the second measurement information may be carried in signaling of at least one of a PDCP layer, an RLC layer, a MAC layer, and physical layer signaling. And the content included in the second measurement information may be similar to the first measurement information, for example, the second measurement information includes a beam identifier of each of R beams of the second cell corresponding to the first network device, where R is a positive integer.
In the second measurement information, the signal quality of the R beams may also be included, such as the signal quality of each of the R beams or the signal quality of at least one of the R beams. Further, the signal quality of the cell corresponding to the R beams may also be included. Further, the cell identifier of the cell corresponding to the R beams of the first network device may also be included.
Optionally, in order to increase flexibility of the system, in the embodiment of the present application, in addition to the first network device acquiring the first measurement information through the above optional implementation, the first network device may also acquire the measurement information through other manners, where the measurement information may include measurement information of the first network device and/or measurement information of the second network device.
For example, the first network device receives second indication information sent by the control device, where the second indication information is used to determine a manner of obtaining the measurement information, and specifically, the manner in which the second indication information indicates that the first network device obtains the measurement information may be receiving the measurement information sent by the terminal device, or the manner in which the second indication information indicates that the first network device obtains the measurement information may also be obtained by the first network device based on an uplink reference signal sent by the terminal device.
In a possible case, when the second indication information indicates that the first network device acquires the measurement information in a manner of receiving the measurement information sent by the terminal device, the first network device acquires the measurement information according to the received first measurement information of the second network device and/or the received second measurement information of the first network device sent by the terminal device. In another possible case, when the second indication information indicates that the manner of obtaining the measurement information is that the first network device obtains based on the uplink reference signal sent by the terminal device, the first network device measures the uplink reference signal sent by the terminal device to generate the measurement information of the first network device, and the second network device measures the uplink reference signal sent by the terminal device to generate the measurement information of the second network device. It can be understood that, when the second indication information indicates that the manner of obtaining the measurement information is that the first network device obtains the measurement information based on the uplink reference signal sent by the terminal device, the first network device may also receive the first measurement information of the second network device and/or the second measurement information of the first network device sent by the terminal device, which is not limited in this embodiment of the application.
It can be understood that, in the embodiment of the present application, the timing for acquiring the second indication information is not limited, for example, before the first network device receives the first measurement information, or after the first network device receives the first measurement information. Further, in an optional implementation, before the first network device receives the first measurement information, the first network device obtains the second indication information, and may inform the terminal device in some ways that the first measurement information and/or the second measurement information do not need to be reported.
Further, after the first network device obtains the first measurement information, various optional embodiments are provided in the examples of the present application, and in an optional embodiment, the first network device forwards the first measurement information to the control device. Optionally, if the first network device further receives the second measurement information, the first network device may also forward the second measurement information to the control device. The first network device may forward the first measurement information and/or the second measurement information through the first indication information. Therefore, the control device obtains the measurement information of the first network device and/or the second network device, and can better manage and control the mobility of the terminal device.
In another optional implementation, the first measurement information may further include a signal quality of each of the N beams. Then, after the first network device obtains the first measurement information, if the first network device determines that the signal quality of M beams of the N beams meets the indication information reporting condition, the first network device sends the first indication information to the control device, where M is a positive integer less than or equal to N. That is to say, the first network device performs, according to the signal quality of N beams in the received first measurement information, determination in combination with an indication information reporting condition, and sends, to the control device, first indication information if the first network device determines that the signal quality of M beams in the N beams meets the indication information reporting condition, where the first indication information may provide reference information for the control device whether to switch the terminal device from the first network device to the second network device, and may share the workload of some control devices for determining whether to switch the terminal device from the first network device to the second network device.
Based on the above-mentioned scheme that the first network device sends the first indication information to the control device, an embodiment of the present application provides a possible application scenario, where the application scenario is that the terminal device switches between two network devices, and the control devices corresponding to the two network devices are the same, that is, the control devices corresponding to the first network device and the second network device are the same, so that after the terminal device switches, although the network device connected to the terminal device changes, the control device connected to the terminal device does not change, and therefore, the RRC connection between the terminal device and the RAN may not change. In addition, after the terminal device is switched between two Network devices corresponding to the same control device, the connection between the terminal device and the core Network is not changed, because the connection between the terminal device and the core Network is realized through the connection between the control device and the core Network, that is, the connection between the terminal device and a Radio Access Network (RAN) and the connection between the terminal device and the core Network are not changed. Optionally, the embodiment of the present application may also be applicable to other scenarios, for example, a scenario that a control device connected to a terminal device changes, which is not limited in the embodiment of the present application. Optionally, in this embodiment of the present application, a scenario in which the terminal device is switched between two network devices corresponding to the same control device may include a switching scenario of an intra-CU inter-DU.
It can be understood that the first indication information sent by the first network device to the control device may include a beam identifier of at least one beam of the M beams, optionally, an identifier of a first cell of the second network device, and the first indication information may further include a cell signal quality of a cell corresponding to the second network device and/or a beam signal quality of the M beams.
By the above scheme, the first network device can perform pre-judgment according to the first measurement information, and when the indication information reporting condition is met, the first indication information is sent to the control device to provide the reference information for the control device, so that the workload of some control devices for judging whether to switch the terminal device from the first network device to the second network device can be shared.
In an optional implementation, if the first network device obtains first measurement information of the second network device and second measurement information of the first network device, the first network device determines signal qualities of M beams of N beams of a first cell corresponding to the second network device, and signal qualities of R beams of a second cell corresponding to the first network device meet an indication information reporting condition, and sends the first indication information to the control device.
Optionally, the first indication information may further include a beam identifier of at least one beam of the R beams. Optionally, the first indication information may further include at least one of a beam signal quality of at least one beam of the R beams of the first network device, a cell identifier of the second cell, and a cell signal quality of a cell corresponding to the first network device.
In the above optional embodiment, the condition for reporting the indication information may be that the signal quality of M beams is better, that the signal quality of R beams is poorer, or that the signal quality of the first cell is better than the signal quality of the cell corresponding to the first network device.
The signal quality of the M beams of the second network device is better, which may be that the signal quality of the M beams of the second network device is higher than a first threshold; the poor signal quality of the R beams of the first network device may be that the signal quality of the R beams of the first network device is below a second threshold. In the embodiment of the present application, the first and second thresholds are merely for distinguishing and are not limited.
It can be understood that the condition for reporting the indication information may have various embodiments, and the embodiment of the present application does not limit this.
The following lists several cases that the reporting condition of the indication information is that the signal quality of M beams is good: the signal quality of each of the M beams of the second network device is above a first signal quality threshold; the average of the signal qualities of the M beams of the second network device is above a second signal quality threshold; the signal quality of each of the M beams of the second network device is above a third signal quality threshold, and M is greater than the first number threshold.
Then, enumerating several cases that the reporting condition of the indication information is that the signal quality of the R beams is poor: the signal quality of at least one of the R beams of the first network device is below a fourth signal quality threshold; the average of the signal quality of S of the R beams of the first network device is below a fifth signal quality threshold, S being a positive integer no greater than R.
Then enumerate several cases that the signal quality of the first cell is better than the signal quality of the corresponding cell of the first network device under the reporting condition of the indication information: the average of the signal qualities of the M beams of the second network device is higher than the average of the signal qualities of the S beams of the first network device; the difference value between the average value of the signal qualities of the M wave beams of the second network equipment and the average value of the signal qualities of the S wave beams of the first network equipment is not less than a first difference threshold value; the best signal quality of the M beams of the second network device is greater than the best signal quality of the S beams of the first network device; the difference between the best signal quality in the M beams of the second network device and the best signal quality in the S beams of the first network device is not less than a second difference threshold, and the value of N is greater than the measured number of beams of the cell corresponding to the first network device.
Any two values of the first signal quality threshold to the fifth signal quality threshold may be equal or different, and the first difference threshold and the second difference threshold may be equal or different. Alternatively, S may be equal to R.
It can be understood that the indication information reporting condition refers to a condition for determining whether to send the first indication information, where the indication information reporting condition may be preset, or may be configured by the control device to send to the first network device, and this is not limited in this embodiment of the present application. In addition, optionally, the reporting condition of the indication information may be different according to different requirements or network settings or scenarios.
In the embodiment of the present application, the first to fifth of the first to fifth signal quality thresholds are merely for distinction and have no limiting meaning.
Optionally, the first indication information may include an identifier of the first cell and beam identifiers of all beams in the M beams, or in some scenarios, for example, under a condition that there is a limit to the number of beams reported by the first network device, the first indication information includes an identifier of the first cell and a beam identifier of at least one beam in the M beams.
Further, in this embodiment of the application, the first indication information further includes at least one of the following: the signal quality of the first cell and the signal quality of at least one beam in the M beams enable the control device to obtain more stable or more detailed quality information of the target cell or beam, and better perform switching judgment.
After the control device receives the first indication information, optionally, under the condition that it is determined that the terminal device needs to be switched to the second network device according to the first indication information, the terminal device is switched to the second network device. It is to be understood that the handover to the second network device is herein understood as a handover to a cell corresponding to the second network device, for example, the first cell.
That is to say, the first indication information in the embodiment of the present application provides a result of pre-determination for the control device, so that the control device can further determine whether to switch the terminal device to the second network device according to the first indication information, thereby simplifying a determination process for determining whether to switch the terminal device to the second network device by the control device.
In another alternative embodiment, the control device may directly switch the terminal device to the second network device according to the first indication information. Optionally, the control device may select one or more beams from the M beams included in the received first indication information as the target beam to be switched of the terminal device.
Optionally, in this embodiment of the present application, on the terminal device side, the first measurement information may be sent through layer 1 and/or layer 2 signaling, and may also be sent through layer 3 signaling. Optionally, in order to determine whether to use layer 1 and/or layer 2 signaling or layer 3 signaling for sending the measurement information, the terminal device may perform a judgment once, determine whether the first network device and the second network device are connected to the same control device through the judgment, and execute step 202 after determining that the first network device and the second network device are connected to the same control device. It will be appreciated that the determination of which signaling to send the second measurement information may also be made in a similar manner as sending the first measurement information.
The terminal device may determine whether the first network device and the second network device are connected to the same control device in various ways, which is exemplified by the following way a1, way a2, and way a3 in this embodiment of the application.
Mode a1
The terminal device receives control device indication information sent by a first network device or sent by a control device connected with the first network device, and determines that the first network device and a second network device are connected with the same control device according to the received control device indication information, wherein the control device indication information is used for indicating whether the second network device and the first network device are connected with the same control device. Optionally, the indication information of the control device may be sent to the terminal device through a report condition of the measurement information. Therefore, the terminal equipment can determine whether the second network equipment and the first network equipment are connected with the same control equipment or not by receiving the indication information of the control equipment, so that the terminal equipment can select proper signaling to send the measurement information, and the flexibility of the scheme is improved.
As an example, the terminal device receives a neighbor cell list, where the neighbor cell list includes neighbor cells of the first network device, and control device indication information is added in the neighbor cell list to indicate whether each neighbor cell and a cell corresponding to the first network device are connected to the same control device, for example, the neighbor cell list includes a neighbor cell 1 and a neighbor cell 2, where the control device indication information of the neighbor cell 1 is 1, which indicates that the network device of the neighbor cell 1 and the first network device are connected to the same control device, and the control device indication information of the neighbor cell 2 is 0, which indicates that the network device of the neighbor cell 2 and the first network device are not connected to the same control device.
Mode a2
The method comprises the steps that terminal equipment receives identification indication information of control equipment connected with first network equipment and identification indication information of control equipment connected with second network equipment, wherein the identification indication information is sent by the control equipment connected with the first network equipment; and if the identification indication information of the control equipment connected with the first network equipment is the same as the identification indication information of the control equipment connected with the second network equipment, determining that the first network equipment and the second network equipment are connected with the same control equipment. In this manner, the terminal device is burdened with steps of partial judgment of the control device.
Optionally, in this embodiment of the present application, the identification indication information may be an identification, or may be related information capable of indicating an identification. For example, the identification indication information of the control device connected to the first network device may be the identification of the control device connected to the first network device directly, or may be a flag value. For example, the identification indication information of the control devices connected to the first network device and the second network device is a flag value, for example, the flag value of the control device connected to the first network device is 0, and if the flag value of the control device connected to the second network device is 0, the terminal device determines that the first network device and the second network device are connected to the same control device; if the flag value of the control device connected to the second network device is not 0, for example, 1, the terminal device determines that the first network device and the second network device are connected to different control devices.

Optionally, one second network device may correspond to one measurement information reporting condition, or multiple second network devices may correspond to one measurement information reporting condition, where multiple measurement information reporting conditions may be sent through multiple layer 3 signaling respectively, or sent through one layer 3 signaling.
It is understood that the content of the measurement information reporting condition may refer to the description in the existing protocol TS 36.331 v14.2.2.

Example two
The second embodiment can be implemented alone or in combination with any possible implementation scheme of the first embodiment and the first embodiment, and the embodiments of the present application are not limited. Based on the above, the embodiment of the present application further provides a communication method. The communication scheme provided by the embodiment of the present application may be applicable to a scenario in which a wireless access network side has multiple MAC layer entities, but a terminal device side has only one MAC layer entity, for example, the scenario may be as shown in fig. 1 a. On the radio access network side, a cell may correspond to a plurality of network devices, such as the first network device 102 and the second network device 103 shown in fig. 1a, each network device includes one MAC layer entity, that is, a cell includes a plurality of MAC layer entities. On the terminal device side, for a serving cell, the terminal device includes a MAC layer entity, such as the MAC layer 141 entity shown in fig. 1 a; or, at the terminal device side, multiple serving cells may correspond to one MAC layer entity, and different serving cells at the radio access network side may correspond to different MAC layer entities.
In an alternative embodiment, there are several radio bearers for the terminal device, and there are several RLC layer entities and PDCP layer entities, that is, the radio bearers and PDCP layer entities and the RLC layer entities are in one-to-one correspondence. Optionally, in this embodiment of the present application, the logical channel is a transmission channel between an RLC layer entity and an MAC layer entity, and the logical channel and the RLC layer entity may be in one-to-one correspondence, for example, the terminal device includes 4 radio bearers, so that the terminal device side may respectively correspond to 4 PDCP layer entities and 4 RLC layer entities, and the logical channel between the RLC layer entity and the MAC layer entity is also 4. In another alternative, in a multi-connection scenario, one radio bearer may correspond to two RLC layer entities and two logical channels. Optionally, one radio bearer may also correspond to one RLC layer entity and two logical channels. The embodiments of the present application do not limit this.
It is understood that each protocol layer entity mentioned above refers to a functional entity located in a corresponding protocol layer and implementing a corresponding logical function, and the logical function may refer to a protocol definition.
At a sending end, after data of different Logical channels of the sending end reaches an MAC layer entity of the sending end, the MAC layer entity may use an identifier (LCH ID) of the Logical Channel to mark which Logical Channel the data received by the MAC layer entity comes from according to information of the Logical Channel from which the data comes, and then put the data of the Logical channels into a Hybrid Automatic Repeat reQuest (HARQ) process to send to a receiving end. At the receiving end, the MAC layer entity of the receiving end receives data including a plurality of logical channels, and may also identify the logical channel of each data according to the logical channel ID, and the MAC layer entity transmits the corresponding data to the corresponding RLC layer entity through the corresponding logical channel according to the logical channel ID.
For downlink data, because the wireless network side has a plurality of MAC layer entities, different logical channels and MAC layer entities on the wireless network side have a corresponding relationship, for example, logical channel 1 and logical channel 2 correspond to MAC layer entity 1, and logical channel 3 and logical channel 4 correspond to MAC layer entity 2. For downlink data from the wireless network side to the terminal device, although the terminal device side only has one MAC entity to receive the downlink data, the MAC entity of the terminal device side can determine, according to the logical channel ID of the received downlink data, which logical channel the received downlink data should be sent to the corresponding RLC layer entity.
In an alternative embodiment, at the network side, each MAC layer entity may use all available HARQ processes. For example, the available HARQ processes are HARQ process 0 to HARQ process 7, the HARQ processes corresponding to each MAC layer entity are HARQ process 0 to HARQ process 7, that is, each MAC layer entity can select from HARQ process 0 to HARQ process 7 when selecting the HARQ process for data or signaling.
In another optional embodiment, at the network side, the corresponding relationship between the MAC layer entity and the HARQ process may also be associated according to negotiation or predefinition at the wireless network side, for example, the MAC layer entity 1 corresponds to downlink HARQ processes 0 to 5, and the MAC layer entity 2 corresponds to downlink HARQ processes 6 to 7. In this way, the MAC layer entity 1 can select from the downlink HARQ processes 0 to 5 when selecting the downlink HARQ process for the received data, and the MAC layer entity 2 can select from the downlink HARQ processes 6 to 7 when selecting the downlink HARQ process for the received data.
The embodiment of the present application provides a communication method for uplink data sent from a terminal device to a wireless network, so that the terminal device can find a logical channel corresponding to a resource used by the terminal device to transmit the uplink data. Fig. 3 exemplarily shows a flowchart of a communication method provided in an embodiment of the present application, where the communication method may be implemented by a terminal device, or may be implemented by a chip inside the terminal device, and the following description takes the terminal device as an execution subject for example.
As shown in fig. 3, the communication method may include:
step 301, the terminal device receives resource indication information from the network device, where the resource indication information is used to indicate time-frequency location information of a resource used for transmitting uplink data.
Optionally, the resource used by the uplink data includes any one of an uplink time domain resource used by the uplink data, an uplink frequency domain resource used by the uplink data, and an uplink time-frequency resource used by the uplink data.
In an optional implementation, for the resource indication information, the network device may send the resource indication information to the terminal device through DCI signaling, where the terminal has uplink data or signaling to send the uplink data or signaling.
Step 302, the terminal device determines a logical channel corresponding to a resource used for transmitting the uplink data according to the resource indication information and the association relationship information, where the association relationship information includes information for determining an association relationship between the resource used for transmitting the uplink data and the logical channel.
Here, the association relation information may be sent by the network device or preset, and this is not limited in this embodiment of the application.
In an optional implementation, the resource indication information may be included in the association relationship information, and then the logical channel corresponding to the resource used for transmitting the uplink data is determined according to the resource indication information and the association relationship information, or may be understood as the logical channel corresponding to the resource used for transmitting the uplink data is determined according to the association relationship information.
In this embodiment, the association relationship information may include one or more corresponding relationships, as long as the association relationship information can be used to determine a logical channel corresponding to a resource used for transmitting uplink data.
Step 303, sending the uplink data corresponding to the logical channel to the network device on the resource used for transmitting the uplink data.
That is to say, in this embodiment of the present application, after determining the logical channel corresponding to the resource used for transmitting the uplink data through step 302, the uplink data on the logical channel is transmitted on the resource, and in this embodiment of the present application, the uplink data sent to the MAC layer entity through the logical channel is referred to as the uplink data corresponding to the logical channel. In the embodiment of the present application, the uplink data includes control plane data and/or data plane data.
Through the scheme, when the terminal transmits the uplink data by using the uplink resource allocated by the network in the embodiment of the application, the logical channel corresponding to the uplink resource is determined according to the association relation information, so that the uplink data of the corresponding logical channel is transmitted on the uplink resource, and the problem that the network cannot correctly or repeatedly receive the uplink data due to the fact that the terminal transmits the uplink data on the wrong logical channel on the uplink resource is solved.
As above, the association information may include one or more corresponding relationships, and the following examples a to d exemplify what the association information may include.
Example a
The association relation information includes an association relation of the uplink resource and the identifier of the logical channel.
Then, in step 302, a logical channel associated with the resource used for transmitting the uplink data may be determined according to the association relationship between the uplink resource and the identifier of the logical channel. In the embodiment of the present application, the resource used for transmitting the uplink data is an uplink resource. Therefore, the logical channel can be determined directly according to the resource used for transmitting the Uplink data, and the Uplink resource may include an Uplink grant, which may also be referred to as a UL grant for short.
Table 1 exemplarily shows a schematic table of the association between the uplink resource (taking the uplink resource as the UL grant as an example) and the identifier of the logical channel included in the association relationship information. The logical channel may be written as a local channel or LCH. The identifier of the logical channel associated with the uplink resource may be one or multiple, and finally, the terminal device may select one or multiple logical channels from the identifiers of all the logical channels associated with the uplink resource, and transmit uplink data of the selected logical channels on the UL grant.
TABLE 1 Association of uplink resources and logical channel identifiers
UL grant Logical channel 1 and logical channel 2
It can be understood that the resource indication information may be included in the association information, for example, the association information may directly include a UL grant and a logical channel identifier, where the logical channel identifier included in the association information is an identifier of a logical channel corresponding to a resource used for transmitting uplink data, so that the terminal device may directly determine, according to the association information, a UL grant used for transmitting uplink data and a logical channel identifier corresponding to uplink data allowed to be transmitted on the UL grant. In the embodiment of the present application, the association relationship Information may be carried in Downlink Control Information (DCI) sent by the wireless network side to the terminal device. In the embodiment of the present application, the logical channel corresponding to the uplink data can be dynamically specified by using the scheme provided by example a, so that the flexibility is improved. In this embodiment, the network device may be a DU.
