Description

Method and device for sending cell configuration information

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for sending cell configuration information.

Background

Currently, in a Long Term Evolution-Advanced (LTE-a) system, a transmission bandwidth may be increased by a Carrier Aggregation (CA) technology, and requirements for increasing a peak rate and a system capacity specified by the LTE-a system are met. In a case that a base station configures Carrier aggregation for a terminal, since each Carrier Cell (CC) corresponds to an independent Cell (Cell), at this time, the base station needs to configure Serving cells (Serving cells) including a Primary Cell (PCell) and a plurality of Secondary cells (scells) for the terminal, where the Serving cells are the same as the number of carriers for performing Carrier aggregation. If the size of the configuration information that the base station configures one serving cell for the terminal is s, and n serving cells need to be configured in total, the size of the configuration information included in the configuration signaling sent by the base station to the terminal is n × s, and then the overhead of the configuration signaling is large. Moreover, in a scenario where the terminal moves, the signal strength of the secondary cell configured by the terminal may not meet the requirement for serving the terminal, and at this time, the terminal needs to frequently reconfigure the secondary cell, so that the number of configuration signaling is also increased significantly. Therefore, when the terminal configures carrier aggregation, overhead of configuration signaling when performing cell configuration is large.

Therefore, in the method for receiving cell configuration information according to the embodiment of the present application, first, a network device divides cells to be configured to obtain at least one cell group, where each cell group corresponds to one configuration information, and therefore, a terminal receives an RRC signaling sent by the network device and includes the configuration information of the cell group, and each cell included in the cell group corresponds to the same configuration information, that is, the cell group configuration information, so that the terminal can configure each cell included in the cell group according to the cell group configuration information.

With reference to the fourth aspect, in a possible implementation manner, if the first identifier indicates that the configuration information of the to-be-configured cell is not configured based on the configuration information of the reference cell, the configuration information of the to-be-configured cell further includes at least one second identifier, where the at least one second identifier is respectively used to indicate whether at least one parameter in the configuration information of the to-be-configured cell is configured based on a parameter included in the configuration information of the reference cell, and if the second identifier indicates that a parameter corresponding to the second identifier in the configuration information of the to-be-configured cell is not configured based on a parameter included in the configuration information of the reference cell, the configuration information of the to-be-configured cell further includes a parameter corresponding to the second identifier.

Detailed Description

In a communication protocol of a third Generation radio communication technology (3G) and a communication protocol of a fourth Generation radio communication technology (4G), in the process of establishing RRC connection between a terminal and a base station, RRC signaling needs to carry cell configuration information, and the base station performs cell configuration for the terminal, so that the terminal performs an initial connection establishment process with the base station on a cell or starts a connection re-establishment process, where the cell may also be referred to as a serving cell, and the detailed process may be described in section 3.1 of 36.331 of 3GPP, which is not described herein again.

With the development of wireless communication technology, in a Long Term Evolution-Advanced (LTE-a) system, a transmission bandwidth can be increased by a Carrier Aggregation (CA) technology, and requirements for increasing a peak rate and a system capacity specified by the LTE-a system are met. As shown in fig. 1, the CA technology can aggregate 2-5 carrier units, each carrier unit being 20 megahertz (MHz), to realize a maximum transmission bandwidth of 100MHz, and effectively improve the uplink and downlink transmission rate.

For ease of understanding, the basic concept of carrier aggregation is briefly explained below. The carrier elements may be divided into primary carrier elements (primary CCs) and secondary carrier elements (secondary CCs). If the Carrier cells are different according to the transmission directions of the terminal and the base station, the Carrier cells may be further divided into a Downlink Primary Carrier cell (DL PCC), an Uplink Primary Carrier cell (UL PCC), a Downlink Secondary Carrier cell (DL SCC), and an Uplink Secondary Carrier cell (UL SCC). Each carrier unit corresponds to an independent cell, and then, a cell operating on the primary carrier unit may be referred to as a primary cell, and a cell operating on the secondary carrier unit may be referred to as a secondary cell. The primary cell is a cell when the terminal initially accesses, and is responsible for RRC communication with the terminal, and the primary cell is determined during connection establishment (connection establishment). The secondary cell is added, modified, and released through an RRC Connection Reconfiguration (RRC Connection Reconfiguration) message after an initial security activation procedure (initial security activation procedure), so as to provide additional radio resources, and a detailed process may be referred to in section 3.1 of 36.331 of 3GPP, which is not described herein again in this embodiment of the present invention.

A terminal in an RRC CONNECTED (RRC _ CONNECTED) state, if CA is not configured, has only one serving cell, i.e., a primary cell; if CA is configured, the serving cell set is composed of a primary cell and a plurality of secondary cells. Section 6.4 of 36.331 of 3GPP specifies the maximum number of secondary cells (maxsell-r 10), i.e., a terminal configured with carrier aggregation can be connected to 1 primary cell and a maximum of 4 secondary cells. In section 6.4 of 36.331 of 3GPP, the number of serving cells (maxServCell-r10) included in the serving cell set is specified, that is, the primary cell and all secondary cells configured by the terminal form the serving cell set of the terminal, and the serving cell set includes at most 5 serving cells, where the serving cell may be a primary cell or a secondary cell.

Each carrier cell has a corresponding index, the primary carrier cell (primary CC) index is fixed to 0, and the secondary carrier cell index of each terminal is sent to the terminal through terminal-specific RRC signaling, for a detailed explanation, see secondary cell index (scellndex-r 10) in section 6.2.2 of 36.331 of 3GPP. The carrier units aggregated by the terminal are usually from the same base station and these carrier units are synchronized. When the terminal configured with carrier aggregation uses the same Cell Radio Network Temporary Identifier (C-RNTI) in all the secondary cells. Carrier aggregation is a terminal-level property, and different terminals may have different primary cells and secondary cells.

The size of the configuration information configuring a serving cell for the terminal by the base station is different according to the content of the configuration information, that is, the configuration information includes more content, the bytes of the configuration information are large, and the configuration information includes less content, the bytes of the configuration information are small. If the size of the configuration information that the base station configures one serving cell for the terminal is s, and the number of carriers performing carrier aggregation in the prior art can reach 32 carriers, the base station needs to configure 32 serving cells for the terminal in total, and then the size of the configuration information included in the configuration signaling sent by the base station to the terminal is 32 × s, at this time, the overhead of the configuration signaling is large. Moreover, in a scenario where the terminal moves, the signal strength of the secondary cell configured by the terminal may not meet the requirement for serving the terminal, and at this time, the terminal needs to frequently reconfigure the secondary cell, so that the number of configuration signaling is also increased significantly. Therefore, in order to effectively reduce the overhead of configuration signaling when a terminal configures a cell, an embodiment of the present application provides a method for sending cell configuration information, and the basic principle of the method is as follows: firstly, a network device determines at least one cell group, and then sends an RRC signaling to a terminal, wherein the RRC signaling includes cell group configuration information of each cell group in the at least one cell group, each cell group in the at least one cell group includes at least two cells, the terminal configures each cell included in each cell group in the at least one cell group after receiving the RRC signaling sent by the network device, and the terminal configures each cell included in each cell group in the at least one cell group, which specifically includes: and the terminal configures each cell included in the cell group according to the cell group configuration information of the cell group. Therefore, the RRC signaling sent by the network equipment to the terminal comprises the configuration information of the cell groups, and each cell contained in the cell groups corresponds to the same configuration information, namely the cell group configuration information, so that the terminal can configure each cell contained in the cell groups according to the cell group configuration information.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Fig. 2 shows a simplified schematic diagram of a system architecture to which embodiments of the present application may be applied. As shown in fig. 2, the system architecture may include: the terminal 11 and the network device 12, wherein a solid line represents a range of a main serving cell corresponding to the main carrier unit and is used for implementing RRC connection and data transmission between the terminal and the network device, and a dotted line represents a range of an auxiliary serving cell corresponding to the auxiliary carrier unit and is used for implementing data transmission between the terminal and the network device.

A wireless terminal, which may be a mobile terminal such as a mobile telephone (or "cellular" telephone), a computer, and a data card, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges language and/or data with a Radio Access Network (e.g., a Radio Access Network, RAN), may communicate with one or more core networks or the internet. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like.

Network devices 12 may include various forms of cellular base stations, home base stations, cells, wireless transmission points, macro base stations, micro base stations, relay stations, wireless access points, and so forth. In systems using different radio Access technologies, names of devices having base station functions may be different, for example, in a 3G system, the device is called a base station (Node B), in a Long Term Evolution (LTE) system, the device is called an evolved NodeB (eNB or eNodeB), in a fifth Generation mobile communication technology (5G) system, the device is called a gNB, and in a wireless local Access system, the device is called an Access point (Access point).

It should be noted that, for a 5G or New Radio Access Network (NR) system, under an NR base station (NR-NB), one or more Transmission Reception Points (TRPs) may exist, and all the TRPs belong to the same cell, where each TRP and a terminal may use the measurement reporting method described in the embodiment of the present application. In another scenario, the network device 12 may be further divided into a Central Unit (CU) and a Distributed Unit (DU), where under one CU, a plurality of DUs may exist, and each DU and the terminal may use the measurement reporting method described in this embodiment. The CU-DU separation scenario differs from the multi-TRP scenario in that the TRP is only a radio unit or an antenna device, whereas protocol stack functions, e.g. physical layer functions, may be implemented in the DU.

As communication technologies evolve, the names of network devices may change. Further, the network device 12 may be other apparatuses that provide the terminal 11 with a wireless communication function, in other possible cases.

Fig. 5 is a flowchart of a method for sending and receiving cell configuration information according to an embodiment of the present disclosure, and as shown in fig. 5, the method may include:

401. the network device determines at least one cell group.

The network device may group the plurality of cells into at least one cell group. For example, the network device may determine the at least one cell group according to some packet information configured at both ends of the network device and the terminal, and specifically, the following implementation may be implemented:

in the first mode, the network device is preconfigured with grouping information of PUCCH groups, that is, the PUCCH groups include a primary PUCCH group or a secondary PUCCH group, the primary PUCCH group refers to a cell group including a primary cell, and the secondary PUCCH group refers to a cell group including a plurality of secondary cells. Signaling to transmit the primary PUCCH group is associated with the PUCCH of the primary cell. For example, signaling comprising a primary PUCCH group is sent on the PUCCH on the primary cell. Signaling to transmit the secondary PUCCH group is associated with the PUCCH of the secondary cell. For example, signaling including the secondary PUCCH group is transmitted on the PUCCH on the secondary cell. Therefore, the network device may group a plurality of cells according to the PUCCH group, and divide the primary cell into a primary PUCCH group, where the primary PUCCH group may further include other secondary cells; the remaining secondary cells are divided into secondary PUCCH groups.

The terminal has a separate Time Advance (TA) capability for the CA, and can simultaneously receive or transmit on carriers corresponding to multiple serving cells using the same TA, where multiple serving cells are divided into one TAG; alternatively, multiple TAs may be used to receive or transmit simultaneously on carriers corresponding to multiple serving cells, which are grouped into multiple TAGs. The TAG contains a cell group in which the terminal receives or transmits using the same TA on carriers corresponding to a plurality of serving cells with the same TA. The TAG may also be referred to as an uplink synchronization group. Thus, the network device may group the plurality of cells according to the TAGs to obtain at least one cell group.

And thirdly, grouping the plurality of cells by the network equipment according to a physical characteristic to obtain at least one cell group.

For example, LTE technology is used in the unlicensed band, and based on a carrier aggregation architecture, a licensed carrier is used as a carrier of the primary cell, and a licensed carrier or an unlicensed carrier is used as a carrier of the secondary cell. The carrier corresponding to the secondary cell may be an unlicensed carrier or a licensed carrier. Assuming that the carrier corresponding to the secondary cell may be an authorized carrier, a specific LAA attribute is marked on the configuration attribute of the secondary cell during configuration, that is, the authorized carrier. In this way, the secondary cells containing the LAA attribute can be divided into the authorized carrier secondary cell group, and the secondary cells not containing the LAA attribute can be divided into the non-LAA secondary cell group. Therefore, the network device groups the cells according to the carrier characteristics of the carriers corresponding to the cells, and determines at least one cell group.

It should be understood that the physical characteristics of communication may be referred to as Numerology. The communication physical characteristics correspond to a set of different parameters employed in the communication system. The parameters for different numerologies may be different. Including, but not limited to, the physical characteristics of the communication being one or any combination of the following parameters: a subcarrier width, a Cyclic Prefix (CP) length, a Transmission Time Interval (TTI), the number of symbols (Symbol), a Resource Block (RB) position, a slot length, a frame format, and the like. The reader may understand the meaning of the communications physics Numerology by way of example from the www.3gpp.org under the proposals R1-1613779 or R2-168012, the contents of which are included in the contents of the examples of the present application. Because of the fairness and the openness of the 3GPP standards organization, further description is omitted here.

It should be noted that each cell group should include at least two cells, so that it can be shown that multiple cells correspond to the same configuration information, that is, the cell group configuration information, and for different cells, when the network device sends the configuration information to the terminal, only the same cell group configuration information needs to be sent, and there is no need to send one cell configuration information for each cell.

402. The network device sends RRC signaling to the terminal.

After the network equipment determines at least one cell group, sending RRC signaling to the terminal, wherein the RRC signaling comprises cell group configuration information of each cell group in the at least one cell group determined by the network equipment. Illustratively, the cell group configuration information includes at least one of Random Access Channel (RACH) information, Physical Random Access Channel (PRACH), Physical Downlink Shared Channel (PDSCH), Physical Uplink Shared Channel (PUSCH), Physical Hybrid automatic repeat Indicator Channel (PHICH), PUCCH, cell Uplink bandwidth information, Uplink sounding signal information, number of supported antenna layers, cross-carrier scheduling information, CSI RS, ePDCCH information, Uplink Shared Channel information, power control information for a terminal, and CQI information. It should be noted that, in the embodiment of the present application, content specifically included in the cell group configuration information is not limited, and other information may also be included in practical application, which is only an example here.

It should be noted that the RRC signaling may further include partition rule information, so that the terminal knows how the network device partitions the cell. Under the condition that the network equipment groups a plurality of cells according to a physical uplink control channel group or an uplink time advance group to obtain at least one cell group, the RRC signaling sent by the network equipment to the terminal also comprises cell group information of each cell group in the at least one cell group, and the cell group information comprises cell identification information of at least two cells contained in the cell group. The Cell identification information may be a Physical layer ID of a Cell, such as a Physical Cell Identifier (PCI), or a Cell ID, such as a Cell index. When the network equipment determines at least one cell group according to the physical characteristics, the terminal and the network equipment are determined in the same way, so that RRC signaling sent by the network equipment to the terminal does not need to include cell group information.

403. The terminal receives RRC signaling sent by the network equipment.

After the network device sends the RRC signaling to the terminal, the terminal receives the RRC signaling sent by the network device.

404. And the terminal configures each cell included in each cell group in at least one cell group according to the cell group configuration information of each cell group in at least one cell group.

After receiving an RRC signaling sent by a network device, a terminal configures each cell included in each cell group in at least one cell group, which specifically includes: and the terminal configures each cell included in the cell group according to the cell group configuration information of the cell group.

Therefore, in the method for sending and receiving cell configuration information according to the embodiment of the present application, the cells to be configured are divided to obtain at least one cell group, and each cell group corresponds to one configuration information, so that the RRC signaling sent by the network device to the terminal includes the configuration information of the cell group, and each cell included in the cell group corresponds to the same configuration information, that is, the cell group configuration information, so that the terminal can configure each cell included in the cell group according to the cell group configuration information.

Fig. 6 is a flowchart of a method for sending and receiving cell configuration information according to an embodiment of the present application, and as shown in fig. 6, the method may include:

501. and the network equipment sends the configuration information of the reference cell to the terminal.

The configuration information of the reference cell includes information for configuring the reference cell. The reference cell is a primary cell, or the reference cell is a physical uplink control channel cell in the physical uplink control information group, or the reference cell is any one of the secondary cells. It should be noted that the configuration information of the reference cell may be sent through an RRC reconfiguration message or may be sent through a handover command, which is not limited in this embodiment of the present application.

502. And the terminal receives the configuration information of the reference cell sent by the network equipment.

After the network device sends the configuration information of the reference cell to the terminal, the terminal receives the configuration information of the reference cell sent by the network device. The terminal may configure the reference cell according to the configuration information of the reference cell or may not configure the reference cell, and specifically, may be executed according to the notification of the network device.

503. The network equipment sends configuration information of each cell to be configured in at least one cell to be configured to the terminal.

The configuration information of the cell to be configured includes a first identifier, where the first identifier is used to indicate whether the configuration information of the cell to be configured is configured based on the configuration information of the reference cell, and if the first identifier indicates that the configuration information of the cell to be configured is not configured based on the configuration information of the reference cell, further, the configuration information of the cell to be configured further includes at least one second identifier, where the at least one second identifier is used to indicate whether at least one parameter in the configuration information of the cell to be configured is configured based on a parameter included in the configuration information of the reference cell, and if the second identifier indicates that a parameter corresponding to the second identifier in the configuration information of the cell to be configured is not configured based on a parameter included in the configuration information of the reference cell, the configuration information of the cell to be configured further includes a parameter corresponding to the second identifier.

For example, the following implementation manners may be used to set the first identifier and the second identifier in the configuration information of the cell to be configured.

In one possible implementation manner, as shown in (a) of fig. 7, the first identifier and the second identifier may be disposed in a header of configuration Information of the cell to be configured, where the header may be an Information Element (IE) of RRC signaling, and optionally, may be a start Information Element of the RRC signaling, that is, the first identifier and the second identifier may be disposed in the Information Element of the RRC signaling. Assuming that the first identifier is set to 1, the configuration information indicating the cell to be configured is configured based on the configuration information of the reference cell, at this time, the packet header of the configuration information of the cell to be configured does not include the second identifier, and the information unit in the configuration information of the cell to be configured does not include specific parameters either, and after the terminal receives the configuration information of the cell to be configured, and recognizes the first identifier in the packet header, it is known that the cell to be configured can be configured according to the configuration information of the reference cell. Assuming that when the first identifier is set to 0, the configuration information indicating the cell to be configured is not configured based on the configuration information of the reference cell, at this time, the packet header of the configuration information of the further cell to be configured further includes a second identifier, where the second identifier may be a character string composed of 1 and 0, and each bit of the character string from left to right sequentially corresponds to a parameter from left to right in the configuration information of the cell to be configured. In addition, the parameter corresponding to the second identifier may be that one parameter is located in one information unit, or that multiple parameters are located in the same information unit.

For a parameter located in an information unit, as shown in fig. 7(a), the first bit of the second flag corresponds to information unit 1, the second bit of the second flag corresponds to information unit 2, and the third bit of the second flag corresponds to information unit 3. Assuming that when the first bit of the second identifier is set to 1, the information unit 1 does not include a parameter, instructing the terminal to configure the cell to be configured based on the parameter corresponding to the second identifier in the configuration information of the reference cell, i.e. the parameter included in the information element 1 in the configuration information of the reference cell, configures the cell to be configured, and assuming that the second bit of the second identifier is set to 0, the information unit 2 comprises parameters for instructing the terminal to configure the cell to be configured according to the parameters corresponding to the second identifier in the configuration information of the cell to be configured, that is, the parameter included in the information element 2 in the configuration information of the cell to be configured configures the cell to be configured, and if the third bit of the second identifier is set to 1, the information unit 3 does not include the parameter, and instructs the terminal to configure the cell to be configured based on the parameter corresponding to the second identifier in the configuration information of the reference cell, that is, the parameter included in the information unit 3 in the configuration information of the reference cell configures the cell to be configured.

For a plurality of parameters located in the same information unit, it should be noted that the number of each bit of the second identifier included in the configuration information of the cell to be configured needs to be the same as the number of the parameters included in the configuration information of the reference cell, and the parameter position indicated by each bit from left to right of the character string of the second identifier should also be sequentially the same as the parameter position from left to right in the configuration information of the reference cell. As shown in (b) of fig. 7, the first bit, the second bit, and the third bit of the second identifier correspond to a parameter 1, a parameter 2, and a parameter 3 included in an information unit 1 of configuration information of a cell to be configured, respectively, and the fourth bit of the second identifier corresponds to a parameter 4 included in an information unit 2 of configuration information of a cell to be configured. Assuming that when the first bit of the second identifier is set to 1, the information unit 1 of the configuration information of the cell to be configured does not include the parameter 1, instructing the terminal to configure the cell to be configured based on the parameter corresponding to the second identifier in the configuration information of the reference cell, that is, the parameter 1 included in the information unit 1 in the configuration information of the reference cell, configuring the cell to be configured, assuming that the second bit of the second identifier is set to 1, the information unit 1 of the configuration information of the cell to be configured does not include the parameter 2, instructing the terminal to configure the cell to be configured based on the parameter corresponding to the second identifier in the configuration information of the reference cell, that is, the parameter 2 included in the information unit 1 in the configuration information of the reference cell, configuring the cell to be configured, assuming that the third bit of the second identifier is set to 0, the information unit 1 of the configuration information of the cell to be configured includes the parameter 3, instructing the terminal to configure the cell to be configured according to the parameter corresponding to the second identifier in the configuration information of the cell to be configured, that is, the parameter 3 included in the information unit 1 in the configuration information of the cell to be configured configures the cell to be configured, and if the fourth bit of the second identifier is set to 0, the information unit 2 in the configuration information of the cell to be configured includes the parameter 4, which instructs the terminal to configure the cell to be configured according to the parameter corresponding to the second identifier in the configuration information of the cell to be configured, that is, the parameter 4 included in the information unit 2 in the configuration information of the cell to be configured configures the cell to be configured.

In another possible implementation manner, the first identifier may be set in a header of the configuration information of the cell to be configured, that is, the header of the configuration information of the cell to be configured may include only the first identifier, and the second identifiers may be respectively set in information units in the configuration information of the cell to be configured. Assuming that the first identifier is set to 1, the configuration information indicating the cell to be configured is configured based on the configuration information of the reference cell, at this time, each information unit of the configuration information of the cell to be configured does not include the second identifier, and the information unit in the configuration information of the cell to be configured does not include a specific parameter either, and after the terminal receives the configuration information of the cell to be configured, and recognizes the first identifier in the packet header, it is known that the cell to be configured can be configured according to the configuration information of the reference cell. As shown in (c) of fig. 7, assuming that the first identifier is set to 0, the configuration information indicating the cell to be configured is not configured based on the configuration information of the reference cell, and at this time, each information unit of the further configuration information of the cell to be configured further includes a second identifier. Assuming that when the second identifier included in the information unit 1 of the configuration information of the cell to be configured is set to 1, the information unit 1 does not include a parameter, and instructs the terminal to configure the cell to be configured based on the parameter corresponding to the second identifier in the configuration information of the reference cell, that is, the parameter included in the information unit 1 in the configuration information of the reference cell, the information unit 2 includes a parameter, and instructs the terminal to configure the cell to be configured according to the parameter corresponding to the second identifier in the configuration information of the cell to be configured, that is, the parameter included in the information unit 2 in the configuration information of the cell to be configured, when the second identifier included in the information unit 3 of the configuration information of the cell to be configured is set to 1, the information unit 3 does not include a parameter, and instructs the terminal to configure the cell to be configured based on the parameter corresponding to the second identifier in the configuration information of the reference cell, that is, the parameter included in the information unit 3 in the configuration information of the reference cell configures the cell to be configured.

In addition, only the second identifier may be set in the information unit of the configuration information of the cell to be configured, and the parameter is carried in the information unit of the configuration information of the cell to be configured only according to the second identifier. For example, when the second identifier in the ith information element of the configuration information of the cell to be configured is set to 1, the terminal is instructed to configure the parameter based on the parameter included in the ith information element of the configuration information of the reference cell, and at this time, the specific parameter is not included in the ith information element of the configuration information of the cell to be configured. And if the second identifier in the ith information unit of the configuration information of the cell to be configured is set to be 0, indicating the terminal to configure the parameter based on the parameter included in the ith information unit of the configuration information of the cell to be configured, wherein the ith information unit of the configuration information of the cell to be configured includes a specific parameter.

It should be noted that the configuration information of the cell to be configured also includes cell identification information of the cell to be configured. And when the reference cell is one of the secondary cells, the network equipment sends the identification information of the reference cell to the terminal. For example, the cell identification information may be a physical layer ID of the cell, or may be a cell ID, such as a cell index, which is not limited in the embodiments of the present application as long as different cells can be distinguished.

504. The terminal receives configuration information of each cell to be configured in at least one cell to be configured, which is sent by the network equipment.

After the network device sends the configuration information of each cell to be configured in at least one cell to be configured to the terminal, the terminal receives the configuration information of each cell to be configured in at least one cell to be configured sent by the network device.

505. And the terminal configures the cell to be configured according to the configuration information of the cell to be configured.

After the terminal receives the configuration information of each cell to be configured in at least one cell to be configured sent by the network equipment, the terminal configures the cell to be configured corresponding to the configuration information of the cell to be configured according to the configuration information of the cell to be configured.

Firstly, the terminal identifies a first identifier, and if the first identifier indicates that the configuration information of the cell to be configured is configured based on the configuration information of the reference cell, the terminal configures the cell to be configured according to the configuration information of the reference cell. If the first identifier indicates that the configuration information of the cell to be configured is not configured based on the configuration information of the reference cell, it may be understood that the configuration information of the cell to be configured and the configuration information of the reference cell are not completely the same, that is, the configuration information of the cell to be configured and the configuration information of the reference cell may be completely different or partially different.

The terminal can identify a second identifier under the condition that the configuration information of the cell to be configured is not configured based on the configuration information of the reference cell, and if the second identifier indicates that the parameter corresponding to the second identifier is not configured based on the parameter included in the configuration information of the reference cell, the terminal configures the cell to be configured according to the parameter corresponding to the second identifier in the configuration information of the cell to be configured; and if the second identifier indicates that the parameter corresponding to the second identifier is configured based on the parameter included in the configuration information of the reference cell, the terminal configures the cell to be configured according to the parameter corresponding to the second identifier in the configuration information of the reference cell. Of course, the arrangement of the first mark and the second mark described herein may be the one shown in fig. 7(a) to 7 (c).

For example, as shown in fig. 8, the terminal configures a schematic diagram of a cell to be configured. Assuming that the cell 1 in fig. 8 is a reference cell, and the configuration information of the reference cell includes a parameter 1, a parameter 2, and a parameter 3, before the network device sends the configuration information of the cell 2 to the terminal, comparing the configuration information of the cell 2 with the configuration information of the cell 1, it can be known that the parameter 1 of the cell 2 is identical to the parameter 1 of the cell 1, the parameter 2 'of the cell 2 is not identical to the parameter 2 of the cell 1, and the parameter 3' of the cell 2 is not identical to the parameter 3 of the cell 1, the network device sets a first identifier included in the configuration information of the cell 2 to be 0, a second identifier corresponding to the parameter 1 of the cell 2 to be 1, a second identifier corresponding to the parameter 2 of the cell 2 to be 0, a second identifier corresponding to the parameter 3 of the cell 2 to be 0, and the configuration information of the cell 2 sent by the network device to the terminal does not include the parameter 1 of the cell 2, parameters 2 'and 3' of cell 2 need to be included. After the terminal receives the configuration information of the cell 2 sent by the network equipment, the terminal identifies that the first identifier is 0, at this time, the terminal learns that the configuration information of the cell 2 is not configured based on the configuration information of the reference cell, the terminal identifies that the second identifier corresponding to the parameter 1 of the cell 2 is set to be 1, at this time, the terminal receives that an information unit including the parameter 1 of the cell 2 is empty and does not receive any information, and the terminal identifies the parameter corresponding to the second identifier according to the configuration information of the reference cell; the terminal identifies that the second identifier corresponding to the parameter 2 ' of the cell 2 is 0, and at this time, the terminal receives the parameter 2 ' of the cell 2 and configures the parameter 2 ' of the cell 2; the terminal identifies that the second identifier corresponding to the parameter 3 of the cell 2 is 0, and at this time, the terminal receives the parameter 3 'of the cell 2 and configures the parameter 3' of the cell 2. Similarly, before the network device sends the configuration information of the cell 3 to the terminal, the configuration information of the cell 3 is compared with the configuration information of the cell 1, and it can be known that the parameter 1 of the cell 3 is completely the same as the parameter 1 of the cell 1, the parameter 2 of the cell 3 is completely the same as the parameter 2 of the cell 1, and the parameter 3 of the cell 3 is completely the same as the parameter 3 of the cell 1, then the network device may set the first identifier included in the configuration information of the cell 3 to 1, the configuration information of the cell 3 does not include the second identifier, and the configuration information of the cell 3 sent by the network device to the terminal does not include any parameter. After the terminal receives the configuration information of the cell 3 sent by the network device, the terminal identifies that the first identifier is 1, at this time, the terminal learns that the configuration information of the cell 3 is configured based on the configuration information of the reference cell, and the terminal directly configures the cell 3 according to the configuration information of the reference cell.

It should be noted that the same parameter may be system bandwidth, PHICH information, Physical Downlink Control Channel (PDCCH) information, and numerology information, and the different parameters may be power Control parameter, antenna parameter, and center frequency information parameter, and the like.

Therefore, in the method for sending cell configuration information according to the embodiment of the present application, the network device sets the first identifier in the configuration information of the cell to be configured to indicate whether a parameter included in the configuration information of the cell to be configured is the same as a parameter included in the configuration information of the reference cell, and reduces the overhead of the configuration signaling when the cell is configured by reducing the same parameter included in the configuration signaling sent to the terminal when the parameter included in the configuration information of the cell to be configured is the same as the parameter included in the configuration information of the reference cell.

The above-mentioned scheme provided by the embodiment of the present application is introduced mainly from the perspective of interaction between network elements.
