[0039] The communication systems to which the embodiments of the present application are applicable include, but are not limited to, Long Term Evolution (LTE) systems, fifth-generation (5G) systems, new wireless (NR) systems, and future evolution systems or multiple communication fusion systems. Among them, the 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The technical solution of the present application is also applicable to different network architectures, including but not limited to relay network architectures, dual-connection architectures, vehicle-to-everything communication architectures, and other architectures.

[0040] This application mainly relates to the communication between terminal equipment and network equipment. Among them:

[0041] The network device in the embodiment of the present application may also be referred to as an access network device, for example, it may be a base station (BS) (also referred to as a base station device), and the network device is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in the second-generation (2G) network, the equipment that provides base station functions includes the base transceiver station (BTS), in the third-generation (3G) network, the equipment that provides base station functions includes the node B (NodeB), and in the fourth-generation (4G) network, the equipment that provides base station functions includes the evolved node B (eNB). In wireless local area networks (WLAN), the equipment that provides base station functions is the access point (AP), and the equipment that provides base station functions in NR is the next generation Node Base station (gNB), as well as the evolved node B (ng-eNB), where the gNB and the terminal device communicate using NR technology, and the ng-eNB and the terminal device communicate using evolved universal terrestrial radio access (Evolved Universal Terrestrial Radio Access, E-UTRA) technology, and both gNB and ng-eNB can be connected to the 5G core network. The network devices in the embodiments of the present application also include devices that provide base station functions in future new communication systems, etc.

[0042] The terminal equipment in the embodiments of the present application may refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (Mobile Station, MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents or user devices. The terminal equipment may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolving Public Land Mobile Network (PLMN), etc., which is not limited in the embodiments of the present application. The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.

[0043] As described in the background art, when there are multiple non-anchor cells, how to configure and transmit SIB1 of the non-anchor cells is a technical problem that needs to be solved urgently.

[0044] Specifically, how the anchor cell configures the SIB1 of the non-anchor cell and how the terminal device receives the SIB1 of the non-anchor cell in the anchor cell are issues that need to be resolved.

[0045] In the technical solution of the present application, the network device configures and sends the first information, which not only enables the terminal device to receive the SIB1 of multiple non-anchor cells, but also enables the terminal device to know which non-anchor cells' SIB1 is received, thereby realizing the smooth transmission of SIB1 of some non-anchor cells on the anchor cell and reducing the power consumption of the non-anchor cells.

[0046] Specifically, in the current network, in order to ensure the experience of the terminal device, the network equipment is always in working state or semi-sleeping state, and cannot be completely shut down or counted into deep sleep mode. In the 5G network, due to the large number of spectrum resources, such as 1GHz, 2GHz, 4GHz, 6GHz and 26GHz bands, when the network load is low, some frequency bands (such as 4GHz, 6GHz or 26GHz, etc.) corresponding to the carrier (carrier) or cell (cell) can be turned off as much as possible, and turned on as needed to achieve the purpose of network energy saving. In other words, when the network load is low, some carriers or cells do not need to carry data. Generally speaking, the purpose of network energy saving can be achieved by switching certain carriers, but this generally needs to be achieved when the network load is low.

[0047] In a heterogeneous network, in order to reduce the static power consumption of non-anchor cells, anchor cells can send part of the SIB1 of non-anchor cells to terminal devices. In this scenario, non-anchor cells do not need to send SIB1, thereby achieving the purpose of energy saving.

[0048] In this embodiment, when the carriers or cells corresponding to some frequency bands (such as 4GHz, 6GHz or 26GHz, etc.) are turned off, these carriers or cells still need to send measurement reference signals to support the access and mobility of terminal devices. Such carriers or cells can be called non-anchor carriers or non-anchor cells, or second-class carriers or second-class cells, or secondary carriers or secondary cells (SCell). Relatively speaking, carriers or cells that are not turned off can be called anchor carriers or anchor cells, or first-class carriers or first-class cells, or primary carriers or primary cells (PCell).

[0049] Generally speaking, non-anchor cells are deployed within the coverage area of ​​anchor cells. Anchor cells provide wide coverage, while non-anchor cells have a smaller coverage area and provide high-speed data transmission services. Non-anchor cells are controlled by the network and can be opened on demand, such as Figure 1As shown. The non-anchor cell may be different from the secondary cell in carrier aggregation (CA) or dual connection (DC), and the non-anchor cell may be the primary cell or the primary secondary cell (PSCell) in CA or DC. Specifically, the anchor cell is the primary cell or the primary secondary cell in CA or DC. Therefore, the switch between the non-anchor cell and the anchor cell may be the switch between the primary cell or the primary secondary cell. If the non-anchor cell is a secondary cell in CA or DC, then the switch between the non-anchor cell and the anchor cell may be the addition, deletion or modification of the secondary cell in CA or DC. The anchor cell and the non-anchor cell have low requirements on the backhaul network (backhaul), and do not require the terminal device to receive signals of multiple carriers at the same time, which is easier to implement.

[0050] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0051] See also Figure 2 The method provided in this application specifically includes the following steps:

[0052] Step 201: The terminal device receives first information on an anchor cell, wherein the first information includes system information blocks SIB1 of multiple non-anchor cells.

[0053] It is understandable that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated inside a chip or a chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0054] The application scenario of this embodiment is a multi-carrier deployment scenario. The non-anchor cell is deployed within the coverage area of ​​the anchor cell. The anchor cell provides a large coverage area, while the non-anchor cell has a smaller coverage area and provides high-speed data transmission services. The non-anchor cell is controlled by the network and can be opened on demand.

[0055] Specifically, Figure 2 The network device shown may be a network device to which an anchor cell belongs. The network device sends the first information on the anchor cell, and correspondingly, the terminal device receives the first information on the anchor cell.

[0056] In this embodiment, when there are multiple non-anchor cells within the coverage of the anchor cell, the terminal device can receive the non-anchor cell identifier in addition to the SIB1 of the non-anchor cell on the anchor cell. The identifier of the non-anchor cell corresponds to the SIB1 of the non-anchor cell one by one, that is, the SIB1 of each non-anchor cell corresponds to the identifier of the non-anchor cell.

[0057] In a specific implementation, a list may be used to indicate the identifiers of multiple non-anchor cells and their corresponding SIB1s.

[0058] In a non-limiting embodiment, the terminal device may receive a first system message on an anchor cell, and the first information is carried in the first system message. The first system message is a newly added system message block of the anchor cell.

[0059] In this embodiment, a new system information block SIBX is introduced, and the system information block SIBX includes the first information. The newly added system information block SIBX of the anchor cell is used to transmit the first information.

[0060] In another non-limiting embodiment, the terminal device may receive a first system message, and the first information is carried in the first system message. The first system message is another system message block of the anchor cell.

[0061] In this embodiment, the first information is carried in the SIB1 of the anchor cell or other system information blocks. The terminal device receives the SIB1 of the non-anchor cell while receiving the SIB1 or other system information blocks.

[0062] Specifically, the SIB1 of the non-anchor cell may carry one or more of the following information:

[0063] - Random access related configuration, such as PRACH configuration;

[0064] -Paging related configuration.

[0065] It should be noted that the specific content of SIB1 of the non-anchor cell can refer to the existing technology, and this application does not limit this.

[0066] When the measured target cell meets the cell reselection criteria, that is, the reference signal receiving power (RSRP) of the target cell is greater than the threshold, the terminal device will stay on the target cell, that is, receive the SIB1 of the target cell to obtain relevant configuration information. On this basis, the terminal device can optimize the behavior of receiving the SIB1 of the non-anchor cell in the anchor cell to avoid invalid reception of the SIB1 of the non-anchor cell.

[0067] Embodiment 1: In response to a non-anchor cell being located in the non-anchor cell list and a signal quality of the non-anchor cell satisfying a first condition, a terminal device starts receiving first information.

[0068] Please refer to Figure 3In step 301, the network device sends second information to the terminal device on the anchor cell. The second information includes a non-anchor cell list, and the non-anchor cell list includes identifiers of multiple non-anchor cells.

[0069] In step 302, the terminal device performs discovery and measurement of non-anchor cells. In other words, the terminal device performs neighboring cell measurement.

[0070] Through step 302, the terminal device can obtain the signal quality of multiple non-anchor cells. The signal quality can be specifically in the form of RSRP, Reference Signal Receiving Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), etc.

[0071] In this case, in step 303, the terminal device determines whether the discovered non-anchor cell is in the non-anchor cell list and whether the signal quality of the non-anchor cell meets the first condition, wherein the first condition indicates that the reference signal quality of the non-anchor cell is less than or not greater than a threshold.

[0072] In a specific implementation, the threshold in the first condition may be received by the terminal device from the anchor cell. Specifically, the terminal device receives first configuration information on the anchor cell, and the first configuration information includes the threshold. The first configuration information may be carried in any implementable downlink information such as system information and high-layer signaling.

[0073] In another optional embodiment, the threshold in the first condition may be received by the terminal device from a non-anchor cell. Specifically, the terminal device receives second configuration information on the non-anchor cell, and the second configuration information includes the threshold. The second configuration information may be carried in any implementable downlink information such as system information and high-layer signaling.

[0074] It should be noted that the above thresholds are also specified by the communication standard protocol, and this application does not impose any restrictions on this.

[0075] When the non-anchor cell is in the non-anchor cell list and the signal quality of the non-anchor cell satisfies the first condition, in step 304, the terminal device starts receiving the first information.

[0076] Specifically, the terminal device starts to receive the first information means that the terminal device starts to monitor the physical downlink control channel (Physical Downlink Control Channel, PDCCH) corresponding to the first message.

[0077] For example, when the first information is carried in a newly added system message block SIBX of the anchor cell, the terminal device starts PDCCH monitoring corresponding to the SIBX.

[0078] For another example, when the first information is carried in SIB1 of the anchor cell, the terminal device starts PDCCH monitoring corresponding to SIB1.

[0079] In this embodiment, in this way, the terminal device can determine the time point to start receiving the non-anchor cell SIB1, thereby avoiding receiving invalid non-anchor cell SIB1.

[0080] Embodiment 2: In response to a non-anchor cell being in a non-anchor cell list, a signal quality of the non-anchor cell satisfying a first condition, and a first indication message being received, the terminal device starts receiving first information.

[0081] Please refer to Figure 4 In step 401, the terminal device receives second information sent by the anchor cell. The second information includes a non-anchor cell list, and the non-anchor cell list includes identifiers of multiple non-anchor cells. The anchor cell is Figure 4 The cells within the coverage range of the network equipment shown in .

[0082] In step 402, the terminal device performs discovery and measurement of non-anchor cells. In other words, the terminal device performs neighboring cell measurement.

[0083] Through step 402, the terminal device can obtain the signal qualities of multiple non-anchor cells.

[0084] In step 403, the network device sends first indication information to the terminal device, wherein the first indication message indicates whether to receive SIB1 of a non-anchor cell.

[0085] In a specific embodiment, the first indication message is carried in the downlink control information (DCI) or paging early indication (PEI) of the anchor cell for scheduling the paging message. That is, a bit can be added to the above DCI or PEI, and the value of the bit indicates receiving the SIB1 of the non-anchor cell or not receiving the SIB1 of the non-anchor cell.

[0086] Specifically, when the anchor cell is not configured with PEI, 1 bit of information is set in the paging DCI to indicate whether the terminal device starts receiving SIB1 corresponding to the non-anchor cell. When the anchor cell is configured with PEI, 1 bit of information is set in the PEI to indicate whether the terminal device starts receiving SIB1 corresponding to the non-anchor cell.

[0087] In another specific embodiment, the first indication message is carried in the system information block SIB of the anchor cell. Specifically, the activation / deactivation information may be carried in the system information block SIB of the anchor cell to activate / deactivate the reception of the SIB1 corresponding to the non-anchor cell.

[0088] In this embodiment, by setting the first indication message, the anchor cell can take the network load into consideration. When the load is low, the first indication message is used to instruct the terminal device to receive the SIB1 of the non-anchor cell. When the load is high, the first indication message is used to instruct the terminal device not to receive the SIB1 of the non-anchor cell.

[0089] In step 404, the terminal device determines whether the discovered non-anchor cell is in the non-anchor cell list, whether the signal quality of the non-anchor cell meets the first condition, and whether the first indication message indicates receiving the SIB1 of the non-anchor cell.

[0090] When the non-anchor cell is in the non-anchor cell list, the signal quality of the non-anchor cell satisfies the first condition, and the first indication message indicates receiving SIB1 of the non-anchor cell, in step 405, the terminal device starts receiving the first information.

[0091] For example, the terminal device finds that the RSRP corresponding to a non-anchor cell is greater than a threshold, the SIB1 corresponding to the non-anchor cell is sent by the anchor cell, and the network device instructs the terminal device to start SIB1 reception of the non-anchor cell, then the terminal device starts SIBX reception on the anchor cell, that is, the terminal device starts PDCCH monitoring corresponding to SIBX.

[0092] It should be noted that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.
