Abstract
Description
Technical Field
[0001] The present application relates to the field of communications, and more particularly, to an information indication method and a communication device. Background Art
[0002] Reduced capability user equipment (UE) refers to terminal equipment that has lower requirements for service rate and latency, but instead focuses on cost control. That is, reduced capability UEs do not require strong hardware capabilities. Compared with legacy UEs, the number of receiving antennas, operating bandwidth, and processing time are all reduced.
[0003] Low-capability terminal devices can be divided into terminal devices with 1 receiving antenna (abbreviated as 1RUE in this application) and terminal devices with 2 receiving antennas (abbreviated as 2RUE in this application) according to the number of receiving antennas. Because 1RUE has fewer receiving antennas, its coverage is worse than that of 2R UE and 4R UE. Here, 4R UE refers to an ordinary terminal device with 4 receiving antennas. Figure 1 As shown in the figure, the coverage of cell #1 served by the base station is represented by the larger solid circle on the outside, the coverage of 4R UEs (i.e., the range where data can be transmitted normally) is represented by the larger dashed circle on the inside, and the coverage of 1R UEs is represented by the smaller solid circle on the inside. Therefore, if you want 1R UEs outside the inner solid circle and within the dashed circle to receive data normally like 4R UEs, the base station needs to perform coverage enhancement for 1R UEs.
[0004] In one technique, the base station can indicate whether the 1R UE can camp on cell #1 through the system information block (SIB) 1. However, in this method, if Figure 1 The base station in the example is a base station that does not support coverage enhancement. When the base station indicates that all 1R UEs can reside in cell #1, in this case, if some 1R UEs are located in Figure 1 Outside the inner solid circle and inside the dotted circle, the 1R UE cannot receive data normally after camping because the base station does not support coverage enhancement; when the base station instructs 1R UEs not to camp on cell #1, in this case, if some 1R UEs are located Figure 1 Within the inner solid coil (i.e., the center of cell #1), the base station does not need to perform coverage enhancement for 1R UEs. Since the base station instructs 1R UEs not to reside in cell #1, the base station will also prohibit these 1R UEs from residing in cell #1. That is, the 1R UEs in the center of cell #1 cannot normally reside in this cell. Summary of the Invention
[0005] The present application provides an information indication method and communication device, which uses a single UE as the granularity. The UE can determine whether the network device allows the UE to reside or whether the UE can receive data normally through the RSRP threshold, which can save the UE's power consumption and time.
[0006] In a first aspect, a method for information indication is provided. The method can be executed by a terminal device, or can also be executed by a chip or circuit provided in the terminal device. This application is not limited to this. For ease of description, the following description is based on the example of execution by a terminal device. The method includes: the terminal device receiving a first message from a network device; the terminal device determining whether it is allowed to reside in a first cell based on whether the first message includes a reference signal received power (RSRP) threshold.
[0007] In the above technical solution, compared with Figure 1 In the case where a network device that does not support coverage enhancement directly indicates whether a certain type of UE can reside in the first cell, it may cause a UE that can reside in cell #1 to be instructed not to reside in cell #1, or cause a UE that cannot reside in cell #1 to be unable to receive data normally after residing in the cell. In this way, the UE that cannot reside in cell #1 and cannot receive data normally will continue to select a new cell to reside in, wasting the UE's power consumption and time. The solution proposed in this application uses a single UE as the granularity. The UE can accurately determine whether it can reside in the first cell or whether it can receive data normally through the RSRP threshold in the first message. This can avoid the problem of some UEs having to select a cell again due to direct instructions, saving the UE's power consumption and time.
[0008] In combination with the first aspect, in certain implementations of the first aspect, when the first message includes an RSRP threshold, when the RSRP value of the terminal device is less than the RSRP threshold, the terminal device is not allowed to reside in the first cell; when the RSRP value of the terminal device is greater than the RSRP threshold, the terminal device is allowed to reside in the first cell; when the RSRP value of the terminal device is equal to the RSRP threshold, the terminal device is allowed to reside in the first cell, or the terminal device is not allowed to reside in the first cell.
[0009] In combination with the first aspect, in certain implementations of the first aspect, when the first message includes an RSRP threshold, the terminal device is allowed to reside in the first cell; when the RSRP value of the terminal device is less than the RSRP threshold, the terminal device cannot normally receive data sent by the network device; when the RSRP value of the terminal device is greater than the RSRP threshold, the terminal device can normally receive data sent by the network device; the RSRP value of the terminal device is equal to the RSRP threshold, the terminal device cannot normally receive data sent by the network device, or the terminal device can normally receive data sent by the network device.

[0014] In combination with the first aspect, in certain implementations of the first aspect, the first message is a system information block SIB1 message corresponding to the first cell.
[0015] In a second aspect, a method for information indication is provided. The method for information indication can be performed by a network device, or can also be performed by a chip or circuit provided in the network device. This application is not limited to this.

[0024] The above technical solution is applicable to both the initial cell selection and the cell switching. Here, the main explanation is about the situation applicable to the initial cell selection. When the UE is prohibited from residing in the first cell during the initial cell selection, the UE can, based on the neighboring cell information that supports or does not support the UE configured by the network device in the first message, not receive the broadcast information of the neighboring cells that do not support the UE, or only receive the broadcast information of the neighboring cells that support the UE, or reduce the number of times the UE performs blind cell selection based on the neighboring cell information that supports and does not support the UE, so that the UE can find a suitable cell to reside in more quickly, thereby saving UE power consumption and cell selection time.
[0025] In combination with the third aspect, in some implementations of the third aspect, the third type of terminal device is a terminal device with two receiving antennas, and / or a terminal device with one receiving antenna.
[0026] In combination with the third aspect, in certain implementations of the third aspect, the first message also includes second indication information, and the second indication information is used to indicate one or more third cells that support or do not support the second type of terminal device to reside, the third cell is a neighboring cell of the first cell, and the second type of terminal device and the third type of terminal device are different types of terminal devices.

[0036] In the above technical solution, when the UE performs cell switching (or cell reselection), the UE will only read the relevant SIB messages according to the first indication information, which allows the UE to read less of the SIB messages in some cases, instead of reading all the SIB messages about cell reselection, thereby saving UE power consumption and cell selection time; when the UE performs initial cell selection, the UE can read the relevant SIB messages instead of not reading all the SIB messages and performing blind cell selection, thereby reducing the number of blind cell selections and saving UE power consumption and cell selection time.

The terminal device in the wireless communication system (PLMN) and / or any other suitable device for communicating on the wireless communication system is not limited in the embodiments of the present application.
[0075] Wearable devices, also known as wearable smart devices, are a general term for wearable devices that use wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include those that are fully functional, large in size, and can achieve full or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.
[0076] In addition, in the embodiments of the present application, the terminal device can also be a terminal device in the Internet of Things system. IoT is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection.
[0077] In addition, in an embodiment of the present application, the terminal device may also include sensors such as smart printers, train detectors, and gas stations. Its main functions include collecting data (part of the terminal device), receiving control information and downlink data from the network device, and sending electromagnetic waves to transmit uplink data to the network device.
[0078] The network device in the embodiment of the present application can be a device for communicating with a terminal device. The network device can be an evolved nodeB (eNB or eNodeB) in an LTE system, a wireless controller in a cloud radio access network (CRAN) scenario, a radio network controller (RNC), a base station controller (BSC), a home base station (for example, home evolved nodeB, or home nodeB, HNB), a baseband unit (BBU), or the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a future 5G network, or a network device in a future evolved PLMN network, etc., can be an access point (AP) in a wireless local area network (WLAN), a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc., can be a new wireless system (new The gNB or transmission point (TRP or TP) in a 5G radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or transmission point, such as a baseband unit (BBU) or a distributed unit (DU), etc., is not limited in the embodiments of the present application.
[0079] In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. The AAU implements some physical layer processing functions, RF processing, and active antenna-related functions. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can also be considered to be sent by the DU, or by both the DU and the AAU. It is understood that a network device can be a device that includes one or more of a CU node, a DU node, or an AAU node. In addition, the CU may be divided into a network device in an access network (radio access network, RAN), or may be divided into a network device in a core network (core network, CN), which is not limited in this application.
[0080] In addition, in an embodiment of the present application, the network device provides services for the cell, and the terminal device communicates with the cell through the transmission resources (for example, frequency domain resources, or spectrum resources) allocated by the network device. The cell may belong to a macro base station (for example, a macro eNB or a macro gNB, etc.), or may belong to a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.
[0081] In addition, in an embodiment of the present application, the network device may include a base station (gNB), such as a macro base station, a micro base station, an indoor hotspot, and a relay node, etc., whose function is to send radio waves to the terminal device to realize downlink data transmission on the one hand, and to send scheduling information to control uplink transmission on the other hand, and to receive radio waves sent by the terminal device and receive uplink data transmission.
[0082] In order to better understand the embodiments of the present application, the concepts involved in the embodiments of the present application are first introduced below.
[0083] 1. Synchronization signal block (SSB): Contains primary / secondary synchronization signals and the physical broadcast channel (PBCH), providing UEs with cell downlink synchronization and basic cell configuration information. The PBCH carries the cell's master information block (MIB), which indicates whether SIB1 exists and its location.
[0084] 2. Cell Barred: Cell barring is a method used by the network to control load. When the network load is heavy, the network can control the UE not to reside in a certain cell. The cell barred IE, which indicates the cell residence of standard (legacy) UEs, is broadcast to the UE via MIB messages. However, only one bit is available in the MIB. Therefore, the cell barred IE for low-capability UEs can be carried in SIB1 to indicate whether the cell barred IE is allowed to reside in the cell. This method allows the base station to more flexibly indicate whether legacy UEs and low-capability UEs are allowed to reside in the cell.
[0085] It should be understood that when the UE is prohibited from camping during initial cell selection, the UE will not read other SIB messages (SIB2, 3, 4, etc.), but the cell reselection parameters are included in these SIB messages, so the UE will not read the cell reselection parameters and perform blind cell selection.
[0086] It should also be understood that when a low-capability UE successfully resides in a certain service cell and wants to switch to the target cell, because the low-capability UE has successfully resided in the service cell, it can read its cell reselection-related SIB messages (such as SIB2, 3, 4, etc.). At this time, the UE can perform cell reselection based on the parameters in the relevant SIB messages.
[0087] 3. Information contained in SIB2 to SIB5:
[0088] SIB2 contains public information related to intra-frequency, inter-frequency and / or inter-system cell reselection;
[0089] SIB3 contains neighboring cell related information only related to intra-frequency cell reselection. The IE includes cells with specific reselection parameters and blacklisted cells.
[0090] SIB4 contains information related only to inter-frequency cell reselection, that is, information about other NR frequencies and inter-frequency neighboring cells related to cell reselection.
[0091] SIB5 contains only information related to inter-system cell reselection, ie, information of evolved universal terrestrial radio access (E-UTRA) frequencies and E-UTRA neighboring cells related to cell reselection.
[0092] The information indication method proposed in this application is described in detail below.
[0093] See also Figure 3 , Figure 3 It is a schematic flow chart of an information indication method proposed in this application.
[0094] S301: A network device determines a first message, where the first message indicates whether a UE receiving the first message is allowed to reside in a first cell by including a reference signal received power (RSRP) value.
[0095] When the first message includes the RSRP threshold, it can be expressed in the following two ways:
[0096] (1) When the first message includes an RSRP threshold, if the RSRP value of the UE is less than the RSRP threshold, the UE is not allowed to reside in the first cell; if the RSRP value of the UE is greater than the RSRP threshold, the UE is allowed to reside in the first cell; if the RSRP value of the UE is equal to the RSRP threshold, the UE is allowed to reside in the first cell, or the UE is not allowed to reside in the first cell.
[0097] (2) When the first message includes an RSRP threshold, the UE is allowed to reside in the first cell regardless of its RSRP value. If the UE's RSRP value is less than the RSRP threshold, the UE cannot normally receive data sent by the network device; if the UE's RSRP value is greater than the RSRP threshold, the UE can normally receive data sent by the network device; if the UE's RSRP value is equal to the RSRP threshold, the UE cannot normally receive data sent by the network device, or the UE can normally receive data sent by the network device.
[0098] When the first message does not include the RSRP threshold, it may indicate that the UE is not allowed to camp on the first cell.
[0099] Optionally, the first message also includes first indication information, and the first indication information is used to indicate whether the first type terminal device is allowed to reside in the first cell. It should be noted that the UE that determines whether it can reside in the first cell through the RSRP threshold can be understood as a second type terminal device, wherein the first type terminal device and the second type terminal device are different types of terminal devices. Specifically, the first type terminal device and the second type terminal device are terminal devices with different capabilities. As an example, in this embodiment, the first type terminal device is a 2R UE, and the second type terminal device is a 1R UE.
[0100] Optionally, when the first message does not include the first indication information, the first type of terminal device is not allowed to reside in the first cell.
[0101] Optionally, the first message is a SIB1 message corresponding to the first cell.
[0102] In a possible specific implementation, the network device may add a new cellbarred IE for the low-capability UE in SIB1 (i.e., an example of the first message), such as Cellbarred-redcap indication (i.e., an example of the first indication information), to indicate whether the 2R UE is allowed to reside, and when sending the Cellbarred-redcap indication, carry an RSRP threshold to indicate whether the 1R UE is allowed to reside or whether it can receive data normally.
[0103] It can be seen that compared with the method of using two indication messages to indicate whether 1R UE and 2R UE are allowed to reside, this implementation method only uses one indication message, that is, the UE can indicate whether 1R UE and 2R UE are allowed to reside by carrying an RSRP threshold in one indication message, thereby saving signaling overhead.
[0104] S302: The network device sends a first message.
[0105] Optionally, the network device broadcasts the first message to UEs in the first cell.
[0106] Correspondingly, the UE receives the first message.
[0107] S303: The UE determines whether it is allowed to camp on the first cell according to whether the first message includes a reference signal received power (RSRP) threshold.
[0108] Regarding whether the UE is allowed to camp on the first cell, please refer to the description in S301 and will not be repeated here.
[0109] It can be seen that compared with Figure 1In the case where a network device that does not support coverage enhancement directly indicates whether a certain type of UE can reside in the first cell, it may cause a UE that can reside in cell #1 to be instructed that it cannot reside in cell #1, or cause a UE that cannot reside in cell #1 to be unable to receive data normally after residing in the cell. In this way, the UE that cannot reside in cell #1 and cannot receive data normally will continue to select a new cell to reside in, wasting the UE's power consumption and time. The solution proposed in this application uses a single UE as the granularity. The UE can accurately judge whether it can reside in the first cell or whether it can receive data normally through the RSRP threshold in the first message, which can avoid the problem of some UEs selecting cells again due to direct instructions, thereby saving the UE's power consumption and time. At the same time, compared with the method of indicating whether 1R UE and 2R UE are allowed to reside through two indication messages, signaling overhead is saved.
[0110] In one implementation, when a UE performs initial cell selection, it is not allowed to camp on the first cell. The UE will perform blind cell selection and reselect another cell to camp on. As previously mentioned, when the UE is prohibited from camping on the cell during initial cell selection, the UE will not read other SIB messages (SIB2, 3, 4, etc.). However, the cell reselection parameters are included in these SIB messages, so the UE will not read the cell reselection parameters and perform blind cell selection. However, the UE may select a cell that does not support UE camping, wasting power consumption and time for low-capability UEs.
[0111] In view of this, the present application proposes another information indication method, which can reduce the number of blind cell selections of UEs and enable low-capability UEs to find a suitable cell to reside in more quickly.
[0112] See also Figure 4 , Figure 4 It is a schematic flow chart of another information indication method proposed in this application.
[0113] S401, the network device determines a first message, the first message includes first indication information, the first indication information is used to indicate one or more second cells that support or do not support the third type of terminal device to reside, and the second cell is a neighboring cell of the first cell.
[0114] Optionally, the third type of terminal device may be a 2R UE and / or a 1R UE. When the third type of terminal device is a 2R UE, it may be understood that the first indication information is used to indicate one or more second cells that support or do not support the 2R UE's residency; when the third type of terminal device is a 1R UE, it may be understood that the first indication information is used to indicate one or more second cells that support or do not support the 1R UE's residency; when the third type of terminal device is a 1R UE and a 2R UE, it may be understood that the first indication information is used to indicate one or more second cells that support or do not support the 2R UE's residency, and the first indication information is also used to indicate one or more second cells that support or do not support the 1R UE's residency.
[0115] Optionally, when the third-type terminal device indicates only one type of terminal device, the first message may further include second indication information, where the second indication information is used to indicate one or more third cells that support or do not support the second-type terminal device, where the third cell is a neighboring cell of the first cell, and the second-type terminal device and the third-type terminal device are different types of terminal devices. As an example, the third-type terminal device is a 2R UE, and the second-type terminal device is a 1R UE.
[0116] Optionally, the first message is a SIB1 message corresponding to the first cell.
[0117] In a possible specific implementation, the network device may add a neighboring cell list (ie, redcap-supported / redcap-unsupported list) that supports or does not support low-capability UEs in SIB1 (ie, an example of the first message) (ie, an example of the first indication information).
[0118] Optionally, the above-mentioned neighbor cell list that supports or does not support low-capability UEs can be a neighbor cell list that supports or does not support all low-capability UEs, or can be a neighbor cell list that partially supports or does not support low-capability UEs.
[0119] S402: The network device sends a first message.
[0120] Optionally, the network device broadcasts the first message to UEs in the first cell.
[0121] Correspondingly, the UE receives the first message, wherein the UE is a third type of terminal device.
[0122] S403: When the UE performs cell handover in the first cell or when the UE is prohibited from camping on the first cell, the UE reselects a cell to camp on according to the first indication information.
[0123] The above technical solution is applicable to both the initial cell selection and the cell switching. Here, the main explanation is about the situation applicable to the initial cell selection. When the UE is prohibited from residing in the first cell during the initial cell selection, the UE can, based on the neighboring cell information that supports or does not support the UE configured by the network device in the first message, not receive the broadcast information of the neighboring cells that do not support the UE, or only receive the broadcast information of the neighboring cells that support the UE, or reduce the number of times the UE performs blind cell selection based on the neighboring cell information that supports and does not support the UE, so that the UE can find a suitable cell to reside in more quickly, thereby saving UE power consumption and cell selection time.
[0124] In another implementation, if the UE has successfully resided in the first cell and wants to switch to the target cell, when the UE performs cell reselection, since the network device adds a list of neighboring cells that support the UE in the SIB messages related to cell reselection (such as SIB2, 3, 4, etc.), the UE needs to read all the SIB messages related to cell reselection to determine which neighboring cells support the UE's residence, which wastes the UE's power consumption and time.
[0125] In view of this, the present application proposes another information indication method, which can enable the UE to find a suitable cell to camp on more quickly.
[0126] See also Figure 5 , Figure 5 This is a schematic flow chart of another information indication method proposed in this application.
[0127] S501, the network device determines a first message, the first message includes first indication information, the first indication information is used to instruct the UE to read one or more messages in the SIB message about cell reselection corresponding to the first cell when the UE performs cell switching in the first cell or when the UE is prohibited from staying in the first cell, and the one or more messages include neighboring cell information supporting the UE.
[0128] Optionally, if the SIB message corresponding to the first cell regarding cell reselection contains a same-frequency neighboring area that supports the UE, but does not contain an inter-frequency neighboring area that supports the UE, the first indication information is used to instruct the UE to read the SIB message corresponding to the first cell containing the same-frequency neighboring area information that supports the UE. As an example, the first indication information instructs the UE to read only the SIB2 and / or SIB3 messages, without reading other irrelevant SIB messages involving cell reselection such as SIB4. It can be understood that the first indication information in this example also indirectly indicates that none of the inter-frequency neighboring areas of the first cell support UE residency.
[0129] Optionally, if there are inter-frequency neighboring cells that support the UE in all SIB messages about cell reselection corresponding to the first cell, but there are no same-frequency neighboring cells that support the UE, the first indication information is used to instruct the UE to read the SIB message corresponding to the first cell containing the information of inter-frequency neighboring cells that support the UE. As an example, the first indication information instructs the UE to read only SIB2 and / or SIB4 messages, without reading other irrelevant SIB messages involving cell reselection such as SIB3. It can be understood that the first indication information in this example also indirectly indicates that none of the same-frequency neighboring cells of the first cell support UE residency.
[0130] Optionally, the first message is a SIB1 message corresponding to the first cell.
[0131] In one possible specific implementation, the network device may add a new IE, Related-SI indication (i.e., an example of the first indication information), for the UE in SIB1 (i.e., an example of the first message). When the UE performs cell reselection, the UE will read the necessary SIB messages based on this IE instead of reading all SIB messages related to cell reselection.
[0132] Optionally, the first message may not include the first indication information, which may indicate the following two situations:
[0133] (1) Indicates that the SIB message regarding cell reselection corresponding to the first cell contains information about the same-frequency and different-frequency neighboring cells that support the UE. The UE reads all SIB messages regarding cell reselection corresponding to the first cell normally according to the existing process.
[0134] (2) Indicates that the SIB message regarding cell reselection corresponding to the first cell does not contain neighboring cell information supporting the UE, and the UE does not need to read the SIB message regarding cell reselection corresponding to the first cell.
[0135] S502: The network device sends a first message.
[0136] Exemplarily, the network device broadcasts a first message to UEs in a first cell.
[0137] Correspondingly, the UE receives the first message.
[0138] S503: When the UE performs cell handover in the first cell or when the UE is prohibited from camping on the first cell, the UE reads one or more messages in the SIB message about cell reselection corresponding to the first cell according to the first indication information.
[0139] Optionally, the first message may not include the first indication information. For how the UE reads the SIB message about cell reselection, refer to the description in S501 and will not be repeated here.
[0140] Optionally, the UE in this embodiment may be a low-capability terminal device or a common UE, and this application does not make any specific limitation on this.
[0141] In the above technical solution, when the UE performs cell switching (or cell reselection), the UE will only read the relevant SIB messages according to the first indication information, which allows the UE to read less of the SIB messages in some cases, instead of reading all the SIB messages about cell reselection, thereby saving UE power consumption and cell selection time; when the UE performs initial cell selection and is prohibited from staying in the current cell, the UE can read the relevant SIB messages instead of not reading all SIB messages and performing blind cell selection, thereby reducing the number of blind cell selections and saving UE power consumption and cell selection time.
[0142] It should be understood that when network devices broadcast these SIB messages, SIBs with the same transmission period can be mapped to the same or different system messages, and SIBs with different transmission periods cannot be mapped to the same system message. Therefore, when these SIB messages have different transmission periods, SIB2, 3, 4, and 5 may be mapped to different system messages. In this case, the above solution can save UE power consumption and cell selection time, that is, reading one or more SIB messages instead of reading all of them.
[0143] The above describes in detail the information indication method provided by the present application. The following introduces the communication device provided by the present application.
[0144] See also Figure 6 , Figure 6 It is a schematic block diagram of the communication device 1000 provided in this application.
[0145] In one possible design, a communication device 1000 includes a receiving unit 1100 and a processing unit 1200.
