Description

[Technical field]

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, apparatus and communication device for transmitting a system message. [Background technology]

[0002] In the LTE 4G system, two technologies, MTC (Machine Type Communication) and NB-IoT (Narrow band Internet of things), are proposed to support Internet of Things services. These two technologies target scenarios with low data rates and high latency, such as meter reading and environmental monitoring. Currently, NB-IoT can only support rates up to a few hundred Kbps, and currently, MTC can only support rates up to a few Mbps.

[0003] With the development of Internet of Things services, such as video surveillance, smart home, wearable devices, and industrial sensing monitoring, these services usually require rates of tens to hundreds of trillions of bits, and at the same time have relatively high requirements for latency. Therefore, MTC and NB-IoT technologies in LTE have difficulty meeting these requirements. Based on this situation, 5G (5th generation mobile networks) new radio proposed to redesign new UE (User Equipment) to cover the requirements of such mid-range Internet of Things devices. In the current 3GPP standardization, such a new terminal type is called Reduced capability UE, or simply NR-lite.

[0004] Like LTE Internet of Things devices, based on 5G NR-lite, they usually need to meet requirements such as low cost, low complexity, a certain degree of coverage extension, and power saving. However, the current NR (New Radio) is designed for high-end terminals such as high rates and low latency, so the current NR cannot meet the above requirements of NR-lite.

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the drawings. Where the following description refers to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise stated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the embodiments of the present disclosure, as detailed in the appended claims.

[0028] The terms used in the embodiments of the present disclosure are merely for the purpose of describing particular embodiments and are not intended to limit the embodiments of the present disclosure. The singular forms "a" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should be understood that the term "and / or" as used herein refers to and includes any and all combinations of one or more of the associated listed items.

[0029] In the embodiments of the present disclosure, terms such as first, second, third, etc. may be used to describe various pieces of information, but it should be understood that these pieces of information should not be limited to these terms. These terms are merely used to distinguish between the same types of information. For example, the first piece of information can be referred to as the second piece of information, and similarly, the second piece of information can be referred to as the first piece of information, without departing from the scope of the embodiments of the present disclosure. Depending on the context, the words "when" and "if" as used herein can be interpreted as "when" or "in the case of" or "responsive to a determination."

[0030] Hereinafter, the embodiments of the present disclosure will be described in detail, examples of which are illustrated in the accompanying drawings, in which the same or similar reference numerals throughout indicate the same or similar elements. The embodiments described below with reference to the accompanying drawings are for the purpose of illustrating the present disclosure, and should not be understood as limitations on the present disclosure.

[0031] The current NR new radio is designed for high-end terminals such as high rate and low latency, so the current design cannot meet the requirements of NR-lite such as low rate and high latency. Therefore, it is necessary to modify the current NR system to meet the requirements of NR-lite. For example, to meet the requirements of low cost and low complexity, the RF (Radio Frequency) bandwidth of NR-IoT can be limited, for example, to 5 MHz or 10 MHz, or the size of the NR-lite buffer can be limited, and the size of the transmission block received each time can be limited. For power saving, possible optimization directions are to simplify the communication flow and reduce the number of times that NR-lite users detect the downlink control channel.

[0032] In response to the above problems, the present disclosure provides a method, apparatus and communication device for transmitting a system message.

[0033] 1 is a schematic flowchart of a system message transmission method provided by an embodiment of the present disclosure, which can be applied to Redcap User Equipment (Redcap UE).

[0034] As shown in FIG. 1, the system message transmission method may include the following steps 101-102.

[0035] In step 101, an instruction message is received.

[0036] Here, the indication message is used to indicate the monitoring behavior of the red cap UE.

[0037] In an embodiment of the present disclosure, the redcap UE may receive an indication message sent from a network side device to indicate a monitoring behavior of the redcap UE.

[0038] As an example, the instruction message may instruct the red cap UE to monitor system message A or not to monitor system message B.

[0039] Here, the redcap UE has advantages such as coverage extension and power saving compared to the non-redcap UE.

[0040] In step 102, the system messages to be monitored are determined based on the indication message.

[0041] In an embodiment of the present disclosure, after receiving an indication message sent from a network side device, the red cap UE can determine the system messages to be monitored based on the indication message.

[0042] As an example, assuming that an instruction message instructs the red cap UE to monitor system message A and not to monitor system message B, after receiving this instruction message, the red cap UE can decide to monitor system message A.

[0043] In the system message transmission method of the embodiment of the present disclosure, a red cap UE receives an indication message, the indication message is used to indicate a monitoring behavior of the red cap UE, and the red cap UE determines a system message to be monitored based on the indication message, which is advantageous in that the red cap UE determines a system message to be monitored based on the received indication message, thereby improving the monitoring efficiency of the red cap UE.

[0044] It should be noted that the above possible implementation forms may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0045] The embodiment of the present disclosure provides another system message transmission method, and Fig. 2 is a schematic flowchart of another system message transmission method provided by the embodiment of the present disclosure. This system message transmission method can be applied to a red cap UE. This system message transmission method may be performed alone, or may be performed in combination with any embodiment or possible implementation form of the embodiment of the present disclosure, or may be performed in combination with any technical solution of the related art.

[0046] As shown in FIG. 2, the system message transmission method can include the following steps 201 to 203.

[0047] In step 201, an indication message is received, and the indication message is used to indicate the monitoring behavior of a redcap UE.

[0048] In an embodiment of the present disclosure, the redcap UE may receive an indication message sent from a network side device to indicate a monitoring behavior of the redcap UE.

[0049] As one possible case of an embodiment of the present disclosure, the instruction message can instruct the redcap UE to monitor a first system message or not to monitor a second system message, where the first system message corresponds to the redcap UE and the second system message corresponds to a system message defined in the existing system.

[0050] As an example, the instruction message may instruct the Redcap UE to monitor Redcap-specific SIBs (system information blocks) or not to monitor existing RMSI messages (Remaining minimum system information).

[0051] As another possible case of the embodiment of the present disclosure, the indication message may further include a MIB (Master Information Block), where the MIB is used to indicate the monitoring behavior of the redcap UE.

[0052] Alternatively, free bits or other reserved bits in the MIB may be used to indicate the monitoring behavior of the red cap UE.

[0053] As another possible case of an embodiment of the present disclosure, the instruction message can further include a PDCCH (Physical Downlink Control Channel), where the PDCCH is used for the second system message, and the PDCCH is used to indicate the monitoring behavior of the red-cap UE.

[0054] Alternatively, the PDCCH included in the indication message may be for scheduling RMSI messages as defined in existing systems. Reserved bits in the PDCCH may be used to communicate subsequent system message monitoring.

[0055] As an example, a reserved bit in the PDCCH may be used to inform the red cap UE to monitor for the second system message.

[0056] As another possible case of an embodiment of the present disclosure, the instruction message can further include a PDSCH (Physical Downlink Shared Channel), where the PDSCH is used for the second system message, and the PDSCH is used to indicate the monitoring behavior of the redcap UE.

[0057] Alternatively, the PDSCH included in the indication message may be a scheduling RMSI message defined in existing systems. A reserved bit in the PDSCH may be used to signal subsequent system message monitoring.

[0058] As an example, a reserved bit in the PDSCH may be used to inform the red cap UE to monitor for the second system message.

[0059] In step 202, in response to the indication message being in a first state, monitor a first system message or do not monitor a second system message.

[0060] In an embodiment of the present disclosure, after receiving an indication message sent from a network side device, if the redcap UE determines that the indication message is in a first state, the redcap UE can monitor a first system message or not monitor a second system message.

[0061] As an example, assuming that the indication message is 0, after the red cap UE receives the indication message, it monitors the first system message or does not monitor the second system message.

[0062] In step 203, in response to the indication message being in a second state, a second system message is monitored.

[0063] In an embodiment of the present disclosure, after the redcap UE receives an indication message sent from the network side device, when the redcap UE determines that the indication message is in a second state, the redcap UE can monitor a second system message.

[0064] As an example, assuming the indication message is 1, after the red cap UE receives the indication message, it monitors the second system message.

[0065] In the embodiment of the present disclosure, the above steps 202 and 203 are not sequentially executed, but rather it is determined whether to execute step 202 or step 203 based on the state of the instruction message.

[0066] In the system message transmission method of the embodiment of the present disclosure, after the red cap UE receives an indication message, in response to the indication message being in a first state, the red cap UE monitors the first system message or does not monitor the second system message, and in response to the indication message being in a second state, the red cap UE determines to monitor the first system message or the second system message based on the state of the received indication message, which is advantageous to improving the monitoring efficiency of the red cap UE.

[0067] It should be noted that the above possible implementation forms may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0068] The embodiment of the present disclosure provides another system message transmission method, and Fig. 3 is a schematic flowchart of another system message transmission method provided by the embodiment of the present disclosure. This system message transmission method can be applied to a red cap UE. This system message transmission method may be performed alone, or may be performed in combination with any embodiment or possible implementation form of the embodiment of the present disclosure, or may be performed in combination with any technical solution of the related art.

[0069] As shown in FIG. 3, the system message transmission method may include the following steps 301 to 303.

[0070] In step 301, an indication message is received, and the indication message is used to indicate the monitoring behavior of a redcap UE.

[0071] In step 302, in response to the indication message being in a first state, a first system message is monitored.

[0072] In the embodiment of the present disclosure, the implementation process of step 301 and step 302 can refer to the implementation process of step 201 and step 202 in the above embodiment, and the description is omitted here.

[0073] In step 303, transmission parameters of a first system message are determined.

[0074] In an embodiment of the present disclosure, after receiving an indication message sent from a network side device, when the red cap UE determines that the indication message is in a first state, it monitors a first system message and further determines transmission parameters of the first system message.

[0075] Optionally, the transmission parameters of the first system message may include at least one of parameters of a BWP (Bandwidth Part) in which the first system message resides, set parameters of a CORESET (Control Resource Set) for scheduling the first system message, and set parameters of a PDSCH for scheduling the first system message.

[0076] In one possible case of an embodiment of the present disclosure, at least some of the following transmission parameters of the first system message are the same as the transmission parameters corresponding to the second system message, including bandwidth, SCS (Sub-Carrier Spacing), and MCS (Modulation and Coding Scheme):

[0077] Here, rate configuration in LTE is achieved by MCS index values. The MCS form a rate table, with the factors influencing the communication rate of interest as the columns of the table and the MCS index as the rows. Thus, each MCS index actually corresponds to a physical transmission rate for one set of parameters.

[0078] As one possible implementation form of an embodiment of the present disclosure, when determining the transmission parameters of the first system message, the transmission parameters of the first system message can be determined based on a predefined reel, for example, predefining that the bandwidth of the first system message and the bandwidth of the second system message are the same, predefining that the first system message and the second system message have the same SCS, and predefining that the first system message and the second system message have the same MCS.

[0079] For example, it is predefined that the BWP transmitting the Redcap-SIB and the Initial BWP (initial bandwidth) of the non-Redcap UE have the same bandwidth and the same SCS, and the RMSI of the Redcap-SIB and the non-Redcap UE have the same MCS.

[0080] As another possible implementation form of the embodiment of the present disclosure, when determining the transmission parameters of the first system message, the transmission parameters may be further determined based on the PDCCH.

[0081] As another possible implementation form of the embodiment of the present disclosure, when determining the transmission parameters of the first system message, the transmission parameters can be further determined based on the PDSCH.

[0082] As another possible implementation form of the embodiment of the present disclosure, when determining the transmission parameters of the first system message, the transmission parameters can be further determined based on the PDCCH and the PDSCH.

[0083] Optionally, the PDCCH and / or PDSCH include specific settings of transmission parameters, so that the transmission parameters of the first system message can be determined based on the PDCCH and / or PDSCH. In the embodiment of the present disclosure, the PDCCH may be a PDCCH shared by the redcap UE and the non-redcap UE, or a PDCCH dedicated to the redcap UE.

[0084] For example, the PDCCH may include a PDCCH that schedules RMSI for non-redcap UEs or a PDCCH intended for redcap UEs.

[0085] In the system message transmission method of the embodiment of the present disclosure, after the red cap UE receives an indication message, in response to the indication message being in a first state, the red cap UE monitors the first system message and determines transmission parameters of the first system message, so that the red cap UE determines to monitor the first system message and determines transmission parameters of the first system message according to the state of the received indication message, which is advantageous to improving the monitoring efficiency of the red cap UE.

[0086] It should be noted that the above possible implementation forms may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0087] The embodiment of the present disclosure provides another system message transmission method, and FIG. 4 is a schematic flowchart of another system message transmission method provided by the embodiment of the present disclosure. This system message transmission method can be applied to a network side device. This system message transmission method may be performed alone, or may be performed in combination with any embodiment or possible implementation form of the embodiment of the present disclosure, or may be performed in combination with any technical solution of the related art.

[0088] As shown in FIG. 4, the system message transmission method may include the following step 401.

[0089] In step 401, send an indication message, which is used to indicate a monitoring behavior of the redcap UE, so that the redcap UE determines the system messages to be monitored based on the indication message.

[0090] Here, the network side device is exemplified by a base station. The base station can include multiple cells that serve terminal devices. According to a specific application, each cell can also include multiple TRPs (Transmitting receiving points), or may be a device that communicates with wireless terminal devices through one or more sectors over the air interface in an access network, or other names. For example, the base station according to the embodiment of the present disclosure may be a BTS (Base Transceiver Station) in GSM (Global System for Mobile communications) or CDMA (Code Division Multiple Access), a base station (Node B) in WCDMA (Wide-band Code Division Multiple Access), an evolutional Node B (abbreviated as eNB or e-NodeB) in an LTE (long term evolution) system, a 5G base station (abbreviated as gNB) in a 5G network architecture (next generation system), a HeNB (Home evolved Node B), a relay node, a home base station (femto), a pico base station (pico), or the like, and is not limited to the embodiment of the present disclosure.

[0091] In an embodiment of the present disclosure, the network side device sends an indication message to the redcap UE, and after the redcap UE receives the indication message, it determines the system messages to be monitored based on the monitoring behavior instructed by the indication message.

[0092] In an embodiment of the present disclosure, the instruction message is used to instruct the redcap UE to monitor a first system message or not to monitor a second system message, where the first system message corresponds to the redcap UE and the second system message corresponds to a system message defined in the existing system.

[0093] Alternatively, the first system message may be a Redcap-specific SIB message, and the second system message may be an existing RMSI message.

[0094] As another possible case of the embodiment of the present disclosure, the indication message may further include a MIB, where the MIB is used to indicate the monitoring behavior of the redcap UE.

[0095] Alternatively, free bits or other reserved bits in the MIB may be used to indicate the monitoring behavior of the red cap UE.

[0096] As another possible case of an embodiment of the present disclosure, the instruction message can further include a PDCCH, where the PDCCH is used for the second system message, and the PDCCH is used to indicate the monitoring behavior of the redcap UE.

[0097] Alternatively, the PDCCH included in the indication message may be for scheduling RMSI messages as defined in existing systems. Reserved bits in the PDCCH may be used to communicate subsequent system message monitoring.

[0098] As an example, a reserved bit in the PDCCH may be used to inform the red cap UE to monitor for the second system message.

[0099] As another possible case of an embodiment of the present disclosure, the instruction message can further include a PDSCH, where the PDSCH is used for the second system message, and the PDSCH is used to indicate the monitoring behavior of the red-cap UE.

[0100] Alternatively, the PDSCH included in the indication message may be a scheduling RMSI message defined in existing systems. A reserved bit in the PDSCH may be used to signal subsequent system message monitoring.

[0101] As an example, a reserved bit in the PDSCH may be used to inform the red cap UE to monitor for the second system message.

[0102] In one possible case of an embodiment of the present disclosure, the indication message sent by the network side device to the redcap UE is in a first state, and after the redcap UE receives the indication message, when it determines that the indication message is in the first state, it monitors a first system message or does not monitor a second system message.

[0103] As an example, assuming that the indication message is 0, after the red cap UE receives the indication message, it monitors the first system message or does not monitor the second system message.

[0104] In one possible case of an embodiment of the present disclosure, the indication message sent by the network side device to the redcap UE is in a second state, and after the redcap UE receives the indication message, when it determines that the indication message is in the second state, it monitors a second system message.

[0105] As an example, assuming the indication message is 1, after the red cap UE receives the indication message, it monitors the second system message.

[0106] In one possible case of an embodiment of the present disclosure, the network side device sends an indication message to the red cap UE, and after receiving the indication message sent from the network side device, when the red cap UE determines that the indication message is in a first state, it monitors a first system message and further determines transmission parameters of the first system message.

[0107] Optionally, the transmission parameters of the first system message may include at least one of parameters of a BWP in which the first system message exists, set parameters of a CORESET for scheduling the first system message, and set parameters of a PDSCH for scheduling the first system message.

[0108] In one possible case of the embodiment of the present disclosure, at least some of the following transmission parameters of the first system message are the same as the transmission parameters corresponding to the second system message, the transmission parameters including: bandwidth, SCS and MCS.

[0109] Here, rate configuration in LTE is achieved by MCS index values. The MCS form a rate table, with the factors influencing the communication rate of interest as the columns of the table and the MCS index as the rows. Thus, each MCS index actually corresponds to a physical transmission rate for one set of parameters.

[0110] As one possible implementation form of an embodiment of the present disclosure, when determining the transmission parameters of the first system message, the transmission parameters of the first system message can be determined based on a predefined reel, for example, predefining that the bandwidth of the first system message and the bandwidth of the second system message are the same, predefining that the first system message and the second system message have the same SCS, and predefining that the first system message and the second system message have the same MCS.

[0111] For example, it is predefined that the BWP transmitting the Redcap-SIB and the Initial BWP (initial bandwidth) of the non-Redcap UE have the same bandwidth and the same SCS, and the RMSI of the Redcap-SIB and the non-Redcap UE have the same MCS.

[0112] As another possible implementation form of the embodiment of the present disclosure, when determining the transmission parameters of the first system message, the transmission parameters can be further determined based on the PDCCH or the PDSCH.

[0113] Alternatively, since the PDCCH and / or PDSCH includes specific settings of the transmission parameters, the transmission parameters of the first system message can be determined based on the PDCCH and / or PDSCH.

[0114] In the embodiment of the present disclosure, the PDCCH may be a PDCCH shared by redcap UEs and non-redcap UEs, or may be a PDCCH dedicated to redcap UEs.

[0115] For example, the PDCCH may include a PDCCH that schedules RMSI for non-redcap UEs or a PDCCH intended for redcap UEs.
