The disclosure relates to a field of wireless communication technology, in particular to a method for reporting information, an apparatus for reporting information and a storage medium.
In a wireless communication system, Machine Type Communication (MTC) technology and Narrow Band Internet of Things (NB-IoT) technology are proposed for low-rate and high-latency scenarios such as those typically used in Internet of Things (IoT) services. Due to the development and wide-spread adoption of the IoT services, the MTC technology and NB-IoT technology can no longer satisfy the rate and latency requirements of current IoT services. Therefore, a new kind of terminal, i.e., Reduced capability (Redcap) terminal, also referred to as NR-lite, is designed to provide the IoT service requirements.
According to a first aspect of the embodiments of the disclosure, a method for sending information, performed by a terminal, is provided. The method includes:
According to a second aspect of embodiments of the disclosure, a method for receiving information, performed by a network device, is provided. The method includes:
According to a third aspect of embodiments of the disclosure, a device for reporting information is provided. The device includes:
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the disclosure and together with the description serve to explain the principles of the disclosure.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the disclosure as recited in the appended claims.
It is understandable that the communication system between the network device and the terminals illustrated in
It is further understandable that the wireless communication system according to the embodiments of the disclosure is a network that provides the wireless communication function. The wireless communication system may employ different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier FDMA (SC-FDMA), and carrier sense multiple access/collision avoidance. Depending on factors such as capacity, rate, and delay of different networks, the networks can be classified as a second Generation (2G) network, a 3G network, a 4G network, or a future evolved network, such as a 5G network, which can also be called a new radio (NR) network. For easy of description, in this disclosure, sometimes the wireless communication network is simply referred to as a network.
The “network device” involved in the disclosure may also be referred to as a radio access network device. The radio access network device may be: a base station, an evolved base station (evolved node B, i.e., eNB), a femtocell, an access point (AP) in a wireless fidelity (WIFI) system, a radio relay node, a radio backhaul node, a transmission point (TP) or a transmission and reception point (TRP), a gNB in an NR system, or components or a part of the devices that constitute the base station. The network device may also be a vehicle-mounted device in a vehicle to everything (V2X) communication system. It should be understandable that the specific technology and the specific device form used by the network device are not limited in the embodiments of the disclosure.
The “terminal” involved in the disclosure may also be referred to as a terminal device, a use equipment (UE), a mobile station (MS), or a mobile terminal (MT), which is a device that provides voice and/or data connectivity to a user. For example, the terminal can be a handheld device or a vehicle-mounted device with a wireless connectivity function. For example, the existing terminals include a mobile phone, a pocket personal computer (PPC), a handheld computer, a personal digital assistant (PDA), a laptop, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, the terminal device may also be a vehicle-mounted device in the V2X communication system. It is understandable that the specific technology and the specific device form used by the terminal are not limited in the embodiments of this disclosure.
The Machine Type Communication (MTC) technology and the Narrow Band Internet of Thing (NB-IoT) technology are proposed for a Reduced capability user equipment (Redcap UE) in communication systems, such as a Long Term Evolution (LTE) 4G system, to support IoT services. These two kind of technologies mainly focus on low-rate and high-latency scenarios, such as meter reading, environmental monitoring, and other scenarios. The maximum transmission rate currently supported by the NB-IoT technology is several hundred kbps (kilo bits per second), while the maximum transmission rate currently supported by the MTC technology is several Mbps (million bits per second). However, with the continuous development of IoT services, such as population of services such as video monitoring, smart home, wearable device and industrial sensing monitoring, these services usually require a transmission rate ranging from tens of Mbps to 100 Mbps, and the above services also have relatively high requirements for latency, and thus the MTC technology and the NB-IoT technology in the LTE can hardly satisfy the requirements of the above services. Based on this case, designing a new UE in the 5G NR is proposed to cover the requirements of such mid-end IoT devices. In the current 3rd Generation Partnership Project (3GPP) standardization, this new type of terminal is called Reduced Capability (Redcap) terminal (or called Redcap UE) or simply referred to as NR-lite. There may be many different types of Redcap UEs in the communication system, such as high-end Redcap terminal and low-end Redcap terminal, and different terminal types may have different terminal capabilities or coverage capabilities. For example, the high-end terminal has 2 Rx antennas and the low-end terminal has only 1 Rx antenna, and thus these two terminals have different coverage capabilities.
Since the Redcap terminal has a small number of antennas and a relatively low coverage capability, the Redcap terminal needs to report its terminal capability or terminal type to a network in advance. In the related art, the terminal may report the terminal capability information or the terminal type through a random access message. However, the network needs to divide resources into different Physical Random Access Channels (PRACHs) and bandwidth parts (BWPs) for the terminal, resulting in resource fragmentations. Moreover, the terminal still needs to report information based on the access message Msg.1 when a configured initial BWP is small or the coverage is good, resulting in a waste of resources.
Since the terminal capability(ties) of the Redcap terminal is(are) different from the terminal capability(ties) of a normal terminal, the Redcap terminal needs to report to the network at least one of: the terminal capability, the terminal type or the channel state. In the related art, the terminal can report the terminal capability in two ways. The first way for reporting the terminal capability is reporting based on a transmission of the Msg. 1 in a random access process. That is, the network device assigns specific Msg. 1 transmission resources for the accesses of different types of Redcap terminals. For example, different initial bandwidth parts (BWPs), different Physical Random Access Channel (PRACH) transmission times, different transmission frequencies, or different random access preambles are configured for different types of Redcap terminals. The Redcap terminal selects a specific resource for access based on the capability, the type or the channel state. The network device determines the type, the capability or the channel state of the terminal based on the received Msg. 1. The second way for reporting the terminal capability is reporting based on a transmission of Msg. 3 in a random access process. The Redcap terminal carries its capability information, terminal type or the channel state information in a data packet of the Msg. 3 and sends it to the network device. The network device determines the type, the capability or the channel state of the Redcap terminal based on the received Msg. 3.
However, in the related art, one of the above-mentioned ways for reporting the terminal capability is allowed. Moreover, reporting the terminal capability based on the Msg. 1, needs to rely on the division of the PRACH resources by the network, resulting in resource fragmentations. Moreover, reporting the terminal capability based on the Msg. 1 is generally necessary only in the case where the configured initial BWP is larger or the terminal (or called UE) has poor coverage, resulting in the waste of resources.
On the basis, the disclosure provides a method for reporting information. According to the method, the network device and the terminal support reporting the terminal information based on the Msg.1 and the Msg. 3, the network can perform a configuration based on the state of the network or the terminal can make a selection based on the terminal side information according to the preconfigured or predefined rule, which not only inform the network of the terminal capability in a timely manner, but also avoids the waste of resources.
At step S11, a first random access message is determined from at least two types of random access messages supported by the terminal.
In embodiments of the disclosure, the terminal determines to support a plurality of random access messages through which the terminal capability information is reported, and the first random access message for reporting the terminal information is determined from the plurality of random access messages. It is noteworthy that the first access message may be one random access message or two or more random access messages.
At step S12, terminal information is reported based on the first random access message.
In embodiments of the disclosure, the terminal reports the terminal information based on the determined first random access message. The terminal information may include terminal information and/or channel state information of the terminal. The channel state information of the terminal may be a coverage situation of the terminal, such as a Reference Signal Receiving Power (RSRP) or a signal-to-noise interference ratio. The terminal can report the RSRP or the signal-to-noise interference ratio that represents the coverage situation of the terminal. The terminal information may be the terminal type and/or the terminal capability.
In some embodiments of the disclosure, the terminal type can be a high-end Redcap type that has a relatively high capability (high-end Redcap UE). For example, the high-end Redcap UE supports a bandwidth of 20 MHz and supports 2 antennas. The terminal type can be a low-end Redcap type which has a relatively low capability (low-end Redcap UE). For example, the low-end Redcap terminal supports a bandwidth of 20 MHz and supports 1 antenna. The terminal type can be other terminal types, which will not be exemplified here.
In some embodiments of the disclosure, the terminal capability may include any of: the number of antennas supported by the terminal, the transmitting and receiving bandwidth supported by the terminal, a duplex mode, or a modulation-demodulation mode supported by the terminal. For example, the terminal capability may be supporting 2 antennas or supporting 1 antenna. In some embodiments of the disclosure, the coverage situation of the terminal may be an RSRP measurement value. The coverage situation of the terminal may also be a situation where the RSRP measurement value satisfies a first threshold value. For example, if the RSRP measurement value of the terminal is greater than or equal to the first threshold value, it is determined that the coverage situation of the terminal is relatively good, and the coverage situation of the terminal that reports the capability information to the network device is relatively good. If the RSRP measurement value of the terminal is less than or equal to the first threshold value, it is determined that the coverage situation of the terminal is relatively poor, and the coverage situation of the terminal that reports the terminal capability information to the network device is relatively poor.
In the embodiments of the disclosure, the plurality of random access messages supported by the terminal for reporting the capability information at least include a first type of random access message and a second type of random access message. In some possible implementations, the first type of random access message can be the Msg. 1 in a random access process of the terminal. In other possible implementations, the second type of random access message can be the Msg. 3 in a random access process of the terminal. The above is only an example and is not used as a specific limitation herein.
In some embodiments of the disclosure, in response to the first type of random access message being the Msg. 1, a transmission resource of the Msg. 1 is determined. The transmission resource of the Msg. 1 is determined by the network device, for example, the network device assigns the resource for the Msg. 1 based on the terminal information. The transmission resource includes at least one of:
For example, as shown in Table 1, the first type of terminal corresponds to a first PRACH resource set and the second type of terminal corresponds to a second PRACH resource set.
It is understandable that each element in Table 1 exists independently of each other, and these elements are exemplarily listed in the same table, but it does not mean that all of the elements in the table must exist at the same time as shown in Table 1. The value of each of these elements is independent of any other element value in Table 1. Therefore, it is understandable by those skilled in the art that the value of each of the elements in Table 1 is an independent embodiment.
For example, as shown in Table 2, “first type of terminal and channel state value of the terminal is greater than the first threshold value” corresponds to a third PRACH resource set, “first type of terminal and channel state value of the terminal is less than the first threshold value” corresponds to a fourth PRACH resource set, “second type of terminal and channel state value of the terminal is less than the first threshold value” corresponds to a fifth PRACH resource set, and “second type of terminal and channel state value of the terminal is greater than the first threshold value” corresponds to a sixth PRACH resource set.
It is understandable that each of the elements in Table 2 exists independently of each other, and these elements are exemplarily listed in the same table, but it does not mean that all of the elements in the table must exist at the same time as shown in Table 2. The value of each of these elements is independent of any other element value in Table 2. Therefore, it is understandable by those skilled in the art that the value of each of the elements in Table 2 is an independent embodiment.

At step S41, first information is determined, in response to that the first random access message being the first type of random access message.
In the embodiment of the disclosure, the first information includes at least one of a terminal capability, a terminal type or a channel state value of the terminal.

In the embodiment of the disclosure, the correspondence between the terminal information and the PRACH resource set of Msg. 1 is determined based on the communication protocol, the terminal determines the terminal information and then determines the transmission resource corresponding to the terminal information.
In some embodiments, the method further includes a step S43.
At step S43, the terminal information is reported based on the transmission resource.
In an implementation of the disclosure, the first information includes the terminal type. As shown in Table 1, the terminal information is reported based on a first PRACH resource set, in response to that the terminal type being the first type. In an implementation, the first information includes the terminal type and the channel state value of the terminal. As shown in Table 2, the terminal information is reported based on a first PRACH resource set, in response to that the terminal type being the first type and the channel state value of the terminal being greater than the first threshold value.

In the embodiment of the disclosure, the pre-configuration information is carried by a system message. The terminal determines, based on the received system message, the first random access message for reporting the terminal information.
For example, as shown in Table 3, if the channel state value of the terminal included in the terminal information is less than the first threshold value, the terminal reports the terminal information based on the first type of random access message (e.g., Msg. 1) and determines to report the terminal information based on the seventh PRACH resource set. If the channel state value of the terminal included in the terminal information is greater than the first threshold value, the terminal reports the terminal information based on the second type of random access message (e.g., Msg. 3).
It is understandable that each of the elements in Table 3 exists independently of each other, and these elements are exemplarily listed in the same table, but it does not mean that all of the elements in the table must exist at the same time as shown in Table 3. The value of each of these elements is independent of any other element value in Table 3. Therefore, it is understandable by those skilled in the art that the value of each of the elements in Table 3 is an independent embodiment.
At step S71, a first indication message is obtained.
In the embodiment of the disclosure, the first indication message is configured to indicate a random access message through which the terminal reports the terminal information. The first indication message may be a system message. The terminal receives the first indication message sent by the network device.
At step S72, the first random access message is determined based on the first indication message.
In the embodiment of the disclosure, the terminal determines, based on a way for reporting the terminal information indicated by the first indication message, the first random access message for reporting the terminal information.
In the embodiment of the disclosure, the terminal may obtain the first indication message based on the following ways.
At step S81, the first indication message is obtained based on a preconfigured information field.
In the embodiment of the disclosure, the network device may indicate the first random access message to be used by the terminal for reporting the terminal information via an explicit signaling, such as via a configured information field. In response to a value of the information field being 1, the first type of random access message (e.g., the Msg. 1) is used to report the terminal information, and in response to the value of the information field being 0, the second type of random access message (e.g., the Msg. 3) is used to report the terminal information.
At step S91, the first indication message is obtained based on a PRACH.
In the embodiment of the disclosure, the network device may indicate, via an implicit signaling, the first random access message to be used by the terminal for reporting the terminal information. The division of PRACH resource is taken as an example. In response to the terminal assigning a resource used for the early indication for the Redcap terminal in the PRACH resource, it is determined that the terminal reports the terminal information based on the corresponding transmission resource represented by the first type of random access message (e.g., the Msg. 1). In response to the terminal not assigning the resource used for the early indication for the Redcap terminal in the PRACH resource, it is determined that the terminal reports the terminal information based on the second type of random access message (e.g., the Msg. 3).
In the embodiment of the disclosure, the first access resource is determined based on the terminal information, for reporting the terminal information, in response to the terminal determining that the plurality of random access messages are supported for reporting the terminal information. For example, in an implementation, the terminal information includes the terminal capability, the terminal capability includes the number of receiving antennas. It is determined that the first type of random access message is determined from the plurality of random access messages, and it is determined that the terminal information is reported based on the first type of random access message (i.e., the Msg. 1). The corresponding transmission resource is determined based on the number of receiving antennas, in which the transmission resource has been described in the above embodiments. In an implementation, the terminal determines that the supported modulation mode is 256 Quadrature Amplitude Modulation (QAM), determines the second type of random access message from the plurality of random access messages, and determines to report the terminal information based on the second type of random access message (i.e., the Msg. 3).

It is noteworthy that the first access message may be one random access message or two or more random access messages.
At step S102, the terminal information is received based on the first random access message.
In the embodiment of the disclosure, the network device receives the terminal information based on the determined first random access message. The terminal information may include terminal information and/or channel state information of the terminal. The channel state information of the terminal may be a coverage situation of the terminal, such as a RSRP or a signal-to-noise interference ratio, such that the terminal reports the RSRP or the signal-to-noise interference ratio that represents the coverage situation of the terminal. The terminal information may be a terminal type and/or a terminal capability.
In some embodiments of the disclosure, the terminal type can be a high-end Redcap type having a relatively high capability (high-end Redcap UE). For example, the high-end Redcap UE supports a bandwidth of 20 MHz and supports 2 antennas. The terminal type can be a low-end Redcap type having a relatively low capability (low-end Redcap UE). For example, the low-end Redcap UE supports a bandwidth of 20 MHz and supports 1 antenna. The terminal type can be other terminal types, which will not be exemplified here.

In some embodiments of the disclosure, the coverage situation of the terminal may be an RSRP measurement value. The coverage situation of the terminal may be a situation where the RSRP measurement value satisfies a first threshold value. For example, if the RSRP measurement value of the terminal is greater than or equal to the first threshold value, it is determined that the coverage situation of the terminal is relatively good, and the coverage situation of the terminal that reports the terminal capability information to the network device is relatively good. If the RSRP measurement value of the terminal is less than or equal to the first threshold value, it is determined that the coverage situation of the terminal is relatively poor, and the coverage situation of the terminal that reports the capability information to the network device is relatively poor.
In the embodiments of the disclosure, the plurality of random messages supported by the terminal for reporting the capability information at least include a first type of random access message and a second type of random access message. For example, the first type of random access message can be the Msg.1 in a random access process of the terminal, and the second type of random access message can be the Msg.3 in a random access process of the terminal. The above is only an example and is not used as a specific limitation herein.

The transmission resource of Msg. 1 is determined by the network device, for example, the network device assigns the resource for the Msg. 1 based on the terminal information. The transmission resource includes at least one of:

In the embodiment of the disclosure, the first information includes at least one of the terminal capability, the terminal type and the channel state value of the terminal, and the first type of random access message includes a plurality of transmission resources for representing the terminal information. In the embodiment of the disclosure, it is determined that the first random access message configured by the network side for the terminal for reporting the terminal information is the first type of random access message, and further the terminal information is determined.
At step S132, a transmission resource corresponding to the first information is determined based on a correspondence between the first information and the transmission resource.
In the embodiment of the disclosure, the correspondence between the terminal information and the PRACH resource set of the Msg. 1 is determined based on the communication protocol, the terminal information of the terminal is determined, and the transmission resource corresponding to the terminal information is determined.
In some embodiments, the method further includes a step S133.
At step S133, the terminal information is received based on the transmission resource.
In an implementation of the disclosure, the first information includes the terminal type. As shown in Table 1, the terminal information is reported based on a first PRACH resource set, in response to the terminal type being a first type of terminal. In an implementation, the first information includes the terminal type and the channel state value of the terminal. As shown in Table 2, the terminal information is reported based on the third PRACH resource set, in response to the terminal type being the first type of terminal and the channel state value of the terminal being greater than the first threshold value.
At step S141, in response to the first random access message being the second type of random access message, the terminal information is received based on the second type of random access message.
In the embodiment of the disclosure, it is determined that the first random access message configured by the network side for the terminal for receiving the terminal information is the second type of random access message, and the terminal information is received based on the second type of random access message.
At step S151, it is determined, depending on a predefined rule, pre-configuration information or a communication protocol, that the terminal information is received based on the first type of random access message or the terminal information is received based on the second type of random access message.
In some embodiments, the at least two types of random access messages supported by the terminal include: a first type of random access message and a second type of random access message. That is, the first random access message may be the first type of random access message or the second type of random access message. In the embodiment of the disclosure, it is determined that the at least two types of random access messages configured by the network device for the terminal, including the first type of random access message and the second type of random access message. The terminal reports its own terminal information, and the network device determines that the terminal information is received based on the first type of random access message or the terminal information is received based on the second type of random access message.
In the embodiment of the disclosure, the pre-configuration information is carried by a system message. The terminal determines, based on the received system message, the first random access message for reporting the terminal information.
For example, as shown in Table 3, the channel state value of the terminal contained in the terminal information is less than the first threshold value, and then it is determined that the terminal information is received based on the first type of random access message (e.g., the Msg. 1) and it is further determined to receive the terminal information based on the seventh PRACH resource set. The channel state value of the terminal contained in the terminal information is greater than the first threshold value, and then it is determined that the terminal information is received based on the second type of random access message (e.g., the Msg. 3).
At step S161, a first indication message is sent.
In the embodiment of the disclosure, the first indication message is used to indicate a random access message through which the terminal reports the terminal information. The first indication message may be a system message. The terminal receives the first indication message sent by the network device.
At step S162, a first random access message is determined based on the first indication message.
In the embodiment of the disclosure, the terminal determines, based on a way for reporting the terminal information indicated by the first indication message, the first random access message for reporting the terminal information.
In the embodiment of the disclosure, the network device may send the first indication message based on the following ways.
At step S171, the first indication message is sent based on a preconfigured information field.
In the embodiment of the disclosure, the network device may indicate, via an explicit signaling, the first random access message to be used by the terminal for reporting the terminal information, for example via configuring an information field. The first type of random access message (e.g., the Msg. 1) is used to receive the terminal information in response to a value of the information field being 1, and the second type of random access message (e.g., the Msg. 3) is used to receive the terminal information in response to the value of the information field being 0.
At step S181, the first indication message is sent based on a PRACH.
In the embodiment of the disclosure, the network device may indicate, via an implicit signaling, the first random access message to be used by the terminal for receiving the terminal information. The division of the PRACH resource is taken as an example. It is determined that the terminal receives the terminal information based on the corresponding transmission resource represented by the first type of random access message (e.g., the Msg. 1) in response to the terminal assigning a resource used for the early indication for the Redcap terminal in the PRACH resource. It is determined that the terminal receives the terminal information based on the second type of random access message (e.g., the Msg. 3) in response to the terminal not assigning the resource used for the early indication for the Redcap terminal in the PRACH resource.
In the embodiment of the disclosure, in response to the terminal determining that the plurality of random access messages are supported for reporting the terminal information, the first access resource is determined based on the terminal information, for reporting the terminal information. For example, in an implementation, the terminal information includes the terminal capability. The terminal capability includes the number of receiving antennas. It is determined that the first type of random access message is determined from the plurality of random access messages, and it is determined that the terminal information is reported based on the first type of random access message (i.e., the Msg. 1). The corresponding transmission resource is determined based on the number of receiving antennas, in which the transmission resource has been described in the above embodiments. In an implementation, the terminal determines that the supported modulation mode is 256 QAM, determines that the second type of random access message is determined from the plurality of random access messages, and determines to report the terminal information based on the second type of random access message (i.e., the Msg. 3).

In some examples, a device for receiving information is provided. The device includes: a processor and a memory for storing instructions executable by the processor, in which the processor is configured to perform the methods for receiving information as described above.
In some examples, a non-transitory computer-readable storage medium having instructions stored thereon is provided. When the instructions are executed by a processor of a mobile terminal, the mobile terminal is caused to perform the methods as described above.
The technical solutions according to embodiments of the disclosure may include the following beneficial effects. By determining the random access messages supported by the network device and the terminal to send the terminal capabilities, the network can perform a configuration according to the state of the network or the terminal can make a selection according to the preconfigured or predefined rule and based on the terminal side information, which not only inform the network of the terminal capability in a timely manner, but also avoids the waste of resources.
It is further understandable that the term “multiple” in the disclosure refers to two or more, which is the similar for other quantifiers. The term “and/or” describes a relation of associated objects, which indicates three relations, for example, “A and/or B” indicates that A exists alone, A and B both exist, and B exists alone. The character “/” generally indicates that the associated objects prior to and after the character “/” is an “or” relation. The terms “a”, “said” and “the” in the singular form are also intended to include the plural form, unless the context clearly indicates otherwise.
It is further understood that the terms “first”, “second”, etc. are used to describe various types of information, but that such information should not be limited to these terms. These terms are used only to distinguish information of the same type from each another and do not indicate a particular order or degree of importance. In fact, the expressions “first” and “second” can be used interchangeably. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.
It is further understandable that although the operations are depicted in the accompanying drawings in a particular order in the embodiments of the disclosure, this should not be construed as requiring that the operations be performed in the particular sequence shown or in a serial sequence, or that all of the operations shown be performed to obtain the desired results. Multitasking and parallel processing may be advantageous in particular environments.
