DETAILED DESCRIPTION

The network equipment knows too little about the terminal and cannot perform reasonable scheduling.

In a first aspect, an embodiment of the present disclosure provides an information transmission method, which is executed by a terminal, and the method includes:

In the above embodiment, at least one of the first information and the second information is sent to the network device by the terminal, so that the network device can learn from the first information that the terminal is a terminal that obtains power from the environment, and/or learn from the second information the power obtaining capability and/or the electric energy storage capability of the terminal. In this way, the network device can reasonably schedule the terminal, thereby improving communication performance.

In combination with some embodiments of the first aspect, in some embodiments, sending at least one of the first information and the second information to the network device includes:

During a random access process, at least one of the first information and the second information is sent to the network device.

In the above embodiment, the terminal sends the first information and the second information to the network device during the random access process, so that the network device can reasonably schedule the terminal as early as possible, thereby improving the communication performance as early as possible.

In combination with some embodiments of the first aspect, in some embodiments, sending at least one of the first information and the second information to the network device during the random access process includes at least one of the following:

Sending a first random access message to the network device through a first resource; wherein the first resource is used to indicate at least one of the first information and the second information;

Sending a second random access message to the network device; wherein the second random access message carries at least one of the first information and the second information.

In the above embodiment, since the terminal can implicitly send at least one of the first information and the second information to the network device through the first resource during the random access process, the network device can reasonably schedule the terminal as early as possible and reduce signaling overhead.

In addition, since the terminal uses the first resource to indicate at least one of the first information and the second information during the random access process, the terminal that obtains power from the environment can be isolated from other types of terminals different from the terminal on the uplink resources used for the random access process, which is beneficial to improving the random access success rate of the terminal and reducing the random access delay of the terminal.

In addition, the terminal may also send a random access message of a random access process to the network device. Since the information carried by the random access message can clearly indicate at least one of the first information and the second information, the network device can directly determine that the terminal is a terminal that obtains power from the environment and/or the terminal's power acquisition capability and/or electrical energy storage capability, so that the terminal can be reasonably scheduled as early as possible.

Ambient-IoT is a type of Internet of Things. Compared with NB-IoT terminals, Ambient-IoT terminals are less complex, less expensive, and have lower maintenance costs. Their main features are that they do not have batteries, but are stimulated and powered by the electromagnetic signals they receive, or have batteries with a small amount of electrical storage function, but the batteries do not need to be charged manually, but can obtain a small amount of battery energy from external energy, such as by obtaining external electromagnetic waves, heat energy, kinetic energy, etc.

In some embodiments, for terminals that obtain energy from the environment, different terminals may have different capabilities for obtaining and storing electrical energy. For example, some terminals can obtain energy in a shorter time (here, obtaining energy can be understood as obtaining energy from the environment and charging the battery to a predetermined amount), and the battery storage capacity is lower; some terminals can obtain energy in a shorter time, and the battery storage capacity is higher; some terminals require a longer time to obtain energy, and the battery storage capacity is lower; some terminals require a longer time to obtain energy, and the battery storage capacity is higher.

In some embodiments, the terminal that obtains power from the environment accesses the network through a random access process. For example, the random access process may be a four-step random access process or a two-step random access process.

For the four-step random access process, the terminal sends a PRACH channel (also called Msg1, or message 1), and the base station will reply with a RAR (Random Access Response) after receiving it. Here, RAR can also be called Msg2 or message 2, which may include a TA (Timing Advance) indication, a TC-RNTI (Cell-Radio Network Temporary Identifier), and an uplink time-frequency resource indication for Msg3 (also called message 3). The UE sends Msg 3 according to the uplink time-frequency resource indication sent by the base station. Msg 3 may include a terminal identifier (ID) and possible non- Access layer NAS (Non-Access-Stratum, NAS) message, the base station successfully receives Msg 3 and replies with a contention resolution message.

For the two-step random access process, the terminal sends MsgA to the base station, and the base station replies with a contention resolution message MsgB after correctly receiving MsgA. MsgA here is equivalent to the above-mentioned Msg1+Msg3, and may include PRACH and PUSCH (Physical Uplink Shared Channel). Among them, the PUSCH configuration may have a corresponding relationship with the PRACH configuration.

The present disclosure embodiment provides a flow chart of an information transmission method. The present disclosure embodiment relates to an information transmission method, the method comprising:

During the random access process, the terminal sends the type and/or terminal capability of the terminal to the base station, wherein the terminal type identifies whether the terminal is a terminal type that obtains energy from the environment, and the terminal capability identifies the energy obtaining capability and/or electric energy storage capability of the terminal.

In some embodiments, a terminal is identified as a terminal that obtains power from the environment through a specific PRACH resource.

As an example, the specific PRACH resources include frequency domain resources and/or time domain resources and/or code domain resources of a specific PRACH (which can be understood as different preamble sequences). When the terminal initiates random access, if the specific PRACH resource is selected to initiate random access, it means that the terminal is a terminal that obtains power from the environment.

As an example, the specific PRACH resource includes multiple time domain symbols on the time domain resource for repeated transmission of the PRACH channel. The purpose of repeated transmission is to compensate for the problem of power limitation and ensure uplink coverage.

In some embodiments, a terminal is identified as a terminal type that obtains capabilities from the environment through a specific Msg A resource.

As an example, the specific Msg A resources include specific PRACH resources and/or specific PUSCH resources in the Msg A transmission resources. The specific PRACH resources include specific PRACH frequency domain resources and/or time domain resources and/or code domain resources. The specific PUSCH resources include specific PUSCH frequency domain resources and/or time domain resources.

As an example, the terminal type may be identified by a specific PUSCH resource, or may be identified by a specific PRACH resource and a specific PUSCH resource.

As an example, the specific resource of Msg A includes multiple time domain symbols on the time domain resources for repeated transmission of Msg A.

In some embodiments, the terminal type is identified by information carried in Msg3 or Msg A. For example, the terminal type flag information is directly carried in Msg 3 or Msg A to indicate that the terminal is a terminal type that obtains power from the environment.

As an example, the Msg3 or Msg A may also be repeatedly transmitted in the time domain to improve coverage.

In some embodiments, information about the terminal's power acquisition capability and/or power storage capability is carried in Msg3 or Msg A.

In some embodiments, the terminal energy acquisition capability and battery energy storage capability may be defined in the protocol.

For example, the battery energy storage capability may define different capability levels. An example of capability definition is capability 1: the battery energy storage is sufficient for a single reception or a single transmission (or other UE operations), capability 2: the battery energy storage is sufficient for a single reception and transmission (or other UE operations), and capability 3: the battery energy storage is sufficient for multiple communication processes within a duration T. For another example, the battery energy storage capability may be directly divided according to the absolute value of the battery energy storage.

For example, the terminal energy acquisition capability indicates how long the terminal can collect a set amount of energy. The set amount is related to the battery storage capacity. For example, when the battery storage capacity of the terminal is capacity 1 and the terminal communication recovery capacity is duration T1, it means The terminal can collect enough energy for a single reception or a single transmission (or other terminal operations) within the duration T1. When the battery storage capacity of the terminal is capacity 2 and the terminal communication recovery capacity is duration T2, it means that the terminal can collect enough energy for a single reception and transmission (or other terminal operations) within the duration T2. When the battery storage capacity of the terminal is capacity 3 and the terminal communication recovery capacity is duration T3, it means that the terminal can collect enough energy for multiple communication processes within duration T within duration T3.
