Description

Information transmission method and device, and terminal

Technical Field

The embodiment of the application relates to the technical field of mobile communication, in particular to an information transmission method, an information transmission device and a terminal.

Background

To meet the requirements of people on speed, delay, high-speed mobility, energy efficiency, and diversity and complexity of services in future life, the international standards organization of the third Generation Partnership Project (3 GPP) began to develop the fifth Generation (5G, 5G)^thGeneration) mobile communication technology.

An air interface part of the 5G mobile communication technology is called a New air interface (NR), and when NR is deployed in an early stage, complete NR coverage is difficult to achieve, so typical network coverage is a combination of Long Term Evolution (LTE) coverage and NR coverage. Furthermore, to protect the early LTE investment of mobile operators, a tightly coupled (light interworking) mode of operation between LTE and NR is proposed. Of course, NR cells may also be deployed independently.

In NR, the power level of User Equipment (UE) is generally 23dBm by default, and a high power level of 26dBm is proposed in order to enable good uplink coverage at the edge of a cell or in an environment with poor channel conditions. However, the UE power level variation may affect the scheduling and data demodulation performance of the UE on the network side.

The technical solution of the embodiment of the present invention is mainly applied to a 5G mobile communication system, and certainly, the technical solution of the embodiment of the present invention is not limited to the 5G mobile communication system, and can also be applied to other types of mobile communication systems. The following describes the main application scenarios in the 5G mobile communication system:

1) eMB scene: the eMBB targets users to obtain multimedia content, services and data, and its traffic demand is growing very rapidly. Because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the service capability and the requirement is relatively large, the service must be analyzed in combination with the specific deployment scenario.

2) URLLC scene: typical applications of URLLC include: industrial automation, electric power automation, remote medical operation, traffic safety guarantee, and the like.

3) mMTC scenario: typical features of URLLC include: high connection density, small data volume, time delay insensitive service, low cost of the module, long service life and the like.

In NR, the power level of a terminal is generally 23dBm by default, and the terminal supports a high power level of 26dBm in order to enable good uplink coverage at the edge of a cell or in an environment with poor channel conditions. Currently, the support of the high power class by the UE is an optional characteristic of the UE, and the high power class is supported only on 4 frequency bands (bands), and a default power class, namely a 23dBm power class, is supported in other cases.

Considering user radiation and other factors, it is necessary to limit the ratio of UpLink (UL) transmission time for a UE supporting a power class of 26 dBm. The ratio of UL transmission time is a ratio of UL transmission time to predetermined time within a predetermined time. For this reason, the UE needs to report the fraction of the maximum UL transmit time supported. If the network side scheduling exceeds the UE's fractional capability with respect to UL transmission time, the UE drops back to a default power level, e.g., 23 dBm.

Fig. 2 is a schematic flow chart of an information transmission method provided in an embodiment of the present application, and as shown in fig. 2, the information transmission method includes the following steps:

step 201: and when the terminal determines that the power level changes, sending a first message to network equipment, wherein the first message comprises the PHR and/or the power level of the terminal.

In the embodiment of the application, the terminal can be any equipment which can communicate with a network, such as a mobile phone, a tablet computer, a notebook computer, a desktop computer and the like.

In this embodiment of the present application, the network device may be a base station, for example, a gbb in 5G.

In the embodiment of the present application, the change of the power level of the terminal means: the power level of the terminal changes from one power level to another, for example: change from default power level (23dBm) to high power level (26dBm), again for example: from the high power level (26dBm) to the default power level (23 dBm).

In the embodiment of the application, when the power level of the terminal changes, a first message is sent to a network device, and the first message includes a PHR and/or the power level of the terminal.

Here, PHR refers to a power headroom report, and the role of PHR is that a terminal reports a power headroom to a network, and the value of the power headroom is transmitted by a Control Element (CE) of a Media Access Control (MAC) layer, and the MAC CE for transmitting the PHR is also referred to as a PHR Control element. The power headroom is a difference between the maximum transmission power allowed by the UE and the currently estimated transmission power of the Physical Uplink Shared Channel (PUSCH). The power headroom is how much transmission power the UE can use in addition to the transmission power used for the current PUSCH transmission. The unit of the power headroom is dB, the range is [ -23dB, +40dB ], if it is negative, it means that the network side schedules a data transmission rate to the UE that is higher than the one that can be supported by its currently available transmit power.

Here, the power level of the terminal corresponds to one power value, for example, the default power level is 23dBm, and the high power level is 26 dBm.

In the embodiment of the present application, when the power level of the terminal changes, the information sent to the network device through the first message has the following situations:

1) the first message comprises a PHR;

2) the first message includes a PHR and a power class of the terminal; here, the power level of the terminal may be transmitted in the form of a PHR;

3) the first message includes a PHR including a power class of the terminal;

4) the first message includes a power class of the terminal, where the first message is RRC signaling or MAC CE.

In the embodiment of the present application, the power level of the terminal changes, which can be implemented in the following manner:

1) the terminal adjusts a power level of the terminal based on the channel quality.

In an embodiment, in a state that the power level of the terminal is at a first power level, if it is detected that the channel quality is less than or equal to or less than a first threshold, the terminal triggers adjustment of the power level of the terminal to a second power level, where the second power level is greater than the first power level. Here, the first threshold is configured by the network device, for example, the network device sends the first threshold to the terminal through system broadcast or dedicated signaling.

In another embodiment, if the power level of the terminal is in a second power level state and it is detected that the channel quality is greater than or equal to or greater than a second threshold value, the terminal triggers adjusting the power level of the terminal to a first power level, where the second power level is greater than the first power level. Here, the second threshold is configured for the network device, for example, the network device sends the second threshold to the terminal through system broadcast or dedicated signaling.

For example: the UE may adjust the UE power level based on the channel environment (e.g., the channel quality measured by the UE). Assuming that the current power level of the UE is a default power level, that is, 23dBm, if it is detected that the channel quality is lower than the threshold 1, the UE triggers to change the power level of the UE to 26dBm, otherwise, the UE uses the default power level, that is, 23 dBm. Further, assuming that the current power level of the UE is 26dBm, if it is detected that the channel quality is higher than the threshold 2, the UE triggers to change the power level of the UE to 23 dBm. Here, threshold 1 and threshold 2 depend on network side configuration, such as system broadcast or dedicated signaling.

2) The terminal adjusts the power level of the terminal based on a second message sent by the network equipment, wherein the second message is used for indicating the power level which needs to be adjusted by the terminal.

Specifically, the second message is triggered and sent to the terminal by the network device based on an uplink measurement result or an uplink decoding block error rate (BLER).

In an embodiment, the second message is RRC signaling, or MAC CE, or PDCCH order.

a determining unit 301, configured to determine that a power level changes;
