Description

Data transmission method and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a data transmission method and apparatus.

Background

When the terminal equipment receives and transmits data in a wireless mode, ionizing radiation can be generated on a human body under the action of an electromagnetic field. Various national authorities, such as the federal communications commission and the international non-ionizing radiation protection commission, etc., impose restrictions on radio frequency radiation from terminal equipment, avoiding harm to the human body caused by ionizing radiation generated by the terminal equipment. In general, terminal devices with operating frequencies below 6GHz all use electromagnetic wave absorption ratios (specific absorption rate, SAR) to evaluate the effect of ionizing radiation on the human body; terminal equipment above 6GHz, due to the higher frequency of electromagnetic waves, has a relatively poor penetration of electromagnetic waves, and the effect of ionizing radiation on the human body is generally evaluated with maximum permissible exposure (maximum permissible exposure, MPE).

In a wireless communication system standard, for example, a 5th generation mobile communication (The 5th generation,5G) communication system formulated by a third generation partnership project (The 3rd Generation Partnership Project,3GPP), in order to avoid that ionizing radiation generated by a terminal device is too large to exceed regulatory requirements of various countries, the terminal device can limit The maximum transmission power of The terminal device through maximum output power backoff (max output power reduction, MPR) of power management (power management), i.e., parameter P-MPR, so as to reduce SAR or MPE of The terminal device, and achieve The purpose of meeting regulatory requirements. Since the P-MPR is autonomously controlled and set by the terminal device, if the terminal device sets a larger P-MPR, it may cause a radio link failure, and then the terminal device needs to perform a procedure such as radio resource control (radio resource control, RRC) reestablishment. When the terminal device operates in the frequency range2 (FR 2), the frequency of occurrence of the radio link failure is more serious. For this purpose, the R16 protocol is considering newly introduced energy headroom (energy headroom), and the terminal device reports the energy headroom without exceeding the regulation to the network device according to the radiation condition of the terminal device; the network device schedules resources accordingly so that the ionizing radiation of the terminal device does not exceed regulatory requirements. Meanwhile, the R16 protocol also takes the terminal equipment into consideration to report the P-MPR as described above, so as to achieve the purpose of meeting the requirement of regulations.

However, there is no clear solution for how the terminal device reports the P-MPR or the energy margin.

Rather, the term use of an example is intended to present concepts in a concrete fashion.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

Currently, in order to avoid excessive ionizing radiation generated by the terminal device, if the terminal device detects that the transmission power needs to be reduced, the terminal device may reduce the transmission power by setting P-MPR. Since the P-MPR is autonomously controlled and set by the terminal device, if the terminal device sets a larger P-MPR, it will cause radio link failure, and then the terminal device needs to perform a radio resource control (radio resource control, RRC) reestablishment procedure. When the terminal device operates in the frequency range2 (FR 2), the frequency of occurrence of the radio link failure is more serious.

For this reason, 3GPP is developing 5g r16 protocol, so as to solve the problem that when the terminal device works under FR2, the terminal device sets a larger P-MPR, which results in radio link failure and connection release, and consider that the terminal device actively reports auxiliary information, which may be P-MPR or energy margin. Therefore, the embodiment of the application provides a P-MPR or energy margin reporting method. It should be noted that, in the embodiment of the present application, the energy margin may refer to a difference between the maximum transmission energy allowed by the terminal device and the transmission energy already used by the current terminal device.

The embodiment of the present application is not limited to a specific time length of "a period of time", and may be set according to actual situations, which is not described herein.

In the embodiment of the present application, the P-MPR or the energy margin is transmitted through a media access control (medium access control, MAC) Control Element (CE) in a MAC protocol data unit (protocol data unit, PDU). One MAC PDU comprises at least one MAC sub (sub) PDU, wherein one MAC sub PDU at least comprises a MAC sub header and can also comprise contents such as a MAC CE. When the MAC CE in the MAC sub PDU is used to carry the P-MPR or the energy margin, the MAC CE may be referred to as a P-MPR MAC CE or an energy margin MAC CE, and for convenience of description, in the following description, the MAC CE is simply referred to as a first MAC CE.

With reference to fig. 2 in combination with the foregoing description, a flow chart of a data transmission method according to an embodiment of the present application is provided.

The method comprises the following steps:

step 201: the terminal device determines a first parameter, which is P-MPR or an energy margin.

Step 202: and the terminal equipment sends the first MAC CE according to the logic channel priority of the first MAC CE carrying the first parameter.

As described above, the first MAC CE is transmitted in a MAC PDU.

Step 203: the network device receives a first MAC CE from the terminal device.

The first MAC CE is used for carrying a first parameter.

Step 204: and the network equipment controls the uplink transmission of the terminal equipment according to the first parameter in the first MAC CE.

How the network device specifically controls the uplink transmission of the terminal device is not limited in this embodiment, and will not be described herein.

In the embodiment of the present application, the format of the first MAC CE may be multiplexed with the format of the MAC CE in the prior art, or a new format may be reset, which is not limited in the embodiment of the present application.

In the prior art, the MAC layer is responsible for multiplexing multiple logical channels (logical channels) onto the same transport channel (transport channel). Therefore, the terminal device can assemble the data of different logic channels into one MAC PDU in a multiplexing mode.

The total amount of data that the terminal device can send is determined according to the resources scheduled by the network device, the terminal device may not be able to send all the data that needs to be sent through the MAC PDU at a time, for which purpose, the terminal device may determine which MAC CEs are carried in the MAC PDU according to the logical channel priority of each MAC CE in the process of assembling the MAC PDU.

The logical channel priorities of the MAC CEs at present may be in the following order from high to low:

1. a MAC CE for a cell radio network temporary identifier (cell radio network tempory identity, C-RNTI) or data from an uplink common control channel (UL-common control channel, UL-CCCH);

2. a MAC CE for semi-persistent scheduling (semi persistent scheduling, SPS) configuration grant confirmation (configured grant confirmation);

3. MAC CE for BSR other than padding buffer status report (buffer status report, BSR);

4. a MAC CE for a power headroom report (power headroom report, PHR) or an extended PHR or a single entity PHR or a multi-entity PHR;

5. a MAC CE for data from any logical channel other than UL-CCCH data;

6. a MAC CE for a recommended bit rate query (recommended bit rate query);

7. MAC CE for padding BSR.

In this embodiment of the present application, there may be multiple implementations of the logical channel priority of the first MAC CE, which are described below.

In one possible implementation, the BSR informs the network of the size of its buffer, if the buffer is large, the network may increase uplink scheduling of the terminal, and if the buffer is 0, the network does not need to continue to schedule the terminal, so if the BSR cannot send and receive normally, the network cannot schedule the terminal effectively. The BSR is thus the basic function of the uplink data traffic, with a large impact on uplink performance and uplink experience, for which the logical channel priority of the first MAC CE may be lower than the logical channel priority of the second MAC CE, which is the MAC CE for BSR other than the padding buffer status report BSR.

In addition, the MAC CE used for PHR or extended PHR or single-entity PHR or multi-entity PHR, hereinafter referred to as the third MAC CE for short, is used for reporting the power headroom of the terminal device, thereby assisting the network in performing adaptive modulation coding and power control. The first MAC CE mainly informs the network of the SAR/MPE limitation, and if the limitation is severe and the first MAC CE is not transmitted in time, the first MAC CE may immediately cause serious effects such as radio link failure. In contrast, the third MAC CE is not transmitted in time and does not immediately have a serious impact. Thus, in this implementation, the logical channel priority of the first MAC CE may be higher than the logical channel priority of the third MAC CE.

In summary, in this implementation, the logical channel priority of the first MAC CE may be lower than the logical channel priority of the second MAC CE and may be higher than the logical channel priority of the third MAC CE. For this purpose, the logical channel priorities of different MAC CEs may be changed from high to low into the following order:

1. MAC CE for C-RNTI or data from UL-CCCH;

2. a MAC CE for semi-persistent scheduling configuration grant confirmation;

3. MAC CEs for BSR other than padding BSR;

4. A MAC CE for carrying a P-MPR or an energy headroom, i.e., a first MAC CE;

5. MAC CEs for PHR or extended PHR or single-entity PHR or multi-entity PHR;

6. a MAC CE for data from any logical channel other than UL-CCCH data;

7. a MAC CE for recommending bit rate queries;

8. MAC CE for padding BSR.

In another possible implementation, the logical channel priority of the first MAC CE may be lower than the logical channel priority of the second MAC CE.

Second, the third MAC CE can play a role in assisting the network adaptive code modulation in various scenarios, but the first MAC CE will generally have a larger effect on the SAR/MPE limited situation, so in this implementation, the logical channel priority of the third MAC CE may also be greater than the logical channel priority of the first MAC CE.

On the other hand, the first MAC CE may belong to power control related signaling and may have a higher priority than the fourth MAC CE. Wherein the fourth MAC CE is a MAC CE for data from any logical channel other than UL-CCCH data.

In summary, in this implementation, the logical channel priority of the first MAC CE may be lower than the logical channel priority of the third MAC CE and may be higher than the logical channel priority of the fourth MAC CE. For this purpose, the logical channel priorities of different MAC CEs may also be changed from high to low to the following order:

1. MAC CE for C-RNTI or data from UL-CCCH;

2. a MAC CE for semi-persistent scheduling configuration grant confirmation;

3. MAC CEs for BSR other than padding BSR;

4. MAC CEs for PHR or extended PHR or single-entity PHR or multi-entity PHR;

5. a MAC CE for carrying a P-MPR or an energy headroom, i.e., a first MAC CE;

6. a MAC CE for data from any logical channel other than UL-CCCH data;

7. a MAC CE for recommending bit rate queries;

8. MAC CE for padding BSR.

Of course, the above is merely an example, and the logical channel priority of the first MAC CE may be other cases, specifically determined according to the actual situation, which are not illustrated one by one.

The various embodiments described herein may be separate solutions or may be combined according to inherent logic, which fall within the scope of the present application.

It should be understood that, in the foregoing embodiments of the methods and operations implemented by the terminal device, the methods and operations implemented by the network device may also be implemented by a component (e.g., a chip or a circuit) that may be used in the terminal device, or the methods and operations implemented by the network device may also be implemented by a component (e.g., a chip or a circuit) that may be used in the network device.
