Description
Technical Field
The present application 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 is generated on human bodies under the action of an electromagnetic field. Various national agencies, such as the federal communications commission in the united states and the international non-ionizing radiation protection commission, impose restrictions on the radio frequency radiation from the terminal devices to prevent the ionizing radiation generated by the terminal devices from causing harm to human bodies. Generally, terminal devices with operating frequencies lower than 6GHz use a Specific Absorption Rate (SAR) to evaluate the influence of ionizing radiation on the human body; in the terminal equipment higher than 6GHz, since the frequency of the electromagnetic wave is high and the penetration effect of the electromagnetic wave is poor, the Maximum Permissible Exposure (MPE) is generally used to evaluate the influence of the ionizing radiation on the human body.
In a wireless communication system standard, such as The 5th Generation (5G) communication system established by The 3rd Generation Partnership Project (3 GPP), in order to avoid that The ionizing radiation generated by The terminal device is too large to exceed The regulatory requirements of each country, The terminal device may limit The maximum transmission power of The terminal device through a power management (power management) maximum output power reduction (MPR), i.e., a parameter P-MPR, so as to reduce The SAR or MPE of The terminal device, thereby achieving The purpose of meeting The regulatory requirements. Since the P-MPR is autonomously controlled and set by the terminal device, if the terminal device sets a larger P-MPR, a radio link failure may be caused, and then the terminal device needs to perform Radio Resource Control (RRC) reestablishment and other procedures. When the terminal device operates in frequency range 2(frequency range2, FR2), the frequency of radio link failures is more severe. For this reason, the R16 protocol is considering new introduced energy margin (energy headroom), and the terminal device reports the energy margin not exceeding the regulation to the network device according to its own radiation condition; and correspondingly scheduling resources by the network equipment so that the ionizing radiation of the terminal equipment does not exceed the requirements of the regulations. Meanwhile, the R16 protocol considers that the terminal device reports the P-MPR as described above, so as to meet the requirement of the regulation.
However, how the terminal device reports the P-MPR or the energy margin has no clear solution.

Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the term using examples is intended to present concepts in a concrete fashion.
The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.
At present, 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 the 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 (RRC) reestablishment procedure. When the terminal device operates in frequency range 2(frequency range2, FR2), the frequency of radio link failures is more severe.
For this reason, 3GPP is developing 5G R16 protocol, and in order to solve the problem that when the terminal device operates under FR2, the terminal device sets a large P-MPR, which causes radio link failure and connection release, it is considered that the terminal device actively reports auxiliary information, which may be P-MPR or energy margin, etc. Therefore, an embodiment of the present application provides a method for reporting a P-MPR or an energy headroom. It should be noted that, in this embodiment of the present application, the energy margin may refer to a difference between a maximum transmission energy allowed by the terminal device within a period of time and a transmission energy that has been used by the current terminal device.
The specific time length of the "period of time" is not limited in the embodiments of the present application, and may be set according to an actual situation, which is not described herein again.
In this embodiment, the P-MPR or the energy headroom is sent through a Media Access Control (MAC) Control Element (CE) in a MAC PDU. One MAC PDU includes at least one MAC sub (sub) PDU, where one MAC sub PDU includes at least a MAC sub header, and may further include 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 headroom, the MAC CE may be referred to as a P-MPR MAC CE or an energy headroom MAC CE, and for convenience of description, the MAC CE is simply referred to as a first MAC CE in the following description.
With reference to fig. 2, a schematic flow chart of a data transmission method according to an embodiment of the present application is provided in conjunction with the foregoing description.
The method comprises the following steps:
step 201: the terminal equipment determines a first parameter, wherein the first parameter is P-MPR or 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.
It should be noted that, as described above, the first MAC CE is transmitted in the MAC PDU.
Step 203: the network device receives the first MAC CE from the terminal device.
Wherein 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 to control the uplink transmission of the terminal device is specifically controlled by the network device, which is not limited in the embodiments of the present application and is not described herein again.
It should be noted that, 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 may be reconfigured into a new format, 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 equipment can assemble the data of different logical channels into one MAC PDU in a multiplexing mode.
The total amount of data that can be transmitted by the terminal device is determined according to the resource scheduled by the network device, and the terminal device may not transmit all data to be transmitted through the MAC PDU at one time.
The logical channel priority of the current MAC CE may be from high to low in the following order:
1. a MAC CE for a cell radio network temporary identifier (C-RNTI) or data from an uplink-common control channel (UL-CCCH);
2. a MAC CE for Semi Persistent Scheduling (SPS) configuration authorization confirmation;
3. a MAC CE for BSRs other than a Buffer Status Report (BSR);
4. a MAC CE for a 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 except for data of UL-CCCH;
6. a MAC CE for 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 implementation manners of the logical channel priority of the first MAC CE, which are described below separately.
For example, in a possible implementation manner, since the BSR is used to inform 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 scheduling of the terminal, so if the BSR cannot normally transmit and receive, the network cannot effectively schedule the terminal. Therefore, the BSR is a basic function of the uplink data service, and has a large impact on uplink performance and uplink experience, and for this reason, 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 used for BSRs other than the padding buffer status report BSR.
In addition, the MAC CE used for the PHR or the extended PHR or the single-entity PHR or the multi-entity PHR, hereinafter referred to as the third MAC CE, is configured to report the power headroom of the terminal device, so as to assist the network in performing adaptive modulation and coding and power control. The first MAC CE mainly informs the network of the SAR/MPE restriction, and if the restriction is serious and the first MAC CE is not transmitted in time, serious influences such as a radio link failure may be immediately caused. In contrast, the third MAC CE is not transmitted in time and does not immediately cause 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 reason, the logical channel priorities of different MAC CEs may be changed from high to low in the following order:
1. MAC CE for C-RNTI or data from UL-CCCH;
2. MAC CE used for confirming the configuration authorization of semi-persistent scheduling;
3. a MAC CE for BSRs other than padding BSRs;
4. a MAC CE for carrying a P-MPR or an energy margin, i.e., a first MAC CE;
5. a MAC CE for a PHR or an extended PHR or a single-entity PHR or a multi-entity PHR;
6. a MAC CE for data from any logical channel except for data of UL-CCCH;
7. a MAC CE for recommending bit rate queries;
8. MAC CE for padding BSR.
For example, in another possible implementation, first, the logical channel priority of the first MAC CE may be lower than the logical channel priority of the second MAC CE.
Secondly, the third MAC CE can play a role in assisting network adaptive coding modulation in various scenarios, but the first MAC CE generally has a larger role in SAR/MPE limitation, and therefore 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 except for data of UL-CCCH.
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 reason, the logical channel priorities of different MAC CEs may also be changed from high to low in the following order:
1. MAC CE for C-RNTI or data from UL-CCCH;
2. MAC CE used for confirming the configuration authorization of semi-persistent scheduling;
3. a MAC CE for BSRs other than padding BSRs;
4. a MAC CE for a PHR or an extended PHR or a single-entity PHR or a multi-entity PHR;
5. a MAC CE for carrying a P-MPR or an energy margin, i.e., a first MAC CE;
6. a MAC CE for data from any logical channel except for data of UL-CCCH;
7. a MAC CE for recommending bit rate queries;
8. MAC CE for padding BSR.
Of course, the above is only an example, and the logical channel priority of the first MAC CE may be determined in other situations, which are determined according to practical situations, and are not illustrated in sequence here.
The various embodiments described herein may be implemented as stand-alone solutions or combined in accordance with inherent logic and are intended to fall within the scope of the present application.
