Description

Data transmission processing method and device and storage medium

Technical Field

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

Background

In the related art, if a User Equipment (UE) is switched from a radio resource control non-connected (RRC _ unconnected) state to a connected (RRC _ connected) state, much signaling overhead is required. When the ue has small data to transmit, it also needs to transition from RRC _ inactive state to RRC _ connected state and then transmit the small data, which is not favorable for saving power of the ue.

In 3GPP R17, in order to enable power saving for a user equipment, it is proposed that a small data transmission/reception possibility is possible for a user equipment in an inactive state under radio resource control. However, how to use the random access procedure to achieve small data transmission in the existing initial access procedure to reduce the bit overhead or to be compatible with the random access procedure in the related art as much as possible is a technical problem to be further solved by the prior art.

For example, as shown in fig. 2, a method flow diagram of a four-step random access procedure is disclosed; the method comprises the following steps:

Step S31: sending a random access leader sequence;

in an embodiment, the ue sends the random access preamble sequence to the base station.

Step S32: receiving random access response information;

in an embodiment, the ue receives random access response information returned by the base station based on the random access preamble sequence.

In the two random access procedures shown in fig. 2 and fig. 3, there is no provision for the transmission of data frames and the resources for transmitting the data frames, so that enhancement is required.

As shown in fig. 4, an embodiment of the present disclosure provides a data transmission processing method, where the method includes the following steps:

step S41, receiving a random access leader sequence sent by the user equipment;

step S42, if the random access preamble sequence is a predetermined sequence, receiving a data frame sent by the user equipment in the random access process.

The data transmission processing method in the embodiment of the disclosure is applied to a base station. Here, the base station is an interface device for the user equipment to access the internet. The base station may be various types of base stations, for example, a 3G base station, a 4G base station, or a 5G base station.

Here, the user device may be a mobile phone, a computer, a server, a transceiving device, a tablet device or a medical device, etc.

In this embodiment, the ue is in a non-connected state. Here, the unconnected state includes: an idle state, or an inactive state.

In some embodiments, the number of bits of the data frame is less than a predetermined value.

Here, in the random access procedure, the data frame to be transmitted is a frame in which the number of bits is less than a predetermined value. For example, the data frame may be a size of less than 72 bits, or 56 bits, or other designated bits of data frame. As such, in this example, the user equipment in the inactive state can be made to transmit small data, thereby making the user equipment more power efficient.

Of course, in other embodiments, the number of bits of the data frame is greater than a predetermined value.

In some embodiments, the step S42 includes:

if the random access preamble sequence is a predetermined sequence,

sending random access response information carrying resource information to the user equipment;

Here, the random access procedure may be the 4-step random access procedure described above.

Here, a method for sending random access response information carrying resource information to the ue includes: and sending the MSG2 to the user equipment, wherein the MSG2 carries the random access response information.

Here, the resource information includes: time domain and/or frequency domain resource information. In an embodiment, the resource information is information of a time-frequency domain resource location.

In some embodiments, the predetermined sequence comprises: a random access preamble sequence of a predetermined format.

Here, a format of the predetermined format is different from a format of a random access preamble sequence transmitted by the user equipment when data is not transmitted.

In this way, in this embodiment, the user equipment configures the random access preamble sequence into a predetermined format, so that when the base station receives the random access preamble sequence, it knows that the user equipment will transmit a data frame in a random access procedure. Further, the random access preamble sequence is different from a preamble sequence transmitted in a 4-step RACH or a 2-step RACH by a UE defined in an existing standard, so that a base station allocates resources for the user equipment, transmits resource information to the user equipment, and allows the user equipment to transmit a data frame to the base station based on the resources.

In other embodiments, the step S42 includes: and receiving the data frame sent by the user equipment within a preset time range of the preset time when the preset sequence is received.

Here, the random access procedure may be a 2-step random access procedure.

In practical applications, the predetermined time is different from the time when the random access preamble sequence is transmitted as in fig. 2 or fig. 3.

In one embodiment, the predetermined sequence comprises: a random access preamble sequence received at a predetermined time.

Here, the predetermined time is different from a time used by the user equipment to transmit the random access preamble sequence when not transmitting data.

In one embodiment, the method comprises: transmitting predetermined time information to the user equipment.

Thus, in this embodiment, the base station configures, for the ue, a predetermined time for sending the random access preamble sequence; as such, the user equipment may transmit the random access preamble sequence for a predetermined time. When the base station receives the random access preamble sequence received within the range of the preset opportunity, the base station knows that the user equipment will send the data frame in the random access process. In this way, the base station will receive the data frame sent by the user equipment within the predetermined time range of the predetermined time.

Of course, in this embodiment, if the base station receives the random access preamble sequence with the predetermined format, the base station may also know that the ue sends the data frame in the random access process.

It is to be understood that, whether in 4-step, 2-step, or other random access procedure, if the base station receives a random access preamble sequence of a predetermined format or a random access preamble received at a predetermined time, the base station knows that the user equipment will transmit a data frame in the random access procedure. For example, if the random access procedure is a 4-step random access procedure, the data frame carried in the MSG3 sent by the user equipment may be received. For another example, if the random access procedure is a 2-step random access procedure, the data frame carried by a Physical Uplink Shared Channel (PUSCH) in a random access message a (msga) sent by the user equipment may be received.

In the embodiment of the disclosure, a random access preamble sequence sent by user equipment is received; and if the random access preamble sequence is a predetermined sequence, receiving a data frame sent by the user equipment in the random access process. Therefore, the embodiment of the disclosure can know that the user equipment uploads the data frame in the random access process by receiving the random access preamble sequence of the predetermined sequence, so that the user equipment is informed of the data frame transmission without extra signaling, the signaling overhead can be reduced, and the electric quantity of the user equipment can be saved.

The data transmission in the random access process does not introduce special information in the random access process to indicate that data needs to be transmitted, namely the random access process in the related technology is little reformed, and the method has the characteristic of strong compatibility with the related technology.

In some embodiments, the step S41 includes:

Here, the identification information of the user equipment includes, but is not limited to, one of: a cell radio network temporary identity (C-RNTI), and an indicator radio network temporary identity I-RNTI.

In an embodiment, the time domain resource for receiving the random access preamble sequence and the identification information is different.

In another embodiment, the frequency domain resource in which the random access preamble sequence is received is different from the frequency domain resource in which the identification information is received.

In the embodiment of the present disclosure, the random access preamble sequence is sent to the base station together with the identification information of the UE. One implementation manner is that based on different time domain resources, MSG3 carrying random access preamble sequences and UE identification information is sent; in this way, the random access preamble sequence and the identification information of the UE have a predetermined time threshold in the time domain. The other realization mode is that the MSG3 carrying the random access preamble sequence and the identification information of the UE is sent based on the same time domain resource and different frequency domain resources; in this way, the random access preamble sequence and the identification information of the UE are simultaneously transmitted in different frequency domain resources.

Thus, in the embodiment of the present disclosure, the base station can be made aware of the ue that needs to configure the resource and the ue that sends the data frame. And, the identification information of the user equipment is sent together with the MSG3, which can greatly reduce the signaling overhead.

It will be appreciated that the above embodiments may be applied to a 4-step random access procedure or to a 2-step random access procedure.

In some embodiments, the method further comprises:

In the embodiment of the present disclosure, the identification information of the user equipment may also be carried in MSG3 for transmission. In this way, the base station can be made aware of the user equipment that sent the data frame.

In some embodiments, the receiving the data frame sent by the user equipment includes:

In the embodiment of the present disclosure, the identification information of the user equipment may also be received while receiving the data frame; in this way, the transmission of signaling can be reduced, and the base station is made aware of the user equipment that allocated resources or the user equipment that sent the data frame.

In some embodiments, receiving the data frame carrying the identification information of the user equipment sent by the user equipment includes:

In an embodiment, the receiving the data frame carrying the identification information of the user equipment sent by the user equipment includes: and receiving a random access message A (MSGA) which is sent by the user equipment and carries the data frame and the identification information.

Here, the random access message a is transmitted based on a physical upload shared channel.

Here, the MSGA is transmitted after the user equipment transmits the random access preamble sequence. Here, the random access procedure of this embodiment is a 2-step random access procedure.

In the embodiment of the present disclosure, the identification information of the user equipment may be transmitted together with the data frame, so that the base station knows the user equipment transmitting the data frame or the user equipment only needing to allocate resource information.

In some embodiments, the predetermined sequence is indicative of at least one of:

the user equipment sends a Modulation and Coding Scheme (MSC) mode of the data;

the base station returns the bit number of an Acknowledgement Character (ACK);

In this embodiment of the present disclosure, the predetermined sequence is further used to indicate a modulation and coding scheme of data transmitted by the user equipment. In this way, the modulation and coding scheme used by the base station to receive the data frame sent by the user equipment in the random access process may be the same as the modulation and coding scheme used to receive the data frame sent by the user equipment in the random access process. For example, the modulation and coding scheme for the user to send the data frame in the inactive state is the same as the modulation and coding scheme for the user to send the data frame in the active state. For another example, the modulation and coding scheme for transmitting the data frame based on MSG3 is the same as the modulation and coding scheme for transmitting the data frame based on random access message a.

In an embodiment of the present disclosure, the predetermined sequence is further used to indicate a number of bits of the confirmation character. Here, the number of bits of the confirmation character is smaller than a predetermined value. For example, the predetermined value is 2 or 3. And if the base station receives the data frame sent by the user equipment and returns the data frame with the preset bit number, the data frame with the preset bit number is the confirmation character of the data frame sent by the user equipment. As such, the user equipment knows that the base station has received a data frame.

In an embodiment of the present disclosure, the predetermined sequence is further used to indicate resource information used by the confirmation character. For example, in the four-step random access process, the base station sends MSG2 carrying the resource information used by the acknowledgement character. As such, embodiments of the present disclosure may enable the user equipment to receive the confirmation character based on the allocated resources.

Here, it should be noted that: the following description of a data transmission method is applied to a user equipment, and is similar to the above description of the data transmission method applied to a base station. For technical details that are not disclosed in the embodiments of the method for transmitting data applied to the ue in the present disclosure, please refer to the description of the embodiments of the method for transmitting data applied to the base station in the present disclosure, which will not be described in detail herein.

As shown in fig. 5, the present embodiment discloses a data transmission processing method, which includes the following steps:
