Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In a mobile communication system, when a network device schedules an uplink grant resource corresponding to a PUSCH to a terminal device, the terminal device needs to send a data packet in the PUSCH. In some scenarios, when there is no data to be transmitted in the terminal device, the network device may still schedule uplink grant resources corresponding to the PUSCH to the terminal device, and the terminal device may assemble a null packet and transmit the null packet in the PUSCH. Such as a Voice over Long-Term Evolution (VoLTE) scenario. At this time, the terminal device may transmit a large number of invalid null packets, increasing the power consumption of the terminal device.

The third Generation Partnership project (3 rd Generation Partnership project,3 gpp) protocol specifies that in a mobile communication system, when a network device Semi-Persistent Scheduling (SPS) uplink grant resource, a terminal device may release the uplink grant resource scheduled by the network device to a PUSCH when the terminal device continuously transmits N null packets not carrying SDUs in the PUSCH. However, when the network device dynamically schedules the uplink grant resource, the terminal device needs to send a data packet in the PUSCH as long as the network device schedules the uplink grant resource corresponding to the PUSCH to the terminal device. When no data needs to be sent in the terminal equipment, the terminal equipment assembles a null packet and sends the null packet in a PUSCH. At this time, the terminal device may assemble a large number of null packets to be transmitted to the network device, resulting in an increase in power consumption of the terminal device.

Based on this, the embodiment of the present application provides a data processing method, an apparatus, and a terminal device, in the data processing method, the terminal device may acquire a PUSCH, and when the number of subframes not carrying SDU in the PUSCH is greater than or equal to N, discard an empty packet sent on a subframe not carrying SDU except N subframes in the PUSCH. And a large number of empty packets which do not bear SDU can be prevented from being sent in the PUSCH, and the power consumption of the terminal equipment is saved.

The data processing method of the embodiment of the application can be applied to a network system, and the network system can be a mobile communication system. Referring to fig. 1, fig. 1 shows an architecture diagram of a network system. As shown in fig. 1, the network system may include a terminal device 10 and a network device 20. The terminal device 10 and the network device 20 are communicatively connected, for example, the terminal device 10 may establish a communication connection with the network device 20 through a Global System for Mobile Communications (GSM), general Packet Radio Service (GPRS), code Division Multiple Access (CDMA), wideband Code Division Multiple Access (WCDMA), time Division Multiple Access (Time-Division Multiple Access, TD-SCDMA), long Term Evolution (LTE), fifth Generation Mobile communication technology (5 th Generation Mobile communication, 5 g), wireless Local Area Network (WLAN), wireless Fidelity (Wi-Fi) network. Moreover, with the rapid development of the internet of things technology, the terminal device 10 may also establish a communication connection with the network device 20 through the internet of things technology. For example, the terminal device 10 may establish a Communication connection with the network device 20 through Machine Type Communication (MTC), narrowband Band Internet of Things (NB-IoT), and so on. The embodiment of the present application does not limit this.

The terminal device 10 may be a portable terminal device, such as a smart phone, a tablet computer, a wearable terminal device with a wireless communication function (e.g., a smart watch, a laptop computer), and the like; the terminal device 10 may also be a non-portable terminal device such as a vehicle-mounted computer, a desktop computer, or the like.

Here, the network device 20 refers to a device that can provide a wireless communication function for the terminal device 10. The Network device 20 may be a next generation Base Station (enode B, gNB), an evolved Node B (evolved Node B, eNB), a Node B (Node B, eNB), a Radio Network Controller (Radio Network Controller, RNC), a Base Station Controller (Base Station Controller, BSC), a Base Transceiver Station (BTS), a Base Band Unit (BBU), a transmission Point (TRP), a Transmission Point (TP), a mobile switching center, etc. in 5G, which are not limited herein.

Next, the data processing method of the embodiment of the present application will be explained in detail. Referring to fig. 2, fig. 2 is a flow chart illustrating a data processing method. The data processing method can be applied to the terminal device shown in fig. 2. As shown in fig. 2, the data processing method specifically includes S201 to S202:

s201: and acquiring the PUSCH sent by the terminal equipment.

The PUSCH may be used to carry data packets. Optionally, the network device may send Downlink Control Information (DCI) through a Physical Downlink Control Channel (PDCCH), and the terminal device receives and analyzes the DCI to obtain a subframe corresponding to a PUSCH, and sends a data packet carried by the PUSCH by using the subframe corresponding to the PUSCH. The subframe corresponding to the PUSCH may refer to an uplink grant resource corresponding to the PUSCH, or the subframe corresponding to the PUSCH may also refer to a time domain resource corresponding to the PUSCH.

Optionally, the network device may also issue response information, for example, an Acknowledgement (ACK) or a Negative Acknowledgement (NACK), through a Physical Hybrid ARQ Indicator Channel (PHICH), and the terminal device may retransmit the data packet in a subframe corresponding to the PUSCH in response to the response information.

In one embodiment, the data packets may include two types: data packets containing SDUs and data packets not containing SDUs (i.e., null packets). Therefore, the subframe corresponding to the PUSCH may be divided into two types based on the type of the data packet: a first type of subframe and a second type of subframe. The first type of subframe may refer to a subframe that does not carry an SDU in the PUSCH (i.e., a subframe that does not contain an SDU data packet). The second type subframe may refer to a subframe carrying an SDU in the PUSCH (i.e., a subframe containing an SDU data packet). The SDU may refer to an SDU provided by the Multiplexing and Assembly entity (the Multiplexing and Assembly entity).

It should be noted that, when scheduling the uplink grant resource, the network device may also schedule a third type subframe to the terminal device, where the third type subframe is a subframe other than the PUSCH bearer subframe in the time domain resource. For example, the third type subframe scheduled by the network device for the terminal device is a subframe corresponding to a Physical Uplink Control Channel (PUCCH).

S202: when the PUSCH has N subframes and does not bear SDU, the terminal equipment determines to discard the empty packet sent on the subframe which does not bear the SDU except the N subframes in the PUSCH, wherein N is a positive integer.

When the terminal equipment does not transmit data, the terminal equipment can assemble a large number of null packets to be transmitted in the PUSCH, so that the power consumption of the terminal equipment is increased. Therefore, in order to save the power consumption of the terminal device, the terminal device may determine to discard the null packet in the PUSCH according to the subframe in the PUSCH which does not carry the SDU. Specifically, the terminal device may obtain the number of subframes which do not carry SDU (i.e., first type subframes) in the PUSCH, and when the number of the first type subframes is greater than or equal to N, the terminal device may determine to discard an empty packet sent on the subframe which does not carry SDU in the PUSCH, where N is a positive integer. Optionally, N may be set according to experience or business requirements. Optionally, N may also be determined based on the RRC configuration parameter implicitReleaseAfter.

Further, since the subframe of the PUSCH may also be used to carry UCI. When only a Data packet (UL-SCH-Data) is on a subframe corresponding to the PUSCH, the terminal device can transmit the UL-SCH-Data in the subframe through the PUSCH. If UCI still exists on the subframe corresponding to the PUSCH, the terminal equipment can carry the UL-SCH-Data and the UCI in the subframe to be transmitted in the PUSCH.

Based on this, in order to avoid discarding valid information, in an embodiment, when there are N subframes of the PUSCH, none of which carries SDU, the terminal device may schedule the physical layer to determine one or more subframes, other than the N subframes, in the PUSCH, which do not carry SDU, and if one or more subframes do not carry UCI, the terminal device schedules the physical layer to determine to discard null packets sent on the one or more subframes. If one or more subframes bear the UCI, the terminal equipment schedules a physical layer to determine to send the null packets and the UCI on the one or more subframes.

Further, the terminal device may also transmit the TPC packet in the PUSCH. Wherein, the TPC is used for adjusting the uplink transmission power. When the network performance between the terminal device and the network device is good, the terminal device does not need to adjust the uplink transmission power, and when the network performance between the terminal device and the network device is poor, the terminal device needs to adjust the uplink transmission power based on the TPC. Optionally, the network performance between the terminal device and the network device may be measured by a network performance index. For example, the network performance indicator may be an uplink block Error Rate (UL BLER). When the UL BLER is less than or equal to the preset threshold (i.e., the network performance indicator satisfies the preset condition), the terminal device may determine that the network performance between the terminal device and the network device is good, and the terminal device does not need to adjust the uplink transmission power.

When it is determined that the discarded null packet includes the TPC, if the terminal device discards the null packet and also discards the TPC in the null packet, the terminal device may not adjust the uplink transmission power according to the TPC, and may affect subsequent data transmission. Based on this, in one embodiment, when there are N subframes of the PUSCH, all of which do not carry SDUs, the terminal device may schedule the physical layer to determine one or more subframes, other than the N subframes, in the PUSCH, which do not carry SDUs; if one or more subframes carry TPC and the TPC indicates to adjust the uplink transmission power of the terminal equipment, the terminal equipment schedules a physical layer to obtain a network performance index; and when the network performance index meets the preset condition, the terminal equipment schedules the physical layer to discard the TPC. And when the network performance index does not meet the preset condition, the terminal equipment schedules a physical layer to store the TPC, so that the uplink transmission power is adjusted based on the stored TPC in the subsequent data transmission process.

In this embodiment of the application, the terminal device may obtain a PUSCH transmitted by the terminal device, and when the number of subframes not carrying SDU in the PUSCH is greater than or equal to N, discard an empty packet transmitted on a subframe not carrying SDU except N subframes in the PUSCH. And a large number of empty packets which do not bear SDU can be prevented from being sent in the PUSCH, and the power consumption of the terminal equipment is saved. In addition, the terminal device may schedule the physical layer to acquire one or more subframes on the subframe which does not carry the SDU except for the N subframes in the PUSCH, and determine whether to discard the null packet in the one or more subframes according to whether the one or more subframes carry the UCI and/or determine whether to discard the TPC in the one or more subframes according to whether the one or more subframes carry the TPC, so that effective information in the PUSCH may be prevented from being discarded, network performance is guaranteed while power consumption of the terminal device is saved, and user experience is improved.

As can be seen from the above description of the method embodiment shown in fig. 2, in the data processing method shown in fig. 2, when the number of subframes not carrying SDUs in the PUSCH is greater than or equal to N, the terminal device may determine to discard null packets sent on subframes not carrying SDUs except N subframes in the PUSCH. In a specific implementation process, the data processing method shown in fig. 2 may be completed by means of the identification information. Referring to fig. 3, the data processing method may include S301 to S304:

s301: and acquiring the PUSCH sent by the terminal equipment.

It should be noted that, the specific implementation process of S301 may refer to the specific description of the related embodiment in fig. 2, and is not described herein again.

S302: and when the first type subframe exists in the PUSCH, the terminal equipment schedules the MAC layer to generate first identification information.

It should be noted that the identification information related to the embodiment of the present application is used to indicate the state of the terminal device. In the embodiment of the present application, the identification information usually appears in groups, and one group includes two opposite identification information, that is, two types of identification information are mutually exclusive and are respectively used for indicating two states of the terminal device. For example, embodiments of the present application relate to first identification information and third identification information, where the first identification information is used to indicate that a first type subframe exists in a PUSCH, and the third identification information is used to indicate that the first type subframe does not exist in the PUSCH. For another example, the embodiments of the present application also relate to second identification information and fourth identification information. The second identification information is used for indicating that the number of the first type subframes in the PUSCH is greater than or equal to N. The fourth identification information is used for indicating that the number of the first type subframes existing in the PUSCH is less than N. And so on.

Optionally, in this embodiment of the present application, the identification information may be any information with a distinguishing capability. For example, the identification information may be a field and/or bits.

For the first identification information and the third identification information, in an embodiment, the first identification information and the third identification information may be fields, the first identification information may be a first field, and correspondingly, the third identification information may be a third field. The first field is used for indicating that the first type subframe exists in the PUSCH, and the second field is used for indicating that the first type subframe does not exist in the PUSCH. Wherein, the first field and the third field mentioned above refer to different fields, for example, the first field is "true", and the third field is "false"; or the first field is "false", the third field is "true", and so on, which is not limited in this embodiment of the application.

In another embodiment, the first identification information and the third identification information may be bits, the first identification information may be a first bit value, and correspondingly, the third identification information may be a third bit value. The first bit value is used for indicating that the first type subframe exists in the PUSCH, and the third bit value is used for indicating that the first type subframe does not exist in the PUSCH. Wherein, the first bit value and the third bit value mentioned above refer to different bit values, for example, the first bit value is "1", and the third bit value is "0"; or, the first bit value is "0", the third bit value is "1", and so on, which is not limited in this embodiment of the application.

S303: and the terminal equipment scheduling MAC layer acquires the number of the first type subframes in the PUSCH, and when the number of the first type subframes is more than or equal to N, the terminal equipment scheduling MAC layer generates second identification information.

Similarly to the first identification information and the third identification information, for the second identification information and the fourth identification information, in an embodiment, the second identification information and the fourth identification information may be fields, the first identification information may be a second field, and correspondingly, the fourth identification information may be a fourth field. The second field is used for indicating that the number of the first type subframes existing in the PUSCH is larger than or equal to N, and the fourth field is used for indicating that the number of the first type subframes existing in the PUSCH is smaller than N. Wherein, the above-mentioned second field and fourth field refer to different fields, for example, the second field is "true", and the fourth field is "false"; or the second field is "false", the fourth field is "true", and so on, which is not limited in this embodiment of the application.

In another embodiment, the second identification information and the fourth identification information may be bits, the second identification information may be a second bit value, and correspondingly, the fourth identification information may be a fourth bit value. The second bit value is used for indicating that the number of the first type subframes existing in the PUSCH is larger than or equal to N, and the fourth bit value is used for indicating that the number of the first type subframes existing in the PUSCH is smaller than N. Wherein, the above-mentioned second bit value and the fourth bit value refer to different bit values, for example, the second bit value is "1", and the fourth bit value is "0"; or, the second bit value is "0", the fourth bit value is "1", and so on, which is not limited in this embodiment of the application.

S304: and when the terminal equipment schedules the MAC layer to generate the second identification information, the terminal equipment schedules the physical layer to determine to discard the empty packet sent on the subframe which does not bear the SDU in the PUSCH.

For a better description of the present solution, a detailed description is given with reference to examples. As shown in fig. 4 a-4 e, a diagram of a subframe in a time domain resource is shown. Three types of subframes may be included in the time domain resources: a first type subframe, a second type subframe, and a third type subframe. In fig. 4 a-4 e, a subframe may be represented by a rectangle. The first type subframe is represented by a rectangle carrying a text 'PUSCH null packet', the second type subframe is represented by a rectangle carrying a text 'PUSCH SDU', the third type subframe is represented by a rectangle carrying a text 'no PUSCH', and the first type subframe carrying UCI is represented by a rectangle carrying a text 'PUSCH null packet + UCI'. Subframes normally transmitted in PUSCH may be represented in white, subframes where null packets are dropped in PUSCH may be represented in gray, and subframes of the third type may be represented in black.

In one embodiment, the terminal device may schedule the MAC layer to generate the initialization information, that is, the terminal device may schedule the MAC layer to generate the third identification information and the fourth identification information, and set the number of the first type subframes to zero. Wherein the third identification information may be represented as starWinFlag = false, the fourth identification information may be represented as zeroSDUFlag = false, and the number of the first type subframes may be represented as PUSCH _cnt The number of the first type subframe is set to zero, which can be expressed as PUSCH _cnt ＝0。

In one embodiment, the terminal device may have either a third type subframe or a second type subframe before determining that the first type subframe is present in the PUSCH.

As shown in the upper diagram of fig. 4a, the terminal device may have a subframe of the third type before determining that the subframe of the first type exists in the PUSCH, at t ₁ At this time, the terminal device determines that the first type subframe exists in the PUSCH, and the terminal device may schedule the MAC layer to generate the first identification information, which may be denoted as startwinflag = true.

As shown in the lower diagram of FIG. 4a, the terminal device may have a second type of subframe before determining that there is a first type of subframe in PUSCH, at t ₁ At this time, the terminal device determines that the first type subframe exists in the PUSCH, and the terminal device may schedule the MAC layer to generate the first identification information, which may be denoted as starWinFlag = true.

In one embodiment, when the terminal device generates the first identification information (startwinflag = true), the terminal device may schedule the MAC layer to acquire the number of the first type of subframes present in the PUSCH. As shown in fig. 4b, at t ₁ In time statistics PUSCHThe number of first type subframes present, the number of first type subframes being 1, may be denoted as PUSCH _cnt =1. At this time, the terminal device may schedule the MAC layer to determine whether the number of the first type subframes is greater than or equal to N, and when the number of the first type subframes is greater than or equal to N, the terminal device schedules the MAC layer to generate the second identification information (zeroSDUFlag = true).

Let N =1 at t ₁ At the moment, the number of first type subframes is equal to N (i.e. PUSCH) _cnt = N), the terminal device may schedule the MAC layer to generate the second identification information (zeroSDUFlag = true), and the terminal device may schedule the physical layer to determine to discard the null packet sent on the subframe not carrying the SDU in the PUSCH, that is, as shown in the upper diagram of fig. 4b, the terminal device determines to discard the null packet sent on the subframe 401.

Let N =3 at t ₁ At the moment, the number of the first type subframes is less than N (i.e. PUSCH) _cnt <N), the terminal device does not schedule the MAC layer to generate the second identification information, and at this time, the terminal device keeps the fourth identification information (zeroSDUFlag = false), and the terminal device schedules the physical layer to normally send the empty packet of the subframe 402, as shown in the lower diagram of fig. 4 b.

For the case that the number of the first type subframes is greater than or equal to N, the terminal device generates the second identification information (zeroSDUFlag = true): optionally, the next subframe may still be the first-type subframe, the number of the first-type subframes is still greater than or equal to N, and the terminal device may schedule the physical layer to determine to discard the null packet sent on the subframe which does not carry the SDU in the PUSCH. Taking the example of N =1 as an example, as shown in the upper diagram of fig. 4c, the subframe 403 is a first type subframe, and the number of first type subframes existing in the PUSCH is 2 (PUSCH) _cnt = 2), the number of first type subframes is greater than N (PUSCH) _cnt >N), the terminal device may schedule the physical layer to determine to discard the null packet transmitted on subframe 403.

For the case that the number of the first type subframes is less than N, the terminal device does not generate the second identification information, and the terminal device holds the fourth identification information (zeroSDUFlag = false): optionally, the next subframe may be a first type subframe, the terminal device may obtain the number of the first type subframes, schedule the MAC layer again to determine whether the number of the first type subframes is greater than or equal to N, and when the number of the first type subframes is greater than or equal to N, the terminal device schedules the MAC layer to generate the second identification information (zeroSDUFlag = true).

Optionally, the next subframe may be a subframe of the third type. At this time, the number of the first type subframes is not changed.

It should be noted that, for a specific implementation manner in which the number of the first-type subframes is less than N, reference may be made to the related embodiment in which the number of the first-type subframes is greater than or equal to N. And, the specific implementation manner of the subsequent subframe may also refer to the specific description of the above embodiments, which is not repeated here

To facilitate obtaining the sum of the number of the first type subframes and the third type subframes in the time window, the sum of the number of the first type subframes and the third type subframes in the time window may be denoted as W _cnt . When the terminal device schedules the MAC layer to generate the initialization information, the sum of the number of the first type subframes and the third type subframes needs to be set to zero, namely W _cnt ＝0。

As shown in fig. 4d, at t ₁ At the moment, the terminal equipment determines that the first type subframe exists in the PUSCH, the terminal equipment can schedule the MAC layer to open a time window, and the sum, W, of the number of the first type subframe and the number of the third type subframe in the time window is obtained _cnt ＝1。

Optionally, when the sum of the number of the first-type subframes and the third-type subframes is greater than or equal to the subframe number threshold of the time window, the terminal device schedules the MAC layer to generate the initialization information, that is, generate the third identification information and generate the fourth identification information, and set the number of the first-type subframes to zero. And setting the sum of the number of the first type subframes and the third type subframes to zero. The threshold of the number of subframes of the time window may be set according to experience or traffic requirements. As shown in the upper diagram of FIG. 4d, assuming that the threshold value of the number of subframes of the time window is 3, at t ₂ The sum of the number of the first type sub-frames and the number of the third type sub-frames within the time window, W _cnt And =3, generating third identification information and fourth identification information by the number of the first type subframes and the third type subframes and a threshold value equal to the number of the subframes of the time window, and setting the number of the first type subframes to zero. Optionally, the sum of the number of the first type subframes and the third type subframes may also be set to zero. Namely, starWinflag = false, zeroSDUFlag = false, PUSCH _cnt ＝0，W _cnt ＝0。

Optionally, in the time window, when there is a second type subframe in the PUSCH, the time window is closed, the terminal device schedules the MAC layer to generate the initialization information, that is, generate the third identification information and generate the fourth identification information, and set the number of the first type subframes to zero. And setting the sum of the number of the first type subframes and the third type subframes to zero. As shown in the lower diagram of fig. 4dShown at t ₃ At the moment, the second type subframe exists in the PUSCH, the terminal equipment generates initialization information, generates third identification information and fourth identification information, and sets the number of the first type subframe to zero. Optionally, the sum of the number of the first type subframes and the third type subframes may also be set to zero. Namely, starWinFlag = false, zeroSDUFlag = false, PUSCH _cnt ＝0，W _cnt ＝0。

Further, the terminal device may schedule the physical layer to determine whether to discard the null packet in the current subframe according to the second identification information. And if the current subframe does not bear the UCI, the terminal equipment schedules a physical layer to determine to discard the empty packet sent on the current subframe. And if the current subframe bears the UCI, the terminal equipment schedules a physical layer to determine to send the empty packet and the UCI on the current subframe.

The example of fig. 4c is followed. For the next subframe of the subframe 401, the next subframe may still be the first type subframe, the number of the first type subframes is still greater than or equal to N, and the terminal device may schedule the physical layer to determine one subframe of the subframe which does not carry the SDU in the PUSCH. And if the subframe does not bear the UCI, the terminal equipment schedules a physical layer to determine to discard the null packet sent on the subframe. As shown in the upper diagram of fig. 4e, the next subframe is a subframe 403, and the subframe 403 does not carry UCI, then the terminal device schedules the physical layer to determine to discard the null packet in the subframe 403. If the subframe carries the UCI, the terminal equipment schedules a physical layer to determine to send the null packet and the UCI on the subframe. As shown in the lower diagram of fig. 4e, the next subframe is a subframe 406, and the subframe 406 carries UCI, then the terminal device schedules the physical layer to transmit null packets and UCI in the subframe 406.

Further, the terminal device may perform the data processing method as shown in fig. 5 for each subframe.
