Detailed Description

So that the manner in which the features and elements of the present embodiments can be understood in detail, a more particular description of the embodiments, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

Before describing the uplink transmission method provided in the embodiment of the present application in detail, a cell handover process in the related art is briefly described.

Currently, with the pursuit of speed, delay, high-speed mobility, energy efficiency, and diversity and complexity of services in future life, the 3GPP international standards organization has begun to develop 5G. The main application scenarios of 5G are: enhanced Mobile Ultra wide band (eMBB), Low Latency high reliability Communications (URLLC), and Massive Machine Type Communications (mMTC).

The eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the capabilities and the requirements is relatively large, it cannot be said in a general way, and it is necessary to analyze in detail in combination with a specific deployment scenario. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), traffic safety, etc. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

Generally, uplink data transmission and downlink data transmission of a terminal device in a connected state are dynamically scheduled by a network device, and in order to better serve periodic services, a concept of pre-Configured resources is introduced in a 5G system, which may specifically be Semi-persistent scheduling (SPS) downlink resources and Configuration Granted (CG) uplink resources. The Configured Grant Resource has two configuration modes, one is Configured through Radio Resource Control (RRC) signaling, and the other is provided through a Physical Downlink Control Channel (PDCCH). The Configured Grant resources are mainly Configured in a periodically occurring manner, and the corresponding configuration information may include a frequency modulation mode, a modulation coding level, resource allocation, and the like.

The number of the maximum Hybrid Automatic Repeat reQuest (HARQ) processes of the terminal device is 16. For each CG configuration, the network device configures a limited number of HARQ process numbers, and packs a Media Access Control Protocol Data Unit (MAC PDU1) at time t0, and then stores MAC PDU1 in HARQ process a; after time t1, since the HARQ process is the same, MAC PDU1 will be emptied (flush) even though MAC PDU1 has not been transmitted correctly at this time. Therefore, a mechanism of configured Grant Timer of per HARQ process is introduced. The MAC PDU saved in the HARQ process cannot be flushed until the configured Grant Timer times out. And, according to the existing protocol, when the promotion performs the transmission of the HARQ process, the configured Grant Timer is started or restarted.

During the operation of the Configured Grant Timer, the terminal device may also simultaneously monitor a PDCCH schedule scrambled by a Cell-Radio network temporary identifier (C-RNTI) and a PDCCH schedule scrambled by a Configured Scheduling-Radio network temporary identifier (CS-RNTI). And if the network equipment utilizes the PDCCH to schedule retransmission, the terminal equipment uses the dynamically scheduled uplink grant resource or the dynamically scheduled configured grant resource to perform retransmission. If the configured Grant Timer times out, the terminal device confirms that the previously transmitted MAC PDU is correctly received by the network device.

A brief explanation of UpLink skip (UL skip) is provided below. UL skiping may also be referred to as uplink skipping, or as not performing uplink transmission. The preconfigured Configured grant may not completely match the time when the terminal device generates the packet, so the terminal device needs to send a padding packet on the UL grant. Since the padding packet does not carry any useful data, sending the padding packet by the terminal device may increase the power consumption of the terminal device and generate unnecessary uplink interference. The concept of UL clipping is introduced into the 5G system, and the network equipment configures whether to start the UL clipping function for a specific MAC entity; specifically, the network device configures whether to enable the UL skiping function through a skipplinktxdac field.

The MAC entity of the terminal device will not generate a MAC PDU for the HARQ entity in the following cases:

1) if the MAC entity is configured with skipplinkTxDinamic, the value of skipplinkTxDinamic is set to true, and the UL grant indicated to the HARQ entity is addressed to the C-RNTI or the UL grant indicated to the HARQ entity is a configured UL grant (i.e., addressed to the CS-RNTI); and the number of the first and second electrodes,

2) there is no aperiodic Channel State Information (CSI) requested for this Transmission Time Interval (TTI); and the number of the first and second electrodes,

3) a MAC PDU contains zero MAC Service Data Units (SDUs); and the number of the first and second electrodes,

4) the MAC PDU contains only padding Status Report (BSR) or periodic BSR, and no data is available for any Logical Channel Group (LCG).

The UL blanking class is similar to Discontinuous Transmission (DTX), and can save the Transmission power of the terminal device by causing the terminal device to skip the operation of transmitting data when there is no message data to be transmitted; the effectiveness of the system can be improved by reducing possible radio transmission interference.

In the related art, after the transmission of the dynamic Grant/configured Grant resources, the terminal device may also monitor PDCCH scheduling scrambled by C-RNTI/CS-RNTI during the operation of the configured Grant Timer, and if the network device schedules the terminal device for uplink retransmission through the PDCCH, the terminal device uses dynamic UL Grant resources of dynamic scheduling (C-RNTI/CS-RNTI addressing) for uplink retransmission. Even if the terminal device performs UL skip on the dynamic/configured grant because there is no data to transmit, there is a case where the network device cannot detect DTX, and thus it is not possible to confirm whether the terminal device skip has been the first uplink transmission. The network device may continuously schedule the terminal device for uplink retransmission. According to the existing protocol, aiming at uplink retransmission scheduled by PDCCH scrambled by CS-RNTI, the terminal equipment can ignore the UL grant; for the initial transmission of a dynamically scheduled resource (dynamic grant), and the terminal device executes UL puncturing on the resource because no data needs to be transmitted, the terminal device may continue to perform UL puncturing for the uplink retransmission of the PDCCH scheduling scrambled by the C-RNTI, thereby causing resource waste.

As shown in fig. 2, an optional processing flow of the uplink transmission method provided in the embodiment of the present application includes the following steps:

step S201, under the condition that a terminal device jumps over the primary uplink transmission of a first process, if the terminal device receives a retransmission request aiming at the first process, the terminal device obtains a first MAC PDU; the first MAC PDU comprises first indication information, and the first indication information is used for indicating that the terminal equipment has skipped primary uplink transmission of the first process.

In some embodiments, the terminal device obtaining the first MAC PDU may be the terminal device generating the first MAC PDU.

In some embodiments, the first indication information is carried in a MAC CE; or, the first indication Information is carried in Uplink Control Information (UCI).

In some embodiments, the skipping of the initial uplink transmission of the first process may be skipping the initial uplink transmission of the first process on a configured granted resource; or skipping the initial uplink transmission of the first process on the dynamically scheduled uplink resource.

In the embodiment of the present application, if a terminal device skips an initial uplink transmission of a first process, and the terminal device receives a retransmission request on a dynamic UL grant resource for the first process, the terminal device does not ignore (ignore) the UL grant resource but generates a first MAC PDU; the first MAC PDU includes first indication information, where the first indication information is used to indicate that the terminal device has skipped the first uplink transmission of the first process. Therefore, under the condition that the network equipment receives the first indication information sent by the terminal equipment, the network equipment knows that the terminal equipment has skipped the initial uplink transmission of the first process, and then the network equipment judges that the uplink transmission of the first process is not required to be scheduled, so that the network resources are saved.

In some embodiments, the second configuration information may be carried in RRC signaling. The second configuration information and the first configuration information may be carried in the same signaling or may be carried in different signaling.

In specific implementation, if the network device configures a skipplinktxdac field for a specific MAC entity of the terminal device, and a value corresponding to the skipplinktxdac field is true, the terminal device starts an uplink transmission skip function.

The uplink transmission method provided in the embodiment of the present application is described in detail below with respect to different scenarios.

In a scenario where a resource for scheduling the initial uplink transmission of HARQ process 1 is a configured grant resource, and a network device sends a retransmission request for HARQ process 1 to a terminal device through a PDCCH scrambled by a CS-RNTI, a detailed processing procedure of the uplink transmission method provided in the embodiment of the present application includes:

step S301, the network device configures an uplink transmission skip function for the terminal device, and configures to send the first indication information when the terminal device performs retransmission.

In specific implementation, the network device may configure the terminal device with an uplink transmission skip function by configuring a skippelinktxdynamic field for the terminal device.

Step S302, the network device configures a skippenktxdynamic field for a specific MAC entity of the terminal device, and on a certain configured grant resource, the terminal device determines that there is no data and/or MAC CE to be sent, and then the terminal device skips uplink transmission of the current HARQ process 1.

Step S303, the network device schedules retransmission of the HARQ process 1 on dynamic UL grant resources through the PDCCH scrambled by the CS-RNTI.

In step S304, after the terminal device receives the dynamic UL grant resource scheduled by the PDCCH sent by the network device, as shown in fig. 3, the terminal device does not ignore the dynamic UL grant resource, but generates a MAC PDU. The MAC PDU includes first indication information; the first indication information is used to indicate that the terminal device skips uplink transmission of the HARQ process 1 on the previous configured grant resource.

Step S305, the terminal device transmits the generated MAC PDU to the network device.

In a scenario where a resource for scheduling the initial uplink transmission of HARQ process 1 is a dynamically scheduled UL grant resource, and a network device sends a retransmission request for HARQ process 1 to a terminal device through a PDCCH scrambled by a C-RNTI, a detailed processing flow of the uplink transmission method provided in an embodiment of the present application includes:

step S401, the network device configures an uplink transmission skip function for the terminal device, and configures to send the first indication information when the terminal device performs retransmission.

Step S402, the network device configures a skippenktxdymic field for a specific MAC entity of the terminal device, and on a certain dynamic UL grant resource, the terminal device determines that no data and/or MAC CE needs to be sent, and then the terminal device skips uplink transmission of the current HARQ process 1.

Step S403, the network device schedules retransmission of HARQ process 1 on dynamic UL grant resource through PDCCH scrambled by CS-RNTI.

In step S404, after receiving the dynamic UL grant resource scheduled by the PDCCH sent by the network device, as shown in fig. 4, the terminal device does not ignore the dynamic UL grant resource, but generates a MAC PDU. The MAC PDU includes first indication information; the first indication information is used to indicate that the terminal device skips uplink transmission of the HARQ process 1 on the previous configured grant resource.

Step S405, the terminal equipment sends the MAC PDU to the network equipment.

As shown in fig. 5, another optional processing flow of the uplink transmission method provided in the embodiment of the present application includes the following steps:

step S501, under the condition that a terminal device jumps over the primary uplink transmission of a first process, if the terminal device receives a retransmission request aiming at the first process, the terminal device obtains a second MAC PDU; the second MAC PDU includes data and/or a first MAC CE.

In some embodiments, the terminal device obtaining the second MAC PDU may be the terminal device obtaining the second MAC PDU from a Multiplexing and assembly entity (Multiplexing and assembly entity).

In some embodiments, the first process may be a HARQ process.

In the embodiment of the present application, if the terminal device determines that there is no data and/or MAC CE for the first uplink transmission of the first process, the terminal device does not perform the first uplink transmission of the first process. Then, if the terminal device receives a retransmission request on a dynamic UL grant resource for the first process, the terminal device does not ignore (ignore) the UL grant resource nor skip the UL grant, but obtains a second MAC PDU from a Multiplexing and allocation entity; if the first process has new data and/or new MAC CE, the terminal device may obtain a second MAC PDU from the Multiplexing and establishment entry, where the second MAC PDU includes the first performed new data and/or new MAC CE. In this way, under the condition that no retransmitted data and/or MAC CE exist, the terminal equipment transmits new data and/or new MAC CE by using the scheduled uplink resource for retransmission; thereby avoiding the waste of resources.

In some embodiments, the method further comprises:

step S500, the terminal device receives third configuration information sent by the network device, where the third configuration information includes whether the terminal device is allowed to send the second MAC PDU on the retransmission resource.

In some embodiments, the method further comprises:

step S500', the terminal device receives fourth configuration information sent by the network device, where the fourth configuration information includes whether the terminal device starts an uplink transmission skip function.

In some embodiments, the fourth configuration information may be carried in RRC signaling. The fourth configuration information and the third configuration information may be carried in the same signaling or may be carried in different signaling.

In some embodiments, if the terminal device obtains the second MAC PDU from the Multiplexing and establishment entity, the method further includes:

step S502, the terminal equipment sends a second MAC PDU to the network equipment.

In some embodiments, if the terminal device does not acquire the second MAC PDU from the Multiplexing and association entry, that is, the first process has no new data and/or new MAC CE, the method further includes:

in step S503, the terminal device generates a third MAC PDU.

In some embodiments, the terminal device itself generates a third MAC PDU, where the MAC PDU includes first indication information, and the first indication information is used to indicate that the terminal device has skipped the first uplink transmission of the first process.

Wherein, the first indication information may be carried in a second MAC CE; alternatively, the first indication information may also be carried in UCI.

In some embodiments, the terminal device may receive fifth configuration information sent by a network device, where the fifth configuration information includes whether the terminal device sends the first indication information when performing retransmission; in a case that the fifth configuration information includes the first indication information sent by the terminal device when performing retransmission, the terminal device may perform step S503.

The detailed processing flow of the uplink transmission method provided by the embodiment of the present application includes that a resource for scheduling the initial uplink transmission of the HARQ process 1 is a configured grant resource, and a network device sends a retransmission request scenario for the HARQ process 1 to a terminal device through a PDCCH scrambled by a CS-RNTI:

step S601, the network device configures an uplink transmission skip function for the terminal device, and configures to send the first indication information when the terminal device performs retransmission.

Step S602, the network device configures a skippenktxdynamic field for a specific MAC entity of the terminal device, and on a certain configured grant resource, the terminal device determines that no data and/or MAC CE needs to be sent, and then the terminal device skips uplink transmission of the current HARQ process 1.

Step S603, the network device schedules retransmission of HARQ process 1 on dynamic UL grant resources through PDCCH scrambled by CS-RNTI.

In step S604, after receiving the dynamic UL grant resource scheduled by the PDCCH sent by the network device, as shown in fig. 6, the terminal device performs an operation of acquiring the MAC PDU from the Multiplexing and allocation entity. If HARQ process 1 has new data and/or new MAC CE, the terminal device can obtain a new MAC PDU from the Multiplexing and association entry. At this time, the terminal device neither ignores the UL grant resource nor skip UL transmission, but transmits a new MAC PDU obtained from the Multiplexing and allocation entity by using the dynamic UL grant resource of the retransmission schedule, where the new MAC PDU includes new data and/or new MAC CE. And the terminal equipment sends the new MAC PDU obtained from the Multiplexing and association entry to the network equipment.

If HARQ process 1 has no new data and/or new MAC CE, the terminal device generates a MAC PDU by itself, wherein the MAC PDU comprises first indication information, and the first indication information is used for indicating that the terminal device skips the initial uplink transmission of the first process. And the terminal equipment transmits the generated MAC PDU to the network equipment.

step S801, the network device configures an uplink transmission skip function for the terminal device, and configures to send the first indication information when the terminal device performs retransmission.

Step S802, the network device configures a skippenktxdymic field for a specific MAC entity of the terminal device, and on a certain dynamic UL grant resource, the terminal device determines that no data and/or MAC CE needs to be sent, and then the terminal device skips uplink transmission of the current HARQ process 1.

Step S803, the network device schedules retransmission of HARQ process 1 on dynamic UL grant resource through PDCCH scrambled by CS-RNTI.

In step S804, after receiving the dynamic UL grant resource scheduled by the PDCCH sent by the network device, as shown in fig. 7, the terminal device performs an operation of acquiring the MAC PDU from the Multiplexing and allocation entity. If HARQ process 1 has new data and/or new MAC CE, the terminal device can obtain a new MAC PDU from the Multiplexing and association entry. At this time, the terminal device neither ignores the UL grant nor skip UL transmission, but transmits a new MAC PDU obtained from the Multiplexing and allocation entity by using dynamic UL grant resources of the retransmission schedule, where the new MAC PDU includes new data and/or new MAC CE. The terminal equipment sends the new MAC PDU obtained from the Multiplexing and establishment entry to the network equipment.
