Detailed ways

In order to have a more detailed understanding of the characteristics and technical content of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present application.

Before describing in detail the uplink transmission method provided in the embodiments of the present application, a brief description of the cell handover process in the related technology will be given first.

At present, with people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the 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: Enhance Mobile Broadband (eMBB), Ultra Reliable Low Latency Communications (URLLC), and Massive Machine Type Communication (mMTC).

eMBB still aims for users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized, and must be analyzed in detail in conjunction with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc. Typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules and long service life.

Generally, the uplink data transmission and downlink data transmission of the terminal equipment in the connected state are dynamically scheduled by the network equipment. In order to better serve the periodic business, the 5G system introduces the concept of pre-configured resources, which can be half Continuous scheduling (Semi-Persistent Scheduling, SPS) downlink resources and configuration grant (Configured Grant, CG) uplink resources. There are two ways to configure Configured Grant resources, one is through radio resource control (Radio Resource Control, RRC) signaling configuration, and the other is through physical downlink control channel (Physical Downlink Control Channel, PDCCH) provision. Configured Grant resources are mainly configured in a periodic manner, and the corresponding configuration information may include frequency modulation mode, modulation and coding level, and resource allocation.

The maximum number of hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) processes of the terminal device is 16. For each CG configuration, the network device is configured with a limited number of HARQ process numbers, and after the media access control protocol data unit (MAC PDU1) is packaged at t0, the MAC PDU1 is stored in HARQ In process A; after t1, because the HARQ process is the same, even if MAC PDU1 has not been transmitted correctly at this time, MAC PDU1 will be flushed. Therefore, the mechanism of configured Grant Timer of the per HARQ process is introduced. Before the configured Grant Timer expires, the MAC PDU stored in the HARQ process cannot be flushed. In addition, according to the existing protocol, the configured Grant Timer will be turned on or restarted only when the transmission of this HARQ process is executed.

During the operation of the configured Grant Timer, the terminal device will also monitor the PDCCH scheduling scrambled by the Cell-RadioNetworkTemporaryIdentifier (C-RNTI) and the Configured Scheduling-RadioNetworkTemporaryIdentifier (CS-RNTI) plus Disturbed PDCCH scheduling. If the network device uses the PDCCH to schedule retransmission, the terminal device uses dynamically scheduled uplink grant resources or dynamically scheduled configured grant resources for retransmission. If the configured Grant Timer expires, the terminal device confirms that the previously transmitted MAC PDU is correctly received by the network device.

The following briefly describes the uplink transmission skipping (UpLink skipping, UL skipping). UL skipping can also be referred to as upstream skipping or not performing upstream transmission. The pre-configured configured grant may not completely match the time when the terminal device generates the data packet, so the terminal device needs to send the padding data packet on the UL grant. Since the padding data packet does not carry any useful data, the terminal device sending the padding data packet will increase the power consumption of the terminal device and cause unnecessary uplink interference. The concept of UL skipping is introduced in the 5G system. The network device will configure whether to enable the UL skipping function for a specific MAC entity; specifically, the network equipment section configures whether to enable the UL skipping function through the skipUplinkTxDynamic field.

The MAC entity of the terminal device will not generate MAC PDUs for the HARQ entity in the following situations:

1) If the MAC entity has been configured with skipUplinkTxDynamic and the value of skipUplinkTxDynamic 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 Address to CS-RNTI); and,

2) There is no aperiodic channel state information (Channel State Information, CSI) requested for this transmission time interval (Transmission Time Interval, TTI); and,

3) MAC PDU contains zero MAC Service Data Unit (SDU); and,

4) MAC PDU only includes padding buffer status report (Buffer Status Report, BSR) or periodic BSR, and no logical channel group (Logical Channel Group, LCG) has available data.

UL Skipping is similar to Discontinuous Transmission (DTX). By enabling the terminal device to skip the operation of sending data when there is no message data to send, it can save the transmission power of the terminal device; by reducing possible wireless transmission interference , Can improve the effectiveness of the system.

In related technologies, after the dynamic grant/configured grant resource is transmitted, during the running of the configured Grant Timer, the terminal device will also monitor the C-RNTI/CS-RNTI scrambled PDCCH scheduling. If the network device schedules the terminal device to perform uplink retransmission through the PDCCH , The terminal equipment uses dynamic UL grant resources of dynamic scheduling (C-RNTI/CS-RNTI addressing) for uplink retransmission. Even if the terminal device performs UL skipping on the dynamic grant/configured grant because there is no data to transmit, there are cases where the network device cannot detect DTX, so it is impossible to confirm whether the terminal device has skipped the first uplink transmission. The network device may continuously schedule the terminal device to perform uplink retransmission. According to the existing agreement, the terminal device will ignore the UL grant for the uplink retransmission scheduled by the PDCCH scrambled by the CS-RNTI; for the first transmission, the resource is dynamically scheduled (dynamic grant) and the terminal device has no data to transmit. UL skipping is performed on this resource. For subsequent uplink retransmissions scheduled by the C-RNTI scrambled PDCCH, the terminal device will continue to perform UL skipping, which causes a waste of resources.
