-the name of the invention of the original application: user equipment, method and device in base station for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a method and apparatus for unlicensed uplink transmission.

Background

In conventional 3GPP (3 rd Generation Partner Project, third generation partnership project) LTE (Long-term Evolution) and 5G NR systems, power control is required for uplink transmission at the terminal side to ensure that the base station can efficiently receive the transmission data at the terminal side. For different channels, the terminal side adopts different power control strategies, such as Preamble sequences (preambles) and PUSCH (Physical Uplink Shared Channel), and the terminal can respectively and independently perform power control and power selection. At the same time, the maximum transmission power of the terminal is limited to ensure the endurance time and battery life of the terminal.

In the future 5g NR Phase 2 and the following evolution, one base station will support an application scenario with a number greatly increased compared with the number of terminals in the existing system. When the number of terminals is large, the grant-free uplink transmission will more show the advantages of small overhead of air interface signaling and high spectrum efficiency, and the power control scheme for the grant-free uplink transmission needs to be redesigned.

Disclosure of Invention

In the conventional LTE system and the 5G NR system, when the Preamble and the PUSCH are transmitted, the user equipment respectively follows an independent power control process, and the transmission power cannot be greater than the maximum uplink transmission power so as to ensure the battery life of the user equipment. In grant-free uplink transmission, a common way is that the ue sends the Preamble and uplink data in different air interface resource sets, and the base station can obtain the identification information of the ue through the Preamble, and also can use the Preamble to help the uplink data to perform channel estimation and demodulation, so as to improve transmission performance. However, the above manner requires that the base station side correctly presumes the transmission power of the Preamble and the uplink data, so as to ensure that the Preamble and the uplink data are correctly received, and the existing system cannot correctly predict the relationship between the transmission power of the Preamble and the uplink data because the power control of the Preamble and the uplink data is an independent process. In view of the above problems, a simple solution is to let the ue transmit the grant-free Preamble and uplink data with the same transmit power; however, this method is not efficient and flexible enough, and may affect the reception performance of the Preamble.

In view of the above, the present application discloses a solution.

Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane and a control plane, fig. 3 shows the radio protocol architecture for a User Equipment (UE) and a base station device (gNB or eNB) in three layers: layer 1, layer 2 and layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY301. In the user plane, the L2 layer 305 includes a MAC (Medium Access Control ) sublayer 302, an RLC (Radio Link Control, radio link layer control protocol) sublayer 303, and a PDCP (Packet Data Convergence Protocol ) sublayer 304, which terminate at the gNB on the network side. Although not shown, the UE may have several upper layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., remote UE, server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, security by ciphering the data packets, and handover support for UEs between gnbs. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat reQuest ). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating the various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and the gNB is substantially the same for the physical layer 301 and the L2 layer 305, but there is no header compression function for the control plane. The control plane also includes an RRC (Radio Resource Control ) sublayer 306 in layer 3 (L3 layer). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the gNB and the UE.
