Description

Method and device used in user equipment and 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 uplink transmission in Non-Orthogonal Multiple Access (NOMA) technology.
Background
In a conventional 3GPP (3rd generation Partner Project) LTE (Long-term evolution) system, when a same time-frequency resource is scheduled to different users, the different users often use orthogonal code domain resources or different multiple access signatures to ensure that no interference occurs between them. In Release 13 and Release 14, based on the continuous improvement of device processing capability and the requirement of further improving spectral efficiency, NOMA technology is introduced into downlink data transmission to improve spectral efficiency.
Currently, a Technology discussion of 5G NR (New Radio Access Technology) is underway, wherein an important feature is support for multiple NOMA technologies in uplink transmission. Meanwhile, the unlicensed (Grant-Free) uplink transmission is researched in 5G by combining the NOMA technology due to the characteristics of small control signaling overhead, small time delay and the like.
Disclosure of Invention
In the NOMA technology, an important feature is that signals of two senders sharing the same block of time-frequency code resource need to have a certain power difference when reaching a receiver, so as to ensure that a signal with higher arrival power can be demodulated by the receiver first, and then the receiver adopts the SIC (Successive Interference Cancellation) technology to eliminate a stronger part of the signal, so as to ensure that a signal with lower arrival power can be received correctly. This is different from the idea that in conventional LTE systems and 5G systems it is desirable that all users reach the base station with the same power to achieve code division multiplexing. Aiming at the NOMA technology, a simple implementation is that a base station indicates different sending powers to paired users to ensure that the arrival power of the paired users can meet the power difference of SIC, however, the method is premised on that the base station needs the users to report the path loss of the base station to the users, obviously, the method introduces more signaling interaction, and is relatively inefficient in a Grant-Free uplink transmission mode.

Example 3
Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for the user plane and the control plane according to the present application, as shown in fig. 3.
Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for the User Equipment (UE) and the base station equipment (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 PHY 301. Layer 2(L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY 301. In the user plane, the L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) 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., far end 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 packets, retransmission of lost packets, and reordering of 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 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 without the header compression function for the control plane. The Control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3 (layer L3). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configures the lower layers using RRC signaling between the gNB and the UE.
As a sub-embodiment, the radio protocol architecture in fig. 3 is applicable to the user equipment in the present application.
