Description

A method and device used in a base station and user equipment for wireless communication

technical field

The present application relates to a transmission method and device in a wireless communication system, in particular to a transmission method and device for multicast and multicast services using beamforming technology.

Background technique

In the M subframe, the broadcast multicast service cannot be multiplexed with other unicast services. Subsequently, in Release 13, a new MBMS service transmission mode, SC-PTM (Single Cell Point to Multipoint, single cell point to multipoint) transmission mode was introduced. Compared with the traditional MBMS transmission mode, SC-PTM has the biggest difference in that MBMS services are transmitted on PDSCH (Physical Downling Shared Channel, Physical Downlink Shared Channel) instead of PMCH (Physical Multicast Channel, Physical Multicast Channel). Services are not limited to transmission on M subframes.

In 5G NR (New Radio Access Technology, New Radio Access Technology) Phase 1 communication system, beamforming (Beamforming) is widely used, and in the subsequent evolution of NR Phase II, beamforming-based MBMS will also be discussed .

Contents of the invention

In the future 5G system, as the carrier frequency becomes higher, the transmission of wireless signals will have stronger directionality, and beamforming technology will be widely adopted. As for MBMS services, the strong directionality of wireless signals is obviously not conducive to the wide coverage requirements of MBMS services. Aiming at the above problems, one solution is to follow the current SC-PTM idea, that is, independently schedule UEs on PDSCH to achieve the effect of multicast and multicast, but obviously this will bring a large signaling overhead and lose PMCH The combination gain and the implementation are simple; another way is that the base station provides MBMS services in multiple beam directions. For the second method, when the RF (Radio Frequency, radio frequency) capability of the base station is limited, or there is interference between RFs, the above-mentioned multiple beams need to occupy multiple time resources, thereby causing the MBMS service to affect the transmission of the unicast service.

Based on the above problems and analysis, the present application discloses a solution.

Accompanying drawing 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane and a control plane, and Fig. 3 shows the radio protocol architecture for a user equipment (UE) and a base station device (gNB or eNB) with 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 PHY 301 and is responsible for the link between UE and gNB through PHY 301 . In the user plane, the L2 layer 305 includes MAC (Medium Access Control, Media Access Control) sublayer 302, RLC (Radio LinkControl, Radio Link Layer Control Protocol) sublayer 303 and PDCP (Packet Data Convergence Protocol, packet data convergence protocol) sublayers 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) terminating at the P-GW on the network side and a network layer (e.g., IP layer) terminating at the other end of the connection (e.g., application layer at the 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 packets to reduce radio transmission overhead, provides security by encrypting packets, and provides inter-gNB handover support for UEs. 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, 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 (eg, resource blocks) in one cell among UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for UE and gNB is substantially the same for the physical layer 301 and L2 layer 305, but there is no header compression function for the control plane. The control plane also includes an RRC (Radio Resource Control, radio resource control) sublayer 306 in layer 3 (L3 layer). The RRC sublayer 306 is responsible for obtaining radio resources (ie radio bearers) and configuring the lower layers using RRC signaling between the gNB and UE.
