Description

Method and device used in base station and user equipment for wireless communication
Technical Field
The present application relates to a transmission method and apparatus in a wireless communication system, and in particular, to a transmission method and apparatus for a multicast service under a beamforming technique.
Background
In a conventional 3GPP-3rd Generation partnership Project (3GPP-3rd Generation Partner Project) Long Term Evolution (LTE-Long Term Evolution) system, an MBSFN (Multicast Broadcast Single Frequency Network) subframe (M subframe for short) is defined, where the M subframe is mainly used for transmitting MBMS (Multimedia Multicast Service) services. 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) is introduced. Compared with the conventional MBMS transmission mode, the SC-PTM has the greatest difference that the MBMS service is transmitted on a PDSCH (Physical downlink shared Channel) instead of a PMCH (Physical Multicast Channel), and further the MBMS service is not limited to be transmitted on an M subframe.
Beamforming (Beamforming) is widely used in the 5G NR (New Radio Access Technology) Phase 1 communication system, and in the subsequent evolution of NR Phase II, MBMS based on Beamforming will be discussed.
Disclosure of Invention
In the future 5G system, as the carrier frequency becomes higher, the transmission of wireless signals will have stronger directivity, and further the beamforming technology will be adopted in a large amount. For the MBMS service, the strong directionality of the wireless signal is obviously not good for the requirement of the wide coverage of the MBMS service. Aiming at the problems, one solution idea is to use the existing concept of SC-PTM, namely, UE is independently scheduled on PDSCH to realize the effect of multicast, but obviously, the method brings larger signaling overhead, and loses the advantages of PMCH combination gain and simple realization; another way is for the base station to provide MBMS services in multiple beam directions. For the second method, when the RF (Radio Frequency) capability of the base station is limited or interference exists between the RFs, the multiple beams need to occupy multiple time resources, which further causes the MBMS service to affect the transmission of the unicast service.
Based on the above problems and analysis, the present application discloses a solution. Without conflict, embodiments and features in embodiments in the user equipment of the present application may be applied to the base station and vice versa. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.

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 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., 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.
