[0002] -- Filing date of original application: March 26, 2017

[0003] --Original application number: 201710185617.9

[0004] --Title of the invention in the original application: A method and apparatus for user equipment and base station used for wireless communication Technical Field

[0005] The present application relates to a transmission method and device in a wireless communication system, and in particular to a transmission method and device in a wireless communication used for beamforming. Background Art

[0006] In the existing LTE (Long Term Evolution) system, the base station configures a variety of information related to physical layer transmission for UE (User Equipment) through RRC (Radio Resource Control) signaling, such as TM (Transmission Mode), DMRS (Demodulation Reference Signal) configuration, SRS (Sounding Reference Signal) configuration, resources occupied by PUCCH (Physical Uplink Control Channel), CSI-RS (Channel State Information-Reference Signal) configuration, etc. The above information is sent to the user equipment through UE-specific (UE-Specific) or cell-specific (Cell-Specific) signaling, and when the user equipment undergoes RRC reestablishment (Reestablishment), the above information will be reconfigured.

[0007] In future mobile communication systems, due to the introduction of beamforming and Massive-MIMO (Massive Multiple-Input Multiple-Output) systems, the above mechanism needs to be reconsidered. Summary of the invention

[0008] In future mobile communication systems, base stations will transmit downlink control channels and downlink data channels on multiple transmit beams (Tx-Beams). At the same time, UEs will also detect downlink control channels and downlink data channels on multiple receive beams (Rx-Beams). Due to the mobility, rotation and blocking of the transmission path of the UE, the UE may switch between multiple Tx-Beams or multiple Rx-Beams to obtain better reception quality, especially the reception quality of control signaling. For this scenario, there will be problems with the configuration of RRC signaling. One solution is to use RRC reconstruction. When the UE switches beams, the RRC signaling is reconfigured. An obvious disadvantage of this method is that it has a long delay and low efficiency, especially when the UE flexibly switches beams. This method is obviously not efficient enough. Another solution is that the UE uses the same set of RRC configurations no matter how it switches between beams. An obvious disadvantage of this method is that it is not flexible enough and will affect the performance gain brought by beamforming.

[0009] The present application provides a solution to the above problems. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other. For example, the embodiments of the user equipment of the present application and the features in the embodiments can be applied to the base station, and vice versa.

[0010] The present application discloses a method in a user equipment used for wireless communication, which comprises the following steps:

[0011] -Step A. receiving a first wireless signal in a first time period, wherein the first wireless signal includes a first signaling;

[0012] - Step B. Receive a second wireless signal in a second time period, wherein the second wireless signal includes second signaling.

[0013] The first signaling is non-terminal specific, and the second signaling is terminal specific. The first signaling and the second signaling include the same K fields, where K is a positive integer, and the K fields include at least one of {a field related to a transmission mode, a field related to multiple antennas, a field related to reserved air interface resources, and a field related to RS resources}.

[0014] As an embodiment, the characteristic of the above method is that: the first signaling is used for backup RRC information when the UE switches between multiple beams, and the second signaling is used for RRC information received by the UE under a given beam. When the UE triggers a beam switching (Beam Adaption) or triggers a beam recovery (Beam Recovery) process and it is not completed, the first signaling takes effect. When the UE works normally under a given beam, the second signaling takes effect.

[0015] As an embodiment, the advantage of the above method is that when the UE triggers beam switching or beam recovery (Recovery), the UE does not need to trigger the RRC reconfiguration process, and thus terminates the beam switching or beam recovery process below the RRC layer, thereby improving system efficiency and maximizing the gain brought by beamforming.
