Abstract

The application discloses methods and apparatuses in user equipment and a base station for wireless communication. The user equipment receives a first signaling and then receives a second signaling, and then operates a first wireless signal and a second wireless signal respectively in first time-frequency resources; the first wireless signal and the second wireless signal occupy a first resource unit set and a second resource unit set respectively; and the first signaling is used for determining whether the second signaling includes a first domain and the first domain is used for determining that a target resource element set belongs to the first resource unit set or the second resource unit set. According to the application, the first domain and the target resource unit establish connection, so that a phenomenon that blind decoding costs are caused by introduction of the extra control signaling because the user equipment obtains configuration of an auxiliary demodulation reference signal when the system carries out the auxiliary demodulation reference signal configuration is avoided. Therefore, the complexity of the user equipment is reduced and the overall performance of the system is improved.

Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, especially a wireless signal transmission method and device supporting high-speed mobile communication. Background technique [0002] Massive MIMO (Multi-Input Multi-Output) has become a research hotspot in the next generation of mobile communications. In massive MIMO, multiple antennas use beamforming to form narrower beams pointing in a specific direction to improve communication quality. For massive MIMO and future 5G communications, high-speed mobility will be a scenario that needs to be discussed. [0003] In the 3GPP (3rd Generation Partner Project, third-generation partnership project) NR discussion, the consensus of most companies is that for high-speed mobile or other scenarios where wireless channel conditions deteriorate, especially when massive MIMO is introduced , the density of the existing DMRS will not be able to guarantee the transm...
