Description
Technical Field
The present invention relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus used for dynamic scheduling.
Background
Large scale (Massive) MIMO (Multiple Input Multiple Output) becomes a research hotspot of next generation mobile communication. In large-scale MIMO, multiple antennas form a narrow beam pointing to a specific direction by beamforming to improve communication quality. Both data channels and control channels can be used to improve transmission quality through multi-antenna beamforming.
In conventional LTE (Long Term Evolution) and LTE-a (Long Term Evolution Advanced, enhanced Long Term Evolution) systems, a physical layer Control channel corresponding to dci (downlink Control information) is transmitted in a non-beamforming manner. Hybrid beamforming, both analog beamforming and digital beamforming, has been discussed in 3GPP (3rd Generation partnership project) RAN1(Radio Access Network) and has been considered as an important research direction in NR (New Radio) systems. Since analog beamforming is a wideband operation, control channels using different analog beamforming vectors can only be transmitted in a TDM (Time domain multiplexing) manner, and accordingly new control channel designs need to be considered.
Disclosure of Invention
In the 5G system, one implementation is that the UE blindly detects the control signaling only in a time window corresponding to one beamforming vector, however, because the direction of the beamforming vector of the base station is inconsistent with the assumed direction of the UE and other unpredictable interference, blindly detecting only in a corresponding time window brings a risk of losing the control signaling. Another implementation manner is that the UE blindly detects the control signaling in the time windows corresponding to all beamforming vectors, which may cause the problems of higher complexity and more complex implementation.
The present invention provides a solution to the above problems. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict. For example, embodiments and features in embodiments in the UE of the present application may be applied in a base station and vice versa.
The invention discloses a method used in UE of dynamic scheduling, which comprises the following steps:
-step a. monitoring a first signalling in a first pool of time-frequency resources.
And the first time-frequency resource pool occupies N time windows in a time domain. The N time windows are in one-to-one correspondence with the N antenna port groups, and the antenna port groups comprise positive integer antenna ports. The N time windows are orthogonal in the time domain. The first signaling is physical layer signaling. In the first time-frequency resource pool, at most X detections are performed for the first signaling, where the X detections are for X RE sets respectively. For a given one of the X RE sets: if the number of included REs is greater than or equal to M1, the given RE set belongs to a first class RE set; or if the number of included REs is greater than or equal to M1, the given set of REs belongs to one of { a first set of REs, a second set of REs }; if the number of included REs is less than or equal to M2, the given RE set belongs to a second class of RE sets. The REs included in the first type of RE set are located in the N time windows. The REs included in the second type of RE set are all located in one time window. After rate matching, one bit in the bitstream corresponding to the first signaling can be mapped onto only one RE in the RE set. N is a positive integer greater than 1, and X is a positive integer greater than 1. The M1 is a positive integer greater than 1, the M2 is a positive integer less than the M1.
As an example, the above method has the benefits of: and transmitting the control signaling corresponding to the first type RE set in different N time windows by designing the first type RE set. Therefore, the control signaling is transmitted in the direction corresponding to the plurality of beamforming vectors to improve the robustness of transmission. While avoiding the problem of transmission of control signaling in the direction of one beamforming vector not being received correctly due to unforeseen interference.
As an example, another benefit of the above method is: the number of the RE occupied by the first type RE set is large, similar to a Candidate (Candidate) with a large AL (Aggregation Level) in a conventional system, and the RE set with the large AL only adopts a space diversity transmission mode, so that the blind detection times are reduced while the transmission performance of the first signaling is ensured.
As an example, a further benefit of the above method is that: the first type RE set is used for ensuring the transmission robustness of the first signaling. The second type RE set is used for ensuring the transmission efficiency of the first signaling. And by concentrating the second RE set into one time window for transmission, when the time window corresponds to an antenna port group with better UE channel conditions, transmitting the first signaling in the second RE set to realize channel gain and beamforming gain.
