The disclosure relates to transmission methods and devices in wireless communication systems, and in particular to a transmission method and device for radio signals supporting data transmission based on Semi-Persistent Scheduling (SPS).
At present, technical discussions about 5G New Radio Access Technology (NR) are ongoing. Massive Multi-Input Multi-Output (MIMO) becomes a research hotspot of next-generation mobile communications. In the massive MIMO, multiple antennas experience beamforming to form a relatively narrow beam which points to a particular direction to improve the quality of communication. When a number of panels equipped at a User Equipment (UE) is limited, a number of beamforming vectors of the UE used for simultaneous reception is limited too. Meanwhile, 5G systems will still support data transmission based on SPS, so as to implement services with data amount and transmission periodicity fixed using a few dynamic scheduling signalings.
Therefore, when a UE supports SPS and massive MIMO simultaneously, a new scheme needs to be proposed.
Data scheduling based on SPS allows one time of scheduling to serve multiple time units, thereby reducing overheads and loss of dynamic signalings. However, for UEs supporting massive MIMO, when one UE performs data transmission based on SPS in multiple time units, the UE needs to receive using a same receiving beamforming vector or to transmit using a same antenna port. Since a base station needs to provide services to other UEs in timeslots occupied by the SPS transmission, the SPS transmission will result in that only one transmission mode of beamforming can be employed in the time units occupied by the SPS, which will impact system performances. In view of the above problem, one simple solution is that the SPS employs a wider beam to perform transmission; however, this solution will reduce the efficiency of transmission obviously.
In view of the design, the disclosure provides a solution. It should be noted that the embodiments of the UE of the disclosure and the characteristics in the embodiments may be applied to the base station if no conflict is incurred, and vice versa.
