Patent number: 11723031Abstract: The present invention relates to a D2D capable a communication method and to a transmitting user equipment, which transmits data to a receiving user equipment over a direct link data channel, uses the services of the eNodeB in order to have resources allocated for transmitting said data. To this end the UE sends to the eNB scheduling information using resources of a subframe dedicated for standard uplink communication through the eNodeB, rather than using resources on the subframe dedicated to D2D data transmission. In order to allow the eNB to distinguish whether the received scheduling request is for allocating resources for transmitting data over the direct link channel or over the eNB, UE may send along with the scheduling information also identification information associated to the scheduling information.Type: GrantFiled: March 24, 2021Date of Patent: August 8, 2023Assignee: Sun Patent TrustInventors: Joachim Loehr, Prateek Basu Mallick

Patent number: 11700098Abstract: Disclosed are a wireless transmitter and a reference signal transmission method that improve channel estimation accuracy. In a terminal, which transmits a reference signal using n (n is a non-negative integer 2 or greater) band blocks (which correspond to clusters here), which are disposed with spaces therebetween in a frequency direction, a reference signal controller switches the reference signal formation method of a reference signal generator between a first formation method and a second formation method based on the number (n) of band blocks. In addition, a threshold value setting unit adjusts a switching threshold value based on the frequency spacing between band blocks. Thus, the reference signal formation method can be selected with good accuracy and, as a result, channel estimation accuracy is further improved.Type: GrantFiled: June 16, 2022Date of Patent: July 11, 2023Assignee: Sun Patent TrustInventors: Takashi Iwai, Sadaki Futagi, Tomohumi Takata, Daichi Imamura, Yoshihiko Ogawa
