摘要： A user equipment for wireless communications is provided. The user equipment comprises a transmitter (152) and a receiver (154). A first resource pool comprises a first plurality of resources for transmission. A second resource pool comprises a second plurality of resources for transmission. The second resource pool configuration is different from the first resource pool configuration or is equal to the first resource pool configuration. The transmitter (152) is configured to transmit a first critical communication notification being a first message in the first resource pool, wherein the first critical communication notification indicates that a second message is to be transmitted in the second resource pool. Moreover, the transmitter (152) is configured to transmit the second message in the second resource pool after transmitting the first critical communication notification or at a same time when transmitting the first critical communication notification. A third resource pool comprises a third plurality of resources for transmission. A fourth resource pool comprises a fourth plurality of resources for transmission. The fourth resource pool configuration is different from the third resource pool configuration or is equal to the third resource pool configuration. The receiver (154) is configured to receive a second critical communication notification being a third message, the second critical communication notification being transmitted in the third resource pool, wherein the second critical communication notification indicates that a fourth message is to be transmitted in the fourth resource pool. The transmitter (152) is configured to not transmit anything in the fourth resource pool in response to the receipt of the second critical communication notification by the receiver (154).

摘要： The invention concerns a method for receiving and a receiver configured to receive a radio signal (100) carrying information, the radio signal (100) comprising an overall frequency band (f overall ) having a first frequency sub band (101) and a second frequency sub band (102). According to the invention, the receiver is further configured to receive during a first time period (T 1 ) a first portion (111) of the information carried by the radio signal in the first frequency sub band (101), and to receive during a second time period (T 2 ) a second portion (112) of the information carried by the radio signal in the second frequency sub band (102). The receiver is further configured to perform a channel estimation (121) of the first frequency sub band (101) in orderto determine a first phase (131) and to perform a channel estimation (122) of the second frequency sub band (102) in order to determine a second phase (132). According to the invention, the receiver is further configured to determine an overall phase basis (133) of the radio signal using the first and second phases (131, 132).
