摘要: Techniques are provided for radio frequency (RF) sensing using a single wireless device. An example method for determining a distance to an object with radio frequency sensing includes transmitting a radio frequency signal with a transmit channel on a wireless device, receiving a leakage signal with a receive channel on the wireless device at a first time, such that the leakage signal is based on the radio frequency signal, receiving a reflected signal with the receive channel on the wireless device at a second time, such that the reflected signal is based on the radio frequency signal reflecting from the object, and determining the distance to the object based at least in part on a difference between the first time and the second time.

摘要: Repetitions of a control signal across a plurality of first subframes and a data signal allocated to a resource indicated by the control signal are received. Repetition of a response signal for the data signal across a plurality of second subframes is performed, and a transmission signal is generated by multiplying the response signals in the second subframes by, among a plurality of first sequences orthogonal to one another, components of one of the first sequences which is associated with the first subframes, respectively.

摘要: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention relates to a method and an apparatus for estimating an uplink channel of a base station in a wireless communication system, comprising the steps of: estimating a position of a wireless channel tap on the basis of a sounding reference signal (SRS) received from a terminal; determining an average power value of the wireless channel tap for each link between a transmitting antenna and a receiving antenna from and to which the SRS is transmitted; and estimating an effective channel frequency response (effective CFR) of a physical uplink shared channel (PUSCH) on the basis of the position of the wireless channel tap and the average power value of the wireless channel tap.

摘要: New sequences have been proposed and/or adopted for short Physical Uplink Control Channel communications between base stations and UEs. In an exemplary embodiment, a UE communicates with a base station based on sequence groups that include the new sequences, where the new sequences are allocated to different sequence groups based, at least in part, on correlations with other existing sequences included in individual sequence groups.

摘要: A terminal according to one aspect of the present disclosure includes: a receiving section that receives a signal over a plurality of resources; and a control section that multiplies the signal thus received, by a value in an orthogonal cover code (OCC) for each resource in the plurality of resources, and measures a channel state information (CSI)—reference signal (RS) obtained by adding results of the multiplication. The resource is a period longer than a resource block or a symbol. According to one aspect of the present disclosure, a CSI-RS transmitted by using a larger number of CSI-RS ports can be appropriately measured.

摘要: A terminal according to one aspect of the present disclosure includes: a control section that assumes that a frequency domain orthogonal cover code (FD-OCC) having a sequence length of a number larger than two is applied to a demodulation reference signal mapped to a pair of resource elements the number of which is greater than two and that are being different in frequency; and a transmitting/receiving section that performs transmission processing or reception processing of the demodulation reference signal, based on the FD-OCC. According to one aspect of the present disclosure, even when there are terminals according to different releases, each of the terminals can appropriately perform communication.

摘要: A terminal apparatus includes circuitry and a transmitter. The circuitry, in operation, generates a reference signal using a cyclic shift value and an orthogonal sequence, which are associated with each other. The orthogonal sequence is one of two orthogonal sequences corresponding to a first orthogonal sequence [1, 1] and a second orthogonal sequence [1, −1]. The cyclic shift value is one of 12 cyclic shift values ranging from 0 to 11. The transmitter, in operation, transmits the reference signal multiplexed with a data signal. Two of the cyclic shift values having a difference of 6 are respectively associated with the two orthogonal sequences.
