The present invention is designated to appropriately control intra-slot frequency hopping of an uplink channel/signal. A user terminal of the present invention includes a transmitting section that transmits an uplink data channel in one slot or over a plurality of slots, a receiving section that receives information related to frequency resource to which the uplink data channel is to be mapped, and a control section that controls frequency hopping of the uplink data channel in each slot, based on the information related to the frequency resource.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for narrowband communications using frequency hopping in an unlicensed frequency band. In some implementations, a base station (BS) may transmit downlink (DL) data using a sequence of DL hopping frames on a corresponding sequence of unique hopping channels associated with a DL frequency hopping pattern. In some implementations, each user equipment (UE) of one or more UEs may transmit uplink (UL) data using a sequence of UL hopping frames on a corresponding sequence of unique hopping channels associated with a different UL frequency hopping pattern.

A method for reference signal processing is provided. In this example, the method includes receiving, by a UE, a message from a network device, where the message indicates both that a first reference signal is to be transmitted over a first resource and that a second reference signal is to be transmitted over a second resource. The method also includes receiving, by the UE, at least the first reference signal in accordance with capabilities of the UE and the message received from the network device.

Methods, a terminal device and a base station for random access procedure are disclosed. According to an embodiment, the terminal device determines a frequency hopping configuration for transmission of one or more physical uplink shared channels (PUSCHs) in a request message for random access. The terminal device transmits the one or more PUSCHs in the request message based on the frequency hopping configuration. The request message at least comprises a physical random access channel (PRACH) preamble and the one or more PUSCHs.

A terminal according to one aspect of the present disclosure includes a control section that assumes that, in a case where time domain orthogonal cover code (TD-OCC) is configured for consecutive symbols of a sounding reference signal (SRS), the same sequence is configured to the consecutive symbols of the SRS, and a transmitting and/or receiving section that performs at least one of transmission processing and reception processing of the SRS, based on the TD-OCC. According to one aspect of the present disclosure, reduction in SRS capacity can be suppressed.

Infrastructure equipment forming part of a wireless communications network configured to receive data from a communications device via a communications channel between the infrastructure equipment and the communications device. The infrastructure equipment comprises circuitry configured to receive, from the communications device, a request for a resource allocation, to receive one or more reference symbols from the communications device, to estimate based on the received reference symbols, for each of a plurality of resource units, RUs, of the communications channel, a signal to interference and noise ratio, SINR, sequence of the communications channel, and to perform a first transform followed by a second transform on the SINR sequence to produce a cepstrum of the SINR sequence, the second transform being an inverse of the first transform, and to encode and to transmit the cepstrum to the communications device.

A user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.

The present disclosure relates to a method, a device, and a computer program for selecting a channel in a wireless communication system, and to a recording medium therefor. The method for selecting a channel by a first device in a wireless communication system, according to one embodiment of the present disclosure, may comprise the steps of: receiving a channel categorization report from a second device; and determining a channel map on the basis of at least one of the channel categorization report, a channel sensing result of the first device, and information provided by a host of the first device.

A wireless device may receive configuration parameters indicating a hopping pattern of bandwidth parts (BWPs) of a cell. The wireless device may start a BWP inactivity timer in response to activating a first BWP of the cell. In response to activating the hopping pattern, the wireless device may stop the BWP inactivity timer or it may deactivate the first BWP.

A method for transmitting an SRS by a user equipment may comprise the steps of: transmitting, to a base station, user equipment capability information including information on a frequency bandwidth where SRS frequency hopping for the user equipment is possible; receiving, from the base station, first information on an SRS bandwidth configuration and second information on the start point of an SRS frequency for transmission of an SRS; and transmitting the SRS to the base station on the basis of the first information and the second information, wherein the frequency bandwidth where SRS frequency hopping for the user equipment is possible corresponds to a partial frequency bandwidth within a bandwidth part (BWP) configured for transmission of the SRS. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.
