Certain aspects of the present disclosure provide techniques for indicating capability of a user equipment (UE) to support multiple sounding reference signals (SRSs) with a single subframe, with at least one of frequency hopping, different bandwidths, or antenna switching for the multiple SRSs in the same subframe.

The present disclosure relates to a communication technique that merges IoT technology with a 5G communication system for supporting higher data transmission rates than 4G systems, and a system therefor. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. The invention of the present disclosure proposes a method and device for transmitting and receiving a reference signal for efficiently using resources in a wireless communication system.

Embodiments of the present disclosure relate to methods, devices and computer storage media for communication. A method comprises transmitting, from a network device, Sounding Reference Signal (SRS) hopping parameters and a partial sounding parameter to a terminal device, wherein the SRS hopping parameters indicate a bandwidth configuration for SRS communication and the partial sounding parameter indicates whether partial sounding across frequency is enabled or not; and receiving SRS sequences from the terminal device based on the SRS hopping parameters and the partial sounding parameter.

An apparatus may initiate a RACH procedure. The apparatus may determine a fractional frequency offset pattern or a cover code across groups of preamble sequences. The apparatus may generate a RACH preamble signal according to at least one of the fractional frequency offset pattern and the cover code. The apparatus may transmit the RACH preamble signal to a network node.

A method for transmitting data by a terminal according to an embodiment of the present invention comprises the steps of: receiving information on the repetition number of transmission for a physical uplink shared channel (PUSCH) from a base station; receiving, from the base station, information on frequency hopping applied to the the PUSCH repetition configuring the the PUSCH repetition; determining a frequency resource for the PUSCH repetition based on the information on the frequency hopping; and performing the the PUSCH repetition.

A user equipment generates an HARQ-ACK codebook comprising HARQ-ACK bits for semi-persistent scheduling (SPS) physical downlink shared channels (PDSCHs) based on multiple SPS configurations, and transmits the HARQ-ACK codebook. In the HARQ-ACK codebook, with respect to an SPS configuration index and a serving cell index, an HARQ-ACK bit for an SPS PDSCH in a slot of a lower slot index precedes an HARQ-ACK bit for an SPS PDSCH in a slot of a higher slot index, and with respect to each serving cell index, an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a lower SPS configuration index precedes an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a higher SPS configuration index.

Methods and devices are provided that enable configuration of a selected set of electronic devices (EDs) that are allocated the same time-domain resources and either orthogonal or the same frequency interlaces on a same unlicensed channel. Configuring the selected set of EDs in order to align transmission starting points in the unlicensed channel and utilizing blocking symbols for at least some of the transmission starting points, may mitigate mutual blocking during LBT procedures.
