This disclosure provides systems, methods, and devices for wireless communication that support managing allocation of configured grant (CG) resources for uplink transmissions using a polynomial over Galois field in a wireless communication system. In particular, a user equipment (UE) may be configured (e.g., by a base station) to determine a resource to access, from a resource pool configured for each CG occasion of a CG configuration, based on a polynomial over Galois field configured for the UE. The polynomial over Galois field may include a parameter p, and the UE may be configured with a mapping that maps the absolute time (e.g., a slot index or a symbol index) of a GC occasion to an index between 0 and p−1 that is used as input to the polynomial The result of the polynomial is used to determine the resource to access by the UE at the CG occasion.

There is provided mechanisms for enabling OTA estimation of a radio frequency parameter of a radio transmitter during a test time interval. The radio transmitter is configured for transmission in a set of beams. A method is performed by a controller of the radio transmitter. The method comprises identifying a subset of beams in the set of beams that, during the test time interval, are unused for transmission of scheduled signals. The method comprises instructing the radio transmitter to transmit, during the test time interval, an unscheduled signal in the subset of beams, whilst also transmitting the scheduled signals in those beams of the set of beams that are used for transmission of the scheduled signals, for enabling estimation of the radio frequency parameter of the radio transmitter.

A method for performing wireless communication by a first device is proposed in an embodiment. The method may comprise the steps of: selecting a synchronization source on the basis of a sidelink synchronization priority; acquiring synchronization on the basis of the synchronization source; transmitting a sidelink-synchronization signal block (S-SSB) to a second device on the basis of the acquired synchronization; transmitting, to the second device, information related to a pattern of a physical sidelink shared channel (PSSCH) demodulation reference signal (DMRS) for decoding a PSSCH through sidelink control information (SCI) on a physical sidelink control channel (PSCCH); mapping the PSSCH DMRS onto a time resource related to the PSSCH on the basis of the information related to the pattern of the SSCH DMRS and an interval of a time resource scheduled for transmission of the PSSCH related to the PSCCH; and transmitting the PSSCH DMRS to the second device through the PSSCH.

A method and a device in a node for wireless communications. A first receiver receives a first signaling; a first transmitter transmits a first signal in a first time-frequency resource pool, the first signal carries a first bit block; herein, the first signaling is used to determine the first time-frequency resource pool; the first bit block comprises K HARQ-ACK information bit(s); a first condition is a condition related to type(s) of HARQ-ACK comprised in the first bit block; when the first condition is not satisfied, a same offset value is used to determine both a number of time-frequency resource element(s) comprised in a first time-frequency resource sub-pool and a number of time-frequency resource element(s) comprised in the first reserved resource pool; when the first condition is satisfied, two different offset values are respectively used to determine a number of time-frequency resource element(s) comprised in a first time-frequency resource sub-pool.

Provided is a method for a user equipment (UE). The UE obtains, from a network device, a first configuration information. The first configuration information indicates a first resource set for an aperiodic Sounding Reference Signal (AP-SRS). The first resource set for the AP-SRS includes a first list of slot offsets. The UE decodes a second configuration information from the network device. The second configuration information indicates a reference slot and a first slot offset of the first list of slot offsets. The UE generates the AP-SRS for transmission to the network device based on the reference slot and the first slot offset.

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.

A method for determining a resource for a reference signal includes: determining, according to positions of N channel resource units used by a physical channel, R channel resource units from the N channel resource units, where both R and N are integers and 0 ≤ R < N; and sending or receiving reference signals in the R channel resource units.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive single downlink control information (DCI) that indicates resources for a plurality of transmission configuration indicator (TCI) states for transmitting or receiving communications in a plurality of transmission time intervals (TTIs). The UE may transmit or receive the communications in the plurality of TTIs in accordance with the DCI. Numerous other aspects are provided.

Embodiments of the present disclosure relate to methods, devices and computer storage media for communication. A method comprises determining, at a network device, a variable for transform pre-coding to be performed by the network device or a terminal device served by the network device; and transmitting, to the terminal device, information about the variable for the transform pre-coding. Embodiments of the present disclosure can achieve high resource efficiency and low PAPR at the same time in downlink transmissions.

Aspects of the present disclosure provide techniques for configuring and triggering aperiodic channel state information (A-CSI) reporting via a downlink grant. As will be described in greater detail below, the A-CSI report may be conveyed via a physical uplink control channel (PUCCH).
