More specifically, the method performed by the UE includes: receiving, from a base station, NPRACH configuration information including control information for a repetition number of NPRACH preambles including symbol groups through a higher layer signaling; and transmitting, to the base station, the NPRACH preamble repeatedly through frequency hopping of a symbol group based on the NPRACH configuration information, in which a frequency location of the symbol group is determined based on a first parameter related to a start subcarrier and a second parameter related to the frequency hopping.

Abstract: With sidelink reservation signals sent together with the sidelink data, there is the possibility of interference with other sidelink signals. In order to address this, systems and methods are provided in which a first UE transmits a reservation signal to indicate at least one time-frequency resource for transmitting sidelink data. Following this, the first UE transmits at least one sidelink data transmission to a second UE using the at least one time-frequency resource indicated by the reservation signal. The reservation signal is transmitted before the at least one sidelink data transmission signal so that a third UE may detect the reservation signal and use the reservation signal to avoid using the at least one time-frequency resource indicated in the reservation signal.

Abstract: Disclosed is an electronic device including at least one processor, and at least one memory operatively connected with the at least one processor, wherein the at least one memory stores instructions, which when executed, instruct the at least one processor to receive, on a control channel, a control channel message, receive a set of reference signals (RSs) in which each RS corresponds to a beam direction, decode the control channel message to obtain a list of transmission state indicator (TCI) state information for one or more slots, wherein each TCI state information comprises a channel occupancy time (COT) duration indicator for each of the slots, and determine, based on the TCI state information list, whether each RS of the set is valid.

Abstract: Systems and methods are provided for performing channel estimation in a multiple input multiple output (MIMO) based cellular radio technology (e.g., 4G, 5G). Initially, the reference transmission receive power (RSRP) is reported for each antenna element, rather than as a single RSRP. This enables the base station to understand the channel condition for each MIMO transmission/reception. Using that understanding, the base station can determine the radio-frequency (RF) power level per antenna port to provide more enhanced transmission towards a specific UE, resulting in a better service experience. In other words, more accurate channel estimation based on actual RF conditions of a particular UE can be derived so the base station can tune to the actual need of the UE.

An indication of the resources associated with the COT may be provided by the base station to the UE. The UE may then validate the configured resources based on whether they are located within resources associated with the COT.

Abstract: Provided are a wireless communication apparatus and a reference signal generating method, wherein inter-cell interference is reduced inside and outside a CoMP set. A CoMP mode setting unit (101) sets whether the terminal (100) thereof is a CoMP terminal or a Non-CoMP terminal. When the terminal (100) is set as a Non-CoMP terminal, the hopping pattern calculating unit (104) calculates a ZC sequence number to be used as the transmission timing, from among all the ZC sequence numbers that can be used within the system. When the terminal (100) is set as a CoMP terminal, the hopping pattern calculating unit (104) calculates a ZC sequence number to be used as the transmission timing, by hopping the ZC sequence numbers to be used within the CoMP set. A ZC sequence generating unit (105) generates a ZC sequence to be used as an SRS, using the calculated ZC sequence number.

Abstract: Embodiments of the present invention are drawn to electronic systems that perform EHT operations for a wireless network supporting a 160+160 MHz/320 MHz operating mode. RTS/CTS frame exchange sequences and TXOP truncation can be performed using punctured preambles according to subchannels indicated in a bitmap subfield (e.g., an Allowed Bitmap Subfield). Preamble puncturing is supported for EHT PPDUs transmitted to multiple STAs using MU-RTS/MU-CTS frames transmitted in non-HT duplicate PPDUs. Preamble puncturing is also supported for an EHT PPDU transmitted to a single STA. The RTS and CTS frames can be sent in a non-HT duplicate PPDU with preamble puncturing, for example.

Abstract: User equipment may request to communicate with a basestation over a contention-based wireless communication channel. The basestation and the user equipment may perform a multiple-step random access protocol to determine whether the user equipment may communicate over the wireless communication channel. The architecture, e.g., the fields and structure of the messages sent by the basestation may indicate the content and type of those same messages.

Abstract: This disclosure combines the Attach and Tracking Area Update procedures into one new mobility procedure: the Registration procedure. One advantage of the proposed Registration procedure is that, if the new SHF is unable to obtain UE data from the old SHF the new SHF will nevertheless register the UE so that the UE does not have to perform another registration procedure (e.g., an Attach procedure).

Abstract: Methods, systems, and devices for wireless communications are described to support half-duplex-aware resource selection in sidelink. A physical (PHY) layer at a user equipment (UE) may report available resources to a medium access control (MAC) layer excluding some resources on which the UE is scheduled to receive or other UEs are scheduled to transmit. Specifically, the PHY layer may exclude resources on which the UE is scheduled to receive from a set of resources available for a sidelink transmission from the UE. Similarly, the PHY layer at the UE may exclude resources on which other UEs are scheduled to transmit from a set of resources available for a sidelink transmission to those UEs. A MAC layer at the UE may indicate to the PHY layer (e.g., directly or indirectly) the resources to be excluded when reporting available resources.
