Wireless transmission may be based on a listen-before-talk (LBT) procedure indicating a clear channel. One or more transmissions may start from a configured starting position. The configured starting position may be signaled to a wireless device.

Aspects described herein relate to determining a configuration indicating multiple synchronization points, in time, for contention-based communications, determining, for a given synchronization point of the multiple synchronization points, a contention window using a deterministic function based at least in part on one or more configured parameters, and transmitting, during the contention window, one or more contention-based signals in an attempt to acquire a channel for transmitting communications.

A method and a user equipment (UE) for timing alignment is provided. The method includes maintaining a Timing Advance (TA) value as a first TA value; receiving, from a Base Station (BS), a TA command during a Random Access (RA) procedure; applying the TA command to set the TA value to a second TA value included in the TA command in a case that a first timing alignment timer is not running; determining whether a contention resolution for the RA procedure is successful; and when the contention resolution is not successful, setting the TA value to the first TA value in a case that a Configured Grant-based Small Data Transmission (CG-SDT) procedure is ongoing.

To appropriately control UL transmission such as a CSI reporting when performing communication by applying a different configuration from those of legacy LTE systems, a user terminal according to one aspect of the present disclosure includes: a transmission section that transmits one or more UL signals by using an uplink shared channel based on an instruction from a base station; and a control section that controls the transmission assuming that transmission durations of a plurality of UL signals do not overlap in a same symbol, or, when at least part of the transmission durations of the plurality of UL signals overlap in the same symbol, performs control to select and transmit the part of the UL signals.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, initial timing advance information in a msg2 communication of a four-step random access channel procedure based at least in part on a subcarrier spacing in a cell associated with the base station. The UE may transmit, and the base station may receive, a msg3 communication with an initial timing advance that is based at least in part on the initial timing advance information. The base station may transmit, and the UE may receive, updated timing advance information resolving a timing advance wrap-around between the UE and the base station based at least in part on the base station detecting the msg3 communication. Numerous other aspects are provided.

Configuration parameters for a wireless device may comprise an energy detection threshold offset that may be used to adjust an energy detection threshold of an listen-before-talk (LBT) procedure. One or more transmissions may be based on the LBT procedure indicating a clear channel. The one or more transmissions may start from a configured starting position.

A method for operating a wireless control device includes the starting up of a control circuit following the actuation, by a user, of a control unit coupled to an energy harvesting device to recharge an energy reserve which electrically powers the control device; the sending of a control message including a control command; the comparison of the elapsed time since the starting up of the control circuit with a first threshold value; when the elapsed time is greater than or equal to the first threshold value, the sending of a pairing request message to the electronic unit.

A random access channel (RACH) procedure allows a user equipment (UE) to achieve synchronization with a network and obtain network resources and services from a scheduling entity. This disclosure provides various options for implementing a two-step RACH procedure that can support various UE behaviors in relation to using or not using a time symbol gap between a physical random access channel (PRACH) resource and a physical uplink control channel (PUCCH) resource.

A typical Software Defined Radio (SDR) receiver for Binary Phase Shift Keying (BPSK) or higher order modulations accepts an incoming digital serial complex I/O channel sample stream and performs demodulation functions to recover the original baseband data stream that another source transmitted. Typically, for real-time high data rate (HDR)>5.0 Megabits per second (Mbps) operations, a SDR unit requires an Application Specific Integrated Circuit (ASIC) component or Field Programmable Gate Array (FPGA) component to perform the customized Digital Signal Processing (DSP) intensive processing functions in real-time. However, ASIC chips and FPGAs are typically relatively expensive to develop, purchase, and/or reconfigure. With the parallel multi-core algorithm method of this claim, one can now implement a real-time HDR (>5.0 Mbps) SDR Demodulator with only Commercial-Off-The-Shelf (COTS) software, a relatively inexpensive personal computer (PC) or server that contains a single multi-core General Purpose Processor (GPP), and especially without using ASICS or FPGAs.
