Disclosed are techniques for wireless communication. In an aspect, a UE determines a configuration of a common PUCCH resource set that is based on a frequency hopping pattern and includes a first set of resource blocks (RBs) of a bandwidth part (BWP) in a first group of symbols and a second set of RBs of the BWP in a second group of symbols.

Modulation scheme in a wireless communication system
A system and method of DFT-S-OFDM modulation is provided that uses a set of frequency domain patterns. For a given transmitter, for a set of DFT-S-OFDM symbols, the frequency domain pattern changes according to a time domain hopping pattern. Advantageously, the time domain hopping patterns are defined to allow only a certain amount of overlap, for example for only one DFT-S-OFDM symbol, between any two time domain hopping patterns. This functions to reduce the effect of a collision, when two transmitters use the same frequency pattern, they will do so only for part of the overall transmission. Optionally, frequency domain spectral spreading is used in the transmitter. This can further reduce the PAPR. In the receiver, successive interference cancellation may be employed to reduce the effect of colliding transmissions.
Wireless remote monitoring system and data collection and control and method of using the same
System and method for collection, control and wireless transmission of environmental and other data. Nodes may wirelessly connect to other nodes to relay node specific information, collected sensor data or commands to and from other nodes and gateway nodes linked to a central database. Nodes in gateway mode may be capable of aggregating and relaying commands and data between other nodes and a centralized database. Nodes may bypass other nodes and/or gateway nodes and communicate directly with the central database via satellite or cellular link. Nodes may be self-contained devices, inclusive of a wind or solar power source and a battery, eliminating the need for an external power source. Nodes may be configured independently or as a system to monitor and control various types of equipment including utility lines or water systems or used to collect environmental data. Nodes may communicate on different channels/frequencies based on systematic or pseudo-random changes.
