Abstract: An interference randomization method in a user equipment, UE, and a corresponding UE are disclosed. A set of control information bits comprising ACK/NACK bits are encoded to generate encoded control information bit. The encoded control information bits are scrambled to generate scrambled control information bits and the scrambled control information bits are modulated to generate modulated symbols. A physical uplink control channel, PUCCH, ACK/NACK resource index is determined and a first orthogonal sequence index, a second orthogonal sequence index, and a cyclic shift for a demodulation reference signal, DMRS, are determined wherein each of the first orthogonal sequence index, the second orthogonal sequence index, and the cyclic shift is determined based the PUCCH ACK/NACK resource index. The modulated symbols are speaded block-wise using a first orthogonal sequence indicated by the first orthogonal sequence index and a second orthogonal sequence indicated by the second orthogonal sequence index and the cyclic shift to the DMRS are applied. The DMRS and the block-wise spread modulated symbols are transmitted on a PUCCH.

Abstract: Methods, systems, and apparatuses for wireless communication are described. In some wireless systems (e.g., new radio (NR) systems), a system may employ fixed or variable length uplink burst regions (e.g., in an uplink-centric slot). The base station may semi-statically or dynamically configure a user equipment (UE) or group of UEs for uplink control channel transmissions within an uplink burst region. In semi-static configuration, the UE may determine the uplink control channel transmission based on values transmitted or indicated via higher-layer signaling or based on default values. In dynamic configuration, the UE may receive an indication of actual resources used by the base station in a physical layer message. The UE may transmit using an uplink control channel transmission based on the indication. In some cases, the base station may allocate code division multiplexing (CDM) groups based on which UEs are semi-statically configured and which are dynamically configured.

Abstract: A sounding reference signal transmission method which is efficient in an uplink wireless telecommunications system using a multiple antenna technique and sounding reference signal hopping. A terminal using the multiple antenna technique is equipped with a plurality of antennas, and a base station receives the sounding reference signal transmitted from these antennas and estimates the uplink channel state of each antenna. Moreover, the sounding reference signal performs frequency hopping so that the base station determines the channel condition for the entire bandwidth to which data is transmitted in the uplink system. The sounding reference signal is transmitted through an antenna pattern in which the sounding reference signal can be transmitted through the entire data transmission bandwidth of the uplink system for each antenna of the terminal without additional overhead in this environment.
