摘要： 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.

摘要： Techniques are described for wireless communication. One method includes receiving, from a network access device, an uplink grant to transmit over a channel of a shared radio frequency spectrum band. The uplink grant indicates a number of subframes and a transmission window having a duration of a plurality of subframes. The method further includes contending for access to the channel of the shared radio frequency spectrum band based at least in part on a listen before talk (LBT) procedure and in accordance with the uplink grant; and transmitting an uplink transmission over the channel of the shared radio frequency spectrum band, in accordance with the uplink grant/ A starting subframe of the uplink transmission is based at least in part on the LBT procedure and is within the transmission window.

摘要： 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.

摘要： Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

摘要： Various embodiments herein provide techniques for frequency hopping for uplink transmission in advanced duplex systems, e.g., using non-overlapping sub-band full duplex (NOSB-FD) symbols. The frequency hopping may include switching between an NOSB-FD symbol and a non-NOSB-FD symbol. Embodiments further provide techniques for handling collision between uplink transmission and a downlink resource in the NOSB-FD symbol and/or non-NOSB-FD symbol. Other embodiments may be described and claimed.
