Certain aspects of the present disclosure provide techniques for randomized frequency locations for uplink grants. The uplink grants may be Type-1 uplink grants. The uplink grants may be used to schedule resources for ultra-reliable low-latency communications (URLLC) in new radio (NR) or 5G access. Aspects provide a method for wireless communication by a base station (BS). The BS transmits one or more uplink grants configuring a set of user equipments (UEs) with a plurality of transmission opportunities (TOs) available for uplink transmission by the set of UEs and a plurality of frequency locations associated with each TO. The BS configures the set of UEs for randomly determining one of the plurality of associated frequency locations for each of the configured TOs, for uplink transmission. The BS receives uplink transmissions from at least two of the set of UEs in at least one of the configured TOs at different frequency locations.

The present specification relates to a method for transmitting uplink signals in a wireless communication system, the method being performed by a UE and comprising the steps of: receiving, from a base station, information on a cyclic shift (CS) index configuration, which indicates the configuration of an index group for a CS related to uplink signal transmission; determining a CS index for generating a particular uplink signal in the CS index group; generating the particular uplink signal by using the determined CS index and a base sequence having a particular length; and transmitting the generated particular uplink signal to the base station via an uplink control channel.

Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) resource configuration enhancements. A method generally includes receiving, from the network, a message comprising sounding reference signal (SRS) configuration information, wherein the SRS configuration information comprises configuration information for a first SRS resource set and configuration information for a second SRS resource set and transmitting at least one SRS according to the received SRS configuration information.

An eNodeB (eNB), Machine Type Communications (MTC) user equipment (UE) and method using a physical uplink control channel (PUCCH) in a non-legacy PUCCH region are generally described. The UE may be in an enhanced coverage (EC) mode. The UE may receive higher layer signaling indicating physical resource blocks in the PUCCH region and offsets in a cell- or UE-specific manner on a per-slot basis or, when in EC mode, per-set of N subframes basis. The UE may receive a resource allocation for a PUCCH in a PUCCH region separate from a legacy PUCCH region and reserved for non-legacy UEs. The UE may transmit a frequency hopping PUCCH in the PUCCH region and use shortened PUCCH format to accommodate an extended retuning time by puncturing a first and/or last symbol of at least one slot. If retuning, the UE may drop a sounding reference signal transmission in the next subframe.

The present specification relates to a method for transmitting uplink control channels in a wireless communication system, the method being performed by a terminal and comprising the steps of: receiving, from a base station, information on a cyclic shift (CS) index configuration, which indicates the configuration of an index group for a CS related to uplink control channel transmission; transmitting a first physical uplink control channel by using a first CS index included in the CS index group and a base sequence having a particular length; and transmitting a second physical uplink control channel by using a second CS index included in the CS index group and the base sequence having the particular length, wherein the first CS index is used for symbols that are not overlapped between transmission time intervals (TTI) for transmitting the physical uplink control channel, and the second CS index is used for symbols that are overlapped between the TTI.

Provided is a method for performing transmission of an uplink channel in a wireless communication system, the method being performed by a terminal and comprising the steps of: receiving a system information block 1 (SIB1) from a base station; transmitting a preamble for a random access procedure to the base station; receiving a random access response (RAR) to the preamble from the base station; and transmitting a PUSCH to the base station on the basis of the random access response.

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.

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.
