The present disclosure relates to combinable a sub-resource block (RB) sounding reference signal (SRS) transmission for coverage enhancement. Specifically, a network entity may transmit, and a user equipment (UE) may receive a sub-RB SRS configuration message, and a transmit one or more sub-RB SRS. The UE may receive a sub-RB SRS configuration message and transmit one or more sub-RB SRS.

Combinable a sub-resource block (RB) sounding reference signal (SRS) transmission for coverage enhancement

Methods, systems, and devices for wireless communications are described. A group of random access channel opportunities are identified over which to transmit a preamble associated with a random access channel procedure. A preamble sequence group associated with the identified group of random access channel opportunities is determined based on a repetition level associated with the preamble sequence group. At least one downlink message associated with the random access channel procedure is received based on the repetition level.

Techniques for narrowband transmissions with finer granularity of reserved resources. A method that may be performed by a user equipment (UE) includes receiving a configuration indicating first resource elements (REs) reserved from being used for narrowband Internet of things (NB-IoT) transmissions in a subframe; determining second REs, in the subframe, for narrowband reference signals (NRSs), based on the configuration; and processing the NRSs on the second REs in the subframe.

Narrowband transmissions with finer granularity of reserved resources

Certain aspects of the present disclosure provide techniques for channel state information (CSI) for multiple transmission reception point (mTRP) scenarios. The techniques may provide for dynamic interference measurement for mTRP CSI. A method that may be performed by a user equipment (UE) includes receiving a CSI reporting configuration configuring the UE with a plurality of CSI reference signal (CSI-RS) resources for channel measurement (CMRs) and a plurality of resources for interference measurement (IMRs). The method includes determining an indicator based on an association between one or more CMRs and one or more IMRs. A codepoint of the indicator is associated with an IMR or a set of IMRs by an order of the IMRs or the set of IMRs in the configuration, and is associated with a CMR, a CMR pair, or a part of the ports of a CMR. The method generally includes performing CSI measurement based on the association.

Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may determine wide beam parameters for beamformed communications with a base station based on an identified narrow beam. A UE may receive a reference signal from a base station and identify a narrow beam based on measurements of the received reference signal. Based on the identified narrow beam, the UE may determine a set of wide beam parameters for a wide beam that is to be used for communications between the UE and the base station. The wide beam may have a beam direction that corresponds to a direction of the identified narrow beam, and may have a beam width that is determined as a multiple of a beam width of the identified narrow beam (e.g., x times the beam width of the narrow beam).

Channel state information reporting techniques for wide beams

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal configuring a set of random access opportunities over which to transmit a preamble associated with a random access procedure, each random access opportunity associated with a set of one or more uplink data opportunities. The UE may identify a repetition parameter for an uplink message. The UE may select a random access opportunity from the set of configured random access opportunities for transmitting the preamble based at least in part on the repetition parameter. The UE may transmit the preamble on the selected random access opportunity. The UE may transmit one or more repetitions of the uplink message based at least in part on the set of one or more uplink data opportunities associated with the selected random access opportunity.

Aspects of the disclosure relate to wireless communication including mode division multiplexing of data and reference signals using different orbital angular momentum (OAM) modes. An OAM transmitter may transmit a reference signal (RS) configuration information to an OAM receiver that indicates radio resources for a plurality of OAM modes. The OAM transmitter may further transmit data on a first OAM mode of the plurality of OAM modes using first radio resources of the radio resources indicated by the RS configuration information. The OAM transmitter may further transmit a reference signal on a second OAM mode of the plurality of OAM modes using the first radio resources of the radio resources indicated by the RS configuration information. The OAM receiver may receive the data on the first OAM mode and the reference signal on the second OAM mode. Other aspects, embodiments, and features are also claimed and described.

Methods, systems, and devices for wireless communications are described. In some systems, a device may select antenna elements from a planar array to transmit or receive an orbital angular momentum (OAM) beam. The device may determine a first area (e.g., a first ring area) based on an angular direction over which the device can communicate an OAM beam with a second device and may determine a second area (e.g., a second ring area) on the planar array based on projecting the first area on the planar array. The device may select a set of antenna elements from the planar array that are located within the second area. The device may determine a complex-valued weight for each antenna element of the selected set of antenna elements and may transmit or receive an OAM beam to or from the second device via the set of antenna elements according to the angular direction.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adjust resources (e.g., time resources, frequency resources) used to transmit repetitions of uplink control information (UCI) over a physical uplink control channel (PUCCH). The UE may adjust two parameters corresponding to different scales (e.g., levels) of adjustment, where a first parameter corresponds to a number of repetitions of a PUCCH resource and a second parameter corresponds to a number of slots within each PUCCH repetition. The UE may adjust the resources based on the first parameter, the second parameter, a size of UCI, a maximum coding rate, or some combination thereof, such that the PUCCH resources carrying UCI satisfy the maximum code rate and UCI size.
