Abstract: Aspects of the present disclosure provide techniques to reduce overhead and improve resource management by efficiently selecting RSMA spreading code for periodic traffic in IoE devices. For example, in accordance with one technique, the IoE device, during an initial access to the base station, may notify the base station of the traffic periodicity of the IoE device such that the base station may assign a spreading code from a dedicated pool that is not utilized during the periodic access of the device. Additionally or alternatively, another technique to reduce overhead and improve resource management may include the IoE devices broadcasting the selected RSMA spreading code that the IoE devices intends to use in discovery broadcasts (DBs) along with the IoE device traffic periodicity such that the IoE devices may autonomously manage selection of RSMA spreading code that avoids collisions for the same traffic periodicity.

Abstract: Certain aspects of the present disclosure provide techniques for a multi-user data packet, such as a physical downlink shared channel (PDSCH) packet. A method by a base station (BS) includes sending a control channel, such as physical downlink control channel (PDCCH), scheduling a plurality of user equipment (UEs) for a data packet transmission and sending data for the plurality of UEs in a single transport block on the scheduled data packet. The UE receives the control channel and data packet, and determines the data in the multi-user data packet that is intended for the UE.

Abstract: In some circumstances, a URLLC may preempt resource. An apparatus may be configured to receive a set of resource blocks from a base station including at least one of eMBB data or URLLC data in a PDSCH. The apparatus may receive a URLLC indicator from the base station. The URLLC indicator may be received embedded within the URLLC data or received separate from the URLLC data within DCI of a PDCCH. The URLLC indicator indicates whether the set of resource blocks includes at least part of the URLLC data. The apparatus may determine, based on the URLLC indicator, whether the set of resource blocks includes the URLLC data and processing the set of resource blocks based on a result of determining whether the set of resource blocks includes the URLLC data.

Abstract: Methods and apparatuses are provided which may be used in a base station and/or user equipment (UE) to support or otherwise provide device-to-device (D2D) communication in a shared radio frequency spectrum between candidate UEs. For example, a base station may determine that a first UE and a second UE are candidates for D2D communication, and provide and indicate that a Grant-free Uplink (GUL) resource allocation for D2D communication between the first and second UEs. The base station may further monitor the D2D communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of one or more resources, assigned to multiple UEs, to be used to transmit a channel quality indicator (CQI) report; receive an indication of a threshold value associated with a range of channel conditions corresponding to a modulation and coding scheme (MCS) being used to communicate with the UE; and selectively transmit the CQI report on the one or more resources based at least in part on whether a measured channel condition is outside of the range of channel conditions by at least the threshold value. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to serving wireless communication devices using multi-radio access technology (multi-RAT) transmission diversity are provided. A first wireless communication device communicates, with a second wireless communication device in a first frequency band allocated to a first radio access technology (RAT), first data using the first RAT. The first wireless communication device reconfigures a first resource in a second frequency band allocated to a second RAT different from the first RAT from implementing a configuration of the second RAT to implementing a configuration of the first RAT. The first wireless communication device communicates, with the second wireless communication device in the second frequency band, second data using the first resource implementing the configuration of the first RAT.

Abstract: Transmission time interval (TTI) bundling for ultra-reliable low-latency communication (URLLC) uplink and downlink transmissions is discussed in which a base station or user equipments (UEs) determine conditions for one or more served UEs that would indicate enabling TTI bundling for data and/or control transmissions. The serving base station transmits an enablement signal signifying that TTI bundling will be performed for data and/or control transmissions. The enablement signal may include a bundle length for the transmission bundle. The data or control signal packets may then be repeatedly transmitted to the UEs a number of times corresponding to the bundle length.

Abstract: A device may use sidelink request and sidelink response (e.g., DSS/STS and DRS) resources (in a sub-band) of different sizes depending on whether the sub-band is a primary sub-band or secondary sub-band. The device may transmit more information in the request/response resources of a primary sub-band than in the request/response resources of a secondary sub-band. The device may transmit small amounts of information in its request/response resources in secondary sub-bands. The resources in the secondary sub-bands may include, for example, reference signals, and signals indicating occupation of the sub-band. The device may utilize tone signaling for request/response signaling in the secondary sub-bands (at least because the amount of information being conveyed in the secondary sub-bands is small) and digital signaling in the primary sub-band (at least because the amount of information being conveyed in the primary sub-band is large in comparison to that being conveyed in the secondary sub-bands).
