Abstract: Design of precoding and feedback for user equipment (UE)-specific reference signals (UE-RS)-based open-loop and semi-open-loop multiple input, multiple output (MIMO) systems is discussed. Aspects of the present disclosure provide for sub-resource block (RB) random precoding that allows for greater diversity gain in a lower bandwidth. In addition, the recoding may be performed using resource element (RE)-level layer shifting that provides for a number of precoders to be assigned to a number of layers for every such continuous subcarrier. As such, two codewords may experience the same effective channel quality with channel quality indicators (CQI) being averaged across all of the layers.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided for cross-carrier scheduling when both PDCCH and EPDCCH are employed in a network that supports carrier aggregation. The apparatus receives a first component carrier and a second component carrier, where the first component carrier includes a first control channel, a second control channel, and carrier indication information. The first control channel corresponds to the first component carrier. The second control channel and the carrier indication information correspond to the second component carrier. The second control channel is one of at least a first type (e.g., PDCCH) or second type (e.g., EPDCCH) of control channel and the carrier indication information identifies the second component carrier for both the first and second types of control channels. The apparatus then processes the first and second control channels.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to a physical uplink control channel (PUCCH) sequence design. In some cases, a UE receives (from a network entity, such as a base station/gNB) signaling indicating a base sequence from a set of base sequences available for use in sending one or more bits of uplink control information (UCI) within a transmission time interval (TTI), receives signaling indicating a set of feasible cyclic shifts, selects one of the cyclic shifts based on a value of the one or more bits of UCI, and transmits the UCI using the base sequence and the selected cyclic shift.

Abstract: Various aspects described herein relate to techniques for uplink transmissions in wireless communication systems. In an aspect, a method includes receiving, by a user equipment (UE), hopping information for two consecutive symbols, generating, by the UE, a first symbol of the two consecutive symbols using a format, generating, by the UE, a second symbol of the two consecutive symbols based on the format and the hopping information, and transmitting, by the UE, the two consecutive symbols in an uplink signal.

Abstract: A method and apparatus for improved transmission of ACK and NACK bits to a base station The example method may determine a distance between a first UE and a second UE based on one or more of a sequence length, a number of hypothesis, or a number of UEs sharing an OFDM symbol. The example method may determine a plurality of cyclic shifts for each of the first UE and the second UE. The example method may assign one or more sequences to each UE. The example method may receive, at the base station, a multiplexed signal, wherein the multiplexed signal includes at least one bit of uplink control information (UCI) from the first UE and the second UE multiplexed on an uplink short burst transmitted via the OFDM symbol. The method may enable the receipt of UCI from multiple UEs in a multiplexed signal.

Abstract: A method and apparatus for enabling an UE to selecting acknowledgement/non-acknowledgement (ACK/NACK) resources from a subset of a gNB resource pool. The example method may receive, from an gNB, a radio resource control (RRC) configuration indicating a UE-specific resource set that is a subset of a gNB resource pool. The UE may determine one or more ACK/NACK resources from the UE-specific resource set for an upcoming physical uplink control channel (PUCCH). In some aspects, the UE may determine the one or more ACK/NACK resources based on receiving, from the gNB, a physical downlink control channel (PDCCH) including a corresponding ACK/NACK resource configuration. In other aspects, the RRC may contain multiple resource subsets and the UE may determine the one or more ACK/NACK resources based on determining a size of a payload for a UCI to be transmitted on the PUCCH. The aspects may thus enable dynamic ACK/NACK resource allocation.

Abstract: Aspects described herein relate to communicating feedback in wireless communications. A user equipment (UE) can receive, in a downlink portion of a slot, data communications from a base station, where the data communications comprise multiple code blocks received in one or more downlink symbols. The UE can generate one or more feedback bits to provide feedback for the multiple code blocks. The UE can transmit, to the base station and in an uplink portion of the slot, an indication of the one or more feedback bits

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided that may be configured to receive a downlink control message, to determine a beta offset value for transmitting UCI based at least in part on the downlink control message, and to transmit the UCI on an uplink shared channel interleaved with data based on the determined beta offset value. The apparatus may identify the beta offset from a set of values based on the downlink control message. An apparatus may identify resources allocated for PUSCH and may map UCI to the identified resources for PUSCH in a frequency interleaved manner over a bandwidth of the identified resources. The apparatus may map data to the identified resources in a time-first or frequency-first manner, and may transmit a signal comprising UCI and data on the identified resources of the PUSCH in accordance with the mapping.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a cell identifier is selected based on one or more properties associated with received downlink control information (DCI), where the properties may not be exclusively associated with determining a cell identifier. The cell identifier may be selected from a plurality of cell identifiers received through radio resource control signaling. The properties of the DCI may include a type of download control channel, a type of subframe and a type of DCI format used to provide the DCI.
