Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Abstract: The present disclosure describes various aspects of the implementation and design of Physical Downlink Control Channel (PDCCH) in 5G new radio (NR) applications. Aspects include methods, apparatuses, and computer-readable medium for one or more of multiple PDCCH search spaces, control resource block (CRB), irregular multiple slots or mini-slots grants, or fast control channel signaling for grant-free uplink (UL). For example, different scheduling entities can each have one or two search spaces defined (e.g., common and/or user equipment (UE)-centric search spaces). Also, CRBs can be used as units for PDCCH transmission instead of resource element groups/control channel elements (REGs/CCEs). In addition, irregularities in time domain, frequency domain, or both can be introduced in the granting of resource blocks (RBs) over multiple slots or mini-slots. Moreover, signaling can be used to indicate to a UE configured for grant-free UL the portion of the pool of resources available for grant-free UL.

Abstract: Idle discontinuous reception (I-DRX) cycles at a user equipment (UE) may be extended via leveraging of paging assistance from a second UE. For example, a low complexity UE may have a connection to a network (e.g., via a link to a base station) as well as a connection to another UE (e.g., via a device-to-device link to a regular UE). In cases where such a low complexity UE receives paging messages from the network, a UE associated with a device-to-device link of the low complexity UE may monitor paging messages on behalf of the low complexity UE. As such, the low complexity UE may extend its I-DRX cycle, as the assisting UE monitors paging information for the low complexity UE. The assisting UE may forward paging information for the low complexity UE according to paging occasions of the extended I-DRX cycle of the low complexity UE.

Abstract: Methods, systems, and devices for wireless communications are described. An encoding device (e.g., a user equipment (UE) or a base station) may divide one or more data units (e.g., packet data convergence protocol (PDCP) protocol data units (PDU)) into a set of data blocks. The encoding device may encode the set of data blocks using a fountain code and may generate a set of data units (e.g., radio link control (RLC) PDUs) based on encoding the set of data blocks using the fountain code. The UE may allocate a first subset of the set of data units to a first carrier and a second subset of the set of data units to a second carrier and may transmit the first subset over the first carrier and the second subset over the second carrier.

Abstract: A user equipment (UE) may map a demodulation reference signal (DMRS) sequence to a first symbol in a set of resource blocks (RBs) of an uplink long burst, and the first symbol may occur at the beginning of the uplink long burst. The DMRS sequence may be “front-loaded” in the uplink long burst. The DMRS sequence may be dependent upon RB locations. When the DMRS sequence is mapped to the beginning of an uplink long burst, uplink control information (UCI) may be mapped in a physical uplink shared channel (PUSCH). A UE may map UCI in a PUSCH after the DMRS sequence is mapped to the beginning of the uplink long burst. When the base station receives an uplink long burst including the front-loaded DMRS and the UCI mapped in the PUSCH, the base station may identify the DMRS for channel estimation/interference cancelation of the UCI carried on the PUSCH.

Abstract: Disclosed are techniques related to wireless communication system to enable full duplex communication. A network node is configured to communicate with a parent node and a child node. The network node may include a transceiver, a memory, and a processor communicatively coupled to the transceiver and the memory. The transceiver, memory, and processor may be configured to determine uplink (UL) parent and child link priorities for parent and child time-domain resources that overlap in time at least partially. The transceiver, memory, and processor may also be configured to determine UL parent and child beams based on the UL parent and child link priorities. The transceiver, memory, and processor may further be configured to notify the parent node of the UL parent beam for the parent and child time-domain resources. The transceiver, memory, and processor may yet further be configured to concurrently transmit parent traffic to the parent node using the UL parent beam and receive child traffic from the child node using the UL child beam.

Abstract: Wireless communications systems and methods related to system information communications and decoding are provided. In one embodiment, a wireless communication device receives one or more known bits. The wireless communication device receives a first encoded information block. The wireless communication device decodes the first encoded information block to generate a first information block based on the one or more known bits. In one embodiment, a wireless communication device receives a first encoded information block including a first bit pattern. The wireless communication device receives a second encoded information block including a second bit pattern. The wireless communication device jointly decodes the first encoded information block and the second encoded information block based on an assumption that a difference between the first bit pattern and the second bit pattern is within a subset of a plurality of bit-change patterns.

Abstract: Various aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive a master information block that identifies a first control resource set (CORESET) for a first category of UEs and a first common search space (CSS) associated with the first CORESET. The first CORESET and the first CSS may identify one or more overlapping resource grids that overlap in time and frequency with one or more corresponding resource grids of a second CORESET and a second CSS, associated with the second CORESET, for a second category of UEs, and one or more non-overlapping resource grids that include a corresponding one or more time domain resources that are earlier than a time domain resource of the second CORESET and the second CSS. The UE may monitor for a physical downlink control channel candidate included in the first CORESET and the first CSS.

Abstract: Methods, systems, and devices for wireless communications are described for enabling a network equipment to reduce interference for downlink (DL) transmissions to a first device by determining a transmit precoding matrix indicator (TPMI) for uplink (UL) transmissions transmitted by a second device based on feedback from the first device. The first device may determine a subset of possible TPMIs that the second device may use for UL transmissions for full-duplex communications. The first device may indicate the subset to the network equipment. Based on the subset indicated by the first device, the network equipment may determine a pairing of the first device and the second device for full-duplex communications. Additionally, the network equipment may determine a TPMI for the second device to use in UL transmissions and indicate the TPMI to the second device.
