Abstract: The techniques described herein may provide for sub-slot based physical uplink shared channel (PUSCH) repetition (i.e., back-to-back PUSCH repetition within a slot) according to user equipment (UE) capability. A UE may employ uplink data repetition capability reporting for base station scheduling of uplink data repetition and base station management of the number of transport blocks (TBs) that a UE supports (e.g., processes and transmits for uplink) on a per-slot basis. According to the techniques described herein, a UE may indicate whether it supports mini-slot repetition (e.g., for ultra-reliable low-latency communication (URLLC), enhanced mobile broadband (eMBB), or both) via an uplink data repetition capability report. The uplink data repetition capability report may further indicate a maximum number of supported repetitions per TB, a number of supported TBs per slot, etc., such that a base station may configure or schedule PUSCH repetition based on the UE's reported capability.

Abstract: Since multiple transmit-receive point (TRP) communications may increase the number of physical downlink control channel (PDCCH) candidates without increasing the number of cells, new limits for multi-TRP communications may be defined. A UE may determine a PDCCH monitoring capability across all downlink serving cells that may account for multiple-TRP cells and for carrier aggregation and dual connectivity using a multiplication factor. Further, the UE may determine a limit of a number of serving cells based on the capability and a configuration of serving cells. The UE may determine a total limit of PDCCH candidates and non-overlapped control channel elements (CCEs) to monitor in a slot for a cell group and a per cell limit single TRP cells and for multiple TRP cells based on the limit of the number of serving cells. Alternatively, the limits may be defined per control resource set (CORESET) group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information identifying one or more control channel monitoring span capabilities. The UE may receive, from the base station, information identifying a plurality of control channel monitoring occasions. The UE may generate a bitmap based at least in part on the plurality of control channel monitoring occasions. The UE may determine, in accordance with the bitmap and based at least in part on the information identifying the one or more control channel monitoring span capabilities, a span pattern indicating one or more locations of one or more spans in a slot. Numerous other aspects are provided.

Abstract: Signaling strategies for an advanced receiver with interference cancellation (IC) and suppression is discussed. Upon enablement of an advanced interference cancellation procedure according to the disclosure, transmitters within the enabled area transmit according to transmission restriction configurations that provide transmission limits based on either frequency, time, or scheduling. The restrictions on the transmitters reduces the complexity of processing by neighboring advanced receivers for cancellation of interference from the restricted transmitters. At the advanced receiver, transmission information, such as scheduling, reference signal (RS), resource block (RB) allocation, and the like, may either be determined through blind detection or received directly through signaling. The advanced receiver may use this transmission information associated with each interfering signal to detect, decode, and subtract the interfering signals from the received transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication from a base station to transmit one or more sounding reference signals (SRSs) on respective component carriers (CCs). Each CC may be associated with a different numerology and the UE may determine a transmission timing between reception of the indication and transmission of each of the SRSs based on the numerology for the CC used for transmission. In some cases, the UE may determine the transmission timings based on time durations associated with each numerology, which may be based on a number of symbols for the numerology, a corresponding time between receiving the indication and transmitting uplink data (e.g., SRS), or a combination thereof. The UE may transmit, to the base station, each SRS according to the determined transmission timings.

Abstract: Methods, systems, and devices for wireless communications are described that support time division duplexing (TDD) for dual connectivity (DC) to different radio access networks (RANs). A DC connection may be established between a user equipment (UE) and both a first RAN and a second RAN. A reference TDD configuration for the first RAN and a designated TDD configuration for both the first and second RAN may be identified. The designated TDD configuration may have a first set of uplink subframes and the reference TDD configuration may have a second set of uplink subframes that is a subset of the first set of uplink subframes. Downlink transmissions of the first RAN may be transmitted according to the reference TDD configuration, and uplink transmissions of the first and second RAN may be transmitted according to the designated TDD configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station by initiating a random access procedure with a two-root preamble. The UE may receive, from the base station, control signaling that indicates a set of root preamble sequences. The UE may transmit, to the base station, a preamble signal that is generated based on a first root preamble sequence and a second root preamble sequence of the set of root preamble sequences. The UE may then monitor for a preamble response based on the preamble signal. In some cases, the base station may be a base station in a terrestrial network. In other cases, the base station may be a satellite in a non-terrestrial network (NTN).

Abstract: Methods, systems, and devices for wireless communications are described that support splitting resources among different types of control information and uplink data for transmission on an uplink shared channel. A base station may transmit a grant indicating resource elements (REs) of an uplink shared channel allocated to a user equipment (UE) for an uplink transmission. The UE may process the grant and split the granted REs between different types of uplink control information (UCI) and uplink data based on a reference payload size. The UE may generate an uplink transmission based on the splitting of the REs, and may transmit the uplink transmission in the REs of the uplink shared channel indicated in the grant. The base station may monitor the REs of the uplink shared channel for the uplink transmission in accordance with the splitting of the plurality of REs.

Abstract: Aspects and techniques relate to scheduling resources for uplink transmissions in wireless communication systems. In some examples, an allocation of resources for uplink may be based on a common reference resource (e.g., a reference physical resource block, PRB) also used for allocation of resources for downlink In other examples, allocation of resources for uplink may be based on a different reference resource. A scheduler may further provide an indication whether the same, common reference resource is used, or a different reference resource. A scheduler may further indicate a different reference resource as needed. Other aspects, embodiments, and features are also claimed and described.

Abstract: The present methods and apparatus enable transmission of an interlaced reference signal for two UEs using a comb structure. In some aspects, the present methods and apparatus may allocate resources and indicate whether a first UE and a second UE are to transmit DM-RS with a comb structure in a single slot based on the allocation. Further, in some aspects, the present methods and apparatus may allocate resources and transmit information indicating whether a first UE is to transmit DM-RS in a first slot or in both a first slot and a second slot within a subframe.
