Abstract: Mechanisms for cross-carrier scheduling from a first cell to a second cell in a wireless networking scheme are provided. In one aspect, a method for wireless communication includes: receiving, from a base station (BS), a first configuration for scheduling in a first cell, the first configuration comprising at least one of a first monitoring periodicity parameter or a first monitoring offset parameter associated with a search space in a second cell different than the first cell; receiving, from the BS, a second configuration for scheduling in the second cell, the second configuration comprising at least one of a different second monitoring periodicity parameter or a different second monitoring offset parameter associated with the search space in the second cell; and monitoring, in the search space in the second cell based on the first configuration and the second configuration, for downlink control information (DCI).

Abstract: Various aspects described herein relate to techniques for communications in a coordinated multi-point (CoMP) wireless communications system. In an aspect, a method of wireless communications may include receiving a request to form a CoMP cluster set of transmit/receive points (TRPs) for a user equipment (UE), determine the CoMP cluster set of TRPs for the UE based on at least a delay budget and a reliability requirement, and one or more of configuration information and measurements, and coordinate communications for the UE using the CoMP cluster set. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Certain aspects of the present disclosure provide enhancements to enable per transmission reception point (per-TRP or per beam group) based beam failure recovery (BFR), and more particularly, techniques for configuring physical uplink control channel (PUCCH) BFR for TRP specific BFR. A method that may be performed by a user equipment (UE) includes communicating using beams associated with at least two beam groups, transmitting a beam failure recovery request (BFRQ) specific to a first beam group of the at least two beam groups based on a detected beam failure in the first beam group, and receiving a response to the BFRQ based, at least in part, on how the BFRQ is transmitted.

Abstract: Methods, systems, and devices for wireless communications are described. A first transmission/reception point (TRP) may coordinate with a second transmission/reception point to configure code division multiplexing group hopping for a user equipment (UE). The first TRP may transmit a signal to the UE indicating that code division multiplexing group hopping is enabled for the first transmission/reception point and the second transmission/reception point. The first TRP may transmit, during a first instance of the code division multiplexing group hopping, a first reference signal to the UE according to a first code division multiplexing group. The first TRP may transmit, during a second instance of the code division multiplexing group hopping, the first reference signal to the UE according to a second code division multiplexing group.

Abstract: This disclosure provides systems, methods, apparatuses, and computer-readable media for multiplexing channel state information (CSI) reports in scenarios involving multiple transmit-receive points (TRPs). In one aspect, a user equipment (UE) may receive at least one configuration that identifies a resource for multiplexing CSI reports that have a potential to collide in a slot. The UE may receive the at least one configuration from either, or both, of a first TRP or a second TRP. The UE may transmit at least one of a first set of CSI reports to the first TRP or a second set of CSI reports to the second TRP, multiplexed in the resource, according to the at least one configuration.

Abstract: Certain aspects of the present disclosure provide techniques for making multi-transmission configuration indicator (TCI) state data scheduling more reliable. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a first signal indicative of a plurality of demodulation reference signal (DMRS) ports. The method may also include receiving, from the BS, a second signal indicative of a first spatial state of a physical channel and a second spatial state of the physical channel. The method may also include communicating data over the second subset and not the first subset, based on which of the plurality of DMRS ports are part of the first subset and which of the plurality of DMRS ports are part of the second subset.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use one or more antenna subarrays to perform a scheduling request (SR) operation with one or more corresponding transmission reception points (TRPs) while operating in a connected discontinuous reception mode. In some implementations, the UE may receive a configuration indicating a set of its antenna subarrays and a corresponding set of the TRPs with which to perform the SR operation. Based on this configuration, the UE may transmit an SR to the set of TRPs using the set of its antenna subarrays, receive an uplink grant from at least one TRP of the set of TRPs, and transmit uplink data to the at least one TRP. Additionally or alternatively, the UE may determine the sets of antenna elements and TRPs for the SR operation autonomously and transmit an indication of this determination when transmitting the SR.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station during a physical downlink control channel (PDCCH) monitoring occasion (PMO), first downlink control information (DCI) scheduling the UE for a first physical downlink shared channel (PDSCH) resource on a first component carrier and for a second PDSCH resource on a second component carrier. The UE may receive, during the PMO, second DCI scheduling the UE for a third PDSCH resource on the second component carrier. The UE may identify a set of downlink assignment indices (DAIs) for the first DCI and the second DCI, where the first DCI has one or more DAIs whose values are based on the first DCI scheduling PDSCH resources on different component carriers. The UE may transmit feedback based on the set of DAIs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in communication with a serving base station may identify that the UE is a potential victim of interference from a neighboring base station. The UE may transmit an interference coordination message to the neighboring base station. The interference coordination message may request modification of one or more transmission parameters at the neighboring base station. The neighboring base station may modify its transmission parameters to decrease interference with the UE, and the UE may communicate with the serving base station after transmitting the interference coordination message.
