Abstract: Various aspects of the present disclosure generally relate to wireless communication in a shared spectrum. In some aspects, a user equipment may receive an indication of a set of starting offsets for an uplink communication, wherein the set of starting offsets includes at least one negative starting offset relative to a start of a slot or a mini-slot in which the uplink communication is configured to start; select a starting offset from the set of starting offsets; and transmit the uplink communication, wherein the uplink communication starts at a time indicated by the selected starting offset. Numerous other aspects are provided.

Abstract: Various aspects of the disclosure relate to power control for independent links. For example, power control at a device may be based on transmissions on multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, power control for the first device may be based on power control commands received on multiple links. In some scenarios, a power control constraint may be met taking into account the transmission power on multiple links.

Abstract: This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a multi-transmit-receive point (TRP) approach for hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback using counter downlink assignment indicators (DAIs) (cDAIs) and total DAIs (tDAIs) is provided. For example, some techniques and apparatuses described herein may provide a joint counting method in which cDAIs and tDAIs are implemented and tracked jointly between the TRPs of a multi-TRP group. This may be useful in the ideal backhaul scenario when the multi-TRP group is jointly scheduled, and may be more robust against errors than a separate counting method. Some techniques and apparatuses described herein may provide a separate counting method, in which cDAIs and tDAIs are implemented and tracked separately by the respective TRPs of a multi-TRP group.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, via a control channel, an order message instructing the UE to perform a random access channel (RACH) procedure, and selecting to perform a first RACH procedure or a second RACH procedure based on a preamble preparation time gap between the order message and a first occasion for transmitting a RACH preamble, or a payload preparation time gap between the order message and an occasion for transmitting a RACH payload, or both.

Abstract: Methods, systems, and devices for wireless communication are described. Different transmission time interval (TTI) durations may be supported and configured to coexist with one another. A set of TTIs with a relatively short duration may overlap in time with longer duration TTIs. Boundaries of TTIs with a relatively short duration may be configured to align with boundaries of relatively longer duration TTIs. For example, TTIs that are a Long Term Evolution (LTE) subframe, an LTE slot, and a duration of two LTE symbol periods may be supported. Two-symbol period TTIs may align with or be embedded within slot-duration TTIs, which, in turn, may align with or be embedded within a subframe. In some examples, one or more symbol periods of a subframe may be designated as a gap between two-symbol TTIs within the subframe, or such symbols may be merged with a two-symbol TTI within the subframe.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit receive point in a multi-TRP configuration, a downlink control information (DCI) communication. The UE may identify one or more quasi-co-location (QCL) relationships associated with a control resource set (CORESET) or a search space set in which the DCI communication is received. A QCL relationship, of the one or more QCL relationships, is associated with one or more physical downlink shared channel (PDSCH) layers that are transmitted from a second TRP in the multi-TRP configuration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use information received as part of a two-step random access channel (RACH) procedure to indicate that the two-step RACH procedure has been completed. For example, a UE may perform a two-step RACH procedure that includes the UE transmitting a first message to a base station and, in response, receiving a second message from a base station. The second message may include feedback information the UE uses to signal that the RACH procedure has been completed. In some examples, the feedback information may indicate a physical channel or grant, or both, and a third message may be transmitted by the UE based on the feedback information included in the second message. As such, the third message may serve as an indication that the second message was received, and the UE completed the RACH procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first downlink control information (DCI) communication for scheduling a first physical downlink shared channel (PDSCH). The first PDSCH may be associated with at least a first transmit receive point (TRP). The UE may receive a second DCI communication for scheduling a second PDSCH. The second PDSCH may be associated with a second TRP and at least one of the first TRP or a third TRP. The UE may receive downlink communications based at least in part on the first DCI communication and the second DCI communication. Numerous other aspects are provided.

Abstract: In order to overcome problems that a UE may face in determining CORESETs and beams for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL relationships, UL resources, and/or spatial relationships are selected for a COT. A UE receives an indication of a set of CORESETs selected from a plurality of CORESETs or a set of QCL relationships selected from a plurality of QCL relationships. The UE determines the set of CORESETs from the plurality of CORESETs or the set of QCL relationships from the plurality of QCL relationships based on the indication received. A UE receives an indication of a set of UL resources or a set of spatial relations. The UE determines the set of UL resources or the set of spatial relations based on the indication received.
