Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may configure a UE to transmit a cross link interference reference signal (CLI-RS) using a bandwidth and frequency similar to those used for a synchronization signal. In another aspect, a BS may may configure a UE to measure a cross link interference reference signal (CLI-RS) transmitted using a bandwidth and frequency similar to those used for a synchronization signal. In other aspects, a base station may transmit, to a UE, an instruction to transmit or measure a CLI-RS. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. In some cases, due to blind decoding and channel estimation (CE) limits, one or more user equipment (UE) specific search sets may be pruned for blind decoding and/or CE purposes. For instance, after hashing a set of common decoding candidates to control channel elements (CCEs) within the control region, the UE specific search sets may be pruned so as to conform to the blind decode limitation, since a common search space has already occupied a portion of the total blind decode limit. Following pruning, the UE may hash the sets of UE-specific decoding candidates associated with the one or more UE specific search sets to CCEs within the control region. The UE may further prune UE specific search sets, based on CE limits, while reusing CE for overlapping hashed locations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive from a base station a measurement configuration signal comprising a measurement resource configuration associated with a cross-link interference signal strength measurement. The UE may perform the cross-link interference signal strength measurement for one or more UEs associated with one or more intra-frequency neighboring cells according to the measurement resource configuration, wherein the cross-link interference signal strength measurement is performed during an intra-frequency measurement gap. The UE may transmit a report of the cross-link interference signal strength measurement to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling that configures a downlink bandwidth for a broadcast channel transmission (e.g., a physical downlink control channel transmission). The UE may determine a bandwidth of the capability is less than the downlink bandwidth, and monitor search space occasions in a period to receive samples of the broadcast channel. The period and the search space occasions may be associated with a control resource set and a search space set. The UE may receive the samples in non-overlapping subbands of the bandwidth according to the bandwidth capability, and detect the broadcast channel based on the samples. The UE may additionally monitor repeated transmission occasions in the period based on detecting the broadcast channel to detect a second broadcast channel (e.g., a physical downlink shared channel).

Abstract: Various designs for reference signals for beam management (BM) in non-terrestrial networks (NTNs) in 5G systems are discussed. NTN platforms determine to transmit a BM reference signal associated with a beam in an NTN. The BM reference signal is configured to facilitate beam switching at a wireless communication entity, and the beam having a beam bandwidth. The NTN platforms determines a frequency resource for transmitting the BM reference signal, and transmits, to a wireless communication entity, the BM reference signal in the determined frequency resource. The wireless communication entity monitors the frequency resource, receives the BM reference signal associated with the beam in the frequency resource, and manages beam selection based on the received BM reference signal. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A base station and a user terminal may communicate via a relaying satellite in a non-terrestrial network. The non-terrestrial network may cause communication disruptions in hybrid automatic repeat request (HARQ) processes due to communication delays. Base stations and user terminals communicating via a satellite may implement dynamically configurable HARQ processes to avoid latency in a wireless communications system.

Abstract: Methods, systems, and devices for wireless communication are described that may enable a user equipment (UE) to monitor a shared spectrum to receive control signaling and data transmissions associated with different transmission time intervals (TTIs). For example, a base station may communicate with a UE according to a first transmission mode during a first, shortened TTI. The base station may transmit a downlink control channel for a shortened TTI based on a subset of a number of blind decodes or control channel elements. Additionally, a downlink control channel for a shortened TTI may contain grants for multiple TTIs. In some cases, the base station may transmit a signaling to the UE via a reference signal, downlink control channel, or radio resource control which may indicate a change from the shortened-TTI transmission mode to a transmission mode with a TTI duration that is longer than the first, shortened TTI duration.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may implement cross-carrier scheduling. A user equipment (UE) may identify a minimum scheduling delay and may receive a downlink grant on a first CC. The UE may further identify the slot in which a downlink data transmission corresponding to the downlink grant will be received, and may identify the slot such that the minimum scheduling delay is satisfied. The UE may the receive the downlink data transmission, as indicated in the downlink grant, in the identified slot. In some examples, the UE and the base station may alternate between a long minimum scheduling delay and a short minimum scheduling delay. In some examples, the UE and the base station may alternate between a cross-carrier mode, and a self-scheduling mode.
