Abstract: A user equipment (UE) (e.g., an enhanced machine type communication (EMTC) UE) may identify several narrowbands associated with eMTC protocol based on a system bandwidth of a New Radio (NR) carrier. A base station may transmit an indication of a set of valid narrowbands for eMTC (e.g., based on coexistence considerations between eMTC and NR) to the UE. The base station may further transmit a frequency hopping pattern to the UE (e.g., associated with narrowbands within the set of valid narrowbands), and transmit one or more downlink transmissions according to the frequency hopping pattern. Additionally or alternatively, a base station may identify a subcarrier offset and/or resource block offset between resources (e.g., a resource grid) used for eMTC protocol and resources used for NR. The base station may transmit a frequency alignment parameter to the UE, and the UE may align narrowbands for eMTC accordingly.

Abstract: Methods, systems, and devices for wireless communications are described. Various aspects relate to master information block (MIB) payload splitting across multiple sets of physical broadcast channel (PBCH) resources. Some aspects more specifically relate to a transmission of a first portion of a MIB via a first set of PBCH resources and a transmission of a second portion of the MIB via a second set of PBCH resources. In some examples, the first portion of the MIB may be applicable to first user equipment (UEs) that satisfy at least a first capability level and the second portion of the MIB may be applicable to second UEs that satisfy a second capability level greater than the first capability level. For example, the first portion of the MIB may be applicable to reduced and nominal capability UEs and the second portion of the MIB may be applicable to the nominal capability UEs.

Abstract: Methods, systems, and devices for wireless communication are described. In one example, an aerial user equipment (UE) may receive an indication of a priority for cell selection for aerial UEs from each cell in a set of cells and may select a cell from the set of cells based on the priority of each cell in the set of cells. In another example, an aerial UE may connect to a network available to aerial UEs and non-aerial UEs for auxiliary communications, when appropriate. In yet another example, when an aerial UE transitions to a new mission status, the aerial UE may transmit a tracking area update (TAU) if the aerial UE is connected to a cell in a tracking area that does not support the new mission status. In yet another example, a base station may page an aerial UE based on a mission status of the aerial UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a set of resources for one or more synchronization signal blocks (SSBs) associated with one or more pseudo-random sequences. The one or more pseudo-random sequences and the set of resources may be indicated by an output of a pseudo-random function (PRF) that is based on a timing parameter, a cell identifier, and a key. In some examples, the UE may monitor a set of resources within a control resource set for a downlink control channel, where the set of resources for the downlink control channel is based on an output of the PRF. The UE communicate with a network entity via a cell associated with the cell identifier based on the monitoring.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a first cell, a polar encoded signal including a master information block (MIB) associated with the first cell, the MIB including multiple information bits and a cell barring bit that indicates whether the first cell is available for cell attachment. The polar encoded signal may include a first portion and a second portion. The UE may obtain a value of the cell barring bit based on a comparison between the first portion of the polar encoded signal and the second portion of the polar encoded signal. The UE may decode the polar encoded signal if the cell barring bit indicates that the first cell is available for cell attachment, or may search for another cell if the cell barring bit indicates that the first cell is unavailable for cell attachment.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit multiple repetitions of a paging early indication (PEI) signal to a user equipment (UE) to indicate that the UE is to receive paging signaling in a paging occasion. In some cases, a PEI occasion for transmitting a PEI repetition may have a scheduling conflict. For example, a PEI occasion may collide with other downlink signaling. A UE may implement techniques to resolve scheduling conflicts or collisions for PEI repetitions. For example, the UE may be configured to receive either colliding PEI signaling or colliding downlink signaling based on priorities of the signaling. Additionally, or alternatively, PEI signaling may be shifted (e.g., delayed) until after the downlink signaling ends. In some cases, a UE may be configured with a subset of blind decoding hypotheses for PEI decoding.

A user equipment (UE) may communicate, during a first time period while a baseband of the UE is in a first baseband state, via a first set of time and frequency resources associated with unicast scheduling of the UE, where the first baseband state supports communications by the UE in accordance with a first throughput, at least a first processing timeline, or both. The UE may then receive control signaling that indicates a multicast scheduling and a second set of time and frequency resources. The UE may then communicate via the first and second set of time and frequency resources during a second time period using either the first baseband state or a second baseband state based on information included in the control signaling, where the second baseband state is associated with higher power consumption than the first baseband state.

Abstract: An optical connector has a first connection end configured to fit with a peer adapter. The electrical connector has a second connection end configured to fit with the peer adapter. The first connection end and the second connection end have a same opening direction. In addition, the first connection end may slide along a plugging direction of the peer adapter relative to the second connection end. The first connection end is configured to be connected to the peer adapter before the second connection end. The optical connector is connected to the peer adapter before the electrical connector. This ensures that a channel for transmitting an optical signal is communicated before a channel for transmitting an electrical signal is communicated, thereby avoiding fiber burning and improving security and reliability of the opto-electronic adapter during use.
