Abstract: Methods, systems, and devices for wireless communications are described. A frame, scheduling instance, scheduling period etc. may include a set of downlink subframes and a set of uplink subframes. At least one control message transmitted in a downlink subframe may schedule a set of data messages in the downlink subframes of the frame. The downlink subframe may also include data messages scheduled by a control message of a previous frame. Further, feedback timings for data messages of the frame may be determined based on the corresponding control messages (e.g., from the current frame and the previous frame). Feedback responses corresponding to the data messages may be transmitted in a bundled manner in the set of uplink subframes. Using this cross-frame scheduling technique, the resources of a frame may be efficiently utilized.

Abstract: Some techniques and apparatuses described herein provide for the determination of a gap for a scheduled communication involving multiple, different TBs. For example, some techniques and apparatuses described herein provide for the determination of a gap between two or more PDSCHs that are scheduled by a same DCI based at least in part on a UE capability, such as a processing time or a processing mode. Some techniques and apparatuses described herein provide for the determination of a gap between a last PDSCH and a next PDCCH based at least in part on the UE capability. The gap(s) may permit the UE to successfully receive and/or decode multiple PDSCHs and/or PDCCHs in view of the limitations imposed by the UE's processing time or processing mode. In this way, efficiency of PDSCH/PDCCH resource utilization may be improved, the likelihood of a failed PDCCH transmission is reduced, and network efficiency is improved.

Abstract: A wakeup signal (WUS) group that may be divided into WUS sub-groups, criteria or metrics for dividing the WUS group into a set of WUS sub-groups, and signaling or messaging to support the division of the WUS group into the set of WUS sub-groups are provided. For example, a set of UEs may be divided into WUS sub-groups based at least in part on respective frequencies of occurrence of paging occasions for the set of UEs (e.g., based at least in part on traffic type, observations regarding past paging occasions, predictions regarding future paging occasions, and/or the like) and/or based at least in part on other considerations. Furthermore, some techniques and apparatuses described herein provide for the mapping of network device-level WUS sub-groups (e.g., supported by a network device such as an MME) to base station-level WUS sub-groups (e.g., supported by a base station).

Abstract: RESUMEN Algunas técnicas y aparatos descritos en la presente prevén la determinación de un intervalo para una comunicación programada que implica múltiples TB diferentes. Por ejemplo, algunas técnicas y aparatos descritos en la presente prevén la determinación de un intervalo entre dos o más PDSCH que se programan mediante una misma DCI con base, al menos en parte, en una capacidad de UE, tal como un tiempo de procesamiento o un modo de procesamiento. Algunas técnicas y aparatos descritos en la presente prevén la determinación de un intervalo entre un último PDSCH y un próximo PDCCH con base, al menos en parte, en la capacidad de UE. Los intervalos pueden permitir que el UE reciba y/o decodifique con éxito múltiples PDSCH y/o PDCCH considerando las limitaciones impuestas por el tiempo de procesamiento o modo de procesamiento del UE. De este modo, la eficacia del uso de recursos de PDSCH/PDCCH puede mejorarse, la probabilidad de una transmisión de PDCCH fallida se reduce, y la eficacia de la red se mejora.

Abstract: Various aspects described herein relate to techniques for frequency hopping for a wideband allocation in wireless communications. A wideband allocation of resources for transmitting uplink wireless communications can be determined, as well as a frequency hopping offset related to one or more narrowbands for transmitting uplink wireless communications. In addition, it can be determined whether to apply the frequency hopping offset to the wideband allocation in communicating data. The data can be communicated over resources related to the wideband allocation with the frequency hopping offset applied communicating, based on determining to apply the frequency hopping offset.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may transmit, and an enhanced machine-type communications (eMTC) user equipment (UE) may receive, an indicator indicating use of a control region of a carrier for a downlink transmission. The BS may transmit and the eMTC UE may receive, based at least in part on the indicator, the downlink transmission during the control region of the carrier. Numerous other aspects are provided.

Abstract: Aspects directed towards wake-up signal (WUS) scrambling sequence design are disclosed. In one example, a time-based scrambling sequence that facilitates a phase shift in time may be generated according to a time parameter associated with a WUS or a paging occasion (PO). A scrambled WUS may be generated by multiplying a WUS base sequence by the time-based scrambling sequence, and subsequently transmitted to at least one scheduled entity. In another example, a scrambled WUS may be received from a scheduling entity. A time-based scrambling sequence associated with the WUS may be identified in which the time-based scrambling sequence facilitates a phase shift in time and corresponds to a time parameter associated with a WUS or a PO. The WUS may be descrambled according to the time-based scrambling sequence. Other aspects, embodiments, and features are also included.

Abstract: Aspects directed towards sounding reference signal (SRS) antenna switching are disclosed. In one example, an SRS configuration is received from a network in which at least four antennas of a scheduled entity are configured based on the SRS configuration. Here, the SRS configuration configures at least one antenna to simultaneously support SRS antenna switching and an uplink (UL) multiple-input multiple-output (MIMO) communication. An SRS communication is then transmitted according to the SRS configuration. In another example, a transmission capability reporting is received from a scheduled entity comprising at least four antennas. A determination is then made of whether the scheduled entity may simultaneously support SRS antenna switching and an UL MIMO communication. An SRS configuration is then generated for the scheduled entity based on the determination in which a default SRS configuration configures at least one antenna to simultaneously support the SRS antenna switching and the UL MIMO communication.

Abstract: Some techniques and apparatuses, described herein, provide for resource allocation to achieve frequency diversity, time diversity, and/or spatial diversity for wakeup signals destined to two or more UE groups by transmitting the wakeup signals according to respective resource patterns associated with the two or more UE groups. Additionally, some techniques and apparatuses described herein provide for resource allocation to achieve spatial diversity for wakeup signals for a single UE group by transmitting the wakeup signals using two or more antenna ports according to respective resource patterns associated with the two or more antenna ports. Furthermore, some techniques and apparatuses described herein provide configurations for wakeup signals based at least in part on delays or gaps, repetitious communications, synchronization in accordance with a power level of the wakeup signal, and the like.

Abstract: A method, an apparatus, a base station, a user equipment (UE), and a computer program product for wireless communication are provided. The base station may encode a wakeup signal so that a preamble of the wakeup signal indicates whether the wakeup signal is relevant to the UE. The UE may select a technique for detecting the wakeup signal based at least in part on a partial, full, or no synchronization. In some aspects, the wakeup signal may be encoded with a system frame number. In some aspects, wakeup signals for guardband/standalone UEs are provided. Numerous other aspects are provided.
