Abstract: Methods, systems, and devices for wireless communications are described. A rateless code may be used to generate n encoded packets based on a set of source packets. A modulation technique may be used to generate first symbol packets from the encoded packets. And a layered modulation technique may be used to generate coded symbol packets from the first symbol packets. The layered modulation technique may include generating a coded symbol packet from a group of first symbol packets. Different weights may be applied to the different first symbol packets included in the group of first symbol packets before the first symbol packets in the group are combined together. A receiving device may demodulate the transmitted coded symbol packets to reconstruct the group of first symbol packets, use the reconstructed group of first symbol packets to recover the encoded packets, and use the encoded packets to reconstruct the source packets.

Abstract: In an aspect, a wireless node (e.g., UE or BS) measures, at a first hop of a frequency hopping scheme, a reference signal (RS) on a first sub-band of an effective RS bandwidth, and measures, at a second hop of the frequency hopping scheme, the RS on a second sub-band of the effective RS bandwidth, the first and second sub-bands of the effective RS bandwidth overlapping in part. In another aspect, a UE transmits, at a first hop of a frequency hopping scheme, a reference signal (RS) on a first sub-band of an effective RS bandwidth, and transmits, at a second hop of the frequency hopping scheme, the RS on a second sub-band of the effective RS bandwidth, the first and second sub-bands of the effective RS bandwidth overlapping in part.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a first beam failure recovery (BFR) has been triggered; determine BFR information associated with the BFR; determine whether at least part of the BFR information has not been transmitted since a second BFR was triggered; and transmit, based at least in part on the determination that the BFR has been triggered and the determination that at least part of the BFR information as not been transmitted since a second BFR was triggered, a BFR message including the BFR information. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a report for one or more two-step random access channel (RACH) procedures between the UE and a base station (BS), wherein the RACH report includes at least one of an indication of a quantity of message A (MsgA) payloads transmitted during the one or more two-step RACH procedures on each beam of one or more beams associated with the BS, an indication of one or more parameters associated with each MsgA communication transmitted during the one or more two-step RACH procedures, or an indication of whether a respective signal strength for each beam, associated with the one or more two-step RACH procedures, satisfies a signal strength threshold. The UE may transmit the report to the BS. Numerous other aspects are provided.

Abstract: Aspects described herein relate to transmitting an indication of a capability to support concurrent or time division multiplexed uplink transmission of at least one of multiple uplink channels across multiple component carriers. In addition, a configuration to transmit over the at least one of the multiple uplink channels over the multiple component carriers using concurrent transmission or time division multiplexed transmission can be received based on the indication.

Abstract: Aspects described herein relate to requesting suspending of a data session of a first when a device capable of communicating over multiple subscriptions switches from an active communication state if the first network to an active communication state in a second network. The device can also request resuming the data session based on switching back to active communication state with the first network.

Abstract: This disclosure relates to methods, devices, and systems for wireless communications, and more particularly to aggregating physical uplink shared channel (PUSCH) resource units relating to a random access message. A user equipment (UE) may identify a random access message of a random access procedure. The random access message may include a random access preamble and a random access payload. The UE may aggregate multiple PUSCH resource units of a set of PUSCH resource units associated with one or more PUSCH occasions (POs) based on one or more of a payload size of the random access payload or a modulation and coding scheme associated with the random access payload. As a result, the UE may transmit the random access payload of the random access message on a PUSCH using time and frequency resources of the aggregated multiple PUSCH resource units over the one or more POs.

Abstract: In an embodiment, a base station determines a spatial relationship for a group of PUCCH resources, and transmits a control message that indicates the spatial relationship to a UE. The UE receives the control message and stores an indication of the spatial relationship. In some designs, the control message conveying the spatial relationship identifies the group of PUCCH resources via the PUCCH group index, while in other designs a different identification mechanism may be used. In another embodiment, a base station determines an association between a group of PUCCH resources and a PUCCH group index, and transmits a control message that indicates the association to a UE. The UE receives the control message and stores an indication of the association.
