Abstract: A method of wireless communications by a user equipment (UE) includes transmitting a wakeup message to awaken a base station from a sleep mode. The method also includes communicating with the base station after the base station awakens. A method of wireless communications by a base station includes entering a sleep mode when no user equipments (UEs) are connected to the base station. The method also includes receiving a signal from a UE to awaken from the sleep mode. The method further includes resuming signal transmissions after waking up from the sleep mode.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for signaling mechanisms associated with transmission puncturing schemes for rateless coding. In some aspects, a transmitting device may encode a message using a rateless code associated with a cumulative encoding of various portions of the message and may perform transmission puncturing to adapt a bit rate of related signal transmissions. The transmitting device may signal an indication of the transmission puncturing scheme, and potentially one or more modifications to the transmission puncturing scheme, to a receiving device via control signaling. The transmitting device may modify the transmission puncturing scheme in accordance with prioritizing retransmissions for some cumulative portions of the message ahead of other cumulative portions, such as by granting prioritized cumulative portions of the message relatively earlier transmission occasions in the transmission puncturing scheme.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may monitor sets of decoding candidates over a search space in each monitoring occasion to detect downlink control transmissions. Such a monitoring process may be resource intensive. To reduce the processing power involved in monitoring the control channel, a UE may measure resources associated with the downlink control channel to obtain a quality metric. The UE may compare the quality metric to one or more thresholds and may perform a decoding process on a set of configured decoding candidates for the downlink control channel based on the comparing. In some cases, if the channel quality is relatively good, the UE may perform a list decoding process using a list size less than a maximum list size or may perform partial data tone processing to reduce the processing complexity for some of the decoding candidates.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for early termination of decoding attempts, including decoding attempts associated with physical downlink control channel (PDCCH) candidates that are encoded using a rateless code. In some aspects, a transmitting device may encode a message using a rateless code associated with a cumulative encoding of various portions of the message, and using a device identifier or group identifier as an input to the encoding. Similarly, a receiving device may receive an encoded signal over candidate resources and may attempt to decode the signal in accordance with the rateless code and using a device identifier or a group identifier as an input to the decoding. As such, intended or non-intended receiving device may be able to evaluate whether to proceed with a decoding attempt or to terminate a decoding attempt at a relatively early stage.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a first wireless device. The first wireless device may participate in a beam forming procedure with a second wireless device to evaluate a plurality of transmit (TX) and receive (RX) beam pairs. The first wireless device may select one of the TX and RX beam pairs based on the evaluation. The first wireless device may determine at least one cryptographic key based on channel parameters associated with a selected one of the TX and RX beam pairs. The first wireless device may use the at least one cryptographic key for communications with the second wireless device.

Abstract: User equipment (UE) may benefit from power management techniques, for example, in the context of cellular vehicle-to-everything (CV2X) communication. In various aspects of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to determine whether a first subframe includes at least one sub-channel carrying information intended for the UE, receive the information via at least one receive (Rx) chain associated with the at least one sub-channel when the information intended for the UE is carried on the at least one sub-channel included in the first subframe, and deactivate the at least one Rx chain associated with the at least one sub-channel based on whether the information intended for the UE is absent from the at least one sub-channel included in the first subframe.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a first device may combine, for each of a set of sub-blocks of a block of data, a set of unencoded bits associated with a respective sub-block with a matrix to generate a set of encoded bits. The first device may transmit a first message including the block to a second device. The second device may determine respective probabilities of successful decoding of respective selected candidate codewords for the set of sub-blocks of the block based on receiving the first message and may transmit one or more indicators associated with one or more sub-blocks based on the respective probabilities of successful decoding of the respective selected candidate codewords. The first device may transmit a second message including redundancy information for the one or more sub-blocks based on transmitting the one or more indicators.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater may receive, via a first frequency band, a first one or more signals of a communication that is associated with a multiple hop link, wherein the first one or more signals are associated with a first one or more communication parameters that result in a data capacity for the first one or more signals. The repeater may perform an action to adjust the first one or more communication parameters to a second one or more communication parameters for transmission via a second frequency band, the second one or more communication parameters causing the data capacity to be maintained. The repeater may transmit, via the second frequency band, a second one or more signals of the communication using the second one or more communication parameters. Numerous other aspects are described.
