Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information that indicates a transmission parameter associated with a random access response (RAR) type; transmit a random access message associated with the RAR type; use the transmission parameter to obtain a physical downlink control channel (PDCCH) communication that schedules a physical downlink shared channel (PDSCH) communication that includes a RAR in a medium access control protocol data unit of the PDSCH communication; and obtain or refraining from obtaining the PDSCH communication based at least in part on whether the PDCCH communication is successfully obtained using the transmission parameter. Numerous other aspects are provided.

Abstract: Wireless communication devices, systems, and methods related to mechanisms to implement improved RAR decoding performance and resource utilization efficiency in a RACH procedure. A PDCCH with common search space encodes a DCI with configuration information that schedules separate PDSCHs for different UEs/UE groups. When sending a RAR message, the PDCCH includes a DCI with a configuration field to signal multiple DMRS resources with corresponding PDSCH. Each sub-field of the configuration field may include one or multiple bits. When one bit per sub-field, the bit is a flag that when asserted leads the UE to blind decode the PDSCH associated with that DMRS resource. When multiple bits, it includes a flag field as well as one or more bits that include least significant bits of a UE identifier (or group identifier). The UE locates its identifier (or group identifier), and limits decoding to that PDSCH with corresponding DMRS resource.

Abstract: Methods, systems, and devices for wireless communications are described. A base station in a wireless communications system may perform a connection procedure (e.g. radio resource control (RRC) procedure) with a user equipment (UE), during which the base station may configure the UE with logical channel prioritization (LCP) configuration for each logical channel of a set of logical channels. The LCP configuration may indicate allowable modulation coding schemes (MCSs) for each logical channel of the set of logical channels. Following the communication procedure, the UE may receive an uplink grant for transmitting data using a corresponding logical channel of the set of logical channels. The UE may identify an MCS used by the uplink grant and may transmit the data using the corresponding logical channel with the identified MCS, based on the identified MCS of the uplink grant matching an MCS of the logical channel.

Abstract: In a network configured to communicate over multiple services, each service may have one or more SR configurations. In embodiments, a processor may detects SR collision in which SR occasions for different services as defined by their corresponding configurations at least partially overlap. Based at least on the detected potential collisions, the processor may take action to resolve the collision

Abstract: Apparatus and methods for facilitating a handover of a wireless communication device on a first wireless communication network to a second wireless communication network, wherein the first and second wireless communication networks include communications protocols that are incompatible, are disclosed. The facilitation can include establishing communications between the wireless communication device and an interworking component of the second wireless communication network using a transparent tunnel through the first wireless communication network so that a message containing session information for the second wireless communication network can be exchanged. The facilitation further includes creating a profile on the second wireless communication network for a communication session between the wireless communication device and the second wireless communication network.

Abstract: Apparatus and methods are disclosed for adapting the power of an access probe transmission, in accordance with a reverse link underload indicator provided by the base station. In one example, the base station can transmit a one-bit reverse link underload indicator as an information element broadcasted within a general page message (GPM). Here, the reverse link underload indicator can indicate whether a measured rise-over-thermal (RoT) at the base station is less than a given threshold. The access terminal may accordingly reduce the initial transmit power of an access probe transmission in the case of a reverse link underload condition, as this condition would indicate that the base station could accommodate reduced power access probe transmissions without substantially decreasing the probability of a quick detection of the access attempt. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a passive Intemet of Things (IoT) traffic report that indicates a set of passive IoT communications to be performed between the UE and one or more passive IoT devices. The UE may receive a scheduling grant from a network entity in response to the passive IoT traffic report. The scheduling grant may indicate a set of time and frequency resources allocated for the set of passive IoT communications between the UE and the one or more passive IoT devices. Accordingly, the UE may perform the set of passive IoT communications with the one or more passive IoT devices using the set of time and frequency resources indicated by the scheduling grant. The techniques described herein may enable the UE to perform passive IoT communications with fewer signal collisions and lower communication resource overhead.

Abstract: New radio (NR) power headroom report (PHR) design for millimeter wave (mmWave) deployment is discussed. The power control process for mmWave may include beam-specific periodic PHR reporting and user equipment (UE)-specific event-trigger PHR reporting. The periodic PHR reporting may either provide a single PHR that includes power headroom information for each of the serving beams, or the UE may be configured to measure and report PHR for different beams in different slots. When reporting a single PHR with power headroom information for multiple serving beams, a beam index may be included in the reserved bits of the PHR. For the event-trigger PHR, the PHR reported based on a detected event trigger may provide power headroom information only for the current serving beam, or for all serving beams.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may indicate a dormancy status, such as dormant or non-dormant, for each of one or more control channel resources configured for a user equipment (UE) via a dormancy indication in downlink control information (DCI). The dormancy indication may include a set of bits, each bit indicating a dormancy status for a control channel resource or a group of control channel resources. The UE, based on determining the value of each bit of the set of bits, may determine the dormancy status of each of the one or more control channel resources and may monitor the control channel resources accordingly. For example, the UE may monitor control channel resources having a dormancy status of non-dormant and may refrain from monitoring control channel resources having a dormancy status of dormant.
