Abstract: In one aspect of the disclosure, a UE may be configured to transmit, to a base station, application ID information identifying an application at the UE; receive a first set of RRC parameters from the base station in response to transmission of the application ID information; and apply the first set of RRC parameters to an RRC configuration of the apparatus if the application is active at the apparatus. In another aspect of the disclosure, a base station may be configured to receive, from a UE, application ID information identifying an application at the UE; determine a first set of RRC parameters associated with the application being active at the UE in response to reception of the application ID information; and transmit the first set of RRC parameters to the UE for application to an RRC configuration of the UE if the application is active at the UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently reporting channel state information (CSI) with limited overhead. In one aspect, if a user equipment (UE) is configured to transmit data and CSI to a base station periodically, the UE may transmit the CSI when the UE has data to transmit to the base station. In particular, the UE may transmit data and a CSI report during a transmission opportunity if the UE has data to transmit in the transmission opportunity. Otherwise, the UE may suppress transmission of the CSI report. In another aspect, a UE may be configured to transmit CSI to a base station when downlink channel conditions change. In particular, the UE may request to report CSI to the base station when channel conditions change, and the base station may trigger the UE to report the CSI after receiving the request.

Abstract: Wireless communications systems and methods are provided for validating a physical uplink shared channel (PUSCH) occasion defined for 2-step random access channel (RACH) in case of collisions. For example, the user equipment (UE) may determine whether a collision occurs between the PUSCH occasion for the 2-step RACH and any RACH occasion assigned for either 2-step RACH or 4-step RACH after receiving the RACH configuration or updates from the network. The UE may then exclude the PUSCH occasion from the resource pool for 2-step RACH when a collision occurs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that an uplink control information (UCI) payload satisfies a threshold size condition. The UE may map the UCI payload to an uplink control sequence. The UE may transmit a physical uplink control channel (PUCCH) that include the uplink control sequence to a base station. The uplink control sequence may be representative of the UCI payload. The base station may receive the PUCCH that includes the uplink control sequence from the UE. The base station may also determine the UCI payload by associating the uplink control sequence with a corresponding sequence index of the one or more sets of uplink control sequences.

Abstract: A base station may configure a shared time and frequency resource grid for GF transmissions by one or more UEs. A UE may obtain from the base station the configuration information and transmission parameters for a GF transmission. The UE may generate a payload for the GF transmission. The UE may be configured to segment the payload into one or multiple TBs. The UE may be further configured to measure RSRP, repeat the set of TBs, and concatenate the repeated TBs into a TBG. The UE may be further configured to insert a header within each TB, which may carry the transmission parameters and resource mapping information for the TBG. The UE may be further configured to scramble the TBG by a UE-specific multiple access signature. The UE may retransmit a subset of the TBG based on HARQ feedback from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling that configures a downlink bandwidth for a broadcast channel transmission (e.g., a physical downlink control channel transmission). The UE may determine a bandwidth of the capability is less than the downlink bandwidth, and monitor search space occasions in a period to receive samples of the broadcast channel. The period and the search space occasions may be associated with a control resource set and a search space set. The UE may receive the samples in non-overlapping subbands of the bandwidth according to the bandwidth capability, and detect the broadcast channel based on the samples. The UE may additionally monitor repeated transmission occasions in the period based on detecting the broadcast channel to detect a second broadcast channel (e.g., a physical downlink shared channel).

Abstract: A connection establishment procedure such as a handover or re-establishment procedure including a 2-step random access procedure may be completed within a defined time period. The defined time period may be measured from a handover command or a determination that a user equipment (UE) has lost a connection to a base station. The defined period of time may depend on one or both of a synchronization signal block (SSB) to random access channel (RACH) association period or a SSB to RACH association pattern period. The UE may receive a handover command from a serving cell. The UE may perform a handover in response to receiving the handover command or a re-establishment procedure in response to detecting the lost connection within the defined time period. One or more base stations may reserve resources for the connection establishment procedure during the defined time period.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a configuration of a retransmission of a first message of a random access procedure based on a set of transmission configuration options transmitted by a base station. For example, the UE may retransmit the first message but may reconfigure the first message for the retransmission based on the transmission configuration options. Additionally, the UE may configure a set of transmission configuration states based on the transmission configuration options for transmitting/retransmitting the first message. In some cases, the UE may determine to switch transmission configuration states based on a trigger signaled by the base station and/or a determination by the UE. Additionally, the UE may transmit an indication of a log of state transitions performed prior to a retransmission of the first message to facilitate combining of the retransmissions at the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use easily detectable transmission parameters to infer difficult-to- detect parameters for communications with a base station. For example, the base station may provide the UE with multiple sets of transmission parameters, and the UE 115 may choose from among these sets of transmission parameters for the communications. In some cases, the UE may be configured with a reference set of transmission parameters, receive one or more transmission parameters that are different relative to the reference set of transmission parameters, and then determine to use the different transmission parameters for the communications. Additionally or alternatively, the multiple sets of transmission parameters may be specified for a certain uplink message (e.g., random access channel messages), where the UE selects the transmission parameter set based on one or more characteristics of the uplink message.
