Abstract: A method of wireless communication by a user equipment (UE) calculates a propagation delay for sending a message from the UE to a network node, such as a base station, via non-terrestrial communications. The method sends a random access preamble to the base station while accounting for the calculated propagation delay. The method starts a random access response (RAR) window at a first physical downlink control channel (PDCCH) occasion after twice the calculated propagation delay from sending the random access preamble. The method receives a random access response (RAR) message from the base station during the RAR window. The RAR message includes an uplink grant indicating an uplink shared channel resource. Further, the method sends an uplink message to arrive during the uplink shared channel resource while accounting for the calculated propagation delay.

Abstract: Aspects described herein relate to indicating search spaces and/or control information formats for receiving multicast/broadcast service (MBS) downlink control information (DCI). A device can receive a search space configuration defining one or more search spaces for detecting communications intended for a group of one or more user equipment (UEs), determine a priority for detecting control information transmitted over a control channel based on the one or more search spaces, and perform, based on the priority, detection for the control information over the control channel based on the one or more search spaces and/or the other defined search spaces.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a notification of a change to multicast broadcast (MB) control information associated with at least one MB service to which the UE is subscribed, the MB control information being included in an MB control channel (MBCCH) scheduled by a physical downlink control channel (PDCCH) communication addressed to an MB radio network temporary identifier (MB-RNTI); and monitor one or more resources of the MBCCH to receive updated MB control information based at least in part on receiving the notification of the change to the MB control information. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a medium access control (MAC) control element (MAC CE) including a command to alter a configuration of the UE; identify a time to alter the configuration of the UE based at least in part on at least one of a relative time indicator, an absolute time indicator, a triggering event, or a type of the MAC CE; and implement, at the time identified for altering the configuration of the UE, the command of the MAC CE to alter the configuration of the UE. Numerous other aspects are provided.

Abstract: In an example, a method of wireless communication of a base station may include assigning, by the base station, one or more resources to a group comprising a plurality of UEs that includes a first UE. The method may include receiving, by the base station from the first UE, a message on the one or more assigned resources. The message may include a cyclic redundancy check (CRC) scrambled with a group identifier for the group comprising the plurality of UEs. The message may include an indication of a UE identifier for the first UE within the group. The message may include a DMRS, where the indication of the UE identifier is represented by a sequence of the DMRS.

Abstract: Aspects encompassing public land mobile network (PLMN) configurations are disclosed. In one example, first and second PLMN configurations are determined, and a parameter having a common identifier between a hybrid PLMN and a PLMN from a different PLMN configuration is identified, such that the hybrid PLMN may connect with a first or second core network type. Inclusion of the common identifier is limited to either the first or second PLMN configuration via an index, and the first and second PLMN configurations are transmitted. In another example, first and second PLMN configurations are received, and a hybrid PLMN in one of the two PLMN configurations is selected. A determination is made whether to use the hybrid PLMN to connect with a first or second core network type. Whether a hybrid PLMN parameter was ascertained via the first or second PLMN configuration is reported. Other aspects, embodiments, and features are also included.

Abstract: Various features presented herein facilitate early data transmission (EDT) in eMTC and NB-IoT. In certain aspects, a UE (e.g., an eMTC and/or NB-IoT type device), may receive an indication in a SIB from a base station that may enable EDT by the UE. The UE may transmit a random access request based on the SIB. The UE may further receive an MCS index in an RAR, and transmit a connection request (e.g., Msg3) to the base station based on the MCS index and the indication in the SIB. Some aspects described herein relate to an improved rate matching technique. In certain aspects, a UE may be configured to transmit a connection request message to a base station based on at least one of an increased number of RVs than a number of RVs for other transmissions from the UE or rate matching performed across more than one subframe.

Abstract: In an example, a method of communication of a UE may include establishing, by the UE, a connection with a base station. The method may include sending, by the UE to the base station, UE capability information in response to a trigger. The UE capability information may be based on whether one or more capabilities of the UE differs or is the same between a first coverage mode and a second coverage mode. In another example, a method of communication of a UE may include establishing, by the UE, a connection with a base station. The method may include sending, to the base station, first UE capability information in response to a first trigger. The method may include sending, by the UE to the base station, second UE capability information in response to a second trigger. The second UE capability information may be different from the first UE capability information.
