Common channel configuration in new radio inactive state

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a radio resource control (RRC) resume message, associated with transitioning the UE from an inactive state to a connected state. The UE may configure, based at least in part on receiving the RRC resume message, the UE with a serving cell common configuration, associated with a serving cell of the UE, received in a system information block (SIB) associated with the serving cell. Numerous other aspects are provided.

Method and apparatus for determining a user data resource assignment

A method and apparatus can determine a user data resource assignment in a wireless network. A control channel candidate can be monitored for a control channel. The control channel candidate can correspond to a CCE parameter that is a function of a first RBG size used for user data resource assignments. The control channel can be decoded. A user data resource assignment can be determined based on the decoded control channel. The user data resource assignment can be based on a second RBG size.

Terminal apparatus, base station apparatus, communication method, and integrated circuit

A terminal apparatus transmits one random access preamble in multiple time sections, and changes a transmit beam to be used to transmit the one random access preamble in one of the multiple time sections or each of the multiple time sections, and monitors a random access response to the one random access preamble. The random access response includes first information for identifying any one of the multiple time sections.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, from a base station, a broadcast message comprising a first set of random access parameters for a first uplink band supported by the base station and a second set of random access parameters associated with a second uplink band supported by the base station. The UE may select one of the first set of random access parameters or the second set of random access parameters for a random access signal. The UE may transmit a random access signal over one of the first uplink band or the second uplink band using the selected one of the first set of random access parameters or the second set of random access parameters.

Reuse of transmission resources for device to device communication

The present invention provides a method of determining a transmission power for device to device, D2D, transmissions between a first user equipment device and a second user equipment device using transmission resources being used for transmissions to a cellular network entity by a third user equipment device, the method comprising determining a measure of a path loss between the cellular network entity and the first user equipment device, and using the measure of the path loss to determine a maximum transmission power such that the D2D transmissions are received at the cellular network entity with a signal level around or below a noise level.

Registration method, session establishment method, terminal, and AMF entity

A registration method, a session establishment method, a terminal, and an access and mobility management function (AMF) entity, where the method includes: sending, by a terminal, a first message to the AMF entity, where the first message includes first information, first network slice selection information, and second network slice selection information, the first information includes information for requesting to establish a protocol data unit (PDU) session, the first network slice selection information is used by the AMF entity to select a first session management function (SMF) entity, and the second network slice selection information is used by the AMF entity to select a second SMF entity; and receiving, by the terminal, a second message from the AMF entity, where the second message includes second information, and the second information includes PDU session establishment accept information.

Message Mapping via Frequency and/or Time Indexing
20220386415 · 2022-12-01 ·

This disclosure relates to techniques for supporting message mapping via time and/or frequency indexing. For example, these techniques may be applied to device-to-device wireless communication. For example, device to device discovery may use message mapping via frequency indexing. A portion of the payload of a message, such as a discovery message, may be offloaded to a frequency and/or time index. A receiving device may determine the offloaded portion of the payload based on the frequency and/or time (e.g., subcarrier and/or slot) used to transmit the message.

Radio communication system and radio base station

A user equipment is disclosed including a receiver that receives an RRC message related to configuration information of a second radio base station for a split hearer that splits from the second radio base station toward a first radio base station, and a processor that releases resources related to a radio link of the second radio base station based on the RRC message when a radio link failure in the second radio base station is detected.

Enhancements on random access for NR-unlicensed

A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of a physical random access channel (PRACH) over physical resource blocks (PRBs) that are interlaced in an unlicensed band in an NR unlicensed (NR-U) communication. The PRBs in the PRACH can be based on an occupied channel bandwidth (OCB) of the unlicensed band in the NR-U communication. A random access channel transmission in the PRACH can then be generated by interlacing the PRBs defining the PRACH.

Method and device for updating user devices via a cellular connection

A device obtains a data structure from a computing device, and divides the data structure into data segments. The device obtains a list of user devices from the computing device and obtains, from one or more network devices, a respective location and a respective reachability of each user device. The device determines, based on the respective location of each user device, a set of user devices connected to a base station. The device determines a communication capability of the base station, and determines, based on the communication capability, a subset of the set of user devices and one or more sets of the data segments. The device sends, based on the respective reachability of each user device of the subset of user devices, the one or more sets of data segments to the subset of user devices via the base station.
