Example embodiments of the present disclosure relate to a solution for determining a set of physical random access channel (PRACH) occasions. In the solution, a first apparatus receives, from a second apparatus, configuration information indicating a plurality of PRACH occasions comprising PRACH occasions in uplink resource and PRACH occasions in sub-band non-overlapping full-duplex (SBFD) resource; determines, based on the configuration information, and for each frequency resource index for frequency multiplexed PRACH occasions, a starting PRACH occasion of a set of PRACH occasions for a PRACH transmission with preamble repetitions from the PRACH occasions in uplink resource and the PRACH occasions in SBFD resource, and performs, to the second apparatus, the PRACH transmission based at least in part on the starting PRACH occasion of the set.

Determination for uplink repetitions

Systems, methods, apparatuses, and computer program products for improved handling of cross-link interference on physical random access channel occasions on flexible or full duplexing slots are provided. For example, a method can include providing a plurality of random access channel configurations to a user equipment. A first random access channel configuration of the plurality of random access channel configurations can be for a first set of symbols or slots and a second random access channel configuration of the plurality of random access channel configurations can be for a second set of symbols or slots. The method can also include providing, to the user equipment, one or more parameters configured to steer the user equipment to select between the first set of symbols or slots or the second set of symbols or slots to be used when performing a random access transmission. The method can further include receiving a random access transmission on the selected set of symbols or slots based on one of the plurality of random access channel configurations.

Handling of cross-link interference on physical random access channel occasions on flexible/full duplexing slots

There is provided a method comprising: determining that there are no uplink resources available for transmitting a Scheduling Request; initiating a timer in response to said determination; and if said timer expires, on expiry of said timer, initiating a random access procedure on the uplink.

Random access for NR

A method is provided where a set of beams is transmitted from an access point in a first sweeping order in a first cell. The beams transmit a reference signal. A first subset of the beams is configured to be transmitted in a neighbor zone direction of the first cell, within a first common block of time as a second subset of beams being transmitted in a second cell in a neighbor zone direction. Each beam of the first and second subsets of beams are transmitted at different times in the first common block of time.

Method, system and apparatus

It is provided a method, including detecting whether or not a terminal has completed a reconfiguration of a radio bearer based on a first reconfiguration message, wherein the first reconfiguration message provides a first configuration of a first radio bearer in a first cell; detecting whether or not a cell update message is received from the terminal, wherein the cell update message indicates that the terminal has performed a cell update from the first cell to a second cell different from the first cell; triggering, if the terminal has not completed the reconfiguration and the cell update message is received, providing a second reconfiguration message to the terminal, wherein the second reconfiguration message provides a second configuration of a second radio bearer in the second cell.

RLC reconfiguration during cell reselection

A method includes receiving information at a base station for a plurality of user equipment, said information including respective data for a plurality of user equipment, said respective data to be transmitted in a same scheduling interval, and causing said respective data to be transmitted in the same scheduling interval.

Methods and apparatus

Systems and techniques for packet switched connection management. Upon a handover/cell change request with change of routing area code, an examination is made of parameters associated with a user equipment affected by the request for indications that the user equipment is engaged in a packet switched connection. Conditions associated with the handover/cell change request to determine if the packet switched connection should be released. If conditions associated with the handover/cell change request do not indicate that the packet switched connection should be released, release of the packet switched connection is inhibited.

Systems and techniques for handover control

Communication systems, such as reliant on the third generation partnership project, may benefit from a reduced number of discontinuous reception cycles needed to receive emergency messages. More specifically, such communication systems may benefit from methods and systems for sending broadcast control channel modification info such as earthquake and tsunami warning system information to user equipment in enhanced cell paging channel in one discontinuous reception cycle.
