Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of enhancing a report for random access channel (RACH). The method comprises in accordance with a determination that a random access attempt in a random access process for accessing a second device based on configuration information is performed, determining an entry for recording the random access attempt, the entry at least comprising fallback information indicating whether a change associated with the random access attempt has occurred; generating a report for the random access process at least based on the entry; and causing the report to be transmitted to the second device. In this way, with the UE RACH report, the network device may achieve a targeted optimization for the configuration for RA process, which may improve the efficiency of the RA process and decrease the cost due to a multiple of fallback.

Abstract: Systems, methods, apparatuses, and computer program products for enabling access for a reduced capability new radio (NR) device. For example, a network may indicate which of the configured random access channel (RACH) resources can be used to perform a random access procedure within a reduced uplink (UL) bandwidth (BW) (compared to the whole initial UL bandwidth part (BWP) BW). The network may schedule any UL transmissions (e.g., Msg3 (re-)transmissions, etc.) pertaining to such random access procedure within the reduced UL BW.

Abstract: Embodiments of the present disclosure relate to contention resolution in random access procedure. A first device transmits to a second device a random access request comprising a first identification of the first device. The first device receives a response to the random access request from the second device. The response comprises a second identification from the second device for the first device and control information indicating a resource for communication between the first device and the second device. The first device compares the second identification with the first identification to determine data to be transmitted by using the indicated resource.

Abstract: A method includes determining whether a downlink beam signal is being received from a base station (502); when the downlink beam signal is being received from the base station, determining whether a measurable property of the downlink beam signal does not meet a preselected threshold (504); when the downlink beam signal is not being received from the base station or when the measurable property of the downlink beam signal does not meet the preselected threshold, transmitting a message to the base station indicating that at least one uplink beam corresponding to the downlink beam has failed (506); and receiving a reply message from the base station with information required to determine a new uplink beam (508). An alternative method includes determining whether at least one uplink beam signal is being received from a user equipment (602); determining whether a measurable property of the at least one uplink beam signal does not meet a preselected threshold, when the at least one uplink beam signal is being received from the user equipment (604); and transmitting a message to the user equipment to initiate uplink beam recovery, when at least one uplink beam signal is not being received from the user equipment or when the measurable property of the at least one uplink beam signal does not meet the preselected threshold (606).

Abstract: Method, apparatuses, and computer program product for addressing random access responses with extended response windows. One method may include accessing, by a user equipment, a network by sending a random access channel preamble to a network element. The method may also include receiving, in response to the random access channel preamble, a random access response from the network element. The random access response provides an indication of which random access channel occasion in time within a span of one or a plurality of radio frames the random access response applies.

Abstract: Embodiments of the present disclosure relate to reporting beam failure. A terminal device detects a beam failure on one or more serving cells of the terminal device. If the beam failure is detected on the one or more serving cells, the terminal device obtains information concerning one or more candidate beams and the one or more serving cells. Each of the one or more candidate beams is associated with a respective one of the one or more serving cells. The terminal device then transmits at least a portion of the information to a network device associated with the one or more serving cells.

Abstract: Embodiments of the present disclosure relate to recording of failure cancellation. The first device detects a cancellation of a reporting of a failure for a transmission between the first device and a second device. Then, in accordance with a determination that the cancellation of the reporting of the failure is detected, the first device records information concerning the cancellation. As such, the first device is able to provide the recorded information on failure cancellation to the second device when needed.
