Patent number: 11445436Abstract: Various communication systems may benefit from improved cell selection. For example, it may be helpful to improve cell selection in new radio systems based on individual synchronization signal blocks meeting specific thresholds. A method may include measuring at a user equipment a cell quality of one or more cells. The method may also include detecting at the user equipment synchronization signal blocks in the one or more cells. In addition, the method may include determining at the user equipment that the synchronization signal blocks do not meet a random access channel resource selection threshold. Further, the method may include selecting at the user equipment only random access channel resources that correspond to the synchronization signal blocks meeting a cell selection threshold.Type: GrantFiled: August 29, 2018Date of Patent: September 13, 2022Assignees: NOKIA OF AMERICA CORPORATION, NOKIA TECHNOLOGIES OYInventors: Sami Hakola, Jorma Kaikkonen, Emad Farag

Publication number: 20220124816Abstract: A technique of performing a RACK procedure includes a framework for a two-step RACK in which a first message (MsgA) from the UE to the gNB has data carrying resources (i.e., PUSCH) is organized into a time-frequency array defined by a mapping to a plurality of preambles. Such a two-step RACK has less latency than the four-step RACK due to fewer signaling exchanges. Moreover, this two-step RACK also causes the UE to use less power due to a decreased signaling overhead.Type: ApplicationFiled: February 11, 2020Publication date: April 21, 2022Inventors: Emad Farag, Frank Frederiksen, Nuno Manuel Kiilerich Pratas

Publication number: 20220070941Abstract: Fallback aspects associated with the power ramping procedure are addressed. More specifically, a set of control mechanisms allows for a gNB to adjust thresholds for controlling the UE transfer from a 2-step RACH procedure to a 4-step RACH procedure while still maintaining a proper setting for transmit power during this transition. The mechanism will allow for a UE to have a smooth transition to the 4-stepprocedure instead of having to start the power ramping from scratch when transferring to the fall-back routine.Type: ApplicationFiled: February 11, 2020Publication date: March 3, 2022Inventors: Emad FARAG, Frank Frederiksen, Nuno Manuel Kiilerich Pratas

Publication number: 20180324852Abstract: A user equipment (UE) selects first and second radio resources from respective first and second pools of radio resources. In one example these are primarily allocated for contention-free and scheduling-based channel access, respectively. Content to duplicate in parallel communications is selected based at least on a characteristic of uplink data waiting to be sent (such as size) and/or on the selected first and second radio resources (such as timing difference between them). The UE transmits the selected content on each of the selected first and second radio resources. In the examples the content to duplicate was selected from among the uplink data to send and a scheduling request message. In various embodiments one of these transmissions indicates it's a duplicate, and the duplicated scheduling request message is transmitted on the first resource with the uplink data. These teachings are particularly useful for URLLC data.Type: ApplicationFiled: May 4, 2017Publication date: November 8, 2018Inventors: Vinh Van Phan, Ling Yu, Zexian Li, Bikramjit Singh, Mikko Aleksi Uusitalo, Emad Farag
