摘要： A method for adaptively optimizing a random access response (RAR) message by a radio access network (RAN) node includes: determining a first number of connection attempts over a first time duration that are received from one or more user equipment (UE); determining a success rate for the first number of connection attempts; updating one or more parameters to adjust a code rate used for generating communication messages to the one or more UEs, from a first code rate to a second code rate, based at least in part on the success rate; generating the RAR message using the second code rate, in response to receiving an initial access connection request message from a first UE among the one or more UEs; sending the RAR message based at least in part on the second code rate to the first UE.

摘要： A method is provided. The method includes receiving, by a new radio (NR) base station (gNB) from a user equipment (UE), an access request on an initial beam of a plurality of beams transmitted by the gNB, the initial beam being determined by the UE as an optimal access request beam, transmitting, by the gNB to the UE, a response to the access request on the initial beam, receiving, by the gNB from the UE, an indication of a first optimal beam to use for data transmission from the gNB to the UE, switching, by the gNB, data transmission from the initial beam to the first optimal beam based on the first optimal beam being different from the initial beam.

摘要： A method is provided. The method includes determining, while a user equipment (UE) is connected to a long term evolution (LTE) cell, that the UE supports connection with a first fifth generation (5G) frequency range (FR1) base station (gNB) and a second 5G frequency range (FR2) base station (SgNB), when the UE is camped to an FR1 cell, determining whether at least one connection condition is satisfied, and controlling to release the UE from the FR1 cell and initiating the UE to an FR2 cell when the at least one connection condition is determined to be satisfied.

摘要： An apparatus and method for optimizing an aggregation level for communicating physical downlink shared channel (PDSCH) resources in a random access network (RAN) are provided. The apparatus includes a memory storing instructions; and at least one processor configured to execute the instructions to: receive, by a radio access network (RAN) node, a random access request message from a user equipment (UE); determine, by the RAN node, a signal-to-interference-plus-noise ratio (SINR) of the first random access request message; compare the SINR with a first predetermined threshold; based on the comparing, determining an aggregation level from among a plurality of predetermined aggregation levels; and transmit a random access response message from the RAN node to the UE based on the determined aggregation level.

摘要： A method for enhanced rate adaptation by a radio access network (RAN) node includes: determining a first code rate, for sending one or more messages to a user equipment (UE) before a first time, based at least in part on a first rank and a first message error rate; sending the one or more messages to the UE before the first time using the first code rate; receiving channel quality information and a second rank from the UE at the first time, wherein the second rank is different than the first rank; determining a second code rate, for sending one or more messages to the UE after the first time and before a second time, based at least in part on the received channel quality information and second rank; and sending the one or more messages to the UE, after the first time and before a second time, using the second code rate.

摘要： A method includes determining whether user equipment (UE) in a telecommunication network is configured to support evolved universal terrestrial radio access network dual connectivity (ENDC). Responsive to the UE being determined as configured to support the ENDC determining whether a source cell and a target cell are configured to support the ENDC. Performing on processing circuitry a first mobility modification in response to determining the source cell is an ENDC source cell and the target cell is a non-ENDC target cell. Performing on the processing circuitry a second mobility modification in response to determining the target cell is an ENDC target cell and the source cell is a non-ENDC source cell. The second mobility modification is different from the first mobility modification. Performing a handover from the source cell to the target cell in response to both the source cell and the target cell being configured for ENDC or non-ENDC.
