    摘要： Sequence selection techniques for Non-Orthogonal Multiple Access (NOMA) are provided. A User Equipment (UE) sends a request to a base station, the request indicating that the UE is to conduct at least one uplink transmission. The UE receives, in response to the request, an indicator of an expected system load, a value of the indicator including a total number of sequences expected to be used at one time for uplink transmissions in the system. The UE detects that at least two different pairs of sequences in a configured set of sequences have different cross correlation values, the sequences in the set configured for scrambling uplink transmissions. The UE selects, in response to the detecting and based on the indicator, at least one sequence with an improved cross correlation with at least one other sequence the at least one sequence and the at least one other sequence to be used for scrambling uplink transmissions within the system.

    摘要： Embodiments are directed towards embodiments are directed toward systems and methods for user plane function (UPF) and network slice load balancing within a 5G network. Example embodiments include systems and methods for load balancing based on current UPF load and thresholds that depend on UPF capacity; UPF load balancing using predicted throughput of new UE on the network based on network data analytics; UPF load balancing based on special considerations for low latency traffic; UPF load balancing supporting multiple slices, maintaining several load-thresholds for each UPF and each slice depending on the UPF and network slice capacity; and UPF load balancing using predicted central processing unit (CPU) utilization and/or predicted memory utilization of new UE on the network based on network data analytics.

    摘要： The random access (RA) procedure in NR-U can be improved by enable the NR-U capable UE to choose a suitable BWP and uses this chosen BWP to perform the RA procedure. A suitable BWP is a BWP with a low probability for LBT failure, such as a BWP having a load that is less than a threshold load. For example, whenever the UE has a RA procedure triggered, the UE selects the most suitable BWP based on load information, such as load measurements made by the UE for one or more available BWPs or load information communicated to the UE. The selected BWP for the RA procedure may be different from the UE's currently active BWP, and, in this case, the UE may do a BWP switch before the RA procedure.

    摘要： The present disclosure relates to a method for transmitting signals by a transmission end in a wireless communication system. In particular, the method includes configuring first and second type logical channel groups; receiving a first uplink grant; and transmitting buffer size information based on the uplink grant, wherein, when the first uplink grant is allowed to be used for transmission of buffer size information of the second logical channel group, the buffer size information includes the buffer size information of the first and second logical channel groups, and wherein, when the first uplink grant is not allowed to be used for transmission of buffer size information of the second logical channel group, the buffer size information includes the buffer size information of the first logical channel group.
