Problems solved by technology

[0003] In some wireless systems, high-priority or delay-critical transmissions can negatively impact cell capacity because high-priority devices may transmit more data than the network expects
This can have an impact on access control, for example by negatively impacting the number of devices that can be supported
Quality of Service (QoS) enforcement for similar or lower priority flows can also be negatively impacted as high priority devices may take a larger share of network resources than they expect

Embodiment Construction

[0019] Figure 1A is a diagram illustrating an example communication system 100 in which one or more disclosed embodiments may be implemented. Communication system 100 may be a multiple access system that provides content, such as voice, data, video, messaging, broadcast, etc., to multiple wireless users. Communication system 100 may enable multiple wireless users to access such content by sharing system resources, including wireless bandwidth. For example, communication system 100 may employ one or more channel access methods such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), Single Carrier FDMA (SC-FDMA), zero-tail unique word DFT extended OFDM (ZT-UW DTS-s OFDM), unique word OFDM (UW-OFDM), resource block filter OFDM, filter bank multi-carrier (FBMC), etc.

[0020] Such as Figure 1A As shown, communication system 100 may include wireless transmit / receive units (WTRUs) 102a...

Abstract

A method performed by a WTRU may comprise associating a logical channel with a plurality of token buckets, including at least a long term token bucket and a short term token bucket. The method may further comprise transmitting logical channel data on the associated logical channel, in a TTI. The transmitted logical channel data of the TTI may be no larger than a value corresponding to a minimum ofthe long term token bucket and the short term token bucket. The long term token bucket may be initialized to a value which is greater than an initialized value of the short term token bucket. When the WTRU transmits logical channel data in a TTI, the WTRU may decrement the long term token bucket and the short term token bucket by a total size of one or more MAC SDUs served on the associated logical channel.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application Serial No. 62 / 668,585, filed May 8, 2018, which is hereby incorporated by reference in its entirety. Background technique [0003] In some wireless systems, high-priority or delay-critical transmissions may negatively impact cell capacity, since high-priority devices may transmit more data than the network expects. This may have an impact on access control, eg by negatively impacting the number of devices that can be supported. Quality of Service (QoS) enforcement for similar or lower priority flows can also be negatively impacted, as high priority devices may take up a larger share of network resources than their intended share. [0004] In the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE), radio bearers are served in order of their priority. Using logical channel prioritization (LCP), data from the logical channel with the highe...
