  • LCP logical channel priority
  • a logical channel priority (LCP) procedure is also utilized as part of the MAC layer in order to control how a user equipment uses an uplink grant to send data (such as how the UE multiplexes data onto transport block in uplink for example.
  • LCP in 5G is generally based on LCP in LTE, and includes configuring a PBR is per bearer (i.e. per logical channel) to ensure higher priority LCHs are scheduled first while avoiding the starvation of lower priority ones.
  • the PBR is used by the Token Bucket mechanisms such as described in 3GPP TS 38.321.
  • LCP is enhanced further with the introduction of logical channel restrictions, where the RRC may restrict the mapping of a logical channel to a subset of the configured cells, numerologies, PUSCH transmission durations and control whether a logical channel can utilize the resources allocated by an uplink grant for example.
  • a numerology generally corresponds to one subcarrier spacing in the frequency domain. By scaling a reference subcarrier spacing by an integer N, different numerologies can be defined. With such restrictions, it then becomes possible to reserve, for instance, the numerology with the largest subcarrier spacing and/or shortest PUSCH transmission duration for URLLC services.
  • a user equipment has an uplink rate control function which manages the sharing of uplink resources between logical channels, such as described in such as described in 3GPP TS 38.300.
  • RRC controls the uplink rate control function by giving each logical channel a priority, a prioritized bit rate (PBR) , and a buffer size duration (BSD) .
  • PBR prioritized bit rate
  • BSD buffer size duration
  • the uplink rate control function ensures that the UE serves the logical channel (s) in the following sequence:
  • the base station for example a gNB
  • the base station can guarantee the Guaranteed Flow Bit Rate (s) (GFBR (s) ) and ensure that neither the Maximum Flow Bit Rate (s) (MFBR (s) ) nor the UE-AMBR (Aggregated Maximum Bit Rate) are exceeded in uplink. If more than one logical channel has the same priority, the UE shall serve them equally.
  • LCP restrictions By configuring LCP restrictions in such a way that only one logical channel is allowed on a specific resource (such as a numerology or cell for example) , scheduling that resource individually allows to control how many resources are given to one logical channel.
  • a specific resource such as a numerology or cell for example
  • scheduling that resource individually allows to control how many resources are given to one logical channel may be too restrictive in practice as urgent data, such as SRB or URLLC for example, would typically have to be transmitted in all possible resources to benefit for instance from duplication.
  • Various example embodiments enable restrictions where the resource on which the bearer is mapped is not restricted and thus avoid, for example, restricting an URLLC to one resource.
  • a MAC control element comprises an indication of one or more logical channels that should not be transmitted in the uplink.
  • the MAC CE can be implemented in different ways.
  • the indication may explicitly signal an identifier (such as an LCID for example) of each logical channel, or the implicitly such as by using a bitmap.
  • the logical channels that are ‘flagged’ by this MAC CE would then be skipped in LCP and be considered as not having any data to send. It is noted that in some example the BSR reporting is unaffected so that it is ensured that buffered data is still being reported accurately. In this way the scheduler in the base station has to means to identify data being queued up and the need for the restriction to be lifted.
  • another MAC CE may be sent in order to lift the restriction.
  • a timer may be used. For example, the timer may be started upon receiving the MAC CE signaling the restriction and the restriction would be kept in place for as long as that timer is running.

  • the logical channel (s) may rely on the expiry of a timer started upon reception of the control element or by sending another MAC CE of the same format but identified with a different LCID to indicate that the restriction is lifted.
  • FIG. 2C shows a control element 204 having a dynamic size.
  • each logical channel that is identified in the control element 204 (namely, LCID 1 ... LCID N ) has a corresponding indication indicating whether that logical channel should be restricted or not.
  • the indications are represented by the 1-bit fields labeled as ‘S’ .
  • the field may be set to ‘1’ to indicate that a restriction is in place for that LCID while the field set to ‘0’ indicated that the restriction no longer applies.

  • the control element 206 identifies one logical channel. Similar to the example shown in FIG. 2C, a corresponding field indicates whether a restriction is in place for the one logical field.

Abstract

L'invention concerne un procédé consistant à recevoir des informations indiquant un ou plusieurs canaux logiques restreints d'un ensemble de canaux logiques permettant de commander une procédure de priorité de canal logique de telle sorte que des données desdits canaux logiques restreints ne puissent pas être envoyées sur des ressources de liaison montante ; à mettre en correspondance des données de l'ensemble de canaux logiques avec des ressources de liaison montante suivant la procédure de priorité de canal logique et les informations reçues ; et à transmettre les données sur la base de la mise en correspondance.
