Definitions

  • the subject matter described herein relates to wireless communications and, in particular, carrier aggregation.
  • Carrier aggregation may enable increased bandwidth and, as such, increased data rates to a user equipment by aggregating carriers.
  • a user equipment such as a smart phone and the like, may be allocated a primary carrier serving a primary cell (Pcell) and one or more secondary carriers serving corresponding secondary cells (Scells).

  • Pcell primary cell
  • Scells secondary cells
  • These carriers may be continuous within the same frequency band, non-contiguous within a given frequency band, or non-contiguous among frequency bands.
  • the user equipment typically has multiple receiver chains to enable simultaneous reception from different center frequencies. In addition to carrier aggregation operation, these additional receiver chains can be utilized for performing inter-frequency mobility measurements and the like.
  • a user equipment which is not carrier aggregation capable or does not have multiple receiver chains that can be active simultaneously
  • signaling such as "interFreqNeedForGaps", implemented to provide the network with information regarding whether inter-frequency measurements require measurement gaps.
  • the method may include coupling, by a user equipment, to a base station serving as a primary cell for carrier aggregation; and sending, by the user equipment, at least one indication representative of a support for carrier aggregation by the user equipment and a need for at least one interrupt of traffic carried by the primary cell during a carrier aggregation operation with a secondary cell.
  • the secondary cell may be at a frequency, a band, or a combination of both different from the primary cell.
  • the at least on indication may be carried by an interFreqNeedForGaps information element 5 representative of the need for at least one interrupt of traffic carried by the Pcell during the carrier aggregation operation.
  • the carrier aggregation operation may include at least one of measuring the secondary cell at an inter-frequency carrier and activating the secondary cell.
  • FIG. 1 depicts an example of a system configured for signaling interrupts which may occur 20 during carrier aggregation operation, in accordance with some exemplary embodiments;
  • FIG. 2 depicts an example process for signaling interrupts which may occur during carrier aggregation operation, in accordance with some exemplary embodiments
  • FIG. 3 depicts an example of a user equipment, in accordance with some exemplary embodiments.
  • FIG. 4 depicts an example of a base station, in accordance with some exemplary embodiments.
  • user equipment may be capable of supporting carrier aggregation (CA)
  • CA carrier aggregation
  • the use of carrier aggregation by certain types of user equipment may actually cause interruptions to the reception of the Pcell due to the configuration and/or activation of one or more 35 secondary cell (Scells).
  • a user equipment having an integrated, single baseband chip solution capable of supporting carrier aggregation may be able to operate on the Pcell and Scell(s) simultaneously to receive signal from both cells, but when the Scell is initially configured (and activated), there can be one or more interruptions to the Pcell reception in order to for example adjust frequency synthesis correctly and perform other carrier aggregation operations.
  • some user equipment may be able to configure and/or activate Scells, without interrupts in Pcell reception.
  • the network may, in some example embodiments, be able to determine that the user equipment, when operating in carrier aggregation, will indeed have interrupts (for example, over the Pcell, when certain carrier aggregation operations are performed). These operations may include configuration and/or deconfiguration of one or more Scells, activation and/or deactivation of one or more Scells, and/or the like. As such, the network may determine (based on the signaling sent by user equipment) whether certain user equipment will cause interrupts under carrier aggregation operation. In some example embodiments, existing signaling may be re-purposed by the user equipment to inform the network of the need for interrupts, although dedicated signaling may be used as well.
  • the user equipment may inform the network including a base station whether the user equipment may cause interrupts during certain carrier aggregation operations.
  • the network may be informed by a message, such as a control message, a user equipment capabilities message, and/or any other type of message signaling the network that the user equipment has a need for interrupts during certain carrier aggregation.
  • the user equipment may inform the network whether it needs for interrupts. For example, the user equipment may signal a need for measurement gaps through one or more fields of an information element. Moreover, the need for interrupts may be signaled in an "interFreqNeedForGaps" information element of a capability information element, such as a user equipment capabilities information element sent to the network to inform the network of the user equipment's capabilities.
  • the "interFreqNeedForGaps" field may be provided per frequency band (for example, in "bandListEUTRA") or per band combination (for example, in "bandCombinationListEUTRA").

  • the network will be able to determine whether a certain user equipment supporting carrier aggregation may require interrupts as noted. However, if a user equipment signals carrier aggregation support without a need for interrupts, then network will be able to determine that the user equipment supporting carrier aggregation will not require interrupts.
  • InterFreqNeedForGaps other signaling may be used as well to convey whether a given user equipment supporting carrier aggregation requires interrupts (for example, in the Pcell during inter-frequency carrier aggregation procedures, such as during carrier aggregation configuration/measurements, activations, and the like).
  • the network may then determine that the user equipment will cause interruptions (for example, over the Pcell, when a Scell is configured and the like).
  • the network may then determine that because the user equipment would not require measurement gaps, the user equipment would not be causing interruptions when some Scell related procedure is performed on certain band combinations.
  • the network may instead determine that the user equipment will cause interruptions when a Scell is configured for the given band combination in carrier aggregation.
  • different levels of interruption classes may be defined to separate different types (or classes), such as whether interruptions are caused only for configuration, but not for activation/deactivation, or for a combination of both. Based on the defined classes, the signaling can be used to interpret in which kind of situations interruptions are caused.
