Description

Apparatus and method for feedback control during planning gaps in a data stream

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. patent application Ser. No. 14/315,201, filed Jun. 25, 2014, entitled “FEEDBACK CONTROL DURING PLANNEDGAPS IN DATA STREAMS,” the complete disclosure of which is incorporated herein by reference in its entirety for all purposes, except for those sections, if any, that are inconsistent with this specification.

Technical Field

The disclosed embodiments relate generally to the field of wireless communications, and more particularly, to feedback control during planning gaps in a data stream.

Background Art

When dual Subscriber Identity Module (SIM) dual standby is used in a smartphone, whenever a data connection occurs on the active (or "data") SIM, background data from an application may cause the idle (or "no data") SIM to be out of service. A phone containing active applications may have background data transmissions occupying 46% of the time, which causes the idle SIM to be unreachable a similar percentage of the time.

To address the above issues regarding reaching an idle SIM, Data-to-Paging (DvP) gaps have been introduced to create gaps in the data stream that enable paging of an idle SIM. This allows the idle SIM to remain in service and receive incoming calls while data transfers are ongoing on the active SIM.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings which form a part hereof, wherein like numerals designate like parts throughout, and wherein the drawings show by way of illustrative embodiments that may be practiced. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure.

Various operations may be described as multiple discrete actions or operations in a manner that best helps understand the claimed subject matter. However, the order of description should not be construed as implying that the operations are necessarily order-dependent. Specifically, the operations may not be performed in the order in which they are presented. The described operations may be performed in an order different from that of the described embodiment. Various additional operations may be performed and/or the described operations may be omitted in additional embodiments.

For purposes of this disclosure, the phrase "A and/or B" means (A), (B), or (A and B). For purposes of this disclosure, the phrase "A, B, and/or C" means (A), (B), (C), (A and B), (A and C), (B and C), or (A, B, and C). The description may use the phrases "in one embodiment" or "in an embodiment," which may both refer to one or more of the same or different embodiments. Furthermore, the terms "comprising," "including," "having," and the like, as used with respect to embodiments of the present disclosure, are synonymous.

As used herein, the term "circuitry" may refer to, be a part of, or include an application specific integrated circuit ("ASIC"), an electronic circuit, a processor (shared, dedicated, or group) and/or memory (shared, dedicated, or group) that executes one or more software or firmware programs, combinational logic circuits, and/or other suitable hardware components that provide the described functionality.

As described above, idle mode gaps (e.g., DvP gaps) are provided in the data stream corresponding to the active SIM so that the idle SIM can perform idle mode operations, such as sending/receiving paging and/or other idle mode signaling. The idle mode gaps for reading paging and/or other idle mode signaling for the idle SIM can be generated by simply removing control of the antenna from the active SIM for a short period of time (e.g., 20 ms for receiving paging messages). From the network's perspective, this may appear as if the data SIM is out of service for only this short period of time.

Taking a data SIM out of service, even for a short period, can result in a significant drop in data throughput. In some instances, this drop can be as high as 36%. This can be attributed, at least in part, to the fact that measurement reports are periodically sent to the network. During the period when the active SIM is out of service, the measurement reports may indicate poor data reception, which may be associated with poor channel conditions. In response, the network may use a more conservative modulation and coding scheme (MCS) (which is associated with lower data throughput) so that data can be successfully transmitted despite the poor channel conditions. Consequently, reduced data throughput may occur even after an idle mode gap.

The disclosed embodiments provide a feedback control mechanism that enables a faster return to full data throughput after an idle mode gap. Because the idle mode gap has a known length, the communication system can more quickly return to full data transfer speed by sending a measurement report once the idle mode gap ends. Instead of basing the measurement report on measurements performed during the idle mode gap, the measurement report can instead be based on the radio performance immediately before the idle mode gap. This scenario may correspond to a best description/measurement of the actual radio conditions.

FIG1 schematically illustrates a wireless communication environment 100 according to various embodiments. The environment 100 may include a user equipment (UE) 104 in wireless communication with an access node (e.g., an enhanced Node B (eNB)) 108. The eNB 108 may be part of a 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) network (e.g., an LTE Advanced (LTE-A) network). In particular, the eNB 108 may be part of a radio access network (RAN) of the LTE/LTE-A network (e.g., an Evolved Universal Terrestrial Radio Access Network (E-UTRAN)). The E-UTRAN may be coupled to a core network (e.g., an Evolved Packet Core (EPC)), which performs various management and control functions for the LTE/LTE-A network and further provides a communication interface between various RANs and other networks.

UE 104 may include communication circuitry 112 configured to provide communication services for multiple subscriber identity modules (SIMs) coupled thereto. Multiple SIMs may be coupled to communication circuitry 112 via SIM port 114. Multiple SIMs may include, for example, SIM1 116 and SIM2 120. A SIM may be an integrated circuit that securely stores subscriber identity information (e.g., an International Mobile Subscriber Identity (IMSI)) and related keys used to identify and authenticate one or more subscribers using UE 104. Each SIM may be associated with different subscriber identity information and may or may not be associated with a different operator. In some embodiments, the SIM may be removably coupled to communication circuitry 112. In other embodiments, the SIM may be hardware and/or firmware permanently coupled to UE 104. In various embodiments, the SIM may include a full-size SIM, a mini SIM, a micro SIM, a nano SIM, an embedded SIM, and/or a virtual SIM.

The communication circuitry 112 may transmit and receive data and control signals through a wireless transceiver 124 , which provides various amplification, up/down conversion, and filtering functions. The wireless transceiver 124 may facilitate over-the-air communications via one or more antennas 128 .

UE 104 may also include feedback control circuitry 132 coupled to communication circuitry 112 and/or wireless transceiver 124. Feedback control circuitry 132 may generally control feedback measurements and reporting performed by UE 104. For example, feedback control circuitry 132 may perform various channel measurements in a downlink channel while receiving a data stream from eNB 108 to measure the quality of the channel. Feedback control circuitry 132 may determine appropriate feedback information based on these channel measurements. For example, feedback control circuitry 132 may measure a signal-to-interference-and-noise ratio (SINR) and, based on the SINR and characteristics of wireless transceiver 124, select a channel quality indicator (CQI) that indicates the data rate that the channel can support. The feedback information may then be sent to eNB 108 in an uplink channel.

While SINR is discussed as a channel measurement, other embodiments may additionally/alternatively perform other channel measurements (eg, but not limited to, block error rate, frame error rate, bit error rate, etc.).

2 is a flow chart 200 illustrating a feedback control method according to some embodiments. The communication circuit 112 and/or the feedback control circuit 132 may perform the feedback control method.

The feedback control method may include, at 204, processing a data stream of a first SIM (e.g., SMI1 116). The data stream may be a downlink data stream received at the UE 104 from a RAN transmission point. In various embodiments, the RAN transmission point may be an eNB 108, a remote radio head (RRH) controlled by the eNB 108, or some other network entity. Processing of the data stream may be performed by the communication circuitry 112 and may include various signal processing operations (e.g., but not limited to, demodulation, decoding, etc.).

The feedback control method may include, at 208, generating a feedback measurement based on the data stream. The generation of the feedback measurement may be performed by the feedback control circuit 132. In some embodiments, the feedback measurement may be a SINR measurement based on the received data stream. In some embodiments, the SINR measurement may be performed on a control signal or a reference signal embedded in the data stream.

The feedback control method may further include, at 212, generating and transmitting a feedback message based on the feedback measurement. Generating and transmitting the feedback message may be performed by feedback control circuitry 132. Feedback control circuitry may employ other circuitry (e.g., communication circuitry 112, wireless transceiver 124, and/or antenna 128) to implement transmission of the feedback message. In some embodiments, feedback control circuitry 132 may generate the feedback message such that it includes an indicator (e.g., a channel quality indicator (CQI)) that provides an indication that the channel has a particular channel condition.

Feedback control circuitry 132 may select a CQI index that corresponds to a particular modulation, code rate, and efficiency as appropriate based on feedback measurements. For example, if a channel is associated with a high SINR, feedback control circuitry 132 may select a high CQI index (e.g., 15) that corresponds to 64-bit quadrature amplitude modulation (QAM) with a code rate of 948 x 1024 and an efficiency of 5.5547. For example, if a channel is associated with a low SINR, feedback control circuitry 132 may select a low CQI index (e.g., 1) that corresponds to quadrature phase shift keying (QPSK) with a code rate of 78 x 1024 and an efficiency of 0.1523. In some embodiments, the CQI may be a four-bit value corresponding to the CQI index shown in Table 7.2.3-1 of 3GPP Technical Specification (TS) 36.213 V12.41.0 (2014-03).

In some embodiments, feedback control circuitry 132 may cooperate with communication circuitry 112 to send the feedback message.In various embodiments, the feedback message may be sent on a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

The feedback control method may further include, at 216, interrupting the reception of the data stream. Interrupting reception may be performed by communication circuitry 112 for the benefit of a second SIM (e.g., SIM2 120). Reception may be interrupted for a predetermined period (also referred to as an idle mode gap) in order to attempt to send/receive an idle mode message (e.g., a paging message, a received signal strength indication (RSSI) measurement message, a neighboring cell RSSI measurement message, a cell broadcast message, or a neighboring cell system information message) for the idle SIM (e.g., SIM2 120). Communication circuitry 112 may have known in advance when these idle mode gaps will occur and how long they will last. This may allow communication circuitry 112 to synchronize with the network entity that sends the idle mode message.

Interrupting reception may be accomplished by the communication circuitry 112 removing control of receive chain components, which may be located in the wireless transceiver 124 and antenna 128, from SIM1 116 and providing control of the receive chain components to SIM2 120. SIM control of the receive chain components may mean that the SIM will have direct control of the components or, more likely, that the communication circuitry 112 will control the receive chain components to handle communications associated with the SIM.

After interrupting reception for a predetermined period of time, the feedback control method may further include, at 220, generating a post-idle mode gap feedback message based on the pre-idle mode gap feedback measurement. For example, if a high SINR is measured before the idle mode gap, resulting in a high CQI index (e.g., 15), and conveyed in the feedback message, then after the idle mode gap, the feedback control circuit 132 may generate another feedback message including a CQI index of 15 and may send this feedback message to indicate that the channel conditions during or after the idle mode gap are the same as those before the idle mode gap. Thus, the feedback message sent after interrupting reception of the data stream will be based on measurements taken before the interruption, rather than after the interruption. In this way, one or more channel feedback measurements can be reused to indicate that the channel conditions during or immediately after the idle mode gap are the same as those before the idle mode gap.

FIG3 illustrates a channelization coding plot 300 according to an embodiment of the present invention. Plot 300 provides a visual indication of the modulation scheme for each packet of a data stream for a first SIM. Packets transmitted before an idle mode gap 304 may have 64QAM, which may be associated with relatively high network efficiency (wherein network efficiency increases vertically on plot 300). During idle mode gap 304, no packets may be received in the data stream. After idle mode gap 304, typical protocols may transmit feedback measurements reflecting poor channel conditions (based on, for example, the lack of data packets received during idle mode gap 304), which may lead the eNB to determine that channel conditions have deteriorated and that more conservative modulation is necessary. Consequently, packets transmitted after idle mode gap 304 may have 16QAM, which may be associated with relatively low network efficiency (as reflected by the packets located in the lower portion of plot 300). The drop in modulation scheme is shown to occur some time after idle mode gap 304 due to feedback delay. After the UE receives a certain number of packets (5 shown) at the reduced modulation scheme, the modulation scheme may be restored to full speed 64-QAM.

This is in contrast to the disclosed embodiment. Callout 308 illustrates channelization coding after idle mode gap 304 according to the disclosed embodiment. Callout 308 illustrates stable use of a high-efficiency modulation scheme (i.e., 64QAM). This is achieved because the feedback measurements corresponding to idle mode gap 304 indicate the same channel conditions as those generated before idle mode gap 304. Therefore, the eNB does not determine that channel conditions have deteriorated and move to a more conservative modulation scheme. Instead, five packets will be able to transmit data using the more efficient modulation scheme.
