Easily transportable devices with wireless telecommunications capabilities, such as mobile telephones, personal digital assistants, handheld computers, and similar devices, will be referred to herein as user equipment (UE). The term �user equipment� may refer to a device and its associated Universal Integrated Circuit Card (UICC) that includes a Subscriber Identity Module (SIM) application, a Universal Subscriber Identity Module (USIM) application, or a Removable User identity Module (R-UIM) application or may refer to the device itself without such a card. A UE might communicate with a second UE, some other element in a telecommunications network, an automated computing device such as a server computer, or some other device. A communications connection between a UE and another component might promote a voice call, a file transfer, or some other type of data exchange, any of which can be referred to as a call or a session.
Some UEs have the capability to communicate in a packet switched mode, wherein a data stream representing a portion of a call or session is divided into packets that are given unique identifiers. The packets might then be transmitted from a source to a destination along different paths and might arrive at the destination at different times. Upon reaching the destination, the packets are reassembled into their original sequence based on the identifiers. Voice over Internet Protocol (VoIP) is a well-known system for packet switched-based voice communication over the Internet. The term �VoIP� will refer herein to any packet switched voice call connected via the Internet, regardless of the specific technology that might be used to make the call.
The term �DRX� is used generically to refer to discontinuous reception. To avoid confusion, the terms �on-duration� and �off-duration� may also be used herein to refer to a UE's capability to receive data. Besides the on-duration, the active time defines the time that the UE is awake, which could be longer than the on-duration due to the possible inactivity timer running which will keep the UE awake for additional time. Additional related discussion is found in 3rd Generation Partnership Project (3GPP) Technical Specification (TS) 36.321.
Turning now to FIG. 3 a, RI control signal transmissions are discussed. A plurality of assigned periodic RI reporting intervals 250 are shown relative to the on-duration 210 and a retransmission window 230. In some contexts, the assigned periodic RI reporting intervals 250 may be referred to as assigned periodic RI reporting resources. The RI reporting intervals 250 depicted include a first RI reporting interval 250 a, a second RI reporting interval 250 b, a third RI reporting interval 250 c, a fourth RI reporting interval 250 d, a fifth RI reporting interval 250 e, a sixth RI reporting interval 250 f, a seventh RI reporting interval 250 g, an eighth RI reporting interval 250 h, a ninth RI reporting interval 250 i, a tenth RI reporting interval 250 j, an eleventh RI reporting interval 250 k, and a twelfth RI reporting interval 250 l. It is understood that the assigned periodic RI reporting intervals 250 in a network is an ongoing sequence, and that many RI reporting intervals 250 precede the first RI reporting interval 250 a and many RI reporting intervals 250 follow the twelfth RI reporting interval 250 l. In an embodiment, the UE 10 may transmit RI control signals during each RI reporting interval 250 using the assigned RI reporting resources, as indicated in FIG. 3 a by the solid line arrows. The retransmission window 230 provides an opportunity for the ENB 20 to retransmit data to the UE 10 that the UE 10 was unable to receive properly during the on-duration 210. Note that the UE 10 may transmit some of the PMI control signals during the on duration 210 and the retransmission window 230. This may require that the UE 10 have two or more antennas with two different RF chains�a first RF chain associated with a first antenna for receiving and a second RF chain associated with a second antenna for transmitting�so the UE 10 can receive and transmit concurrently.
The UE 10 includes a display 402. In an embodiment, the UE 10 includes two antennas 403�a first antenna 403A and a second antenna 403B�which may be used for MIMO operations. The two antennas 403 may also permit the UE 10 to transmit the RI control signals during the on-duration 210 and/or during the retransmission window 230 on the first antenna 403A while concurrently receiving signals sent by the ENB 20 to the UE 10 on the second antenna 403B. The UE 10 also includes a touch-sensitive surface, a keyboard or other input keys generally referred as 404 for input by a user. The keyboard may be a full or reduced alphanumeric keyboard such as QWERTY, Dvorak, AZERTY, and sequential types, or a traditional numeric keypad with alphabet letters associated with a telephone keypad. The input keys may include a trackwheel, an exit or escape key, a trackball, and other navigational or functional keys, which may be inwardly depressed to provide further input function. The UE 10 may present options for the user to select, controls for the user to actuate, and/or cursors or other indicators for the user to direct.
FIG. 8 illustrates a software environment 602 that may be implemented by the DSP 502. The DSP 502 executes operating system drivers 604 that provide a platform from which the rest of the software operates. The operating system drivers 604 provide drivers for the wireless device hardware with standardized interfaces that are accessible to application software. The operating system drivers 604 include application management services (�AMS�) 606 that transfer control between applications running on the UE 10. Also shown in FIG. 8 are a web browser application 608, a media player application 610, and Java applets 612. The web browser application 608 configures the UE 10 to operate as a web browser, allowing a user to enter information into forms and select links to retrieve and view web pages. The media player application 610 configures the UE 10 to retrieve and play audio or audiovisual media. The Java applets 612 configure the UE 10 to provide games, utilities, and other functionality. A component 614 might provide functionality related to RI transmission during DRX as described herein. Although the component 614 is shown in FIG. 8 at an application software level, the component 614 may be implemented at a lower system level than is illustrated in FIG. 8.
