[0003] This patent application claims priority to U.S. Application No. 17 / 087,282, filed on November 2, 2020, and the benefit of and priority to U.S. Provisional Application No. 62 / 930,541, filed on November 4, 2019, which is assigned to the assignee of the present application and is hereby expressly incorporated herein by reference in its entirety as if fully set forth below and for all applicable purposes. Technical Field

[0004] Aspects of the present disclosure relate to wireless communications, and more particularly, to methods and apparatus for energy saving techniques. Background Art

[0005] Wireless communication systems are widely deployed to provide various telecommunication services, such as telephony, video, data, messaging, broadcast, etc. These wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access systems include the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) system, the Advanced LTE (LTE-A) system, the Code Division Multiple Access (CDMA) system, the Time Division Multiple Access (TDMA) system, the Frequency Division Multiple Access (FDMA) system, the Orthogonal Frequency Division Multiple Access (OFDMA) system, the Single Carrier Frequency Division Multiple Access (SC-FDMA) system, and the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, etc.

[0006] In some examples, a wireless multiple access communication system may include multiple base stations (BSs) that are capable of supporting communication of multiple communication devices (also referred to as user equipment (UE)) simultaneously. In an LTE or LTE-A network, one or more base station sets may define an eNodeB (eNB). In other examples (e.g., in a next generation or 5G network), a wireless multiple access communication system may include multiple distributed units (DUs) (e.g., edge units (EUs), edge nodes (ENs), radio heads (RHs), smart radio heads (SRHs), transmission reception points (TRPs), etc.) communicating with multiple central units (CUs) (e.g., central nodes (CNs), access node controllers (ANCs), etc.), wherein a group of one or more distributed units communicating with the central unit may define an access node (e.g., a new radio base station (NR BS), a new radio node B (NR NB), a network node, a 5G NB, an eNB, a next generation node B (gNB), etc.). A base station or DU may communicate with a set of UEs on a downlink channel (e.g., for transmission from a base station or to a UE) and an uplink channel (e.g., for transmission from a UE to a base station or a distributed unit).

[0007] These multiple access technologies have been adopted by various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at municipal, national, regional, and even global levels. New Radio (e.g., 5G NR) is an example of an emerging telecommunication standard. NR aims to better support mobile broadband Internet access by increasing spectral efficiency, reducing costs, improving services, utilizing new spectrum, better integrating with other open standards using OFDMA with cyclic prefix (CP) on both downlink (DL) and uplink (UL), supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

[0008] As demand for mobile broadband access continues to increase, it is desirable to further improve NR technology. Preferably, these improvements should be applicable to other multi-access technologies and the telecommunication standards that employ them. Summary of the invention

[0035] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for New Radio (NR) (NR access technology or 5G technology).

[0036] NR can support various wireless communication services, such as enhanced mobile broadband (eMBB) for wide bandwidth (e.g., above 80MHz), millimeter wave (mmW) for high carrier frequency (e.g., 60GHz), massive MTC (mMTC) for non-backward compatible MTC technology, and / or mission critical ultra-reliable low latency communication (URLLC). These services may include latency and reliability requirements. These services may also have different transmission time intervals (TTIs) to meet their respective quality of service (QoS) requirements. In addition, these services can coexist in the same subframe.

[0037] The following description provides an example of updating energy-saving behavior simultaneously across multiple frequency resource sets, and does not limit the scope, applicability, or examples set forth in the claims. Without departing from the scope of the present disclosure, the functions and arrangements of the elements discussed may be changed. Various examples may omit, replace, or add various programs or components as appropriate. For example, the described method may be performed in a different order than described, and various steps may be added, omitted, or combined. In addition, the features described with respect to some examples may be combined in some other examples. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method that is practiced using other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims. The word "exemplary" is used herein to mean "as an example, instance, or illustration". Any aspect described herein as "exemplary" is not necessarily to be interpreted as being preferred or superior to other aspects.

[0038] The technology described herein can be used in various wireless communication networks, such as LTE, CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network can implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. CDMA2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network can implement radio technologies such as Global System for Mobile Communications (GSM). An OFDMA network can implement radio technologies such as NR (e.g., 5G RA), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE802.20, Flash-OFDMA, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunications System (UMTS). NR is an emerging wireless communication technology jointly developed with the 5G Technology Forum (5GTF). 3GPP Long Term Evolution (LTE) and LTE Advanced (LTE-A) are versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). "LTE" generally refers to LTE, LTE-Advanced (LTE-A), LTE in unlicensed spectrum (LTE-Space), etc. The techniques described herein can be used for the above-mentioned wireless networks and radio technologies as well as other wireless networks and radio technologies. For clarity, although terms commonly associated with 3G and / or 4G wireless technologies may be used herein to describe various aspects, various aspects of the present disclosure may be applied to other communication systems based on generations, such as 5G and higher, including NR technologies.

[0039] Example Wireless Communication System

[0040] Figure 1 An example wireless communication network 100 is shown in which aspects of the present disclosure may be performed. For example, the wireless communication network 100 may be a new radio (NR) system (e.g., a 5G NR network). Figure 1 As shown, the wireless communication network 100 may include one or more user equipment (UE) 120, which is configured to perform Fig. 9The operations 900 of the present invention may be performed to simultaneously apply common energy saving behaviors across multiple sets of frequency resources (e.g., bandwidth parts (BWPs) or component carriers (CCs)). Similarly, the wireless communication network 100 may include one or more base stations (BSs) 110 (e.g., network entities) configured to perform Fig.10 Operation 1000 for configuring execution Fig. 9 The present invention provides a method for operating and communicating with a UE 120 of the present invention.

[0041] like Figure 1 As shown, the wireless communication network 100 may include multiple BSs 110 and other network entities. The BS may be a station that communicates with the UE. Each BS 110 may provide communication coverage for a specific geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​a Node B and / or a Node B subsystem serving the coverage area, depending on the context in which the term is used. In the NR system, the term "cell" and eNB, Node B, 5G NB, AP, NR BS, NRBS, gNB, or TRP may be interchangeable. In some examples, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move according to the location of the mobile base station. In some examples, the BS may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (e.g., direct physical connections, virtual networks, etc.).

[0042] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0043] A BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs of users in a home, etc.). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown, BSs 110a, 110b, and 110c may be macro BSs for macro cells 102a, 102b, and 102c, respectively. BS 110x may be a pico BS for pico cell 102x. BSs 110y and 110z may be femto BSs for femto cells 102y and 102z, respectively. A BS may support one or more (e.g., three) cells.

[0044] The wireless communication network 100 may also include a relay station. A relay station receives transmissions of data and / or other information from an upstream station (e.g., a BS or a UE) and sends transmissions of data and / or other information to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that relays transmissions for other UEs. Figure 1 In the example shown, a relay station 110r may communicate with a BS 110a and a UE 120r to facilitate communication between the BS 110a and the UE 120r. A relay station may also be referred to as a relay BS, a relay, or the like.

[0045] The wireless communication network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relays, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 20 watts), while a pico BS, a femto BS, and a relay may have a lower transmit power level (e.g., 1 watt).

[0046] The wireless communication network 100 may support synchronous or asynchronous operation. For synchronous operation, the BSs may have similar frame timing, and transmissions from different BSs may be approximately aligned in time. For asynchronous operation, the BSs may have different frame timing, and transmissions from different BSs may not be aligned in time. The techniques described herein may be used for both synchronous and asynchronous operation.

[0047] A network controller 130 may couple to a set of BSs and provide coordination and control for these BSs. The network controller 130 may communicate with the BSs 110 via a backhaul. The BSs 110 may also communicate with each other, directly or indirectly, for example, through a wireless or wired backhaul.

[0048] UE 120 (e.g., 120x, 120y, etc.) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. UE may also be referred to as a mobile station, a terminal, an access terminal, a subscriber unit, a station, a customer premises equipment (CPE), a cellular phone, a smart phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a notebook computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or medical equipment, a healthcare device, a biometric sensor / device, a wearable device (such as a smart watch, smart clothing, smart glasses, virtual reality goggles, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet, etc.)), an entertainment device (e.g., a music device, a video device, a satellite radio, etc.), a vehicle component or sensor, a smart meter / sensor, a robot, a drone, an industrial manufacturing device, a positioning device (e.g., GPS, Beidou, ground), or any other suitable device configured to communicate via a wireless or wired medium. Some UEs may be considered machine type communication (MTC) devices or evolved MTC (eMTC) devices, which may include remote devices that can communicate with a base station, another remote device, or some other entity. Machine type communication (MTC) may refer to communication involving at least one remote device at at least one end of the communication, and may include a form of data communication involving one or more entities that do not necessarily require human interaction. For example, an MTC UE may include a UE capable of MTC communication with an MTC server and / or other MTC devices via a public land mobile network (PLMN). MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, cameras, location tags, etc., which can communicate with a BS, another device (e.g., a remote device), or some other entity. For example, a wireless node may provide connectivity to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. MTC UEs, as well as other UEs, may be implemented as Internet of Things (IoT) devices, such as narrowband IoT (NB-IoT) devices.

[0049] exist Figure 1 In FIG. 1 , a solid line with double arrows represents desired transmission between a UE and a serving BS, which is a BS designated to serve the UE on a downlink and / or uplink. A dashed line with double arrows represents interfering transmission between the UE and the BS.

[0050] Some wireless networks (e.g., LTE) utilize orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are also commonly referred to as tones, bins, etc. Each subcarrier can be modulated with data. In general, modulation symbols are transmitted in the frequency domain using OFDM and in the time domain using SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. For example, the spacing between subcarriers can be 15kHz, and the minimum resource allocation (called a "resource block") can be 12 subcarriers (or 180kHz). Therefore, for system bandwidths of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), the nominal FFT size can be equal to 128, 256, 512, 1024, or 2048, respectively. The system bandwidth can also be divided into subbands. For example, a subband may cover 1.08 MHz (eg, 6 resource blocks), and there may be 1, 2, 4, 8, or 16 subbands for system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz, respectively.

[0051] Although aspects of the examples described herein may be associated with LTE technology, aspects of the present disclosure may be applicable to other wireless communication systems, such as NR. NR may use OFDM with a cyclic prefix (CP) on the uplink and downlink, and include support for half-duplex operation using time division duplex (TDD). A single component carrier bandwidth of 100 MHz may be supported. NR resource blocks may span 12 subcarriers with a subcarrier bandwidth of 75 kHz and a duration of 0.1 ms. Each radio frame may consist of 50 subframes of 10 milliseconds in length (period). Thus, each subframe may be 0.2 ms in length. In some cases, a subframe may have a length (duration) of 1 millisecond, and each subframe may be further divided into two slots, each of which is 0.5 milliseconds (e.g., each slot contains 6 or 7 OFDM symbols, depending on the CP length). A slot may be further divided into mini-slots, each of which has a shorter duration (e.g., contains fewer symbols than a full slot). Each subframe may indicate a link direction (e.g., DL or UL) for data transmission, and the link direction of each subframe may be switched dynamically. Each subframe may include DL / UL data as well as DL / UL control information. Beamforming can be supported, and the beam direction can be dynamically configured. Multiple-input multiple-output (MIMO) transmission with precoding can also be supported. The MIMO configuration in the DL can support up to 8 transmit antennas, multi-layer DL transmission of up to 8 streams, and up to 2 streams per UE. Multi-layer transmission of up to 2 streams per UE can be supported. Aggregation of multiple cells of up to 8 serving cells can be supported. Alternatively, NR can support different air interfaces instead of being based on OFDM. The NR network may include entities such as a central unit (CU) and / or a distributed unit (DU).

[0052] In some examples, access to the air interface can be scheduled, wherein a scheduling entity (e.g., BS) allocates resources for communication between some or all devices and equipment within its service area or cell. In the present disclosure, as further discussed below, a scheduling entity may be responsible for scheduling, allocating, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communications, subordinate entities utilize resources allocated by the scheduling entity. BS is not the only entity that can act as a scheduling entity. That is, in some examples, UE can be used as a scheduling entity to schedule resources for one or more subordinate entities (e.g., one or more other UEs). In this example, UE acts as a scheduling entity, and other UEs utilize resources scheduled by UE for wireless communication. UE can be used as a scheduling entity in a peer-to-peer (P2P) network and / or a mesh network. In the mesh network example, in addition to communicating with the scheduling entity, UEs can also optionally communicate directly with each other.

[0053] Thus, in a wireless communication network having scheduled access to time-frequency resources and having a cellular configuration, a P2P configuration, and a mesh configuration, a scheduling entity and one or more slave entities may communicate using the scheduled resources.

[0054] As described above, the RAN may include a CU and a DU. A NR BS (e.g., an eNB, a 5G Node B, a Node B, a transmission reception point (TRP), an access point (AP)) may correspond to one or more BSs. An NR cell may be configured as an access cell (ACell) or a data-only cell (DCell). For example, a RAN (e.g., a central unit or a distributed unit) may configure a cell. A DCell may be a cell for carrier aggregation or dual connectivity, but not for initial access, cell selection / reselection, or switching. In some cases, a DCell may not send a synchronization signal (SS) - in some cases, a DCell may send an SS. The NR BS may send a downlink signal indicating the cell type to the UE. Based on the cell type indication, the UE may communicate with the NR BS. For example, the UE may determine, based on the indicated cell type, an NR BS to be considered for cell selection, access, switching, and / or measurement.

[0055] Figure 2 An example architecture of a distributed radio access network (RAN) 200 is shown, which may be Figure 1 . The 5G access node 206 may include an access node controller (ANC) 202. The ANC may be a CU of the distributed RAN 200. The backhaul interface to the next generation core network (NG-CN) 204 may terminate at the ANC. The backhaul interface to the adjacent next generation access node (NG-AN) may terminate at the ANC. The ANC may include one or more TRPs 208 (which may also be referred to as BS, NR BS, Node B, 5G NB, AP, gNB or some other terminology). As described above, TRP may be used interchangeably with "cell".

[0056] The TRP 208 may be a DU. The TRP 208 may be connected to one ANC (ANC 202) or more than one ANC (not shown). For example, for RAN sharing, Radio as a Service (RaaS), and service-specific AND deployments, the TRP may be connected to multiple ANCs. The TRP may include one or more antenna ports. The TRP may be configured to provide services to the UE individually (e.g., dynamically selected) or jointly (e.g., joint transmission).

[0057] The distributed RAN 200 can support fronthaul solutions across different deployment types. For example, the RAN 200 architecture can be based on transport network capabilities (e.g., bandwidth, latency, and / or jitter). The distributed RAN 200 can share features and / or components with LTE. For example, the next generation AN (NG-AN) 210 can support dual connectivity with NR and can share a common fronthaul for LTE and NR. The distributed RAN 200 can enable cooperation between TRPs 208. For example, cooperation can be preset within and / or across TRPs via the ANC 202. Depending on the aspect, a cross-TRP interface may not be required / existent.

[0058] According to various aspects, dynamic configuration of separate logical functions may exist within the distributed RAN 200. Figure 5 As described in more detail, the radio resource control (RRC) layer, the packet data convergence protocol (PDCP) layer, the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical (PHY) layer may be adaptively placed in the DU or CU (e.g., TRP or ANC, respectively). According to certain aspects, the BS may include a central unit (CU) (e.g., ANC 202) and / or one or more distributed units (e.g., one or more TRPs 208).

[0059] Figure 3 An example physical architecture of a distributed RAN 300 according to aspects of the present disclosure is shown. A centralized core network unit (C-CU) 302 may host core network functions. The C-CU may be centrally deployed. C-CU functions may be offloaded (e.g., to Advanced Wireless Services (AWS)) to handle peak capacity.

[0060] A centralized RAN unit (C-RU) 304 may host one or more ANC functions. Optionally, the C-RU may host core network functions locally. The C-RU may have a distributed deployment. The C-RU may be closer to the network edge.

[0061] DU 306 may host one or more TRPs (edge ​​node (EN), edge unit (EU), radio head (RH), smart radio head (SRH), etc.) DU may be located at the edge of the network with radio frequency (RF) capabilities.

[0062] Figure 4 BS 110 and UE 120 (eg Figure 1) that may be used to implement various aspects of the present disclosure. As described above, BS 110 may include a TRP. One or more components of BS 110 and UE 120 may be used to practice aspects of the present disclosure. For example, antenna 452, processors 466, 458, 464, and / or controller / processor 480 (for implementing transceiver or separate receiver and transmitter chain functions) of UE 120 may be used to perform Fig. 9 Operation 900 of BS 110, and / or antenna 434, processor 430, 420, 438 and / or controller / processor 440 of BS 110 may be used to perform Fig.10 Operation 1000.

[0063] Figure 4 1 shows a block diagram of a design of a BS 110 and a UE 120, which may be Figure 1 For the restricted association scenario, BS 110 may be Figure 1 1. The macro BS 110c in FIG. 1 may be the macro BS 110c, and the UE 120 may be the UE 120y. The BS 110 may also be some other type of BS. The BS 110 may be equipped with antennas 434a to 434t, and the UE 120 may be equipped with antennas 452a to 452r.

[0064] At BS 110, a transmit processor 420 may receive data from a data source 412 and control information from a controller / processor 440. The control information may be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid ARQ indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), etc. The data may be for a physical downlink shared channel (PDSCH), etc. The processor 420 may process (e.g., encode and symbol map) the data and the control information to obtain data symbols and control symbols, respectively. The processor 420 may also generate reference symbols, e.g., for a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a cell-specific reference signal (CRS). If applicable, a transmit (TX) multiple-input multiple-output (MIMO) processor 430 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, and / or reference symbols, and may provide output symbol streams to modulators (MODs) 432a to 432t. Each modulator 432 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 432 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The downlink signals from modulators 432a through 432t may be transmitted via antennas 434a through 434t, respectively.

[0065] At UE 120, antennas 452a to 452r can receive downlink signals from base station 110, and can provide received signals to demodulators (DEMOD) 454a to 454r, respectively. Each demodulator 454 can adjust (e.g., filter, amplify, downconvert and digitize) the corresponding received signal to obtain input samples. Each demodulator 454 can further process the input samples (e.g., for OFDM, etc.) to obtain input symbols. MIMO detector 456 can obtain received symbols from all demodulators 454a to 454r, perform MIMO detection on the received symbols if applicable, and provide detection symbols. For example, MIMO detector 456 can provide detection RS sent using the technology described herein. Receive processor 458 can process (e.g., demodulate, deinterleave and decode) the detected symbols, provide decoded data for UE 120 to data receiver 460, and provide decoding control information to controller / processor 480. According to one or more aspects, CoMP aspects may include providing antennas and some TX / RX functions so that they reside in distributed units. For example, some TX / RX processing may be done in a central unit, while other processing may be done in distributed units. For example, according to one or more aspects shown in the figure, BS modulation / demodulation 432 may be in a distributed unit.

[0066] On the uplink, at the UE 120, a transmit processor 464 may receive and process data from a data source 462 (e.g., for a physical uplink shared channel (PUSCH)) and control information from a controller / processor 480 (e.g., for a physical uplink control channel (PUCCH)). The transmit processor 464 may also generate reference symbols for reference signals (e.g., for a sounding reference signal (SRS)). The symbols from the transmit processor 464 may be precoded by a TX MIMO processor 466, if applicable, further processed by demodulators 454a through 454r (e.g., for SC-FDM, etc.), and transmitted to the BS 110. At the BS 110, the uplink signals from the UE 120 may be received by the antenna 434, processed by the modulator 432, detected by the MIMO detector 436 (if applicable), and further processed by the receive processor 438 to obtain decoded data and control information transmitted by the UE 120. The receive processor 438 may provide the decoded data to the data receiver 439 and the decoded control information to the controller / processor 440 .

[0067] Controllers / processors 440 and 480 may direct the operations at BS 110 and UE 120, respectively. Processor 440 and / or other processors and modules at BS 110 may perform or direct the operations described herein. Fig.10 The processor 480 and / or other processors and modules at the UE 120 may also execute or direct the process of the technology described in this document. Fig. 9 Memories 442 and 482 may store data and program codes for BS 110 and UE 120, respectively. Scheduler 444 may schedule UEs for data transmission on the downlink and / or uplink.

[0068] Figure 5 A diagram 500 of an example for implementing a communication protocol stack according to aspects of the present disclosure is shown. The communication protocol stack shown can be implemented by a device operating in a wireless communication system such as a 5G NR system (e.g., a wireless communication network 100) (e.g., a system supporting uplink-based mobility). Diagram 500 shows a communication protocol stack, including a radio resource control (RRC) layer 510, a packet data convergence protocol (PDCP) layer 515, a radio link control (RLC) layer 520, a medium access control (MAC) layer 525, and a physical (PHY) layer 530. In various examples, the layers of the protocol stack can be implemented as separate software modules, portions of a processor or ASIC, portions of non-colocated devices connected by a communication link, or various combinations thereof. For example, co-located and non-co-located implementations can be used in a protocol stack for a network access device (e.g., AN, CU, and / or DU) or a UE.

[0069] The first option 505-a illustrates a split implementation of the protocol stack, where the implementation of the protocol stack is performed on a centralized network access device (e.g., Figure 2 ANC 202 in ) and distributed network access equipment (e.g., Figure 2 In the first option 505-a, the RRC layer 510 and the PDCP layer 515 may be implemented by the CU, and the RLC layer 520, the MAC layer 525, and the PHY layer 530 may be implemented by the DU. In various examples, the CU and the DU may be collocated or not. The first option 505-a may be useful in macro cell, micro cell, or pico cell deployments.

[0070] The second option 505-b shows a unified implementation of the protocol stack, where the protocol stack is implemented in a single network access device (e.g., access node (AN), new radio base station (NR BS), new radio node B (NR NB), network node (NN), etc.). In the second option, the RRC layer 510, the PDCP layer 515, the RLC layer 520, the MAC layer 525, and the PHY layer 530 can all be implemented by the AN. The second option 505-b may be useful in femtocell deployment.

[0071] Regardless of whether the network access device implements part or all of the protocol stack, the UE can implement the entire protocol stack (eg, the RRC layer 510, the PDCP layer 515, the RLC layer 520, the MAC layer 525, and the PHY layer 530).

[0072] Figure 6 A diagram showing an example of a frame format 600 for NR is shown. The transmission timeline for each of the downlink and uplink may be divided into radio frame units. Each radio frame may have a predetermined duration (e.g., 10 ms) and may be divided into 10 subframes, each of which is 1 ms and indexed from 0 to 9. Depending on the subcarrier spacing, each subframe may include a variable number of slots. Each slot may include a variable number of symbol periods (e.g., 7 or 14 symbols), depending on the subcarrier spacing. The symbol periods in each slot may be assigned an index. A small slot, which may be referred to as a subslot structure, refers to a transmission time interval having a duration less than a slot (e.g., 2, 3, or 4 symbols). Each symbol in a slot may indicate a link direction (e.g., DL, UL, or flexible) for data transmission, and the link direction of each subframe may be dynamically switched. The link direction may be based on the slot format. Each slot may include DL / UL data and DL / UL control information.

[0073] In NR, a synchronization signal (SS) block is transmitted. The SS block includes PSS, SSS, and dual-symbol PBCH. The SS block can be transmitted at a fixed time slot position, such as Figure 6Symbols 0-3 are shown. PSS and SSS can be used by UE for cell search and acquisition. PSS can provide half-frame timing, and SS can provide CP length and frame timing. PSS and SSS can provide cell identification. PBCH carries some basic system information, such as downlink system bandwidth, timing information within a radio frame, SS pulse set period, system frame number, etc. SS blocks can be organized into SS pulses to support beam scanning. Other system information such as remaining minimum system information (RMSI), system information block (SIB), and other system information (OSI) can be transmitted on the physical downlink shared channel (PDSCH) in certain subframes. For example, for mmW, an SS block can be transmitted up to 64 times and up to 64 different beam directions can be transmitted. Up to 64 transmissions of SS blocks are called SS pulse sets. SS blocks in an SS pulse set are transmitted in the same frequency region, while SS blocks in different SS pulse sets can be transmitted at different frequency locations.

[0074] In some cases, two or more slave entities (e.g., UEs) may communicate with each other using sidelink signals. Practical applications of such sidelink communications may include public safety, proximity services, UE-to-network relay, vehicle-to-vehicle (V2V) communications, Internet of Everything (IoE) communications, IoT communications, mission-critical grids, and / or various other suitable applications. Generally, a sidelink signal may refer to a signal transmitted from one slave entity (e.g., UE1) to another slave entity (e.g., UE2) without relaying the communication through a scheduling entity (e.g., UE or BS), even though the scheduling entity may be used for scheduling and / or control purposes. In some examples, licensed spectrum may be used to transmit sidelink signals (unlike wireless local area networks that typically use unlicensed spectrum).

[0075] The UE may operate in various radio resource configurations, including a configuration associated with sending a pilot using a dedicated set of resources (e.g., a radio resource control (RRC) dedicated state, etc.) or a configuration associated with sending a pilot using a common set of resources (e.g., an RRC common state, etc.). When operating in the RRC dedicated state, the UE may select a dedicated set of resources for sending a pilot signal to the network. When operating in the RRC common state, the UE may select a common set of resources for sending a pilot signal to the network. In either case, the pilot signal sent by the UE may be received by one or more network access devices, such as one or DUs, or a portion thereof. Each receiving network access device may be configured to receive and measure pilot signals transmitted on a common set of resources, and also receive and measure pilot signals transmitted on a dedicated set of resources allocated to the UE, the network access device being a member of the network access device monitoring set of the UE. One or more receiving network access devices, or (multiple) receiving CUs to which the network access device sends a measurement of a pilot signal, may use the measurement to identify a serving cell of the UE, or to initiate a change of a serving cell for one or more UEs.

[0076] Example QCL Signaling

[0077] In many cases, it may be important for a user equipment (UE) to understand which assumptions it may make on channels corresponding to different transmissions. For example, a UE may need to know which reference signals (RS) it may use to estimate the channel in order to decode a transmitted signal (e.g., a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH)). It may also be important for the UE to be able to report relevant channel state information (CSI) to the BS (gNB) for scheduling, link adaptation and / or beam management purposes. In New Radio (NR), the concepts of Quasi Co-Location (QCL) and Transmission Configuration Indicator (TCI) status are used to convey information about these assumptions.

[0078] The QCL assumption is typically defined based on channel characteristics. According to the 3rd Generation Partnership Project (3GPP) TS 38.214, "two antenna ports are said to be quasi-co-located if properties of the channel over which a symbol on one antenna port is conveyed can be inferred from the channel over which a symbol on the other antenna port is conveyed." Different reference signals may be considered to be quasi-co-located ("QCL'd") if a receiver (e.g., UE) can apply channel properties determined by detecting a first reference signal to assist in detecting a second reference signal. TCI states typically include configurations such as QCL relationships between downlink (DL) RS and PDSCH demodulation reference signal (DMRS) ports in a CSI-RS set.

[0079] In some cases, the UE can configure up to M TCI states. The configuration of the M TCI states can be implemented via high-layer signaling, and the UE can decode the PDSCH based on the detected PDCCH with downlink control information (DCI) indicating one of the TCI states. For example, a specific TCI state can be indicated by an N-bit DCI field for the PDSCH. Each configured TCI state can include an RS set TCI-RS-SetConfig, indicating different QCL assumptions between certain source signals and target signals.

[0080] In certain deployments, techniques are used to provide QCL signaling for RSs and channels across scenarios involving multiple cells, such as coordinated multi-point (CoMP) scenarios where multiple transmit receive points (TRPs) or integrated access and backhaul (IAB) nodes each have their own cell ID.

[0081] Figure 7 An example of how the RS associated with the TCI state can be configured via radio resource control (RRC) signaling is shown. In some cases, the QCL information and / or type may depend on other information or be a function of other information. For example, the QCL type indicated to the UE may be based on a higher layer parameter QCL type and may take one or a combination of the following types:

[0082] QCL type A: {Doppler shift, Doppler spread, average delay, delay spread},

[0083] QCL type B: {Doppler shift, Doppler spread},

[0084] QCL Type C: {average delay, Doppler shift}, and

[0085] QCL type D: {spatial RX parameters},

[0086] The spatial QCL assumption (QCL type D) may be used to help the UE select a simulated RX beam (e.g., during a beam management procedure). For example, a synchronization signal block (SSB) resource indicator may indicate that the same beam used for a previous reference signal should be used for a subsequent transmission.

[0087] like Figure 7 As shown, the TCI state can indicate which RSs are QCL'd and the QCL type. The TCI state can also indicate ServCellIndex, which is a short identifier used to identify the serving cell, such as the primary cell (PCell) or secondary cell (Scell) in a carrier aggregation (CA) deployment. A value of 0 for this field can indicate a PCell, while a previously assigned SCellIndex can apply to the SCell.

[0088] Figure 8 An example of association of DL reference signals with corresponding QCL types that may be indicated by TCI-RS-SetConfig according to aspects of the present disclosure is shown.

[0089] exist Figure 8 In the example of , the source RS can be indicated in the top block and can be associated with the target signal indicated in the bottom block. In this context, the target signal generally refers to a signal whose channel properties can be inferred by measuring those channel properties of the associated source signal. As described above, the UE can use the source RS to determine various channel parameters, depending on the associated QCL type, and use these various channel properties (determined based on the source RS) to process the target signal. The target RS does not necessarily have to be the DMRS of the PDSCH, but can be any other RS, such as PUSCH DMRS, CSIRS, TRS or SRS.

[0090] As shown, each TCI-RS-SetConfig contains parameters. For example, these parameters can configure the QCL relationship between the RS in the RS set and the DMRS port group of the PDSCH. The RS set can contain references to one or two DL RSs and the associated QCL type of each one configured by the higher layer parameter QCL type.

[0091] like Figure 8 As shown, for the case of two DL RSs, the QCL type can take multiple arrangements. For example, the QCL type can be different, whether the reference is to the same DL RS or different DL RS. In the example shown, the SSB can be associated with a Class C QCL for P-TRS, while the CSI-RS for beam management (CSIRS-BM) can be associated with a Class D QCL.

[0092] When a TCI state identification (ID) set for PDSCH is activated by a media access control (MAC) control element (CE), at least for a set of component carriers (CCs) / bandwidth parts (BWPs) of the same frequency band, when the applicable CC list is indicated by RRC signaling, the same TCI state ID set may be applied to all BWPs in the indicated CCs. In certain aspects, this feature may support inter-band carrier aggregation (CA) (i.e., using a single MAC CE to activate the same PDSCH TCI state ID set for multiple CCs / BWPs).

[0093] In some aspects, a list of applicable frequency bands for a feature may be indicated and may be based on UE capabilities. In addition, this functionality may be applicable to single transmit receive point (TRP) or multiple TRP situations.

[0094] Various combinations of CCs can be configured through RRC and related UE capabilities.

[0095] In order to activate TCI states simultaneously across multiple CCs / BWPs, up to two CC lists can be configured per UE's RRC. The application list can be determined by the indicated CC in the MAC CE (and applied to all CCs in the list containing the indicated CC). In some aspects, the list can be restricted so that the UE does not expect overlapping CCs in multiple RRC-configured CC lists.

[0096] Example of updating energy saving behavior simultaneously across multiple frequency resource sets

[0097] Certain aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for applying energy-saving techniques. More specifically, common energy-saving behaviors may be applied across multiple frequency resource sets (eg, component carriers (CCs) and / or bandwidth parts (BWPs)).

[0098] For example, for group CC based beam updating, each CC group may share the same analog beamformer, resulting in each CC in the group sharing the same radio frequency (RF) front end (e.g., generally defined as everything between the antenna and the digital baseband system). Therefore, it would be advantageous to have each CC in a CC group configured with or otherwise have the same sleep behavior. However, currently, some power saving techniques are applied per CC and / or per BWP (as opposed to applying power saving behavior across multiple sets of frequency resources). Inter-slot scheduling adaptation is an example of a power saving technique applied per CC / BWP.

[0099] One of the main design goals of NR is to support a variety of applications, including low-latency data transmission. To achieve this, various features are introduced, including dynamic scheduling timing (denoted by K0, K1, and K2), which determine the delay between different paired control and data transmissions. K0 is the offset between the downlink (DL) time slot where the physical downlink control channel (PDCCH) for downlink scheduling (i.e., the PDCCH carrying downlink control information (DCI)) is received and the DL time slot where the physical downlink shared channel (PDSCH) data is scheduled. K1 is the offset between the DL time slot where data is scheduled on the PDSCH and the UL time slot where the hybrid automatic repeat request (HARQ) acknowledgement (ACK) / negative acknowledgement (NACK) feedback for the scheduled PDSCH data needs to be sent. K2 is the offset between the DL time slot where the PDCCH for uplink (UL) scheduling (i.e., the PDCCH carrying DCI) is received and the UL time slot where UL data needs to be sent on the PUSCH.

[0100] Therefore, in one example, two CCs, CC0 and CC1, sharing the same RF front end may have different minimum applicable K0 scheduling delay values. Therefore, the K0 value of CC0 may be 0, and the K0 value of CC1 may be 2. Because the K0 value of CC0 is set to 0, the RF may not be shut down.

[0101] In another case, the K0 value may be restricted. For example, a single DCI may indicate a minimum K0 value of 2 for all CCs in a group; however, such restriction may reduce efficiency and reliability.

[0102] In order to adopt a minimum applicable value K0 (or K2) of scheduling delay for an active DL (or UL) BWP of a carrier transmitting PDSCH (or physical uplink shared channel (PUSCH)), various features can be supported. In some aspects, there may be one or two radio resource control (RRC) configuration values ​​for restrictions on the active TDRA table, and each RRC configuration can be each BWP. In some examples where there are one or two RRC configuration values ​​for BWP, a 1-bit indication can be used to indicate one RRC configuration value from two candidate values. In some examples where there is only one RRC configuration value, the 1-bit indication can further indicate whether there is a restriction (or no restriction) on the active TDRA table.

[0103] In some aspects, a 1-bit indication in DCI format 1_1 or format 0_1 ​​may be used to jointly determine the minimum applicable K0 for the active DL BWP and the minimum applicable K2 for the active UL BWP, which are to be applied at least after applying a delay.

[0104] However, aspects of the present disclosure may enhance energy saving and simplify signaling (with reduced overhead) by allowing common energy saving behaviors to be applied across multiple sets of frequency resources (ie, application across multiple CCs and / or BWPs).

[0105] Fig. 9 Flowchart illustrating example operations 900 for wireless communication in accordance with certain aspects of the present disclosure. Operations 900 may be performed, for example, by a UE (e.g., UE 120 in wireless communication network 100). For example, Figure 1 The UE 120 may perform operation 900 to enhance energy saving. Operation 900 may be a supplementary operation of operation 1000 performed by the UE to a network entity (e.g., BS 110 in the wireless communication network 100). Operation 900 may be implemented as a processor (e.g., Figure 4 In addition, the software components may be executed and run on the processor 480 of the device. Figure 4 The antenna 452 of the UE sends and receives signals through the UE in operation 900. In some aspects, the transmission and / or reception of signals by the UE can be implemented via a bus interface of one or more processors (e.g., the processor 480) to obtain and / or output signals.

[0106] Operations 900 may begin at block 902 by obtaining, by a UE, signaling from a network entity indicating a common power saving behavior. At block 904, the UE applies the common power saving behavior on a plurality of sets of frequency resources.

[0107] Fig.101000 for wireless communication in accordance with certain aspects of the present disclosure. Operations 10000 may be performed, for example, by a network entity (e.g., BS 110 in wireless communication network 1000). Operations 1000 may be complementary operations to operations 900 performed by the network entity on a UE (e.g., UE 120 in wireless communication network 100). Operations 1000 may be implemented as a processor on one or more processors (e.g., Figure 4 In addition, the software components may be executed and run on the processor 440 of the processor. Figure 4 The antenna 434 of the source node is used to implement the sending and receiving of signals by the network entity in operation 1000. In some aspects, the signal transmission and / or reception of the source node can be implemented via a bus interface of one or more processors (e.g., processor 440) to obtain and / or output signals.

[0108] At block 1002, operations 1000 may begin by a network entity providing signaling to a UE indicating a common power saving behavior. At block 1004, the network entity communicates with the UE on a plurality of sets of frequency resources in accordance with the common power saving behavior.

[0109] In this way, common energy saving behaviors can be updated simultaneously on multiple BWP / CCs. This update can be provided to multiple BWP / CCs via a single indication to reduce overhead to update energy saving behaviors across multiple BWP / CCs.

[0110] As used herein, the term common power saving behavior may include any number of various power saving features applied across multiple sets of frequency resources (eg, CCs and / or BWPs).

[0111] In some aspects, applying common energy-saving behaviors may include applying a common wake-up / sleep time pattern across multiple frequency resource sets. In normal operation, the UE may be awake all the time to monitor the PDCCH for each subframe; however, this may cause power consumption issues on the UE side. For example, if the UE is awake when there is no data to be transmitted from the network entity, the UE may be wasting energy. Therefore, a discontinuous reception (DRX) mechanism is introduced to allow the UE to enter a sleep mode for a certain period of time and wake up in a subsequent period of time. Therefore, the common wake-up / sleep time pattern may be a common DRX ON / OFF pattern applied across all CCs and / or BWPs.

[0112] In some aspects, signaling indicating common energy-saving behaviors may include a common time pattern for PDCCH monitoring, and a corresponding search space / CORESET configuration. Thus, the PDCCH monitoring time pattern and the corresponding search space / CORESET configuration may be applied across multiple frequency resource sets. In some examples, a joint (common) monitoring pattern across multiple CCs may explicitly indicate a common monitoring time pattern across multiple CCs.

[0113] In some aspects, frequency resource sets may have different parameter sets. The parameter set corresponds to a subcarrier spacing (SCS) in the frequency domain. In order to support a wide range of deployment scenarios, from large cells with carrier frequencies below 1 GHz to millimeter wave deployments with very wide spectrum allocations, NR supports flexible parameter sets with a range of SCSs based on scaling of the baseline SCS of 15 kHz. Different parameter sets can be defined by scaling the reference subcarrier spacing by an integer N. Therefore, in aspects where frequency resources (e.g., CC / BWP) have different parameter sets, a common monitoring time mode may have different / same monitoring opportunity durations across multiple frequency resource sets with the same start time. In some examples, at least one of the monitoring opportunity start time or the monitoring opportunity duration may be indicated based on multiple symbols in the reference parameter set. An orthogonal frequency division multiplexing (OFDM) symbol may specify the first symbol of each control resource set (CORESET) monitoring opportunity in a time slot. For example, a common monitoring tuning mode may start a reference parameter set (e.g., SCS=30 KHz) every X time slots. In addition, the monitoring opportunity can be relative to the SCS (e.g., each SCS has a monitoring opportunity duration of 2 codewords) or absolute (e.g., for a reference SCS, the monitoring opportunity duration is equal to 2 codewords). In order to ensure that the monitoring of PDCCH transmissions for all CCs is common, a relative or absolute monitoring opportunity duration can be indicated based on the codewords in the reference parameter set.

[0114] In some aspects, common energy saving behaviors may include / involve a common sleep or non-sleep state. Thus, a common sleep or non-sleep state may be applied across multiple frequency resource sets. For example, when in a common sleep state, PDCCH monitoring may be turned off on an activated cell (i.e., the UE may not monitor PDCCH transmissions on multiple frequency resource sets).

[0115] In some aspects, common energy saving behavior may include / involve common limits on one or more spatial parameters. Thus, common limits on one or more spatial parameters may be applied across multiple sets of frequency resources. In some examples, the limits may involve a common maximum number of DL / UL multiple-input multiple-output (MIMO) layers. In some examples, the limits may involve a common maximum number of DL / UL active beams (e.g., indicated via an active transmission configuration indicator (TCI) state / spatial relationship).

[0116] In some aspects, common energy-saving behaviors may include / involve a common minimum scheduling offset between DCI and scheduled DL / UL signals. Thus, a common minimum scheduling offset may be applied across multiple frequency resource sets. For example, a common minimum scheduling may involve a minimum K0 or K2 value for a PDSCH, an access point (AP) channel state information reference signal (CSI-RS), a PUSCH, or an AP sounding reference signal (SRS). In some examples where a CC has different parameter sets, a common minimum K0 or K2 value may be signaled via a common absolute value (e.g., a K0 or K2 value for a reference parameter set like SCS=30KHz), and the value of the reference parameter set may be converted to a corresponding K0 or K2 value for a different parameter set. Alternatively, in some examples where a CC has different parameter sets, different minimum K0 or K2 values ​​may be signaled for different parameter sets (e.g., different K0 or K2 values ​​in different parameter sets selected so that they will result in the same absolute scheduling delay).

[0117] Fig.11 A call flow diagram illustrating example signaling for simultaneously updating energy-saving behaviors across multiple sets of frequency resources in accordance with certain aspects of the present disclosure is shown. Fig.11 As shown, at 1104, UE 120 may obtain signaling indicating common energy saving behaviors from network entity 110. In some examples, the signaling may be via RRC signaling. In some examples, the signaling may be via a medium access control (MAC) control element (CE). In some examples, the signaling may be via DCI.

[0118] In some aspects, the network entity 110 may provide signaling to the UE 120 in response to a request received from the UE 120. Thus, at 1102, the UE 120 may send a request for common energy saving behavior to the network entity 110 (e.g., in uplink control information (UCI) or MAC-CE). Thus, the network entity 110 may send signaling to the UE 120 in response to the received request at 1104.

[0119] At 1106, UE 120 may apply a common energy saving behavior on multiple sets of frequency resources. In some examples, the set of frequency resources (e.g., BWP / CC) on which the common energy saving behavior is to be applied may be indicated via RRC signaling, MAC-CE, or DCI. The signaling may be the same or different from the signaling used to indicate the common energy saving behavior.

[0120] For example, as described above, multiple CC lists may be configured by the RRC of each UE, and the CC indicated in the MAC-CE or DCI may determine to which list the common energy saving behavior is applied. In addition, the indicated CC may also signal the common energy saving behavior. In other words, the common energy saving behavior may be applied to all CCs in the list, including the CC indicated in the MAC-CE or DCI.

[0121] In some aspects, multiple CC lists used for CC-based beam updates may be reused for common power saving behavior updates.

[0122] In some aspects, simultaneous updating of energy conservation behaviors across multiple sets of frequency resources (e.g., BWP / CC) may be enabled through explicit signaling. In some aspects, simultaneous updating of energy conservation behaviors across multiple sets of frequency resources may be enabled based on whether any CC lists are configured.

[0123] After simultaneously updating the energy saving behavior across the multiple sets of frequency resources, at 1108, the network entity 110 and the UE 120 may communicate on the multiple sets of frequency resources according to the common energy saving behavior.

A processor may also be implemented as a combination of computing devices, such as a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.

[0166] If implemented in hardware, an example hardware configuration may include a processing system in a wireless node. The processing system may be implemented using a bus architecture. Depending on the specific application and overall design constraints of the processing system, the bus may include any number of interconnecting buses and bridges. The bus may link various circuits together, including a processor, a machine-readable medium, and a bus interface. The bus interface may be used to connect a network adapter, etc., to the processing system via the bus. The network adapter may be used to implement the signal processing functions of the PHY layer.

Those skilled in the art will recognize how to best implement the described functionality for the processing system depending on the specific application and the overall design constraints imposed on the entire system.

[0167] If implemented in software, each function may be stored on or transmitted through a computer-readable medium as one or more instructions or codes. Software should be broadly interpreted as instructions, data, or any combination thereof, whether referring to software, firmware, middleware, microcode, hardware description language, or other. Computer-readable media include both computer storage media and communication media, including any media that facilitate the transfer of computer programs from one place to another. The processor may be responsible for managing the bus and general processing, including executing software modules stored on a machine-readable storage medium. A computer-readable storage medium may be coupled to a processor so that the processor can read information from the storage medium and write information to the storage medium. Alternatively, the storage medium may be integrated into the processor. For example, a machine-readable medium may include a transmission line, a carrier modulated by data, and / or a computer-readable storage medium, on which instructions separated from a wireless node are stored, all of which may be accessed by the processor through a bus interface. Alternatively or additionally, a machine-readable medium or any portion thereof may be integrated into a processor, such as a cache and / or a general register file. Examples of machine-readable storage media may include, for example, RAM (random access memory), flash memory, phase change memory, ROM (read only memory), PROM (programmable read only memory), EPROM (erasable programmable read only memory), EEPROM (electrically erasable programmable read only memory), registers, magnetic disks, optical disks, hard drives, or any other suitable storage media, or any combination thereof. The machine-readable medium may be embodied in a computer program product.

[0168] A software module may include one or more instructions and may be distributed across several different code segments, between different programs, and across multiple storage media. A computer-readable medium may include multiple software modules. A software module includes instructions that, when executed by a device such as a processor, cause a processing system to perform various functions. A software module may include a sending module and a receiving module. Each software module may reside in a single storage device or may be distributed across multiple storage devices. For example, when a triggering event occurs, a software module may be loaded from a hard drive into a RAM. During the execution of a software module, a processor may load some instructions into a cache to increase access speed. One or more cache lines may then be loaded into a general register file for execution by the processor. When the function of a software module is mentioned hereinafter, it should be understood that the function is implemented by the processor when an instruction from the software module is executed.

[0169] Any connection is also properly referred to as a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, an optical cable, a twisted pair, a digital subscriber line (DSL), or a wireless technology such as infrared, radio, and microwave, then the coaxial cable, optical cable, twisted pair, DSL, or a wireless technology such as infrared, radio, and microwave is included in the definition of medium. Disks and discs as used herein include compact discs (CDs), laser discs, optical discs, digital versatile discs (DVDs), floppy disks, and blue-ray discs, where disks often reproduce data magnetically, while optical discs reproduce data optically with lasers. Therefore, in some aspects, a computer-readable medium may include a non-transitory computer-readable medium (e.g., a tangible medium). The phrase "computer-readable medium" refers to a non-transient propagation signal. In addition, for other aspects, a computer-readable medium may include a temporary computer-readable medium (e.g., a signal). The above combination should also be included in the scope of computer-readable media.
