[0004] The following relates generally to wireless communications and, more particularly, to resource management for low latency wireless communications.

[0005] Wireless multiple access technology has been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, and even global level. An example telecommunication standard is Long Term Evolution (LTE). LTE is designed to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. LTE can use Orthogonal Frequency Division Multiple Access (OFDMA) on the downlink (DL), Single Carrier Frequency Division Multiple Access (SC-FDMA) on the uplink (UL), and Multiple Input Multiple Output (MIMO) antenna technology.

[0006] In some examples, a wireless multiple access communication system may include several base stations, each base station supporting communication of multiple communication devices (also referred to as user equipment (UE)) simultaneously. In an LTE or advanced LTE (LTE-A) network, a set of one or more base stations may define an evolved B node (eNB). In other examples (e.g., in a next generation new radio (NR) or 5G network), a wireless multiple access communication system may include several smart radio heads (RHs) in communication with several access node controllers (ANCs), wherein a set of one or more RHs in communication with the ANC defines a base station (e.g., an eNB or gNB). A base station may communicate with a set of UEs on a DL channel (i.e., for transmission from a base station to a UE) and a UL channel (i.e., for transmission from a UE to a base station).

[0007] Base stations in some LTE or NR deployments may use transmission time intervals (TTIs) of different lengths to transmit to one or more UEs, which may be reduced in length relative to some TTIs (e.g., legacy or LTE TTIs). Such reduced-length TTIs may be referred to as shortened TTIs (sTTIs) and may support some low-latency services, which provide low latency and high reliability for wireless transmission of low-latency services. sTTIs may be a subset of one or more subframes corresponding to legacy TTI subframes. The base station may allocate transmission resources for sTTIs to UEs, which may include time resources and frequency resources. In some cases, the reliability of sTTI transmissions may be enhanced relative to other non-low-latency transmissions, and therefore sTTI transmissions may be more sensitive to interference.

[0008] Overview

[0009] The described technology relates to a method, system, device or apparatus for supporting improved resource management for low latency communications. In general, the described technology provides low latency transmission time interval (TTI) transmission, which can reduce the possibility of experiencing interference from one or more adjacent transmitters. A base station can be configured for two or more resource sets for two or more wireless transmission sets, wherein a low latency transmission can use all or part of one of these resource sets to transmit in one wireless transmission set. In some cases, a resource set that can be used for low latency transmission can be associated with a power parameter set, which provides a reduced transmission power relative to one or more of the other resource sets.

[0027] The described technology relates to improved methods, systems, devices or apparatuses supporting resource management for low latency communications, which may provide resource sets with different power parameters to enhance the reliability of some low latency transmissions. Some transmissions may use shortened transmission time intervals TTI (sTTI) for uplink or downlink transmissions, wherein the length of sTTI may be shorter than the old long term evolution (LTE) subframe or 1ms transmission time interval (TTI). In some cases, a base station may configure a first resource set with a first power parameter set, and a second resource set with a second power parameter set reduced relative to the first power parameter set. The base station may coordinate with one or more neighboring base stations so that each base station configures a second resource set with a second power parameter set. Low latency transmissions may be transmitted using the second resource set, and may accordingly have reduced inter-cell interference from transmissions from neighboring base stations relative to potential inter-cell interference of transmissions using the first resource set. The second resource set may include one or more subbands of available frequency resources, one or more subsets of time resources, or a combination thereof.

[0028] Although the various examples provided herein provide for a second resource set having a second power parameter set that is reduced relative to a first power parameter set, the principles provided herein are also applicable to situations where the second resource set has power parameters that are increased relative to the first power parameter set, and the techniques discussed herein may be used to provide a second resource set having power parameters that are increased relative to the first power parameter set.

[0029] Resources allocated for sTTI transmissions may be used for uplink and / or downlink communications (referred to as low latency communications) that are relatively latency-sensitive relative to communications that may be relatively latency-insensitive, such as enhanced mobile broadband (eMBB) transmissions that may use 1 ms (or legacy LTE) TTI durations. In some cases, the sTTI duration may correspond, for example, to one slot of a radio subframe, or to two or three orthogonal frequency division multiplexing (OFDM) symbols; and the 1 ms TTI duration may correspond to the duration of a 1 ms subframe.

[0030] Such low latency communications can be used in systems that can support multiple different services for data communications, for example. Such different services can be selected depending on the nature of the communication. For example, communications that require low latency and high reliability (sometimes referred to as mission-critical (MiCr) communications) can be served by using lower latency services using sTTI (e.g., ultra-reliable low latency communications (URLLC) services). Accordingly, communications with higher delay tolerance can be served by providing relatively high throughput services with slightly higher latency (such as mobile broadband services (e.g., eMBB services) using 1ms TTI). In other examples, it is possible to communicate with user equipment (UE) that incorporates other devices (e.g., meters, vehicles, appliances, machines, etc.), and machine type communication (MTC) services (e.g., large-scale MTC (mMTC)) can be used for such communications. In some cases, different services (e.g., eMBB, URLLC, mMTC) can have different TTIs, different subcarrier (or frequency modulation) intervals, and different cyclic prefixes.

[0031] The present disclosure describes various techniques with reference to 4G networks (e.g., LTE networks) and next generation networks (e.g., 5G networks or NR networks) designed to support features such as high bandwidth operation, more dynamic subframe / time slot types, and self-contained subframe / time slot types in which hybrid ARQ (HARQ) feedback for a subframe / time slot can be transmitted before the end of the subframe / time slot. However, such techniques can be used in any system in which TTIs of different lengths can be transmitted in a wireless communication system.

[0032] The techniques described in various examples provide for identifying a first power parameter set associated with a first resource set for a first wireless transmission set, the first wireless transmission set having a first duration TTI, which may be a 1 ms TTI. Signaling may be provided from a base station to a UE, which may indicate a second resource set for at least a first subset of a second sTTI wireless transmission set. The second resource set may be associated with a second power parameter set that provides a reduced power relative to the first power parameter set. A transmitter (such as a UE or a base station) may transmit the first wireless transmission set using the first resource set according to the first power parameter set, and transmit at least a first subset of the second wireless transmission set using the second resource set according to the second power parameter set.

[0033] In some cases, transmissions in the second transmission set using resources of the second resource set may experience a reduced likelihood or amount of inter-cell interference and, therefore, have a higher likelihood of successful reception at the receiver. Thus, techniques as discussed herein may provide relatively high reliability, which may help achieve a 10 ms period of time for a 32-byte packet as targeted in some 4G and 5G systems. -5 The reliability of the error rate.

[0034] Various aspects of the present disclosure are initially described in the context of a wireless communication system. Various sTTI structures and resource sets are subsequently described. Various aspects of the present disclosure are further illustrated by and described with reference to device diagrams, system diagrams, and flow diagrams related to resource management for low latency wireless communications.

[0035] Figure 1 An example of a wireless communication system 100 that supports resource management for low latency wireless communications in accordance with various aspects of the present disclosure is illustrated. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 may be an LTE (or Advanced LTE (LTE-A)) network, or a New Radio (NR) network. In some cases, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (i.e., mission-critical or URLLC) communications, low latency communications, and communications with low-cost and low-complexity devices. The wireless communication system 100 may provide wireless transmissions in which sTTI structures and resource power management may allow for higher reliability sTTI transmissions.

[0036] The base station 105 may communicate wirelessly with the UE 115 via one or more base station antennas. Each base station 105 may provide communication coverage for a corresponding geographic coverage area 110. The communication link 125 shown in the wireless communication system 100 may include an uplink (UL) transmission from the UE 115 to the base station 105, or a downlink (DL) transmission from the base station 105 to the UE 115. Control information and data may be multiplexed on an uplink channel or a downlink according to various techniques. Control information and data may be multiplexed on a downlink channel, for example, using a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. In some examples, the control information transmitted during the TTI of the downlink channel may be distributed in a cascaded manner between different control regions (e.g., between a common control region and one or more control regions that vary depending on the UE).

[0037] UE 115 may be dispersed throughout the wireless communication system 100, and each UE 115 may be stationary or mobile. UE 115 may also be referred to as a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable term. UE 115 may also be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless phone, a personal electronic device, a handheld device, a personal computer, a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, an MTC device, an appliance, an automobile, and the like.

[0038] In some cases, UE 115 may also be able to communicate directly with other UEs (e.g., using peer-to-peer (P2P) or device-to-device (D2D) protocols). One or more UEs in a group of UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of a cell. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the cell, or may not be able to receive transmissions from the base station 105 for other reasons. In some cases, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, wherein each UE 115 transmits to each other UE 115 in the group. In some cases, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed independently of the base station 105.

[0039] Some UEs 115 (such as MTC or IoT devices) may be low-cost or low-complexity devices and may provide automated communication between machines, i.e., machine-to-machine (M2M) communication. M2M or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station without human intervention. For example, M2M or MTC may refer to communication from a device that is integrated with a sensor or meter to measure or capture information and relay the information to a central server or application, which may utilize the information or present the information to a human interacting with the program or application. Some UEs 115 may be designed to collect information or implement automated behavior of a machine. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0040] In some cases, MTC devices may operate at a reduced peak rate using half-duplex (one-way) communications. MTC devices may also be configured to enter a power-saving "deep sleep" mode when not engaged in active communications. In some cases, MTC or IoT devices may be designed to support mission-critical functions, and the wireless communication system may be configured to provide ultra-reliable communications for these functions.

[0041] Each base station 105 can communicate with the core network 130 and with each other. For example, the base station 105 can be connected to the core network 130 via a backhaul link 132 (e.g., S1, etc.). The base stations 105 can communicate with each other directly or indirectly (e.g., through the core network 130) on a backhaul link 134 (e.g., X2, etc.). The base station 105 can perform radio configuration and scheduling for communication with the UE 115, or can operate under the control of a base station controller (not shown). In some examples, the base station 105 can be a macro cell, a small cell, a hotspot, etc. The base station 105 can also be referred to as an evolved B node (eNB) 105.

[0042] The base station 105 may be connected to the core network 130 via an S1 interface. The core network may be an evolved packet core (EPC), which may include at least one mobile management entity (MME), at least one S-GW, and at least one P-GW. The MME may be a control node that handles signaling between the UE 115 and the EPC. All user Internet Protocol (IP) packets may be delivered via the S-GW, which itself may be connected to the P-GW. The P-GW may provide IP address allocation and other functions. The P-GW may be connected to a network operator IP service. The operator IP service may include the Internet, an intranet, an IP multimedia subsystem (IMS), and a packet switched (PS) streaming service (PSS).

[0043] The core network 130 may provide user authentication, access authorization, tracking, IP connectivity, and other access, routing, or mobility functions. At least some network devices (such as base stations 105) may include subcomponents, such as access network entities, which may be examples of access node controllers (ANCs). Each access network entity may communicate with a number of UEs 115 via one or more access network transport entities, each of which may be an example of a smart radio head or a transmit / receive point (TRP). In some configurations, the various functions of each access network entity or base station 105 may be distributed across various network devices (e.g., radio heads and access network controllers) or merged into a single network device (e.g., base station 105).

[0044] The wireless communication system 100 can operate using a frequency band from 700MHz to 2600MHz (2.6GHz) in the ultra-high frequency (UHF) frequency division, but in some cases a wireless local area network (WLAN) network can use frequencies up to 4GHz. Since the wavelength is in the range from about 1 decimeter to 1 meter long, this division can also be referred to as a decimeter band. UHF waves can be mainly propagated by line of sight and can be blocked by buildings and environmental features. However, these waves can fully penetrate walls to provide services to UE115 located indoors. Compared with the transmission of smaller frequencies (and longer waves) using the high frequency (HF) or very high frequency (VHF) part of the spectrum, the transmission of UHF waves is characterized by smaller antennas and shorter ranges (e.g., less than 100km). In some cases, the wireless communication system 100 can also utilize the extremely high frequency (EHF) part of the spectrum (e.g., from 30GHz to 300GHz). Since the wavelength is in the range from about 1 millimeter to 1 centimeter long, this division can also be referred to as a millimeter band. Thus, EHF antennas may be even smaller and more closely spaced than UHF antennas. In some cases, this may facilitate the use of antenna arrays within UE 115 (eg, for directional beamforming).

[0045] In some cases, the wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer can be based on IP. In some cases, the radio link control (RLC) layer can perform packet segmentation and reorganization to communicate on the logical channel. The media access control (MAC) layer can perform priority handling and multiplex the logical channel into a transport channel. The MAC layer can also use HARQ to provide retransmission of the MAC layer, thereby improving link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration and maintenance of the RRC connection of the radio bearer that supports user plane data between the UE 115 and the network device or the core network 130. In the physical (PHY) layer, the transport channel can be mapped to the physical channel.

[0046] The time interval in LTE or NR can be used in a basic time unit (which can be a sampling period T s =1 / 30,720,000 seconds). Time resources can be expressed in multiples of 10ms (T f =307200T s ) radio frames, which can be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame may include 10 1ms subframes numbered from 0 to 9. The subframe may be further divided into two 0.5ms time slots, where each time slot contains 6 or 7 modulation code element periods (depending on the length of the cyclic prefix added before each code element). Excluding the cyclic prefix, each code element contains 2048 sampling periods. In some cases, the subframe can be the minimum scheduling unit, also known as TTI. In other cases, the TTI can be shorter than the subframe (e.g., sTTI) or can be dynamically selected (e.g., in a short TTI burst or in a selected component carrier using a short TTI).

[0047] A resource element may include one symbol period and one subcarrier (e.g., 15KHz frequency range). A resource block may include 12 consecutive subcarriers in the frequency domain, and for a normal cyclic prefix in each OFDM symbol, 7 consecutive OFDM symbols in the time domain (1 slot), or 84 resource elements. The number of bits carried by each resource element may depend on the modulation scheme (the symbol configuration that may be selected during each symbol period, which may be referred to as a modulation and coding scheme (MCS)). Therefore, the more resource blocks a UE receives and the higher the modulation scheme, the higher the data rate may be.

[0048] The wireless communication system 100 may support operation on multiple cells or carriers, a feature that may be referred to as carrier aggregation (CA) or multi-carrier operation. A carrier may also be referred to as a component carrier (CC), layer, channel, etc. The terms "carrier," "component carrier," "cell," and "channel" may be used interchangeably herein. A UE 115 may be configured with multiple downlink CCs and one or more uplink CCs for carrier aggregation. Carrier aggregation may be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0049] In some cases, the wireless communication system 100 may utilize an enhanced component carrier (eCC). An eCC may be characterized by one or more features, including: wider bandwidth, shorter symbol duration, shorter TTI, and modified control channel configuration. In some cases, an eCC may be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple serving cells have suboptimal or non-ideal backhaul links). An eCC may also be configured to be used in an unlicensed spectrum or a shared spectrum (where more than one operator is allowed to use the spectrum). An eCC characterized by a wide bandwidth may include one or more segments that may be utilized by a UE 115 that is not able to monitor the entire bandwidth or prefers to use a limited bandwidth (e.g., to save power). In some cases, an eCC may utilize a symbol duration different from that of other CCs, which may include using a reduced symbol duration compared to the symbol duration of other CCs. A shorter symbol duration may be associated with an increased subcarrier spacing. A TTI in an eCC may include one or more symbols. In some cases, the TTI duration (i.e., the number of symbols in a TTI) may be variable.

[0050] In some cases, the wireless system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless system 100 may adopt LTE license assisted access (LTE-LAA) or LTE unlicensed (LTE U) radio access technology or NR technology (NR-SS) in an unlicensed band (such as, 5GHz industrial, scientific and medical (ISM) band). When operating in an unlicensed radio frequency spectrum band, wireless devices (such as base stations 105 and UE 115) may adopt a listen-before-talk (LBT) procedure to ensure that the channel is clear before transmitting data. In some cases, operations in unlicensed bands can be based on carrier aggregation (CA) configuration in coordination with CCs operating in licensed bands. Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, or both. Duplexing in unlicensed spectrum may be based on FDD, TDD, or a combination of both.

[0051] As indicated above, in some cases, the base station 105 and the UE 115 may use two or more resource sets for wireless transmissions. In some cases, a first power parameter set may be associated with the first wireless resource set, and a second power parameter set may be associated with the second wireless resource set, the second power parameter set providing a reduced transmit power relative to the first power parameter set. Neighboring base stations may coordinate so that each base station configures a second resource set with reduced power transmission relative to one or more other resource sets. Low latency transmissions may be transmitted using the second resource set and may therefore have reduced inter-cell interference from transmissions from neighboring base stations relative to potential inter-cell interference for transmissions using the first resource set. The second resource set may include one or more subbands of available frequency resources, one or more subsets of time resources, or a combination thereof.

[0052] Figure 2 An example of a wireless communication system 200 supporting resource management for low latency wireless communication according to aspects of the present disclosure is illustrated. The wireless communication system 200 includes a first base station 105-a, a second base station 105-b, a first UE 115-a and a second UE 115-b, which may be reference Figure 1 Examples of various aspects of the base station 105 or UE 115 are described. Figure 2 In the example of , the wireless communication system 200 may operate according to a radio access technology (RAT) such as LTE, 5G, or NR RAT, although the techniques described herein may be applied to any RAT and to systems that may use two or more different RATs concurrently.

[0053] The first base station 105-a may communicate with a first UE 115-a and one or more other UEs within a first geographic coverage area 110-a of the first base station 105-a over an uplink carrier 205 and a downlink carrier 215. The second base station 105-b may communicate with a second UE 115-b and one or more other UEs within a second geographic coverage area 110-b of the second base station 105-b over a link 220. The link 220 may include uplink and downlink carriers that may carry transmissions using 1 ms TTIs and sTTIs in a manner similar to that discussed with respect to the uplink carrier 205 and the downlink carrier 215.

[0054] In some examples, the first base station 105-a may allocate resources for communicating with each UE on the uplink carrier 205 and the downlink carrier 215. For example, the first base station 105-a may allocate uplink subframes 210 in the uplink carrier 205 for uplink transmissions from the first UE 115-a, and one or more uplink subframes 210 may correspond to a legacy LTE TTI of 1 ms. In this example, the uplink subframes 210 may include a first uplink subframe 210-a, a second uplink subframe 210-b, and a third uplink subframe 210-c. Each of the uplink subframes 210 may include two time slots, where each time slot may have 7 OFDM symbols for a normal cyclic prefix. In this example, a first time slot (time slot 0) 225 and a second time slot (time slot 1) 230 may be included in the first subframe 210-a. Similarly, the first base station 105-a may allocate downlink subframes 218 in the downlink carrier 215 for downlink transmissions to the first UE 115-a. In this example, the downlink subframes 218 may include a first downlink subframe 218-a, a second downlink subframe 218-b, and a third downlink subframe 218-c.

[0055] As indicated above, in the uplink of a low latency system, different sTTI lengths may be used for transmissions on the uplink carrier 205. For example, two-symbol sTTIs and one-slot sTTI durations may be supported for physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmissions (or shortened PUCCH (sPUCCH) and shortened PUSCH (sPUSCH) transmissions). Thus, within a first slot 225 or a second slot 230, there may be multiple sTTIs (such as a first sTTI (TTI-0) 235, a second sTTI (TTI-1) 240, and a third sTTI (TTI-2) 245), each of which may have two or three OFDM symbol durations. This TTI duration may also be applied to a downlink subframe 218 transmitted on a downlink carrier 215.

[0056] When using two-symbol sTTI, in some cases, it may be desirable to have a fixed sTTI structure, where the sTTI boundaries are located within or aligned with the slot boundaries (such as the boundaries of the first slot 225 or the second slot 230), which may be referred to as slot-aligned sTTIs. As discussed above, when using normal CP, 7 symbols are included in each slot 225-230, and thus for slot-aligned sTTIs, each slot may include 3 sTTIs. In some cases, one of the sTTIs may be configured as a three-symbol TTI in order to efficiently utilize each symbol of each slot. In such cases, different modes may be considered, such as having the three-symbol TTI located at the end of the slot 225-230, or at the beginning of the slot 225-230. When using two-symbol sTTIs or a combination of two-symbol and three-symbol sTTIs, such sTTIs may be referred to as 2-symbol sTTIs. When using an sTTI with a duration corresponding to one slot, such sTTI may be referred to as a slotted sTTI or a slot-aligned sTTI. When using a TTI with a duration corresponding to a subframe, such TTI may be referred to as a 1ms TTI or a legacy TTI.

[0057] In some examples, a 2-symbol downlink sTTI may use a first symbol pattern {3, 2, 2, 2, 2, 3} for two slots within a subframe boundary, or a second symbol pattern {2, 3, 2, 2, 2, 3} may be used for such transmissions. In some cases, the mode to be used may be indicated in a legacy control channel such as the Physical Control Format Indicator Channel (PCFICH), where a legacy control region of 1 or 3 symbols indicates the first mode and a legacy control region of 2 symbols indicates the second mode. For uplink transmissions for 2-symbol sTTI transmissions, one of the following two modes will also be specified: {3, 2, 2, 2, 2, 3} or {2, 2, 3, 2, 2, 3}.

[0058] As indicated above, in some cases, power parameters for uplink and downlink resources may be managed to provide different resource sets using different power parameters. Such different power parameters may allow for enhanced interference management, which may help to enhance the reliability of certain transmissions, such as low latency transmissions that may have relatively stringent reliability targets. In some cases, resources may be managed for low latency transmissions in the form of puncturing non-low latency transmissions (e.g., legacy 1-ms traffic, legacy ultra-low latency traffic with lower reliability targets, etc.), reserving resources for high reliability and low latency operations (e.g., via reserved frequency domain and / or time domain resources), overlaying with other traffic (e.g., legacy 1-ms traffic), or a combination thereof.

[0059] In some examples, the first base station 105-a and the second base station 105-b can coordinate subband-related power management for DL ​​and / or UL, which is potentially combined with sTTI subsets or codeword subsets. In some cases, a downlink or uplink transmission may have an available bandwidth for transmission (e.g., 20MHz), which may be divided into several subbands (e.g., 5MHz subbands). In this case, different subbands may be configured with different power parameters. For example, a 20MHz bandwidth may be divided into 4 subbands, each of which is 5MHz, providing SB1, SB2, SB3, and SB4. In this example, SB1 and SB2 may be managed using conventional power, SB3 may be managed using reduced power (e.g., 10dB lower than SB1 and SB2), and SB4 may be retained (no transmission). One or more cell-specific reference signal (CRS) transmissions may be transmitted at conventional power across all subbands. In some examples, the subband and power parameters may be indicated by signaling that varies from UE to UE or from cell to cell. In some examples, the traffic-to-pilot ratio (TPR) may be determined based on the type of pilot or reference signal transmitted and a power parameter associated with the resource. For example, for CRS-based downlink transmissions, the UE 115 may be instructed or determine the TPR (i.e., the ratio of the physical data shared channel (PDSCH) to the CRS) based on restricted power management in different subbands. For demodulation reference signal (DM-RS)-based downlink transmissions, the UE 115 may assume the same TPR (i.e., the ratio of PDSCH to DM-RS) across all subbands, even though the absolute power of each subband may be different. In other words, both DM-RS and PDSCH have the same amount of restriction in the power management of a given subband.

[0060] In some examples, as a supplement or replacement for frequency resources, power restrictions on certain resources by power parameters associated with resources can be used for time resources. For example, a resource set can be identified as including only certain sTTIs or (all) OFDM symbols. In other cases, both time and frequency resources can be identified for different resource sets. For example, SB1 may have a first power parameter set for the first sTTI and a second power parameter set for the second sTTI. In some cases, the power restriction associated with the power parameter set can be specified by specifying a maximum transmission power reduced per subband, a power offset compared to an unrestricted subband, or a separate open-loop (or closed-loop) power control parameter set (relative to the parameters for subbands under no restrictions). In some examples, if a reduced maximum transmission power is used, the transmission can be transmitted using only resources with the same power parameters for efficient reception purposes. For example, it may not be desirable to have a PUSCH transmission with some RBs in the first subband under a first power restriction and other RBs in the second subband under a second power restriction. In other examples, if power offsets between different power parameter sets are used, a single uplink channel transmission may have some RBs in a first subband under a first constraint and other RBs in a second subband under a second constraint. Similarly, if different resource sets include time resources, power constraints for one or more resource sets may be applied only in certain sTTIs or (symbols) rather than in all sTTIs / symbols of a subband in a subframe. In a further example, both time and frequency resources may be identified for different resource sets, resulting in sTTI-dependent subband power constraints, such as discussed above (e.g., SB1 has a first power level in a first sTTI, but a second power level different from the first power level in a second sTTI).

[0061] In some cases, the first base station 105-a may use beamforming to transmit the beam 250 in the desired direction, and the second base station 105-b may use beamforming to transmit the second beam 255 in the desired direction. In some cases, the first base station 105-a and the second base station 105-b may coordinate one or more parameters in the second power parameter set to coordinate the beam directions of the first base station 105-a and the second base station 105-b to different beam directions.

[0062] In some examples, the first base station 105-a and the second base station 105-b can coordinate different power parameters for different resource sets through backhaul coordination. Such backhaul coordination may include frequency domain resource reservation for low latency transmission, such as by using RB blocks as the granularity for reservation. Additionally or alternatively, such backhaul coordination may include time domain resource reservation, such as by using 1 codeword or 2 codeword sTTI as a unit for reservation. In some cases, the power parameter may be applied to resource sets for both uplink and downlink resources, and may be a pair of downlink and uplink resources in each link direction, which can help ensure that the possibility of inter-cell interference is reduced for each transmission on resources with power-limited power parameters. In some cases, interference coordination may also take the form of reduced downlink transmit power and / or reduced uplink transmit power in some RBs and / or some sTTIs or codewords. In some cases, a power spectral density (PSD) may be identified across different resource sets, and power parameters for the first resource set and the second resource set may be selected to achieve the identified PSD (e.g., the power for some frequency resources may be reduced relative to other frequency resources to achieve the desired power spectral density). In some further examples, the UEs 115 may each provide periodic channel state information (CSI) reports, and the base station 105 may receive the CSI reports and identify that certain resources are experiencing increased interference or interference exceeding a threshold level. In such a case, the base station 105 may add the identified resources to a resource set with a power parameter that provides a reduced transmission power in order to reduce potential interference at neighboring base stations 105. In some cases, the base stations 105 may coordinate with each other to add such resources to a resource set with a reduced power level.

[0063] Figure 3 An example of a sTTI structure 300 that supports resource management for low latency wireless communications in accordance with various aspects of the present disclosure is illustrated. The sTTI structure 300 can be used for communications between a UE and a base station, such as regarding Figure 1 and 2 As discussed. Various different configurations of sTTI can be implemented, where the sTTI can be arranged to be aligned with a subframe or a time slot.

[0064] In this example, two downlink sTTI configurations and two uplink sTTI configurations may be used for low latency downlink transmissions, although the techniques described herein are also applicable to other sTTI configurations that may be implemented. A first downlink sTTI configuration is illustrated in downlink sTTI 305, which may be used for downlink transmissions from a base station to a UE and may be transmitted using the pattern {3, 2, 2, 2, 2, 3} as discussed above. In this example, for downlink sTTI 305, according to the first downlink sTTI configuration, sTTI-0 may be a three-symbol sTTI, sTTI-1 to sTTI-4 may be two-symbol sTTIs, and sTTI-5 may be a three-symbol sTTI. A second downlink sTTI configuration is illustrated in downlink sTTI 310, which may have a pattern {2, 3, 2, 2, 2, 3} as discussed above. In this example, for the downlink sTTI 310 with the second downlink configuration, sTTI-0 can be a two-symbol sTTI, sTTI-1 can be a three-symbol sTTI, sTTI-2 to sTTI-4 can be two-symbol sTTIs, and sTTI-5 can be a three-symbol sTTI.

[0065] In addition, in this example, different configurations for uplink sTTI are explained. In this example, an uplink sTTI 315 with a first configuration (configuration-A) may be used for uplink transmission from a UE to a base station. In this example, an uplink sTTI 315 may have a pattern {3,2,2,2,2,3} as discussed above. In this example, for an uplink sTTI 315 with uplink configuration-A, sTTI-0 may be a three-symbol sTTI, sTTI-1 to sTTI-4 may be two-symbol sTTIs, and sTTI-5 may be a three-symbol sTTI. In this example, a second configuration (configuration-B) of an uplink sTTI 320 may have a pattern {2,2,3,2,2,3} as discussed above. In this example, for the uplink sTTI 320 with uplink configuration-B, sTTI-0 and sTTI-1 can be two-symbol sTTIs, sTTI-2 can be three-symbol sTTIs, sTTI-3 and sTTI-4 can be two-symbol sTTIs, and sTTI-5 can be three-symbol sTTIs.

[0066] As discussed above, using Figure 3Low latency transmissions of sTTI structures such as the sTTI structure explained in may have relatively high reliability targets. In some examples, the transmission power used for certain wireless transmission resources may be limited to help reduce interference between different cellular cells, and such wireless transmission resources may be selected for transmission of low latency communications. Although the use of power-limited resources can help reduce interference to low latency transmissions, other non-power-limited resources may also be used for such low latency transmissions, and the base station may allocate resources from any resource set (power-limited or non-power-limited) based on various factors (such as current traffic conditions, current interference levels for different resources (e.g., derived from CSI reports), availability of different resources, etc.).

[0067] Figure 4 An example of a set of wireless resources 400 that supports resource management for low latency wireless communications in accordance with various aspects of the present disclosure is illustrated. The wireless resources 400 may be used for communications between a UE and a base station, such as regarding Figure 1 and 2 discussed.

[0068] In this example, the wireless resources 400 may include subframes that may be configured with sTTIs according to the pattern {3, 2, 2, 2, 2, 3}, although this example is provided for discussion purposes and the techniques discussed herein may be applied to any sTTI pattern, or to wireless resources that are not configured according to an sTTI pattern. The subframe may have frequency resources spanning four subbands, namely subband-1 405, subband-2 410, subband-3 415, and subband-4 420. The wireless resources 400 may include resource sets that may have different associated power parameters. In this example, different time and frequency resources may have different power parameters, although resources with different power parameters may include only different time resources or only different frequency resources, as discussed above. In this example, all time resources of subband-3 415 may be a first power restricted resource subset, sTTI-1 of subband-1 405 may be a second power restricted resource subset, sTTI-2 of subband-2 410 may be a third power restricted resource subset, sTTI-3 of subband-2 410 may be a fourth power restricted resource subset, and sTTI-5 of subband-4 may be a fifth power restricted resource subset. In some cases, the first through fifth power restricted resource subsets may be grouped together as a power restricted resource set. In other cases, one or more of the first through fifth power restricted resource subsets may be grouped into different power restricted resource sets, which may have different amounts of power restrictions applied (including no power restrictions that may reserve certain resources). Radio resources other than the first through fifth power limited resource subsets may not have any power limitations applied and may include transmissions having power levels determined according to unrestricted power parameters, while the power limited resources may have an offset or specified reduced power from the unrestricted power parameters, such as discussed above.

[0069] Figure 5 An example of a process flow 500 for supporting resource management for low latency wireless communications in accordance with aspects of the present disclosure is illustrated. The process flow 500 may include a base station 105-c and a UE 115-c, which may be referenced Figure 1-2 Examples of corresponding devices described. The base station 105-c and the UE 115-c may establish a connection 505 according to a connection establishment technique for a wireless communication system.

[0070] At block 510, the base station 105-c may identify power parameters for the first set of resources and the second set of resources. Such power parameters may be identified based on a service that may be provided by the base station 105-c, such as a URLLC service or an eMBB service. In some cases, the base station 105-c may identify a first unrestricted set of power parameters for non-low latency or non-high reliability transmissions for the first set of resources, and may identify a second restricted set of power parameters for low latency and high reliability transmissions for the second set of resources. In some cases, the second restricted set of power parameters may reduce the power used for the second set of resources in order to mitigate potential interference with one or more other base stations. The base station 105-c transmits configuration information 515 to the UE 115-c that may indicate the power parameters. .

[0071] At block 520, the UE 115-c may identify power parameters for the first and second resource sets. In some cases, the UE 115-c may identify a first power parameter set and apply a reduced power or a power offset to determine a second power parameter set. In some cases, the configuration information 515 may indicate each of the first and second power parameter sets.

[0072] At block 525, the base station 105-c may allocate resources for the first and second wireless transmission sets. Such resource allocations may include allocating resources in the first resource set for non-low latency transmissions and allocating resources in the second resource set for low latency transmissions. In some cases, resources within the second resource set may be allocated for non-low latency transmissions, which may be transmitted using restricted power parameters in the second power parameter set. The resource allocation(s) may be communicated to the UE 115-c in downlink control information (DCI) 530.

[0073] At block 535, the UE 115-c may receive the DCI 530 and determine the allocated resources for uplink transmissions. Depending on the resource set that includes the allocated resources, the UE 115-c may apply a corresponding set of power parameters as indicated at block 540 and may transmit uplink transmission(s) 545. At block 550, the base station 105-c may perform received signal processing (e.g., HARQ processing, etc.).

[0074] Figure 6 An example of a process flow 600 for supporting resource management for low latency wireless communications in accordance with aspects of the present disclosure is illustrated. The process flow 600 may include a first base station 105-d, a second base station 105-e, and a UE 115-d, which may be referenced to Figure 1-2 Examples of corresponding devices described.

[0075] At block 605, the first base station 105-d may identify services and traffic for different services. The services may be identified based on data to be transmitted to one or more served UEs, established services for one or more UEs, or one or more requests for services from one or more UEs. The services may include, for example, one or more low-latency services, one or more non-low-latency services, or a combination thereof.

[0076] At block 615, the second base station 105-d may also identify the services and the traffic for the different services in a similar manner.

[0077] In box 610, the first base station 105-d can identify resources for potential use by different wireless transmission sets. In some cases, the first base station can identify a first resource set and a second resource set, which can be identified as resource sets that can have different power parameters applied to wireless transmissions using the resources. In some cases, it may be preferred to transmit certain wireless services, such as, for example, a low latency and high reliability service (e.g., a URLLC service) using a second resource set that can have power parameters that are power-restricted, and a 1ms TTI service (e.g., an eMBB service) using a first resource set that can have power parameters that are not power-restricted. In box 615, the second base station 105-e can identify resources for potential use by different wireless transmission sets in a similar manner.

[0078] At block 625, the first base station 105-d and the second base station 105-e may coordinate resource sets with reduced power parameters to mitigate inter-cell interference. Such coordination may be performed by identifying different resource sets and identifying power parameters for each of these resource sets. In some examples, such coordination may be performed via backhaul coordination over a backhaul link (e.g., an X2 link).

[0079] In this example, the second base station 105-e may provide configuration information 630 to the UE 115-d. The configuration information 630 may include, for example, an indication of different resource sets and an indication of power parameters for at least one of the resource sets. In some cases, the configuration information 630 may include a power parameter for each resource set.

[0080] At block 635, the UE 115-d may identify power parameters for the first and second sets of resources. The UE 115-d may identify the power parameters based on the indication of the first set of power parameters and apply a power difference or offset to the first set of power parameters to obtain the second set of power parameters. In some cases, the UE 115-d may identify the power parameters for the first and second sets of resources based on signaling indicating the power parameters.

[0081] Such power parameters may be identified based on a service that may be provided by the second base station 105-e, such as a URLLC service or an eMBB service. In some cases, the second base station 105-e may identify a first non-restricted set of power parameters for a first set of resources for non-low latency or non-high reliability transmissions, and may identify a second restricted set of power parameters for a second set of resources for low latency and high reliability transmissions. In some cases, the second restricted set of power parameters may reduce the power used for the second set of resources in order to mitigate potential interference with one or more other base stations. After identifying the power parameters, the second base station 105-e and the UE 115-d may perform as described with reference to Figure 5 Similar operations as described.

[0087] The transmitter 720 may transmit signals generated by other components of the device. In some examples, the transmitter 720 may be co-located with the receiver 710 in a transceiver module. For example, the transmitter 720 may be as described in reference to Fig.10 Examples of aspects of the described transceiver 1035. The transmitter 720 may include a single antenna, or it may include a collection of antennas.

[0088] The transmitter 720 may transmit a first set of wireless transmissions using a first set of resources according to a first set of power parameters and transmit at least a first subset of a second set of wireless transmissions using a second set of resources according to a second set of power parameters.

[0092] The power parameter identification component 825 may identify a first power parameter set associated with a first resource set for a first wireless transmission set, the first wireless transmission set having a first duration TTI. In some cases, signaling indicating a second power parameter set may be received. In some cases, the power parameter identification component 825 may identify a third power parameter set associated with a second time resource subset. In some cases, identifying the second power parameter set includes one or more of: identifying a maximum transmit power of the first power parameter set and applying a reduction to the maximum transmit power for the second power parameter set; identifying a first transmit power of the first power parameter set and applying an offset to the first transmit power to provide a reduced second transmit power of the second power parameter set; identifying a first open-loop or closed-loop power control parameter set for the first resource set, identifying a second open-loop or closed-loop power control parameter set for the second resource set, and applying the second open-loop or closed-loop power control parameter set to the second resource set; or identifying a maximum PSD for the first resource set and the second resource set and selecting a first transmit power for the first resource set and a second transmit power for the second resource set to provide a PSD within the maximum PSD.

For example, the transmitter 820 may be as described in reference to Fig.10 Examples of aspects of the described transceiver 1035. The transmitter 820 may include a single antenna, or it may include a collection of antennas.

[0095] Fig. 9 A block diagram 900 of a UE resource manager 915 supporting resource management for low latency wireless communications according to aspects of the present disclosure is shown. The UE resource manager 915 may be a reference Figure 7 , 8 10 and 11. The UE resource manager 915 may include a power parameter identification component 920, a resource allocation component 925, a subband identification component 930, a time resource identification component 935, and a pilot signal component 940. Each of these modules can communicate with each other directly or indirectly (e.g., via one or more buses).

[0096] The power parameter identification component 920 may identify a first power parameter set associated with a first resource set for a first wireless transmission set, the first wireless transmission set having a first duration TTI. In some cases, signaling indicating a second power parameter set may be received. In some cases, the power parameter identification component 920 may identify a third power parameter set associated with a second time resource subset. In some cases, identifying the second power parameter set includes one or more of: identifying a maximum transmit power of the first power parameter set and applying a reduction to the maximum transmit power for the second power parameter set; identifying a first transmit power of the first power parameter set and applying an offset to the first transmit power to provide a reduced second transmit power of the second power parameter set; identifying a first open-loop or closed-loop power control parameter set for the first resource set, identifying a second open-loop or closed-loop power control parameter set for the second resource set, and applying the second open-loop or closed-loop power control parameter set to the second resource set; or identifying a maximum PSD for the first resource set and the second resource set and selecting a first transmit power for the first resource set and a second transmit power for the second resource set to provide a PSD within the maximum PSD.

[0185] In some examples, aspects from two or more of the described methods may be combined.It should be noted that the described methods are merely example implementations and that the operations of the described methods may be rearranged or otherwise modified such that other implementations are possible.

[0186] The technology described herein can be used for various wireless communication systems, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), SC-FDMA and other systems. The terms "system" and "network" are often used interchangeably. A CDMA system can implement radio technologies such as CDMA2000, Universal Terrestrial Radio Access (UTRA), etc. CDMA2000 covers IS-2000, IS-95 and IS-856 standards. IS-2000 versions are often referred to as CDMA2000 1X, 1X, etc. IS-856 (TIA-856) is often referred to as CDMA2000 1xEV-DO, High Rate Packet Data (HRPD), etc. UTRA includes Wideband CDMA (WCDMA) and other CDMA variants. A TDMA system can implement radio technologies such as Global System for Mobile Communications (GSM).

[0187] OFDMA systems can implement radio technologies such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and Advanced LTE (LTE-A) are UMTS versions that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, NR, 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). The technology described herein can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. Although aspects of an LTE or NR system may be described for example purposes, and LTE or NR terminology is used in much of the description above, the techniques described herein may also be applicable to applications other than LTE or NR applications.

[0188] In LTE / LTE-A networks (including such networks described herein), the term evolved Node B (eNB) may be generally used to describe a base station. One or more wireless communication systems described herein may include heterogeneous LTE / LTE-A or NR networks, in which different types of evolved Node Bs (eNBs) provide coverage for various geographic regions. For example, each eNB, gNB, or base station may provide communication coverage for a macro cell, a small cell, or other types of cells. Depending on the context, the term "cell" may be used to describe a base station, a carrier or component carrier associated with a base station, or a coverage area (e.g., sector, etc.) of a carrier or base station.

[0189] A base station may include or may be referred to by those skilled in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a B node, an evolved B node (eNB), a next generation B node (gNB), a home B node, a home evolved B node, or some other suitable term. The geographic coverage area of ​​a base station may be divided into sectors that constitute only a portion of the coverage area. One or more wireless communication systems described herein may include different types of base stations (e.g., macro or small cell base stations). The UE described herein may be able to communicate with various types of base stations and network equipment (including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.). There may be overlapping geographic coverage areas of different technologies.

[0190] A macro cell generally covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs with service subscriptions to a network provider. Compared to a macro cell, a small cell is a low-power base station that may operate in the same or different (e.g., licensed, unlicensed, etc.) frequency band as a macro cell. According to various examples, a small cell may include a pico cell, a femto cell, and a micro cell. A pico cell, for example, may cover a smaller geographic area and may allow unrestricted access by UEs with service subscriptions to a network provider. A femto cell may also cover a smaller geographic area (e.g., a residence) and may provide restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs of users in the residence, etc.). An eNB for a macro cell may be referred to as a macro eNB. An eNB for a small cell may be referred to as a small cell eNB, a pico eNB, a femto eNB, or a home eNB. An eNB may support one or more (e.g., two, three, four, etc.) cells (e.g., component carriers).

[0191] One or more wireless communication systems described herein may support synchronous or asynchronous operation. For synchronous operation, each base station may have similar frame timing, and transmissions from different base stations may be approximately aligned in time. For asynchronous operation, each base station may have different frame timing, and transmissions from different base stations may not be aligned in time. The techniques described herein may be used for synchronous or asynchronous operation.

[0192] Downlink transmissions described herein may also be referred to as forward link transmissions, and uplink transmissions may also be referred to as reverse link transmissions. Each communication link described herein includes, for example, a reference to Figure 1 and 2 The wireless communication systems 100 and 200 described may include one or more carriers, wherein each carrier may be a signal composed of multiple subcarriers (eg, waveform signals of different frequencies).

[0193] The descriptions set forth herein in conjunction with the accompanying drawings describe example configurations and do not represent all examples that may be implemented or that fall within the scope of the claims. The term "exemplary" as used herein means "used as an example, instance, or illustration" and does not mean "better than" or "better than other examples." This detailed description includes specific details to provide an understanding of the described techniques. However, these techniques may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form to avoid obscuring the concepts of the described examples.

[0194] In the accompanying drawings, similar components or features may have the same reference number. In addition, various components of the same type may be distinguished by following the reference number with a dash and a second reference number that distinguishes between the similar components. If only the first reference number is used in the specification, the description may apply to any of the similar components having the same first reference number regardless of the second reference number.

[0195] The information and signals described herein may be represented using any of a variety of different techniques and technologies. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be mentioned throughout the above description may be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, optical fields or optical particles, or any combination thereof.

[0196] The various illustrative blocks and modules described in conjunction with the disclosure herein may be implemented or executed with a general purpose processor, a DSP, an ASIC, an FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but in an alternative, the processor may be any conventional processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices (e.g., 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).

[0197] The functions described herein may be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, each function may be stored on a computer-readable medium or transmitted therefrom as one or more instructions or codes. Other examples and implementations fall within the scope and spirit of the present disclosure and the appended claims. For example, due to the nature of software, the above functions may be implemented using software executed by a processor, hardware, firmware, hard wiring, or any combination thereof. The features that implement the functions may be physically located in various locations, including being distributed so that the various parts of the functions are implemented at different physical locations. As used herein (including in the claims), the term "and / or" used in the enumeration of two or more items means that any one of the listed items may be adopted alone, or any combination of two or more listed items may be adopted. For example, if a composition is described as comprising components A, B, and / or C, the composition may comprise only A; only B; only C; a combination of A and B; a combination of A and C; a combination of B and C; or a combination of A, B, and C. Likewise, as used herein (including in the claims), "or" used in a list of items (e.g., a list of items followed by a phrase such as "at least one of" or "one or more of") indicates an inclusive list, such that, for example, a phrase reciting "at least one of" a list of items refers to any combination of those items, including single members. As an example, "at least one of A, B, or C" is intended to cover: A, B, C, AB, AC, BC, and ABC, as well as any combination with multiple identical elements (e.g., AA, AAA, AAB, AAC, ABB, ACC, BB, BBB, BBC, CC, and CCC, or any other ordering of A, B, and C).

[0198] As used herein, the phrase "based on" should not be interpreted as referring to a closed set of conditions. For example, an exemplary feature described as "based on condition A" can be based on both condition A and condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "based at least in part on".

[0199] Computer readable medium includes both non-transient computer storage medium and communication medium, and it includes any medium that facilitates computer program to transfer from one place to another place.Non-transient storage medium can be any available medium that can be accessed by general or special-purpose computer.As an example and not limitation, non-transient computer readable medium can include RAM, ROM, electrically erasable programmable read-only memory (EEPROM), compact disk (CD) ROM or other optical disk storage, disk storage or other magnetic storage device, or can be used to carry or store instruction or data structure form of desired program code means and can be accessed by general or special-purpose computer or general or special-purpose processor any other non-transient medium.Any connection is also properly referred to as computer readable medium.For example, if software is transmitted from website, server or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) or wireless technology such as infrared, radio and microwave, then this coaxial cable, fiber optic cable, twisted pair, DSL or wireless technology such as infrared, radio and microwave are just included in the definition of medium. Disk and disc as used herein include CDs, laser discs, optical discs, digital versatile discs (DVDs), floppy disks, and Blu-ray discs, where disks usually reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above are also included within the scope of computer-readable media.
