Abstract

Time domain resource allocation is facilitated for a physical downlink shared channel. For instance, a physical downlink shared channel associated with a mobile device can be configured via a broadcast channel, and a data structure associated with the physical downlink shared channel corresponding to a physical downlink control channel can also be configured. The configured data structure can be sent to the mobile device to be utilized for physical downlink shared channel transmissions between the wireless network device and the mobile device. Additionally, the time domain resources can be allocated by transmitting a physical downlink shared channel transmission to the mobile device based on a condition associated with a radio resource control connection being determined to not have been satisfied.

Description

RELATED APPLICATION

The subject patent application is a continuation of, and claims priority to, U.S. patent application Ser. No. 15/967,131, filed Apr. 30, 2018, and entitled “PHYSICAL DOWNLINK SHARED CHANNEL TIME DOMAIN RESOURCE ALLOCATION FOR 5G OR OTHER NEXT GENERATION NETWORK,” the entirety of which application is hereby incorporated by reference herein.

TECHNICAL FIELD

This disclosure relates generally to facilitating physical downlink shared channel time domain resource allocation. For example, this disclosure relates to facilitating physical downlink shared channel time domain resource allocation based on a slot configuration for a 5G, or other next generation network, air interface.

BACKGROUND

5^thgeneration (5G) wireless systems represent a next major phase of mobile telecommunications standards beyond the current telecommunications standards of 4^thgeneration (4G). Rather than faster peak Internet connection speeds, 5G planning aims at higher capacity than current 4G, allowing a higher number of mobile broadband users per area unit, and allowing consumption of higher or unlimited data quantities. This would enable a large portion of the population to stream high-definition media many hours per day with their mobile devices, when out of reach of wireless fidelity hotspots. 5G research and development also aims at improved support of machine-to-machine communication, also known as the Internet of things, aiming at lower cost, lower battery consumption, and lower latency than 4G equipment.
The above-described background relating to facilitating physical downlink shared channel time domain resource allocation is merely intended to provide a contextual overview of some current issues, and is not intended to be exhaustive. Other contextual information may become further apparent upon review of the following detailed description.

The term article of manufacture, as used herein, is intended to encompass a computer program accessible from any computer-readable device, carrier, or media, including a non-transitory machine-readable storage medium.
It should be noted that although various aspects and embodiments have been described herein in the context of 5G, Universal Mobile Telecommunications System (UMTS), and/or Long Term Evolution (LTE), or other next generation networks, the disclosed aspects are not limited to 5G, a UMTS implementation, and/or an LTE implementation as the techniques can also be applied in 3G, 4G or LTE systems. For example, aspects or features of the disclosed embodiments can be exploited in substantially any wireless communication technology. Such wireless communication technologies can include UMTS, Code Division Multiple Access (CDMA), Wi-Fi, Worldwide Interoperability for Microwave Access (WiMAX), General Packet Radio Service (GPRS), Enhanced GPRS, Third Generation Partnership Project (3GPP), LTE, Third Generation Partnership Project 2 (3GPP2) Ultra Mobile Broadband (UMB), High Speed Packet Access (HSPA), Evolved High Speed Packet Access (HSPA+), High-Speed Downlink Packet Access (HSDPA), High-Speed Uplink Packet Access (HSUPA), Zigbee, or another IEEE 802.XX technology. Additionally, substantially all aspects disclosed herein can be exploited in legacy telecommunication technologies.
Described herein are systems, methods, articles of manufacture, and other embodiments or implementations that can facilitate physical downlink shared channel time domain resource allocation for a 5G network. Facilitating physical downlink shared channel time domain resource allocation for a 5G network can be implemented in connection with any type of device with a connection to the communications network (e.g., a mobile handset, a computer, a handheld device, etc.) any Internet of things (JOT) device (e.g., toaster, coffee maker, blinds, music players, speakers, etc.), and/or any connected vehicles (cars, airplanes, space rockets, and/or other at least partially automated vehicles (e.g., drones)). In some embodiments the non-limiting term user equipment (UE) is used. It can refer to any type of wireless device that communicates with a radio network node in a cellular or mobile communication system. Examples of UE are target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communication, PDA, Tablet, mobile terminals, smart phone, laptop embedded equipped (LEE), laptop mounted equipment (LME), USB dongles etc. Note that the terms element, elements and antenna ports can be interchangeably used but carry the same meaning in this disclosure. The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g. interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception.
In some embodiments the non-limiting term radio network node or simply network node is used. It can refer to any type of network node that serves UE is connected to other network nodes or network elements or any radio node from where UE receives a signal. Examples of radio network nodes are Node B, base station (BS), multi-standard radio (MSR) node such as MSR BS, eNode B, network controller, radio network controller (RNC), base station controller (BSC), relay, donor node controlling relay, base transceiver station (BTS), access point (AP), transmission points, transmission nodes, RRU, RRH, nodes in distributed antenna system (DAS) etc.
Cloud radio access networks (RAN) can enable the implementation of concepts such as software-defined network (SDN) and network function virtualization (NFV) in 5G networks. This disclosure can facilitate a generic channel state information framework design for a 5G network. Certain embodiments of this disclosure can comprise an SDN controller that can control routing of traffic within the network and between the network and traffic destinations. The SDN controller can be merged with the 5G network architecture to enable service deliveries via open application programming interfaces (“APIs”) and move the network core towards an all internet protocol (“IP”), cloud based, and software driven telecommunications network. The SDN controller can work with, or take the place of policy and charging rules function (“PCRF”) network elements so that policies such as quality of service and traffic management and routing can be synchronized and managed end to end.
To meet the huge demand for data centric applications, 4G standards can be applied 5G, also called new radio (NR) access. 5G networks can comprise the following: data rates of several tens of megabits per second supported for tens of thousands of users; 1 gigabit per second can be offered simultaneously to tens of workers on the same office floor; several hundreds of thousands of simultaneous connections can be supported for massive sensor deployments; spectral efficiency can be enhanced compared to 4G; improved coverage; enhanced signaling efficiency; and reduced latency compared to LTE. In multicarrier system such as orthogonal frequency-division multiplexing (OFDM), each subcarrier can occupy bandwidth (e.g., subcarrier spacing). If the carriers use the same bandwidth spacing, then it can be considered a single numerology. However, if the carriers occupy different bandwidth and/or spacing, then it can be considered a multiple numerology.
Downlink reference signals are predefined signals occupying specific resource elements within a downlink time-frequency grid. There are several types of downlink reference signals that can be transmitted in different ways and used for different purposes by a receiving terminal. Channel state information reference signals (CSI-RS) can be used by terminals to acquire channel-state information (CSI) and beam specific information (e.g., beam reference signal received power). In 5G, CSI-RS can be user equipment (UE) specific so it can have a significantly lower time/frequency density. Demodulation reference signals (DM-RS), also sometimes referred to as UE-specific reference signals, can be used by terminals for channel estimation of data channels. The label “UE-specific” relates to the demodulation reference signal being intended for channel estimation by a single terminal. The demodulation reference signal can then be transmitted within the resource blocks assigned for data traffic channel transmission to that terminal. Other than the aforementioned reference signals, there are other reference signals, namely multi-cast broadcast single frequency network (MBSFN) and positioning reference signals that can be used for various purposes.
NR can co-exist with LTE in overlapping spectrum in both normal and MBSFN LTE DL subframes. Thus, it is possible to schedule NR physical downlink shared channel (PDSCH) transmissions in subframes with carrier routing systems (CRS). After a dedicated radio resource control (RRC) connection has been established, the LTE CRS pattern, including the MBSFN subframe configuration, can be known to the UE and the UE can rate match the NR PDSCH around the LTE CRS. Before the UE is configured with a dedicated RRC configuration, NR PDSCH transmissions can be confined to symbols between subsequent CRS transmissions. In MBSFN subframes, these can be OFDM symbols 1-13 for one or two LTE CRS ports and OFDM symbols 2-13, otherwise. Moreover, some OFDM symbols, without CRS, can be reserved for NR physical downlink control channel (PDCCH) transmissions, which cannot be rate matched around LTE CRS. Because NR demodulation reference signals (DMRS) are not expected to collide with LTE CRS, possible NR PDSCH time-domain resource allocations can be restricted when NR and LTE are deployed in an overlapping spectrum.
Consequently, a configuration for PDCCH monitoring and PDSCH mapping can allow the maximum NR control-resource set (CORESET) span of three OFDM symbols for coverage in networks that deploy LTE-NR coexistence. A default PDSCH time-domain resource allocation for NR can be introduced that allows UEs to use before the UE is configured with a dedicated RRC connection. The PDSCH can utilize PDSCH mapping and starts on OFDM symbol number 5 as opposed to OFDM symbol number 4. By moving the PDSCH starting symbol from number 4 to number 5, the NR PDCCH can span up to three OFDM symbols. This can allow the same NR coverage when NR and LTE are deployed in overlapping spectrum compared to NR deployments in a dedicated spectrum. In the below tables, the “S” is the start, and the “L” is the length. Table 1-Table 4 can convey to the UE on which symbols the UE can look for the PDSCH.

These and other embodiments or implementations are described in more detail below with reference to the drawings.
Referring now to FIG. 1, illustrated is an example wireless communication system 100 in accordance with various aspects and embodiments of the subject disclosure. In one or more embodiments, system 100 can comprise one or more user equipment UEs 102. The non-limiting term user equipment can refer to any type of device that can communicate with a network node in a cellular or mobile communication system. A UE can have one or more antenna panels having vertical and horizontal elements. Examples of a UE comprise a target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communications, personal digital assistant (PDA), tablet, mobile terminals, smart phone, laptop mounted equipment (LME), universal serial bus (USB) dongles enabled for mobile communications, a computer having mobile capabilities, a mobile device such as cellular phone, a laptop having laptop embedded equipment (LEE, such as a mobile broadband adapter), a tablet computer having a mobile broadband adapter, a wearable device, a virtual reality (VR) device, a heads-up display (HUD) device, a smart car, a machine-type communication (MTC) device, and the like. User equipment UE 102 can also comprise IOT devices that communicate wirelessly.
In various embodiments, system 100 is or comprises a wireless communication network serviced by one or more wireless communication network providers. In example embodiments, a UE 102 can be communicatively coupled to the wireless communication network via a network node 106. The network node (e.g., network node device) can communicate with user equipment (UE), thus providing connectivity between the UE and the wider cellular network. The UE 102 can send transmission type recommendation data to the network node 106. The transmission type recommendation data can comprise a recommendation to transmit data via a closed loop MIMO mode and/or a rank-1 precoder mode.
A network node can have a cabinet and other protected enclosures, an antenna mast, and multiple antennas for performing various transmission operations (e.g., MIMO operations). Network nodes can serve several cells, also called sectors, depending on the configuration and type of antenna. In example embodiments, the UE 102 can send and/or receive communication data via a wireless link to the network node 106. The dashed arrow lines from the network node 106 to the UE 102 represent downlink (DL) communications and the solid arrow lines from the UE 102 to the network nodes 104 represents an uplink (UL) communication.
System 100 can further include one or more communication service provider networks 108 that facilitate providing wireless communication services to various UEs, including UE 102, via the network node 106 and/or various additional network devices (not shown) included in the one or more communication service provider networks 108. The one or more communication service provider networks 108 can include various types of disparate networks, including but not limited to: cellular networks, femto networks, picocell networks, microcell networks, internet protocol (IP) networks Wi-Fi service networks, broadband service network, enterprise networks, cloud based networks, and the like. For example, in at least one implementation, system 100 can be or include a large scale wireless communication network that spans various geographic areas. According to this implementation, the one or more communication service provider networks 108 can be or include the wireless communication network and/or various additional devices and components of the wireless communication network (e.g., additional network devices and cell, additional UEs, network server devices, etc.). The network node 106 can be connected to the one or more communication service provider networks 108 via one or more backhaul links. For example, the one or more backhaul links can comprise wired link components, such as a T1/E1 phone line, a digital subscriber line (DSL) (e.g., either synchronous or asynchronous), an asymmetric DSL (ADSL), an optical fiber backbone, a coaxial cable, and the like. The one or more backhaul links can also include wireless link components, such as but not limited to, line-of-sight (LOS) or non-LOS links which can include terrestrial air-interfaces or deep space links (e.g., satellite communication links for navigation).
Wireless communication system 100 can employ various cellular systems, technologies, and modulation modes to facilitate wireless radio communications between devices (e.g., the UE 102 and the network node 106). While example embodiments might be described for 5G new radio (NR) systems, the embodiments can be applicable to any radio access technology (RAT) or multi-RAT system where the UE operates using multiple carriers e.g. LTE FDD/TDD, GSM/GERAN, CDMA2000 etc.
For example, system 100 can operate in accordance with global system for mobile communications (GSM), universal mobile telecommunications service (UMTS), long term evolution (LTE), LTE frequency division duplexing (LTE FDD, LTE time division duplexing (TDD), high speed packet access (HSPA), code division multiple access (CDMA), wideband CDMA (WCMDA), CDMA2000, time division multiple access (TDMA), frequency division multiple access (FDMA), multi-carrier code division multiple access (MC-CDMA), single-carrier code division multiple access (SC-CDMA), single-carrier FDMA (SC-FDMA), orthogonal frequency division multiplexing (OFDM), discrete Fourier transform spread OFDM (DFT-spread OFDM) single carrier FDMA (SC-FDMA), Filter bank based multi-carrier (FBMC), zero tail DFT-spread-OFDM (ZT DFT-s-OFDM), generalized frequency division multiplexing (GFDM), fixed mobile convergence (FMC), universal fixed mobile convergence (UFMC), unique word OFDM (UW-OFDM), unique word DFT-spread OFDM (UW DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM, resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like. However, various features and functionalities of system 100 are particularly described wherein the devices (e.g., the UEs 102 and the network device 104) of system 100 are configured to communicate wireless signals using one or more multi carrier modulation schemes, wherein data symbols can be transmitted simultaneously over multiple frequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.). The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g. interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception. Note that some embodiments are also applicable for Multi RAB (radio bearers) on some carriers (that is data plus speech is simultaneously scheduled).
In various embodiments, system 100 can be configured to provide and employ 5G wireless networking features and functionalities. 5G wireless communication networks are expected to fulfill the demand of exponentially increasing data traffic and to allow people and machines to enjoy gigabit data rates with virtually zero latency. Compared to 4G, 5G supports more diverse traffic scenarios. For example, in addition to the various types of data communication between conventional UEs (e.g., phones, smartphones, tablets, PCs, televisions, Internet enabled televisions, etc.) supported by 4G networks, 5G networks can be employed to support data communication between smart cars in association with driverless car environments, as well as machine type communications (MTCs). Considering the drastic different communication needs of these different traffic scenarios, the ability to dynamically configure waveform parameters based on traffic scenarios while retaining the benefits of multi carrier modulation schemes (e.g., OFDM and related schemes) can provide a significant contribution to the high speed/capacity and low latency demands of 5G networks. With waveforms that split the bandwidth into several sub-bands, different types of services can be accommodated in different sub-bands with the most suitable waveform and numerology, leading to an improved spectrum utilization for 5G networks.
To meet the demand for data centric applications, features of proposed 5G networks may comprise: increased peak bit rate (e.g., 20 Gbps), larger data volume per unit area (e.g., high system spectral efficiency—for example about 3.5 times that of spectral efficiency of long term evolution (LTE) systems), high capacity that allows more device connectivity both concurrently and instantaneously, lower battery/power consumption (which reduces energy and consumption costs), better connectivity regardless of the geographic region in which a user is located, a larger numbers of devices, lower infrastructural development costs, and higher reliability of the communications. Thus, 5G networks may allow for: data rates of several tens of megabits per second should be supported for tens of thousands of users, 1 gigabit per second to be offered simultaneously to tens of workers on the same office floor, for example; several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments; improved coverage, enhanced signaling efficiency; reduced latency compared to LTE.
The upcoming 5G access network may utilize higher frequencies (e.g., >6 GHz) to aid in increasing capacity. Currently, much of the millimeter wave (mmWave) spectrum, the band of spectrum between 30 gigahertz (GHz) and 300 GHz is underutilized. The millimeter waves have shorter wavelengths that range from 10 millimeters to 1 millimeter, and these mmWave signals experience severe path loss, penetration loss, and fading. However, the shorter wavelength at mmWave frequencies also allows more antennas to be packed in the same physical dimension, which allows for large-scale spatial multiplexing and highly directional beamforming.
Performance can be improved if both the transmitter and the receiver are equipped with multiple antennas. Multi-antenna techniques can significantly increase the data rates and reliability of a wireless communication system. The use of multiple input multiple output (MIMO) techniques, which was introduced in the third-generation partnership project (3GPP) and has been in use (including with LTE), is a multi-antenna technique that can improve the spectral efficiency of transmissions, thereby significantly boosting the overall data carrying capacity of wireless systems. The use of multiple-input multiple-output (MIMO) techniques can improve mmWave communications, and has been widely recognized a potentially important component for access networks operating in higher frequencies. MIMO can be used for achieving diversity gain, spatial multiplexing gain and beamforming gain. For these reasons, MIMO systems are an important part of the 3rd and 4th generation wireless systems, and are planned for use in 5G systems.
Referring now to FIG. 2, illustrated is an example schematic system block diagram of wireless communication 200 between a base station device and a mobile device according to one or more embodiments.
In one embodiment, the UE 102 can be configured before it communicates with the network. The UE 102 can detect the network node 106 and acquire timing and frequency synchronization. Thus, the network node 106 can send a synchronization signal 202 to the UE 102 prior to sending data over a broadcast channel 204 to configure an NR PDCCH (e.g., downlink control channel 206). The broadcast channel 204 can configure the UE 102 on how to receive the downlink control channel 206. When the downlink control channel 206 schedules the downlink shared channel 208, the UE 102 can determine which signal to use by means of the downlink control channel 206 signaling which row of the table to use. Thus, a default table (e.g., Table 2, Table 4, etc.) can be sent to the UE for the first transmission on the broadcast channel 204. Consequently, a default table can be used during the downlink shared channel 208 transmission, then the payload of the downlink shared channel 208 can reconfigure the table, or if the payload does not reconfigure the table, the UE 102 can continue using the default table. The PDSCH can transmit remaining minimum system information (RMSI). During the first data transmission, the UE can use the default table, then the network can decide whether the UE is to continue using the default table or to use the reconfigured table. The default tables (e.g., Table 2, Table 4, etc.) can then be first configured (as later depicted by FIG. 3), by a payload carried by the PDSCH 208, to use for subsequent PDSCH transmissions (e.g., 214, 220, 224, 228) until a dedicated RRC configuration is established.
Reconfiguration of the default tables (e.g., Table 2, Table 4, etc.) can result in new tables (e.g., Table 1, Table 3, etc.) After a dedicated RRC connection has been established and acknowledged, the UE 102 can either continue to use the tables configured by the PDSCH 208 for PDSCH resource allocation, or, alternatively, the dedicated RRC configuration can provide new tables for PDSCH resource allocation. Similarly, if the PDSCH 208 message does not provide a new table to use for subsequent PDSCH transmissions, the UE 102, can continue to use the default tables to demodulate the PDSCH 208. It should be noted that the table can be reconfigured at PDSCH 208 or at any PDSCH (e.g., 214, 220, 224, 228) at a later point. However, PDCCH 206 is the first chance for the network to configure the table (e.g., uses default table) so PDCCH 206 does not receive a reconfigured table, although PDCCH 206 can reconfigure the table for use at a later point.
Referring now to FIG. 3, illustrated is an example schematic system block diagram of physical downlink shared channel mapping type A 300 according to one or more embodiments.
FIG. 3 depicts a configuration where NR is scheduled in an MBSFN subframe. Tables 1-4, above, tell the UE on which symbols to look for the PDSCH. The the initial block count (from left to right) starts at 0. Thus, for example, block 5 is representative of the 6^thsymbol. To determine the symbol “S”, determine the reference signal (e.g., NR PDSCH DMRS for PDSCH) block number. The length “L” then equals the number of reference signal blocks plus the number of PDSCH blocks. K₀is typically 0, but if it is not 0, then there can be a slot gap between the NRPDCCH and the DMRS.
In 5G, the same spectrum can be used for legacy LTE and for the 5G. Historically, in order use the 5G spectrum, the legacy LTE spectrum can be turned off. However, in 5G, the spectrum can continue to be used for the legacy LTE and to deploy a 5G system on top of the same spectrum. FIG. 3 depicts an OFDM grid with 1 PRB and 14 symbols in the time domain on the horizontal axis and 12 subcarriers on the vertical axis is the frequency domain. The LTE CRS can be transmitted so that the 5G system has to coexist with the LTE CRS, which is why the 5G system does not use the first 2 two symbols. The first symbol that does not carry LTE CRS, for the 5G control system, is the NR PDCCH, then the 5G reference system can use the NR PDSCH DMRS for PDSCH type A.
NR can co-exist with LTE in overlapping spectrum in both normal and MBSFN LTE DL subframes. Hence, it can be possible to schedule NR PDSCH transmissions in subframes with CRS. After a dedicated RRC connection has been established, the LTE CRS pattern, including the MBSFN subframe configuration, can be known to the UE and the UE can rate match the NR PDSCH around the LTE CRS. Before the UE is configured with a dedicated RRC configuration, NR PDSCH transmissions can be confined to symbols between subsequent CRS transmissions. In MBSFN subframes, these are OFDM symbols 1-13 for one or two LTE CRS ports and OFDM symbols 2-13 otherwise. Moreover, some OFDM symbols without CRS can be reserved for NR PDCCH transmissions which cannot be rate matched around LTE CRS. NR DMRS is not expected to collide with LTE CRS. This places restrictions on possible NR PDSCH time-domain resource allocations when NR and LTE are deployed in overlapping spectrum.
Referring now to FIG. 4, illustrated is an example schematic system block diagram of physical downlink shared channel mapping type B 400 according to one or more embodiments.
FIG. 4 depicts PDCCH monitoring on any span of up to 3 consecutive OFDM symbols of a slot. For a given UE 102, search space configurations are within the same span of 3 consecutive OFDM symbols in the slot. The benefit of using PDCCH monitoring in conjunction with NR PDSCH mapping type A in LTE MBSFN subframes is that UEs 102 support the configuration. However, NR coverage can be limited with a single OFDM symbol for NR PDCCH, especially in 5 MHz carriers. Thus, PDCCH monitoring and PDSCH mapping type B can be used, which can allow an NR CORESET span of three OFDM symbols for coverage.
As in LTE, in 5G the control (e.g., up to 3 symbols) can be in the beginning of the subframe and the data at the end. Thus, in a type A configuration (e.g., FIG. 3 where the control symbols are the first three blocks and the data symbol begins on the fourth block), the first two blocks can be occupied by LTE, whereas the third block can be occupied by 5G. However, for a type B configuration, the control symbols can be limited to three, although they do not have to be at the beginning. Thus, the first two blocks can be occupied by LTE whereas, the third through the fifth blocks can be occupied by 5G. This causes the 5G reference signal (e.g. at symbol 6), and the 5G data beginning at block 7, to be shifted to the right of the grid. Consequently, the 5G system can have three symbols for coverage that do not occupy the LTE coverage symbols. Instead of 2 symbol control (e.g., 4 as the start symbol—Table 1) as depicted by FIG. 3, FIG. 4 depicts 3 symbol control (e.g., 5 as the start symbol—Table 3), which can provide more coverage.
Referring now to FIGS. 5 and 6, illustrated are example schematic system block diagrams of physical downlink shared channel mapping type B with normal long term evolution downlink subframes and rate matching 500, 600 according to one or more embodiments. FIGS. 5 and 6 also depict a higher density with CRS throughout the subframe.
In yet another embodiment, a single PDSCH allocation can span across OFDM symbols with CRS, however, instead of rate matching around CRS at the RsE level, entire OFDM symbols can be rate matched as depicted in FIGS. 5 and 6. In this embodiment, a table can be defined, which in addition to the PDSCH mapping type (A or B) and the values for K₀, S and L also incorporate the OFDM symbol indices onto which the corresponding PDSCH is not mapped. In the example in FIG. 5, for instance, K₀=0, S=5, and L=9 and in FIG. 6 and K₀=0, S=5 and L=7, whereby in both cases OFDM symbols {7,8,11} are avoided. The benefit of this solution is reduced overhead. Because a single PDSCH allocation is used that avoids OFDM symbols carrying CRS, a single DMRS symbol and a single PDCCH control channel suffice for demodulating and scheduling the single PDSCH, respectively. Thus, type B starts at 5 and length at 7 applied to a normal downlink subframe and leaves the symbol to the CRS unoccupied. For type B, the length can be restricted to 2, 4, and 7. Therefore the NRPDSCH can be at symbol 7. For type A, the length can be any number between 1 to 14.

A computing device can typically include a variety of machine-readable media. Machine-readable media can be any available media that can be accessed by the computer and includes both volatile and non-volatile media, removable and non-removable media. By way of example and not limitation, computer-readable media can comprise computer storage media and communication media.

In order to provide additional context for various aspects thereof, FIG. 12 and the following discussion are intended to provide a brief, general description of a suitable computing environment in which the various aspects of the innovation can be implemented to facilitate the establishment of a transaction between an entity and a third party. While the description above is in the general context of computer-executable instructions that can run on one or more computers, those skilled in the art will recognize that the innovation also can be implemented in combination with other program modules and/or as a combination of hardware and software.
Generally, program modules include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the various methods can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, minicomputers, mainframe computers, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices.
The illustrated aspects of the innovation can also be practiced in distributed computing environments where certain tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.
Computing devices typically include a variety of media, which can include computer-readable storage media or communications media, which two terms are used herein differently from one another as follows.
Computer-readable storage media can be any available storage media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable instructions, program modules, structured data, or unstructured data. Computer-readable storage media can include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disk (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or other tangible and/or non-transitory media which can be used to store desired information. Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium.
Communications media can embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communication media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.
With reference to FIG. 12, implementing various aspects described herein with regards to the end-user device can include a computer 1200, the computer 1200 including a processing unit 1204, a system memory 1206 and a system bus 1208. The system bus 1208 couples system components including, but not limited to, the system memory 1206 to the processing unit 1204. The processing unit 1204 can be any of various commercially available processors. Dual microprocessors and other multi processor architectures can also be employed as the processing unit 1204.
The system bus 1208 can be any of several types of bus structure that can further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory 1206 includes read-only memory (ROM) 1227 and random access memory (RAM) 1212. A basic input/output system (BIOS) is stored in a non-volatile memory 1227 such as ROM, EPROM, EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer 1200, such as during start-up. The RAM 1212 can also include a high-speed RAM such as static RAM for caching data.
The computer 1200 further includes an internal hard disk drive (HDD) 1214 (e.g., EIDE, SATA), which internal hard disk drive 1214 can also be configured for external use in a suitable chassis (not shown), a magnetic floppy disk drive (FDD) 1216, (e.g., to read from or write to a removable diskette 1218) and an optical disk drive 1220, (e.g., reading a CD-ROM disk 1222 or, to read from or write to other high capacity optical media such as the DVD). The hard disk drive 1214, magnetic disk drive 1216 and optical disk drive 1220 can be connected to the system bus 1208 by a hard disk drive interface 1224, a magnetic disk drive interface 1226 and an optical drive interface 1228, respectively. The interface 1224 for external drive implementations includes at least one or both of Universal Serial Bus (USB) and IEEE 1294 interface technologies. Other external drive connection technologies are within contemplation of the subject innovation.
The drives and their associated computer-readable media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer 1200 the drives and media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable media above refers to a HDD, a removable magnetic diskette, and a removable optical media such as a CD or DVD, it should be appreciated by those skilled in the art that other types of media which are readable by a computer 1200, such as zip drives, magnetic cassettes, flash memory cards, cartridges, and the like, can also be used in the exemplary operating environment, and further, that any such media can contain computer-executable instructions for performing the methods of the disclosed innovation.
A number of program modules can be stored in the drives and RAM 1212, including an operating system 1230, one or more application programs 1232, other program modules 1234 and program data 1236. All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM 1212. It is to be appreciated that the innovation can be implemented with various commercially available operating systems or combinations of operating systems.
A user can enter commands and information into the computer 1200 through one or more wired/wireless input devices, e.g., a keyboard 1238 and a pointing device, such as a mouse 1240. Other input devices (not shown) may include a microphone, an IR remote control, a joystick, a game pad, a stylus pen, touch screen, or the like. These and other input devices are often connected to the processing unit 1204 through an input device interface 1242 that is coupled to the system bus 1208, but can be connected by other interfaces, such as a parallel port, an IEEE 2394 serial port, a game port, a USB port, an IR interface, etc.
A monitor 1244 or other type of display device is also connected to the system bus 1208 through an interface, such as a video adapter 1246. In addition to the monitor 1244, a computer 1200 typically includes other peripheral output devices (not shown), such as speakers, printers, etc.
The computer 1200 can operate in a networked environment using logical connections by wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 1248. The remote computer(s) 1248 can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment device, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer, although, for purposes of brevity, only a memory/storage device 1250 is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network (LAN) 1252 and/or larger networks, e.g., a wide area network (WAN) 1254. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which may connect to a global communications network, e.g., the Internet.
When used in a LAN networking environment, the computer 1200 is connected to the local network 1252 through a wired and/or wireless communication network interface or adapter 1256. The adapter 1256 may facilitate wired or wireless communication to the LAN 1252, which may also include a wireless access point disposed thereon for communicating with the wireless adapter 1256.
When used in a WAN networking environment, the computer 1200 can include a modem 1258, or is connected to a communications server on the WAN 1254, or has other means for establishing communications over the WAN 1254, such as by way of the Internet. The modem 1258, which can be internal or external and a wired or wireless device, is connected to the system bus 1208 through the input device interface 1242. In a networked environment, program modules depicted relative to the computer, or portions thereof, can be stored in the remote memory/storage device 1250. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers can be used.
The computer is operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, restroom), and telephone. This includes at least Wi-Fi and Bluetooth™ wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.
Wi-Fi, or Wireless Fidelity, allows connection to the Internet from a couch at home, a bed in a hotel room, or a conference room at work, without wires. Wi-Fi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE 802.11 (a, b, g, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps (802.11a) or 54 Mbps (802.11b) data rate, for example, or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic 10BaseT wired Ethernet networks used in many offices.
