Description

RESOURCE ALLOCATION INDICATION FOR PHYSICAL UPLINK CONTROL

CHANNEL (PUCCH)

REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application Numbers 62/373,193 filed August 10, 2016, entitled "RESOURCE ALLOCATION INDICATION FOR PUCCH IN MULTEFIRE SYSTEMS", the contents of which are herein

incorporated by reference in their entirety.

FIELD

[0002] The present disclosure relates to wireless technology, and more specifically to techniques for signaling transmissions indicating a resource allocation for physical uplink control channel (PUCCH).

BACKGROUND

[0003] The explosive wireless traffic growth leads to an urgent need of rate improvement. With mature physical layer techniques, further improvement in the spectral efficiency will be marginal. On the other hand, the scarcity of licensed spectrum in low frequency band results in a deficit in the data rate boost. Thus, there are emerging interests in the operation of LTE systems in unlicensed spectrum. As a result, one major enhancement for LTE in 3GPP Release 13 has been to enable its operation in the unlicensed spectrum via (enhanced) Licensed-Assisted Access ((e)LAA), which expands the system bandwidth by utilizing the flexible carrier aggregation (CA) framework introduced by the LTE-Advanced system. Enhanced operation of LTE systems in unlicensed spectrum is expected in future releases and 5G systems.

Potential LTE operation in unlicensed spectrum includes but not limited to the LTE operation in the unlicensed spectrum via dual connectivity (DC) - called DC based licensed assisted access (LAA) herein, and the standalone LTE system in the unlicensed spectrum, where LTE-based technology solely operates in unlicensed spectrum without requiring an "anchor" in licensed spectrum - called MulteFire.

MulteFire, combining the performance benefits of LTE technology with the simplicity of Wi-Fi-like deployments, is envisioned as a significantly important technology component to meet the ever-increasing wireless traffic. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0011] The present disclosure will now be described with reference to the attached drawing figures, wherein like reference numerals are used to refer to like elements throughout, and wherein the illustrated structures and devices are not necessarily drawn to scale. As utilized herein, terms "component," "system," "interface," and the like are intended to refer to a computer-related entity, hardware, software (e.g., in execution), and/or firmware. For example, a component can be a processor (e.g., a microprocessor, a controller, or other processing device), a process running on a processor, a controller, an object, an executable, a program, a storage device, a computer, a tablet PC and/or a user equipment (UE) (e.g., mobile / wireless phone, etc.) with a processing device. By way of illustration, an application running on a server and the server can also be a component. One or more components can reside within a process, and a component can be localized on one computer and/or distributed between two or more computers. A set of elements or a set of other components can be described herein, in which the term "set" can be interpreted as "one or more." [0012] Further, these components can execute from various computer readable storage media having various data structures stored thereon such as with a module, for example. The components can communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network, such as, the Internet, a local area network, a wide area network, or similar network with other systems via the signal).

[0013] As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, in which the electric or electronic circuitry can be operated by a software application or a firmware application executed by one or more processors. The one or more processors can be internal or external to the apparatus and can execute at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts; the electronic components can include one or more processors therein to execute software and/or firmware that confer(s), at least in part, the functionality of the electronic components.

[0014] Use of the word exemplary is intended to present concepts in a concrete fashion. As used in this application, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or". That is, unless specified otherwise, or clear from context, "X employs A or B" is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then "X employs A or B" is satisfied under any of the foregoing instances. In addition, the articles "a" and "an" as used in this application and the appended claims should generally be construed to mean "one or more" unless specified otherwise or clear from context to be directed to a singular form. Furthermore, to the extent that the terms "including", "includes", "having", "has", "with", or variants thereof are used in either the detailed description and the claims, such terms are intended to be inclusive in a manner similar to the term

"comprising."

OVERVIEW

[0015] In consideration of the above described deficiencies, various aspects / embodiments in component or techniques are disclosed for MulteFire systems. Different from the CA based (e)LAA systems, which can have ideal backhaul between a primary cell (PCell) and secondary cells (SCells), and the system information can be transmitted over licensed spectrum, there is no "anchor" in licensed spectrum in MulteFire. Thus, for the standalone systems, including but not limited to MulteFire, system information including the Master Information Block (MIB) and system information blocks (SIBs) can be transmitted in unlicensed spectrum. Resource allocations from the eNB or other network device to a UE for scheduling UL transmissions on an unlicensed channel in a MulteFire network coverage can be facilitated to meet the ever increasing need of wireless traffic with ever increasing limited resources. Embodiments herein can relate to systems having SIB / MIB transmissions in unlicensed spectrum with MulteFire systems or devices, which operate in standalone or without a licensed carrier.

[0016] In particular, embodiments / aspects related to resource allocation operations for shortened physical uplink control channel (sPUCCH) and enhanced physical uplink control channel (ePUCCH), especially with respect to the sPUCCH and the ePUCCH carrying hybrid automatic repeat request - acknowledgment (HARQ-ACK) feedback in a MulteFire network. For example, one or more resource allocation for enabling sPUCCH/ePUCCH can be a semi-static signaling configured by higher layer signaling (e.g., radio resource control (RRC) signaling), in which higher layer signaling can be signaling that originates from or in a protocol layer that can be higher than a physical PHY layer, for example. A semi-static signaling can refer to semi-persistent signaling, which can configure a parameter or property for a fixed duration or period of time, for example.

[0017] In other aspects, indicating resource allocations for sPUCCH/ePUCCH can include dynamic configuration, in which the resources being allocated can be changed or modified on a continuing basis depending on network conditions or parameters. In particular, the resource allocations can be signaled via / by / through an

acknowledgement resource indicator (ARI) in a downlink control information (DCI), or based on a CCE index (e.g., a first CCE index) of the DCI. For example, the ARI can reuse transmit power control (TPC) command bits, or downlink assignment index (DAI) bits to signal resource allocations. Alternatively or additionally, additional bits can be introduced for ARI, in which to signal for sPUCCH/ePUCCH. A mapping from CCE index to the sPUCCH/ePUCCH resource can be defined. One or more combinations of elements of these embodiments can also be implemented. Additional aspects and details of the disclosure are further described below with reference to figures.

[0018] FIG. 1 illustrates an example non-limiting wireless communications environment 100 that can enable a downlink (DL) transmission with resource allocation indications for sPUCCH/ePUCCH to carry HARQ-ACK feedback in a MulteFire network. The resource indication can include data / indications / bits / power / bandwidth / or other network parameters / properties / resources for uplink (UL) transmissions by a user equipment (UE) or other network device in a MulteFire network. Some of the resources can comprise one or more of: time domain resource (e.g. which subframe), an interlace assignment, an orthogonal covering code (OCC), or a demodulation reference symbol (DMRS) sequence and cyclic shift (CS), to enable a HARQ-ACK feedback of an uplink control information (UCI) in the UL transmission. UCI can include HARQ-ACK feedback for physical downlink shared channel (PDSCH) or other physical channel, a scheduling request (SR), or channel state information (CSI) feedback, for example.

[0019] Wireless communications environment 100 can include one or more cellular broadcast servers or macro cell network devices 1 02, 104 (e.g., primary cell device, base stations, eNBs, access points (APs) or other similar network device) as well as one or more other network devices such as small cell network devices or APs (e.g., secondary cell device, small eNBs, micro-eNBs, pico-eNBs, femto-eNBs, home eNBs (HeNBs), Wi-Fi nodes, or other similar network device) 106, 108 deployed within the wireless communications environment 100 and servicing one or more UE devices 1 10, 1 1 2, 1 14, 1 16, 1 18 for wireless communications. Each wireless communications network (e.g., cellular broadcast servers 102, 104 and small cell network devices 1 06, 108) can comprise one or more network devices (e.g., a set of network devices (NDs)) that operate in conjunction in order to process network traffic for the one or more wireless / mobile devices or UE devices 1 10, 1 1 2, 1 14, 1 1 6, or 1 18. For example, macro cell NDs 102, 104 can comprise a set of network devices that are cellular enabled network devices. In another example, the small cell network devices 106, 108 can include a set of network devices that operate with a smaller coverage zone than the macro cell network devices 102 and 104, for example, or control similar coverage zones as the macro cell devices. As one of ordinary skill in the art can appreciate, this disclosure is not limited to any one network environment architecture / deployment.

[0020] Although NDs 106 and 108 are described as small cell network devices, they can also be Wi-Fi enabled devices or wireless local area network (WLAN) devices, as well as macro cell network devices, small cell network devices, or some other type of ND operable as a base station, eNB, or a primary cell network device, for example. Alternatively, one or more of the macro cell NDs 102 and 1 04 could be small cell network devices or other NDs of a different radio access technology (RAT) that operate with different frequency carriers, for example, as small eNBs, micro-eNBs, pico-eNBs, femto-eNBs, home eNBs (HeNBs), Wi-Fi nodes, or secondary cell device also.

[0021] As illustrated, each of the one or more Wi-Fi access points 106, 1 08, for example, can have a corresponding service area 1 20, 122. Additionally, each of the one or more cellular broadcast servers or macro cell NDs 102, 104 can have a

corresponding service area 124, 126. However, it should be understood that the wireless communications environment 100 is not limited to this implementation. For example, any number of APs or NDs with respective service areas can be deployed within the wireless communications environment 100. Further, any number of cellular broadcast servers and respective service areas can be deployed within the wireless communications environment 100 as well.

[0022] Although only five UE devices 1 10, 1 12, 1 14, 1 1 6, 1 18 are illustrated, any number of UE devices can be deployed within the wireless communications

environment 100 as well. A UE device can contain some or all of the functionality of a system, subscriber unit, subscriber station, mobile station, mobile, wireless terminal, network device, mobile device, remote station, remote terminal, access terminal, user terminal, terminal, wireless communication device, wireless communication apparatus, user agent, user device, or other ND, for example.

[0023] In an example scenario, UE devices 1 10, 1 12, 1 14, 1 16, 1 18 can be serviced by networks through one of the macro cell NDs 102, 104, or small cell NDs 106, 108. As a UE device moves within the wireless communications environment 100, the respective user equipment device could move in and out of the coverage area of the associated serving network. For example, as a user is sending / receiving

communications through their respective UE device, the user might be walking, riding in a car, riding on a train, moving around a densely populated urban area (e.g., a large city), wherein the movement could cause the mobile device to be moved between various wireless communication networks. In such cases, it can be beneficial for the UE to route the network traffic (e.g., handoff) from a serving ND to a target ND in order to continue the communication (e.g., avoid dropped calls) or facilitate offloading for load distribution or other efficiency purposes, such as via LAA to unlicensed bands.

[0024] Cellular broadcast servers or macro cell NDs 102, 104 and small cell NDs 106, 108 can operate to monitor their surrounding radio conditions (e.g., by employing respective measurement components). For example, each of the macro cell NDs 102, 104 and small cell NDs 106, 108 can determine network traffic load on its respective network by performing a network diagnostic process. Various parameters associated with macro cell NDs 102, 104, small cell NDs 106, 1 08, or UE devices 1 10, 1 12, 1 14, 1 1 6, 1 18 can be detected during the network diagnostic or measurements, such as, but not limited to, frequency bands, scrambling codes, common channel pilot power, bandwidth across respective networks, universal mobile telecommunications system terrestrial radio access receive signal strength indicator, as well as frequency carrier priorities for particular cell groups (e.g., a normal group or a reduced group) and so on.

[0025] Resource allocations from the eNB 102 /106 to a UE 1 10 / 1 12, or through a WiFi node or other network device from the eNB 102 /106 to the UE 1 10 / 1 12 for scheduling UL transmissions on an unlicensed channel in a MulteFire network coverage can be facilitated to meet the ever increasing need of wireless traffic with limited resources. In an aspect, resources or a set of resource candidates to be used for sPUCCH / ePUCCH can be semi-statically configured by higher layer signaling or signaling at the RRC layer or higher layer, for example. Any layer above the PHY layer can be envisioned as a higher layer signaling as well. Resources can include time domain resources (e.g. subframe to be used for PUCCH transmission), an interlace, an OCC, a demodulation reference symbol (DMRS) sequence and DMRS cyclic shift (DMRS CS), a number of each of these, a power, frequency band, or other network signaling parameter or resource for the UL transmission, for example, which can be indicated herein according to ARI, TPC, or a CCE index. The higher layer signaling can be in conjunction with dynamic signaling or other techniques from the eNB 102 /106 to the UE 1 10 / 1 12, for example, in a combination, independently or alone.

[0026] Alternatively or additionally, signaling or indication of resources for sPUCCH / ePUCCH can be dynamic and configured by a signaling via ARI in DCI or based on a CCE index of the DCI (e.g., a first CCE index). The ARI can reuse TPC bits, or DAI bits. Additional bits for the ARI could be added alternatively, which could indicate particular resources, which may be selected from the set of resource candidates configured by higher layers, to be used specifically for the HARQ-ACK feedback in a UL transmission. In another example, a resource for sPUCCH / ePUCCH can be calculated based on a first CCE index used for PDCCH which can schedule the corresponding PDSCH. A mapping from the CCE index to the sPUCCH / ePUCCH resource can be generated or defined by the eNB 102 / 106 and communicated to the UE 1 10 / 1 12. Any combination of the above can also be envisioned. [0027] In another aspect, the sPUCCH / ePUCCH can be triggered by the eNB 1 02 / 106. The triggering can be an event or communication that triggers the UE 1 10 / 1 12 to generate sPUCCH / ePUCCH based on a set of sPUCCH / ePUCCH resources (or the resources, as described herein). The triggering mechanism can vary or be consistent. For example, a common PDCCH (cPDCCH) can trigger sPUCCH / ePUCCH, while ePUCCH can be triggered by cPDCCH or scheduled by a UL grant in a DL

transmission. The sPUCCH, for example, can be consistently triggered when special subframe or Downlink Pilot Time Slot (DwPTS) is less than 10 symbols, e.g. less than or equal to 9 minus Timing Advance (TA) set to the UEs. The DwPTS can be the portion of the DL transmission within a special subframe, or an ending subframe to a DL transmission. The sPUCCH in total duration can take up to four or less symbols, where the DL transmissions can be14 symbols and the sPUCCH occupies up to four of those symbols. So if a last DL portion (e.g., DwPTS) is smaller than 10 symbols, e.g. less than or equal to 9 minus Timing Advance (TA) set to the UEs, then there is space to switch from DL to UL and to transmit the sPUCCH. As such, the DL portion being less than 10 symbols (e.g. less than or equal to 9 minus Timing Advance (TA) set to the UEs) can trigger the sPUCCH.

[0028] As used herein, TPC bits can be utilized in a process by which the transmitter can change its output power and then retune itself by the feedback from the DL transmission. This whole process can form a cyclic loop and as a kind of control loop that can be referred to or called "Closed Loop" in control system theory, where "Open loop" can refer to one side of the communication between receiver and transmitter configuring an operation or measurement without reliance on feedback or without communication from the other side of the communication cycle. In one or more embodiments being disclosed herein, the TPC bits can be re-interpreted or re-used as ARI for PUCCH, which is further described in additional details herein.

[0029] Additionally, the CCE index can correspond to the allocation of resources from the eNB 102 / 106 to the UE 1 1 0 /1 12. For example, the number of CCEs present to transmit control information can be variable depending on the bandwidth, the physical control format indicator channel (PCFICH), or number of antenna ports that effect the reference signals present, for example. The eNB 102 / 106 generates fixed indexes for a particular UE based on the radio network temporary identifier (RNTI) or the subframe so that a UE only has to find its control information at those particular indexes. The UE can then search in a subframe for a particular search space, such as a common search space or a UE specific search space, for example. In one or more embodiments being disclosed herein, a mapping from the CCE index to HARQ-ACK resources can be defined, which is also further described in additional details herein.

[0030] The interlace can be used to support a UL transmission due to regulation on an occupied channel bandwidth, which requires the interlace to be larger than 80% of the system bandwidth, for example., which can enable a transmission for MulteFire or 5G communications, for example. This feedback can carry HARQ-ACK Information as part of a number of coded symbols used by the UE 1 10 / 1 12 to transmit the HARQ acknowledgement bits, which can be determined using the number of HARQ bits (e.g., 1 or 2 depending on the number of codewords present, and number of HARQ

processes to be transmitted), the scheduled PUSCH bandwidth expressed as a number of subcarriers or number of interlaces, the number of SC-FDMA symbols per subframe for the initial PUSCH transmission, for example. Each positive acknowledgement (ACK) can be encoded as a binary 1 and negative acknowledgement (NACK) encoded as a binary 0, or other configuration. If the HARQ-ACK consists of 1 -bit of information, corresponding to one codeword, for example, then it is first encoded according to a table (e.g., a look-up table, or the like).

[0031] Referring to FIG. 2, illustrated is an example network configured to enable the operation of legacy network devices, NextGen network devices (network devices based on a 5G network), new radio (NR) network devices, or for standalone systems (e.g., MulteFire systems), for example, which can be independent or communicatively coupled in one or more networks. These network devices can be configured to communicate via a communication protocol stack, which can be based on an Open Source Interconnected (OSI) model and defines the networking framework for implementing communication protocols among the various layers. Control can be passed from one layer to the next, starting at an application layer in one station or node, for example, proceeding to a bottom layer, over a channel to a next station and back up the hierarchy. In particular, various embodiments and aspects herein are directed to communication resource allocations for UL transmissions with UL control information (UCI) for HARQ-ACK feedback.

[0032] The network system 200 is an example of an interworking architecture for potential interworking between a legacy network (e.g. , the evolved packet core (EPC) 204 in the LTE on the left hand side) and the NextGen core 206 with the 5G radio (e.g., the RAN 21 0 based on 5G RAT on the right hand side). Each component, individually or together can be a component of an eN B, separate eNBs or WiFi nodes as either of the RANs 208 and 21 0 operatively coupled to or comprising both the EPC 204 and the NextGen core 206. Thus, the UE signaling treatment or operation can be based on whether the UE is 5G capable or not to determine if the communication flow would be steered either to the EPC core 204 or the NextGen core 206. For example, UE 21 2 can be a legacy U E with bearer based operation handling, while a UEs 21 4 or 21 6 can be 5G UEs operable for a bearer based or a flow based operation, in which QoS or other communication parameters are based on a certain communication protocol flow, for example. Other configurations for communication with multiple different technologies or RATS can be envisioned.

[0033] On the left side, a legacy UE 21 2 and the 5G U E 214 can connect to the LTE eNB with RAN based on LTE 208, and the legacy U E 21 2 has traffic handled over the S1 interface to the EPC 204, in one example, while the 5G U E 214 can have communications directed to the NextGen core 206 over the NG2 / NG3 interface(s), which can support infrastructure that can include licensed assisted accessed (LAA), enhanced LAA (eLAA), New radio, internet of things / machine to machine, MulteFire or the like. Thus, the communication handling can be different for different UEs so that one type of communication handling can be enabled for the 5G UE 214.

[0034] The components of the RAN based on LTE 208 can be employed in or as an eNB of a RAN based LTE or evolved LTE 208 configured to generate and manage cell coverage area / zone 220, while another eNB of a RAN based on 5G RAT / new RAT (NRAT) or MulteFire 210 can control the 5G based cell area 222. Although depicted as multiple coverage areas, this is only one example architecture and is not confined to any one or more cell coverage areas as illustrated on the right and left of the system 200.

[0035] In one embodied aspect, the MulteFire system operates only on the unlicensed spectrum without an anchor in the licensed spectrum, and thus, relies on the unlicensed spectrum for communication signaling, for example. This signaling includes resource allocations of the set of sPUCCH / ePUCCH resources for such UL transmission from the UE for the HARQ-ACK of the UCI. In the LAA system, the uplink control information can be usually transmitted in the licensed spectrum. For example, if the channel on unlicensed spectrum is busy and there is some delay requirement for the UL control information, in the LAA system the UL control information (UCI) can still be transmitted in the licensed spectrum. As such, there is no expectation of a large impact on the delay for the UCI with complexity of the systems, but in the MulteFire system the exact time or which time the PUCCH UCI can be transmitted is not guaranteed as much since the UCI needs to be transmitted in unlicensed spectrum. Thus, in MulteFire two PUCCH channels can be operational, which is different from LTE, namely the sPUCCH and the ePUCCH.

[0036] Referring now to FIG. 3 illustrates an example DL / UL communication signaling 300 with two different PUCCH channels, in which one is the short or sPUCCH 320 and the other the ePUCCH 330. The sPUCCH 320 can be located in a special subframe 340, which can include a first part 316 (e.g., a downlink pilot time slot

(DwPTS)) that is used to transmit the DL subframe, particularly the ending DL subframe, a switching gap 318, and a remaining part used to transmit the sPUCCH 320. The sPUCCH 320 could occupy up to four symbols. For example, the sPUCCH 320 can occupy one, two, three or four symbols.

[0037] The DL transmission, comprising PDCCH 304-308, and DL subframes 310- 31 6), can be transmitted by the eNB 102 / 106, which, before transmitting the DL, can first perform a listen before talk (LBT), such as a full or complete Cat 4 LBT protocol. If the channel (e.g., the channel for PDCCH transmission) is sensed to be idle, then the eNB 102 / 1 06 can transmit the DL transmission. If the UL transmission, which can include sPUCCH 320, PUSCH 322, or the ePUCCH 330, starts within 16 microseconds, after the gap, for example, for switching transmission and the start of the following UL transmission is within 16 microseconds, then the UE 1 10 / 1 12 does not need to perform any LBT protocol, and transmit the UL transmission, especially with HARQ- ACK UCI. This signaling is beneficial to reduce collision probability with other channels, for example. If not within the 1 6 microseconds or other predetermined duration, the UE 1 1 0 / 1 12 can operate an LBT or switching protocol (from DL reception to UL

transmission) within the gap 318 or 324, for example. The LBT protocol here can be a shorter LBT than a CAT 4 LBT with random backoff. The shorter LBT can be a single clear channel assessment (CCA) without back-off, for example, as compared to the CAT 4 LBT.

[0038] In an aspect, the DL subframes 31 0-314 are illustrated with PDCCH 304- 308, including the DCI information bits, which can trigger a UE to generate the sPUCCH 320, the ePUCCH 330 or both 320 and 330, for example, depending on the trigger. The eNB 1 02 ΙΛ 06 can thus generate a DL transmission with various triggers for the generation of sPUCCH, the ePUCCH or both.

[0039] The enhanced PUCCH or ePUCCH 330, as longer than the sPUCCH , can be transmitted over regular UL subframes, which can occupy 1 2, 1 3 or 1 4 symbols. The ePUCCH can be triggered either by a common PDCCH (cPDCCH) or a regular uplink grant. The UL grant and the cPDCCH are both transmitted over the PDCCH (e.g., any of PDCCH 304-308), in which there are some delays between that triggering (e.g., 308) and the ePUCCH channel 330. The arrow basically shows this trigger event.

[0040] In another aspect, the signaling can include an sPUCCH 320 or a long ePUCCH 330 generate in a same UL transmission burst and being controlled by the same DL transmission. Alternatively, one or the other sPUCCH 320 or long ePUCCH 330 could be controlled and triggered. The sPUCCH can be triggers consistently by the duration of the DwPTS 31 8, which means the portion of the DL transmission within this special subframe 340. For example, as long as the DwPTS 31 8 is smaller than about 1 0 symbols, (e.g., nine symbols), an sPUCCH 320 would be triggered because the total duration of the four subframes can utilize up to 14 symbols and the sPUCCH occupies up to four symbols. So if the DL portion is smaller than 1 0, then ample space is available to transmit the sPUCCH 320. This symbol amount or duration for DL subframes (including PDCCH and DCI / UL grants) being less than a predetermined threshold (e.g., ten or less) thus triggers generation of the sPUCCH 320 at the UE. For example, the eNB 1 02 / 1 06 can operate to schedule multiple UL subframes and within the UL subframes one of them can be used to transmit the ePUCCH 330 at one location, but if the window for the DL transmission subframes and control is smaller than 10 symbols then a sPUCCH 320 can be triggered, albeit at a different location than the ePUCCH 330.

[0041] FIG. 4 is an example of subcarrier mapping scheme in an interlace 400. For the MulteFire systems / devices / components, for example, can utilize a so-called Block Interleaved Frequency Division Multiple Access (B-IFMDA). For the 20 MHz bands or other spectrum bands, for example, the interlace 400 can include a first interlace 330 that corresponds to an UL transmission, including the ePUCCH, and includes physical resource blocks (PRB) of zero, ten, twenty, forty, fifty, sixty, seventy, eighty, and 90 for a total of ten resource blocks. The gap between each PRB / RB can be 1 0 PRBs.

[0042] In the example of an LTE system with 20 MHz bandwidth (BW), the total number of REs can be 1 ,200. In an interlaced resource block (RB) assignment, or a physical resource block (PRB) assignment, an interlace can be the basic resource allocation unit that can be allocated to the generation of UL transmission (e.g., for UE 1 1 0 / 1 12). One interlace, for example, can include about 10 RBs, and the number of REs in one interlace can be about 120, for example.

[0043] Unlicensed spectrums as with MulteFire, for example, operate so that each transmission occupies 80% of the total system bandwidth. This goal can be achieved with a multi-based structure such as the interlace 400, and can include about 10 PRBs, which can all be allocated to one UE (e.g., 1 1 0 / 1 12), for example, to enable

transmission generation. The gap between the first PRB at top 402 and the last PRB 420 can be larger than 80% of the total system bandwidth, which enables such an interlace structure 400 to be utilized in conjunction with this goal. The spaces (e.g., space 430) that are in-between neighboring PRBs within an interlace (e.g., 402 and 404) can represent 10 PRBs, for example. In particular, there can be 12 subcarriers per PRB, and there is a mapping of the different information blocks between slot zero and slot one, as delineated in the blow-up 450 of interlace 402. As such, the structure of one PRB 402 can include 1 2 to 14 symbols, in the time domain, depending on the resource allocation indication from the eNB 102 / 106 as to whether the first symbol is punctured or the last symbol is punctured for a CCA or LBT protocol or Sounding Reference Signal (SRS) transmission. If the eNB 102 / 106 indicates no puncturing, then in total there can be 14 symbols, but if either one or both symbols at the edges of the transmission are punctured, then the subframe duration can be about 12 to 14 symbols, for example. In the frequency domain there can be 12 subcarriers per PRB. As such, the interlace structure 400 provides an example of the physical uplink shared channel (PUSCH), as an example for the PUCCH as well.

[0044] Additionally, a UL transmission can include other data / symbols such as the demodulation reference symbols (DMRS) 440, which can represent the reference symbols that are located in the middle of the interlace 402 to the UE 1 1 0 / 1 12. The DMRS reference symbols (or pilot symbols) can be inserted in the OFDM time- frequency grid to allow for channel estimation. Each DMRS can comprises a pseudorandom signal generated in the frequency domain to be utilized for channel estimation. A sequence Index (e.g., base sequence index), cyclic shift (CS), or the OCC can be used to determine the transmitted signal corresponding to each DMRS. Cyclic shifts (CS) or DMRS CS can comprise linear phase shifts applied in the frequency domain. The OCC comprise orthogonal time domain codes / timing domain orthogonal codes, operating on the DMRS provided for each UL subframe. Orthogonal DMRS between UEs can be achieved by using CS (or DMRS sequences and CS (DMRS CS)), or OCC, for example.

[0045] The ePUCCH can also include two DMRS per slot (e.g., slot 0, slot 1 ), instead of just one as illustrated, so that in total the ePUCCH can have four DMRS 440 for an interlace 402. The DMRS locations in the PUSCH can be similar or the same as the blow-up 450 of interlace 402 in FIG. 4; However, the DMRS locations between the PUSCH and the ePUCCH can be different. For example, ePUCCH can include the DMRS in symbols 1 and 5 in each slot (e.g., slot 0, slot 1 , etc.). An interlace, for example, can have DMRS at symbols 1 , 5, 8, or 12 as illustrated, assuming the symbols for an interlace (e.g., 402) initiate from symbol zero. The DMRS can be a predefined sequence, which can enable the UE to know which sequence to utilize depending on its identification ID, time-to-transmit, transmission parameters or other communication parameters / properties as described herein. Given this known info, the UE 1 10 / 1 12 can know which sequence to use to transmit the UL transmission as a fixed set of symbols. On the eNB 102 / 106 side, the eNB 102 / 106 can also know which sequence the UE 1 10 / 1 12 would use to transmit during this DMRS. Based on this given DMRS sequence and CS, for example, the eNB 102 / 106 can perform channel estimation.

[0046] Embodiments described herein can be implemented into a system using any suitably configured hardware and/or software. FIG. 5 illustrates, for at least

[0049] In some embodiments, the baseband circuitry 504 can include elements of a protocol stack such as, for example, elements of an evolved universal terrestrial radio access network (EUTRAN) protocol including, for example, physical (PHY), media access control (MAC), radio link control (RLC), packet data convergence protocol (PDCP), and/or radio resource control (RRC) elements. A central processing unit (CPU) 504e of the baseband circuitry 504 can be configured to run elements of the protocol stack for signaling of the PHY, MAC, RLC, PDCP and/or RRC layers.

For example, in some embodiments, the baseband circuitry 504 can support communication with an evolved universal terrestrial radio access network (EUTRAN) and/or other wireless metropolitan area networks (WMAN), a wireless local area network (WLAN), a wireless personal area network (WPAN). Embodiments in which the baseband circuitry 504 is configured to support radio communications of more than one wireless protocol can be referred to as multi-mode baseband circuitry.

[0051] RF circuitry 506 can enable communication with wireless networks

RF circuitry 506 can also include a transmit signal path which can include circuitry to up- convert baseband signals provided by the baseband circuitry 504 and provide RF output signals to the FEM circuitry 508 for transmission.

[0052] In some embodiments, the RF circuitry 506 can include a receive signal path and a transmit signal path.

RF circuitry 506 can also include synthesizer circuitry 506d for synthesizing a frequency for use by the mixer circuitry 506a of the receive signal path and the transmit signal path. In some embodiments, the mixer circuitry 506a of the receive signal path can be configured to down-convert RF signals received from the FEM circuitry 508 based on the synthesized frequency provided by synthesizer circuitry 506d. The amplifier circuitry 506b can be configured to amplify the down-converted signals and the filter circuitry 506c can be a low-pass filter (LPF) or band-pass filter (BPF) configured to remove unwanted signals from the down-converted signals to generate output baseband signals. Output baseband signals can be provided to the baseband circuitry 504 for further processing. In some embodiments, the output baseband signals can be zero- frequency baseband signals, although this is not a requirement. In some embodiments, mixer circuitry 506a of the receive signal path can comprise passive mixers, although the scope of the embodiments is not limited in this respect.

[0053] In some embodiments, the mixer circuitry 506a of the transmit signal path can be configured to up-convert input baseband signals based on the synthesized frequency provided by the synthesizer circuitry 506d to generate RF output signals for the FEM circuitry 508. The baseband signals can be provided by the baseband circuitry 504 and can be filtered by filter circuitry 506c. The filter circuitry 506c can include a low-pass filter (LPF), although the scope of the embodiments is not limited in this respect.

[0054] In some embodiments, the mixer circuitry 506a of the receive signal path and the mixer circuitry 506a of the transmit signal path can include two or more mixers and can be arranged for quadrature downconversion and/or upconversion respectively. In some embodiments, the mixer circuitry 506a of the receive signal path and the mixer circuitry 506a of the transmit signal path can include two or more mixers and can be arranged for image rejection (e.g., Hartley image rejection). In some embodiments, the mixer circuitry 506a of the receive signal path and the mixer circuitry 506a can be arranged for direct downconversion and/or direct upconversion, respectively. In some embodiments, the mixer circuitry 506a of the receive signal path and the mixer circuitry 506a of the transmit signal path can be configured for super-heterodyne operation.

[0055] In some embodiments, the output baseband signals and the input baseband signals can be analog baseband signals, although the scope of the embodiments is not limited in this respect. In some alternate embodiments, the output baseband signals and the input baseband signals can be digital baseband signals.

[0056] In some dual-mode embodiments, a separate radio IC circuitry can be provided for processing signals for each spectrum, although the scope of the

embodiments is not limited in this respect.

[0057] In some embodiments, the synthesizer circuitry 506d can be a fractional-N synthesizer or a fractional N/N+1 synthesizer, although the scope of the embodiments is not limited in this respect as other types of frequency synthesizers can be suitable. For example, synthesizer circuitry 506d can be a delta-sigma synthesizer, a frequency multiplier, or a synthesizer comprising a phase-locked loop with a frequency divider.

[0058] The synthesizer circuitry 506d can be configured to synthesize an output frequency for use by the mixer circuitry 506a of the RF circuitry 506 based on a frequency input and a divider control input. In some embodiments, the synthesizer circuitry 506d can be a fractional N/N+1 synthesizer.

[0059] In some embodiments, frequency input can be provided by a voltage controlled oscillator (VCO), although that is not a requirement. Divider control input can be provided by either the baseband circuitry 504 or the applications processor 502 depending on the desired output frequency. In some embodiments, a divider control input (e.g., N) can be determined from a look-up table based on a channel indicated by the applications processor 502.

[0060] Synthesizer circuitry 506d of the RF circuitry 506 can include a divider, a delay-locked loop (DLL), a multiplexer and a phase accumulator. In some embodiments, the divider can be a dual modulus divider (DMD) and the phase accumulator can be a digital phase accumulator (DPA). In some embodiments, the DMD can be configured to divide the input signal by either N or N+1 (e.g., based on a carry out) to provide a fractional division ratio. In some example embodiments, the DLL can include a set of cascaded, tunable, delay elements, a phase detector, a charge pump and a D-type flip- flop. In these embodiments, the delay elements can be configured to break a VCO period up into Nd equal packets of phase, where Nd is the number of delay elements in the delay line. In this way, the DLL provides negative feedback to help ensure that the total delay through the delay line is one VCO cycle.

[0061] In some embodiments, synthesizer circuitry 506d can be configured to generate a carrier frequency as the output frequency, while in other embodiments, the output frequency can be a multiple of the carrier frequency (e.g., twice the carrier frequency, four times the carrier frequency) and used in conjunction with quadrature generator and divider circuitry to generate multiple signals at the carrier frequency with multiple different phases with respect to each other. In some embodiments, the output frequency can be a LO frequency (f|_o)- In some embodiments, the RF circuitry 506 can include an IQ/polar converter.

[0062] FEM circuitry 508 can include a receive signal path which can include circuitry configured to operate on RF signals received from one or more antennas 510, amplify the received signals and provide the amplified versions of the received signals to the RF circuitry 506 for further processing. FEM circuitry 508 can also include a transmit signal path which can include circuitry configured to amplify signals for transmission provided by the RF circuitry 506 for transmission by one or more of the one or more antennas 51 0.

[0063] In some embodiments, the FEM circuitry 508 can include a TX/RX switch to switch between transmit mode and receive mode operation. The FEM circuitry can include a receive signal path and a transmit signal path. The receive signal path of the FEM circuitry can include a low-noise amplifier (LNA) to amplify received RF signals and provide the amplified received RF signals as an output (e.g., to the RF circuitry 506). The transmit signal path of the FEM circuitry 508 can include a power amplifier (PA) to amplify input RF signals (e.g., provided by RF circuitry 506), and one or more filters to generate RF signals for subsequent transmission (e.g., by one or more of the one or more antennas 51 0.

[0064] In some embodiments, the device 500 can include additional elements such as, for example, memory/storage, display, camera, sensor, or an input/output (I/O) interface. In addition, the device 500 can include the components discussed herein to further generate or process resource allocations or resource allocation indications of resources corresponding to the set of sPUCCH / ePUCCH resources that can be used for an uplink (UL) transmission. The UL transmission can include sPUCCH / ePUCCH, which can include various UCI, such as HARQ-ACK feedback of the PDSCH, scheduling requests (SR), or CSI feedback, for example.

[0065] Various resource allocation indication processes or operations can be particular for sPUCCH, ePUCCH, or both. For example, the eNB 102 / 106 by one or more components of the device 500 can operate to configure a set of sPUCCH / ePUCCH resources for the UE 1 10 / 1 12 based on a control channel element (CCE) index of a DCI. One or more processors / components discloses can be configured to generate a mapping from a CCE index or CCE indices to the set of sPUCCH / ePUCCH resources, including, for example, an interlace, an OCC, or a demodulation reference symbol sequence / cyclic shift (DMRS CS). The mapping, for example, can be a function of a number of assigned interlaces and a total number of intra-symbol or inter- symbol OCCs. Further, another mapping can be generated also between the OCC and the DMRS CS, by which the UE can derive from the received DL transmission.

[0066] As described above, the PUCCH resource can includes multiple resources, for example, in the frequency domain. The interlace 400, for example, can be used by the UE to generate a PUCCH transmission as an UL transmission. The OCC, for example, can be applied on each of the data symbols (e.g., OFDMA symbols, or the like) to multiplex various UEs 1 10 / 1 12. The CCE index can also be indicated for the PUCCH as a part of resource allocation, along with the DMRS to determine different versions as with a cyclic shift (CS) to multiplex reference signals depending upon differing amounts of the CS so the reference symbols can be orthogonal to each other. Thus, if two UEs 1 10 / 1 1 2, for example, are multiplexed, two different amounts of CSs can correspond to the DMRS and also for a data symbol two sets of the OCCs can be allocated. The two UEs 1 10 / 1 1 2 can then be transmitted at the same time on the same frequency resource. The eNB 102 /106, as these resources can be indicated by the eNB 102 / 1 06, has knowledge of which OCC and which CS has been used, and then uses this knowledge to detect the information from the two different UEs 1 1 0 / 1 12, for example.

[0067] Resources for sPUCCH / ePUCCH can be semi-statically configured by higher layer signaling (e.g., RRC signaling). Alternatively or additionally, resources for sPUCCH / ePUCCH can be dynamically configured. In one aspect, this can be signaled via ARI in DCI, or based on the 1 st CCE index of the DCI. In another aspect, the ARI can reuse TPC bits, or DAI bits; Alternatively, additional bits can be introduced for ARI to handle this specific purpose of signaling sPUCCH / ePUCCH resources. The resources for sPUCCH / ePUCCH can then be calculated at the UE 1 10 / 1 12 based on a first CCE index, for example. Any one or all of these various techniques / operations / processes can be combined and utilized for signaling the sPUCCH / ePUCCH resources for HARQ-ACK feedback of an UL transmission to be generated. In other details of embodiments herein, resource allocation indications for sPUCCH and ePUCCH in MulteFire systems, for example can relate to sPUCCH / ePUCCH carrying HARQ-ACK feedback, and further described in detail below.

[0068] As described, resources for sPUCCH / ePUCCH can be semi-statically configured by higher layer signaling, such as by RRC signaling. Semi-static

configuration can also be considered semi-persistent signaling, in which configurations / parameters / properties or related resources allocated can be enabled for a fixed period of time or duration. In one embodiment, a part of the resources (e.g., sPUCCH / ePUCCH resources) can be semi-statically configured, while another part of the resources can be configured dynamically. For example, one or more of these resources can be indicated or allocated by indication semi-statically with respect to the OCC as a resource to be used, while the remaining or other resources (e.g. the interlace(s), number of interlaces, interlace format, or other related parameters / property) to be used, can be dynamically indicated.

[0069] For embodiments or aspects related to resources for sPUCCH/ePUCCH being dynamically configured, different mechanisms can be enabled / utilized by the eNB 102 / 1 06 and UE 1 10 / 1 12. In one embodiment related to such dynamic configuration, the ARI can be used to indicate the resources for sPUCCH / ePUCCH to carry HARQ-ACK feedback in a UL transmission. The ARI or the acknowledgement resource indictor can be a field in the DCI. The TPC bits in the DCI can comprise two bits, for example, to indicate the TPC for power control. Specifically in this embodiment, TPC bits can be used as the ARI for resource allocation for HARQ-ACK feedback in UL. These bits can be utilized as ARI that further indicate the resources for the sPUCCH / ePUCCH carrying the HARQ-ACK feedback. The TPC bits can be configured to convey these resources in combination with power transmit data / information as their originally intended, or in lieu of such data / information. As such, the TPC bits in DCI, which is used to schedule PDSCH, can be reused as ARI for the sPUCCH / ePUCCH resource allocation.

[0070] In an aspect of reusing TPC bits for dynamic resource allocation, only the TPC bits with a DL assignment index (DAI >1 ) greater than one could be used or assigned to the ARI. In addition, TPC bits associated with a DAI equal to one (DAI = 1 ) can be used for power control. In this manner, both ARI being communicated in the TPC can be communicated, as well as the transmit power for transmission in a physical channel.

[0071] In another aspect of reusing TPC bits for dynamic resource allocation indications, the TPC bits in all DCI for PDSCH scheduling can be used as the ARI to indicate resources for HARQ-ACK feedback carried by sPUCCH / ePUCCH. At the same time, power control indication, normally provided by / in the TPC can be based on an open loop power control at the UE 1 10 / 1 12, for example. Open loop power control can mean that the UE 1 10 / 1 12 measures the DL transmission signal it is receiving, and attempts to determine whether the channel is good or bad (above or below a noise threshold or busy) and adjusts its power correspondingly. Alternatively or additionally, the power control indication(s) can be indicated by other signaling techniques, such as via (or by) other DCI formats (e.g., DCI format 3 / 3A), or based on the TPC bits in a UL grant of the DL (e.g., DCI format 0 / 4). [0072] In another embodiment for dynamic resource allocation, the set of sPUCCH / ePUCCH resources (e.g., interlaces / number of interlaces / OCC / number of OCCs / DMRS and CS / number of DMRS and CS / CCE index(es) / etc.) can be based on or a function of HARQ-ACK bundling. For example, in response to HARQ-ACK bundling is not supported / enabled, then DAI bits can be reused for ARI.

[0073] In another embodiment for dynamic resource allocation, additional ARI bits can be introduced to PDCCH. In other words, a new field dedicated for the ARI can be introduced to PDCCH and configured by the eNB 102 / 106, for example.

[0074] In other embodiments for dynamic resource allocations, the sPUCCH / ePUCCH resources can be based on the CCE index of the PDCCH for PDSCH scheduling. The first (1 ^st) CCE index, for example, as denoted by n_CcE, can be used for sPUCCH / ePUCCH resource allocation indication.

[0075] In one aspect, a mapping from the CCE index n_CcE to the set of resources (e.g., including interlace, OCC, DMRS CS, etc.) can be defined or generated by the eNB 102 / 1 06 for the UE 1 10 / 1 12. The number of OCCs (including both intra-symbol and inter-symbol OCCs) can be denoted by N₀cc- Intra-symbol means within a same symbol of a set of subcarriers, and inter-symbol among different symbols or different sets of subcarriers, in which the OCC can be applied to mitigate signal interference from multiple UEs, for example. The number of DMRS cyclic shifts by N_Cs- Let N_int_eriace be the number of interlaces, if only 1 interlace will be assigned, or be the total number of all possible sets of interlace assignments (e.g. interlaces {2, 3} or {3, 4, 5}, or even {1 , 4, 9} if discontinuous interlace allocation is supported) when multiple interlaces can be assigned. The mapping can be represented as the mapping or mapping function f(n_CcE, Ninteriace, N₀cc) = mod(n_CcE + x, N_interiace ^* N₀cc), where x can be 0, or any integer numbers. The DMRS cyclic shifts (or DMRS CSs) can be determined based on the OCC, in which there can exist a mapping between the OCC and DMRS CS to be used. In one example, similar to legacy LTE PUCCH format 1 a / 1 b, x can be 1 +N_PUCCH, where N_PUCCH is configured by higher layers (e.g., RRC signaling or the like), which can be the same as the parameter for PUCCH format 1 a / 1 b, or can be a different parameter. The N_PUCCH parameter, for example, can be an integer with a value (e.g., 0, 1 , 2047) whose value can be configured by RRC signaling and used by a network device (e.g., eNB 102) to define resources of PUCCH format in addition to the CCE index. A different parameter can refer to a value configured for PUCCH format 1 a / 1 b that can be different than the value configured for sPUCCH / ePUCCH. [0076] Alternatively or additionally, a set of resources can be pre-configured via higher layer signaling (e.g., RRC), in which the number of the possible resources can be denoted or represented by Y for any one or more particular resources (e.g., the interlace, OCC, DMRS CS, CCE index, or the like). The mapping from the CCE index n_CcE to the one or more sPUCCH / ePUCCH resources can be represented as f(n_CcE, Interlace, N_0Cc) = mod(n_CCE + , Y). Similar to the above, x can be 1 + N _PUCCH, where NPUCCH can be configured by one or more higher layers, which can be the same as the parameter for PUCCH format 1 a / 1 b, or can be a different parameter.

[0077] In another aspect, the CCE index can be used to dynamically indicate a subset of the resources, such as either the interlace(s) to be used or the OCC. For example, the mapping or mapping function f(n_CcE, N_interiace, N₀cc) = mod(n_CcE + x, Ninteriace), while a default OCC can be used in this case. The OCC can further be semi- statically configured by higher layers, for example, via the parameter N_PUCCH similar to legacy PUCCH format 1 a / 1 b. Similar to the above, x can be 1 +N_PUCCH, where N_PUCCH can be configured by higher layers, which can be the same as the parameter for PUCCH format 1 a / 1 b, or can be a different parameter. Again, N_int_eriace can be the number of interlaces or interlace indexes, if or in response to only 1 interlace being assigned, or can be the total number of all possible sets of interlace assignments (e.g. interlaces {2, 3} or {3, 4, 5}, or even {1 , 4, 9} if discontinuous interlace allocation is supported) when multiple interlaces can be assigned. Any combination of the above aspects or embodiments are envisioned as one of ordinary skill in the art can appreciate. As such, the CCE index, for example, can configure only one or more of the resources as a part of the resources for sPUCCH / ePUCCH, while at least one of: the OCC or the CS, can be configured by higher layer signaling, for a different combination, for example, can be implemented accordingly.

[0078] In another example, the UE 1 10 / 1 12 can use a set of sPUCCH / ePUCCH resources based on whether HARQ-ACK bundling is generated or supported. As such, the UL transmission can be based on an acknowledgement resource indicator (ARI) in response to a HARQ-ACK bundling operation, or based on a CCE index of a physical downlink control channel (PDCCH) in response no HARQ-ACK bundling being supported. When no HARQ-bundling is supported, for example, a one-to-one correspondence between uplink control information (UCI) and DL subframes of the DL transmission is generated in the DL (i.e. without HARQ-ACK bundling), rather than the UCI corresponding to multiple DL subframes, for example. Thus, the UE 1 10 / 1 1 2 can then generate a HARQ-ACK feedback in the UCI based on the set of sPUCCH / ePUCCH resources. In further example, when the UE receives only one PDCCH for PDSCH assignment within a HARQ bundling window, or all the PDSCHs received within the HARQ bundling window are based on semi-persistent or semi-static scheduling (the sPUCCH / ePUCCH resources can use the pre-configured resources (e.g. signaled by RRC), or be determined based on the first CCE index of the PDCCH. On the other hand, or alternatively, when the UE 1 10 / 1 12 receives multiple DCIs for PDSCH scheduling, the TPC fields within the DCIs with or corresponding to a DAI > 1 can then be used as ARI. The sPUCCH / ePUCCH carrying the corresponding HARQ-ACK feedback can then use the resources indicated by ARI.

[0079] In one embodiment, the above techniques can apply to ePUCCH, regardless of which triggering is used for ePUCCH (e.g., cPDCCH or UL grant). When ePUCCH is scheduled by UL grant, the UE could ignore the resource allocation field in the UL grant when ePUCCH is triggered explicitly by the UL grant. Alternatively, the above techniques / embodiments / aspects of this disclosure could only apply to ePUCCH when triggered by cPDCCH.
