[Technical field]
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Patent Application No. 17 / 229,559, filed April 13, 2021, which is assigned to the assignee of the present application and is hereby expressly incorporated by reference in its entirety as if fully set forth below for all applicable purposes.
[0002] Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for implementing multi-slot transport block transmission with frequency hopping. [Background technology]
[0003] Wireless communication systems are widely deployed to provide various telecommunication services, such as telephone, video, data, messaging, broadcast, and the like. These wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, and the like). Examples of such multiple access systems include Third Generation Partnership Project (3GPP®) Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, Code Division Multiple Access (CDMA®) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, to name a few.
[0004] These multiple access technologies are being adopted in various telecommunications standards to provide a common protocol that allows different wireless devices to communicate on a city, national, regional, or even global scale. New Radio (e.g., 5GNR) is an example of an emerging telecommunications standard. NR is a set of extensions to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, utilizing new spectrum, and better integrating with other open standards that use OFDMA with cyclic prefixes (CPs) on the downlink (DL) and uplink (UL). For these purposes, NR supports beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.
[0005] However, as the demand for mobile broadband access continues to grow, further improvements in NR and LTE technologies are needed that should be applicable to other multiple access technologies, and the telecommunications standards that employ these technologies. Summary of the Invention [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] For ease of understanding, the same reference numbers have been used, where possible, to designate identical elements common to the figures. It is contemplated that elements disclosed in one embodiment may be beneficially utilized on other embodiments without specific recitation.
[0014] Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer-readable media for implementing multi-slot transport block (TB) transmission over an uplink channel with frequency hopping. The techniques described herein enable a UE and a base station (e.g., a gNB) to determine frequency resources for each of multiple transmissions. In some cases, the location of the frequency resources for any given transmission may be determined based on a particular slot (e.g., slot index) or transmission occasion (e.g., transmission occasion index) in which the transmission is sent.
[0015] The following description provides an example of multi-slot TB transmission with frequency hopping. Changes may be made in the function and arrangement of the elements described without departing from the disclosure. Various examples may omit, substitute, or add various procedures or components, as appropriate. For example, the methods described may be performed in an order different from that described, and various steps may be added, omitted, or combined. Also, features described with respect to some examples may be combined in some other examples. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects described herein. Furthermore, the disclosure is intended to cover such apparatus or methods practiced using other structures, functions, or structures and functions in addition to or other than the various aspects of the disclosure described herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim. The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any aspect described herein as "exemplary" should not necessarily be construed as preferred or advantageous over other aspects.
[0016] In general, any number of wireless networks may be deployed within a given geographic area. Each wireless network may support a particular radio access technology (RAT) and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, etc. A frequency may also be referred to as a carrier, a subcarrier, a frequency channel, a tone, a subband, etc. Each frequency may support a single RAT within a given geographic area to avoid interference between wireless networks of different RATs.
[0017] The techniques described herein may be used for a variety of wireless networks and radio technologies. Although aspects may be described herein using terminology commonly associated with 3G, 4G, and / or New Radio (e.g., 5G NR) wireless technologies, aspects of the disclosure may be applied in other generation based communication systems.
[0018] The NR access may support various wireless communication services, such as enhanced Mobile Broadband (eMBB) targeting wide bandwidth, millimeter wave (mmW), massive machine type communication (MTC) targeting non-backward compatible MTC techniques, and / or mission critical targeting ultra-reliable low latency communication (URLLC). These services may include latency and reliability requirements. These services may also have different transmission time intervals (TTIs) to meet their respective quality of service (QoS) requirements. In addition, these services may coexist in the same subframe.
[0019] NR supports beamforming, and the beam direction can be dynamically configured. MIMO transmission with precoding can also be supported. MIMO configuration in DL can support up to eight transmit antennas with up to eight streams and multi-layer DL transmission with up to two streams per UE. Multi-layer transmission with up to two streams per UE can be supported. Aggregation of multiple cells can be supported with up to eight serving cells.
[0020] FIG. 1 illustrates an example wireless communication network 100 in which aspects of the present disclosure may be implemented.
[0021] For example, the wireless communication network 100 may include a base station (BS) 110a including a transport block (TB) manager 112 that may be configured to perform the operations 800 of FIG. 8 to schedule a UE (e.g., the UE 120a) with a multi-slot TB transmission. As shown, the UE 120a may also include a TB manager 122 that may be configured to perform the operations 700 of FIG. 7 to receive scheduling and transmit TBs in multiple slots using frequency hopping in accordance with aspects of the present disclosure.
[0022] The wireless communications network 100 may be an NR system (e.g., a 5G NR network). As shown in FIG. 1, the wireless communications network 100 may be in communication with a core network 132. The core network 132 may be in communication with one or more base stations (BSs) 110a-z (each also referred to herein individually or collectively as BSs 110) and / or user equipment (UE) 120a-y (each also referred to herein individually or collectively as UEs 120) in the wireless communications network 100 over one or more interfaces.
[0023] The BSs 110 may provide communication coverage for a particular geographic area, sometimes referred to as a "cell," which may be fixed or may move according to the location of the mobile BSs 110. In some examples, the BSs 110 may be interconnected to one another and / or to one or more other BSs or network nodes (not shown) in the wireless communications network 100 through various types of backhaul interfaces (e.g., direct physical connections, wireless connections, virtual networks, etc.) using any suitable transport network. In the example shown in FIG. 1, the BSs 110a, 110b, and 110c may be macro BSs for the macro cells 102a, 102b, and 102c, respectively. The BSs 110x may be pico BSs for the pico cells 102x. The BSs 110y and 110z may be femto BSs for the femto cells 102y and 102z, respectively. The BSs may support one or more cells.
[0024] The BS 110 communicates with the UEs 120 in the wireless communications network 100. The UEs 120 (e.g., 120x, 120y, etc.) may be dispersed throughout the wireless communications network 100, and each UE 120 may be fixed or mobile. The wireless communications network 100 may also include relay stations (e.g., relay station 110r), also referred to as relays, that receive transmissions of data and / or other information from an upstream station (e.g., BS 110a or UE 120r) and send transmissions of data and / or other information to a downstream station (e.g., UE 120 or BS 110) or relay transmissions between the UEs 120 to facilitate communication between the devices.
[0025] The network controller 130 may be in communication with a set of BSs 110 and may provide coordination and control for these BSs 110 (e.g., via a backhaul). In some instances, the network controller 130 may include a centralized unit (CU) and / or a distributed unit (DU), for example, in a 5G NR system. In an aspect, the network controller 130 may be in communication with a core network 132 (e.g., a 5G core network (5GC)), which provides various network functions such as access and mobility management, session management, user plane functions, policy control functions, authentication server functions, integrated data management, application functions, network exposure functions, network repository functions, network slice selection functions, etc.
[0026] FIG. 2 illustrates example components of a BS 110a and a UE 120a (eg, the wireless communication network 100 of FIG. 1) that may be used to implement aspects of the present disclosure.
[0027] At the BS 110a, the transmit processor 220 may receive data from the data source 212 and control information from the controller / processor 240. The control information may be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid ARQ indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), etc. The data may be for a physical downlink shared channel (PDSCH), etc. A medium access control (MAC) control element (MAC-CE) is a MAC layer communication structure that may be used to control command exchanges between wireless nodes. The MAC-CE may be carried in a shared channel, such as a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), or a physical sidelink shared channel (PSSCH).
[0028] The processor 220 may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. The transmit processor 220 may also generate reference symbols for a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a PBCH demodulation reference signal (DMRS), and a channel state information reference signal (CSI-RS), etc. The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, and / or reference symbols, if applicable, and may provide output symbol streams to modulators (MODs) in the transceivers 232a-t. Each modulator in the transceivers 232a-t may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. Downlink signals from the modulators in transceivers 232a through 232t may be transmitted via antennas 234a through 234t, respectively.
[0029] At the UE 120a, the antennas 252a-252r may receive downlink signals from the BS 110a and may provide received signals to demodulators (DEMODs) within the transceivers 254a-254r, respectively. Each demodulator within the transceivers 254a-254r may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each demodulator may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all demodulators within the transceivers 254a-254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. The receive processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 120a to a data sink 260, and provide decoded control information to the controller / processor 280.
[0030] On the uplink, at the UE 120a, a transmit processor 264 may receive and process data (e.g., for the Physical Uplink Shared Channel (PUSCH)) from a data source 262 and control information (e.g., for the Physical Uplink Control Channel (PUCCH)) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for a reference signal (e.g., for a Sounding Reference Signal (SRS)). The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by a modulator in the transceivers 254a-254r (e.g., for SC-FDM, etc.), and transmitted to the BS 110a. At the BS 110a, the uplink signal from UE 120a may be received by antenna 234, processed by demodulators in transceivers 232a-232t, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120a. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a controller / processor 240.
[0031] The memories 242 and 282 may store data and program codes for the BS 110a and the UE 120a, respectively. The scheduler 244 may schedule UEs for data transmission on the downlink and / or uplink.
[0032] The antennas 252, processors 266, 258, 264, and / or controller / processor 280 of the UE 120a and / or the antennas 234, processors 220, 230, 238, and / or controller / processor 240 of the BS 110a may be used to perform various techniques and methods described herein. For example, as shown in FIG. 2, the controller / processor 240 of the BS 110a has a TB manager 241, which may represent the TB manager 112, in accordance with aspects described herein. As shown in FIG. 2, the controller / processor 280 of the UE 120a has a TB manager 281, which may represent the TB manager 122, in accordance with aspects described herein. Although shown in the controller / processor, other components of the UE 120a and the BS 110a may be used to perform the operations described herein.
[0033] 1 and 2 as communicating with a BS and / or within a network, the UE 120a may be configured to communicate / transmit directly with / to another UE 120 or directly with / to another wireless device without relaying communications through a network. In some embodiments, the BS 110a shown in FIG. 2 and described above is an example of another UE 120.
[0034] NR may utilize orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) on the uplink and downlink. NR may support half-duplex operation using time division duplex (TDD). OFDM and single carrier frequency division multiplexing (SC-FDM) partition the system bandwidth into multiple orthogonal subcarriers, which are also commonly referred to as tones, bins, etc. Each subcarrier may be modulated with data. Modulation symbols may be sent in the frequency domain with OFDM and in the time domain with SC-FDM. The spacing between adjacent subcarriers may be fixed, and the total number of subcarriers may depend on the system bandwidth. The minimum resource allocation, called a resource block (RB), may be 12 consecutive subcarriers. The system bandwidth may also be partitioned into subbands. For example, a subband may cover multiple RBs. NR may support a base subcarrier spacing (SCS) of 15 KHz, and other SCSs (e.g., 30 kHz, 60 kHz, 120 kHz, 240 kHz, etc.) may be defined relative to the base SCS.
[0035] FIG. 3 illustrates an example of a frame format 300 for NR. A transmission timeline for each of the downlink and uplink may be partitioned into units of radio frames. Each radio frame may have a predetermined duration (e.g., 10 ms) and may be partitioned into 10 subframes, each of 1 ms, with indices 0-9. Each subframe may include a variable number of slots (e.g., 1, 2, 4, 8, 16, ... slots) depending on the SCS. Each slot may include a variable number of symbol periods (e.g., 7, 12, or 14 symbols) depending on the SCS. The symbol periods within each slot may be assigned an index. The subslot structure may refer to a transmission time interval (e.g., 2, 3, or 4 symbols) that is shorter in duration than a slot. Each symbol within a slot may be configured for a link direction (e.g., downlink (DL), uplink (UL), or flexible) for data transmission, and the link direction per subframe may be dynamically switched. The link direction may be based on the slot format. Each slot may contain DL / UL data as well as DL / UL control information.
[0036] In NR, a synchronization signal block (SSB) is transmitted. In some aspects, the SSB may be transmitted in a burst, where each SSB in a burst corresponds to a different beam direction for UE-side beam management (e.g., including beam selection and / or beam refinement). The SSB includes a PSS, an SSS, and a 2-symbol PBCH. The SSB may be transmitted in a fixed slot location, such as symbols 0-3 as shown in FIG. 3. The PSS and SSS may be used by the UE for cell search and acquisition. The PSS may provide half frame timing, and the SS may provide CP length and frame timing. The PSS and SSS may provide cell identification information. The PBCH carries some basic system information, such as downlink system bandwidth, timing information within a radio frame, SS burst periodicity, and system frame number. The SSB may be organized into SS bursts to support beam sweeping. Further system information, such as Minimum Remaining System Information (RMSI), System Information Blocks (SIB), other system information (OSI), etc., may be transmitted on the Physical Downlink Shared Channel (PDSCH) in some subframes. An SSB may be transmitted up to 64 times in an SS burst, for example, using up to 64 different beam directions for mmWave. Multiple transmissions of an SSB are called SS bursts in a half radio frame. The SSBs in an SS burst may be transmitted in the same frequency region, and the SSBs in different SS bursts may be transmitted in different frequency regions.
[0037] Exemplary Multi-Slot Transport Block Transmission In some wireless communication systems (e.g., NR), a UE may support transmission of a transport block (TB) over multiple slots (TBoMS) in the time domain. In other words, a TB may provide continuity of a data bit sequence across multiple slots. As used herein, such a TB may be referred to as a multi-slot TB transmission or a multi-slot TB.
[0038] For example, Figures 4A and 4B illustrate examples of time division duplexing (TDD) schemes for downlink (DL) and uplink (UL) slots according to some aspects of the disclosure. With reference to Figure 4A, a TDD UL-DL pattern 400A may have a periodic sequence of one UL slot followed by three DL slots. For example, a multi-slot TB 402 may include four UL slots across non-consecutive UL slots in the TDD UL-DL pattern 400A, and the multi-slot TB 402 may have a total of 56 symbols. As shown in Figure 4B, a TDD UL-DL pattern 400B may have a periodic sequence of two UL slots followed by three DL slots. In some instances, a multi-slot TB 404 may include two consecutive UL slots with a total of 28 symbols. In some aspects, a multi-slot TB 406 may include four UL slots with two pairs of consecutive UL slots with a total of 56 symbols. In other words, a multi-slot TB may include consecutive and / or non-consecutive UL slots. In some cases, a multi-slot TB may span multiple slots but may be one slot or less in length. The coded payload of a TB may be transmitted based on a single redundancy version (RV). In some cases, a TB transmission may be referred to as a transmission occasion. If repetition is allowed, a transport block may be transmitted over multiple transmission occasions.
[0039] In general, the RVs in a redundancy version (RV) sequence may span consecutive slots (referred to as option A) or non-consecutive slots (referred to as option B) of a multi-slot TB. Under option B, the UE may buffer the entire interleaved coded sequence and keep track of the starting bit in each transmission occasion of the multi-slot TB. The RV sequence may provide the RV to be used for each retransmission or iteration in a sequence of retransmissions. As an example, the RV sequence may have the following values: {0,2,3,1}, {0,3,0,3}, or {0,0,0,0}, where each element in the sequence represents a particular RV. An RV sequence of {0,2,3,1} gives that the first RV in the sequence is RV0, the second RV is RV2, the third RV is RV3, and the last RV is RV1.
[0040] 5A is a slot diagram illustrating various TDD example cases of TBoMS transmission in which Option A may be utilized. In each case, the UE may determine a transport block (TB) size based on a resource allocation across multiple slots (e.g., four slots in the illustrated example). In this example, the UE may encode the payload and transmit the encoded payload based on a single RV over the PUSCH in multiple slots.
[0041] In a first example (TDD Example 1), the UE transmits TBs in slots 3, 8, 9, and 13. In a second example (TDD Example 2), the UE transmits TBs in slots 2, 3, 8, and 9. In a third example (TDD Example 3), the UE transmits TBs in consecutive slots 3, 4, 5, and 6. In a fourth example (TDD Example 4), the UE transmits TBs in slots 3, 4, 6, and 7.
[0042] 5B is a slot diagram illustrating various cases in which options A and B may be implemented in a TDD or frequency division duplex (FDD) deployment according to some aspects of the disclosure. The RV sequences applied in these examples are RV0, RV2, RV3, and RV1 from a circular buffer 512. In a TDD example 502, each RV is contained in a separate slot under option A. In a TDD example 504, each RV spans two consecutive slots under option A. In a TDD example 506, the RV spans non-consecutive slots under option B. In an FDD example 508, each RV spans consecutive slots under option A. In an FDD example 510, the RV spans non-consecutive slots under option B.
[0043] Exemplary Multi-Slot Transport Block Transmission with Frequency Hopping Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for implementing multi-slot transport block (TB) transmission over an uplink channel that employs frequency hopping.
[0044] The techniques described herein enable a UE and a base station (e.g., a gNB) to determine a frequency resource for each of multiple transmissions of a TB (e.g., across multiple slots in a PUSCH). In some cases, the location of the frequency resource for any given transmission may be determined based on the particular slot (e.g., slot index) or transmission occasion (e.g., transmission occasion index) in which the transmission is sent.
[0045] Figure 6 shows how frequency hopping may be used in the first two examples shown in Figure 5A. As shown, for TDD Example 1, a first frequency hopping resource may be used for transmissions in slots 3 and 9, and a second frequency hopping resource may be used for transmissions in slots 8 and 13. Similarly, for TDD Example 2, a first frequency hopping resource may be used for transmissions in slots 2 and 8, and a second frequency hopping resource may be used for transmissions in slots 3 and 9.
[0046] In this manner, frequency hopping within a TBoMS transmission may improve the performance of the transmission using frequency diversity. This disclosure also provides various options for how to enable frequency hopping within a TBoMS transmission and how to determine the frequency resources for each hop.
[0047] 7 is a flow diagram illustrating example operations 700 for wireless communication according to some aspects of the disclosure. The operations 700 may be performed, for example, by a UE (such as UE 120a in wireless communication network 100). The operations 700 may be implemented as software components executed and operating on one or more processors (e.g., controller / processor 280 of FIG. 2). Furthermore, the transmission and reception of signals by the UE in the operations 700 may be enabled, for example, by one or more antennas (e.g., antenna 252 of FIG. 2). In some aspects, the transmission and / or reception of signals by the UE may be performed via a bus interface of one or more processors (e.g., controller / processor 280) that acquires and / or outputs the signals.
[0048] The operations 700 begin, at 702, by receiving a scheduling for at least one transport block to be transmitted over a number of slots.
[0049] At 704, the UE transmits the transport block in multiple transmission occasions over multiple slots according to frequency hopping applied to vary frequency resources used across the transmission occasions, where each transmission may be over a physical UL channel, such as a physical uplink shared channel (PUSCH).
[0050] FIG. 8 is a flow diagram illustrating example operations 800 for wireless communication according to some aspects of the disclosure. The operations 800 may be performed, for example, by a network entity (such as BS 110a in wireless communication network 100). The operations 800 may be complementary to the operations 700 performed by a UE. The operations 800 may be implemented as software components executed and operating on one or more processors (e.g., controller / processor 240 of FIG. 2). Furthermore, the transmission and reception of signals by the network entity in the operations 800 may be enabled, for example, by one or more antennas (e.g., antenna 234 of FIG. 2). In some aspects, the transmission and / or reception of signals by the network entity may be implemented via a bus interface of one or more processors (e.g., controller / processor 240) that obtain and / or output the signals. A network entity as used herein may refer to a wireless communication device in a radio access network, such as a base station, a remote radio head or antenna panel in communication with a base station, and / or a network controller.
[0051] The operations 800 begin, at 802, by transmitting signaling to a user equipment (UE) that schedules the UE to transmit at least one transport block over a number of slots.
[0052] At 804, the network entity monitors for a transport block at multiple transmission occasions over multiple slots according to frequency hopping applied to vary frequency resources used across the transmission occasions.
[0053] In some cases, frequency hopping may be determined based on the TBoMS transmission occasion. Depending on the configuration, frequency hopping may occur across slots (inter-slot) or across transmission occasions (inter-TO). TO generally refers to resources available for TBoMS transmission. Although the examples described herein and shown in the figures show a single-slot TO, a TO may span multiple slots. Thus, frequency hopping may be applied within a TO, which is referred to herein as intra-TO frequency hopping.
[0054] When a TBoMS transmission is configured, a frequency hop for the TBoMS transmission occasion may be determined based on a TBoMS transmission occasion (TO) index or a logical scheduled slot index.
[0055] FIG. 9 shows an example of frequency hopping across slots. As shown, the frequency resources in each slot are assigned to a starting resource block (RB) in the UL BWP as calculated from the resource block assignment information of the resource allocation. start ), and offset value RB offset RB offset is the frequency offset in RBs between two frequency hops (adjacent slots in this example). The starting RB for the nth TBoMS transmission occasion or the nth logical scheduled slot is given by:
[0056]
number
[0057] so that the starting RB for even slot n (assuming n is even) is RB start and the starting RB for odd slot n+1 is RB start +RB offset It is.
[0058] Figure 10A shows an example of how frequency hopping according to the above formulas may be performed for TDD Example 1 shown in Figure 5A. As shown, odd-numbered transmission occasions (first and third TOs in slots 3 and 9) or logical slot indices use frequency hop 1, and even-numbered transmission occasions (second and fourth TOs in slots 8 and 13) or logical slot indices use frequency hop 2.
[0059] Figure 10B shows an example of how frequency hopping according to the above formula may be performed for the FDD embodiment shown in Figure 5 A. As shown, odd transmission occasions (first and third TOs in slots 3 and 6) use frequency hop 1, and even transmission occasions (second and fourth TOs in slots 4 and 7) use frequency hop 2.
[0060] As demonstrated by the examples shown in Figures 10A and 10B, the definition for slot index may refer to a physical slot index or a logical slot index. In TDD Example 1 of Figure 10A, for example, the physical slot index for transmission in the second TO is 8 and the logical slot index is 1 (with indexing starting from 0 as shown).
[0061] As shown in FIG. 11, in some cases, frequency hopping can occur within a slot (intra-slot) or within a transmission occasion (intra-TO). Similar to the inter-slot (or inter-TO) example described above, the frequency resources per intra-slot (or intra-TO) hop are determined by the starting resource block (RB start ) and offset value RBoffset In this way, the frequency resource may be changed within a TB transmission.
[0062] In some cases, when a UE is configured for TBoMS transmission, intra-slot or intra-TO frequency hopping may be configured for TBoMS transmission. For some cases, when a UE is configured for TBoMS transmission, only intra-TO or inter-TO frequency hopping may be configured for TBoMS transmission.

[0087] The techniques described herein may be used for various wireless communication technologies, such as NR (e.g., 5G NR), 3GPP Long Term Evolution (LTE), LTE Advanced (LTE-A), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network may implement a radio technology, such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA), and other variants of CDMA. cdma2000 covers IS-2000, IS-95, and IS-856 standards. A TDMA network may implement a radio technology such as Global System for Mobile Communications (GSM). An OFDMA network may implement a radio technology such as NR (e.g., 5G RA), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash OFDMA, etc. UTRA and E-UTRA are parts of the Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). cdma2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). NR is an emerging wireless communications technology under development.
[0088] In 3GPP, the term "cell" can refer to a coverage area of a Node B (NB) and / or an NB subsystem serving this coverage area, depending on the context in which the term is used. In an NR system, the terms "cell" and BS, next generation Node B (gNB or gNode B), access point (AP), distributed unit (DU), carrier, or transmit reception point (TRP) may be used interchangeably. A BS may provide communication coverage for a macrocell, a picocell, a femtocell, and / or other types of cells. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs with service subscriptions. A picocell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having an association with the femtocell (e.g., UEs in a Closed Subscriber Group (CSG), UEs for users in the home, etc.). A BS for a macrocell may be referred to as a macro BS. A BS for a picocell may be referred to as a pico BS. A BS for a femtocell may be referred to as a femto BS or a home BS.
[0089] A UE may also be referred to as a mobile station, terminal, access terminal, subscriber unit, station, customer premises equipment (CPE), cellular phone, smartphone, personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet computer, camera, gaming device, netbook, smartbook, ultrabook, appliance, medical device or equipment, biometric sensor / device, wearable device such as smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.), entertainment device (e.g., music device, video device, satellite radio, etc.), vehicle component or vehicle sensor, smart meter / sensor, industrial manufacturing equipment, global positioning system device, or any other suitable device configured to communicate over a wireless or wired medium. Some UEs may be considered machine type communication (MTC) devices or evolved MTC (eMTC) devices. MTC UEs and eMTC UEs include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, a location tag, etc., that may communicate with a BS, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices, which may be narrowband IoT (NB-IoT) devices.
[0090] In some examples, access to the air interface may be scheduled. A scheduling entity (e.g., a BS) allocates resources for communication between some or all devices and equipment within its service area or cell. The scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communication, the subordinate entities utilize the resources allocated by the scheduling entity. A base station is not the only entity that may function as a scheduling entity. In some examples, a UE may function as a scheduling entity and schedule resources for one or more subordinate entities (e.g., one or more other UEs), and the other UEs may utilize the resources scheduled by the UE for wireless communication. In some examples, a UE may function as a scheduling entity in a peer-to-peer (P2P) network and / or in a mesh network. In a mesh network example, the UEs may communicate directly with each other in addition to communicating with the scheduling entity.
[0091] The methods disclosed herein comprise one or more steps or actions for achieving the method. The steps and / or actions of the methods may be interchanged with one another. In other words, unless a specific order of steps or actions is specified, the order and / or use of specific steps and / or actions may be modified.
[0092] As used herein, a phrase referring to "at least one of" a list of items refers to any combination of those items, including single members. As an example, "at least one of a, b, or c" is intended to cover a, b, c, ab, ac, bc, and abc, as well as any combination having multiples of the same elements (e.g., aa, aaa, aab, aac, abb, acc, bb, bbb, bbc, cc, and ccc, or a, b, and c in any other order).
[0093] As used herein, the term "determining" encompasses a wide variety of actions. For example, "determining" may include calculating, computing, processing, deriving, investigating, looking up (e.g., looking up in a table, database, or another data structure), ascertaining, and the like. Also, "determining" may include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory), and the like. Also, "determining" may include resolving, selecting, choosing, establishing, and the like.
[0094] The foregoing description is provided to enable any person skilled in the art to practice the various aspects described herein. Various modifications of these aspects will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other aspects. Reference to an element in the singular does not mean "the one and only" unless so expressly stated, but rather "one or more". Unless otherwise stated, the term "several" refers to one or more. All structural and functional equivalents of the elements of the various aspects described throughout this disclosure that are known or that later become known to those skilled in the art are expressly incorporated herein by reference and are encompassed by the claims. Moreover, nothing disclosed herein is made public, regardless of whether such disclosure is expressly set forth in the claims. A claim element is not to be construed under the provisions of 35 U.S.C. 112(f) unless the element is expressly recited using the phrase "means for" or, in the case of a method claim, unless the element is recited using the phrase "step for".
[0095] The various operations of the methods described above may be performed by any suitable means capable of performing the corresponding functions. The means may include various hardware and / or software components and / or modules, including, but not limited to, circuits, digital signal processors (DSPs), application specific integrated circuits (ASICs), or processors (e.g., general-purpose or specially programmed processors). Generally, where there are operations illustrated in the figures, those operations may have corresponding counterpart means-plus-function components with similar numbering.
[0096] The various example logic blocks, modules, and circuits described in connection with this disclosure may be implemented or performed using general purpose processors, DSPs, ASICs, field programmable gate arrays (FPGAs) or other programmable logic devices (PLDs), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but alternatively, the processor may be any commercially available processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.
[0097] When implemented in hardware, an exemplary hardware configuration may comprise a processing system in a wireless node. The processing system may be implemented using a bus architecture. The bus may include any number of interconnected buses and bridges depending on the particular application of the processing system and the overall design constraints. The bus may link various circuits together, including the processor, the machine-readable medium, and the bus interface. The bus interface may be used to connect, among other things, a network adapter to the processing system via the bus. The network adapter may be used to perform the signal processing functions of the PHY layer. In the case of a user terminal (see FIG. 1), a user interface (e.g., keypad, display, mouse, joystick, etc.) may also be connected to the bus. The bus may also link various other circuits, such as timing sources, peripherals, voltage regulators, power management circuits, etc., which are well known in the art and therefore will not be described further. The processor may be implemented using one or more general-purpose and / or special-purpose processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuit configurations capable of executing software. Those skilled in the art will recognize the best way to implement the described functionality for a processing system depending on the particular application and the overall design constraints imposed on the overall system.
[0098] If implemented in software, the functions may be stored on or transmitted over a computer-readable medium as one or more instructions or code. Software shall be broadly construed to mean instructions, data, or any combination thereof, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. Computer-readable media includes both computer storage media and communication media, including any medium that facilitates transfer of a computer program from one place to another. A processor may be responsible for managing the bus and general processing, including the execution of software modules stored on the machine-readable storage medium. A computer-readable storage medium may be coupled to the processor such that the processor can read information from and write information to the storage medium. Alternatively, the storage medium may be integral to the processor. By way of example, the machine-readable medium may include a transmission line, a carrier wave modulated by data, and / or a computer-readable storage medium having instructions stored thereon separate from the wireless node, all of which may be accessed by the processor through a bus interface. Alternatively or additionally, the machine-readable medium, or any portion thereof, may be integrated into the processor, such as possibly with a cache and / or a general-purpose register file. Examples of machine-readable storage media may include, by way of example, a RAM (random access memory), a flash memory, a ROM (read-only memory), a PROM (programmable read-only memory), an EPROM (erasable programmable read-only memory), an EEPROM (electrically erasable programmable read-only memory), a register, a magnetic disk, an optical disk, a hard drive, or any other suitable storage medium, or any combination thereof. The machine-readable medium may be embodied in a computer program product.
[0099] A software module may comprise a single instruction or many instructions and may be distributed across several different code segments, among different programs, and across multiple storage media. A computer-readable medium may comprise several software modules. A software module includes instructions that, when executed by a device such as a processor, cause a processing system to perform various functions. A software module may include a transmitting module and a receiving module. Each software module may reside in a single storage device or may be distributed across multiple storage devices. As an example, a software module may be loaded into RAM from a hard drive when a trigger event occurs. During execution of a software module, a processor may load some of the instructions into a cache to increase access speed. One or more cache lines may then be loaded into a general-purpose register file for execution by the processor. When referring to a function of a software module below, it will be understood that such function is implemented by a processor upon executing instructions from that software module.
[0100] Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared (IR), radio, and microwave, the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of medium. As used herein, disk and disc include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Blu-ray disc, where disks typically reproduce data magnetically and discs reproduce data optically using lasers. Thus, in some aspects computer-readable medium may comprise non-transitory computer-readable medium (e.g., tangible media). Additionally, in other aspects, computer readable medium may comprise transitory computer readable medium (e.g., a signal). Combinations of the above may also be considered examples of computer readable media.
[0101] Accordingly, some aspects may comprise a computer program product for performing the operations presented herein. For example, such a computer program product may comprise a computer-readable medium having instructions stored (and / or encoded) thereon, the instructions being executable by one or more processors to perform the operations described herein, e.g., instructions for performing the operations described herein and illustrated in FIG. 7 and / or FIG. 8.
[0102] It should further be appreciated that modules and / or other suitable means for performing the methods and techniques described herein may be downloaded and / or otherwise obtained by a user terminal and / or base station, where applicable. For example, such devices may be coupled to a server to facilitate the transfer of means for performing the methods described herein. Alternatively, the various methods described herein may be provided via a storage means (e.g., RAM, ROM, physical storage medium such as a compact disk (CD) or floppy disk, etc.) from which the user terminal and / or base station may obtain the various methods upon coupling or providing the storage means to the device. Moreover, any other suitable technique for providing the methods and techniques described herein to a device may be utilized.
[0103] It should be understood that the claims are not limited to the precise configuration and components illustrated above. Various modifications, changes and variations may be made in the arrangement, operation and details of the methods and apparatus described above. [Explanation of symbols]
