The entire contents of the above two applications are hereby expressly incorporated by reference into this application as if fully set forth herein and for all applicable purposes, and are assigned to the assignee of this application accordingly. Technical Field

[0003] Aspects of the present disclosure relate to wireless communication, and more particularly, aspects of the present disclosure relate to techniques for controlling signaling. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasting, etc. These wireless communication systems may employ multiple access technologies that are capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). By way of example, examples of such multiple access systems include the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) system, the Enhanced LTE (LTE - A) system, the Code Division Multiple Access (CDMA) system, the Time Division Multiple Access (TDMA) system, the Frequency Division Multiple Access (FDMA) system, the Orthogonal Frequency Division Multiple Access (OFDMA) system, the Single - Carrier Frequency Division Multiple Access (SC - FDMA) system, and the Time Division Synchronous Code Division Multiple Access (TD - SCDMA) system.

[0005] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at the urban, national, regional, and even global levels. New Radio (e.g., 5G NR) is an example of an emerging telecommunication standard. NR is an enhanced set of the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing costs, enhancing services, leveraging new spectrums, and using OFDMA with cyclic prefix (CP) on the downlink (DL) and on the uplink (UL) to better integrate with other open standards. To this end, NR supports beamforming, multiple - input multiple - output (MIMO) antenna technology, and carrier aggregation.

[0006] However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in NR and LTE technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies. Summary of the Invention

[0028] Certain aspects of the present disclosure provide apparatuses, methods, processing systems, and computer-readable media for controlling signaling. For example, downlink control information (DCI) (also referred to as piggybacked DCI) may be transmitted (e.g., piggybacked on) using resources of a data channel (e.g., physical downlink shared channel (PDSCH)), which is configured using semi-persistent scheduling (SPS) (also referred to as SPS PDSCH). Transmitting DCI using a data channel configured with SPS improves communication robustness.

[0029] In certain aspects, DCI in a data channel may allocate resources for monitoring reception of another data channel, other DCI in the data channel, or an open control channel (e.g., physical downlink control channel (PDCCH)) opportunity, as described in more detail herein. In one or more examples, the techniques described herein may be applicable to carrier aggregation (CA). For example, piggybacked DCI may be transmitted on a component carrier (CC), and resources for transmitting signaling (e.g., PDSCH) on different CCs may be allocated.

[0030] The following description provides examples of control signaling in a communication system without limiting the scope, applicability, or examples set forth in the claims. Changes may be made in the functionality and arrangement of the elements discussed without departing from the scope of the present disclosure. Various processes or components may be omitted, replaced, or added as appropriate for each example. For example, the methods described may be performed in an order different from that described, and various steps may be added, omitted, or combined. Additionally, features described with respect to some examples may be combined into some other examples. For example, an apparatus may be implemented or a method may be practiced using any number of aspects set forth herein. Moreover, the scope of the present disclosure is intended to cover such apparatuses or methods implemented using other structures, functions, or a combination of structures and functions in addition to or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be embodied by one or more elements of the claims. The term “exemplary” as used herein means “serving as an example, instance, or illustration.” Any aspect described herein as “exemplary” is not necessarily to be construed as preferred or having an advantage over other aspects.

[0031] In general, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies. The RAT can also be referred to as radio technology, air interface, etc. The frequency can also be referred to as carrier, sub-carrier, frequency channel, tone, sub-band, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks with different RATs. In some cases, a 5G NR RAT network can be deployed.

[0032] Figure 1 FIG. 4 shows an example wireless communication network 100 in which aspects of the present disclosure may be implemented. For example, the wireless communication network 100 can be an NR system (e.g., a 5G NR network).

[0033] As Figure 1 shown, the wireless communication network 100 can include multiple base stations (BSs) 110a-z (each of which is also referred to herein individually as a BS 110 or collectively as BS 110) and other network entities. The BS 110 can provide communication coverage for a specific geographical area (sometimes referred to as a "cell"), which can be fixed or can move according to the location of the mobile BS 110. In some examples, the BS 110 can use any suitable transport network to interconnect with each other and / or with one or more other BSs or network nodes (not shown) in the wireless communication network 100 through various types of backhaul interfaces (e.g., direct physical connections, wireless connections, virtual networks, etc.). In Figure 1 the example shown, BSs 110a, 110b, and 110c can be macro BSs for macro cells 102a, 102b, and 102c, respectively. BS 110x can be a pico BS for pico cell 102x. BSs 110y and 110z can be femto BSs for femto cells 102y and 102z, respectively. A BS can support one or more cells. The BS 110 communicates with user equipment (UEs) 120a-y (each of which is also referred to herein individually as a UE 120 or collectively as UEs 120) in the wireless communication network 100. The UEs 120 (e.g., 120x, 120y, etc.) can be dispersed throughout the wireless communication network 100, and each UE 120 can be fixed or mobile.

[0034] According to certain aspects, the BS 110 and the UE 120 can be configured to transmit downlink control information (DCI) carried on a semi-persistent scheduling (SPS) PDSCH. As Figure 1As shown in, BS 110a includes a control signaling manager 111. According to aspects of the present disclosure, the control signaling manager 111 may be configured to use resources in the SPS PDSCH to transmit DCI. As Figure 1 As shown in, UE 120a includes a control signaling manager 121. According to aspects of the present disclosure, the control signaling manager 121 may be configured to receive DCI carried on the SPS PDSCH.

[0035] The wireless communication network 100 may further include a relay station (e.g., relay station 110r) (which is also referred to as a repeater, etc.), which receives transmissions of data and / or other information from an upstream station (e.g., BS 110a or UE 120r) and transmits the transmissions of data and / or other information to a downstream station (e.g., UE 120 or BS 110), or relays transmissions between UE 120s to facilitate communication between devices.

[0036] The network controller 130 may be coupled to a group of BSs 110 and provide coordination and control for these BSs 110. The network controller 130 may communicate with the BSs 110 via a backhaul. The BSs 110 may also communicate with each other (e.g., directly or indirectly) via a wireless or wired backhaul.

[0037] Figure 2 Examples of components of BS 110a and UE 120a are shown (e.g., in Figure 1 the wireless communication network 100) that may be used to implement aspects of the present disclosure.

[0038] At 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 used for physical broadcast channel (PBCH), physical control format indicator channel (PCFICH), physical hybrid ARQ indicator channel (PHICH), PDCCH, group common PDCCH (GC PDCCH), etc. The data may be used for PDSCH, etc. The processor 220 may process (e.g., encode and symbol map) the data and control information respectively to obtain data symbols and control symbols. The processor 220 may also generate reference symbols for, e.g., primary synchronization signal (PSS), secondary synchronization signal (SSS), and cell-specific reference signal (CRS). 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 an output symbol stream to the modulators (MOD) 232a - 232t. Each modulator 232 may process the corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signals from the modulators 232a - 232t may be transmitted via the antennas 234a - 234t respectively.

[0039] At UE 120a, the antennas 252a - 252r may receive the downlink signals from BS 110a, and may provide the received signals to the demodulators (DEMOD) 254a - 254r in the transceiver respectively. Each demodulator 254 may condition (e.g., filter, amplify, down-convert, and digitize) the corresponding received signal to obtain input samples. Each demodulator may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 256 may obtain the received symbols from all the demodulators 254a - 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. The receive processor 258 may process (e.g., demodulate, de-interleave, and decode) the detected symbols, provide the decoded data for UE 120a to the data sink 260, and provide the decoded control information to the controller / processor 280.

[0040] On the uplink, at the UE 120a, the transmit processor 264 may receive and process data from the data source 262 (e.g., for the Physical Uplink Shared Channel (PUSCH)) and control information from the controller / processor 280 (e.g., for the Physical Uplink Control Channel (PUCCH)). The transmit processor 264 may also generate reference symbols for reference signals (e.g., for the Sounding Reference Signal (SRS)). Symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266 (if applicable), further processed by the demodulators 254a - 254r in the transceiver (e.g., for SC - FDM, etc.), and transmitted to the BS 110a. At the BS 110a, the uplink signal from the UE 120a may be received by the antenna 234, processed by the modulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 120a. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240.

[0041] 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 the UE for data transmission on the downlink and / or uplink.

[0042] The controller / processor 280 and / or other processors and modules at the UE 120a may execute or direct the execution of processes for the techniques described herein. For example, as Figure 2 shown, the controller / processor 240 of the BS 110a has a control signaling manager 241, which, in accordance with the aspects described herein, may be configured to transmit DCI using resources on the SPS PDSCH. As Figure 2 shown, the controller / processor 280 of the UE 120a has a control signaling manager 241, which, in accordance with the aspects described herein, may be configured to receive DCI using resources on the SPS PDSCH. Although shown at the controller / processor, other components of the UE 120a and the BS 110a may be used to perform the operations described herein.

[0043] In some implementations, beamforming can be used to improve communication efficiency. When beamforming is implemented, the antenna array can be controlled to transmit radio signals in a specific direction. The antenna array using beamforming transmits / receives a relatively strong beam of signals in a specific direction. To implement beamforming, a separate signal to be transmitted can be provided to each antenna element. The phase and amplitude of each signal can be controlled such that the signals transmitted by the antenna elements are added constructively and destructively so that they concentrate the signals into a narrow beam or lobe.

[0044] Example techniques for transmitting DCI carried on SPS PDSCH

[0045] In certain implementations, downlink control information (DCI) can be transmitted on the physical downlink shared channel (PDSCH) (also known as the data channel). Compared to lower frequency bands (such as frequency range (FR) 1 and FR2), higher communication frequency bands (such as the 60 GHz band) may have a relatively short slot duration, for example, due to the higher subcarrier spacing (SCS) associated with the higher frequency band (e.g., 960 kHz, 1.92 MHz, 3.84 MHz). Therefore, the number of physical downlink control channel (PDCCH) monitoring opportunities may increase, resulting in high power consumption. Due to the short slot duration and narrow analog beamforming transmission on the higher frequency band, the opportunity to send multiple DCIs to different UEs is reduced compared to FR1 / FR2. Alternatively, the BS (e.g., gNB) is more likely to send multiple DCIs to the same UE (e.g., especially for "burst" traffic). Therefore, DCI can be transmitted on the data channel to reduce the control channel monitoring density for better micro-sleep scheduling at the UE, thereby reducing power consumption.

[0046] In some cases, the DCI in the control resource set (CORESET) (referred to as DCI CORESET ) can be transmitted in a frame together with one or more DCIs (referred to as DCI CORESET ) in the PDSCH assigned by DCI PDSCH . In other words, DCI CORESET can include the allocation information for DCI PDSCH , and in some cases, also includes the common part of multiple DCIs PDSCH . In some implementations, DCI CORESET can indicate a regular grant (e.g., of another PDSCH). Additionally, each DCI PDSCH in one or more DCIs PDSCH can indicate a regular grant (e.g., of another PDSCH).

[0047] In some cases, a UE may implement intermittent PDCCH monitoring. In other words, the UE may monitor the PDCCH only in a portion of the time slots in a frame, thereby reducing power conversion at the UE. In one or more examples, compared to the PDSCH, a wider or same-sized beam may be utilized to transmit the PDCCH, resulting in a low beamforming gain. Additionally, the PDCCH density in the CORESET may be high, resulting in a high complexity for blind decoding by the UE. As described herein, the DCI in the PDCCH may indicate resources for receiving one or more DCIs (also referred to as piggybacked DCIs) in the PDSCH. If the UE does not detect the first DCI in the PDCCH (e.g., DCI CORESET ), the UE may not be able to decode all corresponding piggybacked DCIs (DCI PDSCH ).

[0048] In certain aspects of the present disclosure, one or more DCIs in a PDSCH configured using semi-persistent scheduling (SPS) may be transmitted to improve communication robustness. For example, the PDSCH may be configured (e.g., via radio resource control (RRC) signaling) and activated by SPS, and may be used to convey DCIs for allocating resources in other channels. Once the SPS is successfully activated (e.g., via a DCI in a control channel), the UE may decode the PDSCH including one or more DCIs PDSCH thereby improving communication robustness.

[0049] Figure 3 is a flowchart illustrating an example operation 300 for wireless communication in accordance with certain aspects of the present disclosure. Operation 300 may be performed, for example, by a BS (e.g., such as BS 110a in the wireless communication network 100).

[0050] Operation 300 may be implemented as a software component executed and run on one or more processors (e.g., Figure 2 the controller / processor 240). Additionally, the transmission and reception of signals by the BS in operation 300 may be implemented, for example, by one or more antennas (e.g., Figure 2 the antenna 234). In certain aspects, the transmission and / or reception of signals by the BS may be implemented via a bus interface of one or more processors (e.g., the controller / processor 240) for obtaining and / or outputting signals.

[0051] At block 305, operation 300 may begin by sending a message (e.g., an RRC message) having a configuration for semi-persistent scheduling (SPS) for a data channel (e.g., PDSCH). At block 310, the BS may send an indication associated with at least one first DCI for transmission in at least one of the data channels in the data channel. In some aspects, the configuration associated with the at least one first DCI may be part of a message having a configuration for SPS for the data channel.

[0052] In some aspects, the BS may send a second DCI on a control channel, the second DCI activating the configuration for SPS for the data channel. In some implementations, the second DCI, the message, or a combination thereof may indicate the configuration associated with the at least one first DCI. At block 315, the BS may generate a data channel according to the configuration for SPS, and at block 320, send at least one of the data channels in the data channel. In some aspects, at least one of the data channels in the data channel (e.g., SPS PDSCH) may include at least one first DCI, and the at least one first DCI may indicate resources allocated for at least one other data channel (e.g., PDSCH). The BS may send the at least one other data channel via the resources indicated by the at least one first DCI.

[0053] Figure 4 is a flow chart illustrating an example operation 400 for wireless communication in accordance with some aspects of the present disclosure. Operation 400 may be performed, for example, by a UE (e.g., UE 120a in wireless communication network 100 such as).

[0054] Operation 400 may be implemented as a software component executed and run on one or more processors (e.g., Figure 2 the controller / processor 280). Additionally, the transmission and reception of signals by the UE in operation 400 may be implemented, for example, via one or more antennas (e.g., Figure 2 the antenna 252). In some aspects, the transmission and / or reception of signals by the UE may be implemented via a bus interface of one or more processors (e.g., the controller / processor 280) for obtaining and / or outputting signals.

[0055] At block 405, operation 400 may begin by receiving a message (e.g., an RRC message) having a configuration for semi-persistent scheduling (SPS) of a data channel (e.g., PDSCH, also referred to as SPS PDSCH). In some aspects, the UE may also receive a second DCI on a control channel, the second DCI activating the configuration for the SPS of the data channel. At block 410, the UE may receive an indication associated with at least one first DCI (also referred to as piggybacked DCI) for transmission in at least one of the data channels in the data channel. In some aspects, the configuration associated with the at least one first DCI may be part of a message having a configuration for the SPS of the data channel.

[0056] In some aspects, the UE may receive a second DCI on a control channel, the second DCI activating the configuration for the SPS of the data channel. In some cases, the second DCI, the message, or a combination thereof indicates the configuration associated with the at least one first DCI. At block 415, the UE may monitor the data channel according to the configuration for the SPS. In some aspects, the UE may receive at least one data channel (e.g., SPS PDSCH) in the data channel having at least one first DCI. The at least one first DCI may indicate resources allocated for at least one other data channel (e.g., PDSCH). The UE may receive the at least one other data channel via the resources indicated by the at least one first DCI.

[0057] Figure 5A and 5B each illustrate a frame 500 including a piggybacked DCI in an SPS-configured PDSCH (also referred to as SPS PDSCH) according to some aspects of the present disclosure. As shown, frame 500 may include a plurality of time slots, each time slot having a PDCCH monitoring occasion (e.g., PDCCH monitoring occasion 506). The UE may monitor PDCCH 504 to receive DCI 502. As shown, the UE may skip monitoring PDCCH monitoring occasions in respective time slots, such as PDCCH monitoring occasion 506. DCI 502 may activate the configured SPS PDSCHs 510, 512, 514. Each of SPS PDSCHs 510, 512, 514 may include one or more piggybacked DCIs (e.g., DCIs transmitted on the SPS PDSCH). For example, each of PDSCHs 510, 512, 514 may be configured with resources 520, 522, 524 in which the piggybacked DCI may be transmitted.

[0058] As Figure 5BAs shown, resource 520 may include an on-carrier DCI 530, resource 522 may include an on-carrier DCI 532, and resource 524 may include an on-carrier DCI 534. In some implementations, each of the on-carrier DCIs may schedule resources for the UE to receive a PDSCH. For example, DCI 540 may schedule resources for PDSCH 550, DCI 542 may schedule resources for PDSCH 552, DCI 544 may schedule resources for PDSCH 554, and DCI 546 may schedule resources for PDSCH 556.

[0059] In some cases, there may already be SPS data to be transmitted in the PDSCH in which the on-carrier DCI is to be sent. In other words, SPS may be configured via RRC signaling, and the SPS PDSCH may be configured for a specific type of data (e.g., also referred to as SPS data) such as voice data. The on-carrier DCI may be sent concurrently with the SPS data in the SPS PDSCH.

[0060] In some aspects, the information (e.g., configuration) assigned by the on-carrier DCI (e.g., resource allocation, number of on-carrier DCIs, modulation and coding scheme (MCS), etc.) may be included in the SPS configuration RRC message, the SPS activation DCI (e.g., DCI 502), or a combination of both (e.g., some information may be in the RRC message and other information may be in the DCI). For example, a table consisting of several candidates (also referred to as configuration candidates) for the on-carrier DCI region (e.g., different sizes and lengths) may be included in the SPS configuration RRC message. The information for the on-carrier DCI region may be indicated by a table index in the activation DCI. In other words, multiple candidate configurations for the on-carrier DCI may be indicated in the RRC message, and the activation DCI (e.g., DCI 502) in the PDCCH may select the configuration by indicating an index associated with one of the candidate configurations.

[0061] In some aspects, the SPS configuration RRC message may configure one region in the SPS PDSCH for the on-carrier DCI. Whether to send the on-carrier DCI in this region may be indicated by the SPS activation DCI (e.g., DCI 502).

[0062] In some aspects, the size of the carried DCI region (e.g., resource 520) indicated by configuration or activation may represent a maximum value. The actual size of the assigned carried DCI region (e.g., the size of the resources consumed by DCI 540, 542, 544, 546) may vary over time and be different from the value indicated by the RRC or DCI. In some aspects, zero-padding may be used to fill the remaining portion of the resource (e.g., resource 520) that is not used for the carried DCI (e.g., DCI 540, 542, 544, 546). In some aspects, the rate matching and transport block size (TBS) calculation for SPS data in the PDSCH (e.g., PDSCH 510) may be based on the maximum size indicated by the RRC or DCI.

[0063] In some cases, there may be no SPS data in the PDSCH (e.g., PDSCH 510) in which the carried DCI is transmitted. In such a case, the carried DCI is transmitted only in the SPS PDSCH (e.g., without a downlink (DL)-shared channel (DL-SCH)). In such a case, the RRC message or DCI (e.g., DCI 502) may indicate whether only the DCI is included in the PDSCH without a DL-SCH. It is also possible to allocate any type of data (i.e., transmit data concurrently with the DCI) in the PDSCH assigned by SPS. In other words, other types of data (e.g., voice data) different from the SPS data may be transmitted in the PDSCH (e.g., PDSCH 510).

[0064] In some aspects, a single (or a small fixed number N) DCI may be assigned in the SPS PDSCH. The assigned DCI may be used to open PDCCH monitoring opportunities or indicate the resources to which one or more carried DCIs are allocated, as described in more detail herein. If only one (or a small fixed number N) DCI is assigned in the SPS PDSCH, the TBS calculation for the data in the PDSCH can be performed efficiently (e.g., reducing waste of resources).

[0065] Figure 6FIG. 600 shows a frame with a single DCI in SPS PDSCH according to certain aspects of the present disclosure. For example, DCI 502 may activate SPS PDSCH 510 with resources 520. However, DCI may not be assigned to resources 520. In some cases, DCI (e.g., DCI 602) may be assigned in the resources of SPS PDSCH (e.g., PDSCH 604). DCI 602 may open a PDCCH monitoring occasion that would otherwise not be monitored by the UE. In other words, DCI 602 may indicate to the UE to monitor PDCCH 606. In certain aspects, DCI (e.g., DCI 608) may be assigned in the resources of SPS PDSCH (e.g., PDSCH 610). DCI 608 may indicate resources in PDSCH 610 to which multiple piggybacked DCIs 612 are assigned and are to be monitored by the UE. As shown, each of the piggybacked DCIs 612 may assign resources for PDSCHs 614, 616, 618, 620.

[0066] Figure 7 FIG. shows a piggybacked DCI that allocates PDSCH resources for carrier aggregation (CA). As shown, the piggybacked DCI in resources 520 on a component carrier (e.g., CC#0) may indicate resources that are assigned for PDSCHs (e.g., PDSCHs on different component carriers (e.g., CC#1 and CC#2)). For example, the piggybacked DCI may indicate resources that are assigned for PDSCHs 702, 704 on CC#1 and PDSCHs 706, 708 on CC#2.

[0067] As shown, a physical uplink control channel (PUCCH) 710 may be transmitted by the UE with a hybrid automatic repeat request (HARQ) acknowledgment (ACK) codebook 712. As shown, codebook 712 indicates ACK or negative ACK (NACK) (A / N) for PDSCHs 510, 702, 704, 706, 708, 720, 722, 724, 726 assigned to the UE, as shown. For example, for K 1 (PDSCH to HARQ timing indicator)=1 in codebook 712, the UE indicates A / N for PDSCHs 726, 708, and for K 1 =2 in codebook 712, the UE indicates A / N for PDSCHs 724, 704, and so on.

[0068] In some cases, the carried DCI can indicate the resources of the PDSCH on a subset of CCs allocated for configuration. For example, the carried DCI in resource 522 can indicate the resources of the PDSCH allocated for CC#0 and CC#2, while there are no resources on CC#1. Thus, based on the carried DCI, the UE can refrain from monitoring CC#1, resulting in UE power savings, and can refrain from feeding back HARQ A / N for CC#1 via the codebook 732 in PUCCH730 (reducing signaling overhead). Similarly, the carried DCI in resource 524 can indicate the resources of the PDSCH allocated for CC#0 and CC#1, while there are no resources on CC#2. Thus, based on the carried DCI, the UE can refrain from monitoring CC#2, resulting in UE power savings, and can refrain from feeding back HARQ A / N for CC#2 via the codebook 734 in PUCCH736.

[0069] In certain aspects of the present disclosure, the carried DCI or the DCI in the PDCCH can be used to allocate the PDSCH740. For example, the PDSCH 740 can be in the same time slot as the PDSCH 516 and can be semi-statically assigned by the SPS activation DCI (e.g., DCI 502) in the CORESET (e.g., PDCCH504) of CC#0. As another example, by setting the parameter K 0 =0, the PDSCH740 can be dynamically assigned by the DCI on the SPS PDSCH 516 (e.g., the carried DCI in resource 524).

The terms “network” and “system” are often used interchangeably. CDMA networks may implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. cdma2000 covers the IS-2000, IS-95, and IS-856 standards. TDMA networks may implement radio technologies such as Global System for Mobile Communications (GSM). OFDMA networks may implement radio technologies such as NR (e.g., 5G RA), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are part of 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 communication technology under development.

[0128] The techniques described herein can be used for the wireless networks and radio technologies mentioned above and other wireless networks and radio technologies. For clarity, although terms commonly associated with 3G, 4G, and / or 5G wireless technologies may be used herein to describe aspects, aspects of the present disclosure can be applied to communication systems based on other generations.

[0129] In 3GPP, the term "cell" can refer to the coverage area of a Node B (NB) and / or the NB subsystem serving that 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 gNodeB), access point (AP), distributed unit (DU), carrier, or transmit receive point (TRP) can be used interchangeably. A BS can provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell can cover a relatively large geographical area (e.g., with a radius of several kilometers) and can allow unrestricted access by UEs with a service subscription. A pico cell can cover a relatively small geographical area and can allow unrestricted access by UEs with a service subscription. A femto cell can cover a relatively small geographical area (e.g., a residence) and can allow restricted access by UEs associated with that femto cell (e.g., UEs in a closed subscriber group (CSG), UEs for users in a residence, etc.). The BS for a macro cell can be referred to as a macro BS. The BS for a pico cell can be referred to as a pico BS. The BS for a femto cell can be referred to as a femto BS or a home BS.

[0130] 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 apparatus, biometric sensor / device, wearable device (such as a smartwatch, 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 unit, etc.), vehicle component or sensor, smart meter / sensor, industrial manufacturing device, global positioning system device, or any other suitable device configured to communicate via a wireless medium or a wired medium. Some UEs may be considered machine type communication (MTC) devices or evolved MTC (eMTC) devices. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a BS, another device (e.g., a remote device), or some other entity. A wireless node may provide a connection to or for a network (e.g., a wide area network such as the Internet or a cellular network) via a wired communication link or a wireless communication link. Some UEs may be considered Internet of Things (IoT) devices, which may be narrowband IoT (NB-IoT) devices.

[0131] Some wireless networks (e.g., LTE) utilize Orthogonal Frequency Division Multiplexing (OFDM) on the downlink and Single Carrier Frequency Division Multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are often also referred to as tones, frequency bands, etc. Each subcarrier can be modulated with data. Typically, OFDM is utilized in the frequency domain and SC-FDM is utilized in the time domain to transmit modulation symbols. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. For example, the subcarrier spacing can be 15 kHz and the minimum resource allocation (referred to as a "resource block" (RB)) can be 12 subcarriers (or 180 kHz). Thus, for system bandwidths of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), the nominal Fast Fourier Transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048, respectively. The system bandwidth can also be divided into subbands. For example, a subband can cover 1.8 MHz (e.g., 6 RBs), and for system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz, there can be 1, 2, 4, 8, or 16 subbands, respectively. In LTE, the basic transmission time interval (TTI) or packet duration is a 1 ms subframe.

[0132] NR can utilize OFDM with CP on both the uplink and downlink and can include support for half-duplex operation using TDD. In NR, the subframe is still 1 ms, but the basic TTI is referred to as a slot. A subframe contains a variable number of slots (e.g., 1, 2, 4, 8, 16... slots), which depends on the subcarrier spacing. An NR RB is 12 consecutive frequency subcarriers. NR can support a basic subcarrier spacing of 15 kHz, and other subcarrier spacings can be defined relative to the basic subcarrier spacing, e.g., 30 kHz, 60 kHz, 120 kHz, 240 kHz, etc. The symbol and slot lengths scale with the subcarrier spacing. The CP length also depends on the subcarrier spacing. Beamforming can be supported and the beam direction can be configured dynamically.

[0133] MIMO transmission with precoding can also be supported. In some examples, the MIMO configuration in the DL can support up to 8 transmit antennas, where multi-layer DL transmission is up to 8 streams and up to 2 streams per UE. In some examples, multi-layer transmission with up to 2 streams per UE can be supported. Aggregation of multiple cells with up to 8 serving cells can be supported.

[0134] In some examples, access to the air interface can be scheduled. A scheduling entity (e.g., a BS) allocates resources for communication among some or all of the devices and apparatuses within its serving area or cell. The scheduling entity can be responsible for scheduling, allocating, reconfiguring, and releasing resources for one or more subordinate entities. That is, for a scheduled communication, the subordinate entity utilizes the resources allocated by the scheduling entity. A base station is not the only entity that can be used as a scheduling entity. In some examples, a UE can be used as a scheduling entity and can schedule resources for one or more subordinate entities (e.g., one or more other UEs), and the other UEs can utilize the resources scheduled by the UE for wireless communication. In some examples, a UE can be used as a scheduling entity in a peer-to-peer (P2P) network and / or a mesh network. In a mesh network example, in addition to communicating with the scheduling entity, UEs can also communicate directly with each other.

[0135] In some examples, two or more subordinate entities (e.g., UEs) can communicate with each other using sidelink signals. Real-life applications of such sidelink communication can include public safety, proximity services, UE-to-network relay, vehicle-to-vehicle (V2V) communication, Internet of Everything (IoE) communication, IoT communication, mission-critical mesh, and / or various other suitable applications. Generally, a sidelink signal can refer to a signal transmitted from one subordinate entity (e.g., UE1) to another subordinate entity (e.g., UE2) without the need to relay the communication through a scheduling entity (e.g., a UE or a BS), even though the scheduling entity can be used for scheduling and / or control purposes. In some examples, licensed spectrum can be used to transmit sidelink signals (different from wireless local area networks that typically use unlicensed spectrum).

[0136] The electromagnetic spectrum is generally subdivided into various categories, frequency bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating frequency bands have been identified as the frequency range names FR1 (410 MHz – 7.125 GHz) and FR2 (24.25 GHz – 52.6 GHz). It should be understood that although a part of FR1 is greater than 6 GHz, in various documents and articles, FR1 is generally (interchangeably) referred to as the “sub-6 GHz” band. Similar naming issues sometimes occur with respect to FR2, which is generally (interchangeably) referred to as the “millimeter wave” band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz – 300 GHz), and the EHF band is identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0137] The frequency between FR1 and FR2 is generally referred to as the mid-band frequency. Recent 5G NR research has identified the operating bands for these mid-band frequencies as the frequency range name FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics and, thus, can effectively extend the features of FR1 and / or FR2 to the mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as the frequency range names FR4a or FR4-1 (52.6 GHz – 71 GHz), FR4 (52.6 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0138] In view of the above aspects, unless otherwise specifically stated, it should be understood that if terms such as "below 6 GHz" are used herein, they can generally represent frequencies that can be less than 6 GHz, can be within FR1, or can include mid-band frequencies. Additionally, unless otherwise specifically stated, it should be understood that if terms such as "millimeter wave" are used herein, they can generally represent frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or can be within the EHF band.

[0139] The methods disclosed herein include one or more steps or actions for implementing the method. Without departing from the scope of the claims, these method steps and / or actions can 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 can be modified without departing from the scope of the claims.

[0140] As used herein, the phrase referring to "at least one" of a list of items refers to any combination of those items (including a single member). By way of example, "at least one of a, b, or c" is intended to cover a, b, c, a-b, a-c, b-c, and a-b-c, as well as any combination with multiples of the same element (e.g., a-a, a-a-a, a-a-b, a-a-c, a-b-b, a-c-c, b-b, b-b-b, b-b-c, c-c, and c-c-c or any other ordering of a, b, and c).

Various modifications to these aspects will be readily apparent to those skilled in the art, and the general principles defined herein can be applied to other aspects. Thus, the claims are not intended to be limited to the aspects shown herein, but are to be accorded the full scope consistent with the language of the claims, wherein the use of the singular form of an element is not intended to mean "one and only one" unless specifically so stated, but rather "one or more". The term "some" refers to one or more unless specifically stated otherwise. All structural and functional equivalents of the elements of the various aspects described throughout this disclosure are expressly incorporated herein by reference and are intended to be encompassed by the claims, which are known or will be known to those of ordinary skill in the art. Further, nothing disclosed herein is intended to be dedicated to the public, whether or not such disclosure is expressly recited in the claims. No claim element is 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, the phrase "step for".

[0143] The various operations of the methods described above can be performed by any suitable unit capable of performing the corresponding functions. These units can include a variety of hardware and / or software components and / or modules, including but not limited to: circuits, application specific integrated circuits (ASICs), or processors. Generally, where there are operations shown in the figures, those operations can have corresponding paired units plus functional components with similar numbers.

[0144] The various illustrative logical blocks, modules, and circuits described in connection with the present disclosure may be implemented or performed using a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device (PLD), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but in the alternative, the processor may be any commercially available processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.

[0145] If implemented in hardware, an example hardware configuration may include a processing system in a wireless node. The processing system may be implemented using a bus architecture. Depending on the particular application and overall design constraints of the processing system, the bus may include any number of interconnecting buses and bridges. The bus may couple together various circuits including a processor, machine-readable media, and a bus interface. In addition, the bus interface may be used to couple a network adapter to the processing system via the bus. The network adapter may be used to implement the signal processing functions of the PHY layer. In the case of the user terminal 120 (see Figure 1 ), a user interface (e.g., keypad, display, mouse, joystick, etc.) may also be coupled to the bus. The bus may also couple various other circuits such as a timing source, peripherals, voltage regulators, power management circuits, etc., which are well known in the art and will not be described further herein. The processor may be implemented using one or more general purpose processors and / or special purpose processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuits that can execute software. Those skilled in the art will recognize how best to implement the described functions for the processing system in light of the particular application and overall design constraints imposed on the overall system.

[0146] If implemented in software, the functions may be stored on or transmitted via a computer-readable medium as one or more instructions or code. Whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise, software shall be construed broadly to mean any combination of instructions, data, or both. A computer-readable medium includes both a computer storage medium and a communication medium, where the communication medium includes any medium that facilitates transfer of a computer program from one place to another. A processor may be responsible for managing a bus and general processing, which includes executing software modules stored on a machine-readable storage medium. The 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. In an alternative, the storage medium may be integral to the processor. By way of example, a machine-readable medium may include a transmission line, a carrier modulated with data, and / or a computer-readable storage medium with instructions stored thereon separate from a wireless node, all of which may be accessed by the processor via a bus interface. Alternatively or additionally, any part of the machine-readable medium or all of it may be integrated into the processor, such as may be the case with a cache and / or a general register file. By way of example, examples of a machine-readable medium may include RAM (Random Access Memory), flash memory, ROM (Read-Only Memory), PROM (Programmable Read-Only Memory), EPROM (Erasable Programmable Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), registers, magnetic disks, optical disks, hard drives, or any other suitable storage medium, or any combination thereof. A machine-readable medium may be embodied in a computer program product.

[0147] Software modules may include a single instruction or many instructions and may be distributed across several different code segments, in different programs, and across multiple storage media. A computer-readable medium may include several software modules. Software modules include instructions that, when executed by a device such as a processor, cause a processing system to perform various functions. Software modules may include a sending module and a receiving module. Each software module may reside in a single storage device or be distributed across multiple storage devices. By way of example, when a triggering event occurs, a software module may be loaded from a hard drive into RAM. During execution of a software module, the processor may load some of the instructions into a cache to increase access speed. Subsequently, one or more cache lines may be loaded into a general register file for execution by the processor. When referring to the functions of a software module hereinafter, it will be understood that such functions are implemented by the processor when executing instructions from the software module.

[0148] In addition, any connection is properly termed a computer-readable medium. For example, if 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, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of the 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, while discs use lasers to optically reproduce data. Thus, in some aspects, computer-readable media can include non-transitory computer-readable media (e.g., tangible media). Additionally, for other aspects, computer-readable media can include transitory computer-readable media (e.g., signals). The above combinations should also be included within the scope of computer-readable media.

[0149] Accordingly, some aspects can include a computer program product for performing the operations given herein. For example, such a computer program product can include 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.

[0150] Furthermore, it should be appreciated that modules and / or other suitable units for performing the methods and techniques described herein can be downloaded and / or otherwise obtained by a user terminal and / or a base station where applicable. For example, such devices can be coupled to a server to facilitate the transfer of units for performing the methods described herein. Alternatively, the various methods described herein can be provided via a storage unit (e.g., RAM, ROM, a physical storage medium such as a compact disc (CD) or floppy disk, etc.) such that the user terminal and / or the base station can obtain the various methods when the storage unit is coupled to or provided to the device. Additionally, any other suitable techniques for providing the methods and techniques described herein to a device can be used.

[0151] It should be understood that the claims are not limited to the exact configurations and components shown above. Various modifications, changes, and variations can be made to the arrangements, operations, and details of the methods and apparatuses described above without departing from the scope of the claims.
