A method that can be performed by a user equipment (UE) includes camping on a first cell associated with a first universal subscriber identity module (USIM), where the UE has the first USIM and a second USIM, receiving a paging message from the first cell, and in response to the paging message, sending a first response message indicating that the UE requests to enter an idle or inactive mode on the first cell.

Description

background Technical Field

[0002] Various aspects of this disclosure relate to wireless communication, and more specifically, to techniques for responding to paging by multiple Universal Subscription Identity Module (Multi-USIM) devices. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone communication, video, data, messaging, and broadcasting. These wireless communication systems can employ multiple access technologies that enable communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access systems include 3GPP Long Term Evolution (LTE) systems, LTE-A Advanced 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.

[0005] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different wireless devices to communicate at the municipal, national, regional, and even global levels. New radios (e.g., 5G NR) are examples of emerging telecommunications standards. NR is a collection of enhancements to the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and better integrating with other open standards using OFDMA with a cyclic prefix (CP) on both the downlink (DL) and uplink (UL). To this end, NR supports beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

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

[0007] The systems, methods, and apparatus of this disclosure each have several aspects, none of which individually assumes responsibility for their desired properties. Without limiting the scope of this disclosure as set forth in the following claims, some features will now be briefly discussed. Upon consideration of this discussion, and particularly after reading the section entitled "Detailed Description," those skilled in the art will understand how the features of this disclosure provide advantages including improved utilization of transmission resources.

[0008] Some aspects provide a method for wireless communication performed by a user equipment (UE). The method generally includes residing on a first cell associated with a first universal subscriber identity module (USIM), wherein the UE has a first USIM and a second USIM; receiving a paging message from the first cell; and in response to the paging message, sending a first response message instructing the UE to request to enter an idle or inactive mode on the first cell.

[0009] Some aspects provide a method for wireless communication performed by a base station (BS). The method generally includes sending a paging message requesting a user equipment (UE) to enter a connected mode on a first cell; in response to the paging message, receiving a first response message indicating that the UE requests to enter an idle or inactive mode on the first cell; and sending a reply to the first response message.

[0010] Some aspects provide an apparatus for wireless communication. The apparatus generally includes a processor configured to reside on a first cell associated with a first Universal Subscriber Identity Module (USIM), wherein the apparatus has a first USIM and a second USIM; receiving a paging message from the first cell; and, in response to the paging message, sending a first response message instructing the apparatus to request to enter an idle or inactive mode on the first cell; and a memory coupled to the processor.

[0011] Some aspects provide an apparatus for wireless communication. The apparatus generally includes a processor configured to transmit a paging message requesting a user equipment (UE) to enter a connected mode on a first cell; in response to the paging message, receive a first response message indicating that the UE requests to enter an idle or inactive mode on the first cell; transmit a reply to the first response message; and a memory coupled to the processor.

[0012] Some aspects provide an apparatus for wireless communication. The apparatus generally includes components for residing on a first cell associated with a first Universal Subscriber Identity Module (USIM), wherein the apparatus has a first USIM and a second USIM; components for receiving a paging message from the first cell; and components for transmitting a first response message in response to the paging message, instructing the apparatus to request to enter an idle or inactive mode on the first cell.

[0013] Some aspects provide an apparatus for wireless communication. The apparatus generally includes components for transmitting a paging message requesting a user equipment (UE) to enter a connected mode on a first cell; components for receiving a first response message in response to the paging message indicating that the UE requests to enter an idle or inactive mode on the first cell; and components for transmitting a reply to the first response message.

[0014] Some aspects provide a computer-readable medium for wireless communication performed by a user equipment (UE). The computer-readable medium includes instructions that, when executed by a processing system of the UE, cause the processing system to perform operations generally including residing on a first cell associated with a first universal subscriber identity module (USIM), wherein the UE has a first USIM and a second USIM; receiving a paging message from the first cell; and, in response to the paging message, sending a first response message instructing the UE to request to enter an idle or inactive mode on the first cell.

[0015] Some aspects provide a computer-readable medium for wireless communication performed by a base station (BS). The computer-readable medium includes instructions that, when executed by a processing system of a UE, cause the processing system to perform operations generally including sending a paging message requesting the user equipment (UE) to enter a connected mode on a first cell; receiving, in response to the paging message, a first response message instructing the UE to request to enter an idle or inactive mode on the first cell; and sending a reply to the first response message.

It is anticipated that elements disclosed in one aspect can be usefully used in other aspects without requiring specific description. Detailed Implementation

[0026] This disclosure provides apparatus, methods, processing systems, and computer-readable media for a UE with multiple Universal Subscription Identity Modules (i.e., multiple USIM devices) or Concurrent Radio Access Technology (C-RAT) capabilities to respond to a paging message by notifying the network that the UE has received a paging message from a cell but requests to return to an idle or inactive mode on the cell. C-RAT-capable UEs and multi-USIM UEs may not have the ability to simultaneously receive data or signaling on two access links. An important scenario is when a UE is in connected mode on a first cell associated with a first USIM, while the UE only monitors for paging messages on a second cell associated with a second USIM. If the UE is paging on the second cell but has important communications occurring on the first cell, the UE can decide to “ignore” the paging message and maintain connectivity on the first cell. In the described scenario, the UE cannot or is not preferably connected in both cells; this may be due, for example, due to resource and / or capability limitations of the UE. A simple technique for a UE to ignore a paging message is for the UE to simply not respond to the paging message. However, this would cause the network (NW) to continue paging and send paging messages in more cells, because the NW is unaware of the UE's preferences and will therefore assume that the UE simply did not receive the paging. According to various aspects of this disclosure, the UE can avoid the described problem by responding quickly to paging by notifying the NW that the UE has received the paging but requests to return to idle or inactive mode on the cell.

[0027] The following description provides examples of techniques for multiple USIM devices to respond to paging using a request to enter an idle or inactive mode on a cell that is sending a paging in a communication system, and is not intended to limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this disclosure. Various processes or components may be omitted, substituted, or added as appropriate in various examples. For example, the described methods may be performed in a different order than that described, and individual steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined in certain other examples. For example, any number of aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using structures, functions, or structures and functions other than those set forth herein or different from those set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be implemented by one or more elements of the claims. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any aspect described herein as “exemplary” is not necessarily to be construed as preferred or superior to other aspects.

[0028] Typically, 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. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, subcarrier, frequency channel, tone, subband, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, 5G NR RAT networks can be deployed.

[0029] Figure 1 An example wireless communication network 100 in which aspects of this disclosure may be implemented is shown. For example, the wireless communication network 100 may be an NR system (e.g., a 5G NR network).

[0030] like Figure 1As shown, the wireless communication network 100 may include several base stations (BSs) 110a-z (each individually referred to herein as BS 110 or collectively as BS 110) and other network entities. BS 110 may provide communication coverage for a specific geographic area, sometimes referred to as a "cell," which may be stationary or mobile depending on the location of the mobile BS 110. In some examples, BS 110 may be interconnected with each other and / or interconnected to one or more other BSs or network nodes (not shown) in the wireless communication network 100 using any suitable transport network via various types of backhaul interfaces (e.g., direct physical connection, wireless connection, virtual network, etc.). Figure 1 In the example shown, BS 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. BS 110y and 110z can be femto BSs for femto cells 102y and 102z, respectively. A BS can support one or more cells. BS 110 communicates with user equipment (UEs) 120a-y (each also individually referred to herein as UE 120 or collectively as UE 120) in the wireless communication network 100. UE 120 (e.g., 120x, 120y, etc.) can be distributed throughout the wireless communication network 100, and each UE 120 can be stationary or mobile.

[0031] Depending on certain aspects, BS 110 and UE 120 can be configured to enable multiple USIM UEs to respond to paging by requesting to enter idle or inactive mode on the paging cell. For example... Figure 1 As shown, BS 110a includes a multi-USIM UE paging manager 112. According to various aspects of this disclosure, the multi-USIM UE paging manager 112 can be configured to send a paging message requesting a user equipment (UE) to enter connected mode on a first cell; receive a first response message in response to the paging message indicating that the UE requests to enter idle or inactive mode on the first cell; and send a reply to the first response message. In some examples, the multi-USIM UE paging manager 112 may send a preamble and an indication of transmission resources for a first message in the paging message for a random access channel (RACH) procedure. Figure 1As shown, UE 120a includes a multi-USIM paging response manager 122. According to various aspects of this disclosure, the multi-USIM paging response manager 122 can be configured to reside on a first cell associated with a first universal subscriber identity module (USIM), wherein the UE has a first USIM and a second USIM; receive paging messages from the first cell; and, in response to the paging messages, send a first response message instructing the UE to request to enter an idle or inactive mode on the first cell.

[0032] The wireless communication network 100 may also include a relay station (e.g., relay station 110r) (also referred to as a relay, etc.) that receives transmissions of data and / or other information from an upstream station (e.g., BS 110a or UE 120r) and transmits such transmissions of data and / or other information to a downstream station (e.g., UE 120 or BS 110), or relays transmissions between UEs 120 to facilitate communication between devices.

[0033] Network controller 130 can be coupled to a collection of BS 110s and provide coordination and control for these BS 110s. Network controller 130 can communicate with BS 110s via backhaul. BS 110s can also communicate with each other via wireless or wired backhaul (e.g., directly or indirectly).

[0034] Figure 2 It is shown (for example, Figure 1 Example components of BS 110a and UE 120a in the wireless communication network 100, which can be used to implement various aspects of this disclosure.

[0035] At BS 110a, the transmit processor 220 can receive data from data source 212 and control information from controller / processor 240. The control information can be used for the Physical Broadcast Channel (PBCH), Physical Control Format Indicator Channel (PCFICH), Physical Hybrid ARQ Indicator Channel (PHICH), Physical Downlink Control Channel (PDCCH), Group Common PDCCH (GC PDCCH), etc. Data can be used for the Physical Downlink Shared Channel (PDSCH), etc. Processor 220 can process (e.g., encode and map symbols) the data and control information to obtain data symbols and control symbols, respectively. Transmit processor 220 can also generate reference symbols, such as those for the Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and Cell-Specific Reference Signal (CRS). Where applicable, transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, and / or reference symbols, and can provide an output symbol stream to modulators (MODs) 232a-232t. Each modulator 232 can process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signal from modulators 232a-232t can be transmitted via antennas 234a-234t respectively.

[0036] At UE 120a, antennas 252a-252r can receive downlink signals from BS 110a and can provide the received signals to demodulators (DEMODs) in transceivers 254a-254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, down-convert, and digitize) the corresponding received signal to obtain an input sample. Each demodulator can further process the input sample (e.g., for OFDM, etc.) to obtain the received symbols. MIMO detector 256 can obtain the received symbols from all demodulators 254a-254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receiver processor 258 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide data for decoding of UE 120a to data sink 260, and provide control information for decoding to controller / processor 280.

[0037] On the uplink, at UE 120a, the transmitting processor 264 can receive and process data from data source 262 (e.g., for the Physical Uplink Shared Channel (PUSCH)) and control information from controller / processor 280 (e.g., for the Physical Uplink Control Channel (PUCCH)). The transmitting processor 264 can also generate reference symbols for reference signals (e.g., for the Sounding Reference Signal (SRS)). Symbols from the transmitting processor 264 can be pre-encoded by the TX MIMO processor 266 (if applicable), further processed by demodulators in transceivers 254a-254r (e.g., for SC-FDM, etc.), and transmitted to BS 110a. At BS 110a, the uplink signal from UE 120a can be received by antenna 234, processed by modulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120a. Receiver processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240.

[0038] Memory 242 and 282 can store data and program code for BS 110a and UE 120a, respectively. Scheduler 244 can schedule the UE to transmit data on the downlink and / or uplink.

[0039] The controller / processor 280 and / or other processors and modules at UE 120a may perform or direct the execution of processes described herein. For example, as Figure 2 As shown, according to the aspects described herein, the controller / processor 240 of BS 110a has a multi-USIM UE paging manager 241, which can be configured to send a paging message requesting the user equipment (UE) to enter connected mode on a first cell; to receive a first response message in response to the paging message indicating that the UE requests to enter idle or inactive mode on the first cell; and to send a reply to the first response message. Figure 2 As shown, according to various aspects described herein, the controller / processor 280 of UE 120a has a multi-USIM paging response manager 241, which can be configured to reside on a first cell associated with a first universal subscriber identity module (USIM), wherein the UE has a first USIM and a second USIM; to receive paging messages from the first cell; and to send a first response message in response to the paging message, instructing the UE to request to enter an idle or inactive mode on the first cell. Although shown at the controller / processor, the operations described herein can be performed using other components of UE 120a and BS 110a.

[0040] UEs with C-RAT capability and multi-USIM UEs may not have the ability to receive data or signaling on two access links simultaneously. An important scenario is when a UE is in connected mode on a first cell associated with a first USIM, while the UE only monitors for paging on a second cell associated with a second USIM. If the UE is paged on the second cell but has important communication occurring on the first cell, the UE can decide to "ignore" the paging and maintain the connection on the first cell. In the described scenario, the UE cannot or is not preferably connected in both cells; this could be due, for example, due to resource and / or capability limitations of the UE. A simple technique for a UE to ignore paging is for the UE to simply not respond to the paging. However, this causes the network (NW) to continue paging and sending paging messages in more cells, as the NW is unaware of the UE's preferences and will therefore assume the UE simply did not receive the paging. According to various aspects of this disclosure, the UE can avoid the described problem by quickly responding to paging by notifying the NW that the UE has received a paging message but requests to return to idle or inactive mode on the cell.

[0041] Therefore, what is needed is a technology and apparatus for a UE with multiple Universal Subscription Identity Modules (i.e., multiple USIM devices) or Concurrent Radio Access Technology (C-RAT) capabilities to respond to a paging by notifying the network that the UE has received a paging from a cell but requests to return to an idle or inactive mode on that cell.

[0042] Example response to paging from a multi-generic subscription identity module device

[0043] This disclosure provides apparatus, methods, processing systems, and computer-readable media for a UE having multiple Universal Subscription Identity Modules (i.e., multiple USIM devices) or Concurrent Radio Access Technology (C-RAT) capabilities to respond to a paging by notifying the network that the UE has received a paging from a cell but requests to return to an idle or inactive mode on that cell.

[0044] Figure 3 This is a flowchart illustrating an example operation 300 for wireless communication according to certain aspects of this disclosure. Operation 300 can be performed, for example, by a UE (e.g., UE 120a such as in wireless communication network 100). Operation 300 can be implemented in one or more processors (e.g., Figure 2 The software components that execute and run on the controller / processor 280. Furthermore, the transmission and reception of signals performed by the UE in operation 300 can, for example, be via one or more antennas (e.g., Figure 2The antenna 252) is used to enable it. In some respects, the transmission and / or reception of signals by the UE can be achieved via a bus interface of one or more processors (e.g., controller / processor 280) that acquires and / or outputs signals.

[0045] At box 305, operation 300 can be initiated by residing on a first cell associated with a first Universal Subscriber Identity Module (USIM), wherein the UE has a first USIM and a second USIM.

[0046] At box 310, operation 300 continues to receive a paging message from the first cell.

[0047] At box 315, operation 300 continues in response to the paging message by sending a first response message instructing the UE to request to enter idle or inactive mode on the first cell.

[0048] According to various aspects of this disclosure, the UE performing operation 300 may be in idle or connected mode on a second cell associated with the second USIM.

[0049] In various aspects of this disclosure, the first response message in box 315 may be a Radio Resource Control (RRC) message.

[0050] According to various aspects of this disclosure, the first response message in block 315 may include at least one of a Radio Resource Control (RRC) Establishment Request message or an RRC Resumption Request message; and the first response message (i.e., the RRC Establishment Request message or the RRC Resumption Request message) may also include a reason value indicating that the UE requests to enter an idle or inactive mode on the first cell.

[0051] In various aspects of this disclosure, the first response message in block 315 may indicate a period of time (e.g., the length of a delay or setting the value of a timer) after which the UE will move to connected mode on the first cell in response to a paging message request.

[0052] According to various aspects of this disclosure, the UE performing operation 300 may be in an inactive mode on the first cell before receiving a paging message; and the first response message in block 315 may instruct the UE to request to enter an idle mode on the first cell.

[0053] In various aspects of this disclosure, the first response message of block 315 may include a Media Access Control (MAC) control element (CE).

[0054] According to various aspects of this disclosure, the UE performing operation 300 may send one or more second response messages instructing the UE to request to enter idle mode or inactive mode on the first cell. In some aspects of this disclosure, the UE may receive a response from the first cell and, based on that response, cease sending second response messages. In some aspects, the UE may request additional time from a second cell associated with the second USIM before receiving a response from the first cell, so as to receive the response from the first cell before resuming communication via the second cell.

[0055] In various aspects of this disclosure, the first response message in block 315 may be the first message of a Random Access Channel (RACH) procedure. That is, a UE performing operation 300 may request to enter an idle or inactive mode (in response to a receive paging message as in block 310) by sending the first message of the RACH procedure (e.g., using resources reserved by the cell for this purpose, or including a flag in the first message of the RACH procedure). In some aspects, the RACH procedure may be a four-step RACH procedure, and the UE may obtain the preamble and transmission resources for the first message of the four-step RACH procedure from the paging message in block 310. In some aspects, the RACH procedure may be a two-step RACH procedure, and the UE may obtain the preamble resources and payload resources for the first message of the two-step RACH procedure from the paging message in block 310.

[0056] According to various aspects of this disclosure, the UE performing operation 300 can avoid entering connected mode on the first cell in response to receiving a paging message in block 310.

[0057] Figure 4 This is a flowchart illustrating an example operation 400 for wireless communication according to certain aspects of this disclosure. Operation 400 can be performed, for example, by a BS (e.g., BS 110a such as in wireless communication network 100). Operation 400 can be a complementary operation performed by the BS to operation 300 performed by the UE. Operation 400 can be implemented in one or more processors (e.g., Figure 2 The software components that execute and run on the controller / processor 240. Furthermore, the transmission and reception of signals performed by the BS in operation 400 can, for example, be via one or more antennas (e.g., Figure 2 The antenna 234) is used to enable it. In some respects, the transmission and / or reception of signals by the BS can be achieved via a bus interface of one or more processors (e.g., controller / processor 240) that acquires and / or outputs signals.

[0058] At box 405, operation 400 can be initiated by sending a paging message requesting the user equipment (UE) to enter connected mode on the first cell.

[0059] At box 410, operation 400 continues in response to a paging message by receiving a first response message instructing the UE to request to enter idle or inactive mode on the first cell.

[0060] At box 415, operation 400 continues by sending a reply to the first response message.

[0061] According to various aspects of this disclosure, the first response message in block 410 may be the first message of a random access channel (RACH) procedure, and the BS performing operation 400 may send a preamble and an indication of transmission resources for the first message of the random access channel (RACH) procedure in the paging message of block 405. In some aspects, the RACH procedure may be a four-step RACH procedure. In some aspects, the RACH procedure may be a two-step RACH procedure. In some aspects, the BS may determine the indication of sending the preamble and transmission resources based on the UE having multiple Universal Subscriber Identity Modules (USIMs) or the UE supporting paging differentiation.

[0062] In various aspects of this disclosure, the first response message in block 410 may be the first message of the Random Access Channel (RACH) procedure; and the reply in block 415 may be a Random Access Response (RAR) message:

[0063] According to various aspects of this disclosure, the first response message in block 410 may be a first Radio Resource Control (RRC) message, and the BS may send a second RRC message to the UE in response to the first response message. In some aspects, the second RRC message may be an RRC release message or an RRC rejection message.

[0064] In various aspects of this disclosure, the first response message of block 410 may be a first media access control (MAC) control element (CE), and the BS may send a second MAC CE to the UE in response to the first response message.

[0065] According to various aspects of this disclosure, the first response message in block 410 may include a request from the UE to move to idle mode on the first cell, and the BS may release the inactive mode connection to the UE and move the UE to idle mode on the first cell.

[0066] In various aspects of this disclosure, the BS performing operation 400 can notify the Access Management Function (AMF) UE that it has responded to the paging message.

[0067] According to various aspects of this disclosure, the BS performing operation 400 can notify the Mobility Management Entity (MME) that the UE has responded to the paging message.

[0068] In various aspects of this disclosure, the BS performing operation 400 can notify the anchored next-generation NodeB (gNB) UE that it has responded to the paging message.

[0069] According to various aspects of this disclosure, the first response message in block 410 may indicate a time period after which the UE will respond to a paging message to request to enter connected mode on the first cell, and the BS may notify the Access Management Function (AMF) or anchor the next-generation NodeB (gNB) of that time period.

[0070] In various aspects of this disclosure, the first response message in box 410 may indicate a time period after which the UE will respond to a paging message to request to enter connected mode on the first cell, and the BS may notify the Mobility Management Entity (MME) of the time period.

[0071] Figure 5 This is an exemplary call flow 500 for UE 502, a first gNB 504 serving a first cell, and a second gNB 506 serving a second cell. According to various aspects of this disclosure, the UE is a multi-USIM UE or a UE with C-RAT capability. Similar to block 305, as described above, the call flow begins at 510 with the UE camped on the first cell. At 512, the UE begins communication with the second gNB. Communication between the UE and the second cell is ongoing and continues until at least 514. At 516, the first gNB sends a paging message to the UE. The paging message may indicate a preamble and / or transport resources for a first message used in the RACH procedure, which the UE may send to indicate a request to enter an idle or inactive mode on the first cell. At 518, the UE sends a first response message (e.g., a first message for the RACH procedure, an RRC message, or a MAC CE) to the first gNB. According to various aspects described herein, the first response message indicates a request to enter an idle or inactive mode on the first cell. Optionally, at 522, the UE sends a second response message to the first gNB.

[0076] The techniques described in this article can be used in various wireless communication technologies, such as NR (e.g., 5G NR), 3GPP Long Term Evolution (LTE), LTE-A 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. CDMA networks can implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variations of CDMA. cdma2000 covers the IS-2000, IS-95, and IS-856 standards. TDMA networks can implement radio technologies such as Global System for Mobile Communications (GSM). OFDMA networks can 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, and Flash-OFDMA. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are versions of UMTS using E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization called the 3rd Generation Partnership Project (3GPP). cdma2000 and UMB are described in documents from an organization called the 3rd Generation Partnership Project 2 (3GPP2). NR is an emerging wireless communication technology under development.

[0077] The techniques described herein can be used in the wireless networks and radio technologies mentioned above, as well as other wireless networks and radio technologies. For clarity, although this document may use terms commonly associated with 3G, 4G, and / or 5G wireless technologies to describe aspects, aspects of this disclosure can be applied to other generation-based communication systems.

[0078] 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 NR systems, the term "cell" is used interchangeably with BS, Next Generation Node B (gNB or gNodeB), Access Point (AP), Distributed Unit (DU), and Carrier or Transmit / Receive Point (TRP). A BS can provide communication coverage for macrocells, picocells, femtocells, and / or other types of cells. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UEs with a service subscription. A picocell can cover a relatively small geographic area and can allow unrestricted access by UEs with a service subscription. A femtocell can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG), UEs of users in a home). A BS used for a macrocell can be called a macro BS. A BS used for a picocell can be called a pico BS. A BS used for a femtocell can be called a femto BS or a home BS.

[0079] A UE can 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 medical equipment, biometric sensor / device, wearable device (such as 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, etc.), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media. Some UEs can be considered machine-type communication (MTC) devices or evolved MTC (eMTC) devices. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, instruments, monitors, location tags, etc., which can communicate with the BS, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network such as the Internet or cellular networks) via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices, which may be narrowband IoT (NB-IoT) devices.

[0080] 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, often referred to as tones, frequency bands, etc. Each subcarrier can be modulated with data. Typically, modulation symbols are transmitted in the frequency domain using OFDM and in the time domain using SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. For example, with a subcarrier spacing of 15 kHz, the minimum resource allocation (called a "resource block" (RB)) could be 12 subcarriers (or 180 kHz). Therefore, for system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz, the nominal Fast Fourier Transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048, respectively. System bandwidth can also be divided into subbands. For example, a subband can cover 1.08 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.

[0081] NR can utilize OFDM with CP on both uplink and downlink, and can include support for half-duplex operation using TDD. In NR, subframes are still 1ms, but the basic TTI is called a slot. Subframes contain a variable number of slots (e.g., 1, 2, 4, 8, 16... slots) depending on the subcarrier spacing. NR RBs are 12 consecutive frequency subcarriers. NR can support a basic subcarrier spacing of 15kHz, and other subcarrier spacings can be defined relative to the basic subcarrier spacing, such as 30kHz, 60kHz, 120kHz, 240kHz, etc. Symbol and slot lengths are proportional to the subcarrier spacing. The CP length also depends on the subcarrier spacing. Beamforming can be supported, and beam direction can be dynamically configured. MIMO transmission with precoding can also be supported. In some examples, MIMO configurations in DL can support up to 8 transmit antennas, with up to 8 streams in multilayer DL transmission and up to 2 streams per UE. In some examples, multilayer transmission with up to 2 streams per UE can be supported. It can support aggregation of multiple cells with up to 8 service cells.

[0082] In some examples, access to the air interface can 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 can be responsible for scheduling, dispatching, reconfiguring, and releasing resources for one or more subordinate entities. That is, for 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 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 peer-to-peer (P2P) networks and / or mesh networks. In mesh network examples, UEs can communicate directly with each other in addition to communicating with a scheduling entity.

[0083] In some examples, two or more dependent entities (e.g., UEs) can use sidelink signaling to communicate with each other. Real-world applications of such sidelink communication can include public safety, proximity services, UE-to-network relay, vehicle-to-vehicle (V2V) communication, Internet of Things (IoE) communication, IoT communication, mission-critical meshes, and / or various other suitable applications. Typically, sidelink signaling can refer to a signal that is transmitted from one dependent entity (e.g., UE1) to another dependent entity (e.g., UE2) without relaying the communication through a scheduling entity (e.g., UE or BS), even if the scheduling entity may be used for scheduling and / or control purposes. In some examples, licensed spectrum can be used to transmit sidelink signals (unlike wireless LANs that typically use unlicensed spectrum).

[0088] The various operations described above can be performed by any suitable component capable of performing the corresponding function. These components may include various hardware and / or software components and / or modules, including but not limited to circuits, application-specific integrated circuits (ASICs), or processors. Typically, where the operations shown in the accompanying drawings are present, those operations may have corresponding paired components plus functional components with similar reference numerals.

[0089] The various illustrative logic blocks, modules, and circuits described herein can be implemented or executed using a general-purpose processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), 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. The general-purpose processor may be a microprocessor, but alternatively, 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, such as a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors combined with a DSP core, or any other such configuration.

[0090] If implemented in hardware, an example hardware configuration could include a processing system within a wireless node. This processing system can be implemented using a bus architecture. The bus can include any number of interconnect buses and bridges, depending on the specific application and overall design constraints of the processing system. The bus can link various circuits together, including processors, machine-readable media, and bus interfaces. The bus interface can be used to connect network adapters and others to the processing system via the bus. The network adapter can be used to implement signal processing functions at the PHY layer. In user terminal 120 (see...) Figure 1 In this case, the user interface (e.g., buttons, display, mouse, joystick, etc.) can also be connected to the bus. The bus can also link various other circuits, such as timing sources, peripherals, voltage regulators, power management circuits, etc., which are well known in the art and will not be described further. The processor can be implemented using one or more general-purpose and / or special-purpose processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuits capable of executing software. Those skilled in the art will recognize that how best to implement the described functions for the processing system depends on the specific application and the overall design constraints imposed on the system as a whole.

[0091] If implemented in software, the functionality can be stored on or transmitted via a computer-readable medium as one or more instructions or code. Software should be broadly interpreted as 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, with communication media including any medium that facilitates the transfer of a computer program from one location to another. The processor may be responsible for managing the bus and general processing, including the execution of software modules stored on the machine-readable storage medium. The computer-readable storage medium may be coupled to the processor so that the processor can read information from and write information to the storage medium. Alternatively, the storage medium may be integrated into the processor. For example, the machine-readable medium may include a transmission line, a carrier wave modulated by data, and / or a separate computer-readable storage medium with instructions stored thereon, all accessible to the processor via a bus interface. Alternatively, or additionally, the machine-readable medium or any portion thereof may be integrated into the processor, such as in cases potentially relating to caches and / or general-purpose register files. Examples of machine-readable storage media may include, for example, 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, disks, optical disks, hard disks, or any other suitable storage media or any combination thereof. Machine-readable media may be implemented as computer program products.

[0092] Software modules can comprise a single instruction or a number of instructions, and can be distributed across multiple different code segments, different programs, and across multiple storage media. Computer-readable media can include multiple software modules. A software module includes instructions that, when executed by a device such as a processor, cause the processing system to perform various functions. Software modules can include sending modules and receiving modules. Each software module can reside in a single storage device or can be distributed across multiple storage devices. For example, a software module can be loaded from a hard disk drive into RAM when a trigger event occurs. During the execution of a software module, the processor can load some of the instructions into a cache to improve access speed. One or more cache lines can then be loaded into a general-purpose register file for execution by the processor. When referring to the functionality of a software module below, it should be understood that such functionality is implemented by the processor when executing instructions from that software module.

[0093] Furthermore, any connection can be appropriately referred to as computer-readable medium. For example, the definition of medium includes coaxial cable, optical fiber, twisted pair, DSL, or wireless technologies (such as infrared (IR), radio, and microwave) when transmitting software from a website, server, or other remote source. As used herein, discs and disks include compact discs (CDs), laser discs, optical discs, digital versatile discs (DVDs), floppy disks, and... Disks, where magnetic disks typically reproduce data magnetically, and optical disks reproduce data optically using lasers. Therefore, in some aspects, computer-readable media may include non-transitory computer-readable media (e.g., tangible media). Furthermore, in other aspects, computer-readable media may include transient computer-readable media (e.g., signals). Combinations of the foregoing should also be included within the scope of computer-readable media.

[0094] Therefore, certain aspects may include a computer program product for performing the operations presented herein.
