LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile services standard promulgated by the Third Generation Partnership Project (3GPP).

A wireless network may include one or more base stations that support communication for a user equipment (UE) or multiple UEs. The UE can communicate with the base station via downlink communication and uplink communication.

Although aspects may be described using terms commonly associated with 5G or New Radio (NR) Radio Access Technologies (RATs), aspects of the present disclosure may apply to other RATs, such as 3G RATs, 4G RATs, and/or Or RATs after 5G (e.g., 6G).

1 is a diagram illustrating an example of a wireless network 100 in accordance with the present disclosure. The wireless network 100 can be or include elements of a 5G (eg, NR) network and/or a 4G (eg, Long Term Evolution (LTE)) network, among others. Wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d), user equipment (UE) 120, or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e) and/or other network entities. Base station 110 is an entity that communicates with UE 120 . Base stations 110 (sometimes referred to as BSs) may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, and/or transmission Receive Point (TRP). Each base station 110 can provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), the term "cell" can refer to a coverage area of a base station 110 and/or a base station subsystem serving the coverage area, depending on the context in which the term is used.

The base station 110 may provide communication coverage for macrocells, picocells, femtocells, and/or another type of cell. A macrocell may cover a relatively large geographic area (eg, several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscriptions. A picocell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with a service subscription. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow limited presence of UEs 120 associated with the femtocell (e.g., UEs 120 in a Closed Subscriber Group (CSG)). Pick. The base station 110 for macro cells may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femtocell may be referred to as a femto base station or a home base station. In the example shown in FIG. 1, BS 110a may be a macro base station for macrocell 102a; BS 110b may be a pico base station for picocell 102b; and BS 110c may be a picocell for femtocell 102c. femto base station. A base station can support one or more (eg, three) cells.

In some instances, a cell may not necessarily be stationary, and the geographic area of the cell may move depending on the location of the mobile base station 110 (eg, mobile base station). In some examples, base stations 110 may be interconnected to each other and/or to one or more of wireless networks 100 via various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network. other base stations 110 or network nodes (not shown).

Wireless network 100 may include one or more relay stations. A relay station is an entity that may receive data transmissions from upstream stations (eg, base station 110 or UE 120 ) and send data transmissions to downstream stations (eg, UE 120 or base station 110 ). A relay station may be a UE 120 that can relay transmissions for other UEs. In the example shown in FIG. 1, BS 110d (eg, a relay base station) may communicate with BS 110a (eg, a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. The base station 110 that relays communications may be called a relay station, a relay base station, a repeater, and the like.

The wireless network 100 may be a heterogeneous network including different types of base stations 110, such as macro base stations, pico base stations, femto base stations, relay base stations, and so on. The different types of base stations 110 may have different transmit power levels, different coverage areas, and/or different effects on interference in the wireless network 100 . For example, macro base stations may have higher transmit power levels (e.g., 5 to 40 watts), while pico, femto, and relay base stations may have lower transmit power levels (e.g., 0.1 to 2 watts).

A network controller 130 may be coupled to or communicate with a group of base stations 110 and provide coordination and control for the base stations 110 . The network controller 130 can communicate with the base station 110 via the backhaul communication link. The base stations 110 can communicate with each other directly or indirectly via wireless or wired backhaul communication links.

UEs 120 may be dispersed throughout wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, terminal, mobile station, and/or subscriber unit. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop, a wireless phone, a wireless local loop (WLL) station, a tablet Computers, cameras, gaming devices, netbooks, smart computers, ultrabooks, medical devices, biometric devices, wearable devices (e.g., smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings or smart bracelets), entertainment devices (e.g., music devices, video devices, and/or satellite radios), vehicle components or sensors, smart meters/sensors, industrial manufacturing equipment, GPS devices, and/or Any other suitable device configured to communicate via a wireless medium.

Some UEs 120 may be considered machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and/or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and /location tab. Some UEs 120 may be considered Internet of Things (IoT) devices, and/or may be implemented as NB-IoT (Narrow Band IoT) devices. Some UEs 120 may be considered customer premise equipment. The UE 120 may be included inside a housing housing components of the UE 120 such as processor components and/or memory components. In some instances, a processor component and a memory component may be coupled together. For example, processor components (eg, one or more processors) and memory components (eg, memories) may be operably, communicatively, electronically, and/or electrically coupled.

In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as a relay) using one or more sidelink channels to communicate with each other communication). For example, UE 120 may use peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (which may include, for example, vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol or vehicle-to-pedestrian (V2P) protocol) and/or mesh networks for communication. In such instances, UE 120 may perform the scheduling operations performed by base station 110, resource selection operations, and/or other operations described elsewhere herein.

Devices in the wireless network 100 can use electromagnetic spectrum for communication, and the electromagnetic spectrum can be subdivided into various categories, frequency bands, channels, etc. according to frequency or wavelength. For example, devices of the wireless network 100 may communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been identified as frequency range designations FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and articles, despite the portion of FR1 that is greater than 6 GHz. A similar nomenclature issue sometimes arises for FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it differs from what is identified as "millimeter wave" by the International Telecommunication Union (ITU) The extremely high frequency (EHF) band (30 GHz–300 GHz) of the frequency band.

The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified the operating band for such mid-band frequencies as the frequency range designation FR3 (7.125 GHz-24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend the characteristics of FR1 and/or FR2 to 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 frequency bands have been identified as frequency range designations 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 belongs to the EHF band.

With the above examples in mind, and unless expressly stated otherwise, it should be understood that when used herein, the term "below 6 GHz", etc. can be used broadly to mean that it may be less than 6 GHz, may be within FR1, or may include mid-band frequencies Frequency of. In addition, unless expressly stated otherwise, it should be understood that the terms "millimeter wave" and the like, if used herein, can be broadly denoted to include mid-band frequencies, and/or frequencies within FR5 or possibly within the EHF band. It is contemplated that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified and that the techniques described herein apply to those modified frequencies scope.

In some aspects, UE 120 may include communication manager 140 . As described in more detail elsewhere herein, the communication manager 140 may perform one or more operations associated with downlink feedback information (DFI) with physical downlink control channel (PDCCH) repetition. Additionally or alternatively, communications manager 140 may perform one or more other operations described herein.

Although the resource structure 300 is shown as including 2 slots per subframe, a different number of slots may be included in a subframe (e.g., 4 slots, 8 slots, 16 slots, 32 slots, etc.) slot or another number of time slots). In some aspects, a different type of transmission time interval (TTI) may be used instead of subframes and/or slots. A time slot 310 may include a number of symbols 315, such as 7 symbols per time slot.

The underlying control region of slot 310 may be referred to as a control resource set (CORESET) 320, and may be configured to support efficient use of resources, such as by linking resources used for one or more PDCCHs and/or one or more entity downlink The resources of the CORESET 320 of the Link Shared Channel (PDSCH) can be flexibly configured or reconfigured. In some aspects, CORESET 320 may occupy the first symbol 315 of time slot 310 , the first two symbols 315 of time slot 310 , or the first three symbols 315 of time slot 310 . Thus, a CORESET 320 may include multiple resource blocks (RBs) in the frequency domain, and one, two or three symbols 315 in the time domain. In 5G, the number of resources included in CORESET 320 can be flexibly configured, such as by using radio resource control (RRC) signaling to indicate the frequency domain region (e.g., number of resource blocks) and/or timing for CORESET 320 Domain area (for example, number of symbols).

As shown, a symbol 315 including a CORESET 320 may include one or more control channel elements (CCEs) 325, shown as two CCEs 325 as an example, spanning a portion of the system bandwidth. CCE 325 may include downlink control information (DCI) for providing control information for wireless communications. A base station may transmit DCI during multiple CCEs 325 (as shown), where the number of CCEs 325 used to transmit DCI indicates the aggregation level (AL) that the base station uses to transmit DCI. In FIG. 3 , an aggregation level of 2 corresponding to two CCEs 325 in a time slot 310 is illustrated as an example. In some aspects, different aggregation levels may be used, such as 1, 2, 4, 8, 16, or another aggregation level.

Each CCE 325 may include a fixed number of resource element groups (REGs) 330 , shown as six REGs 330 , or may include a variable number of REGs 330 . In some aspects, the number of REGs 330 included in a CCE 325 may be specified by a REG bundle size. REG 330 may include one resource block, which may include 12 resource elements (REs) 335 within symbol 315 . A resource element 335 may occupy one subcarrier in the frequency domain and one OFDM symbol in the time domain.

The search space may include all possible locations (eg, in time and/or frequency) where the PDCCH may be located. CORESET 320 may include one or more search spaces, such as a UE-specific search space, a group common search space, and/or a common search space. A search space may indicate a set of CCE locations where a UE may find a PDCCH that may potentially be used to send control information to the UE. The possible location of the PDCCH may depend on whether the PDCCH is a UE-specific PDCCH (eg, for a single UE) or a group-common PDCCH (eg, for multiple UEs) and/or the aggregation level being used. Possible locations (eg, in time and/or frequency) of a PDCCH may be referred to as PDCCH candidates, and the set of all possible PDCCH locations at an aggregation level may be referred to as a search space. For example, the set of all possible PDCCH positions for a particular UE may be referred to as a UE-specific search space. Similarly, the set of all possible PDCCH positions across all UEs may be referred to as a common search space. The set of all possible PDCCH positions for a particular group of UEs may be referred to as a group common search space. One or more search spaces across aggregation levels may be referred to as a search space (SS) set.

In some cases, a UE may receive DCI via a PDCCH candidate. In some cases, DCI may include DFI indicating feedback information associated with one or more previous PUSCH transmissions. For example, DCI may include a specific format (eg, DCI format 0_1 ) where a cyclic redundancy check (CRC) is scrambled by a configured scheduled radio network temporary identifier (CS-RNTI). DCI may include a DFI flag field. The UE may decide that the DCI includes DFI when the DFI flag field is set to a first value (eg, 1), and may decide that the DCI does not include DFI when the DFI flag field is set to a second value (eg, 0).

When the DFI flag field is set to the first value, the DFI included in the DCI may include a 16-bit bitmap indicating each identifier for the previous PUSCH transmission (e.g., for each HARQ identifier) feedback information (eg, hybrid automatic repeat request (HARQ) feedback information). In some cases, the UE may determine the validity of the DFI for each PUSCH transmission based at least in part on when the PUSCH transmission is received for the first symbol of the DCI that includes the DFI (e.g., the DCI is sent by the base station 110 to the UE) .

In some cases, PUSCH transmissions may not be sent repeatedly. PUSCH transmissions may be associated with a semi-static configuration (eg, configured by the allowance of the configuration) or may be dynamically scheduled. The UE may decide that the DFI is valid for each PUSCH transmission having the last symbol sent at least a certain number of symbols before the first symbol of DCI received by the UE. In some cases, the specific number of symbols may be configured by the network (eg, base station 110 sends DCI to UE). For example, as shown in FIG. 3B , a certain number of symbols may correspond to a configured allowable minimum DFI delay (cg-minDFI-Delay) parameter 340 .

The UE may decide, at least in part, that the DFI is for PUSCH transmissions associated with HARQ identifiers 3 and 4 are invalid. The UE may decide based at least in part on the fact that the last symbol of each PUSCH transmission was sent at least the number of symbols indicated by the cg-minDFI-Delay parameter 340 before the first symbol of the DCI including the DFI received by the UE DFI is valid for PUSCH transmissions associated with HARQ identifiers 0, 1 and 8.

In some cases, as shown in Figure 3C, a PUSCH transmission (eg, a PUSCH transmission associated with HARQ identifier 1, as shown) may be configured with configured allowances and may be sent repeatedly. In such cases, a UE may decide that a DFI is valid for a PUSCH transmission when the last symbol of any repetition of the PUSCH transmission is sent at least a specified number of symbols before the first symbol of the DCI carrying the DFI received by the UE .

In some cases, as shown in FIG. 3D , PUSCH transmissions (eg, PUSCH transmissions associated with HARQ identifier 1, as shown) may be scheduled by dynamic grants and may be sent repeatedly. In such cases, when the DFI indicates an acknowledgment (ACK) associated with the PUSCH transmission, and the last symbol of the first repetition of the PUSCH transmission is at least specified before the first symbol of the DCI carrying the DFI received by the UE The UE may decide that DFI is valid for PUSCH transmission when transmitted at the number of symbols.

In some cases, DFI may indicate a negative acknowledgment (NACK) associated with a PUSCH transmission. In such cases, the UE may decide that the DFI is valid for the PUSCH transmission when the last symbol of the last repetition of the PUSCH transmission is sent at least a certain number of symbols before the first symbol of the DCI carrying the DFI received by the UE . As shown in FIG. 3E , the UE may base, at least in part, the last symbol of the last repetition of the PUSCH transmission (e.g., repetition 4, as shown) not being at least For a certain number of symbols, DFI is determined to be invalid for PUSCH transmissions associated with HARQ identifier (ID) 1.

In some cases, each PDCCH candidate may be repeatedly configured. For example, two SS sets can be concatenated by RRC configuration. The PDCCH candidates of two concatenated SS sets may be mapped one-to-one (eg, the first PDCCH candidate of the first SS set may be mapped to the first PDCCH candidate of the second SS set). Two PDCCH candidates mapped together may have the same aggregation level and may carry the same DCI payload.

The UE may receive two PDCCH candidates and may decode the DCI in either the first PDCCH candidate received by the UE or the second PDCCH candidate received by the UE, or may perform soft combining to decode the DCI. Therefore, the UE may check the DCI included in the first PDCCH candidate received by the UE, the DCI included in the second PDCCH candidate received by the UE, or the DCI included in the first PDCCH candidate received by the UE and the first PDCCH candidate received by the UE. Both DCIs included in the two PDCCH candidates are decoded.

In some cases, DCI may include DFI indicating feedback information associated with one or more previous PUSCH transmissions. For example, DCI may include a specific format (eg, DCI format 0_1 ) where CRC is scrambled by CS-RNTI. The DCI may include a DFI flag field set to a first value (eg, 1) indicating that the DCI includes the DFI associated with the previous PUSCH transmission. The UE may decide whether DFI is valid for PUSCH transmission in a manner similar to that described above. However, since the UE may decode DCI included in the first PDCCH candidate, the second PDCCH candidate, or both the first and second PDCCH candidates, the first symbol of DCI carrying DFI may be based at least in part on the The DCI decoded by the UE is different. Accordingly, the UE may decide different outcomes as to whether DFI is valid for PUSCH transmission based at least in part on the DCI decoded by the UE.

Some techniques and apparatus described herein enable a UE to recognize references that will be used to decide whether DFI is valid for PUSCH transmission when the UE receives concatenated PDCCH candidates. In some aspects, a UE may determine a reference to correspond to DCI received via a PDCCH candidate that satisfies one or more criteria. By using a reference to decide whether the DFI included in the DCI is valid for PUSCH transmission, the UE can prevent different outcomes based at least in part on the DCI decoded by the UE.

As indicated above, Figures 3A-3E are provided as examples. Other examples may differ from the examples described with respect to FIGS. 3A-3E .

4A-4D are diagrams illustrating examples 400, 415, 430, 445 associated with DFI with PDCCH repetition in accordance with the present disclosure. As shown in FIG. 4A , in some aspects, a UE (eg, UE 120 ) may receive a set of PDCCH candidates (eg, PDCCH candidate 405 and PDCCH candidate 410 , as shown). As described elsewhere herein, PDCCH candidates may be concatenated for PDCCH repetition.

In some aspects, the UE may detect DCI carrying DFI in one or more of the PDCCH candidates 405 , 410 . In some aspects, the UE may decode the PDCCH candidate 405 and may detect that the DCI includes the DFI. In some aspects, the UE may decode the PDCCH candidates 410 and may detect that the DCI includes the DFI. In some aspects, the UE may perform soft combining to decode PDCCH candidates 405 and PDCCH candidates 410 and may detect DCI including DFI based at least in part on performing soft combining to decode PDCCH candidates 405 and PDCCH candidates 410 .

In some aspects, the UE may detect that the DCI carries DFI based at least in part on the fact that the DCI includes a specific format (eg, DCI format 0_1) with a CRC scrambled by the CS-RNTI set to a specific DFI flag field with a value (for example, 1). The DFI may include a 16-bit bitmap indicating feedback information (eg, HARQ feedback information) for each identifier (eg, each HARQ identifier) of previous PUSCH transmissions.

In some aspects, the UE may determine one or more reference criteria for determining the reference to be used in determining the validity of DFI for each PUSCH transmission. In some aspects, one or more reference criteria may indicate that a PDCCH candidate that starts earliest in time relative to other PDCCH candidates is to be selected as a reference and a PDCCH candidate that ends earliest in time relative to other PDCCH candidates is to be selected As a reference, the PDCCH candidate that starts latest with respect to other PDCCH candidates will be selected as a reference, or the PDCCH candidate that ends latest in time with respect to other PDCCH candidates will be selected as a reference, and so on.

In some aspects, the UE may determine that the PDCCH candidate 405 satisfies one or more reference criteria and may select the PDCCH candidate 405 as a reference. In some aspects, the UE may determine that PDCCH candidate 410 satisfies one or more reference criteria and may select PDCCH candidate 410 as a reference.

In some aspects, as shown in Figure 4A, previous PUSCH transmissions may not be sent repeatedly. The UE may determine the validity of the DFI for the previous PUSCH transmission based at least in part on whether the previous PUSCH transmission was sent without repetition. For example, the UE may decide on a PUSCH transmission for a previous PUSCH transmission based at least in part on whether the last symbol of the previous PUSCH transmission was sent at least a certain number of symbols before the referenced first symbol in a manner similar to that described elsewhere herein. Validity of DFIs. As shown in FIG. 4A , the UE may determine the DFI for HARQ IDs associated with HARQ IDs 8, 0, and 1 based at least in part on the fact that the last symbol of the previous PUSCH transmission was sent at least a specified number of symbols before the referenced first symbol. The previous PUSCH transmission was valid. As also shown in FIG. 4A , the UE may determine the DFI for a previous PUSCH transmission associated with HARQ ID 3 based at least in part on the fact that the last symbol of the previous PUSCH transmission was not sent at least a specified number of symbols before the referenced first symbol. invalid.

In some aspects, previous PUSCH transmissions may be configured with configured allowances and may be sent repeatedly, as shown in FIG. 4B . The UE may determine the validity of the DFI for the previous PUSCH transmission based at least in part on the configured allowance of the previous PUSCH transmission and at least in part on the previous PUSCH transmission being repeatedly sent. For example, the UE may decide to target a previous PUSCH transmission based at least in part on whether the last symbol of any repetition of a previous PUSCH transmission was sent at least a specified number of symbols before the referenced first symbol, in a manner similar to that described elsewhere herein. Validity of DFI for PUSCH transmission. As shown in FIG. 4B, the UE may decide that the DFI is valid for the previous PUSCH transmission based at least in part on the fact that the last symbol of at least the first repetition of the previous PUSCH transmission was sent at least a specified number of symbols before the referenced first symbol .

In some aspects, as shown in Figure 4C, previous PUSCH transmissions may be scheduled by dynamic grants and may be sent repeatedly. In some aspects, as also shown in Figure 4C, DFI may indicate ACK. The UE may determine the validity of the DFI for the previous PUSCH transmission based at least in part on the dynamic allowable scheduling of the previous PUSCH transmission and based at least in part on the DFI indicating ACK. For example, the UE may decide based at least in part on whether the last symbol of the first repetition of the previous PUSCH transmission was sent at least a certain number of symbols before the referenced first symbol, in a manner similar to that described elsewhere herein. Validity of DFI for previous PUSCH transmissions. As shown in FIG. 4C , the UE may determine that DFI is valid for the previous PUSCH transmission based at least in part on the fact that the last symbol of the first repetition of the previous PUSCH transmission was sent at least a specified number of symbols before the referenced first symbol.

In some aspects, DFI may indicate a NACK, as shown in Figure 4D. The UE may determine the validity of the DFI for the previous PUSCH transmission based at least in part on the previous PUSCH transmission being dynamically allowed to schedule and based at least in part on the DFI indicating NACK. For example, the UE may decide, in a manner similar to that described elsewhere herein, based at least in part on whether the last symbol of the last repetition of a previous PUSCH transmission was sent at least a certain number of symbols before the referenced first symbol. Validity of DFI for previous PUSCH transmissions. As shown in FIG. 4D , the UE may decide that DFI is not valid for the previous PUSCH transmission based at least in part on the fact that the last symbol of the last repetition of the previous PUSCH transmission was not sent at least a specified number of symbols before the referenced first symbol.

The feedback information for the transport block corresponding to the HARQ process number is valid for PUSCH transmission (block 540). For example, the mobile station (e.g., using the communication manager 140 and/or the decision component 612 depicted in FIG. 6 ) may be based at least in part on whether the last symbol of the PUSCH transmission precedes the first symbol of the reference PDCCH candidate by at least some amount to determine whether the feedback information in the DFI for the transport block corresponding to the HARQ process number is valid for PUSCH transmission, as described above.
