Description

Technical Field

[0001] Embodiments of the present disclosure relate generally to wireless communication techniques, and more particularly to methods and apparatus for uplink (UL) transmission in a full-duplex (FD) system. Background Art

[0002] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasts, etc. Wireless communication systems may employ a variety of access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of wireless communication systems may include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, Advanced LTE (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may also be referred to as New Radio (NR) systems.

[0003] In wireless communication systems, the term "duplex" may refer to bidirectional communication between two devices, where "full-duplex" means that transmissions over a link in each direction occur simultaneously, and "half-duplex" means that transmissions over a link in each direction occur at mutually exclusive times. Details regarding UL transmissions in a full-duplex system need to be studied. Summary of the invention

[0051] The detailed description of the accompanying drawings is intended as a description of the preferred embodiments of the present disclosure and is not intended to represent the only form in which the present disclosure can be practiced. It should be understood that the same or equivalent functions can be achieved by different embodiments, which are intended to be included in the spirit and scope of the present disclosure.

[0052] Reference will now be made in detail to some embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. To facilitate understanding, the embodiments are provided under a specific network architecture and a new service scenario (e.g., 3rd Generation Partnership Project (3GPP) 5G (NR), 3GPP Long Term Evolution (LTE) Release 8, etc.). Please consider that, with the development of network architecture and new service scenarios, all embodiments in the present disclosure are also applicable to similar technical problems; and in addition, the terms stated in the present disclosure may be changed, which should not affect the principles of the present disclosure.

[0053] Figure 1 A schematic diagram of a wireless communication system 100 is illustrated in accordance with some embodiments of the present disclosure.

[0054] like Figure 1 As shown in FIG. 1 , a wireless communication system 100 may include some UEs 101 (e.g., UE 101a and UE 101b) and a base station (e.g., BS 102). Figure 1 A specific number of UEs 101 and BSs 102 are depicted in FIG. 1 , but please consider that any number of UEs and BSs may be included in the wireless communication system 100 .

[0055] UE 101 may include a computing device, such as a desktop computer, a laptop computer, a personal digital assistant (PDA), a tablet computer, a smart TV (e.g., a TV connected to the Internet), a set-top box, a game console, a security system (including a security camera), a car computer, a network device (e.g., a router, a switch and a modem), etc. According to some embodiments of the present disclosure, UE 101 may include a portable wireless communication device, a smart phone, a cellular phone, a flip phone, a device with a subscriber identity module, a personal computer, a selective call receiver, or any other device capable of sending and receiving communication signals on a wireless network. In some embodiments of the present disclosure, UE 101 includes a wearable device, such as a smart watch, a fitness band, an optical head-mounted display, etc. In addition, UE 101 may be referred to as a subscriber unit, a mobile device, a mobile station, a user, a terminal, a mobile terminal, a wireless terminal, a fixed terminal, a subscriber station, a user terminal or a device, or described using other terms used in the art. UE 101 may communicate with BS 102 via an uplink (UL) communication signal.

[0056] BS 102 may be distributed over a geographic area. In certain embodiments of the present disclosure, BS 102 may also be referred to as an access point, access terminal, base, base unit, macro cell, Node B, evolved Node B (eNB), gNB, Home Node B, relay node or device, or described using other terms used in the art. BS 102 is typically part of a radio access network, which may include one or more controllers communicatively coupled to one or more corresponding BS 102. BS 102 may communicate with UE 101 via downlink (DL) communication signals.

[0057] The wireless communication system 100 may be compatible with any type of network capable of sending and receiving wireless communication signals. For example, the wireless communication system 100 is compatible with a wireless communication network, a cellular telephone network, a network based on time division multiple access (TDMA), a network based on code division multiple access (CDMA), a network based on orthogonal frequency division multiple access (OFDMA), an LTE network, a network based on 3GPP, a 3GPP 5G network, a satellite communication network, a high altitude platform network, and / or other communication networks.

[0058] In some embodiments of the present disclosure, the wireless communication system 100 is compatible with 5G NR of the 3GPP protocol. For example, the BS 102 may transmit data on the DL using an orthogonal frequency division multiplexing (OFDM) modulation scheme and the UE 101 may transmit data on the UL using a discrete Fourier transform-spread spectrum-orthogonal frequency division multiplexing (DFT-S-OFDM) or cyclic prefix-OFDM (CP-OFDM) scheme. However, more generally, the wireless communication system 100 may implement some other open or proprietary communication protocols, such as WiMAX and other protocols.

[0059] In some embodiments of the present disclosure, BS 102 and UE 101 may communicate using other communication protocols such as wireless communication protocols of the IEEE 802.11 family. In addition, in some embodiments of the present disclosure, BS 102 and UE 101 may communicate via a licensed spectrum, while in some other embodiments, BS 102 and UE 101 may communicate via an unlicensed spectrum. The present disclosure is not intended to be limited to implementations of any particular wireless communication system architecture or protocol.

[0060] In wireless communication systems, the term "duplex" may mean bidirectional communication between two devices, where "full-duplex" means transmissions over the link in each direction occur simultaneously and "half-duplex" means transmissions over the link in each direction occur at mutually exclusive times.

[0061] Figure 2 Illustrated are exemplary duplex modes according to some embodiments of the present disclosure.

[0062] refer to Figure 2 , the duplex mode may include, for example, a full-duplex frequency division duplex (FD-FDD) mode, a TDD mode, and a half-duplex frequency division duplex (HD-FDD) mode.

[0063] In some examples, in a full-duplex transceiver, different carrier frequencies (e.g., carrier A and carrier B) may be used for transmission in each link direction, e.g., carrier A may be used for uplink transmissions and carrier B may be used for downlink transmissions. This type of full-duplex may be referred to as FD-FDD mode.

[0064] In a half-duplex (HD) transceiver, transmissions in each link direction may be separated by time domain resources. In some cases, the same carrier frequency is used for transmissions in each link direction, such as carrier A is used for both uplink and downlink transmissions, and this type of half-duplex may be referred to as TDD mode. In some other cases, different carrier frequencies may be used for transmissions in each link direction, such as carrier A may be used for uplink transmissions and carrier B may be used for downlink transmissions, and this type of half-duplex may be referred to as HD-FDD mode.

[0065] The embodiments of the present disclosure are Figure 2 The FD-FDD mode illustrated in the figure provides improvements. For example, an advanced full-duplex mode is provided, which enables simultaneous transmission and reception on the same carrier by the same device. The advanced full-duplex mode is advantageous. For example, the advanced full-duplex mode can improve link throughput. In addition, due to simultaneous bidirectional transmission, the transmission latency in the advanced full-duplex mode can also be reduced. Depending on whether overlapping DL and UL resource occupancy is allowed in the advanced full-duplex mode, the advanced full-duplex mode can be divided into several types.

[0066] Figure 3 Illustrated are exemplary types of advanced full-duplex modes according to some embodiments of the present disclosure.

[0067] refer to Figure 3 , exemplary types of advanced full-duplex modes may include advanced FD mode #1 and advanced FD mode #2. In advanced FD mode #1, UL transmission and DL transmission occupy different frequency resources in the same carrier (e.g., carrier A), while in advanced FD mode #2, UL transmission and DL transmission occupy overlapping resources in the same carrier (e.g., carrier A).

[0068] Simultaneous DL transmission and UL transmission in the same carrier may cause self-interference. For example, in the BS side, DL transmission may pollute UL reception, while in the UE side, UL transmission may pollute DL reception. Due to non-overlapping DL and UL resources, this self-interference level in Advanced FD Mode #1 will be much lower than that in Advanced FD Mode #2.

[0069] It is more feasible to implement full duplex in the BS side than in the UE side for the following reasons. First, more space is available in the BS side so that the transmitter (Tx) and receiver (Rx) antenna branches can be separated to achieve self-interference cancellation. In addition, more complex and advanced transceivers can be used in the BS side, which may be essential for self-interference cancellation.

[0070] In view of the above, one scenario for implementing full-duplex mode is to deploy only in the BS side such as Figure 3 , while still deploying half-duplex mode in the UE side. In this scenario, in a time unit (e.g., time slot) with full-duplex mode, the BS can perform UL reception from some UEs while performing DL transmission to some other UEs in non-overlapping frequency resources within the time unit.

[0071] The above scenario can be used in a TDD system to improve UL performance in the TDD system. For example, with full duplex in the BS side, UL subbands can be configured in some DL time slots so that UL transmission can be extended into such subbands in the DL time slots.

[0072] Figure 4 Illustrated are exemplary radio resources in a TDD system according to some embodiments of the present disclosure.

[0073] In some examples, in a TDD system, DL transmission and UL transmission may be separated by time domain resources (eg, time slots). For example, DL transmission may be performed in DL time slots #n to #n+2 (eg, Figure 4 ), and UL transmission can be performed in UL time slots #n+3 to #n+4 (as shown in Figure 4 ).

[0074] The full-duplex mode in the BS side can be introduced into the TDD system. For example, for a UE supporting the full-duplex mode in the BS side, in addition to scheduling UL transmission in the active UL bandwidth part (BWP) in the UL time slot, UL transmission can also be scheduled in a subband in the DL time slot in the TDD system. Figure 4 As shown in , UL transmission may occur in subbands in DL slots #n+1 and #n+2. In other words, slots #n+1 and #n+2 are configured with UL subbands.

[0075] The above embodiments illustrate that better UL coverage, lower UL transmission latency, and improved UL capabilities can be achieved. In some embodiments of the present disclosure, UL transmissions (e.g., PUCCH transmissions, PUSCH transmissions, or any combination thereof) may be performed in configured subbands in one or more DL time slots. Embodiments of the present disclosure provide solutions for determining resources for PUCCH transmissions and PUSCH transmissions in a subband. For example, embodiments of the present disclosure propose solutions for UL transmissions in a full-duplex (FD) system (e.g., deploying advanced FD mode #1 in the BS side and deploying half-duplex mode in the UE side), which can determine resources for PUCCH transmissions and / or PUSCH transmissions in a subband.

[0076] In addition, the solution in the embodiments of the present disclosure can also reduce the signaling overhead for determining the resources for PUCCH transmission and / or PUSCH transmission in the subband and facilitate UL reception, thereby achieving better UL coverage, lower UL transmission latency and improved UL capability. More details about the embodiments of the present disclosure will be illustrated below in conjunction with the accompanying drawings.

[0077] In order to reduce the signaling overhead for determining resources for PUCCH transmission and / or PUSCH transmission in a subband and facilitate UL reception, if specific conditions are met, embodiments of the present disclosure may reuse PUCCH resources and / or PUSCH resources configured for the BWP for PUCCH transmission and / or PUSCH transmission in a subband.

[0078] Figure 5 Illustrated is a method for determining resources for PUCCH transmission and / or PUSCH transmission for a subband based on PUCCH resources and / or PUSCH resources configured for a BWP.

[0079] Specifically, Figure 5 is a flow chart illustrating an exemplary method 500 for UL transmission in a full-duplex system according to some embodiments of the present disclosure. Figure 5 The method in may be performed by a UE (eg, Figure 1 The invention is implemented by the UE 101 shown in FIG.

[0080] exist Figure 5 In the exemplary method shown in FIG. 5 , in step 501, the UE may receive a signal from a BS (e.g., Figure 1 BS 102 shown in FIG. 1 receives a configuration indicating one or more resource sets for a BWP of a UE. In step 503, the UE may determine at least one available resource set for a subband based on the one or more resource sets for the BWP.

[0081] In some embodiments of the present disclosure, a subband is associated with a BWP. In an embodiment of the present disclosure, when a configuration for a subband (e.g., a subband configuration) is within a configuration for a BWP (e.g., a BWP configuration), the subband is associated with a BWP. In an embodiment of the present disclosure, when a subband is configured separately (i.e., the configuration for a subband is separate from the configuration for a BWP), the subband is associated with a BWP, and the subband is within the region of the BWP. In an embodiment of the present disclosure, a UE may receive a configuration indicating that a subband is associated with a BWP from a BS.

[0082] According to some embodiments of the present disclosure, resources may be configured for transmitting PUCCH in a BWP. For example, PUCCH may be used to transmit uplink control information (UCI), including, for example, hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback, scheduling request (SR), and channel state information (CSI). In such embodiments, one or more resource sets may be one or more PUCCH resource sets for a BWP, wherein each PUCCH resource set may be configured with one or more PUCCH resources for a BWP.

[0083] In some embodiments, the configuration received by the UE in step 501 may include one or more first configurations, wherein each first configuration may indicate a corresponding PUCCH resource set. For example, the first configuration may be indicated by a parameter PUCCH-ResourceSet as specified in the 3GPP specification.

[0084] In an embodiment, each first configuration may indicate an ID of a corresponding PUCCH resource set, a PUCCH resource ID included in the corresponding PUCCH resource set, and a maximum number of UCI information bits that the UE may transmit by using the PUCCH resource set. In some cases, the UE may be configured with up to 4 PUCCH resource sets for UCI feedback.

[0085] In some embodiments, the configuration received by the UE in step 501 may also include one or more second configurations indicating one or more PUCCH resources. The one or more PUCCH resources may be included in a PUCCH resource set. For example, the second configuration may be indicated by a parameter PUCCH-Resource as specified in the 3GPP specification.

[0086] In an embodiment, the second configuration may include at least one of the following parameters:

[0087] A resource ID indicating the ID of the corresponding PUCCH resource (e.g., pucch-ResourceId as specified in the 3GPP specification);

[0088] ·· the index of the first PRB in the first hop of the corresponding PUCCH resource when frequency hopping is configured or in the physical resource of the corresponding PUCCH resource when frequency hopping is not configured (e.g., startingPRB as specified in 3GPP specifications);

[0089] • The index of the first PRB in the second hop of the corresponding PUCCH resource (e.g., index #2) (e.g., secondHopPRB as specified in the 3GPP specification);

[0090] ·· Intra-slot frequency hopping indication indicating whether intra-slot frequency hopping is configured for the UE (e.g., intraSlotFrequencyHopping as specified in the 3GPP specification). For example, intraSlotFrequencyHopping being configured as "enabled" may mean that intra-slot frequency hopping has been configured for the UE; and intraSlotFrequencyHopping being configured as "disabled" may mean that intra-slot frequency hopping is not configured for the UE.

[0091] When intra-slot frequency hopping is configured for a UE, the UE may transmit PUCCH in physical resources for a first hop (starting from a PRB indicated by index #1) and in physical resources for a second hop (starting from a PRB indicated by index #2) in the same slot.

[0092] • A PUCCH format indication indicating the PUCCH format of the corresponding PUCCH resource (eg, format as specified in 3GPP specifications).

[0093] In some embodiments, the PUCCH may be configured with a repetition number (denoted as N_rep), for example, N_rep may be 1, 2, 4, or 8. After receiving the configuration, the UE may repeat the PUCCH transmission within N_rep time units (e.g., time slots). The PUCCH transmission within each of the N_rep time units may have the same starting symbol.

[0094] In some embodiments, in addition to the intra-slot frequency hopping indication, the UE may also receive an inter-slot frequency hopping indication indicating whether inter-slot frequency hopping is configured (e.g., interslotFrequencyHopping as specified in the 3GPP specification). For example, interslotFrequencyHopping being configured as "enabled" may mean that inter-slot frequency hopping has been configured for the UE; and interslotFrequencyHopping being configured as "disabled" may mean that inter-slot frequency hopping is not configured for the UE. If inter-slot frequency hopping is configured for the UE, the UE may perform frequency hopping per time unit (e.g., per time slot). For example, the UE may transmit a PUCCH in a physical resource for a first hop (which starts from the PRB indicated by index #1) in an even time unit among a plurality of time units and transmit a PUCCH in a physical resource for a second hop (which starts from the PRB indicated by index #1) in an odd time unit among a plurality of time units. In the above example, the number of time units in the plurality of time units may refer to the above-described N_rep for transmitting PUCCH repetitions.

[0095] After receiving the configuration in step 501, the UE may determine at least one available PUCCH resource set for the subband based on the one or more PUCCH resource sets for the BWP in step 503. The UE may determine at least one available PUCCH resource for the subband in the at least one available PUCCH resource set for the subband.

[0096] In some embodiments, in the case where at least one PUCCH resource in a PUCCH resource set is available for a subband, the UE may determine a PUCCH resource set for a BWP as an available PUCCH resource set for the subband.

[0097] The following embodiments provide several methods for determining whether PUCCH resources are available for a subband.

[0098] In an embodiment of the present disclosure, frequency hopping (e.g., both intra-slot frequency hopping and inter-slot frequency hopping) may not be configured for the UE. In this embodiment, when the physical resource of the PUCCH resource in the PUCCH resource set for the BWP is within the subband, the UE may determine the PUCCH resource as an available PUCCH resource for the subband. In this embodiment, the first PRB of the physical resource herein may be indicated by the index #1 included in the corresponding second configuration of the PUCCH resource as stated above. The size of the physical resource (i.e., the number of PRBs included in the physical resource) may be determined based on the PUCCH format of the PUCCH resource indicated by the second configuration.

[0099] In an embodiment of the present disclosure, frequency hopping (e.g., intra-slot hopping or inter-slot hopping) may be configured for the UE. In some instances, in the case where only the physical resources for the first hop of the PUCCH resources are within the subband, the UE may determine the PUCCH resources in the PUCCH resource set for the BWP as the available PUCCH resources for the subband. In some instances, in the case where only the physical resources for the second hop of the PUCCH resources are within the subband, the UE may determine the PUCCH resources in the PUCCH resource set for the BWP as the available PUCCH resources for the subband. In some instances, in the case where both the physical resources for the first hop of the PUCCH resources and the physical resources for the second hop of the PUCCH resources are within the subband, the UE may determine the PUCCH resources in the PUCCH resource set for the BWP as the available PUCCH resources for the subband.

[0100] In this embodiment, the first PRB of the physical resource for the first hop may be indicated by the index #1 included in the corresponding second configuration of the PUCCH resource as stated above. The first PRB of the physical resource for the second hop may be indicated by the index #2 included in the second configuration of the PUCCH resource as stated above. The size of the physical resource for the first hop and the second hop (i.e., the number of PRBs included in the physical resource) may be determined based on the PUCCH format of the PUCCH resource indicated by the second configuration.

[0101] In an embodiment of the present disclosure, a subband may be configured with one or more PUCCH resources. For example, the configuration for a subband may include one or more resource IDs of one or more PUCCH resources. In this embodiment, in a case where the resource ID of a PUCCH resource in a PUCCH resource set for a BWP is the same as the resource ID of a PUCCH resource configured for a subband, the UE may determine the PUCCH resource set for the BWP as the available PUCCH resource set for the subband. In such embodiments, although the PUCCH resources for the BWP have the same ID as the PUCCH resources for the subband, their configuration may be different. For example, they may have different starting PRBs, second hop PRBs, PUCCH formats, etc.

[0102] In this embodiment, for PUCCH transmission in a subband, the UE may overwrite the PUCCH resources configured for the BWP with the PUCCH resources configured for the subband.

[0103] Based on the above method, the UE may determine the PUCCH resources available for the subband. In some embodiments of the present disclosure, the available PUCCH resource set for the subband determined by the UE may not include PUCCH resources with resource IDs not included in the PUCCH resource set for the BWP associated with the subband.

[0104] In some embodiments of the present disclosure, in the case where a PUCCH resource set does not include any PUCCH resources available for a subband (in other words, there are no PUCCH resources available for a subband in the PUCCH resource set), the PUCCH resource set is not available for the subband. When this PUCCH resource set is used to transmit a PUCCH, the PUCCH cannot be transmitted in the subband.

[0105] In some embodiments of the present disclosure, if a PUCCH is indicated to be transmitted in a PUCCH resource, and the PUCCH resource is not available in a subband, then the PUCCH cannot be transmitted in the subband.

[0106] Figure 6 An exemplary method for determining a PUCCH resource set and PUCCH resources according to some embodiments of the present disclosure is illustrated.

[0107] refer to Figure 6 , assuming that the UE is configured with a PUCCH resource set #K for the UE's BWP and the PUCCH resource set #K includes five PUCCH resources with resource IDs #a, #b, #c, #d and #e respectively.

[0108] The UE may determine that PUCCH resource #a is available for the subband because the physical resources of PUCCH resource #a are completely within the subband. For example, the physical resources of the first hop for PUCCH resource #a and the physical resources of the second hop for PUCCH resource #a are both completely within the subband.

[0109] The UE may determine that PUCCH resource #b is available for the subband because the physical resources of PUCCH resource #b are partially within the subband. For example, only the physical resources for the first hop of PUCCH resource #b are within the subband but the physical resources for the second hop of PUCCH resource #b are not within the subband.

[0110] The UE may determine that PUCCH resource #c is available for the subband because the physical resources of PUCCH resource #c are partially within the subband. For example, only the physical resources for the second hop of PUCCH resource #c are within the subband but the physical resources for the first hop of PUCCH resource #c are not within the subband.

[0111] The UE can determine that PUCCH resource #d is available for the subband because the PUCCH resource configured separately for the subband also indicates the resource ID of #d. For PUCCH transmission in the subband, the UE can cover the PUCCH resource #d in the PUCCH resource set #K for the BWP with the PUCCH resource #d configured for the subband.

[0112] The UE may determine that PUCCH resource #e for BWP is not available for the subband because the physical resources of PUCCH resource #e are not within the subband and there is no PUCCH resource configured separately for the subband with the same resource ID as PUCCH resource #e.

[0113] Since the four PUCCH resources in the PUCCH resource set #K for BWP are available for the subband, the UE can determine that the PUCCH resource set #K for BWP is the available PUCCH resource set for the subband, and the available PUCCH resources for the subband are PUCCH resources #a, PUCCH resources #b and PUCCH resources #c in the PUCCH resource set #K for BWP and the PUCCH resources #d configured for the subband.

[0114] After determining the available PUCCH resource set and available PUCCH resources for the subband, when the PUCCH is indicated to be transmitted in the PUCCH resources available for the subband, the UE may transmit the PUCCH in the PUCCH resources based on the solutions provided in the following embodiments.

[0115] In some embodiments, frequency hopping (e.g., both intra-slot frequency hopping and inter-slot frequency hopping) may not be configured for the UE. For PUCCH resources determined as available PUCCH resources for a subband (e.g., the physical resources of the PUCCH resources are within the subband), the UE may transmit the PUCCH in the physical resources in the subband within one or more time units. In embodiments of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0116] In some embodiments, in the case where only the physical resources for the first hop of the PUCCH resources are within the subband, the PUCCH may be determined as an available PUCCH resource for the subband. Regardless of whether frequency hopping is configured for the UE, the UE may transmit the PUCCH in the physical resources for the first hop in the subband within one or more time units without frequency hopping. In embodiments of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0117] For example, even when intra-slot frequency hopping is configured for the UE, the UE may transmit PUCCH in physical resources for the first hop in the subband within one or more time units without performing intra-slot frequency hopping. In another example, even when inter-slot frequency hopping is configured for the UE, the UE may transmit PUCCH in physical resources for the first hop in the subband within one or more time units without performing inter-slot frequency hopping.

[0118] If the PUCCH is indicated to be transmitted in the PUCCH resources in the time unit configured with the subband, the PUCCH may be transmitted in the physical resources determined for the PUCCH resources in the subband.

[0119] If the PUCCH is indicated to be transmitted repeatedly in the PUCCH resources, then depending on the configured number of repetitions, the repetition may occur in a time unit, which may include one or more time units configured with a subband, and may also include one or more time units configured with a BWP (i.e., UL time units). For PUCCH transmissions in a time unit configured with a subband, the repetition may occur in the physical resources determined for the PUCCH resources in the subband.

[0120] Figure 7 An exemplary PUSCH transmission method according to some embodiments of the present disclosure is illustrated.

[0121] refer to Figure 7 , assuming that: the PUCCH is configured with N_rep=4 repetitions; the PUCCH is indicated as being transmitted in a PUCCH resource, wherein the PUCCH resource is configured with index #1 of the first PRB in the first hop and index #2 of the first PRB in the second hop; the PUCCH is indicated as being transmitted starting from time slot #k; and inter-slot hopping is configured for the UE.

[0122] N_rep = 4 repetitions means that the PUCCH can be repeatedly transmitted in four consecutive time slots. Figure 7 In the example of , it is further assumed that time slot #k and time slot #k+1 are DL time slots configured with UL subbands and time slot #k+2 and time slot #k+3 are UL time slots.

[0123] After receiving the above PUCCH configuration, the UE may determine whether the PUCCH resources for the BWP are available for the subband associated with the BWP. Figure 7 In the example of , it is assumed that only the physical resource for the first hop of the PUCCH resource (physical resource #A1) is within the subband and the physical resource for the second hop of the PUCCH resource (physical resource #A2) is not within the subband.

[0124] Then, in slot #k and slot #k+1, the UE may transmit the PUCCH in physical resource #A1 in the subband (i.e., starting from the PRB with index #1) without performing inter-slot hopping. In slot #k+2 and slot #k+3, the UE may transmit the PUCCH by inter-slot hopping. For example, the UE may transmit the PUCCH in physical resource #A1 in slot #k+2 and in physical resource #A2 in slot #k+3.

[0125] In some embodiments, in the case where only the physical resources for the second hop of the PUCCH resources are within the subband, the PUCCH may be determined as an available PUCCH resource for the subband. Regardless of whether frequency hopping is configured for the UE, the UE may transmit the PUCCH in the physical resources for the second hop in the subband within one or more time units without frequency hopping. In embodiments of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0126] For example, even when intra-slot frequency hopping is configured for the UE, the UE may transmit the PUCCH in the physical resources for the second hop in the subband within one or more time units without performing intra-slot frequency hopping. In another example, even when inter-slot frequency hopping is configured for the UE, the UE may transmit the PUCCH in the physical resources for the second hop in the subband within one or more time units without performing inter-slot frequency hopping.

[0127] Figure 8 An exemplary PUSCH transmission method according to some embodiments of the present disclosure is illustrated.

[0128] refer to Figure 8, assuming that: the PUCCH is configured with N_rep=4 repetitions; the PUCCH is indicated to be transmitted in the PUCCH resources for the BWP, wherein the PUCCH resources are configured with index #1 of the first PRB in the first hop and index #2 of the first PRB in the second hop; the PUCCH is indicated to be transmitted starting from time slot #k; and inter-slot hopping is configured for the UE.

[0129] N_rep = 4 repetitions means that the PUCCH can be repeatedly transmitted in four consecutive time slots. Figure 8 In the example of , it is further assumed that time slot #k and time slot #k+1 are DL time slots configured with UL subbands and time slot #k+2 and time slot #k+3 are UL time slots.

[0130] After receiving the above PUCCH configuration, the UE may determine whether the PUCCH resources for the BWP are available for the subband associated with the BWP. Figure 8 In the example of , it is assumed that only the physical resource for the second hop of the PUCCH resource (physical resource #B2) is within the subband and the physical resource for the first hop of the PUCCH resource (physical resource #B1) is not within the subband.

[0131] Then, in slot #k and slot #k+1, the UE may transmit the PUCCH in physical resource #B2 in the subband (i.e., starting from the PRB with index #2) without performing inter-slot hopping. In slot #k+2 and slot #k+3, the UE may transmit the PUCCH by inter-slot hopping. For example, the UE may transmit the PUCCH in physical resource #B1 in slot #k+2 and in physical resource #B2 in slot #k+3.

[0132] In some embodiments, in the case where both the physical resources of the first hop for the PUCCH resource and the physical resources of the second hop for the PUCCH resource are within the subband, the PUCCH may be determined as an available PUCCH resource for the subband. When frequency hopping is configured for the UE, the UE may transmit the PUCCH in the physical resources for the first hop and the physical resources for the second hop in the subband within one or more time units by frequency hopping. In the embodiments of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0133] For example, when intra-slot frequency hopping is configured for the UE, the UE may transmit the PUCCH in the physical resources for the first hop and the physical resources for the second hop in the subband within the same time unit. When inter-slot frequency hopping is configured for the UE, the UE may transmit the PUCCH in the physical resources for the first hop in the subband within a time unit having an even number among a set of consecutive time units, and transmit the PUCCH in the physical resources for the second hop in the subband within a time unit having an odd number among the set of consecutive time units. The number of time units in the set of consecutive time units may be N_rep configured for transmission PUCCH repetition.

[0134] Fig. 9 An exemplary PUSCH transmission method according to some embodiments of the present disclosure is illustrated.

[0135] refer to Fig. 9 , assuming that: the PUCCH is configured with N_rep=4 repetitions; the PUCCH is indicated to be transmitted in the PUCCH resources for the BWP, wherein the PUCCH resources are configured with index #1 of the first PRB in the first hop and index #2 of the first PRB in the second hop; the PUCCH is indicated to be transmitted starting from time slot #k; and inter-slot hopping is configured for the UE.

[0136] N_rep = 4 repetitions means that the PUCCH can be repeatedly transmitted in four consecutive time slots. Fig. 9 In the example of , it is further assumed that time slot #k and time slot #k+1 are DL time slots configured with subbands and time slot #k+2 and time slot #k+3 are UL time slots.

[0137] After receiving the above PUCCH configuration, the UE may determine whether the PUCCH resources for the BWP are available for the subband associated with the BWP. Fig. 9 In the example of , it is assumed that both the physical resource #C1 for the first hop and the physical resource #C2 for the second hop are within the subband.

[0138] Then, in time slot #k and time slot #k+1, the UE may transmit PUCCH in physical resource #C1 and physical resource #C2 in the subband by performing inter-slot frequency hopping. For example, the UE may transmit PUCCH in physical resource #C1 in time slot #k and in physical resource #C2 in time slot #k+1. In time slot #k+2 and time slot #k+3, the UE may also transmit PUCCH by inter-slot frequency hopping. For example, the UE may transmit PUCCH in physical resource #C1 in time slot #k+2 and in physical resource #C2 in time slot #k+3.

[0139] In some embodiments, in a case where the resource ID of a PUCCH resource in a PUCCH resource set is the same as the resource ID of a PUCCH resource configured for a subband (expressed as "another PUCCH resource" for clarity), the PUCCH resource set for the BWP may be determined as the available PUCCH resource set for the subband.

[0140] Then, in the case where another PUCCH resource includes only physical resources for the first hop, the UE may transmit PUCCH in the physical resources for the first hop in the subband without frequency hopping within one or more time units regardless of whether frequency hopping is configured for the UE.

[0141] In the case where another PUCCH resource includes only physical resources for the second hop, the UE may transmit the PUCCH in the physical resources for the second hop in the subband within one or more time units without frequency hopping regardless of whether frequency hopping is configured for the UE.

[0142] In the case where another PUCCH resource includes both a physical resource for a first hop and a physical resource for a second hop, when frequency hopping is configured for the UE, the UE may transmit the PUCCH in the physical resource for the first hop and the second physical resource for the second hop in the subband within one or more time units by frequency hopping. For example, when intra-slot frequency hopping is configured for the UE, the UE may transmit the PUCCH in the physical resource for the first hop and the physical resource for the second hop in the subband within the same time unit. When inter-slot frequency hopping is configured for the UE, the UE may transmit the PUCCH in the physical resource for the first hop in the subband within a time unit having an even number among a group of consecutive time units, and transmit the PUCCH in the physical resource for the second hop in the subband within a time unit having an odd number among the group of consecutive time units. The number of time units in the group of consecutive time units may be N_rep configured for transmission PUCCH repetition. In an embodiment of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0143] Fig.10 An exemplary PUSCH transmission method according to some embodiments of the present disclosure is illustrated.

[0144] refer to Fig.10 , assuming that: the PUCCH is configured with N_rep=4 repetitions; the PUCCH is indicated as being transmitted in a PUCCH resource, wherein the PUCCH resource is configured with index #1 of the first PRB in the first hop and index #2 of the first PRB in the second hop; the PUCCH is indicated as being transmitted starting from time slot #k; and inter-slot hopping is configured for the UE.

[0145] N_rep = 4 repetitions means that the PUCCH can be repeatedly transmitted in four consecutive time slots. Fig.10 In the example of , it is further assumed that time slot #k and time slot #k+1 are DL time slots configured with UL subbands and time slot #k+2 and time slot #k+3 are UL time slots.

[0146] After receiving the above PUCCH configuration, the UE may determine whether a PUCCH resource set including PUCCH resources for the BWP is available for the subband associated with the BWP. Fig.10 In the example of , it is assumed that both the physical resource #D1 for the first hop of the PUCCH resource and the physical resource #D2 for the second hop of the PUCCH resource are outside the subband. In some other examples, one or both of the physical resource #D1, the physical resource #D2 may be within the subband. The resource ID of the PUCCH resource for the BWP is the same as the resource ID of the PUCCH resource configured for the subband (expressed as "another PUCCH resource" for clarity). The UE may determine that a PUCCH resource set including the PUCCH resource for the BWP is available for the subband. It is assumed that only the index of the first PRB in the first hop (e.g., index #3) is configured for the another PUCCH resource. That is, the another PUCCH resource includes only the physical resource #E1 for the first hop or for non-frequency hopping.

[0147] Then, in slot #k and slot #k+1, the UE may cover the PUCCH resource for BWP with another PUCCH resource for the subband. For example, in slot #k and slot #k+1, the UE may transmit PUCCH in physical resource #E1 in the subband without performing inter-slot frequency hopping. In slot #k+2 and slot #k+3, the UE may transmit PUCCH by inter-slot frequency hopping. For example, the UE may transmit PUCCH in physical resource #D1 in slot #k+2 and in physical resource #D2 in slot #k+3.

[0148] Fig.11 An exemplary PUCCH transmission method according to some embodiments of the present disclosure is illustrated.

[0149] refer to Fig.11 , assuming that: the PUCCH is configured with N_rep=4 repetitions; the PUCCH is indicated to be transmitted in the PUCCH resources for the BWP, wherein the PUCCH resources are configured with index #1 of the first PRB in the first hop and index #2 of the first PRB in the second hop; the PUCCH is indicated to be transmitted starting from time slot #k; and inter-slot hopping is configured for the UE.

[0150] N_rep = 4 repetitions means that the PUCCH can be repeatedly transmitted in four consecutive time slots. Fig.11 In the example of , it is further assumed that time slot #k and time slot #k+1 are DL time slots configured with UL subbands and time slot #k+2 and time slot #k+3 are UL time slots.

[0151] After receiving the above PUCCH configuration, the UE may determine whether a PUCCH resource set including PUCCH resources for the BWP is available for the subband associated with the BWP. Fig.11 In the example of , it is assumed that both the physical resource #F1 for the first hop of the PUCCH resource and the physical resource #F2 for the second hop of the PUCCH resource are outside the subband. In some other examples, one or both of the physical resource #F1, the physical resource #F2 may be within the subband. The resource ID of the PUCCH resource for the BWP is the same as the resource ID of the PUCCH resource configured for the subband (denoted as "another PUCCH resource" for clarity). The UE may determine that a PUCCH resource set including the PUCCH resource for the BWP is available for the subband. It is assumed that the index of the first PRB in the first hop (e.g., index #3) and the index of the first PRB in the second hop (e.g., index #4) are configured for the other PUCCH resource. That is, the other PUCCH resource includes the physical resource #G1 for the first hop and the physical resource #G2 for the second hop.

[0152] Then, in time slot #k and time slot #k+1, the UE may cover the PUCCH resource for BWP with another PUCCH resource for the subband. For example, in time slot #k and time slot #k+1, the UE may transmit PUCCH in physical resource #G1 and physical resource #G2 in the subband by inter-slot hopping. For example, the UE may transmit PUCCH in physical resource #G1 in time slot #k and in physical resource #G2 in time slot #k+1. In time slot #k+2 and time slot #k+3, the UE may transmit PUCCH in physical resource #F1 and physical resource #F2 by inter-slot hopping. For example, the UE may transmit PUCCH in physical resource #F1 in time slot #k+2 and in physical resource #F2 in time slot #k+3.

[0153] The above embodiments provide solutions on how to determine an available PUCCH resource set and available PUCCH resources for a subband. In some embodiments, a PUCCH resource set may be used to transmit a PUCCH carrying, for example, HARQ-ACK feedback.

[0154] Although the above embodiments are described for a PUCCH resource set, it should be noted that the PUCCH resource set as described may include only a single PUCCH resource. Or there may be no such PUCCH resource set configuration, but only PUCCH resources configured for PUCCH feedback. The above description may also be applied to this situation. For example, according to some embodiments of the present disclosure, the configuration received in step 501 may indicate a single PUCCH resource for PUCCH feedback. The PUCCH resource may be used to transmit a PUCCH carrying, for example, SR or CSI. For example, the configuration in step 501 may include only the second configuration as stated above, and the second configuration may indicate a single PUCCH resource. In such embodiments, determining at least one available resource set for a subband based on one or more resource sets for a BWP in step 503 may mean determining whether a single PUCCH resource for a BWP is an available PUCCH resource for a subband. All of the above methods for determining whether a PUCCH resource for a BWP is an available PUCCH resource for a subband may be applied here. In addition, all the above methods for transmitting PUCCH in PUCCH resources available for a subband may also be applied here.

[0155] The above embodiments may provide a solution on how to determine available PUCCH resources for a subband. A similar method may be used to determine available PUSCH resources for a subband.

[0156] For example, according to some embodiments of the present disclosure, the configuration received by the UE in step 501 may be used for PUSCH resource allocation. For example, the configuration may be a DCI indicating a PRB set of a PUSCH.

[0157] In some embodiments of the present disclosure, frequency hopping (e.g., both intra-slot hopping and inter-slot hopping) may not be configured for the UE. In this embodiment, in the case where the PRB set is within a subband, the UE may determine the PRB set as the set of available PUSCH resources for the subband. The UE may transmit the PUSCH in the PRB set in the subband within one or more time units. In embodiments of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0158] In some embodiments, the UE may receive another configuration indicating a PRB offset value for the PUSCH. In such embodiments, in the case where frequency hopping is configured for the UE, the UE may determine the physical resources for the first hop of the PUSCH and the physical resources for the second hop of the PUSCH based on the starting PRB of the PRB set and the PRB offset value. In such embodiments, the one or more resource sets determined based on the DCI may include two PUSCH resource sets, one set for the physical resources for the first hop and the other set for the physical resources for the second hop.

[0159] For example, the physical resources for the first hop may be a PRB set indicated by the DCI as stated above. The index of the starting PRB of the physical resources for the second hop may be determined based on the starting PRB of the PRB set indicated by the DCI and the PRB offset value, for example according to the formula mod(startingPRB+RB_offset,N_BWP), where the parameter "startingPRB" is the index of the starting PRB of the PRB set indicated by the DCI, the parameter RB_offset is the PRB offset value indicated by another configuration, and the parameter N_BWP is the number of PRBs of the BWP. The number of PRBs included in the physical resources for the second hop may be the same as the number of PRBs in the PRB set.

[0160] In an embodiment, in the case where only the physical resources for the first hop are within the subband, the UE may determine the physical resources for the first hop as an available PUSCH resource set for the subband. Regardless of whether frequency hopping is configured for the UE, the UE may transmit the PUSCH in the physical resources for the first hop in the subband within one or more time units without frequency hopping. In an embodiment of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0161] For example, even when intra-slot frequency hopping is configured for the UE, the UE may transmit PUSCH in physical resources for the first hop in the subband within one or more time units without performing intra-slot frequency hopping. In another example, even when inter-slot frequency hopping is configured for the UE, the UE may transmit PUSCH in physical resources for the first hop in the subband within one or more time units without performing inter-slot frequency hopping.

[0162] In an embodiment, in the case where only the physical resources for the second hop are within the subband, the UE may determine the physical resources for the second hop as an available PUSCH resource set for the subband. Regardless of whether frequency hopping is configured for the UE, the UE may transmit the PUSCH in the physical resources for the second hop in the subband within one or more time units without frequency hopping. In an embodiment of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0163] For example, even when intra-slot frequency hopping is configured for the UE, the UE may transmit PUSCH in physical resources for the second hop in the subband within one or more time units without performing intra-slot frequency hopping. In another example, even when inter-slot frequency hopping is configured for the UE, the UE may transmit PUSCH in physical resources for the second hop in the subband within one or more time units without performing inter-slot frequency hopping.

[0164] In an embodiment, in the case where both the physical resources for the first hop and the physical resources for the second hop are within the subband, the UE may determine the physical resources for the first hop and the physical resources for the second hop as an available PUSCH resource set for the subband.

[0165] When frequency hopping is configured for the UE, the UE may transmit the PUSCH in the physical resources for the first hop and the physical resources for the second hop in the subband within one or more time units by frequency hopping. In the embodiments of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0166] For example, when intra-slot frequency hopping is configured for the UE, the UE may transmit the PUSCH in the physical resources for the first hop and the physical resources for the second hop in the subband within the same time unit. When inter-slot frequency hopping is configured for the UE, the UE may transmit the PUSCH in the physical resources for the first hop in the subband within a time unit having an even number among a set of consecutive time units, and transmit the PUCCH in the physical resources for the second hop in the subband within a time unit having an odd number among the set of consecutive time units. The number of time units in the set of consecutive time units may be equal to the number of repetitions configured for the PUSCH.

[0167] According to some embodiments of the present disclosure, the above solution for determining a resource set and resources for PUCCH transmission in a subband may also be applied to determining a resource set and resources for Sounding Reference Signal (SRS) transmission in a subband.

[0168] It should be understood that although terms such as "inter-time slot" and "intra-time slot" hopping are used for simplicity in the context of the present disclosure, these terms can be replaced with "inter-time unit" and "intra-time unit" hopping without departing from the spirit and scope of the present disclosure.

[0169] Fig.12 is a flow chart illustrating an exemplary method 1200 for UL transmission in a full-duplex system according to some embodiments of the present disclosure. Fig.12 The method in can be implemented by BS (e.g., Figure 1 BS102) shown in FIG.

[0170] exist Fig.12 In the exemplary method shown in FIG. 1 , in step 1201, the BS may send a signal to the UE (eg, Figure 1 UE 101 shown in FIG. 101 transmits a configuration indicating one or more resource sets for a BWP of the UE. In step 1203, the BS may determine at least one available resource set for a subband based on the one or more resource sets for the BWP.

[0171] In some embodiments of the present disclosure, a subband is associated with a BWP. In an embodiment of the present disclosure, when a configuration for a subband (e.g., a subband configuration) is within a configuration for a BWP (e.g., a BWP configuration), the subband is associated with a BWP. In an embodiment of the present disclosure, when a subband is configured separately (i.e., the configuration for a subband is separate from the configuration for a BWP), the subband is associated with a BWP, and the subband is within the region of the BWP. In an embodiment of the present disclosure, the BS may transmit a configuration indicating that a subband is associated with a BWP to a UE.

[0172] According to some embodiments of the present disclosure, resources may be configured for transmitting PUCCH in a BWP. In such embodiments, one or more resource sets may be one or more PUCCH resource sets for a BWP, wherein each PUCCH resource set may be configured with one or more PUCCH resources for a BWP.

[0173] In some embodiments, the configuration transmitted by the BS in step 1201 may include one or more first configurations and one or more second configurations. Figure 5 The descriptions of the first configuration and the second configuration are applicable here and are therefore omitted here.

[0174] In step 1203, the BS may determine at least one available PUCCH resource set for the subband based on one or more PUCCH resource sets for the BWP. The BS may determine at least one available PUCCH resource for the subband in the at least one available PUCCH resource set for the subband.

[0175] In some embodiments, in the case where at least one PUCCH resource in a PUCCH resource set is available for a subband, the BS may determine a PUCCH resource set for a BWP as an available PUCCH resource set for the subband.

[0176] The following embodiments provide several methods for determining whether PUCCH resources are available for a subband.

[0177] In an embodiment of the present disclosure, frequency hopping (e.g., both intra-slot frequency hopping and inter-slot frequency hopping) may not be configured for the UE. In this embodiment, when the physical resource of the PUCCH resource in the PUCCH resource set for the BWP is within the subband, the BS may determine the PUCCH resource as an available PUCCH resource for the subband. In this embodiment, the first PRB of the physical resource herein may be indicated by the index #1 included in the corresponding second configuration of the PUCCH resource as stated above. The size of the physical resource (i.e., the number of PRBs included in the physical resource) may be determined based on the PUCCH format of the PUCCH resource indicated by the second configuration.

[0178] In an embodiment of the present disclosure, frequency hopping (e.g., intra-slot hopping or inter-slot hopping) may be configured for the UE. In some instances, in a case where only the physical resources for the first hop of the PUCCH resources are within the subband, the BS may determine the PUCCH resources in the PUCCH resource set for the BWP as the available PUCCH resources for the subband. In some instances, in a case where only the physical resources for the second hop of the PUCCH resources are within the subband, the BS may determine the PUCCH resources in the PUCCH resource set for the BWP as the available PUCCH resources for the subband. In some instances, in a case where both the physical resources for the first hop of the PUCCH resources and the physical resources for the second hop of the PUCCH resources are within the subband, the BS may determine the PUCCH resources in the PUCCH resource set for the BWP as the available PUCCH resources for the subband.

[0179] In this embodiment, the first PRB of the physical resource for the first hop may be indicated by the index #1 included in the corresponding second configuration of the PUCCH resource as stated above. The first PRB of the physical resource for the second hop may be indicated by the index #2 included in the second configuration of the PUCCH resource as stated above. The size of the physical resource for the first hop and the second hop (i.e., the number of PRBs included in the physical resource) may be determined based on the PUCCH format of the PUCCH resource indicated by the second configuration.

[0180] In an embodiment of the present disclosure, the BS may configure one or more PUCCH resources for a subband. For example, the configuration for a subband may include one or more resource IDs of one or more PUCCH resources. In this embodiment, in a case where the resource ID of a PUCCH resource in a PUCCH resource set for a BWP is the same as the resource ID of a PUCCH resource configured for a subband, the BS may determine the PUCCH resource set for the BWP as an available PUCCH resource set for the subband. In such an embodiment, although the PUCCH resources for the BWP have the same ID as the PUCCH resources for the subband, their configuration may be different. For example, they may have different starting PRBs, second hop PRBs, PUCCH formats, etc.

[0181] In this embodiment, for PUCCH transmission in a subband, the BS may cover PUCCH resources configured for the BWP with PUCCH resources configured for the subband.

[0182] Based on the above method, the BS may determine PUCCH resources available for the subband. In some embodiments of the present disclosure, the available PUCCH resource set for the subband determined by the BS may not include PUCCH resources having resource IDs not included in the PUCCH resource set for the BWP associated with the subband.

[0183] In some embodiments of the present disclosure, in the case where a PUCCH resource set does not include any PUCCH resources available for a subband (in other words, there are no PUCCH resources available for a subband in the PUCCH resource set), the PUCCH resource set is not available for the subband. When this PUCCH resource set is used to receive a PUCCH, the PUCCH will not be received in the subband.

[0184] In some embodiments of the present disclosure, if a PUCCH is indicated to be transmitted in a PUCCH resource, and the PUCCH resource is not available in a subband, then the PUCCH will not be received in the subband.

[0185] After determining an available PUCCH resource set and available PUCCH resources for a subband, when a PUCCH is indicated to be transmitted in a PUCCH resource available for the subband, the BS may receive a PUCCH in the PUCCH resources based on a solution provided in the following embodiments.

[0186] In some embodiments, frequency hopping (e.g., both intra-slot frequency hopping and inter-slot frequency hopping) may not be configured for the UE. For PUCCH resources determined as available PUCCH resources for a subband (e.g., physical resources of the PUCCH resources are within the subband), the BS may receive the PUCCH in physical resources in the subband within one or more time units. In embodiments of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0187] In some embodiments, in the case where only the physical resources for the first hop of the PUCCH resources are within the subband, the PUCCH may be determined as an available PUCCH resource for the subband. Regardless of whether frequency hopping is configured for the UE, the BS may receive the PUCCH in the physical resources for the first hop in the subband within one or more time units without frequency hopping. In embodiments of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0188] For example, even when intra-slot frequency hopping is configured for the UE, the BS may receive the PUCCH in the physical resources for the first hop in the subband within one or more time units without performing intra-slot frequency hopping. In another example, even when inter-slot frequency hopping is configured for the UE, the BS may receive the PUCCH in the physical resources for the first hop in the subband within one or more time units without performing inter-slot frequency hopping.

[0189] In some embodiments, in the case where only the physical resources for the second hop of the PUCCH resources are within the subband, the PUCCH may be determined as an available PUCCH resource for the subband. Regardless of whether frequency hopping is configured for the UE, the BS may receive the PUCCH in the physical resources for the second hop in the subband within one or more time units without frequency hopping. In embodiments of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0190] For example, even when intra-slot frequency hopping is configured for the UE, the BS may receive the PUCCH in the physical resources for the second hop in the subband within one or more time units without performing intra-slot frequency hopping. In another example, even when inter-slot frequency hopping is configured for the UE, the BS may receive the PUCCH in the physical resources for the second hop in the subband within one or more time units without performing inter-slot frequency hopping.

[0191] In some embodiments, in the case where both the physical resources of the first hop for the PUCCH resource and the physical resources of the second hop for the PUCCH resource are within the subband, the PUCCH may be determined as an available PUCCH resource for the subband. When frequency hopping is configured for the UE, the BS may receive the PUCCH in the physical resources for the first hop and the physical resources for the second hop in the subband within one or more time units by frequency hopping. In an embodiment of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0192] For example, when intra-slot frequency hopping is configured for the UE, the BS may receive the PUCCH in the physical resources for the first hop and the physical resources for the second hop in the subband within the same time unit. When inter-slot frequency hopping is configured for the UE, the BS may receive the PUCCH in the physical resources for the first hop in the subband within a time unit having an even number among a set of consecutive time units, and receive the PUCCH in the physical resources for the second hop in the subband within a time unit having an odd number among the set of consecutive time units. The number of time units in the set of consecutive time units may be N_rep configured for transmission PUCCH repetition.

[0193] In some embodiments, in a case where the resource ID of a PUCCH resource in a PUCCH resource set is the same as the resource ID of a PUCCH resource configured for a subband (expressed as "another PUCCH resource" for clarity), the PUCCH resource set for the BWP may be determined as the available PUCCH resource set for the subband.

[0194] Then, in the case where another PUCCH resource includes only physical resources for the first hop, the BS can receive PUCCH in the physical resources for the first hop in the subband without frequency hopping within one or more time units regardless of whether frequency hopping is configured for the UE.

[0195] In case that another PUCCH resource includes only physical resources for the second hop, the BS may receive the PUCCH in the physical resources for the second hop in the subband within one or more time units without frequency hopping regardless of whether frequency hopping is configured for the UE.

[0196] In the case where another PUCCH resource includes both a physical resource for a first hop and a physical resource for a second hop, when frequency hopping is configured for the UE, the UE may transmit the PUCCH in the physical resource for the first hop and the second physical resource for the second hop in the subband within one or more time units by frequency hopping. For example, when intra-slot frequency hopping is configured for the UE, the BS may receive the PUCCH in the physical resource for the first hop and the physical resource for the second hop in the subband within the same time unit. When inter-slot frequency hopping is configured for the UE, the BS may receive the PUCCH in the physical resource for the first hop in the subband within a time unit having an even number among a group of consecutive time units, and receive the PUCCH in the physical resource for the second hop in the subband within a time unit having an odd number among the group of consecutive time units. The number of time units in the group of consecutive time units may be N_rep configured for transmission PUCCH repetition. In an embodiment of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0197] The above embodiments provide solutions on how to determine an available PUCCH resource set and available PUCCH resources for a subband. In some embodiments, a PUCCH resource set may be used to transmit a PUCCH carrying, for example, HARQ-ACK feedback.

[0198] Although the above embodiments are described for a PUCCH resource set, it should be noted that the PUCCH resource set as described may include only a single PUCCH resource. Or there may be no such PUCCH resource set configuration, but only PUCCH resources configured for PUCCH feedback. The above description may also be applied to this situation. For example, according to some embodiments of the present disclosure, the configuration transmitted in step 1201 may indicate a single PUCCH resource for PUCCH feedback. The PUCCH resource may be used to transmit a PUCCH carrying, for example, SR or CSI. For example, the configuration in step 1201 may include only the second configuration as stated above, and the second configuration may indicate a single PUCCH resource. In such embodiments, determining at least one available resource set for a subband based on one or more resource sets for a BWP in step 1203 may mean determining whether a single PUCCH resource for a BWP is an available PUCCH resource for a subband. All of the above methods for determining whether a PUCCH resource for a BWP is an available PUCCH resource for a subband may be applied here. In addition, all the above methods for receiving a PUCCH in a PUCCH resource available for a subband may also be applied here.

[0199] According to some embodiments of the present disclosure, the configuration transmitted by the BS in step 1201 may be used for PUSCH resource allocation. For example, the configuration may be a DCI indicating a PRB set of the PUSCH.

[0200] In some embodiments of the present disclosure, frequency hopping (eg, both intra-slot hopping and inter-slot hopping) may not be configured for the UE. In this embodiment, in the case where a PRB set is within a subband, the BS may determine the PRB set as an available PUSCH resource set for the subband.

[0201] The BS may receive the PUSCH in a PRB set in a subband within one or more time units. In an embodiment of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0202] In some embodiments, the BS may transmit another configuration indicating a PRB offset value for the PUSCH. In such embodiments, in the case where frequency hopping is configured for the UE, the BS may determine the physical resources for the first hop of the PUSCH and the physical resources for the second hop of the PUSCH based on the starting PRB of the PRB set and the PRB offset value. In such embodiments, the one or more resource sets determined based on the DCI may include two PUSCH resource sets, one set is the physical resources for the first hop and the other set is the physical resources for the second hop.

[0203] For example, the physical resources for the first hop may be a PRB set indicated by the DCI as stated above. The index of the starting PRB of the physical resources for the second hop may be determined based on the starting PRB of the PRB set indicated by the DCI and the PRB offset value, for example according to the formula mod(startingPRB+RB_offset,N_BWP), where the parameter "startingPRB" is the index of the starting PRB of the PRB set indicated by the DCI, the parameter RB_offset is the PRB offset value indicated by another configuration, and the parameter N_BWP is the number of PRBs of the BWP. The number of PRBs included in the physical resources for the second hop may be the same as the number of PRBs in the PRB set.

[0204] In an embodiment, in the case where only the physical resources for the first hop are within the subband, the BS may determine the physical resources for the first hop as an available PUSCH resource set for the subband. Regardless of whether frequency hopping is configured for the UE, the BS may receive the PUSCH in the physical resources for the first hop in the subband within one or more time units without frequency hopping. In an embodiment of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0205] For example, even when intra-slot frequency hopping is configured for the UE, the BS may receive the PUSCH in the physical resources for the first hop in the subband within one or more time units without performing intra-slot frequency hopping. In another example, even when inter-slot frequency hopping is configured for the UE, the BS may receive the PUSCH in the physical resources for the first hop in the subband within one or more time units without performing inter-slot frequency hopping.

[0206] In an embodiment, in the case where only the physical resources for the second hop are within the subband, the BS may determine the physical resources for the second hop as an available PUSCH resource set for the subband. Regardless of whether frequency hopping is configured for the UE, the UE may transmit the PUSCH in the physical resources for the second hop in the subband within one or more time units without frequency hopping. In an embodiment of the present disclosure, the time unit may be a time slot, a symbol, etc.

[0207] For example, even when intra-slot frequency hopping is configured for the UE, the BS may receive the PUSCH in the physical resources for the second hop in the subband within one or more time units without performing intra-slot frequency hopping. In another example, even when inter-slot frequency hopping is configured for the UE, the BS may receive the PUSCH in the physical resources for the second hop in the subband within one or more time units without performing inter-slot frequency hopping.

[0208] In an embodiment, in the case where both the physical resources for the first hop and the physical resources for the second hop are within the subband, the BS may determine the physical resources for the first hop and the physical resources for the second hop as an available PUSCH resource set for the subband.

[0209] When frequency hopping is configured for the UE, the BS may receive the PUSCH in the physical resources for the first hop and the physical resources for the second hop in the subband within one or more time units by frequency hopping. In an embodiment of the present disclosure, the time unit may be a time slot, a symbol, or the like.

[0210] For example, when intra-slot frequency hopping is configured for the UE, the BS may receive the PUSCH in the physical resources for the first hop and the physical resources for the second hop in the subband within the same time unit. When inter-slot frequency hopping is configured for the UE, the BS may receive the PUSCH in the physical resources for the first hop in the subband within a time unit having an even number among a set of consecutive time units, and receive the PUCCH in the physical resources for the second hop in the subband within a time unit having an odd number among the set of consecutive time units. The number of time units in the set of consecutive time units may be equal to the number of repetitions configured for the PUSCH.
