[0033] When a time division multiplexing (TDD) configuration of a wireless communication system is configured for use by both a gNodeB (gNB) and a user equipment (UE), configured grant (CG) occasion configurations can be adopted and conflicts between CG occasions and downlink (DL) slots or symbols can be avoided. However, configurations from multiple functions or models (e.g., TDD configuration, CG configuration, SFI (Slot Format Indication) configuration, SSB (SS / PBCH block) configuration, etc.) may not match.

[0034] In some embodiments of the present disclosure, a processing mechanism is discussed when a collision occurs between an uplink control information (UCI) resource or CG occasion and a downlink slot or symbol, and according to such a mechanism, the wireless communication system can become more robust.

[0035] For example, for a CG occasion for PUSCH (Physical Uplink Shared Channel) transmission, if the resource is determined to be invalid based on a certain rule, the transmission may be canceled or postponed. Also, for an UCI (Uplink Control Information) resource for UCI transmission, if the resource is determined to be invalid based on a predetermined standard, the UCI transmission may not be canceled because UCI transmission is essential for releasing over-configured CG resources.

[0036] FIG. 1 shows an example, in which "D" represents a downlink (DL) subframe, "U" represents an uplink (UL) subframe, and "O" represents a CG occasion.

[0037] In Figure 1, the third CG occasion (shown in bold) is considered an invalid CG resource because the third CG occasion conflicts with the downlink subframe. Hereinafter, such an invalid CG resource may be referred to as a conflicting resource, a contention resource, or an overlapping resource.

[0038] In response, the UE may cancel transmission on this occasion. The UE may begin transmission on the next valid CG occasion.

[0039] FIG. 2 shows another example, in which "D" represents a downlink (DL) subframe, "U" represents an uplink (UL) subframe, and "O" represents a CG occasion for transmitting UCI.

[0040] In FIG. 2, the UCI resource (shown in bold) is considered invalid because it collides with a downlink subframe.

[0041] In response, the UE may not cancel the UCI transmission. The UE may transmit the UCI in the first UL symbol of the nearest available UL resource.

[0042] In some embodiments, for configured grant (CG) configurations, periodic UL resources can be pre-configured via RRC signaling, and once an activation DCI activates the CG configuration, UL resource allocation does not require another DCI (UL grant).

[0043] In an embodiment, if a CG PUSCH collides with a DCI grant or a semi-static DL symbol, the UE may not transmit the CG PUSCH.

[0044] In an embodiment, for a CG PUSCH, if a dynamic SFI is not configured and a repetition collides with a semi-static DL symbol, the UE may not send the repetition.

[0045] In an embodiment, for a CG PUSCH, if a dynamic SFI is configured and received and a repeated transmission collides with a dynamic DL / flexible symbol, the UE may not send the repeated transmission.

[0046] In an embodiment, for a CG PUSCH, if a dynamic SFI is not configured and received and a repeated transmission collides with a semi-static DL / flexible symbol, the UE may not send the repeated transmission.

[0047] In some examples, the UCI resource for transmitting UCI is located on a reserved or pre-configured resource (e.g., a PUSCH) to release over-configured resources, as shown in Figure 3. In some examples, the UCI resource is located on a control channel (e.g., a PUCCH) to release over-configured resources, as shown in Figure 4.

[0048] In an embodiment, to avoid potential collisions between UCI resources / CG occasions and downlink slots / symbols, a mechanism for determining invalid UCI resources / CG occasions is provided, and corresponding UE behavior is provided. In an embodiment, the UE transmits UCI in the first UL symbol of the nearest valid UL resource.

[0049] [Example 1] There may be multiple CG occasions in a single CG configuration period. UCI can be transmitted on UCI resources (e.g., UL resources such as PUCCH resources or CG PUSCH resources) and is used to release unused or over-configured resources within the period. For example, the following resource collision cases may exist:

[0050] Case 1: In an embodiment, if a collision occurs between a UCI resource and a semi-statically configured resource, the UE can determine that the UCI resource is invalid (e.g., one or more invalid symbols) and cannot transmit UCI.

[0051] For example, the UE may determine a symbol designated as a downlink resource as an invalid resource (e.g., an invalid symbol), and the symbol designated as a downlink resource may be symbols indicated as downlink symbols by the parameters tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, Symbols designated as SS / PBCH block resources, or The reference cell may include at least one of a symbol configured to receive a PDCCH, a PDSCH, or a CSI-RS in a reference cell (e.g., a serving cell of the UE).

[0052] Case 2: In an embodiment, if a collision occurs between a resource carrying UCI and a downlink resource / channel of dynamic scheduling (e.g., a PDSCH or RS (Reference Signal)), the UE may determine an invalid resource (e.g., one or more symbols) as follows:

[0053] If a symbol in a configured UL resource has a time gap after a dynamically scheduled DL symbol (e.g., PDSCH), and the time gap is smaller than a predetermined time threshold (e.g., N_gap symbols, where N_gap is an integer), such a symbol can be determined as an invalid symbol. In an embodiment, the predetermined time threshold can be determined according to the UE processing capability (e.g., determining N_gap symbols (with a predetermined subcarrier spacing) for a normal XR UE device). In an embodiment, when the subcarrier spacing is 30 kHz, N_gap=2.

[0054] Do not transmit UCI on invalid symbols.

[0055] Case 3: The following paragraphs provide the UE's behavior when it is determined that the UCI resource is invalid.

[0056] In an embodiment, if a UCI resource is determined to be invalid, the UE may not cancel UCI transmission, and may transmit UCI in the first UL symbol of the nearest valid UL resource after the overlapping resource.

[0057] In an embodiment, the UCI is transmitted on a PUCCH or PUSCH resource.

[0058] For example, in an embodiment, the UE may first select a dedicated PUCCH resource to transmit UCI, and then, if the UE determines that the selected PUCCH resource is invalid, the UE may select the next dedicated PUCCH resource after the overlapping resource to use for UCI transmission.

[0059] As another example, in an embodiment, the UE may first select a PUSCH resource to transmit UCI, and then, if the UE determines that the selected PUSCH resource is invalid, the UE may select the next PUSCH resource after the overlapping resource (e.g., the next PUSCH occasion) to use for UCI transmission.

[0060] As another example, in an embodiment, the UE may first select a PUCCH resource to transmit UCI, and then, if the UE determines that the selected PUCCH resource is invalid, the UE may select the closest PUSCH resource (e.g., the closest PUSCH occasion) after the overlapping resource to use for UCI transmission.

[0061] In the examples, the condition that there are one or more redundant CG UL occasions; The condition that the DL resource is in place before or during one or more redundant CG UL occasions, or The time gap between the available UCI resources for transmitting UCI and the first CG UL occasion of one or more redundant CG UL occasions is equal to or greater than a predetermined threshold (e.g., N*2 u slots, where N and u are integers), the UE transmits UCI.

[0062] In the embodiment, N*2 u includes processing time and UL scheduling delay. In an embodiment, N=(1,2,3,4), where u=0 if subcarrier spacing=15 kHz, u=1 if subcarrier spacing=30 kHz, u=2 if subcarrier spacing=60 kHz, u=3 if subcarrier spacing=120 kHz, etc. In an embodiment, the predetermined threshold is N2 milliseconds, where N2 is an integer.

[0063] In an embodiment, if the UCI resource is invalid, the UE may not send a UCI transmission.

[0064] In an embodiment, the UE can determine the first UL symbol of the nearest valid UL resource after the overlapping resource, where the first UL symbol has no or minimal collision with other UEs or UL transmissions.

[0065] Step 1: The UE can identify the valid UL symbol closest to the invalid UCI resource (ie, overlap resource).

[0066] Step 2: In an embodiment, the UE determines that the first UL symbol may be a UL symbol having a predetermined frequency resource and available only for UCI transmission (e.g., the first UL symbol is the first dedicated PUCCH symbol after the overlap resource), and can determine the first UL symbol among the valid UL symbols identified in step 1.

[0067] In an embodiment, the UE may determine that the first UL symbol may be an UL symbol having a predetermined frequency resource and available for UCI transmission (e.g., UCI may be multiplexed with data, and the first UL symbol may be the first symbol of a CG PUSCH occasion after the overlapping resource), and may determine the first UL symbol among the valid UL symbols identified in step 1.

[0068] In an embodiment, for a UE's bandwidth in a UL symbol, the resource may be a UE-specific resource, and the resource must not be occupied by another UL signal transmission.

[0069] In an embodiment, the UCI indicates the release of N CG occasions, where the N CG occasions do not include one or more CG occasions counted as invalid. In an embodiment, the UCI indicates the index of a CG UL occasion, and is to be released one or more occasions after the indicated CG occasion.

[0070] In an embodiment, the UCI indicates that a CG occasion is to be released regardless of whether the CG occasion is valid or invalid. In an embodiment, the UCI indicates that there are no released CG PUSCH occasions. In an embodiment, the UCI is composed of X bits (X is an integer), and X represents the number of unused CG PUSCH occasions. In this sense, if the number of CG PUSCH occasions in a period is 2, (X-1) +1~2 X Assume that:

[0071] Case 4: In an embodiment, the UE may determine that the UCI resource is valid based on the following rules:

[0072] If the UE is not provided with tdd-UL-DL-ConfigurationCommon, the UCI resource is valid if the occasion does not collide with the SS / PBCH block in the PUSCH slot, and the UCI resource is at least N symbols after the nearest SS / PBCH block. gap It starts with the symbol.

[0073] If the UE is provided with tdd-UL-DL-ConfigurationCommon, the UCI resource is valid if the occasion is within the duration of a UL symbol, and the UCI resource is at least N symbols after the nearest downlink symbol. gap symbols and at least N symbols after the nearest SS / PBCH block symbol gap It starts with the symbol.

[0074] [Example 2] Case 1: In an embodiment, if there are multiple CG occasions during a single CG configuration, the UE may determine one or more invalid symbols for CG PUSCH transmission as follows:

[0075] In an embodiment, the UE may determine one or more symbols designated as downlink resources as one or more invalid symbols, for example, Symbols designated as downlink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated shall be considered invalid symbols, The symbols indicated as resources of the SS / PBCH block are considered invalid symbols, and / or Symbols configured to receive PDCCH, PDSCH or CSI-RS in the reference cell are considered invalid symbols.

[0076] In an embodiment, the time gap between a UL symbol and a previous DL symbol (e.g., an SSB symbol) may be less than N_gap symbols, where N_gap can be determined by UE processing capabilities (e.g., by determining N_gap symbols (with a predetermined subcarrier spacing) for a normal XR UE device).

[0077] Case 2: In an embodiment, for XR-specific scenarios, the signaling indicates that certain CG occasions are invalid. Some examples are provided below.

[0078] In some embodiments, the deactivation signaling indicates that multiple CG occasions during an activation period (e.g., a PDCCH monitoring period) are disabled. In some embodiments, the deactivation signaling reconfigures CG PUSCH occasions during the activation period. In some embodiments, the deactivation signaling may not be activated outside of a certain time period.

[0079] In an embodiment, a CG occasion may not be deactivated by deactivation signaling, but some or all of the CG resources may be considered invalid when the UE receives an UL grant, where the UL grant is configured to be used for scheduling resources.

[0080] In one embodiment, for a plurality of UEs, the UEs can receive common signaling indicating that the CG occasion is disabled. The common signaling is sent to the plurality of UEs, instructing each UE whether the CG occasion is disabled. In another embodiment, the common signaling reconfigures the CG PUSCH occasion for the plurality of UEs.

[0081] In an embodiment, the DCI may indicate that the corresponding symbol is an invalid symbol.

[0082] Case 3: In an embodiment, for a CG PUSCH in a period, if a dynamic SFI is not configured and UL data in a CG UL resource collides with a semi-static DL symbol, the UL data is not transmitted.

[0083] In an embodiment, for a CG PUSCH within a period, if a dynamic SFI is configured and received and UL data in the CG UL resource collides with a dynamic DL or flexible symbol, the UL data may not be transmitted. In an embodiment, if UL data in the CG UL resource collides with a dynamic DL and / or flexible symbol, the UE may feed back assistance information (e.g., resource request information requesting new resources) to the gNB.

[0084] In an embodiment, for a CG PUSCH in a period, if a dynamic SFI is not configured and received, and UL data in a CG UL resource collides with semi-static DL and / or flexible symbols, no UL data is transmitted.
