[0048] Fig. 1A illustrates an example network environment 100A in which example embodiments of the present disclosure may be implemented. The environment 100A, which may be a part of a communication network, comprises terminal devices 121-126, network devices 111-113. As illustrated in Fig. 1A, terminal devices 121 and terminal devices 122 may in the coverage of network device 111 (cell 131) , terminal devices 123 and terminal devices 124 may in the coverage of network device 112 (cell 132) , and terminal devices 123 and terminal devices 124 may in the coverage of network device 112 (cell 133) . The cell 132 and the cell 133 are the neighbor cells of the cell 131.
[0049] It is to be understood that the number of devices is only for the purpose of illustration without suggesting any limitations. The environment 100A may include any suitable number of terminal devices and network devices adapted for implementing embodiments of the present disclosure.
[0050] Communications in the communication environment 100A may be implemented according to any proper communication protocol (s) , comprising, but not limited to, cellular communication protocols of the first generation (1G) , the second generation (2G) , the third generation (3G) , the fourth generation (4G) and the fifth generation (5G) and on the like, wireless local network communication protocols such as Institute for Electrical and Electronics Engineers (IEEE) 802.11 and the like, and / or any other protocols currently known or to be developed in the future. Moreover, the communication may utilize any proper wireless communication technology, comprising but not limited to: code division multiple access (CDMA) , frequency division multiple access (FDMA) , time division multiple access (TDMA) , frequency division duplex (FDD) , time division duplex (TDD) , multiple-input multiple-output (MIMO) , orthogonal frequency division multiple (OFDM) , discrete Fourier transform spread OFDM (DFT-s-OFDM) and / or any other technologies currently known or to be developed in the future.
[0051] 3GPP 5G NR currently supports two duplexing modes: FDD for paired bands and TDD for unpaired bands. In TDD, uplink and downlink phases are separated in time domain. This may create unnecessary latency, possibly reduce coverage and capacity depending on the considered TDD radio frame configuration. In TDD deployments, the situation is further exacerbated by the fact that the scheduling offers lower dynamism, i.e., the slot structure is fixed and does not change very often in practice. Moreover, 5G NR TDD deployments focuses on ensuring enough capacity for the demanding downlink traffic. This may result in rather limited time duration for the uplink in TDD.
[0052] Motivated by this, 3GPP has done a study item in Rel-18 and confirmed a work item in Rel-19, on the evolution of duplexing operation in NR that addresses the challenges above. One of the objectives is to allow the gNB to do simultaneous DL transmission and UL reception on different physical resource blocks (PRBs) / subbands within an unpaired wideband NR carrier. In some embodiments of the present disclosure, we refer to this as subband non-overlapping full duplex (SBFD) . In other sources, this duplexing scheme is also referred to as cross-division duplexing (xDD) scheme or Flexible Duplexing (FDU) .
[0053] Fig. 1B illustrates an example of SBFD and non-SBFD slots according to some embodiments of the present disclosure. From the above description of SBFD operation, it can be observed that there are two slot types for both DL and UL transmissions as shown in Fig. B:
[0054] ○ SBFD slots, during which the non-overlapping DL subband (s) which corresponds to DL resource 150-1 and UL subband (s) which corresponds to UL resource 150-2 both exist, and
[0055] ○ Non-SBFD slots, during which the entire band is used for either DL or UL (i.e., legacy / full DL / UL slots) .
[0056] In SBFD slots, a guard band which comprises guard resource 150-3 is expected to be placed between DL and UL resource blocks (RBs) . This provides better isolation between UL and DL transmissions and is expected to be essential for reducing the impact of the self-interference (due to gNB’s own DL transmissions and the gNB’s own UL reception) as well as cross-link interference (CLI) between UE to UE links, and gNB to gNB links.
[0057] Fig. 1C illustrates an example of co-channel cross-link interference types in SBFD deployment according to some embodiments of the present disclosure. SBFD may introduce new types of CLI, namely co-channel inter-subband CLI from non-overlapping frequency resources. As shown in Fig. 1C, the cell 132 and the cell 133 are the neighbor cells of the cell 131. The cell 132 has the same frequency domain partitioning with the cell 131. The cell 131 has the different frequency domain partitioning with the cell 133. Thus in the scenario of the Sub-band Non-overlapping frequency resources full duplex for same frequency domain partitioning (for example, the cell 132 has the same frequency domain partitioning with the cell 131) , the cross-link interference can be better classified depending on the source of the interference as:
[0058] (1) gNB self-interference (140-1) .
[0059] (2) intra-cell UE-to-UE co-channel inter-subband CLI (140-2) .
[0060] (3) inter-cell UE-to-UE co-channel inter-subband CLI (140-3) .
[0061] (4) gNB-to-gNB co-channel inter-subband CLI (140-4) .
[0062] Besides these new CLI types, in case of different frequency domain partitioning in neighbor cells (for example, the cell 132 has the different frequency domain partitioning with the cell 133) , the system may also suffer from co-channel CLI from transmissions on overlapping frequency resources:
[0063] (5) gNB-to-gNB inter-cell co-channel CLI from overlapping frequency resources (140-5) .
[0064] (6) UE-to-UE inter-cell co-channel CLI from overlapping frequency resources (140-6) .
[0065] Several techniques were proposed for handling gNB-to-gNB CLI (such as 140-5 and / or 140-4) , among which UL resource muting was proposed to ensure that the gNB-to-gNB CLI measurements and / or gNB-to-gNB channel measurements at the victim gNB are free from UL signals. Two methods had been discussed regarding the UL muting, transparent and non-transparent.
[0066] Transparent muting relies on gNB scheduling without specific indication to UE, while non-transparent method is to perform RE-level muting by gNB indication for a specific muting pattern to apply for its UL transmission.
[0067] Specifically, for UL resource muting, indication / determination of UL resource muting for Physical Uplink Shared Channel (PUSCH) based on semi-static configuration, assuming comb-2 for both DFT-S-OFDM and CP-OFDM in each allocated Physical Resource Block (PRB) and up to 2 symbols in time domain. It is to be noted that there is no new DCI field / Media Access Control Control Element (MAC CE) is introduced. Also, UL resource muting for PUSCH comprise the uplink control information (UCI) determination in symbols with muted REs (resource element) .
[0068] Uplink control information (UCI) message may consist of at least one of the following information:
[0069] (1) Hybrid automatic repeat request acknowledgement (HARQ-ACK)
[0070] (2) Channel state information (CSI) , which consist of CSI part 1 and CSI part 2. The former has fixed payload size and is used to identify number of information bits in the latter. Therefore, CSI part 1 must be transmitted completely before the transmission of CSI part 2.
[0071] (3) Scheduling request (SR)
[0072] The UCI message can be encoded and transmitted through PUCCH or multiplexed on PUSCH. Only HARQ-ACK and CSI are multiplexed on PUSCH. SR is not multiplexed on PUSCH since PUSCH is able to convey a buffer status report (BSR) , which contains more detailed information about UE’s uplink buffer status compared to the SR.
[0073] For calculation of the number of coded modulation symbols per layer for each UCI type, before the step of mapping the coded modulation symbols to the REs, there is a step of calculating the number of coded modulation symbols per layer for each UCI type. A higher-layer parameter known as β parameter (or beta offset) is used by UE to determine the amount of resource within PUSCH to be dedicated for the UCI in case of multiplexing (realized in the number of coded modulation symbols per layer) .
[0074] In some examples, for determining the number of coded bits dedicated to UCI and how to account for the muted REs due to uplink muting, there exists an approach to use 2 different beta offsets, one for the symbols colliding with the UL muting pattern and one for the symbols not colliding with the UL muting pattern.
[0075] Fig. 1D illustrates an example of UL resource muting on PUSCH. It is assumed that UL resource muting for PUSCH based on semi-static configuration and comb-2 for both DFT-S-OFDM and CP-OFDM in each allocated PRB and up to 2 symbols in time domain.
[0076] Fig. 1D shows the scenario that is considered in some embodiments of the present disclosure, in which the UL muting pattern is configured to happen periodically. When the UL muting is expected, and if there is a PUSCH transmission 160-1 that overlaps with the UL muting pattern, data will be rate-matched around the muted resources (for example, muted resource 160-2) . The PUSCH transmission 160-1 may comprise remaining resource for data, reference signals, and UCI (160-3) . However, there might be cases where the gNB prefers to prioritize the UL transmission rather than the UL muting (and subsequently, the gNB-to-gNB CLI (such as 140-4 and 140-5) / channel measurements) . This might be the case, if the gNB wants to maximize the number of REs dedicated to the PUSCH. Note that comb-2 muting is already agreed, i.e. 1 out of 2 subcarriers are muted in a given symbol, and it might result in large spectral efficiency losses (This will be described later with reference to Fig. 1E) .
[0077] Fig. 1E illustrates an example of spectral efficiency losses due to UL muting for different PUSCH duration and 1 or 2 OFDM symbol muting.
[0078] The curve 170-1 represents one OFDM symbol muting, and the curve 170-2 represents two OFDM symbols muting. It can be seen from the Fig. 1E, both one OFDM symbol muting and two OFDM symbols muting may result in large spectral efficiency losses. Specially, if the number of allocated symbols for the PUSCH is low, the spectral efficiency losses is extremely high.
[0079] To solve this problem, some embodiments of the present disclosure propose a method for the gNB to dynamically signal the UE the indication of the muting pattern (for example, dynamic indication of uplink muting applicability) . In other words, it proposes approach of for the UL grant to indicate the UE that the pre-configured (and periodic) UL muting should not be applied for the scheduled PUSCH. In some scenarios, the gNB may provide UE with a set of rules to indicate the UL muting should be applied. For consideration of the spectral efficiency losses, gNB may utilize the DCI with dynamic indication to stop applying the UL muting. This dynamic indication is useful in situations where the gNB prefers to prioritize the UL reception compared to measure the gNB-to-gNB CLI (such as 140-5 and / or 140-4) and / or estimate the gNB-to-gNB channel.
[0080] Reference is now made to Fig. 2, which shows a process 200 for dynamic indication of uplink muting according to an embodiment of the present disclosure. For the purpose of discussion, the process 200 will be described with reference to Fig. 1A and Fig. 1C. Although Figure 2 shows the interaction between terminal device 121 and network device 111, it can be understood that process 200 can also be performed by, for example, terminal device 122 and network device 111, terminal device 123 and network device 112, and so on.
[0081] The terminal device 121 may receive 210 DCI for an UL transmission overlapping with an UL resource muting pattern from the network device 111. The DCI comprises indication information related to UL muting for the UL transmission. The details of the indication information will be described later with reference to Fig. 4-Fig. 7.
[0082] The terminal device 121 may determine 215 whether to perform the UL muting for the UL transmission based on the indication information. The determination details will be described later with reference to Fig. 4-Fig. 7.
[0083] The terminal device 121 may perform 220 the UL transmission related to the PUSCH to the network device 111.
[0084] In this way, the network device may utilize the dynamic indication of UL muting pattern, to cause more Resource Elements (REs) are dedicated to PUSCH transmissions. This may reduce the spectral efficiency losses and increase the efficiency of the UL transmissions.
[0085] Reference is now made to Fig. 3, which shows a process 300 for dynamic indication of uplink muting according to another embodiment of the present disclosure. For the purpose of discussion, the process 300 will be described with reference to Fig. 1A and Fig. 1C. Although Figure 3 shows the interaction between terminal device 121 and network device 111, it can be understood that process 300 can also be performed by, for example, terminal device 122 and network device 111, terminal device 123 and network device 112, and so on.
[0086] Before receiving the DCI with indication information, the terminal device 121 may receive 305 a SBFD configuration, an UL resource muting pattern configuration and a PUSCH configuration from the network device 111. The PUSCH configuration (for example, PUSCH RRC configuration) . The PUSCH configuration may comprise the beta offset field.
[0087] There are 2 different UE behaviors regarding the beta offset supported in the agreement. Specifically, the UE can be configured as semi-static and dynamic as part of the PUSCH configuration which may related to the beta offset (betaOffsets) field. The PUSCH configuration may be defined in TS 38.331 as follow:
[0088] The terminal device 121 may receive 310 a DCI for an UL transmission (PUSCH) that overlaps with UL resource muting pattern. The DCI includes an indication information of whether the UL muting should be applied or not.
[0089] The terminal device 121 may determine 315 whether the UL muting should be applied or not for the given PUSCH according to the information in the DCI. Also the terminal device 121 may map the data (and UCI if any) bits to the available resources according to the DCI.
[0090] Then, the terminal device 121 may perform 320 the UL transmission (PUSCH) to the network device 111.
[0091] There are two options for the indication information.
[0092] Option 1: The indication information may comprise a new field or additional field for a reused DCI.
[0093] Option 2: The indication information may comprise a reused field (for example, an existing field) in the DCI.
[0094] Compared to option 1, scheme of the option 2 may not introduce new DCI field, which is more suitable for the 3gpp agreement. It is still unsure whether that note (No new DCI field / MAC CE is introduced) on the agreement shown above applies only to the activation / configuration of the UL muting or whether it applies as well to the deactivation (as proposed in Option 1) . But both of the option 1 and option 2 may implement the dynamic indication of uplink muting.
[0095] In the case of the indication information may comprise a reused field (for example, an existing field) . Reference is now made to Fig. 4, which shows a process 400 for dynamic indication of uplink muting according to another embodiment of the present disclosure. For the purpose of discussion, the process 400 will be described with reference to Fig. 1A and Fig. 1C. Although Figure 4 shows the interaction between terminal device 121 and network device 111, it can be understood that process 400 can also be performed by, for example, terminal device 122 and network device 111, terminal device 123 and network device 112, and so on.
[0096] Before receiving the DCI with indication information which comprises the reused field (such as an existing field of the DCI) , the terminal device 121 may receive 405 a SBFD configuration, an UL resource muting pattern configuration and a PUSCH configuration from the network device 111. The PUSCH configuration (for example, PUSCH RRC configuration) may comprise a semi-static beta offset configuration. The PUSCH configuration may indicate semi-static beta offset.
[0097] After receiving the PUSCH configuration comprising a semi-static beta offset configuration, a SBFD configuration and UL resource muting pattern configuration from the network device 111, the terminal device 121 may be configured with a semi-static beta offset configuration and UL muting pattern. The terminal device 121 may always expect (and read) the beta offset indicator field in the DCI.
[0098] Then the terminal device 121 may receive 410 DCI for an UL transmission overlapping with an UL resource muting pattern from the network device 111. The DCI comprises a beta offset indicator field for indicating whether the UL muting is to be applied to the UL transmission.
[0099] The beta offset indicator field may comprise one bit. This bit may have two different values, for example, 1 or 0.
[0100] The terminal device 121 may determine 415 whether to perform the UL muting for the UL transmission based on the indication information (beta offset indicator) . As an example, the beta offset indicator may comprise one bit. The terminal device 121 may apply the UL muting when the beta offset indicator value is 1 and not apply the UL muting when the beta offset indicator is 0.
[0101] The beta offset indicator field may be defined in the DCI format 0_1. The DCI format 0_1 may be defined as follow:
[0102] It is to be understood that in some embodiments, the terminal device 121 may apply the UL muting when the beta offset indicator value is 0 and not apply the UL muting when the beta offset indicator value is 1.
[0103] The terminal device 121 may perform 420 the UL transmission. For example, the terminal device 121 may map the data (and UCI if any) bits to the available resources according to the DCI and perform the UL transmission (PUSCH) .
[0104] Reference is now made to Fig. 5, which shows a process 500 for dynamic indication of uplink muting according to another embodiment of the present disclosure. For the purpose of discussion, the process 500 will be described with reference to Fig. 1A and Fig. 1C. Although Figure 5 shows the interaction between terminal device 121 and network device 111, it can be understood that process 500 can also be performed by, for example, terminal device 122 and network device 111, terminal device 123 and network device 112, and so on.
[0105] Before receiving the DCI with indication information which comprises the reused field (such as an existing field of the DCI) , the terminal device 121 may receive 505 a SBFD configuration, an UL resource muting pattern configuration and a PUSCH configuration from the network device 111. The PUSCH configuration (for example, PUSCH RRC configuration) may comprise a dynamic beta offset configuration.
[0106] After receiving the PUSCH configuration comprising a dynamic beta offset configuration, a SBFD configuration and an UL resource muting pattern configuration from the network device 111, the terminal device 121 may be configured with a dynamic beta offset configuration and UL muting pattern. The terminal device 121 may expect (and read) the beta offset indicator field in the DCI scheduling the PUSCH.
[0107] Then the terminal device 121 may receive 510 DCI for an UL transmission overlapping with an UL resource muting pattern from the network device 111. The DCI comprises a beta offset indicator field for indicating whether the UL muting is to be applied to the UL transmission.
[0108] The beta offset indicator field may comprise a first beta offset indicator value and a second beta offset indicator value. The first part of a bit sequence in the DCI indicates the first beta offset indicator value. The second part of the bit sequence in the DCI indicates the second beta offset indicator value. The first beta offset indicator value and the second beta offset indicator value are included in a beta offset indicator field of the DCI.
[0109] In some embodiments, one of the first beta offset indicator value is applied based on a condition that a symbol of the UL transmission overlaps with the UL resource muting pattern, the other one of the first beta offset indicator value is applied based on a condition that a symbol of the UL transmission does not overlap with the UL resource muting pattern.
[0110] In some embodiments, the second beta offset indicator value is applied based on a condition that a symbol of the UL transmission overlaps with the UL resource muting pattern, and the other one of the first beta offset indicator value or the second beta offset indicator value is applied based on a condition that a symbol of the UL transmission does not overlap with the UL resource muting pattern.
[0111] The terminal device 121 may determine 515 whether to perform the UL muting for the UL transmission based on the indication information (beta offset indicator) . In some embodiments, the terminal device 121 may not apply the UL muting when the first beta offset indicator value is equal to the second beta offset indicator value (i.e., the terminal device 121 assumes that no muting is applied on the scheduled PUSCH) and may apply the UL muting when the first beta offset indicator value is different from the second beta offset indicator value (i.e., the terminal device 121 assumes that the UL muting is applied on the scheduled PUSCH) . In this way, the network device 111 may implicitly indicate the terminal device 121 to not apply the muting if the beta offset indicator value for the overlapping symbols is the same as for the non-overlapping symbols.
[0112] The terminal device 121 may perform 520 the UL transmission. For example, the terminal device 121 may map the data (and UCI if any) bits to the available resources according to the DCI and perform the UL transmission (PUSCH) .
[0113] Reference is now made to Fig. 6, which shows a process 600 for dynamic indication of uplink muting according to another embodiment of the present disclosure. For the purpose of discussion, the process 600 will be described with reference to Fig. 1A and Fig. 1C. Although Figure 6 shows the interaction between terminal device 121 and network device 111, it can be understood that process 600 can also be performed by, for example, terminal device 122 and network device 111, terminal device 123 and network device 112, and so on.
[0114] Before receiving the DCI with indication information which comprises the reused field (such as an existing field of the DCI) , the terminal device 121 may receive 605 a SBFD configuration, an UL resource muting pattern configuration and a PUSCH configuration from the network device 111. The PUSCH configuration (for example, PUSCH RRC configuration) may comprise a dynamic beta offset configuration. The dynamic beta offset configuration may indicate the dynamic beta offset.
[0115] After receiving the PUSCH configuration comprising a dynamic beta offset configuration, a SBFD configuration and an UL resource muting pattern configuration from the network device 111, the terminal device 121 may be configured with a dynamic beta offset configuration and UL muting pattern. The terminal device 121 may expect (and read) the beta offset indicator field in the DCI scheduling the PUSCH.
[0116] Then the terminal device 121 may receive 610 DCI for an UL transmission overlapping with an UL resource muting pattern from the network device 111. The DCI includes 2 beta offset indicator values for the overlapping and non-overlapping symbols
[0117] In some embodiments, the terminal device 121 may receive 2 beta offset indicator values to be applied to the overlapping UL / SBFD symbols and to the non-overlapping UL / SBFD symbols. If the UL muting pattern indicates that this symbol is to be muted, one symbol may be denote as overlapping. Otherwise, the symbol is defined a non-overlapping. The terminal device 121 may expect that the beta offset for the overlapping symbols is lower than the beta offset for the non-overlapping symbols in order to account for the reduced number of available REs due to muting.
[0118] For example, UE may receive 2 beta offset indicator values as part of the DCI. The bit sequence in the DCI is split to indicate the 2 beta offsets, for example, the LSB bits are used for the indication of the non-overlapping beta offset and the MSB bits are used for the indication of the overlapping beta offset. If the scheduled PUSCH is not overlapping with the UL muting, the UE interprets the beta offset indicator as legacy.
[0119] Alternatively, the size of the beta offset indicator field in the DCI may be increased to accommodate the larger number of bits, i.e., twice the size of the current field size. It is to be noted that current beta offset indicator field sizes are either 1 bit or 2 bits.
[0120] The terminal device 121 may determine 615 whether to perform the UL muting for the UL transmission based on the indication information (beta offset indicator) . In some embodiments, the terminal device 121 may not apply the UL muting when the indicated 2 beta offset indicators have same value (i.e., the terminal device 121 assumes that no muting is applied on the scheduled PUSCH) , and may apply the UL muting when the indicated 2 beta offset indicators have different value (i.e., the terminal device 121 assumes that the UL muting is applied on the scheduled PUSCH) . In this way, the network device 111 may implicitly indicate the terminal device 121 to not apply the muting if the beta offset indicator value for the overlapping symbols is the same as for the non-overlapping symbols.
[0121] The terminal device 121 may perform 620 the UL transmission. For example, the terminal device 121 may map the data (and UCI if any) bits to the available resources according to the DCI and perform the UL transmission (PUSCH) .
[0122] In the case of the indication information may comprise a new field or an additional field for a reused DCI, such as an existing DCI. Reference is now made to Fig. 7, which shows a process 700 for dynamic indication of uplink muting according to another embodiment of the present disclosure. For the purpose of discussion, the process 700 will be described with reference to Fig. 1A and Fig. 1C. Although Figure 7 shows the interaction between terminal device 121 and network device 111, it can be understood that process 700 can also be performed by, for example, terminal device 122 and network device 111, terminal device 123 and network device 112, and so on.
[0123] Before receiving the DCI with indication information which comprises the new field, the terminal device 121 may receive 705 a SBFD configuration, an UL resource muting pattern configuration and a PUSCH configuration from the network device 111.
[0124] Then the terminal device 121 may receive 710 DCI for an UL transmission overlapping with an UL resource muting pattern from the network device 111. The DCI comprises a new field for indicating whether the UL muting is to be applied to the UL transmission (e.g., skipULmutingIndicator) . This field may comprise one bit. The value of this bit may be 1 or 0. It can be understood that in some other embodiments, the new filed may have more than one bit.
[0125] The terminal device 121 may determine 715 whether to perform the UL muting for the UL transmission based on the indication information (new field) . As an example, the terminal device 121 may apply the UL muting when the new field value is 1 and not apply the UL muting when the new field is 0.
[0126] It is to be understood that in some embodiments, the terminal device 121 may apply the UL muting when the new field value is 0 and not apply the UL muting when the new field value is 1.
[0127] The terminal device 121 may perform 720 the UL transmission. For example, the terminal device 121 may map the data (and UCI if any) bits to the available resources according to the DCI and perform the UL transmission.
[0128] This is the most straightforward option and simply proposes that the terminal device will receive an indication in the DCI that schedules the PUSCH indicating whether or not the UE shall account for the UL muting in that slot (or set of slots for the case of configured-grant, TB over multiple slots, or repetitions) .
[0129] In some embodiments, the UL transmission in process 200-700 is performed in at least one SBFD slot or symbol. In some embodiments, the UL transmission in process 200-700 is performed in at least one dynamic Time-division Duplex (TDD) slot or symbol and therefore UL muting can also be used there to ensure that the UL signals do not interfere with the measurements of gNB-to-gNB CLI at the victim network device. It can be understood that when the UL transmission is performed in at least one dynamic TDD slot or symbol, the terminal device 121 may first receive the dynamic TDD configuration from the network device 111.
