The CU-DU structure can split the protocol layers of the access network device, and some of the protocol layers can be controlled by the CU, and the rest or all of the protocol layers can be distributed in the DU and controlled by the CU, but is not limited thereto.

[0140] In some embodiments, the core network device can be one device including the first network element, or can be multiple devices or device groups each including the first network element. The network element can be virtual or physical. The core network may, for example, include at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

Further, a plurality of systems can be combined (for example, combination of LTE and NR).

[0144] To improve UL coverage and throughput, subband full duplex (SBFD) will be studied in the duplex enhancement project. Specifically, a carrier component (CC) is divided into multiple subbands (SBs) in the frequency domain on the downlink (DL) or flexible (F) symbols. Multiple SBs, including one uplink (UL) SB and at least one DL SB, allow the base station to transmit DL signals in the DL SB and receive UL signals in the UL SB at the same time. The DL symbol or the F symbol is configured by the time division duplex uplink-downlink common configuration (TDD-UL-DL-ConfigCommon) or the time division duplex uplink-downlink dedicated configuration (TDD-UL-DL-ConfigDedicated) or the down control information (DCI) 2-0 as a DL or F symbol. A symbol that simultaneously contains a DL SB and a UL SB in the frequency domain can be referred to as an SBFD symbol. Similarly, a time slot that contains at least one SBFD symbol in multiple symbols can be referred to as an SBFD time slot. As shown in FIG. 1B, time slot #0 is a DL time slot containing 14 DL symbols, time slots #1-3 are SBFD time slots each containing 14 SBFD symbols, and time slot #4 is a UL time slot containing 14 UL symbols. There can also be a guard band (GB) between the DL SB and the UL SB to reduce interference between the DL signal in the DL SB and the UL signal in the UL SB by frequency domain isolation.

[0145] In a subband full duplex (SBFD) symbol, the GB and the DL SB are not available for UL transmission, and the UL SB is available for UL transmission. In an SBFD symbol, the frequency domain range available for UL transmission can be referred to as the UL available frequency domain range, and the frequency domain range unavailable for UL transmission can be referred to as the UL unavailable frequency domain range. According to the above analysis, the UL frequency domain range of the non-SBFD symbol and the SBFD symbol is different. The UL available frequency domain range is the UL frequency domain range on the CC. In an SBFD symbol, the UL available frequency domain range on the UL BWP refers to the frequency domain range overlapping the UL available frequency domain range on the CC. Unless otherwise specified, the UL available frequency domain range in the following refers to the UL available frequency domain range on the BWP.

[0146] Between the DL subband and the UL subband, there can also be a GB (guard band) to isolate the DL subband from the UL subband in the frequency domain to reduce interference between the DL signal in the DL subband and the UL signal in the UL subband.

[0147] In the SBFD symbol, the frequency domain range available for UL transmission can be discontinuous, including the following two cases: the GB and the DL subband are not available for UL transmission, and the UL subband is available for UL transmission; the DL subband is not available for UL transmission, and the UL subband and the GB are available for UL transmission.

[0148] The frequency domain range available for UL transmission in the SBFD symbol can be referred to as the UL frequency domain range, and the frequency domain range not available for UL transmission in the SBFD symbol can be referred to as outside the UL frequency domain range. As can be seen from the above, the UL frequency domain range of the non-SBFD symbol and the SBFD symbol is different. The UL frequency domain range is the UL frequency domain range on the CC. In the SBFD symbol, the UL frequency domain range on the UL BWP refers to the frequency domain range overlapping the UL frequency domain range on the CC. Unless otherwise specified, the UL frequency domain range in the following refers to the UL frequency domain range on the BWP.

[0149] When the UE is in an idle state, the UE measures the received signal strength and other information of the SSB beam when initially accessing a cell, and selects the optimal SSB beam. In the direction of the optimal SSB beam, the UE transmits a PRACH signal in a valid random access channel occasion (RO) to perform random access. A valid RO refers to an RO that is determined to be valid according to the criteria in the protocol among the configured ROs. In addition, in other states, the UE can also transmit a PRACH signal in a valid RO to perform random access. Random access includes contention-based random access (CBRA) and contention-free random access (CFRA), where there are multiple UEs using the same preamble sequence in CBRA, i.e., the PRACH signals of 2 UEs collide, which can cause random access to fail.

[0150] Random access can also be divided into 4-step random access and 2-step random access according to the number of steps in the random access (RA) process. In step 1 of 2-step random access, the UE transmits MsgA-PRACH in a valid RO and transmits MsgA-PUSCH in a valid PUSCH occasion (PO).

[0151] In SBFD symbols, UEs can transmit uplink signals on UL SB. Therefore, configuring PO in SBFD symbols can increase the number of POs compared to configuring PO in UL or F symbols only. SBFD-aware UEs can configure PO in SBFD symbols for random access, reduce access latency, and reduce the probability of MsgA-PRACH signal collision between different UEs in CBRA (Contention Based Random Access). As shown in FIG. 1C, POs configured in SBFD symbols can be referred to as additional valid POs, and valid POs in UL or F symbols can be referred to as legacy valid POs. In FIG. 1C, time units #0, #1, #2, #3, #5, #6, #7, and #8 are SBFD time units. Time units #4 and #9 are UL time units. Therefore, POs set in SBFD time units #0, #1, #2, #3, #5, #6, #7, and #8 are additional valid POs that increase PO capacity, and POs set in UL time units #4 and #9 are legacy valid POs.

[0152] In some embodiments, the time domain configuration can be as follows: msgA-PUSCH-TimeDomainOffset: offset between PO and PRACH slot (including valid RO), using the SCS (Subcarrier Spacing) of the active UL BWP, each PRACH slot (including valid RO) determines the slot where the PO is located, respectively, to determine the starting slot of the PO.

[0153] nrofSlotsMsgA-PUSCH: the number of consecutive slots containing 1 or more POs (PUSCH occasions), and the symbol position of the PO in each slot is the same. nrofMsgA-PO-PerSlot: the number of POs contained in 1 slot. guardPeriodMsgA-PUSCH: when 1 slot contains multiple POs in the time domain, the interval between POs is guardPeriod symbol length.

[0154] In some embodiments, the frequency domain configuration can be as follows: if Interlaced PUSCH is configured, the frequency domain range can be determined by the following parameters: interlaceIndexFirstPO-MsgA-PUSCH indicates the first Interlace index; nrofInterlacesPerMsgA-PO indicates the number of Interlaces contained in one PO; nrofMsgA-PO-FDM: the number of frequency division multiplexing of POs.

[0155] One Interlace can involve one or more reference common resource blocks (CRBs). If Interlaced PUSCH is not configured, the frequency domain range can be determined by the following parameters: frequencyStartMsgA-PUSCH: the offset of the frequency domain starting position of PO relative to PRB0 (starting PRB) of the UL BWP; nrofPRBs-PerMsgA-PO: the number of RBs of PO; nrofMsgA-PO-FDM: the number of POs frequency division multiplexed in the same time domain position; guardBandMsgA-PUSCH: the frequency domain interval between adjacent POs in the same time domain position; if Interlaced PUSCH is configured, guardBandMsgA-PUSCH is 0; hopping; msgA-IntraSlotFrequencyHopping: whether PO is allowed to hop within a slot; msgA-HoppingBits: the frequency offset between the first hop (1st hop) and the second hop (2nd hop) of frequency hopping can be determined in combination with msgA-HoppingBits and Table 1, where msgA-HoppingBits indicates the number of hopping bits in the table. FIG. ID shows a PO configuration parameter. For example, the PO configuration parameter can include: frequencyStartMsgA-PUSCH, which is used to indicate the offset between the PUSCH slot and the PRACH slot. Table 1 is an explanation of the UL BWP, UL sub-band, and hopping related parameters. st hop) and the second hop (2nd hop) of frequency hopping can be determined in combination with msgA-HoppingBits and Table 1, where msgA-HoppingBits indicates the number of hopping bits in the table. FIG. ID shows a PO configuration parameter. For example, the PO configuration parameter can include: frequencyStartMsgA-PUSCH, which is used to indicate the offset between the PUSCH slot and the PRACH slot. Table 1 is an explanation of the UL BWP, UL sub-band, and hopping related parameters.

[0156] Table 1

[0157] An example of Interlace containing CRB can be shown in FIG. 1E and FIG. 1F. Common Resource Block (CRB) is divided into M Interlaces. Each Interlace contains CRB within BWP#i: Overlap of BWP#i and Interlace. An example is as follows: CRB contains CRB#0-79, divided into 5 Interlaces, BWP contains CRB#4-72, then each Interlace contains CRB within BWP is: Interlace#0: 5, 10, 15, 20, …, 70, Interlace#1: 6, 11, 16, 21, …, 71, Interlace#2: 7, 12, 17, 22, …, 72, Interlace#3: 8, 13, 18, 23, …, 68, Interlace#4: 4, 9, 14, 19, 24, …, 69.

[0158] In the above configuration mode, as shown in FIG. 1G, when PUSCH is not configured with Interlace, if there is only one frequencyStartMsgA-PUSCH parameter to configure the starting position of PO. In order to ensure that PO is within the UL sub-band on the SBFD symbol, PO needs to be configured within the UL sub-band, which will cause the fragmentation of the UL available resources on the non-SBFD symbol. In order to ensure that the resources on the non-SBFD symbol are not fragmented, PO can be configured at the edge of the UL BWP, which may cause PO to be outside the UL sub-band on the SBFD symbol, resulting in PO being unable to be used. When PUSCH is not configured with Interlace, on the SBFD and non-SBFD symbols, the starting RB index of PO is determined according to the parameter frequencyStartMsgA-PUSCH, which may cause the following problems:

[0159] The starting frequency domain position of PO on the SBFD symbol does not consider the frequency domain range of UL transmission on the SBFD symbol, resulting in PO on the SBFD symbol being on the DL sub-band and being unable to be used. In view of this, FIG. 2 is an interaction schematic diagram of a PO determination method according to an example embodiment. As shown in FIG. 2, the embodiment of the present disclosure relates to a PO determination method for a communication system 100, and the method comprises:

[0161] In some embodiments, the network device can be an access network device, and exemplary access network devices can include, but are not limited to, eNB and / or gNB, etc.

[0162] In some embodiments, the network device sends a radio resource control (RRC) message, a media access control (MAC) layer message, or a physical layer message to the UE. The RRC message, the MAC layer message, or the physical layer message can include the PO configuration information described above.

[0163] In some embodiments, the PO configuration information can be used by the UE to determine the resource location of one or more POs. Exemplarily, the PO configuration information can include, but is not limited to, at least one of the following:

[0165] nrofSlotsMsgA-PUSCH: number of consecutive slots containing one or more POs, each slot has the same symbol location for the POs;

[0166] nrofMsgA-PO-PerSlot: number of POs contained in one slot.

[0167] GuardPeriodMsgA-PUSCH: if one slot contains multiple POs in time domain, the guard period between the POs is guardPeriod symbols long.

[0168] If PUSCH is configured with interlace, the PO configuration information includes at least one of the following: interlaceIndexFirstPO-MsgA-PUSCH indicates the first interlace index; nrofInterlacesPerMsgA-PO indicates the number of interlaces contained in one PO; nrofMsgA-PO-FDM: number of FDMed POs.

[0169] If PUSCH is configured with interlace, the PO configuration information includes at least one of the following: frequencyStartMsgA-PUSCH: frequency domain starting position of the PO, offset value relative to PRB0 of the CC; nrofPRBs-PerMsgA-PO: number of RBs of the PO; nrofMsgA-PO-FDM: number of FDMed POs at the same time domain location; guardBandMsgA-PUSCH: frequency domain interval between adjacent POs at the same time domain location.

[0170] Of course, the above is only an example of the PO configuration information, and the specific implementation is not limited to the above example.

The second parameter is related to the staggering of PUSCH.

[0173] In some embodiments, the first parameter indicates the starting RB of the first PO on the non-SBFD time unit of the UL BWP, but the value indicated by the first parameter can be used for the frequency domain position determination of the PO in the SBFD time unit and / or the non-SBFD time unit.

[0174] It is worth noting that the non-SBFD time unit here can be any SBFD time unit other than the SBFD time unit. Specifically, the non-SBFD time unit can include a UL time unit not configured as a SBFD time unit, a DL time unit not configured as a SBFD time unit, and / or a F time unit not configured as a SBFD time unit.

[0175] In some embodiments, the first parameter includes at least one of the following:

[0184] In some embodiments, in the case that the network device does not send TDD-UL-DL-ConfigCommon and / or DD-UL-DL-ConfigDedicated information elements (IEs), the time units available to the UE are not configured by the TDD-UL-DL-ConfigCommon IE and / or the DD-UL-DL-ConfigDedicated IE.

[0185] In some embodiments, the first type of SBFD time unit is configured with a PO, and the second type of SBFD time unit is not configured with a PO.

[0186] In some embodiments, the first type of UE has the capability to identify SBFD time units; the second type of UE does not have the capability to identify SBFD time units.

[0187] In some embodiments, the first parameter indicates the starting RB of the first PO on the SBFD time unit of the UL BWP.

Illustratively, the first parameter can include, but is not limited to, frequencyStartMsg-A-PUSCH-r16 that is newly defined or reinterpreted.

[0188] In some embodiments, the first parameter can or can not be carried in the PO configuration information. For example, the first parameter can be carried in any other downlink message, for example, the first parameter can be configured in a system message, an RRC message, a MAC layer message, or a physical layer message.

[0357] The specific method is the UE side method 2, which is not described here.

[0358] Embodiments

[0359] Embodiment 1 Method UE side: PUSCH is not configured interlaced, SBFD aware UE determines the frequency domain position of each PO on SBFD symbol in PO Config by the following method.

[0360] On SBFD symbol, UL subband can be used for UL transmission, if PO is within UL subband, it can be used to send MsgA-PUSCH signal, otherwise, PO cannot be used to send MsgA-PUSCH signal.

[0361] One example is as follows: on SBFD symbol, frequencyStartMsgA-PUSCH is understood as the offset of the first RB of the UL BWP, that is, frequencyStartMsgA-PUSCH, which may cause frequencyStartMsgA-PUSCH to be too large or too small, resulting in the problem that PO in SBFD is outside the UL subband, resulting in PO being unavailable, which can be shown in FIG. 5A.

[0362] On SBFD symbol, if frequencyStartMsgA-PUSCH is understood as the offset value of the first RB of the UL subband, frequencyStartMsgA-PUSCH may also be too large, resulting in the problem that PO in SBFD is outside the UL subband, which can be shown in FIG. 5B.

[0363] To avoid the above problems, methods 1-1 to 1-5 can be used.

[0364] Method 1: PUSCH is not configured interlaced, UE determines the frequency domain position of each PO on SBFD symbol according to the starting RB in UL subband and / or parameter 1

[0365] One example of method 1-1 is as follows:

[0366] The protocol defaults, high layer configurations or other parameters determine that the value of A is 2, which can avoid the value of frequencyStartMsgA-PUSCH being too large, resulting in the problem that PO in SBFD is outside the UL subband and further resulting in PO on SBFD symbol being unavailable. If this method is used, the PO configuration effect can be as shown in FIG. 5C.

[0367] One example of method 1-2 is as follows:

[0368] B is determined by protocol default, higher layer configuration or other parameters The value of frequencyStartMsgA-PUSCH mod B can be guaranteed to be less than That is, the starting position of the first PO can be guaranteed to be within the UL sub-band.

[0369] B is determined by protocol default, higher layer configuration or other parameters The value of frequencyStartMsgA-PUSCH mod B can be guaranteed to be less than That is, the frequency domain position of the first PO can be guaranteed to be within the UL sub-band, as shown in FIG. 5D.

[0370] An example of mode 1-3 is as follows: the starting RB of the first PO of FDM on the SBFD symbol is C is determined by protocol default, higher layer configuration or other parameters, and the value is 0, so that the starting RB of the first PO can be guaranteed to be the first RB of the UL sub-band, as shown in FIG. 5E. In this case, frequencyStartMsgA-PUSCH is not referred to when determining the starting RB of the first PO within the SBFD symbol.

[0371] An example of mode 1-4 is as follows: frequencyStartMsgA-PUSCH on non-SBFD symbols can be reasonably configured to enable POs on SBFD symbols to be within the UL sub-band as much as possible.

[0372] frequencyStartMsgA-PUSCH-SBFD on SBFD symbols can be reasonably configured to enable POs on SBFD symbols to be within the UL sub-band as much as possible.

[0373] An example of mode 1-5 is as follows: E is determined by protocol default, higher layer configuration or other parameters The value of (frequencyStartMsgA-PUSCH + (n-1)*nrofPRBs-PerMsgA-PO + (n-1)*guardBandMsgA-PUSCH) mod B can be guaranteed to be less than That is, the starting position of each PO on the SBFD symbol can be guaranteed to be within the UL sub-band.

[0374] E is determined by protocol default, higher layer configuration or other parameters The value of (frequencyStartMsgA-PUSCH + (n-1)*nrofPRBs-PerMsgA-PO + (n-1)*guardBandMsgA-PUSCH) mod B can be guaranteed to be less than That is, the frequency domain position of each PO on the SBFD symbol is ensured to be within the UL sub-band.

[0375] In the manner 1-5, there may be a case that the frequency domain positions of multiple POs overlap on the SBFD symbol, in which case the PO with a larger PO index can be considered as an invalid PO.

[0376] Embodiment 2 - Manner 2

[0377] UE side: Interlaced PUSCH is configured, and the SBFD aware UE determines the frequency domain position of each PO on the SBFD symbol in the PO Config through the following method. The PO Config can be an IE carrying PO configuration information.

[0378] Manner 2: Interlaced PUSCH is configured, and the UE determines the frequency domain position of each PO on the SBFD symbol according to the frequency domain range in the UL sub-band and / or parameter 2

[0379] In the manner 2, the number of Interlaces contained by each PO is determined according to the starting Interlace index, the number of Interlaces contained by one PO, and the number of PO FDMs on the SBFD symbol, and the Interlace index contained by each PO can be determined

[0380] In the manner 2-1, the starting Interlace index, the number of Interlaces contained by one PO, and the number of PO FDMs on the SBFD symbol are completely different from the configuration on the non-SBFD symbol; in the manner 2-2, at least one of the starting Interlace index, the number of Interlaces contained by one PO, and the number of PO FDMs on the SBFD symbol is different from the non-SBFD.

[0381] An example is as follows: the RB set contained by each Interlace in the frequency domain range of the UL sub-band is determined

[0382] An example is as follows: as shown in FIG. 1E, the CRBs contain CRB#0-79, which are divided into 5 Interlaces, and the UL sub-band contains CRB#12-70, so that the CRBs contained by each Interlace in the UL sub-band are: Interlace#0: 15, 20, …, 70, Interlace#1: 16, 21, …, 71, Interlace#2: 12, 17, 22, …, 72, Interlace#3: 13, 18, 23, …, 68, Interlace#4: 14, 19, 24, …, 69.

[0383] The interleaving corresponding to the UL subband can be as shown in FIG. 1F. In combination with the Interlace included in each PO and the RB set included in each Interlace, the frequency domain position of each PO is determined.
