The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0025] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) or other systems. The terms "system" and "network" in this application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than NR system applications, such as 6th generation (6G) systems. th Generation, 6G) communication system.

[0026] To facilitate understanding of the embodiments of this application, the following technical points are first introduced:

[0027] 1. Full-duplex (FD) mode.

[0028] Fifth-generation (5G) mobile communication systems have enhanced full duplex technologies to accommodate diverse scenarios and service requirements. Key 5G scenarios include enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine type communications (mMTC). These scenarios place high demands on system reliability, low latency, high bandwidth, and wide coverage.

[0029] In the New Radio (NR), configuring full-duplex operation can significantly improve the latency and coverage performance of the Time Division Duplexing (TDD) system.

[0030] 1.1. Subbands non-overlapping full duplex

[0031] Sub-band non-overlapping full-duplex can improve transmission delay and enhance coverage.

[0032] For a downlink (DL) slot (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), the network configures the DL bandwidth part (BWP) for (e.g., user equipment (UE)). For an uplink (UL) slot, the network configures the UL BWP for the UE. For example, slots 1 and 4.

[0033] For the full duplex scenario, there are the following examples, as shown in Figures 1 and 2.

[0034] Example 1: Configure DL BWP, that is, slot 1.

[0035] Example 2: Configure DL BWP and UL sub-band, namely slot 2.

[0036] A UL slot is configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated.

[0037] Example 3: Configure UL BWP, that is, slot 4.

[0038] Example 4: Configure UL BWP and DL sub-band, namely slot 5.

[0039] For SubBand Full Duplex (SBFD) operation, one SBFD subband consists of one resource block (RB) or a set of consecutive RBs with the same transmission direction.

[0040] A time unit (eg, slot or symbol) in which the base station operates using SBFD may be referred to as a SBFD time unit (eg, slot or symbol).

[0041] For Release 15 (Rel-15), the base station and UE can only send or receive at a time.

[0042] For Release 18 (Rel-18), the base station side is full-duplex, and the base station can send and receive at the same time, while the UE side can only use half-duplex mode, that is, it can only send or receive at a time.

[0043] For full-duplex on the UE side, the gNB and UE can transmit and receive simultaneously.

[0044] For full-duplex at the UE side, a larger guard band (GB) (larger than the GB of the base station FD) may be required to suppress self-interference.

[0045] For a communication device, simultaneous UL reception and DL transmission can cause self-interference. To ensure transmission in the interfered direction, the communication device needs to have self-interference cancellation capabilities, such as reserving a guard band between the receive and transmit bands. However, this reduces UE throughput.

[0046] In 5G and future 6G systems, both base stations and terminals may adopt full-duplex mode.

[0047] 2. Uplink power control:

[0048] In the design of new air interface systems, new features are being considered for uplink transmission, such as orthogonal frequency division multiplexing (OFDM)-based uplink transmission and a single-symbol uplink control channel. Uplink power control is also a key component, including the following key points:

[0049] i. There is no cell-specific reference signal similar to Long Term Evolution (LTE) for path loss estimation;

[0050] ii. Beam-based transmission / reception;

[0051] iii. Analog beamforming at the base station or terminal;

[0052] iv. Multi-beam or multi-stream transmission;

[0053] v. Multiple parameter sets (numerology);

[0054] vi. Information exchange between Transmission and Receiving Points (TRPs);

[0055] 3. Road damage compensation.

[0056] Based on the uplink power control in current LTE systems, two path loss compensation methods are considered: full path loss compensation and partial path loss compensation. In NR systems, it can be considered that the terminal uses a specific type of reference signal (RS) to measure the reference signal receiving power (RSRP). The UE then uses RSRP to derive the path loss between the UE and its associated base station (the next generation Node B, gNB).

[0057] By taking into account the estimated path loss, the uplink transmission power from the UE is fully or partially compensated. First, full path loss compensation maximizes fairness for cell-edge UEs; in other words, the power received by the gNB from a cell-edge UE will be comparable to that received from a cell-center UE. On the other hand, if partial path loss compensation is used, the gNB-side received power from a cell-center UE will be significantly higher than that from a cell-edge UE. Compensating for the path loss of cell-edge UEs can be achieved by adjusting other power parameters or offsets so that the received power from cell-edge UEs can be appropriately controlled, while the power received from cell-center UEs may be redundant due to the already sufficient received power.

[0058] In the case of uplink data channel transmission, this redundant power can be used to improve spectral efficiency by applying a higher modulation and coding scheme (MCS) level (e.g., a cell-center UE can use a smaller number of physical resource blocks (PRBs) for the same transport block (TB) size). On the other hand, in the case of uplink control channel transmission using a fixed amount of resources, it is unclear how redundant power can be used to improve spectral efficiency, since the uplink control information (UCI) size will not depend on the UE location or channel conditions. Therefore, it is best to consider full compensation of uplink control channel power control.

[0059] In addition, in the case of partial path loss compensation for uplink data channel transmission, the value of the partial path loss compensation factor can be used to adjust the received power difference between the cell center UE and the cell edge UE, and this value can be different according to the cell radius and target performance.

[0060] 4. Transmit Power Control (TPC) command

[0061] TPC commands can be used to compensate for channel variations caused by fast fading. With respect to current LTE, the Physical Uplink Control Channel (PUCCH) power can be adjusted by TPC commands signaled in the downlink allocation Downlink Control Information (DCI), while the Physical Uplink Shared Channel (PUSCH) (or Sounding Reference Signal (SRS)) power can be adjusted by TPC commands signaled in the uplink grant DCI. In addition, for uplink transmissions without associated DCI, such as semi-persistent scheduling (SPS), periodic Channel State Information (CSI), or SRS, TPC commands can be signaled to a specific terminal group (UE group) by using DCI format 3 / 3A. There are two types of TPC procedures for updating the uplink transmit power; one is cumulative TPC and the other is absolute TPC. Cumulative TPC is well suited for fine-tuning UE transmit power by using relatively small step sizes of TPC values. On the other hand, absolute TPC can be used to immediately increase UE transmit power by using a relatively large step size of the TPC value.

[0062] 5. Additional functions of power control in NR.

[0063] In NR design, it is necessary to consider deployments based on analog (or hybrid) beamforming, especially for high-frequency bands (e.g., above 6 GHz). With such analog beamforming, gNB transmit (TX) / receive (RX) beam scanning (e.g., time division multiplexing (TDM) between different gNB TX / RX beams) may be required not only to transmit downlink common signals and information, such as synchronization signals (e.g., Primary Synchronization Signal (PSS) / Secondary Synchronization Signal (SSS) in LTE) or broadcast system information (e.g., Physical Broadcast Channel (PBCH) in LTE), but also for uplink and downlink control and data channels to serve UEs located in different areas (or beam directions). In this case, it may be necessary to consider differentiating power control parameters between different beams for a UE, as the power required for UE performance will be different for each beam of the UE.

[0064] Typically, the amount of information transmitted through the uplink data channel will be much larger than that of the uplink control channel. Therefore, the power required for transmission of the uplink data channel will also be greater than that of the uplink control channel. For NR design, TDM is considered for the multiplexing structure between uplink data and control channels to reduce latency, flexible uplink and downlink configurations, and analog beamforming. In the case where uplink data and control channels are multiplexed via TDM, it is necessary to deal with the power imbalance between these two different channels, which may be larger than that of current LTE. In addition, considering the various OFDM numerologies used for NR (for example, different subcarrier spacing or symbol duration), it is also necessary to deal with the power transient periods between the uplink data and control channels for certain numerologies (such as large subcarrier spacing).

[0065] 6. Power control per TRP and per layer.

[0066] For high frequency bands in NR, the number of primary rays per TRP or single panel may be limited, and in order to achieve high single-user (SU) multiple-input multiple-output (MIMO) spectrum efficiency, coordinated transmission schemes across multiple TRPs need to be thoroughly studied in NR, including coordinated multiple points (CoMP) dynamic point selection (DPS) and independent layer joint transmission (JT). When the downlink-related DCI indicates the transmission rank and the coordination scheme applied, the DCI decoding latency on the UE side may be a major issue whenever simulated beamforming is applied in a given time instance. This is because the DCI transmission can be performed by the serving TRP, but as an example, the actual data transmission can be performed by another TRP.

[0067] In the case of independent layer JT, where specific layers can be transmitted from different TRPs, the uplink transmit power corresponding to each layer group may need to be configured and controlled by the gNB, as at least the path loss from different TRPs may be different. In addition, separate uplink power control procedures for different TRPs require further study in the context of uplink CoMP.

[0068] 7. Random access process

[0069] In the prior art, a random access procedure may be a contention-based random access procedure or a non-contention-based random access procedure. The random access procedure may be a four-step random access procedure (also called a first type (Type-1) random access procedure) or a two-step random access procedure (also called a second type (Type-2) random access procedure).

[0070] In the contention-based 4-step Random Access Channel (RACH), the UE first sends Message 1 (Msg1) to the network, which contains a preamble. After the network detects the preamble, it sends Message 2 (Msg2) or / and a Random Access Response (RAR) message, which contains the preamble number detected by the network and the uplink radio resources allocated to the UE for sending Message 3 (Msg3). After receiving Msg2, the UE confirms that at least one of the preamble numbers carried in Msg2 matches the number of the preamble it sent. Then, based on the resources indicated by the RAR, it sends Msg3 containing contention resolution information. After receiving Msg3, the network sends Message 4 (Msg4) containing contention resolution information. Upon receiving Msg4, the UE confirms that the resolution information is consistent with the one it sent in Msg3, thus completing the 4-step random access.

[0071] The network includes UL grant information in the RAR to indicate the scheduling information of the Msg3 Physical Uplink Shared Channel (PUSCH), and includes information such as the random access preamble identifier (RACH preamble ID, RAPID), temporary cell radio network temporary identifier (Temporary Cell RNTI C-RNTI, TC-RNTI), timing advance (TA), etc. If the network does not receive the Msg3 PUSCH, it can schedule the retransmission of the Msg3 PUSCH in the Physical Downlink Control Channel (PDCCH) scrambled by the TC-RNTI.

[0072] In the contention-based random access process, different UEs randomly select preambles for transmission. This means that different UEs may select the same preamble for transmission on the same time-frequency radio resource (random access opportunity (RACH Occasion, RO resource). This situation can be understood as a UE preamble conflict. In this case, different UEs will receive the same RAR. At this time, different UEs will transmit Msg3 PUSCH based on the scheduling information in the RAR UL grant. Because the existing technology does not support repeated transmission of Msg3 PUSCH, the network can only decode the PUSCH (including contention resolution information) sent by one UE on a Msg3 PUSCH scheduling resource. Therefore, the network will include the contention resolution information received in Msg3 in Msg4. If the contention resolution information in Msg4 received by the UE matches the contention resolution information sent by the UE in Msg3 PUSCH, the UE considers contention resolution successful. If they do not match, contention resolution is considered unsuccessful.

[0073] If the contention resolution is unsuccessful, the UE reselects RACH transmission resources, performs PRACH transmission, and makes the next random access attempt.

[0074] In NR Release 16 (Rel-16), the two-step random access procedure (2-step RACH) was introduced. The first step is for the UE to send Message A (MsgA) to the network. After receiving MsgA, the network sends Message B (MsgB) to the UE. If the UE does not receive MsgB within a certain period of time, the UE increments the counter that counts the number of times MsgA has been sent and resends MsgA. If the counter counts the number of times MsgA has been sent, the UE switches from the 2-step random access procedure to the 4-step random access procedure.

[0075] MsgA consists of the MsgA preamble and MsgA PUSCH components. The preamble is sent on the Ro used for 2-step RACH, and the PUSCH is sent on the MsgA PUSCH resources associated with the MsgA preamble and Ro. MsgA PUSCH resources are a set of PUSCH resources configured for each PRACH slot, including time-frequency resources and demodulation reference signal (DMRS) resources. They are associated with the PRACH resources within the Physical Random Access Channel (PRACH) slot.

[0080] The communication processing method, apparatus, communication device, and readable storage medium provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0081] 4 , an embodiment of the present application provides a communication processing method, which is executed by a terminal and includes the following specific steps:

[0082] Step 401: When the terminal operates in full-duplex transmission mode, the terminal selects an uplink transmission resource or determines an uplink transmission behavior according to a resource type or reference signal group corresponding to a first reference signal.

[0083] In this embodiment, full-duplex may be enhanced duplex, enhanced duplex mode, Cross Division Duplex (XDD), enhanced full-duplex, enhanced full-duplex mode, sub-band full-duplex, etc.

[0084] In this embodiment, the first reference signal is one or more reference signals corresponding to (or associated with) uplink transmission, and the one or more reference signals have corresponding reference signal resources or reference signal resource sets. The reference signal resource set includes multiple reference signal resources, and the resource types of the multiple reference signal resources can be the same or different.

[0085] Optionally, the reference signal resources may include time-frequency resources of the reference signal, etc.

[0086] Optionally, the reference signal may include one of the following: synchronization signal block (Synchronization Signal and PBCH block, SSB), channel state information reference signal (CSI-RS), tracking reference signal (TRS), phase tracking reference signal (PTRS), etc.

[0087] Optionally, the resource type corresponding to the first reference signal is a time domain format of a reference signal resource corresponding to the first reference signal or a time domain resource corresponding to a reference signal resource set.

[0088] Optionally, the reference signal group corresponding to the first reference signal is used to represent the grouping of the time domain resources where the first reference signal is located. Optionally, the reference signal group corresponding to the first reference signal can be determined according to the reference signal resource or reference signal resource set corresponding to the first reference signal.

[0089] In one implementation manner of the present application, the resource type is a reference signal resource or a time domain resource format corresponding to a reference signal resource set.

[0090] In this embodiment, the first reference signal may be associated with the uplink transmission resource in the following manner:

[0091] Mode 1: Reference signals or reference signal sets corresponding to different resource types are associated with uplink transmission resources corresponding to the same uplink transmission configuration.

[0092] For example, the reference signal in the DL slot corresponds to resource type A, while the reference signal in the DL subband of the X slot corresponds to resource type B. Resource type A and resource type B correspond to the same uplink transmission resource. This allows for selecting the appropriate reference signal based on the different resource types associated with the uplink transmission resource, facilitating differentiation between terminals operating in different duplex transmission modes.

[0093] Alternatively, in mode 2, reference signals or reference signal sets corresponding to different resource types are associated with uplink transmission resources corresponding to different uplink transmission configurations.

[0094] In this case, the complexity of associating the reference signal with the uplink transmission resource can be reduced, and there is no need to distinguish between different types of reference signals.

[0095] Alternatively, mode 3: the reference signals or reference signal sets corresponding to different reference signal groups are associated with uplink transmission resources corresponding to the same uplink transmission configuration;

[0096] Alternatively, in mode 4, reference signals or reference signal sets corresponding to different reference signal groups are associated with uplink transmission resources corresponding to different uplink transmission configurations.

[0097] In one embodiment of the present application, the resource type of the reference signal resource or the reference signal resource set includes at least one of the following:

[0098] (1) Type 1, which is used to indicate a time domain resource whose time domain format is downlink, that is, all frequency domain resources on this time domain resource unit are used for downlink (DL) transmission;

[0099] (2) The second type, which is used to represent time domain resources whose time domain format is a first format, where the first format is a time domain format for full-duplex transmission, and the frequency domain resources corresponding to the time domain resources of the first format include a downlink subband (DL subband) and an uplink subband (UL subband), that is, the entire bandwidth on the second type of time domain resources includes a downlink subband and an uplink subband.

[0100] In one embodiment of the present application, the second type includes at least one of the following:

[0101] (1) A third type, where the third type is used to indicate that the time domain format is a time domain resource of the first format, and the interval between the downlink subband and the uplink subband is greater than or equal to a first preset value;

[0102] (2) A fourth type, which is used to indicate that the time domain format is a time domain resource of the first format, and the interval between the downlink subband and the uplink subband is less than or equal to a second preset value.

[0103] It should be noted that the first preset value and the second preset value may be the same or different, and in this embodiment, there is no specific limitation on the first preset value and the second preset value.

[0104] In one embodiment of the present application, the reference signal group includes at least one of the following:

[0105] (1) a first reference signal group, the first reference signal group including reference signals located in time domain resources whose time domain format is downlink;

[0106] For example, the first reference signal set includes reference signals located on a first type of time domain resources.

[0107] Optionally, the reference signal may include one of the following: SSB, CSI-RS, TRS, PTRS, etc.

[0108] (2) a second reference signal group, the second reference signal group including reference signals located in time domain resources having a second time domain format;

[0109] The concept of the second format is specific to the "time domain." The second format can be expressed as full-duplex, sub-band full-duplex, flexible full-duplex, or enhanced duplex. Furthermore, the second format is a time-domain format for full-duplex transmission. The frequency-domain resources corresponding to the time-domain resources of the second format include uplink subbands and downlink subbands.

[0110] For example, the second reference signal set includes reference signals located on the second type of time domain resources.

[0111] (3) a third reference signal group, the third reference signal group including reference signals located in time domain resources having a time domain format of the second format, and an interval between a downlink subband and an uplink subband being greater than or equal to a third preset value;

[0112] For example, the third reference signal set includes reference signals located on a third type of time domain resources.

[0113] (4) a fourth reference signal group, the fourth reference signal group including reference signals located in time domain resources having a time domain format of the second format, and an interval between a downlink subband and an uplink subband being less than or equal to a fourth preset value;

[0114] For example, the fourth reference signal set includes reference signals located on a fourth type of time domain resources.

[0115] It should be noted that the third preset value and the fourth preset value may be the same as or different from each other, and in this embodiment, no specific limitation is imposed on the third preset value and the fourth preset value.

[0116] In one embodiment of the present application, the reference signals in different reference signal groups among the first reference signal group, the second reference signal group, the third reference signal group, and the fourth reference signal group are the same or different. For example, different reference signal groups among the first reference signal group, the second reference signal group, the third reference signal group, and the fourth reference signal group may contain the same reference signal index.

[0117] Optionally, the reference signals in the first reference signal group, the second reference signal group, the third reference signal group, or the fourth reference signal group may be configured in the following manner:

[0118] (1) Independent reference signal configuration;

[0119] That is, different reference signal groups have different reference signal configurations. For example, a reference signal on a DL subband is configured with a certain reference signal configuration, while a reference signal on a Full DL is configured with another reference signal configuration.

[0120] (2) The common reference signal configuration is configured.

[0121] That is, the same reference signal configuration is used to configure two possible types of reference signals. For example, the same reference signal configuration is used for the first reference signal group and the second reference signal group.

[0122] In one embodiment of the present application, the reference signal group satisfies one or more of the following conditions:

[0169] The following describes the implementation of the present application in conjunction with Example 1, Example 2 and Example 3.

[0170] Example 1:

[0171] The first reference signal may include a first reference signal group and a second reference signal group. The first reference signal group corresponds to a time domain resource of the first type whose time domain format is DL; the second reference signal group corresponds to a time domain resource of the second type whose time domain format is the first format, where the first format is a time domain format for full-duplex transmission, and the frequency domain resources corresponding to the time domain resource of the first format include an uplink subband and a downlink subband.

[0172] The first reference signal group may be used for a UE in a non-full-duplex mode, that is, a UE in a half-duplex mode.

[0173] The second reference signal group may be used for UEs in full-duplex mode.

[0174] In one embodiment, the UE is a half-duplex mode UE. Based on a first reference signal group, the UE selects an uplink transmission resource corresponding to the first reference signal group, such as a random access resource, and sends an uplink transmission in the corresponding time-frequency domain resource. Furthermore, based on the spatial characteristics corresponding to the first reference signal group, the corresponding uplink transmission is sent. Specifically, based on the random access resource associated with the first reference signal group, such as an RO or a preamble, Msg1 or MsgA is sent. Furthermore, based on the first reference signal group associated with the sent Msg1 or MsgA, Msg3, common PUCCH, or Msg5 is sent subsequently in the random access process.

[0175] In another implementation manner, the UE is a full-duplex mode UE, and based on the second reference signal group, the UE selects the uplink transmission resources corresponding to the second reference signal group, and sends uplink transmission in the corresponding time-frequency domain resources. Further, based on the spatial characteristics corresponding to the second reference signal group, the corresponding uplink transmission is sent. Further, based on the spatial characteristics corresponding to the second reference signal group, the corresponding uplink transmission is sent. Specifically, based on the random access resources associated with the second reference signal group, such as RO or preamble, Msg1 or MsgA is sent. Further, based on the second reference signal group associated with the sent Msg1 or MsgA, Msg3, common PUCCH or Msg5 is sent subsequently in the random access process.

[0176] Example 2:

[0177] The first reference signal may include a first reference signal group and a second reference signal group. The first reference signal group corresponds to a time domain resource of the first type whose time domain format is DL; the second reference signal group corresponds to a time domain resource of the second type whose time domain format is the first format, where the first format is a time domain format for full-duplex transmission, and the frequency domain resources corresponding to the time domain resource of the first format include an uplink subband and a downlink subband.

[0180] In one embodiment, corresponding uplink transmission resources are configured based on different reference signal groups. Specifically, uplink transmission resource 1 is configured based on the first reference signal group and is associated with the first reference signal group; and uplink transmission resource 2 is configured based on the second reference signal group and is associated with the second reference signal group.

[0181] Example 3:

[0182] The first reference signal may include a first reference signal group and a second reference signal group. The first reference signal group corresponds to a time domain resource of the first type whose time domain format is DL; the second reference signal group corresponds to a time domain resource of the second type whose time domain format is the first format, where the first format is a time domain format for full-duplex transmission, and the frequency domain resources corresponding to the time domain resource of the first format include an uplink subband and a downlink subband.

[0183] The first reference signal group may be used for a UE in a non-full-duplex mode, that is, a UE in a half-duplex mode.

[0184] The second reference signal group may be used for UEs in full-duplex mode.

[0185] In one embodiment, when a UE initiates CG-SDT or SRS transmission in a non-connected state, based on the reference signal associated with the CG-SDT or SRS, such as the first reference signal group, and at the same time, based on the RSRP threshold corresponding to the first reference signal group, if the RSRP threshold is met, the UE initiates CG-SDT or SRS transmission based on the first reference signal group.

[0186] Another implementation method includes: the UE is based on a certain reference signal group, such as the second reference signal group, and the corresponding RSRP threshold. If the RSRP threshold is met, the UE selects the CG-SDT or SRS resources associated with the second reference signal group for transmission.

[0187] In one embodiment, when a UE initiates CG-SDT or SRS transmission in a non-connected state, based on a reference signal associated with the CG-SDT or SRS, such as a first reference signal group, and based on a TA validation threshold corresponding to the first reference signal group, if the TA validation threshold is met, the UE initiates CG-SDT or SRS transmission based on the first reference signal group.

[0188] Another implementation includes: the UE is based on a reference signal group, such as the second reference signal group, and a corresponding TA validation threshold. If the TA validation threshold is met, the UE selects the CG-SDT or SRS resources associated with the second reference signal group for transmission.
