[0021] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

The character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0023] 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 described technology 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 descriptions, but these technologies can also be applied to systems other than NR system applications, such as the 6th generation (6 th Generation, 6G) communication system.

[0024] In order to facilitate understanding of the embodiments of the present application, the following technical points are first introduced:

[0025] 1. Full Duplex (FD) mode.

[0026] In the fifth generation mobile communication technology (5G) mobile communication system, full duplex enhancement technology is used to adapt to diverse scenarios and business requirements. The main scenarios of 5G include enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine type communications (mMTC). These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage.

[0027] In the New Radio (NR), configuring full-duplex operation can significantly improve the latency and coverage performance of the Time Division Duplexing (TDD) system.

[0028] 1.1. Subbands non-overlapping Full duplex.

[0029] Sub-band non-overlapping full-duplex can improve transmission delay and enhance coverage.

[0030] For a downlink (DL) slot (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), the network configures the DL bandwidth part (Bandwidth Part, BWP) for (e.g., User Equipment (UE)), and for an uplink (UL) slot, the network configures the ULBWP for the UE. For example, slot 1 and slot 4.

[0031] For full duplex scenarios, there are the following examples: Figure 1 and Figure 2 shown.

[0032] Example 1: Configure DL BWP, that is, slot 1.

[0033] Example 2: Configure DL BWP and UL sub-band, namely slot 2.

[0034] A UL slot is configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated.

[0035] Example 3: Configure UL BWP, that is, slot 4.

[0036] Example 4: Configure UL BWP and DL sub band, that is, slot5.

[0037] For SubBand Full Duplex (SBFD) operation, one SBFD subband is composed of one resource block (RB) or a set of consecutive RBs with the same transmission direction.

[0038] A time unit (eg, slot or symbol) in which the base station uses SBFD operation may be referred to as a SBFD time unit (eg, slot or symbol).

[0039] For Release 15 (Rel-15), the base station and the UE can only send or receive at one time.

[0040] For Release 18 (Rel-18) base station side full-duplex, the base station can send and receive at the same time, and the UE side can only use half-duplex mode, that is, it can only send or receive at a time.

[0041] For full-duplex on the UE side, the gNB and UE can transmit and receive simultaneously.

[0042] 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.

[0043] For a communication device, simultaneous UL reception and DL transmission will cause self-interference. In order to ensure transmission in the interfered direction, the communication device needs to have the ability to eliminate self-interference, such as reserving a guard band between the receiving band and the transmitting band, but this will reduce the UE throughput.

[0044] In 5G and future 6G systems, both base stations and terminals may adopt full-duplex mode.

[0045] 2. Uplink power control:

[0046] In the design of the new air interface system, new features are considered in the uplink, such as uplink transmission based on orthogonal frequency division multiplexing (OFDM) and single-symbol uplink control channel. Uplink power control is also an important content, including the following knowledge points:

[0047] i. There is no cell-specific reference signal similar to Long Term Evolution (LTE) for path loss estimation;

[0048] ii. Beam-based transmission / reception;

[0049] iii. Analog beamforming at the base station or terminal;

[0050] iv. Multi-beam or multi-stream transmission;

[0051] v. Multiple parameter sets (numerology);

[0052] vi. Information exchange between Transmission and Receiving Point (TRP);

[0053] 3. Road damage compensation.

[0054] According to the uplink power control in the current LTE system, two path loss compensation methods are considered; one is full path loss compensation and the other is partial path loss compensation. In the NR system, it can be considered that the terminal measures the reference signal receiving power (RSRP) by using a specific type of reference signal (RS), and then the UE uses RSRP to derive the path loss between the UE and its associated base station (the next Generation Node B, gNB).

[0055] By taking into account the estimated path loss, the uplink transmission power from the UE will be fully or partially compensated. First, full path loss compensation can maximize fairness to cell-edge UEs, in other words, the power received on the gNB side from cell-edge UEs will be comparable to the power received from cell-center UEs. On the other hand, if partial path loss compensation is used, the gNB-side received power from cell-center UEs will be much higher than that from cell-edge UEs. The path loss of cell-edge UEs can be compensated by adjusting other power parameters or offsets so that the power received 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.

[0056] In case of uplink data channel transmission, this redundant power can be used to improve spectrum efficiency by applying higher modulation and coding scheme (MCS) level (e.g. cell center UE can use fewer number of physical resource blocks (PRB) for the same transport block (TB) size). On the other hand, in case of uplink control channel transmission using fixed amount of resources, it is not clear how to use redundant power to improve spectrum efficiency, because uplink control information (UCI) size will not depend on UE location or channel conditions. Therefore, it is better to consider full compensation of uplink control channel power control.

[0057] 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 vary according to the cell radius and target performance.

[0058] 4. Transmit Power Control (TPC) command

[0059] 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 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 steps 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.

[0060] 5. Additional functions of power control in NR.

[0061] In NR design, it is necessary to consider deployment 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 for the transmission of 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 the transmission of 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 the differentiation of power control parameters between different beams for UEs, because the power required for UE performance will be different for each beam of the UE.

[0062] Typically, the amount of information transmitted through the uplink data channel will be much larger than the uplink control channel. Therefore, the power required for uplink data channel transmission will also be greater than the power 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 the 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 the current LTE. In addition, considering the various OFDM numerologies used for NR (e.g., different subcarrier spacing or symbol duration), it is also necessary to handle the power transient periods between the uplink data and control channels for certain numerologies (e.g., large subcarrier spacing).

[0063] 6. Power control per TRP and per layer.

[0064] 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 applied coordination scheme, the DCI decoding delay on the UE side may be a major problem 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.

[0065] In the case of independent layer JT, where specific layers may be transmitted from different TRPs, the uplink transmit power corresponding to each layer group may need to be configured and controlled by the gNB, since at least the path loss from different TRPs may be different. In addition, separate uplink power control procedures for different TRPs need to be further studied in the context of uplink CoMP.

[0066] 7. Random access process

[0067] In the prior art, the random access process may be a contention-based random access process or a non-contention-based random access process. The random access process may be a four-step random access process (also called a first type (Type-1) random access process) or a two-step random access process (also called a second type (Type-2) random access process).

[0068] In the contention-based 4-step Random Access Channel (RACH), the UE first sends message 1 (Msg1) to the network, including a preamble; after the network detects the preamble, it sends message 2 (Msg2) or / Random Access Response (RAR) message, including the number of the preamble detected by the network and the uplink radio resources allocated to the UE to send message 3 (Msg3); after receiving msg2, the UE confirms that at least one of the numbers of the preamble carried in msg2 is consistent with the number of the preamble sent by itself, and then sends Msg3 containing contention resolution information according to the resources indicated by RAR; after receiving Msg3, the network sends message 4 (Msg4) containing contention resolution information; after receiving Msg4, the UE confirms that the resolution information is consistent with that sent by itself in Msg3, thus completing the 4-step random access.

[0069] The network includes UL grant information in the RAR to indicate the scheduling information of the Msg3 physical uplink shared channel (PUSCH), and includes the random access preamble identifier (RACHpreamble 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 TC-RNTI scrambled physical downlink control channel (PDCCH).

[0070] For the contention random access process, different UEs randomly select preambles for transmission, so different UEs may select the same preamble to send on the same time-frequency radio resource (random access opportunity (RACH Occasion, RO resource), which can be understood as a preamble conflict of the UE. In this case, different UEs will receive the same RAR, and at this time, different UEs will transmit Msg3 PUSCH according to the scheduling information in the RAR UL grant. Since the prior art does not support repeated transmission of Msg3 PUSCH, the network can only decode a PUSCH (including contention resolution information) sent by one UE on one Msg3 PUSCH scheduling resource, so 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 that the contention resolution is successful. If they do not match, the contention resolution is considered unsuccessful.

[0071] If the contention resolution is unsuccessful, the UE reselects RACH transmission resources, performs PRACH transmission, and makes the next random access attempt.

[0072] In NR version 16 (Release 16, Rel-16), the two-step random access process (2-step RACH) was introduced. The first step is that the UE sends message A (MsgA) to the network side. After receiving MsgA, the network side sends message B (MsgB) to the UE. If the UE does not receive MsgB within a certain period of time, the UE will add a counter that counts the number of times MsgA is sent and resend MsgA. If the counter that counts the number of times MsgA is sent reaches a certain threshold, the UE will switch from the 2-step random access process to the four-step (4-step) random access process.

[0073] MsgA includes MsgApreamble and MsgAPUSCH. The preamble is sent on the RO 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, and are associated with the PRACH resources in the Physical Random Access Channel (PRACH) slot.

[0078] 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 the accompanying drawings through some embodiments and their application scenarios.

[0079] See also Figure 4 , the embodiment of the present application provides a communication processing method, which is executed by a terminal, and the specific steps include:

[0080] 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 a reference signal group corresponding to a first reference signal.

[0081] 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.

[0082] 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.

[0083] Optionally, the reference signal resources may include time-frequency resources of the reference signal, etc.

[0084] Optionally, the reference signal may include one of the following: synchronization signal block (Synchronization Signal and PBCH block, SSB), channel state information reference signal (Channel State Information Reference Signal, CSI-RS), tracking reference signal (Tracking Reference Signal, TRS), phase tracking reference signal (Phase-Tracking Reference Signals, PTRS), etc.

[0085] 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.

[0086] Optionally, the reference signal group corresponding to the first reference signal is used to represent the grouping of 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.

[0087] In an 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.

[0088] In this embodiment, the first reference signal may be associated with the uplink transmission resource in the following manner:

[0089] 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.

[0090] For example, the resource type corresponding to the reference signal in the DL slot is resource type A, and the resource type corresponding to the reference signal in the DL subband of the X slot is resource type B. Resource type A and resource type B correspond to the same uplink transmission resource. In this way, a suitable reference signal can be selected according to different resource types associated with the uplink transmission resource, which is conducive to distinguishing terminals in different duplex transmission modes.

[0091] 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.

[0092] 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.

[0093] 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;

[0094] 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.

[0095] In one implementation 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:

[0096] (1) Type 1, which is used to indicate that the time domain format is a downlink time domain resource, that is, all frequency domain resources on this time domain resource unit are used for downlink (DL) transmission;

[0097] (2) The second type, the second type is used to represent time domain resources whose time domain format is a first format, 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.

[0098] In one embodiment of the present application, the second type includes at least one of the following:

[0099] (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;

[0100] (2) A fourth type, where the fourth type is used to indicate that the time domain format of the time domain resource is the first format, and the interval between the downlink subband and the uplink subband is less than or equal to a second preset value.

[0101] It should be noted that the first preset value and the second preset value may be the same or different, and in this embodiment, no specific limitation is made to the first preset value and the second preset value.

[0102] In one implementation of the present application, the reference signal group includes at least one of the following:

[0103] (1) a first reference signal group, the first reference signal group including reference signals located in a time domain resource whose time domain format is downlink;

[0104] For example, the first reference signal set includes reference signals located on time domain resources of a first type.

[0105] Optionally, the reference signal may include one of the following: SSB, CSI-RS, TRS, PTRS, etc.

[0106] (2) a second reference signal group, wherein the second reference signal includes reference signals located in time domain resources whose time domain format is a second format;

[0107] The concept of the second format is for the "time domain". The second format can be expressed as full duplex, or sub-band full duplex, or flexible full duplex, or enhanced duplex, etc. Further, the second format is a time domain format for full duplex transmission, and the frequency domain resources corresponding to the time domain resources of the second format include uplink subbands and downlink subbands.

[0108] For example, the second reference signal set includes reference signals located on the second type of time domain resources.

[0109] (3) a third reference signal group, the third reference signal group including reference signals located in time domain resources whose time domain format is the second format, and an interval between a downlink subband and an uplink subband is greater than or equal to a third preset value;

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

[0111] (4) a fourth reference signal group, the fourth reference signal group including reference signals located in time domain resources whose time domain format is the second format, and an interval between a downlink subband and an uplink subband is less than or equal to a fourth preset value;

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

[0113] It should be noted that the third preset value and the fourth preset value may be the same or different, and in this embodiment, the third preset value and the fourth preset value are not specifically limited.

[0114] 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 may be 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 include the same reference signal index.

[0115] 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:

[0116] (1) Configured by independent reference signal configurations;

[0117] That is, for different reference signal groups, there are different reference signal configurations. For example, the reference signals on the DL subband are configured with a certain reference signal configuration; the reference signals on the Full DL are configured with another reference signal configuration.

[0118] (2) Configured by common reference signal configurations.

[0183] Another implementation method includes: the UE is based on a reference signal group, such as the second reference signal group, and a 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.
