Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to an information processing method and apparatus, communication equipment and storage medium. Background Technology

[0002] Non-Terrestrial Networks (NTNs) differ from Terrestrial Networks (TNs). Because NTNs utilize satellite-based access or relay equipment, the distance between them and ground-based UEs is greater, resulting in higher path loss and limited coverage of some channels, such as the Physical Uplink Shared Channel (PUSCH). Simulation results in NTNs show that PUSCH coverage can be improved by bundling demodulation reference signals (DMRS), and uplink coverage requirements can be met when the time domain window (TDW) of the DMRS bundling is sufficiently large. However, when the TDW is not large enough, other methods may be needed. Summary of the Invention

[0009] A fourth aspect of this disclosure provides a computer storage medium storing an executable program; the executable program, when executed by a processor, can implement the technical solution provided in the first aspect above.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure.

[0037] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, words used herein may be interpreted as meaning "when," "when," or "in response to a determination."

[0038] Please refer to Figure 1A This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1A As shown, the wireless communication system is a communication system based on cellular mobile communication technology. This wireless communication system may include: a plurality of UEs 11 and a plurality of access devices 12. In some embodiments, the communication system may further include: one or more core network devices, in... Figure 1A Core network equipment is not shown. This core network equipment includes, but is not limited to, Mobile Management Entity (MME) or Access Management Function (AMF).

[0039] UE 11 can be a device that provides voice and / or data connectivity to a user. UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). UE 11 can be an IoT UE, such as a sensor device, a mobile phone (or cellular phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE 11 can also be a device in an unmanned aerial vehicle (UAV). Alternatively, UE 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0040] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as a New Radio, NR, or 5G NR system). Alternatively, it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0041] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0042] Access device 12 and UE 11 can establish a wireless connection via a wireless air interface. In different implementations, this wireless air interface is based on the fourth-generation (4G) mobile communication network technology standard; or, it is based on the fifth-generation (5G) mobile communication network technology standard, such as a new air interface; or, it can be based on a next-generation mobile communication network technology standard based on 5G. Based on DMRS, uplink coverage can be further improved through antenna switching. Different uplink transmissions are associated with different Sounding Reference Signal resource sets (SRSresource sets) or SRS resources. Thus, an antenna switch can be considered to occur between two PUSCHs associated with different SRS resource sets or SRS resources. An SRS resource set includes one or more SRS resources. For example,

[0043] Different Sounding Reference Signal resource sets (SRS resource sets) can be associated with two consecutive PUSCH transmissions. The repetition type of this PUSCH transmission can be repetition type A and repetition type B. Therefore, if the Sounding Reference Signal resource sets (SRS resource sets) or SRS resources associated with the PUSCH transmissions are different, it indicates that antenna switching was performed during the repeated transmission of the PUSCH transmission. Antenna switching can be a switching of physical antennas or antenna ports, such as in repeated uplink channel transmissions. In repeated uplink transmissions, the configured SRS resource set can be switched according to a pre-agreed switching pattern indicated in the DCI, rather than according to the antenna switching interval.

[0044] The protection interval for antenna switching can be specified as follows, as detailed in Table 1:

[0045] μ <![CDATA[Δf=2 u *15[kHz]]]> y [the number of symbols] 0 15 1 1 30 1 2 60 1 3 120 2

[0046] Table 1

[0047] It can be seen that when the UE performs uplink transmission, the antenna switching interval (corresponding to y) is also different when the subcarrier space (SCS) used is different.

[0048] It is worth noting that any row in Table 1 can be used alone, or multiple rows can be used in combination.

[0049] Repeated uplink transmissions can include repeat type A and repeat type B.

[0050] refer to Figure 1B As shown, repetition type A involves transmitting the same TB across multiple time slots that are consecutively distributed in the time domain, and the symbol positions occupied in the multiple time slots are exactly the same. For example, typically, one time slot can correspond to one transmission in multiple repetitive transmissions.

[0051] refer to Figure 1C As shown, repetition type B breaks the time slot boundary, allowing multiple repeated transmissions within a single time slot. A transmission can also span two time slots. Figure 1C A single nominal transmission occupies four consecutively distributed symbols. Figure 1C The first, second, and third rows can be considered as schematic diagrams of two nominal repetition transmissions when repetition type B begins transmission on time slot #1 with different start symbols. For example, Figure 1CThe starting symbol for the third repetition of type B in the third row is symbol 8 of time slot #1 (the symbol count or number within a time slot starts from 0). The second actual repetition of this uplink transmission occupies the last two symbols of time slot #1 and the first two symbols of time slot #2, and the third actual repetition starts from symbol 2 of time slot #2.

[0052] exist Figure 1C In this code, U represents uplink transmission, which can be understood as an abbreviation for Uplink. Rep represents a single, repeated transmission. For example, in... Figure 1C Rep#1 represents the first repeated transmission. Figure 1C Rep#2 in the middle represents the second repeated transmission and in Figure 1C Rep#3 represents the third retransmission.

[0053] If a UE participates in both DMRS bonding and antenna switching during multiple uplink transmissions, antenna switching may violate the power consistency and / or phase continuity requirements of DMRS bonding. Therefore, antenna switching will affect the time domain position of the predetermined TDW. Here, UE participation in DMRS bonding means that, with a nominal TDW length configured and DMRS bonding enabled, the UE maintains power consistency and phase continuity within the actual TDW length to ensure that the base station performs joint DMRS demodulation after receiving the uplink channel.

[0054] In view of this, such as Figure 2A As shown, this disclosure provides an information processing method, which can be executed by a UE or an access device, including:

[0055] S1110: Determine the time domain location of the predetermined TDW based on the antenna switching interval and antenna switching time.

[0056] The UE can be of various types. It may include, but is not limited to: notebooks, tablets, wearable devices, smart home devices, smart office devices, in-vehicle devices, and / or flight devices. In short, the UE can interact with… Figure 1A The access device shown connects to the mobile communication network.

[0057] The access equipment includes, but is not limited to, NTN access equipment. The NTN access equipment may include, but is not limited to, NTN eNBs and / or NTN gNBs. The NTN access equipment may be located on airborne equipment such as satellites, or it may be located on the ground, but the communication signal needs to be relayed or transparently transmitted through other airborne equipment such as satellites.

[0058] The scheduled TDW here can be the actual TDW. The nominal TDW is related to the actual TDW.

[0059] The nominal TDW is a time length configured by network devices such as access devices or predefined rules. This time length is the expected time length when performing DMRS binding or joint channel estimation. Ideally, the UE needs to maintain phase continuity and / or power consistency within the time length corresponding to the nominal TDW if DMRS binding or joint channel estimation is required. Within the time range corresponding to the nominal TDW, if the behavior of the network device and / or the UE causes an event that disrupts the phase continuity and / or power consistency of the UE, then the time range corresponding to the nominal TDW is divided into at least two time periods by the aforementioned event. Any time period during which the UE maintains continuity and / or power consistency can be called the predetermined TDW. Therefore, the duration (also called length) of the predetermined TDW is usually less than or equal to the length of the nominal TDW. This length of the nominal TDW can be the number of time units, for example, the number of time slots and / or symbols.

[0060] One or more uplink transmissions are configured within the nominal TDW. The uplink transmissions here include, but are not limited to, at least one of the following: PUSCH transmission; Physical Uplink Control Channel (PUCCH) transmission.

[0061] For example, assuming the nominal TDW is X time slots, the uplink transmission repeats Y times, and one transmission corresponds to one time slot, then ideally, the number of nominal TDWs is...

[0062] For example, the access device configures nominal TDW and / or antenna handover related information to the UE through messages such as RRC configuration messages, MAC layer signaling, or Downlink Control Information (DCI). This information can be collectively referred to as configuration information. In some embodiments, nominal TDW and / or antenna handover related information can also be configured through predefined rules. These predefined rules include, but are not limited to, protocol conventions.

[0063] The UE may include one or more antenna ports, or in other words, the UE may include one or more antenna panels. When the UE switches antenna panels or antenna ports for uplink transmission, it disrupts phase continuity or power consistency, resulting in a difference between the predetermined TDW and the nominal TDW. Ideally, the predetermined TDW length is equal to the nominal TDW length. However, typically, due to various events that disrupt the UE's uplink power consistency and / or phase continuity, the predetermined TDW length may be less than the nominal TDW length, and / or the time domain position of the predetermined TDW may differ from the time domain position of the nominal TDW.

[0064] This antenna switching of the UE is performed based on relevant information from the configuration information sent by the network device. For example, the access device can configure the UE's antenna switching via RRC messages, MAC layer signaling, or Downlink Control Information (DCI). These configuration RRC messages, MAC layer signaling, or DCI messages may include, but are not limited to, at least one of the following:

[0065] The antenna switching interval can be the time interval between two adjacent antenna switchings; for example, if the antenna switching intervals are equal, the antenna switching interval can be understood as the period of antenna switching.

[0066] The antenna switching period, also known as the guard period or protection interval, is the time domain period during which the UE stops uplink and / or downlink transmissions. In other words, during the antenna switching period, the UE neither transmits nor receives data.

[0067] The antenna switching time is included within the antenna switching interval, is part of the antenna switching interval, or can be the time gap between two adjacent antenna switching intervals.

[0068] For example, corresponding to an antenna switching interval, the UE can perform one or more antenna switching operations, and the duration required for each antenna switching operation can be the aforementioned antenna switching time. In some cases, the antenna switching time is also referred to as the antenna switching duration or the antenna switching guard interval, etc.

[0069] In some embodiments, the information related to antenna switching for the UE can be defined by predefined rules. In this case, the access device can instruct the antenna to switch antennas based on the predefined rules, or simply specify which predefined rule to switch antennas based on.

[0070] In this embodiment of the disclosure, determining the time domain location of the predetermined TDW based on the nominal TDW, antenna switching interval, and / or antenna switching time may include at least one of the following:

[0071] The starting time domain position of the predetermined TDW is determined based on the antenna switching interval and antenna switching time.

[0072] The termination time domain position (or cutoff time domain position) of the predetermined TDW is determined based on the antenna switching interval and antenna switching time.

[0073] The length of the predetermined TDW is determined based on the antenna switching interval and antenna switching time, which is the number of time units contained between the start and end time domain positions. This time unit may include, but is not limited to, time slots and / or symbols.

[0074] In the specific implementation process, when switching the time domain position of the predetermined TDW according to the antenna switching interval and antenna switching time, the time domain position of the predetermined TDW can be further determined by combining the nominal TDW.

[0075] Thus, when both DMRS binding and antenna switching functions of the UE are enabled, the UE and / or access device will determine the time domain position of the predetermined TDW based on the nominal TDW, antenna switching interval and antenna switching time, thereby enabling the access device to perform joint channel estimation based on the predetermined TDW.

[0076] For example, if the execution subject of the time-domain location determination method of the predetermined TDW is a UE, the method may further include:

[0077] Based on the time-domain location of the predetermined TDW, the UE sends time-domain information of the predetermined TDW to the access device, which indicates the time-domain location and / or length of the predetermined TDW. In this way, the UE can assist the access device in determining the predetermined TDW used for joint channel estimation and calculate the predetermined TDW for uplink transmission enhancement based on the joint channel estimation.

[0078] In this embodiment of the disclosure, the UE or access device will determine the time domain position of the predetermined TDW at least based on the antenna switching interval and the antenna switching time, thereby improving the accuracy of the predetermined TDW.

[0079] For example, the time-domain location determination method for a predetermined TDW provided in this disclosure embodiment may include at least one or more of the following:

[0080] When the UE performs antenna switching and no event occurs that disrupts phase continuity and / or power consistency, the time domain location of the predetermined TDW is determined based on the nominal TDW, the antenna switching interval, and the antenna switching time.

[0081] When the UE performs antenna switching and an event that disrupts phase continuity and / or power consistency occurs, the time domain location of the predetermined TDW is determined based on the nominal TDW, antenna switching interval, antenna switching time, and the time domain location where the disruption event occurred.

[0082] If no antenna switching occurs at the UE but an event disrupting phase continuity and / or power consistency occurs, the time domain location of the predetermined TDW is determined based on the nominal TDW and the time domain location where the disruption event occurred.

[0083] The acts of sabotage here may include, but are not limited to, at least one of the following:

[0084] Based on the configuration of the access device, pause uplink transmission and switch to downlink transmission or downlink monitoring;

[0085] Destructive events caused by UE behavior.

[0086] UE behavior may include, but is not limited to, at least one of the following:

[0087] UE timing advance (TA);

[0088] The UE performs frequency pre-compensation.

[0089] The TA adjustment by the UE here may include: the movement of the UE and / or the movement of airborne equipment such as satellites, which causes a change in the relative distance between the UE and the airborne equipment, resulting in an increase or / or a decrease in the TA. For example, a decrease in the relative distance between the UE and the NTN base station causes a decrease in the TA; or a decrease in the relative distance between the UE and the NTN base station causes an increase in the TA.

[0090] Thus, subsequent uplink events of the UE, based on the adjusted TA, will occur earlier in the corresponding time unit, which may disrupt phase continuity.

[0091] The time precompensation here may include time precompensation based on TA, and / or precompensation based on other time quantities besides other TAs.

[0092] Therefore, considering the impact of antenna switching on the predetermined TDW, determining the predetermined TDW based on the antenna switching interval and antenna switching time can improve the accuracy of determining the time domain location of the predetermined TDW.

[0093] like Figure 2B As shown, this disclosure provides a method for determining the time-domain location of a predetermined TDW, which can be executed by a UE or an access device, and includes:

[0094] S1210: Determine the time domain position of the predetermined TDW based on the uplink transmission time domain position, antenna switching interval, and antenna switching time.

[0095] For example, the length of the antenna switching interval can be understood as the number of time units occupied by the antenna switching interval, such as the number of time slots and / or symbols occupied by the antenna switching interval.

[0096] The uplink transmissions mentioned here include, but are not limited to, PUSCH-based transmissions and PUCCH-based transmissions. These PUSCH and / or PUCCH transmissions can be dynamically, semi-statically, or statically configured by the access device. Therefore, the time-domain location of each uplink transmission in a repeated transmission is known in advance by both the UE and the access device. In this way, a time gain in uplink transmission can be achieved through repeated transmissions.

[0097] For example, the access device can configure the time-domain position of uplink transmission via higher-layer signaling. If the uplink transmission is a repeated transmission, the time-domain position of each uplink transmission can be determined according to the higher-layer signaling. For example, the start and end time-domain positions of each uplink transmission can be determined. The start time-domain position can be represented by a symbol at the beginning of the time domain. This starting symbol can be simply referred to as the start symbol. That is, the start time-domain position can be represented by a start symbol. Similarly, the start time-domain position can be represented by a symbol at the end of the time domain. This ending symbol can be simply referred to as the end symbol or cutoff symbol. That is, the end time-domain position can also be represented by a stop symbol.

[0098] The higher-level signaling here may include: MAC layer signaling and / or RRC signaling.

[0099] For example, the antenna switching interval and antenna switching time can be used to determine the time-domain location where the antenna switching occurs. The time-domain location of the predetermined TDW is related to the time-domain location of the uplink transmission. Therefore, in this embodiment of the disclosure, the time-domain location of the predetermined TDW is determined based on the antenna switching interval, antenna switching time, and the time-domain location of the uplink transmission.

[0100] like Figure 2C As shown, this disclosure provides an information processing method, which can be executed by a UE or an access device, including:

[0101] S1310: Determine the preset time domain position for antenna switching based on the antenna switching interval and antenna switching time;

[0102] S1320: Determine the time domain position of the predetermined TDW based on the preset time domain position of antenna switching and the time domain position of uplink transmission.

[0103] In this embodiment of the disclosure, the antenna switching interval and antenna switching time are determined according to configuration information or predefined rules.

[0104] This configuration information can be carried via RRC messages, MAC layer signaling, or DCI. These predefined rules include, but are not limited to, protocol agreements.

[0105] For example, the configuration information or predefined rules may include:

[0106] The first piece of information indicates the duration of the antenna switching interval and / or the start and end positions in the time domain;

[0107] The second piece of information indicates the duration of antenna switching.

[0108] For example, the antenna switching time is included in the antenna switching interval, or it can be the interval between two adjacent antenna switching intervals.

[0109] For example, assuming the antenna switching time is included within the antenna switching interval, if the antenna switching interval is equal to m time slots, then the UE will perform an antenna switch every m time slots. This antenna switching may include switching of the antenna port used for uplink transmission, switching of the antenna panel, and / or switching of the antenna polarization direction, etc. As another example, assuming the antenna switching interval does not include the antenna switching time, then the UE will perform a switch of the antenna port, antenna panel, or antenna polarization direction for uplink transmission every antenna switching time and the duration of the antenna switching interval. Therefore, based on the antenna switching interval and the antenna switching time, the time-domain location where the UE's antenna switching occurs can be determined. This time-domain location where the antenna switching occurs (i.e., the aforementioned preset time-domain location of the antenna switching) may include: the start time-domain location and the end time-domain location (or cutoff time-domain location) of the antenna switching.

[0110] If the preset time-domain location for antenna switching is determined, it means that a nominal TDW containing the preset time-domain location for antenna switching will be divided into two predetermined TDWs. At this point, by combining the relationship between the predetermined TDWs and the uplink transmission time-domain location, the precise time-domain location of each predetermined TDW can be determined.

[0111] like Figure 2D As shown, this disclosure provides an information processing method, which can be executed by a UE or an access device, including:

[0112] S1410: Determine the preset time domain position for antenna switching based on the antenna switching interval and antenna switching time;

[0113] S1420: Determine the termination time domain position of the last uplink transmission before the preset time domain position as the termination time domain position of the nth predetermined TDW; and / or,

[0114] S1430: Determine the starting time domain position of the first uplink transmission after the preset time domain position as the starting time domain position of the (n+1)th predetermined TDW;

[0115] Where n is a natural number.

[0116] When an uplink antenna switch occurs once, two predetermined Time-Domain Warp Streams (TDWs) are formed before and after the preset time-domain position of the antenna switch. In this embodiment, the termination time-domain position of the last uplink transmission before the preset time-domain position, such as the termination timeslot and / or termination symbol, is used as the termination time-domain position of the previous predetermined TDW. Here, the previous predetermined TDW is referred to as the nth predetermined TDW. The nth predetermined TDW is the predetermined TDW preceding the (n+1)th predetermined TDW. When the nth predetermined TDW ends, the (n+1)th predetermined TDW begins. The starting time-domain position of the (n+1)th predetermined TDW can be based on the starting time-domain position of the first uplink transmission after the antenna switch. For example, the starting timeslot of the first uplink transmission after the antenna switch can be used as the starting timeslot of the (n+1)th predetermined TDW, and / or, the starting symbol of the first uplink transmission after the antenna switch can be used as the starting symbol of the (n+1)th predetermined TDW.

[0117] It is worth noting that any one or more of S1420 and S1430 can be implemented in combination with step S1410.

[0118] like Figure 2E As shown, this disclosure provides an information processing method, which can be executed by a UE or an access device, including:

[0119] S1510: Determine the time domain position of the predetermined TDW based on the repetition type of the uplink transmission, the time domain position of the uplink transmission, the antenna switching interval, and the antenna switching time.

[0120] Figure 1B and Figure 1C The image shows uplink transmissions with different repetition types.

[0121] When the antenna switching interval is equal to the nominal TDW and the uplink transmission repetition type is the first repetition type, the starting time domain position of the predetermined TDW is determined based on the time domain position of the uplink transmission, the length of one uplink transmission, and the antenna switching time.

[0122] The first repetition type here may include, but is not limited to, Figure 1A The uplink transmission shown, i.e., the first repetition type, may include: Figure 1BThe repetition type A is shown. When the uplink transmission repetition type is the first repetition type, uplink transmission cannot span the first time unit. However, when the uplink transmission repetition type is the second repetition type, uplink transmission can span the first time unit. Therefore, when antenna switching occurs, uplink transmissions of different repetition types may continue or stop transmitting in the first time unit where the antenna switching occurs. Since the actual time-domain position of the uplink transmission affects the time-domain position of the predetermined TDW, in the disclosed embodiment, the time-domain position of the predetermined TDW is determined based on the uplink transmission repetition type.

[0123] like Figure 2F As shown, this disclosure provides an information processing method, which can be executed by a UE or an access device, including:

[0124] S1610: Determine the first time unit in which the antenna switching occurs based on the antenna switching interval and the antenna switching time;

[0125] S1620: When the repetition type of the uplink transmission is the first repetition type, determine the starting time domain position of the predetermined TDW based on the magnitudes of N1 and N2.

[0126] N1 is the sum of N11 and N12; N11 is the number of second time units occupied by one uplink transmission; N12 is the number of second time units included in the antenna switching time; N2 is the number of second time units included in one first time unit.

[0127] In some embodiments, S1620 may include: when the repetition type of the uplink transmission is a first repetition type, determining the starting time domain position of the actual TDW based on whether the antenna switching time and the number of second time units jointly occupied by one uplink transmission in the first time unit are greater than the number of second time units contained in the first time unit, and the first time unit in which the antenna switching occurs.

[0128] For example, the first time unit is a time slot and the second time unit can be a symbol. A first time unit may include one or more second time units. A time slot may include multiple symbols. Alternatively, the first time unit may be a time slot and the second time unit may be a microtime slot. A microtime slot may include one or more symbols, and the number of symbols contained in a microtime slot is less than the number of symbols contained in a time slot. Alternatively, the first time unit may be a subframe and the second time unit may be a time slot, etc. A subframe may include multiple time slots. A time slot may include one or more microtime slots.

[0129] If the number of second time units corresponding to a transmission and an antenna switch is less than the total number of second time units contained in the first time unit, then an antenna switch will only occur in one first time unit.

[0130] If the number of second time units corresponding to a transmission and an antenna switch exceeds the total number of second time units contained in the first time unit, then the antenna switch will occur in two adjacent first time units.

[0131] If the preset time domain position of antenna switching is only distributed in one first time unit, that is, antenna switching only occupies one first time unit, then the starting time domain position of the predetermined TDW may start from that first time unit or the next first time unit.

[0132] If the preset time domain position of antenna switching is distributed in two consecutive first time units, that is, antenna switching occupies two first time units, then the starting time domain position of the predetermined TDW may start from the last time unit occupied by antenna switching, or from the first time unit after the last first time unit.

[0133] Therefore, in order to accurately determine the predetermined TDW, in this embodiment of the disclosure, the determination is made based on whether the number of second time units occupied by one uplink transmission and the total number of second time units occupied by antenna switching time exceed the number of second time units contained in one first time unit.

[0134] like Figure 2G As shown, this disclosure provides an information processing method, which can be executed by a UE or an access device, including:

[0135] S1710: When N1 is greater than N2, determine the starting time domain position of the predetermined TDW based on the starting time domain position of the uplink transmission in the next first time unit after the last first time unit where the antenna switching occurred. N1 is the sum of N11 and N12; N11 is the number of second time units occupied by one uplink transmission; N12 is the number of second units included in the antenna switching time; N2 is the number of second time units included in one first time unit.

[0136] In some embodiments, S1710 may include: when the repetition type of the uplink transmission is a first repetition type, if the number of second time units jointly occupied by the antenna switching time and one uplink transmission in the first time unit is greater than the number of second time units contained in the first time unit, determining the starting time domain position of the predetermined TDW based on the starting time domain position of the uplink transmission in the next first time unit after the last first time unit where the antenna switching occurred.

[0137] For example, if the antenna switching time and the number of second time units occupied by a first repetition type of uplink transmission in the first time unit exceed the number of second time units contained in a first time unit, then the antenna switching may span two consecutive first time units. Thus, the first time unit in the time domain where the new predetermined TDW generated by the antenna switching begins will be the next first time unit after the last first time unit occupied by that antenna switching. Furthermore, the starting second time unit in the time domain of this predetermined TDW generated by the antenna switching depends on the second time unit of the starting transmission of the next uplink transmission after the antenna switching.

[0138] For example, if antenna switching takes 1 symbol and a first repetition type uplink transmission occupies 14 symbols, then the sum of these two is greater than 14. Therefore, antenna switching will occur in the next time slot, disrupting the originally scheduled upload position of the next uplink transmission. Thus,

[0139] When the antenna switching interval is equal to the nominal TDW and the uplink transmission repetition type is the second repetition type, the starting time domain position of the predetermined TDW is determined according to the time domain position of the uplink transmission and the time domain position corresponding to the antenna switching time.

[0140] like Figure 2H As shown, this disclosure provides an information processing method, which can be executed by a UE or an access device, including:

[0141] S1810: When N1 is less than or equal to N2, determine the starting time domain position of the predetermined TDW based on the starting time domain position of the uplink transmission in the next first time unit after the first time unit in which the antenna switching occurs. N1 is the sum of N11 and N12; N11 is the number of second time units occupied by one uplink transmission; N12 is the number of second units included in the antenna switching time; N2 is the number of second time units included in one first time unit.

[0142] In some embodiments, S1810 may include: when the repetition type of the uplink transmission is a first repetition type, if the antenna switching time and the number of second time units corresponding to one uplink transmission are less than the number of second time units contained in the first time unit, determining the starting time domain position of the predetermined TDW based on the starting time domain position of the uplink transmission in the next first time unit occupied by the antenna switching.

[0143] The number of second time units corresponding to antenna switching time and one uplink transmission can be: the number of second time units corresponding to antenna switching time and one uplink transmission in the time domain, respectively.

[0144] For example, if the antenna switching time and the number of second time units occupied by a first repetition type of uplink transmission in the first time unit exceed the number of second time units contained in a first time unit, then the antenna switching may span two consecutive first time units. Thus, the first time unit in the time domain where the new predetermined TDW generated by the antenna switching begins will be the next first time unit after the last first time unit occupied by that antenna switching. Furthermore, the starting second time unit in the time domain of this predetermined TDW generated by the antenna switching depends on the second time unit of the starting transmission of the next uplink transmission after the antenna switching.

[0145] For example, if the antenna switching time is 1 symbol and the number of symbols occupied by an uplink transmission of the first repetition type is less than or equal to 13 symbols, then the sum of these two is greater than 14. In this case, the antenna switching will occur in the next time slot, and the antenna switching will not disrupt any uplink transmission. However, the phase continuity and / or power consistency of the UE will be disrupted. The time domain position of the uplink transmission in the next first time unit after the antenna switching directly determines the termination time domain position of the current predetermined TDW and the start time domain position of the next predetermined TDW.

[0146] like Figure 2I As shown, this disclosure provides an information processing method, which can be executed by a UE or an access device, including:

[0147] S1910: When the repetition type of the uplink transmission is the second repetition type, the starting time domain position of the first uplink transmission after the preset time domain position is determined as the starting time domain position of the predetermined TDW.

[0148] The second repetition type here may include, but is not limited to, those that can be used to repeat the same content. Figure 1C The uplink transmission shown. The second type of repeated transmission here can be as described above. Figure 1C The uplink transmission shown is also known as repeat type B.

[0149] A single uplink transmission of the second repetition type can span two first time units. Thus, if the antenna switching time occupies one or more second time units within the time domain of the uplink transmission, the time unit following the last second time unit occupied by the antenna switching time can continue as the subsequent transmission time unit of the uplink transmission. Therefore, the new predetermined TDW generated by the antenna switching can begin from the time unit following the last second time unit occupied by the antenna switching time.

[0150] If the antenna switching time does not occupy one or more second time units within the uplink transmission time domain position, then the starting time domain position of the next uplink transmission (i.e., the first uplink transmission) based on the preset time domain position of the antenna switching can be used as the starting time domain position of the newly generated predetermined TDW.

[0151] like Figure 2J As shown, this disclosure provides an information processing method, which can be executed by a UE or an access device, including:

[0152] S2010: When both DMRS bonding and antenna switching are enabled, determine the time domain location of the predetermined TDW based on the antenna switching interval and antenna switching time.

[0153] If both DMRS binding and antenna switching are enabled, it means that the UE may perform DMRS binding and antenna switching at the same time or at different time periods. When performing DMRS binding, a predetermined TDW needs to be determined, and uplink channel joint estimation is performed based on the determined predetermined TDW and DMRS.

[0154] At this point, the UE's antenna switching will disrupt the nominal TDW, thereby generating a new predetermined TDW. Therefore, in this situation, it is necessary to determine the time domain location of the predetermined TDW based on the nominal TDW, the antenna switching interval, and the duration of the antenna switching interval.

[0155] In other embodiments, when DMRS bonding is enabled and antenna switching is disabled, the time-domain location of the predetermined TDW can be determined based on events other than antenna switching that disrupt power consistency and / or phase continuity.

[0156] In some embodiments, when DMRS binding is not enabled and antenna switching is not enabled, it is determined that the predetermined TDW time domain location does not need to be determined.

[0157] In summary, in this embodiment of the disclosure, the timing of determining the predetermined TDW is first determined based on the nominal TDW, the antenna switching interval, and the antenna switching time, thereby reducing unnecessary determination of the predetermined TDW.

[0158] like Figure 2K As shown, this disclosure provides an information processing method, which can be executed by a UE or an access device, including:

[0159] S2110: When TDW restart is enabled, determine the time domain location of the predetermined TDW based on the antenna switching interval and the antenna switching time.

[0160] When TDW restart is enabled here, the UE and / or access device will restart the calculation of the predetermined TDW when a phase continuity and / or power consistency violation event occurs. This means a new predetermined TDW will be generated, and its time-domain location will be determined based on the location of the violation event. Antenna switching is one type of event that violates the nominal TDW; therefore, in this case, the time-domain location of the predetermined TDW will be determined based on the antenna switching interval and the antenna switching time.

[0161] In summary, in this embodiment of the disclosure, the timing of determining the predetermined TDW is first determined based on the nominal TDW, the antenna switching interval, and the antenna switching time, thereby reducing unnecessary determination of the predetermined TDW.

[0162] This disclosure provides a method for determining the actual length and / or time-domain location of a TDW when the UE performs DMRS bundling joint with antenna switching.

[0163] Specifically, it may include:

[0164] When the antenna switching interval is equal to the nominal TDW value, the length and / or time domain position of the predetermined TDW can be determined for uplink transmission of repetition type A in the following manner.

[0165] In some embodiments, the method further includes: determining the start time domain position of the predetermined TDW based on the start time domain position of the nominal TDW; and / or determining the end time domain position of the predetermined TDW based on the end time domain position of the nominal TDW.

[0166] For example, the starting time-domain position of the first predetermined TDW may be the same as the starting time-domain position of the first nominal TDW. The ending time-domain position of any nominal TDW may be the ending time-domain position of some predetermined TDWs. Some predetermined TDWs will have their ending time-domain positions determined by disruptive events and / or antenna switching, rather than continuing to the ending time-domain position of a nominal TDW.

[0167] This disclosure provides a method for determining the actual TDW, which may specifically include: flexibly determining the actual TDW based on antenna switching.

[0168] Example 1:

[0169] When the number of symbols occupied by a PUSCH in a time slot (i.e., symbol length) and the time taken for the guard period during antenna switching (i.e., guard duration) exceed the total number of symbols in a time slot including the guard period, the actual TDW count is not affected by antenna switching. For example, if the symbol length and guard period of a single PUSCH transmission do not exceed 14 symbols, the actual TDW count is not affected by antenna switching. Here, "symbol length and guard period of a single PUSCH transmission not exceeding 14" can be understood as: the sum of the symbol length and guard period of a single PUSCH transmission is less than or equal to 14 symbols.

[0170] At that time, the actual TDW count is not affected by antenna switching.

[0171] For example: The nominal TDW length is equal to 8 time slots, the repetition count is 20, and the PUSCH occupies symbol 0 to symbol 12 in one time slot. The antenna switching interval is also equal to 8 time slots, and the duration required for the antenna switching guard interval is one symbol.

[0172] Assuming frequency division duplex (FDD) is used and no other events disrupt power consistency and phase continuity occur, the actual TDW length is equal to 8 time slots. The time domain positions of the actual TDW corresponding to each repeated transmission are time slots 0 to #7, #8 to #15, and #16 to #23, etc. Antenna switching occurs on either the last two symbols of time slots #7 and #15.

[0173] Example 2:

[0174] When the number of symbols occupied by PUSCH in a time slot (i.e., symbol length, denoted by symbol length) and the time taken during the guard period occupied by antenna switching (i.e., guard duration, denoted by guard period) exceed the total number of symbols in a time slot including the guard period. For example, when the symbol length + guard period occupied by a single PUSCH transmission exceeds 14, the actual TDW count is affected by antenna switching.

[0175] For example: The nominal TDW length is equal to 8 time slots, the repetition count is 20, and the PUSCH occupies symbols 0 to 13 in one time slot. The antenna switching interval is also equal to 8 time slots, and the antenna switching guard interval is equal to 1 symbol.

[0176] Assuming FDD and no other events disrupting power consistency and phase continuity occur, the actual TDW without antenna switching would be time slots #8 to #15 and #16 to #24, etc.

[0177] If antenna switching occurs, for example, if the UE performs antenna switching on the first symbol of time slot #89, then the first symbol of time slot #8 is used as the guard interval for antenna switching. At this time, no transmission occurs on the symbol occupied by this guard interval; for example, neither uplink nor downlink transmission occurs. This is equivalent to the antenna switching occupying time slot #8, meaning time slot #8 is disrupted. Since antenna switching does not disrupt the actual TDW duration, but it does change the time domain position of the actual TDW, the UE's actual TDW is time slots 0 to #7, #9 to #16, and #18 to #26.

[0178] Method 2:

[0179] The length of the start and length indicator value (SLIV) for retransmission type A is limited to less than the maximum number of symbols contained in a time slot.

[0180] For example, the length of the SLIV corresponding to retransmission type A can be limited to less than or equal to 13, or the SLIV of retransmission type A can be limited to less than 14. Thus, when the antenna switching guard interval is 1 symbol, the sum of symbol length + guard period in a single transmission will not exceed 14. When the antenna switching guard interval is 2 symbols, the sum of symbol length + guard period in a single transmission will exceed 14.

[0181] When configuring uplink transmission, it is permissible to allow the total number of symbols occupied by the guard interval corresponding to retransmission type A and the antenna switching interval to not exceed 14.

[0182] That is, when configuring uplink transmission, the base station can configure the number of symbols and / or symbols occupied in one time slot for a retransmission of type A, based on the number of symbols occupied by the protection interval of the antenna switching interval and the premise that the number of symbols occupied by one transmission of retransmission type A and the total number of symbols occupied by the protection interval do not exceed the total number of symbols contained in one time slot.

[0183] Method 3: When the length (i.e., value) of the antenna switching interval is equal to the nominal TDW, for retransmission type B, since retransmission type B is not limited by time slots, meaning a single transmission can be performed across time slots, the number of repeated transmissions will be continuously counted within a time slot. For example, if a time slot contains 14 symbols and a single repeated transmission occupies 3 symbols, then 4 repeated transmissions can be performed within a time slot.

[0184] Since it targets retransmission type B, the actual time domain location of the TDW can be flexibly determined.

[0185] For example: Assume that the nominal TDW is equal to 8 time slots and the number of retransmissions is 20.

[0186] The time-domain resource distribution within a time slot for a single PUSCH transmission is symbols #0 to #6. The starting symbol for a single PUSCH transmission is...

[0187] The start symbol is symbol #0, and the number of consecutive symbols is 7. That is, the end symbol of a PUSCH transmission is symbol #6.

[0188] The antenna switching interval is also equal to 8 time slots, and the antenna switching protection interval is 1 symbol.

[0189] Assuming FDD and no other events disrupting power consistency and phase continuity occur, if no antenna switching is performed, the actual TDW will be time slots #0 to #7 or #8 to #15, etc.

[0190] If antenna switching is performed, symbol 0 in time slot #8 is used for the guard interval of antenna switching; this symbol can be called the guard symbol. The UE does not transmit any signals on the guard symbol. Symbol 1 in time slot #8 is re-identified as the start symbol for the 9th PUSCH repetition transmission. Symbol 1 in time slot 9 is the start position of the second actual TDW. After the guard symbol is cleared, the UE calculates the actual TDW sequentially.

[0191] Method 4:

[0192] When the length of the antenna spacing is not equal to the nominal TDW, the actual TDW is determined by both the nominal TDW and the antenna switching interval.

[0193] Here's an example illustrating the case where the antenna switching interval is longer than the nominal TDW:

[0194] Example 1: The antenna switching interval is 6 time slots long, the nominal TDW length is 4 time slots long, and for repetition type A transmission, the symbol length and guard interval occupied by one transmission do not exceed 14, then refer to... Figure 3A As shown, the three nominal TDWs are divided into four actual TDWs, corresponding to actual TDW#1, actual TDW#2, actual TDW#3, and actual TDW#4, respectively. The starting time domain positions of actual TDW#1, actual TDW#2, actual TDW#3, and actual TDW#4 are time slots #1, #5, #7, and #11, respectively. The ending time domain positions of actual TDW#1, actual TDW#2, actual TDW#3, and actual TDW#4 can be time slots #4, #6, #10, and #12, respectively.

[0195] Example 2:

[0196] This embodiment illustrates an example where the antenna switching interval length is less than the nominal TDW. Assuming the antenna switching interval length is equal to 4 time slots and the nominal TDW length is equal to 2 time slots, for repetitive type A transmissions where the symbol length of one transmission plus the guard interval of one antenna switching interval is less than or equal to 14 symbols (i.e., not exceeding the number of symbols contained in one time slot), then refer to... Figure 3B As shown, the two nominal TDWs will be divided into four actual TDWs: actual TDW#1, actual TDW#2, actual TDW#3, and actual TDW#4. The starting time domain positions of actual TDW#1, actual TDW#2, actual TDW#3, and actual TDW#4 are time slots #1, #3, #5, and #4, respectively; and the ending time domain positions are time slots #2, #4, #6, and #8, respectively.

[0197] When the antenna switching interval is less than the nominal TDW, for example, as shown in Figure 2, interval = 4, actual TDW = 2, the repetition type of this uplink transmission is repetition type A and the sum of symbol length and guard interval * (symbol length + guard period) does not exceed 14.

[0198] Example 3:

[0199] This embodiment illustrates an example where the antenna switching interval is greater than the nominal TDW.

[0200] Assuming a nominal TDW of 4 time slots and an antenna switching interval of 6 time slots, for retransmission type A where the sum of the symbol length occupied by one transmission and the number of symbols occupied by one antenna switching guard interval exceeds 14 (i.e., exceeding the number of symbols contained in one symbol), then refer to... Figure 3CAs shown, the three nominal TDWs starting from time slot #1 are switched to three actual TDWs. These three actual TDWs are actual TDW #1, actual TDW #2, and actual TDW #3, and they occupy the starting time domain positions of time slots #1, #5, and #8, respectively.

[0201] When the antenna switching interval is greater than the nominal TDW, for example:

[0202] For example, the nominal TDW can be 4 time slots, and the antenna switching interval can be 6 time slots. The uplink transmission is of repetitive type A, and the sum of the symbol length and the antenna switching time (guard period) for a single uplink transmission exceeds 14 symbols. In this case,

[0203] Example 4:

[0204] This embodiment illustrates an example where the antenna switching interval is less than the nominal TDW. Assume the nominal TDW equals 4 time slots, and the antenna switching interval is 6 time slots. For retransmission type B, the 3 nominal TDWs starting from time slot #1 will be divided into 3 actual TDWs, namely actual TDW#1, actual TDW#2, and actual TDW#3.

[0205] like Figure 3D As shown, the three nominal TDWs starting from time slot #1 are also divided into three actual TDWs, namely actual TDW #1, actual TDW #2 and actual TDW #3, and occupy the starting time domain positions of time slots #6, #6 and #7 respectively.

[0206] Figure 3E The diagram shows a PUSCH transmission of type B repetition, meaning that PUSCH transmission can restart one symbol after the duration occupied by antenna switching.

[0220] Understandably, the determining module 110 is configured to determine the starting time domain position of the predetermined TDW based on the starting time domain position of the uplink transmission in the next first time unit after the last first time unit in which the antenna switching occurred, when N1 is greater than N2.
