Abstract
Description
[0001] This application is a divisional application of patent application number 201710185413.5 (the original application was filed on March 25, 2017, and the invention was entitled "Transmission Parameter Determination Method and Apparatus"). Technical Field
[0002] This invention relates to the field of communications, and more specifically, to a method and apparatus for determining transmission parameters. Background Technology
[0003] In current discussions on NR-5G, a self-contained structure has been proposed, in which the base station sends downlink data to the terminal within a time unit (e.g., within a slot), and the terminal feeds back ACK / NACK of the downlink data in the uplink transmission domain of the same slot, thereby accelerating the data transmission cycle, especially for services with high latency requirements.
[0004] For services with high latency requirements, further research is needed on how to accelerate the demodulation speed of the receiving end.
[0005] No effective solution has yet been proposed to address the issue of slow data demodulation speed at the receiving end in related technologies.
[0006] On the other hand, many transmission parameters included in LTE do not change much dynamically. Dynamically notifying them every time would be wasteful of dynamic control signaling overhead. There is no effective solution yet for a transmission parameter notification method that can adapt to dynamic resource scheduling while saving signaling overhead. Summary of the Invention

[0189] It should be noted that the above modules can be implemented by software or hardware. For the latter, they can be implemented in the following ways, but are not limited to: all the above modules are located in the same processor; or, the above modules are located in different processors in any combination.
[0190] Example 3
[0191] In this embodiment, both the first transmission parameter set and the second transmission parameter set include the same type of information, but the time regions (i.e., the aforementioned resource regions) corresponding to the first transmission parameter set and the second transmission parameter set are different. Specifically, the time regions corresponding to the first transmission parameter set are different; for example, the first transmission parameter set corresponds to a first time region, and the second transmission parameter set corresponds to a second time region.
[0192] It should be noted that in this embodiment, the time window corresponds to the time region.
[0193] like Figures 5a-5b As shown, the second time region is a subset of the first time region, where the first time region includes {slotn5, slotn2, slotn3, slotn4}, and the second time region includes {slotn2}. Slotn5 to slotn2 can be time slots that are continuous in the time domain or discontinuous in the time domain. Figure 5a The second time region includes only one slot, but this embodiment does not exclude the possibility that the second time region may include more than one slot. Figures 5a-5b In this embodiment, the time unit is a time slot. However, this embodiment does not exclude the possibility that the time unit is a time domain symbol or other time unit. Figures 5a-5b The number of locations in the first and second time zones is just an example and does not exclude other possibilities.
[0194] The intersection between the first and second time zones can also be empty, such as... Figures 5c-5d As shown, in Figures 5c-5d The time unit is a time-domain OFDM symbol, but other time unit types are also possible.
[0195] The first and second time regions can be a non-empty intersection, and do not satisfy the subset relation, meaning the two time regions partially overlap, or they can be empty. Figure 5e As shown, Figure 5e The time unit is a slot, but other time unit types are also possible.
[0196] The first time zone and the second time zone can also be the exact same time zone.
[0197] Figures 5a-5e The relationship between the first and second time zones is just an example, and this embodiment does not exclude other time zone relationships.
[0198] Figures 5a-5b and Figure 5e As shown, in the intersection of two time regions (i.e., the part that interacts), one approach is to determine the transmission parameter values of the intersection based on the second transmission parameter set; another approach is to determine the transmission parameter values of the intersection based on both the second and second transmission parameter sets, for example, the transmission parameter values are the union of the first and second transmission parameter sets. In the non-interactive part, the transmission parameter values are based on the transmission parameters corresponding to the respective transmission region. Specifically, for example, in time units within the first time region excluding the second time region, the transmission parameter values are determined solely based on the first transmission resource set; and in time units within the second time region excluding the first time region, the transmission parameters are determined solely based on the second transmission resource set.
[0199] In this embodiment, the above-mentioned resource region is a time region. Similarly, in this embodiment, the above-mentioned resource region can be at least one of the following resource regions: time domain resource region, code domain resource region, frequency domain resource region, and spatial domain resource (antenna / beam) region.
[0200] Example 4
[0201] This embodiment describes the principles for dividing the first and second resource areas.
[0202] The first division principle is based on the time of acquiring and transmitting physical layer / MAC layer / RRC layer control information. For example, the boundary between two regions is defined by the time the terminal acquires physical layer control information (such as PDCCH) within a time unit. Figure 6a As shown, in Figure 6a The first time window (the aforementioned first resource area) is the time window before the PDCCH is decoded within a time slot, and the second time window (the aforementioned second resource area) is the time window after the PDCCH is decoded within a time slot. Figure 6a The downlink control domain can also be removed from the first time window.
[0203] In one embodiment, after a certain time point, the first transmission parameter set is updated to the previous second transmission parameter set, the start position of the first time window is updated to the start position of the previous second time window (or the end position of the previous second time window, or any position within the previous second time window), and the end position of the first time window is the second decoded control information, wherein the control information includes the aforementioned transmission parameter set or a subset thereof. Figure 6b As shown, the second resource region in slotn is the region after the PDCCH is decoded in slotn. After slotn, the starting position of the first time window is the ending position of slotn.
[0204] The second resource region division principle in this embodiment is that the MAC CE control information obtained by the terminal serves as the boundary between the first resource region and the second resource region. Preferably, the area before the aforementioned boundary is the first resource region, and the area after the aforementioned boundary is the second resource region.
[0205] The third resource area division principle in this embodiment is that the RRC control information obtained by the terminal serves as the boundary between the first resource area and the second resource area. Preferably, the area before the aforementioned boundary is the first resource area, and the area after the aforementioned boundary is the second resource area.
[0206] The fourth resource area division method in this embodiment is to determine the division of the first resource area and the second resource area based on the control information sent by the base station. The control information includes the division information of the first resource area and the second resource area. The control information is notified through at least one of the following control information: higher layer control information (such as RRC control information, MAC CE control information), and physical layer dynamic control information (such as PDCCH).
[0207] The fifth resource area partitioning method in this embodiment is based on agreed-upon rules. For example, the boundary between the first and second resource areas is defined as the Kth time-domain symbol of a slot. Alternatively, the boundary can be defined as the end position of the downlink control domain. For instance, the blind detection range of the PDCCH is the first 6 time-domain symbols of a time slot, and if the terminal detects that all DCIs in its current time unit are on the first time-domain symbol, then the second time-domain symbol serves as the boundary.
[0208] The sixth implementation in this embodiment obtains the resource region based on the time range during which the control information notifying the aforementioned transmission parameter set configuration information takes effect. Specifically, for example, the first resource region satisfies one of the following characteristics: all time units from the time the terminal receives the first configuration control information until the first configuration control information expires; a portion of time units within the range from the time the terminal receives the first configuration control information until the first configuration control information expires; all time units from the time the terminal receives the first configuration control information until the first configuration control information is updated; a portion of time units within the range from the time the terminal receives the first configuration control information until the first configuration control information is updated, such as time units within the aforementioned range that satisfy predetermined rules, such as time units within the aforementioned range that have a predetermined period, or the aforementioned time units include one of the transmission directions. The second resource region satisfies at least one of the following characteristics: all time from the time the first event occurs to the configured or agreed deadline; a group of time units consisting of a portion of time domain units within the range from the time the first event occurs to the configured or agreed deadline; all time from the time the first event occurs to the time the second event occurs; a resource group consisting of a portion of time domain unit resources within the range from the time the first event occurs to the time the second event occurs. The first event mentioned above refers to receiving control information regarding the second parameter configuration; the second event mentioned above refers to receiving control information regarding the failure or update of the second parameter configuration. Specifically, for example, the first configuration control information is higher-level configuration information, and the second parameter configuration control information is physical layer dynamic control information.
[0209] In the seventh embodiment of this example, the division of resource areas is determined according to parameter types. Different parameter types result in different divisions of resource areas.
[0210] Example 5
[0211] In this embodiment, the base station sends higher-layer control information to the terminal, wherein the higher-layer control information (i.e., the first parameter configuration control information) includes the demodulation reference signal information (i.e., the first parameter configuration) of the terminal, wherein the demodulation reference signal information includes at least one of the following: demodulation reference signal port set information, demodulation reference signal port number information, frequency domain resources corresponding to the demodulation reference signal port set, and frequency domain first precoding granularity unit corresponding to the demodulation reference signal port set.
[0212] like Figure 7a As shown, the higher-level control information corresponds to slotn~slotn+K (i.e., the first time domain range mentioned above). In the above slotn~slotn+K, the terminal can perform channel estimation based on the demodulation reference information provided in the notification.
[0213] In this way, the terminal can perform channel estimation in any slot from slot n to slot n+K before decoding its downlink control information (such as PDCCH), thereby accelerating data demodulation. For example... Figure 7b As shown, if the terminal needs to decode the downlink physical layer dynamic control information (DCI) after symbol 4, while the demodulation reference signal is sent on time domain symbol 2, the terminal can only perform channel estimation after symbol 4 if there is no higher-layer control information notification. However, if there is higher-layer control information notification, the terminal can perform channel estimation before decoding symbol 4. After decoding the DCI at symbol 4, the terminal obtains the scheduling data of this slot and can continue data demodulation using the prepared channel estimation result. When the terminal decodes the DCI and finds that there is no scheduling data of this slot, the terminal terminates the data demodulation of this slot and waits for the next slot.
[0214] As can be seen from the above description, because the high-level control information pre-configures the demodulation reference signal port information, the terminal can perform channel estimation in advance before obtaining dynamic scheduling information, thus accelerating the data processing process.
[0215] In the above scheme, when the higher layer notifies the demodulation reference signal port information, it also needs to inform the terminal of the frequency domain resources occupied by the demodulation reference signal. One method is to pre-determine the frequency domain resources occupied by the demodulation reference signal with the terminal, such as... Figure 7b As shown, the frequency domain resources occupied by the demodulation reference signal are agreed to be the system bandwidth allocated to the terminal. Of course, it is not impossible that the frequency domain resources occupied by the aforementioned demodulation reference signal are agreed to be in other cases, such as... Figure 7c As shown, the frequency domain resources occupied by the aforementioned demodulation reference signal are defined as the frequency domain resources occupied by the data most recently allocated to the terminal (i.e., the scheduling in the most recent time unit before the current time unit). The second method is to notify the aforementioned higher-layer control information of the frequency domain resources occupied by the demodulation reference signal.
[0216] exist Figures 7b-7c In this embodiment, the demodulation reference signal continuously occupies its assigned frequency domain resources. However, this embodiment does not exclude the possibility that the frequency domain resources occupied by the demodulation reference signal are physical resource blocks, and within each physical resource block, the demodulation reference signal occupies a portion of the subcarriers. For example... Figure 7d As shown, assuming the system bandwidth allocated to the terminal is 4 PRBs, and the subcarrier pattern occupied by demodulation reference signal port 1 in each PRB is as follows: Figure 7d As shown, the frequency domain resources corresponding to the demodulation reference signal are one or more of the four PRBs mentioned above. For example, the frequency domain resources corresponding to the demodulation reference signal are PRB2 to PRB3.
[0217] Before the terminal obtains dynamic DCI control information, channel estimation is first performed on demodulation reference signal port 1 on PRB2-PRB3. When the DCI control information indicates that the terminal's data is on PRB2, the terminal uses the channel estimation value obtained on PRB2 to continue data demodulation. When the DCI control information indicates that the terminal's data is on PRB1-PRB3, the terminal can use the channel estimation values already obtained on PRB2-PRB3 to demodulate the data on PRB2-PRB3, and also continue to obtain the channel estimation of demodulation reference signal port 1 on PRB1, and then perform data demodulation on PRB1. Of course, this embodiment does not exclude the possibility that the terminal's scheduling data is not on PRB2-PRB3. In this case, the terminal abandons the channel estimation values obtained on PRB2-PRB3 and performs channel estimation on the PRB where the terminal's scheduling data is located. That is, at this time, one demodulation reference signal port corresponds to two frequency domain resources: one is the frequency domain resource corresponding to the channel estimation based on the information notified by the higher-layer control information, and the other is the frequency domain resource obtained according to the dynamic control information, that is, the frequency domain resource where the demodulation reference signal is actually transmitted.
[0218] In summary, one demodulation reference signal port corresponds to two frequency domain resources. However, this embodiment does not preclude the convention that one demodulation reference signal corresponds to only one frequency domain resource, meaning that the frequency domain resource corresponding to channel estimation based on higher-layer control information notification is the same as the frequency domain resource actually transmitted by the demodulation reference signal. It is important to note that when the terminal performs channel estimation based on the information notified by the higher-layer control information, it needs to know the PRB bundling parameters because there may be some frequency domains where the terminal's data is not actually scheduled. Preferably, the frequency domain bundling of the demodulation reference signal notified by the higher-layer control information (hereinafter referred to as the first frequency domain precoding granularity unit) should be a subset of the demodulation reference signal bundling in the terminal's current time unit (hereinafter referred to as the second frequency domain precoding granularity unit), or the first precoding granularity unit is smaller than the second frequency domain precoding granularity unit. Preferably, the first frequency domain precoding granularity unit is defined as one PRB, and the bundling of the actual demodulation reference signal of the terminal in the current time unit, i.e., the second frequency domain precoding granularity unit, can be determined based on the system bandwidth allocated to the terminal, or by the size of the second frequency domain precoding granularity unit notified by control information. For example... Figure 7dAs shown, when performing channel estimation based on higher-layer control information, the terminal assumes that the size of the first frequency domain precoding granularity unit of its demodulation reference signal is one PRB. The channel estimates obtained by the terminal on PRB2 and PRB3 cannot be used for joint channel estimation. When it is known from the dynamic control information that the scheduling data of the current slot terminal occupies PRB2 to PRB3, and the second frequency domain precoding granularity unit includes two PRBs, and at this time according to the agreed rules (for example, a method similar to that in LTE can be used to divide the PRB bundling unit according to the system bandwidth), PRB2 to PRB3 fall into one PRB bundling unit. At this time, the terminal can perform joint channel estimation on the channel estimates obtained on PRB2 to PRB3.
[0219] In summary, one demodulation reference signal port corresponds to two frequency domain bundling sizes (or two frequency domain precoding granularity units). Of course, this embodiment does not exclude the possibility that the second precoding granularity unit is the same as the first precoding granularity unit, that is, one demodulation reference signal port corresponds to one frequency domain bundling size.
[0220] exist Figure 7a In this embodiment, the demodulation reference signal information of the high-level control information notification is valid from slot n to slot n+K. However, this embodiment does not exclude the possibility that the valid time units of the demodulation reference signal are discontinuous, such as... Figure 7e As shown, the demodulation reference signal is valid every K1 time units. The validity of the demodulation reference signal in these time units indicates that the terminal can perform channel estimation based on the demodulation reference signal before obtaining DCI dynamic scheduling information. During scheduling, the base station also assumes that the terminal will perform channel estimation based on the information notified by higher-layer control information in these time units before obtaining DCI scheduling information, thus providing a reference for scheduling. For example, in scheduling scenarios that do not affect MU-MIMO, data is preferentially sent to the terminal on the demodulation reference signal port notified by higher-layer control information. Figure 7a In slotn~slotn+K, or Figure 7e Slotn, slotn+K1, ..., slotn+M*K1 constitute the time region (i.e., the resource region) corresponding to the demodulation reference signal information of the aforementioned higher-level control information notification. Of course, this embodiment does not exclude the possibility that the time region corresponding to the aforementioned demodulation reference signal may be other cases.
[0221] The time region corresponding to the demodulation reference signal in the aforementioned higher-layer notification can be determined in two ways: either by agreeing on rules with the terminal, or by notifying the time region corresponding to the demodulation reference signal in the aforementioned higher-layer control information. Outside of the time region corresponding to the demodulation reference signal in the aforementioned higher-layer notification, the terminal will not attempt channel estimation based on the demodulation reference signal notified by the aforementioned higher-layer control information before acquiring dynamic control information, thereby reducing the terminal's power consumption.
[0222] In the above embodiments, the demodulation reference signal information (i.e., the first parameter configuration information or the first transmission parameter set information) is notified in the higher-layer control information. The notified demodulation reference information can be valid for more than one time unit. Of course, this embodiment also does not exclude the notification of the demodulation reference signal information (i.e., the first parameter configuration information or the first transmission parameter set information is notified in the dynamic physical layer control information) in the dynamic physical layer control information. The notified demodulation reference information is valid for more than one time unit. Alternatively, the demodulation reference information (i.e., the first parameter configuration information or the first transmission parameter set information is notified in the higher-layer control information + dynamic physical layer control information) can be notified through the higher-layer control information and the dynamic physical layer control information. The notified demodulation reference information is valid for more than one time unit.
[0223] In one implementation scenario of this embodiment, the terminal assumes that if the base station sends the demodulation reference signal port notification, it will at least send data on the frequency domain resources corresponding to the demodulation reference signal port, even if there is no terminal data on some of the corresponding frequency domain resources. For example... Figure 7d As shown, if the frequency domain resources corresponding to the demodulation reference signal port {1} notified by the terminal's higher-layer control information and / or dynamic control information are PRB0 to PRB3, then the terminal first performs the channel estimation corresponding to the demodulation reference signal port {1} on slot n on PRB0 to PRB3. If the dynamic control information indicates that the frequency domain resources occupied by the data are PRB0, the terminal assumes that although there is no terminal data on the frequency domain PRB1 to PRB3, the base station at least sends the demodulation reference signal port {1} on PRB1 to PRB3. At least the terminal can obtain some large-scale information or other information of the demodulation reference signal port {1} based on the information on PRB0 to PRB3.
[0224] In one implementation scenario of this embodiment, control information is sent to the base station, wherein the first information and the second information in the control information are jointly encoded.
[0225] The first information indicates whether the aforementioned higher-layer control information (including demodulation reference signal information) is sent to the terminal, and the second information indicates whether the terminal's downlink data acknowledgment and the downlink data occur within the same time unit.
[0226] Alternatively, the second information indicates the time offset range between the terminal's downlink data ACK / NACK response and the aforementioned downlink data, and indicates whether to send the aforementioned higher-layer control information to the terminal based on whether the time offset range is less than a predetermined value.
[0227] Alternatively, the decision to send the aforementioned higher-level control information to the terminal can be made based on the terminal's reported capability level, where the terminal's capability level characterizes the terminal's data processing capability rate level.
[0228] Similar to the demodulation reference signal information mentioned above, the transmission parameters, measurement parameters, and feedback parameters can also be notified in the aforementioned higher-level control information.
[0229] Example 6
[0230] In this embodiment, a demodulation reference signal port set is configured for the terminal using higher-layer control information and dynamic physical layer control information. The demodulation reference signal port set configured by the higher-layer control information is referred to as the first demodulation reference signal port set (i.e., the aforementioned first transmission parameter set, or first parameter configuration), and the demodulation reference signal port set configured for the terminal by the dynamic physical layer control information is referred to as the second demodulation reference signal port set (i.e., the aforementioned second transmission parameter set, or second parameter configuration).
[0231] In the first implementation of this embodiment, the demodulation reference signal port set is the union of the first demodulation reference signal port set and the second demodulation reference signal port set. For example, the demodulation reference signal port set of the terminal is configured as port {1} by the higher layer control information, and the port set configured for the terminal by the dynamic physical layer control information is {2, 3}. Then the data demodulation reference signal port set of the terminal is the union of {1} and {2, 3}, which is the set composed of demodulation reference signal ports {1, 2, 3}.
[0232] Preferably, the first demodulation reference signal port set {1} corresponds to two frequency domain resources. The first frequency domain resource is the frequency domain resource assumed to be occupied by the demodulation reference signal when the terminal performs channel estimation based on port 1 before obtaining DCI. The second frequency domain resource is the frequency domain resource of the demodulation reference signal port set {1} sent to the terminal by the base station after the terminal obtains DCI control information. The second demodulation reference signal port set corresponds to only one frequency domain resource, which is the frequency domain resource occupied by the terminal's data. In this case, one approach is to specify that the second frequency domain resource of the first demodulation reference signal port set is the corresponding frequency domain resource of the second reference signal port set. Of course, this embodiment does not exclude the possibility that the second frequency domain resource of the first demodulation reference signal port set and the corresponding frequency domain resource of the second reference signal port set are different. That is, it is allowed that the frequency domain resources corresponding to different demodulation reference signals of the terminal are different. Figure 7f As shown, the frequency domain resources corresponding to the first demodulation reference signal port set and the second demodulation reference signal port set are different. In particular, the second frequency domain resources of demodulation reference signal ports in the first demodulation reference signal port set that do not belong to the second demodulation reference port set are different from the frequency domain resources corresponding to the second reference signal port set. For example, the second frequency domain resources of demodulation reference signal ports in the first demodulation reference signal port set that do not belong to the second demodulation reference port set are conventionally defined as the aforementioned first frequency domain resources, while the frequency domain resources corresponding to the second reference signal port set are the frequency domain resources where the data of the dynamic control information scheduling resides. For example, if the first demodulation reference signal port set is {1, 5}, the second demodulation reference signal port set is {1, 2, 3}, and the demodulation reference signal for the terminal data is composed of ports {1, 2, 3, 5}, then the frequency domain resources corresponding to port {5} and the frequency domain resources corresponding to ports {1, 2, 3} can be different. This allows the terminal to correspond to different layers on different frequency domain resources.
[0233] Similarly, the relationship between the time-domain resources of the first demodulation reference signal port set and the time-domain resources of the second demodulation reference signal can also be determined using a relationship similar to that of the frequency-domain resources described above, which will not be elaborated here.
[0234] In a second implementation of this embodiment, the priority of the second demodulation reference signal port set is higher than that of the first demodulation reference signal port. The demodulation reference signal for the terminal's data and / or control is composed of the second demodulation reference signal port set. For example, if the first demodulation reference signal port set is {1} and the second demodulation reference signal port set is {2}, then the terminal's demodulation reference signal is composed of the second demodulation reference signal port set {2}. Similarly, if the first demodulation reference signal port set is {1, 2} and the second demodulation reference signal port set is {2}, then the terminal's demodulation reference signal is composed of the second demodulation reference signal port set {2}. Again, if the first demodulation reference signal port set is {1} and the second demodulation reference signal port set is {1, 2}, then the terminal's demodulation reference signal is composed of the second demodulation reference signal port set {1, 2}.
[0235] Optionally, the configurable range of the configuration information of the second demodulation reference signal is determined based on the configuration of the first demodulation reference signal. Specifically, for example, the configurable range of the configuration information of the second demodulation reference signal may be a subset of the configuration of the first demodulation reference signal, or the configurable range of the configuration information of the second demodulation reference signal may not include the configuration of the first demodulation reference signal. Of course, other methods for determining the configurable range of the second demodulation reference signal based on the configuration of the first demodulation reference signal are also possible.
[0236] Similar to the demodulation reference signal information mentioned above, the transmission parameters, measurement parameters, and feedback parameters can also be notified in the aforementioned higher-level control information and dynamic physical layer control information.
[0237] Example 7
[0238] In this embodiment, the higher-layer configuration information configures the demodulation reference information of the control channel (i.e., the first transmission parameter set or the first parameter mentioned above), wherein the information of the demodulation reference signal includes at least one of the following: demodulation reference signal port set information, pattern selection information corresponding to the demodulation reference signal port, number of demodulation reference signal ports, frequency domain resources corresponding to the demodulation reference signal port set, time domain precoding granularity unit of the demodulation reference signal, time domain symbol index information occupied by the demodulation reference signal, first frequency domain precoding granularity unit corresponding to the demodulation reference signal, third reference signal port set corresponding to the control channel demodulation reference signal, and time domain region division corresponding to the demodulation reference signal port set.
[0239] To support MU-MIMO transmission, the time-domain and / or frequency-domain regions corresponding to the aforementioned demodulation reference signal port set are designed for MU interference detection. Since control channel MU-MIMO transmission also needs to be supported, the control channel demodulation reference signal port information allocated to different terminals on the same time-frequency resources can differ. Terminals need to perform MU interference cancellation, which increases their complexity. Therefore, time-domain and / or frequency-domain restrictions can be applied to this demodulation reference signal region. Specifically, the terminal performs control channel MU interference cancellation only in the notified frequency-domain region and / or the notified time-domain region. The aforementioned third reference signal port set assists the terminal in performing MU interference cancellation. For example, if the terminal cannot assume that ports in the aforementioned third reference signal port set are not occupied by other communication nodes, then the terminal needs to perform interference estimation on the ports in the aforementioned third reference signal port set. Alternatively, the terminal can also perform MU interference cancellation on the set formed by the difference between the aforementioned third reference signal port set and the aforementioned control channel demodulation reference signal.
[0240] For a time-domain resource partitioning region corresponding to a control channel demodulation reference signal port, different regions correspond to different transmit beams, and / or different regions correspond to different receive beams. For example, if the time-domain region corresponding to a control channel demodulation reference signal port is slotn to slotn+5, it can be divided into region 1 (slotn to slotn+4) and region 2 (slot5). In this case, a region can also be called a correlation region.
[0241] The demodulation reference signal information notified by the aforementioned higher-level control information can also be sent through more than one control message. These control messages include the following information types: RRC control information, MAC CE control information, and physical layer dynamic control information.
[0242] Similar to the demodulation reference signal information mentioned above, the transmission parameters, measurement parameters, and feedback parameters can also be notified in the aforementioned higher-level control information.
[0243] Example 8
[0244] In this embodiment, the transmission parameters include one or more of the following parameters: precoding binding parameters, quasi-co-location (QCL) relationship indication parameters, resource configuration parameters, rate matching parameters, reference signal configuration parameters, receiver configuration parameters, transmission technology / mode, transmission method, mapping / interleaving parameters, transmit beam configuration parameters, modulation order configuration parameters, coding rate configuration parameters, MCS (Modulation and Coding Scheme) configuration parameters, number of codewords, number of transmission layers, multiple access method, resource multiplexing method, waveform configuration parameters, transmit power configuration parameters, numberology parameters, hybrid automatic repeat request (HARQ) related parameters, measurement parameters, and feedback parameters.
[0245] The precoding binding parameters mentioned above include at least one of the following parameters: the precoding time-domain granularity parameter (i.e., time-domain bundling granularity), the precoding frequency-domain granularity parameter (e.g., frequency-domain bundling size), the precoding region division method (e.g., whether the precoding region division is based on system bandwidth, time unit, or time-domain resources allocated to the terminal, or frequency-domain resources, as shown in Example 13 below, where the transmit beams are the same and / or the receive beams are the same in one precoding region, or the precoding region is called a related region), and whether time-domain bundling parameters are supported.
[0246] The QCL relationship indication parameters mentioned above include at least one of the following parameters: associated quasi-common reference signal information, quasi-common relationship-related grouping information, quasi-common relationship type, and channel characteristic parameters corresponding to the quasi-common relationship.
[0247] The above resource configuration parameters include at least one of the following parameters: definition of resource granularity, size of allocated resources, type of resources, time-domain resource configuration parameters, and frequency-domain resource configuration parameters; for example, the time-domain / frequency-domain resources occupied by the data allocated to the terminal, or the time-domain / frequency-domain resources corresponding to the reference signal allocated to the terminal.
[0248] The above rate matching parameters include at least one of the following parameters: time domain resources occupied by the reference signal, frequency domain resources occupied by the reference signal, start position of the data channel, end position of the data channel, area occupied by the uplink control channel, area occupied by the downlink control channel, time domain position where the data channel needs to be punched, and frequency domain position where the data channel needs to be punched.
[0249] The above-mentioned reference configuration parameters include at least one of the following parameters: density information, sequence information, number of ports, reference signal pattern information, time domain resources corresponding to the reference signal, frequency domain resources corresponding to the reference, power information, multiplexing method, OCC length, enable parameters, precoding information, port numbering rules, and reference signal type.
[0250] Specifically, if the above reference signal is a demodulation reference signal DMRS, the configuration information of the demodulation reference signal includes: density, sequence, number of ports, pattern, power, multiplexing method, OCC length, time domain symbol of the demodulation reference signal, and bundling region of the demodulation reference signal.
[0251] When the above reference signal is the phase compensation reference signal PTRS, the following information can be notified: number of ports, sequence, time-frequency density, enable parameters, position, power, and precoding.
[0252] When the aforementioned reference signal is a measurement reference signal (CSI-RS reference signal or SRS), at least one of the following information can be provided: pattern, density, OCC, sequence, power, multiplexing method, numbering rule, and type (CSI-RS type can be distinguished by at least one of the following characteristics: full-bandwidth transmission or partial-bandwidth transmission; whether the aforementioned measurement reference signal is used for beam management or for channel quality acquisition; whether the number of time-domain repetitions of the aforementioned measurement reference signal in one period is greater than a predetermined threshold or equal to or less than a predetermined threshold; whether the time-domain symbol containing the aforementioned measurement reference signal contains only the measurement reference signal or whether the time-domain symbol containing the aforementioned measurement reference signal contains signals other than the measurement reference signal; whether the time-domain signal of the aforementioned measurement reference signal has a repeating pattern or not; whether the aforementioned measurement reference signal is transmitted using IFDMA or by increasing the subcarrier spacing; whether the aforementioned measurement reference signal resource has a corresponding quasi-co-location reference signal or not.
[0253] The above-mentioned reception configuration parameters include at least one of the following parameters: reception beam, reception precoding weights, reception antenna, and quasi-common reference signal information corresponding to the above-mentioned reception method.
[0254] The above transmission configuration parameters include at least one of the following parameters: transmission beam, transmission precoding weights, transmission antenna, and quasi-common reference signal information corresponding to the above transmission method.
[0255] The aforementioned transmission technology parameters include at least one of the following: diversity, open loop, semi-open loop, closed loop, and precoded polling.
[0256] The transmission method parameters mentioned above include at least one of the following: single-beam transmission, multi-beam transmission, single TP / Cell, multiple TP / Cell, SU / MU, single-layer / multi-layer, or other transmission technologies.
[0257] The above-mentioned transmit power configuration parameters include at least one of the following parameters: absolute power, relative power offset, and relative power reference object;
[0258] The above Numerology parameters include at least one of the following parameters: subcarrier spacing, time-domain symbol length, and CP length.
[0259] HARQ-related parameters include at least one of the following: process ID, NDI (New data indication), redundancy version RV, and number of processes.
[0260] The above measurement parameters include measurement period, measurement constraints, interference measurement reference signal, time domain resources where the measurement reference signal is located, frequency domain resources where the measurement reference signal is located, and type of measurement reference signal.
[0261] The reporting parameters include: reporting type, time domain resources occupied by the reported information, frequency domain resources where the reported information is located, the transmitting beam used for the reporting information, and the receiving beam information corresponding to the reporting resources.
[0262] For the configuration method of the aforementioned transmission parameter type, the first configuration method is that the transmission parameter type information is included in the aforementioned M transmission parameter sets. Each transmission parameter set includes one configuration of the aforementioned transmission parameter type, and each transmission parameter set corresponds to a resource region (e.g., a time region), where M is a natural number greater than 1. In the intersection of the M resource regions, the configuration value of the aforementioned transmission parameter type is jointly determined by multiple transmission parameter sets from the aforementioned M transmission parameter sets (e.g., by the union of the multiple transmission parameter sets), or the configuration value of the aforementioned transmission parameter is determined by one of the aforementioned M transmission parameter sets (e.g., by the transmission parameter set with higher priority). In the part where a resource region acts independently (the independent part of a resource region, i.e., the part of the resource region that does not intersect with any other resource region among the aforementioned M resource regions), the configuration value of the aforementioned transmission parameter is determined by the transmission parameter set corresponding to the aforementioned resource region. For example, if M=2, the first transmission parameter set is notified by higher-layer control information, and the second transmission parameter set is notified by physical layer dynamic control information. The aforementioned first transmission parameter set can also be notified or agreed upon through one of the following methods: notification by system message, notification by previous physical layer dynamic control information, or reservation of the aforementioned first transmission parameter set by the base station and the transmitting end.
[0263] Optionally, in the resource region corresponding to the intersection of the second resource region and the first resource region before obtaining the second transmission parameter set, signals are first transmitted or received using the first transmission parameters. After obtaining the second transmission parameter set, the processing method for the intersection region described above is used to determine the configuration value of the transmission parameters from the union of the M transmission parameter sets, or from one of the M transmission parameter sets. Signal transmission and reception are then performed according to the configuration value of the transmission parameters. Figure 7b As shown, the first set of transmission parameters is notified by higher-layer control information, and its corresponding resource area includes slot n. The second set of transmission parameters is notified by dynamic physical layer control information, and its area of application also includes slot n. However, before the dynamic physical layer control information is decoded, the dynamic physical layer control information has not yet been obtained in the time domain symbols (corresponding to the time domain symbols before time domain symbol 4 in slot n, or the time domain symbols before the time domain symbols in slot n excluding the downlink control area). At this time, the received signal is first estimated and / or demodulated using the transmission parameter information notified by the higher-layer control information. After the dynamic physical layer control information is obtained, the configuration values of the transmission parameters in the area before time domain symbol 4 are determined according to the configuration values of the transmission parameters notified in the dynamic physical layer control information, or according to the configuration values of the transmission parameters notified by the dynamic physical layer control information and the configuration values of the transmission parameters in the higher-layer control information.
[0264] In one embodiment of this example, M=3, the first set of transmission parameters is notified by RRC control information, the second set of transmission parameters is notified by MAC-CE control information, and the third set of transmission parameters is notified by physical layer dynamic control information.
[0265] The second method for configuring the aforementioned transmission parameters involves determining the number of parameter configurations corresponding to the parameter type based on the parameter type or indication information. For example, if the parameter configuration is determined to be one, the configuration value of the parameter is determined based on the first parameter configuration, which is then notified in a control message. When the parameter configuration is determined to be greater than one, there are X parameter configurations for the aforementioned parameter type, each containing a configuration value for that parameter type. Each parameter configuration corresponds to a time region, similar to the method described above for determining parameter configurations based on M sets of transmission parameters. In the intersection of the multiple time regions, the configuration value of the aforementioned parameter type is determined jointly based on multiple parameter configurations among the X parameter configurations, or based on one of the X parameter configurations (e.g., based on the parameter configuration with higher priority). In the separate action portion of a time region (separate action means there is no intersection between the aforementioned time region and any of the other X time regions), the transmission parameter configuration value is determined based on the parameter configuration corresponding to the aforementioned time region. For example, the configuration of X parameters can be controlled by RRC control information and dynamic physical layer control information, or the configuration of X parameters can be notified by the first RRC control information and the second control information.
[0266] The priority of the above-mentioned set of transmission parameters (or the above-mentioned parameter configuration) can be determined in the following way:
[0267] The later the control information for the aforementioned set of transmission parameters is notified, the higher the priority of the aforementioned set of transmission parameters.
[0268] The priority of the aforementioned transmission parameter set is determined based on the indication information, wherein the indication information includes the priority information of the aforementioned transmission parameter set.
[0269] Example 9
[0270] In this embodiment, the control channel demodulation reference information (i.e., the aforementioned transmission parameter set or the aforementioned parameter configuration information) is configured through multi-level control information, wherein the set of control channel demodulation reference ports notified by the lower-level control information is a subset of the set of control information ports notified by the higher-level control information.
[0271] In this embodiment, the levels of the aforementioned RRC control information, MAC CE control information, and physical layer dynamic control information decrease sequentially.
[0272] For example, a first set of demodulation reference signal ports can be configured for the terminal's control channel demodulation reference signal via RRC control information, and a second set of ports can be configured for the terminal's control channel demodulation reference signal via MAC CE. The second set of ports is a subset of the first set of ports, or the MAC CE control information may contain a selection from the first set of ports. This example also does not exclude the possibility that physical layer dynamic control information selects from the demodulation reference signal port set configured by the MAC CE, and that the selected demodulation reference signal port serves as the terminal's subsequent control channel demodulation reference signal port, or as the demodulation reference signal port for the second control information in this time unit. Figure 8 As shown, in one time unit, the first control information indicates the demodulation reference signal port information of the second control information. Figure 8 The first control information and the second control information are frequency-division multiplexing. Of course, this embodiment does not exclude the possibility that the first control information and the second control information are time-division multiplexing and / or frequency-division multiplexing.
[0273] Similarly, the above transmission parameters can also be configured through multi-level control information.
[0274] Example 10
[0275] In this embodiment, the high-level control information configuration transmission parameter information (the aforementioned first parameter configuration) corresponds to a time transmission region, such as corresponding to... Figures 5a-5e The first time window in the process.
[0276] The terminal performs the following information processing steps one and two:
[0277] Step 1: In each time unit included in the first time window, the terminal performs signal reception, and / or channel estimation, and / or data equalization, and / or channel decoding based on the transmission parameters notified by higher-layer control information. It also detects dynamic physical layer control information.
[0278] Step Two:
[0279] If no dynamic physical layer control information is detected in the aforementioned time unit (or no dynamic physical layer control information for the channel or signal is detected, wherein the aforementioned transmission parameters are transmission parameters for the aforementioned channel or signal), the aforementioned higher layer control information is used as the configuration value of the transmission parameters for information processing.
[0280] If physical layer dynamic control information is detected after the nth time domain symbol in the aforementioned time unit (n is an integer, and the time domain symbols of the aforementioned time unit are numbered from 0), and the aforementioned dynamic control information also includes configuration values of the same type of transmission parameters notified in the higher layer control information, then the value of the aforementioned transmission parameter is determined according to the dynamic control information, or the configuration value of the aforementioned transmission parameter is determined jointly according to the dynamic control information and the higher layer control information, and information processing is performed according to the determined configuration value.
[0281] Alternatively, step two is:
[0282] If no dynamic physical layer control information is detected in the above time unit, discard the information processing results already obtained and wait for the next time unit.
[0283] If physical layer dynamic control information is detected after the nth time domain symbol in the aforementioned time unit (n is an integer, and the time domain symbols of the aforementioned time unit are numbered from 0), and the aforementioned dynamic control information also includes the configuration value of the transmission parameters notified in the higher layer control information, then the value of the aforementioned transmission parameters is determined based on the dynamic control information, or the configuration value of the aforementioned transmission parameters is determined jointly based on the dynamic control information and the higher layer control information.
[0284] Alternatively, step two is:
[0285] If no dynamic physical layer control information is detected in the above time unit, discard the data processing results already obtained.
[0286] If physical layer dynamic control information is detected after the nth time domain symbol in the above time unit (n is an integer, and the time domain symbols of the above time unit are numbered from 0), the dynamic control information indicates whether there is a terminal signal / channel (e.g., whether there is terminal scheduling data or whether there is terminal measurement reference signal). If there is terminal scheduling data, the subsequent processing of information continues according to the information processing results obtained in step one. If there is no terminal scheduling signal / channel, the information processing results obtained in step one are discarded.
[0287] The above describes the processing of information, including the processing of data channels, measurement reference signals, or uplink control channels.
[0288] Example 11
[0289] In this embodiment, the terminal corresponds to multiple demodulation reference signal port sets (the aforementioned reference signal resource areas), and each demodulation reference signal port set has a different frequency domain bundling (the aforementioned transmission parameters).
[0290] One implementation of different frequency domain bundling is to use different frequency domain bundling sizes. For example, the frequency domain bundling size of the first demodulation reference signal port set is 2 PRBs, and the frequency domain bundling size of the second demodulation reference signal port set is 4 PRBs. Preferably, the smaller frequency domain bundling region falls within the larger frequency domain bundling region, such as... Figure 9 As shown.
[0291] The second implementation differs in frequency domain bundling. The frequency domain bundling size is the same, but the frequency domain bundling regions are divided differently, such as... Figure 10 As shown.
[0292] The base station notifies the terminal of the frequency domain bundling information corresponding to each demodulation reference signal port set. Alternatively, the base station notifies the terminal of the frequency domain bundling information corresponding to some demodulation reference signal port sets, while the frequency domain bundling information corresponding to other demodulation reference signal port sets is obtained according to agreed rules.
[0293] The demodulation reference signal for the data and / or control of the aforementioned terminal is formed by the union of the first demodulation reference signal port set and the second demodulation reference signal port set. Alternatively, there may be a priority among the different demodulation reference signal port sets corresponding to the terminal.
[0294] In the aforementioned frequency domain bundling region, the transmitted beam of the aforementioned signal remains unchanged, and / or the received beam of the aforementioned signal remains unchanged.
[0295] Similarly, the terminal corresponds to multiple demodulation reference signal port sets, each with a different time-domain bundling. The base station notifies the terminal of the time-domain bundling information corresponding to each demodulation reference signal port set, which will not be elaborated here.
[0296] Example 12
[0297] In this embodiment, the terminal corresponds to multiple demodulation reference signal port sets (the resource areas mentioned above), and the frequency domain resources (the transmission parameters mentioned above) corresponding to each demodulation reference signal port set are different.
[0298] The frequency domain resources corresponding to the aforementioned demodulation reference signals are different. In the first embodiment, this means that the frequency domain resources occupied by the data corresponding to different demodulation reference signals are different. The frequency domain resources occupied by one demodulation reference signal port are the frequency domain resources occupied by the data corresponding to the aforementioned demodulation reference signal port. For example, if the frequency domain of demodulation reference signal port 1 corresponds to PRB0 to PRB3, then the frequency domain resources occupied by the data corresponding to demodulation reference signal port 1 are also PRB0 to PRB3. Figure 11 As shown.
[0299] The frequency domain resources corresponding to the aforementioned demodulation reference signals are different. In the second embodiment, this means that the first frequency domain resources corresponding to different demodulation reference signals are different, and the first frequency domain resources corresponding to one of the demodulation reference signals are different from the frequency domain resources occupied by the data of the aforementioned demodulation reference signal. For example, the first frequency domain resources corresponding to a demodulation reference signal are configured by a higher layer, and the frequency domain resources occupied by the data corresponding to the aforementioned demodulation reference signal are a subset of the aforementioned first frequency domain resources. And / or the aforementioned first frequency domain resources can be the smallest frequency domain unit transmitted by the aforementioned demodulation reference signal, or the aforementioned first frequency domain resources can be the largest frequency domain resources transmitted by the aforementioned demodulation reference signal.
[0300] Example 13
[0301] In LTE, the division of frequency domain bundling areas is determined based on system bandwidth and is basically cell-specific. For example, if the frequency domain bundling is 2 PRBs and the system has 50 available PRBs, then starting from the lowest frequency domain PRB0, every 2 PRBs constitute a PRB Bundling area.
[0302] In NR, since the system bandwidth seen by the base station and the system bandwidth seen by the terminal can be different, the system bandwidth can be allocated in a UE-specific manner. In this case, the division of the PRB Bundling area needs to be further considered.
[0303] The first approach in this embodiment is to perform PRB Bundling region division based on the lowest frequency domain of the system bandwidth seen by the terminal, rather than performing PRB Bundling region division based on the system bandwidth on the base station side. Figure 12 As shown, the system bandwidth on the base station side and the system bandwidth on the terminal side are different. Preferably, when allocating system bandwidth to the terminal, the boundary of the system bandwidth should coincide with the boundary of the PRB Bundling region division based on the base station side. This ensures that the boundaries between the PRB Bundling region obtained from the base station side system bandwidth and the PRB Bundling region obtained from the terminal side system bandwidth are consistent, preventing situations like... Figure 13 As shown, different terminals with the same bundle size may have different regional divisions.
[0304] The second method in this embodiment is to perform PRBBundling region division based on the resources allocated to the terminal in the current time unit, such as... Figure 14As shown, the resources allocated to the terminal in the current time unit are {PRB0, PRB3, PRB5, PRB6}. When the PRB Bundling includes two PRBs, then {PRB0, PRB3} constitutes one PRB Bundling region, and {PRB5, PRB6} constitutes another PRB Bundling region. Of course, there can be further restrictions on the division of PRB Bundling regions based on the resources allocated to the terminal in the current time unit. For example, if the interval between two allocated resources is greater than the PRB Bundling size, they are not divided into the same PRB Bundling region. Figure 14 As shown, this forms three PRB Bundling regions: {PRB0}, {PRB3}, and {PRB5~6}.
[0305] Example 14
[0306] The frequency domain units of the above signal are determined according to the number of time domain symbols occupied by the above signal, wherein the frequency domain units of the above signal include at least one of the following units: the frequency domain scheduling unit corresponding to the above signal; the precoding frequency domain unit corresponding to the above signal.
[0307] The length of the aforementioned time-domain symbols satisfies at least one of the following characteristics: the number of the aforementioned time-domain symbols is the number of the first reference time-domain symbols corresponding to the aforementioned signal; the number of the aforementioned time-domain symbols is the number of the aforementioned signal corresponding to the aforementioned signal; or the number of the aforementioned time-domain symbols is the number of the first time units corresponding to the aforementioned signal. For example, if the subcarrier spacing corresponding to the aforementioned demodulation reference signal is 60kHz, then the number of time-domain symbols occupied by the aforementioned signal is the number of time-domain symbols with a subcarrier spacing of 60kHz, and the number of the aforementioned first reference time-domain symbols is the number of time-domain symbols with a subcarrier spacing of not 60kHz. For example, if the first reference time-domain symbols are the number of time-domain symbols with a subcarrier spacing of 15kHz, then one 15kHz time-domain symbol corresponds to one 60kHz time-domain symbol, for example, one 15kHz time-domain symbol corresponds to four 60kHz time-domain symbols.
[0308] The fewer time-domain symbols the aforementioned signal occupies, the larger the aforementioned frequency-domain unit. For example, Table 1 shows the relationship between the aforementioned frequency-domain units and the number of time-domain symbols.
[0309] Table 1
[0310]
[0311] The aforementioned frequency domain unit can be further determined by combining at least one of the following information: the size of the frequency domain resources occupied by the current terminal's data, the size of the data transmission block of the aforementioned terminal, and the carrier frequency location of the aforementioned communication.
[0312] Of course, this embodiment does not exclude other correspondences between the frequency domain units and the number of time domain symbols, such as the relationship that the fewer the number of time domain symbols, the smaller the frequency domain units. Or there may be a relationship between the number of time domain symbols and the frequency domain units, but it is not a monotonic relationship. The monotonic relationship can be a regional monotonic relationship as shown in Table 1. For example, the frequency domain units corresponding to the number of time domain symbols of 3 to 4 are 4. In this case, the monotonic relationship is not satisfied (the number of time domain symbols does not determine the size of the frequency domain units). However, there is a monotonic relationship between the time domain symbol number region of 3 to 4 and the time domain symbol number region of 5 to 7, that is, the larger the number of time domain symbols, the smaller the corresponding frequency domain units.
[0313] The method described above in this embodiment can be similarly used to determine the time-domain unit of the signal based on the size of the frequency-domain resources occupied by the signal, wherein the time-domain unit of the signal includes at least one of the following units: the time-domain scheduling unit corresponding to the signal; and the precoding time-domain unit corresponding to the signal, which will not be elaborated here.
[0314] Example 15
[0315] In this embodiment, the base station performs joint encoding notification of the frequency domain resource information and time domain resource information of the above signal in a control information notification domain.
[0316] Joint coding can save control information overhead. For example, if a frequency domain resource is notified separately, it requires 3 bits. If a time domain resource is notified separately, such as the start symbol position and / or end symbol position of the time domain resource, it requires 2 bits. However, if joint coding can eliminate some unnecessary notification cases, the above information can be notified with only 4 bits. Of course, this embodiment does not exclude the possibility that the number of notification bits in joint coding is the same as the sum of the number of bits in separate notifications. However, there are cases where the number of notification bits in joint coding is less than the sum of the number of bits in separate notifications. Therefore, overall, it can save control information overhead.
[0317] Example 16
[0318] In this embodiment, the number of notification bits for frequency domain resources is determined based on the number of time domain symbols corresponding to the above signal, or based on the number of time domain symbols occupied by the transmission domain with the same transmission direction as the above signal in a time unit.
[0319] For example, the first control information notifies the terminal of the number of time-domain symbols occupied by the signal, and / or the position of the time-domain symbols occupied by the terminal's signal. The second control information notifies the terminal of the number of bits in the frequency-domain resource domain of the signal, which is determined based on the aforementioned number of time-domain symbols occupied by the signal. Preferably, the first control information is higher-layer control information, and the second control information is physical-layer dynamic control information; however, it is not excluded that both are physical-layer dynamic control information.
[0320] Alternatively, the first control information may indicate the number of time-domain symbols occupied by the transmission domain in the same direction as the signal transmission of the aforementioned terminal within the current time unit, such as the number of time-domain symbols occupied by the downlink transmission domain in the current time unit, and / or the position of the time-domain symbols occupied by the downlink transmission domain signal. The second control information may indicate the number of bits in the frequency domain resource domain occupied by the downlink data, determined based on the number of time-domain symbols occupied by the downlink transmission domain in the aforementioned time unit. Preferably, the first control information is common control information, and the second control information is proprietary control information. In this case, the number of time-domain symbols in the downlink transmission domain may include the downlink control domain or may not include the downlink control domain.
[0321] The method described above in this embodiment can be similarly used to determine the number of notification bits for time-domain resources based on the size of the frequency-domain resources corresponding to the signal, or based on the size of the frequency-domain bandwidth allocated to the terminal, which will not be elaborated here.
[0322] Example 17
[0323] In this embodiment, the transmission parameters of the periodically transmitted measurement reference signal or the half-periodly transmitted measurement reference signal (such as SRS, CSI-RS) reference signal are in the higher-level control information (the aforementioned first parameter configuration information).
[0324] The same type of parameters mentioned above will also be notified in the physical layer dynamic control information, enabling adaptation to dynamic resource scheduling.
[0325] In time units without dynamic control information, the values of the aforementioned parameter types are determined solely based on higher-layer control information. When dynamic control information is available, the values of the aforementioned parameter types are determined based on dynamic physical layer control information. For example, the aforementioned transmission parameters include the time-domain resources occupied by the aforementioned parameter signals and the frequency-domain resources occupied by the aforementioned reference signals. When the time-domain resources and / or frequency-domain resources (time-domain resources or frequency-domain resources obtained from the configuration of the first parameter) occupied by the measurement reference signal in a time unit cannot be used for the aforementioned measurement reference signal, dynamic signaling is required to inform the terminal of this information.
[0326] For example, if the time / frequency domain resources occupied by the measurement reference signal on slot n, as notified by the higher layer, are occupied by other signals or channels, the base station informs the terminal of this information in the dynamic control information on slot n. If the aforementioned measurement reference signal is an SRS measurement reference signal, the terminal cannot send SRS on this slot, or it can send only a portion of the SRS (the portion not occupied by other signals or channels). Alternatively, the control information may inform the terminal of a new time / frequency domain position for the aforementioned measurement reference signal on slot n (i.e., the aforementioned second parameter configuration), and the SRS will be sent at this new time / frequency domain position. Depending on the new time / frequency domain position obtained, in the next cycle, one approach is to use the first parameter configuration, and another is to use the second parameter configuration; that is, after slot n, the first parameter configuration is updated to the second parameter configuration.
[0327] When the aforementioned measurement reference signal is an SRS measurement reference signal, the base station can send control information on slotn, or send the aforementioned control information after slotn, so that the terminal knows that the aforementioned measurement reference signal on slotn has changed the time domain / frequency domain resources, or that the aforementioned measurement reference signal was not sent on slotn, or that only part of the measurement reference signal was sent on slotn, or that the aforementioned measurement reference signal was not sent on slotn and was moved to slotn+k to send the measurement reference signal.
[0328] Furthermore, the control information can indicate or specify whether the terminal needs to detect the dynamic control information to determine the time domain and / or frequency domain location of the aforementioned measurement reference signal. That is, whether the parameter type of the terminal needs to determine the time domain and / or frequency domain location of the aforementioned measurement reference signal has only one parameter configuration or two parameter configurations.
[0329] Example 18
[0330] In this embodiment, parameters of the same type are configured in both the higher-level control information and the physical layer dynamic control information. Alternatively, they may be configured in both the RRC control information and the MAC-CE control information, or both the MAC-CE control information and the physical layer dynamic control information.
[0331] Example 19
[0332] In this embodiment, parameters of the same type are configured in the high-level control information, the MAC-CE control information, and the physical layer dynamic control information.
[0333] Example 20
[0334] In this embodiment, for parameters of the same type, one set of transmission parameters corresponds to multiple subsets, and each subset of transmission parameters corresponds to a configuration value of the above-mentioned type of parameter.
[0335] Specifically, for example, the configuration values of the aforementioned transmission parameters corresponding to each subset and a virtual transmission cell.
[0336] For example, in a time unit, the terminal is allocated three frequency domain resources (corresponding to three virtual cells respectively). Each frequency domain resource has its own independent configuration (such as MCS, DMRS) and other related information for the corresponding transmission parameters. Of course, some transmission parameters on these three frequency domain resources can be the same (such as NDI, RV, etc.).
[0337] Alternatively, a transmission parameter set may consist of multiple subsets representing different configurations of the same transmission parameter set. For example, a higher layer might configure a first transmission parameter set, which includes two types of parameters: {frequency domain resources, MCS, DMRS}. This first transmission parameter set could contain three subsets, such as {{frequency domain resource 1, MCS1, DMRS1}, {frequency domain resource 1, MCS2, DMRS2}, and {frequency domain resource 3, MCS3, DMRS3}}. Here, MCS1 to MCS3 represent the configuration values of the three MCS values, and similarly, DMRS1 to DMRS3 represent the configuration values of the three DMRS (demodulation reference signal). Frequency domain resources 1 to 3 correspond to the allocation values of the three frequency domain resources. The physical layer dynamic control information notifies the second transmission parameter set, which includes three sets: {{frequency domain resource d1, MCSd1, DMRSd1}. {Frequency domain resources d1, MCSd2, DMRSd2}, {Frequency domain resources d3, MCSd3, DMRSd3}}, where MCSd1 to MCSd3 represent the configuration values of 3 MCSs, and similarly, DMRSd1 to DMRSd3 represent the configuration values of 3 DMRSs (demodulation reference signals). Frequency domain resources d1 to d3 correspond to the allocation values of 3 frequency domain resources.
[0338] In the above embodiments, the first transmission parameter set and the second transmission parameter set include the same number of subsets. This embodiment does not exclude the possibility that the two sets include different numbers of subsets.
[0339] Example 21
[0340] In this embodiment, the same type of transmission parameters correspond to multiple parameter configurations, and different parameter configurations correspond to different frequency domain resources.
[0341] For example, the OCC length information of a demodulation reference signal, as mentioned above, varies in different frequency domain resources. This allows for different numbers of MU users or layers to correspond to different frequency domain resources in the same time unit.
[0342] For example, the above transmission parameters may correspond to different sets of demodulation reference signal ports for MU interference cancellation based on a demodulation reference signal. This allows for different numbers of MU users or layers corresponding to different frequency domain resources in the same time unit.
[0343] For example, the above transmission parameters are RI information, which allows different number of layers to correspond to different frequency domain resources;
[0344] For example, the above transmission parameters are MCS information, which allows different frequency domain resources to correspond to different MCS;
[0345] The above transmission parameters can be one or more of the transmission parameters described in Example 8.
[0346] Example 22
[0347] In this embodiment, the first resource region changes according to the second resource region. For example, if the first transmission parameter set (or first parameter configuration) is configured by a higher layer, the first time region corresponding to the aforementioned first transmission parameters is... Figure 5a or Figure 5b In one of the first time windows, the aforementioned second transmission parameters are dynamically controlled and notified at the physical layer, and the second transmission parameters correspond to the second time region. Figure 5a or Figure 5b In one of the time windows, for example, before slot n1, the first time window is {slot n1, slot n2, slot n3, slot n4}, and in slot n2, the first time window is {slot n1, slot n3, slot n4}. If the transmitted parameter is a measurement reference signal parameter, then the first time window includes time units excluding the time unit containing the second time window.
[0348] Example 23
[0349] In this embodiment, the first transmission parameter is notified in the higher-level control information, and the first transmission parameter is notified in the dynamic control information (which corresponds to...). Figure 5a or Figure 5b (in the middle), where the dynamic control information further indicates whether there is information update for the same type of parameter in the dynamic control information.
[0350] For example, the aforementioned transmission parameters represent the time-domain start position of the data channel allocated to the terminal. The higher-layer control information indicates that it starts from the second time domain. The dynamic control information indicates whether to maintain the original state. If the indication is to maintain the original state, the terminal's data starts from the second symbol notified by the higher layer. When the indication changes to a new state, the dynamic control information further indicates the starting position of the data, or the offset between the starting position of the data and the starting position of the higher layer.
[0351] For example, the aforementioned transmission parameters represent the frequency domain resources allocated to the data channel of the terminal. The first dynamic control information indicates whether the aforementioned frequency domain resources have changed. If they remain unchanged, the frequency domain resources of the terminal in the current time unit are indicated by the higher-layer control information. If they need to be changed, the second dynamic control information further indicates the new frequency domain resources.
[0352] Alternatively, the number of bits required for physical layer dynamic information can be determined based on whether the aforementioned transmission parameters have changed.
[0353] Example 24
[0354] In this embodiment, multiple sets of transmission parameters are notified in the higher-layer control information, and the physical layer dynamic control information selects one of the multiple sets of transmission parameters.
[0355] The aforementioned transmission parameters can be any one of those in Example 8.
[0356] The above set of transmission parameters includes one or more transmission parameter types, and each transmission parameter is combined.
[0357] For example, the higher-level configuration might be as follows: demodulation reference signal port set {1, 2, 3}, {2, 3, 4}, {5, 6}. This is the demodulation reference signal set corresponding to the current data channel in the physical layer dynamic control information.
[0358] Alternatively, the aforementioned set of demodulation reference signal ports configured at higher levels may be the set of demodulation reference signal ports used by the terminal for MU interference cancellation. For example, the terminal cannot assume that the ports in the aforementioned set of reference signal ports are not occupied by other users. It cannot assume that the ports in the aforementioned set of reference signal ports, excluding those corresponding to the terminal's data channel, are not occupied by other users.
[0359] Example 25
[0360] In this embodiment, the higher layer configures a first transmission parameter set information, wherein the transmission parameter set includes the following eleven parameter types:
[0361] Carrier frequency indication information, downlink data channel time-frequency resource allocation indication information, uplink power configuration parameters, uplink control channel time-domain / frequency-domain correlation indication information, HARQ process number, antenna port / sequence scrambling information / layer number joint indication information, uplink measurement reference signal request information, MCS, NDI, RV indication information, PQI indication information (PDSCH RE Mapping and Quasi-Co-Location Indicator).
[0362] In each time unit covered by the higher-layer control information (the time unit covered by the higher-layer control information can also be further defined), the terminal first performs channel estimation, equalization demodulation, and data processing based on the information configured by the higher layer. If the terminal obtains dynamic physical layer control information corresponding to a downlink data channel in the 4th time domain symbol of the current time unit, it abandons the data processing results it has already obtained.
[0363] When dynamic physical layer control information corresponding to downlink data of this terminal in the current time unit is obtained, the dynamic physical layer control information specifically indicates the parameter type that needs to be updated among the above eleven types of parameters. For example, if the notification is type 5 out of the eleven types, the dynamic physical layer control information further indicates the update value of the five types of parameter that need to be updated, or the relative value of the update parameter relative to the higher layer notification parameter.
[0364] Example 26
[0365] In this embodiment, the first resource area corresponding to the aforementioned high-level control information is as follows: Figure 5a The first time window in the dynamic physical layer control information corresponds to the second resource region, such as... Figure 5a The second time window in the process. The higher-layer control information (where the parameter value being notified is the first transmission parameter mentioned above) and the dynamic physical layer control information (where the parameter value being notified is the second transmission parameter mentioned above) include parameters of the same type. For example, information related to transmitting beams or information related to receiving beams.
[0366] In the first method, after slotn2 (slotn2 is the time unit where the dynamic physical control information is located), the first transmission parameter mentioned above is still the value of the higher layer notification, that is, in slotn3, the data is first processed using the beam 1 of the higher layer notification.
[0367] In the second approach, after slotn2 (where the dynamic physical control information resides in time unit), the aforementioned first transmission parameter is updated to the second transmission parameter value. That is, in slotn3, data processing is first performed using beam 2, which is notified from higher layers.
[0368] In this embodiment, it is assumed that the beam for higher-level control information notification before slotn1 is 1, and slotn2...
[0369] The beam for sending dynamic physical layer notifications is beam 2.
[0370] Example 27
[0371] In this implementation, P demodulation reference signal port sets are configured for the terminal, where P is a natural number greater than 1. Each of the P demodulation reference signal port sets has at least one of the following pieces of information:
[0372] The third demodulation reference signal set corresponding to the above set; the frequency domain resources corresponding to the above set; the time domain cell pattern information corresponding to the above set;
[0373] The frequency domain precoding granularity units corresponding to the above set;
[0374] The temporal precoding granularity units corresponding to the above set;
[0375] Configure at least one of the following information for each of the P demodulation reference signal port sets mentioned above:
[0376] The third demodulation reference signal set corresponding to the above set;
[0377] The frequency domain resources corresponding to the above set;
[0378] The time-domain unit pattern information corresponding to the above set; the frequency-domain precoding granularity unit corresponding to the above set; the time-domain precoding granularity unit corresponding to the above set.
[0379] In the above implementation, the precoding granularity unit, or bundling region, may also be called a precoding resource block group, or other equivalent name. In short, within a bundling region, the transmit beam remains unchanged, and / or the receive beam remains unchanged. The beam can be an RF beam (where different beams are represented by different RF precoding), a digital beam (where different beams are represented by different digital precoding), or a hybrid beam (where different beams are represented by different RF precoding and / or different digital precoding). Alternatively, the above precoding granularity unit is the smallest unit in which the transmit beam and / or receive beam change.
[0380] In the above embodiments, the higher-layer control information includes RRC control information, MAC CE control information, or other future control information. In short, this control information cannot be semi-statically configured, and its information changes within a time unit greater than one first time unit. The first time unit is either the minimum time unit for resource scheduling or the minimum time unit for the terminal to detect downlink control information. For example, the first time unit could be a slot or mini-slot in NR, or a subframe in LTE.
