Abstract
Description
Technical Field
[0001] This application relates to the field of communications, and more specifically, to a method and apparatus for transmitting uplink control information. Background Technology
[0002] In a communication system, the UE needs to send necessary uplink L1 (PHY Layer) and L2 (MAC Layer) control information to support uplink and downlink data transmission. Taking the LTE / LTE-A system as an example, the uplink L1 / L2 control information (UCI) includes the following:
[0003] SR (Scheduling Request): Used to request uplink UL-SCH resources from the eNodeB.
[0004] HARQ acknowledgment or negative acknowledgment (ACK / NACK): HARQ acknowledgment is performed on downlink data transmitted on the Physical Downlink Shared Channel (PDSCH).
[0005] CSI: Channel State Information, including Channel Quality Indication (CQI), Precoding Matrix Indicator / Index (PMI), Rank Indicator (RI), and CSI-RS Resource Indicator / Index (CRI). It is used to inform the eNodeB about downlink channel quality, thus assisting the eNodeB in downlink scheduling.
[0006] In LTE, control information is transmitted in two ways: If the UE is not allocated uplink resources for uplink data transmission in the current subframe, it uses the Physical Uplink Control Channel (PUCCH) to transmit uplink L1 / L2 control information. If the UE is allocated uplink resources for uplink data transmission in the current subframe, it uses a portion of the resources allocated by the Physical Uplink Share Channel (PUSCH) to transmit uplink L1 / L2 control information. If the UE has already been allocated uplink data resources, there is no need to transmit SR (Static Signal). If carrier aggregation exists, control information from multiple carriers can be aggregated and transmitted together.
[0007] For control transmission on PUCCH, there are several formats (uplink control channel formats), as shown in Table 1. Each format corresponds to different control information.
[0008] Table 1
[0009]
[0010]
[0011] As shown in the table above, different control information types can be transmitted individually or combined with other control information types, forming different formats. Transmission of the same format under the same antenna configuration follows a relatively fixed design and cannot be flexibly changed. This is because the primary consideration in LTE is the robustness of the transmitted content. Control information requires a very low bit error rate, and errors in control information can lead to more serious consequences than errors in data information; therefore, it is designed in the most robust manner. The uplink control channel typically distinguishes different users through code division. Code division can achieve orthogonality by using different orthogonal sequences or cyclic shifts of the same sequence.
[0012] LTE / LTE-A primarily targets lower frequency communication frequencies, where path loss is not particularly significant. However, with the gradual development and utilization of higher frequencies, the communication frequency of the system is increasing, expanding to 4GHz, 30GHz, and 70GHz, at which point path loss will increase significantly. To combat high-frequency path loss, beamforming gain based on beam transmission is adopted to ensure control channel coverage, which has become a trend. However, beam transmission requires real-time and accurate channel state information (CSI). In actual systems, transmission path congestion, terminal movement, and terminal rotation can affect beam accuracy, thus challenging the robustness of the control channel.
[0013] The current problem with control information feedback is that if the most robust method is used to send uplink control information, it is necessary to send it in all beam directions, and each direction requires resources. The number of beams is generally twice the number of antennas, which requires a lot of resources. On the other hand, if the method with the highest transmission efficiency is used to send uplink control information, it will face robustness issues. Beams always have problems with measurement accuracy and real-time performance. Therefore, there is a lack of a control information transmission method that can guarantee both robustness and high transmission efficiency.
[0014] Therefore, no solution has yet been proposed for the problem that information transmission cannot guarantee both robustness and high transmission efficiency in related technologies. Summary of the Invention

[0221] Optionally, specific examples in this embodiment can refer to the examples described in the above embodiments and optional implementations, and will not be repeated here.
[0222] Example 4
[0223] Step 101: Determine the first type of information; the first type of information includes the previously mentioned response message; scheduling request message; CSI information; transmission mode switching request information; reception mode switching feedback information; information reporting mode indication information;
[0224] At any given moment, the terminal needs to determine the content of the information to be reported based on the current feedback mode, the base station's triggering signaling, and some agreements with the base station. At the same time, there may be only one type of first-class information that needs to be reported, or there may be multiple types of first-class information that need to be reported. When multiple types of information need to be reported, they can be merged and reported, or they can be reported separately.
[0225] Step 102: Determine the transmission configuration set corresponding to the first type of information;
[0226] The first type of information can correspond to different sets of transmission configurations, and the transmission configurations in these sets are used for the transmission of the first type of information; the specific transmission configurations include some parameter types, which will be described in the following embodiments.
[0227] There are several ways to determine the transmission configuration set corresponding to the first type of information: one way is to pre-agree on what the transmission configuration set corresponding to the first type of information is; another way is to require the base station to configure the transmission configuration set through configuration signaling; if the base station sends a configuration set indication signaling, the terminal needs to determine what this set is according to the indication of the configuration signaling, and different terminals can configure different transmission configuration sets; different uplink or downlink transmission modes can correspond to different agreements or configurations of transmission configuration sets, so regardless of whether it is pre-agreement or requires base station signaling indication, the terminal needs to determine the transmission configuration set by combining the uplink or downlink transmission mode; different information types contained in the first type of information may correspond to different agreements or configurations of transmission configuration sets, so regardless of whether it is pre-agreement or requires base station signaling indication, the terminal needs to determine the transmission configuration set by combining the information types contained in the first type of information.
[0228] It should be noted that when the first information type is a response message, different response objects should also be considered as different types. For example, data response messages and control response messages may correspond to different transmission configuration sets.
[0229] It should be noted that when the first information type is CSI, different CSI information subtypes should also be considered as different types. For example, CRI, RI, PMI, and CQI may correspond to different sets of transmission configurations.
[0230] For response messages, if the response is for the first transmission of data, the transmission configuration set may differ from that when the response data is for retransmission. Therefore, regardless of whether it is pre-agreed or requires base station signaling indication, the terminal needs to determine the transmission configuration set by considering whether the response data is the first transmission or a retransmission, and if it is a retransmission, how many times it has been retransmitted.
[0231] The optimal set of different transmission configurations is different, so different sets can be pre-selected according to the characteristics of the first type of information. Generally speaking, very important information and information with a very low transmission frequency can consider a highly robust transmission configuration; information of moderate importance can consider a moderately robust transmission configuration and a transmission configuration with higher transmission efficiency. It should be noted that the more robust it is, the more resources are required, including resources in the time domain, frequency domain, spatial domain, code domain, and power, while high transmission efficiency means successfully transmitting information with fewer resources.
[0232] Step 103: Select a transmission configuration from the set of transmission configurations;
[0233] If the base station sends a configuration selection indication signaling, the terminal needs to select from the set according to the indication in the signaling. Preferably, this signaling is physical layer control signaling, which allows for rapid configuration switching and flexible selection from the configuration set. Another scenario is the absence of indication signaling. In this case, the terminal can flexibly select on its own, with different terminals choosing different transmission configurations from the set. Alternatively, the terminal can select based on the transmission mode, the type of information contained in the first type of information, the object of the acknowledgment, the number of retransmissions of the acknowledgment information, etc. Different uplink or downlink transmission modes can select different transmission configurations from the set, as can different types of information contained in the first type of information.
[0234] It should be noted that when the first information type is a response message, different response objects should also be considered as different types. For example, data response messages and control response messages may correspond to different transmission configuration selections.
[0235] It should be noted that when the first information type is CSI, different CSI information subtypes should also be considered as different types. For example, CRI, RI, PMI, and CQI may correspond to different transmission configuration options.
[0236] For response messages, the transmission configuration selection may differ if the response is for first-transmission data and if the response data is for retransmission data. Therefore, regardless of whether it is pre-agreed or requires base station signaling indication, the terminal needs to determine the transmission configuration selection based on whether the response data is the first-transmission or a retransmission, and if it is a retransmission, how many times it has been retransmitted. If the corresponding transmission configuration set contains only one configuration, then that configuration is used directly.
[0237] Step 104: Transmit the first type of information according to the selected transmission configuration;
[0238] Example 5
[0239] The terminal can determine the transmission configuration set based on the information type contained in the first type of information. The specific transmission configuration type will be described in the following embodiments. The specific method for determining this set can be referred to the method mentioned in Embodiment 1.
[0240] One scenario is that a type of first-class information corresponds to a set of transmission configurations, as shown in Table 2.
[0241] Table 2
[0242] "Scheduling Request Message" Transmission Configuration 11, Transmission Configuration 12 "Response message" for control information Transmission Configuration 21, Transmission Configuration 22 "Response message" for data information Transmission configuration 31, transmission configuration 32 "Request to switch sending method" Transmission configuration 41, transmission configuration 42 "Request to switch receiving method" Transmission configuration 51, transmission configuration 52 "Information Reporting Mode Instruction Information" Transmission configuration 61, transmission configuration 62
[0243] This only lists the cases that correspond to multiple configurations. It is also possible that one type of information corresponds to only one configuration; or that some types of information correspond to only one configuration and some types of information correspond to multiple configurations.
[0244] Another approach is to group the first type of information, with each group corresponding to a transmission configuration set; there are several ways to group the transmission configuration sets.
[0245] The first preferred grouping method is as follows: the first group includes one or more of the following: "Scheduling Request Message", "Response Message", "BI", "CRI", "RI", "Send Mode Switching Request Message", "Receive Mode Switching Request Message", and "Information Reporting Mode Indication Message"; the second group includes one or more of the following: "CQI" and "PMI", as shown in Table 3.
[0246] Table 3
[0247]
[0248] If there are multiple PMI feedbacks, including a long-cycle, broadband first PMI and a short-cycle subband feedback second PMI, the grouping method is shown in Table 4.
[0249] Table 4
[0250]
[0251] The second preferred grouping method is as follows: the first group includes one or more of the following: "scheduling request message", "response message", "send mode switching request information", "receive mode switching request information" and "information reporting mode indication information", and the other group includes one or more of the following CSI information, as shown in Table 5.
[0252] Table 5
[0253]
[0254] The third preferred grouping method is as follows: the first group includes one or more of the following: "scheduling request message", "sending mode switching request information", "receiving mode switching request information" and "information reporting mode indication information"; the other group includes one or more of the following: "response message" and "CSI information", as shown in Table 6.
[0255] Table 6
[0256]
[0257] Besides the two-group method mentioned above, it can be easily extended to dividing into more groups. Information with similar importance and transmission frequency can be grouped together. Each group can correspond to a transmission configuration set, and a transmission configuration contains one or more transmission configurations; different groups may have different transmission configuration sets due to their different characteristics.
[0258] Example 6
[0259] This embodiment mainly illustrates some configuration types included in the transport configuration set, which mainly include:
[0260] Configuration of one or more Numerology:
[0261] In typical OFDM-based wireless communication systems, the basic transmission parameters mainly include the following categories:
[0262] Time-domain symbol length: refers to the length of an OFDM symbol. A modulation symbol is carried on M OFDM subcarriers. These subcarriers, when transformed to the time domain, constitute a time-domain sample. Adding a guard interval results in a time-domain OFDM symbol. Generally, the length of an OFDM symbol is related to the number and spacing of the subcarriers in the frequency domain. For the same bandwidth, more subcarriers and smaller spacing result in a longer OFDM symbol. Alternatively, it can be described as follows: with the same subcarrier spacing, more subcarriers result in a longer OFDM symbol; and vice versa.
[0263] Subcarrier number: refers to the number of subcarriers that carry modulation symbols in the frequency domain corresponding to the same OFDM symbol;
[0264] Subcarrier spacing: The interval between the center frequencies of subcarriers. Generally speaking, in order to maintain orthogonality, the smaller the subcarrier spacing, the higher the waveform requirements and the longer the window in the time domain, and therefore the longer the time domain symbol, and vice versa.
[0265] Frequency domain guard band: When transmitting information, some bandwidth is usually reserved on both sides as a guard band. For example, if the current LTE system uses only 100 RBs (resource blocks) under a 20MHz bandwidth, it only occupies 1200 subcarriers with a total bandwidth of 18MHz. This means that a 2MHz guard band is reserved. It is usually placed on both sides of the bandwidth, mainly to prevent the out-of-band leakage of information transmitted by other wireless communication systems from affecting the performance.
[0266] Cyclic prefix (CP) typically refers to adding a prefix to the time-domain samples formed after a frequency-domain signal is converted to the time domain. This prefix is usually a copy of the later part of a sequence of time-domain samples. For example, adding a cyclic prefix of length 4 to the sequence 0,1,2,3,4,5,6,7,8,9 results in 6,7,8,9,0,1,2,3,4,5,6,7,8,9.
[0267] Time-domain guard interval (GP): When RF precoding is present, switching from one precoding to another requires a certain processing time, so a similar guard interval is also needed. Similar guard interval concepts exist in other places as well. In this application, all kinds of guard intervals are considered to be a kind of basic transmission parameter.
[0268] FFT points: Generally related to the number of baseband subcarriers and bandwidth, but not exactly equal to the number of effective subcarriers. For example, for a 20MHz / 10MHz LTE system, we use 2048 points and 1024 points respectively, but the number of effective subcarriers is only 1200 and 600.
[0269] In this application, one or more sets of numberology parameters may be used, and each set of basic parameter configurations may include one or more of the types mentioned above;
[0270] Configuration of one or more transmission zones;
[0271] The configuration of transmission areas here includes: time-domain transmission area configuration, such as which subframe group, which time slot group, and which OFDM symbol group it is on. It also includes frequency-domain transmission area configuration, such as which subcarrier groups it is on; or a combination of the two, such as which RB groups in which subframes it is on; if there are multiple transmission areas, it is a set of multiple time-frequency resource areas defined; these areas can be pre-configured.
[0272] Configuration of one or more sets of transmit code sequences;
[0273] Code sequences are also a resource, so which code sequences are available is also a configuration of candidate transmission resources, which can be considered a transmission configuration.
[0274] Configuration of one or more transmission powers;
[0275] Configuration of one or more sending counts;
[0276] Some information can be repeatedly sent continuously for greater robustness; the number of times it is sent is a transmission configuration.
[0277] One or more send resource number configurations;
[0278] Different numbers of resources sent result in different levels of robustness. Sending a larger number of resources results in higher robustness. The number of resources sent is a type of transmission configuration.
[0279] One or more send resource granularity configurations;
[0280] One or more modulation schemes can be configured, including BPSK, QPSK, and some other modulation schemes;
[0281] One or more encoding methods can be configured, including: bitrate, encoding type, and aggregation level of control information;
[0282] Configuration of one or more transmission methods, including: configuration of the transmission beam; configuration of the transmission antenna; configuration of the transmission sector; configuration of the transmission technology / mode;
[0283] The configuration of one or more receiving methods includes: receiving beam configuration; receiving antenna configuration; receiving sector configuration.
[0284] Example 7
[0285] Step 201: Determine the first type of information
[0286] The first category of information includes the previously mentioned response messages; scheduling request messages; CSI information; transmission mode switching request information; reception mode switching feedback information; and information reporting mode indication information.
[0287] At any given moment, the terminal needs to determine the content of the information to be reported based on the current feedback mode, the base station's triggering signaling, and some agreements with the base station. At the same time, there may be only one type of first-class information that needs to be reported, or there may be multiple types of first-class information that need to be reported. When multiple types of information need to be reported, they can be merged and reported, or they can be reported separately.
[0288] Step 202: Determine the set of candidate transmission regions corresponding to the first type of information;
[0289] The candidate transmission area set contains at least M transmission areas; M>1, and is an integer.
[0290] This set of transmission areas can be pre-agreed or configured; since the set of transmission areas is also a form of transmission configuration set, please refer to Example 1.
[0291] Step 203: Select a transmission region from the set of transmission regions; 1 <= N <= M, where N is an integer;
[0292] Since the transmission area is also a type of transmission configuration, please refer to Example 1;
[0293] Step 204: Transmit the first type of information over the selected N regions;
[0294] Preferably, in order to provide multiple transmission powers to adapt to the transmission requirements of different first information, different terminals, and different link quality conditions, at least two regions i and j exist among the M regions. When transmission is performed on regions i and j, there is a transmission power offset P between the two regions; wherein, P can be configured by the base station.
[0295] Preferably, in order to provide multiple transmission powers to adapt to the transmission requirements of different first information, different terminals, and different link quality conditions, at least two regions i and j exist among the M regions. When transmission is performed in regions i and j, the transmission beam used by region i is a subset of that of region j, the transmission antenna used by region i is a subset of that of region j, the transmission sector used by region i is a subset of that of region j, the reception beam used by region i is a subset of that of region j, the reception antenna used by region i is a subset of that of region j, the reception sector used by region i is a subset of that of region j, the CP length of the OFDM symbol used by region i is less than the CP length of the OFDM symbol used by region j, the subcarrier spacing used by region i is less than the subcarrier spacing length of region j, the bandwidth of region i is less than the bandwidth of region j, or the number of OFDM symbols in region i is less than the number of OFDM symbols in region j.
[0296] Preferably, in order to provide multiple transmission powers to adapt to the transmission requirements of different first information, different terminals, and different link quality conditions, at least two regions i and j exist among the M regions, where the time-domain symbols corresponding to region i are a subset of the time-domain symbols corresponding to region j, and the resource blocks occupied by region i are a subset of the resource blocks occupied by region j. Alternatively, regions i and j employ different numberology parameters, wherein the different numberology parameters include: different time-domain symbol lengths; different subcarrier spacings; different subcarrier densities; different CP lengths; different frequency domain guard bands; and different guard intervals (GP).
[0297] Preferably, the M regions correspond to the M subframe groups configured by the base station or the M resource block groups configured by the base station.
[0298] Example 8
[0299] Step 301: Divide the first type of information into M groups according to the information type; each group of the first type of information corresponds to a set of transmission configurations; the set of transmission configurations contains one or more transmission configurations; M>=1, which is an integer.
[0300] Step 302: Determine the group to which the first type of information to be sent belongs; and select a transmission configuration from the set of transmission configurations corresponding to that group;
