In order to meet these services and demands, network providers are required to provide networks with greater connections, wider bandwidth, lower latency, and more reliability than existing networks. Therefore, a new network system architecture, namely the 5G system, has been proposed. NR (New Radio) is the air interface technology of the 5G system.
[0003] The REG-CCE (resource element group-control channel element) mapping in NR can use a non-interleaved mapping method or an interleaved mapping method. When the REG-CCE mapping uses an interleaved mapping method, if the UE (User Equipment) can assume that multiple bound REGs (Resource Element Groups) use the same demodulation method, the efficiency of channel estimation can be improved. Therefore, how to transmit information about the REG bundling size becomes a problem that needs to be solved for NR implementation.

[0086] See also Figure 1 The resource element group binding information transmission method disclosed in the present invention comprises the following steps:
[0087] Step 101, determining a bundling size of a resource element group (REG), which is used to implement mapping of interleaved REGs to CCEs (Control Channel Element) in a New Radio-Physical Downlink Control Channel (NR-PDCCH);
[0088] Step 102: Send the bundling size information of the REG to a specific UE (User Equipment) through an RRC (Radio Resource Control) message to allow the UE to demodulate the NR-PDCCH using the bundling size information of the REG.
[0089] The following specifically introduces the implementation of the REG binding information transmission method disclosed in the present invention.
[0090] The REG-CCE mapping in NR (New Radio) can use non-interleaved REG-CCE mapping or interleaved REG-CCE mapping. REG bundling technology can be used in interleaved REG-CCE mapping, and the UE can assume that multiple bound REGs use the same demodulation method, thereby improving the efficiency of channel estimation. For CORESET (Control Resource Set) with 1, 2 or 3 symbols, the supported REG bundling size (REG bundlesize) is [2or 3or 6], that is, in interleaved REG-CCE mapping, 2, 3 or 6 REGs are bundled together for processing. Therefore, the network side first needs to determine the REG bundling size, and then notify the UE of the REG bundling size.
[0091] See also Figure 2 . Figure 2 An example of mapping REGs to physical resources using interleaving technology is given. The network side first logically sorts multiple REGs to be mapped, with every 6 REGs corresponding to 1 CCE, and binds two adjacent REGs into a binding group in order (i.e., the size of the binding group is 2), and numbers these binding groups in order. Then, the two binding groups are bound into a binding set at a certain numbering interval (i.e., the size of the binding set is 2), and these binding sets are numbered in order. Finally, the interleaving technology is used to shuffle the sequentially arranged binding sets, and the shuffled binding sets are mapped to the physical resources in sequence. The REG binding size described in the present disclosure can be the binding size of the REG binding group, the binding size of the REG binding set, or the binding size including the binding size of the REG binding group and the binding size of the REG binding set.
[0092] See also Figure 3-Figure 7 , Figure 3-Figure 7Examples of multiple RRC procedures are given, and the network side (C-RAN) sends the REG bundling size to a specific UE through RRC messages in these RRC procedures. The RRC message can be any message sent by the network side to the UE side in the RRC procedure, such as RRC Connection Setup message (RRCConnectionSetup), RRC Connection Resume message (RRCConnectionResume), RRC Connection Reconfiguration message (RRCConnectionReconfiguration) or RRC Connection Re-establishment message (RRC Connection Re-establishment).
[0093] RRC is used to process the third layer information of the control plane between the UE side and the network side in the mobile communication system. RRC allocates radio resources and sends related signaling. RRC signaling messages carry all the parameters required to establish, modify and release the second layer (MAC layer) and the first layer (physical layer) entities, and also carry some signaling of the non-access layer (NAS layer).
[0094] RRC signaling consists of IE (Information Element) and fields. The IE and fields are defined as follows.
[0095] IE: A structural element containing single or multiple fields is called IE.
[0096] Fields: The individual contents of IE are called fields.
[0097] An RRC message includes multiple IEs. An IE consists of fields, each field includes separate content or another IE, and another IE may include fields or another IE.
[0098] The use of fields in IE can be optional. If a field in IE is optional, the UE behavior is usually specified for the case where the field does not exist. The purpose of using optional fields is to minimize the length of signaling messages. For example, when the network side only needs to change a small part of the UE configuration through RRC messages and most of the UE configuration remains unchanged, if the above optional field does not exist in the received RRC message of the UE, the UE continues to maintain the functions related to the content of the above optional field.
[0099] An example of an optional field, i.e., an IE configured in a CQI message, is given below:
[0100]
[0101]
[0102] In this IE, cqi_ReportModeAperiodic and cqi-ReportPeriodic are both optional fields, which are indicated by OPTIONAL in syntax. After OPTIONAL, Need OR means that if the field does not exist in the IE, the UE stops using the function configuration value related to the field. If the field exists, the UE is instructed to use the configuration value in the field. In contrast, Need ON means that if the field is missing in the IE, the UE continues to use the existing function configuration value related to the field. If the field exists in the IE, the UE is instructed to use the configuration value in the field. The field with Need ON here is called the optional continuation field.
[0103] In this embodiment, the network side can pass the information of REG bundling size to the UE by adding fields or optional fields to the IE in the RRC message. For example, the REG bundling size information can be passed through IEs such as RadioResourceConfigDedicated (dedicated radio resource configuration), PhysicalConfigDedicated (dedicated physical channel configuration), and NRPDCCH-Config (new air interface physical downlink channel configuration). Among them, RadioResourceConfigDedicated is used to establish, modify or release RBs (resource blocks), modify MAC (media access control) layer settings, modify SPS (semi-static resources) settings, and modify dedicated physical channel settings; PhysicalConfigDedicated is used to specify UE-specific physical channel settings; NRPDCCH-Config is used to specify the subframes and resource blocks monitored by NR-PDCCH (new air interface physical downlink control channel). An example is given below. The added field sizeREG-bundling-r15 in the example is used to indicate the REG bundling size, and can also be set to the Need ON optional continuation field in the corresponding IE field.
[0104]
[0105]
[0106]
[0107]
[0108]
[0109] In the above embodiment, the network side sets the information element (e.g., RadioResourceConfigDedicated) of the UE-dedicated NR-PDCCH in the RRC message format, and includes the REG bundling size information used by the UE in the field (Field) of the information element. Specifically, for example, the field of the information element RadioResourceConfigDedicated includes the information element physicalConfigDedicated, the field of the information element physicalConfigDedicated includes the information element nrpdcch-Config, and the field of the information element nrpdcch-Config (the field name is, for example, controlResourceSet-r15 or resourceBlockAssignment-r15) includes the field sizeREG-bundling-r15, ENUMERATED{n2,n3,n6}, where n2, n3, n6 represent the bundling sizes of 2, 3, and 6, respectively. Among them, Example (3) and Example (4) are two forms of the NRPDCCH-Config information element, and the REG bundling size in Example (3) is configured as part of the Coreset configuration.
[0110] The access network side (e.g. C-RAN) sends an RRC message (e.g. the above-mentioned RRCConnectionSetup, RRCConnectionResume, RRCConnectionReconfiguration, RRCConnectionReestablishment messages) to the UE to configure the UE's physical resources, and the message carries the above-mentioned IE. The UE receives the RRC message, configures the REG bundling size according to the corresponding configuration parameters, and demodulates the corresponding NR-PDCCH using the REG bundling size information.
[0111] It should be noted that the above RRC message may be an RRC message for configuring CORESET, that is, the network side configures the REG bundling size at the same time when configuring CORESET. The RRC message used to configure CORESET here may be an RRC message for configuring UE-specific or an RRC message for configuring non-UE-specific. The RRC message used to configure CORESET may also be an RRC message for configuring multiple groups of CORESETs for the same UE. These configuration methods increase the flexibility of configuration.
[0112] See also Figure 8 The resource element group binding information processing method disclosed herein includes the following steps:
[0113] Step 201, obtaining bundling size information of a resource element group REG by receiving a radio resource control RRC message, where the bundling size is used to implement mapping of interleaved resource element groups REG to control channel elements CCE in a new radio interface physical downlink control channel NR-PDCCH;
[0114] Step 202: Demodulate the NR-PDCCH using the bundling size information of the REG.
[0115] The previous article introduced the process of the base station sending the REG binding size to the UE through the RRC message. The process of the UE receiving the RRC message to obtain the REG binding size information is similar to the above process and will not be repeated here. It should be noted that the REG binding size transmitted by the base station to the UE can be the binding size of the REG bound in the frequency domain. In this case, the UE can assume that the precoding interval in the frequency domain is equal to the binding size of the REG, and then use the frequency domain precoding interval to demodulate the corresponding NR-PDCCH, making the UE demodulation more flexible and accurate.
[0116] See also Fig. 9 , the base station device disclosed in the present invention for transmitting REG binding information includes:
[0117] A bundling size determination module is used to determine a bundling size of a resource element group REG, where the bundling size is used to implement mapping of interleaved resource element groups REG to control channel elements CCE in a new radio interface physical downlink control channel NR-PDCCH;
[0118] The bundling size sending module is used to send the bundling size information of the REG to a specific user equipment UE through a radio resource control RRC message, so as to allow the UE to demodulate the NR-PDCCH using the bundling size information of the REG.
[0119] The working processes of the binding size determination module and the binding size sending module correspond to steps 101 and 102 of the REG binding information transmission method disclosed in the present invention, and will not be repeated here.
[0120] See also Fig.10 , the user equipment for REG bundling information processing disclosed herein includes: an information acquisition module, used to acquire the bundling size information of the resource element group REG by receiving a radio resource control RRC message, the bundling size being used to implement the mapping of the interleaved resource element group REG to the control channel element CCE in the new radio interface physical downlink control channel NR-PDCCH;
[0121] A demodulation channel module is used to demodulate the NR-PDCCH using the bundling size information of the REG.
[0122] The working processes of the information acquisition module and the demodulation channel module correspond to steps 201 and 202 of the REG binding information processing method disclosed in the present invention, and will not be repeated here.

[0125] Second, an optional field or an optional continuation field for expressing the REG binding size is added to the IE structure to realize information transmission, reduce the length of the signaling message, and improve transmission efficiency.
