[0031] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0032] The indication information configuration method described in the embodiment of the present disclosure is implemented by a network device, which is used to configure the indication information and send the indication information to the terminal device. The indication information is MAC CE (Media Access Control Control Element). The terminal device can obtain the indication information sent by the network device through MAC CE signaling, thereby obtaining the TCI state corresponding to the communication transmission, and perform data transmission according to the TCI state.

[0033] TCI is used to inform the terminal device to use the same receive beam as the SSB (synchronization signal block) or CSI-RS (channel state information reference signal) sent by the receiving base station when receiving PDCCH (Physical Downlink Control Channel) or PDSCH (physical downlink share channel); or to inform the terminal device to use the same transmit beam as the reference signal when sending PUCCH (physical uplink control channel) or PUSCH (physical uplink share channel), such as the SRS (sounding reference signal) or the transmit beam corresponding to the CSI-RS receive beam.

[0034] The embodiments of the present disclosure can be applied to various communication systems, such as long term evolution (LTE) systems, fifth generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems.

[0035] The network device described in the embodiments of the present disclosure may be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system.

[0036] The terminal device described in the embodiments of the present disclosure is an entity on the terminal side for receiving or transmitting signals. The terminal device may also be referred to as a terminal device (terminal), user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc.

[0037] To further expand the dimensions of traditional MIMO and thereby improve spectrum efficiency, this disclosure proposes a QCL (Quasi Co-Location) configuration method for a novel MIMO transmission scheme, defining a new TCI state activation / deactivation MAC-CE structure. Referring to Figure 1, which is a flowchart of an indication information configuration method provided by an embodiment of the present disclosure, the network device is configured to perform the following steps:

[0038] S1. Obtain system parameters of network devices;

[0039] S2. Determine, according to the system parameters, the number of TCI states to be configured corresponding to each TCI code point in the indication information;

[0040] S3. Establish an association relationship between each TCI code point and a corresponding number of TCI states that match the number to be configured.

[0041] Specifically, for the value of the number M of TCI states to be configured corresponding to each TCI code point, the present embodiment provides two methods for determining the value: one is to directly determine the value based on system parameters, and the other is to determine the value based on system parameters and bandwidth. Optionally, the system parameters include at least one of an upsampling factor, a downsampling factor, an upsampling rate, and a downsampling rate.

[0042] In a first embodiment, the number M of TCI states associated with a code point can be directly equal to the upsampling factor / downsampling factor, or directly equal to the upsampling rate / downsampling rate, for example, the upsampling factor / downsampling factor (upsampling rate / downsampling rate) can be 1, 4, 8, 16, etc., that is, M=1, 4, 8, 16, etc. Alternatively, the system parameter K can be directly equal to the upsampling factor / downsampling factor (upsampling rate / downsampling rate), for example, when the upsampling factor / downsampling factor is 4, K=4, or the system parameter K can be a function of the upsampling factor / downsampling factor, such as a linear function, and the system parameter K is directly proportional to the upsampling factor / downsampling factor, for example, when the upsampling factor / downsampling factor is 4, K is 8, 12, 16, or 20, etc.

[0043] In a second embodiment, the system parameter K is also related to the bandwidth, and the system parameter K is inversely proportional to the bandwidth. In the embodiment of the present disclosure, a method for taking the value of the system parameter K at different bandwidths and upsampling factors / downsampling factors is provided. See Table 1. The bandwidth values ​​include 2.5M, 5M, 10M, 15M, 50M, 25M, ..., 100M, and the upsampling factor / downsampling factor values ​​include 1, 4, 8, and 16. For example, when the system bandwidth is 5M and the upsampling factor / downsampling factor is 1, the value of the system parameter K is 256. At this time, based on K=256, the value of M is further obtained, such as M=256, or M=K / 2=128, or M=K / 4=64.

[0044] Table 1 Values ​​of system parameter K at different bandwidths and upsampling factors / downsampling factors

[0045] Specifically, after determining the number M of TCI states to be configured corresponding to each TCI code point, the method also includes: configuring the indication domain parameters of all TCI states in each TCI code point; wherein the indication domain parameters are used to indicate whether the indication domain of the corresponding TCI state appears, and when the indication domain parameter is a first set value, it indicates that the indication domain of the TCI state appears, and when the indication domain parameter is a second set value, it indicates that the indication domain of the TCI state does not appear.

[0046] Exemplarily, the TCI state includes two states: activation and deactivation. In the embodiment of the present disclosure, a MAC-CE may be provided with N TCI code points, each TCI code point corresponds to M TCI states, and all TCI states in the TCI code point correspond to independent transmission configuration indications. There are at most M TCI states associated with one TCI code point. When there are N TCI code points in the system, there are M*N TCI states in the system. In order to support a TCI code point indicating multiple TCI states, it is necessary to enhance the TCI state activation / deactivation MAC-CE format.

[0047] Refer to Figure 2, which is a schematic diagram of the format of the indication information provided by the embodiment of the present disclosure. R is a reserved bit, Serving Cell ID indicates the serving cell using this MAC-CE, and BWP ID indicates the index of BWP (Bandwidth Part), which is also the code point of BWP in DCI. Oct refers to the unit byte length. C 0,1 、C 0,2 ...C N,1 、C N,2 For example, the first setting value is 1, the second setting value is 0, and C i,j Used to indicate TCI state ID i,j+1 Whether the domain appears, that is, if C i,j =1, then TCI state ID i,j+1 Appears; if C i,j =0, then TCI state ID i,j+1 The domain does not appear. Where 0≤i≤N, 1≤j≤M. The specific value of N can be set by the network device and is not specifically limited here.

[0048] For example, C in FIG. 2 0,1 Indicates the first TCI state corresponding to the first code point, using TCI state ID 0,1 Indicates that C 0,2 Indicates the second TCI state corresponding to the first code point, using TCI state ID 0,2 Indicates that, and so on, until reaching M code points, C N,1 Indicates the first TCI state corresponding to the N+1th code point, using TCI state ID N,1 Indicates that C N,2 Indicates the second TCI state corresponding to the N+1th code point, using TCI state IDN,2 express.

[0049] In the indication information, a reserved bit R is set at the beginning and end of each TCI code point, which is 0 by default. The indication information can reuse the reserved bit R or introduce a new bit. The role of the reserved bit is to facilitate subsequent function expansion or enhancement. i,j Can be used to indicate TCI state ID i,j+1 Whether the domain appears continuously or not, it needs to occupy continuous positions, and only the first and last positions are left for extension. Therefore, a reserved bit R is set at the end position of the indication information.

[0050] Specifically, the configuration of the indication field parameters of all TCI states in each TCI code point includes: for each TCI code point, when there is a target indication field parameter corresponding to the TCI state that does not appear, configuring the target indication field parameter and the indication fields of the TCI states corresponding to the remaining indication field parameters whose sequence numbers follow the target indication field parameter to not appear, and deleting the fields of the remaining indication field parameters in the indication information.

[0051] For example, for the i-th TCI code point, the TCI state ID i,j The fields can only appear consecutively, i.e.: TCI state ID i,1 ,...,TCI state ID i,j If the target indication domain parameter is C i,j+1 Corresponding TCI state ID i,j+1 Is the first code point in the i-th code point to be i,j If the domain does not appear, the remaining indication domain parameter is C i,j+2 ~C i,M Corresponding TCI state ID i,j+1 ,...,TCI state ID i,M In this case, the corresponding indicator field parameter field C in front of these fields i,j+1 ,...,C i,M No need to show up.

[0052] In the embodiment of the present disclosure, by configuring the TCI state ID i,j The continuous structure of the presence or absence of a domain can save signaling resources, avoid resource waste, and further reduce overhead.

[0053] Specifically, the method further includes: configuring demodulation reference signal ports corresponding to all TCI states in each TCI code point in different code division multiplexing groups.

[0054] For example, considering the non-ideal orthogonality of different beams, if the DM-RS (Demodulation Reference Signal) ports corresponding to different TCI states are in a CDM (Code Division Multiplexing) group, it may affect the demodulation performance of DM-RSOCC (Orthogonal Cover Code), resulting in inaccurate interference measurement results. Therefore, the M DM-RS ports corresponding to the M TCI states under a TCI code point are configured in different CDM groups.

[0055] In the embodiment of the present disclosure, by configuring the demodulation reference signal ports corresponding to all TCI states in each TCI code point in different code division multiplexing groups, interference can be reduced and the demodulation performance of DM-RSOCC can be improved.

[0056] Specifically, the method further includes associating all TCI states in each TCI code point with a sampling point group within an orthogonal frequency division multiplexing symbol; wherein the orthogonal frequency division multiplexing symbol includes a plurality of sampling point groups, one TCI state is associated with one sampling point group, and each sampling point group includes at least one sampling point.

[0057] For example, the M TCI states associated with a TCI codepoint are all associated with a sampling point group within / between an OFDM symbol, with each sampling point group containing P sampling points. For example, if an OFDM symbol contains 2048 sampling points and P = 4, the sampling points within an OFDM symbol can be divided into a total of G = 2048 / 4 = 512 sampling point groups. The g-th sampling point group within an OFDM symbol is associated with the (g mod M)-th or (g mod M)+1-th TCI state for a TCI codepoint. "g mod M" indicates that the g-th sampling point group is associated with a specific TCI state among the M TCI states, or that the association between sampling points and TCI states can be set according to a defined table.

[0058] In the disclosed embodiments, antenna characteristics are modified by configuring different sampling points or sampling point groups within a single OFDM symbol, thereby achieving the goal of creating multiple virtual MIMO channels for multi-stream transmission. By establishing a correspondence between sampling point groups and antenna spatial characteristics, the new MAC-CE format can simultaneously indicate multiple (M) different antenna spatial characteristics, such as beam directions or correlation with certain reference signals (SSBs or CSI-RS), thereby supporting the goal of rapidly changing the spatial characteristics of the transmit / receive antennas within a single OFDM symbol.

[0059] In an embodiment of the present disclosure, the method further includes: sending the indication information.

[0060] Compared with the prior art, the indication information configuration method disclosed in the embodiment of the present invention determines the number of TCI states to be configured corresponding to each TCI code point in the indication information by obtaining the system parameters of the network device, and then establishes an association relationship between each TCI code point and the corresponding multiple TCI states that meet the said number to be configured, so that one TCI code point can be associated with multiple TCI states, breaking the constraint that the maximum number of transmitted data streams is limited by the actual number of physical RF channels, thereby better supporting the rapid change of the antenna spatial characteristics of the transmitting / receiving antenna within an OFDM symbol.
