[0148] In some embodiments, the channel configuration of the uplink channel set may include at least one of the following: channel bandwidth, number of channels, and RU duration.

[0149] In some embodiments, the channel bandwidth may be the bandwidth of each uplink channel in the uplink channel set. In some embodiments, the bandwidth of each uplink channel in the uplink channel set may be the same.

[0150] In some embodiments, the number of channels may be the number of uplink channels in an uplink channel set.

[0154] In some embodiments, the channel bandwidth and the number of channels may have a corresponding relationship. In some embodiments, the available bandwidth may be equal to the product of the channel bandwidth and the number of channels.

[0155] In some embodiments, the uplink channel set may have one or more channel configurations. Uplink channel sets with different channel configurations may differ in at least one of channel bandwidth, number of channels, and RU duration.

[0291] In the following, the technical solutions of the embodiments of the present disclosure are exemplarily described through specific implementation methods.

[0292] In some embodiments, in the A-IoT scenario, especially for the topology where the base station serves as a reader (i.e., the second device), since the base station has a larger coverage than the RFID reader, a larger number of A-IoT devices (tags) (i.e., the first device) may need to be inventoried, and for the A-IoT scenario, the A-IoT devices (tags) may be allocated more resources (such as multiple channels, multiple time slots, and multiple beams), so it is possible to consider enhancing the RFID inventory process to increase inventory efficiency.

[0293] In some embodiments, if multiple channels can be used in the frequency domain, more A-IoT devices can be supported to access different channels simultaneously in the same time slot; the current QueryAdjust signaling can only allow the device to adjust the specific time slot of its access channel in the time domain, and does not take into account the adjustment of frequency domain resources. Therefore, the adjustment mechanism of resources in the frequency domain (dynamic) can be additionally considered to enable A-IoT devices to access the channel more efficiently and complete uplink data transmission.

[0294] In some embodiments, the A-IoT device determines the dynamic adjustment of the channel size based on the QueryAdjust information sent by the base station or the UE (BS / reader) used as a reader.

[0295] In some embodiments, an initial value for the channel size can be configured. The initial value for the channel size can be indicated in the Q (Query) value, such as the frequency used for the current UL transmission, the channel bandwidth, and the number of channels. The channel bandwidth and the number of channels may have a corresponding relationship. For example, if the frequency band allocated to the UL is 2 PRBs, the corresponding bandwidth is 360 kHz when the SCS is 15 kHz, of which a total of 60 kHz can be used as a guard interval. In this case, the useful bandwidth is 300 kHz, and 20 uplink channels can be supported for simultaneous transmission. The channels are numbered 0 to 19.

[0296] In some embodiments, channel size adjustment can be implemented. In one example, a corresponding channel change indication field (i.e., second indication information) can be added to the QueryAdjust command. The specific implementation of the channel change indication field can be seen in Table 1 and Table 2.

[0297] Table 1: Channel size adjustment diagram

[0298] Table 2: Channel size adjustment diagram

[0299] In some embodiments, the corresponding configuration may be {BW size, N}, where BW size is the channel bandwidth and N is the corresponding number of channels. For example, for a total useful uplink bandwidth of 300 kHz, candidate configurations may be shown in Table 3.

[0300] Table 3: Channel bandwidth size configuration candidate value list

[0301] In some embodiments, QueryAdjust directly indicates the sequence number value of the above configuration (ie, the first indication information) instead of indicating the change value.

[0302] In some embodiments, different uplink channel bandwidths correspond to RUs with different time lengths, as shown in the fourth column of Table 3 above.

[0303] It should be noted that all the above numerical values ​​are example reference values, and the embodiments of the present disclosure include but are not limited to the configurations of the above specific values.

[0304] In some embodiments, the channel adjustment indication may also be an implicit indication, and its changed value or specifically configured value corresponds to the changed Q value in the QueryAdjust signaling. For example, if the Q value is half of that in the Query signaling, the channel bandwidth may become half of the original value, thereby increasing the number of channel bandwidths. This is only an example and is not intended to be limiting.

[0305] In some embodiments, after receiving the message information, the A-IoT device modifies, sets, or maintains the corresponding bandwidth size within the current time slot, and selects a channel from the channel set of the corresponding bandwidth size (the total number of channels has changed at this time, and the selection method can be random selection) for UL transmission.

[0306] In some embodiments, the message is used to send both the uplink random number sequence and the UL data.

[0307] In some embodiments, the A-IoT device uses a channel randomly selected (or configured, or predefined, or associated with a task / session of an inventory) from a channel set corresponding to the bandwidth size to send an uplink random number sequence (i.e., a random number) (such as RN16), and the uplink random number sequence is sent using a fixed number of RUs (such as 1 RU); for subsequent UL data reporting, the device uses the same channel in the channel set corresponding to the same bandwidth size to send data, and the number of RUs used can be indicated by the Query sent at the beginning of the round of inventory or the QueryAdjust signaling of the current time slot; correspondingly, the RU time length corresponding to the bandwidth is shown in Table 3.

[0308] In some embodiments, only for subsequent UL data reporting, the device uses a channel randomly selected (or configured, or predefined, or associated with a counted task / session) from the channel set corresponding to the bandwidth size to send data, and the number of RUs used can be indicated by the Query sent at the beginning of the round of inventory or the QueryAdjust signaling of the current time slot; for the uplink random number sequence (such as RN16), the device uses a bandwidth of a predefined size (for example, 15kHz) to send, sends the uplink random number sequence (such as RN16), and uses a fixed number of RUs (such as 1 RU) to send the uplink random number sequence; correspondingly, the RU time lengths corresponding to the two bandwidth sizes are shown in Table 3.

[0309] For the channel correspondence, if the message acts on both the uplink random number sequence and UL data, the random number (RN16) sent and the channel sequence number of the UL data sent can be one-to-one corresponding; if the message acts only on the UL data, the following operations can be performed: for RN16 transmission, it defaults to the minimum value of all candidate bandwidth sizes, such as 15kHz, then set k = (UL data bandwidth size / RN16 transmission bandwidth size), then if the channel number randomly selected for the RN16 channel is j, then use channel j to send RN16, and use channel Send UL data.

[0310] Through the above process, the reader / writer (base station or intermediate UE) can dynamically change the bandwidth occupied by UL transmission according to the situation. For example, when there are fewer collisions, it can adjust to a larger bandwidth for transmission. In this way, since the RU with a larger bandwidth has a shorter time length, the transmission time can be reduced; vice versa.

[0311] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
