Description
Technical Field
The invention relates to the technical field of wireless ad hoc networks, in particular to a method, equipment and medium for receiving and transmitting a control channel of a wireless ad hoc network node.
Background
Wireless communication systems typically schedule transmission and reception resources in units of time slots. For example, in LTE, time resource scheduling is performed with 1 millisecond (ms) as 1 subframe; in 5G NR, 1ms may be further divided into 1,2,4,8 slots (slots) according to a scalable subcarrier interval, and resource scheduling is performed in units of slots. On the other hand, OFDM technology (Orthogonal Frequency Division Multiplexing, i.e., orthogonal frequency division multiplexing technology) has been widely used in various wireless communication systems. Each slot may be generally divided into a plurality of OFDM symbols, each carrying a control channel and a data channel.
Typically, as in LTE, a typical downlink subframe is divided into 14 OFDM symbols 1ms, the first 1-3 bearer control channels PDCCH (Physical Downlink Control Channel) refer to physical downlink control channels), and the remaining symbols carry the shared data channel PDSCH (physical downlink shared channel, which is one of the LTE physical downlink channels and also the downlink channel for LTE to carry primary user data). The UE needs to first receive DCI (DCI, downlink Control Information, downlink control information) sent to itself in the PDCCH, to obtain whether there is a downlink or uplink shared data channel allocated to itself, and if there is an indication of frequency domain resources, modulation scheme, coding rate, etc. occupied by the data channel, then further use the configuration to receive PDSCH allocated to itself. Since the base station needs to schedule all UEs in the cell, and the time-frequency domain resource of the PDCCH includes DCI information of all UEs that need to be scheduled in the current subframe, for a specific UE, blind detection is performed on all possible positions included in the PDCCH symbol according to a specific rule, and then whether the current subframe has a PDSCH channel allocated to itself can be known. In LTE PDCCH blind detection, UE uses different configuration length and different DCI size in different search spaces, and needs to perform blind detection for 44 times at most, where each blind detection includes signal processing such as data extraction, descrambling, deinterleaving, rate-de-matching, channel decoding, and CRC check, and occupies considerable power consumption of the user terminal.
In 5G NR, the basic principle is the same as LTE, and users need to perform a maximum of several tens of blind tests (different subcarrier spacing has different maximum blind test times).
Since the PDCCH carries data channel allocation information, it is typically placed in the foremost symbol of the resource scheduling slot. Wherein the time slots represent resource scheduling time units.
With the increase of multimedia services such as images, videos and the like in wireless ad hoc networks, more and more wireless ad hoc network products refer to LTE/NR in a physical layer, and transmit and receive resource indication is performed in a resource scheduling unit time slot by using a control symbol and a data symbol by adopting a broadband OFDM technology and a similar wireless frame structure.
In the wireless ad hoc network, no base station role exists, and semi-static or dynamic time slot resources are allocated to all user nodes in the network for transmission according to a private protocol. The communication means may be unicast to a particular user or broadcast to all users within the network. In industry applications, a user allocated to a transmitting timeslot (e.g., in a polling manner) may not have data traffic to transmit in the current timeslot, and other users in the ad hoc network still need to monitor and receive control symbols first and perform blind detection. Although the reception of control symbols is generally simpler than the reception of data symbols, it is still necessary to perform channel estimation, demodulation, and then data extraction and concatenation, descrambling, rate matching, and channel decoding on the control channel symbols for a plurality of possible positions. Performing such acceptance processing every time slot may consume greater power consumption by the network node, especially for wireless ad hoc network products employing wideband OFDM technology.
In addition, in the OFDM system, pilot data with a certain overhead is inserted through the time-frequency domain position, and the receiver can perform wireless channel estimation by using the known pilot data to ensure the receiving performance. In some wireless ad hoc networking technologies, when users do not need to transmit, neither the user pilot nor the data is transmitted, and other receiving users can determine whether the transmitting user has data to transmit by detecting the energy of the pilot location signal, however this technology has the following drawbacks:
(1) different from a system of serving users by base stations such as LTE/NR and the like, the wireless self-organizing network can continuously or periodically send pilot frequency, and a cell mobile user can continuously track time frequency offset of a wireless channel according to the pilot frequency. In the wireless ad hoc network, without a fixed base station, users of each node send in turn, the sending time interval may be relatively long, in this case, other user nodes need to keep time frequency offset tracking for each sending node by using pilot frequency, and if the pilot frequency is not sent, it may cause that the wireless links between other users and the node are not tracked or even broken.
(2) In a wireless propagation environment, a pilot signal may be affected by multipath fading and the like, so that energy is weak, and judgment is inaccurate.
Therefore, how to know in advance whether the effective data needs to be received in the current time slot, and further determine whether to close the circuit for receiving the data in advance, so as to achieve the purpose of saving power consumption is a technical problem to be solved in the prior art.

More preferably, the frequency domain mapping is according to agreed rules: according to any rule of node ID calculation which is uniformly distributed in the frequency domain, the transmitting and receiving parties calculate according to the node ID of the transmitted data. The frequency domain mapping may be according to a rule, for example, a rule that the node IDs are calculated according to a certain rule that the node IDs are uniformly distributed in the frequency domain, and the transceiver can calculate itself according to the node IDs of the transmission data.
Looking at typical parameters, the wideband 20M and 15KHz sub-carriers, system 1200 sub-carriers, if the RTI repetition coding parameter k=24, occupy K/2=12 sub-carriers, corresponding to 1% of the number of available sub-carriers, are quite small for the overhead.
As shown in fig. 1, in this embodiment, the information in the physical channel indicated by the existence of the physical resource is received by the receiver, and the process of receiving the information and processing the information by the receiver through the OFDM receiver is specifically as follows:

Further extensions of this embodiment may also use two bits, i.e. an additional one bit, to indicate if pilot is sent if no data is sent in the current slot. In this way the receiver can further make finer control selections, for example, if it is known that the current slot has no data to send, but pilot to send, it can further decide whether or not it is necessary to keep receiving pilot to maintain the time-frequency offset tracking adjustment. Table 1 can then be extended to more repetition coding schemes.
