Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a communications device for transmitting and receiving a reference signal.
Background
There are various reference signals in a wireless communication system, such as: channel state information reference signals (CSI-RS), Demodulation reference signals (DM-RS), Primary Synchronization Signals (PSS), Secondary Synchronization Signals (SSS), and the like in a New Radio (NR) system.
For a Reference Signal (RS) transmitted periodically, a transmission period may include a plurality of transmission opportunities. One RS resource may include one or more transmission occasions. One RS resource may be used to carry identification bits of a transmitting end, such as a base station ID, a gNB ID, an ID of a set to which the gNB belongs, an ID configured for the gNB by the network, and the like. An example of a periodic reference signal configuration is shown in fig. 1.
For example, there are M transmission occasions in one RS transmission period, and one RS resource includes 2 transmission occasions, then there may be M/2 RS resources in a time domain in one transmission period.
There may be multiple possible locations for the RS resource in the frequency domain. As shown in fig. 2, there are 2 positions in the frequency domain where the reference signal can be transmitted. In this case, the configuration of the RS resource should also include the location of the frequency domain resource. Assuming that there are N possible locations in the frequency domain, continuing with the previous example, there may be MN/2 RS resources in one cycle.
The sequences used for reference signal transmission may also be different. If different sequences are used, the reference signals transmitted on the same time-frequency resource may also be detected at the receiving end, depending on the specific design.
Thus, a reference signal is defined, the time-frequency location of the resource transmitting the reference signal needs to be defined, and the sequence used. If the transmitting end needs to transmit various information through the reference signal, the configuration of the reference signal is complicated.

In some preferred embodiments of the invention, the information bits comprise at least one of:

Preferably, the information bits include at least two information bits, and the step of obtaining the reference signal resource identifier according to the information bits includes:
and combining the at least two information bits, and calculating the combined information bits to obtain the reference signal resource identifier.
That is, the determined at least two information bits are combined and operated (for example, concatenated, jointly coded, etc.), so as to obtain the reference signal resource identifier.
Preferably, the step of combining the at least two information bits and calculating the combined information bits to obtain the reference signal resource identifier includes:
cascading the at least two information bits according to a sequence to obtain the reference signal resource identifier;
alternatively, the first and second electrodes may be,

For example, the information bits include identification bits of a sender (length N1 bits) and functional bits of a sender (length N2 bits). The reference signal resource identifier may be obtained by concatenating the N1 bits of sender identification bits and the N2 bits of sender functional bits, as shown in fig. 5, where the sender functional bits are 2, that is, N2 is 2.

Taking fig. 6 as an example, the reference signal resource identifier includes: a first bit section, a second bit section, and a third bit section. The lowest 3 bits (i.e., a) in the reference signal resource identifier2，a1，a0) Is the first bit segment used to determine the sequence used. Bit 4 (i.e., a) in the reference signal resource identifier3) Is a second bit segment for determining the frequency domain resource location of the reference signal. Other bits (i.e. a) in the reference signal resource identityN，…，a4) Is a third bit segment for determining the time domain resource location of the reference signal.
Specifically, assuming that there are K (in fig. 6, K ═ 8) candidate sequences available for transmission, the value of the lowest 3-bit of the reference signal resource identifier is mapped to one of the K sequences. For example, "000" maps to the 1 st sequence, "001" maps to the 2 nd sequence, and so on.
The frequency domain resources are selected with 1 bit, and there are 2 possible frequency domain positions in the corresponding frequency domain, for example: a "0" corresponds to the 1 st frequency domain position and a "1" corresponds to the 2 nd frequency domain position.
Assuming that there are L resource locations in the time domain in a period, use "a" toN，…，a4"map to one of the resource locations, for example: "00 … 00" maps to the 1 st time domain position, "00 … 01" maps to the 2 nd time domain position, and so on.
Of course, the reference signal resource identifier may also include any two of the first bit segment, the second bit segment and the third bit segment, and the present invention is not limited thereto.
Preferably, the mapping relationship is configured by a network side device, or agreed by a protocol.
Based on the same inventive concept, the present invention further provides a reference signal receiving method, please refer to fig. 7, fig. 7 is a flowchart of a reference signal receiving method according to a second embodiment of the present invention, as shown in fig. 4, including the following steps:

In the embodiment of the invention, the reference signal resource identifier is determined according to the detected time-frequency resource and sequence of the reference signal, and then the reference signal resource identifier is analyzed to obtain the information bit transmitted by the sending end through the reference signal, so that the configuration of the reference signal is simpler, and the efficiency of information transmission can be improved.
Preferably, the step of detecting the sequence of the reference signal on the time domain resource and the frequency domain resource of the reference signal includes:
detecting all possible sequences of the reference signal on all possible candidate time-frequency resources of the reference signal.
Specifically, the receiving end may detect all possible sequences on all possible candidate time-frequency resources according to the configuration of the management entity.

Still taking fig. 6 as an example, assuming that there are K (in fig. 6, K ═ 8) candidate sequences, the value of the lowest 3 bits (first bit segment) of the RS resource ID is determined by the detected sequences. For example, the 1 st sequence is detected, mapped to "000", the 2 nd sequence is detected, mapped to "001", and so on.
The position of the frequency domain resource determines the value of the 4 th bit (second bit segment), and there are 2 possible frequency domain positions in the corresponding frequency domain. For example, a sequence is detected at the 1 st frequency domain position, and the corresponding value is "0"; the sequence is detected at the 2 nd frequency domain position, corresponding to a value of "1".
Assuming that there are L resource locations in the time domain in one period, the time domain resource location where the reference signal is detected is mapped to' aN，…，a4One value of "(third bit segment), for example, a sequence is detected at the 1 st time domain position, mapped to" 00 … 00 "; in the first placeThe 2 time domain positions detect the sequence, mapped to "00 … 01", and so on.
If the first sequence of the reference signal is detected at the 1 st frequency domain position and the 2 nd time domain position, the coded bit of the first bit segment is 000, the coded bit of the second bit segment is 0, and the coded bit of the third bit segment is 00 … 01.
Then, the determined bit segments are combined (for example, the first bit segment, the second bit segment, and the third bit segment are concatenated together) to obtain the reference signal resource identifier.
Preferably, the mapping relationship is configured by a network side device, or agreed by a protocol.
Preferably, the information bits include at least one of:
an identification bit of the transmitting end;
a functional bit of the transmitting end.
Preferably, the information bits transmitted by the transmitting end through the reference signal include at least two information bits, and the step of analyzing the reference signal resource identifier to obtain the information transmitted by the transmitting end through the reference signal includes:

alternatively, the first and second electrodes may be,
de-interleaving the reference signal resource identifier to obtain a de-interleaved reference signal resource identifier;
and analyzing the reference signal resource identifier after de-interleaving to obtain the at least two information bits.
Specifically, if the sending end performs joint coding on at least two information bits to obtain the reference signal resource identifier, the receiving end may decode the reference signal resource identifier to obtain each information bit.
If the sending end carries out cascade connection and interweaving operation on at least two information bits, the receiving end can carry out de-interweaving and splitting on the reference signal resource identification to obtain each information bit.
If the sending end cascades at least two information bits to obtain the reference signal resource identification, the receiving end can split the reference signal resource identification to obtain each information bit.
Still taking fig. 5 as an example, the reference signal resource identifier is parsed to obtain the identification bits (the first N1 bits) of the sender and the functional bits (the last N2 bits) of the sender.
Optionally, the identification bit of the sending end includes at least one of the following: the base station identification number (ID), the identification number (Set ID) of the Set to which the base station belongs, the ID configured for the base station by the network side and the ID of the terminal.
