[0060]

[0061]

[0062] Currently, SRS transmission supports comb 2, comb 4, and comb 8, which respectively indicate that one out of every two subcarriers, one out of every four subcarriers, and one out of every eight subcarriers are used for SRS transmission.

[0063] SRS sequence length It can be calculated using the following formula: Among them, m SRS,b It is through C SRS and B SRS The parameter configuration obtains the full bandwidth of the SRS on an OFDM symbol. Indicates the number of subcarriers in a resource block (RB), K TC It represents comb size. The above comb 2, comb 4, and comb 8 correspond to comb sizes of 2, 4, and 8 respectively.

[0064] The frequency domain position of SRS on an OFDM symbol is determined by n shift and n RRC The parameters are determined by shift is the frequency domain offset value relative to the reference point grid, n RRC It is the SRS bandwidth sending starting position parameter.

[0065] In the existing protocol, the starting position of SRS frequency domain Determined by the following formula:

[0066]

[0067] in:

[0068]

[0069] if and

[0070]

[0071] otherwise,

[0072] n shift is the frequency domain offset value relative to the reference point grid;

[0073] is the number of subcarriers in an RB;

[0074] is port p i comb offset;

[0075] It is an additional offset value agreed upon by the protocol;

[0076] K TC It is the comb size;

[0077] It is the comb offset configured in SRS;

[0078] is the cyclic shift value configured in SRS;

[0079] is the maximum cyclic shift value, which is related to the comb size as agreed by the protocol;

[0080] n b Indicates the frequency domain position index, which is obtained by configuring the parameters in the SRS.

[0081] In addition, SRS supports repeated transmission, where R represents a repetition factor, which represents the number of repetitions of the SRS on a time domain symbol, that is, the complete bandwidth size and frequency domain position of the SRS on multiple repeated OFDM symbols are exactly the same.

[0082] Currently, SRS transmission is based on the SRS transmission position counter n SRS The value of determines the frequency domain position of SRS transmission on each OFDM symbol.

[0083] For aperiodic SRS, the counter of the SRS transmission position .

[0084] For periodic and semi-persistent SRS, a counter of the send position

[0085] Among them, it is necessary to meet

[0086] l′ represents the symbol index of SRS,

[0087] R represents the repetition factor of SRS;

[0088] T offset Represents the period offset of SRS;

[0089] T SRS Represents the period of SRS;

[0090] Represents the number of SRS symbols.

[0091] Among them, the counter n SRS Used in the following formula:

[0092]

[0093] That is, when frequency hopping is turned on, that is, b hop <B SRS When the frequency domain position index n b With n SRS related.

[0094] Currently, there is a discussion on using SRS for partial frequency domain detection on the OFDM symbol of an SRS resource or SRS resource set, that is, sending SRS only on part of the continuous bandwidth of the full bandwidth of the OFDM symbol of an SRS resource or SRS resource set. The possible forms of partial bandwidth are: Among them, P F is the partial bandwidth coefficient, the possible values ​​are 2, 3, 4, 8, etc., and because There may be a phenomenon that the number cannot be divided evenly, and a corresponding rounding method needs to be introduced, such as rounding up, rounding down, rounding up to a multiple of 2, etc. For a partial bandwidth sent by an SRS resource, the full bandwidth on an OFDM symbol can be divided into at least one available starting position by a partial bandwidth coefficient or a bandwidth size agreed upon by the protocol or configured by the network.

[0095] At present, the method for indicating the starting position of a portion of the bandwidth sent by an SRS resource on the OFDM symbol or parameters such as the partial bandwidth coefficient is still unclear. Moreover, once the starting position of the partial bandwidth is determined, the starting position of the partial bandwidth sent by the SRS on an OFDM symbol cannot be changed between multiple transmission cycles or multiple frequency hops, resulting in a reduction in the UE's anti-interference capability, and after using the partial bandwidth transmission method, the bandwidth cannot be fully detected.
