Description

Processing method, communication device and storage medium TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to a processing method, a communication device and a storage medium. BACKGROUND

[0002] In the existing protocol, for UCI (Uplink Control Information) carried on the PUSCH (Physical Uplink Control CHannel), if the uplink resource muting pattern and the UCI resource overlap, the UCI is not transmitted on the corresponding resource according to the muting pattern.

[0003] In the process of conceiving and implementing the present application, the inventors have found that at least the following problems exist:

[0004] If the UCI is not transmitted on the corresponding resource, the number of REs (Resource Elements) used for UCI transmission may be reduced, which in turn causes the UCI transmission performance to decline, so the existing UCI resource processing mechanism needs to be further improved.

[0404] Fourth embodiment

[0405] On the basis of any of the above embodiments of the present application, the fourth embodiment of the present application is proposed, which mainly describes a processing method for determining UCI resources in combination with scenarios.

[0406] This embodiment mainly considers that for the UCI (uplink control information) carried on the PUSCH (physical uplink control channel), if the uplink resource muting pattern and the UCI resource overlap, the UCI does not transmit on the corresponding resource according to the muting pattern, which may reduce the number of REs (resource elements) used for UCI transmission, and further cause the UCI transmission performance to decrease. For the UCI resource mapping on the PUSCH, the RE set that can be used for transmitting the UCI should not contain the RE used for uplink resource muting, so the existing UCI resource processing mechanism needs to be further improved.

[0407] Therefore, the technical solution of the present embodiment is proposed to perfect the UCI resource processing mechanism. For example, the number of modulation symbols (the number of REs) of the UCI is calculated and / or the resource mapping manner of the UCI resource on the PUSCH is redefined to ensure the UCI transmission performance.

[0428] Optionally, the terminal device determines the number of encoded modulation symbols of the uplink control information based on the first parameter, comprising:

[0429] determining a proportion of the uplink control information in all resource elements of the physical uplink shared channel according to a ratio of a bit size of the uplink control information to a bit size of the uplink-data channel;

[0437] Optionally, when the UCI is transmitted on the PUSCH, it can contain HARQ-ACK and CSI. Optionally, in order to ensure the reliability of HARQ-ACK transmission, HARQ-ACK and CSI are independently encoded.

[0440] Optionally, since the length of the sequence after channel coding cannot meet the requirement of all actual mapping RE (resource element) numbers, it is necessary to adaptively adjust the channel coded bits through rate matching so that they can be mapped on all allocated REs, and the above process of calculating the number of UCI coded modulation symbols is rate matching.

[0441] Optionally, the number of REs occupied by each part of independently coded UCI is determined by the ratio of the bit size (including the payload size of CRC) of this part of UCI to the bit size of the uplink-data channel.

[0443] Optionally, considering that the transmission reliability requirement of UCI is higher than that of data transmission, when calculating the proportion of UCI in all RE resources of PUSCH, different code rate compensation factors β offset .

[0520] The technical solution of the present application determines the number of coded modulation symbols of uplink control information by the terminal device based on the first parameter, and perfects the UCI resource processing mechanism.

[0521] Fifth embodiment

[0522] On the basis of any of the above embodiments of the present application, the fifth embodiment of the present application is proposed, which mainly describes a processing method for determining UCI resources in combination with scenarios.

[0523] This embodiment mainly considers that for UCI (uplink control information) carried on PUSCH (physical uplink control channel), if the uplink resource muting pattern and the UCI resource overlap, the UCI is not transmitted on the corresponding resource according to the muting pattern, which may reduce the number of REs (resource elements) used for UCI transmission, and further cause the UCI transmission performance to decrease. Therefore, the existing UCI resource processing mechanism needs to be further improved.

[0524] Therefore, the technical solution of the present application is proposed to perfect the UCI resource processing mechanism. For example, the number of modulation symbols (the number of REs) of UCI is calculated and / or the resource mapping method of UCI resources on PUSCH is redefined to ensure the UCI transmission performance.

[0525] Optionally, the terminal device determines the number of coded modulation symbols of uplink control information based on the first parameter.

[0526] Optionally, the first parameter is provided by a network device.

[0527] Optionally, the network device can be a base station or the like.

[0528] Optionally, the first parameter is determined by the terminal device.

[0529] Optionally, the first parameter is determined through at least one of the following: uplink control information, uplink muting resources, and information related to the uplink-data channel of the physical uplink shared channel.

[0530] Optionally, the uplink control information includes at least one of the following: hybrid automatic repeat request-acknowledgment, channel state information part 1, and channel state information part 2.

[0531] Optionally, the first parameter comprises at least one of:

[0532] a number of hybrid automatic repeat request-acknowledgement bits;

[0533] a number of cyclic redundancy check bits of the hybrid automatic repeat request-acknowledgement;

[0534] a number of channel state information part 1 bits;

[0535] a number of cyclic redundancy check bits of the channel state information part 1;

[0536] a number of channel state information part 2 bits;

[0537] a number of cyclic redundancy check bits of the channel state information part 2;

[0538] a beta offset;

[0539] a number of code blocks of an uplink-data channel in a physical uplink shared channel transmission;

[0540] a size of an rth code block of the uplink-data channel in the physical uplink shared channel transmission;

[0541] a scheduling bandwidth of the physical uplink shared channel transmission;

[0542] a number of subcarriers on an orthogonal frequency division multiplexing symbol l carrying a phase tracking reference signal in the physical uplink shared channel transmission;

[0543] a number of resource elements on an orthogonal frequency division multiplexing symbol l available for carrying uplink control information in the physical uplink shared channel transmission;

[0544] a number of subcarriers on the orthogonal frequency division multiplexing symbol l used for uplink resource cancellation.

[0545] Optionally, the terminal device determines the number of encoded modulation symbols of the uplink control information based on the first parameter, comprising:

[0546] determining a proportion of resource elements occupied by the uplink control information in all resource elements of the physical uplink shared channel according to a ratio of a bit size of the uplink control information to a bit size of the uplink-data channel;

[0547] determining the number of encoded modulation symbols of the uplink control information according to the proportion.

[0548] Optionally, the number of encoded modulation symbols of the uplink control information is determined according to a number of resource elements available for transmitting the uplink control information in the orthogonal frequency division multiplexing symbol before excluding uplink cancellation resources, and an actual number of encoded modulation symbols of the uplink control information is halved on a designated symbol, and optionally, the designated symbol has the uplink control information mapped thereon and has the uplink cancellation resources thereon.

[0549] First part: Calculate the number of coded modulation symbols of UCI.

[0550] Optionally, for the calculation of the number of coded modulation symbols of UCI, the following technical solutions can be adopted:

[0551] Optionally, the number of coded modulation symbols of UCI per layer on PUSCH is calculated according to (i.e. the number of resource elements in the OFDM symbol that can be used for transmitting UCI) before excluding uplink muting (UL muting) resources.

[0552] Optionally, the actual coded modulation symbols of UCI on PUSCH are halved on a specific symbol if UCI is mapped on the symbol and there is uplink muting resource on the symbol.

[0553] Optionally, power boosting is implemented for the resource elements on which UCI is mapped.

[0554] Optionally, the value of power boosting is determined according to the ratio of the total number of resource elements on the symbol to the number of resource elements on which UCI is mapped on the symbol. For example, if the total number of resource elements on the symbol is 12 and the number of resource elements on which UCI is mapped on the symbol is 6, i.e. the ratio is 2, the value of power boosting is 3dB.

[0555] Optionally, the value of power boosting is the logarithm of the ratio of the total number of resource elements on the symbol to the number of resource elements on which UCI is mapped on the symbol. For example, if the total number of resource elements on the symbol is 12 and the number of resource elements on which UCI is mapped on the symbol is X, i.e. the ratio is 12 / X, the value of power boosting is log(12 / X).

[0556] Optionally, the value of power boosting is configured by RRC signaling.

[0557] Optionally, when UCI is transmitted on PUSCH, it can contain HARQ-ACK and CSI.

[0558] Optionally, in order to ensure the reliability of HARQ-ACK transmission, HARQ-ACK and CSI are independently coded.

[0559] Optionally, when CSI is composed of two parts, CSI part 1 and CSI part 2, the two parts are independently coded, the purpose of which is to protect the transmission of CSI part 1 with higher reliability.

[0560] Optionally, when the payload size of UCI bits is greater than 11 bits, a Polar code is used for channel coding; and / or when the payload size of UCI bits is less than or equal to 11 bits, a short code such as a Reed-Muller (RM) code is used.

[0561] Optionally, since the length of the sequence after channel coding cannot meet the requirement of the actual number of mapped REs (resource elements), the channel-coded bits need to be adaptively adjusted through rate matching so as to be mapped on all allocated REs. The above process of calculating the number of UCI coded modulation symbols is rate matching.

[0562] Optionally, the number of REs occupied by each part of independently coded UCI is determined by the ratio of the bit size (including the payload size of CRC) of the part of UCI to the bit size of the uplink-data channel.

[0563] Optionally, when determining the number of REs occupied by each part of independently coded UCI, first, the ratio of the bit size (including the payload size of CRC) of the part of UCI to the bit size of the uplink-data channel is calculated, then, according to the ratio of the bit size (including the payload size of CRC) of the part of UCI to the bit size of the uplink-data channel, the proportion of the part of UCI in the total RE resources of PUSCH is determined, and then the proportion is multiplied by the total RE resources of PUSCH to obtain the number of REs occupied by UCI, i.e., the number of coded modulation symbols of UCI.

[0564] Optionally, considering that the transmission reliability requirement of UCI is higher than that of data transmission, when calculating the proportion of UCI in the total RE resources of PUSCH, different code rate compensation factors β offset .

[0565] Optionally, in order to ensure the transmission of uplink data, UCI does not occupy all RE resources, and this is achieved by introducing a high-layer signaling configured parameter (α) which is used to limit the upper limit of the number of REs occupied by each UCI.

[0645] S2: The network device receives the number of encoded modulation symbols of uplink control information, and the number of encoded modulation symbols is determined by a terminal device based on a first parameter.

[0646] The embodiment mainly considers that for UCI (uplink control information) carried on a PUSCH (physical uplink control channel), if an uplink resource muting pattern and UCI resource overlap, the UCI is not transmitted on the corresponding resource according to the muting pattern, which may reduce the number of REs (resource elements) used for UCI transmission, and further cause the UCI transmission performance to decrease. For UCI resource mapping on the PUSCH, the RE set that can be used for transmitting the UCI should not contain the RE used for uplink resource muting, so the existing UCI resource processing mechanism needs to be further perfected.

[0647] Therefore, the embodiment proposes a solution, and improves the UCI resource processing mechanism. For example, the number of modulation symbols (RE number) of UCI is calculated, and / or the resource mapping manner of UCI resource on PUSCH is redefined, to ensure the UCI transmission performance.
